The lowering of the auxiliary roller unit 18 is performed by pulling the roller shaft 20 downward by hand. When the operation knob 6a of the mode changeover switch 6 is switched to the eject position E, the cam groove which moves together with the operation knob 6a. Since the engaging pin 22 comes under the vertical groove 21d of the cam groove 21 of the elevating plate 19, the auxiliary roller unit 18 can be pulled down. Further, the ink ribbon cassette 70 from within the apparatus main body 1 is also provided.
In this case, the supply-side spool engaging shaft 50 that is fitted and engaged with the supply-side spool 74 of the ink ribbon cassette 70 is connected to the brake spring 52.
When the opening / closing lid 1d is opened, the ink ribbon cassette 70 is pushed out along with the supply side spool engaging shaft 50 toward the cassette loading port 1c by the spring force of the brake spring 52, and the ink ribbon cassette 70 is pressed. Side protrudes outside from the cassette loading port 1c, the ink ribbon cassette 70 can be easily extracted.

Next, the circuit board of the control unit 12 in FIG.
The configuration of an electronic circuit formed around 12a will be described with reference to FIG. The main encoder unit 24 includes the rotating disk 26, the rotation amount detection base 27, and the like as described above, and includes a pulse signal corresponding to the movement amount of the apparatus main body 1,
That is, it outputs a movement amount detection signal and a forward / reverse rotation detection signal of the rotating disk 26 corresponding to the moving direction of the apparatus main body 1. The movement amount detection signal output from the main encoder unit 24 is transmitted to the control unit 101, the timing signal generation unit 10

Further, although not shown, the control unit 101 includes a power supply voltage detector inside. The control unit 101 controls the LED unit 10 in response to the operation signal from the key and the switch 107.
7 Power ON display section LED7a, Memory remaining LED7
b. It controls the lighting of the speed warning LED 7c and controls other parts, and gives operation commands R and P to the timing signal generator 102 according to the reading mode or the printing mode designated by the mode changeover switch 6. In this case, the control unit 101 gives the operation command R to the timing signal generation unit 102 in the reading mode and the operation command P in the printing mode.

When an operation command R is given from the control unit 101, the timing signal generation unit 102 generates a CCD exposure timing signal of a fixed cycle and outputs a main encoder unit.
The predetermined number of read timing signals A, serial / parallel conversion signals B,
Various timing signals such as a clock pulse C are generated.
Further, when the operation command P is given from the control unit 101, the timing signal generating unit 102 synchronizes with the movement amount detection signal only when the forward rotation detection signal is given from the main encoder unit 24. Generate a signal. The CCD exposure timing signal output from the timing signal generation unit 102 is a one-dimensional image sensor 57.
The read timing signal A is sent to the A / D converter 109, and the serial / parallel converted signal B is sent to the serial / parallel converter 110.
Then, the clock pulse C is sent to the address counter 111 and the read width memory address control unit 112, respectively.
The one-dimensional image sensor 57 detects reflected light from the document a.
The signal is read out in synchronization with the CCD exposure timing signal, and is output to the A / D converter 109 via the amplifier. This A / D converter 109
The input signal is converted into a monochrome binary signal by the read timing signal A, and output to the serial / parallel converter 110. The serial / parallel converter 110 converts the input signal into a parallel signal, for example, every 8 bits using the serial / parallel conversion signal B, and outputs the parallel signal to the image data memory 114 via the data selector 113. The data line of the data selector 113 is connected to the control unit 101, and one of the serial / parallel conversion unit 110 and the control unit 101 is selected by a select signal D from the control unit 101. The write address (row and column address) of the image data memory 114 is indicated by the read width memory address control unit 112 and specified by the address counter 111. Here, the read width address data based on the operation of the read width designating switch 5 in FIG. 1 is given from the control unit 101 to the read width memory address control unit 112, and the address counter is provided with the number of addresses corresponding to the specified read width. The write designation address by 11 is counted up. That is, only the image data from the zero point on the width scale drawn along the reading width command switch 5 to the scale including the operation knob 5a is written and stored in the image data memory 114. The read address of the image data memory 114 is also given from the control unit 101 via the address counter 111. In this case, too, the read address for one line is printed based on the number of read width addresses set in the read width memory address control unit 112. Is specified. Here, after the start of the reading operation movement, the timing signal generating circuit 102 sets the address counter 111 on the lower surface side of the apparatus main body 1 if the main encoder pulse corresponding to the distance from the reading position to the end in the traveling direction is not provided. Is not generated, the reading data is not actually written to the image data memory 114 until the reading position advances to the end position in the reading direction at the initial setting position of the apparatus main body 1. When the reading of the image data is completed, the address of the image data written in the image data memory 114 corresponding to the distance from the reading position on the lower surface side of the apparatus main body 1 to the end portion in the reverse direction is cleared. Therefore, actually, only the image data is read up to the end in the non-reading direction at the final set position of the apparatus main body 1. That is, the apparatus body 1 shown in FIG.
In the reading state, the image data located between the right end of the main body initial setting position and the left end of the main body final setting position is read.

When the reading of the original is completed and the mode is switched to the print mode, the control unit 101 outputs the operation command P to the timing signal generation unit 102 and the movement amount from the main encoder unit 24 as described above. The data stored in the image data memory 114 is sequentially read via the data selector 113 in accordance with the detection signal. This control unit 101
When the image data is read from the image data memory 114, the energizing time is set based on the head temperature from the temperature sensor 106, the detection data of the power supply voltage detector, and the value of the print density adjustment knob 8, and the thermal head drive as print data Circuit 11
Output to 5. When print data is sent from the control unit 101, the thermal head drive circuit 115 drives the thermal print head 32 in synchronization with a timing signal from the timing signal generation unit 102. Where the motor drive controller
104 supplies an appropriate motor drive pulse signal to the take-up shaft drive motor 41 based on the movement amount detection signal of the apparatus main body 1 from the main encoder unit 24, thereby allowing the supply spool 74 of the ink ribbon cassette 70 in FIG. The fed ink ribbon 81 is wound on the winding spool 73 while being in contact with the thermal print head 32. In this case, the rotation of the winding drive shaft motor 41 is detected by the motor encoder unit 47, and the winding speed of the ink ribbon 81 is reduced based on the detection signal of the motor encoder unit 47.
The take-up shaft drive motor 41 is torque-controlled by the motor drive control unit 104 so as to have a speed corresponding to the amount of movement.
In a state where the reverse rotation detection signal is given from the main encoder unit 24, no drive pulse is output to the winding shaft drive motor 41, and the winding of the ink ribbon 81 is not performed.

A delimiter address storage unit 116 and a matching circuit 117 are connected to an address bus from the address counter 111 to the image data memory 114. When the end key 91 in FIG. 1 is depressed for each reading scan by the scanning movement of the apparatus main body 1, the delimiter address storage unit 116 stores the writing address of the image data in the image data memory 114 at that time. For example, when a division scan by the end key 91 is performed for each of a plurality of read scans, a data write address corresponding to the division position is sequentially stored each time. In the print mode PR, the matching circuit 117 detects a match between the data read address for the image data memory 114, which is sequentially counted up, and the break address stored in advance in the break address storage unit 116. The coincidence detection signal is output to control section 101 and timing signal generation section 102. In this case, the control unit 101 stops outputting the print operation command P. Here, in the delimiter address storage unit 116,
The break address for each reading scan is controlled by the control unit 101 by the scanning of the search key 92 in FIG.
The delimiter address is given to the matching circuit 117 in accordance with the number of times the search key 92 has been operated, and the read start address of the delimiter data is given to the address counter 111 via the control unit 101. .

