Abstract

PROBLEM TO BE SOLVED: To prevent a conductive member for a mark as a part where a reference position is detected from having an influence on an electrically conductive pattern on a circuit board due to an intentional illegal alterration. SOLUTION: A mark 128 on a circuit board 102 is continuously formed on a part of an electrically conductive pattern 130. That is, although the mark 128 is formed of an electrically conductive member, the conductive member is not independent but it forms a part of the electrically conductive pattern 130 contributing to the electric conductivity of the electronic parts. That is, a function as a mark 128 can be applied to the pattern 130. Since a position on the circuit of the conductive member forming the mark is univocally decided, the device has a structure that a illegal alteration such as changing of the circuit or the like can not be committed by using the electrically conductive member.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine substrate provided in a game machine requiring electronic control and in which conductive patterns of electronic components to be mounted are formed in advance, and a method for eliminating a reference position detected portion of the game machine substrate.

[0002]

2. Description of the Related Art In recent years, game machines such as pachinko machines have been equipped with electronic control devices. The electronic control device generally mounts each electronic component based on a conductive pattern printed on a substrate in advance.

[0003] The substrate is initially provided with a conductive layer of copper or the like on the entire surface, and only a necessary portion is protected by a photo-printed conductive pattern film, and a chemical treatment such as etching is performed. As a result, a desired wiring is obtained by removing an unprotected portion. Further, after that, a through hole for inserting a terminal of the electronic component is provided, the electronic component is inserted into the through hole, and is fixed from the back side by soldering or the like, thereby completing a main part of the electronic control device.

The positioning and mounting of electronic components on a substrate are performed by an automatic machine. In order to position and mount the electronic component on the substrate by an automatic machine, a reference position is required.

Therefore, when forming the conductive pattern, a mark is formed as a reference position detection part at least at two positions (diagonal positions are optimal) near the peripheral edge of the substrate (preferably near the four corners). ing.

[0006] The mark is called a "fiducial mark" or a "master mark", and its position is recognized by being detected by a camera installed on the automatic machine side.

As an example of the control of the automatic machine, a board recognition camera and a component recognition camera are provided, and the posture at the time of holding (sucking) the mark and the electronic component is recognized, and each of them is set at a predetermined position. The electronic component is moved to a predetermined position on the substrate. Since the camera only needs to be able to recognize the mark and the outline silhouette of the electronic component, binarizing the read image data (white and black images) allows a large amount of time to be taken for image processing. There is nothing.

[0008] The mark is generally provided as an independent pattern that does not conduct with other conductive patterns.
As shown in FIGS. 9A to 9D, there are a mark 150 having a square band of a conductive member having a predetermined width, a mark 152 having a regular triangle, a mark 154 having a circle, and a mark 156 having a rhombus. Each mark 150, 152, 154, 15
6, the outer dimension A is 1-2 mm ± 5%, and the width B of the conductive member band is 0.03-0.2 mm.

[0009] As another type of mark shape, as shown in FIGS. 9 (E) to 9 (G), marks 158, 160, which are formed of square, regular triangle, and circle only by conductive members, are shown.
162 are applied, and each mark 158, 160, 1
The outer dimension C of the cylinder 62 is specified to be 0.5 to 1 mm. Note that the marks are collectively referred to as marks 164.

If a mark 164 having a predetermined shape is selected from the above (preferably one type), and the conductive pattern is provided on the substrate, the mark 164 is expressed on the substrate. Positioning and mounting work becomes possible.

[0011]

However, the mark 164 is formed of a conductive member and is isolated from the conductive patterns of other electronic components. That is,
This means that unnecessary conductive portions remain in the circuit on the substrate.

For this reason, it cannot be said that there is no possibility of intentionally using the conductivity of the mark 164 to change the conductive pattern to change the function of the electronic control device itself. In particular, in the pachinko machine industry, there is a risk that doubts may be raised during inspection if the pachinko machine may be used for unauthorized modification of the functions of the pachinko machine.

By providing the mark 164, it is necessary to provide a space corresponding to the mark 164, and the size of the substrate is correspondingly increased. The board of the electronic control device is a main part, and if the board is large, the entire electronic control device becomes large.

In view of the above facts, the present invention provides a substrate for a game machine and a game machine capable of preventing a conductive member of a mark from affecting a conductive pattern on the substrate by intentional tampering. It is an object of the present invention to provide a method for eliminating a reference position detected portion of a mechanical substrate.

And

According to the first aspect of the present invention, if the reference position detection portion has a function as a reference position when electronic components are mounted, it is unnecessary when the electronic component is finally mounted on a game machine. Therefore, if an independent conductive member is not left after the work requiring the function as a reference is completed, it will not be used for intentional unauthorized remodeling.

The reference position detection part used for detecting the reference position required at the time of mounting is a non-conductive part formed by being surrounded by the conductive member of the conductive pattern.

According to the third aspect of the present invention, if the reference position detected portion is a non-conductive portion surrounded by a conductive pattern, the reference position detected portion is used for unauthorized modification of wiring. There is no problem at all.

