Abstract

PURPOSE:To attain also the loading of a second cassette without using an adapter by providing first-fourth positions and moving the cassette and a cassette holder to a fixed position on the using of first and the second cassettes. CONSTITUTION:When a second cassette 2d is inserted, a carrying arm 18a turns counter clockwise, and the cassette 2d moves from a first position indicat ed with a continuous line to a second position indicated with a broken line by a second carrying mechanism. At this place, a carrying means is formed with the carrying arm 18a, a pin 20a, a cassette holder 21a and a tape pulling out means 19a. Then, also the holder 21a comes up from the third position indicated with the continuous line to the second position indicated with a dotted line, and the second cassette and the holder 21a is coupled. Then, they are equivalent to the tape traveling route of a first cassette and a reel driving part, the second cassette comes down to the third position and is loaded. By the above-mentioned constitution, also the loading of the second cassette is attained without the use of an adapter.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording/reproducing apparatus using two compatible cassettes of different sizes.

2. Description of the Related Art In recent years, there has been a strong demand for video tape recorders (hereinafter referred to as VTRs or magnetic recording and reproducing devices) to be made more compact. For miniaturization, a tape reel that is smaller than a standard type tape cassette (hereinafter referred to as the first cassette) and that can house a magnetic tape similar to the magnetic tape of the first cassette and wind the magnetic tape therein. A small cassette (hereinafter referred to as a second cassette) having a cassette has been introduced and is widely used, especially for reducing the size and weight of camera-integrated VTRs. In order to record or play back the second cassette by installing it in a predetermined type of VTR that records and plays back the conventional first cassette, the second cassette must be inserted into the conventional first cassette as shown in FIG. Adapter 3 was required to convert it to 1 cassette.

Problems to be Solved by the Invention However, it is troublesome to use an adapter every time the second cassette is used, so it is possible to connect the first cassette and the first cassette with one VTR without using an adapter. 2
There is a strong desire for a VTR that can use both cassettes.

In view of the above-mentioned problems, the present invention provides a magnetic recording/reproducing device that can record or reproduce data by attaching both to one VTR.

Means for Solving the Problems In view of the above-mentioned problems, the magnetic recording/reproducing apparatus of the present invention moves from the first position in the same horizontal plane as the cassette insertion opening, which is the transport path of the first cassette, to the second position. A fourth position is provided in the same horizontal plane as the horizontal plane, which is separate from the path leading to the third position perpendicular to the horizontal plane, and
bringing a cassette holder to the fourth position when the first cassette is in use, the cassette holder being combined with the cassette to make the tape running path and reel drive section of the second cassette substantially equivalent to the first cassette; When using the second cassette, bring the cassette holder to a third position,
The second cassette moves from the first position to the second position, and in that state, the cassette holder moves from the third position to the second position.
By rising to the position, the second cassette and the cassette holder are combined and become equivalent to the tape running path and reel drive section of the first cassette, and then the second cassette is lowered again to the third position. , a second cassette is attached thereto.

Effect The present invention has the above-described configuration, and the first cassette and the second cassette are connected to each other.
Both of these cassettes can provide a device that can record or play back without the use of conventional adapters.
