The invention relates to printers, laminators and other equipment used to produce data bearing identification or financial documents, including plastic cards such as financial (e.g. credit and debit) cards, drivers' licenses, national identification cards, and other similar cards, as well other identification and financial documents, such as passports. In particular, the invention relates to supply items used in such equipment, and to a method of facilitating the loading of the supply items into the equipment.
Identification and financial documents, such as financial (e.g. credit and debit) cards, drivers' licenses, national identification cards, and other cards, as well as passports and the like, are well known. These types of documents are often provided with data, graphics or a combination thereof composed of printed characters and/or images printed onto the documents using a printer. An example of a suitable printer for printing a card is disclosed in U.S. Pat. No. 5,762,431.
Many of these types of printers utilize a print ribbon that provides the ink or dye used to produce the data or graphics. These ribbons need to be replaced as they are used up. However, replacement of the ribbon can be difficult, especially for those who are inexperienced or unfamiliar with the printer. It is not unknown for operators of such printers to incorrectly position the take-up cylinder where the supply cylinder is intended to be positioned, and vice-versa, or to try to position the supply and take-up cylinders at incorrect positions within the printer. In addition, the supply and take-up cylinders can be positioned upside down in the printer so that the ribbon is in the wrong wind direction (e.g. unwound from the supply cylinder and wound onto the take-up cylinder from the bottom of the cylinders rather than from the top).
Similar difficulties exist for other supply items, for example webs that carry laminate patches, cleaning tape or ribbon, holographic overlays, and other exhaustible web materials, used in equipment for producing identification and financial documents.
There is a need for improvements to facilitate loading of supply items into data bearing identification or financial document production equipment.
The invention relates to improvements that facilitate loading of supply items into data bearing identification or financial document production equipment. Supply items include web materials that are used in data bearing identification or financial document production equipment, and which are supplied from a supply cylinder and wound onto a take-up cylinder after use. Examples of supply items include monochromatic and multi-color print ribbons, webs that carry laminate patches, cleaning tape or ribbon, holographic overlays, and other web materials that are used up during use of the equipment. Data bearing identification or financial document production equipment include thermal printers, laminators and combinations thereof, and other equipment that utilize supply items.
In one embodiment, a supply item for data bearing identification or financial document production equipment comprises a supply cylinder, a take-up cylinder, and a web material wound onto the supply cylinder and attachable to the take-up cylinder. The geometry of the take-up cylinder and the supply cylinder are different from each other so that either the take-up cylinder, the supply cylinder, or both, can only be inserted onto the proper spindle. In the preferred embodiment, the geometry of the take-up cylinder is such that it can only be mounted on the take-up spindle.
In another embodiment, a carrier for a supply item used in data bearing identification or financial document production equipment comprises a handle portion having first and second opposite end regions, a supply spindle rotatably mounted to the handle portion at the first end region, a first pin projecting past the end of the supply spindle, a take-up spindle rotatably mounted to the handle portion at the second end region, and a second pin projecting past the end of the take-up spindle. When viewed in an end plan view, the second pin has a geometry (e.g. a difference in size, shape, or both) that is different than a geometry of the first pin. The difference in geometry of the pins is preferably used in conjunction with features on the supply item so that loading of the supply item onto the carrier is made easier.
A method of facilitating loading of a supply item into data bearing identification or financial document production equipment comprises providing a carrier including a supply spindle assembly and a take-up spindle assembly; providing a supply item including a supply cylinder, a take-up cylinder, and a web material wound onto the supply cylinder and having an end thereof attached to the take-up cylinder. The supply cylinder is intended to be disposed on the supply spindle assembly and the take-up cylinder is intended to be disposed on the take-up spindle assembly. At least one of the supply cylinder and the take-up cylinder, and at least one of the supply spindle assembly and the take-up spindle assembly, are designed so that the supply cylinder or the take-up cylinder can only be disposed on the supply spindle assembly or the take-up spindle assembly respectively.
