Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a state change sensor seal and a state change sensor seal assembly capable of automatically detecting unauthorized opening or unpacking of a sealed object, and more particularly, but not exclusively. Rather, the present invention relates to a pachinko game console base monitoring system using the same.

[0002]

2. Description of the Related Art In recent years, a pachinko game console is operated by a control program using a microcomputer for controlling the game console in order to change the game. The control program uses a program written in a read-only semiconductor memory (hereinafter referred to as a ROM).

As is well known, the operation of recent pachinko gaming machines is considerably improved in gambling, and has an operating state of "big hit". It has a reducing action. The control for realizing this operation is realized by the control program written in the ROM described above. Since this ROM is to be installed using a socket, a regular RO
It is possible to easily replace M with a ROM in which another program is written. If a person who understands the structure of a pachinko game console control program manufactures a ROM with a modified control program and replaces it with the original ROM, an unauthorized operation that discharges a large amount of winning balls will occur. It is possible to act.

[0004]

Conventionally, in order to eliminate such misconduct, a control board (board) equipped with a ROM is put in a case, and a special purpose is to prevent the case from being unpacked. It is obligatory to attach a suitable “sealing seal” to both threaded portions of the case or to the seams. This sticking is usually performed when the gaming machine is shipped from the manufacturer.

[0005] However, since this sealing seal is a "simple seal", if it is peeled off for an improper purpose, it can only be determined after an improper act has been performed.
In addition, since the determination can be made only by visual inspection, it is necessary to open all the gaming tables one by one and perform inspection.

The present invention has been made in view of such a conventional problem, and when a seal is illegally broken, a state change sensor seal capable of automatically detecting the seal without visual inspection. And a state change sensor seal assembly.

[0007] Another object of the present invention is to provide a pachinko gaming table capable of detecting an act in a substantially real-time manner when a state change sensor seal is broken, thereby preventing an illegal act from being executed. To provide a base monitoring system.

[0008]

SUMMARY OF THE INVENTION A state change sensor seal according to the present invention is a state change sensor seal attached to an object to detect that the object has been illegally opened or unpacked, A sheet having an adhesive applied to the back surface, a resistor or conductor pattern provided on the surface of the sheet, and first and second terminals for electrical connection provided at both ends of the pattern; Having a release paper that covers the adhesive surface of the back surface of the sheet and is removed at the time of use,
The pattern is damaged together with the sheet when the sheet is to be peeled off after being attached to the object.

As a result, the electrical characteristics of the present state change sensor seal change, and by detecting this change externally, it is possible to automatically detect that the seal has been broken without visual observation.

Preferably, printing is performed on the surface of the sheet so as to hide the pattern. This makes it impossible to immediately recognize the existence of the pattern.

In one embodiment, the sheet has an end having the first and second terminals close to each other;
An extension extending from the end, wherein the pattern is formed so as to extend inside the extension from the first terminal to the second terminal and to be folded back. By bringing the first and second terminals close to each other, the connection of the two wires can be performed at one place. Further, by forming the pattern so as to be folded back by extending the inside of the extension portion, the chance of breakage of the pattern can be increased when the seal is to be peeled.

By forming the sheet so that the side of the extension has a zigzag shape, the sheet can be easily broken when the seal is to be peeled off.

[0013] The sheet may be formed in a spiral shape in addition to the case where the extension portion is linear. Spiral makes it more difficult to peel off the seal without breaking it. Also, the material of the sheet is preferably formed of a material that is easily damaged.

In addition, in order to increase the possibility of breakage of the sheet, cuts may be formed in the side and intermediate portions of the extension.

A state change sensor seal assembly according to the present invention includes a state change sensor seal having any one of the above-described structures, an electrically insulating lower cover, and an electrically insulating upper cover that can be opened and closed with respect to the lower cover. First and second elastic conductive terminals fixed to either the lower cover or the upper cover, and engagement means for engaging the two covers with each other when the upper cover is closed with respect to the lower cover. , First and second wires having one ends electrically connected to the first and second elastic conductive terminals of the terminal box by pressing, and the first and second wires And a connector connected to the other end of the connector. This assembly allows for quick and easy installation and replacement of the condition change sensor seal of the present invention.

