A system for detecting envelopes from multi-fed documents in a scanning system with a scanning track along which documents move laterally toward a scanning station having a plurality of spaced apart penetrating detectors across the scanning track. The scanners detect a leading edge as a single layer material, i.e. without an air gap and the interior as having an air gap in the document scanned. If a document has an interior air gap, but the leading edge does not, it is first assumed to be an envelope.

A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.

A sheet conveying device includes a first sheet conveyance passage, a second sheet conveyance passage, and a branching guide. The first sheet conveyance passage is a passage through which a sheet passes in a first direction. The second sheet conveyance passage shares a part of the first sheet conveyance passage and branches off from the first sheet conveyance passage in a second direction opposite the first direction of the first sheet conveyance passage. The branching guide is disposed at a position where the first sheet conveyance passage meets the second sheet conveyance passage. The branching guide is configured to move between a first position for the first direction and a second position for the second direction. A plurality of branching guides including the branching guide is spaced apart in a width direction of the sheet and separately switchable between the first position and the second position.

A lottery ticket is printed on a substrate sheet material having a front surface with lottery game indicia printed thereon and a removable covering material, typically scratch-off material, covering the lottery game indicia which is removable by a player to expose the game indicia for playing the game and other game information printed on the substrate sheet material where at least part of the substrate sheet material is formed of a translucent synthetic material to enable viewing through the part by the player. In order to allow the ticket to be dispensed in a row of the tickets from a dispensing machine with an optical sensor, a patch of an opaque or semi-opaque material is applied onto the substrate at a location to cooperate with the sensor while it is operating to detect ticket location.

Provided are a medium conveyance apparatus, control method, and control program to enable determining whether multi-feed of a medium has occurred by a greater precision. A medium conveyance apparatus includes a storage device to store in advance region information of a predetermined region in a medium, a feed roller to feed the medium, a slant detection module to detect an amount of slant of the fed medium, an overlap detection module to detect region information of a region in which overlap has occurred in the fed medium, a correction module to correct the detected region information based on the amount of slant, and a multi-feed determination module to determine that multi-feed of the medium has occurred if the corrected region information does not correspond to the stored region information and determine that multi-feed of the medium has not occurred if the corrected region information corresponds to the stored region information.

The present invention provides an image forming apparatus that reduces image artifacts caused by the back tension of a separating unit. A control unit decreases the number of rotations (the rotational speed) of a resist roller pair after the leading edge of a sheet reaches a transfer position.

In a printing apparatus, the ends of print media fed continuously can be prevented from colliding with each other. The printing apparatus includes a printing unit configured to perform a print operation, a detecting unit configured to detect a conveyance abnormality, a conveying unit configured to convey a preceding print medium and a succeeding print medium, a conveying path having a first area including a curved portion at which a conveying direction of the print medium is curved and a second area upstream of the first area, and an opening unit capable of opening the first area of the conveying path. In a case in which a leading edge of the succeeding print medium is located in the second area at the time of the detecting unit detecting conveyance abnormality of the preceding print medium, the conveying unit conveys the succeeding print medium so that the leading edge of the succeeding print medium reaches the first area.
