A medium transporting apparatus includes a transport belt that has a loop shaped, a cling mechanism that causes the medium to cling to the transport belt, a rotation mechanism that transports the medium by rotating the transport belt, a plurality of detection units that detect an transport direction end of the medium, a controller that corrects a skew of the medium, and a stacker on which the medium transported by the transport belt is stacked, in which the plurality of detection units are arranged at positions that are on an upstream side of the transport belt in the first transport direction and that are different from each other in a width direction, and the controller corrects, according to a result of the detection by the detection units, the skew of the medium in a state of being cling to the transport belt.

This disclosure relates to a winding machine which has a plurality of equi-rotating rolls, at least two guide elements arranged mirror-wise, between which the sheets to be rolled up pass, with arched distal portions arranged in a mirror-like manner, the two guide elements being connected to a support configured to position in a mutually exclusive manner only one guide element at a time in the rolling space defined between the winding rollers. Moreover, the winding machine is equipped with a motor unit controlled so as to rotate the winding rollers in a direction or in the opposite direction depending on which of the two guide elements has its respective distal portion facing the rolling space.

A document conveying device includes a document tray, a first rotary member, a first motor, a second rotary member, a second motor, a document feed sensor, and a controller. The controller counts a counted time from the time point that the first motor starts to rotate until the leading end of a document reaches the document feed sensor. When the time resulting from subtracting the counted time from a required sheet-to-sheet time interval is longer than the required speed change time, the controller performs deceleration and post-deceleration acceleration for the first motor. The required speed change time is the time required for speed change from the first rotation speed to the second rotation speed.

An image forming apparatus includes a main body, a feeder, and a relay device. The main body forms an image on a sheet. The feeder feeds the sheet toward the main body. The relay device connects the main body to the feeder. The main body is placed on a placement surface. The feeder is arranged opposite to the main body with the relay device therebetween in a direction along the placement surface. The relay device includes a conveyance unit and a casing which houses the conveyance unit. The conveyance unit conveys the sheet fed from the feeder to the main body and rotates relative to the casing with an axis as a pivot thereof. The axis extends in a cross direction intersecting with the placement surface.

An image reading apparatus includes a reading unit, a transport unit that transport a document, a feeding unit that transports the document to the transport unit, a controller that stops the feeding operation of the feeding unit after the leading end of the preceding document transported from the feeding unit reaches the transport unit and restarts the feeding operation after the rear end of the preceding document passes a predetermined position. The controller, restarts the feeding operation a first time after the rear end of the succeeding document following the preceding document passes the predetermined position when a size of the preceding document indicates a first size, and restarts the feeding operation a second time after the rear end of the succeeding document passes the predetermined position where the second time is longer than the first time when the size indicates a second size larger than the first size.

A sheet processing apparatus comprising: a conveying unit configured to have a roller that conveys a sheet in a conveyance direction; a first detecting device disposed downstream of the conveying unit in the conveyance direction; a second detecting device disposed downstream of the first detecting device in the conveyance direction; a boring unit configured to have a punch that performs boring in the sheet; and a control unit is used. The first detecting device and the second detecting device each detect passage of a leading edge of the sheet being conveyed. The control unit calculates an actual conveyance speed of the sheet on the basis of detection results of the first detecting device and the second detecting device, and controls rotation of the roller, on the basis of the actual conveyance speed, so that the sheet is conveyed at a predetermined target speed.

Example implementations relate to print media rollers. For example, implementations can include a device that includes a first roller to receive print media, a first sensor to determine when a leading edge of the print media is at a first location, a second roller to be activated based on a type of the print media and when the leading edge of the print media interacts with the first sensor, a second sensor to determine when the leading edge of the print media is at a second location, wherein the first roller is deactivated based on when the leading edge of the print media interacts with the second sensor.
