8, and is attached to the front case 1a so as to be openable and closable. Further, a hook member 69a for locking the opening/closing lid 1d in a closed state is provided on the inner surface of the other side edge of the opening/closing lid 1d, and a hook member 69a is provided on the side edge of the cassette loading port 1C on the rear case 1b side. A lock protrusion 69b for engaging the hook member 69a is provided in a protruding manner. The hook member 69a is moved up and down by the sliding operation of a lock knob (not shown) provided on the outer surface of the opening/closing lid 1d so as to be slidable in the vertical direction. When slid, the hook member 69a engages with the lock protrusion 69b from above, opening/closing 11.
When d is locked and the lock knob is slid upward, the hook member 69a is disengaged above the lock protrusion 69b, and the opening/closing mechanism 111d is unlocked.

Then, the ink tape cassette 70 is inserted and loaded into the apparatus main body 1 through the cassette loading port 1C by opening the opening/closing lid 1d. This ink tape cassette 70 is constructed by aligning the cutout 72 with the print head unit 30 in the apparatus main body 1 from the side surface where the cutout 72 is formed, and aligning the cutout 72 with the exposed ends of the take-up spool 73 and the supply spool 74. The ink tape cassette 70 is inserted facing the ink tape take-up shaft 40 and the supply side spool engagement shaft 50 in the apparatus main body 1. When the ink tape cassette 70 is inserted into the apparatus main body 1, the ink tape cassette 70 shown in FIGS. As shown in the print head unit 3
0 enters into the cassette case 71 through the notch 72, and the tip of the print head 32 comes to face the ink tape part exposed in the open part at the lower end of the cassette from above, and the ink tape winding shaft 40 and the supply side spool engagement shaft 50 fit into and engage with the take-up side spool 73 and the supply side spool 74 of the ink tape cassette 70, respectively. In this case, the supply side spool retaining shaft 5o, which is pushed forward in the distal direction by the brake spring 52, remains in the pushed state until the supply side spool 74 is completely fitted. When the push step 83 in the supply spool 74 comes into contact with the shaft end of the supply spool engagement shaft 50, the supply spool engagement shaft 50 is inserted into the ink tape cassette 70 to the final loading position. While compressing the brake spring 52, it is pushed toward the proximal end as shown in FIG.

Therefore, when the ink tape cassette 70 is loaded into the main body 1 of the apparatus, the brake member 53 is strongly pressed against the inner surface of the shaft end of the supply side spool engagement shaft 50 by the repulsive force of the brake spring 52. The side spool engagement shaft 50 is braked from its rotation to apply pack tension to the ink tape 81 being fed out from the supply side spool 74 of the ink tape cassette 70 .

The ink tape cassette 70 loaded into the main body 1 of the apparatus can be moved to the loading position by closing the opening/closing lid 1d of the cassette loading port 1C and locking the opening/closing lid 1d. is maintained. Further, loading the ink tape cassette 70 into the apparatus main body 1 can be carried out after switching the operating knob 6a of the mode changeover switch 6 to the eject position E and then pulling down the auxiliary roller unit 18. , auxiliary paper contact roller 18a on the cassette loading 01C side of the apparatus main body 1
will not interfere with loading the cassette.

This also applies when the ink tape cassette 70 is removed from the apparatus main body 1. Above auxiliary roller unit 1
8 is pulled down by manually pulling the roller shaft 20 downward, and by pressing the operation knob 6 of the mode changeover switch 6.
When the switch a is switched to the eject position E, the cam groove engagement pin 22 that moves together with the operating knob 6a comes under the vertical groove 21d of the cam groove 21 of the elevating plate 19, so that the auxiliary roller unit 18 can be pulled down. .

Further, the ink tape cassette 70 is removed from the inside of the apparatus main body 1 by opening the open rfll 11d.
In this case, since the supply side spool engaging shaft 50 that is fitted and engaged with the supply side spool 74 of the ink tape cassette 70 is pressed in the distal direction by the brake spring 52, when the opening/closing lid 1d is opened, the brake spring The spring force of 52 pushes the ink tape cassette 70 together with the supply side spool engagement shaft 50 toward the cassette loading port 1C, and the sides of the ink tape cassette 70 protrude outside from the cassette loading port 1C. can be easily extracted.

