DETAILED DESCRIPTION
A modular workboard thermal printer system, in various embodiments, provides a portable, self-contained device for performing various computing tasks and printing out as a hardcopy the results of such tasks. In broad terms, certain embodiments of the modular workboard thermal printer system include a housing for containing a thermal printer module, a receiving slot for a portable computing device or the like (referred to herein as a “hand held computer” or “HHC”) a bus and associated conductive contacts for electrically coupling the portable computing device to the thermal printer module, various input and output ports, and a power supply for providing electrical power to at least one of the thermal printer module and the portable computing device coupled to the system.
Turning now to FIGS. 1-8, various embodiments of the modular workboard thermal printer system 100 (referred to herein as the “system 100”) are depicted. In particular, one embodiment of the system 100 shown in FIGS. 1 and 2 broadly includes a housing 102, an HHC holder module 104 functioning as a receiving slot for an HHC 1000, and a thermal printer module 106 mounted with the housing 102 and electrically coupled to the HHC 1000 through a standard electrical communication bus (not shown). The housing 102 is formed with a carrying handle 108, as well as a connector portion 110 formed below the thermal printer module 106. The connector portion 110 functions as the interface for connecting the system 100 to various electronic devices, and includes a number of input and output ports formed on an Input/Output (I/O) panel 136 (e.g., for transmitting data to and/or exporting data from the HHC 1000 or printer module 106) that connect with a bus of the system 100 formed within the housing 102. The connector portion 110 further includes a card reader module 112 for receiving data cards on the system 110 (e.g., swiped cards having a magnetic strip for storing information), as well as a pivotable panel door 114 (see FIG. 7) for concealing and protecting the I/O panel 136 from the external environment. Preferably, the I/O panel 136 is positioned adjacent to the HHC holder module 104 and the thermal printer module 106, and faces the same direction for ease of connecting external devices with the system 100 when the thermal printer module 106 and/or the HHC 1000 are in use. As can be appreciated, the housing 102 may be formed of various lightweight and rigid materials possessing impact resistance, preferably of a non-electrically conductive material, such as plastics or composites.
With additional reference to FIGS. 3, 4 and 7, the HHC holder module 104 is formed with a pivotable sleeve or liner 116 in which the HHC 1000 is slidably received. When the liner 116 and HHC 1000 received therein are pivoted upwardly away from the remainder of the housing 102 (from the stowage position shown in FIG. 3 to the removable position shown in FIG. 4), the HHC 1000 may be slid out of the liner 116 and thereby decoupled from the system 100. Additionally, the up-tilted position, the user can view the display screen of the HHC 1000 and provide input on the keypad of the HHC 1000 with greater ease when the housing 102 is in the horizontal position on a surface.
Turning to FIGS. 5 and 6, the thermal printer module 106 is formed with a thermal printer and a signature capturing pad 118. In certain embodiments, the pad 118 may be a “passive” surface through which the printed paper substrate passes a pressure-sensitive “active” pad. In the case of the pad 118 being a “passive” surface, the pad 118 simply acts as a directional marker for the user to sign with a writing instrument on a paper strip located on the pad. Alternatively, the pad 118 being in the form of a pressure-sensitive “active” pad 118 captures the result of a signature via a stylus with a sensing membrane of the pad 118 and processes the captured signature to store the signature electronically. For instance, the capture signature may be relayed along a communication bus (not shown) formed with the housing 102 to the HHC 1000. As explained in further detail herein, electrical connectors are provided on the housing 102 for both the thermal printer module 106 and the HHC 1000, with the bus formed therebetween, in order to carry data signals between the HHC 1000 and the thermal printer module 106. The signature capturing pad 118 may also be illuminated (e.g., by an LED, electroluminescence, or other light source) to assist the user in viewing the pad 118 area and indicating the location where the user is to sign.
