FIG. 1 illustrates a perspective view of an example imaging system capable of implementing operations of the example devices. In the illustrated example, animaging system 100 is in the form of a point-of-sale (POS) system, having aworkstation 102 with a workstation surface (e.g., a counter) 104 and a bi-optical (also referred to as “bi-optic”)barcode reader 106. - In the illustrated example, also shown in
FIG. 2 , thebarcode reader 106 includes an upper housing 114 (also referred to as an upper portion or tower portion) and a lower housing 112 (also referred to as a lower portion or platter portion). Theupper housing 114 is characterized by an opticallytransmissive window 120 positioned there along a generally vertical plane and a horizontally extending field of view(s) which passes through thewindow 120. Thelower housing 112 is characterized by aweigh platter 111 that includes an opticallytransmissive window 118 positioned there along a generally horizontal plane and a vertically extending field of view(s) which passes through thewindow 118. Referring for a moment toFIG. 3 , in some embodiments the weigh platter may be comprised of two primary sections, ahorizontal section 140 and avertical section 142. However, this configuration is not essential, and in some cases thevertical section 142 may be omitted, providing only thehorizontal section 140. Theweigh platter 111 is a part of a weigh platter assembly that will generally include theweigh platter 111 and a scale configured to measure the weight of an object placed on an example surface of thetop portion 116, or some portion thereof. - In operation, a
user 108 generally passes anitem 122 across a product scanning region of thebarcode reader 106 in a swiping motion in the general direction 107, which in the illustrated example is right-to-left. It should be appreciated that while items may be swiped past thebarcode reader 106 in either direction, items may also be presented into the product scanning region by means other than swiping past the window(s). When theitem 122 comes into the any of the fields of view of the reader, thebarcode 124 on theitem 122 is read and decoded by thebarcode reader 106 and corresponding data is transmitted to a communicatively coupledhost 130. In other instances, items may need to be weighed in order to be added to the ledger of the transaction. In this case, an item is placed on thetop surface 116 of theplatter 111 for thebarcode reader 106 to sense the weight of said item and transmit information associated with this weight to thehost 130. - Referring now to
FIG. 3 , in a preferred configuration, theweigh platter 111 is designed to constrain items in the central region thereof or otherwise away from its lateral edges. This is achieved by providing the platter with a particularly designed structural features as outlined below. To help further understand the various embodiments disclosed herein, references can also be made toFIGS. 4-10 which are various embodiments of theweigh platter 111 taken alongsection line 143, looking away from thevertical section 142. - In the example shown in
FIG. 3 , theweigh platter 111 includes acentral region 144 extending in a transverse plane. Thecentral region 144 including awindow 118 configured to permit light to pass therethrough. This allows light to pass to the internal imaging components for proper barcode reading. Thewindow 118 normally has atransparent medium 146 that has atop surface 148 extending parallel to the transverse plane of the central region. In a prefer embodiment, this medium is a sapphire glass sheet measuring approximately 4 inches by 6 inches, though other sizes are within the scope of embodiments disclosed herein. While sapphire glass may be preferred due to its scratch-resistant properties, other transparent media may also be used. - Surrounding the
central region 144 are aproximal edge region 148, a firstlateral edge region 150, a secondlateral edge region 152, and adistal edge region 154. As is visible inFIG. 2 , when theplatter 111 is installed on thebi-optic reader 106, theproximal edge region 148 adjacent to theupper housing portion 114 and includes aproximal edge 156. In other embodiments where the barcode reader may be, for example, a slot scanner, and may not include theupper housing portion 114, the proximal else 156 may be viewed extending substantially along the swiping direction of an item being swiped past the reader. - The first
lateral edge region 150 extends non-parallel to theproximal edge 156 and has a firstlateral edge 158. In a preferred embodiment, the firstlateral edge region 150 is positioned along one side of thewindow 118, and therefore thecentral region 144. The secondlateral edge region 152 is provided opposite the firstlateral edge region 150 and, like the firstlateral edge region 150, extends non-parallel to theproximal edge 156 and has its own, secondlateral edge 160. Also, the secondlateral edge region 152 is positioned along another (opposite) side of thewindow 118. The remaining region is referred to as thedistal edge region 154. It is positioned opposite theproximal edge region 148, extending non-parallel to the first and secondlateral edges distal edge 162. - To help retain the item placed on the platter within the confines thereof, the
patter 111 is designed in a way where each of the firstlateral edge 158 and the secondlateral edge 160 extends at least 1 mm above the transverse plane. In a preferred embodiment, both of theedges - In some embodiments it is desirable to install the

In this instance, it should be appreciated that the transverse plane, as defined by thecentral region 144, will be below the counter/surface 104. In other instances, thelateral edges surface 104. However, in this configuration items being dragged between the counter and the platter may bump, scrape, or otherwise impact theedges - Referring to the embodiment of
FIGS. 3-6 , and particularlyFIGS. 4-6 , the firstlateral edge region 150 includes a first-lateral-edge-region surface 164 that extends along at least some portion of the firstlateral edge 158 and the secondlateral edge region 152 includes a second-lateral-edge-region surface 166 that extends along at least some portion of the secondlateral edge 160. It should be appreciated that thesesurfaces region surface 164 and the second-lateral-edge-region surface 166 is non-parallel relative to the transverse plane. This can be illustratively discerned with reference to the drawings where the illustrations ofFIGS. 4 and 6 show eachsurface FIG. 4 having thesurfaces central region 144 before thewindow 118 and the embodiment ofFIG. 6 having thesurfaces central region 144 at the window 118), and the illustration ofFIG. 5 shows eachsurface platter 111. It should be appreciated that while in some embodiments the curved cross-section profile of eachsurface - In some embodiments, at least some portions of the lateral-edge-
