The power button 6 is a button for turning the power on and off, and by pressing the read / write button 5 while the power button 6 is on, reading or transfer is possible. The transfer magnification button 8 is a button for selecting the transfer magnification, and the selected magnification is displayed by the magnification display lamp 11. The read / write lamp 7 is turned on when the read / write button 5 is pressed, and is turned off when the pressing is released. The speed lamp 9 displays the scanning speed in the case of the reading operation and the transfer operation. When the scanning speed is within the proper range, for example, it lights in green, and when the scanning speed deviates from the proper range, it is displayed in red, for example. Light. Therefore, the operator can perform proper reading and proper transfer by observing the color of the speed lamp 9 and scanning at a speed at which the speed lamp 9 maintains the green state. The memory lamp 10 displays the readable memory capacity, and within the memory capacity range, for example, green light is lit, and when the memory capacity is exceeded, for example, red light is lit and unreadable. Such a hand-driven transfer device 1 is in a readable state (read mode) in the state shown in FIG.
As shown in FIG. 2, the transfer device 1 is placed on the original A,
By pressing the read / write button 5 in the contact state with the document A and pulling it toward you (sub scanning), the information of the document A is read and the content thereof is stored. On the other hand, as shown in FIG. 3 (a), the transfer arm (write mode) is set when the recording unit 2 and the reading unit 3 are separated by rotating the connecting arm 4 so as to bend the reading unit 3 toward the front side. Become. In this write mode, as shown in FIG. 3 (b), the recording unit 2 is placed on a recording medium such as the recording paper B, and when the read / write button 5 is pressed while the recording paper 2 is in contact with the recording paper B, the memory is stored. It is possible to write the information that has been written.

4 and 5 are a sectional view and a schematic perspective view of the recording unit 2, in which drive rollers 13 and 14 made of rubber or the like are provided in the lower portion of the housing 12. Drive roller 13 and
14 are disposed in front and rear so as to be parallel to each other, and when the recording unit 2 is placed on the recording paper B, at least one of them comes into contact with the recording paper B. When the recording unit 2 is scanned on the recording paper B, the drive rollers 13 and 14 roll on the recording paper B. The drive rollers 13 and 14 are connected to each other by a belt 15, and when one of them rotates, the rotation is transmitted to the other.
Among the drive rollers 13 and 14, the drive roller 13 located forward in the scanning direction is connected to the encoder 17 via the belt 16, and the rotation speed of the drive roller 13, that is,
The moving distance of the recording unit 2 is measured by the encoder 17,
The encoder 17 is adapted to output a position signal according to the moving distance. Further, the drive roller 13 is connected to the rotating shaft 19 via a belt 18. Rotating shaft
A torque transmission unit 20 having a torque limiter function is coaxially provided, and its rotation is transmitted to a winding roll 21 of an ink donor film (hereinafter abbreviated as IDF) 23 via the torque transmission unit 20. The IDF take-up roll 21 is for taking up the IDF 23 from the IDF supply roll 22 which is back tensioned. In this case, the IDF 23 is pulled out from the IDF supply roll 22, passed through the guide bar 24, the thermal head 25, and the guide bar 26, and then wound around the IDF winding roll 21. The thermal head 25 is controlled by the control unit of the control board 27, generates heat according to the image signal read from the memory 28, heats the IDF 23, and melts the ink impregnated in the IDF 23. As a result, the image is transferred onto the recording paper B. In this way, the two drive rollers 13 and 14 are connected to the belt 15
In the structure connected by, the operability becomes good when the recording unit 2 is placed on the recording paper B and the recording paper B is scanned manually. Generally, in the case of manually driven scanning, the housing 12 easily tilts forward and backward in the operation direction (that is, the traveling direction), and either one drive roller 13 or 14 floats up from the recording paper B, but in this case also, the other drive roller 13 Or 14
Rotates while being pressed against the recording paper B. This rotation is belt 15
Is transmitted to the lifted drive roller 13 or 14 to rotate that roller. For example, when the housing 12 is tilted rearward in the traveling direction and the drive roller 13 is lifted up, the drive roller 14 contacts the recording paper B and rotates together with the movement of the recording unit 2. This rotation is transmitted to the drive roller 13 via the belt 15 and the drive roller 13 rotates. Therefore, the encoder 17 and the rotating shaft 19 which are connected to the drive roller 13 by the belts 16 and 18
The rotation is transmitted to the encoder, the moving distance is accurately counted by the encoder 17, and the accurate position signal is output, so that the image is accurately recorded and the rotating shaft is
Since the IDF 23 is reliably wound by the IDF winding roll 21 by the rotation of 19, it is possible to obtain a high-quality image without causing slack or wrinkles on the IDF 23. Furthermore, since the meandering of the recording unit 2 can be prevented 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. Drive
A detection roller 31 of a contact detection means 30 described later is provided on the same line as the axis of 13.

FIG. 6 shows a torque transmission unit 20 that transmits the rotation of the rotary shaft 19 to the IDF winding roll 21, and the first rotary member that rotates coaxially with the rotary shaft 19 that receives the rotation via the belt 18.
A rubber member 20b is fixed to the outer periphery of 20a. Rubber member 20
The b has a plurality of elastically deformable protrusions 20c, and the protrusions 20c are elastically engaged with the inner peripheral surface of the second rotating member 20d located on the outer periphery thereof. The second rotary member 20d is rotationally coupled to the IDF winding roll 21 and performs the same rotary motion. Generally, as the winding diameter of the IDF winding roll 21 increases as the recording progresses, a large torque is required to wind the IDF winding roll 21. Therefore, the first elastic member 20a that rotates together with the rotating shaft 19
The protrusion 20c of the rubber member 20b fixed to the elastic member is elastically deformed according to the rotational torque, and a slip corresponding to the rotational torque occurs between the protrusion 20c and the second rotating member 20d. As a result, the take-up roll 21 is decelerated and its peripheral speed is kept constant. In this way, the ink donor film 23 is wound at a winding speed that accurately corresponds to the moving amount of the recording unit 2, so that even if the speed is changed by a manual drive operation, the moving amount and the peripheral speed of the ink donor film match. Is maintained.

