Registering Devices TRIZ Cases

Belt transport device adjusts upper conveyor height to match printed product thickness for continuous feeding.

Swinging guide portions dynamically widen the path interval to correct skew in heavy media while preventing jams in thin media.

Forward and backward feeder gate motion aligns document lead edges, eliminating manual pre-alignment steps and reducing scanning jams.

An integrated rear end regulating member moves with the slide cassette to eliminate separate adjustment operations and reduce device complexity.

Automated register sensor evaluation region definition prevents manual adjustment errors in printing substrate processing.

Differential velocity drives adjust roller speeds to correct skew without stopping the feed, reducing noise and complexity.

Movable regulation guides shift between guide and retract positions to reduce friction-induced jamming, preserving sheet conveyance reliability.

Controller activates lateral or register aligners based on sheet basis weight to correct positional deviations during conveyance.

Unidirectional shutter rotation eliminates reciprocating return time, reducing sheet spacing and boosting throughput.

Dynamic roller separation timing based on conveyance path reduces loop reaction forces, preventing wrinkles and scratches.

A printing system uses a resist roller and passage detection sensor to maintain constant paper slack during conveyance.

A paper conveying device uses an engaging roller unit to align sheets during rotation.

Differential roller speeds correct media skew detected by sensors, preventing jams without increasing device complexity.

A gripping section holds sheet centers during horizontal plate withdrawal to maintain width alignment.

An omni-wheel sheet conveying system employs pivotable elongate guides to correct lateral misalignment of printed cardboard sheets before processing.

A guide member tilts toward the inner curvature of a conveying path to manage sheet rigidity during transport.

A sheet conveying device determines conveyance states by analyzing motor torque changes between feed rollers and downstream units.

Sequential roller control reduces trailing edge flapping noise while maintaining slack to prevent sheet expansion noise.

A sheet alignment method adjusts conveying force during widthwise positioning to prevent skewing.

Dynamic roller positioning resolves detection accuracy versus device complexity trade-offs for varying sheet widths.

A sheet conveyance guide member pivots against a dedicated abutment portion to limit its rotation range.

A sheet aligning apparatus uses an electrostatic capacitance sensor to detect shifting sheets and automatically adjust the front aligning member position.
