Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product opening history management method for managing the opening history of a container in which a product is enclosed.

[0002]

2. Description of the Related Art With the recent increase in the degree of integration of semiconductor circuits, a method of controlling devices using a small number of semiconductor substrates has been widely used not only in factory production sites but also in consumer applications and even in the field of amusement machines. I have been.

[0003] Usually, these semiconductor substrates are mounted so as to be easily inspected and adjusted by an expert engineer. However, the semiconductor substrates for room entry / exit control and a control program of a game machine are provided by a third party having specialized knowledge. Malicious adjustments or modifications can cause significant damage to the installer.

To prevent this, there is a method in which the semiconductor substrate is sealed in a container that cannot be opened. However, this method has a problem that it is not possible to perform an inspection when necessary. In order to solve this problem, a method has been used in which a warning is issued when a container is opened, a control operation is stopped, and a history of opening the container is monitored.

For example, in the invention disclosed in Japanese Patent Application Laid-Open No. 09-140902, a sealing seal provided with a resonance circuit is adhered over a main body and a lid of a container to be prohibited from being opened, and the resonance circuit is tuned. The sealing status of the container is confirmed using a sensor that transmits an electric wave and detects an echo wave due to resonance of the resonance circuit.

In the invention disclosed in Japanese Patent Application Laid-Open No. 08-243240, a control program for controlling the progress of a game and a game control information recording means for storing and holding game result information generated as the game progresses Covering means for obscuring the cover, and between the game control information recording means and the covering means, when the fitted state between the game control information recording means and the covering means is broken, an opening signal is provided. A means for monitoring opening is provided.

[0007] In the invention disclosed in Japanese Patent Application Laid-Open No. 07-236734, a game control board for controlling the playing state of the gaming machine is housed in the board housing means, and the opening of the board housing means is monitored. Monitoring means for monitoring the destruction of the board, monitoring the movement of the substrate housing means from a predetermined position, or stopping the control operation function of the game control means if an abnormality is found, When a predetermined person opens the package for inspection or the like, a means is provided for allowing the package to be opened according to a predetermined procedure.

[0008]

As described above, eliminating improper acts on a printed circuit board housed in a case is difficult.
This is possible if the case itself is completely sealed, but it has a major problem in terms of maintenance.
In addition, the incorporation of complicated circuit elements for this countermeasure also poses a problem in terms of cost, and in such a situation, simple and effective defense measures against illegal activities must be considered.

In the invention disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 09-140902, it is necessary to provide a sensor connected to a host computer for each container in order to constantly monitor each device. Using frequency can reduce the number of sensors, but in any case, it is necessary to build a system using a host computer, and if employees go around using portable sensors, equipment costs will be reduced Although possible, there is a problem that the accuracy of discovery is reduced. In this case, if the sealing seal provided with the resonance circuit is adhered again, there is no history of opening.

In the invention disclosed in Japanese Patent Application Laid-Open No. 08-243240, an opening signal of an opening monitoring means for detecting a change in electric resistance attached to each device can be connected to a management system of a game arcade and monitored centrally. It is like
Although the equipment is relatively simple, the opening signal is turned off when the opened lid is returned, so that there is a risk that the unauthorized operation may be overlooked depending on the monitoring condition, and that there is no history of the opening.

In the invention disclosed in Japanese Patent Application Laid-Open No. H07-236734, a monitoring function is provided for monitoring the release of the connection state and the opening of the board container, respectively, on the game control board, the payout control board, and the display control board. When an abnormality is monitored, the control operation function of the board is stopped and the system is notified to the monitoring data general means.The system is complicated, and when it is closed again after opening, the abnormality is released and the There is a problem that history does not remain.

On the other hand, if the control board of the apparatus has a problem in the control board of the apparatus and the history of opening the container for storing the control board is unknown at the time of inspection or return, if the history is not known, the cause is to the supplier. There is a problem in that it is impossible to determine whether there is a modification due to opening during use, and the location of responsibility is unclear. It is desirable to be able to record the opening history.

An object of the present invention is to provide a product container opening history management means and management method which can monitor the opening of a product container and manage the opening history, with a simple configuration and a small electric load.