In order to facilitate the exchange of the IDF 23, FIGS. 8 and 9 show that the member including the IDF supply roll 22 and the IDF take-up roll 21 is a cartridge 40 and can be attached to and detached from the housing 12 of the recording unit 2. . The cartridge 40 includes a unit frame 41 that can be fitted to the lower end open portion of the housing 12, and a unit frame 41.
41 has an IDF supply roll 22 and an IDF take-up roll 21 both ends of which are pivotally supported, and two drive rollers 13 and 14 hung on a frame 41. The IDF 23 is pulled out from the IDF supply roll 22. It is designed to be wound around the IDF winding roll 21. The unit frame 41 has an insertion window 41a opened at the upper end surface, and when the cartridge 40 is fitted from the lower end portion of the housing 12, the thermal head 25 and the guide bars 42, 43 for sandwiching the thermal head 25 are inserted from the insertion window 41a. The heating resistor at the lower end of the thermal head 25 is inserted into the cartridge 40 and the IDF2
Contact with 3. In the illustrated example, the guide bars 42 and 43 are formed in a vertical plate shape to guide the insertion / removal of the cartridge 40, and the lower end portion serves as an arc-shaped projection portion to guide the IDF 23 for winding. It has become.

FIG. 7 shows the mechanical part of the cartridge 40,
Gears 44 and 45 are formed on the outer surface of the end portion of the F supply roll 22 and the outer surface of the end portion of the IDF winding roll 21, respectively. Racks 46 and 47 are also formed on the outer surfaces of the guide bars 42 and 43, respectively. Rack 46 is gear 4 of IDF supply roll 22
4 is formed on the guide bar 42, and the rack 47 is formed on the guide bar 43 corresponding to the gear 45 of the IDF winding roll 21. The racks 46 and 47 are formed to have a length that meshes with the gears 44 and 45 when the cartridge 40 is inserted and removed, and does not mesh with the gears 44 and 45 after the cartridge 40 is completely fitted into the housing 12. It ID when the cartridge 40 is installed
This is because it is necessary to rotate the F winding roll 21 and the IDF supply roll 22 together with the movement of the recording unit 2.

With such a configuration, the IDF 23 can be exchanged by inserting / removing the cartridge 40, so that the exchange is easy and the operation of exchanging a new IDF 23 or a chromatic color IDF 23 is simple. In this operation, when the cartridge 40 is pulled out from the housing 12 (when the cartridge 40 is pulled downward in FIG. 7), the gear 44 meshes with the rack 46 and the gear 45 meshes with the rack 47. When the cartridge 40 is further pulled in the same direction, the IDF supply roll 22 having the gear 44 rotates clockwise as indicated by the arrow, and the IDF take-up roll 21 having the gear 45 rotates counterclockwise as indicated by the arrow. To do. Since the rotation of each of these rolls 22 and 21 is in the direction of winding the IDF 23 onto the respective rolls 22 and 21, the rolls 22,
21 The part that hangs between (this part is the thermal head 25
Hangs between the rolls 22 and 21 due to contact with. )
Is wound on each roll 22, 21. Therefore, when the cartridge 40 is pulled out from the housing 12, the IDF 23 has no hanging portion, and the subsequent processing becomes convenient. Next, the cartridge 40 thus extracted is again attached to the housing 12
The cartridge 40 is inserted from the lower end of the housing 12 to mount it on the rack.
And the IDF supply roll 22 rotates counterclockwise, and the gear 45 meshes with the rack 47 to rotate the IDF winding roll 21 clockwise. Since these rotation directions are the directions in which the IDF23 is pulled out from the rolls 22 and 21, the ID23 is a roll.
A sloping portion is formed between 22 and 21, so that contact with the thermal head 25 can be performed without any trouble.

Although the IDF supply roll 22 and the IDF take-up roll 21 are both provided with gears in the above-described embodiment, they may be formed on only one of the rolls, and in this case, the rack may be either one. , The structure can be simplified.

10 and 11 show another example of the cartridge 40,
Cartridge 40 is IDF supply roll 22 and IDF take-up roll
21 is stretched over the frame 41. That is, the drive rollers 13 and 14 are attached in advance inside the housing 12 of the recording unit 2, and the cartridge 40 is composed of only IDF winding-related members. The cartridge 40 includes support plates 50, 51 provided in the housing 12.
It is inserted between and is positioned by these plates 50 and 51. Of these, the support plate 50 is the drive roller 13,
14 and the torque transmission unit 20 are pivotally supported.
An output shaft (not shown) of 20 penetrates the support plate 50 and is inserted into one end portion (the left end portion in the illustrated example) of the IDF winding roll 21 in the cartridge 40 to rotate the IDF winding roll 21. I am supposed to do it. On the other hand, the plate 51 is provided with positioning pins 52, and the frame 41 of the cartridge 40 is
A slit (not shown) through which the positioning pin 54 penetrates is formed in the. The cartridge 40 is attached to a fixed position in the housing 12 by engaging the positioning pin 52 and the output shaft of the torque transmission unit 20.

