Description

  The present invention relates to an electronic apparatus and an imaging apparatus having a display screen, and more particularly to an electronic apparatus and an imaging apparatus having a non-contact communication function with an IC tag.

  In recent years, non-contact IC (Integrated Circuit) chips capable of non-contact information exchange with external reader / writers have been widely used. Non-contact IC chips can shorten the processing time from the start of connection to the end of connection due to factors such as no need for physical contact when communicating with a reader / writer, and have high security functions through advanced mutual authentication and encryption processing. It has a feature that it can be easily mounted. For this reason, it is spreading in applications such as electronic money, transportation tickets, and admission cards.

  It is also conceivable that this non-contact type IC chip is mounted on a recording medium such as an optical disk or a memory card so that the recording / reproducing device side can read the stored information in the non-contact type IC chip in a non-contact manner. ing. For example, it is considered that a non-contact type IC chip is mounted on an optical disc, and information about the contents in the optical disc is read from the non-contact type IC chip in a non-contact manner without displaying the optical disc in a recording / reproducing device. It has been. Alternatively, a non-contact type IC chip may be mounted on the memory card so that the recording / reproducing device can identify the type of the memory card and notify the user without inserting the memory card into the card slot. (For example, refer to Patent Document 1).

Recently, mobile phones equipped with the above non-contact type IC chip are also widely used. However, in the future, the mobile phone itself will also be equipped with a reader / writer function to support external non-contact type IC chips. It is also considered to read and write data. As such a portable communication terminal, an antenna module in which a second antenna for communication with an IC tag is formed on the inner peripheral side of a first antenna for communication with a reader / writer is mounted. It has been proposed (see, for example, Patent Document 2).
Japanese Patent Laying-Open No. 2006-246024 (paragraph numbers [0044] to [0045], FIG. 6) JP 2004-364199 A (paragraph numbers [0024] to [0031], FIG. 1)

  By the way, in the recording medium on which the non-contact type IC chip is mounted as described above, the size of the communication antenna of the non-contact type IC chip is limited by the size of the recording medium. For example, when a non-contact type IC chip is mounted on a small memory card, the size of the antenna is very small, and the distance that can be communicated with the reader / writer is about several centimeters to several tens centimeters at most. In such a case, the user operating the recording / reproducing device records data with respect to the antenna of the reader / writer mounted on the device side in order to read the information of the non-contact type IC chip on the recording medium in a non-contact manner. It was necessary to align the antennas on the medium as close as possible and bring them close together.

  In particular, many recording / playback devices that operate with a recording medium mounted thereon, such as a camera-integrated recording / playback device, are provided with a display unit so that the user can usually see the display unit. Operate the recording / playback device in the direction of its own. In this case, when the user reads information from the non-contact type IC chip on the recording medium in a non-contact manner and tries to check the information through the display unit, the recording unit starts recording from a normal state in which the display unit is directed toward the user. Transition to a state in which the antenna of the recording medium can be accurately aligned with the antenna position of the reader / writer on the playback device, and then to the normal state again, the user greatly changes the orientation of the recording / playback device, etc. Will be forced to do complicated work.

  A non-contact type IC chip on a recording medium is often mounted for the purpose of easily reading information in a non-contact manner without mounting the recording medium on a recording / reproducing apparatus. There has been a demand for reducing the complexity as much as possible and further improving the operability for reading information from the non-contact type IC chip.

The monitor unit 102 has a substantially flat plate shape, and a liquid crystal monitor 103 is provided on one surface thereof. The monitor unit 102 is attached to one side surface of the main body unit 101 so as to be opened and closed by rotating in the direction of arrow A in the figure.

  When the monitor unit 102 is closed, the monitor unit 102 is accommodated in the recess 104 formed on the side surface of the main body unit 101. Here, the liquid crystal monitor 103 is used as an example of the monitor, but other thin display devices such as an organic EL (Electroluminescence) display may be used. Furthermore, although not shown in the figure, an antenna coil for non-contact communication, which will be described later, is mounted inside the monitor unit 102.

  An imaging lens 105 is provided on the front surface of the main body 101, and a viewfinder 106 is provided on the back surface. When shooting is performed using the imaging apparatus 100, reflected light from the subject is irradiated to the internal imaging device through the imaging lens 105, and a captured image signal is generated. At this time, an image based on the captured image signal is displayed on the liquid crystal monitor 103 of the monitor unit 102 or a liquid crystal monitor (not shown) in the finder 106, and the user can take a picture while visually recognizing the displayed image. It is also possible to reproduce an image signal recorded on an internal recording medium and display the reproduced image on the liquid crystal monitor 103 of the monitor unit 102.

  In addition, a battery pack 200 in which a secondary battery for driving the imaging device 100 is accommodated is attached to the main body 101 in a detachable state. Further, although not shown, an external recording medium mounting portion on which a portable external recording medium for recording a captured image signal is mounted is formed on the side surface of the main body portion 101 opposite to the mounting surface of the monitor unit 102. ing.

  Further, various input switches are provided on the back surface (surface on which the finder 106 is provided) of the main body 101, and one of them is an IC tag reading switch 107 described later. If the liquid crystal monitor 103 has a so-called touch panel function, the IC tag reading switch 107 may be realized as a virtual switch displayed on the liquid crystal monitor 103.

FIG. 3 is a block diagram illustrating an internal configuration of the imaging apparatus according to the first embodiment.
As shown in FIG. 3, the imaging apparatus 100 includes a camera block 111, a recording / playback processing unit 112, an external recording medium mounting unit 113, a CPU (Central Processing Unit) 114, a memory 115, an input unit 116, a non-contact communication unit 117, A sensor 118, a display control unit 119, and a liquid crystal monitor 103 are provided.

  The camera block 111 includes an optical lens constituting the imaging lens 105, an optical block including a shutter and an iris, an imaging element, an A / D conversion circuit that digitally converts an output signal from the imaging element, and the like.

  The recording / playback processing unit 112 performs various image quality correction processes on the image signal output from the camera block 111 and then outputs the image signal to the display control unit 119 to display the image being shot on the liquid crystal monitor 103. Let Further, when recording of a captured image is requested in accordance with an input operation to the input unit 116, an image signal subjected to image quality correction processing or the like is subjected to recording encoding processing, and then the processed image signal is processed. Is transmitted to the external recording medium mounting unit 113 and recorded on the external recording medium 300 mounted thereon. Further, the image signal read from the external recording medium 300 via the external recording medium mounting unit 113 is decoded, and the processed image signal is output to the display control unit 119, and a reproduced image based on the image signal is displayed. It can also be displayed on the liquid crystal monitor 103.

