Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to magnetically encoded card acceptors. In particular, the present invention relates to magnetically encoded card acceptors used in prepaid toll systems.

[Prior art]

Cards used in vending machines or prepaid fare machines include Maxwell et al., U.S. Pat.
(referred to as "prior art") has been disclosed in the past. In the conventional technology, for cards having a unique code with a plurality of protrusions formed along the longitudinal direction of the flat card, only cards with this code recognized as good by a vending machine sensor are accepted. A portion of the card is removed in proportion to the price of the product or service.

In the conventional technology, each card has a unique symbol, and only those cards with this symbol that are recognized as being in good condition open the gate, are accepted into the device, and pass between a pair of gears, reducing the consumption amount (service amount). A portion of the card will be cut off for the amount of the fee.

[Problem to be solved by the invention]

However, in the prior art, while the card acceptor is executing a desired process,
Even if the card is stolen or fraudulently used, it cannot be dealt with. Furthermore, since the information code written on the card is limited to a single code that matches the system, it is not possible to accept cards with multiple pieces of information written on them.

In view of the above, the present invention does not accept defective cards and does not allow unauthorized use (the meaning of unauthorized use will be explained later, but it is possible to stop using a magnetically encoded card midway through use, so-called cancellation). The present invention aims to provide a multifunctional card acceptor system that can use cards having multiple types of information.

[Means to solve the problem]

In order to solve the above problems, a magnetically encoded card acceptor according to the present invention includes: (a) one code is recorded in the longitudinal direction, and a plurality of different codes are recorded in parallel at intervals in the longitudinal direction; (b) having a card presence detector electrically connected to the system control means for providing an output indicating that the card has entered the system; (c) advancing the card; and a card drive means having a reversing circuit, and at least one decoder electrically coupled to the magnetic card code reading mechanism and the system control means, respectively, the decoder detecting when the system control means provides an output. and the decoder is manually resettable to a plurality of different code reading patterns in response to a magnetic code received; including good and bad code control circuits respectively electrically coupled to the means, the forward drive cancel and reverse initiate means being electrically connected to said system control means; a card movement limit stop and card shear actuation mechanism electrically connected to the initiation means, the magnetic card code reading mechanism and the card drive means, and the card shearing machine, respectively; means for simultaneously interrupting operation of the drive means and the magnetic card code reading mechanism, the card shear actuation mechanism cutting a predetermined length of the card with the fixed cutting member when the card reaches the card travel limit stop and shear actuation mechanism; (f) a magnetically encoded card drive reversal mechanism electrically coupled to said good and bad code control circuit and forward drive cancellation and reverse initiation means; (g) the magnetically encoded card drive reversal mechanism is operably coupled to the card shear actuation mechanism and performs a predetermined service that operates concurrently with the cutting of a predetermined length of the magnetically encoded card by the card shear actuation mechanism; (h) the drive reversing mechanism has a reversible motor, the reversible motor having a reversing torque switch on its output shaft; If you try to pull out the inserted card before it is serviced by a device that performs the specified service that operates at the same time as the predetermined length of the coded card is cut, the reverse torque switch will operate and the card will be ejected in the withdrawal direction. (i) a second magnetic code reading head positioned in close proximity to the card within the system for sensing a plurality of different encoded information on the card;

[Effect]

Upon inserting into the acceptor a flexible magnetically encoded card carrying a number of instruction codes equal to the number of purchases the cardholder is entitled to use;
A card presence detector electrically connected to the system control means provides an output indicating the intrusion of a card into the system. The card is then further pushed past a card presence detector and into a card drive means having forward and reverse circuits. A magnetic code reading mechanism including a second magnetic code reading head for reading a plurality of different codes recorded at intervals on the card is arranged such that its position can be adjusted in proximity to the passageway of the card. has been done. The decoder is electrically coupled to the magnetic code reading mechanism and the system control means, respectively. The decoder is manually resettable to a plurality of different code formats and is responsive to the detected magnetic code when the system control means provides the above output. The decoder provides two outputs, one that the detected code is good and one that the detected code is bad (rejected). A good or bad code control circuit is electrically coupled to the decoder, forward drive cancellation and reverse drive initiation means, respectively. The forward drive cancellation and reverse drive initiation means are electrically coupled to the system control means. The good or bad code control circuit allows the passage of a control signal upon detection of a good code, thereby causing the card drive means to supply the card to the acceptor system, or when a card with a bad code attempts to enter the system. The card is ejected. This is accomplished by interrupting the power to the ejection card drive means, disconnecting the device to be controlled, and outputting a reversal signal to the card drive means.