FIG. 11 schematically shows the configuration of the above-mentioned small-sized copying machine, which includes the control unit 12 and L
A front case block A incorporating the ED array 16, a front case block B incorporating the auxiliary roller unit 18, a main encoder unit 24, a print head unit 30, an ink tape winding unit 39, a reading unit 54, and a power supply. It consists of three blocks including a center block C incorporating a unit 65, and the LED array 16 of the front case block A and each unit of the center block C 24.30°47.54 and 6
5 are respectively connected to the control unit 12 of the front case block A by flexible connectors 90 such as lead wires or flat cables.

Next, the configuration of an electronic circuit formed around the circuit board 12a of the control unit 12 shown in FIG. 1 will be explained with reference to FIG. 12. Main encoder unit 2
4 is a rotating disk 26 and a rotation amount detector 27 as described above.
It outputs a pulse signal corresponding to the amount of movement of the device main body 1, that is, a movement amount detection signal, and a forward/reverse rotation detection signal of the rotating disk 26 corresponding to the direction of movement of the device main body 1. do. This main encoder unit 24
The movement amount detection signal output from the control unit 101,'!
The signal is then sent to the timing signal generation section 102, speed detection section 103, and motor drive til11 section 104.

Further, the forward rotation/reverse rotation detection signal is sent to the control section 101, the timing signal generation section 102, and the motor drive control section 104. The control unit 101 includes the operation start switch 2 shown in FIGS. 2 and 3, the enlarged print designation key 3, the reset/clear key 4, the reading width designation switch 5, the mode changeover switch 6, the print density adjustment knob 8, etc. An operation signal is given from the key and switch 105, and a temperature detection signal is given from a temperature sensor 106 that detects the temperature of the thermal print head 32 and the temperature of the recording paper sheet. Further, the control unit 101 (not shown) is provided with an internal voltage detector. Then, the control section 101 controls the lighting of the LED section 1 section 07 for the 1ttaON display LED 7a, the remaining memory capacity display LED 7b1, the speed warning LED 7C, and controls the other sections in response to the operation signals from the keys and switches 107. At the same time, operation commands R and P are given to the timing signal generator 102 according to the reading mode or print mode specified by the mode changeover switch 6. In this case, the control unit 101 provides the timing signal generating unit 102 with an operation command R1 in the read mode and an operation command P in the print mode.

When the timing signal generating section 102 is given the operation command R from the control section 101, it generates a COD exposure timing signal of a constant period, and also generates a predetermined COD exposure timing signal in synchronization with the movement amount detection signal given from the main encoder unit 24. Various timing signals such as a number of reading timing signals A1, a serial/parallel conversion signal B1, and a clock pulse C are generated. Further, when the operation command P is given from the control section 101, the timing signal generating section 102 generates a print timing signal in synchronization with the movement amount detection signal only when the normal rotation detection signal is given from the main encoder unit 24. occurs. The COD exposure timing signal outputted from the timing signal generating section 102 is outputted to the one-dimensional image sensor 57, and the reading timing signal A is outputted from the one-dimensional image sensor 57.
/D converter 109 receives serial/parallel conversion signal B, and serial/parallel converter 110 receives clock pulse C.
are sent to the address counter 111 and the reading width memory address control section 112, respectively.

