, and the unlocking solenoid 88, respectively.

Next, the operation of the above embodiment will be explained with reference to FIG. When watching a video, first insert a coin, for example a 100 yen coin, into the coin slot 5. This inserted coin is detected by a coin detection switch 90, and a detection signal thereof is sent to a control circuit 91. The control circuit 91 starts a built-in timer and displays the remaining time on the display 4.

After inserting a coin, refer to the menu, decide on the video you want to watch, and press the selection button 2 corresponding to this video.

When the selection button 2 is pressed, the drum drive motor 3G rotates, so that the drum 30 containing a plurality of video cassettes rotates. The rotational position of the drum 30 is detected by a positioning projection 45 and a drum positioning switch 46.

Then, when it is detected that the cassette storage chamber containing the desired video cassette has moved to the loading position,
The control circuit 91 stops the rotation of the drum drive motor 36.

After the drum driving motor 36 stops rotating, the arm driving solenoids 62, 71 are energized to displace the cassette transfer means 50, 51, and the rubber belts 55, 56 and 70 are inserted into the cassette storage chamber through the notches. . At the same time, the lock release solenoid 88 is energized, so the flap plate 85 is opened by the lever 87, and the holding of the video cassette is released. Then, based on the signal from the cassette presence/absence detection switch 73, it is confirmed that the bidet cartridge is stored. Thereafter, the cassette transport motor 59 is started and rotates the rubber belts 55, 56 and 70, so that the video cassette is transported in a sandwiched state. The video cassette is taken out from the cassette storage chamber, moved toward the video deck 19, pushes open the front door 76 of the video deck 19, and is loaded into the loading chamber 77. When it is detected that the feeding of the video cassette is completed, the arm drive solenoid 62, 71 and the unlocking solenoid 88 are de-energized. As a result, the rubber belt 55
．． 56 and 70 are separated so as not to inhibit rotation of the drum 30. Further, the spring plate 85 provided in the cassette storage chamber returns to the locking position. Thereafter, the rotation of the cassette transfer motor 36 is stopped. The completion of feeding the video cassette is determined based on whether the cassette transport motor 59 has rotated for a predetermined time sufficient to feed the video cassette.

When a desired video cassette/mouth is loaded into the video deck 19, that is, when a predetermined period of time has elapsed after the sending of the video tape is completed, the control circuit 91 sends a playback start signal to the video deck 19. Play the video. This image is displayed on the cathode ray tube 14 when the television is in use. Then, when the remaining time displayed on the display 4 runs out, the reproduction of the video ends. Furthermore, when the feeding of the videotape ends during one viewing time, the video deck 19 automatically starts rewinding.
Start playing the video again from the beginning.

When the remaining time runs out, the eject button pressing solenoid 79 is energized, and the eject button 83 of the video deck 19 is pressed.

As a result, the video tape is ejected from the video deck 19, and the cassette position detection switch 74 is turned on. When this cassette I~position detection switch 74 is turned on, the control circuit 91 first operates the arm drive solenoid 62,
71 and the unlocking solenoid 88 are energized. Next, the cassette transfer motor 59 is energized to reverse the rotation, and the video cassette is returned to the empty cassette storage chamber.

When the loading of the cassette is completed, the arm drive solenoid 62, 71 and the unlocking solenoid 88
The power supply stops. At the same time, the rotation of the cassette transfer motor 59 is stopped, one sequence is completed, and a standby state is entered until the next coin is inserted. It is to be noted that whether or not the loading of the bidet power is completed is determined by whether the cassette position detection switch 74 is OFF and the cassette presence/absence detection switch 73 is ON.

(Effects of the Invention) The present invention having the above configuration allows a desired video cassette to be taken out from among a plurality of video cassettes and automatically loaded into the video deck.
A desired video can be easily selected and viewed without using a large-scale device as in the past.