In addition to such a configuration, cartridge fixing means 53 is provided on the inner surface of the longitudinal end portion (right end portion in the illustrated example) of the housing 12. The cartridge fixing means 53 urges the frame 41 of the cartridge 40 toward the support plate 50. By this urging, the IDF take-up roll 21 inside the cartridge 40 is pressed toward the torque transmitting portion 20 and at the same time, the frame 41 Support plate by pressing in the direction of support plate 51
Removal of 51 from the positioning pin 52 is prevented. As a result, the cartridge 40 is firmly fixed at a fixed position, so that the cartridge 40 does not come off from the support plates 50 and 51 due to the rotational force of the torque transmission unit 20 accompanying the movement of the recording unit 2, and the IDF 23 is wound. It can be taken smoothly and surely. Further, the cartridge 40 does not come off due to shock or vibration during transportation. In the illustrated example, as the cartridge fixing means 53, a leaf spring bent in a “C” shape is used, and the bent piece presses the outer surface of the frame 41 of the cartridge 40. However, the invention is not limited to this. Other members such as

12 and 13 show another example of the cartridge 40. The cartridge 40 is configured by an IDF supply roll 22 and an IDF winding roll 21 pivotally supported by a cassette frame 48. This cartridge 40 is entirely a unit frame 49
It is designed to be removably incorporated into. The unit frame 49 is detachably fitted to the lower end portion of the housing of the recording unit 2 by an appropriate engaging means (not shown) such as a hook, and serves as a component of the recording unit 2. For this reason, the unit frame 49 has two drive rollers 13 and 14 around which a belt 18 is stretched at the lower end, and is connected to one drive roller 13 via a belt (not shown) to rotate and transmit. It has a piece 54. Transmission piece 54 is a cartridge
The take-up roll 21 is inserted into one end surface of the take-up roll 21 and engages with the take-up roll 21, and the rotation of the drive rollers 13 and 14 is transmitted to the take-up roll 21, whereby the IDF 23 is taken up. . In addition, the cartridge 40 is installed in the unit frame 49.
An arc-shaped guide plate 56 that supports the cartridge from below is provided, and the cartridge 40 is held stably. One side end of the unit frame 49 is open, and the cartridge 40 is inserted from this side end to be attached / detached. The cassette frame 48 of the cartridge 40 is entirely molded by plastic integral molding to reduce the weight.One end of the cassette frame 48 is extended downward, and a positioning hole 56 is formed in the extended portion. Has been formed. Meanwhile, the unit frame 49
A positioning pin 55 to be inserted into the positioning hole 56 is provided on the outer surface of the cartridge 40, and the cartridge 40 is fixed at a fixed position of the unit frame 49 by inserting the pin. The cassette frame 48 of the cartridge 40 is opened at the upper and lower parts in the center and a thermal head (not shown) is inserted into the cassette frame 48 to make contact with the IDF 23. Reference numeral 57 is a pin that is inserted into one end surface of the IDF supply roll 22 and pivotally supports the IDF supply roll 22. In such a mounted state of the cartridge 40, it is necessary to prevent accidental disengagement thereof, and the cartridge 40 and the unit frame 49 are provided with an engaging member 58 which engages with each other. In this embodiment, an engaging plate 58b protruding from the upper portion of the unit frame 49 into the frame 49 and an engaging protrusion 58a protruding from the upper end surface of the cassette frame 48 of the cartridge 40 are provided. Here, the engagement protrusion 58a can be engaged with one end surface of the engagement plate 58b when the cartridge 40 is mounted, and the unit frame of the cartridge 40.
It is formed to have a height that allows the lower surface of the engagement plate 58b to come into contact therewith when it is inserted into 49. Therefore, the engagement protrusion 58a does not hinder the insertion of the cartridge 40, and engages with the engagement plate after the cartridge 40 is mounted to prevent the cartridge 40 from being accidentally dropped. The engaging member 58 may be a hook that can be engaged and disengaged with each other. On the other hand, when the cartridge 40 is taken out, it is necessary to release the engagement between the engagement plate 58b and the engagement protrusion 58a, and the release mechanism 59 is provided. In this embodiment, the cassette frame 48 of the cartridge 40 is molded of plastic, and the portion is depressed by appropriate pressing,
It is a release mechanism that utilizes this property. That is,
The release mechanism 59 has a structure in which the vicinity of the engagement protrusion 58a is pressed and the engagement protrusion 58a is pressed down, and a dedicated release member is not required. The guide of the pressing position and the slip prevention at the time of pressing are performed, and the sliding force in the extracting direction is applied to the cartridge 40.
The release mechanism is formed by forming a plurality of ridges 59 in the vicinity of the engaging projection 58a in order to act on. in this case,
Not only the protrusions 59, but also knurls or arcuate recesses may be used.

