Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an ink sheet cartridge cartridge equipped with an ink sheet and a recording apparatus using the ink sheet cartridge.

Here, the recording device includes a printer, an electronic typewriter, a word processing sensor, a copying machine, a facsimile machine, and the like.

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

These facsimile machines are designed to facilitate miniaturization.
A so-called thermal recording method using a thermal sheet that develops color when heated is generally used.

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

In the facsimile device using the thermal transfer recording method, plain paper or the like can be used as the recording sheet, and
It has the advantage of being able to record images clearly. <Problems to be Solved by the Invention> However, since the ink sheet is an extremely thin sheet, wrinkles are likely to occur. Therefore, it takes time and effort to load the ink sheet into the main body of the recording apparatus without causing wrinkles on the ink sheet. Therefore, in recent years, a method has been proposed in which the ink sheet is stored in a cartridge nozzle and the cartridge nozzle is loaded into the main body of the apparatus or replaced.

However, when loading the cartridge into a recording device, it must be positioned and loaded accurately due to the relationship with the recording head and platen roller provided in the recording device. Therefore, there have been problems such as a complicated positioning mechanism for the ink sheet cartridge with respect to the recording apparatus.

Furthermore, the ink sheet cartridge container must have an opening at a predetermined position for inserting an ink cartridge into the recording medium. Therefore, the ink sheet is exposed from the opening. For this reason, there are problems in that dust or the like that enters through the openings may adhere to the ink sheet or damage the exposed ink sheet.

On the other hand, when the ink sheet cartridge cartridge is loaded into a printing apparatus and printing is performed, driving force must be transmitted to a take-up reel in order to wind up the ink sheet being conveyed. Therefore, it is necessary to reliably connect the take-up reel in the removable cart reel with the drive transmission system of the device main body, which poses a problem in that the configuration for this purpose becomes complicated.

Furthermore, when recording is performed using the ink sheet cartridge cartridge, the ink sheet and the recording sheet are conveyed between the recording head and the platen roller, and the heating element of the recording head is selectively heated, thereby increasing the temperature of the ink sheet. Thermal transfer recording is performed by transferring the ink contained in the recording sheet onto a recording sheet. However, if the recording head does not press the platen roller with a constant force at this time, image omission may occur.

On the other hand, the ink sheet cartridge conveys the ink sheet while applying tension to the ink sheet so as not to wrinkle the ink sheet conveyed from the supply reel to the take-up reel during recording. Therefore, the tension of this ink sheet may force the recording head in the opposite direction to the direction in which it presses the platen roller. Therefore,
The pressing force between the recording head and the platen roller changes,
There were problems such as the inability to record high-quality images in some cases.

Furthermore, with conventional ink sheet cartridges, it is troublesome to load the ink sheet into the cartridge.
Alternatively, if the ink sheet is cut in the middle, there is a problem that it is troublesome to connect the sheet to the take-up reel.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and provide an ink sheet cartridge that can accurately position an ink sheet cartridge with respect to a recording device when loading the ink sheet cartridge into the recording device, and a recording method using the ink sheet cartridge. The goal is to provide equipment. Another object of the present invention is to provide an ink sheet cartridge and an ink sheet cartridge that can be reliably connected to a drive transmission system of an apparatus main body to receive driving force when the ink sheet cartridge is loaded into a recording apparatus. The purpose of the present invention is to provide a recording device for use in the present invention.

Still another object of the present invention is to provide an ink sheet cartridge capable of recording high-quality images and a recording apparatus using the ink sheet cartridge.

Still another object of the present invention is to provide an ink sheet cartridge that has a simple configuration, can be accurately positioned in the main body of the apparatus, and can perform good recording, and a recording apparatus using the ink sheet cartridge. be.

Means for Solving the Problems> A representative means of the present invention for achieving the above object is an ink sheet cartridge that is equipped with an ink sheet and can be loaded into a recording device that records on a recording medium. a frame body for supporting a first winding member capable of winding the ink sheet, a first winding member capable of winding the ink sheet, the first winding member and the second winding member; and a guide protrusion protruding outward from the frame body for guiding when loading into a recording device, forming an ink sheet cartridge, and when loading into a recording device, the first A positioning member for positioning the winding member and the second winding member in the device is provided.

The ink sheet is also configured to be guided by the tension of the ink sheet wound from the first winding member to the second winding member so that an urging force does not act on the recording means provided in the recording device. .

Further, a driving force receiving portion is provided in each of the first winding member and the second winding member, and the rotation locus of the driving force receiving portion when the ink sheet cartridge is loaded into the recording cover and the cover is rotated. A driving force transmission means is provided on a circle.

