Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to tape cassettes for video, audio, and the like.

[Summary of the invention]

The present invention provides a tape cassette for video, audio, etc., in which a memory element is installed in the housing housing the tape, and tape playback mode information is stored in the memory element. This improves operability.

[Conventional technology]

Conventionally, tape cassettes used in video tape decks have had a shape as shown in FIG. 8, for example. In FIG. 8, (11 indicates a video tape cassette, and this video tape cassette +1) has a cassette body (2) composed of an upper half (2a) and a lower half (2b) made of ABS resin or the like. There is.

Two reels (3) are arranged inside this cassette body (2), and magnetic tape (not shown) is wound onto these two reels (3) with one end and the other end locked. has been done.

A front cover (4) is attached to the front of this cassette body (2).
) is attached, and the cassette I/main body (2) and front cover (4) are attached.
This constitutes the housing of this cassette tape 11). The front cover (4) is designed to rotate upward and open only when this videotape cassette (1) is installed in the deck. The magnetic tape protected by (4) is exposed from the cassette body 2), and the exposed magnetic tape is pulled out and wound around the rotating head drum of the deck to record and reproduce video signals and the like.

(Problems to be Solved by the Invention) By the way, with this type of videotape cassette (1), it will be difficult to manage this cassette unless the contents recorded on the cassette can be understood without being played back. It is inconvenient. However, the only way to do this with conventional cassettes is to write the contents directly in letters on a label (5) attached to the top surface of the cassette body (2). The work of writing to this label (5) is extremely time consuming, and due to space constraints, it was not possible to write much data.

In order to solve this problem, the present applicant has previously proposed a videotape cassette equipped with electronic circuit components capable of storing predetermined signals, as shown in Japanese Patent Application No. 60-298306. If a memory element with a large storage capacity is installed as the electronic circuit component, various data can be stored, and the effort of writing data on the label can be saved.

However, using this type of memory element simply for writing record data instead of a label has the disadvantage of being wasteful in terms of manufacturing cost, storage capacity, etc.

In view of the above, an object of the present invention is to provide a tape cassette in which memory elements can be used effectively.

[Means for solving problems]

The tape cassette of the present invention is a tape cassette constructed by storing a tape in a housing (2), as shown in FIG. ) is configured to store tape playback mode information.

[Effect]

According to the tape cassette of the present invention, the playback mode can be automatically set based on the playback mode information stored in the memory element (6), and the operability of the tape deck using this tape cassette is improved.