  When the portable external recording medium 300 is loaded, the external recording medium loading unit 113 reads / writes data from / to the external recording medium 300. In the present embodiment, the external recording medium 300 is an optical disk, and the external recording medium mounting unit 113 is realized as an optical disk drive provided with an optical pickup for reading and writing data from and to the optical disk.

  The CPU 114 is a control unit that comprehensively controls the entire imaging apparatus 100. The CPU 114 is connected to a memory 115 such as a ROM (Read Only Memory) or a RAM (Random Access Memory). The CPU 114 executes a program read from the memory 115 to perform control processing for each unit of the imaging apparatus 100. Do.

  The input unit 116 is provided with various input switches, and the input unit 116 outputs a control signal corresponding to an operation input by the user to the CPU 114. This input switch also includes the above-described IC tag reading switch 107.

  The non-contact communication unit 117 is an RF (Radio Frequency) circuit for performing non-contact communication with the IC tag 301 provided on the external recording medium 300. Here, the non-contact type IC chip and the antenna for the non-contact communication are collectively referred to as “IC tag”.

  The non-contact communication unit 117 includes a modulation circuit 121 that modulates transmission data, a demodulation circuit 122 that demodulates reception data, an antenna switching circuit 123, and the like. In addition, two antenna coils 131 and 132 for communicating with the IC tag 301 are connected to the antenna switching circuit 123, and the antenna switching circuit 123 is connected to one of the antenna coils 131 and 132 in response to a command from the CPU 114. Select only to make it conductive. As these antenna coils 131 and 132, for example, a one-turn loop antenna may be used in addition to the spiral antenna.

  The sensor 118 detects whether or not the external recording medium 300 is mounted on the external recording medium mounting unit 113 and notifies the CPU 114 of the detection result. For example, when the external recording medium 300 is an optical disk, the function of the sensor 118 may be shared by the optical pickup inside the external recording medium mounting unit 113.

  The display control unit 119 generates a display image signal based on the captured image signal and the reproduction image signal from the recording / reproduction processing unit 112, and outputs the image signal to the liquid crystal monitor 103 to display the image. In addition, a function of combining and displaying various images (for example, menu images) output from the CPU 114 is also provided. In FIG. 3, a liquid crystal monitor for displaying a captured image through the finder 106 is omitted. Further, the liquid crystal monitor 103 may be formed as a so-called touch panel that outputs a control signal to the CPU 114 by detecting a user's touch operation on the display surface.

  In addition to the data read / write function for the main storage area of the external recording medium 300, the imaging apparatus 100 also has a data read / write function for the storage area provided in the IC tag 301 mounted on the external recording medium 300. . The non-contact communication unit 117 and the antenna coils 131 and 132 function as a reader / writer for the IC tag 301. Further, here, the IC tag 301 obtains operating power by electromagnetic induction from electromagnetic waves supplied from the non-contact communication unit 117 through the antenna coil 131 or 132.

  The imaging apparatus 100 can read / write data from / to the storage area of the external recording medium 300 while the external recording medium 300 is mounted on the external recording medium mounting unit 113, and at the same time, can be read from the IC tag 301 via the antenna coil 131. Data can be read from and written to the provided storage area. Even when the external recording medium 300 is not mounted on the external recording medium mounting unit 113, the imaging apparatus 100 reads and writes data to and from the storage area of the IC tag 301 mounted on the external recording medium 300. Can be done without contact.

  In the storage area of the external recording medium 300 (a storage area different from the IC tag 301), basically, image data (image content) obtained by imaging with the imaging apparatus 100 is recorded. In the storage area of the IC tag 301, for example, information related to image content recorded on the external recording medium 300 can be recorded. Examples of such information include the file name, recording date and time, recording time, and file capacity of each image content recorded on the external recording medium 300. Further, the remaining capacity of the storage area of the external recording medium 300 may be recorded in the storage area of the IC tag 301.

  FIG. 4 is a diagram for explaining an example of the read / write operation with respect to the IC tag in the imaging apparatus. In the following description, as an example, it is assumed that only data reading from the IC tag 301 is basically performed in communication with the external storage medium 300 through the antenna coil 132.

  As shown in FIG. 4, the imaging apparatus 100 has two types of operation modes of “internal IC tag read / write mode” and “external IC tag read mode” for communication processing with the IC tag 301 mounted on the external recording medium 300. take.

  The internal IC tag read / write mode is an operation mode in which data is read from and written to the storage area of the IC tag 301 via the antenna coil 131 in a state where the external recording medium 300 is mounted on the external recording medium mounting unit 113. In the internal IC tag read / write mode, when the captured image data is recorded in the storage area of the external recording medium 300, the information corresponding to the recording operation is recorded in the storage area of the IC tag 301. Further, when the IC tag reading switch 107 is pressed in the state where the internal IC tag read / write mode is set, the stored information of the IC tag 301 is read through the antenna coil 131 and displayed on the liquid crystal monitor 103.

  The external IC tag reading mode is an operation mode in which data is read from the storage area of the IC tag 301 via the antenna coil 132 when the external recording medium 300 exists outside the imaging apparatus 100. In this external IC tag reading mode, when the IC tag reading switch 107 is pressed, the stored information of the IC tag 301 is read through the antenna coil 132 and displayed on the liquid crystal monitor 103.

  In the imaging apparatus 100, when the sensor 118 detects that the external recording medium 300 is mounted on the external recording medium mounting unit 113, the image capturing apparatus 100 automatically shifts to the internal IC tag read / write mode. Therefore, when the user mounts the external recording medium 300 on the external recording medium mounting unit 113 and immediately presses the IC tag reading switch 107, the IC tag 301 is not read without waiting for the storage area of the external recording medium 300 to be read. The stored information can be immediately confirmed through the liquid crystal monitor 103. Even if the IC tag reading switch 107 is not pressed, the process of reading and displaying information from the IC tag 301 is performed in parallel while reading from the storage area of the external recording medium 300 is being performed. May be.

