摘要： A driving mechanism includes a first piezoelectric element and a first driving member that is driven by the first piezoelectric element and that vibrates in a first direction. The first driving member includes a second piezoelectric element and a second driving member that is driven by the second piezoelectric element and that vibrates in a second direction different from the first direction. A difference between the vibration resonance frequency of the first driving member and the vibration resonance frequency of the second driving member is equal to or less than the half-width at a half maximum of a function representing an amplitude frequency characteristic in the vibration of the first driving member.

摘要： A driving apparatus of the present invention comprises: a lead screw which rotationally drives; and a follower section to hold a driven member L and to rectilinearly move based on rotation of the lead screw. The follower section comprises a first tooth and a second tooth that faced a side portion of the lead screw and are opposite to each other and a third tooth provided in a position different from those of the first tooth and the second tooth. When the follower section rectilinearly moves based on the rotation of the lead screw, power is transferred with the lead screw and the first tooth being engaged with each other, and the lead screw is in a non-contact state with the second tooth and the third tooth.

摘要： A digital camera includes: a mirror box that defines a space in which a light flux from a photographic lens is guided to an imaging unit; a mirror unit that is arranged inside the mirror box and is configured to rotate between a viewing position in which the mirror unit is inserted in a photographic light path from the photographic lens to the imaging unit to reflect the light flux and a photographing position in which the mirror unit is retracted from the photographic light path; and an opening section that discharges from the mirror box air that is moved when the mirror unit is rotated.
