Description

The present invention belongs to the technical field of an ink ribbon cassette provided with an ink impregnating body for supplying ink to an ink ribbon, which is used by being attached to a printer.

As an ink ribbon cassette provided with an ink impregnated body, there is one described in Patent Document 1 shown in an exploded perspective view of FIG. The ink ribbon cassette 100 includes a case 200 and a cover 400. The cover 400 is provided with a hollow ink impregnated body storage portion (ink tank) 430 for storing an ink impregnated body (not shown) obtained by impregnating ink in a sponge, felt, or the like. A part (wick) W of the ink impregnated body protrudes from the inside of the portion 430.

The case 200 is formed in a shape for receiving a print head portion (not shown) of the printer, and is provided with a ribbon storage portion 220 for storing the endless ink ribbon R by folding it. Two ink ribbon feed rollers 240a and 240b are rotatably arranged near the entrance of the ribbon storage unit 220, and the ink ribbon R is sandwiched between the rollers 240a and 240b. In the assembled state, the ink ribbon cassette 100 has the ink impregnated body accommodating portion 430 of the cover 400 positioned above the ribbon accommodating portion 220 of the case 200, and the wick W protruding from the ink impregnated body on the side surface of one ink ribbon feed roller 240a. Are in contact. Therefore, when the roller 240a rotates, ink is transferred to the surface of the roller 240a by the wick W. In the following description, in order to distinguish between the two ink ribbon feed rollers, the ink ribbon feed roller 240a in contact with the wick W is referred to as an ink transfer roller as necessary. The ink transfer roller may be provided separately from the ink ribbon feed roller.

When the ink ribbon cassette 100 is attached to the print head portion of the printer, the drive shaft of the printer is engaged with the center of one of the ink ribbon feed rollers 240a (240b) so as to be able to transmit torque. When the drive shaft is rotated by driving the motor, the ink ribbon feed roller 240a (240b) engaged with the drive shaft is rotated. When the ink ribbon feed roller 240a (240b) is rotated, the other ink ribbon feed roller 240b (240a) is also rotated. As a result, the ink ribbon R in the ribbon storage unit 220 is pulled out from the outlet portion, and the print head portion of the printer After being printed, the ribbon is again fed into the ribbon storage unit 220, folded and stored. Note that either of the two ink ribbon feed rollers 240a and 240b may be engaged with the drive shaft of the printer, and can be appropriately changed depending on the configuration of the printer.

In this ink ribbon cassette 100, since the wick W protruding from the ink impregnated body in the ink impregnated body housing 430 is in contact with the side surface of the ink transfer roller 240a, the ink transfer is performed by the rotation of the two rollers 240a and 240b. The ink transferred to the roller 240a is automatically supplied to the ink ribbon R.

Next, FIG. 5 shows another conventional ink ribbon cassette 102 (described in Patent Document 2), FIG. 5 (a) is a partial top view with the cover removed, and FIG. 5 (b) is ink impregnation. It is a disassembled perspective view of a body storage member. As shown in FIG. 5A, the ink ribbon cassette 102 includes a case 202 and an ink impregnated body storage member 300 formed separately from the cover. The ink impregnated body storage member 300 is a ribbon storage portion of the case 202. It is disposed in a mounting portion 224 provided adjacent to 222. Since the ink ribbon cassette 102 is the same as that shown in FIG. 4 except for the configuration of the ink impregnated body storage member 300 and the cover 400 described below, the same reference numerals are given and description thereof is omitted.

An ink impregnated body 32 is accommodated in the case-shaped ink impregnated body accommodating member 300, and a part (wick) W of the ink impregnated body 32 protrudes to the outside (see FIG. 5B). In the assembled state, the wick W comes into contact with the ink transfer roller 240a. Further, a wedge-shaped cam 420 is provided on the surface of the cover that faces the ink impregnated body storage member 300 (see FIG. 5A).

The ink impregnated body storage member 300 is placed on a mounting portion 224 provided in the case 202 and covered with a cover. In this ink ribbon cassette 102, the mounting portion 224 is formed larger than the ink impregnated body accommodating member 300 so that the ink impregnated body accommodating member 300 can be easily arranged. However, if the cover is covered as described above, the ink impregnated body The storage member 300 is pressed by the wedge-shaped cam 420 and moved in a direction in which the wick W comes into contact with the ink transfer roller 240a.

