 Next, the operation will be described.

First, the operation of reading an original will be described with reference to the flowchart of FIG.

When reading a document, the operator sets the handy copier 1 at a position where the document is desired to be read. At this time, the handy copier 1 is set while checking the area to be read on the document from the clear window 15. When the setting of the handy copier 1 is completed, the idle feed button 11 is turned on and the carriage 3 is idle-fed to the position where the reading of the original is desired. At this time, the position of the image sensor unit 4 is visually confirmed from the clear window 15, and when the image sensor unit 4 reaches the position where it is desired to start reading the original, the idle feed button 11 is re-inserted to perform the idle feed of the carriage 3. To stop. During the idling of the carriage 3, the operator can adjust the feed speed of the carriage 3 by adjusting the speed control switch 14, and when the reading start position is approached, the speed control switch 14 is set to SLOW.
When turned to the side, the feed speed of the carriage 3 becomes slower, and the reading start position can be set accurately and easily. As described above, the feed speed of the carriage 3 is controlled by A / D conversion of the adjustment position of the speed control switch 14 and the CPU.
The data is output to the CPU 30, and the CPU 30 causes the carriage 3 to be conveyed at the feed speed corresponding to the adjustment position of the speed control switch 14 based on the internal timer. That is, the CPU 30 is the motor control unit 27
The motor 26 is driven through the carriage 3 to convey the carriage 3 line by line.
Delay corresponding to 14 adjustment positions.

When the image sensor unit 4 is set to the reading start position, the sensor input button 12 is turned on next. When the sensor input button 12 is pressed, as shown in FIG. 7, first, an image for one line is read by the image sensor unit 4 (step S ₁ ), and the read image data is stored in the memory.
The image of the line is stored in 24 and displayed on the LCD 8 (steps S ₂ and S ₃ ). When the storage of the read image in the memory 24 and the display on the LCD 8 are completed, the CPU 30 outputs a drive signal to the motor control unit 27 to sub-scan the carriage 3 for one line. At this time, the CPU 30 uses the internal timer to set the speed. The output of the drive signal to the motor control unit 27 is delayed by the delay time T _D set by the control switch 14 to control the sub-scanning speed (step S ₄ ). When this delay time T _D elapses, the CPU 30 outputs a drive signal to the motor control unit 27, and the motor control unit 27 rotates the motor 26 by one line to move the carriage 3 by one line (for example, 1/8 mm). Only move (step S ₅ ). When the sub-scan is completed, it is checked whether the reading operation is completed, that is, whether the sensor input button 12 is pressed again, or whether the carriage 3 has reached the home position (the right end position in FIG. 1) (step S ₆ ), If the reading operation is not finished, step S ₁
Then, the image for one line is read similarly.
The read image is stored in the memory 24 and displayed on the LCD 8 (steps S ₂ , S ₃ ), delayed by the set time T _D, and then sub-scanned for one line (steps S ₃ , S ₄ , S ₅ ). . Therefore, when approaching the reading end position, the operator can turn the speed control switch 14 to the SLOW side to slow the sub-scanning speed. As a result, the sub-scanning speed is reduced and the LCD8
Confirm the reading end position by the display of and the sensor input button
The reading operation can be ended by re-inputting 12. Therefore, it is possible to accurately, easily, and easily read the desired image on the document.

Next, the operation at the time of image recording will be described with reference to FIGS.

When recording an image, the operator sets the handy copier 1 at a desired recording medium, for example, a notebook or a system notebook. At this time, the handy copier 1 is set while confirming the area to be recorded on the recording medium from the clear window 15 as in the case of reading the original. When the Handy Copier 1 is set, the jump button 11
And the carriage 3 is idly fed to a position where recording on the recording medium is desired to start. Also at this time, clear window 15
The position of the print head unit 5 is visually confirmed from above, and when the print head unit 5 reaches the recording start position, the idle feed button 11 is re-inserted to stop the idle feed of the carriage 3. When the carriage 3 is idly fed, the idling speed can be adjusted by adjusting the speed control switch 14, and the print head unit 5 can be easily and reliably set at the recording start position.