<Operation> In the above means, when loading the ink sheet cartridge into the recording apparatus, accurate positioning is performed by the positioning member.

Furthermore, even if tension is applied to the ink sheet during recording, the tension does not affect the recording means of the recording device. Therefore, it becomes possible to record high-quality images.

Furthermore, load the ink sheet cartridge into the recording cover,
Since the driving force transmitting means is provided on the rotation locus circle of the reel gear when the cover is rotated, when the recording cover is rotated, the reel gear meshes with the driving force transmitting means reliably.

Note that when the recording cover 11 is closed, the fork members 6d attached to both ends of the recording head 6a touch the platen roller 6.
The recording head 6a is positioned with respect to the platen roller 6b by sandwiching and holding the shaft 6b+ of the shaft 6b.

Furthermore, the configuration of the image reading system C is such that a plurality of originals 17 can be stacked and placed on an original placing table l6 formed on the upper surface of the recording cover 11. Then, the plurality of originals 17 placed on the mounting table 16 are pre-loaded by the pre-aS feed roller 18a and the pressing roller 18b.
At the same time as being conveyed, the sheets are 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. Then, in order to read the image with a reading unit 60, which will be described later, the original 1

In this case, it is transmitted to its own recording system. Furthermore, 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.

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

The configuration will be specifically explained. In FIG. 8, the reading system C includes the aforementioned photoelectric conversion element 25, a drive motor 56 for the pre-transport roller 16, the pair of transport rollers 20a and 20b, and the like. The line memory 50a in the control unit 50 stores image data of each line of image data.

The recording system 51 includes the recording head 6a described above and motors (reel drive motor 32 and platen motor 37) described later.
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. Furthermore, 53 is a display section for displaying various functions provided in the operation section 52, the status of the device, and the like. Also, 54 is a modem (
55 is a network control unit (NCU).

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

As shown in FIG. 7(a), on both sides of the recording cover 11,
A positioning member 28 formed laterally symmetrically is attached. This positioning member 28 has a key-shaped groove 2 for locking the guide pin 4e of the ink sheet cartridge A.
8a, and U grooves 28b and 28c for fitting and positioning the bearing 8 fitted to both ends of the reel 2.3.
are integrally provided at a predetermined interval on the same extension line. Further, a locking spring 29 for locking the locking protrusion 4n of the ink sheet cartridge A is provided near the open end of the recording cover 11.

Therefore, when loading the ink sheet cartridge A into the recording cover 11 of the apparatus main body 10, as shown in FIG. guide the groove 28a2 along the slope 28a+ of the groove 2832.
Insert and lock. Then, the ink sheet cartridge A is rotated around the guide pin 4e fitted into the key-shaped groove 28a, and the locking protrusion 4n is locked to the locking spring 29 as shown in FIG. 7(b). Sheet cartridge A is loaded into recording cover 11. At this time, bearing 8
are fitted into the respective U grooves 28b and 28c.

Here, in the loaded state, a line connecting the center of the guide pin 4e of the ink sheet cartridge A and the center of the bearing 8 fitted in the U groove 4c to 4d (Fig. 7 et al.), a dotted line l in Fig. 10(b) ) so that it becomes almost a straight line.
, a bearing 8 and U grooves 4c and 4d are arranged. For this reason, when the ink sheet cartridge A is rotated about the guide pin 4e, the bearings 8 of the supply reel 2 and the take-up reel 3 are inserted into the U groove 28b of the positioning member 28. 28c
They are fitted and positioned almost simultaneously. Therefore, there is no risk that one of them will fit first and become the center of rotation, and the bearing 8 can be reliably positioned with respect to the U grooves 28b, 28c of the positioning member 28. .

Furthermore, in this embodiment, the guide pin 4e and the U groove 4c into which the bearing 8 is fitted are provided. 4d are both provided on the first housing 4a side. Since the center of the guide pin 4e and the arc centers of the U grooves 4c and 4d are arranged approximately in a straight line (in this embodiment, the U grooves 4c and 4d hold the bearing 8 by approximately 2 to 3
The grooves 28a of the key-shaped grooves 28a formed in the member 28 for positioning these are not perfectly straight because they are configured to fit with play (backlash) of m.
By arranging the arc centers of U grooves 28b and 28c substantially in a straight line, the bearing 8 is accurately positioned with respect to the guide pin 4e. That is, the key-shaped groove 28a
or U groove 28b. 28c is the same member as positioning member 2
With a simple configuration of placing the bearing 8 approximately in line with the
It is possible to obtain high positional accuracy when positioning.