  Further, when the internal IC tag read / write mode is set, the IC tag read switch 107 can be long-pressed (continue to be pressed for a predetermined time or longer) to shift to the external IC tag read mode. Therefore, even when the external recording medium 300 is mounted on the external recording medium mounting unit 113, the information stored in the IC tag 301 of another external recording medium 300 can be confirmed.

  On the other hand, based on the detection result of the sensor 118, when the external recording medium 300 is not loaded in the external recording medium loading unit 113, the mode automatically shifts to the external IC tag reading mode. Therefore, in this state, the user can confirm the information stored in the IC tag 301 mounted on the external recording medium 300 through the liquid crystal monitor 103 without attaching the external recording medium 300 to the imaging apparatus 100. it can. For this reason, for example, whether or not the external recording medium 300 with a small remaining capacity is mounted on the imaging apparatus 100 or whether the image content desired to be reproduced by the imaging apparatus 100 is recorded on the external recording medium 300 is determined. Can be confirmed in advance.

  As will be described later, when information is read from the IC tag in the external IC tag reading mode, first, display information for instructing a position where the IC tag 301 of the external recording medium 300 is brought close to the imaging device 100 is displayed. It is displayed on the liquid crystal monitor 103. For example, in the internal IC tag read / write mode, this display information is displayed when the IC tag read switch 107 is pressed for a long time to shift to the external IC tag read mode, and then the information read from the IC tag 301 is normally completed. Then, information corresponding to the reading operation is displayed on the liquid crystal monitor 103.

  When it is detected that the external recording medium 300 is removed from the external recording medium mounting unit 113 and the internal IC tag reading / writing mode is changed to the external IC tag reading mode, the display information is automatically displayed on the liquid crystal monitor 103. It may be displayed. As a result, the user can easily recognize that the mode has been changed to the external IC tag reading mode, and the information stored in the IC tag 301 can be shortened through the liquid crystal monitor 103 before the external recording medium 300 is attached to the imaging apparatus 100. Can be confirmed in time.

  In addition, in a state where the external IC tag reading mode is set, the IC tag reading switch 107 can be pressed and held for a transition to the internal IC tag reading / writing mode. In this case, the display information may be automatically deleted from the liquid crystal monitor 103 after the mode transition.

  When the operation mode is switched as described above, the antenna switching circuit 123 automatically selects one of the antenna coils 131 or 132 in accordance with a command from the CPU 114.

  In addition, here, an example in which the information stored in the IC tag 301 is displayed on the liquid crystal monitor 103 has been described, but in addition to this, for example, information associated with information (identification information, etc.) stored in the IC tag 301 May be read from the inside of the imaging apparatus 100 and displayed on the liquid crystal monitor 103. When the imaging apparatus 100 has a function for connecting to a network, information associated with information stored in the IC tag 301 is read from the server via the network, and the information is displayed on the liquid crystal monitor 103. You can also Further, for example, the type of information displayed on the liquid crystal monitor 103 from the information read from the IC tag 301 may be set in advance.

  Next, FIG. 5 is a diagram illustrating a configuration example of an optical disc used in the above imaging apparatus. Here, as an example of the optical disk, a DVD (Digital Versatile Disk) having a diameter of 80 mm, particularly a recordable or rewritable DVD is assumed.

  As shown in FIG. 5, a central hole 311 is provided at the center of the optical disk 310, and when the optical disk 310 is inserted into the optical disk drive, the optical disk 310 is rotated around the central hole 311 so that the signal recording surface Laser light is irradiated, and a signal is read according to the amount of reflected light. In addition, a reflective film made of a conductive material such as Ag (silver) or Al (aluminum), a recording film, a dielectric film, or the like is formed in a region outside the center hole 311 of the optical disk 310 by a predetermined distance. This is a signal recording area 312. Further, the area between the signal recording area 312 and the center hole 311 is an area for chucking the optical disk 310 in the optical disk drive, and is called a chucking area 313 or the like.

  In the chucking area 313, the above-described IC tag 301, that is, the non-contact type IC chip 321 and the non-contact type IC chip 321 communicate with the external reader / writer in a non-contact manner. An antenna coil 322 is provided. In the example of FIG. 5, the antenna coil 322 has a three-turn spiral shape. The antenna coil 322 having such a shape is suitable, for example, when a short wave band represented by 13.56 MHz is used as a communication frequency.

  Note that the antenna for non-contact communication of the non-contact type IC chip 321 has a spiral shape (or loop) around the rotation axis around the center hole 311 in order to maintain a weight balance when the optical disk 310 rotates. It is desirable to be provided. Such an antenna is not limited to the chucking region 313 as shown in FIG. 5, for example, the back surface of the region where the reflective film or the recording film is formed, or the disk substrate at the outer edge of the disk. May be provided.

Next, in the imaging device 100 described above, an operation when information is read from the IC tag 301 through the antenna coil 132 will be specifically described.
When reading information from the non-contact type IC chip 321 on the optical disk 310 existing outside the imaging apparatus 100, an antenna coil 322 connected to the non-contact type IC chip 321 and a reader mounted on the imaging apparatus 100 side. / The optical disk 310 needs to be arranged so that the antenna coil 132 for the writer is close to each other while facing each other. In order to perform good communication at this time, it is desirable that the center of the antenna coil 322 on the optical disc 310 side and the center of the antenna coil 132 on the imaging device 100 side be as close as possible to each other. .

  On the other hand, referring to FIG. 1 and FIG. 2, when shooting is performed using the above-described imaging device 100, the side surface of the main body 101 opposite to the monitor unit 102 is normally held by the user's right hand. . Then, the monitor unit 102 is opened substantially perpendicularly to the main body unit 101, and photographing is performed while the user visually recognizes the liquid crystal monitor 103 facing the rear side of the main body unit 101 (the side on which the finder 106 is attached).

  In order to enable normal communication through the antenna coil 132 with the non-contact type IC chip 321 on the optical disc 310 without changing the basic posture at the time of shooting by the user, the user must It is desirable that the antenna coil 132 on the imaging device 100 side be disposed at a position where the antenna coil 322 on the optical disk 310 is easily aligned while the optical disk 310 is held with the left hand. For this purpose, it is desirable to arrange the antenna coil 132 at a position close to the liquid crystal monitor 103, but it is also required that the display surface of the liquid crystal monitor 103 is not obstructed when the optical disk 310 is aligned.

