摘要： A paper feeder includes a storage section, a feed path, a delivery section, and a receiving section. The storage section is configured to store therein plural sheet members to be fed to a processing apparatus which is operative to perform processing on the sheet members. The feed path allows each of the plural sheet members fed from the storage section to pass therethrough in a feed direction toward the processing apparatus. The delivery section is located most downstream on the feed path in the feed direction. The feed path is open to exterior in the delivery section. The receiving section is located upstream of the feed path in the feed direction for communication with a delivery section of a separate paper feeder having an identical construction with the present paper feeder when the separate paper feeder is disposed upstream of the present paper feeder in the feed direction.

摘要： A paper feeder comprises an acquiring device, a driving roller, driven rollers, a driven roller supporter, a driver, and a controller. The acquiring device acquires thickness information on a sheet of paper. The driving roller rotates by being supplied with torque. The driven rollers rotate with the driving roller when in compressive contact with the driving roller. The driven roller supporter so supports the driven rollers that each of them can rotate under a different rotational load. The driver changes the position of the driven roller supporter relative to the driving roller. The controller selects one of the driven rollers on the basis of the thickness information and so activates the driver as to bring the selected roller into compressive contact with the driving roller.

摘要： A sheet feeder has a feed passage and includes feed roller pairs, sensors, and a controller. The feed roller pairs are arranged along the feed passage and feed sheets of paper in a feed direction along the passage by nipping the sheets. Each of the sensors is fitted at or near one of the feed roller pairs and senses a specified point on each of the sheets when the sheet is nipped by at least the associated roller pair. The controller includes a memory for storing reference feed timings as proper feed timings at each of which the specified points on the sheets should pass one of the sensors. The controller finds the real feed timing when each of the sensors senses the specified point on the sheet nipped by at least the associated roller pair. When each of the sensors senses the specified point on the sheet nipped by at least the associated roller pair, the controller finds the time difference between the associated reference feed timing and the associated real feed timing and controls, according to the found time difference, the feed speed at which the feed roller pair or pairs nipping the sheet feed it.
