- a cartridge receiving cavity having a cartridge receiving surface portion and a plurality of first switch receiving openings in said cartridge receiving surface portion;
a print assembly comprising a print head and a platen roller, said print head and said platen roller extending into said cavity and at least one being movable relative to the other between a print position in which said print head and platen roller are moved toward engagement with one another and a nonprint position in which said print head and platen roller are moved away from engagement with one another;
a switch assembly comprising a switch mounting member mounted in a fixed position relative to said cartridge receiving surface portion and carrying a plurality of depressible switches each having a plunger member moveable between an extended position and a depressed position wherein said plunger members extend through corresponding said first switch receiving openings, outwardly from said cartridge receiving surface portion and into said cartridge receiving cavity when in their extended positions and do not extend outwardly from said cartridge receiving surface portion when in their depressed position, said cartridge being insertable into said cartridge receiving cavity and comprising;
a cartridge housing having a cartridge surface portion for positioning adjacent to said cartridge receiving surface portion when the cartridge is inserted into the cartridge receiving cavity;
a spool of image receiving tape contained within said housing; and
at least one second switch receiving opening in said cartridge surface portion and aligned with one of said first switch receiving openings to allow the plunger member corresponding to said one first switch receiving opening to extend through said at least one second switch receiving opening to its extended position when said cartridge is inserted into the cartridge receiving cavity, each of said plurality of switches being in one of an on position or off position when its plunger member is in its extended position and being in the other of said on position or said off position when its plunger member is in its depressed position.