The -dimensional image sensor 57 reads the reflected light from the document a in synchronization with the COD exposure timing signal, and outputs it to the A/D converter 109 via the amplifier 108. This A
The /D converter 109 reads the input signal and converts it into a timing signal A.
converts the input signal into a black and white binary signal and outputs it to the serial/parallel converter 110. This serial/parallel converter 110 converts the input signal into a serial/parallel converted signal B.
For example, every 8 bits are converted into parallel signals and output to the image data memory 114 via the data selector 113. Further, the data selector 113 has its data line connected to the control section 101, and
Either the serial/parallel converter 110 or the controller 101 is selected by the select signal from the serial/parallel converter 110. The write address (row and column address) of the image data memory 114 is indicated by the reading width memory address control unit 112 and designated by the address counter 111. Here, the reading width memory address control section 112 includes:
The reading width address data based on the scanning of the reading width designating switch 5 in FIG. 3 is given from the control section 101, and the write designated address by the address counter 11 is counted up by the corresponding address number during designated reading.

That is, only the image data between the 0 point on the width scale drawn along the reading width designation switch 5 and the scale set by the operation knob 5a is written and stored in the image data memory 114. Further, the read address of the image data memory 114 is also given by the control unit 101 via the address counter 111, but in this case as well, based on the number of reading width addresses set in the reading width memory address control unit 112, the printing-direction is The read address of is specified. Here, after the start of the reading scanning movement, the timing signal generating circuit 102 outputs an address counter if a main encoder pulse corresponding to the distance from the reading position on the bottom side of the apparatus main body 1 to the end in the direction of movement is not applied. Since no clock pulse is generated for the image data memory 111, the read data is not actually written into the image data memory 114 until the read position advances to the end position in the reading direction at the initial installation position of the apparatus main body 1.

Furthermore, when reading the image data is finished, the image data written in the image data memory 114 is
The address corresponding to the distance from the reading position on the bottom side to the end in the opposite direction of travel is cleared, so in reality,
Image data is only read up to the end in the opposite reading direction at the final installed position of the main body 1 of the apparatus. In other words, in the reading state of the main body 1 shown in FIG. Become.

When the reading of the document is completed and the mode is switched to the print mode, the control section 101 outputs the operation command P to the timing signal generation section 102 as described above, and also changes the amount of movement from the main encoder unit 24. The data stored in the image data memory 114 is sequentially read out via the data selector 113 in accordance with the detection signal. When the control unit 101 reads the image data from the image data memory 114, it sets the energization time 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, It is output to the thermal head drive circuit 115 as print data. When the thermal head drive circuit 115 receives print data from the control section 101, it drives the thermal print head 32 in synchronization with the timing signal from the timing signal generation section 102.

Here, the motor drive control section 104 provides 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, so that the ink tape shown in FIG. The ink tape 81 fed out from the supply spool 74 of the cassette 70 is wound onto the take-up spool 73 while contacting the thermal print head 32 . In this case, the rotation of the take-up shaft drive motor 41 is detected by the motor encoder unit 47, and the take-up speed of the ink tape 81 is adjusted to a speed that matches the amount of movement of the main body 1 based on the detection signal of the motor encoder unit 47. The torque of the winding shaft drive motor 41 is controlled by the motor drive control section 104 so that the winding shaft drive motor 41 is rotated. Note that in a state in which the reverse rotation detection signal is applied from the main encoder unit 24, no drive pulse is output to the winding shaft drive motor 41, and winding of the ink chip 181 is not performed.

Figure 13 shows the timing signal generation circuit 1 in Figure 12.
02, first, when a read operation command R is given from the control unit 101, the counter CT starts counting operation in synchronization with the encoder pulse from the main encoder unit 24, and at the same time, a read timing signal is generated. The circuit 102a and the serial/parallel signal generating circuit 102b generate a read timing signal A for the A/D converter 109 and a serial/parallel conversion signal B for the serial/parallel converter 110, respectively. Here, the counter CT generates a counter carry by counting encoder pulses of a movement amount corresponding to a distance ℃1 from the reading position r on the lower surface side of the device main body 1 to the end in the direction of movement (16th (see figure (A)),
In other words, a clock pulse for the address counter 111 is generated from the address counter timing signal generation circuit 102C from the time when the reading position r has moved a distance 21.

