ABSTRACT:
A tape recorder comprising first and second mode selecting bars for normal- and high-speed operations respectively, a solenoid, a switch for coupling thereto a signal indicative of the presence of a recorded material, and a spring-biased lever having a first magnetic arm portion and a second arm portion pivoted at a point therebetween. The lever is rotatable between a first position toward which its first magnetic arm portion is urged for making contact with the solenoid and a second position in which its first arm portion is away from and unaffected by the energized solenoid. The second arm portion of the lever is engageable with the second bar when the lever is in the first position together with the solenoid being simultaneously energized. A latch bar engages with the first bar when operated and engages with the second bar when the latter is exclusively operated. The lever is rotated to the second position when the first bar is released allowing the second bar to engage with the latch bar and rotated to the first position when the first bar is operated allowing the second bar to engage with the second arm portion upon energization of the solenoid and disengage therefrom upon its de-energization.
