• the CPU bus can be connected to the LCD panel 90 by way of an appropriate bus extension 106 and backlighting signals are conveyed via a data highway 108 to the backlight element 110 associated with the LCD panel 90.
• an integral panel such as that produced by Hitachi Type No. LMG7401PLBC may be employed which includes an integral backlight unit and interface allowing direct connections to be made between the processor and the panel. Contrast may be achieved by way of a variable resistor 110 in accordance with the manufacturer's technical data sheet.
• a DC power supply 112 provides appropriate power along 114 to the LCD panel assembly and via 116 tc the CPU.
• external RAM is provided by way of a memory chip 118 which is connected to the CPU bus via data highway 120.
• an external ROM 122 is connected via a data highway 124 to the CPU and a non-volatile memory chip 126 is connected to the CPU via data highway 128.
• a CAT port for entering and retrieving data such as illustrated at 96 in Figure 13B is connected via a data highway, typically a simple serial link such as 130.
• a touch memory device such as produced by Dallas Semiconductors is noted by reference numeral 76 as illustrated also in Figure 12B.
• a preferred encapsulated memory chip from Dallas is Type DS 1995-F5 and an appropriate reader comprises device DS 9092.
• the touch screen device 86 is an analogue device and eight bit parallel latch (not shown) is employed to transfer parallel data from the CPU.
• Data for updating the CPU about the machine to which the control panel is connected can be derived from the host copier via data highway 132 and a copier panel input/output interface which typically includes a multiple way two-part connector.
• the interface is generally designated 134.
• serial information is derived from the host copier such as clock signals, latches and the like, and these are supplied to the CPU by the interface 134 and data highway 136.
• the serial information from the host copier will include information indicating which of the LED's would have been illuminated in the original panel indicating that the function which has been selected and/or is now operational and the CPU is programmed (in a manner to be described) so as to interpret such information passing thereto along 132 and 136 so as to update the display in the LCD panel 90 as appropriate.
• the CPU in turn delivers data in the opposite direction along the highway 136 and 132 to the host copier in the form of simulated operating commands to cause the ccpier to perform the desired function or functions initiated by pressing the appropriate region of the touch screen 86.
• Operation of the CPU is dictated initially by the contents of the ROM 122.
• the contents of the ROM is transferred to the CPU RAM which may include part of the RAM 118 and the CPU is caused to perform the usual initiating checks on the processor itself, the resident RAM and the external RAM 118, and the various ports to the CPU.
• a ready signal causes the CPU to read the data contained in the non-volatile store 126 and load the data therefrom into the RAM 118 and/or installed memory within the processor causing the processor to display a default screen in the LCD panel 90 and to programme the touch screen 86 accordingly.
• the default screen merely contains the words
• the touch screen 86 is not programmed so as to be responsive to any touch and the machine will sit in this quiescent condition until the receptor 72 is touched by an appropriate CAT 76.
• ID data can be permanently stored therein and the CPU is programmed by the instructions form the non-volatile store 126 to read the ID data first and compare it with a look-up table to determine if the CAT is valid. If it is, the data from the CAT is then transferred to the RAM 118 and the NV instruction set from 126 then causes the CPU to write the appropriate display in the LCD panel 90 and instruct the appropriate programming to the touch screen 86 so as to correspond therewith. The machine is now ready to be operated by the user touching the appropriate identified region of the touch screen as indicated in Figure 12 so that the CPU can transfer appropriate instructions contained in the NV store instruction set via the data highway 136 and 132 to the host copier to perform the function.
• the CAT port and CPU act as a double touch response circuit so that if the same CAT 76 is touched to the receptor 72 (96) the CPU removes the data stored in the RAM 118 and reinstates the NV storage default instruction set to write the default message to the LCD panel and deprogramme the touch screen 86.
• the default screen produced by the resident non-volatile instructions set produces a simple display of perhaps cr.e or two buttons in the panel 90 and appropriate programming of the touch screen 86 and associated switch matrix so that the default mode of the machine is one in which one or two simple copying functions can be performed without the need to enter data from a CAT such as 76.
