Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cassette-type tape recorder that can simultaneously load a plurality of tape cassettes.

[Technical background of the invention and its problems]

When you want to record i+ on several magnetic tapes at the same time, or when you want to record on multiple tapes by 1 inch while playing back one tape, so-called guibingke.
i It is necessary to prepare all the tape recorders of multiple units, or prepare a tape recorder with the mechanisms of multiple units combined into one unit.

However, not only when using multiple tape recorders, but even when using a tape recorder that combines the mechanisms of multiple units into one ICL, a large installation area is required, the cost is high, and the operation of multiple units is complicated. becomes.

[Purpose of the invention]

The present invention was developed based on these circumstances, and its purpose is to allow simultaneous recording and diving by loading multiple tape cassettes at the same time, while requiring a footprint equivalent to one conventional device. To provide a complete cassette type tape recorder that is easy to use, can be manufactured at low cost, and is easy to operate.

[Summary of the invention]

In order to achieve the above object, the cassette type cheap recorder of the present invention has a plurality of take-up reel shafts arranged coaxially so that a plurality of tape cassettes can be loaded in multiple stages, and a cassette shaft that can accommodate a plurality of tape cassettes. The tape rollers are long so that the cassettes can be shared, and the pinch rollers and magnetic heads are also provided in multiple stages to correspond to each tape cassette.

[Embodiments of the invention]

Examples of the present invention will be shown below.

FIG. 1 schematically shows the mechanism of a cassette tape recorder, and FIG. 2 is a sectional view taken along line II--II of FIG. 1.

The lower take-up reel shaft 6a and the lower supply reel shaft 8aVC are loaded with the lower tape cassette 1oa, and the upper take-up reel shaft 6b and the upper supply reel shaft 8bVC are loaded with the upper tape cassette job.

Further, FIG. 3 is a sectional view taken along line Tll-111 in FIG. 1, and as shown in this figure, a capstan shaft 11 is rotatably attached to the cheap record board 1 via a bearing 12. This capstan shaft 11 protrudes long from the upper surface side of the tape recorder board 1 and connects the two tape cassettes 10a.

10b. A flywheel 13 is fixed to the lower end of the capstan shaft 1) on the lower surface side of the tape recorder board 1.

FIG. 4 is a view taken along arrows 1--2 in FIG. 1, and numeral 14 in the figure represents a head mounting plate attached to the upper surface of the tape recorder board 1 so as to be movable forward and backward. On this head mounting plate 14 are two magnetic heads 15a.

15b is the two tape cassettes 10a.

They are installed in two stages via odor attachments 16 so as to correspond to 1Ob. In the diagram, reference numeral 17 denotes a pinch roller support that is rotatably attached to the tape recorder board 1 about a shaft 18, and two pinch rollers 19a and 19b are commonly attached to the rotating end of this support 17. It is attached via the shaft 20f of. And these pinch rollers 19a, 1

It is provided so that the capstan shaft 11VC is separated by Jtp in accordance with iII. The engagement end of the pinch roller support 17 is engaged with a part of the head mounting plate 14, and as the head mounting plate 14 moves in 011, the pinch roller support 17 rotates and the pinch roller is rotated. 19a,
The pinch rollers 19a and 19 are brought into pressure contact with all the capstan shafts 19b, and as the helad is moved back and back to the attached plate 14, the pinch rollers 19a and 19
It is configured to be separated from the bf capstan shaft 11.

Further, FIG. 5 shows a cassette holder f-21f, which has two tape cassettes 10a.

It has an inner partition plate 22 to accommodate a 10bf pull-out type tape cassette 10t+ on the bottom plate 23 and inner partition plate 22, respectively, and a tape cassette 10t+ on the reel 26 of 10b. A bearing metal 27 is also fixed.

Therefore, the tape cassettes 10a and 10bf of 21 times are accommodated in this cassette holder 21, and this is attached to the reel shaft 6a
