ABSTRACT:
A plurality of micro medium feed mechanisms are provided at different locations in a printer and are all driven by a single step motor through a plurality of clutches and are selectively capable of feeding several different types of mediums, e.g., a sheet medium, a card medium or a rolled medium, i.e., feeding each such medium independently of the another presented via different inlets to the printer for each different type of medium. The step motor, therefore, functions as the sole driving source for a multiple medium handling type printer thereby providing a less expensive micro printer which is capable of incrementally feeding multiple different kinds of medium types in the same printer wherein printing can be accomplished from the very top edge to the very bottom edge of the fed medium due to the particular locations of the micro medium feed mechanisms in the micro printer. Also, a micro medium feed mechanism provided in at least one medium feed location of the printer is capable of selectively feeding at least one type of medium in predetermined incremental amounts in stepped values less than 1 mm.
