The operation commands R and P are given to. In this case, the control unit 101 gives the operation command R to the timing signal generation unit 102 in the read mode and the operation command P in the print mode.

When the operation command R is given from the control unit 101, the timing signal generation unit 102 generates a CCD exposure timing signal of a constant cycle and at the same time synchronizes with the movement amount detection signal given from the main encoder unit 24. Various timing signals such as a number of read timing signals A, a serial / parallel conversion signal B, and a clock pulse C are generated. Further, the timing signal generator 102, when the operation command P is given from the controller 101, synchronizes with the print amount detection signal only when the forward rotation detection signal is given from the main encoder unit 24.

Here, when the timing signal generating circuit 102 does not give the main encoder pulse 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 traveling direction after the start of the reading scanning movement, the address counter 111 is provided. Since no clock pulse is generated for the read data, the read data is not actually written to the image data memory 114 until the read position reaches the end position in the read direction at the initial installation position of the apparatus body 1. At the end of the reading of the image data, 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 of travel is cleared. Therefore, in actuality, only the image data is read up to the end portion in the opposite reading direction at the final installation position of the apparatus body 1. That is, in the read state of the apparatus main body 1, the image data located between the right side edge at the main body initial installation position and the left side edge at the main body final installation position is read.

Then, when the reading of the document is completed and then the print mode is switched to, the control unit 101 outputs the operation command P to the timing signal generation unit 102 as described above, and the movement amount from the main encoder unit 24. The data stored in the image data memory 114 is sequentially read out via the data selector 113 according to the detection signal. When the controller 101 reads out 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 adjusting knob 8. The print data is output to the thermal head drive circuit 115. When the print data is sent from the control unit 101, the thermal head drive circuit 115 drives the thermal print head 32 in synchronization with the timing signal from the timing signal generation unit 102. Here, the motor drive control unit 104 gives an appropriate motor drive pulse signal to the winding 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 ribbon cassette in FIG. The ink ribbon 81 fed from the supply side spool 74 of 70 is wound around the winding side spool 73 while being in contact with 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 ribbon 81 becomes a speed that matches the movement amount of the apparatus main body 1 based on the detection signal of the motor encoder unit 47. Thus, the motor drive control unit 104 controls the torque of the winding shaft drive motor 41. When the reverse rotation detection signal is applied from the main encoder unit 24, the drive pulse for the winding shaft drive motor 41 is not output and the ink ribbon 8
The winding of 1 is not performed.

FIG. 5 is a timing signal generation circuit 102 in FIG.
First, when the read operation command R is given from the control unit 101, the counter CT is synchronized with the encoder pulse from the main encoder unit 24.
1 starts the counting operation, and the read timing signal generation circuit 102a and the serial / parallel signal generation circuit 102b cause the read timing signal A and the serial / parallel conversion unit 1 for the A / D conversion unit 109, respectively.
A serial / parallel conversion signal B for 10 is generated. Here, the counter CT1 generates a counter carry by counting an encoder pulse of a movement amount corresponding to a distance l ₁ from the reading position r on the lower surface side of the apparatus main body 1 to the end portion in the traveling direction {8th. See figure (A)},
That is, the clock pulse for the address counter 111 is generated from the address counter timing signal generation circuit 102c from the time when the read position r moves the distance l ₁ .

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

Next, FIGS. 6 (A) and 6 (B) show the structure of the paper surface detection switch 17 in FIG. 3, and the operation pin 17a has a small paper contact roller at its tip. When the apparatus main body 1 in FIG. 6 (A) is not placed on the original a or the recording paper b, the operating pin 17a projects from the lower surface of the front case 1a by 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, the sixth
In the state where the apparatus main body 1 in FIG. 1B is placed on the surface of the document a, for example, the operating pin 17a is pushed in the direction indicated by the arrow i against the spring force of the spring 17b, and the contacts 17c and 17d come into contact with each other. That is, when the apparatus main body 1 is placed on the surface of the document a or the surface of the recording paper b, the “H” (high) level signal from the paper surface detection switch 17 is output to the control unit 101.

