Abstract

PURPOSE: To prevent wasteful photographing through inadvertent depression of release button to be accomplished with a simple constitution by detaining the release button which is slidable only in the vertical directions by means of a release ring which turns about its circumference.
CONSTITUTION: When a release button 2 which is slidable only in the vertical directions as it is prevented from turning by the leg part 2d fitted into the hole 1c of a housing 1 is depressed, its protrusion 2a causes contact springs 5, 6 to make contact, thereby letting measurement, etc. be accomplished. Further when the button 2 is depressed, the spring 6 and contact spring 7 make contact to actuate an electromagnet, then photographic is accomplished by required shutter operation. When a release lock ring 3 is turned along the outside circumference of the button 2 by way of a knob 3c, a lock plate 4 turns integrally causing a click spring 4d to fit into the click groove L' of the housing 1. At the same time, the end part of the groove 4c of the lock plate 4 hits against the leg 2c of the button 2, thereby preventing descending of the button 2 by the lock plate 4.
