Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an ink cartridge used in a thermal transfer recording method and a recording apparatus using the ink cartridge.

<Prior Art> Today, facsimile machines are widely used not only in offices but also in ordinary homes.

In order to facilitate miniaturization of these facsimile machines, a so-called heat-sensitive recording method using a heat-sensitive sheet that develops color when heated is generally used.

However, in recent years, facsimile devices using a so-called thermal transfer recording method using an ink sheet have also been developed.

The facsimile machine using the thermal transfer recording method has the advantage that plain paper or the like can be used as a recording sheet, and images can be recorded clearly.

<Problems to be Solved by the Invention> Since the ink sheet is an extremely thin sheet, wrinkles are likely to occur. Therefore, it is difficult to load the ink sheet into the main body of a recording device without causing wrinkles in the ink sheet. It was time consuming. Therefore, in recent years, a method has been proposed in which the ink sheet is stored in a cartridge and the cartridge is loaded into the main body of the apparatus or replaced.

When the cartridge is loaded into the main body of the recording apparatus and recording is performed, in order to prevent the ink sheet and the recording sheet from skewing, the parallelism between each reel axis of the cartridge and the platen roller provided on the recording apparatus side must be adjusted. However, in the conventional reel shaft, the ink cartridge is positioned and loaded, and in order to position the ink cartridge in the recording device, it is necessary to precisely align the reel shaft and the platen roller shaft. In this method, the reel must be accurately positioned on the ink cartridge, and the ink cartridge must be accurately positioned on the recording device. Therefore, the dimensions and arrangement of each member must be manufactured accurately.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and to improve the positional accuracy of the reel with respect to the printing apparatus by configuring the supply reel and take-up reel of the ink sheet so that they can be directly positioned on the printing apparatus. An object of the present invention is to provide a cartridge and a recording device using the ink cartridge.

<Means for Solving the Problems> A typical means of the present invention for solving the above problems includes a supply reel for supplying an ink sheet, a winding reel for winding up the ink sheet, and a winding reel for winding up the ink sheet. An ink cartridge is configured by providing a bearing rotatably attached to a supply reel and a take-up reel and positioned by a positioning means of a recording device, and a container for holding the bearing. .

<Operation> According to the above means, since the bearing is positioned by the positioning means of the recording device, the supply reel and the take-up reel are directly positioned with respect to the recording device, and the members attached to the recording device It is possible to easily achieve accurate positional accuracy between the reel and the reel.

<Embodiment> Next, an ink cartridge according to an embodiment of the present invention to which the above means is applied and a recording apparatus using the ink cartridge will be described.

, 4b are closed, the engagement recess 4p and the engagement protrusion 4q are engaged to maintain the closed state.

Next, the case where the ink sheet 1 is stored in the container 4 having the above structure will be explained.

As shown in FIG. 1, bearings 8 are fitted to both ends of the supply reel 2 and take-up reel 3 around which the ink sheet 1 is wound, and the bearings 8 are inserted into the U groove 4c of the first housing 4a.

4d respectively. At this time, as shown in FIG. 3, the ink sheet 1 is set so that it is wound from the top to the bottom of the take-up reel 3. )

If you cent the ink sheet 1 as described above,
For example, if the ink sheet 1 is cut, when attaching the tip of the cut ink sheet l to the take-up reel shaft 3a, attach the tip of the ink sheet to the top of the take-up reel shaft 3a using tape 9 or the like as shown in FIG. You can paste it directly.

If this is set so that the ink sheet l is wound up from the bottom to the top of the take-up reel 3, when pasting the cut ink sheet l, the tip of the ink sheet is wound from the bottom of the take-up reel 3, and the tip Take-up reel 3
After reaching the top of the screen, it must be attached with tape 9 or the like.

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, for example during maintenance, the ink sheet 1 cannot be set in the second housing 4b. 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. The engaging recesses 4p and the engaging protrusions 4q of both cylindrical bodies 4a and 4b are engaged.

