PURPOSE:To easily recognize a track feed by a user by outputting the sound of a frequency corresponding to a speed mode in a track feed. CONSTITUTION:It is assumed that the user tires to perform a consecutive track feed, and a consecutive mode at a track feed speed L0 of one track feed per 1sec is set. In such a case, an optical signal 33 from a remote control part 31 is received at a photodetecting part 35, then being sent to a CPU 19, and at the CPU 19, a change-over switch S2 is connected to a capacitor C2 side (contact point (b)) by the second switch control signal 41. Also, an oscillator 45 starts its oscillation with a frequency f2 decided by the capacitance value of the capacitor C2. At the CPU 19, afterwards, by closing momentarily an opening/closing switch S3 by the third switch control signal 51, and outputting momentarily the sound of the frequency f2 different from that of a time when it is outputted in a single mode from a speaker 57, the user can recognize the setting of a consecutive mode L0.
