PURPOSE: To obtain an image recorder whose cost is drastically reduced by switching the different optical path of image light by simple structure with a small number of parts while keeping the positional accuracy of a mirror. CONSTITUTION: A 4th mirror 68 and a 5th mirror 70 are fixed in a sub frame 220 in a mirror unit 52, and the sub frame 220 is turnably supported on the main frame 224 by a supporting shaft 222. When the main frame 224 is moved and reaches a specified position, a switching projection presses and rotates the sub frame 220 so as to switch the 1st optical path X and the 2nd optical path Y. By such constitution, the high positional accuracy of the 4th and the 5th mirrors 68 and 70 is secured and the number of parts is drastically reduced, then the cost is made low. |
