Abstract

PURPOSE:To prevent the miserasion of an ordinary tape, by opening a cassette holder with a push of an ejection button via a rotary member having two function parts, and at the same time, switching a function changeover switch to the ordinary tape side. CONSTITUTION:A rotary member 13 is attached rotatably to a shaft 15 of a chassis 6, and function parts 13a and 13b touch a function changeover switch 11 and a mobile member 16 respectively. The cam part of a cam plate 12 of an ejection button 10 touches a projected part 14. With a push of the button 10, the member 13 is turned counterclockwise at the cam part. Then the switch 11 is changed to the left ordinary tape side from a learning position, and at the same time a pin 5 of the member 16 moves downward to open a cassette holder. Therefore it is avoided that the tracks of the single side are mistakenly erased while the switch 11 is kept at a learning position despite an ordinary tape loaded.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a special program in which operation control signals are recorded in addition to the normal recording and playback function using a normal magnetic cassette tape (hereinafter referred to as general tape). The invention relates to a learning machine that also has a learning function that uses learning tapes.

Conventional configuration and its problems In recent years, dedicated pro-game cameras have been developed that record motion control signals (hereinafter referred to as control signals)! Many learning machines have been proposed that use learning tapes and control learning devices based on control signals to efficiently learn languages and the like.

A conventional learning machine will be explained below. Figure 1 is an external view of a conventional learning machine. 1 is the cabinet of the main body of the learning machine, 2 is an opening provided in the front of the cabinet 1, and 3 is a constant spring (Fig. This is a cassette holder that is energized by the cassette holder (not shown) and opens in response to the operation of an ejector (not shown), which will be described later.

Reference numeral 11 denotes a function changeover switch, which can be manually changed over regardless of the movement of the eject plate 4.

FIG. 4 is a diagram showing the operation system for each position of the function changeover switch 11. 0 When the function changeover switch 11 is switched to the left side, recording and playback operations using a general tape are enabled; When is switched to the right side, learning using the program learning tape becomes possible. Further, this switching is done manually based on the learner's judgment.

The operation of the conventional learning machine configured as described above will be explained below. First, when the eject button 10 is pressed, the eject plate 4 that is in contact with the cam plate 9 fixed to the eject button 10 slides along the cam portion 9a, and the pin 6 pivotally attached to the eject plate 4 also moves as shown by the arrow. The pin 6, which was linearly driven in the direction b) and engaged with the claw 3a of the cassette holder 3, moves and detaches from the claw 3a, and the cassette holder 3 is opened by the biasing force of a spring (not shown), and the cassette tape is can be attached and detached.

Here, we will explain about the learning-only program learning tape. First, a general tape, that is, one channel on which music, etc. is recorded p2) L and R for stereo recordings on rack
There are two tracks called ``,'' and audio is recorded and played on each track, but in a program learning tape, one of these two tracks is used to record the audio and signals from the learning instructor. This is recorded in advance, and the learner can record the audio on the other track.

On the other hand, when this learning machine is in the program learning operation system (with the function selector switch 11 on the right side), the cassette tape is assumed to be a program learning tape, so the track on the learner's side automatically enters the recording state. It is configured so that

However, in the conventional configuration described above, when playing a general tape, it is necessary to switch the function selector switch 11 to the "general tape" side, but it is necessary to switch the function selector switch 11 to the "program learning" side. It is also possible to drive the tape, but in this case one track is in the recording state, which poses a problem in that it is easy to cause a malfunction in which all previously recorded content is accidentally erased.

Purpose of the Invention The present invention solves the above-mentioned problems of the conventional technology.When the eject button is pressed, the function changeover switch automatically returns to the "general tape" side, thereby preventing accidental erasure of the general tape. The purpose is to provide a machine.

Structure of the Invention The present invention comprises: a cam plate fixed to an eject button and having a cam portion; a rotating member rotatably pivoted to a chassis and having two working portions different from the portion that contacts the cam plate;
The learning machine is equipped with a function changeover switch that contacts the first acting part of the rotary member, and a movable member that contacts the second acting part and is movable and that is linked to opening and closing of the cassette holder, and an eject button. When the rotary member is rotated, the rotary member is rotated, and the second acting part of the rotary member moves the movable member to open the cassette holder, and when the rotary member is rotated, the first acting part opens the function changeover switch. The device is characterized in that it is configured to be switched to a position where a function using a general tape is selected.