The pachinko game board base monitoring system uses any one of the state change sensor seals described above and affixes it to the target of detecting unauthorized opening or unpacking in relation to the pachinko game board base. The detected state change sensor seal, abnormality detection means for detecting a change in the electrical characteristic of the pattern between the first and second terminals of each state change sensor seal as abnormality, and the abnormality detection means Output means for notifying the user of the abnormality.

In this system, the abnormality detecting means can detect, as an abnormality, an electrical non-conduction state due to disconnection of the pattern of the state change sensor seal.
Alternatively, the abnormality detecting means can cyclically measure the resistance value of the pattern of the state change sensor seal, and detect when the amount of change in the resistance value exceeds a predetermined value as an abnormality.

The output means may have a calendar and a clock function, and output the date and time information when the abnormality is detected by the abnormality detecting means.

The output means is, for example, at least one of a display device, a printer, and an alarm device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

First, the appearance and structure of a state change sensor seal according to an embodiment of the present invention will be described with reference to FIG. FIG. 1A shows the appearance of the surface of the state change sensor seal 10. The state change sensor seal 10 includes a substantially rectangular base 11 and an extension 12 extending in one direction in a zigzag manner from the base 11. Terminals 13 and 14 for electrical connection are arranged on the base 11 in close proximity to each other. The terminals 13 and 14 are provided with holes 15 and 16 for positioning at the time of mechanical connection described later, respectively. The surface of the extension 12 is solid printed, for example, in black. Further, a character 19 of another color is printed thereon. Slits (cuts) 21 and 22 are provided in an intermediate portion between the zigzag V-shaped concave portion 18 of the extension portion 12 and the convex portion 17 corresponding to the concave portion 18. Convex part 1
7, a slit may be formed. Such a shape and slit make the paper 20 and a resistor pattern 25 described later easily break when the paper (sheet) 20 of the state change sensor seal 10 once applied is illegally peeled off. The purpose is not only to prevent reuse of the seal, but also to automatically and remotely detect the fraud.

As shown in FIG. 1B, a pattern 25 of a resistor (or a conductor) connected from the terminal 13 to the terminal 14 is provided below the solid printing of the extension 12.

As shown in the front view of FIG. 1 (c), the state change sensor seal 10 is a paper 2 having an adhesive applied to the back side.
And a release paper 26 which covers the adhesive surface of the paper 20 and is removed at the time of use.

As shown in the back view of FIG. 1 (d), the base 11 of the release paper 26 has a cut 2
7, 28 are provided to facilitate release of the release paper 26 during use.

The manufacturing process of the state change sensor seal 10 is as follows.

First, a large sheet made of such paper 20 and release paper 26 is prepared. As the paper 20, a film made of a material that is not easily broken by a normal seal is used, whereas a sheet made of a material that is easily broken is used in the state change sensor seal 10. In this embodiment, paper formed of pulp is used as such a sheet.
Any material other than paper can be used as long as it is easily broken and can print or cover the resistor pattern 25 on the surface.

Next, as shown in FIG.
A plurality of resistive (or conductive) patterns 25 on 0
Print. In this embodiment, a resistor obtained by mixing carbon and silver at a predetermined ratio (for example, 3: 1) is used. The reason why silver is mixed is that the resistance value of the pattern 25 is unstable with only carbon, and this is stabilized. The resistance value of the pattern 25 in the present embodiment is on the order of 1 k to several k ohms. In the example of FIG. 1, the resistor pattern 25 is
The wire extends in a zigzag shape in one direction, is folded, and returns to the terminal 14 so as to be parallel to the previous line.

The pattern 25 may be formed by applying a patterned conductor foil instead of such printing, for example.

