<p>PURPOSE:To eliminate a switching means such as a plunger and to simplify a constitution, and to miniaturize a reciprocating type cassette tape recorder to an extra-small size by executing switching operation of a first reel shaft and a second reel shaftly utilizing the rotational force of a motor. CONSTITUTION:The shifting action of a control plate and the holding action in each operating position are executed by utilizing the fitting force generated between a controlling gear and a first driving gear 5 or a second driving gear. The control gear to which the rotation of a motor is transmitted by engagement with the first driving gear 4 driven by the first motor 2 or a second driving gear 11 driven by the second motor 4 and a transmission gear that transmits rotation of the controlling gear to a first reel shaft 17 or a second reel shaft 21 are attached rotatably. Since the fitting force generated between the first driving gear or the second driving gear is utilized, the constitution is simplified, and effective for the miniaturization of a tape recorder.</p> |
