Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transfer paper cartridge that is installed in a recording apparatus that records using transfer paper.

[Prior Art and its Problems] In a recording apparatus using transfer paper, the ink on the transfer paper is lost during transfer recording, so the transfer paper must be replaced as necessary.

In addition, since recording paper is also consumed, it must be replenished at an appropriate time.

In order to smoothly replace the transfer paper and replenish the recording paper, a transfer paper cartridge has been proposed that integrates a transfer paper storage section for storing the transfer paper and a recording paper storage section for storing the recording paper. There is.

In other words, when replenishing recording paper or replacing transfer paper, check the consumption status of the other paper, and if it is already consumed, prepare it in advance, and these operations will be carried out smoothly and the recording paper or This makes it possible to avoid unexpected situations such as not having transfer paper on hand.

However, the transfer paper cartridge in which the transfer paper storage section and the recording paper storage section are integrated is quite large.
Therefore, when replacing the transfer paper and replenishing the recording paper, a large amount of force is required to attach and detach the transfer paper cartridge to and from the main body of the recording device, which reduces work efficiency.

Furthermore, since the transfer paper must be placed between the thermal head and the platen roller, the transfer paper cartridges that have been proposed so far to meet this requirement have a transfer paper storage section and a recording paper storage section. Even if it is a separate structure, it is large, and therefore, the conventional recording 5A main body has the disadvantage of being inevitably large. Furthermore, there is a drawback that the quality of printing deteriorates when dirt or dust adheres to the ink surface of the transfer paper.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned problems, and includes a method of storing a wound transfer paper between a transfer paper roll on a supply side and a transfer paper roll on a winding side, It is integrally composed of a transfer paper storage section located at the front side in the insertion direction and a recording paper storage section that stores recording paper. A transfer paper cartridge adapted to be pulled out, wherein the transfer paper is wound around both of the transfer paper rolls so that the ink surface thereof is positioned downward when the rolls are pulled out. The company provides paper cartridges.

[Embodiment] FIG. 1 is a perspective view showing an embodiment of a transfer paper cartridge according to the present invention, FIG. 2 is a perspective view of the transfer paper cartridge installed in a recording device, and FIG. 3 is a perspective view of the recording device. FIG. 3 is a side view illustrating the operation.

In each figure, 1 is a transfer paper cartridge, and this transfer paper cartridge 1 is configured to not only store transfer paper but also record paper, that is, it has a transfer paper storage section 2 and a recording paper storage section. Part 3 is integrated.

4.5 is a part of the inner wall of the transfer paper storage section 2, that is, a part of the side surface extending in the insertion direction, in order to mount the transfer paper roll.
These grooves are arranged at intervals of L so as to be perpendicular to the insertion direction, and in all four of these grooves, both ends of the supply side roll 7 of the transfer paper 6 are disposed, and in the groove 5, Both ends of the roll 8 on the winding side of the transfer paper 6 are provided.

Note that the transfer t4t6 is transferred to the supply side roll 7 and the take-up side roll 8.
In the state in which the transfer paper 6 is wound, even if they are arranged at a full width of 4.5 mm, there is a distance L between the center axes of the supply roll 7 and the take-up roll 8, so the transfer paper 6 does not come into contact with each other. There's nothing to do. However, within a range that satisfies such conditions, Φ is set to a minimum value.

In addition, when the transfer paper 6 is wound around the supply roll 7 and the take-up roll 8, there are some gaps between the both ends of the transfer paper 6 and the inner walls on both sides of the transfer paper storage section 2. The lengths of the supply side O-luer and the winding side roll 8 in the axial direction are set so that there is a gap, that is, there is enough room for a lever 16 to be described later to enter this gap.

Reference numeral 9 denotes a winding-side O-ru 8 on which both ends of the transfer paper storage section 2 of the transfer paper cartridge 1 are arranged.
It is an opening formed by removing the side surface perpendicular to the insertion direction of the transfer paper cartridge 1 facing the front side when the transfer paper cartridge 1 is inserted into the recording apparatus main body, and is an opening formed by removing the front surface when the transfer paper cartridge 1 is inserted into the recording apparatus main body. This is to enable the lever 16 to enter into the transfer paper storage section 2 through the opening 9.