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

Furthermore, when loading the ink sheet cartridge A as described above, as shown in FIGS. 10(a) and (b), the fork member 6d attached to the recording head 6a is twisted and pushed open against the biasing force of the coil spring 41, whereby the recording head 6a enters the inside of the cartridge A through the opening 4f of the ink sheet cartridge cartridge A.

Furthermore, since the opening 4f is provided approximately at the center between the reels 2 and 3, the lid 4g pushed open by the fork member 6d attached to the recording head 6a has a simple planar shape and can be used for both reels 2, 3. The ink sheet 1 can be configured so as not to come into contact with the ink sheet 1 wound around the ink sheet 3, increasing the degree of freedom in design. Also, the opening 4f is approximately determined by the recording head 6a and the fork member 6d.
The ink sheet cartridge A can be made compact by narrowing the interval between the reels 2 and 3 and reducing the wasted space between the recording head 6a and the reels 2 and 3 as much as possible.

Incidentally, when inserting the recording head 6a into the opening 4r,
The guide pin 4e is provided at the end of the ink sheet 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 by the size of the recording head. It is possible to make the size approximately equal to the minimum size necessary for inserting 6a.

Also, the biasing force of the lid 4g due to the torsion coil spring 4l (
The force that attempts to return the lid 4g to the closed state) is shown in Figure 1O (b
), insert the recording head 6a and insert the throat 6 into the cough.
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/cm.
On the other hand, the torsional recoil bar, f(4
The biasing force of the lid 4g due to i is set to approximately 60 gf/cm.

When the ink sheet cartridge A is loaded as described above,
Since the recording throat 6a automatically opens the lid 4g and is inserted into the ink sheet cartridge A, the ink sheet cartridge cartridge A can be easily loaded. Further, since the lid 4g opens in a double-folding manner by the pressure of the recording head 6a, the turning radius of each lid 4g is small, and the length of the ink sheet cartridge 7A in the height direction can be shortened.

Attach the ink sheet cartridge A to the recording cover 11 as described above (the state shown in FIG. 7(C)), and then close the cover 1.
1, and then remove the hook 30a of the device main body lO and the recording cover 1.
1 and 30b to close the device.

At this time, reel gears 2c and 3c integrally formed with the supply reel 2 and the take-up reel 3 constitute a driving force transmission gear 31 that constitutes a driving force transmission means attached to the device main body 10 side.
It is configured to mesh with the

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 lO side of the recording apparatus B, and the motor 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 the gear shaft 3 of the gear 33d.
The arm 34 is attached to an arm 34 that can rotate around the gear 4a, and is configured as a so-called pendulum gear that can swing around the gear 33d while being engaged with the gear 33d. 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.

In addition, numeral 36 in FIG. 7 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 11 is closed, the reel gears 2c and 3c exposed from the opening 4m of the ink sheet cartridge A come to mesh with the driving force transmission gear 31. In this embodiment, the opening 4m is as shown in FIG. 11(a). As shown in (b), the recording cover 11
The reel gears 2c and 3c are provided so as to be located on the rotation locus circle around the hinge shaft 12, and the driving force transmission gear 31 is also provided so as to be located on the locus circle. Therefore, when the recording cover 11 is closed, the gears 2c and 3c exposed from the opening 4m are transferred to the driving force transmission gear 3.
Press 1 to ensure engagement. At this time, even if the parent gear 33d connected to the motor 32 is in a locked state,
A pendulum gear 33e that swings integrally with the driving force transmission gear 31
Since it swings smoothly around the main gear 33d, the recording cover 11 can be closed smoothly.

Further, as shown in FIG. 7(b), on the apparatus main body IO side, temporary springs 39 serving as pressing members are attached at positions facing the bearings 8 of the ink sheet cartridge A attached to the recording cover 11. The plate spring 39 presses the bearing 8 toward the U grooves 28b and 28c of the positioning member 28. Therefore, the bearing 8 is reliably positioned in the height direction (direction of arrow Z in FIG. 7(b)) as shown in FIG. 9(b). In addition, the plate holder 39 is shown in Fig. 9 (
b), the U groove 28b of the positioning member 28. 2
It is attached so as to coincide with the reel 8c in the axial direction. For example, the plate spring 39 and the positioning member 28
If they do not match in the reel axial direction, torsional force will be applied to the bearing 8, and unnecessary frictional force will be applied to the rotation of the reel 2.3. However, in this embodiment, Otherwise, the above-mentioned inconvenience will not occur.

