  • Apparatus and method for sensing rotary switch handling direction of monitor
    Patent number: 6696984
    Abstract: An apparatus and method for sensing a rotary switch handling direction of a monitor is disclosed, in which a simple configuration can be obtained and accuracy in sensing a handling direction can be enhanced. The apparatus for sensing a rotary switch handling direction of a monitor includes a rotary switch for outputting voltage levels varied correspondingly depending on a user's handling direction, and a microcomputer for storing the voltage levels output from the rotary switch and comparing the voltage levels with a previously stored voltage change/handling direction table to determine a handling direction of the rotary switch. Since the handling direction is sensed by the voltage level difference for respective contacts, it is possible to exactly sense the handling direction and to relatively obtain a simple configuration.
