Description

Printing machine with detection of fake credit cards
The present invention relates to small office printers intended more specifically for filling out forms with machine-readable characters. These printers include a base supporting a marble on which is composed a printing plate by means of raised characters, some of which can be interchangeable and placed on the edges of a series of wheels called "character carriers" rotating around a axis housed in the marble, means for positioning the documents to be printed on the marble above the plate, and a printing plate.

 In general, office printers also present on their marble, a space for an embossed character card such as a credit card as well as for an identification plate of the linked character machine which completes the picture. printing with data specific to the type of operation and the machine.

 This kind of machine is used to print a bundle of papers, either chemical, printing appearing when pressed, or with carbon paper interposed between the sheets of the bundle. Printing is carried out by the passage of a carriage (6) which presses the bundle between the rollers (25) and the printing plate comprising the card with embossed characters placed on the marble of the machine.

 The present invention includes a device which makes it possible to verify the authenticity of the credit card (true or false) which is part of the printing plate by noting the inscriptions or the surfaces of red - green or blue colors reacting to UV rays ( long waves) emitted by the detection device.

 During the manufacture of the card, chemical substances are incorporated, either in the form of geometric designs, numbers, signs, or letters, in the plastic interlayer making up the front face of the card.

 These chemicals are invisible to normal light (sunlight or artificial light from an incandescent or fluorescent lamp).

 These chemical substances embedded in the thickness of the credit card have the property of reacting when they are excited by the emission of ultraviolet rays, and appear in red - blue or green colors, depending on the material of the substance added. in the card at the time of its manufacture.

 Another safety can be incorporated into the machine by the presence of a filter placed between the area revealed by the and the observer, this filter corresponding to the ounce length of the re-emission of the fluorescent chemical substance, the color emitted must always be visible to the observer.

If the color is no longer visible, it is because the substance incorporated into the card is not of the same nature as that which has been approved, and there is therefore in this case presumption of frac
In place of or in addition to the filter, there may be mounted a lens, such as a Fresnel lens, through which is looked, inscriptions or a geometric figure, inscriptions or geometric figures which have been deliberately scrambled at the time of their printing on the card, happen to be straightened and readable when reg, burned through this lens.

 The filter and / or the lens can be incorporated in the handle of the machine.

right support the holding plate (8) of this bundle
Figure 1 shows the device incorporated into a machine
to print manually, but we can also imagine the device
in a more complex and automatic machine.

The machine is composed of a marble (1) on which the
printing plate, including the identification plate of the
machine (2), the equipment can include one or two sets of
wheels called "character carriers" mounted on an axis, with a
any positioning system.

The plate (1) has two slides on the front and rear (
between which a roller carriage (6)
backstage.

The carriage slides along the marble, between two stops (16) and
(34) its natural rest position is on the left.

The -epos position, allows easy card placement
comprising the raised characters (7), the guides (24) and
card holders (8) are used for positioning, the card being
partially slid under the UV window (Rep. 13).

 Before printing, the character wheels (3) are adjusted as desired (today's date for example).

The invention comprises a system for holding the pivoting bundle (9)
and operated by the roller carriage (6).

The bundle support (9) consists of a plate with a length
substantially equal to the width of the edge of the bundle (22) to be printed.

This plate is integral with a lever (21), the whole being able to pivot
around an axis (26), a spring (20) fixed on the lever (21) pushes the bundle support (9) to press the plate (4) against the plate (1) of the
machine.

This action clamps the bundle between the bundle support (9) and the plate (1)
The mechanical strength of the bundle (22) being improved by small
teeth (28), appearing on the underside of the plate, holding
bundle (4).

The bundle is installed by returning the carriage to its position
natural rest (fig. 3A) and by sliding the bundle1 into abutment in the
open mouth of the bundle holding (9) the bundle having guided by the projecting part appearing over the entire length of the marble and which is called bundle guide (Fig. 1 - Ref. (35)).

 After this operation, the bundle is ready for printing.

 Detection of the validity of the credit card presented.

To check the authenticity of the card (7), simply roll back
the carriage (6), applying light pressure when leaving its position
rest (see fig. 3 8).

By reversing the carriage (Fig. 3 A) - rep. (6) until it stops (34), its
finger (27) presses the lever (21) which comes out of the notch (33).

During this action the spring (20) presses against the
the sink.

The tilting of the. lever (21) makes contact (11) with the lighting of
the UV lamp (10). The power supply of this lamp being mounted in the base
(23) of the machine.

 The lamp is then on.

