Incident light having directivity emitted by the light emitting member 38 is irradiated on the printing paper P when the printing paper P is present in the incident direction, and is irradiated on the platen 26 when the printing paper P is not present in the incident direction. . The 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 is converted into an electric signal as an output value corresponding to the magnitude of the reflected light. That is, since the magnitude of the reflected light of the printing paper P and the platen 26 is different, it is determined whether or not the printing paper P is present in the incident direction of the reflection type optical sensor 29 according to the magnitude of the electric signal obtained from the light receiving member 40. It is possible to determine. The magnitude of the electric signal obtained from the light receiving member 40 is measured by an electric signal measuring unit 66 described later.

For example, it is assumed that the reflection type optical sensor 29 is provided on the left side of the black nozzle # 180 of the print head 36 in FIG.
[0033]
=== Configuration example around the 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 a PF motor) 31 for transporting the printing paper P and a print head 36 for discharging ink onto the printing paper P, and moves in the main scanning direction. A carriage 28, a carriage motor (hereinafter referred to as a CR motor) 30 for driving the carriage 28, a linear encoder 11 provided on the carriage 28, a linear scale 12 having slits formed at predetermined intervals, and printing paper. A platen 26 supporting the P, a paper feed roller 24 for transmitting the driving force of the PF motor 31 to convey the printing paper P in the sub-scanning direction, and a rotary type for detecting the rotation amount of the paper feed roller 24 An encoder 13 (see FIG. 7), a pulley 25 provided on the rotation shaft of the CR motor 30, And a traction belt 32, and a.
[0034]
=== Example of encoder configuration ===
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 has 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 body. 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 (for example, four) of photodiodes 11d, a signal processing circuit 11e, It has two comparators 11fA and 11fB.
[0035]
The light emitting diode 11a emits light when a voltage Vcc is applied through a resistor on the anode side, and this light is incident on 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 parallel light. The parallel light having passed through the slit provided in the linear scale 12 passes through a fixed slit (not shown) and is incident on each photodiode 11d. The photodiode 11d converts the incident light into an electric signal. The electric signals output from the respective photodiodes 11d are compared by comparators 11fA and 11fB, and the comparison result is output as a pulse. Then, the pulses ENC-A and ENC-B output from the comparators 11fA and 11fB are output from the linear encoder 11.
[0036]
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.
[0037]
As shown in FIGS. 6A and 6B, the phase of the pulse ENC-A and the phase of the pulse ENC-B are 90 degrees regardless of whether the CR motor 30 is rotating forward or in reverse. It is out of alignment. 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 greater than the pulse ENC-B as shown in FIG. Only the phase is advanced. On the other hand, when the CR motor 30 is reversed, as shown in FIG. 6B, the phase of the pulse ENC-A is delayed by 90 degrees from the phase of the pulse ENC-B. One cycle T of each pulse is equal to the time during which the carriage 28 moves through the slit interval of the linear scale 12 (for example, 1/180 inch (1 inch = 2.54 cm)).
[0038]
The detection of the position of the carriage 28 is performed as follows. First, a rising edge or a falling edge of the pulse ENC-A or ENC-B is detected, and the number of detected edges is counted. The position of the carriage 28 is calculated based on the counted number. When one edge is detected when the CR motor 30 is rotating forward, “+1” is added to the count number, and when one edge is detected when the CR motor 30 is inverted, “−” is added. 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. Since the period of each 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 is shifted by 90 degrees from the pulse ENC-B, the rising edge of each pulse When the number of detected edges is counted, the counted number “1” corresponds to １ ／ of the slit interval of the linear scale 12. Therefore, if the count number is multiplied by １ ／ 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 １ ／ of the slit interval of the linear scale 12.