Next, the base 11 is placed on the pattern 25.
In a state where the terminals 13 and 14 are exposed, solid printing is performed using, for example, black ink. This is to hide the pattern 25 and protect the pattern 25. If necessary,
Further, the character 19 is printed thereon with another color ink.
Instead of this, the character 19 may be formed simultaneously with the solid printing by blanking out the black solid printing.

Next, a seal is cut out along the outer edge of the pattern 25. At this time, the slits 21 and 22 and the cuts 27 and 28 are also formed. In this way, a number of state change sensor seals 10 are completed simultaneously.

FIGS. 2, 3 and 4 show modified examples of the state change sensor seal according to the present invention. FIG. 2 shows a spiral shape of the extension 12 and the pattern 25, and a slit 18 is formed on the periphery of the extension 12. FIG.
The extension 12 and the pattern 25 extend linearly,
The width of the extension 12 is repeatedly increased and decreased. A slit 22 is formed in a narrow portion of the extension portion 12. FIG. 4 is similar to the configuration of FIG.
Is a rectangular shape, and a V-shaped cut 19 is formed intermittently on the side. A slit 22 is provided in an intermediate portion corresponding to the cut 19.

FIG. 5 shows a state change sensor seal assembly 30 using the state change sensor seal 10 shown in FIG.
Is shown. One ends of wires 68 and 69 are electrically connected to the terminals 13 and 15 of the state change sensor seal 10 by known means such as screwing. A connector 77 for connection to an extension cable is connected to the other ends of the wires 68 and 69.

FIG. 6 shows an electric circuit configuration using the state change sensor seal according to the present invention. Electrically, one end of the resistor 32 formed by the pattern 25 of the state change sensor seal 10 is connected to one end of the pull-up resistor 31, and the other end of the pull-up resistor 31 is connected to the power supply terminal 33. On the other hand, the other end of the resistor 32 is connected to the ground potential 34. The voltage at the connection point 35 between the pull-up resistor 31 and the resistor 32 is monitored by a method described later. The resistance 32 actually includes the resistance of the pattern 25 as well as the wiring resistance of the wires 68 and 69 and the cables ahead thereof.

In the state change sensor seal assembly 30 of FIG. 5 described above, the terminals 13 and 15 remain exposed to the outside. By electrically connecting the terminals 13 and 15 with a jig such as a clip, the sensor can be disabled.

As a means for eliminating such a possibility, FIG. 7 shows a terminal box 50 for mechanically and electrically connecting wires 68 and 69 to the base 11 of the state change sensor seal 10.

As shown in FIG. 7A, the terminal box 5
0 has a lower cover 61 and an upper cover 60 that opens and closes around one side 55 of the lower cover 61. Both covers,
It is formed of an electrically insulating material such as plastic. Hooks 57 are provided on both sides of the upper cover 60. Both hooks 57 constitute an engagement means, and the upper cover 60
When the cover is closed, it engages with the hook hole 61 of the lower cover 61. The upper cover 60 can be opened by releasing the engagement while pressing the hooks 57 from the side. Elastic conductive terminals 51 and 52 to which wires 68 and 69 are soldered are fixed to the upper cover 60, and a pedestal 6 having projections 64 and 66 to the lower cover 61, respectively.
Reference numerals 3 and 65 are provided at positions corresponding to the elastic conductive terminals 51 and 52. The roles of the upper cover 60 and the lower cover 61 may be reversed. With the upper cover 60 opened, the holes 15, 16 of the base 11 of the state change sensor seal 10 are aligned with the projections 64, 66 of the lower cover 61 of the terminal box 50, and the upper cover 60 is closed. , FIG.
State change sensor seal assembly 3 as shown in FIG.
1 is completed. Thereby, the effect that the installation and replacement of the state change sensor seal can be performed quickly and easily can be obtained.

