Tape case

Abstract

To improve workability in assembling a tape cassette by eliminating occurrence of disturbance in communicating with the tape driving device even if the direction of incorporating a memory board differs vertically and horizontally. The tape cassette 1 is equipped with the memory board 12 mounted with MIC 5 in which prescribed information is recorded or to be recorded in a cassette shell 2. The memory board is roughly rectangular and formed with a near rectangular spiral antenna patterns 14, 14. Each line segment pattern 14u, 14d, 14l, 14r of the antenna patterns is formed in a roughly axial symmetric relation relative to the center lines CLh, CLv vertically and horizontally.

Description

technical field [0001] This invention relates to tape cassettes. More specifically, it relates to a tape cartridge in which a memory chip on which predetermined information is recorded or can be recorded is built in a cartridge case formed by combining an upper case and a lower case, and relates to a technique for improving the mounting workability of the tape cartridge. Background technique [0002] Generally, a tape cassette is configured by supporting a reel on which a tape-shaped recording medium, such as a magnetic tape, is rotatably wound in a case. [0003] In some cases, such a tape cartridge is provided with a memory chip that records or can record information on the recording content of the magnetic tape or the type of the magnetic tape. [0004] Since information recording and reading toward such a memory chip is performed without contact with the tape drive side, a cassette-side antenna is provided on the tape cassette side, and an equipment-side antenna is prov...

Problems solved by technology

[0010] In particular, when the tape drive device and the tape cassette are miniaturized, if the two antennas are offset as described above, the communication efficiency will deteriorate and communication will become impossible.

[0011] Moreover, when the tape cassette is miniaturized, the memory substrate also tends to be miniaturized, and there is a problem that it is easy to mistake the direction when such a miniaturized memory substrate is assembled toward the case.

[0012] Furthermore, when the memory substrate is assembled into the case in the wrong direction, the positional relationship between it and the antenna on the tape drive side is shifted, resulting in communication failure or malfunction.

[0013] Therefore, so far, if the memory substrate is assembled in the wrong direction to the box case, it will become a fatal defective product. Therefore, attention must be drawn during assembly so that the direction is not mistaken, and there is an assembly operation of the tape cassette. issues like poor sex