In another embodiment, data bearing identification or financial document production equipment is provided. The equipment includes a housing, a chassis disposed in the housing having first and second side walls defining a supply item receiving area therebetween that is adapted to at least partially receive a carrier having a supply spindle assembly with a supply cylinder received on the supply spindle assembly and a take-up spindle assembly with a take-up cylinder received on the take-up spindle assembly, with a web material wound onto the supply cylinder and having a take-up end thereof that is attached to the take-up cylinder. The first side wall includes first and second support structures for supporting ends of the supply spindle assembly and the take-up spindle assembly, respectively. In addition, the first support structure and the second support structure have different geometries to match different geometries of the supply spindle assembly and the take-up spindle assembly.
For a better understanding of the invention, its advantages and objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying description, in which there is described a preferred embodiment of the invention.
The invention relates to enhancements that facilitate loading of supply items into data bearing identification or financial document production equipment. The enhancements can be provided on the supply item itself, on a carrier that supports the supply item, on the production equipment, or on a combination thereof. Examples of supply items include monochromatic and multi-color print ribbons, webs that carry laminate patches, cleaning tape or ribbon, holographic overlays, and other web materials that are used up during use of the equipment. Data bearing identification or financial document production equipment include thermal printers, laminators and combinations thereof, and other equipment that utilize supply items.
The supply item and the carrier are modified to facilitate loading of the supply item onto the carrier in the proper orientation, and the carrier can be more easily loaded into the production equipment in the correct orientation. A variety of modifications can be utilized to achieve these goals. The preferred modification will be discussed in detail below.
For the sake of convenience, the supply item in the preferred embodiment will be described in relation to a multi-color print ribbon, and the production equipment will be described as a thermal printer that utilizes the supply item. However, it is to be realized that the concepts described herein are applicable to other supply items and other production equipment.
A print ribbon supply item 10 according to the invention is best seen in
The supply cylinder 14 includes first and second ends 20a, 20b and is generally hollow from the first end to the second end. Likewise, the take-up cylinder 18 includes first and second ends 22a, 22b and is generally hollow from the first end to the second end. Preferably, the ends 20a, 20b, 22a, 22b of the cylinders 14, 18 are designed to facilitate loading of the cylinders 14, 18 onto a carrier 24 (to be later described in detail) in the proper orientation, thereby simplifying ribbon replacement. More preferably, a difference in the geometry of the ends of the cylinders 14, 18 is used to achieve the simplified replacement.
With reference to
The difference in the geometry of the openings at the ends 20a, 22a of the cylinders 14, 18 limit how the cylinders 14, 18 can be connected to the carrier 24. While the end of the cylinder 18 is described as having an opening 30 with an area less than the opening at the end of the cylinder 14, it is to be realized that the reduced area opening can be provided on the cylinder 14 rather than on the cylinder 18. In addition, each cylinder could be provided with a reduced area opening, as illustrated in
The carrier 24 forms a structure upon which the cylinders 14, 18 and ribbon 12 can be mounted, and which can then be inserted into the printer. With continued reference to
With reference to
The carrier 24 includes a supply spindle assembly 42 that projects perpendicularly from the end region 34 and a take-up spindle assembly 44 that projects perpendicularly from the end region 36, as best seen in
The spindle assembly 42 comprises a pin 46 and a supply spindle 48 surrounding the pin 46. The length of the spindle 48 and the length of the pin 46 are chosen such that the free end of the pin 46 projects past the end of the spindle 48, as shown in
The spindle 48 is designed to receive the cylinder 14 thereon in such a manner that the cylinder 14 and spindle 48 rotate together with little or no relative rotation therebetween. Rotation between the cylinder 14 and the spindle 48 is prevented by ribs 50 provided on the interior surface of the cylinder and ribs 52 on the outer surface of the spindle 48. Resilient fingers 54 at the end of the spindle 48 snap over the ends of the ribs 50 on the cylinder 14, which are recessed from the end 20a of the cylinder 14, to fasten the cylinder 14 to the spindle 48. This type of connection mechanism between the cylinder 14 and spindle 48 is known in the art.
At the opposite end of the spindle 48, i.e. the end adjacent the handle portion 32, an apertured disk 56 is connected to the spindle for rotation therewith. The disk 50 forms part of a mechanism, well know in the art, to monitor movements of the spindle 48 and thus movements of the supply cylinder 14 to be mounted thereon. The disk 56 is preferably spaced from the end region 34 to provide a space therebetween.
