Abstract: An original feeding device includes a pick-up roller, a separation feeding unit, a first original presence/absence detecting sensor, a second original presence/absence detecting sensor and a control unit. When an original is detected by the first and second original presence/absence detecting sensors, the control unit discriminates that the original on the original tray has a first width. When the original is detected by the first original presence/absence detecting sensor but is not detected by the second original presence/absence detecting sensor, the control unit discriminates that the original has a second width smaller than the first width. After the control unit discriminates that the original has the second width and then feeding of the original is started, and then the original is detected by the second original presence/absence detecting sensor, the control unit stops the drive of the pick-up roller and the drive of the separation feeding unit.

Abstract: A document feeding apparatus includes a document tray, a feed roller, a separation conveying unit, a first detecting unit and a control unit. The first detecting unit detects that the document is at the first detecting position when a protrusion amount of a flag member is a first amount and detects that no document is at the first detecting position when the protrusion amount is a second amount. The control unit executes an operation in a first mode in which a first detecting process is executed so as to detect the presence or absence of the document before starting to lower the feed roller and the presence or absence is determined, and in a second mode in which a second detecting process is executed so as to detect the presence or absence at the first detecting position after lowering said feed roller and the presence or absence is determined.

Abstract: An integrated control system for an automatic guided vehicle in a vehicle production line includes: a plurality of the automatic guided vehicles each conveying a conveyance object which is a vehicle; a map construction unit that acquires a map of the vehicle production line; a position information acquisition unit that acquires position information of the plurality of the automatic guided vehicles on the map; a production instruction acquisition unit that acquires vehicle information of each of the vehicles conveyed by the plurality of the automatic guided vehicles; and an operation control unit that controls movement of each of the plurality of the automatic guided vehicles on the map based on the position information and the vehicle information.

Abstract: A control device acquires a first two-dimensional position of a cam bolt and a locknut in a first direction based on a first actual image captured by a first camera, and based on the acquired first two-dimensional position, the control device moves an adjustment socket to a position where the adjustment socket is fittable to a head of the cam bolt and moves a tightening socket to a position where the tightening socket is fittable to the locknut. Then, the control device acquires a second two-dimensional position of the cam bolt and the locknut in a second direction based on a second actual image captured by a second camera, and corrects, based on the acquired second two-dimensional position, a position of the adjustment socket relative to the head of the cam bolt and a position of the tightening socket relative to the locknut.

Abstract: A conveyance apparatus includes a separation unit configured to separate and convey a sheet, a detection unit configured to detect a height-direction deformation of the sheet passing through the separation unit on a downstream side of a sheet-conveying position of the separation unit in a conveyance direction of the sheet, and a control unit configured to stop the sheet conveyed by the separation unit if the detection unit detects the deformation of the sheet.

Abstract: A conveyance apparatus includes a separation unit configured to separate and convey a sheet, a detection unit configured to detect a floating of the sheet passing through the separation unit, and a control unit configured to stop separate conveyance by the separation unit if the detection unit detects the sheet for not less than a predetermined time and/or a predetermined count.
