Title: Picture projector
Inventor: TAKANASHI RYOYU
IPC: G09G3/36
Filed: 1990-06-22
Abstract: PURPOSE:To reduce noise and to achieve picture projection having a satisfactory contrast ratio by reading a picture while allowing the threshold of a light-light conversion element to correspond with the black level of a projected picture. CONSTITUTION:As for light-light conversion element 10 an appropriate original picture 24 is projected via an optical system 28 by the use of light outputted from a light source 26. The original picture 24 has the gradation characteristic in which the brightness of the black level is limited. In the light-light conversion element 10, the light transmissivity of an optical modulation layer 20 is changed according to the inputted optical picture. At this time, the total voltage applied to the optical modulation layer 20 is controlled in such a manner that the black level of the original picture 24 matches the threshold, thereby setting the black level of the original picture 24 to the lowest brightness level when it is read from the light-light conversion element 10. Thus, the contrast ratio of the projected picture is improved, and a photoelectric conversion signal having a satisfactory S/N can be obtained.

Title: Separating device of form
Inventor: KOUNO TADAAKI
IPC: G03G15/14
Filed: 1983-09-06
Abstract: PURPOSE:To place a separation pawl invariably in a cleaning state by putting the separation pawl slightly away from a separation position, and rotating the separation pawl to a cleaning position when the rear end of the form passes by a separation position. CONSTITUTION:A timer is set to the time when the form 2 is separated with the separation pawl 6 after a transfer process and the conveyed by a conveying device 16. The separation pawl 6, therefore, leaves the separation position immediately after starting the separating operation to prevent a toner on a photosensitive body 1 from being scraped off. Then when the rear end of the form 2 is detected by a detecting means S2 which detects the form after the separation, solenoids 11 and 110 are turned off until the next form 2 is detected by the detecting means S1. Consequently, the separation pawl 6 leaves the photosensitive body 1 by its own weight or energizing force of a spring and is rotated to the opposite side across its conveyance path B. A cleaning means 15 is arranged there to restrict the further rotation of the separation pawl 6, which is then cleaned up.
