  • Patent number: 9505579
    Abstract: A sheet processing apparatus which is capable of reducing the frequency of switching a convey route. The sheet processing apparatus is provided with a switching unit that switches between a first position at which conveyed sheet is led to a first convey path, and a second position at which conveyed sheet is led to a second convey path. A buffering process of overlaying the conveyed sheet conveyed from a buffer path and another sheet subsequently conveyed by the conveyed unit is performed. The second convey path is used by the buffering process when the conveyed sheet to be received into the buffer path is ejected to the second stacking unit, and the first convey path is used by the buffering process when the conveyed sheet to be received into the buffer path is ejected to the first overlaying unit.

  • Publication number: 20160247194
    Abstract: An extraction device includes an acquiring unit, an operation control unit, and an extracting unit. The acquiring unit acquires a distribution request for advertising content including transmission source information. The operation control unit performs a determination process of determining whether an advertising content corresponds to a distribution condition that is set in advance for each advertising content and a calculation process of calculating a score indicating a degree of match between the transmission source information and feature information of the advertising content, with respect to each single advertising content in a group of advertising contents as distribution candidates, on the basis of the transmission source information acquired by the acquiring unit. The extracting unit extracts an advertising content corresponding to the distribution request from the group of the advertising contents on the basis of results of the processes performed by the operation control unit.

  • Patent number: 9309076
    Abstract: A sheet processing apparatus capable of shortening time to align sheets. A first alignment member and a second alignment member are movable in a sheet width direction orthogonal to a sheet conveying direction, and align a sheet. A CPU controls the first and second alignment members to be moved in the sheet width direction. A skew sensor detects a skew amount and skew direction of the sheet. The CPU causes the first and second alignment members to be positioned at respective predetermined standby positions before the sheet is received between the first and second alignment member. Further, the CPU causes one of the first and second alignment members to be moved in a direction toward the sheet, based on the detected skew amount and skew direction, during conveyance of the sheet between the first and second alignment members.

  • Patent number: 9224888
    Abstract: A solar cell has a passivation film formed on a crystalline silicon substrate that has at least a p-n junction, and an electrode formed by printing and heat-treating a conductive paste. The solar cell has a first electrode comprising an extraction electrode, which extracts photogenerated carriers from the silicon substrate, formed so as to contact the silicon substrate and a second collector electrode, which collects the carriers collected at the extraction electrode, formed so as to contact the first electrode. Other than the point of contact between the first electrode and the second electrode, at least, the second electrode contacts the silicon substrate only partially or not at all. By leaving the passivation film between the collector electrode and the silicon, either completely or partially, the solar cell reduces charge losses at electrode/silicon interfaces, improves the short-circuit current and open voltage, and yields improved characteristics.

  • Patent number: 9039002
    Abstract: A sheet post-processing apparatus which is capable of shortening time wasted until actual start of punching and enhancing productivity. A drive unit causes a moving member which has a cam and reciprocates. A punching member is driven by a movement of the cam of the moving member and punches a sheet when the moving member moves forth and moves back. A determination unit determines a type of the sheet. A control unit controls, when a sheet to be punched is to be subjected to a punching process, the drive unit such that the moving member starts moving before conveyance of the sheet to be punched stops, and controls, when the sheet to be punched is to be subjected to the punching process, the drive unit such that timing with which the moving member starts moving is changed based on the determination by the determination unit.

  • Patent number: 9008855
    Abstract: An accumulated use time for cargo handling vehicles is accurately displayed by a time measuring device even if the time measuring device fails and is replaced. Units such as a display unit and a control unit of the cargo handling vehicle each include a time measuring device and a storage device. The device may perform in a synchronization mode in which the difference between the accumulated use times of both devices is made the same and a synchronization inhibition mode in which the accumulated use times are not changed. The accumulated use times are communicated between the function units, and the accumulated use time of the cargo handling vehicle and the absolute value of the difference between the accumulated use times of both measuring devices are taken into consideration. The appropriate mode is selected and the time measurement is carried out in the selected mode.

  • Patent number: 8894057
    Abstract: A sheet processing apparatus capable of detecting a lateral position deviation amount of a sheet with high precision and at a high speed. A sheet sensing unit includes two or more sensors, each of which sensing a side edge of the sheet, disposed in a widthwise direction of the sheet. A position deviation amount of the sheet in the widthwise direction is detected based on a moving distance of the sheet sensing unit until at least one of the sensors senses the side edge of the sheet. The position deviation amount of the sheet is determined using a sensing result of the side edge of sheet after the sheet sensing unit moves by a predetermined distance, while invalidating a sensing result of the side edge of sheet sensing unit in the widthwise direction from when a driving unit starts driving until the sheet sensing unit moves by the predetermined distance.

  • Patent number: 8844922
    Abstract: A sheet processing apparatus which enables a sheet to be stopped at a target position with precision even when the sheet is stopped by moving a heavy unit such as a shift unit. A drive unit moves a moving unit so as to move a sheet, which is being conveyed, in a direction perpendicular to a conveying direction of the sheet. An output unit detects movement of the moving unit and output a signal in synchronization with movement of the moving unit. A control unit issues a stop instruction to the drive unit based on a delay time from when a start instruction to the drive unit is issued until when the signal in synchronization with the movement of the drive unit is output, and a target moving amount required for the moving unit to move to a target position.

  • Patent number: 8833751
    Abstract: A sheet processing apparatus capable of shortening a time period required to determine whether or not a sheet bundle has been normally stapled, while suppressing an increase of apparatus size and an increase of apparatus manufacturing cost, and capable of stacking sheet bundles on a sheet discharge tray such that sheet bundles not normally stapled can be distinguished from normally stapled sheet bundles. When the absence of staple is detected in a sheet bundle by one or both of staple detecting sensors, sheet bundles starting from a sheet bundle to be discharged next are shifted on a processing tray, whereby a sheet discharge position of the next and subsequent sheet bundles on the sheet discharge tray is changed.
