Abstract
PURPOSE: To obtain a moving coil device for camera in thin structure enabling to draw out the output shaft in an arbitrary direction, by constituting the coil in flat plate, and disposing the magnet and yoke in a way to sandwich the coil.
CONSTITUTION: A coil 10 is formed by gluing two flexible print coils 11 of the shape having conductors placed on the rectangular sides to a reinforcing plate 12, setting each central part face to face, and the upper and lower parts projecting from the reinforcing plate 12 are folded in plural layers. This coil 10 is placed between a permanent magnet 21 and a yoke 22. In this device, when power is supplied to the coil 10 through the lead wire of spring type, the coil 10 makes linear motions within the slidable range by oval hole in the reinforcing plate 12 and guide pin 25 due to action of magnetic gap and magnetic field in the magnetic circuit 20. When the direction of power supply to the coil 10 is inverted, the direction of motion is also inverted. The output shaft is drawn out to the outside, through either output shaft hole 24 in the yokes 22a, 22b, or the output shaft hole in upper or lowr cover 31, 32.