[0039]
The detection of the speed Vc of the carriage 28 is performed as follows. First, a rising edge or a falling edge of the pulse ENC-A or ENC-B is detected. On the other hand, the time interval between the edges of the pulse is counted by a timer counter. A period T (T = T1, T2,...) Is obtained from this count value. If the slit interval of the linear scale 12 is λ, the carriage speed can be sequentially obtained 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 the falling edge of each pulse, the time interval between edges corresponding to １ ／ of the slit interval of the linear scale 12 is counted by a timer counter. A period T (T = T1, T2,...) Is obtained from this count value. Then, assuming that the slit interval of the linear scale 12 is λ, the carriage speed Vc can be sequentially obtained as Vc = λ / (4T).
[0040]
Note that the rotary encoder 13 uses a rotating disk (not shown) that rotates in accordance with the rotation of the paper feed roller 24 instead of the linear scale 12 provided on the printer body side, and is provided on the carriage 28. The other configuration is almost the same as that of the linear encoder 11 except that a detector (not shown) provided on the printer main body side is used instead of the detector 14.
[0041]
Further, 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 to convey the printing paper P, a conveyance error occurs due to slippage between the paper feeding roller 24 and the printing 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 and the conveyance error of the conveyance amount of the printing paper P are created, 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, a corresponding transport error is referred from a table, and a correction process for eliminating the transport error is executed. The table may be not only a table in which the rotation amount of the paper feed roller 24 is associated with the transport error of the transport amount of the printing paper P, but may be a table in which the number of transports of the printing paper P is associated with the transport error. Further, since the slip between the paper feed roller 24 and the printing paper P varies depending on the type of paper, a table corresponding to the type of paper may be stored in the memory. As a memory for storing the table, it is desirable to use an EEPROM in which the data can be electrically rewritten in consideration of the possibility of changing the table data in the future.

=== Example of the electrical configuration of the recording apparatus (color inkjet printer) ===
FIG. 7 is a block diagram illustrating an example of an electrical configuration of the color inkjet printer 20. In the color inkjet printer 20, the buffer memory 50 is for temporarily storing a signal supplied from the computer 90. The system controller 54 is supplied with the print data PD and various commands COM temporarily stored in the buffer memory 50. The image buffer 52 supplies the print data PD after the data processing by the system controller 54.

The main memory 56 includes program data for controlling the operation of the color inkjet printer 20 regardless of the interface between the computer 90 and the buffer memory 50, and table data for reference when controlling the operation of the color inkjet printer 20. And the like are stored in advance and are connected to the system controller 54. The main memory 56 may be a nonvolatile storage element (a mask ROM for burning and fixing data in a manufacturing process, an EPROM for erasing data with ultraviolet rays, an EEPROM for electrically rewritable data, or the like), or a volatile storage element. Any of the elements (such as an SRAM capable of holding data with a backup power supply) can be applied, but it is preferable to apply a nonvolatile storage element in that data retention can be guaranteed.
[0044]
The EEPROM 58 rewrites and stores information that changes each time a printing operation is performed, such as the remaining amount of ink, and is connected to the system controller 54.
[0045]
Further, the system controller 54 includes a RAM 57 for storing work data, a main scanning drive circuit 61 for driving the CR motor 30, a sub-scanning drive circuit 62 for driving the PF motor 31, and a print head 36. A head driving circuit 63 for driving, a reflective optical sensor control circuit 65 for controlling the light emitting member 38 and the light receiving member 40 constituting the reflective optical sensor 29, the linear encoder 11, the rotary encoder 13, Is connected. The reflection-type optical sensor control circuit 65 has an electric signal measuring unit 66 for measuring an electric signal corresponding to the magnitude of the reflected light obtained from the light receiving member 40.
[0046]

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 above (the surface opposite to the surface in FIG. 8), and white circles above the paper surface of the print head 36 indicate the black nozzle # 1 and the yellow nozzle # 1. The white circle on the lower side of the print head 36 indicates the black nozzle # 180 and the cyan nozzle # 60.