When the print head unit 5 is set to the recording start position, the operator next turns on the print output button 13, and when the print output button 13 is turned on, the CPU 30
Reads out image data for one line (image data first read by the image sensor unit 4) from the memory 24 as shown in FIG. 8 (step P ₁ ). The CPU 30 outputs the image data read from the memory 24 to the LCD 8, displays the image of one line on the LCD 8, and outputs the image data to the print head unit 5 to record one line (steps P ₂ , P ₃ ). When the display of the image for one line on the LCD 8 and the recording on the recording medium are completed, the CPU 30 outputs a drive signal to the motor control unit 27 to move the carriage 3 for one line. At this time, the CPU 30 operates the internal timer. The output of the drive signal to the motor controller 27 is delayed by the delay time T _D set by the speed control switch 14 by the carriage 3
Control the moving speed of (step P ₄ ). This delay time T _D
When the time elapses, the CPU 30 outputs a drive signal to the motor controller 27, and the motor controller 27 rotates the motor 26 by one line to move the carriage 3 by one line (for example, 1/8 mm) (step P ₅ ). When the movement for one line is completed, it is checked whether the recording operation is completed, that is, whether the print output button 13 is turned on again, or whether the carriage 3 has reached the home position (the right end position in FIG. 1) ( If the recording operation is not finished in step P ₆ ), the process returns to step P ₁ and the memory 24
The image data for the line is read out, displayed on the LCD 8, and recorded on the recording medium. This LCD8 display is a memory
The image read from 24 and sequentially recorded along with the recording on the recording medium, the image displayed on the LCD 8 becomes the recorded image.
Therefore, when the operator looks at the display on the LCD 8 and displays all the images to be recorded, the print output button 13
The recording end position can be determined by re-inputting. The display on the LCD 8 is not limited to the method of sequentially displaying only the recorded images. For example, as shown in FIG. 9, all the images in the memory 24 are displayed on the LCD 8,
The position of the recorded image may be specified by setting the image at the current recording position as a black-and-white inverted image (BW).

In this way, the image is displayed and recorded on the LCD 8 and the LC
When the recording end position is approached by D8, speed control switch 14
Can be turned to the SLOW side to slow down the moving speed of the carriage 3. As a result, as shown in FIG. 10, when the recording is ended with "... mas.", The moving speed of the carriage 3 is slowed down, the recording end position is confirmed by the display of the LCD 8, and the print output button 13 is turned on again. By doing so, the recording operation can be ended. Therefore, the image to be recorded can be recorded accurately, easily and easily.

When the LCD 8 has only one line as shown in FIG. 4, the LCD 8 displays the image of the reading line or the image of the recording line.

In the above embodiment, nothing is displayed on the LCD 8 when the carriage 3 is idly fed, but the image sensor unit 4 reads an image of a document or a recording medium and displays it on the LCD 8 even when idling. Good.

(Effect) According to the first invention, after setting the reading start position of the read image of the document stored in the memory, the read image from that position is displayed by the display means, thereby confirming the read image. In addition, by slowing the moving speed of the reading means in the sub-scanning direction near the reading end position, the reading end position can be reliably set. As a result, the reading position and reading range can be accurately set, the image reading apparatus can be handled easily and easily, and the original can be read accurately.

Further, according to the second aspect, after setting the recording start position of the recording image by the recording unit, the recording image from that position can be displayed by the display unit, and the recording image can be confirmed and the recording can be performed. By slowing down the moving speed of the recording means in the sub-scanning direction near the end position,
The recording end position can be set reliably. As a result, the recording position and recording range can be set accurately,
The image recording apparatus can be handled easily and easily, and the image can be recorded accurately.
