Publication number: 20240119621Abstract: The present disclosure provides a system for supporting a movement of a moving body in a predetermined area. The system acquires an image captured by an infrastructure camera such that the image includes a plurality of markers arranged in the predetermined area. The system compares the image acquired this time and the image acquired previous time. The system detects a position change marker among the plurality of markers whose position in the image acquired previous time changes from that in the image acquired this time. The system determines that the infrastructure camera is out of position when it is detected that number of the position change marker is equal to or more than a predetermined number. The system determines that the infrastructure camera is not out of position when it is detected that number of the position change marker is less than the predetermined number.Type: ApplicationFiled: September 28, 2023Publication date: April 11, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroya Chiba, Koji Morita, Yuhei Oka, Daisuke Kakuma

Patent number: 11952239Abstract: A sheet feeding device includes a feeding roller pair, a detecting portion, a first changing portion, a second changing portion, and a controller for controlling the first changing portion and the second changing portion. The controller starts a first feeding operation for feeding a sheet toward the obliquely feeding roller pair in a nipping state of the feeding roller pair and then starts a second feeding operation for feeding the sheet for abutting a side end of the sheet against the reference member in the nipping state of the obliquely feeding roller pair. The controller changes, after the first feeding operation is started and before the second feeding operation is started, a start timing of the second feeding operation on the basis of a detection result of a position of the side end of the sheet detected by the detecting portion.Type: GrantFiled: December 1, 2021Date of Patent: April 9, 2024Assignee: Canon Kabushiki KaishaInventors: Yoshinao Chiba, Shingo Iwami, Koji Suzuki, Yuma Inui, Yoshiya Numata