FIG. 10 is a timing signal generation circuit 102 shown in FIG.
First, when a read operation command R is given from the control unit 101, the main encoder unit
The counter CT starts the count operation in synchronization with the encoder pulse from 24, and the read timing signal generation circuit 102a and the serial / parallel signal generation circuit 102b transmit the read timing signal A and the serial / parallel signal to the A / D converter 109, respectively. A serial / parallel conversion signal B for the conversion unit 110 is generated. Here, the counter CT is
As shown in FIG. 11, the reading position r on the lower surface side of the apparatus main body 1
The counter carry is generated by counting the encoder pulse of the movement amount corresponding to the distance _l1 from the end to the traveling direction end, that is, the reading position r is equal to the distance _l1.
The clock pulse C for the address counter 111 is generated from the address counter timing signal generation circuit 102c from the point when the data is moved.

On the other hand, when a print operation command P is given from the control unit 101, a print timing signal is generated to the thermal head drive circuit 115 in synchronization with an encoder pulse from the main encoder unit 24.

Next, the operation of the compact copying apparatus having the above configuration will be described. When reading information such as characters and images recorded on a document, first, the mode switch 6 is switched from the OFF position to the reading mode switching position R. When the mode switch 6 is switched to the reading mode switching position R, the power is turned on and the control unit 101 enters the reading mode. At this time, the control unit 101 turns on the power-on display LED 7a of the LED unit 107 to indicate that the power is turned on, and transmits the operation command R to the timing signal generation unit.
Give to 102. At this time, the cam groove engaging pin 2 shown in FIG.
2 moves to the starting end of the upper horizontal groove 21b of the cam groove 21, the auxiliary roller unit 18 is lowered, and the auxiliary paper contact rollers 18a, 18b
Project below the main paper contact rollers 14a, 14b. Then, in this state, the user turns on the operation start switch 2 provided on the front surface of the apparatus main body 1 as shown in FIG. 7, and sets the apparatus main body 1 to the main paper contact rollers 14a, 14b and the auxiliary paper contact roller. 18a and 18b are placed in contact with the original a surface. At this time,
For example, as shown in FIG. 11, when it is desired to read only "BC" in the first scan of the image data "A to N" on the original a surface, the right side of the apparatus main body 1 is set in the reading range. Align to the left edge. As described above, when the apparatus main body 1 is placed on the document a, the paper surface detection switch 17 comes into contact with the document a and is turned on,
When both the paper surface detection switch 17 and the operation start switch 2 are turned on, the control unit 101 enters a reading operation state and the LED array 16 is turned on. The same applies to the case of performing printing described later. In this case as well, the control unit 101 includes the paper surface detection switch 17 and the operation start switch 2.
When both are turned on, the printer is in the printing operation state. Thereafter, the original a
When the scanning movement is manually performed forward (in the front direction of the apparatus main body 1) along the surface, the projection light from the LED array 16 irradiates the original a surface, and the reflected light is one-dimensionally transmitted through the imaging lens 60. The light enters the image sensor 57. On the other hand, the rotating disk 26 of the main encoder unit 24 is rotated by the rotation of the second paper contact roller 14b among the paper contact rollers that rotate in accordance with the movement of the apparatus main body 1 in contact with the original a surface. This rotating disk 26
As a result, a pulse signal corresponding to the movement of the apparatus main body 1 is output from the rotation amount detector 27. That is, the pulse signal output from the rotation amount detector 27 becomes the output of the main encoder unit 24 in FIG.
Control unit 101, timing signal generation unit 102, speed detection unit 103, motor drive control unit 104
Sent to In this case, the main encoder unit 24 outputs a normal rotation detection signal to the control unit 101, the timing signal generation unit 102, and the motor drive control unit 104.

On the other hand, when a read operation command R is given from the control unit 101, the timing signal generation unit 102 generates a CCD exposure timing signal of a fixed period, gives it to the one-dimensional image sensor 57, and moves the CCD exposure timing signal given from the main encoder unit 24. A read timing signal A and a serial / parallel conversion signal B are generated in accordance with the amount detection signal, and the A / D converter 109
And the serial / parallel converter 110. Here, the timing signal generator 102 shown in FIG.
Generates a clock pulse C from the time when the encoder pulse corresponding to the distance l ₁ in FIG. 11 is counted, and generates the address counter 111 and the read width memory address controller 1.
Output to 12.

Thus, the one-dimensional image sensor 57 outputs a signal corresponding to the light reflected from the surface of the document a, that is, an image signal, in synchronization with the CCD exposure timing signal from the timing signal generator 102. The output signal of the one-dimensional image sensor 57 is amplified by the amplifier 108 and sent to the A / D converter 109. The A / D converter 109 converts the image signal sent via the amplifier 108 into a serial digital signal in synchronization with the read timing signal A from the timing signal generator 102, and converts the image signal into a serial / parallel converter 110. Output to
The serial / parallel converter 110 converts the serial input signal into parallel image data, for example, every 8 bits in synchronization with the serial / parallel conversion signal B sent from the timing signal generator 102, and sends the data to the data selector 113. Output. When the reading mode is designated, the data selector 113 selects the select D from the control unit 101.
Is switched to the serial / parallel converter 110 side. Therefore, the image data output from the serial / parallel converter 110 is sent to the image data memory 114 via the data selector 113. The write address of the image data memory 114 is specified by the count output of the address counter 111. This address counter 111
Is the clock pulse C from the timing signal generator 102
Sequentially increments the digit address by “+1”, and specifies the address of the image data memory 114. When one row of image data is written to the image data memory 114, the timing signal generator 102 stops generating the timing signal, and the next movement amount detection signal is sent from the main encoder unit 24. Until it is in a standby state. In this case, when the reading width of the document a is designated in advance by the reading width designation switch 5, the address number data converted into the designated width is set in the reading width memory address control unit 112. Then, the address counter 111 matches the write address for one row with the address number data corresponding to the designated read width, and repeatedly designates the address to the image data memory 114. That is, of the image data read by the image sensor 57, only the image data from the zero point of the width scale in FIG. 1 to the scale including the operation knob 5a is written into the image data memory 114. Become.

Here, since the clock pulse C is not given to the address counter 111 until the apparatus main body 1 moves the distance l ₁ , the image data read by the image sensor 57 until then is written to the image data memory 114. Disabled. Thereafter, the same operation is repeated, and the image data read in the X direction from the right side position at the initial setting position of the apparatus main body 1 on the original a is sequentially written into the image data memory 114.

Thereafter, the image data “BC” on the original a side is moved to the apparatus main body 1.
Is moved so that its left side position is aligned with the right end of the reading range, and the operation start switch 2 is turned off.
Is turned off, a predetermined reading end processing operation is started.

FIG. 12 is a flowchart showing the read end processing operation. In the state where the operation start command signal is given from each of the switches 2 and 17, the read operation command R is continuously output from the control unit 101 (step S1). S2) When the operation start command signal is no longer given, the output of the read operation command R from the control unit 101 is stopped (step S1 →
3). Then, the data selector 113 is switched to the control unit 101 side, and the control unit 101 outputs clear data to the image data memory 114, and at the same time, the address counter 111
Is supplied with a down-count control signal, and a down-count for a predetermined address is started (steps S4 to S7). Here, the predetermined address is a distance from the reading position r on the lower surface side of the apparatus main body 1 in FIG. 11 to an end position in the direction opposite to the reading progress direction, that is, a left position of the apparatus main body 1.
an address component corresponding to l _2, read image data corresponding from the left side surface of the apparatus main body 1 during the reading ends between the distance l ₂ will be erased from the image data memory 114. That is, the image data from the left side position to the reading position r in the reading final setting position of the apparatus main body 1 becomes invalid. Therefore, the range from the right side position at the start of the scanning movement of the apparatus main body 1 to the left side position at the end of the movement can be defined as the read range of the image data for the document a.

