  The incident light having directivity emitted from the light emitting member 38 is irradiated to the printing paper P when the printing paper P is present in the incident direction, and is irradiated to the platen 26 when there is no printing paper P in the incident direction. . Incident light applied to the printing paper P or the platen 26 is reflected. The reflected light at this time is received by the light receiving member 40 and converted into an electric signal as an output value corresponding to the magnitude of the reflected light. That is, since the magnitudes of the reflected light of the printing paper P and the platen 26 are different, it is determined whether the printing paper P is in the incident direction of the reflective optical sensor 29 according to the magnitude of the electrical signal obtained from the light receiving member 40. It becomes possible to discriminate. The magnitude of the electrical signal obtained from the light receiving member 40 is measured by an electrical signal measuring unit 66 described later.

=== Example of configuration around carriage ===
FIG. 4 is a diagram illustrating an example of a configuration around the carriage 28 in the color inkjet printer 20. The color inkjet printer 20 is provided with a paper feed motor (hereinafter referred to as PF motor) 31 for transporting the printing paper P and a printing head 36 for ejecting ink onto the printing paper P, and moves in the main scanning direction.

=== Configuration Example of Encoder ===
FIG. 5 is an explanatory diagram of the linear encoder 11.
The linear encoder 11 is for detecting the position of the carriage 28, and includes a linear scale 12 and a detection unit 14.
The linear scale 12 is provided with slits at predetermined intervals (for example, 1/180 inch (1 inch = 2.54 cm)) and is fixed to the printer main body side. The detection unit 14 is provided to face the linear scale 12 and is provided on the carriage 28 side. The detection unit 14 includes a light emitting diode 11a, a collimator lens 11b, and a detection processing unit 11c. The detection processing unit 11c includes a plurality of (for example, four) photodiodes 11d, a signal processing circuit 11e, Two comparators 11fA and 11fB are provided.

  The light emitting diode 11a emits light when a voltage Vcc is applied through an anode-side resistor, and this light enters the collimator lens 11b. The collimator lens 11b converts the light emitted from the light emitting diode 11a into parallel light and irradiates the linear scale 12 with the parallel light. The parallel light that has passed through the slit provided in the linear scale 12 passes through a fixed slit (not shown) and enters each photodiode 11d. The photodiode 11d converts incident light into an electrical signal. The electric signal output from each photodiode 11d is compared in the comparators 11fA and 11fB, and the comparison result is output as a pulse. Then, the pulse ENC-A and the pulse ENC-B output from the comparators 11fA and 11fB become the output of the linear encoder 11.

  FIG. 6 is a timing chart showing waveforms of two types of output signals of the linear encoder 11. FIG. 6A is a timing chart of the waveform of the output signal when the CR motor 30 is rotating forward. FIG. 6B is a timing chart of the waveform of the output signal when the CR motor 30 is reversed.

  As shown in FIGS. 6A and 6B, the phase of the pulse ENC-A and the pulse ENC-B is 90 degrees regardless of whether the CR motor 30 is rotating forward or reverse. It is off. When the CR motor 30 is rotating forward, that is, when the carriage 28 is moving in the main scanning direction, the pulse ENC-A is 90 degrees from the pulse ENC-B as shown in FIG. Only the phase is advanced. On the other hand, when the CR motor 30 is reversed, the phase of the pulse ENC-A is delayed by 90 degrees from the pulse ENC-B, as shown in FIG. One period T of each pulse is equal to the time required for the carriage 28 to move through the slit interval of the linear scale 12 (for example, 1/180 inch (1 inch = 2.54 cm)).