• the resident instruction set recognises if a touch memory device 76 contacts the receptor 72 and if it is recognised as a valid CAT for use with the machine, data from the memory device 76 is transferred via the CPU to the RAM to replace the data previously stored in the RAM or enlarge the date stored therein so as to produce a more complex display in the pane 90 and appropriately more complex switching matrix associated with the touch screen panel 86.
• entering data from a carrier 76 enables the default basic functionality machine to be upgraded, for example to permit enlargement or reduction as well as size for size copying.
• the CAT port 96 double-acting touching the same memory device 76 against the receptor 72 causes the RAM 118 to be cleared and the basic default information from the non-volatile store 126 to be entered in the RAM 118 once again and the default screen and switching matrix to be set up once again.
• Additional ports on the Intel CPU allow data input and data output to be supplied to or derived from the processor such as a coin freed mechanism so that the CPU is inhibited until an appropriate coin or token has been inserted in a slot (not shown).
• a card reader (not shown) is provided into which a card having credit information stored thereon can be inserted and which can be read and transferred via the input port to the CPU and the RAM, and after decoding, the CPU can be rendered operational thereby enabling the touch screen 86 to be responsive and allow the user to perform operations using the machine within the limits of the credit read from the card. If at the end of the exercise a credit remains within the RAM 118, the CPU transfers the credit and decodes it for appropriate writing back to the card via the output port.
• microcon Trade Mark
• encapsulated memory chips as supplied by Dallas Semiconductor can be attached for example to a keyring for convenient use by the user and the devices can be manufactured as a coded activator tag (CAT) so that the user can configure the keyboard of the copier to his or her own specific requirements using for example as set of instructions to programme the CAT himself, or using a CAT programming aid separate from the machine.
• CAT coded activator tag
• ceded activator tags such as described may be programmed by way of data supplied from the CPU via the CAT port 96 during a so-called learn mode, and to this end the non ⁇ volatile storage includes an instruction set for enabling the processor to recognise a sequence of functions and transfer these into the RAM and from the RAM to the CAT port and the memory device 76 when touched thereon at the end of the so- called learn mode.
• the learn mode the user simply selects from the display screen the function required to be associated with the CAT and having indicated the desired function, presses a transfer button in the display (which to this end is preferably a special learn mode display panel) to cause the function creating data to be transferred to the memory device 76.
• the appropriate display screen is either called up or created by the user from a menu and after pressing the transfer button the data associated with that display panel is transferred to the memory device 76 so that when the machine is out of its learn mode, touching the receptor 72 with the programmed device will transfer the stored data back into the machine and cause the appropriate display panel and switching matrix to be established in accordance with the pre-programmed information in the touch memory device.
• a number of similar touch memory devices may be programmed in a similar way so that a group of users can all acquire the same configuration on the machine.
• the Dallas Semiconductor devices include unique ID information stored in the device during manufacture and which it is impossible to alter or change without destroying the device. By arranging that this information can be read by the CPU and entered into a suitable look-up table in the non-volatile store 126, so the machine can be instructed to recognise the memory device concerned. If a memory device which has not been "shown" to the machine in its appropriate mode is presented to the machine, the machine will not recognise the ID and data will not be transferred from the memory device.
• the node ir. which memory devices ca.n be entered as valid devices for tne machine is a mode which can only be entered by an appropriate person with appropriate authority and information using for example PIN numbers and/or other keys to ensure that unauthorised users cannot enter the ID of their CAT into the machine.
• Key operators may be issued with a coded activator tag which enables them to select a more complex keyooard merely by pressing their CAT on the data receptor 72. After a copying activity has been completed the user returns the keyboard to its default or dormant setting by simply touching the CAT against the receptor 72 once again.
