ABSTRACT:
A device for slowly and smoothly displacing the display unit of a terminal such as a computer work station has a base and a platform movably supported on the base. The platform supports the display terminal and is oscillated back and forth along a path by a linear actuator disposed in the base. A shaft is mounted for rotation on a longitudinal axis and has a groove along the length of its outer surface helically inclined at an angle to the longitudinal axis. A motor rotates the shaft and a follower rides in the groove on the shaft and is connected for transmitting linear motion to the platform as the shaft rotates. The groove includes bidirectional helices joined at the ends by a circumferential groove section. The motor can be a synchronous motor with a gear arrangement providing an output which is laterally and downwardly displaced relative to the motor, whereby the shaft is compactly located immediately adjacent the base of the device providing the device with a low profile capability.
