Therefore, as in this embodiment, the ink sheet 1 is placed in the first housing 4a.
By setting it to , cutting and repair work becomes easier. Further, in this embodiment, the U for fitting the bearing 8 is
Since the grooves 4c and 4d are provided only in the first housing 4a and the ink sheet 1 cannot be set on the second housing 4b side, the ink sheet 1 cannot be set on the second housing 4b during maintenance, for example. This prevents situations such as being attached backwards.

The supply reel 2 and take-up reel 3 with the ink sheet 1 wound thereon as described above are set in the first housing 4a, and as shown in FIGS. 5 and 6, the second housing 4b is rotated so that both The engagement recesses 4p and the engagement protrusions 4q of the cylinders 4a and 4b are engaged.

Incidentally, as shown in FIG. 6, the ink cartridge A having the above structure is provided with a lid 4g over the opening 4r for inserting the recording head.
It is possible to prevent dust and the like from entering the cartridge A from the inside of the cartridge A, and it is also possible to prevent the ink sheet 1 from being damaged, and since the inside is hidden, it can give a sense of luxury.

Next, the configuration of the recording apparatus B for carrying out thermal transfer recording by loading the ink cartridge A will be described.

The recording apparatus B according to this embodiment is configured as a recording system of a facsimile machine having an image reading system C, as shown in FIG. This recording device B is constructed so that it can be opened and closed by rotating a main body 10 and a recording cover 1) around a hinge shaft 12, and is configured such that the ink cartridge A is loaded into the recording cover 1). ing.

On the side of the apparatus main body 10, there are a roll holder 13 for loading a sheet roll 7a in which a long recording sheet 7 is wound into a roll, a platen roller 6b serving as a conveying means for conveying the recording sheet 7, and a recording device. A cutter 14 for cutting the subsequent recording sheet 7 and a discharge roller 15 for discharging the sheet 7 are provided.

On the other hand, on the recording cover 1) side, a line-type recording head 6a is attached as shown in FIGS. 2 and 7(A). when the recording cover 1) is closed.
a is configured to press the platen roller 6b by a pressing spring 6C. In addition, the recording cover 1
), the fork members 6d attached to both ends of the recording rack 6a sandwich and position the shaft 6b of the platen roller 6b.

Furthermore, the configuration of the image reading system C is such that a plurality of originals 17 are stacked and stacked on an original placing table 16 formed on the upper surface of the recording cover 1), and the originals 17 are preliminary transported by preliminary transport rollers 18a and pressing rollers 18b. At the same time, the original document 17 is separated and fed one by one by a separation roller 19a and a pressure contact piece 19b that is in pressure contact with the separation roller 19a, and the document 17 is transported by a pair of transport rollers 20a and 20b and discharged onto a discharge tray 21. While the original 17 is being conveyed, the original surface is irradiated with light from the light I [22, and the reflected light is directed to a photoelectric conversion element 25 such as a CCD via a mirror 23 and a lens 24, and both signals are copied. In the mode, the data is transmitted to its own recording system, and in the transmission mode, the data is transmitted to the recording system of another machine.

In FIG. 2, 26 is an electrical board, and 27 is a power source for driving members such as a motor, which will be described later.

A control system for driving and controlling the device is constructed as shown in the block diagram of FIG.

To explain its configuration in detail, in FIG.
It is equipped with 6. Line memory 50a in the control unit 50
is used to store image data for each line of image data; when transmitting or copying the original 17, one line of image data from the reading system C is stored; when receiving image data, it stores the combined received image data. Image data 1

0b is an encoding/decoding unit that encodes the image information to be transmitted by MH encoding or the like, and decodes the received encoded image data to convert it into image data. 50 again
c is a buffer memory that stores encoded image data to be transmitted or received. Each part of the control unit 50 is controlled by a CPU 50d such as a microprocessor. Note that the control unit 50 includes the CPU 50d (7
) In addition, there is a ROM50e that stores the cptJ50d control program and various data, and a RAM2Of that temporarily stores various data as a work area for the CPU50d.
etc.

The recording system 51 includes the recording head 6a described above and motors (reel drive motor 32 and platen motor 3, which will be described later).
7) and is driven by a signal from the CPU 50d. Reference numeral 52 denotes an operation section including various function instruction keys such as starting transmission, telephone number input keys, and the like. 5 more
Reference numeral 3 denotes a display section for displaying various functions provided in the operation section 52, the status of the device, and the like.