After passing the magnetic code reading mechanism, the good card is sent to the card travel limit stop and card shear actuation mechanism. The card travel limit stop and card shear activation mechanisms are electrically connected to the forward drive cancel, reverse start means, magnetic card code reading mechanism, and card drive means and card shear activation mechanism, respectively.

The card travel limit stop and card shear actuation mechanism simultaneously interrupts operation of the card drive means and the magnetic code reading mechanism such that the movable cutting member is pulled down to cut a predetermined length of the magnetically encoded card in conjunction with the stationary cutting member. Ru.

A magnetically encoded card drive reversal mechanism is electrically coupled to the good and bad code control circuitry, forward drive cancellation and reverse drive initiation means. Following operation of the card shear actuation mechanism, the magnetically encoded card drive reversal mechanism ejects the prepaid magnetically encoded card that has been sheared to a predetermined length.

In the present invention, when the magnetically encoded card is cut to a predetermined length and ejected (with the fee paid in advance), the device is activated so that the card can receive a predetermined service. If it is ejected before it is cut to length, the device will not operate and will not be able to receive any service. In other words, a predetermined service cannot be enjoyed simply by inserting the card. Therefore, if an attempt is made to use the card fraudulently (or cancel it) in order to enjoy only the prescribed services and remove the card without consuming it (without paying the price),
The drive reversing mechanism of the present invention includes a reverse torque switch, and if the card is intentionally removed as described above during operation of the system,
A reverse torque switch is actuated to sense this action and reverse the drive means to eject the card. In this way, if the card is ejected before a certain amount is cut off (before prepayment of fees), the device will not operate and no service will be available, so unauthorized use is completely prevented.

In the present invention, the card acceptor only accepts cards with a certain code.
The field of the magnetic code reading mechanism can be adjusted manually.

As detailed above, a card is inserted into the acceptor of the present invention, and only when the code recorded on the card is good will the card be accepted into the system and a portion of the card will be sheared and ejected.
If there is any unauthorized use (or cancellation) during the predetermined operation of the acceptor, the card is immediately ejected, and since cards with multiple codes can be used, it can be used for multiple purposes.

At the top of FIG. 1, shown in dotted lines to the rear of the magnetically encoded card acceptor 12 is a flexible magnetically encoded card 11 with a magnetic cord 10 attached thereto. The characteristics of the code will be explained in detail below.

The magnetically encoded card 11 is inserted into the slot 13 shown in FIG. Slot 13 is the second

In this case, the idler wheel 24 is a rubber card drive wheel 23.
A spring (not shown) force acts to press it. Magnetic encoded card 11 is inserted into slot 13
, and when the rubber card drive wheel is actuated in the manner described below, the magnetically encoded card 11 is inserted into the idler wheel 24 and the rubber card drive wheel 2.
3, the magnetically encoded card 11 is drawn into the card acceptor 12 for further processing and, once processing is completed, returned to the user of the system. The reversible motor 36 inserts and ejects cards into and out of the card acceptor 12 via drive mechanisms such as a shaft 38, a worm gear 37, a gear 18, a shaft 19, and a rubber card drive wheel 23.

Relay support casing 43 retains motor support flange 39 by means of fasteners (not shown). A vertical support plate 40 is integrally fixed to a support casing 43 of the relay, and a fixed cutting member 63 (the function of which will be described later) is held so as to be flush with the upper end surface of the vertical support plate 40.

Card support plate 14 is fixed to vertical support plate 40.

Card support plate 14 also supports a code detector cover plate 34 which supports a magnetic code reading head 52 having a pair of leads 53,54.

In FIG. 1, a part of the code detector cover plate 34 is cut out to clearly show the presence of the idler wheel 51. It is pressed against the reading head 52 by a spring (not shown).

56 is a second magnetic code reading head arranged in parallel with the magnetic code reading head 52, and 57 and 58 are lead wires.

A relay 44 having lead wires 29, 30 is fixed within the support casing 43 of the aforementioned relay. The relay 44 has a spring (not shown) inside.
sleeve 48 and armature detent 47 having
An armature 46 extends upwardly through a forked hole therein. The upper end of the armature 46
It has a pivot bolt 49 that passes through the armature and fixes the armature to one end of the clamping arm 61. The other end of the pincer arm 61 is pivotally connected to the vertical support plate 40 and the fixed cutting member 63 by a pivot bolt and washer arrangement 64. One end 66 of a spring 65 wrapped around the pivot bolt 64 is fixed in a hole (not marked) in the pincer arm 61, and the other end 67 is fixed in a hole (not marked) in a fixed cutting member 63.

