PURPOSE:To hold the precision of a product uniform by forming one optical element array with plural optical element blocks which are connected in its arrangement direction. CONSTITUTION:A plastic lens array 2 and a plastic roof mirror array 3 are arranged with a light shielding plate 4, which intercepts lights from individual adjacent lens elements and condenses a luminous flux, between them in a housing 1. In the front of the lens array 2, a right-angled plane mirror 5 for dividing an optical path is held by a holder 6 attached to the housing 1. Cover glasses 7 and 8 are provided in apertures between the housing 1 and the holder 6 above and under the right-angled mirror 5 respectively, and a light shielding paper 9 is provided in the apex part of the right-angled mirror 5, and an aperture stop 10 is provided in front of the lens array 2, and the light from an object 11 is reflected on the upper reflective face of the right-angled mirror 5 and is reflected to the roof mirror array 3 through the lens array 2 and is reflected on the lower reflective face of the right-angled mirror 5 through the lens array 2 again and passes through the cover glass 8 to form an unmagnification erect actual image 12 on an image surface.
