  • Patent number: 8958120
    Abstract: A print control apparatus includes an obtaining unit and a specification unit. The obtaining unit obtains positional information for specifying positions of ends of a print medium detected by a sensor when the print medium is conveyed along a conveyance path such that a print medium center is aligned with a conveyance path center. The specification unit specifies, when positions of both ends of the print medium are specified by the obtained positional information, a width of the print medium in accordance with the specified positions of both ends, and specifies, when the position of only one end of the print medium is specified by the positional information, a width corresponding to a length twice as long as a distance between the specified position of the one end of the print medium and a position corresponding to the conveyance path center as the width of the print medium.

  • Patent number: 8936241
    Abstract: An articulating sheet guide is used in connection with a printing system. A primary media transport nip is disposed adjacent a media sheet source supplying a media sheet. A secondary media transport nip is downstream. A link has a front surface facing upstream, and a proximal end pivotally mounted. From adjacent the primary media transport, the link will pivot past the secondary media transport. A link pocket is disposed transversely to the process direction on the link front surface. The V-shaped link pocket is adapted to receive the media leading edge. The primary media transport nip will move the media sheet toward the link. The link pocket will receive the media leading edge. The media sheet movement will cause the link to move in an arcuate path guided by the pivotal movement of the link into engagement by the secondary media transport nip. The link pocket will release the media leading edge. The operation is nearly silent.

    Abstract: A post-processing apparatus which enable reduction of shift alignment time and improvement of productivity. A shift unit performs a shifting operation for shifting a conveyed sheet, in a lateral direction orthogonal to a sheet conveying direction. An alignment unit aligns the sheet by a pair of alignment members thereof which are moved toward each other such side edges of the sheet in the lateral direction are held therebetween. A CPU of a finisher controller controls the alignment unit and the shift unit such that an operation for moving the alignment members from respective first standby positions in the lateral direction to respective second standby positions closer to the sheet than the corresponding first standby positions is executed in parallel with the shifting operation by the shift unit.

  • Patent number: 8851469
    Abstract: A sheet conveying apparatus irradiates a conveyed sheet with light from a light source to receive reflected light by a line sensor and detects a side edge position of the sheet based on an output of a reading pixel of the line sensor. The reading pixel within a predetermined range facing the sheet in the line sensor is determined to be used for light quantity adjustment of the light source based on a size in a width direction orthogonal to a sheet conveying direction, and the light quantity of the light source is adjusted based on the output of the determined reading pixel. A threshold value for detecting the side edge position of the sheet is determined based on outputs of reading pixels within the region facing the sheet and outputs of the reading pixels within the region not facing the sheet in the line sensor.

  • Patent number: 6682068
    Abstract: An automated banking machine (10) identifies and stores documents such as currency bills deposited by a user. The machine then selectively recovers such documents from storage and dispenses them to other users. The machine includes a central transport (70) wherein documents deposited in a stack are unstacked, oriented and identified. The documents are then routed to storage areas in recycling canisters (92, 94, 96, 98). When a user subsequently requests a dispense, documents stored in the storage areas are selectively picked therefrom and delivered to the user through an input/output device (50) of the machine. Sheets are oriented in the central transport by a deskewing/centering device (84). The deskewing/centering device includes a shuttle (204). The shuttle includes transversely disposed pinch wheels (212, 214) and sensors (216, 218, 220). The rotation of the pinch wheels is selectively controlled to orient the leading edges of sheets to extend transversely relative to the sheet path.

    Abstract: A paper conveying device for overrunning paper from a stop position and then, switching the paper back to stop the paper in a stop position. The driving of a paper conveying section for conveying paper is stopped at the time point where the rear end of the paper reaches the stop position. Thereafter, the amount of overrun of the paper is detected, so that the paper is switched back by the amount. Consequently, the amount of overrun and the amount of switchback of the paper are suppressed to the minimum amounts required. In addition, the stress applied to the paper is reduced, and the paper is set in a short time.

  • Patent number: 4373986
    Abstract: This invention concerns an improved gluing machine and a continuous method of operation which allows the gluing process to proceed at a rate that equals the feed rate of vacuum rotary document feeders. The machine includes a unique registry and guide system for efficiently moving documents fed initially in an individual manner in a continuous, flowing manner from an initial input feed device to the gluing and registry point with the carrier. The feed system not only allows substantially greater operating speeds but simultaneously overlaps documents while establishing and maintaining correct registration of the documents. The documents are overlapped so that following documents are positioned beneath leading documents. This overlapped condition together with the registry achieved within the feed system assures each individual document arrives in proper registry with areas of glue previously applied at preselected intervals on the carrier sheet.