[0014]

The product container opening history management means of the present invention is a means for managing the opening history of a container for storing a product, wherein the container for storing the product is a second container for engaging the product. The first case includes a case and a first case that engages with the second case to form a container. A projection is formed inside the first case, and the second case includes a first case.
When the case and the second case are engaged for sealing, the projection formed inside the first case pushes down the push button, and is arranged in a state of incrementing the frequency information. When the push-type cord output switch is engaged with the first case and the second case for sealing, the protruding portion formed inside the first case blocks detection light.

The push-type code output switch includes a switch body, a push button, and a code output terminal. Each time the push button is pressed, the switch body outputs a code corresponding to the number of times to the code output terminal as frequency information. Output, the code is preferably set so that it cannot be decremented and reset.

Further, the push-type cord output switch and the pair of optical coupling elements may be formed as an integral part.

Further, the product for which the opening history is to be managed may be a game control board of a game device.

The method for managing the opening history of a product container according to the present invention is a method for managing the opening history of a container storing a product,
Setting the initial condition in the push-type code output switch of the product container opening history means and the microprocessor for managing the product opening history, in which the number information is incremented when the push button is depressed, and the decrement and reset are impossible. A product, a push-type code output switch, a pair of optical coupling elements for detecting a shield by blocking light rays, and outputting case information of 0 when there is an obstacle and 0 when there is no obstacle, and a microprocessor. Engaging the first case, which is disposed on the second case and having the protrusion for operating the push-type cord output switch and the optical coupling element, with the second case, to form a container;
When the number of times information and the case information are in a predetermined combination, it is determined to be normal, and when the combination is different from the predetermined combination, a predetermined control is performed on the product as an open history, and an abnormal signal is output, Determining the opening history of the case from the frequency information recorded in the output switch.

The initial condition set in the push-type code output switch is 0, and a predetermined combination of the count information and the case information determined to be normal is a combination of the count information 0 and the case information 0 and the count information 1 And case information 1
The initial condition set in the push-type code output switch may be any integer, and a predetermined combination of the number information and the case information determined to be normal is that the number information is an arbitrary integer. A combination in which the case information is 0 and a combination in which the frequency information is an arbitrary integer + 1 and the case information is 1 may be used.

In the present invention, the management of the opening history of the case or the lid of the shipped product is managed by combining a push-type code output switch for detecting the number of times of opening and closing and an optical coupling element for detecting the presence or absence of an object by light. ,
The case opening and closing and the number of times the case is opened and closed can be managed. By setting the number-of-times information of the push-type code output switch so that it cannot be decremented or reset, intentional correction by a third party becomes impossible and security can be increased.

Both the push-type code output switch and the optical coupling element can be formed in a small size, so that they can be mounted on a printed circuit board, the product opening management means can be reduced in size, and power consumption is small.

[0022]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side sectional view of a product container opening history management means according to a first embodiment of the present invention, wherein (a) shows a state where the container is opened, and (b) shows a state where the container is closed.

In FIG. 1, a container for storing a product is composed of a second case 2 in which a printed circuit board 3 as a product is disposed, and a second case 2 in which a printed circuit board 3 is disposed.
And the first case 1 forming a container in combination with the above case. A projection 4 is formed inside the first case 1, and when the first case 1 and the second case 2 are engaged with the printed circuit board 3 for sealing,
To seal the push-type cord output switch 5 disposed in a state where the protrusion 4 formed inside the first case 1 pushes down the push button, and the first case 1 and the second case 2. A pair of optical coupling elements 6 and a printed circuit board 3 arranged so that the protruding portion 4 formed inside the first case 1 blocks a detection light beam when engaged with the first case 1; A microprocessor 7 for managing the opening history of the product based on information from the push-type code output switch 5 and the optical coupling element 6 is provided.

FIG. 2 is a schematic side view showing the structure of the push-type code output switch, and FIG. 3 is a schematic view of an output signal for explaining the operation of the push-type code output switch of FIG.

The push type code output switch 5 includes a switch body 51, a push button 52, and code output terminals 53,5.
4 and 55 and a common terminal 56. Switch body 51
Each time the push button 52 is pressed once, a code corresponding to the number of times is output to the code output terminals 53, 54, 55.
The output code is in a complement format, and the output terminal 53 is the least significant bit and the output terminal 55 is the most significant bit. Common terminal 56
Are output terminals 53, 5 inside the switch body 51.
4, 55 are connected or not connected.

