<p>PURPOSE:To make ease of operation of the control mode changeover compatible with inhibition of unprepared mode changeover when the restraint of control mode is intended by combining changeover switches. CONSTITUTION:In throwing changeover switches 11a, 11b to the position A, a normal control signal and a special control signal are fed to fixed contacts. The normal control signal and the special control signal are selected optionally depending on the operating state of a switch 12, and they are fed to a reproducing section 3. In throwing the switches 11a, 11b to the position B, the special control signal is fed to both fixed contacts and the special control signal is fed to the reproduction section 3 independently of the operation of the switch 12.</p> |
