US Patent 7975826 Stacker and card processing apparatus equipped with the stacker

A stacker is composed of a bottom plate, a containing section for storing a plurality of cards by stacking it on the bottom plate and a guiding section for guiding each card entering into the containing section. The guiding section is composed of a sidewall for restricting movement of an entering card when entering into the stacker in a first moving direction and a slanted section for slanting the card against the first moving direction. The slanted card moves in a second moving direction intersecting with the first moving direction at approximately a right angle by the gravitational force.
