Abstract
PURPOSE: To reduce the mulfunction and to simplify the operation panel, by using one selection switch 1 attached to each of function mode.
CONSTITUTION: When the transparent image observing mode is selected 5, only the counter 2a corresponding is waited and the pulses caused are counted with the operation of the adjusting switch 1, and the reference voltage is selected by reading out the count of the counter 2a based on the code signal 5 at the decoder 3, and the lens 7 is fed for the power by selectively driven the relay R so that the voltage is fed to the exciting circuit 8. According to the increase in the count value, the switch 1 is rotated left and right so that high magnification can be obtained and adjustment is made. It is similar in selecting the mode of the limited sight image observation and the diffractive camera, the up and down counter corresponding is waited and the magnification and the camera length can be adjusted with the rotation of the switch. The counter 2d in waiting performs amplitude selection 4 based on the code signal 5, power is fed to the deflection coil 9 and the amplitude is reduced in step depending on the increase in count value. Thus, the operation can be simplified by only the switch 1.
