Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile terminal device including a flat panel member that is detachably mounted on an outer surface of a housing, and more particularly (but not limited to), such a mobile phone.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there are models in which a foldable mobile phone can be equipped with a replaceable panel mainly for decoration purposes at a portion corresponding to the back surface (outside) of a liquid crystal display unit. This panel is curved in accordance with the outer shape of the telephone, and has a claw for attaching and detaching, and thus has a relatively complicated shape.
[0003]
[Problems to be solved by the invention]
In contrast, in the application filed on the same date as the present application, the present applicant has proposed a portable terminal device having a flat panel member that can be attached to and detached from the outside of the housing.
[0004]
An object of this invention is to provide the portable terminal device which has a novel mechanism for the attachment or detachment of such a removable flat panel member.
[0005]
[Means for Solving the Problems]
A mobile terminal device with a panel member according to the present invention includes a housing having at least a part of an outer surface formed in a planar shape, and a flat panel that is detachably attached to a part of the outer surface of the housing. A member, a guide member that is provided in the housing and performs positioning on both sides when the panel member is mounted, a locking portion that is provided in the housing and locks one end of the panel member, Always urged by elastic force, While locking the other end of the panel member mounted on the housing, Resisted the elastic force A slide member that releases the lock in response to a slide operation; The panel member is mounted, and when the user releases the locked state by sliding the panel member together with the slide member while applying contact pressure to the other end side of the panel member, The one end of the member is released from the locking portion, and the panel member is rotated around the other end and the one end is detached from the locking portion. It is characterized by that.
[0006]
When the panel member is mounted on the housing, the panel member is locked by the locking portion at the front in the sliding direction of the slide member, and is prevented from falling off by being locked by the slide member at the rear. Further, the latching state can be released by removing the sliding member from the housing. Such a structure eliminates the need for a special structure for locking the claws or the like on the panel member itself.
[0007]
Preferably, there is provided a restricting means for restricting movement in a direction perpendicular to the surface of the panel member in a state where the panel member is mounted. As a result, even if there is a gap between the panel member and its mounting surface, rattling of the panel member is prevented. On the contrary, if there is a slight gap, a sheet-like (or card-like) object can be sandwiched between the panel member and the placement surface, which is convenient.
[0009]
As a specific mechanism for that purpose, the panel member is mounted on the inner side of the panel member while the panel member is mounted. Press from Providing a pressing member In Thus, when the slide member slides to the unlocking position, the panel member is rotated by the pressing force of the pressing member.
[0010]
Alternatively, as another specific mechanism, Some outer surface When the slide member is slid to the unlocking position together with the panel member in a state where the recess is formed at the end on the slide member side and the panel member is mounted, one end of the panel member is formed in the recess. It is also possible to cause the panel member to rotate by dropping.
[0011]
Said Emits light on some outer surfaces A surface light emitting member may be provided. The panel member is mounted so as to cover the light emitting surface of the surface light emitting member.
[0012]
It is desirable that at least a part of the panel member is transparent or translucent. Thereby, the aspect of surface light emission can be changed with the design given to the panel member.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Hereinafter, a mobile phone will be described as an example of the mobile terminal device.
[0014]
FIG. 1 is a perspective view showing the appearance of a mobile phone according to an embodiment of the present invention. This cellular phone 100 is a so-called two-fold type cellular phone in which an upper housing 14 and a lower housing 25 are connected to each other via a hinge portion 18 so as to be opened and closed. The panel member 50 and the sub display unit 19 are detachable on the outer surface of the upper housing 14, that is, on the position behind the main display unit (described later). The sub display unit 19 can be used for displaying the radio wave status, date and time, remaining battery level, and the like. A hinge light emitting portion 48 is provided in a fixed portion of the hinge portion 18, that is, in a non-rotating portion in the center of the hinge portion 18 in the drawing. The panel member 50 is composed of a flat plate member that is at least partially transparent or translucent. The panel member 50 is mounted so as to cover a light emitting surface of a surface light emitting member (described later) located therebelow.
