[0015] Further, the operation of the switching mechanism C is performed by inputting an image by using the scan switch 36. By applying signals to the power, recording means (electronic circuit) and image output means, The drive roller 9 is set in a rotatable state, and the position signal in the sub-scanning direction of image input is input the rotation angle signal of the X-axis motor 13 to the CPU of the control unit (not shown) as Also, when the conveyance roller 12 is switched to a rotatable state, the sub-scanning direction of image output The rotation angle signal of the X-axis motor 13 is given to the CPU as a position signal. It is. Note that the conveyance roller 12 is equipped with a photosensor (not shown) at a suitable position on the conveyance path 3, for example. When it is detected that the image output sheet 2 has been inserted, the switching mechanism C is operated. Then, the drive can be switched to the conveying roller 12.

[0016] Next, the image output unit B transfers the image output sheet 2 to the sub-cover 11. a feed roller 12, the X-axis motor 13 for driving the feed roller 12 (see FIG. 2), A driven roller 14 that follows the conveyance roller 12 is attached.

[0017] Similarly, attach a pen or cutter to the image forming member 15 on the sub-cover 11. a solenoid 16 that moves the forming member 15 up and down with respect to the image output sheet 2; A carriage 17 that supports the component 15 and the solenoid 16, and the front The image forming member 15 and the solenoid 16 are integrally connected in the moving direction (installation) of the image output sheet 2. Guide rails 18, 19, etc. that guide in a direction perpendicular to the The stage is connected to the carriage 17 via a timing belt (not shown) or the like. , the image forming member 15 and the solenoid 16 together with the carriage 17 are connected to a guide rail.

Press lightly to turn on the light source 5 and check the reading position of the image reading surface 1 through the viewing window 25. I approve. At this time, the scan switch 36 does not give a start signal to the X-axis motor 13.

[0023] Next, when the scan switch 36 is strongly pressed, the X-axis motor 13 starts and drives the device of the present invention. As the moving roller 9 rotates, it moves at a constant speed in the scanning direction of arrow M in the figure, and the light source 5 The light irradiates the image reading surface 1, and the reflected light passes through the mirror 6 and lens 7, and then enters the image reading surface 1. The data are input to the image sensor 8 and read sequentially.

[0024] The read image information is accumulated and stored in a storage device (not shown). Like the above When you release the pressure on the switch 36, all operations stop and the previous image is Records input as one screen. The operations up to this point are performed by the image input section A.

[0025] On the image output unit B side, the image output sheet 2 is placed on the conveyance path 3, and the image output sheet 2 is placed in the direction of arrow N. Insert the inserted image output sheet 2 so that it hits the conveyance roller 12. A photosensor (not shown) detects this. Then, the switching mechanism C operates and the crash occurs. The hand plate 32 is switched to the second pulley 31 side, and at the same time, the X-axis motor 13 is driven to move the transfer roller. The image output sheet 2 is placed between the conveyance roller 12 and the driven roller 14. It is gripped and moved to a predetermined position.

[0026] Next, the image signals accumulated and stored in the storage device (not shown) of the image input section A are It is converted into electrical signal pulses by a central processing unit (CPU) (not shown). and , conveyance is driven by the X-axis motor 13 according to a preset control program. The roller 12 is rotated (forward and reverse) to move the image output sheet 2, and the Y-axis motor is The image forming member 15 and the solenoid 16 are attached integrally with the carriage 17 by driving the motor 20. along the guide rails 18, 19 in a direction perpendicular to the moving direction of the image output sheet 2. (reciprocating movement), and the image forming member 15 is moved up and down by the solenoid 16, The image read as one screen by the image input section A is plotted on the image output sheet 2. After outputting the input image data amount, the image output sheet 2 is transferred to the conveyance roller 12. Therefore, all operations are completed by sending the paper in the discharge direction.

[0027] In the above embodiment, the drive roller is used as the drive means in the image input section A. 9 has been described, but in addition to such drive rollers, there are also All or part of these flexible tire-like objects are arranged. can be driven by power from a drive motor. Or the driving hand The crawler track is partially exposed from the bottom cover 4 of the main body as a step, for example, The crawler tracks are arranged at a required distance from the center to both sides, and the crawler tracks are synchronously driven by a drive motor. It can be made so that

[0028] Regarding the drive motor in the drive means, the drive motor of the image input section A and the image output section B is A separate drive motor is used to drive the image output sheet conveying means independently. You can do it like this. Furthermore, as described in the above embodiment, the position of the drive motor 13 is is not only disposed within the lower cover 4 of the main body that covers the image input section A, but also other position and be operated by a power transmission mechanism other than a belt-wrapping drive. can be done.

[Effect of the idea]

As can be understood from the description of the embodiments above, the image processing device of the present invention can This device placed on the reading surface 2 is driven by a drive means operated by a motor. Since the device moves at a constant speed, the image reading speed of the device is stable, and the read image This makes it much easier to obtain copies that are similar to originals without distortion.

[0031] Also, the motor that operates this drive means is connected to the conveying means that conveys the image output sheet. By using a motor, the movement of the device can be done at the same speed as the conveyance of the image output sheet. As a result, it is easy to synchronize the input image and output image. It was easy to do, and distortion between the input image and output image could be eliminated.

[0032] Furthermore, the rotation angle signal of the common drive means is used for the reading signal and the image forming signal. This eliminates distortion caused by differences in the sources of both signals, and allows I was able to successfully eliminate the distortion between the two. Therefore, by doing this again, There is no need to install a separate encoder, which simplifies the internal structure and contributes to downsizing the device. You can donate.
