Description

  The present invention relates to a human body contact detection device, and in particular, stably realizes a human body contact detection operation, suppresses a decrease in human body contact detection accuracy (suppresses variation), and destroys the device due to static electricity. More particularly, the present invention relates to a human body contact detection device which can be prevented and can be easily attached.

  Many switches are used in pachinko gaming machines for the purpose of detecting a game ball, detecting a human body (player), or detecting the position of a structural member. In this case, in the case of the operation trigger switch that starts the operation of the pachinko gaming machine, if a contact switch is used, a unique chattering occurs when opening and closing, so use a small electronic switch instead of a contact switch Has become the mainstream. As such an operation trigger switch, in addition to a proximity switch that detects the passage of a game ball, recently, based on the capacitance that changes when a player touches a handle that operates a game ball launcher, the human body Capacitance-type human body detection touch switches that detect the contact of the human body are being introduced.

  A human body detection touch switch determines whether or not a human body has come into contact based on the change in capacitance between the plates when a human body (directly or indirectly) comes in contact with a metal plate provided in advance. The determination result is output as a signal.

  Furthermore, for the launching device of the pachinko gaming machine, it is stipulated that the player has a function of stopping the launch of the game ball with the player's intention while holding the handle. A stop switch is used.

  Therefore, the handle body has a built-in stop switch as a function to stop the launch of the game ball at the player's intention while holding the handle and the human body detection touch switch, and the power supply state of the human body detection touch switch can be changed by turning on / off the micro switch. There is one that simplifies the processing of the operation of the human body detection touch switch and the stop switch by switching (for example, see Patent Documents 1 and 2).

  Further, when such a human body detection touch switch is introduced into the pachinko gaming machine, it is necessary to take measures against static electricity.

  That is, electrostatic discharge to the touch switch occurs when a player (human body) charged with static electricity in winter or the like touches or approaches the touch switch. The electrostatic discharge voltage at this time reaches tens of thousands of volts when, for example, a human body wearing a woolen fabric walks on a carpet. In general, the electrostatic resistance of an electronic switch is significantly lower than that of a contact switch, and when an overvoltage due to static electricity as described above is discharged to the touch switch, the internal electronic components may be electrostatically damaged. Therefore, such a human body detection touch switch circuit needs to coexist with a configuration for performing an electrostatic protection operation in addition to a configuration for detecting whether or not a human body has touched.

  Regarding countermeasures against static electricity in small electronic switches, when a human body comes in contact with a detection electrode that detects contact with the human body, even if static electricity charged at the same time enters the circuit, the discharge route leads directly to the circuit ground via the protective element. In some cases, the static electricity is immediately discharged to the outside of the touch switch through the circuit ground to suppress the influence on the part having low electrostatic resistance such as the oscillation circuit (for example, see Patent Document 3).

  In addition, instead of the discharge route to the circuit ground, there is one in which the discharge is made to the frame ground which is a grounding portion that is more stable than the circuit ground (see, for example, Patent Document 2).

  Here, a touch switch including the above-described stop switch will be described with reference to FIG.

  The touch switch 1 is provided in a handle main body base B of an operation handle that is operated to fire a game ball of a pachinko gaming machine. The detection circuit 15 of the touch switch 1 is disposed on the circuit board 16 and is driven by electric power supplied from the control board 5 that controls various functions such as launching a game ball. When the touch antenna 11 detects contact with a human body, A contact detection signal is supplied to the control board 5 via the connector 13 and the electrical path 4. More specifically, the terminal 13a of the connector 13 is composed of a power supply line, a signal line for transmitting a detection result, and a ground line, and the detection circuit 15 is driven by the power supplied from the connector 13 for detection. The result is output to the control board 5 via the connector 13.

  When the control board 5 is supplied with a signal indicating that the human body is in contact based on the detection result supplied from the touch switch 1, the control board 5 drives the motor M6 to display the game ball. Launched in a pachinko machine not shown.

  Between the detection circuit 15 and the connector 13, a connector 14, a connection line 12a, and a stop switch 12 are provided. The stop switch 12 is turned off when the player wants to stop firing the game ball, and is turned on at other times. The stop switch 12 directly outputs the output result from the detection path 15 to the connector 13 when in the on state, but the contact detection signal is forcibly cut off when the stop switch 12 is off. As a result, when the stop switch 12 is turned off, the human body contact detection signal is not always supplied from the detection circuit 15 to the control board 5 regardless of whether or not the human body is in contact with the touch antenna 11. It becomes a state. For this reason, since the motor M6 is not driven, the launch of the game ball is forcibly stopped.

  The touch antenna 11 is grounded via the arrester substrate 3 provided with the arrester 3 a via the wiring 2.

  As shown in FIG. 1, by providing the stop switch 12 as a means for stopping the launch of the game ball in the power supply path of the detection circuit 15, by switching the power supply state to the detection circuit 15 by opening and closing the stop switch 12, The launch control of pachinko machine game balls has been simplified. However, when the power supply state to the detection circuit 15 is switched, since the circuit operation of the detection circuit 15 is not guaranteed for a certain period of time until the power supply to the detection circuit 15 is distributed, a malfunction pulse is generated when the control circuit 5 turns on the power. There is a problem that it occurs or the output start timing of the regular signal is delayed.

  Further, when the power supply state is switched by using a contact switch as the stop switch 12, chattering may occur in the power supply to the detection circuit 15 or the output signal from the detection circuit 15, and as a result, in the subsequent stage It was necessary to provide a configuration to prevent chattering.

  Further, the detection circuit 15 used in the pachinko game machine is generally a high-frequency oscillation type touch switch. For example, in the case of the DC 2-wire touch switch 1 (see Patent Document 2), the stop switch 12 It is difficult to discriminate in the control circuit 5 in the subsequent stage when the power supply state to the detection circuit 15 is stopped by opening the state (OFF state) and when the touch switch 1 detects human contact. was there.

  That is, in the case of the high-frequency oscillation type touch switch 1 using the DC two-wire detection circuit 15, the detection circuit 15 is connected to the touch antenna 11 from the internal oscillation circuit (not shown) due to the addition of capacitance. The oscillation is stopped, and as a result, the operation is turned off. Further, when the human body is not in contact with the touch antenna 11, the detection circuit 15 is in a state where no capacitance is added, and a signal having a predetermined frequency is oscillated from an internal oscillation circuit (not shown), and as a result, the operation is turned on. It becomes the state of.

  At this time, even if the operation of the detection circuit 15 is in an OFF state, a constant consumption current flows in order to keep the circuit operating (generally called a leakage current). There is a constant internal constant voltage (generally called a residual voltage) in order to maintain the circuit operation even when is turned on.

  Since both the leakage current and the residual voltage of the DC 2-wire high frequency oscillation type touch switch 1 need to be minimized, the current consumption is minimized when the detection circuit 15 is in the off state (open state). Will be. As a result, the detection circuit 15 is set to an off state when detecting a human body contact in an oscillation stopped state with low current consumption.

