PROBLEM TO BE SOLVED: To evaluate performance of an image reading position with high precision by grasping behavior of a movable member such as a reflection mirror by a survey. SOLUTION: A reading position evaluating system is provided with an image reading apparatus 1 which has a lamp 13 for irradiating an object to be photographed with light, reflection mirrors 15, 16, 17 moving according to movement of the lamp 13, and sequentially reflecting reflected light from the object to be photographed and an imaging device 10 for receiving reflected light from the reflection mirror 17 and imaging the object to be photographed. Further the system is provided with reflection tools 21A, 21B attached to the reflection mirror 16, a speed measuring apparatus 20 which irradiates the reflection tools 21A, 21B with light and receives the reflected light to measure moving speed of the reflection tools 21A, 21B when the reflection mirror 16 moves, an arithmetic processor which computes positions and inclinations of the reflection tools 21A, 21B from measuring result by the rate measuring apparatus 20 and predicts the image forming position of the reflected light from the reflection mirror 17 on the image pickup element 10, and a display apparatus for displaying prediction result.