  The position of the carriage 28 is detected as follows. First, with respect to the pulse ENC-A or ENC-B, a rising edge or a falling edge is detected, and the number of detected edges is counted. Based on this count number, the position of the carriage 28 is calculated. The count is incremented by “+1” when one edge is detected while the CR motor 30 is rotating forward, and “−” when one edge is detected when the CR motor 30 is reversed. 1 ”is added. Since the period of the pulse ENC is equal to the slit interval of the linear scale 12, the amount of movement from the position of the carriage 28 when the count number is “0” can be obtained by multiplying the count number by the slit interval. That is, the resolution of the linear encoder 11 in this case is the slit interval of the linear scale 12. Further, the position of the carriage 28 may be detected using both the pulse ENC-A and the pulse ENC-B. Each period of the pulse ENC-A and the pulse ENC-B is equal to the slit interval of the linear scale 12, and the phase of the pulse ENC-A and the pulse ENC-B is shifted by 90 degrees. If the falling edge is detected and the number of detected edges is counted, the count number “1” corresponds to ¼ of the slit interval of the linear scale 12. Therefore, if the count number is multiplied by 1/4 of the slit interval, the movement amount can be obtained from the position of the carriage 28 when the count number is “0”. That is, the resolution of the linear encoder 11 in this case is ¼ of the slit interval of the linear scale 12.

The speed Vc of the carriage 28 is detected as follows. First, a rising edge or a falling edge is detected for the pulse ENC-A or ENC-B. On the other hand, the time interval between the edges of the pulse is counted by a timer counter.
A cycle T (T = T1, T2,...) Is obtained from this count value. When the slit interval of the linear scale 12 is λ, the carriage speed can be obtained sequentially as λ / T. Further, the speed of the carriage 28 may be detected using both the pulse ENC-A and the pulse ENC-B. By detecting the rising edge and falling edge of each pulse, the time interval between edges corresponding to ¼ of the slit interval of the linear scale 12 is counted by the timer counter. A cycle T (T = T1, T2,...) Is obtained from this count value.
When the slit interval of the linear scale 12 is λ, the carriage speed Vc can be obtained sequentially as Vc = λ / (4T).

  The rotary encoder 13 uses a rotating disk (not shown) that rotates according to the rotation of the paper feed roller 24 instead of the linear scale 12 provided on the printer main body side, and is provided on the carriage 28. The other configuration is substantially the same as that of the linear encoder 11 except that a detection unit (not shown) provided on the printer main body side is used instead of the detection unit 14.

  The rotary encoder 13 detects the rotation amount of the paper feed roller 24 and does not directly detect the transport amount of the printing paper P. However, when the paper feed roller 24 rotates and transports the print paper P, a transport error occurs due to slippage between the paper feed roller 24 and the print paper P. Therefore, the rotary encoder 13 cannot directly detect the transport error of the transport amount of the printing paper P. Therefore, a table (not shown) is created in which the rotation amount of the paper feed roller 24 detected by the rotary encoder 13 is associated with the conveyance error of the conveyance amount of the printing paper P, and this table is stored in the memory of the printer main body. ing. Then, based on the rotation amount of the paper feed roller 24 detected by the rotary encoder 13, the corresponding conveyance error is referred from the table, and correction processing for eliminating this conveyance error is executed. The table is not limited to the table that associates the rotation amount of the paper feed roller 24 with the conveyance error of the conveyance amount of the printing paper P, but may associate the number of conveyances of the printing paper P with the conveyance error. Further, since the slip between the paper feed roller 24 and the printing paper P differs depending on the paper type, a table corresponding to the paper type may be stored in the memory. As a memory for storing the table, it is desirable to use an EEPROM capable of electrically rewriting data in consideration of the possibility of changing the table data in the future.

The reflection type optical sensor control circuit 65 has an electric signal measurement unit 66 for measuring an electric signal corresponding to the magnitude of the reflected light obtained from the light receiving member 40.

Thus, the system controller 54 decodes various commands COM supplied from the buffer memory 50, and sends control signals obtained as a result of decoding to the main scanning drive circuit 61, the sub-scanning drive circuit 62, the head drive circuit 63, and the like. Supply as appropriate.
In particular, the head drive circuit 63 reads each color component constituting the print data PD from the image buffer 52 in accordance with a control signal supplied from the system controller 54, and each color (black, black) constituting the print head 36 according to each color component. The nozzle array of yellow, magenta, and cyan) is driven.