The cores of the wires 68 and 69 are simply connected to the elastic conductive terminals 51 and 52 only by pressing. When the upper cover 60 is opened, the wires 68 and 69 and the terminal 1 are connected.
The electrical connection with 3, 14 is disconnected or incomplete. Thereby, when the terminal box 50 is opened illegally, this is detected as an abnormal state of the sensor as described later.

Next, as an example of using the state change sensor seal of the present invention, a case where the seal is used for detecting and preventing fraud in a pachinko hall will be described.

FIG. 8 shows the appearance of a base case 71 in which a base on the back side of the pachinko game board 70 is stored. Sealing seal 73 for sealing cover 72 of base case 71
Are affixed on the screws fixing the cover 72. On the other hand, for example, the state change sensor seal 1 of the state change sensor seal assembly 30 shown in FIG.
0 (paper 20) is attached so as to straddle between the base case 71 and the cover 72. The wires 68 and 69 are fixed at predetermined positions on the game board 70 by wire stoppers 75,
7 is connected to an external connector 78. An unauthorized person attempts to open the cover 72 to replace the ROM inside the base case 71, and
Even if the user tries to remove 0, the specially formed paper seal as described above will be broken. This damage is detected as an abnormal state of the sensor by an electric circuit described later. FIG.
The reference numeral 74 shown in (1) denotes a motor for repelling pachinko balls. Here, an example in which the state change sensor seal 10 is attached to one pachinko game board 70 at one place is shown, but a plurality of state change sensor seals 10 may be attached to a plurality of places.

Similarly, the state change sensor seal assembly 31 with the terminal box 50 shown in FIG.
It is used as shown in FIG.

Referring to FIG. 10, it is conceivable that an unauthorized person may replace the ROM for each board with respect to the connector 80 for connecting control signals provided outside the case 71 of the pachinko board 81, instead of replacing the ROM. . To deal with such irregularities, the state change sensor seal 10 can be attached so as to straddle the joint surface of the connector 80. Although the example of FIG. 10 shows an example in which the state change sensor seal assembly 31 with the terminal box 50 is used, the state change sensor seal assembly 30 of FIG. 5 may of course be used.

FIG. 11 shows a schematic configuration of a pachinko game board base monitoring system using the state change sensor seal of the present invention. In this system, a plurality of sensor monitoring terminal devices (monitoring switching devices) 93 that cyclically monitor a group of state change sensor seals 10 are connected to each other via a communication network line (communication line) 95. The sensor monitoring host device 92 includes a printer 91 and an alarm generating device 90 connected to the host device 92. The alarm generating device 90 shows an alarm lamp in the example shown in the figure, but may alternatively or additionally generate an alarm sound. In the pachinko hall, a group of game consoles is provided for each block called an “island”, and a terminal device 93 is provided for each of the islands. The host device 92 and the plurality of terminal devices 93 are connected by a serial connection type communication line. Each terminal device 93 executes a predetermined operation described later in accordance with an operation command of the host device 92 via the communication line.

Next, the detailed structure and operation of each device will be described.

FIG. 12 shows an example of the internal configuration of the sensor monitoring terminal device 93. Each state change sensor seal 10 is affixed to a base case or the like of a pachinko game console as described above, and detects a change in electrical characteristics due to the destruction of a sensor when the base case is unpacked. Is detected. The terminal device 93 includes a sensor switch 931, a state determination circuit 935, and a sensor information communication network circuit 93.
And 7.

The sensor switch 931 is a circuit for realizing an electrical switch switching function for selectively connecting the outputs of the plurality of state change sensor seals 10 to the state determination circuit 935, and specifically, for example, a multiplexer. Can be used. Normally, the switch 931 is used with several tens of state change sensor seals 10 connected thereto.

The state determination circuit 935 sends a switching control signal 932 of the state change sensor seal 10 to the sensor switch 931 to determine a change in electrical characteristics due to the destruction of the sensor selected by the sensor switch 931. Circuit. Specifically, an analog-to-digital converter (not shown) that converts an analog voltage output of the sensor switch 931 into a digital value for each state change sensor seal, and receives a digital output of the analog-to-digital converter to perform a determination process. And a processor circuit (not shown). However, the present invention is not limited to these specific configurations.