Further, 54 is a modem (modulator/demodulator), and 55 is a network control unit (NCυ).

Next, the configuration of the loading section 5 for loading the ink cartridge A will be explained.

On both sides of the record cover 1), as shown in Figure 7 (^),
A positioning member 28 formed laterally symmetrically is attached. This positioning member 28 is the ink cartridge A.
a key-shaped groove 28a for locking the guide pin 4e;
Glue grooves 28b and 28c are provided at a predetermined interval on the same extension line to fit into and position the bearings 8 fitted to both ends of the reel 2.3. Further, a locking spring 29 for locking with the locking protrusion 4n of the ink cartridge A is provided near the open end of the recording cover 1).

Therefore, as shown in FIG. 7(A), the guide pin 4e of the ink cartridge A is fitted into the key-shaped groove 28a, and the ink cartridge A is rotated around the guide pin 4e. As shown in (B), the locking protrusion 4n
The ink cartridge A is loaded into the recording cover 1) by being locked to the locking spring 29. At this time, bearing 8
are the respective U grooves 28b.

28c.

When loading the ink cartridge A, the guide pin 4 of the ink cartridge A is
Since the U grooves 4c and 4d into which the bearings 8 and the bearings 8 are fitted are arranged in a straight line, when the ink cartridge A is rotated around the guide pin 4e, the bearings of the supply reel 2 and the take-up reel 3 8 is the U groove 28b of the positioning member 28, 2
They are positioned substantially simultaneously with respect to 8c. Therefore, the bearing 8 is reliably positioned and fitted into the U grooves 28b and 28C of the positioning member 28.

Furthermore, a U groove 4c into which the guide pin 4e and the bearing 8 are fitted;
4d are both provided on the first housing 4a side, and are arranged in a straight line, so that the key-shaped groove 28a and the U-groove 28b are formed in the member 28 for positioning these.
, 28c are also arranged in a straight line, so that the bearing 8 is accurately positioned with respect to the guide pin 4e. That is, high positional accuracy can be obtained when positioning the bearing 8 simply by arranging the key-shaped groove 28a and the U-grooves 28b, 28c in a straight line on the positioning member 28, which is one member.

Incidentally, the positioning member 28 of this embodiment has, in the thickness direction,
As shown in FIG. 9(^), the inner surface 28d is tapered so that the space between the two positioning members 28 is wide at the bottom and gradually narrows toward the top. As a result, when the ink cartridge A is rotated around the guide pin 4e, it is guided along the taper, making it easy to load. This prevents wobbling in the direction of arrow Y).

Furthermore, when loading the ink cartridge A as described above, the fork member 6d attached to the recording head 6a twists the M4g of the ink cartridge A, as shown in FIGS. As a result, the recording head 6a is inserted into the ink cartridge A from the opening 4r of the ink cartridge A.

Note that when inserting the recording head 6a into the opening 4f,
The guide pin 4e is provided at the end of the cartridge A, and since there is a certain distance from the guide pin 4e, which is the center of rotation, to the opening 4f, the size of the opening 4f is determined to be large enough to insert the recording head 6a. It is possible to make it approximately equal to the minimum necessary size.

In addition, the biasing force (
The force that tried to return 14g to the closed state) is shown in Figure 10 (B
), insert the recording head 6a and
The force is such that it does not affect the pressing force when a is pressed against the platen roller 6b. Therefore,
In this embodiment, the recording hand drawer a by the pressing spring 6c is
The pressing force between the lid 4g and the platen roller 6b is set to about 15hf/cs, while the urging force of the lid 4g by the torsion coil spring 41 is set to about 608f/cs.

When the ink cartridge A is loaded as described above, the recording head 6a! Since the cartridge 4g is automatically opened and inserted into the cartridge A, the cartridge A can be easily loaded. Further, since the lid 4g is opened in a double-door manner by the pressure of the recording head 6a, the radius of rotation of each 14g is small, and the length of the ink cartridge A in the height direction can be shortened.

As described above, attach the ink cartridge A to the recording cover 1).
(the state shown in FIG. 7(B)), the cover 1) is closed, and the hook 30a of the apparatus main body 10 and the hook 30b of the recording cover 1) are engaged.

