Description
Technical field
The present invention relates to contact sense apparatus for human body, particularly, relate to the contact detection action that stably realizes human body, the accuracy of detection that can suppress the human body contact simultaneously reduces (inhibition deviation), and can prevent the destruction of static, and then can carry out the contact sense apparatus for human body of fitting operation easily to device.
Background technology
In Pinball machine, be purpose with the detection of game ball, the detection of human body (player) or the position probing of structure member etc., using has a large amount of switches.Wherein, begin in the action that makes Pinball machine begin to move under the situation of switch (Move Zuo Qi Machine ス イ Star チ), there is contact switch then when opening and closing, to produce unique vibration (チ ヤ Star リ Application グ) owing to use, becomes main flow so use small electronic switch to be substituted with contact switch (contact ス イ Star チ is arranged).As such action opportunity switch, except that detect that game ball passes through near the switch (closely meeting ス イ Star チ), recently, researching and developing the capacitance type human detection contact-making switch etc. of the static capacity human body contact that use changes based on the handle of the emitter action that is made game ball by player contact.
The human detection contact-making switch is meant, when the metal plate that human body (directly or indirectly) contact sets in advance, based on changes in capacitance between the earth of this plate, judges that whether human body contacts, and exports judged result as signal.
In addition, the emitter with respect to Pinball machine is set,, uses the shutdown switch that contact type is arranged as this function while the player holds the function that handle stops the emission of game ball by its intention.
Therefore, discretely in handle main body the human detection contact-making switch is set and as while holding the shutdown switch (ス ト Star プ ス イ Star チ) that the intention of handle by the player makes the function that the emission of game ball stops, switch the power supply state of human detection contact-making switch by the break-make of microswitch, thereby (for example, with reference to patent documentation 1,2) oversimplified in the processing of the action of human detection contact-making switch and shutdown switch.
In addition, when this human detection contact-making switch is imported Pinball machine inside, need to implement the static countermeasure.
That is, contact with contact-making switch player's (human body) of the static electrifications such as situation in winter, or approaching with contact-making switch, produce thus the contact-making switch static discharge.The static discharge voltage of this moment is for example in the situation of human locomotion on flannelette blanket of wear wool fabric etc. etc. even can reach tens thousand of volts.Usually, the static endurance of electronic switch is obviously low than the endurance that contact switch is arranged, and when the overvoltage of above-mentioned such generation of static electricity was discharged in contact-making switch, the electronic unit of inside may be by electrostatic breakdown.Therefore, this human detection touch switch circuit on the basis of the structure of carrying out the detection action whether human body contact, need with the structure coexistence of carrying out the electrostatic protection action.
Static countermeasure about small electronic switch; even invade circuit inside at the static that the human body and the contacted while of the detecting electrode that contacts of human body are charged; also can form the discharge route of directly connecting by protecting component and circuit ground; thereby; static immediately to the external discharge of contact-making switch, is restrained the influence (for example with reference to patent documentation 3) to the low position of static endurance such as oscillating circuit by circuit ground.
In addition, replacing the discharge route to circuit ground, is frame ground discharge (for example with reference to patent documentation 2) to the ground connection position more stable than circuit ground.

At this, explanation has the contact-making switch of above-mentioned shutdown switch with reference to Fig. 1.
Contact-making switch 1 is located in the handle main body pedestal B of operating grip of the game ball that is used to launch Pinball machine.The testing circuit 15 of contact-making switch 1 is disposed on the circuit substrate 16, the electric power of being supplied with by the control substrate 5 of the various functions such as emission of controlling game ball drives, utilize the contact of contact antenna 11 human body, then the contact detection signal is supplied on the control substrate 5 by connector 13 and electrical path 4.In more detail, the terminal 13a of bonder terminal 13 is made of the holding wire and the ground wire of electric power supply line, transmission testing result, and the driven by power that testing circuit 15 is supplied with by connector 13 outputs to testing result on the control substrate 5 by connector 13.
Control substrate 5 is supplied with the signal that expression has detected the human body contact based on the testing result of supplying with from contact-making switch 1, and then drive motor M launches game ball in not shown Pinball machine.
