Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sub-cassette for replenishing endless ink ribbon to a ribbon cassette for printing in a printing device. More specifically, there is a case formed by a surrounding side plate and a top plate with an open bottom, an endless ink ribbon (hereinafter simply referred to as ribbon) stored in the case in a folded state, and a case formed by the top plate and the ribbon. The present invention relates to a sub-cassette consisting of a presser plate disposed in between.

Conventionally, this type of sub-cassette is known as shown in Japanese Utility Model Application No. 57-90856.

However, in this case, the case 51 and the press plate 52 are integrally connected at one end, so
After the case 51 is stored with the bottom surface facing the bottom of the ribbon chamber 54 of the ribbon cassette 53, when the case 51 of this sub-cassette is swung around the connection point with the presser plate 52, the presser plate 52 moves toward the bottom of the ribbon chamber 54 of the ribbon cassette 53.
The central part receives a force that lifts it upward as a reaction force of the swing (see Fig. 5). For this,
The vicinity of the center of the ribbon A stored in this sub-cassette rises from the ribbon chamber 54, and the presser plate 5
When lifting 2 next, ribbon A is placed in the ribbon chamber 54.
There is a risk that it may fly out.

The object of the present invention is to eliminate the drawbacks of such a subcassette in which a case and a presser plate are connected.

In order to achieve this object, the subcassette of the present invention includes a case formed by a peripheral side plate and a top plate and having an open bottom, an endless ink ribbon stored in the case in a folded state, and the above-mentioned endless ink ribbon. In a sub-cassette comprising a presser plate disposed between a top plate and the endless ink ribbon, the presser plate and the case are connected to each other by a pivot shaft-like body whose axis is directed laterally at one end of the case. The case is pivotally connected to each other and is provided with means for rotating the case about the pivot shaft with respect to the holding plate.

In the sub-cassette of the present invention, since the case swings smoothly relative to the presser plate, there is no situation where the center of the presser plate lifts upward.
The ribbon of the sub-cassette can be reliably and easily fed into the storage chamber of the ribbon cassette.

Next, the subcassette of the present invention will be explained using the drawings.

1-2, a first embodiment of the subcassette of the present invention is shown. Reference numeral 1 denotes a case, in which left and right side plates 11 and 12 extend downward from the left and right sides of the top plate 10, and a first end side plate 15 having an opening 14 for inserting the tongue piece 13 extends at one end. The other end and the bottom part are open. Reference numeral 2 denotes a presser plate, and the tongue piece 13 is integrally extended from one end of the main body 16, and a second end side plate 17 is extended downward from the other end of the main body 16. Further, on both left and right sides near the free end of this side plate 17, mutually concentric pivot shafts 18 and 19 are provided.
are provided protrudingly, and these pivot shafts 18, 19 are rotatably inserted into pivot holes in the left and right side plates 11, 12 near the open end of the case 1. In this way, the tongue piece 13 can be held down with the fingers of one hand and the case 1 can be held and rotated with the other hand. A is a folded and stored endless ribbon.

In FIG. 3, a second embodiment of the invention is shown. In the second embodiment, the pivot shafts 18, 1
9 is the main body 16 and second end side plate 17 of the presser plate 2.
Pivot holes are formed in the left and right side plates 11 and 12 near the top plate 10 to project from the left and right sides of the continuous portion with or near the top plate 10, and through which the pivot shafts 18 and 19 are inserted. The rest is the same as the first embodiment. By doing this, even when the case 1 is rotated upward, the end of the case 1 near the pivot axis will not protrude beyond the main body 16 of the holding plate, thereby reducing the size of the sub-cassette. The ribbon storage chamber can be made large enough to approximate the size of the ribbon storage chamber of the ribbon cassette.

In Fig. 4, the third subcassette of the present invention is shown.
An example is shown. In the third embodiment, a hemispherical protrusion 18 is used instead of the pivot shafts 18 and 19.
a, 19a are provided on the second end side plate 17, and recesses into which the protrusions 18a, 19a are fitted are provided on the left and right side plates 11, 12 instead of the pivot holes. The rest is the same as the first or second embodiment.

In the above-mentioned embodiments, it is also within the technical scope of the present invention that the configuration is modified by one or more of the following combinations.

(1) As a means for rotation, a finger insertion hole is formed in the top plate 10 instead of the tongue piece 13.

(2) The pivot shafts 18, 19 or the protrusions 18a, 1
The formation locations of 9a and the corresponding pivot hole or recess are interchanged.

(3) Holding plate main body 16, top plate 10, and side plates 11, 1
Any or all of 2, 17, and 15 are formed in a net shape or a lattice shape.

(4) Either the case 1 or the holding plate 2 must be made of plastic or paper.

(5) A pivot shaft-like body should be provided approximately at the center of the height of the side plate 17.