At this time, reel gears 2c and 3c integrally formed with the supply reel 2 and take-up reel 3 are configured to mesh with a driving force transmission gear 31 attached to the apparatus main body 10 side.

To explain this specifically, as shown in FIG. 7(B), a reel drive motor 32 for driving and rotating each reel 2.3 is attached to the main body 10 side of the recording apparatus B. The driving force from 32 is transmitted to gear trains 33a to 33.
The driving force is transmitted to the driving force transmission gear 31 via e. The gear 33e is attached to an arm 34 that is rotatable around the gear shaft of the gear 33d, and is configured as a so-called pendulum gear that can swing around the gear 33d while remaining in mesh with the gear 33d. ing. The driving force transmission gear 31 can swing integrally with the pendulum gear 33e, and is configured such that the rotational force from the pendulum gear 33e is transmitted via the slip clutch 35.

Note that 36 in FIG. 7(B) is a tension spring for pulling the arm 34 upward. Further, 37 is a platen motor for rotating the platen roller 6b, and the driving force of this motor 37 is transmitted to the platen roller 6b via gear trains 38a to 38c.

In the above configuration, when the recording cover 1) is closed, the reel gear 2 is exposed from the opening 4m of the ink cartridge A.
c and 3c come to mesh with the driving force transmission gear 31, but in this embodiment, the opening 4m is the first one shown in FIG.
, As shown in (B), the hinge shaft 1 of the recording cover ll
It is provided so as to be located on the rotation locus circle of reel gear 2C13C centered on reel gear 2C13C, and driving force transmission gear 3
1 is also provided so as to be located on the trajectory circle. Therefore, when the recording cover 1) is closed, the gears 2c and 3c exposed from the opening 4m press the driving force transmission gear 31 and are securely engaged. At this time, even if the parent gear 33d connected to the motor 32 is in the locked state, the pendulum gear 33e that swings integrally with the driving force transmission gear 31 will not be connected to the parent gear 33.
In order to smoothly swing around the recording cover 1)
can be closed smoothly.

Further, on the apparatus main body IO side, as shown in FIG. 7(B), leaf springs 39 serving as pressing members are located at positions facing the bearings 8 of the ink cartridges A attached to the recording cover 1).
is attached to the U groove 28b of the positioning member 28.

28c side. For this reason, the bearing 8 is shown in FIG.
As shown in B), the height direction (arrow 2 directions in Fig. 7 (B))
positioning is performed reliably. The plate spring 39 is inserted into the U groove 28b of the positioning member 28 as shown in FIG. 9(B).
, 28c in the reel axial direction. For example, if the plate spring 39 and the positioning member 28 do not match in the reel axial direction, the bearing 8
A twisting force is applied to the reel 2.3, and an unnecessary frictional force is applied to the rotation of the reel 2.3. However, in this embodiment, the above-mentioned disadvantage does not occur.

As described above, the bearing 8 is inserted into the U groove 28b of the positioning member 28.
, 28c, and the positioning when loading the ink cartridge A into the recording cover 1) and the positioning of the bearing 8 are configured independently.

That is, by directly positioning the bearing 8 to the recording apparatus B without using the ink cartridge A, it is possible to improve the accuracy of the parallelism between the reel 2.3 and the platen roller 6b. Further, since the ink cartridge A does not require strict positional accuracy of the bearing 8, there is no need to require rigidity or accuracy in the cartridge A, and therefore the cartridge A can be manufactured at low cost.

Furthermore, in this embodiment, when the recording cover 1) is closed,
As shown in FIG. 10(B), the pressure contact portion between the recording head 6a and the platen roller 6b is configured to be located approximately at the middle of the ink cartridge A in the height direction. When the pressure contact portion is located above the ink cartridge A, a notch 4 for escaping the shaft of the platen roller 6b shown in FIG.
Il, had to be made deeper, so the second casing 4b
On the other hand, if the pressure contact portion is located lower in the ink cartridge A, the opening 4f for inserting the recording head 6a must be made larger; however, in this embodiment, Since the press-contact portion is located approximately at the center, the strength of the second housing 4b is not weakened, and the opening portion 4f can be minimized to a necessary minimum.

Next, a case will be described in which printing is performed using the printing apparatus B loaded with the ink cartridge A.

