<p>PURPOSE:To load a cassette automatically into a magnetic sound recording/ reproducing device by opening and closing a cassette storing door by a motor with the electrical signal of a noncontacting switch provided to detect the store of the cassette and then loading the cassette into the sound recording/reproducing device just by setting the cassette at the insertion slit at the upper part of a casette store part and then releasing a hand. CONSTITUTION:A cassette is inserted into a pocket 11 of a cassette store part 10 from the side of an arrow, and the cassette drops by its own-weight along a guide (not shown in the figure) of the pocket 11. The optical axis emitted from a light emitting diode 16a is cut off before the cassette reaches a prescribed position where its dropping is over. Then the cassette drops continuously down to its prescribed position. Thus the pocket 11 is completely stored. A motor 35 is energized with an electrical cassette store signal generated from a noncontacting switch 16, and a large gear 31 is revolved clockwise at a fixed speed. When the gear 31 has a 360 deg. revolution, a control switch 37 is changed over by a projection 36 which is unified with the gear 31. Then the motor 35 is stopped with a stop signal to complete a door closing action.</p> |