Here, as shown in FIG. 11, when the image data “BC” is read by the first scan and the image data “GHI” and “LMN” are read separately by the second and third scans Then, the end scanning is performed by the end key 91 on the read end sheet. FIG. 13 shows the read data separation processing by the end key 91. When the end key 91 is operated every time the above image data "BC", "GHI", and "LMN" are read, an address counter is provided at each time. The write end address of the read image data set in 111 is stored in the delimiter address storage unit 116 (step A1).
In this case, each time the end key 91 is operated, the address section 118 is incremented, and the write address to the break address storage section 116 is updated.

Here, when reading the document a, since the auxiliary contact paper rollers 18a, 18b are projected below the main paper contact rollers 14a, 14b, the apparatus main body 1 is as shown in FIG. Then, the scanning movement is performed with the posture slightly inclined forward. Therefore, the print head 32 protruding from the lower surface of the apparatus
The leading end of the ink ribbon 81 and the ink ribbon 81 thereunder do not come into sliding contact with the surface a of the original, and the wear of the print head 32 and the ink ribbon 81
Of the original a is prevented.

Note that the speed detecting unit 103 detects the moving speed of the apparatus main body 1 based on the pulse signal from the main encoder unit 24, and if the moving speed is too fast, the LED unit 107
, The speed warning LED 7c is turned on to warn the user. This is the same at the time of printing. Further, during the reading, the image data memory 114 is not read.
When the remaining memory capacity is low, the remaining memory display LE 7b is turned on to notify that the remaining memory capacity is low.

Next, an operation when the image data read from the document a as described above is printed out will be described. To print out the image data, the mode changeover switch 6 is switched to the print mode changeover position P. When the mode changeover switch 6 is switched to the print mode changeover position P, the control unit 101 enters the print mode, and the data selector 113 is switched by the select signal D.
Is switched to the control unit 101 side. At this time, the cam groove engaging pin 22
Moves to the lower horizontal groove portion 21a of the cam groove 21, the auxiliary roller unit 18 is raised, and the auxiliary paper contact rollers 18a, 18b have the same protruding level as the main paper contact rollers 14a, 14b. In this state, as shown in FIG. 6, the user places the copying machine main body 1 with the contact rollers 14a, 14b and 18a, 18b in contact with the surface of the external recording paper b such as a notebook. As described above, when the apparatus main body 1 is placed on the recording paper b, the paper surface detection switch 17 comes into contact with the recording paper b and is turned on, and the print head 32 comes into contact with the recording paper b via the ink ribbon 81. . In this case, the print head 32
Rises to the recording paper contact level of each of the paper contact rollers 14a, 14b and 18a, 18b while compressing the pressing spring 33 by contact with the recording paper b, and presses against the recording paper b surface by the repulsive force of the pressing spring 33. Is done. Thereafter, when the operation start switch 2 is turned on and the copying apparatus main body 1 is scanned forward along the surface of the recording paper b, the respective paper contact rollers rotate with the movement of the apparatus main body 1, and the The rotation of the two main contact rollers 14b is transmitted to the line disk 26 via the rotation transmission belt 28. With the rotation of the line disk 26, a movement amount detection signal corresponding to the movement speed of the apparatus main body 1 is read from the main encoder unit 24 in the same manner as in the above reading.

