Abstract
An incremental positioner is disclosed. In one embodiment, the incremental positioner includes a motor, a drive shaft, a motion converter and a rack. The motion converter engages the rack and, impelled by the motor and drive shaft, causes the rack to move. The motion converter transmits and converts the continuous rotary motion of the motor to a linear intermittent motion of the rack. To generate such intermittent motion, the motion converter is physically configured so that even though the motion converter is in constant motion, it urges the rack to move on a periodic basis. In other words, during each revolution of the motion converter, the rack "dwells" (i.e., does not move) during a first portion of the cycle, and advances during a second portion of the cycle. Each time the rack advances, it does so by a characteristic incremental distance.
