Claims (1)

[Claims for Utility Model Registration] (1) A cassette reproducing means that outputs an end signal when the reproduction of the contents recorded on the cassette magnetic tape is completed, and a plurality of cassette magnetic tapes arranged vertically at predetermined intervals. a cassette storage case that is stored in a cassette storage case; a stage detection device that is provided near the cassette storage case and that raises and lowers the cassette reproducing means in the vertical direction and outputs a detection signal every time the cassette reproducing means moves through the predetermined interval; a current position detecting means for detecting the current position of the elevator mechanism; a cassette feeding mechanism for extracting a cassette magnetic tape from the cassette storage case and inserting it into the cassette reproducing means; and the cassette storage case. A control circuit for an automatic cassette exchange/playback device, comprising selection command means for issuing a cassette selection command for selecting any one of a plurality of cassette magnetic tapes, the control circuit comprising: In response to a selection command, the current position of the elevator mechanism is determined based on the output of the current position detection means, and based on the determination result, whether the elevator mechanism should be raised or lowered. an elevator mechanism control means that raises or lowers the elevator mechanism based on the determination result, and stops the elevator mechanism at a selected cassette magnetic tape storage position according to the detection output of the stage detection section; In response to the stop of the elevator mechanism, the cassette feeding mechanism is controlled to extract the selected cassette magnetic tape and insert it into the cassette reproducing means, and in response to the output of an end signal from the cassette reproducing means. and cassette feeding mechanism control means for controlling the cassette feeding mechanism and storing the cassette magnetic tape ejected from the cassette playing means in a corresponding position of the cassette storage case. (2) The elevator mechanism control means causes the elevator mechanism to move up and down at high speed when the elevator mechanism is further away from the storage position of the cassette magnetic tape for which the selection command has been given, and to raise and lower the elevator mechanism when the elevator mechanism approaches the storage position. A control circuit for an automatic cassette exchange/reproduction device according to claim 1, wherein the mechanism is moved up and down at low speed. (3) The selection command means includes content selection command means for selecting one of a plurality of contents recorded on the selected cassette magnetic tape, and further includes a content selection command means for selecting one of a plurality of contents recorded on the selected cassette magnetic tape, and further includes a content selection command means for selecting a blank part in the content reproduced from the cassette reproduction means. a cue detection means for detecting this when there is a content selection command, and a fast-forward control means for fast forwarding the cassette playback means until the cue detection means detects the selected content in response to a selection command from the content selection command means. A control circuit for an automatic cassette exchange and playback device according to claim 1, comprising:
