Title:
PARALLAX ADJUSTING MECHANISM FOR FINDER
Document Type and Number:
Japanese Patent JPH0224641
Kind Code:
A
Abstract:

PURPOSE: To excellently adjust the parallax of a finder which often occurs at the time of macro-photographing by utilizing a movable reflecting member for switching an eye level and a waist level.

CONSTITUTION: In the case of performing observation at a waist level, a switching means 10 is operated in a direction shown by an arrow Q so that a holder 9 turns clockwise centering around a supporting shaft 9a and abuts on a stopper 12b to be held by a clipper spring 11. At such a time, a finder system at the waist level can be formed by an optical path combining points A-C in the optical path and a finder image can be observed through an eyepiece lens 3. Next, when a switching operation member 12 is operated in a direction shown by an arrow R in order to switch to a macro-photographing mode, the member 12 is held on a position where a flat spring 14 for clipping is plunged into a V-shaped groove 12C. Therefore, the stopper 12b moves upward and a reflecting member 8 finely turns cunterclockwise centering around the supporting shaft 9a, whereas an object positioned downward can be observed by an eyepiece lens 3.
