20090200934 | DISPLAY APPARATUS - Provided is a display apparatus capable of reducing external light reflection to reduce an amount of glare of the outside, in which a translucent protection member is provided to cover an observation surface side of a display member including an organic EL light-emitting portion, in order to protect the display member. The display apparatus includes the display member with an organic EL light-emitting portion having a pair of electrodes and an organic compound layer provided between the pair of electrodes; and a casing for housing the display member, wherein a protection member is provided in the casing with a gap from the display member, and wherein a phase member and a polarizing member are formed on the protection member such that the polarizing member is located closer to a light extraction side than the phase member. | 08-13-2009 |
20130265657 | IMAGE PICKUP APPARATUS AND LENS UNIT - A first lens unit performing communication with an image pickup apparatus with a first voltage and a second lens unit performing communication with the image pickup apparatus with a second voltage are selectively attached to the image pickup apparatus. The image pickup apparatus includes a controller configured to operate with a third voltage different from at least one of the first and second voltages to output a signal for the communication with the first and second lens units, and a determiner configured to determine the type of the lens unit attached to the image pickup apparatus. The controller is configured to produce, as a voltage of the signal for the communication, from the third voltage, one of the first and second voltages corresponding to a determination result of the determiner. | 10-10-2013 |
20130266303 | CAMERA ACCESSORY AND CAMERA - The camera accessory is attachable to a camera by relatively rotating from a first state to a second state. Camera side contact pins include a first camera side contact pin making contact with an accessory side contact holding portion in the first state and second camera side contact pins not making contact with the accessory side contact holding portion in the first state. Accessory side contact surfaces include a first accessory side contact surface making contact with the first camera side contact pin in the second state and second accessory side contact surfaces not making contact with the first camera side contact pin in the second state. A pitch between the first and second accessory side contact surfaces adjacent thereto is larger than a pitch between the second accessory side contact surfaces adjacent to each other. | 10-10-2013 |
20130266304 | CAMERA AND CAMERA ACCESSORY - The camera side mount is brought, by relative rotation with the accessory side mount, from a first state where each accessory side bayonet claw is inserted between the camera side bayonet claws into a second state where the camera side and accessory side bayonet claws engage with each other. The leaf spring biasing the camera side contact pins in the protruding direction is disposed between the camera side mount and the camera body. When the camera being in the normal position is viewed from the direction facing the camera side mount, the leaf spring extends from both sides of the mount center line, which extends from the center of the camera side mount in the direction of gravity, toward the camera side contact pins. The camera side contact pins are arranged at positions other than a position on the mount center line. | 10-10-2013 |
20130287388 | CAMERA ACCESSORY AND CAMERA - The camera accessory is attachable to a camera. The camera accessory includes an accessory mount to be detachably coupled with a camera mount). The accessory mount is provided with accessory bayonet claws and brought, by relative rotation with the camera mount, from a first state in which each of the accessory bayonet claws is inserted between camera bayonet claws provided in the camera mount into a second state in which the accessory bayonet claws engage with the camera bayonet claws to complete coupling of the accessory and camera mounts. The camera accessory is further provided with accessory contact surfaces arranged in a relative rotation direction of the mounts in the accessory mount. The accessory contact surfaces includes a first accessory contact surface used for indicating type of the camera accessory and is provided adjacent to the accessory bayonet claw. | 10-31-2013 |
20150049244 | CAMERA AND CAMERA ACCESSORY - The present invention provides the following camera. A first camera-side contact pin is a pin corresponding to detection of a signal change caused by coupling of a camera accessory. A second camera-side contact pin is a pin corresponding to supply of power for communication with the coupled camera accessory. A third camera-side contact pin is a pin corresponding to supply of a driving force to an actuator of the camera accessory. The first, second, and third camera-side contact pins are disposed in such a manner that, when a camera-side mount shifts from a first state to a second state, the third camera-side contact pin contacts first and second accessory-side contact surfaces, the second camera-side contact pin contacts the first accessory-side contact surface, and the first camera-side contact pin does not contact the second and third accessory-side contact surfaces. | 02-19-2015 |
