Article Feeders TRIZ Cases
- Cam Mechanism Maintains Roller Pressure Without Power
A cam member presses a separation roller toward a feed roller using a one-way clutch to hold position.
- Paper Feeder Lock Mechanism for Stopper Stability
A locking mechanism engages a claw with an engagement projection to secure the holder, preventing misalignment during non-paper feeding.
- Sheet Guide Member for Curved Transport Path Noise Reduction
A sheet guide member extends into a merging section to manage trailing end flexing forces, reducing striking sounds against transport guides.
- Automatic Document Feeder Multi-Feed Detection Sensor Unit
A multi-feed detection sensor unit uses ultrasonic sensors to separate documents.
- Medium Feeding Device Suppression Unit for Accurate Paper Handling
A medium feeding device uses a suppression unit to maintain paper position during air blowing.
- Detachable Roller Cover for Medium Feeding Device Maintenance
Segmented covers extract independently to widen workspace, preventing scratches during maintenance.
- Rotary Stacking Wheel with Segmented Vanes for Paper Handling
Segmented vanes on a rotary body prevent large banknotes from slipping out while minimizing the apparatus footprint.
- Motor Control Device Field Weakening for High-Speed Torque
A motor control device adjusts excitation current to weaken magnetic flux intensity.
- Medium Feeding Mechanism Velocity Control for Arrival Timing
A medium feeding mechanism adjusts transportation velocity based on paper type to synchronize arrival times at the destination apparatus.
- Feeding Roller Segmentation for Sheet Jamming
Segmenting the driven roller into a smaller contactable portion and a toothed wheel portion reduces entry resistance, preventing sheet jamming and banding.
