<p>PURPOSE:To exactly perform the program searching of a requested message by correcting a memory value in a scanning time. CONSTITUTION:A microcomputer 1 reads out a prescribed regulated value in which a counter value at a tape starting end, and a time delay at the detecting time of a queue signal (mark E) for a regular memory point, are considered, as a correction value X. Afterwards, the microcomputer 1 sets the memory address of a memory on which the counter value of a rotation detecting pulse at every reproducing time of the mark E is stored, at zero, and reads out the counter value stored at the memory address, and performs a subtraction operation between the correction value X, and stores a subtracted result at the same memory address again. Thus, a value almost at the center position of a non-sound recording section immediately after the sound recording time of each mark E, is stored finally on the memory as the sectional point of the message.</p> |