  At the time of printing, the printing paper P is intermittently transported in the sub-scanning direction by a predetermined transport amount, and the carriage 28 moves in the main scanning direction during the intermittent transport to eject ink droplets from each nozzle. The

=== Printing Method of the Present Embodiment ===
Next, the printing method of the present embodiment will be described with reference to FIGS. 9, 10, and 11. FIG. 9 is a flowchart for explaining the printing method of the present embodiment. FIG. 10 is a schematic diagram for explaining the positional relationship among the print head 36, the reflective optical sensor 29, and the printing paper P when printing is performed using the printing method of the present embodiment.
In FIG. 10, the print head 36 is viewed from the upper surface (the surface opposite to the surface in FIG. 8), and the white circles on the upper surface of the print head 36 indicate the black nozzle # 1 and the yellow nozzle # 1. The white circles on the lower side of the print head 36 indicate the black nozzle # 180 and the cyan nozzle # 60. Further, the printing paper P is conveyed along the sub-scanning direction from the black nozzle # 180 and cyan nozzle # 60 side when printing is performed (see FIG. 8). FIG. 11 is a diagram illustrating an example of a print image obtained by executing the printing method of the present embodiment. In particular, FIG. 11A shows the relationship between the width W1 for printing an image based on the image data and the width W2 (<W1) of the printing paper P. FIG. 11B shows a state in which an image having a width W2 is printed on the printing paper P from a width W1 without a border. That is, the image of W1-W2 is deleted. FIG. 11C shows a state in which an image having a width W3 (<W2) is printed on the printing paper P with an edge from among images having a width W1. That is, the image of W1-W3 (> W1-W2) is deleted and the edge W2-W3 is attached to the right end.

  First, when the power is turned on, the system controller 54 sends the main scanning drive circuit 61, the sub-scanning drive circuit 62, and the head drive circuit 63 according to the result of decoding the program data for initialization read from the main memory 56. A control signal for initialization is supplied. Accordingly, the carriage 28 is stopped at an initial position determined in advance in the main scanning direction when the driving force of the CR motor 30 is transmitted. That is, the print head 36 provided on the carriage 28 also stops at the same initial position (see FIG. 10A).

  When the application program 95 receives an instruction for printing a predetermined image (for example, an enlarged image of an animal's face) from the user, the application program 95 outputs a print command for printing the predetermined image to output the video driver 91 and The printer driver 96 is controlled. Thus, the printer driver 96 receives image data for printing a predetermined image from the application program 95, processes the data in the form of print data PD and various commands COM, and supplies the processed data to the color inkjet printer 20. The color inkjet printer 20 controls to print a predetermined image on the main scanning drive circuit 61, the sub-scanning drive circuit 62, the head drive circuit 63, and the reflective optical sensor control circuit 65 in accordance with the print data PD and various commands COM. A signal is supplied and the following sequence is executed (S2).

  In the system controller 54, the print data PD supplied from the buffer memory 50 is written in the address A of the RAM 57. By the way, the print data PD has dot information in the main scanning direction (binary data of logical value “1” and logical value “0”) and resolution information (dpi) in the main scanning direction. Yes. Therefore, the system controller 54 performs a predetermined calculation on the total number of bits of binary data in the main scanning direction and the resolution in the main scanning direction to obtain a width W1 of a predetermined image to be printed. W1 is written in the address B of the RAM 57 (S4).

  The method for obtaining the width W1 of the predetermined image to be printed is not limited to the above method. For example, information indicating the width W1 of the predetermined image may be attached to the header of the print data PD, and the system controller 54 may extract the header information from the print data PD and obtain the width W1 of the predetermined image.

  The sub-scanning drive circuit 62 drives the PF motor 31, whereby the printing paper P starts to be conveyed in the sub-scanning direction toward the print head 36 (upward on the paper surface of FIG. 10) (S6).

  The system controller 54 determines whether or not the upper end of the printing paper P has been conveyed to the position of the reflective optical sensor 29. More specifically, the system controller 54 determines whether the upper end of the printing paper P is conveyed to the position of the reflective optical sensor 29 based on the measurement result obtained from the electrical signal measurement unit 66 of the reflective optical sensor control circuit 65. Is discriminated (S8). Here, the electrical signal measuring unit 66 included in the reflective optical sensor control circuit 65 measures the magnitude of the electrical signal obtained from the light receiving member 40 and supplies the measurement result to the system controller 54. The measurement result obtained from the electrical signal measuring unit 66 is high level (“H”) from the magnitude of the electrical signal of the light receiving member 40 when the light emitting member 38 irradiates the platen 26, and the light emitting member 38 is printed paper. It is assumed that the logic inside the electric signal measuring unit 66 is configured so that the level of the electric signal of the light receiving member 40 becomes a low level (“L”) when P is irradiated.

