A conveying apparatus has first and second trays arranged on an upstream of a conveyor and configured to support the sheet in contact with the conveyor, a feeder configured to feed the sheet on the first tray toward the conveyor, a first sensor configured to output a first signal in response to the sheet being present on the first tray, a second sensor configured to output a second signal in response to the sheet being present between the first tray and the conveyor and configured to output the second signal in response to the sheet being present between the second tray and the conveyor, and a controller configured to execute a removal notifying process to output a notification indicating removal of the sheet on the first tray in response to output of the second signal before a time period since the first signal was output exceeds a threshold period.

In one example a bend sensor is disclosed. The bend sensor extends into a media tray. The bend sensor has a tip where a deflection amount of the tip indicates a media parameter.

A sheet feeding apparatus includes a document tray configured to support a document, a pickup roller configured to feed the sheet supported on the document tray, a separation roller pair configured to separate the sheets fed by the pickup roller one by one, a paddle arranged between the pickup roller and the separation roller pair in a sheet feeding direction and feeding the sheet supported on the document tray, and a drive motor capable of driving the pickup roller, the separation roller pair and the paddle. The paddle feeds the sheet supported on the document tray with a conveyance force weaker than the pickup roller.

A sheet detecting apparatus including: a detection unit including a lever member having an abutment surface abutting a conveying sheet and a holding member configured to hold the lever member, the detection unit moved by the lever member pushed by the sheet; a first urging portion configured to urge the holding member to a waiting position after the sheet is separated from the abutment surface; a support portion configured to support the lever member movable with respect to the holding member to move the lever member to a retracted position for allowing the sheet to pass the lever member contacting a surface of the sheet when the holding member is in the waiting position; and a second urging portion configured to urge the lever member so that the lever member is moved from the retracted position to a position in which the abutment surface abuts a succeeding sheet.

A sheet feeding apparatus, including: a stacking unit; a feed unit having a contact portion to be brought into contact with a sheet stacked on the stacking unit and a noncontact portion kept out of contact with the sheet, the feed unit being configured to feed the sheet in a contact state in which the contact portion is in contact with the sheet, and then turn into a noncontact state in which the noncontact portion faces the sheet so as to be kept out of contact with the sheet; a conveyance unit arranged downstream of the feed unit; and a drive unit configured to drive the conveyance unit at a first speed in the contact state and to drive the conveyance unit at a second speed higher than the first speed in the noncontact state.
