DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate system such as an entrance / exit control device for passing an owner of a proper information record to a ticket gate, a specific building / facility, or a specific place in a railway. The present invention relates to a gate system in which two types of information recording materials having different positions to be presented are processed together.

[0002]

2. Description of the Related Art Ticket gates that permit or block the passage of passengers on railroads, and the passage of entrance and exit people so that only specific persons can enter and exit important places such as confidential buildings and specific rooms. Alternatively, a mechanized gate system is frequently used at a predetermined entrance / exit portion, such as an entrance / exit management device for preventing the entrance / exit. Conditions that permit passage include:
In some cases, fingerprints, voiceprints, bills, and the like are checked, but more generally, specific information is recorded on an information recording medium (information recording material) such as a magnetic card or an IC card, and is presented (inserted into an apparatus or inserted). The recorded content of the recorded information is read by a gate device to check whether or not the recorded information is correct. If the information is correct, the presenter passes through the gate device. Permitting devices have become widespread and are used in large numbers, particularly as automatic ticket gates.

[0003] Among the above-mentioned information recorded materials, the magnetic card or the like is inserted into a gate device or the like once, and the recorded information is read at a predetermined portion while being conveyed inside the gate device. It is to be returned to the owner (hereinafter, this method is also referred to as contact type). However, in order to improve the usability of an information recorded material such as a magnetic card, that is, it is only necessary to present the information recorded at a fixed position while being held by a passerby, and to use a large amount of recorded information. Gate system (hereinafter, also referred to as a non-contact type) is required.

Inevitably, it is required to process the two types of information recording materials of the contact type and the non-contact type, for example, both a magnetic card and an IC card by a single gate device, and development has been made. FIGS. 4 and 5 show an automatic ticket gate 20 which is an example of a gate device for processing such two types of information recording materials of a contact type and a non-contact type, that is, both a magnetic card and an IC card. It shows a plan view and a side view.

The automatic ticket gate (gate device) 20 is a flap type gate device, and gate devices 1, 1 'are erected on both sides of entrances A and B provided at a ticket gate of a station. I have. The gate devices 1 and 1 'are provided with passage preventing doors 2 and 2', respectively, which are rotatably protruded to the side of the entrance and exit on the side surfaces and are capable of blocking the passage of pedestrians.

[0006] At the entrance side of the upper surface of one of the gate devices 1 (ie, near the entrance), an insertion slot 4 for inserting a magnetic card (commuter pass or the like) 3 on which check information or the like is recorded.
A well-known transport path (not shown) is provided inside the apparatus so as to be continuous with the insertion port 4. A read magnetic head 6 (not shown) for reading information recorded on the magnetic card 3 is provided along the transport path, and its output is connected to a magnetic information reading unit 7. That is, the first information reading unit 5 including the reading magnetic head 6 and the magnetic information reading unit 7 is provided. The information signal of the magnetic card converted into a predetermined electric signal by the magnetic information reading unit 7 is input to the determination control unit 12. Reference numeral 8 denotes a return port provided at the front of the upper surface of the apparatus following the end of the transport path for returning a processed magnetic card to a passer (if necessary).

Further, at a position near the middle of the upper outer surface of the gate device 20 near the entrance, that is, at a position forward of the magnetic card insertion port 4 in the approach direction of the entrance / exit path, check information and the like are recorded in the same manner as the aforementioned magnetic card. An IC card (commuter pass, prepaid pass, etc.) 9 is provided with a presentation unit 10 for presenting information for reading. The verification information obtained by the presentation unit 10 is converted into a predetermined electric signal and input to the subsequent second information reading unit 11. The signal from the second information reading unit 11 is also input to the determination control unit 12.

