Patent number: 11308296Abstract: An optical information reading device 100 includes an aiming module 60 configured to irradiate aiming light for instructing an imaging area of image data generated by an imaging module, a trigger switch 30 for starting imaging processing by the imaging module, an aiming switch 43B for causing the aiming module 60 to irradiate the aiming light, and a reading unit 81 configured to read information of the symbol. The reading unit 81 is configured to, in an aiming state in which irradiation processing for the aiming light by the aiming module 60 is executed by operation of the aiming switch 43B, detect that the trigger switch 30 is operated and read, based on the image data generated by the imaging processing of the imaging module, information of the symbol included in a predetermined partial area PA corresponding to an irradiation position of the aiming light.Type: GrantFiled: March 13, 2020Date of Patent: April 19, 2022Assignee: KEYENCE CORPORATIONInventors: Hiroomi Ohori, Tomomi Izaki

Patent number: 10515249Abstract: [Object] To enhance accuracy at the time of setting with consideration of a cell size of a code when an exposure time is automatically set. [Means to solve the problems] An upper limit of an exposure time of an imaging part as a restriction condition for reading a code attached to a workpiece is calculated based on a moving speed of the workpiece, which is inputted by an input part, and a cell size, which is calculated by a cell size calculation part. An exposure time of the imaging part is set within the restriction condition by analyzing a plurality of images, which includes a code and is obtained by taking images multiple times by changing the exposure time of the imaging part.Type: GrantFiled: February 22, 2019Date of Patent: December 24, 2019Assignee: Keyence CorporationInventors: Hidezumi Nagata, Taichi Tajika, Hiroomi Ohori, Taiga Nomi

Patent number: 10268853Abstract: [Object] To enhance a reading accuracy of a code even when a light amount, which can be received by an imaging element, varies greatly. [Means to solve the problems] A plurality of second images in response to a plurality of different conversion characteristics is generated by using the first image obtained at the time of setting of an optical information reading device. The results, in which codes included in the generated second images are respectively decoded by a decoding part, are analyzed, and one of the conversion characteristics is selected. The second image in response to the selected conversion characteristic is generated by using the first image at the time of operation of the optical information reading device.Type: GrantFiled: December 21, 2017Date of Patent: April 23, 2019Assignee: Keyence CorporationInventors: Hidezumi Nagata, Taichi Tajika, Hiroomi Ohori, Taiga Nomi