The optical coupling element 6 outputs a signal of "1" when the detection light beam is cut off, and outputs a signal of "0" when the detection light beam is not cut off.

The code of the push type code output switch 5 is initially set to "0". Therefore, the microprocessor 7 first determines the combination of the case information “0” and the frequency information “0” when the first case 1 is not engaged with the second case 2 and the first case 1 first. Are determined to be normal only when the combination of the case information “1” and the number-of-times information “1” when engaged with the second case 2.

The operation of the push-type code output switch 5 will be described with reference to FIG. In the example of FIG. 3, since the output terminal has three bits, the management of the number of times of pressing is six times in total, not including the initial state. In FIG. 3, ○ indicates a state not connected to the common terminal 6, and ● indicates a state connected to the common terminal 6. In addition, this switch cannot be set to the initial state after the number of times it is pressed is six, that is, after the output code is incremented to seven,
In addition, the structure cannot be decremented even in the middle.

FIG. 4 is a schematic block diagram of the product container opening history management means of the present invention shown in FIG. When the first case 1 physically presses the push button 52 with the projection 4 provided on the case, the push-type code output switch 5 is mechanically determined by how many times the projection 4 of the first case 1 has been pressed in the past. At the same time that the number of times information is output, the detection light between the pair of optical coupling elements 6 is blocked by the projections 4 provided on the case. Output from

Based on the count information from the push-type code output switch 5 and the case information from the optical coupling element 6, the microprocessor 7 counts the count information "0" when the first case 1 has never been attached and Only when the case information is "0" and when the first case 1 is first attached is the frequency information "1" and when the case information is "1", it is determined to be normal, and the original control operation is performed. If the number-of-times information and the case information are conditions other than this combination, the operation of the product is stopped if necessary, and an abnormality alarm is transmitted. That is, when the first case 1 is opened after the container is sealed, the case information becomes "0" and the number of times information becomes "1", and the combination is not a predetermined normal combination. Therefore, the microprocessor 7 stops the operation of the product and issues an abnormality alarm. send. Even if the first case 1 is returned and sealed again, the case information returns to “1”, but the number of times information becomes “2”, which is not a predetermined normal combination. Stop the operation of
Send an abnormal alarm.

In this case, even if the microprocessor 7 is normally operated by some operation, the history of how many times the first case 1 has been opened and closed can be found by checking the frequency information.

Next, the method of managing the opening history of a product container according to the first embodiment of the present invention will be described in detail with respect to an inspection process and a monitoring state after the product is attached. FIG. 5 shows the first embodiment of the present invention.
FIG. 6 is a flowchart of an inspection step before use of the product container opening history management method of the embodiment, and FIG. 6 is a flowchart of an in-use and opening history management step.

Referring to FIG. 5, when an inspection before use is started (S101), an inspection in a state of being mounted on a printed board is first performed (S102). Examine the case information (S10
3) If the case information is not “0” (S103N),
It is determined that the optical coupling element is abnormal (S104), and the inspection ends (S114). If the case information is “0” (S103
Y), the frequency information is checked (S105), and the frequency information is "0".
If not (S105N), it is determined that the switch is initially abnormal (S106), and the inspection ends (S114). If the count information is “0” (Y in S105), it is determined that it is normal when mounted on the printed circuit board, and the inspection proceeds to the state in which the case is sealed (S107).

That is, in the state of the unit inspection in which the printed circuit board is not assembled in the case, the specification is determined as a condition for judging that the case information is “0” without the case and the switch has the initial value “0”. Have been.

The first case is attached to the printed circuit board attached to the second case (S108), and the case information is checked (S109). If the case information is not "1" (S109N), it is determined that the optical coupling element is abnormal. Determine (S11
0), the inspection ends (S114). If the case information is “1” (S109Y), the number of times information is checked (S1).
11), if the count information is not "1" (S111N),
It is determined that the switch operation is defective (S112), and the inspection ends (S114). If the number-of-times information is "1" (S
111Y), it is determined that the product container opening history management means operates normally even in the state of being stored in the case (S113), and the inspection ends (S114). Products will be shipped.

