Abstract

PURPOSE: To prevent the danger for the photographer owing to over-water pressure and the failure of the camera owing to excessive water pressure by displaying water pressure by the signal of the measuring part which maintains water-tightness and receives water pressure.
CONSTITUTION: A water pressure measuring part 2 and water pressure display part 3 are provided to the camera body 1. The measuring part 2 consists of a flexible pressure sensing membrane 6, axially movable connecting rod 7, an oscillating lever 8 which is oscillatable by the movement of a drive pin 7a, etc. Further the contact 8c of the lever 8, conductive patterns 9aW9d, display marks 3aW3d are connected to an electric power source 11 by way of terminal 3e respectively. When with this constitution the sensing membrane 6 is pressed by the specified water pressure, the rod 7 moves by a fixed amount and the oscillating lever 8 turns clockwise. When the contacts 8c and conductive pattern 9a contact electrically, "1" corresponding to the specified pressure is emission-displayed in the 1st display mark 3a, by which the water pressure may be recognized.
