Abstract

A cash dispenser (1) is described which comprises a housing (1A), a cash dispensing opening (5) arranged in the housing (1A), and a closure (5A) that closes the cash dispensing opening (5) in a first position and unblocks the same (5) in a second position in order for cash to be dispensed. According to the invention, at least one contactless sensor (S1, E1; S2, E2, RS) is provided for recognizing manipulation devices that are placed in front of the cash dispensing opening (5).

Description

Title: ATM

The invention relates to a cash dispenser with a housing, a housing arranged in the money dispensing opening and a closure which closes the cash dispensing opening in a first position and the money dispensing opening for the cash dispensing releases in a second position.

US Pat. No. 7,344,065 B1 describes measures by which manipulation of the closure can be detected by monitoring the position of the closure or the movement of the closure during opening and closing.

This, however, only manipulation of the closure itself can be detected. With the measures according to US Pat. No. 7,344,065B1, however, no manipulation devices are detected which are attached, for example, in the form of a specially prepared closure dummy in front of the cash dispensing opening and before the actual closure in order to fraudulently access bank notes (so-called cash trapping). ,

The object of the invention is therefore to provide an ATM, can be prevented in the fraud attempts with pre-built before the money dispensing manipulation facilities.

This object is solved by the features of patent claim 1. The subsequent dependent claims contain advantageous embodiments.

According to the invention, at least one non-contact sensor for detecting manipulation devices mounted in front of the cash dispensing opening is provided. provided for. In this way, pre-built manipulation devices can be reliably recognized, whereby whenever a pre-built manipulation device has been detected, the payment of money is prevented, an alarm is generated and / or the automatic cash dispenser is taken out of operation. In this case, a cash dispensing transaction currently being processed would also be aborted if a pre-built manipulation device were detected, so that a banknote bundle provided for the payout would no longer be offered for removal in the cash dispensing opening.

In this case, in an advantageous embodiment, at least one light barrier is used for monitoring the near zone of up to approximately 10 mm in front of the cash dispensing opening and a reflection light sensor for monitoring the medium long range of up to approximately 150 mm in front of the cash dispensing opening.

FIG. 1 shows a schematic view of a cash dispenser. In the cash dispenser housing (1A) there is a monitor (2) for displaying information for the user, a card slot (3) for entering a bank card, a slip dispensing slot (4) as well as the cash dispensing opening (5) according to the invention. In this case, cash dispensing opening (5) is provided with a preferably motor-driven shutter (5A) which closes the cash dispensing opening (5) in a first position (see FIG. 4) and releases the cash dispensing opening (5) for dispensing the cash in a second position (see FIG 4A). This closure (5A) is often referred to as a shutter. Money to be paid out (banknotes) is presented to the customer with the shutter (5A) open through the then released cash dispensing opening (5) for removal. To seal the cash dispensing opening (5) against water, dust, etc., this is surrounded by a same enclosing frame (6), opposite to the cash dispensing opening (5) and the shutter (5A) after - A -

Protrudes outside. The frame (6) as well as the cash dispensing opening (5A) has a substantially rectangular cross-section. The fraudulent attacks on the cash dispensers, which are to ward off according to the invention, carried out by such manipulations, in which before the cash dispensing opening (5), preferably in or on the frame (6), a specially prepared shutter dummy, is mounted.

In a first embodiment, a light barrier for detecting manipulation devices mounted in front of the cash dispensing opening (5) is provided as a non-contact sensor. The light path (LW1) of this light barrier is shown in FIGS. 2 to 4A. The light barrier is formed by the light transmitter (S1) and the light receiver (E1). When the shutter (5A) is open, the light path (LW1) runs at least partially in the region in front of the money dispensing opening (5), so that a manipulation device (not shown) placed in front of the dispensing opening (5) leads to an interruption of the light path and is thus recognized , In this case, the light path (LW1) extends obliquely through the cash dispensing opening (5). Therefore, in the shutter position in which the shutter (5A) closes the cash dispensing opening (5), the light path L (LWI) is also interrupted by the shutter (5A), i.e., the shutter 5 (Fig. the light path (LW1) passes through the area indicative of the cash dispensing opening (5) corresponding to the area of the shutter (5A) closed. The light path (LW1) extends at an angle of approximately 5 degrees with respect to the longitudinal extent of the cash dispensing opening (5). With the area of the light path (LW1) extending in front of the cash dispensing opening (5), at least a majority of the left half can be monitored in front of the cash dispensing opening (5).