That is, when the microprocessor on the printed circuit board is housed in the case, the case information is "1" when there is a case, and the frequency information is 1 from the initial value "0".
This is a condition for determining a normal state in the state of the value “1” incremented only by “1”.

The operation of the product during use and in the opening history management process will be described with reference to FIG. When the operation is started with the product container opening history management means stored in the case determined to be normal attached to the apparatus (S201), the product container opening history management is started (S202), and the case information is checked (S201). S203), if the case information is not “1” (S203N), it is determined that there is an opening history (S205),
It moves to step S206. If the case information is "1" (S203Y), the count information is checked (S204). If the count information is not "1" (S204N), it is determined that there is an opening history (S205), and the process proceeds to step S206.

In step S206, the microprocessor stops the predetermined operation of the apparatus (S206), sends an abnormal signal (S207), and if the use is continued (S208).
Y), returning to step S206 and repeating the operation. If the use is not continued (S208N), the management operation ends (S212).

If the number information is "1" (S204)
Y), it is determined that there is no opening history, and if use is continued (S20)
9Y), returning to step S203 to repeat the operation. If the usage is not continued (S209N) and the history check is not necessary (S210N), the management operation ends (S21).
2) If it is necessary to check the history (S210Y), the number information is checked (S211), and the management operation ends (S212).

In other words, in order for the microprocessor to operate normally, the microprocessor must have the case information “0” and the count information “0”, or the case information “1” and the count information “1”. Is a program that can not operate unless either of the two conditions can be cleared, so if the case of the shipped product is opened in some way and then the case that is closed again is operated, the micro The processor operates only under the two conditions that the count information is “0” and the case information “0”, or the count information is “1” and the case information “1”. Cannot be operated because it is incremented to "2" by opening and re-closing. In addition, since the switch used here has a structure in which the depressed information cannot be decremented or reset, a third party cannot control or change the frequency information.

Since the push type code output switch increments the frequency information every time the push button is pressed, the history of the number of times of opening and closing of the case can be known by checking the frequency information of the push type code output switch. It is easy to determine whether the cause is due to the opening of the container or another cause.

Next, a second embodiment of the present invention will be described. In the first embodiment described above, the microprocessor operates only when the count information is “0” and the case information is “0”, or only when the count information is “1” and the case information is “1”. In the second embodiment, the condition for not operating the microprocessor is provided with an initial condition storage unit for information on the number of times that only the product provider can change the setting condition. Is “initial condition” and case information “0”, or the number of times information is “initial condition + 1” and case information “1”.
It is a condition that operates only under the two conditions.

In the first embodiment, the push-type cord output switch once opened had to be replaced.
Since the opening history is usually found only once,
According to the embodiment, the push-type cord output switch, which has been opened once, can be reused, thereby reducing costs. However, if the setting of the initial condition of the frequency information cannot be changed at the place of use, unless a microprocessor structure is used, a third party with technical knowledge may misuse the microprocessor.

Next, a third embodiment of the present invention will be described. In the second embodiment described above, the number of bits of the push-type code output switch is 3 bits, and the condition of the operation of the microprocessor is that the number of times information is “initial condition” and the case information is “0” Although the condition is such that the information operates only under the two conditions of "initial condition + 1" and case information "1", in the third embodiment, the number of bits is 4 bits or more.

Thus, in the second embodiment, the number of initial conditions that can be selected from 0 to 6 when the minimum incrementable number is 1 is set to 0 to 14 if the number is 4 bits. If it is 5 bits, there are 0 to 30 options. By setting the initial conditions arbitrarily in this range, the third party with technical knowledge can control or change the count information by replacing the push type code output switch, for example. The probability of doing this decreases.

Next, a fourth embodiment of the present invention will be described. FIG. 7 is a schematic perspective view of an opening history management switch according to the fourth embodiment of the present invention. In the first embodiment described above, an independent push-type code output switch and an optical coupling element are used. However, in the fourth embodiment, the push-type code output switch and the optical coupling element are formed integrally. The opening history management switch 70.

As a result, the degree of freedom in specifications such as the position of the push-type cord output switch and the object detection position of the optical coupling element is increased, and the work of attachment and detachment is facilitated.