The switching operation and determination of the state change sensor seal of the state determination circuit 935 are sequentially and continuously executed for all the state change sensor seals, and this operation is circulated. Since the circulating cycle time for determination of all state change sensor seals is several seconds, monitoring in almost real time (real time) becomes possible. Then, as a result of the determination, the information of the sensor number (or the machine number of the gaming machine) and the state information are transmitted to the sensor information communication network circuit 937. There are the following two methods for determining the state of the sensor of the state change sensor seal realized by the terminal device 93.

(A) A method of determining that an electric switch is opened by disconnecting a current caused by a break in an electric conductor provided on the sensor surface due to destruction of the sensor. The advantage of this method is that it can be realized at a low cost even if the number of state change sensor seals is large, because the structure is simple.

(A) Electrical resistor pattern 25 provided on the sensor surface due to destruction or breakage of the sensor
A method of measuring a change in the resistance value of the above and determining whether the change amount exceeds a predetermined value. According to this method, since the determination can be made by successively comparing the resistance value of the state change sensor seal of the same number measured in the previous circulation of this determination processing, the resistance against a gradual change such as a change with time of the resistor can be obtained. It is possible to change the value determination range. As a result, there is an advantage that the same sensor can be used for the determination with high accuracy for a long time even when the accuracy of the determination specified value is increased. Furthermore, when the state change sensor seal is used as a resistor, it is possible to determine the state change sensor seal in a partially damaged state, as compared with the case where the state change is determined only in the destruction state. Have. Further, the clip between the terminals 13 and 15 described above can be dealt with.

Sensor information communication network circuit 937
Responds to the request of the digital communication signal from the host device 92 with the information of the specific state change sensor seal received from the state determination circuit 935, and stores the state information of the state change sensor seal generated since the previous communication in the host. Transmit to the device 92. This communication is performed cyclically to enable near real-time abnormality detection.

FIG. 13 shows an example of the internal configuration of the sensor monitoring host device 92. The host device 92 includes a data processing control circuit unit 921, a clock circuit 922 that outputs date and time data, a memory unit 924 that stores monitoring information history of each state change sensor seal, and a sensor communication information network control circuit unit 923. Having. The host device 92 is configured by the same hardware as a normal computer. The data processing control circuit section 921 includes an alarm device 90 such as the above-described alarm lamp, a printer 91 for print output, a display device (LCD panel) 94 for displaying various information, and a user for performing various inputs. Is connected. The data processing control circuit unit 921 may be provided with an input / output terminal 97 for communicating with another data processing device.

The data processing control circuit section 921 performs all control of the present apparatus. The control circuit section 921 converts the state information of each sensor obtained from the sensor monitoring terminal device 93 through the sensor communication information network control circuit section 923 into an LCD.
The information is transmitted to the panel 94, the printer 91, the alarm generation device 90, and the monitoring information storage memory unit 924 to realize processing necessary for the operation of the present system.

Sensor communication information network control circuit 9
23 is provided from the following viewpoints. In other words, the state change sensor seal that must be monitored by the present system must be installed at a place that is considerably far from the place where the host device 92 is installed. In addition, the total number of the state change sensor seals usually requires several hundreds or more. From these requests, the sensor monitoring terminal 93
Are required, and it is necessary that each of them can be installed at a distance. For the purpose of satisfying these conditions, the present system is provided with a network mechanism for connecting the host device 92 and the terminal device 93 by a data communication line and mutually efficiently communicating data.

