Abstract

PURPOSE:To prevent the deterioration of picture quality at the initial stage of transfer by idle-feeding an ink donor film immediately after transfer is started, giving the ink donor film tension and conducting transfer. CONSTITUTION:When a thermal head 25 is moved on recording paper B from a position where the thermal head 25 is pressed onto recording paper B, a transfer-start position setting section 68 sets a region (a non-transfer region) not transferred. A fixed quantity of an IDF 23 is idle-fed during a time when drive is started, and the IDF 23 is wound on an IDF take-up roll 21. The IDF 23 is pulled between an IDF feed roller 22, to which back tension is applied, and the IDF take-up roller 21, on which the IDF is wound, by the idle-feed and given tension, thus removing creases, etc. during idle-feed. Accordingly, since the IDF 23 is brought to the state of proper stretching at the time of the start of transfer, excellent transfer, in which there is no transfer slip-off, etc., can be performed while the IDF can also be wound smoothly.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hand-driven transfer device that is manually moved on a recording medium to transfer an image, and particularly relates to a hand-driven transfer device that transfers an image by moving it on a recording medium, and in particular, it is used for transferring an ink donor film as a transfer medium. The present invention relates to a hand-driven transfer device that can perform its initial operation well.

[Conventional technology]

A hand-driven transfer device is a copying device that transfers an image onto a recording medium as it moves over the recording medium. For transfer, supply the ink toner film so that it comes into contact with the thermal head,
This is done by melting the ink in the ink donor film using heat generated by a thermal head in response to an image signal and transferring it onto the recording medium. The ink donor film is passed between a pair of rolls, and as it moves over the recording medium, it is unrolled from one roll, passes through a thermal head, and then is wound onto the other roll. There is.

FIG. 63 shows the initial state of transfer in such a conventional hand-driven transfer device, in which two guide bars 300 and 30
A thermal head 302 is provided between the guide bar 301 and the ink toner film 303. After passing through the guide bar 300, the ink toner film 303 comes into contact with the thermal head 302, and is then sent out from the guide bar 301. During transfer, a predetermined pressure is applied to the thermal head 302 and the thermal head 302 is moved over the recording medium, and this pressure causes the thermal head 302 to move upward, albeit slightly, and in this state a heat generating operation is performed.

[Problem to be solved by the invention]

However, in the conventional hand-driven transfer device, the sixth
As shown in Figure 3, the ink donor film may be wrinkled or wavy.

This is because the tension of the ink donor film disappears when the ink donor film moves upward due to pressure contact onto the recording medium. When transfer is performed in such a state, the wrinkles become wavy, resulting in transfer omissions in which a portion of the image is not transferred at the beginning of transfer, and the quality of the transferred image is significantly degraded.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a hand-driven transfer device that can keep an ink donor film under tension in order to prevent image quality deterioration at the beginning of transfer.

[Means to solve the problem]

In the present invention, immediately after the start of transfer, the ink toner film is conveyed emptyly to apply tension to the ink toner film, and then,
It is designed to perform transcription, and is provided with transcription control means for this purpose. The transfer control means that performs the above operation provides a time difference between winding of the ink donor film and heat generation of the thermal head at the beginning of movement on the recording body, and delays the thermal head by a predetermined time with respect to winding of the ink donor film. The structure is such that it generates heat. The transfer control means for this purpose may be a mechanical control mechanism that winds the ink donor film so that the amount of the ink donor film to be wound is greater than the distance traveled on the recording medium, and the distance traveled on the recording medium is measured. However, it may be an electrical control means that drives the thermal head when the moving distance reaches a predetermined set value (for example, 5 dragons).

[Effect]

With the above configuration, the thermal head is not driven at the beginning of movement on the recording medium, and only the ink 1 nap film is wound up. By this winding, the ink donor film is brought into a predetermined tension state, wrinkles, squiggles, etc. are removed, and the ink donor film becomes ready for transfer.

〔Example〕

FIG. 1 shows an overall perspective view of a hand-driven copying apparatus 1, which includes a recording section 2 at the top and a reading section 3 at the bottom. Both sides of the reading section 3 extend upward to form connecting arms 1 and 4, and the connecting arms 4 are rotatably attached to both sides of the recording section 2. Further, a write/write button 5 is attached to the center of the upper end of the recording section 2, and by pressing this button 5, the original is read and transferred to a recording medium such as recording paper. Furthermore, a power button 6, a read/write lamp 7, and a transfer magnification button 8 are arranged on the outer surface of the recording section 2, and a speed lamp 9, a memory lamp 10, and a magnification display lamp 1) are arranged on the sides thereof. has been done.

The power button 6 is a button for turning the power on and off, and reading or transfer is possible by pressing the read/write button 5 while the power button 6 is in the ON state. The transfer magnification button 8 is a button for selecting the transfer magnification,
The selected magnification is displayed by the magnification display lamp 1). Read/write lamp 7 is read/write button 5
It lights up when pressed, and turns off when the pressure is released.

The speed lamp 9 displays the scanning speed for reading operations and transfer operations. When the scanning speed is within the appropriate range, it lights up in green, for example, and when the scanning speed is out of the appropriate range, it lights up in red, for example. Light. Therefore, the operator can perform proper reading and proper transfer by scanning at a speed that keeps the speed lamp 9 in a green state without looking at the color of the speed lamp 9. The memory lamp 10 displays the readable memory capacity; within the memory capacity range, it lights up in green, for example, and when the memory capacity is exceeded, it lights up in red, making it impossible to read. Such a hand-driven copying apparatus 1 is in a readable state (read mode) when the reading section 3 is located directly below the recording section 2 as shown in FIG. The device 1 is placed on the document A, and while in contact with the document A, the read/write button 5 is pressed and pulled toward the user (sub-scanning) to read information on the document and record its contents. On the other hand, Fig. 3 (
As shown in a), when the connecting arm 4 is rotated so as to bend the reading section 3 toward the front, and the recording section 2 and the reading section 3 are separated, the transfer is possible (Rye 1 to mode). In this write mode, as shown in Figure 3 (bl), place the recording unit 2 on a recording medium such as recording paper B, and pull it towards you while pressing the read/write button 5 while in contact with the recording paper B. It is possible to write the information.

4 and 5 show a sectional view and a schematic perspective view of the recording unit 2, and show drive rollers 13 and 14 made of rubber or the like.
is provided at the bottom of the housing 12. Drive roller 13
and 14 are arranged in parallel to each other in front and behind each other, and when the recording section 2 is placed on the recording paper B, at least one of them comes into contact with the recording paper B. And recording section 2
When scanned on recording paper B, drive rollers 13 and 14
rolls on recording paper B.

The drive rollers 13 and 14 are interconnected by a belt 15, so that when one of them rotates, the rotation is transmitted to the other. Of the drive rollers 13 and 14, the drive roller 13 located at the front in the scanning direction is connected to an encoder 17 via a belt 16, and the rotation speed of the drive roller 13, that is, the moving distance of the recording unit 2 is determined by the encoder 17. The encoder 17 outputs a position signal corresponding to the distance traveled.

Further, the drive roller 13 is connected to a rotating shaft 19 via a belt 18. The rotating shaft 19 is coaxially equipped with a torque transmitting section 20 having a dork remining function, and the rotation thereof is transmitted to the take-up roll 21 of the ink donor film (hereinafter abbreviated as IDF) 23 via the torque transmitting section 20. Ru. The IDF take-up roll 21 winds up the IDF 23 from the IDF supply roll 22 under hack tension.

In this case, the IDF 23 is pulled out from the IDF supply roll 22, passes through a guide bar 24, a thermal head 25, and a guide bar 26, and then is wound onto the IDF take-up roll 21. The thermal head 25 is controlled by the control section of the control board 27, generates heat in response to image signals read from the memory 28, heats the IDF 23, and heats the IDF 23.
Melt the ink that is impregnated with. As a result, the image is transferred onto the recording paper B. In this structure in which the two drive rollers 13 and 14 are connected by the heald 15, operability is improved when the recording unit 2 is placed on the recording paper B and the recording paper B is manually scanned. In general, in manual scanning, the housing 12 is in the operating direction (i.e., in the advancing direction).
Easy to tilt back and forth (, either one of the drive rollers 13
Alternatively, the roller 14 is lifted off the top of the recording paper B, but even in this case, the other drive roller 13 or 14 is pressed onto the recording paper B and rotates. This rotation is transmitted to the floating drive roller 13 or 14 by Hello 5,
Rotate that roller. For example, if the housing 12 is tilted rearward in the direction of movement and the drive roller 13 is lifted up, the drive roller 14 comes into contact with the recording paper B and the recording unit 2
It rotates as it moves. This rotation is transmitted to the drive roller 13 via the heald 15, and the drive roller 13 rotates. Therefore, drive roller I3 and heald 16.
The rotation is transmitted to the encoder 17 and the rotary shaft 19 which are connected by the encoder 18, and the encoder 17 accurately counts the distance moved and outputs an accurate position signal, so that the image is accurately recorded and ,
I by the IDF take-up roll 21 due to the rotation of the rotating shaft 19
Since the winding of DF23 is performed reliably, IDF23
A high-quality image can be obtained without sagging or wrinkles.