The action of spring 65 and a spring (not shown) in sleeve 48 holds pincer arm 61 upwardly until relay 44 acts to pull pincer arm 61 down. The clamping arm 61 includes a movable cutting member which, together with a fixed cutting member 63, accurately cuts a portion of the magnetically encoded card 11 (indicated by a dotted line between the fixed cutting member 63 and the movable cutting member 62 in FIG. 1). A member 62 is fixed.

On the horizontal support plate 45 fixed to the upper part of the support casing 43 of the relay, two units are fixed, one of which is a card travel limit stop mechanism 71 and the other one is a card drive reversal mechanism. This is a starting mechanism 81 .

The card movement limit stop mechanism 71 consists of a fixed contact support member 76 and a base plate 72. The fixed contact support member 76 has lead wires 78, 79, and the base plate 72 has an adjustment slot 73 bored therein. 7
A movable contact 4 is pivotally connected to a fixed contact support member 76, and an adjustment screw 77 adjusts the gap between the movable contact and the fixed contact support member. The adjustment screw 77 and adjustment slot 73 allow the magnetically encoded card 11 to be cut to any desired length.

The clamping arm 61 has a protrusion 80, and when the relay 44 is excited, the clamping arm 61 moves downward and comes into contact with a movable contact 82 of the card drive reversal starting mechanism 81, so as to be described later. The reversible motor 36 is reversed to eject the cut card. The card drive reversal starting mechanism 81 includes a pair of lead wires 83,
It has 84.

3 and 3a respectively illustrate a smooth magnetically encoded magnetically encoded card 11,
11a is shown. The magnetically encoded card 11 shown in FIG. 3 is used in conjunction with the card acceptor 12 of FIG. 1 and has a continuous magnetically encoded magnetically encoded strip 91 at one end thereof.
Any magnetic code is electrically recorded on this magnetic coding strip. A magnetic code is selected that is compatible with the particular use of the card. If the encoded card does not have a code compatible with the acceptor's magnetic code reading mechanism, it will be rejected as explained below.

Each magnetically encoded card 11 records a numbered fare or fare portion 92, 93 which is separated by an acceptor. Since the card is numbered, the user can know how many times the card can be used. The magnetically encoded card in Figure 3 shows ten prepaid fares or charges.

What is shown in FIG. 3a is a magnetically encoded strip 9
In addition to la, a plurality of spaced apart magnetically encoded bands 94, 95, 96 are shown. If magnetic coded strips 94, 95, 96 are present, a second magnetic code reading head 56 is required to recognize the presence of any one or a combination thereof. Different information within the same application can be recorded on multiple magnetically encoded bands. For example, by deciding what to record on each of the multiple magnetic coded bands, you can record various types of information such as prepaid regular charges, prepaid elderly charges, prepaid disabled charges, prepaid student charges, etc. can be recorded separately, so even if there are a wide variety of fee structures, there is no need to issue various cards accordingly. When a magnetically encoded card 11a is used, a plurality of different codes on the card are read by the second magnetic code reading head 56, and the magnetically encoded card 11a is read as described for the magnetically encoded card 11 with respect to FIGS. 1 and 2. A similar operation is performed.

FIG. 4 is a diagram showing all functions necessary for operating the system according to the present invention.

As shown in FIG. 4, the system consists of a number of system components indicated by dashed lines. In Figure 4, the same reference numerals refer to Figure 1,
The same thing as FIG. 2, FIG. 3, and FIG. 3a is shown. The operation of the system is described below along with a description of the structure and circuitry.

The smooth magnetically encoded card 11 is partially inserted into a card presence detector 15 in the card acceptor 12, indicated by the dashed line on the outermost periphery, where the magnetically encoded card 11 is inserted into a pivotably supported switch mechanism. 9, the contact 9a is closed, completing a circuit from the battery to the lead wire 20, the contact 9a, the lead wire 25 to the relay 100, and the lead wire 101 to the ground of the system control means 99. This circuit activates relay 100 to close contacts a and b of relay 100, thereby completing a circuit to decoder 106 via lead wire 103, contact 100a, and lead wire 102. The decoder 106 is resettable so that a plurality of different acceptable code reading patterns can be easily created by manually switching a plurality of switches 105 indicated by arrows to any combination of 0 or 1. Decoder 106 is located near the hole in the card acceptor casing (not shown). By manually adjusting the fields of the decoder, it can be ensured that only encoded cards with card acceptors are selected.

