PURPOSE:To make a whole camera small in scale, light in weight and to save energy by making a first and a second supporting bodies cylindrical sheet springs and arranging them in parallel with each other in a direction perpendicular to an optical axis. CONSTITUTION:The first supporting body 7 and a second supporting body 8 are linked with an inner frame 13 and an outer frame 14 and a holder 5 is attached in order to project from a first supporting body 7, then a solid state pickup element 11 fixed on the holder 5 is finely vibrated in a direction T parallel with the optical axis. Driving force caused by an outer yoke 9, a magnet 10, a center yoke 12 and a voice coil 6 is utilized as the driving system. The first and the second supporting bodies are cylindrical sheet metallic springs and they are able to move only in the one axis of T direction. By arranging and linking the first and the second supporting bodies 7 and 8 in parallel with each other in the direction perpendicular to the T direction which is a movable direction, axial fluctuation at moving time can be removed. Moreover, power consumption can be made smaller since a magnetic circuit consisting of the voice coil 6 and the magnet 10 is used as the driving system. |
