Abstract: A stationary member is fixed to a microscope. A movable member holds a sample and can move in a direction perpendicular to an optical axis of the microscope. A stepping motor moves the movable member. A rotation of the stepping motor is transmitted to the movable member by a power transmitter. An origin detector detects the movable member being positioned in an origin. A control unit controls the position of the movable member based on a signal from the origin detector and the number of driving pulses of the stepping motor. A power transmitter includes a reducer having a spur gear which reduces a speed of the rotation of the stepping motor, and an urging unit which applies a rotation force to the spur gear in one direction in a movement range of the movable member.

Abstract: In an image forming apparatus having single-color mode and full-color mode, to maintain an excellent fusing property of the single-color image and the full-image even on the condition that the temperature of the fixing member is easy to fall, when the temperature of the fusing roller lowers during the image forming job, the control for decreasing the subsequent image productivity or the control for discontinuing the job is performed within general performance power supply with ease. The reference temperature for determining such lowering of the image productivity or discontinuation of the job is set to be lower in the single-color mode than the full-color mode. As a result, both of the fusing property and the high image productivity can be realized.
