Abstract

A light-emitting-part holder moves between a housing position in which the light-emitting-part holder is housed in a housing part formed in a strobe base and a light emission position in which the light-emitting-part holder projects from the housing part. One end of an arm member is supported by the light-emitting-part holder, and the other end thereof is supported by the strobe base. An arm cover member holds a magnet, and in a case where the arm member is housed in the housing part, the arm cover member is fixed to the face of the arm member facing the housing part. A part of a light-emitting-part flexible board (flexible wire member) is disposed between the magnet held by the arm cover member and the arm member.

First claim

What is claimed is:

1. An image pickup apparatus that includes a light emission unit which holds a light emitting part and moves between a housing position at which the light emission unit is housed in a housing part formed in a base member and a light emission position at which the light emission unit projects from the housing part, the apparatus comprising:
an arm member, one end of which is pivotally supported by the light emission unit and the other end of which is pivotally supported by the base member;
a circuit board that is disposed inside the image pickup apparatus;
a flexible wire member that connects the light emitting part and the circuit board;
a holding member that holds a magnet and is fixed to the arm member;
a magnetism detection unit that is provided inside the image pickup apparatus and detects magnetism of the magnet; and
a control unit that controls light emission of the light emitting part based on an output of the magnetism detection unit,
wherein the holding member is fixed to a surface facing the housing part in a case where the arm member is housed in the housing part, and
wherein a part of the flexible wire member is disposed between the magnet held by the holding member and the arm member.

2. The image pickup apparatus according to claim 1 , wherein the magnetism detection unit is mounted on the circuit board,
wherein, in a case where the output of the magnetism detection unit is equal to or lower than a threshold value, the control unit causes the light emitting part to emit light, and
wherein, in a case where the output of the magnetism detection unit exceeds the threshold value, the control unit controls the light emitting part not to emit light.

3. The image pickup apparatus according to claim 1 , wherein the arm member is formed of a soft magnetic material, and
wherein the holding member and the housing part are formed of a synthetic resin material.
