JPS5911584A - Disc built-in type magnetic tape cassette - Google Patents

Abstract

PURPOSE:To attain a simple construction without losing the simplicity of each loading and incorporating a magnetic tape and a magnetic disc, by freely turnably holding other end of an arm holding a magnetic disc to a cassette and interlocking the said arm with a loading operating member of the magnetic tape. CONSTITUTION:The magnetic tape 4 is tensed between a supply reel 2 and a winding reel 3 with tape guide pins 5a and 5b, and the magnetic disc 7 is supported freely rotatably to an arm 9 with a magnetic disc support section 8. Further, the arm 9 is supported freely turnably to the cassette 1 with an arm support shaft 10. In loading the cassette 1 to the device, a tape guide or the like for loading of the magnetic tape 4 is inserted to a cassette opening section 6, a drive member to turn the arm 9 is inserted, and this drive member is penetrated through an escope groove 12 of the cassette 1 and linked to an arm drive section 11 provided to the arm 9.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic tape cassette containing a magnetic disk, and particularly to a cassette half having a simple structure and suitable for loading a magnetic disk into a rotating cylinder.

Conventionally, as a medium for recording images, magnetic tapes are generally used for moving images, and magnetic disks are generally used for still images. Furthermore, both exist as independent systems.

At present, there are VFRs represented by p'BS and β systems, which use magnetic tape as a medium. All of these have a cassette containing magnetic tape stretched between two reels. The magnetic tape is then pulled out from the cassette and attached to a rotating cylinder on which a magnetic head is mounted for recording and reproduction.

On the other hand, those using magnetic disks have a cartridge containing either a hard or soft disc. The magnetic disk is then removed from the cartridge, frozen on the rotating shaft, and then recorded and reproduced by the magnetic head that comes into contact with it.

As described above, according to the prior art, only still images can be obtained using magnetic disks alone, and even if moving images are recorded and reproduced, long-term recording is extremely difficult due to the size of the magnetic disk. Further, although magnetic tape allows long-time recording and reproduction of still images, it has the disadvantage of long access times.

Therefore, a system that combines both moving images and still images is required, which can record and reproduce both moving images and still images at any time.

However, it is very inconvenient to operate the device if a cassette containing a magnetic tape and a cartridge containing a magnetic disk are respectively installed.

The purpose of the present invention is to eliminate the above-mentioned disadvantages of the prior art,
To provide a cassette with a simple structure that houses a magnetic tape and a magnetic disk and does not impair the ease of loading each in a magnetic recording and reproducing device capable of recording and reproducing both moving pictures and still images.

The present invention is characterized in that the other end of the arm that holds the magnetic disk is rotatably held in the cassette, and that the arm can be linked with a magnetic tape loading operation member.

An embodiment according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 shows a cassette containing a magnetic tape and a magnetic disk. FIG. 2 shows a state in which a magnetic disk is loaded.

In the figure, 1 is a cassette, 2 is a supply reel, 5 is a take-up reel, 4 is a magnetic tape, 5Vi tape guide pin, 6 is a cassette opening, 7 is a magnetic disk, 8 is a magnetic disk support part, 9 is an arm, 10 is an arm support shaft, 11 is an arm drive portion, and 12 is an escape groove.

In FIG. 1, the magnetic tape 4 is stretched between the supply reel 2 and the take-up reel 50 by tape guide pins 5α and 5h. Further, the magnetic disk 7 has a magnetic disk support section 8.
It is supported by the arm 9 in a υ rotation support. Furthermore, arm 9
is rotatably supported on the support set 1 by an arm support shaft 10.

With the magnetic disk 7 housed in the cassette 1, the arm drive section 11 provided on the arm 9 is in a position facing the relief groove 12 provided on the cassette 1. When the cassette 1 is installed in a device (not shown), the cassette opening 6 has a
Tape guides for loading magnetic tape 4 (
(not shown) is inserted, and at the same time, a driving member (not shown) for rotating the arm 9 is also inserted, and the driving member passes through the relief groove 12 of the cassette 1 and is provided on the arm 9. It is connected to the arm drive section 11.

As shown in FIG. 2, the state after the loading operation by the tape guides and drive members is such that the arm 9 rotates about the arm support shaft 10, and the magnetic disk 7 is moved to a predetermined position.

As described above, according to the present invention, a cassette with a built-in magnetic disk can be provided with a simple configuration consisting of only an arm for holding a magnetic disk and loading the magnetic disk to a predetermined position. The operational inconvenience of mounting two cassettes, each having its own, can be eliminated. Furthermore, if the member for driving the arm that holds the magnetic disk is also used as the loading member for the magnetic tape, the mechanism on the apparatus side is not complicated or eliminated.