Reference numeral 11 denotes a platen roller built into the main body of the recording apparatus, and the platen roller 11 is attached to a shaft 12, and rotates when the shaft 12 receives rotational force from a motor 13 via gears 14 and 15. It is configured like this.

When the lever 16 enters the transfer paper storage section 2 through the opening 9 of the transfer paper cartridge 1, a U-shaped notch 17 is formed at the tip end of the lever 16 so that the take-up roll 8 can be held. It is formed.

18 is a gear fixed to the side of the lever 16, and this gear 18 transfers the rotational force from the motor 19 to the gears 20 and 21.
The lever 16 is configured to rotate around the shaft 12 by being received through the lever 16, thereby rotating the lever 16.

Note that 22 is a shaft attached to the gear 21.

23 is a protrusion provided at a predetermined position on the lever 16, and this protrusion 23 is connected to a detection means 24 provided at a predetermined position.
25, and the protrusion 2 of the lever 16
3 is detected by the detection means 24, 25, the motor 19 stops its rotation and the driving of the lever 16 is stopped.

26 is a thermal head disposed with respect to the platen roller 11, and this thermal head 26 is connected to the lever 16.
That is, the lever 16 is activated in response to the operation of the motor 1.
While operating by the force of 9, it retreats away from the platen roller 11 as shown by the dotted chain line in FIG.
During recording, a drive IJJI structure (not shown) for the thermal head 26 is provided so that it can be pressed against the platen row 511 as shown by the dashed dotted line in FIG.

27 is a gear for applying a rotational force in the transfer paper winding direction to the take-up roll 8 set at a predetermined position from inside the transfer paper cartridge 1 by the operation of the lever 16; It is designed so that it can mesh with the gear 28 disposed on the gear 28, and in this meshed state, the gear 28
When a driving means (not shown) for 7 is operated, the take-up roll 8 rotates as transfer recording progresses, and the used transfer paper 6 is wound onto the take-up roll 8.

The gear 28 is disposed on the take-up roll 8 when the lever 16 reaches the position indicated by the double-dashed line in FIG.

Further, 29 is a bearing member for the winding side roll 8,
This bearing group 11129 is also disposed on the winding-side roll 8 in the same manner as the gear 28.

Next, the operation of the recording device using the transfer paper cartridge according to the present invention having the above structure will be explained.

First, the supply roll 7 with the transfer paper 6 wound thereon is placed in the groove 4, the take-up roll 8 is placed in the groove 5, and the recording paper (not shown) is placed in the groove 4.
The transfer paper cartridge 1 which is arranged in the recording paper storage section 3,
Insert it into the record If in the direction of the arrow in FIG. Then, the lever 16 enters into the transfer paper storage section 2 through the opening 9, and the take-up side circle 8 fits into the U-shaped notch 17 at the tip of the lever 16.

After this, when a switch (not shown) is turned on, or the second
When it is detected that the take-up roll 8 is fitted into the U-shaped notch 17 at the tip of the lever 16 which is in the solid line position in the figure, the motor 19 is activated and the gear 20 is moved in the opposite direction in FIG. Clockwise and gear 21 is rotated clockwise, which in turn causes gear 18 to be rotated counterclockwise. As a result, the lever 16 is rotated counterclockwise, and the U-shaped notch 17
The take-up roll 8 held by the lever 16 is set in a predetermined position from the transfer paper storage section 2 through the process shown in FIG. 3 by the operation of the lever 16.

That is, as the lever 16 rotates, the lever 1
When the protrusion 23 provided on the lever 6 reaches the position where the detection means 24 is activated, the motor 19 stops its operation, and the lever 16 is moved to its normal position (see FIGS. 2 and 3).
The gear 2 is stopped at the lever position shown by the plate point glIiI in the figure), and the gear 2
8 is provided, and this gear 28 meshes with gear 27 to set it in a predetermined position.