[0015]
FIG. 2 shows a state where the panel member 50 is removed from the mobile phone 100 of FIG. FIG. 3 is a plan view showing this state. In the position where the panel member 50 is present in FIG. The surface of the surface light emitting portion 44 is lowered by one step from the periphery of the upper housing 14 and forms a recess that accommodates the panel member 50. That is, wall-shaped guides 43 slightly higher than the thickness of the panel member 50 are formed on both side portions of the surface light emitting portion 44. The guide 43 functions to perform positioning when the panel member is mounted. Further, a groove 41 (an engaging portion for engaging one end of the panel member) into which the upper end (hinge portion side) of the panel member 50 is recessed is formed in a concave shape on the upper end side of the surface light emitting portion 44. A pressing member 46 that protrudes on the surface from the inside of the upper housing is disposed on the lower end side (opposite to the hinge portion) of the surface light emitting portion 44. Further, a slide member (movable locking member) 47 is provided at the lower end portion of the upper housing 14 in the vicinity of the pressing member 46. The slide member 47 is supported by the upper housing 14 so as to be slidable within a predetermined range in a direction along the guide 43, and is always biased upward (hinge portion side) by an elastic force. Therefore, when the panel member 50 is placed and fixed (locked) on the surface light emitting portion 44, the upper end of the panel member 50 is inserted into the groove 41, and then the slide member 47 is slid downward while the panel member 50 is slid downward. The pressing member 46 is pressed at the lower end of 50, and the slide member 47 is returned to its original position by its elastic force in a state where the panel member 50 is pressed against the surface light emitting portion 44. As a result, the upper side (hinge side) of the slide member 47 covers the lower end surface of the panel member 50 and the panel member 50 is prevented from falling off. The pressing member 46 acts to prevent rattling of the locked panel member 50. In particular, when the panel member mounting portion has a sufficient depth to allow the sheet-like (or card-like) member to be sandwiched between the surface light emitting portion 44 and the panel member 50, the pressing member 46. If there is no pressing member 46 when such a sheet-like member is not sandwiched, the panel member 50 may rattle in a direction perpendicular to the surface. The pressing member 46 functions effectively to restrict such movement of the panel member 50. Such a mechanism is clearly shown in FIG.
[0016]
FIG. 4 is a perspective view showing the appearance of the cellular phone 100 in a state where the upper housing 14 is opened. As can be seen from this figure, a main display portion 16 composed of a liquid crystal display device or the like is provided at the main portion of the inner surface of the upper housing 14, and a speaker portion 12 is provided at the upper end. The lower casing 25 is provided with a jog dial 20 for user operation and various operation keys 28 over the entire inner surface, and further, a microphone section 32 is provided at the lower end. In this configuration, it should be noted that the hinge light emitting portion 48 of the hinge portion 18 can be visually recognized in a state where the upper housing 14 is opened, as will be described in detail later.
[0017]
FIG. 5 shows a configuration example of the panel member 50 and the surface light emitting unit 44.
[0018]
As described above, the panel member 50 is formed of a flat plate member that is at least partially transparent or translucent. The surface light emitting unit 44 includes two conversion units 51 including a prism that converts an optical path of light from a light source (in this embodiment, a light emitting diode (LED)), and the conversion unit 51 is connected to the apex portion. It comprises a light guide plate 44a and a reflecting plate 45 disposed on the lower surface of the light guide plate 44a. If the light from the light source can be directly introduced into the light guide plate 44a, the conversion unit 51 can be omitted. The light source in this embodiment is a set of RGB color LEDs, and the emission intensity of each color can be variably controlled. Thereby, light emission of many colors is realized. The light guide plate 44a is a flat plate member having substantially the same shape as the panel member 50 and formed of a light transmitting member, and has a fine processing pattern on the lower surface in order to scatter light. The reflection plate 45 is a white sheet-like member, and reflects the light downward in the vertical direction of the light guide plate 44a upward. The surface light emitting unit used in the present invention is not limited to such a structure, and may be a color display device using EL (Electroluminessence) or the like, for example.
[0019]
In addition, as for the panel member 50 in this Embodiment, the front edge is curving concavely. This is not necessarily a necessary condition, but the front and rear of the panel member can be distinguished, light can be efficiently guided from the two light sources to the light guide plate 44a, and the area of the panel member can be avoided while avoiding the area of the sub display unit 19. It has the advantage that the area can be expanded.