In order to improve the printing life of the ink ribbon cassette, the ribbon storage unit and the ink impregnation unit storage member (ink impregnation unit storage unit) are arranged so that a longer ink ribbon and a larger ink impregnation unit can be stored. The volume must be increased. However, in the ink ribbon cassette 102 shown in FIG. 5, the ribbon storage unit 222 and the ink impregnated body storage unit 300 are arranged adjacent to each other in a case 202 having a fixed capacity. There is a problem that both of them cannot be made sufficiently large at the same time. Furthermore, according to the ink ribbon cassette 102 shown in FIG. 5, since the ink ribbon cassette itself has been miniaturized with the recent miniaturization of printers, the ribbon storage unit 222 and the attachment unit 224 for storing the ink impregnated body storage member 300 are used. It is difficult to increase the volume.

On the other hand, if the wick W is strongly pressed against the ink transfer roller 240a, the rotation of the ink transfer roller 240a is obstructed, causing the running failure of the ink ribbon R, and conversely the pressing force of the wick W is weak. If the ink transfer roller 240a and the ink ribbon R are not sufficiently supplied with ink, the characters will be missing or shaded during printing, so that the wick W has an appropriate amount on the side surface of the ink transfer roller 240a. It must be pressed by pressing force. However, in the ink ribbon cassette 100 of FIG. 4, since the ink impregnated body storage portion 430 is provided in the cover 400, it is difficult to confirm the position of the wick W from the outside when the cover 400 is put on the case 200, and the wick W is fixed to It is difficult to press the wick W against the ink transfer roller 240a with an appropriate pressing force. In addition, since the wick W is made of a material that is easily damaged, such as sponge or felt, in the ink ribbon cassette 100 of FIG. 4, when the wick W is attached, the wick W hits parts in the case 200 and is damaged or deformed. There is a risk that.

As described above, the ink ribbon cassette 100 shown in FIG. 4 can store the long ink ribbon R and the large ink impregnated body 32. However, the wick W is properly attached to the ink transfer roller 240a during assembly. The ink ribbon cassette 102 shown in FIG. 5 has a problem that the volumes of the ribbon storage unit 222 and the ink impregnated body storage unit 300 cannot be increased at the same time.

In order to solve such problems, Patent Document 3 proposes an ink ribbon cassette having the following three features shown in FIG.
A. In order to increase the area of the ribbon storage section and the ink impregnated body for the purpose of improving the printing life, the ribbon storage section and the ink impregnated body storage section 30 provided in the case 20 are provided in a two-story structure.
I. Since it is difficult to mount the wick W due to the two-story structure, the ink impregnated body storage member 30 is separated from the case cover, and the wick W is mounted from the side of the ink transfer roller 24a. Form. Specifically, the ink impregnated body storage member 30 with the wick mounted thereon is rotatably held in the case 20, and the wick W is moved by this rotation.
The ink transfer roller 24a mounted on the sleeve 20 can be pressed from the side. Further, in order to facilitate the incorporation of the ink impregnated body storage member 30 into the case 20, when the cover is closed with the ink impregnated body storage section 30 mounted, the ink impregnated body storage section 30 rotates. The wick W is in contact with the ink transfer roller 24a. In other words, the guide wall 42 of the cover 40 covering the ink impregnated body storage member 30 serves as a guide, and the ink impregnated body storage member 30 rotates.
C. In order to stabilize the pressing force of the wick W against the ink transfer roller 24a, the cover 40
The engaging piece 460 protruding from the surface presses the ink impregnated body storage member 30 to press the wick W against the ink transfer roller 24a.

No. 4-10067 JP-A-9-109522 JP 2001-219630 A

However, the ink ribbon cassette of Patent Document 3 has the following two problems in terms of stabilizing the pressing force of the wick W on the ink transfer roller 24a.
D. Since the wick W is pressed against the ink transfer roller 24a by the engagement piece 460 protruding from the cover 40, the pressing force closer to the cover 40 tends to increase, and the amount of ink transferred is reduced. There is a tendency that a deviation occurs in the ribbon width direction and a difference in print density occurs in the ribbon width direction. (So-called contact is likely to occur.)
E. Further, the rotation operation of the ink impregnated body storage member 30 by the cover guide wall 42 and the cover 4
Since the engagement operation of the engagement piece 460 protruding from 0 to the ink impregnated body housing member 30 interferes simultaneously and in parallel, the engagement piece 460 must be very short in order to avoid this, The contact per piece described in item D becomes prominent.

In view of the above, the present invention is an ink ribbon cassette that has a two-story structure that extends the life of an ink ribbon cassette without enlarging the area of the ink ribbon cassette. It is an object of the present invention to provide an ink ribbon cassette that can simultaneously prevent the occurrence of uneven print density due to a piece of a supply member.
