This transfer iron 31 is composed of a heater such as a nichrome wire, and heats and melts the thermal transfer ink printed on the outer peripheral surface of the mask film 2°, and transfers it onto the recording paper outside the main body case 1. be. In order to improve the response speed of the heater and reduce the current consumption, the transfer iron 31 may have the same structure as a normal thermal head. However, in this case, the heat dissipation resistor formed on the ceramic substrate is continuous in the longitudinal direction, and a pair of lead wires are provided in parallel with the heat dissipation resistor, with one of the lead wires facing the active side and the other. It is desirable to connect it to GND. Furthermore, as another method of forming the transfer iron 3, an element such as a POSISTOR which can control the temperature rise within a certain range may be used.

In the figure, reference numeral 41 denotes a changeover switch provided on the outer surface of the main body case 11 (1), and a signal inputted through this changeover switch 4 is then sent to a mode generation section 42. The mode signal generator 42 generates a mode signal corresponding to the operation mode set by the changeover switch 41, and transmits this mode signal to the system control circuit 43 while the execution key 31 is pressed.
Send to.

This system control circuit 43 controls the operation of all other circuits according to the mode signal input from the mode signal generator 42, and outputs a drive signal to the LED driver 44 when reading an image, and also outputs a drive signal to the CCD driver 44. A control command is sent to the image sensor 15. The LED driver 44 drives the LED according to a drive signal from the system control circuit 43.
The array 13 is driven, the LED array 13 is turned on, and the document 45 is illuminated.

The light reflected by the original 45 is collected by the condensing lens 14 and then sent to the CCD image sensor 15.

The CCD image sensor 15 takes in image data corresponding to the input image in response to a timing signal from the system control circuit 43, and outputs this as a voltage signal.

This voltage signal is amplified by an amplifier 46 and then sent to a ~Φ converter 47. The A/D converter 47 compares the voltage signal representing each image data with a reference voltage and converts the comparison result into a digital value. The voltage signal converted to a digital value is then converted to a serial/parallel (S/P) converter 4.
Sent on 8th. Then, in this S/P converter 48, i+
The parallelized data is then transferred to the system control circuit 4.
Sent to 3. The system control circuit 43 sends image data to the printer control section 49. The printer control unit 49 sends control data to the thermal head driver 50 in accordance with the sent image data, and causes the thermal head 30 to heat and print an image on the master film 20. Further, while the changeover switch 4 is set to [PRINT 0UTJ mode and the execution key 33 is pressed, the printer control unit 49 also sends control data to the iron driver 51, heats the transfer iron 31, and heats the master film. The ink image printed on 20 can be transferred to recording paper.

Next, the operation of the above embodiment will be explained.

FIG. 2 shows the appearance during reading. First, when reading an image, first turn the selector switch 41 to
RPRINTJ image reading and master film 2
Set to 0 printing mode. Next, with the lower end surface 11h side of the main body case 11 facing the document 45 side, the grounding rows 216, 16 are placed on it in correspondence with the part to be read, and set as shown in FIG. . In this state, the main body case 11 is manually moved while pressing the execution key 33, thereby causing the grounding rollers 16, 16 to roll onto the original 45. As a result of the above operations, when the mode signal of the changeover switch 41 is input to the system control circuit 43, the system control circuit 43 enters an image reading state. The system control circuit 43 sends a drive signal to the LED driver 44, and when the LED array 13 is turned on, one line of the image of the length of the slit 12 is sequentially transmitted through the condensing lens 14 to the
It concludes on OD image seven sensors 15. This COD image sensor 15 is a linear CCD, and receives a reference clock and a shift gate clock synchronized with this reference clock from the system control circuit 43. After the output signal of this COD image analyzer 15 is amplified by an amplifier 46,
The signal is sent to an A/D converter 47. In the A/D converter 47,
The input analog value data is converted into digital image data and sent to the S/P converter 48. S
The /P conversion unit 48 converts the sent image data into parallel data and outputs it to the system control circuit 43. The system control circuit 43 sends this image data to the printer control section 44. The printer control unit 44 sends control data to the thermal head driver 50 in accordance with this image data, and selectively heats the line-type thermal head 30 to print one line of the image on the master film 20. In this way, printing of one line of the image is completed.

During this operation, the case body 11 is moving over the document 45 due to manual scanning, and the grounding roller 1 is moved accordingly.
6 is rotating. The rotation of the grounding roller 16 is transmitted to the sheet feeding roller 17 via the feeding wire 18, and the sheet feeding roller 17 rotates the master film 20 together with the sheet feeding roller 219. Therefore, by continuously printing one line as described above, the entire read image is printed on the master film 20.

That is, the printing mechanism in this embodiment prints thermal transfer ink on the master film 20 at the same time as image data is read. is printed in reverse. Furthermore, when the reading speed becomes lower than a predetermined speed, thermal transfer ink will be printed in duplicate. However, this does not cause any problem in printing accuracy.