In this way, decoder 106 can receive code signals from magnetic code reading mechanism 50. Further, the decoder 106 outputs the signal 11
0 to lead wire 109, back relay contact 113
a, lead wire 116, back relay contact 127
b, lead wire 117, back relay contact 136
b, lead wire 118, relay 120, lead wire 1
A series of circuits is completed by sequentially transmitting signals from 19 to ground. This circuit activates the relay 120,
Lead wire 121 from battery, front relay contact 1
20a, lead wire 60, relay 88 contact d, reversible motor 36, relay 88 contact b, lead wire 5
9, 59a, the circuit from the front relay contact 120b to the ground is completed. As the reversible motor 36 operates, the worm gear 37 rotates through the shaft 38, so that the rubber card drive wheel 23 is driven by the gear 18 in mesh with the worm gear 37. Magnetic coded card 1
1 is conveyed to a magnetic code reading mechanism 50 between a rubber card drive wheel 23 and an idler wheel 24 held by a spring. The reversible motor 36 has a reverse torque switch 66 on the shaft 38, which operates after reading by the magnetic code reading head 52 described herein and at the same time as the magnetic coded card 11 is cut to a predetermined length. It is activated when someone attempts to withdraw the magnetically encoded card before it is serviced by a device 86 that performs a predetermined service, which will be described later. The reverse torque switch 66 is connected to a reverse timer 68 by a lead wire 67.
The reverse timer 68 operates for a time sufficient to eject the card in the above case, and the lead wire 69 is energized. Lead wire 6
9 is a reverse drive relay 8 having contacts a, b, c, and d.
8 is connected. Contacts b and d of relay 88 are normally closed. When relay 88 is energized, contacts b and d open and contacts a and c are closed. Contact a
is connected to the battery, and contact c is grounded. With this configuration, when the relay 88 is activated, the motor 3
The rubber card drive wheel reverses its direction, causing a polar reversal at 6, and the magnetically encoded card 1
Eject 1.

Passage of the magnetically encoded card 11 between the magnetic code reading head 52 and the second spring supported idler 51 generates a signal on leads 53 and 54 which are connected to the decoder 106. When the code on the magnetically encoded card 11 is recognized by the decoder 106 as being good or acceptable, a signal 11 is sent to the lead 109.
0 is held, which causes reversible motor 36 to continue operating and feed magnetically encoded card 11 to card travel limit stop and card shear actuation mechanism 70.

If the detected code is bad or unacceptable, decoder 106 issues an output signal 111 on lead 108 and signal 110 disappears. When the signal 110 on the lead wire 109 disappears, the drive relay 120 is demagnetized and the reversible motor 3
The operation of No. 6 is interrupted.

Signal 111 on lead 108 activates good and bad code control relay 113, which is grounded at lead 114. The operation of the relay will be explained below.

The energized relay 113 opens its back relay contact 113a, which breaks the circuit to the drive motor relay 120 and simultaneously completes the reverse circuit through the reversible motor, reversing the direction of rotation of the reversible motor 36. . The card 11 is ejected by reversing the driving direction of the motor. The circuit that performs this reversal begins at the battery terminals, leads 122, and front control relay contacts 1.
13b, lead wire 59b, lead wire 59, relay 88 contact b, motor 36, relay 88 contact d,
Lead wire 60, back drive motor relay contact 1
This is a series of circuits from 20a to ground.

Once the code of the magnetically encoded card is recognized as being good or acceptable, the magnetically encoded card 11 is moved by the card drive means until it abuts the movable contact piece 74 of the card travel limit stop and card shear actuation mechanism 70. be moved forward. the result,
battery terminal, lead wire 78 passing through relay 136;
A circuit from the movable contact piece 74, lead wire 79, and lead wire 137 to ground is completed. This activates the relay 136, and the back contact 1 of the relay 136
36b and 136c are opened, and the Freon contact 136a
is closed, two circuits, namely, the circuit for operating the card drive means and the circuit for operating the magnetic card code reading mechanism, are simultaneously interrupted, and a third circuit (described later) is completed.

The circuit for operating the card drive means that is interrupted when the back contact 136b is opened includes the decoder 106, the lead wire 109, the back contact 113a of the relay 113, and the back contact 1 of the relay 127.
27b, lead wire 117, back contact 136b of relay 136 which is now open, lead wire 118,
This is a circuit from the relay 120 and lead wire 119 to ground. By opening the back contact 136b, the reversible motor 36 is stopped.

