Title: Cancel mechanism for turn-signal switch
Inventor: NISHIO MINORU
IPC: B60Q1/42
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To fix a rotation angle of a cancel cam until a ratchet becomes a standby state for a cancel operation, and prevent noise. SOLUTION: In this switch, with rotation of a cancel cam 1, a tip portion of an abutting projection 27 gets up on a cam surface of a tangent cam part 4, and pushed back against a energizing force of a ratchet spring. Thus, a pressing force acting between a ratchet 26 and the tangent cam part 4 is gradually increased, and a friction force between them is gradually increased to suppress a slip between them. At that time, a clockwise rotation moment acting around a guide pin 29 of the ratchet 26 becomes larger than a friction force between the cam surface of the tangent cam part 4 and the tip portion of the abutting projection 27, so that the ratchet 26 always rocks in the clockwise direction about the guide pin 29.

At the time of a power failure, the power source of the crime prevention camera 11 is switched from the main power source circuit 2 to the auxiliary power source 3 by making use of a power source switching circuit 13. At the same time, the emergency photographing mode (for example, five frames per second) of the crime prevention camera 11 is switched to an EF photographing mode (for example two frames per second) in response to the chargeable time of the EF 12 by making use of the photographing interval control circuit 15. Thus photographing at the time of the power failure is made possible and the satisfactory photographing result is obtained in any condition.
