Patent number: 8169624Abstract: There is provided a transmissive dimension measuring device in which a user can intuitively and easily adjust optical axes of a projector and an optical receiver, and in which a suitable action can be immediately taken when contamination is attached to a light projecting surface of the projector and a light receiving surface of the optical receiver. An incident light position display unit provided on the optical receiver expresses a light projecting spot in a pseudo manner by making an LED corresponding to an incident light position turn on, the light projecting spot being incident on the optical receiver arranged with a predetermined interval to the projector which projects light. The incident light position display unit is provided on an upper surface side opposite to a bottom surface that is a surface on which the optical receiver is installed on a base.Type: GrantFiled: March 15, 2010Date of Patent: May 1, 2012Assignee: Keyence CorporationInventors: Tomonari Torii, Noriyoshi Yamane, Ryoichi Tsumori, Kentaro Yamazaki

Patent number: 7249884Abstract: In the head portion, the thermopile is arranged substantially in the center of the head portion. The preamplifier board is arranged near the thermopile. The heat diffusion member made of a high heat conductive material is arranged so as to surround the thermopile and the preamplifier board. The main board and the laser diode are arranged between the upper surface of the head casing and the upper surface of the heat diffusion member. The power supply board and the laser diode are arranged between the down surface of the head casing and the down surface of the heat diffusion member. The thermopile, the preamplifier board, the main board, the power supply board, and the laser diodes are arranged out of contact with the heat diffusion member.Type: GrantFiled: December 30, 2005Date of Patent: July 31, 2007Assignee: Keyence CorporationInventors: Tomonari Torii, Choryon Oh

Patent number: 7034284Abstract: An optical sensor projects light rays emanating from a light emitting element that are collimated by a lens and reflected by a mirror and then directed to a light projecting prism. The collimated light rays incident upon the prism are refracted at an incident surface and come out from the prism through a light exit surface so as thereby to be projected into the field of detection. Light rays passing through the field of detection are directed to a light receiving prism. The light rays incident upon the light receiving prism through a light incident surface are reflected by a light exit surface and then come out from the light receiving prism. The outgoing light rays are received and converted into an electric signal by a light receiving element.Type: GrantFiled: December 29, 2003Date of Patent: April 25, 2006Assignee: Keyence CorporationInventor: Tomonari Torii
