CROSS-REFERENCE TO RELATED APPLICATION(S) 
       [0001]    This application claims priority to provisional patent application No. 61/562,643 filed Nov. 22, 2011, entitled “Synchronized Media Hanger/Guide”, the contents of which are herein incorporated by reference. 
     
    
     FIELD OF DISCLOSURE 
       [0002]    The present invention relates generally to media hangers utilized in copiers and printers; more specifically, to a media hanger/guide with synchronized support members that hold media therebetween, one of which is foldable to allow insertion of new media without displacing the support member&#39;s position. 
       BACKGROUND 
       [0003]    Printing systems such as copiers, printers, facsimile devices or other systems having a print engine for creating visual images, graphics, texts, etc. on a page or other printable medium typically include various media feeding systems for introducing original image media or printable media into the system. Examples include direct thermal and thermal transfer demand printers. Typically, a thermal transfer printer is a printer which prints on media by melting a coating of ribbon so that it stays affixed to the media on which the print is applied. It contrasts with direct thermal printing where no ribbon is present in the process and an image is created by application of heat to a temperature sensitive media. Typically, thermal transfer printers comprise at least one supply spindle operable for supplying a media web and ribbon, a print station, and a take up spindle. New ribbon and media is fed from the supply spindle along a predetermined media feed path to the print station for printing and then the ribbon is wound up by the take up spindle while the media exits the print station. 
         [0004]    Problems with current printing systems include alignment and compression issues along the media feed path, which may result in faulty or defective printing. Media hangers and/or guides, also referred to as media storage assemblies, are utilized in such printers and associated devices so as to retain a supply of media and ribbon and initially guide the media through the predetermined media feed path of the printer. Heretofore, the type of media hanger utilized in printers has been dependent upon the type and size of media utilized. This dependency severely limits the anticipated use of the media hanger, and the printer, to only one media type and size. Undesirably, the lack of versatility and configurability in accommodating varying media types and sizes causes a need for separate printers and media guides to be purchased if printing on various types and sizes media is desired. Additionally, conventional media hangers require the manual movement or manipulation of one support member at a time in order to position a media supply media on or about an assembly. However, such movement may result in the media being off center relative to the media feed path. 
       SUMMARY OF THE INVENTION 
       [0005]    In accordance with the teachings disclosed herein, embodiments related to a media hanger/guide are disclosed. Embodiments of the present invention provide a configurable and adaptable media hanger/guide operable for use within a printing system that may be used in conjunction with a variety of media types and sizes. Embodiments of the present invention maintain media positioned thereon in a centered position relative to the media feed path by providing synchronized movement of support members located on both sides of the media in either an expansive or compressive manner. Embodiments of the present invention also provide an integral media sensor configured to detect media level or media presence such that an alert to a user may be triggered or displayed. 
         [0006]    In an exemplary embodiment, the media hanger/guide includes a media hub having a top surface and a channel extending through a portion of the top surface. The media hanger/guide further includes two mounting brackets, each having an elongated member and each elongated member having a plurality of teeth located thereon. The mounting brackets can be positioned in the channel. Each mounting bracket includes a support member connected thereto. At least a portion of each support member is preferably located outside of the channel of the media hub. The support members can be adapted for lateral movement along the channel of the media hub relative to the top surface of the media hub. The media hanger/guide further includes two gears positioned in the channel. The first gear is preferably in operable connection with the teeth of one of the mounting bracket&#39;s elongated members.

         [0007]    In an additional exemplary embodiment, the media hanger/guide further includes a lock movably secured to the media hub. The lock is preferably movable between a first position and a second position. The first position of the lock preferably engages the second mounting bracket and thereby secures the first support member and the second support member in a predetermined position. The second position can disengage the second mounting bracket and thereby allow lateral movement of the first support member and the second support member along the media hub relative to the media hub&#39;s top surface. 
         [0008]    In another exemplary embodiment, the media hanger/guide further includes a mounting bracket cover positioned within the channel of the media hub. The mounting bracket cover can partially enclose the mounting brackets and the gears within the media hub. The mounting bracket can have elongated apertures positioned to allow lateral movement of the support members. 
         [0009]    In another exemplary embodiment, the first support member is allowed to move between a position near a first end of the media hub and a position near the lengthwise-center of the media hub. The second support member is allowed to move between a position near a second end of the media hub, located opposite the first end of the media hub, and a position near the lengthwise-center of the media hub. The relative positions near the lengthwise-center of the media hub can be spaced apart. 
         [0010]    In an additional exemplary embodiment, the media hanger/guide further includes one or more sensors located on one or both of the support members. 
