PURPOSE:To confirm simply the end of channel reservation by generating a confirmation tone only when all of channel reservation information is inputted while reservation moves from one to another channel. CONSTITUTION:A control circuit 20 having a program timer function for picture display has a CPU21, a ROM22, a RAM23 and an I/O port 24, a remote control signal from a commander is inputted from the input port side of the I/O port 24 and keys 28, 29 are connected in the receiver main body. The key 28 is a mode switching key and the key 29 is a timer key switching on/off a reservation timer. Then in order to supply a synchronizing pulse to a clock timer of the CPU21, an AC signal from a commercial AC source 37 is fed to a pulse circuit 38 to form a power supply synchronizing pulse. When the first event reservation is finished, only when all the event reservation information is inputted, the control circuit 20 generates a sound control signal to generate a confirming tone. |