The contact detection means 30 includes a detection roller 31 that rolls on the recording paper B as shown in FIG. 5, a contact detection unit 32 that detects contact and non-contact of the detection roller 31 with the recording paper B, and contact detection. Part 32
And a stopper means 33 for stopping the rotation of the IDF supply roll 22 in response to the signal. The detection roller 31 is always in the downward direction (recording paper B) by a biasing means (not shown) such as a spring.
Direction), the housing 12 of the recording unit 2 is moved to the recording paper B
When it is placed on the upper side, it is pushed up by the recording paper B, so that it moves upward against the biasing force. On the other hand, housing 12
When is lifted and separated from the recording paper B, it is moved downward by the urging means. The contact detection unit 32 optically or mechanically detects the movement of the detection roller 31. For optical detection, for example, a slit (not shown) may be formed in the detection roller 31, and an optical sensor having a light emitting element and a light receiving element (both not shown) on both sides of the slit may be used. An image sensor (not shown) that easily forms a mark on the optical axis and optically detects the moving amount of the mark may be used. On the other hand, mechanical detection includes, for example, a rod or an arm that moves up and down integrally with the detection roller 31 (neither is shown).
It can be configured by connecting these and the stopper means 33 by using the above. In addition, in the case of the 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 according to the output signal of this sensor is appropriately incorporated. The stopper means 33 is based on the command from the contact detection unit 32
It acts to lock and unlock the rotation of the supply roll 22. In the illustrated example, the stopper means 33 includes a lock claw 34 having a pointed bent end, and a plurality of lock grooves 35 formed at one end of the IDF supply roll 22. The lock claw 34 operates so as to approach and separate from the lock groove 35, and when the lock claw 34 meshes with the lock groove 35.
When the rotation of the IDF supply roll 22 is stopped and the engagement is released due to the separation of the lock claw 34, the IDF supply roll 2
2 becomes rotatable. In this case, the engagement of the lock claw 34 with the lock groove 35 is controlled so as to be performed in a non-contact state in which the detection roller 31 is separated from the recording paper B, that is, in a state in which the entire recording unit 2 is lifted above the recording paper B. That is, when the recording of the image is completed and the recording section 2 is lifted from the recording sheet B, the lock claw 34 and the lock groove 35 mesh with each other, and the rotation of the IDF supply roll 22 is forcibly stopped. Therefore, almost simultaneously with the lifting of the recording unit 2, the IDF 23 from the IDF supply roll 22 is
Since the supply of IDF is stopped, the IDF 23 is not excessively sent out, and it is possible to prevent the IDF 23 from slackening or wrinkling on the IDF supply roll 22 side. When the housing 12 of the recording unit 2 is placed on the recording paper B, the detection roller 31 is pushed up,
As a result, the stopper claw 34 separates from the stopper groove 35 and the mesh is released. As a result, the IDF supply roll 22 becomes rotatable, rotates as the recording unit 2 scans, and the IDF 23 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 unit 2 is separated from the recording paper B, the IDF supply roll 22 is instantaneously forcibly and rotationally locked to prevent the IDF 23 from rotating. Delivery stops. Therefore, the IDF adhered to the recording paper B behind the thermal head 25 can be peeled off as it is, and a clear image can be recorded.
Recording on the recording paper B by the IDF 23 is performed by the heat generated by the thermal head 25, and the ink or wax impregnated in the IDF 23 is melted by this heat and transferred onto the recording paper B. After the transfer, the wax is solidified after a predetermined cooling time (for example, about 0.3 sec), so that an image having a reliable density can be obtained. That is, in order to obtain a clear image, it is necessary for the IDF 23 after the ink or wax is melted to maintain the fixed state with the recording paper B for a predetermined time. When the contact detection means 30 is provided, the IDF feeding from the IDF supply side is stopped, so there is no IDF protrusion to the rear of the thermal head 25, and the recording paper of the IDF 23 after transfer located at the rear of the thermal head 25. The fixed state with B can be maintained. This ensures that the wax is solidified and the image can be made clear.

Next, an operation of recording on the recording paper B with the above configuration will be described.

First, as shown in FIG. 3A, the reading unit 3 is bent toward the front by about 90 degrees, and the copying apparatus 1 is set to the write mode. In this state, the lower end surface of the recording unit 2 is placed on the recording paper B and read / read by hand.
While pressing the light button 5, the recording unit 2 is lightly pressed against the recording paper B, and the entire recording paper B is moved from the upper end to the lower end, that is,
Move in the sub operation direction. In this state, the contact detection means 30
The detection roller 31 moves upward and the stopper means 33 is unlocked, so that the IDF supply roll 22 is in a rotatable state. Further, at least one of the drive rollers 13 and 14 comes into contact with the recording paper B, and the drive roller 13 rotates directly or via the drive roller 14 and the belt 15 due to the movement, and the encoder 17 and the rotary shaft 19 via the belts 16 and 18. Rotates. When the encoder 17 outputs the position signal according to the moving distance, the control unit 27 reads the image signal from the memory 28 and drives the thermal head 25. At the same time, the rotating shaft 19 rotates the IDF winding roll 21 via the torque transmission unit 20 that corrects the peripheral speed difference, and this rotation pulls out and winds the IDF 23 against the back tension of the IDF supply roll 22. As a result, the IDF 23 passes through the thermal head 25. At this time, when the heating resistor of the thermal head 25 selectively generates heat according to the image signal, the IDF 23 is heated to melt the ink or the like, and the image is recorded on the recording paper B.

FIG. 14 is a perspective view of another example of the contact detection means 30, in which a detection roller 31 rolling on the recording paper B is pivotally supported by a bracket 36. The bracket 36 is provided on the inner side surface of the housing 12 so as to be vertically movable, and is urged upward by a spring 37. As a result, the detection roller 31 is also biased upward. An encoder 17 is supported on the bracket 36, and a belt 38 is stretched between the shaft of the encoder 17 and the detection roller 31. In such a structure, the detection roller 31 is pressed against the recording paper B by the spring force of the spring 37. Therefore, when the copying apparatus 1 is scanned, the detection roller 31 rotates according to the movement amount thereof, and this rotation causes the belt 38 to rotate. The amount of movement is transmitted to the encoder 17 via the encoder and the amount of movement is counted. That is, the detection roller 31 also serves as a roller that detects the amount of movement of the copying apparatus. The bracket 36 is integrally formed with a lock claw 34, and the IDF supply roll 22 is provided with a lock groove 35 with which the lock claw 34 meshes.
The rotation and stop of the rotation of the IDF supply roll 22 are performed by the engagement and release of these.