         [0011]    In a further exemplary embodiment, one or both of the support members can be foldable from a first position to a second position in relation to the media hub. The first position can be a position substantially perpendicular to the media hub. The second position can be a position substantially parallel to the media hub. 
         [0012]    In a still further exemplary embodiment, the media hanger/guide includes mounting brackets, each having an elongated member wherein each elongated member includes a plurality of teeth located thereon. Each mounting bracket can also have a support member connected thereto. The media hanger/guide can further include two gears. The first gear can be in operable connection with the teeth of one of the mounting bracket&#39;s elongated members. The second gear is in operable connection with the teeth of the other mounting bracket&#39;s elongated members. The gears are preferably also in operable connection with each other. 
         [0013]    In an additional exemplary embodiment, the media hanger/guide further includes one or more sensors located on one or both of the support members. 
         [0014]    In a further exemplary embodiment, one or both of the support members can be foldable from a first position to a second position in relation to the mounting brackets. The first position can be a position substantially perpendicular to the mounting brackets. The second position can be a position substantially parallel to the mounting brackets.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0023]    The present invention will now be described more fully hereinafter with reference to the accompanying drawings in which exemplary embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These exemplary embodiments are provided so that this disclosure will be both thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Further, as used in the description herein and throughout the claims that follow, the meaning of “a”, “an”, and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise. In certain instances, well-known methods, procedures, components, and circuits have not been described in detail. 
         [0024]    Referring now to the drawings,  FIG. 1  illustrates an exemplary embodiment of the present invention in an expanded or open position and  FIG. 2  illustrates an exemplary embodiment of the present invention in a compressed or closed position, wherein media may be inserted thereon. As shown, media hanger/guide  100 , adapted for use within a printing system (not shown), can include media hub  102 . In exemplary embodiments, media hub  102  can be provided with at least one securing screw (not shown) for mounting media hub  102  to the printing system (not shown). Media hanger/guide  100  can further include channel  105  extending along top surface  108  of media hub  102 . Mounting bracket cover  109  having apertures  117   a,    117   b  can be located within channel  105 . 
         [0025]    Media hanger/guide  100  can further include first support member  103 , and second support member  104 . Support members  103  and  104  can be adapted for lateral movement along channel  105 . Apertures  117   a,    117   b  can direct lateral movement of first support member  103  and second support member  104 . 
         [0026]    One or more media sensors  106   a,   106   b  (see  FIG. 4 ) can be present in media hanger/guide  100 . Media sensor(s)  106   a  and/or  106   b  can be provided and located on first support member  103  and/or second support member  104 . Media sensors  106   a,    106   b  can be adapted to detect the presence and/or absence of media in synchronized media hanger/guide  100  and can be in communication with control circuitry (not shown). Media sensors  106   a,    106   b  can be optical sensors, mechanical sensors, or another suitable sensor as is known in the art. The presence or absence of media, as determined by media sensors  106   a,    106   b,  may influence certain functions of the print system (not shown) printer according to programming within the control circuitry (not shown). Media sensors  106   a,    106   b  can be used with roll media, although use of the sensors in conjunction with folded media or other types of media is also contemplated. 
         [0027]    According to aspects of the present invention, at least one optional lock  107  can be movably secured to media hub  102  for locking first support member  103  and/or second support member  104  in a predetermined position along channel  105  of media hub  102 . In an exemplary embodiment, lock  107  can be a cam locking handle; however, although shown in the figures as a locking handle, lock  107  may be of any type of lock capable of maintaining the position of support member  103 ,  104 . Lock  107  can be utilized to hold media hanger/guide  100  in an open position as shown in  FIG. 1 , in a closed position as shown in  FIG. 2 , or any position therebetween. 
         [0028]    Lock  107  can allow first support member  103  and first support member  104  to be maintained in various positions along channel  105  of media hub  102 . Such positioning may be desirable when using fan-fold media. Lock  107  can be rotated between a first position and a second position. Positioning lock  107  in a first position can secure first support member  103  and second support member  104  in predetermined positions and positioning lock  107  in a second position can allow lateral movement of first support member  103  and second support member  104  along channel  105  of media hub  102 . 
         [0029]    Referring now to  FIG. 3 , a perspective view of a portion of an exemplary embodiment of media hanger/guide  100  is shown installed in partially viewable print station  305  with media  301  secured thereon. Media  301  can be positioned on media hub  102  such that media  301  is located between first support member  103  (not shown) and second support member  104 . With lock  107  disengaged, the positions of first support member  103  and first support member  104  can be adjusted to the size of media  301 . First support member  103  and second support member  104  can be adjusted simultaneously and synchronously so as to center the media within the hanger/guide. Simultaneous and synchronous adjustment will be discussed in further detail below. 