[0052]
First, in the system controller 54, when the power is turned on, the main scanning drive circuit 61, the sub-scanning drive circuit 62, and the head drive circuit 63 are turned on according to the result of decoding the program data for initialization read from the main memory 56. A control signal for initialization is supplied. Thereby, the carriage 28 is stopped at a predetermined initial position in the main scanning direction by transmitting the driving force of the CR motor 30. That is, the print head 36 provided on the carriage 28 also stops at the same initial position (see FIG. 10A).
[0053]
When the application program 95 receives an instruction to print 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 and outputs the print instruction to the video driver 91 and the video driver 91. The printer driver 96 is controlled. Accordingly, 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 data to the color inkjet printer 20. The color inkjet printer 20 controls the main scanning drive circuit 61, the sub-scanning drive circuit 62, the head drive circuit 63, and the reflection type optical sensor control circuit 65 to print a predetermined image according to the print data PD and various commands COM. A signal is supplied, and the following sequence is executed (S2).
[0054]
The system controller 54 writes the print data PD supplied from the buffer memory 50 to the address A of the RAM 57. Meanwhile, the print data PD includes dot information (binary data of a logical value “1” and a logical value “0”) in the main scanning direction and resolution information (dpi) in the main scanning direction. I have. Therefore, the system controller 54 performs a predetermined operation on the total number of bits of the 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 to the address B of the RAM 57 (S4).
[0055]
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 added to the header of the print data PD, and the system controller 54 may extract the header information from the print data PD to determine the width W1 of the predetermined image.
[0056]
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 in FIG. 10) (S6).
[0057]
The system controller 54 determines whether the upper end of the printing paper P has been transported to the position of the reflection type optical sensor 29. More specifically, the system controller 54 determines whether or not the upper end of the printing paper P is conveyed to the position of the reflection type optical sensor 29 based on the measurement result obtained from the electric signal measurement unit 66 of the reflection type optical sensor control circuit 65. Is determined (S8). Here, the electric signal measuring section 66 included in the reflection type optical sensor control circuit 65 measures the magnitude of the electric signal obtained from the light receiving member 40 and supplies the measurement result to the system controller 54. Note that the measurement result obtained from the electric signal measuring unit 66 becomes a high level (“H”) due to the magnitude of the electric signal of the light receiving member 40 when the light emitting member 38 irradiates the platen 26, and the light emitting member 38 It is assumed that the logic inside the electric signal measuring section 66 is configured so that when P is irradiated, the electric signal of the light receiving member 40 becomes low level (“L”) from the magnitude of the electric signal.
[0058]
When the measurement result obtained from the electric signal measuring unit 66 is at the high level, the system controller 54 determines that the upper end of the printing paper P is not conveyed to the position of the reflection type optical sensor 29 (S8: NO). That is, step 6 is executed again, and the sub-scanning drive circuit 62 drives the PF motor 31 continuously.
[0059]
On the other hand, when the measurement result obtained from the electric signal measurement unit 66 changes from the high level to the low level, the system controller 54 determines that the upper end of the printing paper P has been transported to the position of the reflection type optical sensor 29 ( S8: YES / see FIG. 10 (b)). At this time, the sub-scanning drive circuit 62 stops driving the PF motor 31 (S10).
[0060]
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 by the distance X from the stop position in FIG. 10B to the printing start position and stops. Note that the distance X is a distance set according to conditions such as whether 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, how many mm the edge width is. . For example, when the upper end of the printing paper P is set to have no edge, the distance X is set so that the upper end of the printing paper P becomes the position where the black nozzle # 1 and the yellow nozzle # 1 constituting the print head 36 are arranged. The distance may be 179 kD, or a distance of less than 179 kD to ensure printing (see S12 / FIG. 10C).
[0061]
The system controller 54 supplies 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 to the main scanning drive circuit 61. The main scanning drive circuit 61 drives the CR motor 30 according to the control signal. Accordingly, the carriage 28 starts to move leftward from the initial position, and stops at a position where the reflection type optical sensor 29 irradiates the left side platen 26 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 generates an electric signal for detecting the width W2 of the printing paper P, in other words, the left end and the right end of the printing paper P. It is possible to supply an electric signal that causes a level change at the position of (1) to the reflection-type optical sensor control circuit 65 (S14 / see FIG. 10D).