On the other hand, when a print operation command P is given from the control section 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, FIGS. 14(A) and 14(B) show the structure of the paper surface detection switch 17 shown in FIGS. 6 and 7, respectively, and the operating bin 17a is equipped with a small paper contact roller at its tip. There is. When the main body 1 of the apparatus shown in FIG. 14(A) is not placed on the original Ia or the recording paper, the operating bottle 17a protrudes from the lower surface of the front case 1a due to the spring force of the spring 17b, and the contacts 17c and 17d do not come into contact with each other. . On the other hand, when the main body 1 of the apparatus shown in FIG.
It is pushed in the direction shown by arrow 1 against the spring force b, and contacts 17c and 17d come into contact. That is, by placing the apparatus main body 1 on the original 8 side or the recording paper side, a 6 "H" (high) level signal is sent from the paper surface detection switch 17 to the control section 1.
Output to 01.

FIG. 15 shows a combination circuit of the paper surface detection switch 17 and the operation start switch 2, and each switch 2 and 1
The switching signal @ Gt from 7 is input to the AND gate AND4 and the NOR gate NOR, respectively, and the output of the AND gate AND4 is given to the set terminal S of the flip 70-tube FF, and the output of the NOR gate NOR is given to the reset terminal R of the flip-flop FF. It will be done. Then, the Q output of the flip 70-tube FF is given to the control section 101 as an operation start command signal. That is, both the operation start switch 2 and the paper surface detection switch 17 are turned on to output the operation start command signal, and both are turned off to stop the output. Therefore, reliable reading and printing operations can be performed according to the user's intention and the installation state of the apparatus main body 1 with respect to the paper surface.

Next, the operation of the compact copying apparatus having the above configuration will be explained. When reading information such as characters and images recorded on a document, first, the mode changeover switch 6 is switched from the OFF position to the reading mode changeover position R. When the mode changeover switch 6 is switched to the read mode changeover position R, the power is turned on and the control unit 101 is placed in the read mode. At this time, the control unit 101 controls the LED
Turn on the power ON display LED 7a in part 1 part 07,
In addition to displaying that the power is turned on, an operation command R is given to the timing signal generating section 102.

At this time, the cam groove engaging pin 22 in FIG.
The auxiliary roller unit 18 is moved to the starting end of the upper horizontal groove portion 21b of 1, and the auxiliary roller unit 18 is lowered.
b is the main contact sheet 0-ra 14a.

It protrudes lower than 14b. However, the user
In this state, as shown in FIG. 7, turn on the operation start switch 2 provided on the front of the device main body 1, and
, the main contact roller 14a.

14b and auxiliary paper contact rollers 18a and 18b are placed in contact with side A of the document. At this time, for example, as shown in FIG. 16(A), if it is desired to read only rBcJ of the image data rABcDJ on page 8 of the original, the right side of the main body 1 of the apparatus is aligned with the left end of the reading range. In this way, when the main body 1 of the apparatus is placed on the document a, the paper surface detection switch 17
When the paper surface detection switch 17 and the assistance start switch 2 are both turned on, the control unit 101 enters the reading operation state and the LED array 1 is turned on.
6 lights up. Note that this also applies to the case of printing, which will be described later.
When it is L, it is in the printing operation state. After this, the device body 1
When the scanner is placed on document a and is manually scanned forward (in the direction of the front of the apparatus main body 1) X along side A of the document, the projected light from the LED array 16 is irradiated onto side A of the document. , the reflected light enters the one-dimensional image sensor 57 via the imaging lens 60. On the other hand, among the contact rollers that contact side A of the document and rotate as the apparatus main body 1 moves, the rotation of the second contact roller 14b rotates the rotating disk 26 of the main encoder unit 24. This rotating disk 2
6, the rotation amount detector 27 outputs a pulse signal corresponding to the amount of movement of the apparatus main body 1. That is, the pulse signal output from the rotation amount detector 27 becomes the output of the main encoder unit 24 in FIG.
1. Timing signal generation section 102, speed detection section 103,
The signal is sent to the motor drive control section 104. In this case, the main encoder unit 24 outputs a normal rotation detection signal to the control section 101, the timing signal generation section 102, and the motor drive control section 104.