The monitoring information history storage memory unit 924 is provided from the following viewpoint. That is, in the present system, since a special type of destructive sensor is used for the state change sensor seal, when an abnormality occurs in the sensor, repair by replacing the sensor is indispensable. The situation in which the sensor has caused an abnormal state is indicated by the L
The status is displayed on the CD display unit, and at the same time, the status is printed out on the printer 91. The monitoring information history storage memory 924 is provided for the purpose of using the information more effectively.
This makes it possible to reuse the information on the occurrence of the monitoring abnormality later. As the monitoring information history storage memory 924,
A non-volatile data memory is used that can retain the stored contents even when the power supply to the memory is cut off. For example, such data non-volatile memory includes:
A hard disk, a flash memory, a battery backup RAM, or the like can be used.

The clock circuit 92 has a sensor monitoring terminal 93
It is used to add date and time of occurrence data to the data in order to improve the accuracy of the data information obtained from.

The control switch unit 96 is provided for the purpose of giving an instruction such as processing operation setting of the present system.

The printer 91 is provided for the purpose of informing the administrator of the apparatus of the status of each sensor and the state of the apparatus itself as print character information.

FIG. 14 is a flowchart of a terminal process for sensor monitoring, which is executed by each terminal device 93 cyclically. Although depending on the total number of all state change sensor seals, the normal circulation time for the determination is within several seconds.

First, the variable i for repetition is set to 1 (S140), and the process enters a subsequent repetition loop. The variable i is
It is also a serial number of the state change sensor seal belonging to the terminal device 93. When one state change sensor seal is used for each gaming table, the variable i can be regarded as a table number. In the repetitive loop, first, it is checked whether or not the i-th sensor is in an abnormal state (S141). This specific example will be described later. Next, if there is no problem in the check result, that is, if a variable alarm (i) to be described later is 0 (No in S142), the process proceeds to step S144. If the variable alarm (i) is 1 (Y in S142)
es) It is necessary to report to the host device 92. The current time, the sensor number i, and the sensor status information (here, “abnormal”) are stored in a memory (not shown) in the status determination circuit 935.
(S143).

Although the terminal device 93 shown in FIG. 12 does not include a clock circuit, each terminal device 93 receives real-time time information from the host device 92 and divides the time within itself. This allows all the terminal devices 93 to synchronize the time with the host device 92.

Next, the previous sensor check processing S141
If it is confirmed that the alarm (i.e., alarm (i)) is once restored (natural or due to sensor replacement) (that is, resume (i) = 1) (Yes in S144), The current time, the sensor number i, and the sensor state information (here, “recovery”) are stored in the state determination circuit 9
35 and temporarily stored in a memory (not shown)
esume (i) is reset to 0 (S145). r
If esume (i) = 0 (No in S144), the process jumps to step S146. When there is a data transmission request from the host device 92 (S146), the untransmitted storage data is transmitted to the host device 92 and reported (S147). Thereafter, the variable i is incremented (S148), and if the variable i does not exceed its maximum value imax (S14).
9) Returning to step S141, the next sensor is checked. If it exceeds the maximum value imax, the current terminal processing is terminated.

FIG. 15 shows an example of the sensor check process (S141) of FIG. In this example, first, it is checked whether alarm (i) is 1 for the sensor (S151). Initial value of variables such as alarm (i) is 0
It is. If alarm (i) is 0, step S15
Proceed to 2 and if it is 1, proceed to step S154. In step S152, the electrical continuity of the sensor is checked. If the continuity is confirmed, it is determined that there is no abnormality, and the process ends with the variable alarm (i) functioning as a flag being 0. On the other hand, if continuity is not confirmed, it is determined that an abnormality has occurred and the variable
m (i) is set to 1 (S153). Step S15
At 4, it is checked whether the sensor has been restored (here, whether the sensor has returned to the conducting state) (S154). If the restoration is confirmed, the variable resume (i) is set to 1 (S155), and a
The alarm (i) is returned to 0 (S156). If the restoration is not confirmed, nothing is performed and this processing ends.