Furthermore, since the recording section 2 can be prevented from meandering when the two drive rollers 13 and 14 are in contact with the recording paper B,
The straightness of the recording unit 2 during scanning can be ensured. Note that a detection roller 31 of a contact detection means 30, which will be described later, is provided on the same line as the axis of the drive 13.

FIG. 6 shows the rotation of the rotating shaft 19 by the IDF winding roll 2.
1, which rotates coaxially with the rotating shaft 19 that receives rotation via the heald 18.
A rubber member 20b is fixed to the outer periphery of the rotating member 20a. - The rubber member 20b has a plurality of elastically deformable protrusions 20
The protrusion 20c is elastically engaged with the inner circumferential surface of the second rotating portion A20d located on the outer periphery of the protrusion 20c. The second rotating member 20d is rotationally connected to the IDF take-up roll 21 and performs the same rotational movement.

Generally, as recording progresses, as the winding diameter of the IDF winding roll 21 increases, a large torque is required to wind it. Therefore, the protrusion 20C of the member 20b, which is fixed to the first elastic member 20a that rotates at the same time as the rotary shirt eye 9, is elastically deformed in accordance with the rotation 1 to 1, and the projection 20C of the member 20b is elastically deformed between the rotation member 20d and the second rotating member 20d. A slip occurs depending on the rotational torque. As a result, the winding roll 21 is decelerated and its circumferential speed is kept constant. In this way, the ink donor film 23
Since the ink donor film is wound up at a winding speed that precisely corresponds to the amount of movement of the recording unit 2, even if the speed changes due to manual drive operation, the amount of movement and the circumferential speed of the ink donor film are kept consistent.

FIG. 7 is a block diagram showing an example of transfer control of the thermal head 25. In FIG. This control is achieved by feeding IDF23 without performing any transcription at the time of transcription initiation.
This is to remove wrinkles on the IDF 23 that occur at the beginning of transfer. The transfer control means 65 is the drive roller 13
a counter 66 that measures the pulse signal from the encoder 17 that receives the rotation of the encoder 17 and converts the amount of movement of the recording section due to manual scanning; a comparator 67 for comparing the transfer start position, a transfer start position setting section 68 for setting the transfer start position,
A driving section 69 that drives the thermal head 25 based on a signal from a comparator 67 is provided. Such a transfer control means 65 is incorporated into the control board 28 of the thermal head shown in FIGS. 4 and 5, for example. The transfer start position setting section 68 moves the thermal head 25 to the recording paper B.
When the thermal head 25 is moved on the recording paper B from the position where it is in pressure contact with the paper B, the area where no transfer is performed (non-transfer area)
This is to set. The counter 66 counts the time when the thermal head 25 is pressed against the recording paper B as "0",
The amount of movement of the thermal head 25 is measured in fin units or 0.1) units from the pulse signal input from the encoder 17. The comparator 67 compares this movement amount with a set value (8 pulses/drunk). As a result of the comparison, if the amount of movement is less than the set value, no signal is issued to the drive unit 69, but if the amount of movement is greater than or equal to the set value, a signal is issued to the drive unit 69, thereby causing the drive unit 6
9 drives the samarhenod 25. This drive causes the transfer to the recording paper B, but until this drive is started, the IDF 23 is idly fed by a predetermined amount and is wound up on the IDF take-up roll 21. With this empty feed, the ID
F23 is Ba.

Since tension is applied between the IDF supply roll 22, which is under tension, and the IDF take-up roll 21, which winds up the TDF, wrinkles and the like are removed during idle feeding.

Therefore, at the start of transcription, IDF2
3 is in an appropriate tension state, so that the transfer plate can perform good transfer without any defects, and can also be smoothly wound.

Note that such an operation can be performed by setting the winding amount of the IDF winding roll 21 without incorporating the transfer control means 65. That is, the IDF take-up roll 2 is adjusted so that the amount of winding of the IDF take-up roll 21 is always greater than the amount of movement of the IDF 23 passing through the thermal head 25.
This can be done by energizing 1.

The contact detection means 30 includes a detection roller 31 that rolls on the recording paper B as shown in FIG.
The IDF supply roll 22 is provided with a contact detection section 32 that detects contact or non-contact, and a stopper means 33 that stops the rotation of the IDF supply roll 22 in response to a signal from the contact detection section 32. The detection roller 3I is always urged downward (towards the recording paper B) by a biasing means (not shown) such as a spring, and the recording section 2
When the housing 12 is placed on the recording paper B, it is pushed up by the recording paper B and moves upward against this urging force.

On the other hand, when the housing 12 is lifted and separated from the recording paper B, it is moved downward by the biasing means. The contact detection section 32 detects this movement of the detection roller 31 optically or mechanically. For optical detection, for example, an optical sensor may be used in which a slit (not shown) is formed in the detection roller 31 and light emitting elements (both not shown) are provided on both sides of the slit. An image sensor (not shown) that forms a mark and optically detects the amount of movement of the mark may be used. On the other hand, mechanical detection is performed by, for example, the detection roller 31
The stopper means 33 can be constructed by using a rod or an arm (none of which are shown) that moves up and down integrally with the stopper means 33. In the case of a contact detection section that performs optical detection, in addition to the above-mentioned sensor, a drive section (not shown) that drives the stopper means 33 based on the output signal of this sensor is appropriately incorporated. The stopper means 33 locks the rotation of the IDF supply roll 22 based on a command from the contact detection section 32,
It acts to release this lock. In the illustrated example, the stopper means 33 includes a lock pawl 34 whose bent end has a pointed shape;
It consists of a plurality of lock grooves 35 formed at one end of the IDF supply roll 22. The lock pawl 34 operates to approach and separate from the lock groove 35, and when the lock pawl 34 engages with the lock groove 35, the IDF supply roll 2
While the rotation of the IDF supply roll 22 stops, when this engagement is released by the separation of the lock claw 34, the IDF supply roll 22 becomes rotatable. In this case, the engagement of the lock claw 34 with the lock groove 35 is detected and controlled so that the 1-ra 31 is in a non-contact state away from the recording paper B, that is, in a state where the entire recording unit 2 is lifted from the recording paper B. Ru. That is, when recording the image is finished and the recording section 2 is lifted from the recording paper B, the lock claw 34 and the lock groove 35 are engaged with each other, and the IDF supply roll 2 is closed. Therefore, almost at the same time as the recording unit 2 is lifted up, the I
Since the supply of the IDF 23 from the DF supply roll 22 is stopped, unnecessary feeding of the IDF 23 is avoided (and generation of slack or wrinkles in the IDF 23 on the IDF supply roll 22 side can be prevented. When the housing 12 is placed on the recording paper B, the detection roller 31 is pushed up and
Due to the dirt, the stopper claw 34 separates from the stopper groove 35 and the engagement is released. As a result, the IDF supply roll 22 becomes rotatable and rotates as the recording unit 2 scans 7.
DF23 is supplied.

When such a contact detection means 30 is provided, when the copying apparatus 1 is lifted and the housing 12 of the recording section 2 is separated from the recording paper B, the IDF supply roll 22 is forcibly rotationally locked instantly and the IDF 23 is locked. Delivery stops. Therefore, the ID stuck to the recording paper B behind the thermal head 25
F can be peeled off as is, allowing clear images to be recorded. Recording on the recording paper B by the IDF 23 is performed by the heat generated by the thermal head 25, and this heat causes the IDF to
The ink and wax impregnated into the recording paper 23 are melted and transferred onto the recording paper B. After this transfer, the wax solidifies after a predetermined cooling time (for example, about 0.3 sec), thereby making it possible to obtain an image with reliable density. That is, in order to obtain a clear image, it is necessary that the IDF 23 after melting the ink or wax remains fixed to the recording paper B for a predetermined period of time. When the contact detection means 30 is provided,
Since feeding of IDF from the IDF supply side is stopped, the IDF does not protrude behind the thermal head 25, and the IDF 2 after transfer located behind the thermal head 25
The fixed state with the recording paper B of No. 3 can be maintained. This ensures solidification of the wax and makes the image clearer.

Next, the operation of recording on the recording paper B using the above configuration will be explained.

