Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette force bar for a tape recorder.

Conventionally, in the case of a tape recorder cassette cover in which a tape magazine holder is integrally formed using a resin or the like, cassette force is required to integrally shape the cassette cover body 1 and tape magazine holder 2 as shown in Fig. 1. JL3 is formed on the surface of the bar body 1 after being cut out.

Therefore, it is customary to arrange a cassette force bar plate 4 as a decorative plate on the surface of the cassette force bar body 1.

However, with such a cassette force bar, if the tape magazine is inserted and removed many times, the tape magazine holder is made of plastic and may deteriorate due to wear and breakage due to sink marks, weld lines, galling, etc. Not only will it not function as a cassette force bar, but there is a risk that the tape recorder itself will become unusable.

Furthermore, the tape magazine holder cannot be easily repaired, so the entire cassette force bar must be replaced.

In addition, a cassette force bar uses a spring made of a metal plate such as phosphor bronze as the tape magazine holder, and the spring is welded to the cassette force bar body or fixed to a screw or the like. Since it is attached from the back side, there is a drawback that if the tape magazine holder is bent or broken, the cassette force bar must be removed from the tape recorder body and repaired.

In order to solve the drawbacks of the conventional cassette force bar, in this invention, the cassette force bar plate attached to the cassette force bar body is not only used as a decorative plate, but also a part of the plate is used to hold down the tape magazine. To provide a cassette force bar in which a cassette force bar plate can be easily inserted and removed.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4, but the same parts as in FIG. 1 are denoted by the same symbols to avoid redundant explanation.

The cassette cover plate 4 is made of a metal plate such as phosphor bronze or stainless steel, and one side of the plate facing the insertion position of the tape magazine 5 is bent into a substantially U-shape, and the tip of the bent portion is elastically attached to hold the tape magazine 5. A tape magazine holder 2 is provided in the shape shown in FIG.

Further, the bent slope portion is provided with a mounting hole 4a for easily attaching the plate to the cassette power bar body 1 attached to the tape recorder body with a screw 6.

In addition, the surface of the cassette force bar body 1 is provided with grooves 1a on three sides in which the cassette force bar plate 4 can be inserted and locked without using adhesive, making it easy to install the cassette force bar plate 4. It is possible to do so.

Therefore, in the cassette force bar of the present invention, the cassette force bar plate doubles as a tape magazine holder, as described above, and is structured so that it can be easily inserted into and removed from the cassette force bar body. Even if the cassette force bar breaks, there is no need to replace the entire cassette force bar or remove the cassette force bar from the tape recorder body to repair it, as in the case of conventional ones.You only need to replace the cassette force bar plate, and it is easy to remove and install. It can be done.

Furthermore, by operating the screw 6 from the front of the tape recorder, the tightening strength can be changed and the tape magazine pressing force can be easily changed, which is very effective.
