Abstract

PROBLEM TO BE SOLVED: To provide a switch mechanism and an image pick-up device having the same which can prevent an erroneous operation with a simple structure. SOLUTION: A tip of a projection member 4c is inserted in between an elastic member 4d when a switch main body 4a is slid in order to make the switch ON. At this time, the elastic member 4d is pressingly spread by the projection member 4c. An end of the switch main body 4a is moved along an inclined surface 4e to thereby push insert the switch main body 4a into a main body 1 when the switch main body 4a is slid and pressed, resulting in making the switch ON. On the other hand, the projection member 4c is pushed out by repulsive forces of an elastic member A4d and an elastic member B4f when a pressure applied on the switch main body 4a is stopped. Accordingly, the end of the switch main body 4a is conversely moved along the inclined surface 4e to thereby erect the switch main body 4a from the inside of the main body 1, leading to make the switch OFF.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch mechanism used for an image pickup device such as a video camera.

[0002]

2. Description of the Related Art A recording switch in an image pickup apparatus such as a video camera includes a slide switch. For example, in a slide type switch, a switch which is not an automatic restoration type may not notice even if the switch is in an ON state, and may waste tape and a battery. The automatic restoring type has to be held in a sliding state at the time of video recording, and thus has poor operability.

For this reason, a configuration is employed in which recording is turned ON / OFF by using a push-type switch that is turned ON only while the recording switch is being pressed. In such a push-type switch, the user may accidentally press the switch when carrying the device, and recording may be started without his knowledge.
