A vibration wave driven apparatus includes a vibrator configured to generate vibration, a rotor configured to be in frictional contact with the vibrator and to rotate about an axis of rotation, and a transmitting member configured to rotate about the axis and to transmit rotation of the rotor to an external component. A part of the transmitting member forms a worm portion of a worm gear.

Vibration wave driven apparatus and image pickup apparatus including vibration wave driven apparatus

A recording apparatus for recording input information via a memory and a head onto a disc rotated by a disc driver, including a mode switch which successively provides a first mode direction for waiting for the recording and a second mode direction for performing the recording. A control circuit controls the apparatus in such a manner as to place only the memory in a wait state in accordance with the first mode direction, and then stores said input information into the memory in accordance with the second mode direction, at the same time or afterwards, starts the disc driver means.

Recording apparatus including plural storage means having standby modes

There is provided an optical device which comprises a fixed barrel, a movable cam ring, and collars and abutments. The movable cam ring is shifted relative to the fixed barrel to move an optical unit, the movable cam ring being fitted to the fixed barrel. Collars and abutments can be engaged with each other when the movable cam ring is in a predetermined positional relationship with respect to the fixed barrel. The collars and abutments preventing the movable cam ring from being disengaged from the fixed barrel and displaced in a direction along an optical axis relative to the fixed barrel.

Optical device

An image taking apparatus performs drive control to allow a zoom lens for magnifying an object image to stop at a stop position from both a telephoto direction and a wide-angle direction when a first mode and a second mode can be selected, and the first mode is selected, and performs drive control to allow the zoom lens to stop at the stop position from only one of the telephoto direction and the wide-angle direction when the second mode is selected.

Image taking apparatus, control method therefor, and control program

Impact absorbent shifting device

An apparatus, such as an image pickup apparatus, includes a first optical unit constituting part of an optical system, a first motor which drives the first optical unit, a second optical unit disposed behind the first optical unit and constituting part of the optical system, a second motor which drives the second optical unit, and a control device which controls the first motor and the second motor in such a way as to draw in the second optical unit in response to an instruction for stowing the optical system and draw the first optical unit into a space made vacant by drawing in the second optical unit. Thus, the control device controls the first motor in such a way as to draw the first optical unit into the space after the space is made vacant by drawing in the second optical unit.

Optical apparatus

An apparatus, such as an image pickup apparatus, includes an optical unit, and an operating device which brings the optical unit to a usage start position by drawing in the optical unit after drawing out the optical unit from a stowage position. The operating device causes a focal-length varying operation to be performed by further drawing in the optical unit from the usage start position.