[0020]
FIG. 6A is an exploded perspective view for explaining a mechanical structure related to the slide member 47. The upper casing 14 is provided with two pairs of slide grooves 62 and 63 on the surface of the lower end thereof in the longitudinal direction (the direction along the longitudinal direction of the casing). The slide member 47 is a horizontally long member having a slightly curved surface. On the back side of the slide member 47, two pairs of vertically long protrusions 68 and 69 penetrating the slide grooves 62 and 63 are provided. When the slide member 47 is mounted on the upper housing 14 so that the vertically long protrusions 68 and 69 pass through the corresponding slide grooves 62 and 63, the claw portions provided on the outer side surface of the vertically long protrusion 69 slide. Locked to the edges of the grooves 62, 63. This prevents the slide member 47 from falling off the upper housing 14. When the slide member 47 is removed from the upper housing 14, the vertically long protrusions 68 and 69 facing each other are bent so as to approach each other, and the claw part is removed from the slide groove 62 and pushed out. Similarly, the through hole 72 provided in the upper housing 14 is a hole through which the above-described pressing member 46 passes. The pressing force of the pressing member 46 is obtained by a leaf spring 70 disposed on the back surface of the upper housing 14. Similarly, an elastic pin (elastic member) 67 disposed on the back surface of the upper housing 14 constitutes an urging means that constantly applies an urging force to the slide member 47 toward the upper side (the hinge portion side). The through-hole 65 provided on the lower side of the through-hole 72 is for assisting the attachment of the elastic pin 67 as will be described later.
[0021]
FIG. 6B shows a state of the back side of the portion shown in FIG. In this figure, the tips of the vertically long projections 68 and 69 that pass through the slide grooves 62 and 63 can be seen. A lug 61 is provided between the slide grooves 62 and 63 for guiding the slide member 47 when sliding. The central portion of the elastic pin 67 is locked and fixed to a protrusion 64 provided in the through hole 65 portion. Further, both ends of the pin are engaged with the lower end portion of the vertically long projecting portion 69. Therefore, the vertically long protrusions 68 and 69 are always urged above the slide grooves 62 and 63 (on the hinge side) by the elastic force of the elastic pin 67. The slide member 47 slides downward against the elastic force of the elastic pin 67 only when the user applies a force downward (direction opposite to the hinge portion) to the slide member 47 with a thumb, for example. When the user releases the finger from the slide member 47, the slide member 47 automatically returns to the original position. One end of the plate spring 70 is fixed to the housing 14, and the pressing member is pressed to the outside through the through hole 72 on one surface of the free end.
[0022]
A user operation when removing the panel member 50 from the upper housing 14 will be described with reference to FIGS. FIG. 7 shows a state of the entire apparatus when the panel member is removed. FIG. 8 shows an example of a mechanism for realizing such an operation. FIG. 8A shows a locked state of the panel member 50, and FIG. 8B shows a state when the panel member 50 is removed. This represents a state in the middle of a user operation. In addition, the ratio of the thickness and the length of the panel member 50 and the surface light emission part 44 in a figure is not the same as an actual, but is shown thicker than the actual for convenience. The user supports the folded cellular phone with one hand and moves the slide member 47 in the end direction while applying contact pressure (or frictional force) to the end of the panel member 50 with the other hand, for example, the thumb 89. As a result, the concave tip portion of the panel member 50 is detached from the groove 41. At the same time, the upper end (hinge side) edge of the slide member 47 is retracted, so that the force for suppressing the pressing force of the pressing member 46 via the panel member 50 is weakened. Therefore, when the front end of the pressing member 46 that has been pushed in by the panel member 50 projects vertically upward, the concave front end portion of the panel member 50 rises. Thus, the panel member 50 can be easily removed.
[0023]
Since the panel member 50 in the present invention has a simple flat plate shape and is mounted so as to be fitted into the recess on the surface light emitting portion 44, the panel tip 50 is lifted. Is very convenient for removing the panel member 50.
[0024]
FIG. 9 shows an example of a mechanism for lifting the front end of the panel member 50 when the pressing member 46 is not provided. In this case, when the slide member 47 is retracted from the locked state of FIG. 9A as shown in FIG. 9B, the front end (left side of the figure) of the panel member 50 is detached from the groove 41 and the user's When the rear end (right side in the figure) of the panel member 50 falls into the concave portion 99 provided on the rear end side of the surface light emitting portion 44 by the finger pressing force, the front end of the panel member 50 jumps up.
[0025]
Note that the mechanism itself for attaching and detaching the panel member 50 described in FIGS. 6 to 9 does not require a communication function, and can be applied to any device that attaches and detaches a flat panel member.
[0026]
In FIG. 10, the structural example of the hinge light emission part 48 is shown. This is made of a light guide member curved in a semi-cylindrical shape at the hinge portion, and light from a light source such as an LED is introduced from a part of the light guide member. The number of light sources is not particularly limited. With this configuration, the light emission of the hinge light emitting portion 48 spreads in the circumferential direction, and further from the direction parallel to the surface of the surface light emitting portion 44 when the upper housing is closed, that is, from the direction of the arrow P in FIG. Visible from a vertical direction. The former is a case where the hinge light emitting part 48 is used for incoming notification, and when the hinge part 18 is placed on the upper side, for example, it is stored in a breast pocket, the light emission is visible even from directly above the mouth of the breast pocket. It is useful because it can.
