Description

[Detailed description of the invention] [Industrial application field] Endless ink ribbons are often used in typewriters and other printing devices. This ink ribbon can be loaded into a magazine in a printing device and used repeatedly, but when the ink becomes thin after a certain amount of use, it needs to be replaced with a new one. To replace the endless ink ribbon with a new one, remove the old one from the magazine of the printing device and transfer the new endless ink ribbon filled in the replenishment case into the magazine.

The present invention relates to the structure of a case that houses replenishment endless ink ribbons that are supplied to users for replacement.

[Conventional technology]

Conventionally, cases for storing endless ink ribbons for refilling have been dish-shaped with a peripheral wall of a height roughly equivalent to the width of the ink ribbon, and in order to be able to accommodate the endless ink ribbons, the case has been made into a dish-like shape with a peripheral wall having a height roughly equivalent to the width of the ink ribbon. It contained folded ink ribbons. There are two places on the peripheral wall of the case,
For example, by forming vertical slits in opposing positions and pulling out the starting and ending ends of the ink ribbon,
These were connected outside the vessel to form an endless configuration.

As described above, endless ink ribbon replenishment cases have been known that are dish-shaped and have slits at two locations.

To fill a conventional refill case with ink ribbon, prepare an ink ribbon of a certain size that has been folded back into a fan fold, transfer it into the case, and pull out the starting and ending ends through separate slits. It was connected outside to form an endless shape.

[Problem that the invention attempts to solve]

In conventional endless ink ribbon refill cases, in order to fill the ink ribbon into the case, it is necessary to prepare a fan-folded ink ribbon of a certain size, and then this ink ribbon is transferred to the refill case. The drawback was that it was time-consuming and the work was not necessarily easy.

In view of the drawbacks of the prior art described above, the present invention is designed to improve the structure of the refill case so that the ink ribbon can be directly filled into the refill case using a pair of delivery rollers. It is.

[Means for solving problems]

The case body 1 is shaped like a dish with a circumferential wall 2 having a height that can accommodate the ink ribbon 7 folded into a fan fold, and the ink ribbon can pass through two locations on the circumferential wall in the vertical direction. The provision of the slits 3 and 4 is the same as in the conventional one.

In the present invention, a notch 6 is provided in at least one of the vertical slits 3 and 4 in a horizontal direction that intersects with the slit 3. This notch 6 allows the ink ribbon 7 to pass through the vertical slit 3 and allow a part of the pair of feed rollers 5 and 5' to protrude into the case body 1. Make it as large as possible.

[Effect]

In order to fill the case body 1 with the ink ribbon, as shown in FIG. 6 into the case body 1. In this state, pull out the tip of the ink ribbon and let it come out a little from the other slit 4. Thereafter, when the feeding roller is driven to feed the ink ribbon 7 into the case body 1, the ink ribbons sent in one after another are packed into the fanfold while swinging from side to side inside the case body 1. After filling the ink ribbon with a certain size in this way, the base end of the ink ribbon is cut off while protruding from the slit 3, and the tip protruding from the slit 4 and the base end protruding from the slit 3 are separated. By making the connection outside the device and making it endless, filling of the replenishment case with the endless ink ribbon is completed as shown in FIG.

At this time, a notch 6 is provided in the slit 3 portion in the transverse direction intersecting this, but the notch 6
is large enough for a portion of the delivery roller to enter, and does not cut off the entire peripheral wall, so the function of this portion as a wall is not impaired.

[Example] Hereinafter, an example of the endless ink ribbon replenishment case of the present invention will be described based on the attached drawings.

As shown in FIG. 1, a dish-shaped case body 1 having a peripheral wall 2 having a height (approximately the width of the ink ribbon) capable of accommodating the ink ribbon 7 folded into a fanfold is directly opposed to the case body 1. At these positions, vertical slits 3 and 4 are provided by cutting out a part of the peripheral wall.

A notch 6 is provided in the lateral direction intersecting the slit 3 in one of the vertical slits 3 and 4 located at opposing positions. As shown in FIG. 2, this notch 6 corresponds to the shape of the delivery rollers 5, 5', and has a shape that allows a portion of the delivery rollers 5, 5' to enter into the case body 1. In the illustrated embodiment, the shape of the feed-out roller is such that both upper and lower ends of the ink ribbon are narrowed and the ink ribbon is fed out. A portion of the peripheral wall 2 is left at the upper end and in the middle where it was removed.

The notches 6 may be provided in both parts of the vertical slits 3 and 4 provided at two locations, but they will function satisfactorily if they are provided in at least one of them. One of the vertical slits 3 and 4 passes through when the ink ribbon is filled into the case body 1, and the ink ribbon swings left and right at that time.
Therefore, the width of the vertical slit 3 provided so that the notches 6 intersect is made wider than the width of the vertical slit 4 in which the notch 6 is not provided.

To transfer from the replenishment case filled with endless ink ribbon shown in FIG. 3 to the endless ink ribbon magazine 8 of the printing device, as shown in FIG. The ink ribbons are placed in the ink ribbon storage section 9 so as to face each other. In this state, pull out the part 7a of the endless ink ribbon protruding from the case body 1,
The magazine 8 is wound around the guide roller 10 and set in a state of use. After that, when only the case body 1 is removed, the fan-folded endless ink ribbon is left behind in the ink ribbon storage section 9 of the magazine 8, and loading is completed.

The overall shape of the case body 1 of the endless ink ribbon replenishment case according to the present invention can be made into any shape, mainly depending on the shape of the magazine 8 of the printing device, especially the shape of the ink ribbon storage section 9 of the magazine. Furthermore, the two vertical slits 3 and 4 provided in the case body do not necessarily have to be located directly opposite each other as in the illustrated embodiment, but may be located at positions where the ink ribbon can be easily drawn out depending on the structure of the magazine. .

[Effect of idea]

According to the endless ink ribbon replenishment case of the present invention, the ink ribbon is loaded with a part of the feed roller protruding into the case body from the vertical notch provided in the horizontal direction that intersects with the vertical slit. By sending out the ink ribbon, there is no need to transfer the ink ribbon in a fan-folded state in advance, and the ink ribbon can be directly filled into the case body in a fan-folded state by the delivery roller.

Even after the endless ink ribbon is filled, the notch does not cut out the entire peripheral wall, so the function of the case is not impaired, and there is no risk of the ink ribbon flying out from the notch.