[0062]
The system controller 54 supplies a control signal for moving the carriage 28 from the left end to the right end of the print paper P to the main scanning drive circuit 61. The main scanning drive circuit 61 drives the CR motor 30 according to the 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 reflection type optical sensor 29 starts an operation for detecting the width W2 of the printing paper P (S16 / see FIG. 10E).
[0063]
The system controller 54 determines whether the reflection type optical sensor 29 is at the left end position of the printing paper P based on the measurement result obtained from the electric signal measurement unit 66 of the reflection type optical sensor control circuit 65 (S18). .
Then, in the system controller 54, when the measurement result obtained from the electric signal measuring unit 66 changes from high level to low level, the reflection type optical sensor 29 changes to a state of irradiating the printing paper P from the platen 26, It is determined that the pattern optical sensor 29 is at the left end position of the printing paper P (S18: YES).
[0064]
The system controller 54 reads 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 high level to the low level, and writes the read value into the address C of the RAM 57. Thereby, the position of the left end of the printing paper P is determined (S20).
[0065]
Similarly, in the system controller 54, based on the measurement result obtained from the electric signal measuring unit 66 of the reflection type optical sensor control circuit 65, it is determined whether the reflection type optical sensor 29 is at the right end position of the printing paper P this time. It is determined whether or not it is (S22).
Then, in the system controller 54, when the measurement result obtained from the electric signal measuring unit 66 changes from low level to high level, the reflection type optical sensor 29 changes to the state of irradiating the platen 26 from the printing paper P, It is determined that the mold optical sensor 29 is at the right end position of the printing paper P (S22: YES).
[0066]
The system controller 54 reads the count value of the linear encoder 11 at the time when the measurement result obtained from the electric signal measuring section 66 changes from low level to high level, and writes the count value into the address D of the RAM 57. Thus, the position of the right end of the printing paper P is determined (S24).
[0067]
The system controller 54 obtains the difference between the count values of the linear encoder 11 stored in the addresses C and D of the RAM 57, and performs a predetermined operation in which the difference is associated with the slit interval λ, thereby obtaining the width W2 of the printing paper P. And writes the width W2 into the address E of the RAM 57 (S26).
[0068]
The system controller 54 supplies a control signal for moving the carriage 28 from the right end of the printing paper P to the left printing start position to the main scanning drive circuit 61. The main scanning drive circuit 61 drives the CR motor 30 according to the control signal. Thus, the carriage 28 moves from the right end of the printing paper P to the left printing start position and stops (S28 / see FIG. 10 (f)).
[0069]
The system controller 54 determines whether the width W2 of the printing paper P is smaller than the width W1 of the predetermined image to be printed (S30).
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 smaller 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, and 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", Supply. Until the printing of the predetermined image is completed, the print data PD sequentially stored at the address A of the RAM 57 is processed in the same manner as described above (S32).
[0070]
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. Until the printing of the predetermined image is completed, the print data PD sequentially stored in the address A of the RAM 57 is processed in the same manner as described above (S34).
[0071]
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. Thereby, the carriage 28 reciprocates in the main scanning direction by transmitting the driving force of the CR motor 30, and the printing paper P is conveyed by the predetermined amount unit in the sub-scanning direction by transmitting the driving force of the PF motor 31. 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, the predetermined image is printed on the printing paper P. Note that the carriage 28 reciprocates in the main scanning direction with a width W1 of a predetermined image to be printed according to information included in the print data PD. However, even if the width W2 of the printing paper P is smaller 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 dot information to the logical value "0", The platen 26 is not stained (S36).
