An unprocessed substrate is conveyed to a film-processing chamber at the same time a processed substrate is conveyed to a substrate preparation chamber, reducing the substrate processing cycle, thereby increasing the yield per unit time. The substrate preparation chamber has a two-tiered structure for receiving processed substrates and unprocessed substrates. A two-tiered transfer robot allows the substrates to be removed or placed into the preparation and process chambers at the same time, thus decreasing the cycle time for processing a substrate.

A printer controller,sets compensation values, representing the positional deviations of LED array chips,in a delay circuit section,via shift register,and a latch circuit,The shift register,sequentially acquires bit map data from the printer controller,and supplies the acquired bit map data to an AND gate,through the latch circuit,Upon receiving a strobe signal from the printer controller,the delay circuit section,supplies the received strobe signal to the AND gate,after a delay time corresponding to a preset compensation value has lapsed. The AND gate,generates drive signals each being the logical product of the input bit map data and the strobe signal, and supplies them to the LED array chips,through a buffer,The LED array chips,make LEDs emit light at the timings corresponding to the positional deviations so that images are formed without a positional deviation. At least one of the LED array chips is unaligned with adjacent ones of the LED array chips and preset compensation values are obtained by interpolation based on detected positional deviations of sampled ones of the LED array chips.

Optical writing head driving device

A photocopying apparatus is provided in which a moving area of a lens at the time of a magnification changing and that of an optical device such as a mirror unit overlap partly. At the time of the magnification changing, it is determined whether the optical device is positioned at a home position. When the optical device is not located at the home position, the lens is caused to move for the purpose of the magnification changing after the optical device is returned to the home position.

Photocopying apparatus

This invention relates to means of separating a copying paper from a sensitive body in an electronic copying machine, said means making it easy and sure to separate the former from the latter by controlling variably a voltage for removing electric charges by detecting variations of a differential current between the current flowing to an electrode of a charged device for copying, i.e. quantity of electric charges given to the copying paper and the current flowing to a shield case of the charged device.

Means for separating a copying paper from a sensitive body in an

A copying apparatus includes a copy paper-separating device which separates a copying paper from a rotary drum by engaging the projecting portion from the corresponding end face of the rotary drum by a prescribed width, and a detecting device for detecting whether the projecting portion of the copying paper has a prescribed width, before the copying paper reaches the rotary drum.
