Patent number: 6856426Abstract: An 8-bit (256 gradient) image is represented using a driver IC of 6-bit (64 gradient) construction to drive a plurality of arrayed optical shutter elements. The image data are divided into 64 gradient sections, synchronized by shift clock signals, and transmitted in four cycles to the shift register. The optical shutter element is not turned OFF at the 64th pulse, but is continuously driven without transmitting to the comparator the standard clock signal of the 64th pulse, which controls the ON time of the optical shutter element. In this way, an image of a higher number of gradient levels can be represented using a driver IC of a low number of bits, thereby providing a solid state scanning type optical recording device which suppresses noise generation by reducing the load on the driver IC when driving at multi-level gradient.Type: GrantFiled: November 16, 1999Date of Patent: February 15, 2005Assignee: Minolta Co., Ltd.Inventor: Yuta Miyagawa

Patent number: 6081321Abstract: Disclosed is a full color printer which comprises a optical writing head for writing a latent image onto a printing paper such as a silver salt-sensitive member. The optical writing head has an array of optical shutter elements each of which is made of PLZT. Red color light, green color light, and blue color light are sequentially projected to the light shutter element, and the drive voltage applied to the light shutter elements is changed synchronized with the color change. To prevent the generation of spike noise, the drive voltage is not changed suddenly, but is changed smoothly.Type: GrantFiled: May 26, 1998Date of Patent: June 27, 2000Assignee: Minolta Co., Ltd.Inventor: Yuta Miyagawa