[0027]
The equivalent function of such a hinge light emitting unit is disclosed in Japanese Patent Laid-Open No. 2002-64599. In the present embodiment, the hinge light-emitting part is used in combination with the surface light-emitting part, and has the characteristics described in detail below.
[0028]
Next, FIG. 11 shows a hardware configuration of the mobile phone according to the present embodiment.
[0029]
The mobile phone 100 includes an antenna 200, a duplexer 201, a receiving unit (RX) 202, a transmitting unit (TX) 203, a DSP (Digital Signal Processor) 204, a speaker 205, and a microphone 206 as parts related to the telephone function. Ear receiver 207. The cellular phone 100 further includes a control unit 208, a main display unit 209 (corresponding to 16 in FIG. 1) connected thereto, and a sub display unit 210 (19 in FIG. 2) as parts related to the control of the cellular phone. ), An operation unit 211 (corresponding to 20 and 28 in FIG. 4), a ROM 213, a RAM 214, a surface light emitting unit 44, and a hinge light emitting unit 48. The surface light emitting unit 44 and the hinge light emitting unit 48 include LEDs as described above in the present embodiment. The ROM 213 stores a control program for realizing operations described later in the present embodiment. The ROM 213 may include a writable memory such as a flash ROM.
[0030]
In FIG. 12, four types of light emission patterns A, B, C, and D of the surface light emission part and hinge light emission part in this Embodiment are shown. In the light emission pattern A, the surface light emitting portion is gradually changed from no light emission to dark yellow over time T1 (for example, several seconds), and the density is decreased again to return to no light emission, and the hinge light emitting portion is kept yellow during that time. To do. This pattern, like deep breathing, slowly changes over time from light yellow to dark yellow and from dark yellow to light yellow. In the light emission pattern B, the surface light emitting part is changed to light blue over a period of T2 from no light emission, maintained for T3 hours, and then returned to the state of no light emission over T2 time, while the hinge light emission part starts from light blue and is blue. The system changes repeatedly to nine colors. In this light emission pattern, the color is gradually changed from light cyan to dark cyan so as to imagine a wave, and this is repeated. In the light emission pattern C, both the surface light emitting portion and the hinge light emitting portion are sequentially changed to the constituent colors of the rainbow over a period of T4. This light emission pattern makes an image of a rainbow by gradually changing the rainbow color like orange yellow green blue purple red. In the light emission pattern D, both the surface light emitting portion and the hinge light emitting portion are changed from light green to dark green over time T5, then maintained dark green for T5 hours, and then returned to light green over T5 hours. There is no time emission. This light emission pattern changes colors with a green hue so as to image nature, forests, and the like.
[0031]
In the present specification, the “light emission pattern” refers to any combination of the color and lighting / non-lighting of the surface light emitting portion and the hinge light emitting portion.
[0032]
The light emission patterns listed here are merely examples, and the color, lighting time, order, and the like are not limited to these. In addition to the above, for example, various colors can be switched rapidly in a short time, and the light emission pattern looks like a graffiti, or the opposite colors of red and green are emitted alternately to produce intensity. Or a light emission pattern that intentionally stops light emission is also conceivable.
[0033]
In addition, depending on the configuration (color, transparency) of the panel member, it is possible to make the light shine in a different impression even with the same light. For example, a pattern that cannot be seen only with the panel pattern can be combined with a light emission pattern so that it can be seen as a new pattern.
[0034]
In the example of FIG. 12, the surface light emitting unit and the hinge light emitting unit are operated simultaneously, but it is also possible to operate only one of them.
[0035]
Note that it is also possible to change the incoming pattern only by changing the panel member by providing the panel member itself with light emission pattern information. For this purpose, for example, individual panel members (or types) are used for cellular phones by using shape changes such as protrusions, recesses, and notches encoded on the panel members, or combinations of encoded electrical contacts. By identifying with the detector provided on the side, it is possible to designate at least the light emission pattern of the surface light emitting portion according to the panel member (or type).
[0036]
FIG. 13 shows a flowchart of an example of control of the surface light emitting unit and the hinge light emitting unit according to the event of the mobile phone. Here, three examples of incoming, incoming call, and charging are given as events, but it is not always necessary to include all of them.
