Title: Sound volume controller
Inventor: ISHII TOMOHIDE
IPC: H03G3/02
Filed: 1985-05-10
Abstract: PURPOSE:To output a desired minimum sound volume with a simple operation by providing a time waiting/input detecting means so as to detect the presence of a switch input within a prescribed time thereby applying sound volume setting accordingly. CONSTITUTION:A microcomputer means 3 is provided with the time waiting/ input detecting means 16. When a power application detecting means 11 detects the application of power at first, the means 11 sends a signal to a sound volume setting means 12 to bring the sound volume to a minimum level. A signal is given to the time waiting/input detection means 16 at the same time so as to detect a signal of the input means 2 while awaiting a prescribed time (1sec). When no signal exists, a signal is given to a read control means 13 to read a signal representing a sound volume level stored in a storage means 4 and the sound volume is set to a sound volume setting means 12. When the signal exists, since no signal is sent to the read control means 13, the sound volume setting means 12 remains at the minimum sound volume. Thus, when there is a desire to raise minimum sound at application of power at night, it is realized by a simple operation.