The determination control unit 12 housed inside the gate device 20 determines whether or not the passage of a pedestrian is proper based on the information from the two types of objects to be checked (3, 9). Then, the passage blocking doors 2 and 2 'are driven and opened to permit passage or closed to block passage. That is, information signals from the outputs of both the magnetic information reading unit 7 and the second information reading unit 11 are input to the determination control unit 12, and are processed to process passage suppression only when the information content is appropriate. The doors 2 and 2 'are controlled to be opened to permit the passage of the passerby through the gate device, and when the information record is invalid, the pass-inhibiting doors 2 and 2' are opened to prevent the possessor from passing. Control and close this. In addition, W is a partition for prohibiting entry and exit from other than the gate portion.

[0009]

By the way, this type of conventional apparatus including the exemplified apparatus, that is, the information recording material (sometimes referred to as a contact type) conveyed as described above and presenting at a fixed position In a gate device using two types of information recording materials, which are not conveyed and are not conveyed (often held in a hand in a non-contact manner), which are subjected to a review of information, the structure of each part at present, space saving, etc. In accordance with the request described above, the information recording material presentation position (in the case of a transport type, which means the insertion position) at which the information recording material holder inserts or presents two types of inspection objects in the passage, respectively, is different. That is, in the present situation, as described above, the presentation (insertion) unit is provided at the position in front of the magnetic card insertion slot 4 in the entry / exit direction with respect to the entry / exit path, as in the case of the magnetic card. An IC card (commuter pass, prepaid pass, etc.) 9 is provided with a presentation unit 10 for presenting information for reading. Because of the positional relationship, when presenting (inserting) a magnetic card, the passer inserts it at the position immediately before the passage, while when presenting an IC card, the holder is placed at the very center of the passage. The presentation is made at a position that has been advanced to.

[0010] The conventional gate device judges the recorded information when any of the information recorded materials is presented, and when the result of validity is obtained, immediately permits the passage without discriminating the type of the information recorded material. Control. As a result, when a large number of passengers carrying either the contact type or the non-contact type information record try to pass through the gate device in various orders and in close proximity, the following inconvenience occurs. .

That is, as shown in FIG. 7, when the preceding customer FP and the following customer RP continuously pass through the gate device 1,
The four cases shown in the table can be considered depending on the information recorded materials possessed by each of them, and (a) to (c) are usually processed in the order of presentation as shown in FIG. There is no risk of the processing order being changed. However,
In the case of (d), that is, as shown in FIG. 6, the customer FP (preceding customer) of the non-contact type information recording (IC card) 9 and the customer RP (subsequent) of the contact type information recording (magnetic card) 3 Customer)
However, a problem arises when trying to pass through the gate device 1 in this order.

In this case, based on the above-mentioned difference in the position of the presenting unit (input port 4 and presenting unit 10), depending on the timing of the presenting operation of each passing customer, as shown in FIG. There is a possibility that the order of the obtained presentation information / check result is replaced with the approach / progress order of the presenting customer, and the process corresponding to the succeeding customer RP may be performed first.

For example, the customer F of the preceding IC card 9
Before the P performs the presenting operation, it is possible for the possessor RP of the magnetic card 3 following the passenger to insert the magnetic card 4, and in this case, information recording of the magnetic card possessor RP located behind. The magnetic card 4 as an object is conveyed through the conveyance path and is subjected to information reading processing, and the result of checking whether the card is a valid ticket is input to the determination control unit 12 first, and the corresponding predetermined processing is also performed. Would be. That is, they are interchanged.

In addition, when the customer of the preceding IC card 9 takes time to present or the presentation method is not appropriate, for example, when the information from the IC card 9 cannot be obtained, the subsequent magnetic card 3
It is fully considered that the input from the passenger will be performed, and the same check information and the passenger to be checked are replaced.

[0015] If the order of the obtained presentation information is reversed with the approaching order of the presenting customer, for example, if the magnetic card of the succeeding customer is determined to be an invalid ticket inside the apparatus first, the gate device will turn to the invalid ticket. , The door is closed and the passage of passers-by is stopped. In this case, although the preceding customer presents the valid ticket, the passage is unduly blocked, resulting in confusion.