Thereafter, as shown in FIG. 4, the image is transferred to an arbitrary recording paper. To prepare for transfer, hold the case body 11, rotate the grounding roller 28 to rotate the master film 20, and position it so that the leading part of the printed image is at the position of the transfer iron 31. Thereafter, as shown in FIG. 4, the case 13 and the other end surface 11b of the main body 11 are brought into contact with an arbitrary recording paper 52, and the changeover switch 41a is set to [PRINT 0UTJ]. The mode signal of this changeover switch 41a is input to the system control circuit 43 while the execution key 33 is pressed, and the system control circuit 43 sends control data to the iron driver 51 and transfers the image when the image is not transferred. 3) Heat evenly. Therefore, when the case body 11 is manually scanned, the rotation of the grounding row 228 is controlled by the feed wire 2.
7 to the sheet feed roller 17, and the sheet feed roller 17 is rotated to rotate the master film 20. As a result, the ink images printed on the master film 20 are sequentially melted by the heat of the transfer iron 3 and transferred onto the recording paper 52. Generally, the printing speed of thermal printing devices is limited by the thermal responsiveness of the thermal head, but since the transfer iron 31 is heated uniformly, there is no such limitation, and by applying a sufficient amount of heat, High-speed paper transfer is possible. Further, in the above embodiment, since there is no need to store and hold the read image data, it is possible to reduce the current consumption required for storing the image data.

Further, as a printing mechanism for printing an ink image on the master film 2o, it is also possible to use a thermal ink roller in which a porous roller made of urethane or the like is impregnated with thermal transfer ink, as shown in FIG. Figure 5 (,) shows a thermal ink roller 54 equipped with a preheater 53 in its core.
This is an example using . In this case, the entire preheater 53 is preheated and the thermal ink roller 54 is heated.
The thermal ink oozing out from the thermal ink roller 54 is used as a platen to press the master film 20 from the opposite side and selectively heat the master film 20 using the thermal head 30.
It is printed on the master film 20 by.

FIG. 5(b) shows the thermal ink roller 54, master film 20 and U thermal shown in FIG. 5(,) above.
An ink layer forming row 255 is provided between the card 30 and the ink layer forming row 255. In this case, the thermal transfer ink that has been entirely preheated by the preheater 53 and oozes out from the thermal ink roller 54 is once applied as a thin film to the human blood on the ink layer forming roller 55 adjacent to the thermal ink roller 54 . This ink layer forming roller 55 is also circumscribed with an ink layer thickness adjusting roller 56.
The ink layer thickness of the ink applied to the ink layer is appropriately adjusted by the pressing force of the ink layer thickness adjusting roller 56. Then, the thermal ink coated on the ink layer forming roller 55 and having an adjusted ink layer thickness is applied to the ink layer forming roller 55.
5 as a platen, the master film 20 is pressed from the opposite side, and printed on the master film 20 by the thermal head 30 that selectively heats it. By using the thermal ink roller 54 impregnated with such thermal transfer ink, the ink replenishing means can be made smaller and have a longer service life without using the ink cartridge 21.

Further, in the above embodiment, an endless type of master film 20 was used, but the invention is not limited to this. Similarly to the above ink ribbon 21, it may be wound internally on a roll and led out from the end. It's okay. 6th
The figure shows another embodiment of the present invention having such a configuration, and the basic configuration is the same as that shown in FIG. is omitted.

In the figure, 57 is a master film wound around a master film roller 58. This master film 57 is supplied together with the ink ribbon 21 between the platen 29 and the thermal head 30, and after an ink image is printed there, it is temporarily stored in the film tank 59. Then, the ink ribbon 21 is pulled out from the film tank 59 by sheet feed rollers 17 and 19 that rotate in conjunction with the rotation of the ground row 228, and the master film 57 is transferred to the roller 60, the transfer iron 3, and the transfer iron 3. 61 to the case body 11 (not shown).
derived outside of. At this time, the master film 57 is heated by the transfer iron 31 to transfer the E1Funk image onto the recording paper 52 placed on the table 62, and then cut off by the cutter 61.

With this configuration, after an image is read and recorded on the master film 57, the master film 57 is pulled out of the film tank 59 and placed on the recording paper 52, and after accurate positioning, transfer is performed. becomes possible. Furthermore, since the master film 57 is disposable, it has slightly lower heat resistance and is less expensive. Materials such as lyester can be used. Further, the ink replenishing means is an ink roll type as shown in FIG. 5 instead of the master film 57, and the platen 29 is replaced by the sheet feeding roller 21.
If the drive roller rotates in the same direction as the master film 57, it is also possible to use a recycled film made of polyimide or the like as the master film 57.

In the above embodiment, the read image data is simply transferred to the recording paper as is, but image information is attached to each read image data, and an image information memory is provided to store this image information. It is also conceivable to control the image data to be processed.

[Effects of the Invention] As detailed above, according to the present invention, print information is once printed on a recording medium inside the device, and the information printed on this recording medium is transferred to any record outside the device. It is possible to obtain a printing device that can transfer onto paper, and there is no need to install printing paper inside the device, so there is no need to leave any printing paper behind! ! It has the advantage that there is no need to worry about ', and it is very convenient because it can be printed on a notebook or any data paper.