In such a configuration, when the housing 12 of the recording unit 2 is pressed against the recording paper B, the bracket 36 moves upward together with the detection roller 31 and the engagement between the lock claw 34 and the lock groove 35 is released.
The IDF supply roll 22 rotates as the housing 12 moves, and the IDF23
Is smoothly supplied. With this supply, the IDF 23 is heated by the thermal head 25 and 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 D between the guide bar 26 and the thermal head 25, and the image transfer is performed. Next, when the housing 12 is lifted from the recording paper B, the spring
The detection roller 31 and the bracket 36 integrally move downward by the spring force of 37, and the lock claw 34 meshes with the lock groove 35. As a result, the rotation of the IDF supply roll 22 is locked, and the excess IDF 23 is not sent out. Therefore, after solidifying the ink or wax, the ID fixed to the recording paper B on the rear side of the thermal head 25.
F23 can be peeled off from the recording paper B.

15 and 16 show the ID passing through the thermal head 25.
This is an embodiment in which a guide member 60 of F23 is provided. The guide member 60 is provided so as to surround the thermal head 25, and is fixed in the housing 12 by screwing, welding or the like. This guide member
60 is the first guide surface 61 located on the supply side of the IDF 23 and the IDF
A second guide surface 62 located on the winding side of 23, and the thermal head 25 is inserted into the closed cross-section passage formed by these guide surfaces 61, 62. FIG. 17 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. Further, mounting grooves 64 of the thermal head 25 sandwiched by the control board 27 and the thermal head fixing plate 29 on both sides and integrated with these are formed on both sides. The mounting groove 64 is formed so as to be fitted into both ends of the integrated thermal head 25, the control board 27, and the thermal head fixing plate 29, and the thermal head 25 is firmly fixed in the guide member 60 by the insertion. Fixed. 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 does not move in the scanning direction, so that there is no rattling of the thermal head 25. , Stable image quality transfer becomes possible. Since the mounting groove 64 is open in the insertion direction (vertical direction) of the thermal head 25 and freely moves up and down with respect to the pressure applied to the thermal head 25 during transfer, the pressure can be smoothly applied. it can.

First guide surface 61 and second guide surface of guide member 60
When the image is recorded on the recording paper B 62, the IDF 23 is in sliding contact. These guide surfaces 61, 62 are formed in a shape and position where the IDF 23 is smoothly guided. The first guide surface 61 is IDF
The IDF 23 supplied from the supply roll 22 is transferred to the thermal head 25.
To guide you. In supplying the IDF 23 from the first guide surface 61 to the thermal head 25, it is preferable that the IDF 23 be appropriately tensioned and move smoothly. Therefore, as shown in FIG. 18, the first guide surface 61 is provided with an amount α with the lower end surface of the thermal head 25 so that the lower end edge is located higher than the lower end surface of the thermal head 25. , The angle γ formed by the normal line at the contact point of the IDF 23 and the horizontal axis is set to a predetermined value. These α
And γ are appropriate depending on the type of base material of IDF23, thickness, etc.
For example, when the IDF substrate is, for example, a 0.6 μm thick polyester film, α can be set to about 1.5 mm and γ can be set to about 41 °. Further, it is preferable that a portion (lower edge) where the first guide surface 61 comes into contact with the IDF 23 has a shape in which a central portion is slightly raised downward as compared with both ends in the width direction. FIG. 19 shows the shape of the lower end edge 61a of the first guide surface 61, and the straight line connecting both ends of the lower end edge 61a is the x-axis,
When the y-axis is formed from the central portion of the first guide surface 61 with respect to the x-axis, the lower end edge 61a of the first guide surface 61 has the lowest local minimum value at the central portion intersecting the y-axis. Both sides of the curve are quadratic curves that rise with the same curvature. With such a shape, the lower end edge 61 of the first guide surface 61
The IDF 23 that comes into contact with a is given tension toward both sides in the width direction, wrinkles and skew are eliminated, and smooth supply is performed. The minimum value is IDF23.
Is the above-mentioned substrate and thickness, the range of 0.15 mm ± 50 μm is preferable. Next, the second guide surface 62 provided on the winding side of the IDF 23 is provided to smoothly peel off the IDF 23 fixed to the recording paper B by the heat generation of the thermal head 25. In this case, it is preferable from the standpoint of transfer density that the IDF23 is kept in contact with the recording paper B while the wax in the IDF23 is solidifying (the cooling time is about 0.3 sec described above), and then the peeling is performed. It is preferable to carry out simultaneously in the width direction of the recording paper B. The second guide surface 62 is formed in consideration of such a point, and as shown in FIG. 18, the distance δ between the lower end surface of the thermal head 25 and the lower end surface of the second guide surface 62 and the thermal head 25 The height β of the lower end surface of the second guide surface 62 from the end surface is appropriately selected. These numbers are IDs
It is changed depending on the material of F23, etc.
In the above case, δ is preferably about 3.5 mm and β is preferably 0.2 mm or less. Further, the lower end surface of the second guide surface 62 that contacts the IDF 23 is formed by a horizontal straight line. As a result, the ID after transfer
The F23 is smoothly peeled off from the recording paper B by the second guide surface 62, and a clear and stable image can be formed. The first guide surface 61 and the second guide surface 62 as described above are the guide bars 24 shown in FIG. 4 and FIG.
It can also be obtained by forming and 26 and 26 in the above-described shapes and dimensions and providing them at predetermined positions.

