Next, in such a configuration, Figure 12 (revised) to (k
) and soup, the raising motion will be explained on a daily basis with reference to the timing charts shown in Figures 13 (a) to (g). That is,
The operator presses the copy key 1θ5 and selects the rear camera 1j. Then, the ``-'' priority size key 111 and high speed key 116 are selected and illuminated, and are set to the standard state. In such a state, the operator determines that the side vortices are faint, and sets the standard state to 11. Then, since the high speed key 116 is selected, the CPU 27 outputs the logic "1" from the output terminal 21a.
"The signal is output. Then, the gate of the AND circuit 95 opens, and the output of the oscillator 91 is passed through the AND circuit 95 and is directly supplied to the side vortex erroneous lighting ν8117t; and the printing section 17 as a switching clock pulse. In addition, the terminal 24
supplies the normal 'city', rr*electron l-i:V to the original data processing unit 16 and the printing section 17. Furthermore, the operator (CI numeric keypad 120) sets the number of copies to 21"t, and inserts one end of the cost price into the side spiral matchmaker IN s s and places it on the cost price mounting table 32. Then, the It knows the insertion of the vortex and outputs it to the CPU 21.CPU 21
By driving the pulse motor 39 in the forward direction, the feed roller 34 is rotated in the d direction, and by driving the pulse motor 54, the take-out roller 41 and the Q feed rollers 43 and 43 are rotated. This results in
Due to the rotation of the feed roller 34, a side vortex is taken into the can filtration sensor scanner section 3θ and grown, and one sheet of paper P is taken out from the oil supply cassette 40 by the J4i (output roller 41). When facing the reading position of the scanner section 3θ, the CPU 21 stops the rotation of the feed roller 34 by stopping the pulse motor 39.'
! 1', when the paper P taken out by the take-out roller 41 is guided to the detector 53 by the guide path 42 and the conveyance rollers 4.9 and 43, the CPU 21 switches the clutch that does not turn off. Okay, pulse motor 54
rotation is no longer transmitted to the take-out roller 41. Next, when the leading edge of the paper P is sent from the detector 53 to the transfer unit after 4 silent feeding times, the CPU 211i pulse motor 39
The pulse motor 55 is driven while sounding in the forward direction. Then, as the feed roller 34 rotates again, the folding sensor scanner section 30 photoelectrically converts the signals from the tip of the side vortex and supplies them to the CPU 21. This is it, 9
, the CPU 21 drives the thermal head 46 according to the output from the sliding sensor scanner section 30, that is, the print take. At this time, the drive wheel υ of the pulse motor 55 rotates the first general feed rollers 47, 47, the radial pressing roller 44, and the @ taking reel 52.

That is, the serial Fl'' data and left shift +s from the control 20 are supplied to the /store registers 84 and 85 in the thermal head 46. Konoto @, C
I, i', . As a result, the shift register 84 shifts the total pressure of the print data in response to the supplied clock pulse and stores it from scratch. Then, when half 247 worth of print data is stored in the soft register 84 and a strobe signal is output from the control 20, the shift register 84 outputs the recorded contents to the drive circuit 90 and enables the enable (
No. 4 prohibits input of printed data. This results in
The drive circuit 90 responds to the output of the soft resistor 84 by half of the heating resistor 72. Printing is performed using...

While this printing is being performed, the next print data and a left shift signal are supplied to the shift register 85. Then, the print data is shifted to the left according to the clock pulse supplied to the shift register 85, and then the print data is shifted to the left. and,
/The print data for half 247 minutes is recorded in the storage register 85.1.
When the controller 20 outputs the strobe signal, the 77 register 85 outputs the recorded data to the drive circuit 90 and prohibits input of print data by an enable signal. As a result, as soon as the drive circuit 90 receives the output of the shift register 85, the remaining half heating resistor 72 prints using sound. The print data for each is recorded in 1. Printing is done half a line at a time. Note that when the right/left signal is supplied, the operation is similar to that described above.