First, as shown in FIG. While pressing the read/write button 5, lightly press the recording unit 2 against the recording paper B, and move the entire recording paper B from the upper end to the lower end, that is, in the sub-operation direction.In this state, the detection roller of the contact detection means 30 31 moves upward and the stopper means 33 is unlocked, so that the IDF supply roll 22 is in a rotatable state.
At least one of the recording paper B contacts the recording paper B, and the movement causes the drive roll 13 to rotate directly or via the drive roll 14 and the heald 15, and the encoder 17 and the rotating shaft 19 to rotate via the heald 16.18.

When the encoder 17 outputs a position signal corresponding to the moving distance, the control section 27 reads out an image signal from the memo IJ 28 and drives the thermal head 25. At the same time, the rotating shaft 19 is
I) The F winding roll 21 is rotated, and this rotation pulls out the IDF 23 against the back tension of the IDF supply roll 22 and winds it up. As a result, the 1DF 23 passes through the thermal head 25.

At this time, when the heating resistor of the thermal head 25 selectively generates heat in accordance with the image signal, the 10F23 is heated to melt ink and the like, and an image is recorded on the recording paper B.

FIG. 9 shows a separate perspective view of the contact detection means 30, in which a detection roller 31 that rolls in contact with the recording paper B is pivotally supported by a bracket 36. The bracket 36 is provided on the inner surface of the housing 12 so as to be movable up and down, and is urged upward by a spring 37. As a result, the detection roller 31 is also urged upward. Also, the bracket 36 includes an encoder 1.
7 is supported, and a belt 38 is passed between the shaft of the encoder 17 and the detection roller 31. In such a structure, the detection roller 31 is pressed onto the recording paper B by the spring force of the spring 37, so when the copying device 1 is scanned, the detection roller 31 rotates according to the amount of movement, and this rotation causes the belt 38 to rotate. is transmitted to the encoder 17 via the encoder 17, and the amount of movement is counted. That is, the detection roller 31
The roller also serves as a roller for detecting the amount of movement of the copying device. The bracket 36 is integrally formed with a lock pawl 34, and the TDF supply roll 22 is provided with a lock groove 35 in which the lock pawl 34 engages. Rotation is stopped and released.

In such a configuration, when the housing 12 of the recording section 2 is pressed against the recording paper B, the bracket 3 is pressed together with the detection roller 31.
6 moves upward to release the engagement between the lock pawl 34 and the lock '/a 35, and as the casing 12 moves, the IDF supply roll 22 rotates and the IDF 23 is smoothly supplied. With this supply, the IDF 23 is heated by the thermal head 25 and is fixed to the recording paper B. This fixed state is maintained until the guide bar 26 moves to the position of the thermal head 25, that is, the distance between the guide bar 26 and the thermal head 25 is maintained, and the image is transferred. next,
When the housing 12 is lifted from the recording paper B, the detection roller 31 and the bracket 36 are moved downward together by the spring force of the spring 37, and the lock pawl 34 engages with the lock groove 35. This locks the rotation of the IDF supply roll 22 and removes excess IDF.
Since the DF 23 is not fed out, the IDF 23 stuck to the recording paper B on the rear side of the thermal head 25 can be peeled off from the recording paper B after the ink and wax are solidified.

FIG. 10 and FIG. 1) show the IDF supply roll 22, IDF take-up roll 21,
The member including the cartridge 4o is made removably attachable to the housing 12 of the recording section 2. The cartridge 40 includes a unit frame 41 that can be fitted into the open lower end portion of the housing 12, and an ID whose both ends are pivotally supported by the unit frame 41.
E-supply roll 22 and IDF take-up roll 21, and two wooden tri-rollers 13 and 14 that are hung on the frame 41.
The IDF 23 is drawn out from the IDF supply roll 22 and wound onto the IDF take-up roll 21. The unit frame 41 has an insertion window 41 on the upper end surface.
a is open, and when the cartridge 40 is inserted from the lower end of the housing 12, the thermal navel F- is opened from the insertion window 41a.
25 and a guide bar 42 that sandwiches the thermal head 25.
43 is inserted into the cartridge 7 40, and the heating resistor at the lower end of the thermal head 25 comes into contact with the IDF 23. In the illustrated example, the guide bars 42 and 43 are formed into a vertical plate shape to guide the cartridge 40 when it is inserted and removed, and have an arcuate projection at the lower end to guide the winding of the IDF 23. It has become.

FIG. 12 shows the mechanical part of the cartridge 40,
Gears 44 and 45 are formed on the outer surface of the end of the IDF supply roll 22 and the outer surface of the end of the IDF take-up roll 21, respectively. Additionally, racks 46 and 47 are formed on the outer surfaces of the guide bars 42 and 43, respectively. rack 4
6 is formed on the guide bar 42 corresponding to the gear 44 of the IDF supply roll 22, and the rack 47 is formed on the guide bar 42 corresponding to the gear 44 of the IDF supply roll 22.
The guide bar 43 is formed in correspondence with the first gear 45 . These ranks 46, 47 are formed with a length such that they mesh with each gear 44, 45 when the cartridge 40 is inserted or removed, and do not mesh with the gears 44, 45 after the cartridge 40 is completely fitted into the housing 12. . cartridge 40
This is because in the fitted state, it is necessary to rotate the IDF take-up roll 21 and the IDF supply roll 22 together with the movement of the recording unit 2.

In such a configuration, the IDF 23 can be replaced by inserting and removing the cartridge 40, which makes it easy to replace the IDF 23 and to replace it with a new IDF 23 or a chromatic IDF 23. In this operation, when the cartridge 40 is removed from the housing 12 (when the cartridge 40 is pulled downward in FIG. 10), the gear 44 meshes with the rack 46 and the gear 45 meshes with the rack 47. Then, when the cartridge 40 is further pulled in the same direction, the IDF supply roll 22 having the gear 44 rotates clockwise as shown by the arrow, and the IDF take-up roll 21 having the gear 45 rotates counterclockwise as shown by the arrow. do. Since the rotation of each of these rolls 22.21 is in the direction to wind up the IDF 23 onto each roll 22.21, the roll 2
The portion hanging between the rolls 22.21 (this portion hangs between the rolls 22.21 in order to contact the thermal head 25) is wound up on each roll 22.21. Therefore, when the cartridge 40 is pulled out from the housing 12, there is no hanging portion in the IDF 23, making subsequent processing convenient. Next, in order to reinstall the removed cartridge 40 into the housing 12, the cartridge 40 is inserted from the lower end of the housing 12. During this insertion, the gear 44 meshes with the lasso 46. and IDF
As the supply roll 22 rotates counterclockwise, the gear 4
5 engages with the rack 47, and the IDF take-up roll 21 rotates clockwise. These rotation directions are determined by rotating the IDF23
Since the direction is to draw from call 22.21, D23
A sagging portion is formed between the rolls 22 and 21, allowing contact with the thermal head 25 to be made without any problem.

In the above embodiment, gears were provided on both the IDF supply roll 22 and the IDF take-up roll 21, but they may be provided on only one of the rolls, and in this case, the rack may also be provided on either one. , the structure can be simplified.

13 and 14 show another example of the cartridge 40, in which the cartridge 40 includes a TDF supply supply system 22 and an ID
The F take-up roll 21 is suspended over a frame 41. That is, the drive rollers 13 and 14 are installed in the housing 12 of the recording section 2 in advance, and the I

It is positioned by these plates 50,51. Among these, the support plate 50 pivotally supports the drive rollers 13, 14 and the torque transmission section 20, and the

The cartridge 40 is attached to a fixed position within the housing 12 by engagement with the positioning pin 52 and the output shaft of the torque transmitting section 20.

In addition to this configuration, a force I/ridge fixing means 53 is provided on the inner surface of the longitudinal end (right end in the illustrated example) of the housing 12.

1 is pressed in the direction of the torque transmission section 20 and also presses the frame 41 in the direction of the support plate 51, thereby preventing the support plate 51 from coming off the positioning pin 52.

As a result, since the cartridge 40 is firmly fixed at a fixed position, the torque transmission section 2
The cartridge 40 is moved to the support plate 5 by the rotational force of 0.
The IDF 23 can be wound smoothly and reliably without coming off from 0 or 5I. Furthermore, the cartridge 40 will not come off due to shock or vibration during transportation or the like. In the illustrated example, a leaf spring bent into a "C" shape is used as the car 1 to rigid fixing means 53, and the bent piece presses the outer surface of the frame 41 of the cartridge 40, but the invention is not limited to this. , other members such as a rubber plate may also be used.

FIGS. 15 and 16 show still another example of the cartridge 40, in which the IDF supply roll 22 and the IDF take-up roll 21 are pivotally supported by a cassette frame 48.

The entire cartridge 40 is removably inserted into a unit frame 49.

