PROBLEM TO BE SOLVED: To provide an image-changeable driving module which is equipped with a driving part using a spring as a power source and constituted by combining the driving part and a clamp lever connected through a gear train to swing with each other in one body. SOLUTION: The driving module, equipped with the driving part using the spring as the power source and constituted by combining the driving part and the clamp lever which is connected through the gear train to swing with each other in one body, is so constituted that an image printed on the surface of an image-changeable card changes as the angle of a line of sight to the image- changeable card supported by the clamp lever varies through the swinging of the clamp lever; and a lenticular print or holography print is given on the image-changeable card.