  Although it is possible to configure the operation of the detection circuit 15 to stop when the detection circuit 15 is in an on state (closed state) at the time of detecting a human body contact, the leakage current is very large and the characteristics tend to vary. Therefore, it is expected that it is difficult to control the operation.

  Therefore, when the detection state of the touch switch 1 is that the detection circuit 15 at the time of human body contact detection is in the off state, even if the power supply state of the touch switch 1 is switched to the stop state, Since only the non-operational state due to the power supply stop to the switch 1 is brought about, it is very difficult to determine this difference. As a result, the function of the stop switch 12 for the purpose of a pachinko gaming machine is actually There was a problem that could not be realized.

  In FIG. 1, a stop switch 12 comprising an external contact switch is provided. However, the number of connecting parts as the touch switch 1 increases (connectors 13 and 14), and the touch switch 1 is actually enlarged. As a result, it is practically difficult to incorporate it in the handle body in a narrow space, and the man-hours and costs for production increase as the number of connectors increases.

  Furthermore, since the number of parts is not reduced as a result of an increase in the number of connections as the touch switch 1, there is a problem in that the main body of the handle, which is the main purpose, cannot be simplified.

  Further, when the stop switch 12 made of a contact switch is inserted at a position where the power supply line is directly opened / closed, various problems as described above are expected. Therefore, the small signal circuit inside the detection circuit 15 is opened / closed instead. Although a configuration is conceivable, when the stop switch 12 made of a contact switch is inserted into the detection circuit 15 made of a capacitive high-frequency oscillation circuit, the capacitance between the ground of the stop switch 12 itself made of the contact switch and the connection line 12a Since the stray capacitance related to the capacitance becomes a variation factor of the capacitance detection characteristic of the oscillation circuit (especially, the routing method of the connection line 12a, the influence of surrounding metal, and the degree of proximity to other wiring, etc. vary for each handle. There is a possibility that the variation of the operation of the touch switch 1 may be increased.

  Furthermore, when the touch switch as described above is mounted on a pachinko gaming machine, a new problem related to static electricity occurs.

  That is, with the configuration of the touch antenna 11 as shown in FIG. 1, for example, when a player who is charged with static electricity touches the metal part of the handle body base B, the detection circuit 15 reacts and the human body contact presence / absence signal is transmitted to the control board. The static electricity charged to the human body is discharged to the handle body base B at the same time.

  In such a case, for example, in the touch switch 1 of FIG. 1, the wiring 2 and the arrester substrate 3 are not connected from the touch antenna 11 and are configured to be discharged directly to the circuit ground as a countermeasure against static electricity. The aforementioned static electricity passes through the detection circuit 15, passes through the electric path 4, and reaches the control board 5. As a result, there is a risk of causing troubles in places other than the touch switch 1, such as occurrence of electrostatic breakdown of the control board 5. That is, when the static electricity is discharged to the circuit ground, the circuit protection of the touch switch 1 can be performed by static electricity, but there is a possibility of causing an adverse effect on other portions of the pachinko gaming machine.

  Therefore, as shown in FIG. 1, the touch switch 1 is protected by an arrester 3 a as a countermeasure against electrostatic breakdown of the control board 5. That is, one end of the arrester substrate 3 is connected to the metal portion of the touch antenna 11 of the handle body base B, and the other end of the arrester substrate 3 is grounded to the frame ground FG. The arrester board 3 itself is disposed on the pachinko gaming machine side in the handle body base B or through the wiring 2.

  Here, the grounding to the frame ground FG means a connection to a metal casing provided in a pachinko gaming machine called a frame ground (hereinafter also referred to as FG), an outer frame of the pachinko gaming machine, a board cover, Alternatively, the metal parts of the main body frame are connected together, and are grounds in which the potential is stably guaranteed while being electrically insulated from the internal circuit in order to prevent accidents such as electric leakage and electric shock.

  In other words, the circuit ground potential inside the pachinko machine is in a so-called floating state that is insulated from the ground and is never a stable ground potential, and its stability is determined by the capacitance between the grounds of the circuit ground. The On the other hand, the frame ground FG is the stable ground potential in the entire pachinko gaming machine, and it can be said that it is optimal as the final destination for discharging surges such as static electricity.

  Therefore, in the touch switch 1 mounted on the pachinko gaming machine, securing a discharge route to the frame ground FG leads to a more complete countermeasure against static electricity, rather than a circuit ground where stability is not guaranteed.

  That is, as a countermeasure against static electricity shown in FIG. 1, when the arrester 3a, the arrester substrate 3, and the wiring 2 are connected to the touch antenna 11 in a state of being grounded to the frame ground FG, the touch switch 1 and the pachinko gaming machine are prevented from electrostatic discharge. It becomes possible to protect stably. However, on the other hand, since the stray capacitance of the wiring 2 is added to the touch antenna 11, the detection accuracy of the human body contact by the touch switch 1 is reduced due to the difference in the arrangement method of the wiring 2 (variation varies). There was a problem that it would occur).

  In addition, wiring the touch switch 1 and the stop switch 12 separately increases the number of man-hours during manufacturing, which increases the number of parts. There has been a problem of increasing the amount.

  The present invention has been made in view of such a situation, and while making the contact detection operation of the human body stable, while suppressing a decrease in the detection accuracy of the human body contact (while suppressing variations), This makes it possible to prevent damage to the device due to static electricity, and to suppress an increase in the number of work steps and the number of parts involved in manufacturing.

  The human body contact detection device of the present invention electrically detects contact of a human body with a contact portion where the human body directly or indirectly contacts and when the contact portion is directly or indirectly contacted by the human body. Provided with a detection unit and an open / close switch that opens and closes the connection between the contact unit and the detection unit. When the open / close switch is in a closed state, the detection is performed when the contact unit is directly or indirectly contacted by a human body. The part electrically detects contact of the human body with the contact part, and the contact part and the open / close switch are integrated, and the surface constituting the contact part and the movable direction of the open / close switch are parallel to each other. It is characterized by.

  In the human body contact detection device, a conductive screw is inserted in a direction perpendicular to the movable direction of the open / close switch and in contact with the surface constituting the contact portion, and is screwed onto the mounting surface. Features.

  It is possible to further provide a connection part consisting of a wiring drawer that receives the power supply or outputs an output signal or a connector, and the connection part is configured in a direction perpendicular to the movable direction of the open / close switch. You can make it.

  In the pachinko gaming machine of the present invention, the human body contact detection device according to any one of claims 1 to 3 is built in the game handle, and a surface constituting the contact portion is arranged in parallel to the front of the main body. It is characterized by.

  In the human body contact detection device of the present invention, when the human body is directly or indirectly contacted by the contact portion and the contact portion is directly or indirectly contacted by the human body by the detection portion, the contact to the human body contact portion is electrically. When the contact part is directly or indirectly contacted by a human body when the connection between the contact part and the detection part is opened and closed by the open / close switch and the open / close switch is closed, the detection part Thus, the contact of the human body with the contact portion is electrically detected, and the contact portion and the open / close switch are integrated, and the surface constituting the contact portion and the movable direction of the open / close switch are parallel.