According to a fourth aspect of the present invention, in the third aspect of the present invention, the non-conductive portion is a through-hole penetrating the front and back surfaces of the substrate.

A reference position detection portion used for detecting a reference position obtained at the time of mounting is provided outside a region finally used as a substrate.

According to a fifth aspect of the present invention, a plurality of conductive patterns are formed on one large substrate, instead of being disposed on an automatic machine for positioning and mounting electronic components one by one. Then, the electronic component may be cut after positioning and mounting.

In this case, since the cut portion has a cut allowance (gap allowance), if the reference position detection portion is provided in this cut allowance, the reference substrate is provided on the final substrate after cutting. No detector is left. For this reason, the substrate can be reduced in size, and cannot be used for unauthorized modification.

According to a sixth aspect of the present invention, there is provided a game machine board provided with a game machine requiring electronic control, wherein a conductive pattern is formed in advance, wherein the electronic component mounted on the game machine board is provided.

According to the sixth aspect of the present invention, it is possible to secure the precision required for positioning components used in amusement machines, based on recent silk printing techniques. Therefore, by printing the reference position detection portion during silk printing, which prints a logo mark or the like on the substrate after the formation of the conductive pattern, the reference position detection portion can be formed with the non-conductive member, and the tampering is performed. It cannot be used for

According to a seventh aspect of the present invention, there is provided a game machine board provided with a game machine requiring electronic control, wherein a conductive pattern is formed in advance, wherein the electronic component mounted on the game machine board is provided. A reference position detection part used for detecting a reference position obtained at the time of mounting is formed by the outer shape of the substrate.

According to the seventh aspect of the present invention, if the external shape of the substrate is used as a reference, it is not necessary to provide a reference position detection portion forming region on the substrate, and the substrate can be downsized. As a result, the size of the electronic control device itself can be reduced, and it cannot be used for unauthorized modification.

The unit substrate 106 is a single unit.

The table 104 comprises a main table 110 on which the substrate 102 is placed, and a moving table 112 for supporting the main table 110. The main table 110 is provided with a reference line (not shown) for positioning and mounting the substrate at a certain position in advance.

Here, a male screw 124 is formed on one shaft 120 and is screwed to the leg 118. A rotating shaft of a motor is connected to one end of the shaft 120 as a Y-direction moving mechanism (not shown), and the moving table 112 is moved in the Y direction by rotating the shaft 120 with the driving force of the motor.

The positional relationship of the camera 126 coincides with the positional relationship of the mark 128 provided as a reference position detection unit provided for each unit substrate 106. Therefore, by detecting the pair of marks 128 simultaneously by the pair of cameras 126, it can be recognized that the conductive pattern 130 (see FIG. 2) formed on the unit substrate 106 is positioned at a regular position. .

The moving table 112 is supported by a turntable 132. The rotation axis of the turntable 132 is aligned with the axis of one camera 126 (the camera 126A located inside the main table 110). The turntable 132 is rotated by the driving force of a drive unit (not shown), and can rotate the main table 110 and the moving table 112 in the θ direction (the arrow θ direction in FIG. 1) about the axis of the camera 126A.

That is, the main table 110 stores XY-
The position correction is performed so that the pair of cameras 126 and 126A detect the pair of marks 128 based on the detection results of the cameras 126 and 126A.

When the position of the substrate 102 is determined, the electronic component is held by a component suction arm (not shown), the posture is corrected by an electronic component camera, and the electronic component is moved to a predetermined position on the substrate 102 and mounted. It is supposed to.

As described above, by detecting the mark 128 provided on the substrate 102 by the cameras 126 and 126A, the substrate 102 can be positioned at the reference position, and the electronic components can be mounted automatically.

As shown in FIG. 2, the mark 128 on the substrate 102 is provided continuously to a part of the conductive pattern 130. That is, although the mark 128 is formed by a conductive member, the conductive member is not independent and forms a part of the conductive pattern 130 that contributes to wiring of the electronic component.

That is, since the position of the conductive member serving as the mark 128 on the circuit is uniquely determined, the structure cannot be used to illegally modify the circuit using the conductive member. .

The operation of the present embodiment will be described below. Substrate 10
2 is subjected to an etching process based on the film on which the conductive pattern is printed to form a conductive pattern 130. At this time, the mark 128 is formed in a state where it is electrically connected to a part of the conductive pattern 130.

After the substrate 102 is placed at a predetermined position on the main table 110, the marks 128 are detected by the cameras 126 and 126A. In this case, since the reference position is provided on the main table 110 and the positioning is performed to some extent, the mark 128 exists near the photographing position of the cameras 126 and 126A.

Here, based on image signals (binarized data) photographed by the cameras 126 and 126A, a mark 128
The main table 110 is moved in the XY-θ directions to correct the posture of the main table 110. If they completely match, a pair of cameras 12

In this case, since the position of the substrate 102 and the position of the electronic component are respectively predetermined reference positions, the electronic component can be reliably moved to the designated coordinate position.
It can be mounted according to the mounting pattern provided on the conductive pattern 130 of the substrate.