In order to realize the light path (LW1) extending obliquely through the cash dispensing opening (5), the light receiver (E1) is located in the cash dispenser housing (1A) behind the cash dispensing opening (5), while the light emitter (S1) is located outside the housing (1A) in front of the dispenser Cash dispensing opening (5) is arranged. The light emitter (S1) is slightly to the left of the cash dispensing The light receiver (E1) is located slightly to the right of the cash dispensing opening (5) and is largely obscured even when the shutter (5A) of the ATM case (1A), so that stray light (sunlight, artificial light) the light receiver (E1 ) is reached only when it enters the cash dispensing opening (5) at a similar angle as the light emitted by the light emitter (S1). By this arrangement of light receiver (E1) and light emitter (S1) of Störlichteinfluß on the light barrier is already significantly reduced. Immunity to light immissions is important, as cash dispensers are always exposed to sunlight and / or artificial light, whereby in particular outdoor ATMs that are outdoors may be exposed to considerable solar radiation depending on the location. The light transmitter (S1) arranged outside the ATM box (1A) is preferably arranged in the frame (6) surrounding the cash dispensing opening (5) (see FIG. 3). This has the advantage that an additional receiving / fastening element provided specifically for the light transmitter (S1) is not required.

In both cases, i. even when the light emitter (S1) and not the light receiver (E1) is disposed behind the money dispensing opening (not shown), the light path (LW1 ) ensures that close monitoring takes place immediately after the cash dispensing opening (5).

In order to reduce the sensitivity of the light barrier against stray light further measures are provided in addition to the concealed installation of the light receiver (E1): a) Operation of the light barrier with infrared light (IR light): This is already a major part of the disturbing sun or Artificial light hidden. For this measure, the frame (6), in which the IR light transmitter (S1) is integrated, consists of an IR light at least partially trans- Parent plastic. An optical filter (not shown) is preferably arranged in front of the light receiver (E1) so that only IR light reaches the light receiver (E1).

b) Operation of the light barrier with pulsed light (see FIG. 6):

Thus, the (alternating) signal, which is caused in the light receiver (E1) by the transmitter light, can be separated in a simple manner by a decoupling capacitor caused by disturbance light noise, since the temporal variations of the disturbing light compared to the useful signal are low.

c) Use of a phototransistor as light receiver in conjunction with an adjustable load resistor or an adjustable current source (see FIG. 6): To prevent the light receiver (E1) from being overdriven in the case of particularly strong stray light and then to the useful light of the light barrier transmitter (S1) can no longer react, is used as a light receiver (E1), a phototransistor, which is connected to an adjustable load resistor or with an adjustable power source. The adjustable load resistor / current source is connected in parallel with the actual load resistor. An increase in stray light also leads to an increase in the voltage that drops at point A on the load resistor. This voltage is in turn supplied to a Störlichtschutzschaltung, where this voltage is compared with a reference value. In this case, the Störlichtschutzschaltung causes depending on the voltage at point A, a control of the adjustable current source such that a large part of the current generated by stray light in the phototransistor is conducted past the working resistor and not critical leads to a voltage increase at point A, which otherwise the phototransistor insensitive would make the useful light. In a second embodiment, a further second light barrier is provided as a non-contact sensor whose light path (LW2) also extends at least partially in the area in front of the cash dispensing opening (5) when the shutter (5A) is open, so that a manipulation device attached in front of the cash dispensing opening leads to an interruption of the light path (LW2), wherein the regions of the light paths (LW1, LW2) of the two light barriers, which run in front of the cash dispensing opening (5), are at least partially different. While the first photoelectric barrier (S1, E1) monitors at least a majority of the left half of the money dispensing opening, at least a majority of the right half of the money dispensing opening (5) can be monitored with the second photoelectric barrier (S2, E2), so that the money dispensing opening (5) is monitored over its entire length. In this case, the light paths (LW1, LW2) of the two light barriers intersect at least in the projection onto a projection surface (see FIG. 3). The point of intersection of the two light paths (LW1, LW2) with respect to a projection surface, which extends substantially perpendicular to the surface of the shutter (5A), preferably lies directly behind the shutter (5A). This crossover arrangement with intersection point behind the shutter (5A) has the advantage that shading of both light barriers by the fingers of an operator who intervenes in the money dispensing opening is very unlikely. It should in fact be ruled out that an operator who engages after opening the shutter (5A) but before the money spent in the area of money dispensing opening (5) accidentally triggers an alarm, prevents the dispensing of money or the cash dispensers out of service. According to the invention, a protective action (alarm, etc.) only takes place if, after opening the shutter (5A), the light paths (LW1, LW2) of both light barriers are interrupted.

