Abstract

The present structure provides a relatively simple latch mechanism which is particularly utilizable for the mounting of a ribbon cartridge in a printer. This simple latch mechanism permits the ribbon to be inserted at an angle into the latch and then pivoted into a position perpendicular to the latch with a minimum clearance between the cartridge post in the receiving hole in the latch. This permits an easy one-handed insertion for the ribbon cartridge into the cartridge-supporting mechanism and for a similar removal of the ribbon cartridge.

Ribbon Cartridge Latch

The present structure provides a relatively simple latch mechanism which is particularly utilizable for the mounting of a ribbon cartridge in a printer. This simple latch mechanism permits the ribbon to be inserted at an angle into the latch and then pivoted into a position perpendicular to the latch with a minimum clearance between the cartridge post in the receiving hole in the latch. This permits an easy one-handed insertion for the ribbon cartridge into the cartridge- supporting mechanism and for a similar removal of the ribbon cartridge.

As shown in Fig. 1, the latch is a single molded piece consisting of three different functional areas: the housing 10, the primary spring section 11 and the secondary spring section 12. The primary and secondary spring sections act independently of each other to allow the cartridge to be inserted as shown in Fig. 2 and removed as shown in Fig.3 while maintaining a minimal distance between the two spring sections and the post of the cartridge which is to be inserted into opening 13. Secondary spring section 12 has an area 14 near its tip which is raised somewhat to ease insertion.

The insertion of a cartridge is shown in Fig. 2, and the removal of a cartridge is shown in Fig. 3.
