Title: Camera having bimorph driving element
Inventor: TANAKA YOSHIHIRO
IPC: G02B7/08
Filed: 1987-05-12
Abstract: PURPOSE:To exactly control driving of a shutter and a photographic lens, by controlling an impressing means so that a prescribed voltage is impressed before a prescribed voltage is impressed to a bimorph driving element and it is driven. CONSTITUTION:When transistors Tr11, Tr12 and a transistor Tr18 are turned 'ON', a piezoelectric element B is grounded, and to a piezoelectric element A, a voltage of 200V is impressed through a resistance Ra and the transistor Tr12, and a bimorph driving element Bi1 is bent as time elapses. In this state, when a prescribed exposure amount is obtained before an impressed voltage to the bimorph driving element Bi1 reaches 200V, a shutter is closed by short- circuiting both ends of the bimorph driving element Bi1 by turning 'OFF' both the transistors Tr11, Tr12, and thereafter, turning 'ON' a transistor Tr17.
