Abstract: A display device includes a pair of display units each including displays 1R and 1L and ocular optical systems 2R and 2L. A first driving unit can change an optical positional relationship between the displays 1R and 1L and the ocular optical systems 2R and 2L. A second driving unit can change an interval between the pair of display units. An interpupillary distance adjustment unit adjusts the interval between the display units by the second driving unit in accordance with a detection result obtained by the interpupillary distance detector. After interpupillary distance adjustment is performed, a diopter adjustment unit performs diopter adjustment related to the display unit by the first driving unit.

Abstract: A vibration wave motor includes a vibrating plate having a rectangular surface; a piezoelectric device bonded to the vibrating plate, and configured to vibrate at high frequency; and a projection provided on the vibrating plate or the piezoelectric device. In the vibration wave motor, a natural vibration mode, which has a resonant frequency equal to or adjacent to a resonant frequency of torsional vibration in a natural vibration mode under a state in which the vibrating plate, the piezoelectric device, and the projection are integrated, is a natural vibration mode of bending vibration in a direction parallel to or orthogonal to a torsion center axis of the torsional vibration in the natural vibration mode. The projection is provided at a position closer to an antinode than to a node, which are in the direction orthogonal to the torsion center axis of the torsional vibration in the natural vibration mode.

Abstract: A vibration wave motor includes a vibrator, a friction member having a sliding surface, a guide member, a flexible substrate, and a fixing member configured to fix the friction member, the guide member, and the flexible substrate. The vibrator and the friction member move relative to each other in a predetermined direction. The fixing member includes a substrate-fixing portion configured to fix the flexible substrate, which includes a joint portion, an extending portion extending along the predetermined direction, a bent portion configured to reverse and turn back the extending portion, and a fixed portion to be fixed to the substrate-fixing portion. The flexible substrate is fixed on a surface of the substrate-fixing portion provided in a direction opposite to a direction in which the vibrator is brought into pressure-contact with the friction member.
