Conveying Record Carriers TRIZ Cases
- Scanning Device Card Blocking Board Alignment Mechanism
A scanning device uses a movable blocking board to align cards with the read line.
- Compact ID Scanner with Sequential Spectrum Illumination
A compact ID scanner uses sequential light spectrum illumination and a single CCD imager to capture both sides of an ID card.
- Hybrid Card Reader Latching Mechanism Wear Reduction
Remote signals enable the latching mechanism only for integrated circuit cards, reducing mechanical wear on the component during magnetic stripe card removal.
- Friction Drive Positioning with Absolute Encoder Feedback
Absolute encoder strip provides continuous position feedback to a closed loop controller, correcting friction drive slip to maintain ±0.4 mm accuracy.