Therefore, by driving the thermal head 46, a dot pattern corresponding to the original spacing information is transferred onto the paper P using the transfer paper 45. Then, after a predetermined period of time has elapsed since the trailing edge of the document passed through the detector 37, that is, before the trailing edge of the side vortex passed through the sensor scanner unit 16, the CPU 2) rotates the pulse motor 39 in the reverse direction. 1. By driving the feed roller 34 in the C direction, the feed roller 34 is rotated in the C direction. As a result, the cost is transported in the b direction. At this time, CPU21
This causes the close contact sensor scanner section 30a and thermal sensor to stop the operation of the radar 46. Next, after the trailing end of the cost price is detected by the Chen Zhixian 37, when a time corresponding to t+1% p passes through the conveyance rollers 47, 47 once, the CPU 2 activates the pulse motor 54, By stopping the drive of the roller 55, the conveying rollers 43, 43, -, the Rad pressure roller 44, the conveying rollers 47, 47, and the winding reel 52 are stopped. The rear end of the 1M vortex is the detector 3.
7, the CPU 21 drives the pulse motor 54 to rotate the conveyance rollers 43, 43. Then, after a predetermined period of time has elapsed since the step end of the raw material 11 was detected in the incineration device 37, the CPU 21 rotates the take-out roller 41 by driving the pulse motor 54 by turning on a clutch mechanism (not shown). Furthermore, the above-mentioned predetermined time is set at the same time as when the paper P is later fed to the constant layer section and the leading edge of the sheet P is opposed to the contact sensor scanner. Then, the paper P taken out by the takeout roller 41 passes through the guide path 42 and the conveyance roller 4.
3 and 43 to the position facing the detector 53, the leading edge of the paper P is detected by the detector 53, and the CP
By disengaging the U21 (ri clutch, the rotation from the pulse motor 54 to the take-out roller 41 is completely cut off. When the leading edge of the paper P faces the transfer section, the CPU 2
1 moves the pulse motor 39 in the forward direction by i%,
The pulse motor 55 is driven. Then, feed roller 3
4 rotates, the document is optically converted by the contact sensor scanner section 30 in order from the leading edge of the document and is supplied to the CPIJ 2J. This is it! J. The CPU 27 moves the thermal head 46 in accordance with the output from the contact sensor scanner section 30. At this time, the pulse motor 55 drives the 11
7. The feed rollers 47, 47, the rad d pressure roller 44, and the take-up reel 52 are rotating. Therefore, by pivoting the thermal head 46, a dot pattern corresponding to the rg information of the document is transferred onto the paper P using the transfer paper 45. Then, when the cost price was transferred to Keiji sensor scanner Miyako 30, @, CI) U27 is the contact sensor scanner section 3.
0 and iυ operation of the thermal head 46 is stopped]-. Next, when a light-length time has elapsed for the paper P to pass through the conveyance rollers 47 and 471i, the CPU 21 stops the bouncing of the pulse motors 54 and 55, and moves the conveyance rollers 43 and 43 and the head. After that, the pressure roller 44, (^I transfer rollers 47, 47, and winding 11 reel 52 are stopped at one position.) After that, when the original mosquito reed is detected by the detector 38, the motor of the pulse motor 39 is turned on. By stopping the movement, the feed roller 34 is stopped. 5. For other copying cases such as multiple copies other than 2+Ii, single copy, etc., make 11 copies in the above simple 1 manner. It looks like this.

Next, in the above-mentioned 1 prefecture semi-state, the operator determines that the original has a dark image and presses the low rate key 117. Then, since the low speed key 117 is selected, the CPU 2) outputs 1 compensation "0" 1 ro d1 from the output terminal 21a. Then, the gate of the AND circuit 94 becomes I;
6 and printing jη≦17. Further, the power supply unit 24 supplies the power to the branch source 17 which is half the normal one. moreover,
The operator sets the number of copies using the numeric keypad J20, inserts one end of the original document into the original cost entry port 33, and places the document on the document counter 32. Hereinafter, pulse motor 39.
54 and 55 are supplied to drive the machine at a slow speed. Accordingly, power consumption can be reduced by printing at a low speed when copying a dark original as well as when copying a light original.

As described above, according to the present invention, information on the temporarily recovered object is detected by the reading section that detects the contact line tod sensor.
1, transfer this f, ;f, to the transfer gauze with a thermal transfer stamp using a thermal line head using a thermal resistor and a thermal transfer body, If there are a lot of "black t" 115 minutes on the damaged material, low-speed transfer is performed completely, and if the black part does not come off, positive-speed transfer is performed, resulting in compact size, maintenance free, and reliability. There is no need for warm-up, and the power consumption can be significantly reduced.In addition, it is possible to reduce the power consumption when the cost is high, and it is possible to additionally synthesize external information. , it is possible to provide a recording device that can be used for other purposes.
