Title: Real-image type finder optical system
Inventor: FUJISAKI YOSHIBUMI
IPC: G03B13/06
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a real-image type finder optical system with which a focus mark and a short-distance correction mark can be displayed, even though foreign matters such as dust will not be seen. SOLUTION: Luminous flux emitted from an objective optical system is converged near a prescribed image forming surface through a reflection mirror and a condenser lens, so as to form real image of an object. Then, a visual field frame 6 is arranged within the image forming surface. The frame 6 is obtained by forming a hollow window H and provided with the notched or a projecting focus mark F and a short-distance correction mark M formed at an edge side in the window H. Since foreign matters such as dust is unable to be positioned within the hollow surface of the window H, real image can be formed within the window H without causing turbulence. The luminous flux emitted from the frame 6 advances toward an eyepiece through a Porro prism. Thus, the marks F and M can be confirmed visually together with the object by a photographer.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an overload or overcurrent, when a strong reverse wind, etc., occurs by setting the setting value of a voltage limit level setting means, according to the output signal of a speed detecting means. SOLUTION: A voltage limit level setting means 6 outputs a setting value for setting the upper limits of the peak values of three-phase sine wave voltages O1, O2, and O3 which are the output voltages of a driving circuit 3 to a voltage limiter means 7 as an output signal V6. The output signal V6 is changed, in accordance with the output signal N5 of a speed detecting means 5, and when the signal N5 decreases (or increases), the signal V6 decreases (or increases). The means 7 limits the upper limits of the peak values of the voltages O1, O2, and O3, outputted from the driving circuit 3, by limiting the output signal V4 of an output voltage commanding means 4, based on the output signal V6 of the setting means 6.