FIG. 7 shows a combination circuit of the paper surface detection switch 17 and the operation start switch 2 described above.
The switching signals from 7 are AND gate AND4 and the corresponding inverters INV1 and INV, respectively.
Input to OR gate OR via 2 and AND gate A
The output of ND4 is input to the set terminal S of the flip-flop FF and the reset terminal R of the counter CT2, the output of the OR gate OR is input to the AND gate AND5 together with the clock pulse Φ, and the output thereof is the clock terminal C of the counter CT2.
Given to K. The counter CT2 counts the number of clock pulses Φ corresponding to a predetermined time (for example, 5 seconds), and its carry signal is given to the reset terminal R of the flip-flop FF. Then, the Q output of the flip-flop FF is given to the control unit 101 as an operation start command signal.

That is, the operation start switch 2 and the paper surface detection switch 17
Are turned on to output the operation start command signal, and one or both of the switches 2 and 17 are turned off to stop the output of the operation start command signal after a predetermined time has elapsed. That is, the operation start command signal is not output unless the user's intention and the installation state of the apparatus main body 1 on the paper surface are normal reading or printing states,
Further, during the reading scan or the print scan, the operation start switch 2 or the paper surface detection switch 17
Even if is temporarily turned off, the output of the operation start command signal is not stopped unless it is continuously turned off for a predetermined time. Therefore, during the reading or printing operation, for example, even if an operation error occurs that the apparatus main body 1 is separated from the paper surface for a moment, the reading and printing processing can be reliably performed without being stopped on the spot.

Next, the operation of the compact copying machine having the above configuration will be described. When reading information such as characters and images recorded on a document, first, the mode selector switch 6 is switched from the OFF position to the reading mode position R. When the mode selector switch 6 is switched to the reading mode position R, the power is turned on and the control unit 101 is in the reading mode. At this time, the control unit 101 controls the LED unit 107
The LED 7a for power-on display in is turned on to display that the power is turned on, and the operation command R is given to the timing signal generator 102. At this time, the cam groove engaging pin 22 shown in FIG.
And the auxiliary roller unit 18 is lowered,
The auxiliary paper contact rollers 18a, 18b are the main paper contact rollers 14a,
It projects below 14b. And then the user
In this state, the operation start switch 2 provided on the front surface of the apparatus main body 1 is turned on to move the apparatus main body 1 to the main paper contact roller 1
4a, 14b and auxiliary paper contact rollers 18a, 18b are placed in contact with the surface a of the original. At this time, for example, FIG. 8 (A)
As shown in, when only "BC" of the image data "ABCD" on the original a side is desired to be read, the right side surface of the apparatus main body 1 is aligned with the left end of the reading range. Thus, when the apparatus main body 1 is placed on the original a, the paper surface detection switch 17 comes into contact with the surface of the original a and turns on, and control is performed by turning on both the paper surface detection switch 17 and the operation start switch 2. The section 101 enters the reading operation state and the LED array 16 is turned on. Note that this is the same when printing is performed as described later, and in this case as well, the control unit 101 turns on both the paper surface detection switch 17 and the operation start switch 2.
When N, the print operation state is set. After that, when the apparatus main body 1 is placed on the original a, the scanning light is manually moved forward (toward the front of the apparatus main body 1) along the surface of the original a. The a-plane is irradiated and the reflected light is incident on the one-dimensional image sensor 57 via the imaging lens 60. On the other hand, the rotary 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 come into contact with the surface of the document a and rotate as the apparatus body 1 moves. This rotating disk 2
By the rotation of 6, the rotation amount detector 27 outputs a pulse signal according to the movement amount 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. 4, and is used as the movement amount detection signal for the copying apparatus main body 1 as the control unit 10.
1, timing signal generator 102, speed detector 103,
It is sent to the motor drive control unit 104. 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 the timing signal generator 102 receives the read operation command R from the controller 101, the timing signal generator 102 has a fixed cycle of CCD.
Generates an exposure timing signal to generate a one-dimensional image sensor 5
7, a read timing signal A and a serial / parallel conversion signal B are generated according to the movement amount detection signal given from the main encoder unit 24, and A
/ D converter 109 and serial / parallel converter 110
Output to each. Here, the timing signal generating unit 102 in FIG. 5 has a distance l ₁ in FIG. 8 (A).
The clock pulse C is generated from the time when the encoder pulse corresponding to is counted and output to the address counter 111 and the read width memory address control unit 112.

