Problems solved by technology

[0005] However, in recent years, the following problem has occurred in connection with the positioning hole and the ID hole: that is, although the amount of information required for the cassette tape tends to increase with the diversification of recording methods and recording densities, The space required to form the positioning hole and the ID hole on the tape case is narrowed, and the tape cassette tends to be miniaturized

Embodiment Construction

[0041] Next, embodiments of the magnetic tape cassette of the present invention will be described with reference to the accompanying drawings.

[0042] refer to figure 1 , 2 and 8, the cassette tape 10 has a tape case 20 in the shape of a thin case. Tape reels 40 and 50 around which a magnetic tape 30 characteristic of a tape-shaped recording medium is wound are rotatably accommodated in a tape case 20 . The cassette tape 10 also has a front cover 60 for covering the front surface side of the magnetic tape 30 positioned along the front surface of the tape case 20 and a rear cover 70 for covering the rear side of the magnetic tape 30 . The slider 80 is supported on the tape case 20 in a forward and backward movable manner. The rear cover 70 is integrally formed on the slider 80 , and the front cover 60 is rotatably supported at the front end portion of the slider 80 .

Abstract

Disclosed is a tape cassette in which two positioning holes is formed in the back surface of a cassette shell. One of the two positioning holes is formed into a circular shape and the other is formed into a long-hole shape. The positioning hole formed into the long-hole shape is divided into two parts in the major direction of the long-hole. An about half of the long-hole shape is used as a positioning hole and an about remaining half thereof is used as an information detecting ID hole for providing various kinds of information. A removable block piece is provided on an opening portion of said ID hole. With this configuration, the ID hole can be surely provided in the tape cassette, even if the tape cassette is miniaturized.

Description

technical field [0001] The present invention relates to a new type of magnetic tape cassette, and more particularly to a technique for miniaturizing a magnetic tape cassette formed with positioning holes for positioning the magnetic tape cassette in a tape drive and information detection for providing various information hole (ID hole). Background technique [0002] The magnetic tape cassette is constructed such that two reels on which the magnetic tape is wound are rotatably accommodated in a magnetic tape case, and the magnetic tape case generally consists of a lower case and an upper case. [0003] The lower shell of the tape case has two positioning holes for positioning the tape cartridge on the tape drive when the tape cartridge is placed in the tape drive, and an ID hole for detecting the ID on the tape cartridge. various information. [0004] On the other hand, the tape driving device is provided with two positioning pins, which are inserte...
