Title:
FILM UNIT WITH LENS
Document Type and Number:
Japanese Patent JP3850008
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To naturally imprint even a background indoors or at night and to enable any person to perform daylight synchro photographing without failing.
SOLUTION: When a photographing mode switching knob 10 is set to an index 'outdoors', a small diaphragm aperture 35a is inserted in a photographing optical path and the value of a photographing diaphragm becomes F13. A stroboscope charging button 9 is optionally pressed in this outdoors photographing mode. By pressing the button 9, a switch armature 40 is pressed by the button 9 and elastically deformed, so that the edge part of the armature 40 makes a pair of print pattern contacts 41 short-circuit to start the charging a stroboscopic circuit. When the knob 10 is set to an index 'indoors', a diaphragm switching plate 35 is retreated from the photographing optical path and the photographic diaphragm of a photographing lens 5 becomes an open aperture F5.6. Simultaneously, the end 35b of the plate 35 is inserted between the button 9 and the armature 40, and the armature 40 is pressed by the end 35b of the plate 35 and elastically deformed, so that the contact 41 is kept in a short- circuited state and a stroboscopic unit 23 is made to always emit light.
