Abstract

(57) [Summary] [Purpose] To provide an ink ribbon cassette that can reduce the cost by downsizing the packaging box and is less likely to be damaged when subjected to impact such as dropping. [Structure] An ink ribbon cassette in which a rotary knob 2 for tensioning a relaxed ink ribbon 1 is removably protruded from a cassette case 3.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an ink ribbon cassette installed in a printer or the like.

0002

[Conventional technology]

Conventionally, an endless cloth ink ribbon and a method for transporting the ink ribbon were used. Ink ribbon cassette with a driving roller (or gear) and a driven roller (or gear) There is a This type of ink ribbon cassette has a drive roller (or gear). You can tighten the loose ink ribbon by manually rotating the The knob for rotating the drive roller (or gear) is attached to the cassette case. It was protruding from the outside of the ground. Other than this knob, there are no other protruding parts on the cassette case. There are no large parts, so the total height is approximately doubled due to only the knobs. This had the disadvantage that the packaging box was also large and the cost was high. Also, if you fall, the Another problem was that it was easily damaged when a shock was applied to it.

0003

[Problem that the idea aims to solve]

This invention enables the packaging box to be made smaller, reducing costs, and prevents it from falling. It is not easy to break when subjected to impact, and of course, if the ink ribbon becomes loose, it can be tightened. The purpose of the present invention is to provide an ink ribbon cassette that can be used for printing.

0004

[Means to solve the problem]

In order to achieve the above object, the ink ribbon cassette of the present invention has a relaxed ink ribbon. The rotary knob 2 for tensioning the clip ribbon 1 can be detached from the outside of the cassette case 3. It is constructed by protruding from the

[0005]

[Effect]

The packaging box can be made smaller by storing it in the packaging box with the rotary knob 2 removed. can be converted into Also, if you carry it with the rotary knob 2 removed, it will not work even if you drop it. Since the rotary knob 2 is not subjected to impact, it is less likely to be damaged. ink ribbon 1 Of course, when the ink ribbon becomes loose, attach and rotate the rotary knob 2 to remove the ink ribbon. It can make N1 nervous.

【Example】

Hereinafter, embodiments will be described in detail based on the drawings. There is no memory inside the cassette case 3. A running path of the ink ribbon 1 made of cloth without a cloth is configured, and an ink ribbon is placed along the way. A ribbon storage chamber 4 is provided in which the ribbon 1 is stored in a folded state. A driving roller 5 and a driven roller 6 are placed in front of the ink ribbon 1. The ribbon is sandwiched between the driving roller 5 and the driven roller 6 and drawn into the ribbon storage chamber 4. ing. The core shaft 7 of the drive roller 5 has a fitting hole 8 for the printer's drive shaft on the lower surface side. The drive roller 5 is then rotated by the printer. The driven roller 6 is a driving roller. It can freely move back and forth by the required amount with respect to the roller 5, and is pressed by a spring 9. It is in contact with the drive roller 5 while sandwiching the ink ribbon 1 therebetween. Core shaft 7 of drive roller 5 A mounting hole 11 is provided on the top surface side, into which the mounting shaft 10 of the rotary knob 2 can be inserted and removed. The mounting shaft 10 and the mounting hole 11 are engaged with each other by elastic deformation, respectively. A releasable protrusion 12 and a recess 13 are provided. Rotary knob 2 is for loosened ink. When tensioning the ribbon 1, the ribbon 1 is fitted onto the core shaft 7 of the drive roller 5. Otherwise, it should be removed. Therefore, when storing it in a packaging box, please remove it. Therefore, the packaging box can be made smaller by reducing the thickness by the amount of the rotary knob 2. When rotary knob 2 is attached to drive roller 5 and rotated manually A rotary wheel is provided so that the drive roller 5 also rotates integrally to transport the ink ribbon 1. The mounting shaft 10 of the roller 2 and the mounting hole 11 in the core shaft 7 of the drive roller 5 rotate respectively. It is shaped so that it can be stopped.

[0007]

[Effect of the idea]

The present invention is as described above, and since the rotary knob 2 is made detachable, the loosened The link ribbon 1 can be removed except when tensioning, so it can be stored in the packaging box. You can make the packaging box smaller by removing it when storing it, and it also makes it easier to carry it. It is said that if you remove it and put it in place, you can avoid major damage if you accidentally drop it. effective.