Between testing circuit 15 and connector 13, be provided with connector 14, connecting line 12a and shutdown switch 12.Shutdown switch 12 disconnects when the player desires to make the emission of game ball to stop, and in the time, is the state of connecting in addition.Switch 12 forms following structure: when on-state, will directly output on the connector 13 from the output result who detects path 15; When disconnecting, interdict the contact detection signal forcibly.Whether its result under the state that switch 12 disconnects, contacts human body no matter control substrate 5 forms contact antenna 11, always do not supply with the state of human body contact detection signal from testing circuit 15.Therefore, owing to motor M is not driven yet, so force to stop the emission of game ball.
In addition, contact antenna 11 via distribution 2 and by the discharger substrate 3 that is provided with discharger 3a ground connection.
As shown in Figure 1, the mechanism that stops as the emission that makes game ball is provided with shutdown switch 12 on the power supply supply passageway of testing circuit 15, switch state by the break-make of shutdown switch 12, thereby the emission control of the game ball of Pinball machine is oversimplified to testing circuit 15 power supply.But, switching is when the state of testing circuit 15 power supply, until certain hour to testing circuit 15 comprehensive supply powers, owing to be the state that can not guarantee to control the circuit operation on the substrate 5, produce the misoperation pulse so have when the power supply of testing circuit 15 inserts, or the problem of the output delay zero hour of standard signal.
In addition, 12 uses have contact switch to switch under the situation of power supply state as shutdown switch, are supplying with to the power supply of testing circuit 15 and are coming can produce vibration in the output signal of self-detection circuit 15, its result must be provided as the structure of vibrating countermeasure in back segment.
In addition,, be generally the contact-making switch of higher-order of oscillation type as the employed testing circuit 15 of Pinball machine, for example, in the situation of the contact-making switch 1 (with reference to patent documentation 2) of direct current two-wire system; Shutdown switch 12 forms leaves state (off-state), stops the situation to the power supply state of testing circuit 15; And contact-making switch 1 detects under the situation of human body contact, has the problem of the differentiation difficulty on the control circuit 5 of back segment.
Promptly, under the situation of the higher-order of oscillation type contact-making switch 1 of the testing circuit 15 that uses the direct current two-wire system, when testing circuit 15 contacts with contact antenna 11 at human body, by applying electrostatic capacitance, the vibration of inner not shown oscillation circuit is stopped, and the result forms the state that action stops.In addition, testing circuit 15 becomes the state that does not apply electrostatic capacitance when human body does not contact with contact antenna 11, and by the signal of the not shown oscillation circuit vibration assigned frequency of inside, the result forms the state of action beginning.
At this moment, even the action at testing circuit 15 is the state that stops, in order to make the prior action of circuit certain electric current (being commonly referred to as leakage current) that expends that also circulates, on the contrary, even in the action that detects electric current 15 is the state of beginning,, the holding circuit action decides voltage (being commonly referred to as residual voltage (residual Electricity presses)) for also existing certain inside.
Because the leakage current and the residual voltage of the contact-making switch 1 of the higher-order of oscillation type of direct current two-wire system (direct current 2 Line formulas) all must minimize, so be the situation of off-state (opening state) at testing circuit 15, current sinking minimizes.As a result, during human body contact detection under the few vibration halted state of current sinking, testing circuit 15 is set to off-state.
Be envisioned that following problem: testing circuit 15 is the situation of off-state (opening state) when the human body contact detection, the structure that the action of testing circuit 15 is stopped is possible, but leakage current is the characteristic of Da Yi generation deviation very, is difficult to the control of moving.
Therefore, the testing circuit 15 of the detected state of contact-making switch 1 when the human body contact detection is under the situation of off-state, even the power supply state of contact-making switch 1 is switched to halted state, owing to only become the off-state of testing circuit 15 and the non-action status that stops to the power supply of contact-making switch 1, so it is difficult in the extreme on this difference of differentiation, as a result, having with the Pinball machine is irrealizable problem in the function reality of shutdown switch 12 of purpose.
In addition, in Fig. 1, be provided with outward by the shutdown switch 12 that has contact switch to constitute, but the connecting portion as contact-making switch 1 increases (connector 13,14), in fact contact-making switch 1 maximizes, be difficult in the reality be provided with in the handle main body in narrow space, simultaneously along with the increase of connector quantity, making the operation and the cost that are spent increases.
In addition, the result who increases as the connection of contact-making switch 1, owing to do not cut down number of components, so can not seek simplification as the handle main body of main purpose.
