Title:
FADER DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/094124
Kind Code:
A1
Abstract:
A motor (20) moves a fader (18). A motor driver (22) drives the motor (20). A switch circuit (26) is connected to the voltage control terminal of the motor driver (22). The switch circuit (26) switching-operates so as to selectively supply a control voltage in a plurality of stages to the motor driver (22). A fader CPU (14) controls the motor driver (22) and the switch circuit (26). The fader CPU (14) controls the switch circuit (26) to change a control voltage supplied to the motor driver (22) in stages. An integration circuit is provided between the motor driver (22) and the switch circuit (26). Accordingly, the circuit configuration of fader device is simplified.
