Summary: | PURPOSE:To prevent the variation of the density of displaying pictures so as to obtain stable pictures, by constituting an electric current detecting area so that a practically similar environmental condition to a photosensitive body in a picture area can be set always. CONSTITUTION:An incident light window 31 is provided at a section correspond ing to the stopping position when a solidly written area 30 is constituted so that the area 30 can be stopped the outside of a display section. Therefore, the writing area 30 can be maintained under an external light incoming condi tion with is practically similar to a picture area even if a belt is stopped and the density variation of displaying pictures can be prevented further effectively. Accordingly, a stable picture display device can be obtained. |