FIG. 16 shows the sensor check process S of FIG.
141 shows another example. In this example, the resistance value is measured for the above-described purpose, instead of simply checking whether the sensor is conducting or not conducting. First, the resistance value of the sensor measured this time is set as a variable c (i) representing the current resistance value of the i-th sensor (S161). Next, it is checked whether alarm (i) is 1 for the sensor (S162). If 0, step S16
The process proceeds to step 3, and if it is 1, the process proceeds to step S167. In step S153, the value of the variable p (i) representing the previous resistance value of the i-th sensor is compared with the value of the variable c (i) (S163). The absolute value of the difference between them is a predetermined threshold Th
Is exceeded, the amount of change over time is too large, so it is determined that an abnormality has occurred, and the variable alarm (i)
Is set to 1 (S164). If it does not exceed Th, step S164 is omitted and the process proceeds to step S165. In step S165, the current value of the variable c (i) is substituted for the variable p (i) for the next process (S16).
5) This sensor check ends.

Although not shown, at this time, a new p (i)
If the value reaches a predetermined upper limit value or lower limit value, for example, even if alarm (i) is 0, it is determined that the sensor has deteriorated to the limit value, and the host side is notified of the fact. A report may be made to prompt the exchange of the sensor.

In the previous step S162, alarm (i)
Is equal to 1, the same check as in step S163 is performed (S166). However, it should be noted that the variable p (i) is not updated while alarm (i) is 1. If the absolute value of the difference between the value of the variable p (i) and the value of the variable c (i) does not exceed the predetermined threshold Th,
The variable resume is determined to have been restored to the normal state.
(I) is set to 1 (S167), and alarm (i) is set.
Is returned to 0 (S168). If the threshold value Th is still exceeded, the process is terminated without doing anything. Note that the variable p
The initial value of (i) is a representative value (for example, a design value) within a normal range of the resistance value of the sensor.

Finally, a processing example of the host device 92 will be described with reference to FIG. This host process is also executed cyclically.

First, the variable j of the repetition is set to 1 (S1
71), the following loop processing is performed. This variable j corresponds to the number of the terminal device 93.

In the loop processing, first, a request for transmission of data relating to sensor monitoring is made to the j-th terminal device 93 (S172). The data from the terminal device 93 is received by a buffer memory (not shown) (S173). If the occurrence of a state change is confirmed from the received data (S1
At 74, an alarm signal is generated to the alarm device 90 (S175). The state change here includes "abnormal" and "recovery". Preferably, the form of the alarm is different between “abnormal” and “recovery”. For example, the display mode of the alarm lamp is changed, or the generation mode of the alarm sound is changed. Next, the received data is displayed on the LCD panel 94 and printed out to the printer 91 (S176). Further, the data is additionally stored in the table 925 in the monitoring information history storage memory unit 924 (S177). In this table 925, the terminal number j, the sensor number i, the date and time data, and the sensor state (here, “abnormal” or “recovery”) are recorded as one record. When only “abnormal” is inspected as the sensor state, the “state” column of the table 925 is unnecessary.

If the occurrence of a state change is not confirmed in step S174, the process proceeds to step S178.

In step S178, the variable j is incremented, and it is checked whether the variable j has exceeded the maximum value (step S178).
179). Until the maximum value is exceeded, the process returns to step S172 and repeats the above loop processing for the next terminal device 93. If it exceeds the maximum value, the process returns to step S171, and the above processing is executed cyclically.

Although the preferred embodiment of the present invention has been described above, various changes can be made without departing from the gist of the present invention.

For example, in the above description, data is transmitted from the terminal device 93 to the host device 92 only when there is a data transmission request from the host device 92. However, in the terminal device 93, a sensor abnormality is detected. At this time, the fact may be immediately reported without a request from the host device 92. In addition, the case where it is used for detecting and preventing fraudulent use in a pachinko hall has been described as an example. Can be applied to

According to the state change sensor seal and the state change sensor seal assembly of the present invention, when a seal is illegally broken, it can be automatically detected without visual inspection. As a result, fraudulent acts can be quickly found. Further, when the sensor seal is broken, the act can be detected almost in real time, and it is possible to prevent the illegal act from being executed.