On the other hand, when the timing signal generation unit 102 receives the read operation command R from the control unit 101, the timing signal generation unit 102 generates a COD signal at a constant period.
Generates an exposure timing signal and sends the -dimensional image sensor 5
7 and generates a read timing signal A and a serial/parallel conversion signal B according to a movement amount detection signal given from the main encoder unit 24.
/D converter 109 and serial/parallel converter 110
Output to each. Here, the timing signal generating section 102 in FIG. 13 has a distance e in FIG.
A clock pulse C is generated from the time when encoder pulses corresponding to el (lt) are counted, and is output to the address counter 111 and the reading width memory address control section 112.

Thus, the above-mentioned -dimensional image sensor 57 outputs a signal corresponding to the reflected light from the surface of the original 8, that is, an image signal, in synchronization with the above-mentioned CCD exposure timing signal from the timing signal generating section 102. This -dimensional image sensor 57
The output signal is amplified by the amplifier 108 and sent to the A/D converter 109. The A/D converter 109 converts the uniform 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 it into a serial digital signal. Output to 110. This 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 811102, and converts the serial input signal into parallel image data, for example, every 8 bits. Output to.

When the read mode is designated, the data selector 113 is switched to the serial/parallel converter 11o side by select D from the controller 101. 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 this m-image data memory 114 is determined by the address counter 11.
Specified by a count output of 1. The address counter 111 has its digit addresses sequentially incremented by "+1" by the clock pulse C from the timing signal generator 102, and specifies the address of the image data memory 114. and,
The timing signal generation section 102 includes the image data memory 11
When one line of image data is written to 4, the generation of the timing signal is stopped and the main encoder unit 24 enters a standby state until the next movement detection signal is sent.In this case, the reading width Select the document a in advance using the designation switch 5.
When the reading width is specified, the address number data converted during the specification is set in the reading width memory address control section 112. Then, the address counter 111 matches the address number data for one line with the address number data corresponding to the specified reading width, and repeatedly specifies the address for the image data memory 114. In other words, the image sensor 57
Of the image data read in, only the image data between the 0 point of the width scale and the scale of the operation knob 5a in FIG. 2 is written into the image data memory 114.

Here, since the clock pulse C is not given to the address counter 111 until the device body 1 moves the distance C1, the image data read by the image sensor 57 is not written to the image data memory 114 until then. become invalid. Thereafter, similar operations are repeated, and image data read in the X direction from the right side position of the initial installation position of the apparatus main body 1 on the original 8 side is sequentially written into the image data memory 114.

After this, the image data of the 8th side of the original "BcJ" is transferred to the device main body 1
, align the left side position with the right edge of the area to be read fIi, turn off the operation start switch 2, and further move the main body 1 away from the document a and turn off the paper surface detection switch 17. The reading end processing operation is started.

FIG. 17 is a flowchart showing the above-mentioned reading end processing operation, and in a state where the operation start command signal is applied from each switch 2.17, the reading operation command R is continuously output from the #1111 section 101 (step 81 .3
2) When the operation start command signal is no longer applied, the output of the reading operation command R from the control section 101 is stopped (step S1→83). And data selector 11
3 is switched to the control unit 101 side, and clear data is output from the control unit 101 to the image data memory 114. At the same time, a down-count control signal is given to the address counter 111, and a down-count by a predetermined address is started. (Steps 84 to S7). Here, the above-mentioned predetermined address is the distance from the bottom side reading position r of the 5i11 main body 1 in FIG. The read image data that corresponds to the address corresponding to .degree. That is, the image data from the left side position of the final reading installation position of the apparatus main body 1 to the reading position @r becomes invalid. Therefore, the range from the right side position at the start of the scanning movement of the apparatus body 1 to the left side position at the end of the movement can be defined as the reading range of the image data for the document a, and the desired two-way data can be easily and accurately read. Becomes readable.

