<p>PURPOSE:To reduce the whole size of a device and to improve the operability by forming a perspective window, reproducing part and a high speed travelling part on the upper surface of a cassette holder part, and a main operation part also on the upper surface of the holder part. CONSTITUTION:When a reproducing button 11 is depressed, a projection 11a bends a moving contact piece 17 to connect contacts 18a, 18b of a keyboard switch 18 electrically, drives a motor 49, turns gears 42, 34, and then drives a reel board 30. When a quick traverse button 13 is pressed against the exciting force of a spring 25, a lower projection 27 is abutted to the head part of the reel board 30, the reel board 30 and a shaft 35 slide and fall the inside and outside of a boss 32 unitedly and a gear 33 is engaged with a gear 41. A conical part 35b closes a contact part 38 of a switch 39. After transferring once in the right direction along the outside of the conical part 35b, a locking plate 45 is engaged with a small diameter part 35a, and while holding the status by a spring 46, turns the reel board 30 at a high speed to execute the quick feeding of a tape. The rewinding operation by a rewinding button 14 is executed in the same manner. Since positive and negative revolution travelling reproducing buttons 11, 12, the quick feeding button 13 and the rewinding button 14 are arranged on the upper surface of the holder part 2, it is unnecessary to arrange these operation buttons on the side or back of the tape recorder or reduce the size of the operation buttons even if the body of the tape recorder is redued at its size almost close to the size of a cassette.</p> |