When the main encoder unit 24 outputs a moving amount detection signal and a normal rotation detection signal by starting the forward movement of the apparatus main body 1, the motor drive control unit 104 drives the winding shaft drive motor 41. As a result, the ink ribbon take-up shaft 40 is driven to rotate, and the take-up spool 73 of the ink ribbon cassette 70 is rotated in the take-up direction.
The ink ribbon 81 fed from the 74 passes through the heat generating portion of the thermal print head 32 and is wound on the winding spool 73. In this case, the rotation of the winding shaft drive motor 41 is detected by the motor encoder unit 47, and the motor drive control unit 10
4 controls the torque of the winding shaft drive motor 41 based on the detection signal given from the motor encoder unit 47 so that the winding speed of the ink ribbon 81 matches the moving amount of the apparatus main body 1, that is, the printing speed. This motor torque control is performed by the motor drive control unit 104 every time the winding shaft drive motor 41 makes one rotation.
Pulse signal period from 7 and main encoder unit 2
The number of encoder pulses supplied from the main encoder unit 24 during one rotation of the motor 41 is larger than a predetermined value (the moving speed of the apparatus body 1). Is higher than the ribbon take-up speed, the motor drive pulse width is increased to increase the ribbon take-up speed, and when the number of encoder pulses is smaller than a predetermined value (the moving speed of the apparatus body 1 is lower than the predetermined value). If the speed is lower than the ribbon winding speed), the motor driving and the pulse width are shortened to reduce the ribbon winding speed. The same applies to the case where the ribbon winding diameter of the winding side spool 73 increases and the load applied to the motor 41 increases, and the same applies to the case where the ribbon winding speed decreases due to the increase in the load applied to the motor 41. Since the number of encoder pulses during one rotation of the motor 41 becomes larger than a predetermined value, the torque of the motor 41 is automatically increased at this time, and the ribbon winding speed is increased.

On the other hand, the control unit 101 includes the main encoder unit 2
In response to the movement amount detection signal sent from 4, a one-line print command is output to the timing signal generator 102, and the timing signal generator 102 outputs a print timing signal to the thermal head drive circuit 115. The control unit 101
Sequentially designates the row and digit addresses of the image data memory 114 in accordance with the movement amount detection signal from the main encoder unit 24, reads out the image data stored in the image data memory 114 via the data selector 113, and The data is output to the head drive circuit 115 for each row. Here, for example, if the search key 92 is operated once beforehand after setting the print mode PR, the address counter 111
Are initialized, and the image data in the image data memory 114 is the first data, that is, the first data read by the first scan.
The data is read from the beginning of the read data "BC" in FIG. When the search key 92 is operated twice, the data "GHI" read by the second scan is read.
However, in the case of three times, "LMN" by the third operation is read from the head. Further, the control unit 101
When a one-line print command is given, the thermal print head 32 is energized based on the number of black characters of print data, the head temperature from the temperature sensor 106, the voltage detection signal of the power supply voltage detector, the adjustment value of the print density adjustment knob 8, and the like. The time is set, and the image data read from the image data memory 114 is output to the thermal head drive circuit 115. This thermal head drive circuit 1
Reference numeral 15 drives the thermal print head 32 according to control data from the control unit 101 and a timing signal from the timing signal generation unit 102. By driving the thermal print head 32, the image data is transferred to the recording paper b via the ink ribbon 81.
Transferred to the top. In this case, with the movement of the apparatus main body 1, the ink ribbon take-up shaft 40 is driven to rotate by the take-up shaft drive motor 41, and the unused portion of the ink ribbon 81 is sent out from the supply side spool 74. Used part after printing by spool on take-up side
It is wound up sequentially in 73. By moving the copying apparatus main body 1 as described above, the image data stored in the image data memory 114 is sequentially printed on the recording paper b.

Next, a description will be given of a data designation print operation using the search key 92 in the case where a delimiter process is performed by the end key 91 in each read scan in the read mode.

