Scanning system for size markings on cassettes in copier, printer and similar - includes set of size identification blocks with multiplicity of projections which are fitted on one side of cassette and switching mechanism fitted in copier or printer housing

摘要

The switching mechanism (10) is operated by the set of size identification blocks (2). A switch (5) is operated by the switching mechanism (10). The switching mechanism has a number of individually operable switches (10a) on a common carrier part (10b) using a joint (10c). Each operable switch (10a) is connected rotationally with the carrier part (10b). The common carrier part (10b) and each adjusting finger (10a) are connected with each other in one piece to form an integral component of polypropylene, across the joint (10c). ADVANTAGE - Faulty deformation of lever or adjuster can be prevented, without utilisation of dearer or complicated switching mechanism.