FIG. 6 is a diagram illustrating an arrangement example of antenna coils in the imaging apparatus.
In this embodiment, as a position satisfying the above condition, as shown in FIG. 6A, the antenna coil 132 on the imaging device 100 side is provided inside the monitor unit 102 and on the display surface of the liquid crystal monitor 103. Place on the back side. Accordingly, the user holds the optical disc 310 with the left hand and brings the optical disc 310 close to the monitor unit 102 so that the non-contact type IC chip 321 on the optical disc 310 can perform communication through the antenna coil 132. It can be so. As shown in FIG. 6B, communication with the non-contact type IC chip 321 is performed by bringing the optical disk 310 close to the back side of the display surface of the liquid crystal monitor 103 in the monitor unit 102, and the liquid crystal The user's line of sight with respect to the monitor 103 is not obstructed.

FIG. 7 is a diagram showing a configuration example of an optical disc case that accommodates the optical disc.
As described above, in order to satisfactorily communicate with the non-contact type IC chip 321 by the antenna coil 132, the center of the antenna coil 322 on the optical disk 310 side and the antenna coil 132 on the imaging device 100 side coincide with each other. It is desirable to be close in state. In this embodiment, in order to enable such alignment work to be performed easily and reliably, communication of the non-contact type IC chip 321 is performed in a state where the optical disk 310 is accommodated in the optical disk case, and the optical disk is A marker is provided on the surface of the case so that the position of the central axis of the internal optical disk 310 can be visually recognized.

  FIG. 7 shows a configuration example of the optical disc case in which the optical disc 310 is accommodated. In the example of FIG. 7A, two linear markers 331a and 331b orthogonal to each other are arranged on a surface parallel to the disk surface of the resin-made optical disk case 330a. In this example, the markers 331 a and 331 b are arranged so that the positions where they intersect each other coincide with the central axis of the optical disc 310.

  In the example of FIG. 7B, four point-like markers 332a to 332d are arranged on a surface parallel to the disk surface of the resin-made optical disk case 330b. In these markers 332a to 332d, the line connecting the markers 332a and 332b and the line connecting the markers 332c and 332d intersect each other vertically, and the intersecting positions thereof coincide with the central axis of the optical disc 310. Is arranged.

  The markers 331a, 331b, 332a to 332d may be drawn on the optical disk case by printing or the like, or may be integrally formed in a convex or concave shape on the case using the same material as the case. Good. Of course, the surface of the optical disc case on which these markers are formed needs to be formed of a non-conductive material so that the two antenna coils can be electromagnetically coupled.

  FIG. 8 is a diagram illustrating an example of a state of the imaging device and the optical disc case when information is read from an IC tag on an external optical disc. Here, as an example, the case where the optical disc case 330a shown in FIG. 7A is used will be described, but the optical disc case 330b shown in FIG. 7B can also be used in the same manner.

  When the IC tag reading switch 107 is pressed in the internal IC tag read / write mode, the imaging apparatus 100 according to the present embodiment first displays display information for instructing the position where the optical disk case is brought close to the liquid crystal monitor 103. . In the example of FIG. 8A, markers 141a to 141c for indicating the positions through which linear markers 331a and 331b arranged on the optical disc case 330a pass are displayed on the liquid crystal monitor 103.

  That is, the optical disk case 330a is aligned and brought close to the back surface of the liquid crystal monitor 103 so that the marker 331a and the markers 141a and 141b overlap, and the marker 331b and the marker 141c overlap, so that the antenna on the optical disk 310 The central axis of the coil 322 and the central axis of the antenna coil 132 on the imaging apparatus 100 side coincide with each other, so that the electromagnetic coupling is reliably performed between the antenna coils. In the example of FIG. 8A, character information for guiding the procedure of alignment work using these markers 141a to 141c is also displayed on the liquid crystal monitor 103.

  When information is normally read from the non-contact type IC chip 321 on the optical disc 310 through the antenna coil 132 in this way, the imaging apparatus 100 reads the read information as shown in FIG. To display. In this example, character information indicating the recording date and time (recording date and time) for each image file recorded in the signal recording area 312 of the optical disc 310 and a bar-shaped image indicating the remaining capacity (disc remaining capacity) in the signal recording area 312 are provided. It is displayed.

  The combination of the position and shape of the marker disposed on the optical disc case and the corresponding instruction image for alignment displayed on the liquid crystal monitor is shown in FIGS. 7 and 8 above. Not limited to this, various other combinations can be applied. In addition, marker images, character information, and the like displayed on the liquid crystal monitor 103 are stored in advance in, for example, the memory 115, read out from the memory 115 and the like under the control of the CPU 114, and output to the display control unit 119. It may be displayed on the liquid crystal monitor 103.

  In the first embodiment described above, the antenna coil 132 for communication with the non-contact type IC chip 321 is provided in the monitor unit 102, and the optical disk 310 on which the non-contact type IC chip 321 is mounted is connected to the back surface of the liquid crystal monitor 103. It is made possible to communicate with the non-contact type IC chip 321 by making it face and approach. As a result, the user holds the main body 101 of the imaging apparatus 100 with the right hand and does not change the state in which the liquid crystal monitor 103 is visually recognized (that is, the state during normal shooting), so that the non-contact IC chip on the optical disc 310 By reading information from 321, the read information can be confirmed through the liquid crystal monitor 103. Therefore, the operability at the time of reading information is improved, and for example, even when the user's photographing work takes a long time, the stress on the work can be reduced.

  In addition, when communicating with the non-contact type IC chip 321 using the antenna coil 132, an instruction image for reliably placing the optical disk case containing the optical disk 310 close to a position where communication can be satisfactorily performed is displayed on the liquid crystal monitor 103. By displaying, it is possible to facilitate the positioning operation by the user. For example, information reading from the non-contact type IC chip 321 can be reliably executed in a short time without the user changing the orientation of the imaging apparatus 100 or greatly distracting from the liquid crystal monitor 103.

  Further, as can be seen from another embodiment described below, it is considered that the position of the antenna coil 132 on the imaging device 100 side is changed for each product, but the position of the antenna coil 132 is thus changed. Even when a variety of different products are provided, it can be dealt with only by changing the data of the instruction image that indicates the position where the optical disk 310 is brought close to. Therefore, the above-described effects can be provided to many products without increasing the product development / manufacturing costs.

