Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette holder of a cassette recorder that uses a tape cassette with a lid for audio and the like.

2. Description of the Related Art In recent years, cassette holders have been implemented in various forms in video cassette recorders, audio cassette recorders, and the like.

Recently, a tape cassette with a lid has been proposed as a cassette for digital audio.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, the newly proposed tape cassette has a rotary lid that opens and closes the front opening, and a slide that opens and closes the bottom opening that also has an opening on the bottom that is continuous with the front opening. If you use a cassette holder like a conventional tape cassette (compact cassette) that has a moving lid, the rear side of the sliding lid in the open state will be pinched and taken out, leaving the bottom opening open. It turned out that there was a problem that it could be taken out.

In view of the above problems, the present invention provides a cassette holder that can be used in almost the same manner as a conventional tape cassette, even if such a tape cassette with a sliding lid is used.

Means for Solving the Problems In order to solve the above-mentioned problems, the cassette holder of the present invention is designed so that the sliding lid can be opened by inserting the tape cassette, and the sliding lid can be reliably closed when the tape cassette is taken out. Of the tape cassette insertion guide portion, a sliding lid opening contact portion and a high friction member provided on the guide surface facing the lower surface of the opened sliding lid are provided.

With the above-described structure, the present invention performs the performance at the second position where the tape cassette is moved together with the cassette holder in the direction substantially perpendicular to the insertion direction with the sliding lid opened after the insertion is completed, and the tape cassette is taken out. Sometimes, after returning to the same first position as when the insertion was completed, if the rear portion of the tape cassette body protruding from the cassette holder is pinched and taken out, sliding is caused by the frictional force between the lower surface of the sliding lid and the high friction member. The lid will remain in the cassette holder until it is fully closed and will be fully closed before removal.

Example A cassette holder according to an example of the present invention will be described below with reference to the drawings.

FIG. 3 is a top view of the proposed tape cassette with a lid, in which 1 is a cassette body and 2 is a rotating lid for opening and closing the front opening, which is always biased in the closing direction by a spring. FIG. 4 is a side view thereof, and 3 is a sliding lid for opening and closing the bottom opening, which is always biased by a spring in the closing direction but is locked in both open and closed positions by a locking mechanism. The figure shows the closed position. FIG. 5 is a front view thereof, 4 is a notch provided in the rotary lid 2, and the front end of the sliding lid 3 is seen inward, and 5 is a notch also provided in the rotary lid 2. The unlocking portions at both open and closed positions of the lid 3 communicate with a groove (not shown). FIG. 6 is a side view showing a state where the sliding lid 3 is locked at the open position, and FIG. 7 is a side view showing a state where the rotating lid 2 is opened. As can be seen from the figure, the rotary lid 2 can be opened only after the sliding lid 3 is completely opened.

FIG. 1 is a side view of essential parts showing a position of the tape holder in the cassette holder in the first embodiment of the present invention, which is the tape cassette inserting / removing position, that is, the first position. In FIG. 1, reference numeral 1 denotes a cassette body in a state in which the cassette body is completely inserted into the cassette holder. 2 is a rotating lid, 3 is an open sliding lid, 6 is a cassette holder, 7
Is a bottom plate of the cassette holder, 8 is an abutting part for opening the sliding lid in which a part of the bottom plate of the cassette holder 7 is bent, and 9 is a high friction member provided on the lower surface of the insertion guide of the cassette holder 6, such as rubber or vinyl chloride. The sheet-shaped or band-shaped body. Reference numeral 10 urges the tape cassette inserted by a cassette pushing spring provided on the upper inner wall of the cassette holder 6 downward. 11 is a rotation support shaft of the cassette holder, 12 is a cassette holder bearing,
Reference numeral 13 is a chassis, 14 is a reel base for engaging and driving a tape hub (not shown) in the tape cassette, and winding or feeding the tape, and 15 is a contact pin for opening the rotary lid.

With this structure, when the tape cassette 1 is inserted, the lock of the sliding lid 3 to the closed position is released (the mechanism is not shown), and then the sliding lid 3 is slid. The front end of the lid 3 comes into contact with the lid 3 to start opening, and when the insertion is completed, the sliding lid 3 completes opening and is locked in the open position (the mechanism is not shown). FIG. 1 shows this state. When the cassette holder 6 is rotated clockwise from this state (first position) and brought to a predetermined performance position (second position), the rotating lid 2 contacts the contact pin 15 in the middle thereof. Contacted and released. When taking out the tape cassette after use, when the cassette holder 6 is brought from the second position to the first position (FIG. 1), the rotating lid 2 which is always biased in the closing direction is closed. The state shown in FIG. 1 is obtained.

If the tape cassette 1 is taken out from this state, the course opposite to that at the time of insertion can be followed even if the fingertip is applied to the side portion of the sliding lid 3. That is, after the sliding lid 3 is unlocked to the open position, the sliding lid 3 is stopped in the cassette holder by the restoring force and frictional force in the closing direction of the sliding lid 3 and completely closed before being taken out together with the cassette body.

As described above, according to the present embodiment, the tape cassette having the rotating lid that opens and closes the front opening and the sliding lid that opens and closes the bottom opening and is locked at both open and close positions is used. It is possible to realize a cassette holder which can be opened and closed surely by the frictional force between the sliding lid and the high friction member by inserting / removing the tape cassette in / from the main plane direction with a very simple structure.

FIG. 2 is a partial side view showing the main part of the cassette holder.

In the embodiment, the surface of the high-friction member is formed as a flat surface, but the fine uneven surface area may be a serrated surface or the like to increase the frictional force.

As described above, according to the present invention, the insertion guide means for inserting and guiding the tape cassette in the main plane direction thereof, and the sliding lid opening abutment portion for opening the sliding lid during the insertion of the tape cassette are inserted. The tape cassette pressing means for pressing and urging the tape cassette downward and the high friction member provided on the guide surface facing the lower surface of the opened sliding lid have no change on the tape cassette side. It is possible to open and close the sliding lid with certainty by inserting and removing the cassette holder without adding.
