Abstract: A portable cartridge and mounting apparatus includes, within the cartridge, a document separator, a stack follower, a double document restraint, and a three position lock and latch mechanism for selectively locking the cartridge cover and the issue slot. The mounting includes first and second drives for operating the separator and restraint mechanisms to issue individual documents through the issue slot. The mounting and cartridge are keyed to detect that a cartridge containing a predetermined denomination is properly mounted with the issue slot open to enable the drive mechanisms. A sensor is provided to detect a cash out condition to inhibit operation of the drives.