FIG. 9 is a diagram illustrating a configuration example of an optical disc used in the imaging apparatus according to the second embodiment. In FIG. 9, the same components as those in FIG. 5 are denoted by the same reference numerals, and description thereof is omitted.

  In the second embodiment, a case where an IC tag of a type in which an antenna coil for noncontact communication is integrally mounted on the same package as a noncontact IC chip will be described. In the example of FIG. 9, such an antenna integrated IC tag 323 is arranged in the chucking region 313 of the optical disk 310 a which is a DVD having a basic structure similar to that of FIG. 5 and having a diameter of 80 mm.

  In such an antenna integrated IC tag 323, the outer diameter of the antenna coil for non-contact communication is usually smaller than that of the optical disk 310 having the configuration used in the first embodiment. For example, an IC tag in which the outer diameter of the antenna coil is about several hundred μm to several mm, which is almost equivalent to the chip size of a non-contact type IC chip, has already been realized.

  When the outer diameter of the antenna coil on the non-contact IC chip side is reduced, it is preferable to reduce the outer diameter of the antenna coil on the reader / writer side in order to increase the coupling rate with the antenna coil. Therefore, in the following FIGS. 10 to 13, configuration examples of the imaging apparatus when the outer diameter of the antenna coil provided in the monitor unit is made smaller than that of the first embodiment will be given. Note that the internal configuration of the imaging apparatus of the present embodiment is the same as that of the imaging apparatus 100 shown in FIG.

In the imaging device 100b shown in FIG. 11, the central axis is parallel to the display surface of the liquid crystal monitor 103 inside the side portion of the monitor unit 102 (that is, the end opposite to the main body unit 101). An antenna coil 132 is provided.

  In this case, for example, as shown in FIG. 11B, an arrow pointing to the side of the monitor unit 102 is used as display information for instructing the position at which the IC tag 323 on the optical disk 310a is brought close to the liquid crystal monitor 103. A marker 142b is displayed in alignment with the central axis of the antenna coil 132. In accordance with this display information, the user places the optical disk 310a or the optical disk case 330 in which the optical disk 310a is stored in close proximity to the side of the monitor unit 102 so that the IC tag 323 and the central axis of the antenna coil 132 are easily and accurately located. Alignment can be performed and reading of stored information can be executed in a short time.

FIG. 12 is a diagram illustrating a configuration of an imaging apparatus according to Embodiment 2-3.
In the imaging apparatus 100 c shown in FIG. 12, an antenna coil 132 is disposed inside the upper part of the monitor unit 102 so that the central axis thereof is parallel to the display surface of the liquid crystal monitor 103.

  In this case, for example, as shown in FIG. 12B, an arrow pointing to the upper side of the monitor unit 102 as display information for instructing the position where the IC tag 323 on the optical disk 310a is brought close to the liquid crystal monitor 103. A marker 142 c is displayed in alignment with the central axis of the antenna coil 132. In accordance with the display information, the user brings the optical disk 310a or the optical disk case 330 in which the optical disk 310a is stored in close proximity to the upper side of the monitor unit 102 so that the IC tag 323 and the central axis of the antenna coil 132 can be easily and accurately positioned. Alignment can be performed and reading of stored information can be executed in a short time.

FIG. 13 is a diagram illustrating a configuration of an imaging apparatus according to Embodiment 2-4.
In the imaging apparatus 100 d shown in FIG. 13, the antenna coil 132 is disposed inside the lower side portion of the monitor unit 102 so that the central axis thereof is parallel to the display surface of the liquid crystal monitor 103.

  In this case, for example, as shown in FIG. 13B, the liquid crystal monitor 103 indicates the lower side of the monitor unit 102 as display information for instructing the position where the IC tag 323 on the optical disc 310a is brought close to. An arrow-shaped marker 142d is displayed in alignment with the central axis of the antenna coil 132. In accordance with this display information, the user makes the optical disc 310a or the optical disc case 330 containing the optical disc 310a close to the lower side of the monitor unit 102 so that the IC tag 323 and the central axis of the antenna coil 132 can be easily and accurately located. The stored information can be read in a short time.

  Note that the optical disk 310a according to the second embodiment can be easily identified when the information is read from the IC tag 323 in the state of being stored in the optical disk case as shown in FIG. An optical disc case provided with a marker for the purpose may be used. When the IC tag 323 is disposed in the chucking area 313, the center of the disk can be easily placed at the position indicated by the marker on the liquid crystal monitor 103 by using the optical disk case as shown in FIG. Therefore, as a result, the IC tag 323 can be easily brought close to the central axis of the antenna coil 132.

  Further, when the external recording medium 300 is stored, if the storage case is configured so that the antenna center of the IC tag 301 on the external recording medium 300 is always arranged at a specific position, it corresponds to the antenna center. A marker for enabling visual identification of the position to be performed can be provided in advance on the outer surface of the storage case. In this case, the liquid crystal monitor 103 displays an instruction image that indicates the position of the marker on the storage case, so that the antenna coil on the external recording medium 300 and the antenna coil 132 on the imaging device side can be electromagnetically satisfactorily. You may make it combine. As such an external recording medium 300, for example, a tape cassette in which a magnetic tape is accommodated is assumed.

[Embodiment 3]
FIG. 14 is a diagram illustrating a configuration example of a memory card used in the third embodiment.
In Embodiment 3, an imaging device using a memory card having a flash memory as the external recording medium 300 will be described. FIG. 14 schematically shows a configuration example in the case where IC tags having two different structures are mounted on such a memory card. 14A and 14B show the left side through the IC tag provided inside the memory card, and the right side shows the outer surface of the memory card. .

  An IC tag including a non-contact IC chip 341 and an antenna coil 342 connected to the outside is mounted on the memory card 340a illustrated in FIG. On the other hand, an IC tag 343 integrated with an antenna coil as shown in FIG. 9 is mounted on the memory card 340b shown in FIG. In these memory cards 340a and 340b, markers 344 and 345 are disposed at corresponding positions on the housing surface so that the user can visually recognize the position of the central axis of the internal antenna coil. In addition, these markers 344 and 345 may be drawn by printing etc. on the housing | casing, for example, or may be integrally formed in convex shape or concave shape on the housing | casing.

  Among these, in the memory card 340b, as described in Embodiment 2, the outer diameter of the antenna coil of the IC tag is very small. Also in the memory card 340a, the outer diameter of the antenna coil 342 is much smaller than that of the configuration of the first embodiment, for example, due to the size restriction of the housing itself. Therefore, the outer diameter of the antenna coil on the reader / writer side for communicating with the IC tags in these memory cards 340a and 340b is also preferably smaller than that in the first embodiment.

  Note that here, the storage area of the IC tag is described as being provided separately from the storage area of the flash memory of the memory card body. It is good also as a structure which can be performed by both the connection via the wire from an external apparatus, and the non-contact connection via an antenna coil. The internal configuration of the imaging apparatus according to the present embodiment is the same as that of the imaging apparatus 100 shown in FIG.

FIG. 15 is a diagram illustrating a configuration example of an imaging apparatus according to the third embodiment. In FIG. 15, the same components as those in FIG. 10 are denoted by the same reference numerals, and description thereof is omitted.
FIG. 15 illustrates a case where an antenna coil 132 is provided on the back side of the liquid crystal monitor 103 as the imaging device 100e using a memory card, as in the imaging device 100a of FIG. In the imaging apparatus 100e, when the IC tag reading switch 107 is pressed in the state of the internal IC tag read / write mode, display information for instructing the position where the IC tag 323 on the optical disk 310a is brought close to the liquid crystal monitor 103 is displayed. Is done. In this example, a dotted marker 143a is displayed at a position corresponding to the central axis of the antenna coil 132, and character information for guiding the user to the operation procedure is displayed.

  As shown in FIG. 15B, the user brings the memory card 340 (referring to the above-mentioned memory card 340a or 340b) close to the back side of the display surface of the liquid crystal monitor 103, and displays the marker 143a displayed. Positioning is performed so that the marker (marker 344 or 345) of the memory card 340 is arranged on the back side. Thereby, the antenna coil in the memory card 340 and the antenna coil 132 on the imaging device 100e side are easily electromagnetically coupled, and the stored information is read.

  Here, as an example, the case where the antenna coil 132 is disposed on the back side of the liquid crystal monitor 103 has been described. However, for example, as shown in FIGS. It may be arranged inside any one of the side part, the upper part and the lower part. The display information on the liquid crystal monitor 103 can be similarly modified. In all these configurations, the user can easily and accurately align the central axes of the antenna coil in the memory card 340 and the antenna coil 132 on the imaging device 100e side, and can read stored information in a short time. Can be executed.

[Embodiment 4]
In the first to third embodiments described above, the electronic apparatus including the monitor unit provided in a state that can be opened and closed with respect to the apparatus main body has been described. However, in the following fourth embodiment, the monitor unit and the apparatus main body are integrated. A case where the present invention is applied to an electronic apparatus configured as described above will be described. Here, a portable phone having a camera function is taken as an example.

  FIG. 16 is a block diagram showing an internal configuration of the mobile phone according to the fourth embodiment. In FIG. 16, blocks having the same functions as those mounted on the imaging apparatus 100 in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted.

  A cellular phone 400 illustrated in FIG. 16 includes a call processing unit 411 that performs processing for a call over wireless, a wireless communication unit 412 that is an RF circuit that performs wireless communication for a call, and voice input / output during a call An audio processing unit 413 that performs processing is provided.

  The call processing unit 411 operates under the control of the CPU 114, and generally controls the call processing via the wireless communication unit 412. For example, audio data is extracted from the data received through the wireless communication unit 412 and output to the audio processing unit 413 to request audio reproduction. Also, the voice data input through the voice processing unit 413 is incorporated into the packet, and is output to the wireless communication unit 412 to request transmission.

  The wireless communication unit 412 includes an antenna for communicating with a base station of a wireless telephone line, and performs demodulation and data separation of a received signal from the antenna, generation and modulation of data to be transmitted, and the like.

  A speaker and a microphone (both not shown) are connected to the audio processing unit 413. The audio processing unit 413 amplifies an audio signal from the microphone, an audio signal output to the speaker, and encodes / decodes the audio signal. Perform processing.

  The mobile phone 400 has the same image capturing function as that of the image capturing apparatus described in the first to third embodiments. In other words, the image signal picked up by the image pickup device in the camera block 111 is supplied as a digital signal to the recording / playback processing unit 112, and from here, a display image signal is output to the display control unit 119. When recording of an image signal is requested in accordance with a user operation input or the like, the image data encoded by the recording / playback processing unit 112 is recorded on the external recording medium 300 via the external recording medium mounting unit 113. . Further, the image signal read from the external recording medium 300 can be decoded by the recording / playback processing unit 112 and the playback image can be displayed on the liquid crystal monitor 103.

  Similarly to the first to third embodiments, the IC tag 301 mounted on the external recording medium 300 has, for example, information on the image content stored in the main storage area of the external recording medium 300 and the remaining storage area. The capacity is recorded. When the external recording medium 300 is mounted on the external recording medium mounting unit 113, data is read from and written to the storage area of the IC tag 301 via the antenna coil 131, and the external recording medium 300 is connected to the mobile phone 400. In the case where it exists outside, the data is read / written from / to the storage area of the IC tag 301 via the antenna coil 132.

  For example, when not only a call process but also an e-mail transmission / reception process is performed through the wireless communication unit 412, the received e-mail data may be recorded in the external recording medium 300. In addition, when it is possible to receive an attached file of an e-mail, data of image content and audio content received as an attached file may be recorded in the external recording medium 300.

  Further, the cellular phone 400 has a communication function with the non-contact type IC card 500 having the IC tag 501 inside the card-type member. The IC tag 501 in the non-contact type IC card 500 obtains operating power from electromagnetic waves supplied from the non-contact communication unit 117 through the antenna coil 133 by electromagnetic induction. Then, the cellular phone 400 reads / writes data from / to the IC tag 501 of the non-contact type IC card 500 via the antenna coil 133.

  In response to a command from the CPU 114, the antenna switching circuit 123 selects only one of the three antenna coils 131 to 133 and transmits / receives a signal. When communication with the non-contact type IC card 500 is performed, for example, when a communication mode with the non-contact type IC card 500 is selected by an input operation to the input unit 116 by the user, the antenna switching circuit 123 is set to the antenna coil. Only 133 is selected to be in a conductive state.

