An improved sheet-position detection system for apparatus having a sheet feed path and a use location(s). The position detection system includes a first capacitive sensor including a first pair of parallel plate members located in opposing relation on opposite sides of the feed path plane and centered on a desired lead sheet edge position. A second capacitive sensor includes a second pair of parallel plate members that are located in opposing relation on opposite sides of the feed plane and are centered on a desired trail sheet edge position. A bridge circuit applies potentials across the pairs of plate members in a circuit configuration such that output signals of the first and second sensors are subtracted, and when the combined outputs of the first and second sensors is zero, a feed sheet is indicated to be centered between the sensor means.

A scuff sheet separating mechanism includes a device for gripping the rear portion of a stack of sheets, not including the one being fed, and pulling the portion gripped away from a sheet separating nip until the sheet is fed. The device includes a pair of fingers which are periodically closed and then laterally reciprocated to grip the stack and pull it away from the nip and move it back into position to separate another sheet. This mechanism is particularly useful in the intermediate tray of a copier or similar apparatus to prevent toner on one side of the sheet being fed from scraping off onto an adjoining sheet because of the force between a scuff device and a feed mechanism.

A sheet movement detection system for apparatus having a sheet feed path includes a first capacitor sensor including a first pair of parallel plate members located in opposing relation on opposite sides of the feed path plane at an upstream position and second capacitor sensor including a second pair of parallel plate members, which are correspondingly sized and spaced to said first plate members, in opposing relation on opposite sides of the feed path plane at a downstream position. The sensors are coupled in a detection circuit which applies potentials across the pairs of plate members so that output signals of the first and second sensing means are subtracted from one another. A position circuit detects the output of the detection circuit during movement of a sheet lead edge through the second sensor and provides a sheet lead-edge position signals indicating the position or velocity of the sheet lead edge.

A sheet transport and aligning apparatus that engages with a sheet to shift the sheet laterally during forward transport of the sheet by a roller. The lateral shift brings the sheet into engagement with a light weight pivotal edge guide which aligns to the sheet to establish a line contact with the sheet as the sheet is driven by the conical drive roller. By continuing to drive the sheet, the sheet pivots with the light weight pivotal edge guide until the sheet is in cross-track and skew alignment.

A flexible coupling for effecting a precisely aligned and repeatable blind mounting of the driver and driven halves thereof at a single time and in a single stage. The drive half can toggle and includes a plurality of multi-length teeth, and the driven half includes a rotatable disc member having a plurality of overlapping sloped slots for fully receiving and engaging the multi-length teeth of the driver half at the time and stage when the driven half is axially moved into the driver half by only a small axial force.
