<p>PURPOSE:To simplify the assembling and control of a magnetic recording/reproducing device with a compact and lightweight structure, by changing the relative position between a cassette holder and a rotating base plate while revolving them together when the base plate is turned to load a cassette. CONSTITUTION:A rotating base plate 24 containing a cassette cover 38 is revolved on the basis of a shaft part 26a which is fitted into a rotating center hole 24c. A cassette holder 22 is also revolved and controlled by a guide plate for its back and forth positions. The holder 22 shifts relatively pins 22a and 22b so that slits 24a and 24b get further away from the part 26a while moving down. In this case, the relative shift range does not cover up to the opening parts of slits 24a and 24b. Therefore pins 22a and 22b are never removed from long holes 24a and 24b after the holder 22 is once set into the plate 30. Printed base boards 35a-35d are connected to each other by a flexible base plate 36 and can be set at the top plate part of the device main body. This can reduce greatly the size and weight of a magnetic recording/reproducing device.</p> |