  Here, in this embodiment, the memory card 340 (memory card 340a or 340b) described in Embodiment 3 is used as the external recording medium 300. As described above, the outer diameter of the antenna coil that constitutes the IC tag mounted on the memory card 340 is very small.

  In contrast, the non-contact type IC card 500 has a much larger external casing than the external recording medium 300. For example, ISO (International Organization for Standardization) or JIS (Japanese Industrial Standard) standard defines the outer dimensions of a non-contact type IC card as a long side dimension of 85.6 mm and a short side dimension of 53.98 mm. In such a non-contact type IC card 500, a generally rectangular antenna coil is usually disposed along the outer periphery thereof. For this reason, the outer diameter of the antenna coil constituting the IC tag mounted on the non-contact type IC card 500 is clearly larger than the outer diameter of the antenna coil in the memory card 340.

  As described above, since the outer diameter of the antenna coil included in the external recording medium 300 and the antenna coil included in the non-contact type IC card 500 are greatly different from each other, if the communicable distances are equal to each other, the respective electromagnetic couplings can be well coupled. The outer diameters of the antenna coils on the reader / writer side that can be different from each other are also different. For this reason, the mobile phone 400 has an antenna coil 132 for communication with the IC tag 301 of the external recording medium 300 and an antenna coil 133 for communication with the IC tag 501 of the non-contact type IC card 500. These are provided individually, and these are switched and used.

  Note that the mobile phone 400 of the present embodiment is provided with a non-contact communication function with the external non-contact type IC card 500 as an example, but the mobile phone 400 itself is an IC of the non-contact type IC card 500. The function of the tag 501 may be fulfilled. In this case, the IC tag in the mobile phone 400 operates by receiving a signal from an external reader / writer through the antenna coil 133, and reads / writes data from / to the storage area of the IC tag.

  Even in this case, since many external reader / writers communicating with the antenna coil 133 are optimized so as to be able to communicate with the non-contact type IC card 500, communication with the reader / writer is possible. It is necessary to provide the antenna coil 133 for use separately from the antenna coil 132 for communication with the memory card 340.

  In the following embodiments 4-1 to 4-5, an arrangement example of the antenna coils 132 and 133 in the mobile phone 400 and a screen display example at the time of communication with the memory card 340 will be described. First, FIG. 17 is a diagram illustrating a configuration of a mobile phone according to Embodiment 4-1.

  A mobile phone 400a shown in FIG. 17 communicates with the IC tag of the memory card 340 on the front side of the main body on which the liquid crystal monitor 103, the input panel 421 including various input keys, and the like are arranged, and the imaging lens 422 of the camera. Is communicated with the non-contact type IC card 500 on the back side of the main body on which is provided. In FIG. 17, the positions of the antenna coils 132 and 133 are shown transparently.

  When the cellular phone 400a is used, the user usually holds the cellular phone 400a while viewing the display information with the liquid crystal monitor 103 directed toward the user. Therefore, even when communication is performed with the IC tag of the memory card 340 existing outside the mobile phone 400a or the IC tag 501 of the non-contact type IC card 500, the work for this can be performed in the above basic posture. It is desirable.

  In particular, since the outer diameter of the antenna coil 132 for communication with the IC tag of the memory card 340 is small, it is necessary to align the memory card 340 with respect to the antenna coil 132 more accurately when communicating with the IC tag. There is a need to facilitate this alignment work. Further, when reading information from the IC tag of the memory card 340, the read information is confirmed through the liquid crystal monitor 103, and immediately after that, the operation of mounting the memory card 340 on the external recording medium mounting unit 113 is performed. Therefore, it is desirable that the reading operation can be performed quickly.

  From such a viewpoint, in the embodiment 4-1 (the same applies to the following embodiments 4-2 and 4-3), the antenna coil 132 for communication with the IC tag of the memory card 340 is attached to the liquid crystal monitor 103. Place them as close as possible. In this example, as shown in FIG. 17, the antenna coil 132 is disposed on the upper left of the liquid crystal monitor 103 so that the central axis thereof is perpendicular to the display surface of the liquid crystal monitor 103. Further, at the time of communication with the IC tag, as will be described later, a display for instructing a position where the memory card 340 is brought close to the liquid crystal monitor 103 is performed to assist the user's work.

FIG. 18 is a diagram illustrating an example of a state of the mobile phone when reading information from the non-contact type IC card.
As shown in FIG. 18, the antenna coil 133 is disposed near the back surface of the casing of the mobile phone 400a. In addition, a marker 423 is disposed on the back surface of the mobile phone 400a at a position corresponding to the central axis of the antenna coil 133. Then, the non-contact type IC card 500 is brought close to the back surface of the mobile phone 400a, and the center portion of the non-contact type IC card 500 is aligned with the marker 423, so that the antenna coil 502 in the non-contact type IC card 500 and the mobile phone Communication can be performed with the antenna coil 133 on the telephone 400a side.

FIG. 19 is a diagram illustrating an example of a state of the mobile phone when reading information from an external memory card.
When the mobile phone 400a transitions to an operation mode in which communication with an IC tag in the external memory card 340 is made, for example, in response to an operation input to the input panel 421, the IC tag on the memory card 340 is displayed on the liquid crystal monitor 103. Display information for instructing a position to approach the is displayed. In the example of FIG. 19A, an arrow-shaped marker 431 pointing to the upper left direction of the liquid crystal monitor 103 is displayed along the central axis of the antenna coil 132, and character information for guiding the user to the operation procedure. Is also displayed.

  The user brings the memory card 340 close to the surface of the mobile phone 400a. At this time, the alignment is performed so that the marker 346 indicating the center position of the antenna coil of the IC tag arranged on the memory card 340 is arranged in the direction indicated by the marker 431 displayed on the liquid crystal monitor 103 (FIG. 19). (See (B)). As a result, the antenna coil on the memory card 340 side and the antenna coil 132 on the mobile phone 400a side are easily electromagnetically coupled, and the stored information is read. In the example of FIG. 19B, the date of image capture and its title are displayed on the liquid crystal monitor 103 as the read information.

