Abstract
A card ticket, e.g. for travel, is taken from a stack of blanks (101) which it leaves via two wheels (111, 112) travelling along an axis (113) which does not coincide with the common tangent to two touching wheels (135, 175) which receive the ticket taken from the stack. Thus, once the ticket has completely left the stack unit from which it is taken, it may be reversed partially or totally back out between the receiving wheels (135, 175) without re-engaging the stack unit. The same arrangement can be used at the other end of the internal path to receive a ticket at wheels (163, 203). These wheels can both output a ticket towards a user (arrow F3) and receive a ticket from a user for inspection (arrow F4). Apparatus of this nature can thus create new tickets, inspect unused tickets and return them, and inspect used tickets, cancel them and retain them (arrow F5).
