Patent number: 7104708Abstract: A sector drive unit for a camera includes sectors capable of opening and closing an aperture provided on a base plate. A first actuator drives the sectors to open and close the aperture, and a drive force transmitting mechanism transmits a driving force of the first actuator to the sectors. A sector retaining unit retains the sectors at the aperture-opening position or at the aperture-closing position, and a second actuator drives the sector retaining unit to a position to retain the sectors and to a position not to retain the sectors. The sector retaining unit prevents the sectors from moving accidentally due to an impact or the like when the sectors are at either the opened position or the closed position. The use of the second actuator for driving the sector retaining unit reduces power consumption and prevents generation of noise during the time of an exposure.Type: GrantFiled: April 14, 2004Date of Patent: September 12, 2006Assignee: SEIKO Precision Inc.Inventors: Yoichi Nakano, Hiroshi Takahashi

Patent number: 6642505Abstract: A reflection-type optical sensor is provided wherein misjudgment is prevented in detecting the existence of an object and determining whether a distance to the object is large or small. A housing is molded from white polycarbonate resin and has a light-projecting portion and a light-receiving portion. A light-projecting lens and a light-emitting device are mounted in a light-projecting chamber formed in the light-projecting portion. A light-receiving lens and a light-receiving device are mounted in a light-receiving chamber formed in the light-receiving portion. Those of the wall surfaces of the light-projecting chamber and the light-receiving chamber which are illuminated with light are light reflection-promoting surfaces that promote the reflection of light.

Publication number: 20030107656Abstract: To reduce power consumption of an image pick-up device in which an object to be photographed is illuminated, during a period until a release switch is operated, a control part controls a light emitting part to emit a smaller quantity of light than that necessary for photographing the object. When a photographing instruction is output by the release switch, the control part controls the light emitting part to emit light with the quantity of light necessary for photographing the object.Type: ApplicationFiled: December 9, 2002Publication date: June 12, 2003Inventors: Akira Ito, Yoichi Seki, Yoichi Nakano, Hirobumi Okuyama

Publication number: 20030107669Abstract: To provide an image pick-up device in which a lens does not need to be driven when information corresponding to the distance to an object to be photographed is obtained by using image information output by an image pick-up part. When a control part determines that an image is darker than a prescribed value based on a luminance signal contained in image information output by an image pick-up part, the control part stores the luminance signal in the image information input from the image pick-up part while a light emitting part does not emit light and then controls the light emitting part to emit light with a prescribed quantity. The control part stores the luminance signal in the image information output by the image pick-up art to obtain the luminance difference between the two luminance signals. When the luminance difference is not larger than a prescribed value, the control part controls the light emitting part to emit light with a prescribed quantity of light.Type: ApplicationFiled: February 10, 2003Publication date: June 12, 2003Inventors: Akira Ito, Yoichi Seki, Yoichi Nakano, Hirobumi Okuyama

Patent number: 6530703Abstract: A focal-plane shutter comprises a shutter plate having a shutter opening, opening blades and closing blades for opening and closing the shutter opening, and arms connected by connector portions to the opening and closing blades for driving the blades parallel to the shutter opening to effect an exposure. Resilient stopping members are disposed to make resilient contact with the opening blades at opening positions thereof where the opening blades are retracted from the shutter opening, and other resilient stopping members are disposed to make resilient contact with the closing blades at closing positions thereof where the closing blades close the shutter opening. The resilient stopping members are positioned on opposite sides of the connector portions so that when the blades strike the stopping members, reaction forces are produced which cancel each other out thereby preventing excessive wear of the connector portions.Type: GrantFiled: February 20, 2002Date of Patent: March 11, 2003Assignee: Seiko Precision Inc.Inventors: Yoichi Nakano, Hiroshi Takahashi
