Title: Stroboscope attaching structure for camera
Inventor: HISHINUMA KOJI
IPC: G03B15/05
Filed: 1989-12-25
Abstract: PURPOSE:To obtain sufficient emission light quantity which is appropriate for long- distance photographing and short-distance photographing at the narrow irradiation angle of emission light by using a small-capacity capacitor by supporting a stroboscope in a camera main body so that it can be freely rocked with respect to a photographing lens part by interlocking with the focusing ring of the photographing lens part. CONSTITUTION:When the focusing ring 17 rotates in an approaching direction, the stroboscope 13 is made to rock to the photographing lens barrel 12 side centering around a shaft 14 by a cam follower 16 and a cam 18, and when the focusing ring 17 rotates in a long-distance photographing direction, the stroboscope 13 is made to rock in an opposite direction to the photographing lens barrel 12 centering around the shaft 14 by the cam follower 16 and the cam 18. Since the stroboscope 13 is made to rock from right to left by interlocking with the focusing ring 17, both of short- distance photographing and long-distance photographing can be covered at the narrower irradiation angle than that of the emission light in the case of long-distance photographing as usual, the stroboscope 13 is miniaturized, and the sufficient emission light quantity which is appropriate photographing circumstances is obtained even by using the small-capacity capacitor.