The shutdown switch 12 that has contact switch to constitute has above-mentioned all unfavorable conditions owing to being contemplated to when inserting the position that directly opens and closes the electric power supply line, consider to have the structure of the small signal circuit switching that makes testing circuit 15 inside so replace it, but insert by the shutdown switch 12 that has contact switch to constitute in the inside of the testing circuit 15 that constitutes by the electrostatic capacitance high-frequency oscillating circuits, then owing to ask by the earth of the shutdown switch 12 that has contact switch to constitute self and electrostatic capacitance that electric capacity and the stray capacitance relevant with connecting line 12a become oscillating circuit to detect the main cause of flutter (particularly connecting line 12a's draws winding method, the influence of metal on every side and with on each handle, all may the changing of other distributions near situation etc.), so the deviation of the action of contact-making switch 1 is increased.
In addition, carrying on the Pinball machine under the situation of above-mentioned contact-making switch, producing has the new problem relevant with static.
Promptly, structure according to contact antenna 11 shown in Figure 1, for example when the player of static electrification contacts the metal part of handle main body pedestal B, testing circuit 15 reactions, having has no signal to be sent to the function of controlling on the substrate 5 the human body contact, simultaneously, human body with static also discharge to handle main body pedestal B.
In this case, for example in the contact-making switch 1 of Fig. 1, can't help contact antenna 11 and connect distributions 2, discharger substrate 3, in addition, as the static countermeasure, be during directly to the structure of circuit ground discharge, above-mentioned static sees through testing circuit 15, by electric path 4, arrives on the control substrate 5.Its result can cause the generation etc. of the electrostatic breakdown of control substrate 5, the undesirable condition of the position outside the contact-making switch 1.That is, make static when circuit ground is discharged,, might cause harmful effect in other position of Pinball machine though can produce circuit protection to contact-making switch 1 by static.
Therefore, as shown in Figure 1, in contact-making switch 1,, implement the protection of discharger 3a as the electrostatic breakdown countermeasure of control substrate 5.That is, connect a side end of discharger substrate 3, the end of discharger 3 opposite sides is connected with frame ground FG in the metal part of the contact antenna 11 of handle main body pedestal B.Discharger substrate 3 itself is disposed in the handle main body pedestal B, perhaps is disposed at the flip football pusher side by distribution 2.
Here the ground connection of saying to frame ground FG is to point to the connection that is called as the metal framework that has in the Pinball machine of frame ground (calling FG in the following text), be that metal part with housing, card cover or the main body framework of Pinball machine connects in the lump, for preventing accidents such as electric leakage, electric shock, internal circuit is the ground wire that stably guarantees current potential under the state of electric insulation.
That is, the circuit ground current potential of Pinball machine inside constitutes so-called floating (the cosmos To float い) state with the earth insulation, stable anything but earthing potential, and electric capacity determines between the earth that its stability is had by circuit ground.Opposite also can be at the Pinball machine stable just earthing potential of frame ground FG on the whole, in emitting the surge voltage of static etc., be suitable as the final point of arrival.
Therefore, in the contact-making switch 1 on being equipped on Pinball machine, compare, guarantee that discharge route to frame ground FG is with the static countermeasure is relevant more completely with the circuit ground that can not guarantee stability.
That is, as static countermeasure shown in Figure 1, discharger 3a, discharger substrate 3 and distribution 2 with state that frame ground FG is connected under, be connected with contact antenna 11, then can stably protect contact-making switch 1 and Pinball machine by static discharge.But on the other hand, because the stray capacitance that distribution 2 has is attached on the contact antenna 11, so the differences such as collocation method of distribution 2, the accuracy of detection that exists contact-making switch 1 to cause human body to contact reduces (generation deviation) such problem.
In addition, by contact-making switch 1 and shutdown switch 12 are carried out distribution respectively alone, the operational sequence during owing to manufacturing increases, and spends man-hour in the making, makes the number of components increase owing to carrying out distribution separately respectively simultaneously, so have the problem of product cost increase.

In addition, contact-making switch 163 forms and microswitch main body 161 incorporate structures.Microswitch main body 161 is connected on the microswitch operating portion 161a by stop button 153 is pushed to axle 152 directions, in addition, by microswitch operating portion 161a is pushed to axle 152 directions, microswitch 161b is pressed on the microswitch main body 161, under this state, the action of microswitch main body stops.At this moment, contact-making switch 163 produces the signal that the emission that makes game ball stops.
