Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel subcassette. More specifically, the present invention relates to a sub-cassette that allows endless ink ribbon (hereinafter referred to as endless ribbon) to be easily filled into a ribbon cartridge case (hereinafter referred to as cartridge case) that is attached and fixed to various printers.

Traditionally, when replacing the endless ribbon in a cartridge case, filling a new endless ribbon has been done by, for example, distributing the endless ribbon from side to side, filling it densely into a box-shaped case, and then using your fingers. The method used is to take the cartridge out of the case while holding both folded ends and store it in the cartridge case. When the endless ribbon is stored, the fingers pressing down on both ends of the folded endless ribbon come into contact with the inner walls of the case, making the filling process extremely difficult, and also staining hands and causing the ribbon to fall down, causing ribbon feeding failures. There are drawbacks such as

There is a sub-cassette described in Japanese Utility Model Application Publication No. 116004/1983 that has been devised to overcome these drawbacks. As shown in FIG. 5, this sub-cassette has a through hole 13 about the thickness of a finger in the bottom surface 11 of the case body 1, and an endless ribbon 2 is housed in the case body 1 via an insole 3. It is something. When filling the cartridge case with the endless ribbon 2, as shown in FIG. 6, insert a finger into the through hole 13, press the insole 3, and pull out only the case body 1 upward.

However, when pulling out the case body 1, if you do not press your finger on the edge of the through hole 13 and lift it straight up, your finger will move and end up disrupting the alignment of the endless ribbon 2. Also, if you apply force to your fingers to prevent this from happening, your fingertips will become tense and may disrupt the alignment of the endless ribbons 2.

As described above, in the conventional sub-cassette shown in FIG. 5, the removal of the case body 1 requires great care and is more difficult than expected.

In view of the above circumstances, it is an object of the present invention to provide a sub-cassette which allows filling of endless ribbon into a cartridge case with ease and with rough operations.

The subcassette of the present invention will be explained in detail below with reference to the drawings.

Fig. 1 is a schematic perspective view showing an embodiment of the sub-cassette of the present invention, Fig. 2 is a schematic sectional view taken along the line A-A in Fig. 1, and Fig. 3 is a schematic perspective view showing an example of the case main body of the present invention. 4 is a schematic cross-sectional view showing a cartridge case filled with endless ribbon using the sub-cassette of the present invention.

As shown in FIGS. 1 to 3, the sub-cassette of the present invention consists of a case body 1 and an endless ribbon 2 that is closely housed within the case body 1.
The case body 1 has a rectangular bottom surface 11 and side plates surrounding the four sides, and is a box-shaped container with an open top surface, and the endless ribbon 2 is accommodated in the case body 1 via an insole 3. . A linear folded part 4 is provided from one long side of the bottom surface 11 of the case body 1 to the other long side opposite to the long side, and the case body 1 continues from both ends of the folded part 4.
Cut portions 5a and 5b are provided in the side plates of.

As shown in FIG. 1, the endless ribbons 2 are housed in the case body 1 in a non-oriented and dense manner, but if necessary, they can be housed in the case body 1 so as to be distributed left and right. The endless ribbon 2 is inserted into the case body 1 through slit-shaped openings 6a and 6b formed in the mutually opposing side plates of the case body 1 from the upper end to the bottom surface.
contained within.

To fill the endless ribbon 2 into the case body 1, for example, at least one side plate 12 of the case body 1 is configured to be openable and closable, and the side plate 12 is opened and the endless ribbon 2 is filled into the case by a filling machine (not shown). It is sufficient to fill the main body 1, then close the side plate 12 and fix it to the case main body 1.
Opening and closing of the side plate 12 can be easily achieved by forming one side end 12a of the side plate 12 so that it can be folded back.

Next, the filling operation of the endless ribbon 2 collected in the case body 1 into the cartridge case 7 will be explained.

First, the case body 1 is placed in the ribbon storage section 71 in the cartridge case 7 with the case body 1 facing downward. Next, when one side 1a of the case body 1 is picked up with fingers, that part 1a is bent at the folded portion 4 and lifted. At this time, the insole 3 may be lightly pressed by inserting a finger under the lifted portion 1a. Next, pinch the remaining portion 1b of the case body 1 with your fingers and lift it up. It is best to gently remove the insole 3 after the case body 1 is taken out as described above.

In this way, the endless ribbon 2 is filled into the ribbon storage section 71 of the cartridge case 7.

In the present invention, when taking out the case body 1, it is possible to insert a finger under one side 1a of the lifted case body 1 as shown in FIG. I can't stand it. Also case body 1
When you pick up something, you don't have to lift it straight up; you can lift it a little diagonally, front and back, left and right, and after lifting it slightly upwards, you can also move it almost straight to the side.

In this way, in the present invention, since the movement path when taking out the case body 1 can be freely chosen,
The operation can be performed very roughly without requiring much attention.

Therefore, the fingers pressing down on the insole 3 touch the case body 1.
When taking out the endless ribbon 2, the endless ribbon 2 will not be moved unexpectedly or strained more than necessary, so the aligned state of the endless ribbon 2 will not be disrupted. Also case body 1
The case body 1 can be lifted while expanding the inner diameter in the longitudinal direction, so even if you do not necessarily press the insole 3 with your fingers, the insole 3 remains on the endless ribbon 2, and the inner diameter of the case body 1 is lifted. It is possible to prevent the endless ribbon 2 from falling down and losing its aligned state. As described above, the present invention has the remarkable effect that the case body 1 can be easily removed from the ribbon storage section 71 which has only a narrow space.

A portion of the filled endless ribbon 2 is spread over both openings 8a and 8b of the cartridge case 7. In addition, in FIG. 4, 91 and 92
are the drive roll and presser roll, respectively,
The endless ribbon 2 is fed in the direction of arrow C. Further, reference numeral 10 denotes a leaf spring, which prevents the endless ribbon 2 fed from the ribbon storage section 71 from sagging in the printing section (not shown).

The case body 1 and the insole 3 are made of, for example, polyethylene, polypropylene, nylon,
It is made of plastic molded products such as ABS resin, paper, wood, etc. with a thickness of about 0.2 to 5 mm.
The plastic molded article is usually black or dark colored, but transparent or translucent ones can also be used. The folded part 4 formed on the bottom surface 11 of the case body 1 can be formed by folding back any part of the bottom surface 11 (for example, approximately the center or near the end of the bottom surface 11), and this part It functions as a hinge for opening one side 1a of the main body.

In addition, the insole 3 is the other side 1b of the case body and the bottom surface 11
Alternatively, the insole 3 may be interposed only on one side 1a of the case body.

As mentioned above, since the sub-cassette of the present invention allows the endless ribbon 2 to be easily filled into the cartridge case 7 with rough operations, it is almost impossible to disturb the alignment of the ink ribbons.
Its practical value is extremely great.