  The open / close switch can be, for example, a micro switch 161b made of a contact switch as shown in FIG. Since the micro switch 161b is provided in front of the detection circuit 191 (FIG. 11), even if chattering or the like occurs, the micro switch 161b is smoothed by the integration circuit 244 in the detection circuit 191 in FIG. It is possible to stably generate an oscillation signal having a predetermined frequency indicating that is non-contact.

  Since the contact portion and the open / close switch are integrated, for example, the surface constituting the contact portion such as the bottom surface portion 151 of FIG. 4 and the movable direction of the open / close switch such as the microswitch body 161 are parallel. Can operate the stop button 153 by using at least one of the fingers of the hand holding the handle body 112 while maintaining the state where the handle body 112 is held substantially. Therefore, the stop button 153 can be easily operated.

  Furthermore, when the touch switch 163 is attached to the handle unit 111, the resin molded member 150 is simply inserted into the resin molded member 150 by inserting metal screws 162a, 162b or 162 in the vertical direction and fixed by screwing. At the same time, it is electrically connected to the metal plate 173. In addition, the movable direction of the stop button 153 and the operation direction of the micro switch body 161a can be matched. Furthermore, when the metal screws 162a, 162b or 162 are screwed to the resin molding member 150, the connectors 181 and 182 are connected to each other. For this reason, the connection of the connectors 181 and 182 can be facilitated. In addition, since the touch switch 163 is integrally formed with the micro switch body 161, the micro switch body 161 can be fixed at the same time only by fixing the touch switch 163.

  As a result, the number of work steps for attaching the touch switch 163 to the handle unit 111 can be reduced, and the touch switch 163 and the micro switch body 161 can be integrated. By reducing the number of parts, the cost can be reduced.

  According to the present invention, it is possible to stably realize a contact detection operation of a human body and prevent a device from being destroyed by static electricity while suppressing a decrease in detection accuracy of a human body contact (while suppressing variation). In addition, the number of man-hours and the number of parts involved in the mounting operation can be suppressed, and the cost can be suppressed.

  2 and 3 are diagrams showing a configuration of a pachinko gaming machine 100 to which the present invention is applied.

  FIG. 2 is a front perspective view of the main body of the pachinko gaming machine 100, and FIG. 3 is a rear view of the pachinko gaming machine 100. FIG. 2 shows a state in which the glass door 105 of the pachinko gaming machine 100 is rotated with respect to an axis indicated by a dotted line in the figure and opened with respect to the main body.

  As shown in FIG. 2, the mechanism unit 101 of the launching device is provided in the main body of the pachinko gaming machine 100. The mechanism unit 101 includes a metal base plate 102. While the base plate 102 is fixed to the front frame 103 (or the base frame) of the pachinko gaming machine 100, the base plate 102 is attached with a firing motor, a firing cam, a hitting ball, and a spring for biasing the same. ing.

  The handle unit 111 is provided on the front surface of the main body of the pachinko gaming machine 100. The operation knob 113 of the handle main body 112 provided in the handle unit 111 rotates in the clockwise direction when viewed from the front of the main body of the pachinko gaming machine 100 in the figure, thereby operating a game ball launch control unit (not shown).

  That is, when the operation knob 113 is not operated by the player, the operation knob 113 is stopped at a limit angle that can be rotated counterclockwise as viewed from the front of the main body of the pachinko gaming machine 100 by a spring (not shown). Is done. When the player holds the operation knob 113 and rotates it clockwise in the figure, the handle unit 111 transmits a corresponding signal to a launcher (not shown) according to the rotation angle of the operation knob 113. . A launching device (not shown) is controlled by the control circuit 122, and based on a signal corresponding to the rotation angle of the operation knob 113 supplied from the handle unit 111, the launching motor and the launching cam are operated so as to hit the game ball. The strength of the game is controlled and a game ball is fired.

  The handle body 112 of the handle unit 111 has a built-in touch switch 163 (FIG. 4), and detects whether or not the player is holding the handle body 112 (the player touches the handle body 112). And the detection result is supplied to the control unit 122. For example, when it is determined that the player does not hold the handle body 112 based on the detection result, the control unit 122 controls the launching device to launch the game ball regardless of the rotation angle of the operation knob 113. Stop. On the other hand, when it is determined that the player is holding the handle main body 112, the control unit 122 controls the game ball to be fired according to the rotation angle of the operation knob 113. The handle body 112 has a surface plated with a conductor such as metal, and is electrically connected to metal plates 173a and 173b (FIG. 5) of a touch switch 163 (FIG. 4) described later. (FIG. 4) detects the presence or absence of contact of the human body based on the capacitance that changes when the human body contacts the handle body 112 via the metal plate 173.

  Further, as shown in FIG. 3, the pachinko gaming machine 100 is equipped with a power source 121 in the main body. The power supply 121 takes in AC power through the power terminal 131 and converts it into DC power. At this time, the voltage is adjusted to a plurality of stages (for example, three stages), for example. The plurality of supply voltages are set to, for example, low, medium, and high voltages (for example, 5V, 12V, and 34V), respectively.

  A prize ball control board 124 is connected to the power source 121. For example, when a game ball enters a winning opening in a game area (not shown), the prize ball control board 124 receives a prize ball command signal based on this and controls the payout operation of the prize ball. The game area is formed in the game board surface of the pachinko gaming machine 100.

  The control circuit 122 is connected to the prize ball control board 124. The control circuit 122 includes the main control circuit of the pachinko gaming machine 100. Here, for example, the operation control of the accessory, the hit determination, the probability setting, the winning detection, the jackpot control (opening / closing of the big winning opening), the effect instruction processing Various programs for performing the above are executed.

  The sub-control circuit 123 is connected under the control circuit 122, and executes a program for performing various controls such as output of sound effects and sounds accompanying the progress of the game, lighting decoration, and effects by video.

  The base plate 102 in FIG. 2 is connected to the lock device 104 (earth bond). When the glass door 105 is closed from the state shown in FIG. 2, the lock device 104 is engaged with the glass door reinforcing plate 106 on the inner surface. By being stopped, the glass door reinforcing plate 106 and the lock device 104 are electrically connected (earth bond). Further, the glass door reinforcing plate 106 is connected to the frame ground (FG) of the pachinko gaming machine 100.

  As shown in FIG. 3, the control circuit 122, the sub-control circuit 123, the power source 121, and the like described above are installed on the back of the pachinko gaming machine, and the power source 121 includes a power cord 131 and a ground wire 132. Is connected. The ground wire 132 combines frame grounds FG gathered from various places of the pachinko gaming machine 100 into one, and is connected to an earth device such as an island facility. As a result, the frame ground FG is a ground where a stable potential is secured unlike the circuit ground (the cold side of the DC power supply).

  Next, a detailed configuration of the handle unit 111 will be described with reference to FIG. FIG. 4 is an exploded perspective view showing a state in which the touch switch 163 is attached to the handle unit 111. The touch switch 163 is installed on the bottom surface portion 151 of the resin-molded member 150 plated with metal so that the metal plate 173 (FIG. 8) of the touch switch 163 is parallel to the bottom surface portion 151. 5, as shown in FIG. 6, screwed by metal screws 162a and 162b. 5 is a top view when the touch switch 163 is viewed from the front of the pachinko gaming machine 100, and FIG. 6 is a side view of the touch switch 163.