  Through such a process, the user can easily position the antenna coil 132 by holding the mobile phone 400a with one hand and holding the memory card 340 with the other hand while viewing the liquid crystal monitor 103. To be able to do that. Therefore, it is possible to reliably display the IC tag storage information in a short time. Further, for example, even if a space for arranging markers for positioning in advance around the liquid crystal monitor 103 cannot be secured, the position where the memory card 340 should be brought close to the display information of the liquid crystal monitor 103 is determined. Since the user can be instructed, the degree of freedom in designing the mobile phone 400a is increased, and the size can be reduced.

FIG. 20 is a diagram showing a configuration of the mobile phone according to Embodiments 4-2 and 4-3.
In cellular phone 400b according to Embodiment 4-2 shown in FIG. 20A, antenna coil 132 is placed above the center of liquid crystal monitor 103 so that the central axis thereof is perpendicular to the display surface of liquid crystal monitor 103. It is arranged.

In the same manner as the IC tag described above, the non-contact type IC 213 reads / writes data from / to the nonvolatile storage area inside the storage area in addition to the function of performing non-contact through the antenna coil 214. This is a so-called dual interface memory chip that can be performed via the charge / discharge control unit 212 and the communication terminal.

  Here, among the functions of the charge / discharge control unit 212, the function of managing the charge / discharge state includes a function of storing information on the charge / discharge operation and the charge state of the battery cell 211 in the non-contact type IC 213. For example, the charging current and discharging current in the battery cell 211 are detected at regular intervals, and the remaining battery capacity is calculated based on them and stored in the non-contact type IC 213. When the battery pack 200a is attached to the imaging device 600, the information is read and transmitted to the imaging device 600. In the imaging apparatus 600, information from the battery pack 200 a is output to the CPU 114 via the power control unit 612, and the remaining battery capacity is displayed on the liquid crystal monitor 103 under the control of the CPU 114.

  Note that the remaining battery capacity may be calculated in the imaging apparatus 600 based on information from the battery pack 200a. In this case, the calculated remaining battery capacity may be transmitted to the charge / discharge control unit 212 via the communication terminal, and this information may be stored in the non-contact type IC 213. Further, instead of or in addition to the remaining battery capacity, the remaining usable time may be displayed on the liquid crystal monitor 103 or stored in the non-contact type IC 213.

FIG. 25 is a diagram illustrating a configuration example of an imaging apparatus according to the fifth embodiment. In FIG. 25, the same components as those in FIG. 10 are denoted by the same reference numerals, and description thereof is omitted.
FIG. 25 illustrates a case where an antenna coil 134 is disposed on the back side of the liquid crystal monitor 103 as the imaging device 600 using the battery pack 200a as in the imaging device 100a of FIG. In the imaging apparatus 600, for example, when the IC tag reading switch 107 is pressed, display information for instructing the position where the non-contact type IC 213 in the battery pack 200a is brought close is displayed on the liquid crystal monitor 103. In this example, a dotted marker 621 is displayed at a position corresponding to the central axis of the antenna coil 134 and character information for guiding the user to the operation procedure is displayed.

  For example, the user holds the main body 101 of the imaging device 600 with the right hand, and holds the battery pack 200 a existing outside the imaging device 600 with the left hand while viewing the liquid crystal monitor 103. Then, as shown in FIG. 25 (B), the end surface of the battery pack 200a on which the marker 221 is disposed is brought close to and opposed to the back side of the display surface of the liquid crystal monitor 103, and the battery is placed on the back side of the displayed marker 621. Positioning is performed so that the marker 221 of the pack 200a is arranged. Thereby, the antenna coil 214 in the battery pack 200a and the antenna coil 134 on the imaging apparatus 600 side are easily electromagnetically coupled, and the stored information is read.

  By such work, for example, when the remaining capacity of the battery pack 200a attached to the imaging device 600 is reduced, the remaining capacity from the non-contact type IC 213 of another battery pack 200a via the antenna coil 134 is reduced. Can be read and confirmed on the liquid crystal monitor 103. That is, before attaching another battery pack 200a to the imaging apparatus 600, the user can immediately confirm whether or not the remaining capacity of the battery pack 200a is sufficiently large by a simple operation. Such an operation can be surely executed without changing the basic posture at the time of imaging.

  Here, as an example, the case where the antenna coil 134 is disposed on the back side of the liquid crystal monitor 103 has been described. However, for example, as shown in FIGS. It may be arranged inside any one of the side part, the upper part and the lower part. The display information on the liquid crystal monitor 103 can be similarly modified. In all these configurations, the user can easily and accurately align the centers of the antenna coil 214 in the battery pack 200a and the antenna coil 134 on the imaging device 600 side, and can read the stored information in a short time. Can be executed.

  In Embodiment 5 described above, the imaging device has been described as an example. However, the present invention is not limited to this, and any electronic device that operates with a battery pack equipped with an IC tag and has a display function can be used. By arranging an antenna coil on the reader / writer side in the vicinity of the display surface and displaying an image indicating the position where the IC tag is brought close to the display surface, reading and writing of information with respect to the IC tag can be performed in a short time with a simple operation. Can be executed.

  Further, not only when the display surface is formed as shown in the example of FIG. 25, but also when the display surface is integrally formed on the apparatus main body as in the fourth embodiment described above, A similar effect can be obtained by applying such a reader / writer function and an instruction image display function. For example, instead of the antenna coil for reading / writing with respect to the IC tag on the memory card in the fourth embodiment, the antenna coil for reading / writing with respect to the IC tag of the battery pack is arranged, As the display processing of the instruction image on the display surface, each aspect shown in the fourth embodiment can be applied.

  In each of the above embodiments, it is assumed that an IC tag that communicates in a short wave band typified by 13.56 MHz is used. However, even when an IC tag that communicates at another communication frequency is used. The present invention is applicable. For example, even when an IC tag that performs communication at a frequency of 2.45 GHz or UHF (Ultra High Frequency) band is mounted on a small recording medium and communication is performed with a reader / writer mounted on a portable electronic device, Since restrictions on the shape and size of the antenna are generated, it is not always possible to arrange an antenna having a suitable size and size on both the reader / writer side and the IC tag side. For this reason, it is difficult to increase the communication distance between the reader / writer and the IC tag. Similarly to the communication in the short wave band described above, the antenna on the IC tag side and the reader / writer side are connected during communication. It is necessary to make it close to the antenna. Therefore, even when an IC tag that performs communication in such a frequency band is applied to each of the above-described embodiments, mutual alignment can be easily performed when antennas are brought close to each other for communication. The effect is obtained.