[0072]
The system controller 54 determines whether or not the lower end of the printing paper P has been transported to the position of the reflection type optical sensor 29 based on the measurement result obtained from the electric signal measurement unit 66 of the reflection type 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 electric signal measurement unit 66 changes from low level to high level, the printing paper It is determined that the lower end of P has been transported to the position of the reflective optical sensor 29 (S38: YES / see FIG. 10G). 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 discharge ink (S40). In the sub-scanning drive circuit 62, the PF motor 31 is further driven to discharge the printing paper P (S42).
[0073]
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 according to the control signal. As a result, the carriage 28 moves to the initial position and stops, preparing for the next printing operation (S44 / see FIG. 10H).
[0074]
The reflection type 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.
[0075]
<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 an image in a 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). ). Accordingly, the user sees the print image in which a part of the human face is missing, and realizes that the size of the currently mounted print paper is different from the size of the print paper to be originally mounted. Immediate replacement can be effective. Further, if the edges W2-W3 are added to the printing paper P, the platen 26 can be effectively prevented from being stained (see FIG. 11C).
[0076]
In the printing method of the present embodiment, printing is performed according to 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 a predetermined image to be printed, the printing paper P It is also possible to use the print image of P as it is.
[0077]
By the way, when a predetermined image is printed on the printing paper P, if the width of the printing paper P is shorter than the width of the predetermined image in the direction intersecting with the transport direction of the printing paper P, the printing There is a possibility that the ink corresponding to the information in the portion exceeding the width of P is ejected to the color inkjet printer 20 itself to stain the color inkjet printer 20 itself, and that the printing paper P is wasted.
[0078]
Therefore, in a state where the width of the printing paper P is shorter than the width of the predetermined image to be printed, an image corresponding to the width of the printing paper P or less among the predetermined images is printed on the printing paper P by the print head 36. Therefore, it is possible to prevent the color inkjet printer 20 itself from being soiled and the printing paper P from being wasted.
[0079]
When the width of the printing paper P detected by the reflection type optical sensor 29 is shorter than the width of a predetermined image to be recorded in a direction intersecting the transport direction of the printing paper P, the reflection type optical sensor An image corresponding to the width of the printing paper P detected by the printer 29 may be printed on the printing paper P by the print head 36.
As a result, the predetermined image is printed over the entire width of the printing paper P, so that the color inkjet printer 20 itself becomes dirty due to the ejection of the ink, or the size of the printing paper P It is possible to prevent the printing paper P from being wasted by a simple method of determining that the printing paper P is different.
[0080]
When the width of the printing paper P detected by the reflection type optical sensor 29 is shorter than the width of a predetermined image to be printed in a direction intersecting the transport direction of the printing paper P, the reflection type optical sensor The 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 an edge on the printing paper P, so that the color inkjet printer 20 itself is stained due to the ejection of the ink, or the size of the printing paper P is reduced based on the print content 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.
[0081]
The reflection type optical sensor 29 may move in a direction intersecting with the transport direction of the printing paper P to detect the presence or absence of the printing paper P, and may detect the width of the printing paper P based on the presence or absence of the printing paper P. .
Thereby, the color inkjet printer 20 itself is stained by using the reflection type optical sensor 29 that detects the width of the printing paper P from the presence or absence of the printing paper P in a direction intersecting the transport direction of the printing paper P, or Waste can be prevented.
[0082]
The reflection type optical sensor 29 may be provided together with the print head 36 on the carriage 28 for moving in a direction intersecting with the transport direction of the printing paper P.
Accordingly, the color inkjet printer 20 itself is contaminated by using the reflection type optical sensor 29 provided together with the print head 36 on the carriage 28 for moving in the direction intersecting the transport direction of the printing paper P, or the printing paper P Can be prevented from being wasted.
[0083]
The reflection type optical sensor 29 has a light emitting member 38 for emitting light and a light receiving member 40 for receiving the light emitted by the light emitting member 38. May be detected.
Thus, using the reflection type optical sensor 29 having the light emitting member 38 for emitting light and the light receiving member 40 for receiving the light emitted by the light emitting member 38, the color inkjet printer 20 itself can be stained, P can be prevented from being wasted.