 As soon as the carriage (6) is released, the spring (20) pushes the lever (21) on the finger. (27) of the carriage which is automatically returned to its natural rest position, and the finger (27) takes its place in the housing of the lever notch (33).

 The source of UV rays or source of rays (long waves) is located in a lamp holder (12) mounted along the length of the plate (1) in the immediate vicinity of the card (7) to be checked. An opening or window (13) provided on the lamp holder (12) lets through the UV rays, directed on the card placed on the marble and of which approximately the upper 1/3 has been introduced under the window (13).

 Filters or lenses (15) or other devices can be incorporated in the handle (14) of the trolley, to add an additional degree of security in the detection sought.

 These devices designated above add to the verification of the authenticity of the card by examining through the filter the forms (or) (and) of the color emitted by the lumiphorous substances introduced at the time of pressing in the manufacture of the credit card, or the straightening of characters or geometric shapes if you look through the lenses.

 These filters or lenses or masks (15) can be fixed in the handle (see fig. 2) on a support which slides by pivoting and entering a suitable housing created in the handle.

 These filters, lenses or masks can be mounted on the floor (1), on the lamp cover (12) or in the window (13).

 The invention includes the fact that if the credit card does not comply, the transaction therefore the printing is not executed and the blank bundle can be recovered.

 If the card (7) is considered authentic, the operator then pushes the handle from left to right, and the roller carriage (6) is put under pressure and passes over the compressed bundle on the plate of the plate.

 The printing of the bundle is therefore carried out when the movement is interrupted by the (or) stop (s) (16) placed (s) on the (or) slide (s) existing (s) over the entire length marble.

 The stability of the machine during the printing operation can be improved by holding the holding handle (17) with the other hand.

 The stability of the machine is also ensured by the suction cups or feet (18) fixed below the machine base (23).

 When the printing operation has started and the carriage has left its natural rest position, the bundle holder (9) in which the bundle (22) is inserted is closed and. held by the action of the spring (20) on the lever (21) secured to the plate (4) holding the bundle.

 The pressure to maintain the bundle is also increased by the passage of the printing rollers (25) on the plate (4).

 In this system, (see Figure 3 C) have been gathered all the elements intended to make reliable, the holding of the card, the holding of the bundle to obtain the good impression of it, whose printed characters must be read in reading. automatic optics.

 This system facilitates the introduction of the bundle and its positioning to an operator, even an inexperienced one. The bundle holder (9) being wide open, it suffices to slide the bundle along the bundle guide (35) up to the stop provided in the bundle holder.

 As a result, this machine has the advantage over existing printers, of being able to accept bundles of different formats (length width) without having to stop adding or moving on the marble (1). So without any modification.

 When the printing is finished, the carriage is brought back from the right to the left, in this movement the rollers are no longer under pressure and are free, the card is released, and the mouth of the bundle support (9) opens when his finger (27) presses the lever (21) and releases the bundle. From this moment the card and the bundle can therefore be taken back very easily.

 Electronics provided on the machine.

 The power source provided on this machine allows several combinations intended to supply the U.V. (long wave) or black light tube.

 This power supply is incorporated in the base (23) of the machine.

The detection device of this machine can be powered
a) From the mains - 220 v / 50 Hz or 115 v / 60 Hz b) From batteries in a voltage range of 3 to 6 volts
grouping to be carried out with standard batteries.

c) From accumulator (s) in a voltage range of 3 to 6 volts
choice to be made with standard elements (1 or more batteries).

On the other hand, this machine is designed so that the control of the casings
can continue to operate even in the event of a sectE cut
The machine in the event of a power outage, is automatically powered,
on batteries or rechargeable batteries according to the option chosen by the customer, without
have to handle any cut or closing device.

When the machine is provided with mains supply and rechargeable batteries, these
are kept in charge by the sector, and are therefore always
available at the best level in the event of a mains failure.

The feeding device has been calculated in such a way that the fact
to be powered by mains - on battery or accu does not decrease in laughing
the UV illumination power necessary for good development
marks coming from fluorescent substances and without their
perception is attenuated for the operator.

The lamp holder (12) placed above the marble on all its
length and containing the lamp W (10), is .positionk at
closest to the area to be revealed from the credit card which
is slid to 1/3 under the window.

Therefore the maximum light energy is received on the
card, and image and color performance are at a maximum.

The arrangement of the lamp holder (12) shields from
in daylight or artificial light and ensures
thus the contrast necessary for good vision of the colors:
emitted by the substances incorporated in the creative card:
The arrangement of the lamp holder (12) also provides a certain
discretion between the customer and the operator at the time of
credit card verification.
