Abstract: When two or more sheets of paper P are fed in an overlapped manner to a nip where a paper feed roller and a separation roller are in pressure contact with each other, a sub-CPU of a sheet feeding unit rotates the paper feed roller in a paper feeding direction and rotates the separation roller in a direction opposite to the feeding direction, so as to separate overlapping, and thereafter, it rotates the paper feed roller and the separation roller again in the feeding direction.

Abstract: An image forming apparatus comprising: a main body having an image forming section; a sheet feed section having a sheet cassette that accommodates a recording sheet and can be drawn out and loaded to the main body; and a sheet misalignment preventing mechanism that intermittently comes into contact with an uppermost recording sheet in the sheet cassette so as to prevent misalignment of the recording sheet in a loading direction when the sheet cassette drawn out of the main body is reloaded.

Abstract: In a fixing unit, a fixing roller is rotated under driving force transmitted from a paper discharge unit-side gear of a driving section via a fixing roller driving gear, and holds and conveys a recording medium in cooperation with a pressure roller in a nip region. When a control section determines that acceleration conditions are fulfilled, the driving section increases the rotating speed of the paper discharge unit-side gear so that it is rotated at higher speed than before-acceleration speed over predetermined high-speed rotating period.

Abstract: As one embodiment, a paper feeding device is provided with a pickup roller for pulling out an uppermost positioned sheet of loaded sheets, and a paper feeding roller for transporting the sheet pulled out by the pickup roller. Spanning between the pickup roller and the paper feeding roller, a roller belt is provided that is capable of moving relatively in a circumferential direction with respect to an outer circumferential surface of the paper feeding roller. The roller belt obtains rotational drive from the pickup roller.

Abstract: Through screening using an antibody to a polypeptide that constitutes a parasporal body in sporangia of Bacillus popilliae and has a larvae growth inhibiting or insecticidal effect on a Scarabaeidae insect and through polymerase chain reaction, polynucleotides encoding the polypeptide and polypeptides similar thereto are isolated.

Abstract: A paper feeding device 200 provided in an image forming apparatus 1A according to one embodiment of the present invention is provided with a loading member 201 in which sheets P can be stacked and a central bending section 210 configured to upwardly raise a sheet transport direction X central area P2 of the sheet P for sheets P stacked in the loading member 201.

Abstract: In a fixing device, a heat roller and a fixing gear for rotating the heat roller are arranged concentrically, and coupled to each other by inserting a key formed in the fixing gear into a keyway formed in the heat roller. The keyway is designed such that the key is allowed to move along a direction in which the heat roller is rotated. For example, the keyway is formed by notching a free end of a one-side rotary shaft of the heat roller so as to extend along the direction in which the heat roller is rotated.

Abstract: A sheet feeding apparatus includes first and second sheet sensors provided in order from upstream to downstream sides in feeding direction on a paper feed path, sheet conveyor roller sets arranged along the path, and a roller controller individually controlling groups of rollers on the upstream and downstream sides of the first sheet sensor, in response to a change in values of output signals from first and second sheet sensors. The roller controller includes an overlapped feeding determining device outputting a determination signal assuming a first value when overlapped feeding occurs and a second value otherwise, in response to the change in values of the output signals from the sensors, an overlapped feeding eliminating device eliminating overlapped feeding by controlling the roller controller upon receiving the determination signal of the first value, and a conveyor roller stopping device stopping the sheet conveyor rollers if the overlapped feeding eliminating process should fail.

Abstract: In the present glossy paper, an opposite surface of a glossed and smooth image formation surface is rough-surfaced. Therefore, the glossy paper do not adhere together even under the high-temperature and high-humidity environment. In fact, the present invention provides glossy paper which can advantageously achieve a continuous paper feeding in the image forming apparatus regardless of the use environment conditions.

Abstract: A manual sheet feeding mechanism adapted for use in a sheet processing apparatus includes a manual feeding tray and a guiding member. The manual feeding tray is adapted to be mounted on a side wall of the apparatus so as to be pivotable about an axis between an open position and a closed position. The manual feeding tray has a placement surface for placing a sheet to be manually fed into the apparatus. The guiding member is adapted to position a sheet placed on the placement surface and is provided so as to be movable on the placement surface. The manual sheet feeding mechanism also includes a moving member that is adapted, when the manual feeding tray is pivoted toward the closed position, to move the guiding member on the placement surface.

Abstract: A simulation device capable of verifying coordinated operation of software and hardware faster and more accurately. The simulation device has a framework including a virtual OS and a virtual CPU to execute software under test. The virtual OS and CPU also serve as a first scheduler that manages an execution schedule for the software under test. The framework includes a communication interface for communication between the software under test and hardware models. A second scheduler manages simulation processes of the framework and the hardware model. The virtual OS and CPU release their execution right to the second scheduler according to the execution schedule of the software under test.

Abstract: A feeding device according to the present invention holds a pile of sheets of paper in it. Feed force so acts selectively on a specified region of the upper side of the held top sheet as to feed the held sheets one after one in a feed direction.
