Title:
FILM UNIT WITH LENS
Document Type and Number:
Japanese Patent JP2002333657
Kind Code:
A
Abstract:
To realize excellent daylight synchronous photography by a film unit with lens having a strobe light control function.
The base side of a light control stopping transistor 57 is connected to the collector side of a secondary transistor 46 conducted when a large aperture is set. Since the transistor 46 is not conducted when a small aperture is set, the transistor 57 gets in a shut-off state. Since a phototransistor 27 does not detect the reflected light of strobe light when the transistor 57 is shut off, a strobe light control circuit 55 is not actuated and a stroboscope fully emits the light.
