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 surface 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, pinch the rear left and right sides of the sliding lid in the open state to finish the removal, and the bottom opening opens. It turns out that there is a problem that it may be taken out as it is.

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 configured so that the sliding lid can be opened by inserting the tape cassette, and the sliding lid can be securely closed when the tape cassette is taken out. Of the tape cassette insertion guide portion is provided with a sliding lid braking member that elastically projects on the lower surface of the tape cassette insertion guiding portion and is in sliding contact with the lower surface of the sliding lid that is in the open state.

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 after the insertion is completed, and when the tape cassette is taken out, the same first operation as when the insertion is completed is performed. If the tape cassette body protruding from the cassette holder is pinched and taken out, the sliding lid will be removed by frictional force or engagement between the lower surface of the sliding lid and the sliding lid braking member. Stays in the cassette holder until it is completely closed,
It will be taken out after it is completely closed.

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

FIG. 4 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. 5 is a side view thereof, and 3 is a sliding lid that opens and closes the bottom opening and is always spring-biased in the closing direction, but it is locked in both open and closed positions by the lock mechanism. Show. 6 is a front view thereof, 4 is a notch provided in the rotary lid 2, and the front end portion of the sliding lid 3 is seen in the inside thereof. 5 is a notch also provided in the rotary lid 2 for sliding. The unlocking portions at both open and closed positions of the lid 3 communicate with a groove (see FIG. 8). FIG. 7 is a side view showing a state where the sliding lid 3 is locked at the open position, and FIG. 8 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. 9 is a bottom view showing the lid closed state.

FIG. 1 is a side view of an essential part showing a position where a tape cassette is inserted / removed, that is, a first position of a cassette holder in a first embodiment of the present invention, and a tape cassette is completely inserted. 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. Reference numeral 2 is a rotary lid, 3 is a sliding lid that is opened, 6 is a cassette holder, 7 is a cassette holder bottom plate, 8 is a sliding lid opening abutment portion in which a part of the cassette holder bottom plate 7 is bent and raised, and 9 is It is a sliding lid braking member provided so as to project above the lower surface of the insertion guide of the cassette holder 6, and is made of a soft elastic material such as rubber or vinyl chloride, and elastic so as to be a relief direction with respect to the cassette insertion direction. Supported by the public. 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. Reference numeral 11 is a rotation shaft of a cassette holder, 12 is a cassette holder bearing, 13 is a chassis, and 14 is a reel stand for engaging and driving a tape hub (not shown) in a tape cassette to wind or supply the tape. , 15 are contact pins for opening the rotary lid. FIG. 2 is a partial side sectional view showing the main part thereof.

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, even if the fingertip is applied to the side portion of the sliding lid 3, the course opposite to that at the time of insertion is followed. That is, after the sliding lid 3 is unlocked to the open position, the sliding lid 3 stays in the cassette holder by the returning force in the closing direction and the large braking force acting in the biting direction of the sliding lid braking member. It is taken out together with the cassette body after it is closed.

As described above, according to the present embodiment, a tape cassette having a sliding lid that opens and closes by sliding the bottom opening and is locked at both open and close positions is used. It is possible to realize a cassette holder that can be opened and closed surely by braking by the sliding lid braking member of the sliding lid upon insertion and removal with an extremely simple configuration.

Since the sliding lid braking member is elastically supported in a direction so that it is in the escape direction with respect to the insertion direction of the tape cassette and with the intrusion direction in the removal direction, the tape cassette is supported. When inserting, it can be inserted smoothly without any resistance.

FIG. 3 is a side view of the cassette holder according to the second embodiment of the present invention, showing a state where the tape cassette has been inserted.

In the figure, 16 is a sliding lid braking member and 17 is a sliding lid braking member.
At the other end of 16 the cassette holder 6 contacts the chassis 13 or a member provided on the chassis while moving the cassette holder 6 from the first position to the second position, and the sliding lid braking member 16 is rotated counterclockwise. Then, the sliding lid braking member 16 protruding into the cassette insertion guide path of the cassette holder 6 is moved backward to be removed. 18
Is a spring for urging the sliding braking member 16 clockwise, 19
Is a support shaft that rotatably supports the sliding lid braking member 16.

With this configuration, the force of the sliding lid braking member does not act on the tape cassette at the playing position, so that the tape cassette can be properly positioned.

In this embodiment, a high-friction material is attached to the braking portion of the sliding lid braking member, and it is controlled by the tip shape, elastic force, surface roughness or unevenness of the lower surface of the sliding lid 3, and concave portions for engagement. The magnitude of power can be arbitrarily selected.

Further, the sliding lid braking member is not limited to one provided on the lower surface except for the cassette insertion guide path, and one shown in FIG. 1 may be provided on both left and right sides to correspond to the side surface of the sliding lid 3. It's good.

As described above, the present invention uses the tape cassette having the sliding lid that opens and closes the bottom opening by sliding, and the insertion guide means for inserting and guiding the tape cassette in the main plane direction and the insertion guide means. Since a sliding lid braking member that elastically protrudes into the guide path and is in sliding contact with the lower surface of the sliding lid is provided, the braking force acts on the sliding lid when taking it out, and the sliding lid is securely closed before taking it out. be able to.
