Abstract

PURPOSE:To prevent a such wrong handling state as the slide cover of a taken- out tape cassette is kept locked at an open position, by providing a protection cover which opens the slide cover with insertion of a tape cassette and simultaneously covers the side wall part of the opened slide cover. CONSTITUTION:When a tape cassette 1 is inserted, the lock to set a slide cover 3 at a closed position is released. Then the front end part of the cover 3 abuts on a contact part 8. Thus an opening action of the cover 3 is started. The opening action of the cover 3 is over when the insertion of the cassette 1 is through. The cover 3 is locked at its open position. Under such conditions, a cassette holder 6 is turned clockwise and set at a prescribed playing position. Meanwhile a rotary cover a abuts on a contact pin 15 and is opened. When the cassette 1 is taken out, the holder 6 is moved to the 1st position from the 2nd position. Thus the cover 2 energized usually in its closing direction is closed. Under such a condition, the cassette 1 is taken out to prevent such a case as the side part of the cover 3 is held by fingers. Thus, the cover 3 is kept within the holder 6 after the lock of the cover to its open position. Then the cover 3 is taken out together with the cassette 1 after the cover 3 is closed completely.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette holder for a cassette recorder using a tape cassette with a lid for audio use.

BACKGROUND OF THE INVENTION In recent years, cassette holders have been implemented in various forms in video recorders, audio cassette recorders, and the like.

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

Problems to be Solved by the Invention However, the newly proposed tape cassette has a rotating lid that opens and closes the front opening, and an opening on the bottom that is continuous with the front opening, and a slide that opens and closes the bottom opening. If you use a cassette holder like a conventional tape cassette (compact cassette), you can remove it by pinching the rear left and right sides of the sliding lid when it is open, and the bottom opening will open. It has been found that there is a problem in that there is a risk that the paper may be taken out without being removed.

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

Means for Solving the Problems In order to solve the above problems, the cassette recorder of the present invention opens the sliding lid by inserting a tape cassette and protects at least the side wall of the sliding lid in the open state. It is equipped with a structure that includes a wall.

According to the above-described structure, the present invention performs recording or playback at the second position where the tape cassette is moved together with the cassette holder in the direction perpendicular to the insertion direction after insertion, and when the cassette is removed, the same position as when the insertion is completed is performed. If you return it to position 1, the open tape cassette will be inside the cassette holder with the rear part of the cassette body excluding the sliding lid protruding, so if you pinch the rear part and take it out, you will be able to close the sliding lid when taking it out. This also prevents the sliding lid from being pinched and taken out with it open.

Moreover, by doing this, the tape cassette only needs to be moved by the cassette transfer means between the first position and the second position, and the tape cassette is automatically pushed out when it returns to the first position. Since it is no longer necessary to remove the cassette from the cassette holder with the sliding lid closed, the device can be configured extremely easily.

EXAMPLE Hereinafter, a cassette holder according to an example of the present invention will be described with reference to the drawings.

FIG. 3 is a top view of the proposed tape cassette with a lid, in which 1 is the cassette body, 2 is a rotating lid that opens and closes the front opening, and is always biased by a spring in the closing direction. FIG. 4 is a side view of the same, and numeral 3 denotes a sliding lid that opens and closes 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 it in the closed position. Figure 5 is its front view;
6 is a notch provided in the rotating lid 2, from which the front end of the sliding lid 3 can be seen. 6 is a notch also provided in the rotating lid 2, which allows the sliding lid 3 to be unlocked in both open and closed positions. The part opens into a viewing groove (not shown).

FIG. 6 is a side view showing a state in which the sliding lid 3 is locked in the open position, and FIG. 7 is a side view showing a state in which the rotating lid 2 is opened. As can be seen, the pivoting lid 2 can only be opened after the sliding lid 3 has been completely opened.

FIG. 1 is a side view of essential parts showing the tape cassette insertion/removal position of the cassette holder in the first embodiment of the present invention, that is, the first position. In Fig. 1, 1 is the cassette body which has been inserted into the cassette holder, 2 is the rotating lid, 3 is the sliding lid that is open, 6 is the cassette holder, and 7 is the cassette body.
is a cassette holder bottom plate, 8 is a contact portion for opening the sliding lid made by bending a part of the cassette holder bottom plate 7, and 9 is a part of the side wall of the cassette holder 6 so as to prevent the sliding lid 3 from being grasped with fingertips. The protective wall 10 urges the inserted tape cassette downward by a cassette pushing spring provided on the upper inner wall of the cassette holder 6. 11 is the rotation support shaft of the cassette 7) holder, 12 is the cassette holder bearing, 13 is the chassis, 14
a reel stand 15 which is driven in engagement with a tape hub (not shown) in the tape cassette and winds or supplies the tape;
is a contact bottle for rotating the lid to open.

With this structure, when the tape cassette 1 is inserted, the sliding lid 3 is first unlocked to the closed position (mechanism r is not shown), and then the sliding lid 3 is moved to the abutting portion 8. Opening begins when the front end of the lid 3 comes into contact with the sliding lid 3, 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 the predetermined performance position (second position), the rotating lid 2 hits the abutment pin 15 on the way. When the tape cassette is opened or used, when the cassette holder 6 is brought from the second position to the first position (Fig. 1), it is constantly biased in the closing direction and rotates. The lid 2 is closed and the state shown in FIG. 1 is achieved.

When taking out the tape cassette 1 from this state, since the side of the sliding lid 3 is not grasped with the fingertips, the process is the reverse of the insertion process, and after the sliding lid 3 is unlocked to the open position. Due to its own returning force in the closing direction and the frictional force, the cassette 7) stops in the holder and is completely closed, then taken out together with the cassette body.

As described above, according to this embodiment, the tape cassette 7) has a rotary lid that opens and closes the front opening, and a sliding lid that opens and closes the bottom opening and is placed in both the open and closed positions. By providing a protective wall that substantially covers at least the side wall of the sliding lid in the open state when the cassette has been inserted,
The sliding lid can be opened and closed by inserting and removing the tape cassette into the cassette holder.When taking out the cassette holder, the tape cassette is automatically pushed out after moving from the 8x2 position to the first position, and the sliding lid Since there is no need for a complicated mechanism such as closing and then removing the cover, the structure can be extremely simple.

FIG. 2 is a partial side view showing the main parts of a cassette holder according to a second embodiment of the present invention. In the figure, reference numeral 16 denotes a protection plate integrally constructed by extending not only the side wall portion of the cassette holder 6 but also the bottom plate, and prevents fingertips from touching not only the rear end side but also the bottom surface of the sliding lid 3. This is what I did.

The cassette holder configured as described above eliminates the possibility that when a tape cassette is taken out, the bottom surface of the sliding lid 3 is held down and the tape cassette is taken out while being locked in the open position.

Although the embodiment has been described using a rotating cassette holder, it may also be one that moves vertically in parallel.

Effects of the Invention As described above, the present invention includes a rotating lid that opens and closes a front opening;
The bottom opening opens and closes, and the mouth is in both open and closed positions.

By using a tape cassette with a sliding lid that can be removed, and a protective wall that substantially covers at least the side wall of the sliding lid in the open state when the tape cassette is inserted, the tape cassette can be removed. The sliding lid is locked in the open position! Since it is possible to prevent the product from being mishandled, the original purpose of the lid can be achieved.

In addition, since the sliding lid can be opened and closed reliably by simply inserting and removing the tape cassette, the device can be configured with a simple cassette transfer means that only moves the tape cassette together with the cassette holder between the first position and the second position. I can do it.
