Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an audio-visual card playback device that uses an audio-visual card with pictures, letters, etc. drawn on the front side and a sound groove on the back side, and has a simple configuration when no card is inserted. The purpose of this is to configure the game so that play operations cannot be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An audiovisual card reproducing apparatus according to the present invention will be described below with reference to drawings of an embodiment.

Reference numeral 1 indicates the main body of the device with a housing, 2 indicates a slit for inserting an audio-visual card formed near the front of the main body 1 of the device, and 3 indicates an audio-visual card inserted into the slit 2, with pictures, letters, etc. drawn on the front surface, and sound on the back surface. an audiovisual card to which a vinyl record with grooves is attached;
Reference numeral 4 denotes a see-through window formed at the front of the device main body 1 at a position facing the surface of the audiovisual card 3 inserted into the slit 2, and 5 is rotatably mounted within the device main body 1, facing the see-through window 4. The turntable 6 is horizontally rotatable around a shaft 7 formed on the turntable 5, and vertically rotatable around a shaft 9 of a shaft attachment part 8 fitted to the shaft 7. pickup, 10 is turntable 5
11 is a slip ring mounted on the rotating shaft 12 of the turntable 5 and electrically connected to the output end of the pickup 6; 13 is in constant contact with the slip ring 11; 14 is the motor, 15 is the motor 1
4 and the turntable 5, 16 is a play button, 17 is a chassis, 18 is a play slide plate slidably fixed on the chassis 17, and 19 has one end inserted into the slit 2 and the other end. A to chassis 17
An interlocking member 21 is fixed so as to be slidable in the direction and biased by a spring 20 in the direction of pushing out the card.
9 is a stopper fitted into a notch 19-a formed in the slit 2, and when the audiovisual card 3 is inserted into the slit 2, it rotates in the direction B around the shaft 22 in conjunction with the interlocking member 19, The other end operates so as to be out of the operating range of the play slide plate 18.

23 is a leaf switch for controlling the power supply to the motor 14, which is attached to the chassis 17 and is formed by two contact pieces 24 and 25 facing each other and a holding part 26 that holds one end of these contact pieces 24 and 25; 27 is a stopper attached to the tip of one contact piece 24 constituting the leaf switch 23; 28 is a protruding piece that engages with a notch 5-b formed in the collar surface 5-a of the turntable 5; The reset member 29-a attached to the tip of the other contact piece 25 is connected to the spring 3 through a pin 31 formed on a part of the tone arm 30.
a cam portion for returning the pickup 6 against the force 29;
-b is a cam portion that comes into contact with the cut-and-raised portion 18-a of the place land plate 18 and moves the reset member 29 and stopper 27 downward in the direction C by the pressure of the play slide plate 18.

In the above embodiment, in the steady state, the stopper 2 attached to the tip of one contact piece 24 constituting the leaf switch 23
The protruding piece 28 of No. 7 fits into a notch 5-b formed in the collar surface 5-a of the turntable 5, and the contact piece 24 is slightly curved downward.

Since the play button 16 is not pressed, the other contact piece 25 is in a normal state, and therefore is not in contact with the one contact piece 24, and the leaf switch 23 itself is in an OFF state.

In this state, as shown in FIG. 2, the pin 31 formed on a part of the tone arm 30 is in contact with the reset member 29 provided on the other contact piece 25,
is fixed at the tip of the pickup 6 or at a position that does not protrude from the through hole 10 formed in the turntable 5.

On the other hand, when the audiovisual card 3 is not inserted into the slit 2, it is moved to the right side in FIG. It is within the operating range of 18.

Therefore, in this state, even if an attempt is made to operate the play slide plate 18 by pressing the play button 16, the tip of the play slide plate 18 immediately comes into contact with the other end of the stopper 21, and the play slide plate 18 cannot be operated.

Now, if the audio-visual card 3 is inserted into the slit 2, the connecting member 19 is pushed by the tip of the audio-visual card 3 and moves to the left side in FIG.

Therefore, the stopper 21 is rotated about the shaft 22 in the direction of arrow B, and the other end of the stopper 21 is moved to a position out of the operating range of the play slide plate 18.

Therefore, if you press the play button 16 in this state,
The play slide plate 18 moves in the direction of arrow D in FIG. 3, and the cut and raised portion 18-a presses the cam portion 29-b of the reset member 29.

Therefore, the other contact piece 2 constituting the leaf switch 23
5 is bent greatly downward, and the other contact piece 25
comes into contact with one of the contact pieces 24, causing the one contact piece 24 to further curve downward significantly.

As a result, the leaf switch 23 is turned on and power supply to the motor 14 is started, and one of the contact pieces 24 is bent greatly downward, causing the protrusion 28 of the stopper 27 to
The notch 5 formed in the collar surface 5-a of the turntable 5
-b, the rotation prevention of the turntable 5 is released, and the turntable 5 is rotated by the motor 14 in the direction of the arrow in FIG.

Then, when the other contact piece 25 is bent significantly downward, the engagement between the reset member 29 and the pin 31 is released, and at the same time, the tip of the pickup 6 protrudes from the through hole 10, and the pickup 6 The tip of the slit 2 engages with the sound groove of the audiovisual card 3 inserted into the slit 2.

Therefore, the sound groove is scanned by the pickup 6, and the signal recorded in the sound groove is reproduced and extracted.

As described above, in the above embodiment, when no card is inserted, the play slide plate 18 is prevented from operating by the stopper 21, and playback by the pickup is impossible. On the other hand, when a card is inserted, The interlocking member 19 slides against the spring 20 by the end face of the card, and the stopper 21 rotates in the B direction accordingly, allowing the play slide plate 18 to perform a series of operations.

As is clear from the above embodiments, the audiovisual card reproducing device of the present invention has a simple mechanism that prevents damage, completely protects the needle when no card is inserted, has excellent operability, and can be miniaturized. It can be used as a music playback device or an educational device.
