PROBLEM TO BE SOLVED: To eliminate the need for controlling the movements of a reader and that of a shielding member separately when the reader and the shielding member are moved without interference.SOLUTION: A second movement mechanism 82 is provided. The second movement mechanism 82 converts a rotation force transmitted from a gear 54 that rotates in one direction (in a counterclockwise direction in Fig. 7) into a movement force in a moving direction of an image sensor 42, transmits the converted movement force to the image sensor 42, and moves the image sensor 42 to a reading position from a first separation position after the first movement mechanism 81 moves a shielding member 44 to an opening position. |
