Abstract
A magnetic recording and/or reproducing apparatus which includes a rotary magnetic head device, a reel block base plate provided on a chassis plate and having a pair of reel blocks horizontally reciprocable relative to the rotary magnetic head device and operatively engaged with a pair of tape reels of a tape cassette, a cassette holder which is supported by a supporting arm on the chassis base plate so as to be vertically movable relative to the reel block and in which the tape cassette is inserted and retained, an operating mode changeover lever for selecting the various operating modes, including constant speed running, rapid feed and rewind modes, for the magnetic tape pulled out of the tape cassette and loaded into the predetermined tape path, and a drive gear driven into rotation by a driving electric motor, wherein the drive gear is operatively associated with the supporting arm and the reel block base plate. The drive gear is driven into rotation to cause vertical movement of the cassette holder and the reciprocating movement of the reel block base plate. An operating lever adapted for being turned by the drive gear is operatively associated with the operating mode changeover lever, and turned to shift the operating mode changeover lever to select one of the predetermined operating modes. In this manner, the operations of loading the tape cassette and the magnetic tape and of selecting the operating mode may be performed by one and the same driving motor to reduce the number of the driving motors and the size and the thickness of the apparatus, while the cassette attachment and detachment and magnetic tape loading and unloading operations can be performed expeditiously.