That is, operation knob 113 by not shown spring etc., is to regard the state that stops as the border angle that can be rotated counterclockwise as from the main body front of the Pinball machine 100 of Fig. 2 when the state of not operated by the player.The player is by gripping the clockwise direction rotation of this operation knob 113 in Fig. 2, and handle unit 111 transmits corresponding signal according to the anglec of rotation of operation knob 113 to not shown emitter.Not shown emitter is by control circuit 122 control, and the signal of the anglec of rotation of the respective operations knob of supplying with based on handle unit 111 113 is controlled the intensity of the batting hammer of game ball, emission game ball by making emission motor and emission cam action.
At this moment, by being that axle 152 directions are pushed with stop button 153 direction of arrow in figure aptly, microswitch 161b disconnects, and stops the emission of game ball.In addition, hereafter is by pushing the action that the emission that makes game ball stops with stop button 153 to the direction of arrow.
By above structure, under the situation in contact-making switch 163 is arranged at handle main body 112 (kind according to Pinball machine also has situation about being arranged at outside the handle), stop button 153 can move to the direction (direction of arrow among Fig. 4) of rotating shaft 152.Therefore, microswitch operating portion 161a forms the configuration that the bottom surface sections 151 of relative resin-molded component 150 is operated abreast.That is, more specifically, the operating surface of the face of metallic plate 173 and microswitch operating portion 161a is all parallel with respect to bottom surface sections 151.In addition, the direction of insertion of metal screw-making 162a, 162b is set in respect on the vertical direction of bottom surface sections 151.
The result, the state that the player is roughly keeping gripping handle main body 112 is constant, only use any at least finger of the hand of gripping handle main body 112, just can easily operate stop button 153, therefore, the player can keep the anglec of rotation (emissive porwer of game ball) of the operation knob 113 of the emission game ball oneself set on one side, Yi Bian the emission of game ball is stopped.
In addition, when contact-making switch 163 is installed on the handle unit 111, only vertically insert metal screw-making 162a, 162b and its screw thread is fixed, just be fixed on the resin-molded component 150 and and be electrically connected with metallic plate 173 by relative resin-molded component 150.In addition, can make the movable direction of stop button 153 consistent with the direction of operating of microswitch operating portion 161a.In addition, by with the relative resin-molded component 150 screw thread combinations of metal screw-making 162a, 162b, connector 181, the 182 mutual application of forces.Therefore, can easily and reliably connector 181,182 be connected.As a result, working hour is reduced, simultaneously because microswitch main body 161 and contact-making switch 163 is integrated and can reduce number of spare parts and reduce cost.In addition, by reducing number of components, can be with equipment miniaturization and simplification.In addition, connector 182 is disposed on the vertical direction with respect to bottom surface sections 151.
Next with reference to Fig. 7, Fig. 8 contact-making switch 163 is described.In addition, the contact-making switch 163 of Fig. 7 and Fig. 8 is the figure that reverses in the table with face in mutual accompanying drawing.Fig. 7 is the stereogram of the outward appearance of expression contact-making switch (three-way output four terminals: power supply is used, circuit ground is used, human body contact detection result's signal is exported the three-way of usefulness, and band frame ground FG terminal) 163; Fig. 8 is the exploded view of contact-making switch 163.
Be connected with electronic circuits such as connector 181 and testing circuit 191 on the testing circuit substrate 201 in Fig. 8 on the face by copper foil pattern.In addition, microswitch main body 161 insertion below Fig. 8, the protuberance terminal 161e～161g of microswitch main body 161 is connecting testing circuit substrate 201 and under the outstanding state of upper face side, is electrically connected with the copper foil pattern of upper part among the figure of testing circuit substrate 201.If insert testing circuit substrate 201 after the configuration metallic plate 173 on housing 171a, then back side portion becomes the state that testing circuit substrate 201 is electrically connected with metallic plate 173 with the part of metallic plate 173 by contacting among the figure of testing circuit substrate 201.