         [0030]    Media hanger/guide  100  can be utilized in conjunction with a variety of media types and sizes. Although not shown, embodiments of the present invention can be used to guide and house media of various forms, including, but not limited to, rolled media and fan-fold media. 
         [0031]    Referring now to  FIG. 4 , a perspective view of an exemplary embodiment of media hanger/guide  100  is shown in a loading position. Second support member  104  can be foldable about pivot point  410 . Although pivot point  410  is illustrated as being located at the base of second support member  104 , other locations of pivot point  410  are envisioned. The degree in which second support member  104  folds can vary from zero degree to 360 degrees. Detents (not shown) can be provided to assist in snapping second support member  104  into a position and maintain second support member  104  in such position. Although  FIG. 3  depicts second support member  104  as foldable, in addition or in the alternative, first support member  103  can also be foldable. 
         [0032]    Providing one or more foldable support members can allow for loading of media having the same size as previously loaded media without having to move the support members. By way of non-limiting example, if first support member  103  and second support member  104  were previously adapted to fit a certain size media, then new media of the same size can be loaded without linear movement of the support members along channel  105 . If pivot point  410  is located at the base of second support member  104  and if second support member  104  is foldable by approximately ninety degrees from a substantially vertical start position, the new media roll can be loaded onto media hub  102 . 
         [0033]    Now referring to  FIG. 5 , a cross-sectional view of an exemplary embodiment of support member mounting brackets of media hanger/guide  100  is shown. First support member  103  and second support member  104  can be secured to, inserted into, connectable to, or otherwise attached to first mounting bracket  512   a  and second mounting bracket  512   b,  respectively. First mounting bracket  512   a  and second mounting bracket  512   b  can be sized and shaped so as to permit first support member  103  and second support member  104 , respectively, to movably slide along apertures  117   a,    117   b  when lock  107  is disengaged and directional pressure is applied to either support member. Movement of first mounting bracket  512   a  and second mounting bracket  512   b  can be synchronized with one another via varying means, including, but not limited to, a rack and dual pinion system or other centering system as is known in the art. 
         [0034]    In an exemplary embodiment, first mounting bracket  512   a  and second mounting bracket  512   b  are synchronized utilizing a rack and pinion system  500 . First mounting bracket  512   a  can comprise first mount  513   a  and first elongated member  514   a  having plurality of teeth  515   a  thereon. Similarly, second mounting bracket  512   b  can comprise second mount  513   b  and second elongated member  514   b  having a plurality of teeth  515   b  thereon. 
         [0035]    First gear  516   a  and second gear  516   b  can engage teeth  515   a  and teeth  515   b,  respectively, such that when rotational motion is applied to gear first gear  516   a  and second gear  516   b,  first elongated member  514   a  and second elongated member  514   b  move. First gear  516   a  and second gear  516   b  can be positioned such that they can engage one another. In such a manner, when one of first support member  103  or first support member  104  is adjusted, a rotational motion is initially applied to the respective first gear  516   a  or second gear  516   b,  causing rotational movement of the respective opposite gear  516   b  or  516   a  and movement of both first elongated member  514   a  and second elongated member  514   b  occurs. Adjustment of first support member  103  and second support member  104  can be manual and/or automatic. 
         [0036]    First mount  513   a  and second mount  513   b  can be used for connecting first support member  103  and second support member  104 , respectively, thereto. This support member mounting bracket system can allow simultaneous and synchronous adjustment of first support member  103  and second support member  104 . For example, when one support member is adjusted, the other support member is oppositely adjusted in a simultaneous manner. 
         [0037]    The following is an exemplary use of an embodiment of synchronized media hanger/guide  100 . If second support member  104  is in an upright position, second support member  104  can be folded such that it is substantially parallel to media hub  102 . Media roll  301  (or any other type of media) can be loaded on media hub  102 . Once media roll  301  is loaded, second support member  104  can be positioned such that it is substantially perpendicular to media hub  102 . First support member  103  and second support member  104  can be manipulated so as to move first support member  103  and second support member  104  toward or away from one another along media hub  102  to a desired position. Channel  105  and apertures  117  can provide guidance and/or structural support for the movement of first support member  103  and second support member  104  along media hub  102 . Simultaneous and synchronized movement can allow for media  301  to be centered within media guide/hanger  100 . Lock  107  may be rotated to lock first support member  103  and second support member  104  into position. 
         [0038]    Having now described the invention, the construction, the operation and use of exemplary embodiments thereof, and the advantageous new and useful results obtained thereby, the new and useful constructions, and reasonable mechanical equivalents thereof obvious to those skilled in the art, are set forth in the appended claims.