As described above, the bearing 8 is inserted into the U groove 28b of the positioning member 28.
．． Positioned at 28C, ink sheet cartridge A
Positioning when loading the recording cover l1 and bearing 8
It is configured independently of the positioning with respect to the recording device WB. That is, the bearing 8 is connected to the ink sheet cartridge A.
By directly positioning the reels 2 and 3 to the recording device B without going through the media, it is possible to improve the accuracy of the parallelism between the reels 2 and 3 and the platen roller 6b. Furthermore, since the ink sheet cartridge A does not require strict positional accuracy of the bearing 8, there is no need to require the ink sheet cartridge A to have rigidity or accuracy. Therefore, the ink sheet cartridge A can be manufactured at low cost.

Further, in this embodiment, when the recording cover 11 is closed,
As shown in FIG. 10(b), the pressure contact portion between the recording head 6a and the platen roller 6b is located approximately in the middle of the ink sheet cartridge A in the height direction. If the pressure contact portion is located above the ink sheet cartridge A, the notch 12 for escaping the shaft of the platen roller 6b shown in FIG. 1 must be made deep, which weakens the strength of the second housing 4b. Conversely, if the pressure contact portion is located at the lower part of the ink cartridge A, the recording head 6
The opening 4f for inserting the opening 4f must be made large. However, in this embodiment, since the pressure contact portion is located approximately at the center, the strength of the second casing 4b is not weakened, and the opening 4f can be minimized.

Next, a case will be described in which printing is performed using the printing apparatus B loaded with the ink sheet 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 set in the long state. 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 1 superimposed thereon in the directions of arrows b and c, respectively. In synchronization with this, the heating element 6a+ of the recording head 6a generates heat in response to 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 is configured such that the rotation peripheral speed of the take-up reel 3 is lower than the rotation peripheral speed of the platen roller 6b so that the ink sheet 1 conveyed by the platen roller 6b does not slacken. The motor is also driven slightly faster, and the faster speed is absorbed by the slip clutch 35. 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 of the two supply reels is locked, the supply reel 2 does not have a slip clamp 3.
It receives a sliding load of 5 and rotates as the ink sheet l is fed out. This shearing load applies tension to the ink sheet 1. In FIG. If the force pressing the recording head 6a upward is strong, the pressing force of the recording head 6a against the platen roller 6b changes, and in extreme cases, image omission may occur.

However, in this embodiment, the ink sheet 1 after recording is guided by a guide shaft 4k located below the recording position R where the recording head 6a presses the platen roller 6b. Therefore, the ink sheet l after passing through the recording position R is at least once at the recording position R.
Since the ink sheet 1 is guided further downward, 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 pressing force of the recording head 6a against the platen roller 6b is always constant, and there is no risk of image omission or the like. As described above, the guide shaft 4k may be provided on the ink sheet cartridge A or on the recording cover 11 side.

Further, as shown in FIG. 12, the lug gear 2c of the two supply reels receives an upward force due to the driven rotation of the driving force transmission gear 31 which is subjected to a helical load. Since it is supported by the bearing 8, the bearing 8 does not move upward. That is, reel gear 2c. Since the U grooves 28b and 28c are installed so as to restrict the direction in which the reel gears 3c are urged by the driving force transmission gear 31, the reel gears 2c and 3c do not move.
, between the gears 2c, 3c and the driving force transmission gear 31,
This prevents so-called tooth skipping.

Next, the case where the ink sheet cartridge A is replaced or removed from the recording cover 11 will be explained.

In this case, as shown in FIG. 7(b), the recording cover 11
When the handle 4o of the ink sheet cartridge A is released and the handle 4o of the ink sheet cartridge A is released, the engagement between the locking protrusion 4n of the ink sheet cartridge A and the locking spring 29 is released, and the state shown in FIG.
), the ink sheet cartridge A rotates around the guide pin 4e and can be easily removed from the recording cover 11. At this time, the handle 4o and the locking protrusion 4n
are both provided on the second housing 4b side, so even if the handle 4o is pulled, the engagement between the first housing 4a and the second housing 4b, that is, the engagement between the engagement recess 4p and the engagement protrusion 4q, will not occur. No force is applied to the joint. Therefore, when removing the locking protrusion 4n from the locking spring 29, the first housing 4a and the second housing 4
b will never open.

As mentioned above, the ink sheet cartridge A according to this embodiment is used in the recording apparatus B to which the recording head 6a is attached.
It can be loaded easily and with high positioning accuracy, and can prevent gear tooth skipping in the drive transmission system and perform high-quality recording.

In this case, the structure of the ink sheet 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 slithop 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 l is conveyed in the direction of the arrow d by the drive of the reel drive motor on the take-up reel side. It is something. A sliding clutch 35 is provided in the gear train that transmits the driving force to the reel gear 2c of the supply reel 2, and the reel 2 receives a sliding load, and this sliding load applies pack tension to the ink sheet 1. .