  As shown in FIG. 6, the metal screws 162a and 162b penetrate the holes 173a and 173b (FIG. 8) and the holes 171e and 171f (FIG. 8) of the metal plate 173 (FIG. 8), respectively, The handle body 112 and the metal plate 173 are electrically connected by being screwed and fixed to the molding member 150. Further, the connector (wiring lead-out portion) 181 of the touch switch 163 is connected to the connector 182 provided on the bottom surface portion 151 of the resin molding member 150.

  The touch switch 163 has a structure in which the micro switch body 161 is integrated. When the stop button 153 is pressed in the direction of the axis 152, the micro switch body 161 is brought into contact with the micro switch operating part 161a, and further, the micro switch operating part 161a is pressed in the direction of the axis 152, The switch 161b is pressed by the microswitch body 161, and in this state, the operation of the microswitch body is turned off. At this time, the touch switch 163 generates a signal for stopping the launch of the game ball.

  Further, the operation knob 113 is a resin molded member to which metal plating is applied, and rotates around the shaft 152 while maintaining contact with the resin molded member 150. As described above, the operation knob 113 of the handle main body 112 provided in the handle unit 111 rotates in the clockwise direction when viewed from the front of the main body of the pachinko gaming machine 100, thereby operating a game ball launch control unit (not shown).

  That is, when the operation knob 113 is not operated by the player, the operation knob 113 is stopped at a limit angle that can be rotated counterclockwise when viewed from the front of the main body of the pachinko gaming machine 100 in FIG. It is said. When the player holds the operation knob 113 and rotates it in the clockwise direction in FIG. 2, the handle unit 111 outputs a corresponding signal according to the rotation angle of the operation knob 113. To communicate. A launching device (not shown) is controlled by the control circuit 122, and based on a signal corresponding to the rotation angle of the operation knob 113 supplied from the handle unit 111, the launching motor and the launching cam are operated so as to hit the game ball. The strength of the game is controlled and a game ball is fired.

  At this time, when the stop button 153 is appropriately pressed in the direction of the axis 152, which is the direction of the arrow in the figure, the micro switch 161b is turned off and the launch of the game ball is stopped. The operation of stopping the launch of the game ball by pressing the stop button 153 in the direction of the arrow will be described later in detail.

  With the above configuration, when the touch switch 163 is installed in the handle main body 112 (the pachinko gaming machine may be installed outside the handle), the stop button 153 has the direction of the rotation shaft 152 ( It moves in the direction of the arrow in FIG. Therefore, the microswitch operation unit 161 a is arranged to be operated in parallel to the bottom surface part 151 of the resin molding member 150. More specifically, the surface of the metal plate 173 and the operation surface of the microswitch operation unit 161a are both parallel to the bottom surface unit 151. Further, the insertion direction of the metal screws 162 a and 162 b is set in a direction perpendicular to the bottom surface portion 151.

  As a result, the player can easily press the stop button 153 only by using at least one of the fingers of the hand holding the handle body 112 while maintaining the state of holding the handle body 112 substantially. Since it becomes possible to operate, the player stops the launch of the game ball as necessary while maintaining the rotation angle (the launch strength of the game ball) of the operation knob 113 for firing the game ball set by himself / herself. It becomes possible.

  Further, when the touch switch 163 is attached to the handle unit 111, the metal screws 162a and 162b are inserted into the resin molded member 150 in the vertical direction, and are screwed and fixed to the resin molded member 150. At the same time, the metal plate 173 is electrically connected. In addition, the movable direction of the stop button 153 and the operation direction of the micro switch operation unit 161a can be matched. Further, when the metal screws 162a and 162b are screwed to the resin molding member 150, the connectors 181 and 182 are urged to each other. For this reason, it is possible to connect the connectors 181 and 182 easily and reliably. As a result, the number of work steps can be reduced, and the micro switch body 161 and the touch switch 163 are integrated, so that the number of parts can be reduced and the cost can be reduced. Further, by reducing the number of parts, the apparatus can be reduced in size and simplified. The connector 182 is arranged in a direction perpendicular to the bottom surface portion 151.

  Next, the touch switch 163 will be described with reference to FIGS. Note that the touch switch 163 in FIGS. 7 and 8 is a diagram in which the front and back surfaces are reversed in the drawings. FIG. 7 is a perspective view showing the appearance of a touch switch (3-wire output 4 terminal: for power supply, circuit ground, signal output for human body contact detection result and frame ground FG terminal) 163. FIG. 8 is an exploded view of the touch switch 163.

  The detection circuit board 201 is housed inside the resin case 171a and the cover 171b, and the microswitch operation unit 161a and the metal plates 173a and 173b are exposed to the outside. The micro switch operation part 161a is projected at the upper part in FIG. 7, and the movable direction of the micro switch operation part 161a of the micro switch body 161 is parallel to the contact surface of the metal plates 173a and 173b. The microswitch operating unit 161a is movable in the direction of the arrow in FIG. 7, and is pressed downward from the upper surface of FIG. 7, thereby pressing the microswitch 161b downward from the upper surface of FIG. By this operation, the micro switch 161b is turned off. In other cases, the micro switch 161b is turned on by a repulsive force acting upward in the figure by a spring (not shown).

  Electronic circuits such as a connector 181 and a detection circuit 191 are connected to the upper surface portion of the detection circuit board 201 in FIG. 8 by a copper foil pattern. Further, the microswitch body 161 is inserted from the lower surface in FIG. 8, and the detection circuit board 201 is in a state where the convex terminals 161e to 161g of the microswitch body 161 penetrate the detection circuit board 201 and protrude to the upper surface side. It is electrically connected to the pattern of the copper foil on the upper surface portion in FIG. When the detection circuit board 201 is inserted after the metal plate 173 is arranged in the case 171a, the detection circuit board 201 and the metal plate 173 are brought into contact with a part of the back surface portion of the detection circuit board 201 in the drawing and the metal plate 173. Are in an electrically connected state.

  More specifically, the protrusions 171c and 171d of the case 171a pass through the holes 173c and 173d of the metal plate 173, respectively, and further pass through the holes 161c and 161d of the microswitch body 161, so that the microswitch body 161 urges the metal plate 173 toward the case 171a, whereby the detection circuit board 201 is inserted into the case 171a. As a result, the detection circuit board 201 and the metal plate 173 are electrically connected by the printed connection 221 (FIG. 10) on the back surface of the detection circuit board 201 of FIG.

  Further, as shown in FIG. 8, the cover 171b is press-fitted in the respective opposing directions in the drawing of the case 171a, so that the claws 171g provided at both ends of the cover 171b (provided at the end of the cover 171b). , 171h are engaged with the claws 171i and 171j of the case 171a, respectively, thereby being locked to the opening of the case 171a and protecting the detection circuit board 201.