Thus, the one-dimensional image sensor 57 outputs a signal corresponding to the reflected light from the surface a of the document, that is, an image signal, in synchronization with the CCD exposure timing signal from the timing signal generator 102. This one-dimensional image sensor 57
The output signal of is amplified by the amplifier 108 and sent to the A / D conversion unit 109. The A / D conversion unit 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 generation unit 102, and a serial / parallel conversion unit 110. Output to. The serial / parallel conversion unit 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 generation unit 102, and sends it to the data selector 113. Output. When the read mode is designated, the data selector 113 is switched to the serial / parallel converter 110 side by the select signal 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 secretor 113. The write address of the image data memory 114 is the address counter 111.
Specified by the count output of. In the address counter 111, the digit address is sequentially incremented by “+1” by the clock pulse C from the timing signal generator 102, and the address of the image data memory 114 is designated. Then, the timing signal generation unit 102 causes the image data memory 114
When the image data for one line is written in, the generation of the timing signal is stopped and the main encoder unit 24 waits until the next movement amount detection signal is sent.
In this case, when the reading width of the original a is designated by the reading width designation switch 5 in advance, 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 line with the address number data corresponding to the specified read width, and repeatedly addresses the image data memory 114. That is, among the image data read by the image sensor 57, only the image data between the zero point on the width scale in FIG. 1 and the scale including the operation knob 5a is written in the image data memory 114. Become.

Since the clock pulse C is not applied to the address counter 111 until the apparatus body 1 moves the distance l ₁ , the image data read by the image sensor 57 is written in the image data memory 114 until then. It becomes invalid without fail. The same operation is repeated thereafter, and the image data read in the X direction from the right side surface position in the initial setting position of the apparatus main body 1 on the surface a of the document is sequentially written in the image data memory 114.

After that, the image data “BC” on the side of the document a is placed on the apparatus main body 1
Scan and move the left side surface position to the right end of the range to be read, and then turn off the operation start switch 2 or move the apparatus main body 1 away from the original a surface and turn off the paper surface detection switch 17, or Both switches 2,
When a predetermined time (5 seconds) has passed after turning OFF 17, the flip-flop FF is reset and a predetermined read end processing operation is started.

FIG. 9 is a flow chart showing the read end processing operation. In the state in which the operation start command signal is given by each of the switches 2 and 17, the flip-flop FF is in the set state, so that the read operation instruction is continuously issued from the control unit 101. R is output (steps S1 and S2). here,
When the user is willing to continue the reading process while the apparatus body 1 is in the scanning movement or the movement is stopped, the user mistakenly turns off the operation start switch 2 or the user makes an operation error. Even if the paper contact switch 17 is turned off due to the influence of the unevenness of the original, the switches 2 and 1 are turned off.
If 7 is quickly returned, the flip-flop FF is not reset. Therefore, steps S1 and S shown in FIG.
The process of No. 2 continues, and the reading process continues without interruption.

When the reading operation is stopped, the operation start switch 2 is continuously turned off for a predetermined time as described above.
Either the apparatus main body 1 is separated from the original a, and the contact switch 17 is continuously turned off for a predetermined time, or both switches 2 and 17 are turned off continuously for a predetermined time. In this state, the flip-flop FF is in the reset state, so that the output of the read operation command R from the control unit 101 is stopped (steps S1 → S3). Then, the data selector 113 is switched to the control unit 101 side and clear data is output from the control unit 101 to the image data memory 114, and at the same time, a down count control signal is given to the address counter 111, and a down count for a predetermined address is given. Counting is started (steps S4 to S7). Here, the predetermined address is the distance from the lower surface side reading position r of the apparatus body 1 in FIG. 8A to the end position in the direction opposite to the read signal direction, that is, the left side surface position of the apparatus body 1. The read image data corresponding to the address corresponding to l ₂ and corresponding to the distance l ₂ from the left side surface of the apparatus body 1 at the end of the reading is erased from the image data memory 114. That is, the image data from the left side surface position to the reading position r at the reading final installation position of the apparatus body 1 becomes invalid. Therefore, the range from the right side surface at the start of the scanning movement of the apparatus main body 1 to the left side surface position at the end of the movement can be defined as the read range of the image data for the original a, so that the desired image data can be easily and accurately read. Become.