With regard to the second light barrier (S2, E2), the arrangement of light transmitter (S2) and light receiver (E2) as well as with regard to the measure men against the Störlichteinfluß the above executed to the first light barrier.

In a third embodiment (not shown), at least one third light barrier is provided as contactlessly operating sensor, wherein in this embodiment both the light emitter and the light receiver of this light barrier are arranged in the window frame. The light path of this light barrier lies completely in front of the shutter (5A) and does not run obliquely through the cash dispensing opening (5), i. the light path does not pass through the fictitious shutter surface. However, this arrangement has in comparison to the arrangement of the two above-described light barriers (S1, E1, S2, E2) the disadvantage that monitoring immediately behind the cash dispensing opening is not possible because the built-in frame (6) components (light emitter, light receiver) structurally already have a certain distance to the cash dispensing opening (5) / shutter (5A). This third embodiment can also be combined with the two embodiments described above.

In a fourth embodiment (see FIGS. 2, 4A), at least one reflection light sensor (RS) operating with infrared light is arranged in the frame (6) as a non-contact sensor, which has a manipulation device mounted in front of the cash dispensing opening (5) on the basis of the light signal reflected by the latter recognizes. The detection range of the reflection light sensor (RS) extends beyond the frame (6), so that a center distance range of up to about 150mm in front of the cash dispensing opening

(5) is detected for the detection of manipulation devices. This would make it possible, for example, to recognize a shutter dummy mounted on the frame (6).

In order to prevent false alarms, etc., for example, when an operator stands very close to the frame (6), a protective action (alarm, etc.) in response to - S -

an object detected by the reflection light sensor (RS) is initiated only when the reflection light sensor permanently detects an object within a predetermined time. For this purpose, when objects are detected in the detection range of the reflection sensor (RS), a timer is started. Only after expiration of a preferably configurable monitoring time then an alarm etc. is triggered. If the object is removed within the monitoring time, the timer is reset.

The reflection light sensor (RS) consists of at least one light transmitter (RSS) and at least one reflection light receiver (RSE), preferably an array of multiple receivers, both of which are arranged in the transparent to IR light frame (6).

The combination of the two crossed light barriers (S1, E1, S2, E2) with the reflection light sensor (RS) ensures monitoring of the money dispensing opening (5) both in the near and in the medium distance range, the two areas preferably being in the transition area overlap to increase safety.

FIG. 4A shows a section through the cash dispensing opening (5) when the shutter (5A) is open. In this case, the course of the light barrier light path (LW1, LW2) is shown in section and dash-dotted the main monitoring direction of the reflection light sensor (RS). As can be seen, the light barriers with their light path (LW1, LW2) are aligned obliquely downward, while the reflection sensor (RS) is aligned with its monitoring range obliquely upward. This is as complete as possible monitoring of the area before the cash dispensing opening (5) achieved. In this case, the terms "diagonally downwards" and "diagonally upwards" refer only to the illustration in FIG. 4. In reality, the terms "bottom" and "top" are used in the context of the actual installation situation. at the money dispensing opening (5) and the shutter (5A) ₁ which may differ from that shown.