During recording, the platen motor 37 and the reel drive motor 32 on the take-up reel side are driven, and the reel drive motor 32 on the supply reel side is locked. When the platen motor 37 is driven, the platen roller 6b
rotates in the direction of arrow a in FIG. 12, and conveys the recording sheet 7 and the ink sheet l superimposed thereon in the directions of arrows a and c, respectively. In synchronization with this, the heating element 6a1 of the recording head 6a generates heat in accordance with the image signal to heat the ink sheet 1 in an image pattern, and the ink melted by this heating is transferred to the recording sheet 7.

During the recording, the motor for driving the take-up reel 3 operates so that the circumferential rotational speed of the take-up reel 3 is slightly smaller than the circumferential rotational speed of the platen roller 6b so that the ink sheet 1 conveyed by the platen roller 6b does not slacken. The slip clutch 35 absorbs the faster speed. As a result, the ink sheet 1 is wound onto the take-up reel 3 while being given front tension. On the other hand, since the reel drive motor 32 on the supply reel 2 side is locked, the supply reel 2 is
It receives a sliding load of 5 and rotates as the ink sheet l is fed out. Back tension run is applied to the ink sheet 1 due to this sliding load.

In addition, in FIG. 12, the ink sheet l is on the winding rule
If the sheet 1 has a strong force pressing the recording head 6a upward due to the front tension when it is wound up,
The pressing force of the recording head 6a against the platen roller 6b changes, and in extreme cases there is a possibility that image waves may be caused, but in this embodiment, the ink sheet 1 is guided by the guide shaft 4. Therefore, even if the front tension of the ink sheet 1 is strong, the recording hand drawer a is not pressed upward by the ink sheet 1.

Therefore, the platen roller 6b by the recording head 6a
The pressing force is always constant, and there is no fear that the image wave will cause distortion.

Further, as shown in FIG. 12, the reel gear 2c on the supply reel 2 side receives an upward force due to the driven rotation of the driving force transmission gear 31 which is subjected to a sliding load. The U grooves 28b and 28c are installed so that the bearing 8 does not move upward because it is supported by the reel gears 2c and 3c. Therefore, the reel gears 2c, 3c do not move, and so-called tooth skipping between the reel gears 2c, 3c and the driving force transmission gear 31 is prevented.

Next, a case where the ink cartridge A is replaced or removed from the recording cover 1) will be explained.

In this case, as shown in Figure 7 (B), the recording cover 1)
When the handle 40 of the ink cartridge A is released and the handle 40 of the ink cartridge A is grasped and pulled, the engagement state between the locking protrusion 4n of the ink cartridge A and the locking spring 29 is released, and the ink cartridge A is released as shown in FIG. 7(A). rotates around the guide pin 4e and can be easily removed from the recording cover 1).

At this time, since both the handle 4o and the locking protrusion 4n are provided on the second housing 4b side, even if the handle 4o is pulled, the retaining portion between the first housing 4a and the second housing 4b, that is, the engagement No force is applied to the engagement portion between the mating recess 4p and the engagement protrusion 4q. Therefore, when the engagement protrusion 4n is removed from the engagement spring 29, the first casing 4a and the second casing 4b are It will never open.

As described above, the ink cartridge A according to this embodiment can be easily loaded into the recording apparatus B to which the recording head 6a is attached with high positioning accuracy, and can be easily loaded into the recording apparatus B to which the recording head 6a is attached. It is possible to prevent gear tooth skipping and perform high-quality recording.

[Other Examples]

In the first embodiment described above, an example was shown in which the ink sheet 1 was conveyed in the same direction as the recording sheet 7 when recording.
As shown in FIG. 13, the ink sheet 1 may be transported in the opposite direction (direction of arrow d) to the transport direction of recording sheet 7 (direction of arrow d).

In this case, the structure of the ink cartridge A is the same as that of the first embodiment except that the supply reel 2 and take-up reel 3 are reversed.

Further, in this configuration, the reel gear 3 of the take-up reel 3
c is configured to be connected to the reel drive motor via a gear train without using a slip clutch. In this configuration, during recording, the recording sheet 7 is conveyed in the direction of the arrow a by the rotation of the platen roller 6b, and the ink sheet 1 is conveyed in the direction of the arrow d by the drive of the reel drive motor on the take-up reel side. be.

Further, in the first embodiment described above, an example was shown in which the U grooves 28b and 28c for positioning the reel bearing 8 were provided on the recording cover 1) side, but the U grooves were provided on the recording cover 1) side.
