Abstract:
1. A solid state scanning type optical recording device comprising: optical shutter elements having an electro-optic effect; and a driver for dividing one line into a plurality of sections in the subscan direction and modulating the ON time of said optical shutter elements based on the image data of each section by a predetermined number of bits fewer than the number of bits of the image data, and driving said optical shutter elements at a gradient exceeding a maximum gradient corresponding to the predetermined number of bits; wherein the driver includes a shift register for forwarding image data synchronously with a shift clock; a latch register for latching image data of one section within said shift register in response to a strobe signal; a counter for counting standard clock signals; and a comparator for turning ON each optical shutter element, comparing the value latched in the latch register with the count value of the counter, and turning OFF each optical shutter element when both values match.