The unit frame 49 can be attached using appropriate fastening means such as hooks (

For this reason, the unit frame 49 has two wooden drive rollers 13 and 14 on its lower end, on which a belt 18 is passed, and is connected to one of the drive rollers 13 via a belt (not shown) for rotation. It has a transmission piece 54. The transmission piece 54 is the winding roll 21 of the cartridge 40
The IDF 23 is inserted into one end surface and engaged with the take-up roll 21 to transmit the rotation of the drive rollers 13 and 14 to the take-up roll 21, thereby winding the IDF 23.

Further, an arc-shaped guide plate 56 is provided in the unit frame 49 to support the cartridge lithium 40 from below, so that the cartridge 40 can be stably held. One side end of the unit frame 49 is open, and the cartridge 40 is inserted from this side end to be attached or removed. This car 1~ritsuji 40
The entire cassette frame 48 is integrally molded from plastic to reduce its weight. One end of the cassette frame 48 extends downward, and a positioning hole 56 is formed in the extended portion. has been done. On the other hand, this positioning hole 56 is provided on the outer surface of the Unino I frame 49.
A positioning pin 55 is provided to be inserted into the unit frame 49, and by inserting this pin, the cartridge 40 is fixed at a fixed position in the unit frame 49. The upper and lower central portions of the cassette frame 48 of the cartridge 40 are opened, and a thermal head (not shown) is inserted into the cassette frame 48 to make contact with the IDF 23. A pin 57 is inserted into one end surface of the IDF supply roll 22 to pivotally support the TDF supply roll 22. When the cartridge 40 is installed in this manner, it is necessary to prevent the cartridge 40 from accidentally falling off, and the cartridge 40 and the unit frame 49 are provided with a retaining member 58 that engages with the cartridge 40 and the unit frame 49. In this embodiment, the unit frame 49 includes a retaining plate 58b that protrudes from the upper part of the unit frame 49 into the frame 49, and an engaging protrusion 58a that protrudes from the upper end surface of the cassette frame 48 of the cartridge 40. here,
The retaining protrusion 58a can engage with one end surface of the retaining plate 58b when the cartridge 1-ridge 40 is installed, and can engage with the lower surface of the retaining plates 1 to 58b when the cartridge 40 is inserted into the unit frame 49. It is formed at a height that allows it to pass through contact. Therefore, the engagement protrusion 58a does not become a hindrance when the cartridge 40 is inserted, and after the cartridge 40 is installed, it engages with the engagement plate 1* to prevent the cartridge 40 from being accidentally dropped. Note that the retaining member 58 may be a hook or the like that can be mutually engaged and detached. On the other hand, when removing the cartridge 40, it is necessary to release the engagement between the retention plate 1-58b and the engagement protrusion 58a, and a release mechanism 59 is provided for this purpose. In this embodiment, the cassette frame 48 of the cartridge 40 is molded of plastic, and since that portion is recessed by appropriate pressure, the release mechanism utilizes this property. That is, the release mechanism 59 has a structure that presses the vicinity of the engagement protrusion 58a to push down the retention protrusion 58a, and does not require a dedicated release member. The engaging protrusion 58 is used to provide a guideline for the pressing position, to prevent slippage during pressing, and to apply a sliding force in the removal direction to the cartridge 40.

17 and 18 show an embodiment in which a guide member 60 is provided for the IDF 23 passing through the thermal head 25. The guide member 60 is provided so as to surround the thermal head 25, and is screwed into the housing 12. It is fixed by welding etc. The guide member 60 has a first guide surface 6I located on the supply side of the IDF 23 and a second guide surface 62 located on the take-up side of the IDF 23, and the thermal head 25 has these guide surfaces 61. is inserted into a closed cross-section passageway formed by 62. FIG. 35 shows a state in which the thermal head 25 is inserted into the guide member 60, and the guide member 60 has flange portions 63 connected to the housing 12 formed on both sides. Also, mounting grooves 64 for the thermal head 25, which are sandwiched between the control board 27 and the thermal head fixing plate 29 and integrated therewith, are formed on both sides. This mounting groove 64 is connected to the integrated thermal head 25, control board 27, and thermal head fixing plate 2.
The thermal head 25 is firmly fixed within the guide member 60 by insertion thereof. When the thermal head 25 is scanned in this inserted state, the mounting groove 64 supports the thermal head 25 in the front-back direction in the scanning direction, and it does not move in the scanning direction, so there is no wobbling of the thermal head 25. , it becomes possible to transfer images with stable image quality. Note that the mounting groove 64 is open in the insertion direction (up and down direction) of the thermal head 25, and can move up and down freely against the pressure applied to the thermal throat 25 during transfer, so the pressure can be applied smoothly. be able to.

The IDF 23 comes into sliding contact with the first guide surface 61 and the second guide surface 62 of the guide member 60 when recording an image on the recording paper B. These guide surfaces 61, 62 are formed in such a shape and position that the IDF 23 is smoothly guided. The first guide surface 61 is an ID supplied from the IDE supply roll 22.
It guides F23 to the thermal head 25. I from this first guide surface 61 to the thermal head 25
When supplying the DF 23, it is preferable that the IDF 23 be given an appropriate tension and move smoothly. For this reason, as shown in FIG. 20, the first guide surface 61 is provided with a lower end surface view α of the thermal head 25 so that the lower end edge is at a higher position than the lower end surface of the thermal head 25, and The angle γ between the normal to the contact point of the IDF 23 and the horizontal axis is set to a predetermined value. These α
and γ are appropriately determined by jX depending on the type and thickness of the base material of the IDF 23. For example, if the base material of the IDF is
．． In the case of a 6 μm thick polyester film, α can be set to approximately 1.5 mm and r to approximately 41°. Further, it is preferable that the portion (lower edge) where the first guide surface 61 contacts the IDF 23 has a shape in which the center portion is slightly raised downward compared to both ends in the width direction. FIG. 21 shows the shape of the lower edge 61a of the first guide surface 61. A straight line connecting both ends of the lower edge 61a is defined as the X axis. When an axis is formed, the lower end edge 61a of the first guide surface 61 has the lowest minimum value at the center where it intersects with the X axis, and both sides of this minimum value form a quadratic curve that rises with the same curvature. By adopting such a shape, when the IDF 23 contacts the lower edge 61a of the first guide surface 61, tension is applied to both sides in one direction, eliminating the occurrence of wrinkles, skew, etc., and ensuring smooth feeding. It will be done. In addition, the minimum value is 0.15i when IDF23 has the above-mentioned base material and thickness.
A range of ++i±50 μm is suitable. Next, IDF2
The second guide surface 62 provided on the winding side of the paper I is fixed to the recording paper B by the heat generated by the thermal head 25.
It is provided to smoothly peel off the DF23. In this case, it is preferable from the viewpoint of transfer density to keep the IDF 23 in contact with the recording paper B while the wax in the IDF 23 solidifies (the cooling time described above is about 0.3 seconds) and then peel it off. It is preferable to perform the above steps simultaneously in the 1) direction of the recording paper B. The second guide surface 62 is formed taking such points into consideration, and as shown in FIG. The height β of the lower end surface of the second guide surface 62 from the height β is appropriately selected. These values change depending on the material of the IDF23, etc. For example, in the above case, δ is approximately 3.5 fins and β is 0.
．． 2+i+u or less is preferable. Furthermore, the lower end surface of the second guide surface 62 that comes into contact with the IDF 23 is formed in a horizontal straight line. Thereby, the IDF 23 after transfer is smoothly peeled off from the recording paper B by the second guide surface 62, and a clear and stable image can be formed.

Note that the first guide surface 61 and the second guide surface 62 as described above, the guide bar 2 shown in FIGS. 4 and 5
It can also be obtained by forming 4 and 26 into the shapes and dimensions described above and providing them at predetermined positions.

FIG. 22 shows a cross-sectional view of the internal structure of the reading unit 3. The reading unit 3 can read the document when it is located directly below the recording unit 2 (read mode). Information on the document is read by scanning over A. The reading unit 3 includes an LED array 71 as a light source that irradiates the document surface with light, a SELFOC lens 72 that forms an image of the document surface irradiated by the LED array 71 on a predetermined position, and a SELFOC lens 72 that uses light from the SELFOC lens 72. A contact type image sensor 73 that photoelectrically converts images, and a roller 7 that rolls on the document surface and is connected to an encoder, etc.
4, a memory 75 that stores image information read by the image sensor 73 (the same memory as the memory 28 in the recording section 2), a control section 76 that controls the address of the image information to the memory 75 and the timing of data transfer, It is comprised of a position detector (not shown) that outputs an electric signal according to the rotation of the roller 74, and a housing 78 that houses the above-mentioned members.

