PURPOSE:To obtain the inexpensive polarizing element which absorbs no light by providing a means which separates incident luminous flux into two linear light components, converges the components on different positions, and rotates the plane of polarization of one obtained linear polarized component. CONSTITUTION:A double reflection layer 102 made of an optically anisotropic material separates the ...

PURPOSE:To prevent motor noises at the time of driving a rotary filter from reaching the side of a control circuit by separating a power source for driving the rotary filter and a power source for control from each other. CONSTITUTION:The rotary filter 22 which transmits light beams of the primary colors for a surface sequential type scope is rotated by a motor 21 and also put on and off the optic...

An electrophotographic apparatus having: a developer unit that has a magnetic developing roller for applying toner to electrostatic latent image areas formed on the surface of a photoconductor and that has a shutter which is closed to regulate the distribution of the toner to the photoconductor, a developing bias voltage for controlling adherence of the toner to the photoconductor being applied to...
