Abstract: A pickup device driving apparatus includes: a movable part which moves a pickup device in a first direction while a direction of a pickup surface is held; a linear actuator which moves an axis in a second direction different from the first direction; a direction changing part which has a bearing part provided in a third direction perpendicular to the first direction and the second direction, rotates on the bearing part, and changes a bias force applied in the second direction by the axis of the linear actuator to a bias force applied in the first direction, and applies the bias force to the movable part; and a weight part which is provided in the direction changing part to cancel a rotation moment of the bearing part generated in the direction changing part by the inclination of the movable part.

Abstract: An image pickup device driving apparatus includes: an image pickup device holder that holds an image pickup device, with an image pickup surface of the image pickup device directing to a predetermined direction, and is movable in a direction of optical axis; a movable unit that is provided to contact the image pickup device holder; a driving unit that moves the image pickup device held by the image pickup device holder in the direction of optical axis by driving the movable unit, with a surface direction of the image pickup surface unchanged; and a position holding power providing member that provides position holding power to hold a position of the image pickup device holder in the direction of the optical axis, and an imaging apparatus using the same.

Abstract: A pickup device driving apparatus includes a base of which the position is fixed with respect to a lens part, a movable part, a pickup device which is attached to the movable part in a state that a pickup surface is perpendicular to an optical axial direction, a first support part and a second support part which support the movable part, a first rotating part, a second rotating part, a third rotating part, and a fourth rotating part, and a driving part for driving the pickup device such that the position of the pickup device is changed relative to the lens part in a state that rotating center axes form vertexes of a parallelogram.

Abstract: A magnetic recording/reproducing apparatus is proposed wherein a hook arm is pivoted by a free end of one of two pivot arms when the pivot arms are urged by an inserted cassette and are pivoted by a predetermined angular interval, and the hook arm is disengaged from one of the link arms causing the cassette holders to descend when the hook arm is pivoted by a predetermined angular interval, thereby setting the cassette in the recording/play mode. The descent timing of the cassette is predetermined, and the cassette can be stably set in the correct recording/reproduction position.

Abstract: An improved apparatus is disclosed, by which two individually transversely cut web pieces, successively supplied from two different sources, are each attracted by suction onto the surface of either of a pair of suction rolls disposed parallel and rotated in opposing directions, at a first point of rotation of the rolls, and carried from said first point to a point at which the two rolls are in mating relation; at this mating point of rolls, the two cut web pieces each carried by either roll are put together or overlapped and carried by the other roll to a further point of rotation of said other roll, lower to the rolls, at which they are peeled off the roll surface and folded double by either of a pair of folding bars individually operatively associated with either roll, whereby the successively supplied cut webs are folded double in an intermeshing manner and piled below the rolls.