As shown in FIG. 23, the lower surface of the casing 78 that contacts the original A is curved downward, and a substantially central portion forms a planar contact surface 78a that comes into close contact with the original A. and contact surface 7
7 is provided with a transparent reading window 79 that transmits light from the LED array 71 and receives reflected light from the document A. This housing 78 is entirely formed by integral molding of transparent resin. Transparent resin absorbs 90% of visible light.
% or more of transmittance is used.

A light shielding film 77 is formed on the inner surface of the casing 78 over the entire portion except for the substantially central portion of the contact surface 78a.

The portion where the light shielding film 77 is not formed becomes a reading window 79, and the reading window 79 is formed by providing the light shielding film 77 on the housing 78 after integrally molding the housing 78. There is. The light blocking film 77 is formed to have a light transmittance close to 0%, and blocks light from areas other than the reading window 79, thereby blocking light from other than the reading window 79.
Since no light enters into the image sensor 8, reading of incorrect image information can be prevented. The light blocking film 77 is made of a material that has a light blocking ability and is formed in advance into the same shape as the casing 78 so that the reading window 79 is open. Furthermore, the outer surface or inner surface of the casing 78, or even both surfaces thereof, may be formed by coating a black paint or the like that absorbs light in the visible region. Alternatively, a metal film such as aluminum or silver may be deposited on the inner surface of the housing 78 to reflect light. In this way, the entire housing 78 is integrally molded with transparent resin, and the portion excluding the reading window 79 is coated with the light shielding film 7.
Since the reading window 79 comes into contact with the original surface on the same surface by covering the reading window 79, there is no catching on the original during reading scanning, and there is no problem such as damage to the original or inability to read the original. In addition, since the contact surface 78a with the original A is flat, even if dust adheres to it, it can be easily removed, so that dust is not read as image information.
Image information can be read with high precision. Furthermore, since the casing 78 is integrally molded from transparent plastic, the casing 78 can be molded in large quantities with high precision.

FIG. 24 shows a case where the reading section 3 is configured separately from the recording section 2, and each member inside the casing 78 is the same as that in FIG. 22, so a description thereof will be omitted. is made of transparent resin, and the portions other than the reading window 79 (not shown) are covered with a light blocking film. Also, in this example, the memory 75
is removable from the side of the housing 75, and after reading the document, the memory 75 can be removed and attached to a suitable playback device (not shown) to display the image information.
Alternatively, it can be attached to a recording device (not shown) and transferred onto recording paper. In addition, the reading section 3 can be connected to a display device (not shown) such as a CRT for display,
You can also connect it to a facsimile machine and transfer it to the other party.

FIG. 25 shows the internal mechanism of the reading section 3. As shown in FIG. 26, the reading unit 3 is placed over the original A at a distance
X=1++m) When scanning, the image information G on the document is newly stored while erasing the previous image information stored in the memory. In FIG. 26, the broken line F indicates the image input position, and the solid line E indicates the front edge of the reading section in the scanning direction. The internal configuration of the reading section 3 includes a reader-like detection section 81 that detects whether the copying apparatus 1 is in a read mode (as shown in the second figure) or a write mode (as shown in the third figure), and a read/write button. 5 (Fig. 1) is pressed, the switch 83 closes, the AND gate 82 takes the logical product of the output signal of the reader/writer detection section 81 and the signal of the switch 83, and the signal from the ant game 182 starts. A start signal generation circuit 84 that generates a signal, an encoder 85 connected to the roller 74 (FIG. 22), and an AND gate that takes the logical product of the start signal from the start signal generation circuit 84 and the pulse signal from the encoder 85. 86, a distance count circuit 87 that measures the moving distance X of the reading section 3 based on the pulse from the AND gate 86 and outputs a drive pulse generation signal, and a distance count circuit B7.
An image sensor drive pulse generation circuit 88 that generates drive pulses for the image sensor 89 based on signals from the image sensor 89.
, an image sensor 89 that photoelectrically converts and reads the reflected light from the original, a z-value conversion circuit 92 that binarizes the video signal from the image sensor 89, and a drive pulse synchronized with the drive pulse from the image sensor drive pulse generation circuit 88. For example, the serial/parallel register 90 converts the signal output from the binarization circuit 92 into parallel data, and the drive pulse from the image sensor drive pulse generation circuit 88 is
a frequency divider circuit 91 that divides the frequency into 8 (the frequency division ratio is determined by how many bits are read per 1 dragon); an address generation counter 93 that counts the output pulses of the frequency divider circuit 91 and determines the address for the memory 94; , and a memory 94 for storing data output from the serial/parallel register 90 at an address designated by an address generation counter 93.

In the above configuration, when the reading unit 3 of the copying machine (Readmo F) is placed on the document and the read/write button 5 is pressed to turn on the switch 83, the league-like detection unit 8
The AND of the signal 1 and the signal of switch 83 is ant game 1.
- The start signal generation circuit 84 generates a start signal based on the output signal of the AND gate 84. On the other hand, the encoder 85 orders a pulse signal corresponding to the rotation of the roller 74, and an AND gate 86 performs a logical product between the pulse signal of the encoder 85 and the start signal of the start signal generation circuit 84.
A distance counting circuit 87 counts the distance traveled based on the pulses. The distance counting circuit 87 does not output a pulse signal to the image sensor drive pulse generation circuit 88 until the moving distance reaches a predetermined value X (for example, Inm), and only generates an image sensor drive pulse when the distance X reaches a predetermined value. Output to circuit 88. That is, the image sensor 89 does not start reading until the moving distance reaches a predetermined value, and the image information read last time is stored in the memory 94 while the moving distance reaches the predetermined value. Therefore, even in the case of an erroneous operation, by stopping the operation while moving a distance less than a predetermined value, the previous image information is stored in the memory 94 and can be reproduced. In this case, the operation can be stopped by stopping the movement of the device or by releasing the pressure on the read/write button 5. Next, after the moving distance reaches a predetermined value X, the distance counting circuit 8
7 sequentially outputs the image sensor drive pulse signal.

The video signal read by the image sensor 89 is binarized by a binarization circuit 92, and then converted into parallel data by a serial/parallel register 90 and output to a memory 94. In this case, the image sensor 89
A drive pulse is output from the image sensor drive pulse generation circuit 88 to the frequency dividing circuit 91 in synchronization with the drive pulse to
The frequency dividing circuit 91 counts and amplifies the address generation counter 93 every time it counts 8 drive pulses. Each time the counter 93 counts up, it supplies address data to the memory 94, whereby an 8-bit image data synchronized with the designated address/frequency division pulse of the frequency division circuit 91 is stored.

According to such a configuration, reading of the image sensor 89 is prohibited when the amount of movement is less than a predetermined value, and since the previous image data is stored in the memory 94, erasure of image data due to erroneous operation can be prevented. can. Although the above configuration has been described with respect to the reading section, the distance counting circuit 87 may also be incorporated into the recording section 2, and the thermal head 25 may be started and driven by a signal from this circuit 87. This also prevents data from being erased due to erroneous operations during recording.

FIG. 27 is a block diagram of a signal processing means provided between the image sensor 89 and the binarization circuit 92, which inverts and amplifies the video signal from the image sensor 89 based on a predetermined power supply voltage and outputs it.

1. The binarization circuit 92 is an inverting amplifier circuit 105
The video signal from the integrating circuit 101 is compared with the output signal from the integrating circuit 101 and outputted. Figure 28 shows integration circuit 1
01 and a circuit diagram of a portion including a binarization circuit 92,
Integrating circuit 101 has a comparator 107 that captures high frequency components of the video signal from inverting amplifier circuit 105.

On the other hand, the binarization circuit 92 includes a voltage dividing circuit 95 connected to the integrating circuit 101 and a comparator 102 connected to the voltage dividing circuit 95. The voltage dividing circuit 95 has a resistor r,
. The comparator 102 binarizes the video signal from the inverting amplifier circuit 105 based on this binarized reference signal and outputs it as a pulse signal consisting of an lligh signal and a low signal. Here, the voltage dividing circuit 9
Among the resistors r1, 2, and r3 of 5, r, which is connected in series to the comparator 102, is a themistor that detects the environmental temperature and changes its resistance value according to the temperature, so that it can be used even if there is a fluctuation in the environmental temperature. Always maintain a constant partial pressure. That is, the thermistor rl serves as a partial pressure control means for temperature compensating so that the partial pressure in the voltage dividing circuit 95 does not fluctuate depending on the environmental temperature, and thereby always outputs the threshold level as a value within a certain range. be able to. Since the comparator 102 performs binarization based on a fixed threshold level in this way, it is possible to reproduce an image with the same density as the image information of the original. FIG. 29 is a timing chart showing the operation based on the above configuration. The video signal 1) of the image sensor 89 that has been inverted and amplified by the inverting amplifier circuit 105 and the integrating circuit 101
After being processed by the voltage dividing circuit 95, the threshold level VT, . . . is compared with the threshold level VT, . During this binarization, when the threshold level V T I+ is low for the video (g) H, a Low signal (0) is output, and when it is high, an Illight signal (1) is output. This is the threshold level when a fixed resistor is used as the resistance r of the voltage divider circuit 95.If the environmental temperature rises (e.g. 20°C) in the same environment, the resistance value of the fixed resistor of the voltage divider circuit 95 increases. However, when the thermistor r1 is used, the resistance value changes as the temperature rises, so the threshold VTH remains constant. Therefore, the 2 The digitized signal J is output with the same density as the image information.

