Font cartridge adapter

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring to the FIG.
1, this invention mainly comprises the front shell 11 and rear shell 12.
The front shell 11, open on one side with the interior cavity housing a multiplicity of connectors 6 for the insertions of the font cartridges 3, (referring to the FIG.
2), provides space for the installations of the printed circuit board 7 and circuit board connector 5.
The rear shell 12, open on the side to engage with the open side of the front shell 11, has cartridge insert-end 121 and printer connector-end 122.
The cartridge insert-end 121 has a plurality of channels for accommodating the font cartridges 3; the printer connector-end 122 has one channel for accommodating the circuit board connector 5 when the printer connector-end 122 is plugged in the font cartridge opening 2 of the laser printer 4.
There is a distance between the bottom surface of the cartridge insert-end 121 and top surface of the printer connector-end 122 to avoid the interference between the cartridge insert-end 121 and the laser printer 4 when the printer connector-end 122 is inserted in the opening 2 of the laser printer 4.
In the embodiment of this invention, as shown in FIG.
1, the cartridge insert-end 121 comprises two conduits for the insertion of two font cartridges.
As revealed in FIG.
2, the front shell 11 is open on one side with the upper part of interior cavity housing a multiplicity of connectors 6 for the insertion of the font cartridges 3.
The lower part of the interior cavity near the bottom thereof has a slot for inserting the circuit board connector 5; the pins 51 of the outer-edge of the circuit board connector 5 are plugged in the connector built in the font cartridge opening 2 of the laser printer 4 with the control and data signals being transmitted through the circuit board connector 5.
In between the slot, housing circuit board connector 5, and the connectors 6, there is a printed circuit board 7 for receiving the font selection signals from the laser printer or computer through the circuit board connector 5 and outputting the font selected to circuit board connector 5 through the connector 6 to function for switching and selection purposes
