    摘要: PROBLEM TO BE SOLVED: To provide a sheet supply device and an image forming device capable of surely supplying a sheet in a short time, even if the sheets of upper limit capacities are placed on a lifting plate for lifting a document placed on a document tray.
    SOLUTION: In a document set position, when detecting a document bundle on the document tray by a set switch 603, when an upper limit switch 311 detecting that the lifting plat exists in a carrying proper position is in an on-state, a preliminary operation control part 602 drives a lift motor 503 so as to be liftable by a backlash quantity of a driving system gear of the lifting plate. Thus, even if the lifting plate is brought in a state of being not driven once so as to be liftable after placing the document bundle on the document tray, lifting driving can be started without a delay.

    摘要: PROBLEM TO BE SOLVED: To provide a technology for highly accurately conveying a sheet to a predetermined position.SOLUTION: A printer device executes paper feeding control processing for abutting a sheet on the sheet taking-in position of a conveyance roller from a paper feeding roller by rotating the paper feeding roller positioned on an upstream side forward in the reverse-rotated state of the conveyance roller positioned on the downstream side. Then, the printer device executes paper setting control processing for further taking in the paper to the downstream side by rotating the conveyance roller forward and conveying the sheet to an image forming position. However, during the change from the paper feeding control processing to the paper setting control processing, the sheet naturally rotates. Thus, in the paper setting control processing, the rotational amount δ of the conveyance roller during the change from the paper feeding control processing to the paper setting control processing is first calculated (S430). Then, the target rotational amount of the conveyance roller is corrected by the rotational amount δ (S440). Thus, the sheet is highly accurately conveyed to a predetermined position by suppressing the effect of the rotational amount δ.

    摘要: PROBLEM TO BE SOLVED: To effectively reduce the influence of backlash on a power transmission mechanism between a motor and timing rollers, and reduce relative image shift to be generated between recording sheets as far as possible.SOLUTION: The image forming apparatus includes a convey device which brings a leading edge of a recording sheet into contact with a nip portion of stopped timing rollers, and starts rotation to convey the recording sheet toward a toner image transfer position. The motor is started to rotate the timing rollers at a first rotation speed to convey a first recording sheet. The motor is stopped when the conveyance is completed, and when a second recording sheet to be conveyed next is conveyed at a second rotation speed different from the first rotation speed (No at step S2), the timing rollers are idled at the second rotation speed or at another rotation speed closer to the second rotation speed than the first rotation speed (steps S11 to S13) before starting the conveyance of the second sheet (step S4).