region surfaces central region 144 at an angle α of at least 2.5 degrees relative to the transverse plane. In some instances, α may be selected between 2.5 degrees and 10 degrees. In other instances α may be selected between 2.5 degrees and 15 degrees. - In some embodiments, at least some portions of the lateral-edge-
region surfaces surfaces respective surfaces - Referring now to
FIGS. 3 and 7-10 , additional embodiments of theplatter 111 are provided where each of the lateral-edge-region surfaces edge surface 164 having afirst surface 168 and asecond surface 170. Thefirst surface 168 has afirst edge 172 proximal thecentral region 144 and asecond edge 174 distal to thecentral region 144. Thesecond surface 170 has afirst edge 176 proximal thesecond edge 174 of thefirst surface 168 and asecond edge 178 distal to thesecond edge 174 of thefirst surface 168. With such an arrangement, thesecond surface 170 is further away from thecentral region 144 than thefirst surface 168. Conversely on the opposite end of the illustrated embodiment, the lateral-edge surface 166 has afirst surface 180 and asecond surface 182. Thefirst surface 180 has afirst edge 184 proximal thecentral region 144 and asecond edge 186 distal to thecentral region 144. Thesecond surface 182 has afirst edge 188 proximal thesecond edge 186 of thefirst surface 180 and asecond edge 190 distal to thesecond edge 186 of thefirst surface 180. With such an arrangement, thesecond surface 182 is further away from thecentral region 144 than thefirst surface 180. - For clarity, the following discussion is made with reference to only one side of the
platter 111 and only one set of surfaces. However, it should be appreciated that these configurations may be matched or mixed on both sides of theplatter 111 as desired and all such configurations are within the scope of the embodiment(s) described herein. - Having at least some portion of the lateral-edge-
region region 150 be comprised of multipledistinct surfaces FIGS. 7-10 . For example, inFIG. 7 , the arrangement shown therein includes a configuration where, when measured along a direction normal to the transverse plane, thefirst edge 172 of thefirst surface 168 is positioned at the transverse plane, thesecond edge 174 of thefirst surface 168 is positioned at a first height above the transverse plane, and thesecond edge 178 of thesecond surface 170 is positioned as a second height above the transverse plane such that the first height is greater than the second height. This results in the cross-section view of theplatter 111 having a “A ”-like profile with thefirst surface 168 having an upward slope away from thecentral region 144 and thesecond surface 170 having a downward slope away from thecentral region 144. - In an alternate arrangement shown in
FIG. 8 , in the configuration there, when measured along a direction normal to the transverse plane, thefirst edge 172 of thefirst surface 168 is positioned at the transverse plane, thesecond edge 174 of thefirst surface 168 is positioned at a first height above the transverse plane, and thesecond edge 178 of thesecond surface 170 is positioned as a second height above the transverse plane such that the first height is equal to the second height. This results in the cross-section view of theplatter 111 having a “”-like profile with thefirst surface 168 having an upward slope away from thecentral region 144 and thesecond surface 170 being parallel with the transverse plane. - In yet alternate arrangements shown in
FIGS. 9 and 10 , in the configurations there, when measured along a direction normal to the transverse plane, thefirst edge 172 of thefirst surface 168 is positioned at the transverse plane, thesecond edge 174 of thefirst surface 168 is positioned at a first height above the transverse plane, and thesecond edge 178 of thesecond surface 170 is positioned as a second height above the transverse plane such that the first height is less than the second height. In this case the lateral-edge-region region 150 occupied by the first andsecond surfaces FIG. 9 ) or a convex shape (as shown inFIG. 10 ). - In some embodiments, the combined width W2, when measured along the transverse plane, between the
first edge 172 of thefirst surface 168 and thesecond edge 178 of thesecond surface 170 is between 10 mm and 100 mm. - While the above examples have been provided with flat surfaces, it should be appreciated that surfaces with changing slopes are also within the scope of the invention(s) recited herein. As such, surfaces having changing slopes may replace flat surfaces so long as edges of the various surfaces can be joined together.
- Additionally, as shown in
FIG. 11 , in some embodiments edges of various surfaces may be non-parallel to edges of adjacent surfaces or to edges of the same surface. As is shown therein, thefirst surface 168 has afirst edge 172 that is non-parallel with thesecond edge 174 offirst surface 168, thefirst surface 176 of thesecond surface 170, and thesecond edge 178 of thesecond surface 170. Despite this, at least one of the first andsecond surfaces 168, 170 (in the illustrated case surface 168) includes an upward slope away from thecentral region 144 with the final configuration resulting in thelateral edge 158 being higher than the transverse plane. - The embodiments described herein may be particularly useful for instances where liquids find their way onto the platter of barcode readers. It has been recognized that liquids, when spilled on existing platters have a tendency to transition to regions below the platter, causing structural and electrical issues with barcode readers like those described herein. Similarly, matter which may come off produce can similarly pose issues when it finds its way below the platter. Providing the configurations disclosed herein may reduce those instances as these configurations may help retain foreign matter on a top surface of the platter, allowing a user to remove said matter without causing harm to the reader.