Say in further detail, protuberance 171c, the 171d of housing 171a connects the 173c of hole portion, the 173d of metallic plate 173 respectively, and then, connect the 161c of hole portion, the 161d of microswitch main body 161, thereby microswitch main body 161 is by pressured and testing circuit substrate 201 is inserted in the housing 171a to housing 171a side with metallic plate 173.As a result, the printed wiring 221 (Figure 10) of the back side portion of the testing circuit substrate 201 of Fig. 8 described later contacts with metallic plate 173, thereby testing circuit substrate 201 and metallic plate 173 are electrically connected.
In addition; as shown in Figure 8; cover 171b is by direction relative separately among the figure that is pressed into housing 171a; the ratchet 171g (being located at the end of cover 171b), the 171h that are located at cover 171b both ends are engaged with respect to ratchet 171i, the 171j of housing 171a respectively; thus; be limited on the peristome of housing 171a protection testing circuit substrate 201.
Next the circuit pattern of testing circuit substrate 201 is described with reference to Fig. 9, Figure 10.Fig. 9 is the top figure of the testing circuit substrate 201 of Fig. 8; Figure 10 is the back view of the testing circuit substrate 201 of Fig. 8.In Fig. 9,10, the painted scope of horizontal line or ordinate is represented the circuit pattern of Copper Foil among the figure.
As shown in Figure 9, on testing circuit substrate 201, be provided with connector 181, testing circuit 191, input resistance 193 and capacitor 192, as shown in figure 10, form printed wiring 221, the microgap 222,223 that contacts with metallic plate 173 by copper foil pattern overleaf, microswitch main body 161 is disposed at the left part among Fig. 7.
The frame ground FG terminal 181a of connector 181 is connected with the printed wiring 224 of the back side portion of testing circuit substrate 201 shown in Figure 10 by through hole 221a.Therefore, printed wiring 224 becomes equipotential with frame ground.In addition, testing circuit 191 is connected with frame ground FG by frame ground FG terminal 181a.
Subtend ground is provided with the electrode of being printed by concavo-convex Copper Foil between printed wiring 224 and printed wiring 221, constitutes microgap 222.In Figure 10, form the microgap 222 that constitutes by four utmost point electrodes (four pairs of concavo-convex electrodes), the distance (interelectrode distance) of the end of protuberance to the bottom surface of recess is set at about about 0.2mm.
The circuit ground terminal 181b of connector 181 is connected with the printed wiring 225 of the back side portion of testing circuit substrate 201 shown in Figure 10 by through hole 211b.Therefore, printed wiring 225 becomes equipotential with circuit ground.
Between printed wiring 225 and printed wiring 224, the electrode that the subtend setting is printed by concavo-convex Copper Foil constitutes microgap 223.Form the microgap 223 that constitutes by four utmost point electrodes (four pairs of concavo-convex electrodes) among Figure 10, be set at about about 0.2mm from the distance (interelectrode distance) of end to the bottom surface of recess of protuberance.
The lead-out terminal 181c of connector 181 is to the human body contact detection result of control part 122 outputs by testing circuit 191 outputs.The power supply terminal 181d of connector 181 receives the electric power of driving testing circuit 191 usefulness of power supply 248 (Figure 11) supply.In addition, power supply 248 expression outputs are adjusted into dc source by power supply 121, are actually power supply 121.
Printed wiring 211c～211e among Fig. 9 is made of the hole portion that the protuberance terminal 161e～161g of microswitch main body 161 can connect, and the protuberance terminal 161e～161g of through hole portion is connected with printed wiring 211c～211e by scolding tin.In addition, printed wiring 211c～211e implements through hole processing (processing that the table back side of testing circuit substrate 201 is conducted).
When microswitch 161b connects (by stop button 153 is pushed to axle 152 directions, the free end of microswitch operating portion 161a is pushed to axle 152 directions, microswitch 161b is pressed into the situation in the microswitch main body 161), microswitch main body 161 makes and becomes the state that is not electrically connected between printed wiring 211c and the 211e and move.On the contrary, (microswitch 161b does not push to axle 152 directions by the free end of microswitch operating portion 161a when the state that microswitch 161b disconnects, by from microswitch main body 161 by situation about going out), make short circuit between printed wiring 211c and the 211e and connect, be connected between the resistance 193 with the printed wiring 221 at the back side and last face in internal electrical.
The distribution of the film printing of above testing circuit substrate 201 is accumulated circuit diagram, then form mechanism shown in Figure 11.
