Description

[Detailed Description of the Invention] The present invention relates to a tape cassette, and its purpose is to make the pad constituting the cassette more easily conform to the curved surface of the front surface of the magnetic head, thereby ensuring more secure contact of the magnetic tape to the front surface of the magnetic head. It is designed so that it can be held securely without shifting its position.

A conventional tape cassette is constructed, for example, as shown in FIG. In other words, 1 is a cassette case, 2 is a reel hub 3, 4 is a magnetic tape wound and stored in the case 1, 5 to 8 are tape guide pins, and 9 is a pad spring held in a holding part 10 integrated with the case 1. Solid rectangular parallelepiped rubber pads 11 and 12 are attached to both ends of the spring 9. When the above-mentioned cassette is attached to a tape recorder and the magnetic head is advanced, the magnetic head is inserted through the openings 13 and 14 at the front of the cassette and is inserted into the pad 1.
In this case, due to the hardness of the pad itself and the hardness of the spring 9, the contact length between the tape 2 and the front surface of the head is extremely short, and if the head is misaligned or angularly displaced, The contact of the pad with the head becomes uncertain, and there is a drawback that the state of contact between the tape 2 and the head becomes unstable.

The present invention eliminates such conventional drawbacks, and an embodiment of the present invention will be described below with reference to FIG. 2.

Reference numeral 15 denotes a support body formed integrally with the cassette case 1, and a slit 16 is formed in the center of the support body 15.

A pad holder 17 is made of a soft elastic material such as rubber, and a pad 18 made of felt or the like is attached to the front surface of the pad holder 17.
A hollow portion 19 is formed in the vertical direction of the central portion of 7. Furthermore, a neck portion 20 is formed at the rear of this pad holding base 17.

The pad holder 17 having the above structure has the pad 18 attached thereto, and its neck portion 20 is fitted into the slit 16 of the support 15 to be supported. In this case, the pad holder 17 has elasticity, so it can grip the support 15 and be securely attached.

When the pad holder 17 is attached, the pad holder is made of a soft elastic material and has a hollow part 19, so that when the head comes into contact with the pad 18, it follows the front surface of the head. The pad 18 is deformed to ensure that the pad 18 is pressed against the front surface of the head.

Incidentally, by providing a taper at the upper end of the slit 16 of the support body 15, the work of inserting the pad holder 17 can be facilitated.

As described above, the present invention allows the pad holder to be installed extremely easily, and since the pad holder is made of a soft elastic material, the pad fits comfortably against the front surface of the head, resulting in a stable pad pressure contact state. can be obtained, and the effect is great.