As shown in FIG. 6, the ink cartridge A having the above structure is provided with a lid 4g at the opening 4f for inserting the recording head, so when transporting or storing the ink cartridge A, the opening 4 is closed.
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 subsequent recording sheets 7 and a discharge roller 15 for discharging eight sheets 7 are provided.

On the other hand, on the recording cover 1) side, as shown in FIGS. 2 and 7 (^), a line-type recording head 6a is attached, which is made up of heating elements 6a1 that generate heat in response to image signals arranged in a line. , when the recording cover 1) is closed, the recording head 6
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 head 6a clamp and position the shaft 6bt 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, a light source 22 irradiates the original surface with light, and the reflected light is reflected by a mirror 23 and a lens 2.
4 to a photoelectric conversion element 25 such as a COD, and in the case of copy mode, transmits the image signal to its own recording system,
In the case of the transmission mode, the configuration is such that the data is transmitted to the recording system of another device.

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
Data for a line is stored. Then, image recording is performed by outputting the data stored in the line memory 50a to the recording head 6a. 5
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. In addition to the CPU 50d, the control unit 50 includes a ROM 50e that stores control programs and various data for the CPU 50d, and a RAM 50f that temporarily stores various data as a work area for the CPU 50d.

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 (NCU).

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

As shown in Figure 7(A), on both sides of the recording cover 1),
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 4C;
U-grooves 28b and 28c are provided at a predetermined interval on the same extension line to fit 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
By locking the ink cartridge A to the locking spring 29, the ink cartridge A is loaded into the recording cup <-1). At this time, the bearings 8 are in 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 lid 4g of the ink cartridge A, as shown in FIGS. 10(A) and 10(B). The recording head 6a is pushed open against the biasing force of the coil spring 41, and thereby the recording head 6a is inserted into the inside of the ink cartridge A from the opening 4r.

Incidentally, when inserting the recording hand drawer a into the opening 4,
The guide pin 4e is provided at the extreme 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 opening 4f is large enough to insert the rad 6a into the recording medium. It is possible to make it approximately equal to the minimum necessary size.

In addition, the biasing force of the lid 4g due to the torsion coil spring 4I (
The force that attempts to return the lid 4g 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 head 6a is operated by a pressing spring 6c.
The pressing force between the platen roller 6b and the platen roller 6b is approximately 150 gf/am.
In contrast, the biasing force of 14 g by the torsion coil spring 41 is set to about 60 gf/cm.

When the ink cartridge A is loaded as described above, the recording head 6a automatically opens the M4g and is inserted into the cartridge A, so that the cartridge A can be easily loaded. Further, since the lid 4g opens in a double-door manner by the pressure of the recording head 6a, the radius of rotation of each lid 4g 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).
(state vA in FIG. 7(B)), close the cover 1), and lock the hook 30a of the apparatus main body IO and the hook 30b of the recording cover 1).

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. Also, 37 is bu.

This is a platen motor for rotating the rotten roller 6b, and the driving force of this motor 37 is transmitted through the gear trains 38a to 3.
It is transmitted to the platen roller 6b via 8c.

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 1)
The driving force transmitting gear 31 is also provided so as to be located on the circular locus of rotation of the J)-Lugya 2C13C centered on J)-Lugia 2C13C.

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 a locked state, the pendulum gear 33e that swings integrally with the driving force transmission gear 31 will not be connected to the parent gear 3.
In order to smoothly swing around the 3d, record cover 1
) can be closed smoothly.

Further, on the apparatus main body lO side, as shown in FIG. 7(B), temporary 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, and the bearing 8 is attached to the U groove 28b of the positioning member 2B by the leaf spring 39.