  The system controller 54 determines that the upper end of the printing paper P is not conveyed to the position of the reflective optical sensor 29 when the measurement result obtained from the electrical signal measurement unit 66 is at a high level (S8: NO). That is, step 6 is executed again, and the sub-scanning drive circuit 62 continues to drive the PF motor 31.

  On the other hand, the system controller 54 determines that the upper end of the printing paper P has been transported to the position of the reflective optical sensor 29 when the measurement result obtained from the electrical signal measurement unit 66 changes from the high level to the low level ( S8: YES / see FIG. 10B). At this time, the sub-scanning drive circuit 62 stops driving the PF motor 31 (S10).

The system controller 54 supplies a control signal for conveying the printing paper P to the printing start position to the sub-scanning drive circuit 62 based on the print data PD. In the sub-scanning drive circuit 62, the PF motor 31 is driven, whereby the printing paper P is transported a distance X from the stop position in FIG. 10B to the print start position and stops. The distance X is a distance set according to conditions such as whether or not the upper end side of the printing paper P has an edge, and if the upper end side of the printing paper P has an edge, what is the edge width. .
For example, when the upper end side of the printing paper P is set to have no edge, the distance X is the distance from the upper end of the printing paper P to the arrangement position of the black nozzle # 1 and the yellow nozzle # 1 constituting the print head 36. The distance may be 179 kD, or may be less than 179 kD to ensure printing (see S12 / FIG. 10C).

  The system controller 54 supplies the main scanning drive circuit 61 with a control signal for moving the carriage 28 from the initial position to the left side of the left end of the printing paper P. The main scanning drive circuit 61 drives the CR motor 30 in accordance with this control signal. As a result, the carriage 28 starts to move to the left side from the initial position, and stops at the position where the reflective optical sensor 29 irradiates the platen 26 on the left side of the printing paper P. That is, after that, when the carriage 28 moves to the right in the main scanning direction, the reflection type optical sensor 29 detects the electric signal for detecting the width W2 of the printing paper P, in other words, the left edge and the right edge of the printing paper P. It is possible to supply an electrical signal that causes a level change at the position to the reflective optical sensor control circuit 65 (S14 / see FIG. 10D).

  In the system controller 54, a control signal for moving the carriage 28 from the left side of the left end of the printing paper P to the right end is supplied to the main scanning drive circuit 61. The main scanning drive circuit 61 drives the CR motor 30 in accordance with this control signal. Accordingly, the carriage 28 starts to move from the left side of the left end of the printing paper P to the right side. That is, the reflective optical sensor 29 starts an operation for detecting the width W2 of the printing paper P (see S16 / FIG. 10 (e)).

The system controller 54 determines whether or not the reflective optical sensor 29 is at the left end position of the printing paper P based on the measurement result obtained from the electrical signal measuring unit 66 of the reflective optical sensor control circuit 65 (S18). .
In the system controller 54, when the measurement result obtained from the electrical signal measuring unit 66 changes from the high level to the low level, the reflective optical sensor 29 changes to the state in which the printing paper P is irradiated from the platen 26, and the reflection is reflected. It is determined that the mold optical sensor 29 is at the left end position of the printing paper P (S18: YES).

  In the system controller 54, the count value of the linear encoder 11 at the time when the measurement result obtained from the electrical signal measuring unit 66 changes from the high level to the low level is read and written in the address C of the RAM 57. Thereby, the position of the left end of the printing paper P is determined (S20).

Similarly, in the system controller 54, based on the measurement result obtained from the electrical signal measurement unit 66 of the reflective optical sensor control circuit 65, this time, whether the reflective optical sensor 29 is at the right end position of the printing paper P. It is determined whether or not (S22).
In the system controller 54, when the measurement result obtained from the electrical signal measuring unit 66 changes from the low level to the high level, the reflective optical sensor 29 changes to the state in which the printing paper P irradiates the platen 26, and the reflection is reflected. It is determined that the mold optical sensor 29 is at the right end position of the printing paper P (S22: YES).