• the ID can be stored in any number of copiers or other machines
• the one CAT can be rendered acceptable to two cr more copiers or other machines or in the reverse
• a machine may be encrypted so as to be unresponsive to certain CAT ID'S, or rendered capable of only operating when CAT ID'S are presented to it which are already stored within its non-volatile store so that specific CAT'S may be used on specific machines and not on others.
• Public Access - A copier in a library is fitted with a coin/card system and configured for self-help use.
• the default keyboard is, for example, set to take single copies with just three buttons (A4, A3 and Reduction to A4) thus making it very easy for members of the public to operate.
• a key operator can, at any time, apply a CAT to the CAT reader, which automatically overrides the coin/card system and reveals a more complex keyboard allowing, perhaps, multiple copies, a number of reductions and enragements, zoom etc.
• the operator touches the CAT reader again with his CAT, the coin/card system becomes operational and the default public access keyboard (A4, A3 and Reduction to A4) is again revealed.
• Office copying A copier is placed in an office and each member of staff issued with a programmed CAT allowing them to create a keyboard which is relevant to their particular job function. Some individuals might only need to copy A4 size for size, others might need to carry out more complex tasks. A partially sighted person could call up a keyboard with larger buttons which are easier to see. Normally complex keyboards can be made easier because functions that might ordinarily require 3 or 4 buttons to be pressed in sequence could be actioned by pressing only a single button.
• a preferred copier to which the system is applied is compact with front loading cassettes (up to 5 containing a total of 2500 sheets). Substantial reductions can be made in ozone emissions and noise levels, major plastics parts marked for recycling and toner recycled internally, obviating the need for waste toner containers.
• control panel may be ade of steel so as to be extremely hardwearing. It is also mounted at an angle to the platen so that the controls are more easily accessible to wheelchair users.
• An optional security cabinet may be available which affords protection to the machine body and secures all the paper trays and other opening panels.
• Another option is a conversion which creates a localised right- angle between the glass platen and the sloping control panel (allowing improved copying into the gutter of tightly bound books) and adds a trailing-edge delete feature which whites-out the end of the copy and switches off the scanning lamp when it has cleared the end of the book.
• the control panel is now in a condition to generate and display the start-up screen in the LCD and upon completion of the data transfer to the RAM from 126, the default screen is drawn in the LCD panel 90 and suitable backlighting commands are derived from the RAM data associated with the default screen.
• the default screen in this example contains at least one button representation for making eg same size copies onto A4 portrait paper in the case of a copier machine.
• Logic 136 determines when the display and switch panel 86 is touched and the analogue signals from the touch screen matrix are digitised and decoded by the CPU, causing the CPU to release a command via 134 to the host copier to effect a same size copy of what is on the copying platen, onto A4 paper drawn from the "portrait" tray.
• Secondary logic 138 responds to contact v/ith the CAT PORT 94 by a CAT 96.
• a detected touch requests the CPU to read the CAT ID and other resident data to compare with data stored in the NON-VOLATILE (NV) memory 126. If the comparison is favourable, the logic circuit 140 triggers the CPU to download data from the CAT to the RAM 118 to replace the default screen data stored therein from NV Store 126.
• NV NON-VOLATILE
• the new data is used to redraw the LCD display screen to define the buttons for the functions provided by the CAT concerned.
• the CPU additionally reprogrammes the touch screen 86 or a look-up memory with the CPU, so as to redefine the switching functions of the different area of the touch screen to correspond with the new function buttons in the LCD display screen.
• Subsequent touching of a region of the touch screen 86 results in an appropriate instruction being generated by the CPU using data stored in the RAM, to convey to the host copier 133 the signals to trigger the relevant functional component(s) within the host copier to perform the requested function.
• Tertiary logic 142 responds to a second touch by the same CAT on the port 94, by comparing the CAT ID with the last CAT ID and if satisfied the logic clears the RAM and reinstates the default screen data in the RAM for the NV Store 126, causing the Display 90 to present the default screen (or a look-up memory within the CPU) so as to revert the touch screen to the default mode condition once again.
