Description

[Detailed Description of the Invention] The present invention relates to an adapter for a small tape cassette, and particularly provides an adapter for a small tape cassette that is configured so that the front lid of the small tape cassette is automatically opened during the process of storing the small tape cassette. It's about doing.

The present applicant has previously proposed a tape cassette that is smaller than the standard tape cassette, and an adapter for use in attaching this small tape cassette to a standard recording/reproducing device. This adapter does not have a mechanism to open the front lid of the small tape cassette that is stored in it, and the small tape cassette can be opened by opening the lid by pushing it forward with the tip of the tape. will be stored in. When storing a small tape cassette, it must be handled with the lid open, which poses a problem in that the magnetic tape may be damaged during storage, which is not desirable in terms of protecting the tape.

The present invention solves the above problems, and one embodiment thereof will be described below with reference to the drawings.

As shown in FIGS. 1A and 1B, a small tape cassette adapter 1 has substantially the same external dimensions as a standard tape cassette, and has a small tape cassette storage section 2 inside. This adapter 1 stores a small tape cassette 3, which is smaller than a standard tape cassette, in a storage part 2, closes a top cover 5 to cover the small tape cassette 3, and further rotates an operation knob 6. Tape loading is performed within the adapter to form a predetermined tape path, and the tape is inserted into the cassette housing of a standard recording/reproducing device and installed in the device.

As shown in FIGS. 2A and 2B, the small cassette 3 includes a cassette housing 10 containing a magnetic tape, and
It consists of a lid 11 provided on the front side and normally closed to protect the magnetic tape inside. This lid 11 is inserted between the closed lid position shown by the solid line in FIG. 2B and the horizontal opened lid position shown by the two-dot chain line in
2, the U-shaped leaf spring 13 and the pressing rod 1
4 and are clicked into each position.

In Figures 1A and B, 20 is a folded piece for opening the lid;
A part of the base member 21, which is screwed at a height near the top plate of the adapter 1 and supports the operating knob 6, gear mechanism (not shown), etc., is bent upward. This bent piece 20 is located near the right end of the opening 22 of the adapter 1, and receives the lower edge 11a of the lid 11 of the small tape cassette 3 to be stored.
Further, the upper surface 20a of this bent piece 20 is a smooth slope that slopes downward toward the front of the adapter 1. Further, the loading arm is disposed on the inner bottom plate side of the adapter 1, and the bending piece 20 is located at a position where it does not interfere with rotation of the loading arm.

Now, insert the small tape cassette 3 into the adapter 1.
The operation when storing the small tape cassette 3 will be explained with reference to FIG.
As shown in FIG. 3, the top cover 5 is pushed down and stored in the open storage section 2. The small tape cassette 3 is positioned and stored by fitting the left and right grooves 10a, 10b of the cassette housing 10 into the corresponding guide protrusions 2a, 2b of the storage section 2.

Here, unlike the conventional case, the small tape cassette 3 is handled with the lid 11 closed and pushed down in the direction of the arrow X, as shown by the dashed line in FIG. stored inside. Lid 1
1 has its lower edge 11a in contact with the folded piece 12, and is guided by this inclined surface 12a and is pried open in the opening direction shown by arrow A, as shown by the two-dot chain line in the same figure, as the storage operation progresses. At the same time, it rotates in the direction of opening the lid. When the cassette case 10 is completely stored in the storage section 2 as shown by the solid line in the figure, the lid 11
The lid is rotated in a click-like manner to the horizontal position as shown by the solid line, and the lid is opened. That is, the small tape cassette 3 is stored in the adapter 1 with the lid 11 closed, and the lid 11 is automatically opened during the storage operation. Therefore, the small tape cassette 3 is stored in the adapter 1 without damaging the internal magnetic tape during the storage operation.

In addition, when the small tape cassette 3 is stored in the adapter 1, the bent piece 20 is inserted into the open lid 1.
Even if the lid 11 is pushed down to close it, the back surface 11b will hit the bending piece 20 and the rotation of the closed lid will be restricted, and the lid 11 will be closed. The lid is kept open. Therefore, even if the lid 11 is pressed by mistake, the lid will not close, and furthermore, the adapter can be applied without any problem to a front loading type recording/reproducing device in which the lid 11 is pressed by a roller.

As described above, according to the small tape cassette adapter of the present invention, since the opening part is formed as a part of the base member, the structure can be simplified compared to a structure in which the opening part is provided separately. Further, since the base member is provided near the top plate of the adapter, the opening portion formed on the base member can be placed at a location where it does not interfere with the tape loading operation within the adapter. Further, a small tape cassette can be stored in the adapter with the lid closed, which is convenient for protecting the tape and has good operability. In addition, even if you accidentally push down the open lid inside the adapter, the lid will remain open without closing.Furthermore, the front-loading type allows pressing force to be applied to the lid while the adapter is being installed. It has the advantage that it can be applied to recording and reproducing devices without any problems.

Claims (1)

[Scope of claim for utility model registration] An adapter for a small tape cassette used when a tape cassette smaller than a standard tape cassette is attached to a recording/playback device for standard tape cassettes, the height of the adapter near the top plate. During the process of storing the small tape cassette in the adapter, a portion of the base member that is fixed in position and supports a gear mechanism, etc., guides the lower edge of the front lid of the small tape cassette and attaches it to the base member. This adapter for a small tape cassette is configured to form an opening part that locks the back side of the opened lid when the lid is pried open and the storage of the small tape cassette is completed.