Here, when reading the document a, the auxiliary contact rollers 18a and 18b are replaced by the main contact rollers 14a and 14b.
Since the device body 1 is made to protrude further downward than the seventh
As shown in the figure, the camera is scanned in a slightly tilted position forward. Therefore, the tip of the print head 32 protruding from the lower surface of the apparatus and the ink chip 781 therebelow do not come into sliding contact with the surface of the original 8, and wear of the print head 32 and staining of the surface of the document 8 by the ink chip 781 are prevented.

Note that the speed detection section 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, 160
The speed a warning LED 7c in the section 107 is lit, and a warning is given to the user. This also applies during printing. Further, when the remaining memory capacity of the image data memory 114 decreases during the above reading, the remaining memory capacity display LED 7b is lit to notify that the remaining memory capacity is low.

Next, the operation when printing out the image data read from the document a as described above will be explained.

When printing out image data, the mode changeover switch 6 is switched to the print mode changeover position P. When this mode changeover switch 6 is switched to the print mode changeover position P, the control unit 101 becomes the print mode, and the data selector 11 is activated by the selection signal.
3 to the control unit 101 side. At this time, the cam groove engagement pin 22 moves to the lower horizontal groove 21a of the cam groove 21, the auxiliary roller unit 18 is raised, and the auxiliary contact roller 1
8a and 18b are at the same protrusion level as the main contact rollers 14a and 14b. In this state, the user, as shown in FIG. 6, moves the main body 1 of the copying apparatus to each of the paper rollers 14a, 14b, and 18a.

18b is placed in contact with the surface of external recording paper such as a notebook.

In this way, when the device main body 1 is placed on the recording paper, 1iI
The I side detection switch 17 comes into contact with the recording surface MB and turns ON, and the print head 32 comes into contact with the recording paper surface via the ink tape 81. In this case, the print head 32 compresses the pressure spring 33 by contact with the recording paper and rises to the recording paper contact level of each paper contact roller 14a, 14b and 18a, 18b (7), and the repulsive force of the pressure spring 33 is pressed into contact with the surface of the recording paper. After this, when the operation start switch 2 is turned on, a print operation command P is output from the control unit 101, and when the copying apparatus main body 1 is scanned forward along the surface of the recording paper, this apparatus main body 1 is moved. As a result, each of the contact rollers rotates, and the second main contact roller 1 rotates.
4b is transmitted to the rotating disk 26 via the rotation transmission belt 28.
transmitted to.

As the rotary disk 26 rotates, a movement detection signal corresponding to the movement speed of the apparatus main body 1 is extracted from the main encoder unit 24 in the same way as in the above-mentioned reading.

When the main encoder unit 24 outputs a movement amount detection signal and a forward rotation detection signal by starting the forward movement of the apparatus main body 1, the motor drive control section 104 drives the winding shaft drive motor 41. As a result, the ink tape winding shaft 4o is rotationally driven, the winding side spool 73 of the ink tape cassette 7o is rotated in the winding direction, and the ink chi 781 fed out from the supply side spool 74 hits the heat generating part of the thermal print head 32. The film is then wound onto the winding side spool 73. In this case, the rotation of the take-up shaft drive motor 41 is detected by the motor encoder unit 47, and the motor drive control section 104 determines the take-up speed of the ink chip 781 based on the detection signal given from the motor encoder unit 47. The torque of the take-up shaft drive motor 41 is controlled to match the moving amount, that is, the printing speed. This motor torque control is performed by comparing the pulse signal period from the motor encoder unit 47 and the number of encoder pulses from the main encoder unit 24 in the motor drive control section 104 every time the take-up shaft drive motor 41 rotates once. While the motor 41 rotates once, the main encoder unit 2
When the number of encoder pulses given from 4 is greater than a predetermined value (when the moving speed of the main body 1 of the apparatus is faster than the tape winding speed), the motor drive pulse width is increased to increase the tape winding speed. Furthermore, when the number of encoder pulses is less than a predetermined value (when the moving speed of the apparatus main body 1 is slower than the tape winding speed), the motor drive pulse width is shortened to reduce the tape winding speed. This also applies when the tape winding diameter of the winding side spool 73 increases and the load on the motor 41 increases, and when the tape winding speed slows down due to an increase in the load on the motor 41. Also, since the number of encoder pulses during one rotation of the motor 41 becomes greater than a predetermined value, the torque of the motor 41 is automatically increased at this time as well, and the tape winding speed is increased.

