Abstract

PURPOSE:To always store an optional tape length by storing a time value inputted by an optional time inputting means in an input tape length storage means constituted not to lose storage contents even a main power source is cut off. CONSTITUTION:An input of an optional tape length is accepted by a tape length memory key 25d to be stored. When the key 25d is pressed, the acceptance of a tape length memory is performed in turn from n=1 to n=3, and their processing is over when the memory is full. Then, the tape length is accepted by a key 25b and an optional time input key 25c. When a tape other than that of 90min, 60min and 45min is often used, its time value inputted by the optional time inputting means 30 is stored in a input tape length storage part 33 by the tape length storage means 32. The number of pieces of music in a disk that can be reproduced within this stored time is calculated by a specific reproducing time dividing part 31, and their music numbers are stored. Since the storage contents in the storage part 33 are never lost even when the main power source is cut off, a value storage by a tape length specifying means 28 is specified when the power source is turned on again.