Figure 30 shows sensitivity of 90V/j! The internal mechanism of a reading section using an image sensor 100 made of a high-sensitivity COD such as x-sec is shown, and FIG. 31 shows its circuit diagram. Here, sensitivity 90■/β8・sec means the amount of light of 1βX
This means that an output of 90V can be obtained by irradiating for a second. Since such a highly sensitive image sensor 89 has a sharp response to light, it responds to a slight change in the amount of reflected light from the original, and the amount of exposure increases.

If this exposure amount increases, a large time delay will occur in the integration process, and a discrepancy will occur between the binarization reference symbol generated after the integration process and the video signal that has not been integrated, which will impede the binarization process. Therefore, it is necessary to correct this so that it is read as correct document information. Therefore, as shown in FIG. 30, the image sensor 89, the inverting amplifier circuit 105,
In addition to the integration circuit 101 and the binarization circuit 92, this circuit 10 includes a signal processing control circuit 103 that electrically cants the output of the image sensor 89 when it exceeds a predetermined value.
An AND gate 104 is provided which performs a logical AND operation between the signal from 3 and the binarized signal from the binarization circuit 92 and outputs the result. As shown in FIG. 13, the inverting amplifier circuit 105 has an amplifier 106 that inverts and amplifies the video signal from the image sensor 89 based on the voltage of the voltage VD1), and the inverting amplified video signal is sent to the integrating circuit +01. .Binarization circuit 9
2 and the signal processing control circuit 103. The integrating circuit 10 cuts high frequency components of the video signal amplified by the inverting amplifier circuit 105, and has a comparator 107 for this purpose. The binarization circuit 92 has a comparator 102 and a voltage dividing circuit 95, and compares the output signal from the integration circuit 101 with the video signal from the inverting amplifier circuit 105 to divide them into two signals. This binarization circuit 92
Then, when the output signal of the integrating circuit 101 is low with respect to the video signal from the inverting amplifier circuit 105, a Low signal (0) is generated.
is output, and when it is high, outputs J (i g h signal (1)). The binarized signal binarized by this binarization circuit 92 is output to ant game) 104. On the other hand, the signal processing control circuit 103 has a determiner 109 to which the video signal amplified by the inverting amplifier circuit 105 is input. Also, a resistor r that divides the power supply voltage VDD and provides a constant base half value voltage.
4, rs, and this reference value voltage is input to the determiner 109. A determiner 109 compares these signals and outputs a Low signal if the inverted and amplified video signal is equal to or higher than the reference voltage.

The AND gate 104 connects this LOW signal to the binarization circuit 92.
The logical product of the binarized signals from is taken and output.

The operation of the above configuration will be explained based on the timing chart of FIG. 32. The integral value signal I from the integrating circuit 101 is generated with a time delay with respect to the video signal H of the image sensor 89 which is inverted and amplified by the inverting amplifier circuit 105. Here, the H a portion of the video signal H has a saturated output that is 3 to 4 times the saturated output of the image sensor (for example, saturated output voltage/V), and is 3 to 4 times the amount of light normally received from the original. This is the part where twice as much light is incident. In other words, it is a portion that receives reflected light from a gap that is not in close contact with the original. The binarization circuit 92 compares the video signal H and the integral value signal I, and outputs a Low signal (0
), and when H<I, outputs a High signal (1) and converts it into a binarized pulse signal J. Also,
The video signal H from the inverting amplifier circuit 105 is input to the determiner 109 of the signal processing control circuit 103. Judgment device 109
Then, the reference value voltage K is input from the resistors r4 and rs, and when the video signal Ha is higher than the reference value voltage (Ha part)
Then, a LOW signal is output to the AND gate 104.

The AND gate 104 connects this Low signal to the binarization circuit 9.
2 and the binary signal J from 2 is taken. The supersaturated portion H output from the image sensor 89 by this logical product
a is canted. That is, a signal caused by reflected light based on light that has entered through a gap with the original is deleted, and an accurate signal that matches the image information of the original can be output to the memory. This eliminates the possibility of reading erroneous signals due to light entering through the gap, making it possible to reproduce a high-quality reproduced image.

FIGS. 33 to 36 show an embodiment of a reading unit in which it is possible to specify a reading area of a document, including a reading unit 200 that reads image information of the document, and a reading unit that controls reading of the reading unit 200. A control means 201, a position detector 202 for detecting a reading position, a memory 203 in which image information read by the reading means 200 is stored, and a reading area specifying means 210 for specifying a reading area to be read by the reading means 200. We are prepared. The reading unit 200 reads the original by receiving reflected light from the original A and photoelectrically converting it into an image signal. It has a light source and an image sensor 206 such as a CCD. The reading control means 201 controls the reading means 200, and includes a central control circuit (CPU) 204, an image sensor driving circuit 205, etc. as shown in FIG.

The position detector 202 detects the reading position when the reading unit is moved in the sub-scanning direction by hand.
For example, it includes an encoder 85, a distance counting circuit 87, etc. as shown in FIG. Next, the reading area specifying means 210 specifies the area to be read by the reading means 200 in the main scanning direction. Image sensor 2 of reading means 200
06. A large number of light sources are arranged long in the main scanning direction,
When only the area reading unit 200 is driven in accordance with the reading width of the document, the reading area specifying unit 210 enables the specification. Therefore, since it is necessary to correspond to the reading areas of a wide variety of documents, it is preferable that the reading area specifying means 210 be manually specified by an operator. In this embodiment, as shown in FIGS. 35 and 36, the reading area specifying means 210 includes a scale 21) provided in the main scanning direction for reading, and a linear encoder 213 that moves in the length direction of the scale 21). , slide knob 2 for sliding the linear encoder 213
14. The scale 21) has graduations 212 such as slits or barcodes formed at predetermined intervals. The linear encoder 213 moves this scale 21) in the length direction, and when it is stopped at a predetermined position, the stopped position is measured by the number of passages of the scale 212, and the reading control means 21
1 is output. The reading control means 201 determines that the area from the slide start end to the stop position is the reading area in the main scanning direction. Thereby, the reading control means 201 drives only the reading means 200 within the designated area, and controls the reading means 200 outside the designated area from driving. Then, the image information read in the designated area is sequentially stored in the memory 203 based on the position information from the position detector 202. With such a configuration, when the reading width of the document is shorter than the reading means 200, only the reading means 200 can be driven for the necessary length, so power can be reduced, and
It is possible to extend the life of components such as light sources and image sensors. FIG. 35 shows an example of the internal structure of the reading section 3 in which the reading area specification 210 of this embodiment is installed, and includes a light source 207 (LED array) that irradiates light onto the original A and a light source that emits light reflected from the original. Selfoc lens 208 to form an image, and C
A reading means 200 is constituted by an image sensor 206 that reads a formed image formed by a CD array. Further, the position detector 202, the reading control means 201, and the memory 203 are installed in the housing 222 by the roller 220 that rolls on the document A as it moves in the sub-scanning direction, and by the encoder 221 connected to this roller 220 by a belt. It is arranged in a predetermined position. The reading area specifying means 210 is provided on the front side of a housing 222 of this reading section, a linear encoder 213 and a scale 21) are placed inside the housing 222, and a slide knob 214 is placed on the outer surface of the housing 222. ing.

With such a structure, the reading area can be designated by sliding the slide knob 214 along the outer surface of the housing 222. In this case, a mark such as a dragon may be printed on the outer surface of the housing 222 to indicate the amount of slide of the slide knob 214. In addition, in the illustrated example,
At the sliding start end of the slide knob 214 and the linear encoder 213 (left end side in FIG. 36), the measured value of the linear encoder 213 is reset to "0", and in this state, the entire area in the main scanning direction becomes the reading area.

FIG. 37 is a sectional view of the reading section 3 having another reading area specifying means 210, and FIG. 38 is a perspective view thereof.
A viewing window 215 made of a transparent member is formed on the entire surface. The viewing window 215 is provided so that the operator can silently view the original A, and the operator can visually check the reading area of the original A in the main scanning direction through the viewing window 215. On the other hand, an LED array 207 is used as a light source of the reading means 200, and this LED array 2
The LED array 207 is provided so that after the light emitted from the light source 07 illuminates the document, a portion of the light is reflected on the viewing window 215. In the figure, reference numeral 223 denotes a reading window through which light emitted from the LED array 207 and reflected from the original A passes and enters the image sensor 206.