If the succeeding customer's magnetic card is first presented (inserted) and determined to be a valid ticket, even if the preceding customer's IC card presented later is invalid, it is different from the fact. The first passenger presents the valid ticket, the second passenger presents the invalid ticket, and is processed as if the invalid ticket was presented. The preceding passenger of the invalid ticket is allowed to pass unfairly, while the succeeding passenger of the valid ticket has the invalid ticket. Inconvenience occurs when traffic is blocked as a person.

[0017] In addition, if the difference between the passing order and the presentation order of the information recording material is not sensed and corrected, the contact-type information recording material (magnetic card 3) is temporarily separated from the owner's hand and the device is removed. The magnetic card 3 inserted by the subsequent customer is returned at a timing that can be received by the preceding customer, but the return process must be returned to the proper owner. It is a problem that the leading customer may take away the magnetic card owned by the following customer. In order to prevent this, it is conceivable to take measures such as sensing the change of the order of passing the customers and the order of presenting the information recorded material and delaying the return of the magnetic card accordingly, etc. It is necessary to sense the permutation of the order.

As described above, in the gate device in which the contact type and the non-contact type information recording material are mixed, there is a possibility that the check information and the passenger to be checked are interchanged, and in this case, various inconveniences occur. . The present invention has been made in order to cope with such a situation, and appropriately detects the change of the processing order of the check information and the order of the check target passengers and reflects the above-described problems in the subsequent processing. It has been made to propose a gate device that can prevent the problem.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. The gate system of the present application has almost the same configuration as that of the conventional gate system described above, and differs only in the determination control part. Therefore, the automatic ticket gate 2 shown in FIGS.
0 is also an embodiment of the gate system of the present invention.

The outline of each part of the automatic ticket gate 20 which is also an embodiment of the present application will be simply repeated with reference to FIGS. 1 and 2.
An automatic ticket gate (gate device) 20 is provided with gate devices 1, 1 'provided on both sides of entrances A and B provided at a ticket gate portion of a station. Doors 2 and 2 'which can prevent the passage of a person, and the entrance side of the upper surface (that is, near the entrance).

And a return port 8 for a magnetic card is provided at the rear of the upper surface of the apparatus.

A transport path (not shown) is provided inside the apparatus and extends from the insertion port 4 to the return port 8. A first information reading section comprising a read magnetic head 6 and a magnetic information reading section 7 is provided along the transport path. 5 are provided. The output of the magnetic head 6 is input to the magnetic information reading unit 7, the output of the presentation unit 10 is input to the second information reading unit 11, and the outputs of the first information reading unit 5 and the second information reading unit 11 are both determined. It is input to the control unit 12.

By the way, in the conventional apparatus, the judgment control unit 12
As described above, if there is an input, a check is immediately performed in response to the input, and processing according to the check result is performed. However, according to the present invention, the temporal relationship between the respective inputs is considered. It is configured to be able to determine. Hereinafter, the determination control unit 12 of the embodiment device will be described in detail.

FIG. 1 is a block diagram showing one embodiment of the present invention. The determination control unit 12 checks whether or not signals from both the magnetic information reading unit 7 and the second information reading unit 11 are input and the record information of the information record 3 or 9 (check object) is valid. A determination circuit 13, a timer circuit 15 for inputting time information to the determination circuit 13,
And a control circuit 14 for driving a door via a door opening / closing circuit 17 in accordance with the determination result, or for displaying an appropriate instruction or the like on a display 18 via a display circuit 16.

The determination circuit 13 immediately performs a checking process in response to an input from the second information reading unit 11 corresponding to the presentation of the IC card 9 and outputs the same to the control circuit 14. A predetermined process corresponding to the result is performed. However, the magnetic information reading unit 7 corresponding to the insertion of the magnetic card 3
In response to an input from the (first information reading unit 5), a predetermined process replacement possible time is set for a predetermined time Tc based on the output of the timer circuit 15, and the IC card 9 is presented. If the IC card 9 is not presented during this time, the checking process of the magnetic card 3 is started after a predetermined time Tc has elapsed, and the result is sent to the control circuit 1.
4 and the control circuit 14 performs a predetermined process according to the contents of the check of the magnetic card.

