Description

[Detailed Description of the Invention] The present invention includes a picture on the surface. The present invention relates to an audiovisual card playback device that uses an audiovisual card with letters, etc. drawn on it and a sound groove on the back side, and provides an excellent audiovisual card playback device that has a simple configuration, is equipped with a fully automatic function, has complete needle protection, and is convenient to carry. The purpose is to

Instead of the conventional playback device that consists of a turntable and a pick-up attached to the end of a fixed arm, a playback device was developed in which a pick-up that rotates with the turntable was attached to the turntable and played back a recording card. This is a card with pictures and text written on the same side as the sound groove, and for example, by placing the card on a desk and placing a playback device on top of it, you can play the sound while looking at the pictures and text. However, it was difficult to play while carrying it around, and the cards were large because the pictures and letters were on the same surface as the sound groove.
Also, if the relative position of the card and playback device is shifted during playback, the stylus may come off the sound groove, scratching the sound groove nonparallelly and damaging the sound groove, or scratching somewhere other than the sound groove, damaging the stylus. I had something to do. Furthermore, if you place the playback device on a desk or other place and start playing, the pick-up will rotate even though there are no cards, causing the stylus to scratch the surface of the desk, damaging the desk surface and the stylus. There are also drawbacks. In addition to the stylus, there is also a similar problem in aligning the center of the sound groove with the device. For example, when aligning using the outer diameter of the record, the outer diameter guide of the device may damage the sound groove,
Furthermore, when positioning is performed using the center of the record, there is a drawback that the sound groove may be damaged by the centering pilot pin provided on the device.

The present invention eliminates the above-mentioned drawbacks of the conventional art, and provides an excellent audio-visual card playback device that is simple in construction, completely protects the needle, is convenient to carry, and is fully automatic.
