Abstract

PURPOSE:To overwrite with a laser beam printer which is cheap requiring no memory, by forming the device by providing a laser light source of two arraylike elements and the mirror having a slit-form hole. CONSTITUTION:The light emitted from laser light source 1 where two elements 1 and (b) are formed on the same wafer and are capable of driven independently is collimated to branch in different directions, and one beam passes through the slit of mirror 5 and is focused onto photosensitive drum 7. The other beam is reflected by mirror 5 and is focused onto original 6 where the form is written. This focused spot is oscillated continuously in a fixed light quantity; and if the surface of original 6 is scanned by this signal and original 6 is moved in the arrow F direction, the reflection or permeation light quantity is different by the variable density of the original, and it is received by photodetector 8 to form an original signal. The position of detector 8 is changed according to the reflective or transmissive original. Thus, picture overwriting is obtained which requiring no memory and is independent of the negative and the positive of the original.
