Function Indicators TRIZ Cases

A stacking tray moves an interrupting plate to block a single optical sensor, enabling precise sheet level monitoring without complex encoders.

An independent skip feed cam controls the sheet feeder grate to enable emergency stops without relying on the synchronized main drive system.

Segmented conveying paths and a waiting portion route sheets directly, eliminating delays caused by longer stapling routes.

A recording apparatus adjusts transport speed to maintain optimal slack levels in roll-shaped media.

An intermediary connecting portion displaces a main body component during attachment, preventing damage to the detection unit caused by misalignment.

A single motor drives multiple rollers via a straddling transmission mechanism, reducing apparatus size and cost while simplifying control.

A post-processor controller adjusts alignment force using medium sensor data to position recording materials accurately.

A medium conveyance device separates bound documents using a controller that switches between non-separation and separation modes.

Segmented feed fingers on a rotating paddle wheel convey book blocks while an air cushion reduces friction, preventing sheet shifting and block damage.

A medium supply system uses edge-side imaging to detect folds in stacked recording media before processing.

A control unit switches conveyance and discharge roller speeds to maintain proper sheet alignment during high-speed image formation.

Strain gauge converts flexible member deflection into electrical signals to adjust fuser temperature, eliminating manual paper weight entry errors.

An upper surface sensor detects the tray level and moves the stack upward automatically, eliminating idle time caused by manual repositioning delays.

A document tray rotates to adjust its inclination angle based on discharge tray status.

Rotating a parallel flat plate refracts the detection beam to adjust height, resolving positional displacement issues in inkjet recording apparatuses.

A sheet conveying device uses segmented suction and electrostatic zones to hold paper securely on a moving belt.

Reversing the drive shaft positions a color reference member at an optimal angle, resolving light source unevenness and sensor sensitivity variations.

Pack dispatching arrangement alternates between bulk and small pack modes, resolving the contradiction between production efficiency and system complexity.

An automated adjustment mechanism shifts the gripper entry range based on detected sheet thickness, preventing flapping and misalignment during conveyance.

A control unit adjusts sheet conveyance speed based on stacking conditions to manage heat dissipation.

A central controller dynamically adjusts feeder delivery to form packages with varying printed product counts.

A sheet cassette edge guide mounts via a segmented groove that widens for insertion and narrows for retention.

Comparing signals from two sensors distinguishes actual jams from noise caused by wrinkles or skewing, preventing false shutdowns.

A rotating flap member guides multi-fed sheets to a dedicated storage section, enabling reliable full-load detection through position monitoring.

An integrated stopper and adjustment screw constrain interlocking support portions, eliminating bulky fixing members to shrink device size.

A single holder supports discharge and reversing rollers, reducing component count while preventing deformation under nipping pressure.

A paper size detection module uses a sliding roller to press elastomers against a carrier plate for position sensing.

Flat metal plates secure the shaft to prevent support part deformation under heavy loads, maintaining high accuracy in medium feeding.

A sheet feed device lifts its stacking tray when the cover opens, creating clearance that prevents obstruction during manual sheet supply.