The lighting of the LED array 207 is performed by an LED drive circuit 224 as shown in FIG.
5.

The LIE D drive circuit 22a has a switch (not shown) that sequentially lights up the light emitting diodes of the IE D array from one end to the other end in the main scanning direction.
The C,PU 204 controls this switch in order to designate the number of light emitting diodes to be lit. Such C P
The number of lights to be lit by U2O5 is specified by the operator using the operating member 225 in 1,000 scans. In the illustrated example,
The operation member 225 is operated by an area designation switch 225 provided on the outer surface of the housing 222 as shown in FIG. The driving of the circuit 224 is continued, whereby the LED array 207 is sequentially lit from one end (for example, the left end) to the other end (for example, the right end) in the main scanning direction. On the other hand, when the pressure on the area designation switch 225 is released, the LED drive circuit 224 stops driving, and the LED array 207 stops lighting any further. In the illustrated example, the reading area is designated by making the lighting length of the LED array 207 match the reading width of the document. Therefore, the CPU 205 converts the number of LED arrays 207 turned on by the area designation switch 225 into the length of the reading area, and controls the LED drive circuit 224 to turn on the LED arrays 207 during the reading operation. It looks like this. As a result, the specified reading area is retained until it is cleared.

Note that when specifying the reading area by pressing the area specifying switch 225, a mark 226 may be formed on the outer surface of the casing 222 near the viewing window 215 to serve as a guide for specifying.

The display of the maximum width and the minimum width is performed by the controller 129 to check and display the images of the image information stored in the memo January 28. In this case, the display may be performed as an absolute value for the maximum and minimum values, or as a percentage value with the maximum value being 100, or an LED array may be displayed by lighting up corresponding to the answer.

Note that in the above configuration, the recording device 1) 0 is connected by the code 1) 8, but the image information read by the reading device 1) 0 is stored in an external storage medium such as a magnetic card, and the recording device 120 uses this code. It may also be recorded using a storage medium, thereby eliminating the need for a code. Further, the display means can be similarly applied to a copying machine in which a recording section and a reading section are integrated as shown in FIG. 1, and in this case, the display means is preferably provided on the outer surface of the recording section.

FIG. 42 shows a hand-driven copying device 140 in which a recording mechanism and a reading mechanism are incorporated in a negative housing 141. Since this copying device 140 houses the reading device shown in FIG. 40 and the recording device shown in FIG. 41 in the same housing 141, the same elements as those shown in FIGS. It's a shame.

In this case, the recording mechanism and the reading mechanism are driven by using a drive unit 142 in common, and a changeover switch 143 between the reading mode and the recording mode is used. In addition, in the case of reading mode -, throat case 1
24 is retracted into the housing 141 by a solenoid (not shown), thereby avoiding contact between the IDF 125 and the original. On the other hand, in the recorder-1, the solenoid is released and the head case 124 is lowered by the spring force, and the rDF] 25 and the recorder B are brought into contact. In addition,

In the recording mode, the display means 145 displays (1) the result of comparing the width of the recording body B with the width of the image information in the memory 128 in the main scanning direction, or (2) displays the width of the recording body B.

Next, the operation (2) will be explained according to the flowchart of FIG. In the recording mode, the image sensor 1) 3 reads the inside of the recording medium B, and the information is input to the reading processing section 1) 5 one by one, and then output to the controller 1-roller 129. The coin controller 129 reads out the image information stored in the memory 128 and controls the thermal conductor 121 to generate heat. The size signal (Lp) of recording medium B from part 1) 5 is compared with the size signal (Lp) of 1). As a result, if L m > I, p, that is, the memory 12
If the image information No. 8 is larger than the width of recording body B, it is displayed by lighting or blinking a lamp (not shown) (an audio display using a buzzer may also be used).

This display allows the operator to stop recording and prepare a recording medium B of an appropriate size according to the image information, so that error-free transfer can be performed. On the other hand, Lm≦

The operator can continue transcription.

The operation of ■ is the one that omits the comparison in the operation of ■, and is read by the image sensor 1) and controller 1.
The size signal Lp of the width of the recording medium inputted to 29 is directly displayed numerically or on a number line on a display (not shown) of display means 145. The operator can select the recording medium B of the optimum size based on this display.

FIG. 44 shows another display method on the display device 145. In this case, the image information in the memory 128 is displayed on the display 147 or 148. FIG. 4A shows that the entire image information in the memory 128 is displayed simultaneously, and this is done by turning on the switch 144. For example, if the maximum input capacity in the main scanning direction is 20 characters per line, and the memory stores 40 lines in the sub-scanning direction, the left half of the 1st to 5th lines will be 10 characters are displayed on each line, 6th to 10th lines display all characters on each line, 1) to 15th lines display 15 characters on each line on the right half, and 16th to 20th lines display 1 in the center.
Each zero character is displayed on the display 147. By visually recognizing these display patterns, the operator can know the content and size of the image information stored in the memory, thereby enabling error-free transcription. In the same figure (bl, the first display section 148a displays the size of each row in a straight line, and the second display section 148a displays the corresponding number of rows numerically.

148b, it is possible to sequentially grasp the image content in the memory.

FIG. 45 shows a separate hand-driven copying device 140 in which the recording mechanism and reading mechanism are incorporated in the same housing 141. This embodiment is a copying apparatus that simultaneously performs an image reading operation and recording of the read image information during one scan.

The reading mechanism includes a light source 1) 1, a lens array 1) 2, and a CC
The image sensor 1) 3 is provided with an image sensor 1) 3 such as a D array, and the image sensor 1) 3 reads image information of the document A using reflected light from a reading window 1) 7 formed on the lower end surface of the housing 141. The image information read by the image sensor 1) 3 is input to the stripe controller 129, and the controller 12
9 directly to the recording mechanism. The recording mechanism includes a paper roll 157 on which direct thermal paper 156 is wound, and a thermal head 121 that directly heats the thermal paper 156 to record image information. Controls heat generation operation. here,
A hasoflu 149 and a pressure pan 150 are provided facing each other on the supply path of the direct thermal paper 156.
56, an image is recorded when it passes between these. For this reason, the thermal head 121 is
The pressure vane 150 is provided at a portion facing the pressure vane 150. Note that there is a paper drawer window 15 at the bottom of the back of the housing 141.
1 is formed, and the direct thermal paper 147 after recording can be led out from this paper drawer window 151. In the above configuration, the thermal paper 15 directly pulled out from the paper drawer window 151
If you scan the entire document in the direction of the arrow while pressing the pull-out end of 6 with your finger, the image on the document will be transferred to the image sensor 1) 3.
At the same time, the read image information is output to the controller 129, which causes the thermal head 121 to generate heat and record directly onto the thermal paper 156. Note that the above operations are performed by the battery 142 provided within the housing 141.

In such a configuration, a half mirror 152 is provided on the reading optical path of the light reflected from the document, and a mirror 153 is provided on the optical path of the light reflected from the half mirror 152. The half mirror 152 has the property of allowing most of the reflected light from the original A to pass through, but reflecting a portion of it, and the reflected light reflected from the half mirror 152 is transmitted to the mirror 1.
53 leads upward along the side surface of the housing 141. That is, the half mirror 152 and the mirror 153 constitute a light guide path that takes out a part of the reflected light from the original A to the outside of the reading optical path. A check window 154 made of a transparent member is provided at the output end of this light guide path, that is, at the upper end surface of the housing 141. The check window 154 is provided along the main scanning direction of the housing 141 as shown in FIG. 46, and the operator can visually confirm the image of the document A by looking through the check window 154. Therefore, before starting the copying operation, the content of the image on document A can be visually checked from this check window 154, making it possible to check the image to be copied and place the cent accurately at the image position, thereby ensuring error-free copying. It can be carried out. In this embodiment, a magnifying lens 155 is provided at one end of the check window 154.
It is possible to slide along. Magnifying lens 155
is provided with a size that enlarges at least one character of the image information, and by enlarging the image of the document through the enlarging lens 155, it becomes easy to visually recognize it.

In this case, since the magnifying lens 155 is slidable, it can be adjusted to match the original image, but the magnifying lens 155 may be fixed, or the magnifying lens 155 may be omitted. . FIG. 47 shows an application example in which the magnifying lens 155 is provided at both ends of the check window 154.The magnifying lens 155 is not limited to this, but it is also possible to provide the magnifying lens at the center of the check window 154, and the entire check window 154 is may be composed of a lens with a predetermined magnification.