  Next, a circuit pattern of the detection circuit board 201 will be described with reference to FIGS. 9 is a top view of the detection circuit board 201 of FIG. 8, and FIG. 10 is a rear view of the detection circuit board 201 of FIG. In FIG. 9 and FIG. 10, the range colored with a horizontal line or a vertical line in the figure indicates a circuit pattern made of copper foil.

  As shown in FIG. 9, a connector 181, a detection circuit 191, an input resistor 193, and a capacitor 192 are provided on the upper surface of the detection circuit board 201, and a metal plate 173 is provided on the back surface as shown in FIG. 10. The printed wiring 221 and the micro gaps 222 and 223 that are in contact with the substrate are formed in a copper foil pattern, and the micro switch body 161 is disposed on the left side in FIG.

  The frame ground FG terminal 181a of the connector 181 is connected to a printed connection 224 on the back surface of the detection circuit board 201 shown in FIG. 10 through a through hole 211a. Accordingly, the print connection 224 is equipotential with the frame ground. The detection circuit 191 is connected to the frame ground FG by the frame ground FG terminal 181a.

  Between the printed connection 224 and the printed connection 221, electrodes printed with a concavo-convex copper foil are provided so as to face each other, and a microgap 222 is formed. In FIG. 10, a microgap 222 composed of four electrodes (four pairs of concave and convex electrodes) is formed, and the distance from the end of the convex portion to the bottom surface of the concave portion (interelectrode distance) is approximately 0.2. It is set to about mm.

  The circuit ground terminal 181b of the connector 181 is connected to the printed connection 225 on the back surface of the detection circuit board 201 shown in FIG. 10 through the through hole 211b. Therefore, the printed connection 225 is equipotential with the circuit ground.

  Between the print connection 225 and the print connection 224, electrodes printed with a concavo-convex copper foil are provided so as to face each other, and a microgap 223 is configured. In FIG. 10, a microgap 223 composed of four electrodes (four pairs of concave and convex electrodes) is formed, and the distance from the end of the convex portion to the bottom surface of the concave portion (interelectrode distance) is approximately 0.2. It is set to about mm.

  The output terminal 181 c of the connector 181 outputs the human body contact detection result output from the detection circuit 191 to the control unit 122. The power supply terminal 181d of the connector 181 receives power for driving the detection circuit 191 from the power supply 248 (FIG. 11). The power source 248 is shown as one that outputs a DC power source adjusted by the power source 121, and is substantially the power source 121.

  The print connections 211c to 211e in FIG. 9 are formed of holes through which the projecting terminals 161e to 161g of the microswitch body 161 can pass, and the projecting terminals 161e to 161g penetrating through the holes are connected to the print connections 211c to 211c by solder. 211e is connected. Further, the printed connections 211c to 211e are subjected to through-hole processing (processing for electrically connecting the front and back of the detection circuit board 201).

  When the micro switch 161b is turned on (when the stop button 153 is pressed in the direction of the axis 152, the free end portion of the micro switch operation unit 161a is pressed in the direction of the axis 152, and the micro switch 161b is moved to the micro switch body 161. When pressed in, the microswitch body 161 operates so that the print connections 211c and 211e are not electrically connected. Conversely, when the micro switch 161b is in an off state (when the micro switch 161b is pushed out of the micro switch body 161 without being pushed in the direction of the axis 152 by the free end of the micro switch operation unit 161a). The printed connections 211c and 211e are electrically connected internally so as to be short-circuited, and the printed connection 221 on the back surface and the resistor 193 on the upper surface portion are connected.

  If the wiring by the thin film printing of the above detection circuit board | substrate 201 is put together in a circuit diagram, it will become a structure as shown in FIG.

  That is, the metal plate 173 and the print connection 221 are electrically connected by being energized while being in contact with each other so as to face each other. Further, the printed wiring 221 is connected to the microswitch body 161 on the upper surface portion from the back surface portion of the detection circuit board 201 through the through hole 211e (in the normal state in which the microswitch 161b is not pressed, the through holes 211e and 211c are electrically connected. When the micro switch 161b is pressed, the through holes 211e and 211c are not connected to each other), and the resistor 193 and the capacitor 192 are connected to the detection circuit 191. On the other hand, a micro gap 222 is provided between the printed connection 221 and the printed connection 224 on the back surface of the detection circuit board 201. In FIG. 11, the frame ground FG shows a case where the frame ground FG terminal 181a of the connector 181 is connected (ground bonded) to the glass door reinforcing plate 106 grounded via the ground wiring 132. Alternatively, it may be connected to other frame ground FG.

  The detection circuit 191 is connected to the circuit ground of the power supply 248 via the circuit ground terminal 181b of the connector 181. Further, a micro gap 223 is formed between the printed connections 224 and 225 on the back surface of the detection circuit board 201. ing.

  The detection circuit 191 receives the supply of the DC power supplied from the power supply 248 via the power supply terminal 181d of the connector 181, and the resin corresponding to the capacitance of the capacitor 192 (the human body grips the handle main body 112 to An oscillation signal (according to the changing capacitance of the capacitor 192) is generated as a human body contact detection result via the molding member 150, the metal plate 173, the printed connection 221, the micro switch body 161, and the resistor 193, and the connector 181 The voltage is supplied to the control circuit 122 via the output terminal 181c.

  The control circuit 122 is driven by a DC power source supplied from the power source 121 (248), and determines whether or not a human body has come into contact with the handle body 112 based on an oscillation signal supplied from the detection circuit 191. Control the operation of the launcher.

  Next, the configuration of the detection circuit 191 will be described with reference to FIG.

  The power supply circuit 241 supplies power of a predetermined voltage for driving the oscillation circuit 242, the detection circuit 243, the integration circuit 244, the comparison circuit 245, and the output circuit 246.

  The oscillation circuit 242 generates an oscillation signal having a sine waveform having a predetermined frequency based on the change in capacitance based on the charging voltage of the capacitor 192 and outputs the oscillation signal to the detection circuit 243. More specifically, when the player holds the handle body 112, the resin molded member 150, the metal plate 173, the print connection 221, the microswitch body 161 (when the microswitch body 161 is on), and the resistor 193 When the capacitance of the capacitor 192 changes via the oscillation circuit 242, the oscillation circuit 242 does not oscillate the oscillation signal. On the other hand, when the player does not hold the handle and the capacitance of the capacitor 192 does not change, or when the microswitch 161 main body is off, the capacitance of the capacitor 192 does not change. Oscillates an oscillation signal with a sine waveform of frequency.

  The detection circuit 243 detects the oscillation signal generated by the oscillation circuit 242 and supplies the detection result to the integration circuit 244. The integration circuit 244 integrates the detection result supplied from the detection circuit 243 to smooth the result, and supplies the result to the comparison circuit 245. The comparison circuit 245 compares the integrated (smoothed) detection result signal supplied from the integration circuit 244 with a predetermined threshold value, and generates two types of signals when the threshold value is larger or smaller than the threshold value. To the output circuit 246. The output circuit 246 outputs a signal to the subsequent stage from the output terminal 181c in the case of the first signal among the two types of signals supplied from the comparison circuit 245, and stops the signal in the subsequent stage in the case of the second signal. As a result, when an oscillation signal is generated by the oscillation circuit 242, a rectangular waveform corresponding to the generated sine waveform is generated and output from the output terminal 181c.

