Abstract
A control device suitable for use in a sing-along or karaoke apparatus has a rotary encoder coupled to a selector knob through a transfer mechanism, such as gears. When the selector knob rotates, the rotary encoder generates pulse signals for each rotation of the selector knob. The number of pulses may depend upon a gear ratio of the transfer mechanism. The control device is used, for example, to scan and select music titles stored in a ROM cartridge or other suitable storage medium. The control device may be integrated with an apparatus for controlling the start or stop function. The control device provides a design flexibility due to its compact design.
