JPS62120661A - Cassette holder - Google Patents

Abstract

PURPOSE:To open/close precisely a sliding cover by loading/unloading of a tape cassette into/from a cassette holder without applying any change to the tape cassette side by forming a high frictional member on a guide surface to which the tape cassette is to be pressed by a tape cassette pressing means. CONSTITUTION:The high frictional member 9 is formed on the lower surface of the loading guide of the cassette holder 6. When the tape cassette 1 is inserted, the sliding cover 3 is unlocked from the closed position at first, and then the front end part of the sliding cover 3 is abutted upon an abutting part 8 to start the opening of the cover 3, and at the end of insertion, the cover 3 is completely opened and locked on the opened position. When the cassette holder 6 is rotated in the clockwise direction and reached to a prescribed position for play, a rotary cover 2 is abutted upon an abutting pin 15 on the way and opened.

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 cassette recorders, audio cassette recorders, and the like.

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

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 the one used for conventional tape cassettes (compact cassettes), you will end up pinching the rear left and right sides of the sliding lid when it is open, leaving the bottom opening open. It has been found that there is a problem in that there is a risk of it being taken out.

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 holder of the present invention opens the sliding lid by inserting the tape cassette, and
A high friction member is provided on the lower surface of the tape cassette insertion guide of the cassette holder so that the sliding lid can be reliably closed during removal.

Operation With the above-described configuration, the present invention performs playing at the second position where the tape cassette is moved together with the cassette holder in a direction substantially perpendicular to the insertion direction after insertion, and when the tape cassette is removed, it is played at the same position as when the insertion was completed. After returning to position 1, pinch the rear part of the tape cassette body protruding from the cassette holder and take it out.The sliding lid will hold the cassette until it is completely closed due to the frictional force between the bottom surface of the sliding lid and the high friction member. It will remain in the holder and be removed once it is completely closed.

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 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 it in the closed position. Figure 6 is its front view;
6 is a notch provided in the rotating lid 2, into which the front end of the sliding lid 3 can be seen; 6 is a notch also provided in the rotating lid 2, and is a lock release part for the sliding lid 3 in both open and closed positions. It opens into a groove (not shown) through which the window can be seen.

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, reference numeral 1 denotes a cassette body which has been inserted into the cassette holder. 2 is a rotating lid, 3 is an opened sliding lid, 6 is a cassette holder, 7
is a cassette holder bottom plate, 8 is a sliding lid opening contact part made by bending a part of the cassette holder bottom plate 7, and 9 is a high friction member provided on the lower surface of the insertion guide of the cassette holder 6, made of rubber, vinyl chloride, etc. It is in the form of a sheet or band.

1o urges the inserted tape cassette downward by a cassette pushing spring provided on the upper inner wall of the cassette holder 6. Reference numeral 11 indicates a rotating support shaft of the cassette holder, 12 indicates a cassette holder bearing, 13 indicates a chassis, and 14 engages with and drives a tape hub (not shown) in the tape cassette to wind up or supply the tape. The reel stand 15 is a contact bin for rotating and opening the lid.

With this structure, when the tape cassette 1 is inserted, the sliding lid 3 is first unlocked to the closed position (the mechanism is not shown), and then the sliding lid 3 is slid into 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. It is open to contact.

When taking out a 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 normally biased in the closing direction, closes. The state shown in Figure 1 will be reached.

If the tape cassette 1 is removed from this state, the process will be the reverse of that when it was inserted, even if the fingertips reach the sides of the sliding lid 3. That is, after the sliding lid 3 is unlocked to the open position, it remains in the cassette holder due to the return force of the opening in the closing direction and the frictional force, and after being completely closed, it is taken out together with the cassette body.

As described above, according to this embodiment, a tape cassette with a rotating lid that opens and closes the front opening and a sliding lid that opens and closes the bottom opening and is locked in both open and closed positions is used, and the cassette holder A cassette holder that can be reliably opened and closed by the frictional force between the sliding lid and the high friction member by inserting and removing the tape cassette in the main plane direction can be realized with an extremely simple configuration.

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

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

Effects of the Invention As described above, the present invention includes an insertion guide means for inserting and guiding a tape cassette in its main plane direction, a tape cassette pressing means for pressing the inserted tape cassette in a direction perpendicular to the insertion direction, and a tape cassette By providing a high friction member on the guide surface that is pressed by the tape cassette pressing means, it is possible to reliably open and close the sliding lid by inserting and removing it into the cassette holder without making any changes to the tape cassette side. can.
