Problems solved by technology

[0005] However, in the drive device described in Patent Document 1, each piezoelectric motor is driven by a separate drive circuit, so the same number of drive circuits as the piezoelectric motors is required.
Therefore, there is a technical problem that it is difficult to further reduce the size, weight and cost of the driving device.

Abstract

A drive device includes plural moving portions, piezoelectric motors that move the moving portions, at least one drive circuit that drives the piezoelectric motors, and a connection / disconnection portion that connects and disconnects the piezoelectric motors and the drive circuit. The number of drive circuits is fewer than the number of piezoelectric motors.

Description

technical field [0001] The present invention relates to a driving device, an electronic component conveying device, an electronic component inspection device, a manipulator, and a robot. Background technique [0002] There is known a drive device that drives a plurality of motors by a single drive circuit to move a movable part. Such a drive device is used as a positioning device, for example, and can position the movable part at a predetermined position by sequentially driving a plurality of motors that move the movable part in different directions by a drive circuit. Conventional positioning devices generally use electromagnetic motors and pulse motors, but it is necessary to provide a braking mechanism for each motor to keep the rotor in a non-driving state from rotating. [0003] In response to this, a drive device using a piezoelectric motor (piezoelectric actuator) has been proposed (for example, refer to Patent Document 1). Since the piezoelectric motor transmits th...
