Function Indicators TRIZ Cases

A switchback transport path enables multiple post-processing functions inside the space formed by reading, printing, and feed portions.

Acoustic jam detection triggers automatic recovery processing that resumes paper conveyance based on real-time paper state analysis.

A conveyance guide moves with a first roller to align media entering an imaging unit.

A separation roller assembly uses a torque limiter and two-stage gear to control pressing force against a feed roller.

An elastic conveyance guide redirects curved recording material away from a stripping claw, preventing damage to rotary bodies in image forming apparatuses.

Sorts inspected substrate sheets into quality grades to prevent defective materials from entering security printing workflows.

Periodic forward rotation of the separation roller prevents elastic deformation while reverse rotation ensures reliable medium feeding.

A card separation apparatus uses a movable tray to convey sheets while automatically separating attached cards.

A sheet processing apparatus conveys succeeding bundles to an accumulation portion while performing square back processes on preceding bundles.

A rotatable arm integrates a sensor with a pickup roller to detect sheet presence and tray mounting state.

A flexible cable with drive and detect conductors determines media guide position through selective electrical connections.

A winding device adjusts a middle shaft position to control film tension during rewinding operations.

A sheet discharge device adjusts tray height using top-surface detection to manage stacking.

Moving-amount detecting units measure displacement across the width direction, preventing damage from rotation or deformation when sheets are stapled.

A delivery device holding device secures the topmost sheet during transfer to prevent lifting or damage.

An adjustable tray uses a pivoting second board and movable adjustment component to tilt at distinct angles, preventing paper jamming during scanning.

Turning bowls merge adjacent sheets horizontally without 90-degree deflections, reducing system space requirements and eliminating complex adjustments.

Segmented cartridge support and locking mechanisms resolve the height-versus-access contradiction, allowing jam clearance without increasing device footprint.

An edge guide with dual protrusions and a central handle distributes rotation moments to prevent inclining during unlocking.

A sheet processing apparatus positions sheets at specific process locations to ensure precise alignment during conveyance.

Forward rotation force exceeds second roller pair resistance to discharge jammed sheets during return processing.

Variable suction strength flattens curled sheets without wrinkles, ensuring stable conveyance through the printer.

A sheet processing stacker sorts ejected articles by controlling belt conveyor speeds and stopping ejection operations.

A media sheet router redirects sheets using angled turning elements and transfer belts to maintain orientation.

Control circuitry folds stored sheets upon detecting upstream jams, reducing sheet length for easier removal from the stacker.

A sheet material separator uses a monitoring device to detect loose sheets in the feed area.

Variable speed control accelerates sheet transport after electrostatic discharge completes, resolving sticking issues caused by insufficient charge removal.

A semi-active retard feeder uses a hysteresis clutch and Hall Effect sensor to monitor roll motion.

A sheet tray uses interlocked guides and an operation mechanism to allow left- or right-handed users to position the guides easily.

Open zones in the transport belt uncover suction holes only where the sheet contacts the plate, reducing wasted air flow and preventing position drift.

A sheet feeder measures reflected light brightness to determine appropriate air blowing amounts.

A feeding apparatus control unit analyzes separation roller rotation speed to determine the position of stuck recording material.

A guide fence lock mechanism uses a slider block and restriction member to generate friction force for secure positioning.

A sheet stacking apparatus automatically moves its stage to a removal position upon job completion.