  In the system controller 54, the count value of the linear encoder 11 at the time when the measurement result obtained from the electric signal measurement unit 66 changes from the low level to the high level is read and written in the address D of the RAM 57. Thereby, the position of the right end of the printing paper P is determined (S24).

  In the system controller 54, the difference between the count values of the linear encoder 11 stored in the addresses C and D of the RAM 57 is obtained, and a predetermined calculation relating the difference and the slit interval λ is performed to perform the width W2 of the printing paper P. And the width W2 is written in the address E of the RAM 57 (S26).

The system controller 54 supplies the main scanning drive circuit 61 with a control signal for moving the carriage 28 from the right end of the printing paper P to the left printing start position. The main scanning drive circuit 61 drives the CR motor 30 in accordance with this control signal.
As a result, the carriage 28 moves from the right end of the printing paper P to the left printing start position and stops (see S28 / FIG. 10 (f)).

The system controller 54 determines whether or not the width W2 of the printing paper P is less than the width W1 of the predetermined image to be printed (S30).
When the system controller 54 compares the information of the widths W1 and W2 stored in the addresses B and E of the RAM 57 and determines that the width W2 of the printing paper P is less than the width W1 of the predetermined image to be printed ( S30: YES), the print data PD is read from the address A of the RAM 57, the dot information at the position corresponding to the width difference W1-W2 in the print data PD is rewritten to the logical value “0”, and stored in the image buffer 52. Supply. Note that the print data PD sequentially stored in the address A of the RAM 57 is processed in the same manner as described above until the printing of the predetermined image is completed (S32).

  On the other hand, the system controller 54 compares the information of the widths W1 and W2 stored in the addresses B and E of the RAM 57, and determines that the width W2 of the printing paper P is equal to or larger than the width W1 of the predetermined image to be printed. Then (S30: NO), the print data PD is read from the address A of the RAM 57 and supplied to the image buffer 52 as it is. Note that the print data PD sequentially stored in the address A of the RAM 57 is processed in the same manner as described above until the printing of the predetermined image is completed (S34).

  Then, the system controller 54 supplies a control signal for executing printing to the main scanning drive circuit 61, the sub-scanning drive circuit 62, and the head drive circuit 63. Accordingly, the carriage 28 is reciprocated in the main scanning direction by the driving force of the CR motor 30 being transmitted, and the printing paper P is conveyed by the predetermined amount unit in the sub-scanning direction by the driving force of the PF motor 31 being transmitted. The head 36 appropriately discharges ink according to various information included in the print data PD, and these operations are executed at appropriate timing. That is, a predetermined image is printed on the printing paper P. The carriage 28 reciprocates in the main scanning direction with a width W1 of a predetermined image to be printed in accordance with information contained in the print data PD. However, even if the width W2 of the printing paper P is less than the width W1 of the predetermined image to be printed, the image of the width difference W1-W2 is not printed by setting all the dot information to the logical value “0”. The platen 26 is not soiled (S36).

The system controller 54 determines whether or not the lower end of the printing paper P is conveyed to the position of the reflective optical sensor 29 based on the measurement result obtained from the electrical signal measuring unit 66 of the reflective optical sensor control circuit 65 ( S38).
The system controller 54 continues the period in which the carriage 28 reciprocates in the main scanning direction, and when the measurement result obtained from the electrical signal measuring unit 66 changes from low level to high level, the printing paper It is determined that the lower end of P has been conveyed to the position of the reflective optical sensor 29 (S38: YES / see FIG. 10 (g)). At this time, the system controller 54 stops supplying the print data PD to the image buffer 52. As a result, the print head 36 does not eject ink (S40). Further, the sub-scan driving circuit 62 further drives the PF motor 31 to discharge the printing paper P (S42).

  Finally, the system controller 54 supplies a control signal for returning the carriage 28 to the initial position to the main scanning drive circuit 61. The main scanning drive circuit 61 drives the CR motor 30 in accordance with this control signal. As a result, the carriage 28 moves to the initial position and stops to prepare for the next printing operation (see S44 / FIG. 10 (h)).

  The reflective optical sensor 29 may be an individual sensor that detects the upper end, the lower end, the left end, and the right end of the printing paper P.

