Patent number: 11932511Abstract: A medium feeding mechanism includes: a feeder that feeds a medium; a transport path that is coupled to the feeder; a transporter that transports the medium through the transport path; a transport drive that drives the transporter; an entry detection sensor that detects when the medium fed from the feeder has entered the transport path; a take-in transporter that takes in the medium transported by the transporter; and a transport controller that controls the feeder and the take-in transporter, wherein when the entry detection sensor detects entry of the medium at a time that falls within a first range set in advance, the controller controls the take-in transporter so as to take in the medium, and when the entry detection sensor detects entry of the medium at a time that falls within a second range following the first range.Type: GrantFiled: December 21, 2021Date of Patent: March 19, 2024Assignee: RISO KAGAKU CORPORATIONInventor: Yuzuru Iioka

Publication number: 20220194723Abstract: A controller controls a floating unit and a conveyor to convey a sheet to a supply destination, and performs a following control of acquiring a detection value of a detector which detects an output signal acquired due to an input to a side of a sheet stack, during floating of sheets floated by the floating unit each time a sheet is conveyed by the conveyor and lifting a stacking tray upon the acquired detection value being less than a threshold value. The controller controls the floating unit and the conveyor to perform a feeding retry upon an occurrence of empty feeding in the conveyor, and determines the threshold value such that a target position for a height position of an upper surface of the sheet stack in the following control is a position where empty feeding is more likely to occur than multiple sheet feeding in the conveyor.Type: ApplicationFiled: December 15, 2021Publication date: June 23, 2022Applicant: RISO KAGAKU CORPORATIONInventors: Yuzuru IIOKA, Ryosuke MIYACHI