On the other hand, the control section 101 outputs a one-line print command to the timing signal generation section 102 in response to the movement amount detection signal sent from the main encoder unit 24, and this timing signal generation section 102 drives the thermal head. A print timing signal is output to the circuit 115. Further, the control unit 101 sequentially specifies 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, and selects the image data stored in the image data memory 114 from the data selector 113. The data is read out through the thermal head drive circuit 115 and output one row at a time. Furthermore, when the control unit 101 is given a one-line print command, it outputs the number of black characters in the print data, the head temperature S from the temperature sensor 106, the voltage detection signal from the source voltage detector, and the print n.
Thermal print head 3
2, and set the energization time for image data memory 114.
The image data read from the thermal head drive circuit 11
Output to 5. This thermal head drive circuit 115 is
The thermal print head 32 is driven according to control data from the control section 101 and timing signals from the timing signal generation section 102 . By driving the thermal print head 32, image data is thermally transferred onto the recording paper via the ink chip 781. In this case, as the apparatus body 1 moves, the ink tape take-up shaft 40 is rotated and U-moved by the take-up shaft drive motor 41, and the unused portion of the ink tape 81 is fed out from the supply 6 side spool 74. The used portions printed by the print head 32 are sequentially wound onto a take-up spool 73.

By moving the copying apparatus main body 1 as described above, the image data stored in the image data memo sheet 114 is sequentially printed on the recording paper sheet.

For example, if the reading process is performed as shown in FIG. 16(A), image data rBcJ corresponding to the reading range will be printed as shown in FIG. 16(B). Even in the document range where the reading position [r] actually scans, image data rAJ and rD that are invisible to the user at the start and end of reading.
Both ranges lx and Q2 of J are not printed as shown in FIG. 16(C). This enables accurate reading/printing of desired image data.

Note that the image data printed on the recording paper is
The image data is printed in the same width as the reading width, but if enlarged printing is designated in advance using the enlarged print designation key 3 in FIG. In addition, by pressing the reset/clear key 4 after printing is completed, the same self-created data can be repeatedly printed. Because it is in pressure contact with the paper, the printing
2 can be brought into contact with the recording paper sheet at a constant pressure to perform printing. Furthermore, the print head 32 is provided so that it can be rotated in a rolling manner (X), so even if the main body 1 of the apparatus is tilted to the left or right during scanning movement, the print head 32 is always rolled in the opposite direction by the angle of inclination of the main body 1. Since it makes flat contact with the surface of the recording paper, the printed image will not be blurred.

Therefore, according to the compact copying apparatus having the above configuration, by scanning and moving the main body 1 of the apparatus, it is possible not only to read the image data on the document a and print it on the surface of the recording paper, but also to Since the image data on the document a hidden in the main body 1 of the apparatus is invalidated for reading, the reading range can be easily defined and the desired copying process can be performed.

[Effects of the Invention] As described above, according to the present invention, the image data reading opening formed on the lower surface of the housing is brought into contact with the surface to be read, and the housing is moved to read the image data on the surface to be read. When reading, the image data located between the image data reading opening and the end of the lower surface of the housing in the moving direction is invalidated when the housing starts moving, and when the housing ends moving, the image data is The image data located between the image data reading opening and the end of the lower surface of the housing in the opposite direction of movement is invalidated, and the reading start and end positions with respect to the surface to be read are set at substantially the front and rear positions of the housing. Since the image data reading apparatus is configured to be able to make the determination, it is possible to provide an image data reading apparatus that can easily and accurately determine the reading start position and end position on the document.
