PURPOSE:To simplify the constitution of a motor driving device and to reduce the power consumption of circuits by performing all of the position driving of an electronic flash,the driving of a photographic lens, and the opening/closing driving of a shutter through the rotation of one motor. CONSTITUTION:When the pulse motor rotates and a rotary driving plate 27 rotates counterclockwise from its initial position, an engagement projection part 31 pushes the engagement part 58b of an electronic flash unlock lever 58. Then, a lever 58 rotates clockwise and an electronic flash lock lever 56 rotates counterwise to unlock a recessed part 51a from a lock piece 56a. Then, an electronic flash body is raised upright and made ready for electronic flash photography. Then, the driving plate 27 rotates clockwise and a focus ring 18 rotates counterclockwise to extend a lens frame 19. Then when the driving plate 27 rotates counterclockwise toward the initial position, a driving pin 29 rotates a selector lever 33 counterclockwise and a shutter blade 1e is driven to open an aperture 1b. |
