An imprinting mechanism (10) includes a sheet tray (22) and comprises a housing (14) and a spring bias device (28) within the housing (14). A sheet stack support (24) is positioned within the housing (14) and in contact with the spring bias (28), the spring bias (28) forcing the sheet stack support (24) towards a first position, the sheet stack support (24) being forced (against the spring bias (28)) to a second position when a stack of sheets is positioned thereon. A pivotally mounted indicator (20) is positioned within the housing (14) and includes first and second arm portions (30, 32), a first portion (30) being in contact with a surface of the sheet stack support (24) and a second portion (32) movable between visible and invisible locations, as viewed by a user. The first portion (30) is movable about the pivot (34) to position the second portion (32) to the visible location when a predetermined size stack of sheets remain in the sheet stack support (24). The indicator (20) is constructed of a single piece of molded plastic and its second portion (32) exhibits greater mass than its first (30) so that no spring or other bias device is required in its operation. <IMAGE> |