When the mounting of all the electronic components is completed (including the soldering), the board 102 is removed from the main table 110 and cut on the basis of the cut margin 108 to form the unit board 106, and each electronic control device To be mounted on.

Here, conventionally, a conductive member independent of the conductive pattern 130 has been used as the mark 164. Therefore, it is expected that the mark 164 will be used to illegally remodel the wiring. In the amusement machine industry, questions were raised during the inspection. However, in the present embodiment, since the conductive member forming the mark 128 is electrically connected to and electrically connected to a part of the general conductive pattern 130 used and used, the conductive pattern 130 is Can be diverted as Further, since the position on the circuit formed by the conductive pattern 130 is uniquely determined, unauthorized modification using the mark 128 cannot be performed, and there is no suspicion at the time of inspection.

As described above, in the present embodiment, the mark 1
When forming 28, in cooperation with the conductive pattern 130,
Since it is formed on the substrate 102 in a state where it is electrically conducted as a part of the conductive pattern 130, it does not lose its original function as the mark 128 and does not remain as an independent conduction member. There are no problems that cause unnecessary doubt.

In this embodiment, a pair of marks 128 are provided on the diagonal line of the unit substrate 106, but three or more marks 128 may be provided. Further, the position is not limited to the diagonal line but may be the center of the substrate. Further, if the shape of the mark 128 is different from that of the keyhole, for example, by 360 °,
Only one mark 128 is required.

Although the shape of the mark 128 is a square, it is not limited to a triangle, a circle, a rhombus or the like as shown in the prior art.

In the present embodiment, the table 104
Can be moved (rotated) in the XY-θ directions,
6, the substrate 102 is positioned at the regular position based on the information photographed at 126A. However, the amount of deviation from the regular position is recognized by coordinates or the like, and the predetermined position coordinates of the electronic component are determined. May be corrected. In this case, there is no need to provide the table 104 with a moving mechanism.
It is possible to process only by operation. (First Modification) The mark 12 according to the present embodiment will be described below.
8 shows a first modified example. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description of the configuration will be omitted.

As shown in FIG. 3, in a first modification, a portion to be applied as a mark 134 is
A value of 0 indicates a non-conductive member surrounded by the conductive member.

As a result, the mark 134 cannot be used for unauthorized modification. (Second Modification) The mark 12 according to the present embodiment will be described below.

As shown in FIG. 4A, in the second modification, a portion applied as the mark 136 is a portion surrounded by a conductive member as the conductive pattern 130, and a through hole 138 is formed in this portion. (See FIG. 4B). Thereby, the cameras 126, 126 shown in the above-described embodiment are provided.
Not only the method A, but also a relatively inexpensive sensor such as a transmission type density sensor in which the light projecting unit and the light receiving unit are independent can be applied. Also, the mark 136 is not used for unauthorized modification. (Third Modification) The mark 12 according to the present embodiment will be described below.
8 shows a third modified example. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description of the configuration will be omitted.

As shown in FIG. 5, in the third modification, a mark 140 is provided on the cut margin 108 existing as the substrate 102 without providing a mark for each unit substrate 106. Therefore, at the time when the unit substrate 106 is formed, the mark 140 does not exist on the unit substrate 106, so that there is no suspicion caused by a single conductive portion, and the mark 140 is not used for unauthorized modification.

The board 10 finally mounted on the game machine
Since there is no need to prepare an area for providing the mark 140 in the substrate 2, the size of the substrate itself can be reduced accordingly. (Fourth Modification) The mark 12 according to the present embodiment will be described below.

That is, in the above, as shown in FIG. 2, since the mark 128 was formed at the same time as the conductive pattern 130 formed on the substrate 102, there was an independent conductive portion, which caused doubt. Therefore, the mark 142 is printed at the time of silk printing, which is another process completely unrelated to the conductive pattern 130. With the recent silk printing technology, it is possible to ensure the precision required for positioning components used in amusement machines. For this reason, after forming the conductive pattern, by printing the mark 142 at the time of silk printing for printing a logo mark or the like on the substrate, the mark 142 can be formed with a non-conductive member, and it is not used for unauthorized modification. impossible. (Fifth Modification) The mark 12 according to the present embodiment will be described below.
8 shows a fifth modification example. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description of the configuration will be omitted.

As shown in FIG. 7, in the fifth modification, a notch having a characteristic shape is provided in each outer portion of the substrate 102, and the cutout is applied as the mark 144. In this case, since it is not necessary to prepare a region for providing the mark 144 on the substrate 102, the size of the substrate itself can be reduced. Since the board 102 forms a main part of the electronic control device, the size of the electronic control device itself can be reduced as a result. Also, it is not used for unauthorized modification. (Sixth Modification) The mark 12 according to the present embodiment will be described below.
8 shows a sixth modification of the eighth embodiment. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description of the configuration will be omitted.

As shown in FIG. 8A, the fifth modified example follows the formation of a conventional mark 146. However, the mark 146 and its surroundings are cut by an additional process to provide a through hole 148 (FIG. 8).
(B)). Thus, when mounted on an electronic control device, there is no doubt since the mark 146 itself does not exist.