[0037]
In FIG. 13, when an incoming call is detected (S11, Yes), the surface light emitting portion and the hinge light emitting portion are caused to emit light in the first light emission pattern (S12). When the telephone call is in progress (S13, Yes), the surface light emitting portion and the hinge light emitting portion are caused to emit light with the second light emission pattern (S14). When charging is in progress (S15, Yes), the surface light emitting portion and the hinge light emitting portion are caused to emit light in the third light emission pattern (S16). The light emission during charging is intended to be enjoyed as indoor illumination along with the indication that charging is being performed. Note that, for example, a control example in which the light emission of the hinge light emitting unit is suppressed when a call is in progress and the upper housing is open is also conceivable. In order to detect whether or not the upper housing is opened, a known mechanical or optical switch (not shown) can be used.
[0038]
The first to third light emission patterns shown in FIG. 13 may be set in advance as defaults, or may be variably set by the user. Further, the control mode of each light emission pattern may include a case where light emission of any light emitting unit is suppressed (no light emission is performed at all). In the embodiment in which the surface light emitting portion and the hinge light emitting portion are used in combination, the panel member is not an essential element.
[0039]
As another example of the event, for example, when the caller is known by a caller ID notification or the like, the light emission pattern can be changed according to the caller when an incoming call is received. For this purpose, the user can register the light emission pattern corresponding to the caller registered in the phone book data. Also, the incoming call itself can be distinguished by telephone and e-mail.
[0040]
The example of the design (pattern) of the panel member 50 is shown to Fig.14 (a)-(f). As described later, the panel member 50 can be prepared with an arbitrary pattern made of various patterns and colors. The user can select and use a desired one from these.
[0041]
As a handle of the detachable panel member, a part of the pattern can be made opaque, translucent, or left transparent. For example, the part other than the zebra pattern can be made transparent (d), the part other than the polka dot pattern can be made transparent (a), and the light emitted from the surface light emitting part behind the panel member can be transmitted through the transparent part. The zebra pattern and polka dots can be lined with silk printing to completely block the light. A large number of polka dots may be painted in different colors for each polka dot so that the reflected light of the light from the front surface and the transmitted light of the light from the surface light emitting unit can be enjoyed from the back.
[0042]
Furthermore, a pattern in which a part of the panel member is cut out and something is fitted therein is also conceivable. For example, a part of the panel member may be cut out and a rhinestone may be attached thereto, or a denim fabric may be pulled out and an eyelet may be attached there to transmit light. In the case of an eyelet, light is transmitted as it is, but when a rhinestone or the like is pasted, the effect of shining light is obtained by the shape of the rhinestone.
[0043]
The panel member can be a half mirror. At that time, even if the LED emits light by changing the degree of half near the center and near the edge (for example, gradation), even with the light emission pattern in which the entire panel member is illuminated uniformly through the half mirror Since the light transmission changes, a different appearance can be realized when combined with the panel member.
[0044]
In the case of a pattern that is not backed, half of the light can be transmitted through the colored pattern. In this case, the portion colored by silk printing or the like serves as a filter, and absorbs or transmits the light from the LED. For example, a large number of polka dots may be applied in different colors for each polka dot so that the reflected light of the light from the front surface and the transmitted light of the light from the surface light emitting unit can be enjoyed from the back. Specifically, in the case of a dot pattern, when the red and orange dots are arranged, when the LED shines in cyan (complementary red), the red part appears not shining and only the orange part appears shining. Or Therefore, if a person is dancing in a dot pattern, it is possible to create a pattern in which a dancing person emerges depending on how the LED emits light. Alternatively, if the line pattern is arranged in blue, green, and red, and the LEDs are lit in the order of their complementary colors yellow, magenta, and cyan, the complementary colors appear to shine and the light flows. It can also emit light.
[0045]
The panel member 50 may be a simple colorless (or light) transparent member as a whole. The user can sandwich an arbitrary sheet-like member between the panel member 50 and the surface light emitting unit 44. However, in order to utilize surface light emission, it is preferable that at least a part of the sheet-like member is transparent or translucent. For example, a transparent sheet-like member such as an OHP sheet printed with a photograph, a pattern, characters, and a combination of these and a color can be cut into a predetermined size and used. There is no problem even if the size is smaller than the panel member 50.
[0046]
The preferred embodiment of the present invention has been described above, but various modifications and changes other than those mentioned above are possible. For example, although the embodiment has been described only for a mobile phone, the present invention can be applied to any device using a similar replacement panel member.
[0047]
【The invention's effect】
The panel member attaching / detaching mechanism having a novel structure of the portable terminal device according to the present invention makes the structure of the panel member itself extremely simple, facilitating the creation of a replacement panel member, and reducing the cost. Further, the attachment / detachment and replacement of the panel member, in particular, the detachment operation thereof becomes easy.
