SK87397A3 - Device for reading cheques - Google Patents

Abstract

Device for reading cheques, particularly the track comprising the account identification number, and comprising two stacked generally parallelepiped-shaped parts (1, 2) made from an insulating material and joined to each other so as to leave an intermediate longitudinal slot having a width that only allows one cheque (8) to be inserted therein. The upper part (1) has a first read head (4) for reading the cheques (8), and a second read head (4') for detecting surrounding electromagnetic interference and for correcting the signal from the first read head (4) so that the indiciae to be read on the cheque are restored without error. The signals from both heads (4, 4') are processed by an electronic card (7) located in a housing (6) in the upper part (1), two magnets (5, 5') being located on either side of the first read head (4).

Description

Bank check reader

Technical field

The invention relates to a device for reading bank checks, in particular a track with a bank identification number.

BACKGROUND OF THE INVENTION

Current devices for reading and / or writing payment means usually perform several functions, such as reading payment cards with a magnetic track, reading and / or writing payment cards with microelectronic circuits, and reading and / or writing bank checks. In order to carry out said operations, the boxes of these devices are provided with electronic or mechanical means for reading bank cards of the mentioned types and in some cases also with optical means for reading bank checks.

The internal arrangement of the boxes of the reading devices is complicated and their relatively high production cost is increased by the addition of means for reading the checks.

In some shops _t and in open spaces check reading errors often occur due to electromagnetic interference affecting the functions of electronic circuits. Sources of electromagnetic interference are various devices in the vicinity of the reading device, such as cash registers or goods inspection system units.

Occasionally, a user may accidentally insert a bank card into the check reading slot and thereby damage the read head of the reader.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The present invention is based on the fact that there is a check-reading device which is simply incorporated into the receptacle and is not affected by electromagnetic interference from the surrounding environment.

The check-reading device is characterized in that it is composed of two substantially prismatic parts formed of a non-conductive material, which are superposed so as to form an elongate slit therebetween, the width of which is dimensioned only for passing the check. The upper part of the device is provided with a first read head for reading checks and an electromagnetic disturbance detector from the surrounding environment, which adjusts the read head signal to restore error-free check features. The sensor head signals and electromagnetic interference detectors are processed by an electronic tag, which is stored in a recess in the upper part. The scanning head is lined on both sides with magnets that magnetize the check marks.

The device is also characterized in that its lower part is provided with a spring tongue which is placed against the first pickup head in the slot for receiving the checks.

The electromagnetic disturbance detector incorporated in the upper part of the device according to the invention is a second sensing head which is aligned with the first sensing head on the same transverse axis of the upper portion.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1 shows a sectional view of a device according to the invention, FIG. 2 shows a front view of a part of the spring tongue on the lower part of the device

An embodiment of the invention

The device shown in FIG. 1 is formed from two prismatic parts X and 2. made of plastic or other non-conductive material. Both parts are connected, for example, by heat welding the lower surface 10 of the upper part 1 with the upper surface 20 of the lower part 2. The lower part 2 is provided with a recess 21 which forms a slot 3 for receiving a bank check.

The slot width is approximately 1/6 mm to prevent the bank card from being inserted.

The first sensor head 4 is completely or partially embedded in the body of the upper part X of the device, against the slot Z for inserting the bank check 8 and in particular against the marks on the identification track 4. Magnets 5 and 5 are mounted on both sides of the sensor head. , which, due to the read operation, magnetize the characters on the identification track. The second sensor head '' is located in the plane of the sensor head 4, in the same transverse axis XX 'of the device, and protrudes from the upper part 1 to receive a signal from the vicinity of the check reading device. The electronic tag 7 is inserted into the recess 6 and is connected to the sensor heads 4 a 'by the electronic conductors 40 and 40'.

The electronic tag Z is provided with power components, in particular an amplifier 71 which amplifies the signal captured by one of the sensing heads 4 and 4 ', the filter circuit 72 and the conversion circuit (not shown) of the analog signals of both sensing heads 4 and 4' to digital signals that can be processed. error correction program. The microprocessor 73 compares the digital signal transferred from the sensor head 4 to the digital signal converted from the sensor head 4 ', which varies depending on the surrounding electromagnetic interference.

By comparing the sensor head signal 4 'in the absence of interference and the signal affected by the interference, a correction value is obtained by which the microprocessor 73 adjusts the signal from the sensor head 4 by adding or removing this value to the signal to restore accurate. characters on the check identification track.

The digital code of the check characters passes through the electronic conductor 74 to the central data acquisition and processing unit. This unit may be a microcontroller which sends a CMC7 track signal to the service system via the appropriate interface and indicates that a check payout means is used.

Fig. 2 shows the front part of the upper surface 11 of the lower part 2, which is provided with a spring tongue 9. The spring tongue is positioned longitudinally against the scanning head 4 and its task is to press the check, in particular its CMC7 portion against the scanning head they were more legible on the track.

It is advantageous to place the device according to the invention in a box having an adapted internal structure and to connect it to a microcontroller which processes signals from other means of reading means of payment. Thus, the microcontroller can receive the signals processed by the electronic tag and send them to the banking transaction service system.