Here, when the document a is read, the auxiliary paper contact rollers 18a and 18b are replaced by the main paper contact rollers 14a and 14b.
Since the device main body 1 is made to project downward, the device main body 1 is scanned and moved in a slightly tilted forward direction. Therefore, the tip of the print head 32 protruding to the lower surface of the apparatus and the ink ribbon 81 below the print head 32 do not slidably contact the surface of the original a, and the abrasion of the print head 32 and the contamination of the surface of the original a by the ink ribbon 81 are prevented. .

The speed detecting unit 103 detects the moving speed of the apparatus body 1 based on the pulse signal from the main encoder unit 24. If the moving speed is too fast, the LE is detected.
The speed warning LED 7c in the D section 107 is turned on,
The user is alerted. This is the same when printing. Further, when the remaining memory capacity of the image data memory 114 becomes low during the above-mentioned reading, the remaining memory capacity display LED 7b is turned on to notify that the remaining memory capacity is low.

Next, the operation when printing out the screen data read from the original a as described above will be described.
When printing out the image data, the mode selector switch 6 is switched to the print mode position P.
When the mode selector switch 6 is switched to the print mode position P, the control section 101 enters the print mode and the selection signal D switches the data selector 113 to the control section 101 side. At this time, the cam groove engagement pin 22 moves to the lower-stage horizontal groove portion 21a of the cam groove 21, the auxiliary roller unit 18 is raised, and the auxiliary paper-contact rollers 18a, 1
8b has the same protrusion level as the main paper contact rollers 14a and 14b. In this state, the user places the copying machine body 1 with the paper contact rollers 14a, 14b and 18a, 18b in contact with the outer recording paper b surface such as a notebook. In this way, 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 surface and turns on, and the print head 32 contacts the recording paper b surface via the ink ribbon 81. . In this case, the print head 32 compresses the pressing spring 33 by contact with the recording paper b, and the respective paper contact rollers 14a, 14b.
And 18a and 18b to the recording paper contact level, and the repulsive force of the pressing spring 33 makes pressure contact with the recording paper b surface. After that, 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 and moved forward along the recording paper b surface, the apparatus main body 1 moves. Accordingly, the respective paper contact rollers rotate, and the rotation of the second main paper contact roller 14b is transmitted to the rotary disk 26 via the rotation transmission belt 28. Along with the rotation of the rotary disc 26, a movement amount detection signal corresponding to the movement speed of the apparatus main body 1 is taken out from the main encoder unit 24 as in the above reading.

When the moving amount detection signal and the normal rotation detection signal are output from the main encoder unit 24 by starting the forward movement of the apparatus 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 rotationally driven, the take-up spool 73 of the ink ribbon cassette 70 is rotated in the take-up direction, and the ink ribbon 81 fed from the supply-side spool 74 serves as a heat generating portion of the thermal print head 32. The winding side spool 73 is wound up. 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 104 determines the winding speed of the ink ribbon 81 based on the detection signal given from the motor encoder unit 47. The torque of the winding shaft drive motor 41 is controlled so as to match the movement amount of 1, that is, the printing speed. This motor torque control is performed every time the winding shaft drive motor 41 makes one rotation.
Is performed by comparing the pulse signal period from the motor encoder unit 47 with the number of encoder pulses from the main encoder unit 24. The encoder provided from the main encoder unit 24 while the motor 41 makes one rotation. When the number of pulses is larger than a predetermined value (when the moving speed of the apparatus body 1 is faster than the ribbon winding speed), the motor drive pulse width is increased to increase the ribbon winding speed, and the encoder pulse When the number is smaller than the predetermined value (when the moving speed of the apparatus body 1 is slower than the ribbon winding speed), the motor drive pulse width is shortened to reduce the ribbon winding speed. this is,
The same applies when the ribbon winding diameter of the take-up side spool 73 increases and the load on the motor 41 increases. Even when the ribbon winding speed slows down due to the increase in the load on the motor 41, the motor 41 Since the number of encoder pulses during one rotation of becomes larger than a predetermined value, the torque of the motor 41 is also automatically increased at this time and the ribbon winding speed is increased.