The circuit for the operation of the magnetic card code reading mechanism that is interrupted when the back contact 136c is opened is a connection circuit between the circuit from the lead wire 54 to the magnetic code reading head 52 and the lead wire 54a.

With the circuit shut off in the manner described above, the decoder 106 will not accept input after the magnetically encoded card reaches the end of its travel and the card shearing process described below will be performed.

Closing of the front contact 136a of the relay 136 completes the circuit from the battery terminal front contact 136a of the relay 136 to the lead wire 30, the relay 44, and the lead wire 29 to ground. Activation of the relay 44 causes the movable cutting member 62 to
The movable cutting member 62 lowers and cuts a portion of the magnetically encoded card 11 (not shown) between the movable cutting member 62 and the fixed cutting member 63.

The downward movement of the pincer arm 61 brings the protrusion 80 into contact with the movable contact 82 of the card drive reverse start mechanism 81, so that the movable contact 82 can be energized via the fixed contact 85, and as a result, the relay 127 is actuated. Then, the reversible motor 36 is rotated in the reverse direction, and the card with the corresponding fare or fee portion cut off is ejected.
At the same time, the device 86 is activated to perform a predetermined service. Card ejection after cutting is completed by a circuit of battery terminal and lead wire 83, fixed contact 85, movable contact 82, lead wire 84, lead wire 128, relay 127 and lead wire 129 to ground. Activation of relay 127 causes relay 100
Battery terminal and lead wire 104, front contact 1
00b, lead wire 131, front contact 127a of relay 127, lead wire 132, lead wire 59
A circuit is completed including lead wire 59, contact b of relay 88, reversible motor 36, contact d of relay 88, back contact 120a of relay 120, and ground.

In this way, the movable cutting member 62 of the clamping arm 61
At the same time that a portion of the magnetically encoded card is cut, the device 86 is activated to perform a predetermined service, while the cut card is ejected. In other words, if the card is not disconnected, the device will not operate and you will not be able to receive any service, so the service will be provided without reducing the value of the card (without the card being disconnected by the amount equivalent to the service provided by the device). After the card is read by the magnetic code reading head 52 to receive only the card, the card is removed before being serviced by the device 86 that performs a predetermined service, which operates at the same time as the magnetic coded card 11 is cut to a predetermined length. Even if an attempt is made to do so, the reverse torque switch 66 is activated and the card is immediately ejected, as described above, and no service can be provided. In this way, unauthorized use is prevented and cancellation is possible.

If a magnetically encoded card 11a is used,
The codes recorded on the card are read by the second magnetic code reading head 56 and operations similar to those described for the magnetically encoded card 11 with respect to FIG. 4 are performed.

〔effect〕

As explained above, the magnetically encoded card acceptor of the present invention can be installed in places where there are hard acceptors, mechanical coin slots, fare collection boxes in transportation systems, subway turnstiles, stadiums, and entertainment parks. It has the potential to be applied to countless applications such as machinery. Possible applications in gaming devices are pinball machines and electronic games. In addition, the present invention can be used in public telephones, self-service gas station pumps, amusement park rides, door access systems, etc. In yet another application, the system according to the invention can be used to operate gates in motor vehicle parking lots.

One of the features of the present invention is that prices can be set freely. Regardless of whether the system of the present invention is used for fare collection, vending, laundry machine rental, or telephone calls, the price of the card can be adjusted as desired. Since the card according to the present invention can be priced according to its purpose of use, it is particularly effective in areas where prices fluctuate rapidly and it is difficult to set prices. Embodiments of the invention can also be used to control sales volume. For example, if a gas station is forced to limit purchases due to a gasoline shortage,
When a purchaser inserts a card into a magnetic card acceptor, the gas pump dispenses the amount of gasoline corresponding to the price.

A unique advantage of the present invention is that it provides protection against unauthorized use. That is, if someone tries to pull out a card while the card acceptor is in operation, the reverse torque switch senses this and the card is ejected in the pulling direction.

A particularly important effect of the present invention is that it is possible to use a card with multiple codes recorded, so when there are many types of fee structures such as regular fees, elderly fees, disabled fees, student fees, etc. When used with a magnetic card acceptor system, a single card can accomplish its purpose by recording prepayment information for those charges on multiple magnetically encoded strips, making it possible to use multiple cards. do not have to.
