Spreading and isolation of stacked cards using vacuum hole array

This report describes a new mechanism that performs the spreading and isolation of stacked cards using an array of vacuum holes. The separation and isolation of cards including tickets and bills are key operations in the backyard of stations and banks. Operations must be performed robustly against oil or water attached on cards in a small operational area. This report introduces a simple mechanical system that can perform the spreading and isolation of stacked cards robustly.
