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. This is to ensure that it is 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 length of contact 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 the second and third embodiments of the present invention will be described below.
This will be explained with figures. Reference numeral 15 denotes a rectangular column that is formed integrally with the cassette case 1 and is elongated in the left-right direction. Reference numeral 16 denotes a pad holder made of a soft elastic material such as rubber, which has through holes 17 and 18 formed in the front and back that pass through it in the vertical direction, and a pad made of felt or the like on the front surface of the pad holder 16. 19
is installed.

The shape of at least the rear through hole 17 of the pad holding base 16 is the same as the shape of the pillar 15, and its dimensions are slightly smaller than the dimensions of the pillar 15.

The pad holder 16 is held by having its through hole 17 fitted into the pillar 15, and in this case, the lower surface of the pad holder 16 is connected to a protrusion 20 that is integrally formed with the cassette case 1 behind the pillar 15. A gap is formed between the front part of the pad holder 16 and the cassette case 1, so that the front part of the pad holder 16 is closed to the through hole 18.
Together with the formation of , it can be freely deflected in the front-back direction.

Consisting of the above configuration, the pad holding table 16
Since it is elastically held against the support column 15, a reliable holding state is obtained, and it does not fall off during assembly or wobble when subjected to vibration, and can be easily installed. . When the head is inserted, the pad holder 16 whose front surface contacts the pad 19 is deformed to follow the front surface of the head due to the presence of the through hole 17.
Reference numeral 9 is a member that presses against the front surface of the head and ensures reliable contact with the head.

Note that by forming a taper at the tip of the support column 15, the work of inserting the pad holding base 16 can be easily performed.

As described above, the present invention makes it possible to extremely easily obtain a pad holder that fits well against the front surface of the head.Moreover, it is easy to assemble and can securely hold the pad, and its effects are great. It is.