With continued reference to FIGS. 5 and 6, and additional reference to FIGS. 7 and 8, a power supply 120 for the system 100 preferably takes the form of one or more batteries for powering at least the thermal printer module 106 and optionally, the HHC 1000 as well. In one embodiment, the power supply 120 is of the same configuration as a common battery for the HHC 1000 (e.g., a rechargeable lithium-ion battery, a nickel-cadmium battery, a nickel metal hydride battery, etc). The power supply 120 connects to a power circuit (not shown) to deliver power to connectors interfacing with the thermal printer module 106 and the HHC 1000. For instance, the power circuit may be another bus separate from the bus delivering data signals to the thermal printer module 106 and the HHC 1000, but may interface with the same connectors (i.e., different conductive contacts on same connectors). In certain embodiments, the thermal printer module 106 has either a minimal internal power source or no power source, such that the primary or whole power source for operation of the thermal printer module 106 is provided by the power supply 120. In an alternative embodiment, the communication between the HHC 1000 and the thermal printer module 106 may be accomplished wirelessly, instead of through a wired bus. For instance, the communication may be accomplished through transceivers via radio-frequency waves, or by any other short range wireless communication method (e.g., infrared, or other means).
The thermal printer module 106, shown separated from the housing 102 in FIGS. 5 and 6, has an Input/Output (I/O) panel 122, a pivoting top cover 124 for access to paper rolls loaded with the module 106, and an electrical connector 126 having a plurality of conductive channels. The connector 126 of the module 106 interfaces with a mating connector 134 on the housing 102 when the module 106 is coupled with the housing 102, with the system 100 communication bus coupled with the connector 134. The module connector 126 has separate channels for both electrical power (received from the power supply 120) and data communication (e.g., traveling across the communication bus from the connector portion 110 and/or the HHC 1000). Additionally, a connector (not shown) for the HHC 1000 may take the same form as the connector 126, and is formed at the base of the HHC holder module 104 on the housing 102. As seen in FIGS. 7 and 8, a pair of flanged retaining members 128 are formed at an upper region 130 of the housing 102 to serve as a physical retainer for the HHC 1000 positioned within the pivotable liner 116 and in the lowered position shown in FIG. 3. This prevents the HHC 1000 from being unintentionally decoupled from the housing 102, as it is only removable when the liner 116 is in the up-tilted position. A common power connector 132 may be formed in the housing 102 proximal to the power supply 120, so that an external power cord may be connected therewith to supply power to recharge the batteries of the power supply 120 (e.g., from an electrical utility source, another battery, or other power source).
As can be understood, the thermal printer module 106 may be permanently affixed with the housing 102 (as shown in the embodiment of the system 100 depicted in FIGS. 1-4) or may be detachably coupled with the housing 102 (as shown in an alternative embodiment of the system 100 depicted in FIGS. 7 and 8).
In a further embodiment, the HHC holder module 104 is not permanently formed with or attached to the housing 102, but is a separate structure detachable from the housing via any suitable structural attachment or coupling means. Specifically, the detachable holder module 104 ensures that the HHC 1000 may be connected with the housing 102 in the region of the connector panel 110, ensuring electrical coupling with the I/O panel 136, the battery 120, and the bus connecting to the thermal printer module 106. When the system 100 does not have a permanently attached HHC holder module 104, the system 100 forms a fully functioning stand-alone thermal printer system.
The modular workboard thermal printer system 100, in certain embodiments, provides the user with a single type of power source through the power supply 120, so that separate batteries, or battery types, for the thermal printer and HHC are not necessary when both devices are connected to the system 100. Additionally, in certain embodiments, the use of two batteries 120, or one battery 120 of the system 100 and the battery of the HHC 1000, allows the thermal printer to continue functioning when one of the batteries 120 is fully discharged or has been removed.
As can be appreciated, various embodiments of the modular workboard thermal printer system 100 enable portable computing and interfacing of multiple devices capable of printing through a thermal printer module. Furthermore, since certain changes may be made in the above invention without departing from the scope hereof, it is intended that all matter contained in the above description or shown in the accompanying drawing be interpreted as illustrative and not in a limiting sense.