However, if the IC card 9 is presented during the above-mentioned standby, that is, within a predetermined time Tc after the insertion of the magnetic card 3, the control corresponding to the previously performed check of the magnetic card 3 is immediately canceled. Inspection of the IC card 9 and control according to the result are performed, and thereafter control according to the inspection result of the magnetic card 3 is performed again. FIG. 7 already shown in FIG.
FIG. The description of the cases (a) to (c) is substantially the same as that described above, and thus will be omitted.

Then, as shown in (d) of the table of FIG.
In the case where the follower RP having the magnetic card 3 approaches the preceding FP having the C card 9 and passes through the gate device 1 (see also FIG. 6), particularly, as shown in FIG.

As a result, the order of the passers-by and the order of the checking and processing of the checking object owned by the passing person can be avoided, and the original purpose is achieved.

FIG. 3 is a flowchart showing an example of the processing steps of the above embodiment. In brief, at the start of the operation, the first input from any information reading unit is determined (S
1, S2), counting by a timer is started (S3), and after processing (S4) based on the output of the determination result is performed, an input from any of the information reading units is monitored (S5). Is determined and output (S6), and it is determined whether a predetermined time (Tc) has elapsed since the previous input (S6).
7) If the time has not elapsed, time measurement by the timer is started (S8), and at the same time, the passage permitting / blocking process currently being output is canceled (S9), and a process based on the present determination result is performed (S10). Then, the passage permitting / blocking process canceled in the previous step S9 is performed again (S1).
1) After that, monitoring of the input from any of the information reading units (S5) is repeated. In addition, as a result of determining whether or not a predetermined time (Tc) has elapsed since the previous input (S7), if the predetermined time (Tc) has not elapsed, time counting by a timer is started (S3). The process (S4) based on the output of the determination result is immediately performed, and thereafter, monitoring of the input from any of the information reading units (S5) is repeated.

The above-mentioned predetermined time Tc is slightly different from the optimum value depending on the difference of the gate device (the position dimension of the input unit and the presentation unit) and the moving speed of the passer. A fixed appropriate value may be selected in consideration of the usage status such as the time zone, or the respective components may be easily changed and operated while changing according to the time zone by a predetermined program.

In the present invention, the point is that the judgment control unit
Within a predetermined time after the signal input from the information reading unit (magnetic card reading unit), it is detected whether or not there is an input from the IC card from the second information reading unit. It is only necessary to add a function of performing processing corresponding to the input from the second information reading unit first, and then performing processing corresponding to the input from the first information reading unit.

As described above, the gate device of the present invention has been described as an example of an automatic ticket gate that handles both a magnetic card and an IC card. However, the application of the present invention is not limited to the automatic ticket gate. In general, passers-by correspond to both transport-type information recordings (confirmation objects), which record the predetermined reference information, and transport information reading and writing, and non-conveyance-type information recording materials (conveyance objects) that do not require transport. The transport-type information having a determination control unit for checking or presenting any of the presented inspection objects and permitting or blocking the passage of the pedestrian in accordance with the inspection result, and which is disposed in a portion close to an entrance of the apparatus.

A presentation unit for the formula information record,
In various gate devices having a second information reading unit for processing a signal from the presenting unit, the order of progress of the presenter and the replacement of the checking result obtained from the checking object are the same as those described above. Can be widely applied to solving problems. For example, the device itself may be an on-site monitoring device for a specific location, or the second inspection object may be a connector type (contact type) IC card or a non-transport type that passes through a slit-shaped reading unit while being held by hand. It may be a magnetic card.
