Printers have traditionally been used for printing on a variety of media, from standard paper stock to labels and articles. Among these articles are optical data storage disks (commonly referred to as compact disks or CDs). Optical data storage disks include a layer which may be read or written on by a laser of an optical drive system. Formats of optical data storage disks include, for example, compact disk (CD) media, CD-recordable (CD-R) media, CD-read only memory (CD-ROM) media, CD-rewritable (CD-RW) media, digital versatile disk or digital video disk (DVD) media, DVD-random access memory (DVD-RAM) media, and other types of rewritable optical media, such as magneto-optical (MO) disks and phase-change optical disks.
Optical data storage disks are often provided with a printable surface opposite the side from which data is recorded and retrieved. As disk-shaped media, a tray or carrier is often used to hold such disks for positioning of the disks in a printer to facilitate printing on the printable surface. Because this tray or carrier is generally thicker than standard paper stock, consideration should be given to the manner in which the tray is fed into the printer. Existing solutions for feeding such a tray or carrier into a printer have often been expensive and complex, have resulted in damage to the printer and/or the tray or carrier itself, or have resulted in stalling of the tray or carrier within the printer.
For these and other reasons, a need exists for the present invention.
In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments of the present invention can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
In one embodiment, carrier 30 supports a media 40 for printing on media 40 by printing device 20 when carrier 30 (with media 40) is inserted into or positioned in printing device 20. In one embodiment, media 40 is a circular or disk-shaped media.
In one exemplary embodiment, media 40 includes an optical data storage disk. As an optical data storage disk, media 40 may include, for example, a compact disk (CD) media, a CD-recordable (CD-R) media, a CD-read only memory (CD-ROM) media, a CD-rewriteable (CD-RW) media, a digital versatile disk or digital video disk (DVD) media, a DVD-random access memory (DVD-RAM) media, or any other type of writeable optical media, such as a magneto-optical (MO) disk or phase-change optical disk.
In one embodiment, media 40 includes a circular area 42 having a central bore or opening 44 formed therein. In one embodiment, opening 44 is sized to accommodate a drive pin or other engagement feature of an optical disk drive (not shown). In one embodiment, media 40 includes a layer which may be read or written on by a recording head.
In one embodiment, circular area 42 of media 40 provides a printable area for media 40. In one embodiment, media 40 is supported by carrier 30 such that carrier 30 and media 40 are inserted into or positioned in printing device 20, as described below, for printing on media 40 including, more specifically, circular area 42 of media 40 by printing device 20. As such, printing device 20 prints graphics or images directly on media 40.
In one embodiment, carrier 130 in generally rectangular in shape and includes a longitudinal axis 132. As such, carrier 130 includes opposite sides 134 and 135 oriented substantially parallel with longitudinal axis 132, and includes opposite ends 136 and 137 extended between opposite sides 134 and 135. In one embodiment, longitudinal axis 132 coincides with an axis of insertion of carrier 130 into printing device 20.
In one embodiment, support portion 140 of carrier 130 supports media 40 (
In one embodiment, recess 142 is circular in shape so as to accommodate media 40 as disk-shaped media. In one embodiment, a depth of recess 142 is substantially equal to a thickness of media 40 such that a surface of circular area 42 of media 40 and a surface 144 of support portion 140 form a substantially uniform or planar surface. Support portion 140 may also include additional features to accommodate and/or facilitate supporting of media 40 for printing on media 40.
In one embodiment, tapered portion 150 of carrier 130 is provided at an end 146 of support portion 140, and includes a surface 152 contiguous with surface 144 of support portion 140. As such, tapered portion 150 forms a leading portion of carrier 130 for insertion or positioning of carrier 130 in printing device 20 (
In one embodiment, tapered portion 150 has a leading edge 154 and tapers from support portion 140 in a direction toward leading edge 154. As such, tapered portion 150 forms a ramp or wedge between leading edge 154 and surface 144 of support portion 140.
In one embodiment, leading edge 154 of tapered portion 150 is angled between insertion tabs 160 and sides 134 and 135 of carrier 130. More specifically, in one embodiment, a portion 156 of leading edge 154 extended between insertion tab 162 and side 134 of carrier 130 is oriented at an angle 157, and a portion 158 of leading edge 154 extended between insertion tab 164 and side 135 of carrier 130 is oriented at an angle 159. In one exemplary embodiment, an absolute value of angle 157 is substantially equal to an absolute value of angle 159.