FIG. 14 is a flowchart showing the data designation print operation. When the search key 92 is operated after the print mode PR is set, it is determined whether or not the number of operations is the first time (step B1, B2). Here, if the first operation of the search key 92 determines “YES” in step B2, the address counter 111 and the address section 118 are initialized, and the read address for the image data memory 114 is set to the head address. Along with
The first break address stored in the break address storage unit 116, that is, the last address in the image data memory 114 of the image data "BC" read by the first scan is set in the matching circuit 117 (steps B3 to B5). Here, when an encoder pulse is output from the main encoder unit 24, data (in this case, “BC”) in the image data memory 114 is read in accordance with the read address indicated by the address counter 111, and the thermal head drive circuit 115 (Steps B6 and B7).
During the printing process in step B7, the read address of the address counter 111 for the image data memory 14 is sequentially transferred to the matching circuit 117. Here, the matching circuit 117 sets a preset break address (in this case, When the read address matches the final address of the image data “BC” obtained by the first read scan, the control unit 101 stops outputting the print operation command P (steps B8 and B9). On the other hand, if no match is detected in the match circuit 117, or if the operation start switch 2 is not turned off, the read and print processing of the image data according to the output of the encoder pulse is sequentially repeated (steps B6 to B10). That is, when the print processing is performed by scanning the search key 92 once, only the image data “BC” read by the first reading scan is printed, as shown in the upper part of FIG. The image data "GHI" is not continuously printed even after reading by the second reading scan.

On the other hand, the search key 92
Is operated twice, through the above steps B1 to B5, further proceeds to steps B1, B2 → B11, and the address data obtained by adding (+1) to the first delimiter address stored in the delimiter address storage unit 116, that is, The head address in the image data memory 114 of the image data “GHI” read by the second reading scan is set in the address counter 111.
Then, the address section 118 is incremented, and the second break address in the break address storage section 116, that is, the last address of the image data "GHI" in the image data memory 114 is specified (step B12). Then, the second break address specified by the address section 118 is read from the break address storage section 116 and set in the coincidence circuit 117 (step B13). Thereafter, when an encoder pulse is output from the main encoder unit 24, the same processing as in steps B6 to B10 is performed, and
As shown in the lower part of the figure, only the image data “GHI” read by the second reading scan is printed.

Further, when the search key 92 is operated three times, only the image data “LMN” read by the third reading operation is printed in the same manner as described above.

The image data to be printed on the recording paper b is printed with the same width as the reading width from the document a. However, if the enlarged print is designated by the enlarged print designation key 3 in FIG. Printing can be performed by enlarging the width to a predetermined ratio. If the reset / clear key 4 is pressed after printing is completed, the same image data can be repeatedly printed. Here, since the small-sized copying machine presses the print head 32 into contact with the recording paper b with the spring force of the pressing spring 33, the print head 32 always makes contact with the recording paper b at a constant pressure to perform printing. Can be made. Further, since the print head 32 is provided so as to be rotatable and rotatable, even when the apparatus main body 1 is tilted left and right during the scanning movement, the print head 32 is rolled to the opposite side by the tilt angle of the apparatus main body 1 and always records flat. Since the print image comes into contact with the surface of the paper b, the print image does not fade.

Therefore, according to the compact copying apparatus having the above-described configuration, not only can the image data on the document a be read and printed on the surface of the recording paper b by scanning and moving the apparatus main body 1, but it is also possible to arbitrarily separate the data during the scanning. Image data can be selectively printed for each delimited image data. In other words, it is possible to designate and print only the image data of the necessary delimiter portion among the image data read and stored by the plurality of reading scans.

In the above-described embodiment, the print output portion by the thermal print head 32 is hidden by the apparatus main body 1 so that it is difficult to look directly. However, since only the required image data can be printed, the image data memory 114 has There is no danger that the next image data stored continuously will be printed subsequently.

[Effects of the Invention] As described above, according to the present invention, a housing, reading means provided in the housing for reading image information on the document in accordance with movement of the housing, and the reading means Delimiter for arbitrarily dividing a read area when reading image information on a document, and storage means for recording image information of a plurality of read areas on the document read by the reader, separated by the delimiter Designation means for designating only image information of a required reading area among the image information of the plurality of reading areas stored in the storage means, and output for outputting image information of the reading area designated by the designation means With the configuration including the control means, it is possible to print out only necessary image data without continuously printing the image data read separately by scanning a plurality of times. It is possible to provide an image data processing device that can be used.
