Patent number: 10416346Abstract: A photosensor includes a light projection unit, a light receiving unit, a determination unit that determines a magnitude relation between a received light quantity of the light receiving unit and a threshold value set for the received light quantity; and a threshold value setting unit that sets the threshold value of the received light quantity. The threshold value setting unit calculates for each of a plurality of different wavelength regions, a contrast difference that is a difference between a received light quantity obtained when projection is performed on a detection target on a surface of a workpiece and a received light quantity obtained when projection is performed on a background on the surface of the workpiece, and updates the threshold value based on the contrast difference for a wavelength region among the plurality of wavelength regions in which the contrast difference has a maximum value.Type: GrantFiled: December 15, 2017Date of Patent: September 17, 2019Assignee: OMRON CorporationInventors: Hironobu Morita, Motoharu Okuno, Yasuhito Uetsuji, Kazunari Komai, Takuya Matsushima, Yusuke Iida, Seho Seo

Patent number: 8575636Abstract: A first light-blocking member and a second light-blocking member are adhered to each other by forming a light-transmitting layer having a light-transmitting composition serving as a base material and a light-transmitting filler different in index of refraction from this light-transmitting composition on a front surface of the first light-blocking member. A liquid light curing adhesive is applied to a front surface of the light-transmitting layer. The second light-blocking member is arranged on the front surface of the light-transmitting layer to which the liquid light curing adhesive has been applied. The liquid light curing adhesive is cured by irradiating the light-transmitting layer with light having a prescribed wavelength laterally from a side of the light-transmitting layer so as to adhere the light-transmitting layer and the second light-blocking member to each other.Type: GrantFiled: October 14, 2009Date of Patent: November 5, 2013Assignee: OMRON CorporationInventors: Yuki Ushiro, Takamasa Kameda, Kazunari Komai, Tsuyoshi Miyata, Motoharu Okuno, Makoto Kasuya