  The distance between the electrodes of the micro gaps 222 and 223 determines the breakdown voltage based on the distance. Therefore, the distance is set so as to set a breakdown voltage lower than the breakdown voltage of the circuit to be protected. There is a need.

  Next, human body contact detection processing by the touch switch 163 will be described with reference to the flowchart of FIG. The explanation of the processing in the flowchart of FIG. 12 is for explaining the electrical operation of each circuit according to the conditions. Each circuit does not judge the processing of each step or execute each processing. Absent.

  In step S1, the operation is determined depending on whether or not the potential of the metal plate 173 is an overvoltage. For example, in step S 1, the player does not hold the handle body 112, or even if the player holds the handle body 112, the player itself is not charged with static electricity that generates an overvoltage. In such a case, the operation proceeds to step S2.

  In step S2, the operation is determined depending on whether or not the microswitch body 161 is in an on state. That is, if the microswitch body 161 is on, the stop button 153 is not pressed in the direction of the axis 152 by the player, and therefore the microswitch operation unit 161a is not pressed. The micro switch 161b is also not pressed, and the through holes 211c and 211e are electrically connected. Thus, if the microswitch body 161 is on, the process proceeds to step S3.

  In step S3, the operation is determined depending on whether or not a human body has touched. For example, when the player does not hold the handle body 112, the operation proceeds to step S4.

  In step S4, the detection circuit 191 generates an oscillation signal having a constant frequency and supplies it to the control unit 122, and the processing returns to step S1. More specifically, the oscillation circuit 242 of the detection circuit 191 is driven based on the DC power supplied from the power supply 248 via the power supply terminal 181d of the connector 181, based on the power supplied from the power supply circuit 241. Based on the change in capacitance based on the charging voltage 192, an oscillation signal having a sine waveform having a predetermined frequency is generated and output to the detection circuit 243. The detection circuit 243 detects the signal generated by the oscillation circuit 242 and supplies the detection result to the integration circuit 244. The integration circuit 244 integrates the detection result supplied from the detection circuit 243 to smooth the result, and supplies the result to the comparison circuit 245. The comparison circuit 245 compares the signal that is the integrated detection result supplied from the integration circuit 244 with a predetermined threshold value, generates two types of signals for each of cases where the threshold value is larger and smaller than the threshold value, and outputs them to the output circuit 246. To do. The output circuit 246 outputs a signal to the subsequent stage from the output terminal 181c in the case of the first signal among the two types of signals supplied from the comparison circuit 245, and stops the signal in the subsequent stage in the case of the second signal. As a result, when an oscillation signal is generated by the oscillation circuit 242, a sine waveform generated according to the capacitance is output as a rectangular waveform from the output terminal 181c and output to the control circuit 122.

  As a result, since the control circuit 122 is supplied with an oscillation signal having a predetermined frequency, it is determined that the human body is not gripping (not touching) the handle body 112, and whether the operation knob 113 is rotated. Regardless of whether or not, the game ball launching device is controlled so as not to fire the game ball.

  On the other hand, in step S3, for example, when the player is holding the handle body 112, the process of step S4 is skipped, and the process returns to step S1. More specifically, at this time, when the player holds the handle body 112, the metal plate 173, the printed connection 221, the through hole 233, the resistor 193, and the capacitor 192 that have the same potential as the surface portion of the handle body 112 are removed. Thus, since the change in the capacitance between the human body and the earth is transmitted to the oscillation circuit 242, the detection circuit 191 generates an oscillation signal having a predetermined frequency corresponding to the changed capacitance. However, in actuality, the oscillation circuit 242 stops the generation of the oscillation signal in the capacitance that changes due to contact with the human body (for this reason, the process of step S3 is skipped in the flowchart). Is expressed). As a result, the control circuit 122 is not supplied with an oscillation signal having a predetermined frequency. Therefore, the control circuit 122 determines that the human body is holding (contacting) the handle body 112 and the rotation angle of the operation knob 113 is determined. Based on the signal according to the above, the launching device of the game ball is controlled so as to fire the game ball by operating the launch motor and the launch cam.

  In step S2, if the micro switch 161b is off, that is, the stop button 153 is pressed in the direction of the axis 152 by the player, and therefore the micro switch operation unit 161a is also pressed. Therefore, the micro switch 161b Is pressed, the through holes 211c and 211e are not electrically connected. Thus, when the microswitch body 161 is off, the process of step S3 is skipped, and the process proceeds to step S4.

  That is, normally, when the player holds the handle main body 112 and does not operate the stop button 153 by the processing of steps S1 to S4 described above, the operation knob 113 is rotated. When the game ball is fired and, conversely, when the player is not holding the handle body 112 or when the stop button 153 is operated, the game ball is not rotated even if the operation knob 113 is rotated. Operated so that it is not fired.

  By such an operation, for example, even if the player performs an act of fixing the operation knob 113 in a state where the operation knob 113 is rotated to a predetermined rotation angle by an unauthorized method, the game ball may not be fired. It is possible to prevent an illegal act such as launching a game ball without gripping the handle main body 112. Further, it is possible to prevent the player from firing the game ball by pressing the stop button 153 while holding the handle body 112 and maintaining the operation knob 113 rotated at a predetermined rotation angle. it can.

  Therefore, when the micro switch 161b is opened, the detection circuit 191 and the metal plate 173 are disconnected, and the oscillation circuit 242 has an oscillation signal having a predetermined frequency as in the state where the player does not hold the handle body 122. Is generated. For this reason, the power supply to the detection circuit 191 does not stop even for a moment without being affected by the opening / closing of the microswitch 161b. As a result, since the start / stop associated with the turning on / off of the power in the detection circuit 191 does not occur, the generation of an unstable signal that tends to occur at the time of start-up is suppressed. It becomes possible to suppress. In addition, since an oscillation signal is emitted from the detection circuit 191 as a condition for launching the game ball, it is possible to accurately identify and control human contact and the stop button 153 (on / off of the micro switch 161b). Become.

  In addition, as described with reference to FIG. 15, the detection circuit 191 has a high-frequency amplitude detection smoothing function of an oscillation circuit such as the integration circuit 244. The microswitch body 161 is provided in front of the oscillation circuit 242. For this reason, even if chattering occurs during the on / off operation of the micro switch 161b, the integration circuit 244 smoothes the so-called waveform breakage, and the micro switch is a contact switch. The operation of 161b can be stabilized.

  In the above description, the case where the contact-type microswitch 161b is used has been described. However, the microswitch 161b may be configured by a contactless electronic switch for the above-described reason. Good.

  On the other hand, when the potential of the metal plate 173 is an overvoltage in step S1, that is, for example, when a human body (player) having a large capacity of static electricity holds the handle main body 112, the operation is as follows. Proceed to S5.

