Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a cassette holder device for a tape recorder, and in particular, to a cassette holder device that allows the cassette holder to be mounted reliably and easily.

B. Summary of the invention The present invention provides a cassette holder with a pair of rotating arms, and a supporting pin provided on the rotating arms is pivotally supported by a pivot provided on a cabinet constituting the main body of the tape recorder. In addition to attaching the holder, the pivot portion of the support pin is supported by the mechanism main body to prevent it from coming off the pivot portion.

C. Conventional technology Conventionally, the cassette holder of a tape recorder was
It is installed as shown in Figure 4.

What is shown in FIG. 4 is a pair of tape reel drive devices 1, 1 for rotating the tape reel of a tape cassette, a capstan 2 and a pinch roller 3 for running the magnetic tape at a constant speed, and an information signal for the magnetic tape. A cassette holder 7 is attached via holder support plates 6, 6 attached to both sides of a mechanism main body 5 in which a magnetic head 4 for recording and reproducing is incorporated.

That is, the cassette holder 7 into which the tape cassette is inserted and mounted has the pair of holder support plates 6,
Support pins 9, 9 protruding from the opposing inner surfaces of 6
These support pins 9, 9 are used as fulcrums to be rotatably attached. In addition, the cassette holder 7 has a support shaft 1 installed at the lower end midway on both sides.
By engaging the guide rollers 11, 11 attached to the holder support plates 6, 6 with the guide holes 12, 12 for regulating the rotation range, the guide rollers 11, 11 attached to the guide rollers 11, 10 are guided by the guide holes 12, 12. It is rotatable between a tape cassette loading position and a tape cassette loading/unloading position.

D Problems to be Solved by the Invention By the way, the tape recorder cassette holder has the function of guiding the loading and unloading of the tape cassette installed in the tape recorder. It is installed so that it can be rotated both inside and out. Therefore, in order to ensure smooth rotational operation between the inside and outside of the cabinet, the cassette holder must be installed in the opening of the cabinet at an accurate position.

However, in the above-described cassette holder device, the cassette holder 7 is attached via the holder support plates 6, 6, which are attached to the mechanism main body 5 independently of the cabinet. Not only is it difficult to align the mechanism body 5 with the mechanical body 5, but it is also necessary to attach the holder support plates 6, 6 and the cassette holder 7 after assembling the mechanism body 5, which complicates the assembly work of the mechanism body 5. Furthermore, an independent part for attaching the cassette holder 7 is required, which inevitably increases the number of parts.

Therefore, the present invention solves the problems caused by attaching the cassette holder to the mechanism side, makes it easy to position the cassette holder with respect to the cabinet, maintains a secure attachment state, and enables easy installation. This invention was proposed for the purpose of providing a cassette holder device for a tape recorder.

E. Means for Solving the Problems In order to solve the above-mentioned problems and achieve the above-mentioned objectives, the present invention provides two tape cassettes on both sides of the proximal end of the cassette holder body into which the tape cassette is attached. A cassette holder having a support pin protruding from the outer surface of the rotating arm portion, and a pivot part on which the support pin provided on the cabinet is pivoted are provided, and the support pin is pivoted to the pivot part to hold the cassette. The holder is rotatably attached to the cabinet, and at least a part of the mechanism main body disposed in the cabinet is exposed between the rotating arms, so that the mechanism main body can rotate the support pin from the pivot point. This is to prevent it from falling out.

F Function The present invention bends the rotating arms provided on both sides of the proximal end of the cassette holder main body in a direction toward each other, and connects support pins protruding from these rotating arms to a pivot point provided on the cabinet. The cassette holder is rotatably attached to the cabinet by being pivoted to the branch, and at least a part of the mechanism main body disposed in the cabinet is made to face the pivot part of the support pin. This prevents the support pin from coming off.