FIG. 20 is a block diagram showing an example of transfer control of the thermal head 25. This control is to remove the wrinkles of the IDF23 generated at the beginning of the transfer by idly feeding the IDF23 without performing the transfer at the start of the transfer. The transfer control means 65 measures a pulse signal from the encoder 17 which receives the rotation of the drive roller 13 and converts the moving amount of the recording portion by the manual driving scanning, and the moving amount from the counter 66 and the transfer start position. A comparator 67 that compares the set value from the setting unit 68, a transfer start position setting unit 68 that sets the transfer start position, and a drive unit 69 that drives the thermal head 25 by a signal from the comparator 67 are provided. There is.
Such a transfer control means 65 is incorporated in the control board 28 of the thermal head shown in FIGS. 4 and 5, for example. The transfer start position setting unit 68 is the thermal head 25.
When the thermal head 25 is moved on the recording paper B from the position where the sheet is pressed against the recording paper B, a region (non-transfer region) where transfer is not performed is set. The counter 66 counts the time when the thermal head 25 is pressed against the recording paper B as "0", and measures the moving amount of the thermal head 25 from the pulse signal input from the encoder 17 in units of mm or 0.1 mm. The comparator 67 compares the movement amount with the set value (8
Pulse / mm). As a result of the comparison, when the movement amount <the set value, no signal is sent to the drive unit 69, but when the movement amount ≧ the set value, a signal is sent to the drive unit 69, whereby the drive unit 69 causes the thermal head 25 to move. To drive. Transfer to recording paper B is performed by this drive, but until this drive is started, ID
A predetermined amount of F23 is idly fed and wound around the IDF winding roll 21. Due to this idling, the IDF 23 has an IDF supply roll 22 that is back tensioned and an ID that winds up the IDF.
Wrinkles and the like are removed during idling because the tension is applied by being pulled between the F winding roll 21 and the F winding roll 21. Therefore, as shown in FIG. 21, when the transfer is started, the IDF 23 is in an appropriate tension state, so that it is possible to perform good transfer with no transfer dropout and smoothly perform winding. it can.

Such an operation can be performed without setting the transfer control means 65 by setting the winding amount of the IDF winding roll 21. That is, it can be performed by urging the IDF winding roll 21 so that the winding amount of the IDF winding roll 21 is always larger than the moving amount of the IDF 23 passing through the thermal head 25.

FIG. 22 shows a cross-sectional view of the internal structure of the reading unit 3, in which the reading unit 3 is readable (read mode) when it is located directly below the recording unit 2, and while the read / write button 5 is being pressed, The information on the document A is read by scanning the document A. The reading unit 3 includes an LED array 71 as a light source that irradiates the document surface with light, and a self-focus lens that forms an image of the document surface illuminated by the LED array 71 at a predetermined position.
72, a contact-type image sensor 73 for photoelectrically converting an optical image from the SELFOC lens 72, a roller 74 that rolls the document surface and is connected with an encoder, and the image information read by the image sensor 73 is stored. Memory 75 (the same memory as the memory 28 in the recording unit 2), a control unit 76 that controls the address of image information and the transfer timing of data to the memory 75, and a position that outputs an electric signal according to the rotation of the roller 74. It is composed of a detector (not shown) and a housing 78 containing the above-mentioned members.

As shown in FIG. 23, the housing 78 has a lower surface which is in contact with the original A and is curved downward, and a substantially central portion thereof is a flat contact surface 78 a which is in close contact with the original A. And L on the contact surface 77
A transparent reading window 79 is provided which transmits the light from the ED array 71 and receives the reflected light from the document A. The entire casing 78 is integrally formed of transparent resin. As the transparent resin, acrylic resin having a transmittance of 90% or more of light in the visible region is used. Then, on the inner surface of the housing 78, a light blocking film 77 is formed on the entire surface of the contact surface 78a except the substantially central portion thereof. The portion where the light blocking film 77 is not formed serves as the reading window 79. The reading window 79 is formed by forming the light blocking film 77 on the housing 78 after the housing 78 is integrally molded. There is. The light-blocking film 77 is formed so as to have a light transmittance close to 0%, and blocks light from portions other than the reading window 79, so that light from the portion other than the reading window 79 enters the housing 78. It is possible to prevent erroneous reading of image information without incidence. The light blocking film 77 is made of a material having a light blocking ability, and a shield member having the same shape as the housing 78 is formed in advance so that the reading window 79 is opened. It is also possible to form it by fitting it on the outer surface or inner surface of the housing 78, or even on both surfaces thereof with black paint or the like that absorbs light in the visible region. Alternatively, a metal film of aluminum, silver, or the like may be vapor-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 reading window 79 is in contact with the original surface by covering the portion excluding the reading window 79 with the light blocking film 77. There is no catch on the original during reading and scanning, and there is no inconvenience such as the original being damaged or being unable to read. Further, since the contact surface 78a with the original A is a flat surface and dust is unlikely to adhere and can be easily removed even if it adheres, it is possible to read the image information with high accuracy without reading the dust as image information. it can. Furthermore, since the housing 78 is formed by integral molding of transparent plastic, it is possible to mold the housing 78 in large quantities with high precision.

FIG. 24 shows a case where the reading unit 3 is configured separately from the recording unit 2, and the respective members inside the housing 78 are the same as those in FIG. Is made of a transparent resin, and a portion except a reading window 79 (not shown) is covered with a light blocking film. Also, in this example, the memory 75 is
Can be attached to and detached from the side of the
The memory 75 can be removed and attached to an appropriate reproducing device (not shown) to display image information, or it can be attached to a recording device (not shown) to transfer it to recording paper. Further, the reading unit 3 can be connected to a display device (not shown) such as a CRT for displaying, or can be connected to a facsimile device for transfer to the other party.

