A movable plate of the document tray is configured to be swingable about a tray shaft and extends leftward. A lifter is configured to be swingable about a lifter shaft extending in the front-rear direction at a position different from the tray shaft. On a lower surface of the movable plate, a cam surface configured to contact a tip of the lifter is formed. The cam surface includes a parallel part parallel to an upper surface of the movable plate and a curved part spaced from the upper surface farther toward a right side. According to a shape of the cam surface, each time the lifter is rotated by a particular angle, the tip of the movable plate moves by a particular amount.Type: GrantFiled: December 22, 2020Date of Patent: April 25, 2023Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshihiro Okamoto, Tomoyuki Mizuno

Patent number: 11511956Abstract: A sheet conveyer having a sheet tray, a tray-driving mechanism, a conveyance guide, a feed roller, a separator, a conveyer, a conveyer-driving mechanism, a controller, and a sheet sensor to detect sheets on the sheet tray, is provided. The conveyer-driving mechanism includes a transmission-active portion and a transmission-passive portion. A conveying velocity to convey the sheets by the conveyer is higher than a conveying velocity to convey the sheets by the feed roller and the separator. The transmission-active portion and the transmission-passive portion are rotatable about a transmission axis. The transmission-passive portion rotates passively by being pushed by the transmission-active portion. After the sheet sensor detects absence of the sheets, and before the transmission-passive portion starts rotating passively, the controller conducts a specific action to move the sheet tray downward by controlling the tray-driving mechanism.Type: GrantFiled: October 27, 2020Date of Patent: November 29, 2022Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshihiro Okamoto, Tomoyuki Mizuno
