<p>PURPOSE:To simplify the constitution of a switching mechanism part by displacing the sliding substrate of the first tape recorder part to the operation position by the rotation of a cam accompanied with the rotation of a switching gear from the holding position to the operation position and making a constant- speed driving mechanism of the second tape recorder part unoperated. CONSTITUTION:When a solenoid plunger 66 is in the sucking operation state, that is, when a control pin provided on a control member 68 is brought into contact with a cam 65 to hold a switching gear 60 in the operation position, positions of respective cams and a tooth omitting part 62 are related to one another so that a restoring rotational force is given to the switching gear 60 by the contacting force of a control lever 72 to a cam 63. When an operation button 8 for reproducing is depressed to supply power to a motor 32, the rotation is transmitted to a flywheel 30, namely, a capstan 19 through a belt 33 and is transmitted to a take-up reel base 13 through a pulley 47 and a driving roller 46, and a magnetic tape is driven in a constant speed, and the first tape recorder part 2 is set to the reproducing operation state.</p> |
