Abstract:

A tape cartridge access door includes a body having two flanges and a pseudo-head therebetween. In the open position, the access door permits a tape head to be mated with the tape in the cartridge. In the closed position, the body and flanges close openings in three adjacent walls of the tape cartridge. Also in the closed position, the pseudo-head occupies the space otherwise occupied by the tape head when the tape head is mated with the tape. The pseudo-head thus prevents the tape from being drawn taut straight when the access door is closed. The access door may pivot or slide between the open position and the closed position.

Abstract:

An automatic cartridge feeder includes a magazine slot that receives a cartridge magazine and includes a priority slot that directly receives single cartridges. The automatic cartridge feeder can receive a cartridge through the priority slot regardless of the condition of the cartridge magazine. In an automatic mode, cartridges are taken sequentially from the magazine and are processed. Any cartridge placed in the priority slot by an operator will be processed immediately after any in-progress cartridge processing. In an accumulate mode, cartridges are received through the priority slot for processing and are returned in sequence to an empty cartridge magazine.