FIG. 25 shows the internal mechanism of the reading unit 3. In the figure, as shown in FIG. 26, the reading unit 3 is placed on the document A at a distance X (for example, X
= 1 mm) When scanning, the image information G of the original A is newly stored while erasing the previous image information stored in the memory. 26, the broken line F indicates the image input position, and the solid line E indicates the front edge of the reading unit in the scanning direction. The internal structure of the reading unit 3 includes a reader / writer detection unit 81 for detecting whether the copying apparatus 1 is in a read mode (shown in FIG. 2) or a write mode (shown in FIG. 3), and a read / write button. The switch 83 that is closed by pressing 5 (FIG. 1), the output signal of the reader / writer detector 81, and the switch 83
AND gate 82 which takes the logical product with the signal of, the start signal generation circuit 84 which generates the start signal by the signal from the AND gate 82, the encoder 85 connected to the roller 74 (Fig. 22), and the start signal generation An AND gate 86 that takes the logical product of the start signal from the circuit 84 and the pulse signal from the encoder 85, and the movement distance X of the reading unit 3 is measured based on the pulse from the AND gate 86 and a drive pulse generation signal is output. A distance count circuit 87, an image sensor drive pulse generation circuit 88 that generates a drive pulse for the image sensor 89 based on a signal from the distance count circuit 87, and an image sensor 89 that photoelectrically reads the reflected light from the document and reads it. , A binarization circuit 92 for binarizing the video signal from the image sensor 89 and a drive pulse from the image sensor drive pulse generation circuit 88. A serial / parallel register 90 for converting the signal output from the binarization circuit 92 into parallel data in an expected manner, and a frequency divider circuit for dividing the drive pulse from the image sensor drive pulse generation circuit 88 into, for example, 1/8. 91 (dividing ratio depends on how many bits are read in 1 mm), address generating counter 93 that counts the output pulse of dividing circuit 91 to determine the address for memory 94, and output from serial / parallel register 90 Memory 94 for storing the stored data at the address designated by the address generation counter 93.

In the above configuration, when the reading unit 3 of the copying machine (read mode) is placed on the original and the read / write button 5 is pressed to turn on the switch 83, the reader / writer detection unit
AND gate 84 is the logical product of the signal of 81 and the signal of switch 83.
The start signal generating circuit 84 generates a start signal according to the output signal of the AND gate 84. On the other hand, the encoder 85 generates a pulse signal according to the rotation of the roller 74, and the AND gate 86 takes the logical product of the pulse signal of this encoder 85 and the start signal of the start signal generation circuit 84, and the AND gate 86 The distance counting circuit 87 counts the moving distance based on the pulse of. The distance counting circuit 87 does not output a pulse signal to the image sensor driving pulse generating circuit 88 until the moving distance reaches a predetermined value X (for example, 1 mm), and generates the image sensor driving pulse only when the distance X reaches the predetermined value. Output to circuit 88. That is, the image sensor 89 does not start reading until the movement distance reaches a predetermined value, and during the movement to the predetermined value,
The image information read last time is stored in the memory 94. Therefore, even in the case of an erroneous operation, the previous image information is stored in the memory 94 by stopping the operation during movement of a distance equal to or less than the predetermined value, and thus the previous image information can be reproduced. In this case, stopping the operation stops the movement of the device or
This can be done by releasing the pressing of the tight button 5. Next, after the moving distance reaches the predetermined value X, the distance counting circuit 87 sequentially outputs the image sensor drive pulse signal. The video signal read by the image sensor 89 is binarized by the binarization circuit 92, converted into parallel data by the serial / parallel register 90, and output to the memory 94. In this case, the 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 image sensor 89, and the frequency dividing circuit 91 counts this and every eight drive pulses are counted. The address generation counter 93 is incremented.
The counter 93 supplies address data to the memory 94 each time the counter 93 counts up, and 8-bit image data synchronized with the frequency dividing pulse of the frequency dividing circuit 91 is stored at the address designated thereby.

With such a configuration, the reading of the image sensor 89 is prohibited when the movement amount is equal to or less than the predetermined value, and the previous image data is stored in the memory 94. Therefore, it is possible to prevent the image data from being erased by an erroneous operation. Although the reading unit has been described in the above configuration, the distance kinting circuit 87 may be incorporated in the recording unit 2 and the thermal head 25 may be start-driven by a signal from the circuit 87. As a result, it is possible to prevent data erasure due to an erroneous operation during recording.

FIG. 27 is a block diagram of the signal processing means provided between the image sensor 89 and the binarization circuit 92. Inversion for amplifying and outputting the video signal from the image sensor 89 based on a predetermined power supply voltage. Amplifier circuit 105 and inverting amplifier circuit 1
It has an integrating circuit (low-pass filter circuit) 101 that cuts high-frequency components of the video signal output from 05.
The binarizing circuit 92 compares the video signal from the inverting amplifier circuit 105 with the output signal from the integrating circuit 101 and outputs the result. FIG. 28 is a circuit diagram of a portion including the integrating circuit 101 and the binarizing circuit 92. The integrating circuit 101 is an inverting amplifier circuit 105.

