Title: Photographing device
Inventor: MIYAMORI KENICHI
IPC: H04N5/232
Filed: 1987-03-05
Abstract: PURPOSE:To reduce man-hours by driving a support device in the panning direction or pitching direction while supplying power to a stator winding thereby constituting the titled device with small size and light weight thereby allowing a photographer for handy photographing. CONSTITUTION:If a lens barrel 23 is rocked in the pitching direction, a control circuit 41 supplies powder to a stator winding 38 of an actuator 43 to make the output of an angular velocity sensor 40 sending the rocking in the pitching direction zero. Then the device is driven in a direction opposite to an arrow I to prevent blurring in the pitching direction. Moreover, the blurring is prevented similarly in an oblique direction. Furthermore, if an oblique deviation takes place, an angular velocity sensor 39 (for panning direction) and an angular velocity sensor 40 (tilting direction) detect the rocking quantity and the control circuit 41 supplies power to stator windings 31, 38 of the actuators 42, 43 to make the output of the sensors in both the directions zero thereby preventing the blurring in the tilting direction.
