Abstract

An image pickup apparatus which makes the load applied to a movable unit when it is displaced nearly uniform. The movable unit controlled by a control unit is capable of being in at least a predetermined direction. A first flexible board has a first connecting portion connected to the movable unit, a first wiring portion extended from the first connecting portion in a first direction different from a direction of an optical axis, and a second connecting portion placed at an end of the first wiring portion and connected to the control unit. A second flexible board has a third connecting portion connected to the movable unit, a second wiring portion extended from the third connecting portion in a second direction different from the direction of the optical axis, and a fourth connecting portion placed at an end of the second wiring portion and connected to the control unit.

Dependent claims

An image pickup apparatus comprising:

an image pickup device configured to convert an optical image of a subject into an electric signal;
a movable unit configured to hold the image pickup device and to be capable of being displaced in a direction different from a direction of an optical axis of an image pickup optical system;
a control unit including a circuit to which an image pickup signal output from the image pickup device is transmitted;
a first flexible board configured to electrically connect the movable unit and the control unit with each other;
and
a second flexible board configured to electrically connect the movable unit and the control unit with each other,
wherein the first flexible board comprises a first connecting portion that is connected to the movable unit, a first wiring portion that is extended from the first connecting portion in a first direction different from the direction of the optical axis, and a second connecting portion that is placed at an end of the first wiring portion and connected to the control unit,
wherein the second flexible board comprises a third connecting portion that is connected to the movable unit, a second wiring portion that is extended from the third connecting portion in a second direction different from the direction of the optical axis and opposite to the first direction, and a fourth connecting portion that is placed at an end of the second wiring portion and connected to the control unit,
wherein the control unit comprises a first cut formed at an edge of the control unit in the first direction and a second cut formed at an edge of the control unit in the second direction,
wherein the first wiring portion of the first flexible board is routed through the first cut,
wherein the second wiring portion of the second flexible board is routed through the second cut, and
wherein, in a case where the movable unit is displaced to a maximum extent possible, the first wiring portion of the first flexible board does not contact the first cut, and the second wiring portion of the second flexible board does not contact the second cut.