On the other hand, the control unit 101 outputs a one-line printing command to the timing signal generation unit 102 in response to the movement amount detection signal sent from the main encoder unit 24, and the timing signal generation unit 102 drives the thermal head. The print timing signal is output to the circuit 115. Further, the control unit 101 sequentially designates the row and column addresses of the image data memory 114 according to the movement amount detection signal from the main encoder unit 24, and sets the image data stored in the image data memory 114 to the data selector 113. The data is read out through the head and output to the thermal head drive circuit 115 for each row.

When a one-line print command is given, the control unit 101 performs thermal control based on the number of black characters in the 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 energization time for the print head 32 is set, and the image data read from the image data memory 114 is output to the thermal head drive circuit 115. The thermal head drive circuit 115 drives the thermal print head 32 according to the control data from the control unit 101 and the timing signal from the timing signal generation unit 102. By driving the thermal print head 32, the image data is thermally transferred onto the recording paper b via the ink ribbon 81. In this case, as the apparatus main body 1 moves, the ink ribbon winding shaft 40 is rotationally driven by the winding shaft drive motor 41, the unused portion of the ink ribbon 81 is sent out from the supply side spool 74, and the thermal print head 32 is The used part after being printed by is the spool 73 on the take-up side.
It is wound up in sequence. As described above, the copying apparatus main body 1
The image data stored in the image data memory 114 is sequentially printed on the recording paper b by moving the.

Here, for example, when the reading process is performed as shown in FIG. 8 (A), the image data “BC” corresponding to the reading range is printed as shown in FIG. 8 (B). Even in the original range where the reading position r is actually scanned and moved, the partial ranges l ₁ and l ₂ of the image data “A” and “D” which are not visible to the user at the start of reading and at the end of reading are the first It is not printed as shown in FIG. 8 (C). This enables accurate reading / printing of desired image data.

The image data printed on the recording paper b is the original a.
It is printed with the same width as the reading width from
If the enlarged print is designated by the enlarged print designation key 3 in the figure, the image data can be enlarged to a predetermined ratio and printed. Further, by pressing the reset / clear key 4 after printing, the same image data can be printed repeatedly.

Therefore, according to the small-sized copying machine having the above structure, not only the image data on the original a can be read and printed on the recording paper b side by scanning and moving the apparatus main body 1, but also the operation start switch 2 and the paper surface detection can be performed. When both the switches 17 are turned on, the control unit 101 outputs the read or print operation commands R and P. Therefore, for example, when reading image data, the lower surface of the apparatus main body 1 is not reliably in contact with the original a surface. At the same time, no read operation is started.

Also, during the reading or printing operation, the operation start switch 2 or the paper surface detection switch 17 is temporarily turned off.
However, the output of the operation commands R and P from the control unit 101 is not stopped unless the state is continuously turned off for a predetermined time.
For this reason, even if the operator intends to continue the operation even when the apparatus main body 1 is being manually scanned and moved, or when the operator starts the operation start switch 2 due to an operation error, Even if the paper contact switch 17 is turned off due to an operator's operation error or unevenness of the original / print medium surface, if the switches 2 and 17 are quickly returned, the reading or printing operation can be performed. It can be continued without interruption.

[Advantages of the Invention] As described above, according to the present invention, an operation switch for operating the reading unit or the printing unit, a counting means for detecting that the operation switch is off and counting for a predetermined time, and the operation switch. When it is turned on, the reading unit or the printing unit is operated, and the counting unit ends the operation when the counting of the predetermined time is finished. Provided is a small image data processing device capable of preventing a reading error or a printing error due to an operation error of the apparatus body without immediately stopping the reading or printing operation when the operation switch is turned off. it can.