In one embodiment, insertion tabs 160 of carrier 130 protrude from surface 152 of tapered portion 150, and extend beyond leading edge 154 of tapered portion 150. In addition, insertion tabs 160 follow the ramp or wedge shape of tapered portion 150. Accordingly, as described below, insertion tabs 160 become an initial point of contact for carrier 130 during insertion or positioning of carrier 130 in printing device 20 (
In one embodiment, carrier 130 includes a pair of spaced insertion tabs 162 and 164. As such, insertion tabs 162 and 164 facilitate positioning of carrier 130 in printing device 20, as described below. In one embodiment, insertion tabs 162 and 164 are of differing widths such that insertion tab 162 is wider than insertion tab 164. Although insertion tab 162 is illustrated and described as being wider than insertion tab 164, insertion tab 164 may be wider than insertion tab 162. In addition, although illustrated and described as being of differing widths, insertion tabs 162 and 164 may be of the same width.
In one embodiment, ramps 170 are provided on both sides of insertion tabs 160. More specifically, ramps 172 are provided on opposite sides of insertion tab 162, and ramps 174 are provided on opposite sides of insertion tab 164. As such, ramps 170 extend between and provide a transition between insertion tabs 160 and surface 152 of tapered portion 150. Accordingly, as described below, ramps 170 assist during insertion or positioning of carrier 130 in printing device 20 (
Media guides 24 are positioned adjacent or opposed to feed roller 22 such that a nip 29 is formed between feed roller 22 and media guides 24, including, more specifically, between feed roller 22 and pinch rollers 26 of media guides 24. As such, media inserted into or positioned in nip 29 is fed into printing device 20 for printing thereon. Although four media guides 24 each including two pinch rollers 26 are illustrated, the number of media guides 24 and/or the number of pinch rollers 26 may vary.
In one embodiment, insertion tabs 160 are aligned with one or more media guides 24 when carrier 130 is inserted or positioned in printing device 20. More specifically, in one embodiment, each insertion tab 160 is aligned with a side 28 of one or more media guides 24. In one embodiment, for example, insertion tab 162 is aligned with side 281 of media guide 241, and insertion tab 164 is aligned with sides 282 and 283 of adjacent media guides 242 and 243.
In one embodiment, since insertion tabs 160 protrude from surface 152 of tapered portion 150 and extend beyond leading edge 154 of tapered portion 150, when carrier 130 is inserted or positioned in printing device 20, insertion tabs 160 contact media guides 24 before leading edge 154 of tapered portion 150 contacts media guides 24. Insertion tabs 160, therefore, contact media guides 24 before leading edge 154 contacts pinch rollers 26 and reaches nip 29. As such, insertion tabs 160 lift media guides 24, including, more specifically, sides 28 of media guides 24, as carrier 130 is inserted or positioned in printing device 20. Accordingly, after insertion tabs 160 are fed into nip 29, insertion tabs 160 lift one side of respective media guides 24 such that pinch rollers 26 of media guides 24 roll up tapered portion 150 and onto surface 144 of support portion 140.
In one embodiment, as insertion tabs 160 lift media guides 24, media guides 24 and, more specifically, pinch rollers 26 of media guides 24 follow tapered portion 150. In addition, ramps 170 provided on the sides of insertion tabs 160 assist in guiding media guides 24 up tapered portion 150 to support portion 140.
In one embodiment, as insertion tabs 160 lift media guides 24, carrier 130 is fed into printing device 20 by feed roller 22. As such, carrier 130 passes between feed roller 22 and pinch rollers 26 of media guides 24. In one embodiment, while and/or after a portion of carrier 130 passes between feed roller 22 and media guides 24, printing device 24 prints on media 40 (
With tapered portion 150 provided at a leading edge of carrier 130 and by including insertion tabs 160 at the leading edge, insertion tabs 160 serve as an initial surface to be captured in nip 29 as carrier 130 is fed between feed roller 22 and media guides 24. In addition, insertion tabs 160 also serve to lift media guides 24 and, more specifically, pinch rollers 26 of media guides 24, onto carrier 130, including, more specifically, support portion 140 of carrier 130, by wedging insertion tabs 160 and tapered portion 150 of carrier 130 under sides 28 of media guides 24. By wedging insertion tabs 160 under sides 28 of media guides 24, media guides 24 can be gradually lifted onto carrier 130. As such, carrier 130 can be fed into printing device 20 for printing on media 40 as supported by carrier 130.