<Printed image on printing paper P>
When the width W2 of the printing paper P is shorter than the width W1 of the predetermined image to be printed, it is impossible to print the hatched portion on the printing paper P (see FIG. 11A). However, when the printing method of the present embodiment is applied, only the width W2 of the width W1 of the predetermined image to be printed is printed on the printing paper P without soiling the platen 26 (see FIG. 11B). ). As a result, the user notices that the size of the currently loaded printing paper is different from the size of the printing paper that should be loaded, by looking at the printed image with a part of the human face missing. We can cope effectively by exchanging promptly. Further, if the edges W2-W3 are attached to the printing paper P, the platen 26 can be effectively prevented from being stained (see FIG. 11C).

  In the printing method according to the present embodiment, printing is performed in accordance with the width W2 of the printing paper P. Therefore, if the width W2 of the printing paper P is slightly shorter than the width W1 of the predetermined image to be printed, the printing paper. It is also possible to use the P print image as it is.

  By the way, when printing a predetermined image on the printing paper P, in a state where the width of the printing paper P is shorter than the width to print the predetermined image in the direction intersecting the transport direction of the printing paper P, the printing paper of the predetermined images is printed. There is a possibility that ink corresponding to the information of the portion exceeding the width of P is ejected to the color ink jet printer 20 itself to contaminate the color ink jet printer 20 itself and the printing paper P is wasted.

  Therefore, in a state where the width of the printing paper P is shorter than the width for printing the predetermined image, an image corresponding to the width of the printing paper P or less of the predetermined image is printed on the printing paper P by the print head 36. As a result, it is possible to prevent the color inkjet printer 20 itself from becoming dirty or the printing paper P from being wasted.

Further, when the width of the printing paper P detected by the reflective optical sensor 29 is shorter than the width to record the predetermined image in the direction intersecting the conveyance direction of the printing paper P, the reflective optical sensor among the predetermined images. An image corresponding to the width of the print paper P detected by the print head 29 may be printed on the print paper P by the print head 36.
As a result, a predetermined image is printed over the entire width of the printing paper P, so that the color inkjet printer 20 itself is soiled due to ink ejection, or the size of the printing paper P is determined from the printing contents on the printing paper P. It is possible to prevent the printing paper P from being wasted by a simple method of determining that the sizes are different.

Further, when the width of the printing paper P detected by the reflective optical sensor 29 is shorter than the width for printing the predetermined image in the direction intersecting the conveyance direction of the printing paper P, the reflective optical sensor 29 is included in the predetermined image. An image corresponding to the width excluding the edge width from the width of the printing paper P detected by the above may be printed on the printing paper P by the print head 36.
As a result, the predetermined image is printed with a border on the printing paper P, so that the color inkjet printer 20 itself is soiled due to ink ejection, or the size of the printing paper P is determined from the print contents on the printing paper P. It is possible to effectively prevent the printing paper P from being wasted by a simple method of determining the difference.

Further, the reflective optical sensor 29 may move in a direction intersecting with the conveyance direction of the printing paper P to detect the presence or absence of the printing paper P, and detect the width of the printing paper P from the presence or absence of the printing paper P. .
Accordingly, the color ink jet printer 20 itself is stained or the print paper P is removed by using the reflective optical sensor 29 that detects the width of the print paper P from the presence or absence of the print paper P in the direction intersecting the transport direction of the print paper P. It can be prevented from being wasted.

Further, the reflective optical sensor 29 may be provided together with the print head 36 on the carriage 28 for moving in the direction intersecting the transport direction of the print paper P.
As a result, the color ink jet printer 20 itself is soiled by using the reflection type optical sensor 29 provided with the print head 36 on the carriage 28 for moving in the direction intersecting the transport direction of the print paper P, or the print paper P Can be wasted.

The reflective optical sensor 29 has a light emitting member 38 for emitting light and a light receiving member 40 for receiving light emitted from the light emitting member 38, and the printing paper P is based on the output value of the light receiving member 40. It is good also as detecting the presence or absence of.
As a result, the color ink jet printer 20 itself is soiled by using the reflective optical sensor 29 having the light emitting member 38 for emitting light and the light receiving member 40 for receiving the light emitted from the light emitting member 38, or printing paper is used. P can be prevented from being wasted.
