The present invention relates to point of sale terminals generally.
The following patents are believed to represent the current state of the art:
Japanese Patents JP2000224949 (English Abstract) and JP10056941 (English Abstract) and U.S. Pat. No. 6,403,894.
The present invention seeks to provide an improved point of sale terminal.
There is thus provided in accordance with a preferred embodiment of the present invention a point of sale terminal including a housing defining at least one interior location and at least one opening from the outside through which an insect can enter the at least one interior location, point of sale electronic circuitry located within the housing, at least one light source located within the housing and being operative to illuminate at least one region adjacent the at least one opening and light source driving circuitry operative to cause the at least one light source to output radiation of a type which repels an insect otherwise seeking to enter via the at least one opening.
Preferably, the at least one light source includes an LED. Additionally or alternatively, the at least one light source is mounted onto a printed circuit board forming part of the point of sale electronic circuitry. Additionally, the light source driving circuitry is also mounted onto the printed circuit board.
Preferably, the point of sale terminal also includes at least one reflective surface located within the housing for reflecting light from the at least one light source towards the at least one region adjacent the at least one opening. Additionally, the at least one reflective surface includes an interior surface of the housing.
Preferably, the light source driving circuitry is responsive to ambient light conditions in the vicinity of the point of sale terminal to vary the extent of illumination provided by the at least one light source.
Preferably, the point of sale terminal is selected from a group consisting of: a check reader, a card-based payment terminal, an electronic cash register, a PIN pad, an automatic teller machine (ATM), an automated kiosk and an electronic vending machine.
Preferably, the light source driving circuitry is operative to cause the at least one light source to operate in a pulsed mode of operation and additionally to apply a driving voltage to the at least one light source which is randomly modulated between voltage levels of approximately 30 percent and 100 percent of a rated supply voltage thereto.
There is also provided in accordance with another preferred embodiment of the present invention a method of operating a point of sale terminal including a housing defining at least one interior location and at least one opening from the outside through which an insect can enter the at least one interior location and point of sale electronic circuitry located within the housing, the method including employing at least one light source located within the housing to illuminate at least one region adjacent the at least one opening and causing the at least one light source to output radiation of a type which repels an insect otherwise seeking to enter via the at least one opening.
The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:
Reference is now made to
As seen in
A printer 120 is disposed within printer housing portion 106 and cooperates with a roll of paper 122, which is supported on a paper roll holder 124 located within printer housing portion 106. Printed receipts 126 are output via a printer paper slot 128 defined between an edge 130 of top portion 104 and a corresponding edge 132 of a paper roll cover 134.
In accordance with a preferred embodiment of the invention one or more LEDs 140 are mounted within the housing 100 and arranged to illuminate at least regions adjacent smart-card insertion slot 108 and printer paper slot 128. Preferably, the LEDs 140 also illuminate some or all of the interior of the housing 100, particularly regions which contain electronic circuitry or electrical apparatus which is warm as the result of its operation. Additionally, the magnetic card reader assembly 118 may be suitably illuminated and various regions on the outside of the housing 100 may be illuminated, such as the region of the keypad array location 112. It is a particular feature of the present invention that all physical openings to interior locations in the device are illuminated by one or more LEDs 140.
Preferably the LEDs 140 operate within a wavelength range of 300-1000 nm, and more particularly between 550-700 nm, and in a pulsed mode of operation, preferably within a frequency range of 0.5-30 Hz. Alternatively, randomly timed pulses may also be employed. Additionally or alternatively, the driving voltage to the LEDs 140 may be randomly modulated between voltage levels of approximately 30 percent and 100 percent of the rated LED supply voltage.
In accordance with a preferred embodiment of the present invention one or more interior surfaces within housing 100, such as interior housing surfaces and surfaces of elements located within the housing 100, are formed to be reflective of the light produced by the LEDs 140, thus enabling desired illumination of various regions interior of the housing by a single LED 140. Examples of such reflective surfaces are designated by reference numeral 144.
It is a particular feature of the present invention that LEDs 140 are provided on electrical circuit boards 146 which form part of the functionality of the device and that these LEDs 140 are so positioned with respect to openings to interior locations in the device and to reflective surfaces 144 of the device that insects which begin to enter such openings see the light pulses from the LEDs 140 and are thereby repelled and do not enter through the openings.
Preferably the illumination of the LEDs 140 does not cause the generation of discernable illumination outside of the device during normal operation. Alternatively, pulsed LED illumination can escape from the device. As a further alternative, an ambient light sensor 148 may be included in the device and circuitry on one of the circuit boards 146 may be operative in response to an output of the ambient light sensor, indicating relative darkness, inter alia, to govern the extent of the pulsed LED illumination so as to prevent insects from even approaching the device in the dark.
It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of various features described hereinabove as well as modifications thereof which would occur to persons skilled in the art upon reading the foregoing specification and which are not in the prior art.
