摘要： PURPOSE:To improve remarkably the operability by obtaining desired function through a single operation and executing the changeover from any of at least two functions into other function through the single operation. CONSTITUTION:When a cassette half is loaded to a tape deck 7 at first, a loading detection switch 21 supplies the 1st operation command signal to a tape power supply 24, a power voltage is fed to the tape deck 7 to attain tape reproducing state. In operating an eject key, an eject detection tuner 22 applies the 1st stop command signal to a tape power supply 24 to stop the tape deck 7. In operating the tuner switch 23 next, a power upply command is fed to the tuner power supply 25, an FM tuner section 9 becomes in the FM broadcast reception state. In operating the AM switch 4 to the FM broadcast reception state, an AM reception command signal is fed to the tuner power supply 25 from a control circuit 10 to stop the supply of the power voltage to the FM tuner 9 and the power is fed to the AM tuner 8 to attain the AM broadcast reception state.