FIG. 48 shows an application example of the embodiment having a light guide path and a check window 154, in which a mirror 159 provided on the reading optical path is pivotally supported at its lower end to swing and move forward and backward with respect to the reading optical path. It has become. The entire surface of the mirror 159 is a completely reflective surface, and while it does not block the reflected light from the document A when it is retracted from the reading optical path 156, it does not block all of the reflected light when it enters the reading optical path. It acts to reflect and lead to the check window 154. The advancing operation of the mirror 159 can be switched using a push button (not shown) or the like. In such a configuration, when it is necessary to check the image content of the document A before copying or when it is necessary to check the completion of copying after copying, the mirror 159 is moved onto the reading optical path.
While these images can be visually recognized, when the mirror 159 is retracted from the reading optical path, there is no absorption or scattering of reflected light, so there is an advantage that the image can be read accurately.

FIG. 49 shows a hand-driven copying device 160 in which a transfer medium such as direct thermal paper is omitted, and a thermal transfer sheet h171 shown in FIG. 50 is used separately during recording. .

On the other hand, the recording mechanism includes a thermal head 167 facing the opening at the bottom of the housing 161, and a memory 166.
The controller 168 reads out image information from the printer and drives the thermal head 167 to generate heat according to the image information. Note that a drive roller 169 connected to an encoder (not shown) or the like is provided at the lower opening of the housing 161. Furthermore, as shown in FIG. 15, a start button 170 for turning on and off reading and recording operations is provided on the front surface of the housing 160.

As shown in FIG. 50, the thermal transfer seam 71 includes an IDF sheet 172 and a frame 173 stretched around the periphery of the IDF sheet 172. The IDF sheet 172 has an ink-impregnated lower surface, and is placed so that the ink-impregnated surface contacts the recording paper B during recording. Frame body 17
3 is made of a material with appropriate openness, such as cardboard or other thick paper, or a plastic frame.

When such a frame 173 is stretched over the IDF sheet 172, a predetermined tensile force is applied to the IDF sheet 172, so that there are no wrinkles or bends during recording, and good recording without transfer omission is possible. Become.

FIG. 51 shows a recording operation using the copying apparatus 160 and the thermal transfer sheet 171 described above. The thermal transfer sheet 171 is stacked on the recording paper B so as to overlap, and the copying device 160 is placed on the thermal transfer sheet 171. Then, when the copying machine 160 is moved in the direction of the arrow while pressing the start switch 170, the controller 16

5 contacts one of the drive rollers 13 and acts to feed the recording paper B to the roller 236. The roller 236 is in contact with the thermal head 25, and presses the recording paper B against the thermal head 25 to prevent I from being generated due to the heat generated by the thermal head 25.
It acts to ensure transcription of DF23. roller 2
37 contacts the other drive roller 14 and acts to rotate it. The encoder detects the position by the rotation of the drive roller 14 and outputs the detected signal to a controller (not shown), so that the heat generation drive of the thermal head 25 can be controlled in accordance with the supply of the recording paper B. Such a transport roller 235.236.23
7, a handle 238 is removably attached to one side of the base 231, and a plurality of intermediate gears 239 are provided between the rotation axis of the noddle 238 and the rotation axis of the conveyance roller 236. There is. On the other hand, the conveyor rollers 235 and 237 on both sides of the conveyor roller 236
is the rotational force transmission gear 239.240 that meshes with the rotating shaft.
It is connected to the roller 236 by. That is, gears 235 a, 236 a, and 237 a are formed on the rotating shaft of each conveyance roller 235, 236, and 237, respectively, and rotational force transmission gears 239 and 240 are provided between these gears. Of these, the rotational force transmission gear 239 is provided between the gear 235 of the conveyance roller 235 and the gear 236a of the conveyance roller 236, and the rotational force transmission gear 240 is provided between the gear 236a of the conveyance roller 236 and the gear 237a of the conveyance roller 237. is provided in between. These rotational force transmission gears 239, 240 transmit the rotational force of the handle 238 to the transport rollers 235, 236, 237, and
5, 236, and 237 rotate in the same direction and at the same rotational speed to convey the recording paper B. Of these, the conveyance roller 237 on the encoder side (left side) and the thermal head 25 of the recording section 2
A control arm 241 extending vertically upward is attached to the gear 240 located between the lower conveyance roller 236 and the gear 240 . The upper end surface of the control arm 241 abuts the lower end surface of the housing 12 of the recording section 2, and the control arm 241 receives the own weight of the recording section 2 and the pressing force applied to the recording section 2, and the gear 236a
and 237a. moreover,
The rotational shaft of this rotational force transmission gear 240 is connected to the rotational shaft of the conveyance roller 237 on the encoder side by a connecting arm 242. As shown in FIG. 54, the connecting arm 242 is rotatably attached to the rotating shaft of the conveying roller 237, and its rotation causes the rotational force transmission gear 240 to mesh with the gear 236 of the conveying roller 236 below the thermal head 25. and its departure. The rotational force transmission gear 240 is biased in the direction of engagement and disengagement with the gear 236a by a suitable biasing means (not shown) such as a spring.

This pressing force is sufficient for the paper head 25 to press the recording paper B against the conveying roller 236, so that the IDF 23 can perform the transfer properly. If this pressing force is insufficient, or if the recording section 2 is in front of the center as shown in FIG. 53(b),
Due to the biasing force of the biasing means, the rotational force transmission gear 240 is rotated in a direction opposite to the meshing direction with the gear 236a of the conveying roller 236, thereby disengaging the gear 236a. Therefore, the conveyance rollers 236 and 2
37 is disconnected, and the rotational force of the handle 238 is not transmitted to the conveying roller 236. Moreover, this conveyance roller 2
36 is connected to the encoder, and since the encoder signal is not output to the controller, the thermal head 2
5 does not generate heat. As a result, reading of the image information in the memory is stopped and a hold state is entered. Therefore, recording is not performed in a state where the pressing force is insufficient or when the copying machine is applied before the center, and recording is performed only in a predetermined pressing state, so that good transfer is possible and there is no transfer omission.

Rotational force transmission gears 239 and 240 are disposed between the gears 235a and 237a of the conveyor rollers 235 and 237, and the left rotational force transmission gear 240 has a control arm 241 attached to it and is rotated by a spring or the like. It is urged to rotate in the meshing direction. A switch means 252 is provided below this rotational force transmission gear 240. The switch means 252 turns on and off the power of the motor 250 (not shown), and has a switch button 253 that turns on the power when pressed and turns off the power when released. Furthermore, a switch arm 254 corresponding to this switch button 253 is attached to the connecting arm 242. As described above, the connecting arm 242 rotatably supports the rotational force transmission gear 240 with respect to the conveying roller 237. In such a structure, when the rotational force transmission gear 240 is in mesh with the conveyance roller 236 in a recordable state, the switch arm 254 presses the switch button 253 as shown in FIG. 60(a), so the motor 250 is driven. The recording paper is transported. Therefore, good transfer can be performed automatically. On the other hand, due to the urging force of the urging means due to insufficient pressure on the copying device, the rotational force transmission gear 2
40 is disengaged from the conveyance roller 236, the switch arm 254 separates from the switch button 253 as shown in FIG. 60(b), and the switch button 253 stops driving the motor 250. Therefore, careless conveyance and transfer of the recording paper is avoided, and transfer errors and the like can be prevented.

FIG. 61 shows a plan view of a conveyance device 230 that automatically supplies recording paper, and a power switch 255 and a start switch 256 are provided on the right side, and further converts the rotation speed of the motor 250 into the amount of movement of the recording paper. A display window 257 is provided to display the information. Power switch 255 connects power and motor 2
50 and start switch 256.
commands the start of recording. In the above-described configuration, if the rotational force transmission gear 240 is disengaged from meshing even in the start command of the start switch 256, no recording is performed.

FIG. 62 shows an example in which a paper cassette 260 is assembled to the paper transport device 230 as described above. Paper cassette 260
A large number of sheets of recording paper B are stacked and housed, and a feed roller 261 is provided at the feeding end thereof and presses against the uppermost recording paper B. The feed roller 261 is connected to the output shaft 250a of the motor 250 by the heald 262.
is connected to. By using the paper cassette 260 in this way, recording paper can be automatically and continuously fed, so that recording operations for the same content can be performed smoothly and quickly.

Note that the paper conveying device 230 described above can be applied not only to supplying recording paper B but also to supplying original documents.
In this case, the reading section of the copying machine is set.

〔Effect of the invention〕

As explained above, in the present invention, the thermal head is not driven at the beginning of movement on the recording medium and only winds up the ink donor film. Wrinkles, skews, etc. are removed, and the ink donor film is placed under tension before being subjected to transfer. Therefore, deterioration in image quality such as transfer omissions is eliminated.