The spindle assembly 44, like the spindle assembly 42, includes a pin 58 and a take-up spindle 60 surrounding the pin 58. The length of the spindle 60 and the length of the pin 58 are chosen such that the free end of the pin 58 projects past the end of the spindle 60, as shown in
The spindle 60 is designed to receive the take-up cylinder 18 thereon in such a manner that the cylinder 18 and spindle 60 rotate together with little or no relative rotation therebetween. The connection between the cylinder 18 and spindle 60 is similar to the connection between the cylinder 14 and spindle 48. At the opposite end of the spindle 60, i.e. the end adjacent the handle portion 32, a gear 62 is connected to the spindle 60 for rotation therewith. The gear 62 is designed to be driven via a suitable driving mechanism to rotate the spindle 60 and thus the cylinder 18 to take-up used ribbon during use of the printer.
As best seen in
In the embodiment illustrated in
Thus, at least the size of the free ends of the pins 46, 58 are different, and, in the illustrated embodiment, both the size and shape of the free ends are different. With this construction, if one attempts to insert the take-up cylinder 18 onto the spindle 48 regardless of the orientation of the ends 22a, 22b of the cylinder, interference between the free end of the pin 46 and the hole 30 prevents such insertion. Likewise, if one attempts to reverse the cylinder 18 and slide the end 22a of the cylinder 18 over the spindle 60, interference between the spindle 60 and the hole 30 prevents insertion in this orientation. Therefore, the only way for the cylinder 18 to be inserted onto the spindle 60, while maintaining proper ribbon orientation, is in the orientation illustrated in
It is to be realized that the free ends of the pins 46, 58 could have similar shapes but different sizes. For example, as illustrated in
In addition, each cylinder 14, 18 could be provided with features to limit insertion thereof onto the respective appropriate spindle. With reference to
The use of differently shaped pins 46″, 58′ also alerts a user that there is a difference in the supply and take-up to make the user more wary when loading the supply item. Other shapes for the ends of the pins and the holes could also be used, for example triangular.
The openings at the ends 20b, 22b in
The take-up cylinder 18 could also be provided with memory means to store information pertaining to the supply item as well as other information. The memory means is preferably read/write memory to permit the reading of data from and the writing of data to, the memory means. The memory means can store information pertaining to the remaining amount of ribbon left on the supply cylinder, with the ribbon remaining information being decremented in the memory means based on print jobs using information provided by the printer controller.
The memory means is preferably a radio frequency identification tag 64 mounted on the wall 26 of the cap 28. A suitable RF receiver/transmitter would be positioned in the printer adjacent to the end of the take-up cylinder 18 for reading data and writing data to the tag 64. The use and operation of RF identification tags is known from U.S. Pat. No. 6,099,178.
The printer 70 comprises a housing 72 having an input/output end 74 including an input station 76 that holds a plurality of cards and that feeds cards into the printer and an output station 78 for receiving printed cards from the printer. The housing 72 includes a pivotable cover 80 that pivots between an open position, shown in
The print ribbon 12 of the supply item 10 is supported by the carrier 24 within the area 82 of the printer 70. The print ribbon 12 is positioned to be heated by resistive dot elements on a thermal print head (not shown) which transfers thermally reactive dye or ink from the ribbon 12 to a card positioned adjacent the print head. The construction and operation of thermal print heads and print ribbons for use with thermal print heads is well known in the art.
The chassis 84 includes first and second side walls 86, 88 which define the receiving area 82 therebetween. The side wall 86 includes first and second support structures that project inward from the wall 86 for supporting the free ends of the pins 46, 58. Each support structure comprises a base section 90a, 90b that is closed at the bottom thereof to support the ends of the pins, for example pins 46, 58, thereon, and a guide section 92 composed of converging wall portions that converge toward the base section 90a, 90b. The converging construction of the guide sections 92 help to guide the respective free ends of the pins 46, 58 into the respective base sections 90a, 90b, thereby making it easier for an operator of the printer to insert the carrier 24 into the printer 70.