  In step S <b> 5, the static electricity charged on the human body (player) is discharged between the electrodes of the microgap 222. That is, since the static electricity charged in the human body exceeds the dielectric breakdown voltage between the electrodes constituting the micro gap 222 after energizing the handle main body 112, the metal plate 173, and the print connection 221 held by the human body, Discharge occurs between the electrodes constituting the micro gap 222 and reaches the frame ground FG terminal 181 a of the connector 181.

  In step S <b> 6, it is determined whether the frame ground FG has a lower impedance than the microgap 223. Since the frame ground FG is normally grounded and has a lower impedance than the micro gap 223, the operation proceeds to step S7, and the overvoltage static electricity is generated by the glass door reinforcing plate constituting the frame ground FG. It discharges to the ground through 106.

  That is, since the circuit between the electrodes of the microgap 222 in step S5 has a lower impedance than the resistor 193, static electricity does not flow through the resistor 193 through the through-hole 233 (wereaked by the resistor 193). Almost the entire amount is discharged to the glass door reinforcing plate 106 forming the frame ground FG via the print connection 221, the micro gap 222, the print connection 224, the through hole 231, and the frame ground FG terminal 181a.

  For this reason, the detection circuit 191 can be shielded from static electricity that causes electrostatic breakdown, and as a result, the detection circuit 191 can be protected.

  Furthermore, since the static electricity is not discharged to the circuit ground, for example, it is possible to suppress electrostatic breakdown caused by the backflow of static electricity from the circuit ground to the power supply 248 and the control circuit 122 in the subsequent stage. Not only the detection circuit 191 but also the entire circuit of the pachinko gaming machine 100 can be protected.

  Further, as shown in FIGS. 9 and 10, the detection circuit board 201 is fixed in the positional relationship from the print connection 221 to the print connection 224 having the same potential as the frame ground FG. Capacitance can be kept to a minimum (the stray capacitance itself can be minimized, and the change in stray capacitance according to the position of the wiring can be minimized), resulting in a decrease in detection accuracy as a touch switch (detection accuracy) Variation).

  In step S7, when all static electricity is discharged to the glass door reinforcing plate 106 constituting the frame ground FG, the process returns to step S1. If the impedance of the frame ground FG is not lower than that of the microgap 223 in step S5, the operation proceeds to step S8.

  The static electricity charged in the human body (player) in step S8 energizes the microgap 223 and discharges to the circuit ground in step S9.

  That is, when the impedance of the frame ground FG is not lower than that of the microgap 223, the static electricity exceeds the breakdown voltage between the electrodes constituting the microgap 223, and therefore discharges between the electrodes constituting the microgap 223. . In this case, static electricity is discharged to the circuit ground via the printed connection 225, the through hole 221b, and the circuit ground terminal 181b.

  For example, when the ground wire 132 is not properly grounded, in step S6, the frame ground FG may have a higher impedance than the microgap 223 (normally, the ground wire 132 is not grounded). However, since the glass door reinforcing plate 106 constituting the frame ground FG has a large surface area, the impedance is low). Thus, when the frame ground FG has a higher impedance than the microgap 223, static electricity is discharged to the circuit ground via the microgap 223. As a result, at least the detection circuit 191 can be protected.

  In the micro gaps 222 and 223, when static electricity is discharged between the electrodes, a phenomenon that sparks are scattered occurs. However, in the circuits other than the micro gaps 222 and 223 constituting the touch switch 163, the micro gaps 222 and 223 (The micro gaps 222 and 223 are disposed on the back surface of the detection circuit board 201 shown in FIG. 10, and other configurations are shown in FIG. 9. Therefore, it is possible to suppress damage to other circuits caused by sparks scattered between the electrodes of the micro gaps 222 and 223.

  In addition, because of the characteristics of the microgap, any one electrode is worn every time discharge occurs. Therefore, the life of the microgap having a high discharge frequency can be increased by increasing the number of electrodes. You may do it.

  Furthermore, normally, it is expected that the microgap 222 used for discharging to the glass door reinforcing plate 106 constituting the frame ground FG is higher than the frequency of use of the microgap 223. Therefore, in this embodiment, as shown in FIG. 8, the number of electrodes of the microgap 222: the number of electrodes of the microgap 223 = 4: 4. A configuration may be adopted in which the number of electrodes of the high microgap 222 is increased and the number of electrodes of the microgap 223 that is not frequently used is decreased.

  In the above description, the distance between the electrodes constituting the micro gaps 222 and 223 is 0.2 mm. However, the distance between the electrodes may be changed according to the withstand voltage of the circuit to be protected. On the other hand, the distance between the electrodes may be increased, and the distance between the electrodes may be decreased for a low breakdown voltage circuit.

  In the above description, as shown in FIG. 11, the example in which the micro switch 161b is provided in the front stage of the resistor 193 has been described. For example, as shown in FIG. 13, it may be between the capacitor 192 and the detection circuit 191, or as shown in FIG. 14, between the resistor 193 and the capacitor 192. It may be.

  In FIG. 11, the micro gap 223 is provided between the circuit ground on the cold side of the power source 248 and the frame ground FG. However, the present invention is not limited to this. It may be between the power supply terminal 181d of the connector 181 and the frame ground FG.

  Furthermore, in the above description, the case where the 3-wire touch switch 163 (3-wire detection circuit 191) is used has been described. However, the 2-wire system (two-wire: power supply and circuit ground two wires) is used. In addition, a method of controlling the flow of current for power supply to generate a signal output of a human body contact detection result may be used.

  Here, with reference to FIG. 15, a configuration in the case where the two-wire touch switch 163 is used will be described. In addition, about the structure corresponding to the structure demonstrated with reference to FIG. 11, the same code | symbol is attached | subjected and the description is abbreviate | omitted suitably. The two-wire detection circuit 191 in FIG. 15 differs from the detection circuit 191 in FIG. 11 in that an output circuit 301 is provided instead of the output circuit 246, and not only the microgap 223 but also the microgap 223a. , 223b.

  The output circuit 301 basically has the same function as the output circuit 246, but generates a rectangular wave with a predetermined frequency by controlling the output itself of the power supply circuit 241 based on the comparison result from the comparison circuit 245. As a result, the detection result as the detection circuit 191 is output.

  Further, the function of the microgap 223a of FIG. 15 is equivalent to that of the DC three-wire touch switch of FIG. 11, but the insertion method is different for the backup microgap 223b. That is, in the two-wire touch switch 163 of FIG. 15, since the current change of the external load resistor 247 is output as an output signal, it is basically connected to either of the two connection lines (for power supply and circuit ground). Even if the load resistor 247 is connected, the load resistor 247 functions. However, the impedance of the connecting line portion changes depending on the connection state, so that a difference occurs in the path for discharging static electricity.

  Accordingly, in the two-wire touch switch 163, if the micro gaps 223a and 223b are inserted into either of the two power supply lines, static electricity is discharged through a path not connected to the load resistor 247. It will be. A Zener diode 251 in FIG. 15 is a protective diode of the detection circuit 191 and further strengthens the countermeasure against static electricity of the micro gaps 222, 223a, and 223b.