28c side. For this reason, the bearing 8 is shown in FIG.
As shown in B), the height direction (direction of arrow Z 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. 1θ (B), the pressure contact portion between the recording head 6a and the platen roller 6b is located approximately at the middle of the ink cartridge A in the height direction. When located above the inside, a notch 4 for escaping the shaft of the platen roller 6b shown in FIG.
4 has to be made deeper, and the strength of the second casing 4b becomes weaker (on the contrary, if the pressure contact part is located at the lower part of the ink cartridge A, the opening 4f for inserting the 7d 6a into the recording medium becomes weaker). However, in this embodiment, since the pressure contact portion is located approximately in the middle, the strength of the second casing 4b is not weakened, and the opening 4f can be made as small as possible. It is something that can be done.

Next, the recording device FB loaded with the ink cartridge A
This section describes the case where recording is performed using .

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. At the same time, the heating element 6a of the recording head 6a
I generates heat in response to an image signal and heats 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 is configured such that the circumferential rotational speed of the take-up reel 3 is lower 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. It is driven to become slightly faster, and the faster speed is absorbed by the slip clutch 35. As a result, the ink sheet 1 is wound around the winding wheel 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
5 and rotates as the ink sheet 1 is fed out. This sliding load imparts pack tensile strength to the ink sheet 1.

In addition, in FIG. 12, the ink sheet 1 is
When the front tension run when the sheet 1 is wound up causes a strong force to press the recording pad 6a upward,
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 head 6a 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 4n of the ink cartridge A is released and the grip 4n of the ink cartridge A is grasped and pulled, the engagement between the locking protrusion 4n of the ink cartridge A and the locking spring 29 is released, and the ink cartridge is opened as shown in FIG. 7(A). A rotates around the guide pin 4e and can be easily removed from the recording cover 1).

At this time, since both the handle 40 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 projection 4q. Therefore, when the locking projection 4n is removed from the locking spring 29, the first housing 4a and the second housing 4b are opened. It won't happen.

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 is the same as that of the first embodiment, except that the supply reel 2 and take-up reel 3 are reversed.

In addition, in this configuration, the take-up reel 3 - the lugia 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 may also be provided on the apparatus main body lO side. good.

For example, as shown in FIG. 14, U grooves 40a, 40 for positioning the bearings 8 of the supply reel 2 and take-up reel 3
b is installed at a predetermined position on the apparatus main body lO, and a guide pin 4e for holding the ink cartridge A mentioned above is installed on the recording cover 1) side.
A positioning member 41 having only a key-shaped groove 41a for positioning is provided, and a locking spring 29 for locking with the locking protrusion 4n of the ink cartridge A is provided.

Therefore, the ink cartridge A is attached to the recording cover 1) by fitting the guide pin 4e into the key-shaped groove 41a and locking the locking protrusion 4n with the locking spring 29 in the same way as in the embodiment described above. Next, when the recording cover 1) is closed, the bearings 8 are fitted into the U grooves 40a, 40b provided in the main body 10 of the apparatus and positioned, as shown in FIG.

In FIG. 15, reference numeral 42 indicates a pressing spring attached to the U grooves 40a and 40b, and when the recording cover 1) is closed, the upper end of the bearing 8 is pressed against the contact portion 41b of the positioning member 41.
It is brought into contact with the

If the means for positioning the bearing 8 is provided on the apparatus main body 10 side to which the platen roller 6b is attached as described above, the reel 2.3 positioned by the U grooves 40a, 40b and the platen roller 6b It is easy to achieve parallelism with high accuracy.

Further, as in the first embodiment described above, even if the reel gears 2c and 3c are pressed upward as shown in FIG. 15 by the driving force transmission gear 31 when transmitting the driving force to the reel 2. Since the tooth contacts the contact portion 41b and does not move in the height direction, so-called tooth skipping does not occur.

<Effects of the Invention> As described above, in the present invention, since the bearings of the supply reel and the take-up reel around which the ink sheet is wound are directly positioned and loaded into the positioning means of the recording device, the members provided on the recording device side are It is possible to easily improve the positional accuracy between the reel and the reel.
