Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette lid for a video tape recorder, and more particularly to a cassette lid that allows a compact cassette mounting space.

Generally, video cassettes have a tape drawer opening that is covered with a cassette lid to prevent the tape from being exposed outside the case when not in use.When the video cassette is installed in a video tape recorder, the cassette lid opens upwards and the tape is removed. It is structured so that it can be pulled out. FIG. 1A shows a video cassette 2 mounted on a general video tape recorder 1, with a tape 3 mounted along a predetermined running path. At this time, the cassette lid 2a of the video cassette 2 is attached to the recorder 1 as shown in FIG. 1B.
The lid opens above a tape drawer opening 2c formed on the front surface of the cassette case 2b in contact with a pin 1a implanted therein.

Here, when the cassette is installed, the video cassette 2 is
The upper surface of the video tape recorder 1 is inserted into a cassette holder 4 covered by a cassette lid 4a, and the video tape recorder 1 and the cassette holder 4 are mounted at a predetermined mounting position. However, the cassette lid 4a is conventional, and therefore a space 5 is required between the lower surface of the cassette lid 4a and the upper surface of the cassette case 2b to allow the cassette lid 2a to be opened. For this reason,
In the video tape recorder 1 using the conventional cassette lid 4a, the volume of the space required for mounting the cassette (cassette mounting space) in the entire recorder is large, and the space 5 is occupied by a spring 6 for holding the cassette. Since it is necessary to install the video tape recorder 1 in a compact size, it cannot be used as a space for arranging circuit components, etc., and therefore, it is difficult to make the video tape recorder 1 compact.

The present invention eliminates the above-mentioned drawbacks of the conventional video cassette, and a video cassette with a tape drawer opening in the cassette case covered with a cassette lid is installed, and the cassette lid is opened upward in conjunction with the loading operation. A main lid that covers a cassette mounting space and a sub-lid that is opened by the cassette lid and allows the cassette lid to be opened when the cassette lid is opened. It is an object of the present invention to provide a cassette lid for a video tape recorder, which has a structure in which the cassette mounting space can be made thinner and the entire video tape recorder can be made more compact.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. FIGS. 2 and 3 respectively show a vertical sectional side view of a main part of an embodiment of a video tape recorder to which the cassette lid of the present invention is applied, and an exploded perspective view of an embodiment of the cassette lid.

In Figures 2 and 3, the cassette lid 1 according to the present invention
1 consists of a main lid 11a which can be opened and closed on the upper surface of the cassette holder 4, and a sub-lid 11b which is separately provided on the main lid 11a and can be opened and closed.

In the case of this embodiment, the sub-lid 11b is pivotally supported by a common pivot pin 12 with the main lid 11a, as shown in FIG. 4, and forms approximately the same plane as the main lid 11a when the cassette 2 is not attached. A torsion spring 13 is fitted onto the pivot pin 12 so as to
It is energized clockwise in FIG. 3 by.

To install the video cassette 2, open the cassette lid 11 and insert the cassette 2 into the holder 4. Next, the cassette lid 11 is closed and the holder 4 is lowered to a predetermined position by pushing the cassette lid 11 from above. As a result, the cassette 2 held in the holder 4 is placed in the installed state, but when the cassette lid 11 is pushed from above, the cassette lid 2a comes into contact with the pin 1a and is opened upward.

At this time, the cassette lid 2a is opened by pushing up the sub-lid 11b from below at the same time as the opening operation. Therefore, when the sub-lid 11b is opened, the main lid 11a approaches the cassette case 2b while the cassette lid 2a closes.
The lid can be opened easily.

The cassette lid 11 having the above configuration as described above
The sub-lid 11b is provided to be opened by the cassette lid 2a, and is configured so as not to interfere with the opening operation of the cassette lid 2a, thereby eliminating the gap between the upper surface of the case 2b and the lower surface of the lid 4a, which was previously required. The space 5 for opening the cassette lid is no longer required, and as a result, the cassette mounting space, which is required only for mounting the cassette 2, is made thinner to the minimum necessary thickness, although it is slightly larger than the thickness of the cassette 2. be able to.

Therefore, for example, if the volume of the cassette holder 4 is the same as that of a conventional video tape recorder, the volume occupied by the cassette holder 4 can be reduced by making the cassette mounting space thinner, so that it can be incorporated into the video tape recorder accordingly. This allows you to freely layout circuit components, etc. On the other hand, since the cassette holder 4 can be made smaller, the video tape recorder can be made thinner.

In the above embodiment, the cassette lid 11 is constructed so that the upper surface of the cassette holder 4 is covered with the main lid 11a which can be opened and closed, but the main lid 11a is fixed to the cassette holder 4.
A configuration may be adopted in which only the sub-lid 11b is opened by the cassette lid 2a. In this case, the video cassette 2 is inserted through the front opening of the cassette holder 4 and housed within the holder 4.

As explained above, according to the cassette lid of the video tape recorder of the present invention, when the cassette lid is opened in connection with the video cassette loading operation, the cassette lid opens the cassette lid and allows the lid to be opened. Since the main lid is configured with a sub-lid, it is possible to fit the main lid closely to the cassette case without considering the space for opening the cassette lid, thereby saving the cassette mounting space required only for mounting the video cassette. It is possible to make the video tape recorder thinner, to freely lay out circuit components, etc., and to make the entire video tape recorder thinner.
