Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to simplification and miniaturization of the arrangement and structure around operating members for recording, playback, stopping recording and playback, fast forwarding, rewinding, and stopping fast forward/rewinding of a tape recorder. It is something.

There are various layouts of the operating members of conventional tape recorders, but for example, as shown in Figure M1, there are buttons with individual functions such as record button 1, playback button 2, recording and playback stop button 3, and fast forward and rewind buttons. There is also a fast forward/rewind button 4 which can be used separately. Buttons that operate independently require independent mechanisms, and when the fast forward/rewind button 4 is in the L'Wf position, it occupies a wide area of space. Historically, this has been an obstacle to reducing costs. In addition, as another example, the MF shown in FIG.
There are some devices that allow you to rewind, play, stop, and record by moving the device to one position, but it is difficult to incorporate fast-forwarding and cueing functions, the sliding amount is large, and it is difficult to use.

The drive member 14d rotates the brake lever 18 counterclockwise around the shaft 15d via the guide groove 18b, and pushes the brake 20 with the arm 18a to release the pressure on the gear 19 and enable rotation. At the same time, the power switch driving section 14e presses the fast-forward switch 22, bringing one end 21a into contact with the other end 21b and turning it on. To stop fast forwarding, the second slide switch 13 is returned to the 111 forward and rewind stop position tiffi 13b. Status! The river becomes yl'' in FIG. 6, the brake 20 presses the gear 19 again to stop it, and the fast forward switch 22 turns OFF. Next, in the case of cueing, in FIG. 3(b), the first slide switch 12 is set to the playback position 12c, and the second slide switch 13 is set to the fast forward position 13c. The internal state is shown in FIGS. 5 and 6 in which the playback state and the fast forward state overlap, that is, the pinch roller 32 and capstan 33 are in contact, and the recording/playback head 28 is connected to a magnetic tape (not shown). It is fast-forwarded in the form of touching. Therefore, the data is fast-forwarded while # is generated from the location t that has already been recorded.

In addition, as a modification of the embodiment, only the parts of the slide arm, that is, the guide member, slide arm, and positioning part, are used and combined with a recording head lever and an erasing head lever that perform conventional parallel movement movements for one-time use. You may do so.

Also, in some embodiments, a circuit or mechanism that prohibits fast forwarding or rewinding during recording may be incorporated, and a guide bin may be installed for the first slide arm, and A'f12G may be installed.
separate guides for the first or second slide arm;
Instead of using a set of guide bins, it is also possible to use a guide member such as providing a wall to guide the outer periphery.

As described in detail above, according to the present invention, functions such as recording, playback, fast forwarding, rewinding, and cueing are organized into two operating members and arranged side by side at 11111 of the case. The tape recorder can be made smaller by fitting into a small area on the surface of the computer, and it is easy to operate and learn. In addition, since the two sets of arms, positioning members, and guide members that communicate with the operating member are arranged in a Y-overlapping manner parallel to the side surface of the case and are elongated and unitized, the number of parts is small and can fit in a small space, and the cassette 45 and The cassette 45 can be placed in the elongated valley with the outer periphery of the case without overlapping with the cassette 45, making it easy to reduce the thickness and size. Also, the arm part is the driving member for the recording/reproducing head lever and the erasing head lever, and about 7 υ! 11 switch drive part, and the recording/reproducing lever, erasing head lever, and release lever are rotated by a common support, so the range of movement of the parts is small and the structure can be simplified. be.