  Further, since the microswitch body 161 is only connected by the copper foil pattern on the detection circuit board 201, for example, wiring corresponding to the connection line 12a in FIG. Since the capacitance can be reduced, variation in detection accuracy of the touch switch 163 can be suppressed and the number of parts can be reduced, so that the cost of the touch switch 163 can be reduced. It becomes.

  In the above description, the touch switch 163 has a shape as illustrated in FIG. 7. However, the touch switch 163 is parallel to the metal plate 173 with respect to the bottom surface portion 151 of the resin molding member 150. The metal screws 162a and 162b are passed through the hole portions 173a and 173b of the metal plate 173 so as to face the bottom surface portion 151 and are screwed to the bottom surface portion 151 while being in contact with each other. If so, the shape may be other shapes.

  16 to 18 show examples in the case where the touch switch 163 has other shapes. 16 is an exploded view of the touch switch 163 having other shapes, FIG. 17 is an external perspective view of the touch switch 163 having other shapes, and FIG. 18 is a touch switch 163 having other shapes. These are figures explaining the state attached to the bottom face part 151. FIG.

  The metal plate 273 is provided at a substantially central end portion in the longitudinal direction of the upper surface portion of the case 271a in the drawing of the touch switch 163 of FIG. The microswitch body 261 is disposed on the side surface of the end portion in the longitudinal direction of the touch switch of FIG. 17, and is operated by the microswitch operation unit 262a in the direction of the arrow in the figure, and the microswitch operation unit 262a is When pressed against the main body side surface of 163, the micro switch 262b is pressed, the micro switch main body 262 is turned off (the state where the through holes 211c and 211e are not conductive), and the micro switch 262b is turned on. In other states, the micro switch 262 is in an ON state (a state in which the above-described through holes 211c and 211e are electrically connected).

  As shown in FIG. 16, when the metal plate 273 is inserted into the resin case 271 a into the key-shaped grooves 344 a and 344 b that are substantially the same as the convex shape of the metal plate 273, the hole portion 341 of the metal plate 273. And the hole 342 of the case 271a are fixed at substantially the same position.

  At this time, the case 271a and the cover 271b are the upper surface portion of the detection circuit board 401 in FIG. The pattern forming the same circuit, which is different from the pattern of the upper surface portion of the detection circuit board 201 shown in FIG. 9, is the back surface portion of the detection circuit board 401 in FIG. , 301b are inserted into the holes 311a and 311b of the microswitch body 261 and fixed so that the surface of the microswitch body 261 provided with the microswitch 261b and the end of the case 271a coincide. Further, at this time, the claws 321a to 321d of the case 271a are engaged with the holes 331a to 331d of the cover 271b as shown in FIG. 17, thereby locking the case 271a and the cover 271b. The detection circuit board 401 is fixed.

  When the case 271a and the cover 271b sandwich the detection circuit board 401 in this way, the printed wiring of the upper surface portion (a pattern constituting a circuit similar to the pattern shown in FIG. 10) of the detection circuit board 401 in FIG. 221 contacts the metal plate 273. As a result, similarly to the touch switch 163 in FIG. 7, the metal plate 273 and the detection circuit board 401 are electrically connected.

  Further, the connector 281 is inserted from the back side of the detection circuit board 401 in FIG. 16 to the upper side in FIG. 16, and the convex terminals 261c to 261f are fixed in a state of penetrating the upper surface part of the detection circuit board 401 in FIG. Are electrically connected. The connection between the detection circuit board 201 and the convex terminals 261c to 261f is the same as the connection method between the microswitch body 161 and the detection circuit board 201 in FIG.

  Further, the detection circuit board 401 is provided with a recess 351 having a diameter larger than the diameter of the hole 342 coaxially with the hole 342 of the case 271a. Further, the cover 271b is also provided with a recess 361 having a diameter larger than the diameter of the hole 342 coaxially with the hole 342 of the case 271a.

  With such a configuration, as shown in FIG. 18, the touch switch 163 shown in FIGS. 16 to 18 is in contact with the top surface portion of FIG. 17 and the bottom surface portion 151 of the resin-molded member 150 plated with metal. In the state where the micro switch operation part 262a is in the direction facing the stop button 153, the metal screw 162 passes through the recess 361 and the hole part 342 from the upper part to the lower part in FIG. It is fixed by being screwed to 151. By being fixed in this way, the handle body 112 and the touch switch 163 are electrically connected to each other because the portion of the metal plate 273 exposed from the case 271a is fixed in contact with the bottom surface portion 151. Connected.

  Therefore, a change in capacity corresponding to the presence or absence of human body contact with the handle body 112 and the resin molding member 150 is transmitted to the detection circuit 191 of the touch switch 163.

  As described above, although the appearance of the touch switch 163 in FIGS. 16 to 18 is significantly different from that of the touch switch 163 in FIGS. 5 to 8, the contact surfaces of the metal plates 173 and 273 and the micro switches 161b and 262b respectively. The operation direction is parallel, and the direction in which the metal screws 162a, 162b, 162 are inserted and the direction in which the connector 182 is inserted into the touch switch 163 are perpendicular to the contact surfaces of the metal plates 173, 273. It is the same.

  As a result, the player can use the stop button 153 by using at least one of the fingers of the hand holding the handle body 112 while maintaining the state of holding the handle body 112 substantially. Since it becomes possible to operate, the stop button 153 can be easily operated.

  Further, when the touch switch 163 is attached to the handle unit 111, the metal switch 162 is inserted into the resin molding member 150 in the vertical direction and fixed by being screwed to the resin molding member 150. At the same time, the metal plate 173 is electrically connected. In addition, the movable direction of the stop button 153 and the operation direction of the micro switch body 161a can be matched. Further, when the metal screw 162 is screwed to the resin molded member 150, the connectors 281 and 182 are connected to each other. For this reason, the connection between the connectors 281 and 182 can be facilitated. In addition, since the touch switch 163 is integrally formed with the micro switch body 161, the micro switch body 161 can be fixed at the same time only by fixing the touch switch 163.

  As a result, the number of work steps in the work of attaching the touch switch 163 to the handle unit 111 can be reduced, and it can be ensured. Further, by reducing the number of parts, the apparatus can be reduced in size and simplified.

  Note that the touch switch 163 in FIGS. 16 to 18 is the same as the touch switch 163 described with reference to FIGS.

  In the above, an example using a micro gap as a circuit protection element has been described. However, other circuit protection elements may be used, for example, an arrester or a varistor is used. It may be.

  Further, in the above description, an example in which a change in the capacitance between the ground due to contact with the human body is detected from the handle main body 112, the metal plate 173, and the printed connection 221, the printed connection 221 is configured as a terminal of the connector 181. Anyway. However, in this case, since wiring from the handle body 112 or the metal plate 173 is required, it is necessary to consider the stray capacitance due to the wiring. Further, the print connection 221 may be configured as the handle main body 112 as it is (the handle main body 112 may be a part of the copper foil pattern constituting the print connection 221).
