Description

Tape cassette storage device of tray type magnetic record player {APPARATUS FOR COLLECTION OF TAPE CASSETTE OF TRAY TYPE TAPE RECORDER}

The present invention relates to a tray type magnetic recorder such as a digital video cassette recorder (D-VCR) using two types of tape cassettes of different sizes, and more particularly, a standard tape cassette and a small tape cassette. The present invention relates to a tape cassette storage device of a tray-type magnetic recording / reproducing machine which makes it easier to store and double convenience of use.

Recently, magnetic recording players such as VCRs, D-VCRs, HD D-VCRs, and camcorders have been widely used due to the improvement of overall living standards, and the magnetic recording players have a tape cassette in the magnetic recording player main body according to the storage method of the tape cassette. The front loading method of lightly pushing and the tray loading method using a tray which is moved back and forth in the main body of the magnetic recorder are known. Top loading methods for storing and side loading methods for storing tape cassettes in the lateral direction of the main body of portable camcorders are also applied.

The front loading method, the tray loading method, the top loading method, and the side loading method as described above are applied in consideration of various factors such as an installation environment, a use environment, a configuration, a function, and a production cost of the magnetic recording player.

In addition, the types of tape cassettes are also diversified due to differences in materials, recording methods, manufacturing methods, and recording prevention technologies in consideration of various needs of users, and the size of the tape cassettes is also diversified.

Therefore, in recent years, a technique has been attempted to selectively use tape cassettes of different sizes in a single magnetic recording player in addition to the technology improvement of the magnetic recording player.

However, in the magnetic recording player as described above, a technique is known in which two types of tape cassettes of different sizes are used in a magnetic recording player such as a front loading method, but two sizes are different in a tray loading type magnetic recording player. There is no known technique for using two types of tape cassettes. Accordingly, two types of tape cassettes of different sizes are used to meet various needs of a user. Magnetic recording player is required.

On the other hand, the broadcasting station is equipped with a magnetic recording and reproducing system in which two or more tape cassettes of different sizes are used by using trays, but the overall system is not only large but also very complicated in structure and too expensive. It was not suitable for public use.

Further, a technique for storing two types of tape cassettes in a cassette holder is disclosed in Japanese Patent Application Laid-open No. Hei 9-147464 (named "Cassette Mounting Device"). Contrary to the trend of miniaturization and thinning of the magnetic recording player due to the complex structure interlocked with each other, it does not contribute to the miniaturization and thinning of the magnetic recording player, but also increases the manufacturing cost and makes the three sides of the small tape cassette thin. By contacting the tray of thickness with the press-formed surface, there have been a number of problems such as causing scratches on three surfaces during repeated use, such as damaging the small tape cassette.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tape cassette storage device of a tray-type magnetic recording / playback device which can double the convenience of use by making it easier to store a standard tape cassette and a small tape cassette with a simpler configuration.

Another object of the present invention is to provide a tape cassette storage device of a tray type magnetic recording player which is capable of preventing damage to the small tape cassette by performing a rounding treatment on a portion in contact with three surfaces of the small tape cassette.
