Abstract

A docking station for a removable printer mechanism is provided, together with methods for providing a removable printer mechanism. The docking station may have a base with parallel side arms adapted to be fixed to an interior of a printer housing. Side walls may extend from each of the parallel side arms. The side walls may be adapted to guide the printer mechanism into a docked position in the printer and to removably fix the printer mechanism in the docked position. A bridge element may extend between the parallel side arms at a rear of the base. A clamping element may be fixed to the bridge element and be adapted to hold a printer-side cable connector in position to accept a corresponding cable connector of the printer mechanism. The printer mechanism may easily be slid into and out of the docking station for repair or replacement.

DETAILED DESCRIPTION

(9) The ensuing detailed description provides exemplary embodiments only, and is not intended to limit the scope, applicability, or configuration of the invention. Rather, the ensuing detailed description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing an embodiment of the invention. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims.

(10) An example embodiment of a docking station 10 for a removable printer mechanism in accordance with the present invention is shown in FIG. 1. FIGS. 2 and 3 show the docking station 10 of FIG. 1 installed in a printer housing 12 (note only a partial assembly of the interior of the printer housing is shown for clarity in FIGS. 2 and 3). In FIG. 2, the printer mechanism 14 is shown in the removed position, and in FIG. 3 the printer mechanism 14 is shown in a docked position in the docking station 10. FIGS. 4 and 5 show opposite sides of an example embodiment of a printer mechanism 14. Although FIGS. 2 and 3 show a printer housing 12 configured with two docking stations 10 to accept two printer mechanisms 14, it should be appreciated that the present invention can be implemented in a printer having only a single docking station 10 and a single printer mechanism 14.

(11) The docking station 10 may comprise a base 16 with parallel side arms 18 adapted to be fixed to an interior of a printer housing 12. Side walls 20 may extend from each of the parallel side arms 18. The side walls 20 may be adapted to guide the printer mechanism 14 into a docked position (shown in FIG. 3) in the printer and to removably fix the printer mechanism 14 in the docked position. A bridge element 22 may extend between the parallel side arms 18 at a rear side of the base 16. As shown in FIG. 6, a clamping element 24 may be fixed to the bridge element 22 and be adapted to receive a printer-side cable connector 26. The clamping element 24 may hold the printer-side cable connector 26 in position to accept a corresponding cable connector 28 (shown in FIG. 4) of the printer mechanism 14. The clamping element 24 may be a clamp for an FCC cable connector of an FCC cable 25, as shown in the Figures. However, the present invention may be easily modified to use other types of clamps for other types of cable connectors, the important aspect being the positioning of the printer-side cable connector at a location (height and position between side walls 20) to automatically mate with the corresponding printer mechanism cable connector upon insertion of the printer mechanism 14 into the docking station 10.

(12) A gap 30 may be provided between the bridge element 22 and a floor 32 of the printer housing 12 when the docking station 10 is fixed in the interior of the printer. The gap 30 between the bridge element 22 and the floor 32 of the printer housing 12 may be adapted to accept a tongue 34 of the printer mechanism 14. The tongue 34 of the printer mechanism may be provided to assist in guidance of the printer mechanism 14 into the docked position in the docking station 10. In particular, the tongue 34 may slide into the gap 30 under the bridge element 22 when the printer mechanism 14 is inserted into the docking station 10.

(13) The side walls 20 may each be provided with a slot 36 for accepting alignment studs 38 of the printer mechanism (see FIGS. 4 and 5). As shown in FIG. 7, the alignment studs 38 may snap into detents 40 provided in the slots 36 to removably fix the printer mechanism 14 in the docking station 10. A connection between the printer-side cable connector 26 and the corresponding cable connector 28 of the printer mechanism 14 may be established as the alignment studs 38 snap into the detents 40. One of the alignment studs 38 may comprise a mounting location for a transmission gear 42 of the printer mechanism 14.

(14) The clamping element 24 may removably hold the printer-side cable connector 26 with a snap fit. The clamping element 24 may be a plastic clamp which is flexibly mounted to the bridge element 22 by a snap fit and/or screws.

(15) With the docking station 10 of the present invention, the printer mechanism 14 can be easily removed from or installed in the printer by a user with a one hand and without the use of tools. Installation or insertion of the printer mechanism 14 is accomplished by opening a front door or cover of the printer and simply sliding the printer mechanism 14 into the docking station 10. The side walls 20 of the docking station 10 align the printer mechanism cable connector 28 with the printer-side cable connection 26. The printer mechanism 14 snaps into place in the docking station 10 as the electrical connection between connectors 26 and 28 is made. Removal of the printer mechanism 14 is simply the reverse of the installation procedure. The printer mechanism 14 is simply pulled out of the docking station 10 with sufficient force to overcome a holding force of the detents 40 which retain the alignment studs 38 in the slots 36 of the side walls 20. This ease of insertion and removal allows the printer mechanism 14 to be removed for repair without returning the entire printer assembly, or to be easily replaced.

(16) The present invention also encompasses methods for providing a removable printer mechanism. In one example embodiment of such a method in accordance with the present invention, the method may comprise providing a docking station 10 for the printer mechanism 14. The docking station 10 may comprise a base 16 with parallel side arms 18 adapted to be fixed to an interior of a printer housing 12, side walls 20 which may extend from each of the parallel side arms 18, the side walls 20 being adapted to guide a printer mechanism 14 into a docked position in the printer and to removably fix the printer mechanism 14 in the docked position, a bridge element 22 which may extend between the parallel side arms 18 at a rear side of the base 16, and a clamping element 24 which may be fixed to the bridge element 22 and adapted to receive a printer-side cable connector 26. The clamping element 24 may hold the printer-side cable connector 26 in position to accept a corresponding cable connector 28 of the printer mechanism 14. The method may further comprise providing a removable printer mechanism 14 adapted to be guided by the side walls 20 of the docking station 10 into the docked position, removably fixing the printer mechanism 14 in the docking station 10 in the docked position, and establishing a removable connection between the printer-side cable connector 26 and the corresponding cable connector 28 of the printer mechanism 14 when the printer mechanism 14 is in the docked position.

(17) The method may also include additional features discussed above in connection with the various embodiments of the docking station 10.

(18) It should now be appreciated that the present invention provides an advantageous docking station for a removable printer mechanism and methods of providing such a removable printer mechanism.

(19) Although the invention has been described in connection with various illustrated embodiments, numerous modifications and adaptations may be made thereto without departing from the spirit and scope of the invention as set forth in the claims.
