Title: Illumination for polarized bright and dark viewfield
Inventor: HAYASAKA TOSHIMI
IPC: G02B21/08
Filed: 1981-10-12
Abstract: PURPOSE:To protect the eyes of a microscope examiner, by providing a shutter which works in response to the changeover of optical paths. CONSTITUTION:An optical path switch knob 10 is kept pushed in the case of the illumination of a dark viewfield. The projected part 13a of a shutter 13 touches a flipping member 16 adhered to a lens barrel attachment frame 2 and is turned left around a shaft 14 fixed to an optical path switch frame 4 to be flipped out of the optical path. Here an optical path switching knob 10 is pulled out slightly as shown in figure. Thus the shutter 13 moves to the left side of the frame 4 and turns right by its empty weight. As a result, the shutter 13 hits a stopper 15 to cut off partially the optical path of illumination. The harmful light reflected on the sample surface and entering a viewfield is cut off by the shutter 13. The knob 10 is pulled out further to switch the illumination to a bright viewfield. In this case, the shutter 13 is kept at the position of the stopper 15 and cuts off a part of the optical path of illumination. However, the light of illumination is kept bright enough.

Abstract: PURPOSE:To execute an information output from an original with maximum efficiency by successively connecting a voltage generated at both edges of a resistance to the amplifying circuit of a high input impedance with an analog switch in a status that the resistance is connected in series to a photoelectric converting amplifying semiconductor element and a voltage is impressed. CONSTITUTION:A voltage/current characteristic up to a voltage V0 to be impressed to an element is measured by a linear scale, a straight line is drawn from the point of the voltage V0 and a current 0 and a voltage V1 of a point where this straight line crosses the characteristic curve of a dark status and a curve V2 of a point where this line crosses the characteristic curve of a bright status are obtained. The straight line is determined so that V1-V2 can go to be maximum and by the inverse number of the gradient of the straight line, a resistance value is obtained. Thus the determined resistance is connected to the respective elements of an image sensor, a voltage to be generated in both edges is selected by an analog multiplexer and since the voltage is connected to the buffer of a high input impedance, a reflecting light from an original is converted to an electric information signal. Thus, a reading speed for one line can be increased adequately.
