PURPOSE:To correct the extremely small shift between a projected image area of a film and a lighting area on a reader or reader printer by providing a simple position adjusting mechanism such as a screw and a cam. CONSTITUTION:A screw hole 24 is formed at the front lower part of a lighting unit 22, and a screw 21 suitable for it is screwed in until its tip abuts on the front part wall 2a of a lower machine box 2. Then, the screw 21 is turned, for example, counterclockwise to press the light unit 22 into the machine by distance l, and the optical axis (k) also moves by the disatance l to move a lighting area on a microfiche. The lighting system in the lighting unit 22, however, is arranged in one body, so the light area varies in neither area nor quantity of light. Therefore, even if the light area A shifts breadthwise from an area B of the film, the lighting area A is moved breadthwise to make the both coincident with each other. |