Next, a fifth embodiment of the present invention will be described. The fifth embodiment is different from the previous embodiments in the circuit correspondence and the printed circuit board when information from the push-type code output switch and the optical coupling element is input to the microprocessor. . In the embodiments described above, information from the push-type code output switch and the optical coupling element is input to the microprocessor by wiring usually used for a printed circuit board.
In the embodiment of the present invention, in order to prevent the third party with technical knowledge from controlling or changing the case information and the count information through the wiring, it is difficult to connect or modify the line by a third party. I have.

For example, in a circuit for inputting information from a push-type code output switch and an optical coupling element to a microprocessor, a signal line is replaced with a normal wiring, a buffer is inserted, or a printed circuit board structure is used. For example, a blind through-hole structure is used in which the pattern is not visible on the printed circuit board surface because it is directly connected from the inner layer to the component mounting pads.

This makes it possible to further add a complicated element in terms of hardware, and further reduces the probability that a third party having technical knowledge will control or change the frequency information.

In the above description, the product opening history management has been described for a general device. However, the product opening history management means and management method of the present invention are based on the game control of a game device such as a pachinko game machine or a coin game machine. It can be effectively used for monitoring the opening of a substrate.

FIG. 8 is a schematic block diagram of a game device incorporating the product opening history management means of the present invention. The play means 110 of the play apparatus 100 is the first case 10
Game control board 10 housed in first and second cases 102
3 is controlled by the play means control unit 109 above.

The first case 101 has a projection 1 inside.
04 is formed on the game control board 103.
When the first case 101 and the second case 102 are engaged for sealing, the projection 104 formed inside the first case 101 is arranged so as to depress the push button, and decrement and reset are performed. Formed inside the first case 101 when the first case 101 and the second case 102 are engaged for sealing with the push-type cord output switch 105 designed to be impossible. A pair of optical coupling elements 106 arranged so that the protruding portion 104 blocks the detection light beam, a function stopping means 108 having a function of stopping the function of the play means control section 109, and an alarm device 112 are operated. Opening monitoring means for controlling the alarm means 111 and managing the opening history of the product based on information from the push-type code output switch 105 and the optical coupling element 106. 07 and are disposed.

Normally, the push type code output switch 10
5 outputs a signal of "1", and the optical coupling element 106 outputs a signal of "1" indicating that the detection light beam is blocked. Under this condition, the opening monitoring means 107 determines that the signal is normal.
The play means control unit 109 controls the play means 110 in a normal mode.

From the second case 102 to the first case 10
1 is opened, the push-type cord output switch 10
The signal of "1" from 5 remains unchanged,
6 outputs a signal of “0” indicating the passage of light, the opening monitoring unit 107 determines that opening has been performed, and the function stopping unit 10
The control unit 109 stops the control function of the play means control unit 109 via the control unit 8 and outputs an alarm signal to the alarm unit 112 and the outside via the alarm unit 111.

Again, the first case 101 is the second case 1
When it is attached to 02, the optical coupling element 106 outputs a signal of “1” indicating light blocking, but the push-type code output switch 105 outputs an incremented signal of “2”, and the opening monitoring is performed. The means 107 determines that there is an opening, and stops the control function of the play means control unit 109 via the function stopping means 108 and continues outputting the alarm signal.

The third party can play the game means control unit 1 by some method.
Even if the control function 09 is restored, the incremented signal of the push-type code output switch 105 remains, and the opening history can be managed.

[0058]

As described above, the first effect of the present invention is that the opening of the case of the product after shipment is reliably detected and the opening history is managed, so that a third party can open the case. That is, it is not easy to make unauthorized modifications.

The reason for this is that the opening history can be managed based on a change in the number of times of pressing that occurs when the case is closed again, and that normal operation cannot be performed unless the case is closed. Because it is. Also,
The switch used in the present invention is designed so that depressed information cannot be decremented and reset, so that it is not possible to perform improper operation due to processing of the switch. Further, by making the code of the push-type code output switch multi-bit and setting the initial condition of the count information arbitrarily, it is possible to prevent a third party from improperly replacing the switch.

The second effect is that the device can be downsized and the power consumption is small. The reason is that a small switch that can be mounted on a printed circuit board is used, and the increment of the count information is performed by a mechanical operation. By integrating the push-type cord output switch and the optical coupling element, the size can be further reduced, and the mounting becomes easy.
