  • Patent number: 11078054
    Abstract: There is provided a crane including a front member capable of derricking, a backstop disposed on a rear surface side of the front member so as to limit a standing operation of the front member, an angle sensor that detects an angle of the front member, an operation detection unit that detects whether or not the backstop is operated, and a controller that controls a derricking operation of the front member. In a case where the controller determines that the angle of the front member is equal to or larger than a predetermined angle, based on a detection signal output from the angle sensor, and determines that the backstop is not operated, based on a detection signal output from the operation detection unit, the controller stops the standing operation of the front member.

  • Patent number: 7465107
    Abstract: A photographing apparatus which realizes a taking lens barrel whose shape is not largely changed during panning or tilting shot, thereby being compact in size and easy to handle. In the photographing apparatus, an image pickup device (14i) outputs an electric signal from object light. A bending optical system (14) has a front lens (14f) and lens groups (14j, 14k, 14l, and 14m) and a mirror (14c) disposed between the front lens and the laminated lens 14j, to guide the object light to the image pickup device. A panning actuator (19) and a tilt actuator (15f) cause the mirror and the front lens or the lens groups to be pivotally moved in unison about respective different axes to thereby change a shooting direction.

  • Patent number: 6702483
    Abstract: An optical device capable of controlling its optical transmittance. The optical device has a first liquid conductive or having a polarity and a second liquid. The first and second liquids are substantially equal in refractive index but differ in transmittance. The first and second liquids do not mix with each other. The first and second liquids are sealingly contained in a container in such state that the boundary therebetween has a predetermined shape. When a voltage is applied between these liquids through electrodes formed in such a place or condition as to avoid interference with passage of a bundle of rays incident upon the optical element, the output of the applied voltage is selected under control to change the shape of the boundary, thereby changing the quantity of transmitted light in the bundle of rays traveling through the optical device.

  • Patent number: 6317564
    Abstract: A camera includes a plurality of camera operation mechanisms, a sun gear which rotates by means of a motor, a planetary gear which revolves around the sun gear, and a plurality of output gears each capable of meshing with the planetary gear by means of revolution of the planetary gear. The plurality of output gears transmit power to the plurality of camera operation mechanisms, respectively. A holding member is switchable from a first state, in which the planetary gear is allowed to revolve freely, to a second state, in which the planetary gear is held at a revolution position where the planetary gear is in mesh with one of the plurality of output gears. A controller causes the planetary gear to revolve so as to mesh with a selected one of the plurality of output gears, and switches the holding member from the first state to the second state, after completion of a power transmitting operation.

  • Patent number: 6215958
    Abstract: A camera includes a plurality of camera operation mechanisms, a sun gear which rotates by means of a motor, a planetary gear which revolves around the sun gear, and a plurality of output gears each capable of meshing with the planetary gear by means of revolution of the planetary gear. The plurality of output gears transmit power to the plurality of camera operation mechanisms, respectively. An unlocking device removes backlash by causing the planetary gear to rotate temporarily in an opposite direction when the planetary gear is to be switched from one of the plurality of output gears in mesh therewith, to another one of the plurality of output gears. A locking device prevents the planetary gear and such one output gear from coming out of mesh with each other until the backlash is removed when the unlocking device causes the planetary gear to rotate in the opposite direction.

  • Patent number: 6167198
    Abstract: An apparatus, such as a camera, comprises a plurality of operation mechanisms, a first rotation member, such as a sun gear, rotatable by operation of a motor, a second rotation member, such as a planetary gear which revolves around the sun gear, and a plurality of force transmitting members, such as output gears, each capable of meshing with the planetary gear by revolution of the planetary gear around the sun gear, where the plurality of output gears transmit power to the plurality of operation mechanisms, respectively, and a limiting structure, e.g., a stopper that limits revolution of the planetary gear around the sun gear. In one aspect, the limiting structure limits the revolution of the planetary gear at a revolution position where the planetary gear does not mesh with any of the plurality of output gears, and a position of the planetary gear during revolution thereof is determined on the basis of the position where revolution of the planetary gear is limited by the limiting structure, e.g.
