PURPOSE:To exactly read information by making a lens system correspond to the changes of the reading location of a chromic film and a general original by moving the system and changing a focal distance and a size reduction factor, when the reading of the thermochromic film and the general original is performed. CONSTITUTION:This reader is provided with a heating part 13 winding up a chromic film 10 in a feeding part 11 and a winding up part 12 and performing a recording and an erasure for the film 10, a platen roller 14 holding the film 10, a film carrier roller 15, a roller 16 carrying general original 17 composed of paper, etc., and a driven roller 18. Further, an image reading location A is provided with a light source 20 irradiating the film 10 and the original 17 with light, a contact glass 21 located in an original carrier route, an pressure plate 22 opposed to this, a reflection mirror 23 deflecting reflected light in the direction of a reading part 24, an imaging device 25 and an image forming lens 26 composing the reading part 24, and the output from here is made to input in an image processing part 27. By doing in this way, the focus and size reduction factor in a film reading location A1 and an original reading location A2 are made to the same state. |