Incidentally, while the lever 16 is in operation, the thermal head 26 is retracted to the position shown by the dotted chain line in FIG.
Transfer paper 6 in the darkness between supply side roll 7 and take-up side roll 8
is positioned between the platen roller 11 and the thermal head 26 so that it does not get in the way, so after the lever 16 is stopped, the thermal head 26 is moved relative to the platen roller 11 by the drive l1 mechanism of the thermal head 26. It approaches the position shown by plate point III in FIG. 3, and is ready to start transfer recording. That is, after this, a monthly recording report (not shown) is fed onto the platen roller 11 from the bottom side of the recording paper storage section 3 by a predetermined means (not shown).
Then, the thermal head 26 presses the recording paper and the transfer paper 6 between them to the platen row 511, and sends a predetermined signal to the thermal head 26. IfR is sent to thermal head 2
6 generates heat, the ink on the transfer paper 6 is transferred to the recording paper, and printing is performed. During printing as shown in Figure 3, the transfer paper is passed from above between the platen roller and the thermal head with the ink side facing down, so dirt and dust will not adhere to the ink side. It is possible to perform high-quality printing without any problems.

In addition, if the transfer paper 6 is wound up by the winding roll 8 and you want to change it to a new transfer paper 6, turn on the unloading switch (not shown) or the transfer paper will end. When this is detected, the operation is opposite to that in the above case, that is, the motor 19 rotates in the opposite direction to that in the above case, and the lever 16 is moved clockwise in FIG. 2 (counterclockwise in FIG. 3). The take-up roll 8, which rotates and is held by a U-shaped notch 17 at the tip of the lever 16, is shown in FIGS.
It is located at the position shown by the solid line in the figure, that is, in the groove 5 in the transfer paper storage section 2 of the transfer paper cartridge 1.

Incidentally, at this point, the protrusion 23 provided on the lever 16
actuates the detection means 25, so that the motor 19 stops its operation and the lever 16 also stops its operation.

Therefore, after this, by pulling out the transfer paper cartridge 1 in the direction of arrow B in FIG. 2, the transfer paper 6 can be replaced.

At this time, recording paper is also replenished as necessary.

In the above embodiment, the case where the winding side roll 8 is held and transferred by the lever 16 has been described, but the supply side roll 7 may be held and transferred by the lever 16. However, in this case, since the take-up side roller 8 is held within the transfer paper cartridge 1,
The gear 27 must also be provided at a corresponding position.

Furthermore, in the above embodiment, the case where the transfer paper storage section 2 and the recording paper storage section 3 are integrally structured is described as a transfer paper cartridge, but the transfer paper storage section 2 and the recording paper storage section are separate structures. There is no problem even if it is a transfer paper cartridge. That is, as shown in FIG. 4, on both side walls of the transfer paper storage section 2,
A groove 5 is provided for arranging both ends of the supply roll and a groove 5 is provided for arranging both ends of the take-up roll, and the front side of the transfer paper cartridge 1 ridge 1 is removed. Alternatively, the opening 9 may be formed.

Also, the full 4.5 is not the type that stops midway,
It is formed so that it extends to the top and bottom ends of both side walls of the transfer paper storage section 2, and an inverted Ω-shaped resilient material is provided in the middle, and the supply side roll is 7. Both ends of the winding roll 8 may be supported.

[Effects of the Invention] The transfer paper cartridge according to the present invention stores the transfer paper wound between the transfer paper roll on the supply side and the transfer paper roll on the take-up side, and stores the transfer paper wound on the transfer paper roll located at the front side in the insertion direction. A storage section and
When one of the rolls is pulled out by the pull-out means when installed in the apparatus, when one of the rolls is pulled out by the pull-out means,
Since the transfer paper is wound around both transfer paper rolls so that the ink side of the transfer paper is on the lower side, it prevents dirt and dust from adhering to the ink side, resulting in high-quality printing. It is possible to perform stable printing at the same time.

In addition, since the cartridge is an integrated structure of the transfer paper storage section and the recording paper storage section, the cartridge can be made smaller, and therefore, when replacing the transfer paper, it is easier to remove the transfer paper cartridge from the main body of the recording apparatus. The transfer paper replacement work becomes easier, and since the transfer paper cartridge is smaller, the storage space required for the transfer paper cartridge in the main body of the recording apparatus can be reduced, and the recording apparatus can be made smaller.
