Abstract

PURPOSE:To realize an original fixation type copying machine using an inexpensive plane lens array by forming an imaging optical system between an original surface and a photoreceptor drum surface by using lens array plates and a mirror. CONSTITUTION:On an axial line A-A parallel to the contact glass 7 of a copying machine, the 1st mirror 11 composed of a plane mirror having length equivalent to the width of an effective copying area is arranged at a prescribed angle to the contact glass surface and scans on the axial line A-A parallel to the contact glass surface at a speed V in a direction B. Further, the 2nd mirror 12 composed of a plane mirror to receive a optical beam reflected down obliquely by the 1st mirror 11 is arranged on an axial line C-C and move in a direction D so as to reduce a speed component in the direction A-A to 3/4V. Consequently, a low-cost copying machine with said constitution is realized.
