Title: Reflection preventive film
Inventor: TERADA JUNJI
IPC: G02B1/11
Filed: 1988-01-26
Abstract: PURPOSE:To realize the reflection preventive film which has high transmissivity and provides excellent heat generation as a cloud-preventive film by specifying the film thickness of the transparent conductive film of the reflection preventive film including the transparent conductive film. CONSTITUTION:The reflection preventive film consists of films 1-3 provided on an optical element 4, and one layer among the films is the transparent conductive film 3, whose film thickness is 45-120nm. Thus, the conductive film 3 among the reflection preventive films 1, 2, and 3 is formed to <=120nm thickness, so the light absorption by the transparent conductive film 3 is reduced to obtain sufficient transmissivity which is used for the optical element 4. Further, the film thickness range is set to 45-120nm, and consequently the surface resistance is smaller than before and suitable for the heat generation of the optical element 4 such as an optical lens, thereby realizing the reflection preventive films 1-3 including the transparent conductive film 3 which is used excellently as the cloud preventive film.

Abstract: PURPOSE:To form an image of high quality of high quality even when a trimming and a masking area are copied with variable power by controlling the exposure range of an electrostatic discharging device according to the variable power rate when a specific area of an original is copied with the variable magnification. CONSTITUTION:When the original is copied with the variable power while part of it is trimmed or masked, position coordinate data on the target area 3, i.e. X110.5 is inputted to a control circuit 21 by using a ten-key 6 and function keys 7 and data X2, Y1 and Y2, e.g. a reduction rate of x0.65 is inputted similarly. Then, the control circuit 21 calculates the exposure range by using those coordinate data and variable power rate and drives and controls an LED for electrostatic discharging on the basis of the signal. For example, when a reduced copy is taken, the turn-off width is made narrower than in life-size copying operation. Consequently, an image of high quality is formed even when a trimming and a masking area are copied with variable power.
