Abstract

A securing device for axles (2) in office machines, in particular in printers, with axle journals (2c), which axle journals (2c) are furnished with insertion grooves (2d) near their ends and which axles (2) are supported in side plane components (1) against an axial shifting by way of spring elements. An economic and assembly-friendly securing device is provided by having the axle (2), forming a shoulder (2b), and resting on the inside of the side plane component (1), where the axle journal (2c) can be inserted into an about elongatedly shaped opening (4) in the side plane component (1) following to the insertion groove (2d), such that the axle journal diameter (9) of the axle journal (2c) rests in a smaller circular opening (5) of the elongatedly shaped opening (4), where a spring-loaded tension element (10) can be positioned and inserted between the side plane component (1) and the axle journal (2c ) into the insertion groove (2d) passing over the axle journal diameter (9) at the side plane component (1) and where the spring-loaded tension element (10) can be tensioned in the insertion groove (2d) under spring tension crosswise to the axle journal (2c).
