    摘要: An optical unit is constructed by superposing and cementing the first substrate having fixed electrodes and the second substrate having a sheet-like member in which a moving plate-spring-like electrode is provided. Concentric through holes are provide at the middles of the sheet-like member of the first substrate and the second substrate, and an optical element, such as a lens, a mirror, or a prism, is mounted to the through hole of the sheet-like member. When voltages applied between the fixed electrodes and the moving electrode are controlled, the sheet-like member is displaced and thereby the optical element is deformed.

    摘要: A driving apparatus includes an electromechanical conversion element that expands and contracts through the application of a drive voltage, the electromechanical conversion element includes a first end and a second end. The apparatus further includes a support member that is fixed to the first end of the electromechanical conversion element in a direction of expansion or contraction of the electromechanical conversion element; a drive member that is fixed to the second end of the electromechanical conversion element in the direction of expansion or contraction; an engaging member that engages with the drive member with a friction force; and a drive circuit that drives the electromechanical conversion element. The drive circuit generates a rectangular waveform drive voltage and applies the rectangular waveform drive voltage to the electromechanical conversion element to cause the electromechanical conversion element to expand and contract at different speeds to thereby move the support member and the engaging member relative to each other.