And a comparator 102 connected to the voltage dividing circuit 95. The voltage dividing circuit 95 has resistors r ₁ , r
₂ and r ₃ , the video signal integrated by the integrating circuit 101 is divided, and this is output to the comparator 102 as a binarized reference signal (threshold level) for binarization. The comparator 102 binarizes the video signal from the inverting amplifier circuit 105 based on the binarized reference signal,
Output as a pulse signal composed of the igh signal and the Low signal. Here, among the resistors r _1, r _2, r ₃ of the voltage dividing circuit 95, r ₁ connected in series to the comparator 102 is a thermistor whose resistance value changes in accordance with the temperature is used to detect the environmental temperature , Even if the environmental temperature fluctuates, a constant partial pressure is always applied.
That is, the thermistor r ₁ serves as a voltage dividing control means for compensating the temperature so that the voltage dividing in the voltage dividing circuit 95 does not change according to the environmental temperature, and thereby outputs the threshold level at a value within a constant range at all times. can do. Since the comparator 102 performs binarization based on the constant threshold level in this way, it is possible to reproduce an image having the same density as the image information of the document. First
FIG. 29 is a timing chart showing the operation based on the above configuration. The video signal H of the image sensor 89, which has been inverted and amplified by the inverting amplifier circuit 105, and the threshold level V _TH, which has been processed by the integrating circuit 101 and then divided by the voltage dividing circuit 95, are compared by the comparator 102 to obtain 2
The binarized signal J is output. In this binarization, a Low signal (0) is output when the threshold level V _TH is lower than the video signal H, and a High signal (1) is output when the threshold level V _TH is high. FIG. 5V shows the threshold level when a fixed resistor is used as the resistance r ₁ of the voltage dividing circuit 95. When the environmental temperature rises (for example, 20 ° C.) in the same environment, the resistance value of the fixed resistor of the voltage dividing circuit 95 increases, so that the threshold level V increases, but when the thermistor r ₁ is used, the temperature rises. Since the resistance value changes as it rises, the threshold V _TH maintains a constant value. Therefore, the binarized signal J obtained by the comparator 102
Is output with the same density as the image information.

FIG. 30 shows the internal mechanism of the reading unit using the image sensor 100 composed of a CCD with high sensitivity such as 90 V / l _x · sec.
Figure 1 shows the circuit diagram. Here, the sensitivity of 90 V / l _x · sec means that an output of 90 V can be obtained by irradiating a light amount of 1 _x for 1 second. Such a high-sensitivity image sensor
Since 89 has a sharp response to light, it responds to a slight change in the amount of light reflected from the document and the amount of exposure increases. When this exposure amount increases, a large time delay occurs in the integration processing, and a deviation occurs between the binarized reference signal generated after the integration processing and the video signal not subjected to the integration processing, which hinders the binarization processing. 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, the integrating circuit 1
01. In addition to the binarization circuit 92, when the output of the image sensor 89 exceeds a predetermined value, a signal processing control circuit 103 that electrically cuts the output, a signal from this circuit 103, and a binarization circuit 92 An AND gate 104 is provided to take the logical product of the binary signal from the and output. The inverting amplifier circuit 105 supplies the video signal from the image sensor 89 as shown in FIG.
It has an amplifier 106 that inverts and amplifies based on the voltage of V _DD , and outputs the inverted and amplified video signal to the integration circuit 101, the binarization circuit 92 and the signal processing control circuit 103. Integrating circuit 1
01 is a circuit for cutting high frequency components of the video signal amplified by the inverting amplifier circuit 105, and has a comparator 107 for that purpose. The binarizing circuit 92 has a comparator 102 and the voltage dividing circuit 95, and binarizes the output signal from the component circuit 101 and the video signal from the inverting amplifier circuit 105 by comparing them. In the binarization circuit 92, the inverting amplifier circuit 105
The low signal (0) is output when the output signal of the integrating circuit 101 is low with respect to the video signal from, and the High signal (1) is output when the output signal is high. Binarized by this binarization circuit 92
The binarized signal is output to the AND gate 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. In addition, resistors r ₄ and r that divide the power supply voltage V _DD to give a constant reference value voltage
₅ , the reference value voltage is input to the judging device 109. The decision unit 109 compares these signals,
If the inverted and amplified video signal is higher than the reference voltage,
Output Low signal. The AND gate 104 takes the logical product of this Low signal and the binarized signal from the binarization circuit 102 and outputs it.

The operation of the above configuration will be described based on the timing chart of FIG. An integration circuit for the video signal H of the image sensor 89 that is inverted and amplified by the inverting amplification circuit 105.
The integrated value signal I from 101 is generated with a time delay. Here, the Ha portion in the video signal H has a saturation output that is 3 to 4 times the saturated output of the image sensor (for example, saturated output voltage / V), which is 3 to 4 times the light amount normally received from the document. Is the part where the light enters. That is, it is the portion that receives the reflected light from the gap that is not in close contact with the document. The binarization circuit 92 compares the video signal H with the integrated signal I, outputs a Low signal (0) when H> I, and H <I
In the case of, the High signal (1) is output and converted into the binarized pulse signal J. Further, the video signal H from the inverting amplifier circuit 105 is input to the determiner 109 of the signal processing control circuit 103. In the judging device 109, the reference value voltage K is input from the resistors r ₄ and r ₅ , and when the video signal Ha is equal to or higher than the reference value voltage K (Ha portion), the low signal L is output to the AND gate 104. The AND gate 104 takes the logical product of this low signal L and the binarized signal J from the binarization circuit 102. The supersaturated portion Ha output from the image sensor 89 is cut by this logical product. That is, the signal due to the reflected light based on the light that has entered through the gap between the original and the original is deleted, and an accurate signal that matches the image information of the original can be output to the memory. As a result, reading of an erroneous signal due to light entering through the gap does not occur, and a reproduced image of good quality can be obtained.

When the linear encoder 213 moves the scale 211 in the length direction and is stopped at a predetermined position, the stop position is measured by the number of passages of the scale 212 and output to the reading control means 201. The reading control unit 201 determines that the area from the slide start end to the stop position is the reading area in the main scanning direction. As a result, the reading control means 201 drives only the reading means 200 within the designated area, and controls so that the reading means 200 other than the designated area are not driven. 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. In such a configuration, it is possible to drive only the reading unit 200 having a length required when the reading width of the document is shorter than the reading unit 200, so that it is possible to reduce the power and the light source,
