<P>PROBLEM TO BE SOLVED: To provide a lens drive device capable of reducing the number of switches by having a constant speed control function which can store and reproduce a zoom speed during constant speed control as a preset speed, and using a switch used for a position preset function also for the constant speed control function. <P>SOLUTION: A lens drive device having a constant speed auto zoom function and a position preset function, stores a zoom position when an ON switch 30 and a memory switch 32 are pushed, as a preset position of the position preset function, moves the zoom position to the preset position by the position preset function when only the ON switch 30 is pushed. The device stores a moving speed of the zoom position when the ON switch 30 and the memory switch 32 are pushed while operating a seesaw switch 20, as a preset speed of the constant speed auto zoom function, and moves the zoom position at the constant preset speed in a moving direction of the seesaw switch 20 when only the ON switch 30 is pushed while operating the seesaw switch 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
