Description

[Detailed Description of the Invention] The present invention relates to a small-sized tape recorder, for example, a cassette-type tape recorder whose volume (dimensions) can be made extremely small.

Recently, there has been a strong desire to miniaturize audio products, and for example, in tape recorders, a standardized cassette installation volume (dimensions) is essential, so further miniaturization (i.e., miniaturization below the cassette dimensions) is essential. However, due to its structure, such microcassette tape recorders are inferior in performance and characteristics to cassette-type tape recorders. It was not suitable for listening to music etc.

The present invention has been developed in view of this point, and has made it possible to further downsize the cassette type tape recorder by using an extremely simple structure.

An embodiment of the present invention will be described below with reference to the drawings.

The figures show a compact tape recorder of the present invention, in which Figure 1 is a schematic plan view showing its volume reduced, Figure 2 is a schematic side sectional view thereof, and Figure 3 is a schematic diagram showing its volume expanded. The plan view and FIG. 4 are schematic side sectional views thereof.

Reference numeral 1 in the figure is a tape recorder body formed by a main body and a sub-body which will be described later, and its volume (dimensions) is configured to be freely contractable or expandable.

Reference numeral 2 denotes a main body equipped with a certain tape drive mechanism including magnetic heads 3, 3', vinyl rollers 4, flywheel 5, reel shafts 6, 6', etc. The main body 2 has various functions such as recording, playback, and rewinding. Operation buttons 7, 8, 9, etc. for performing operations are provided.

Reference numeral 10 denotes an auxiliary body which has a presser spring 12 for the cassette 11, etc., and rotatably supports the lid 13 on a shaft 14. The auxiliary body 10 has through holes 15, 15, 15,
15 and shafts 16, 16, 16, 16, etc., so as to be slidable in the left and right direction.

Therefore, the sub-body 10 and the main body 2 can be displaced relative to each other, and the volume (dimensions) of the tape recorder main body 1 can be varied.

That is, when the tape recorder is not in use and the cassette 11 is not installed, the secondary body 10 and the main body 2 are held by the operator's hand and slid in a direction toward each other, thereby making the tape recorder as shown in FIG. 1 or 2. As shown, the volume of the tape recorder main body 1 is reduced to make the width A of the tape recorder main body 1 smaller than the width of the cassette 11 for convenience of carrying. By sliding the sub body 10 and the main body 2 in the direction of separating them from each other by the operator's hand, the volume of the tape recorder main body 1 is expanded as shown in FIG. 3 or FIG. 4, and the tape recorder main body 1 is expanded. The width A of the cassette 11 is made larger than the width of the cassette 11, so that the mounting space for the cassette 11 can be occupied.

Therefore, when the volume (dimensions) of the tape recorder main body 1 is expanded, opening the lid 13 and loading the cassette 11 into the cassette loading space, pressing the operation button 8 allows normal playback operations to be performed. I can do it.

As described above, the compact tape recorder of the present invention has a box-shaped main body equipped with a tape drive mechanism such as a reel shaft and a magnetic head inserted into the front opening of the cassette;
A sub-body is provided with a rear presser spring of the cassette, and is slidably combined with the main body and relatively displaceable to reduce or expand the volume (dimensions) of the main body; a lid body rotatably provided on the secondary body to open and close the opening of the cassette mounting recess, and the main body and the secondary body are slid in a direction toward each other; When the main body becomes smaller than the dimension from the front end to the rear end of the cassette, the lid body covers the entire opening of the cassette mounting recess, and the main body and the sub body are slid in a direction to separate them from each other. When the main body size of the cassette becomes larger than the dimension from the front end to the rear end of the cassette, the lid body is arranged to cover the opening of the cassette mounting recess from the side of the cassette to at least the reel shaft portion. Therefore, when the volume (dimensions) of the tape recorder main body is reduced to less than the cassette dimensions, it is possible to reliably prevent dust etc. from entering the main body. ) is expanded to the minimum necessary volume (dimensions) commensurate with the cassette, there is no risk of the user's fingers accidentally touching the rotating reel shaft, and there is no risk of the user's fingers accidentally touching the rotating reel shaft, and there is no danger of the installed cassette being blocked by external obstacles. There is little possibility that the device will come into contact with the device, and therefore, it has an excellent effect in terms of safety and performance, even when used as a portable device with a cassette attached.