That is, metallic plate 173 and printed wiring 221 are by the pressured state that is electrically connected that becomes under subtend state of contact mutually.In addition, printed wiring 221 (under the situation of the common state of not pushing microswitch 161b, forms the state with conducting between through hole 211e, the 211c via through hole 221e from the back side portion of the testing circuit substrate 201 microswitch main body 161 by last face; Under the situation of the state of pushing microswitch 161b, form the state between not conducting through hole 211e, the 211c), resistance 193 and electric capacity 192 and be connected with testing circuit 191.On the other hand, printed wiring 221 and the printed wiring 224 of the back side portion of testing circuit substrate 201 between be provided with microgap 222.In addition, represented that in Figure 11 frame ground FG is connected the situation of (earth connection) with the frame ground FG terminal 181a of connector 181 with the glass door stiffener 106 via ground wire 132 ground connection, but also can be connected with the frame ground FG beyond it.
The dc source that control circuit 122 is supplied with by power supply 121 (248) drives, and judges based on the oscillator signal that testing circuit 191 is supplied with whether human body contacts handle main body 112, the action of the emitter of control game ball.
Next the structure of testing circuits 191 is described with reference to accompanying drawing 11.
Oscillating circuit 242 bases produce the sine-shaped oscillator signal of assigned frequency based on the variation of the electrostatic capacitance of the charging voltage of capacitor 192, to detecting circuit 243 outputs.More particularly, by player's gripping handle main body 112, via resin-molded component 150, metallic plate 173, printed wiring 221, microswitch main body 161 (when microswitch main body 161 is connected) and resistance 193, make under the situation of electrostatic capacitance change of capacitor 192, oscillating circuit 242 does not produce oscillator signal.On the other hand, because the player is gripping handle not, the electrostatic capacitance of capacitor 192 does not change, perhaps, the electrostatic capacitance of capacitor 192 does not change under the situation that microswitch 161 main bodys disconnect, so oscillating circuit 242 produces the sine-shaped oscillator signal of assigned frequency.
Detecting circuit 243 detects the oscillator signal that has oscillating circuit 242 to produce, and the detection result is supplied with to integrating circuit 244.Integrating circuit 244 is by detection that detecting circuit 243 is supplied with integration and smoothing as a result, and supplies with to comparison circuit 245.The detection result's who is integrated (smoothing) that comparison circuit 245 is supplied with integrating circuit 244 signal and the threshold ratio of regulation are producing two kinds of signals than big situation of threshold value and the situation littler than threshold value at every turn, and are exporting to output circuit 246.Under the situation of first signal of output circuit 246 in two kinds of signals that comparison circuit 245 is supplied with, to the back segment output signal, under the situation of secondary signal, stop to the back segment output signal from lead-out terminal 181c.As a result, when producing oscillator signal, result from the square waveform of the sinusoidal wave pattern correspondence that is produced, export by lead-out terminal 181c by oscillating circuit 242.
In addition, the interelectrode distance of microgap 222,223 is owing to the breakdown voltage of decision based on this distance, so necessary setpoint distance is lower than the withstand voltage breakdown voltage of desiring holding circuit with setting.
Next is handled with reference to the human body contact detection of the flowchart text contact-making switch 163 of accompanying drawing 12.In addition, the processing spec of the flow chart of Figure 12 illustrates the electrical action of each circuit according to condition, and each circuit is not the processing of carrying out each step, or implements circuit that each is handled.
In step S1, whether be that overvoltage determines action according to the current potential of metallic plate 173.For example, in step S1, no matter the player holds not gripping handle main body 112, player self is not with in the time of producing superpotential static, and this action advances to step S2.
In step S2, whether be that on-state determines action according to microswitch main body 161.Promptly, when microswitch main body 161 is connected, the player is not to axle 152 direction pressing operation stop buttons 153, the microswitch operating portion 161a action that also is not pressed thus, therefore, under the state that microswitch 161b also is not pressed, be the state of conducting between through hole 211c, the 211e, like this, when microswitch main body 161 was connected, its processing advanced to step S3.
In step S3, according to human body whether contact determine the action.For example, not under the situation of gripping handle main body 112, its action advances to step S4 the player.
In step S4, testing circuit 191 produces the oscillator signal of certain frequency, and supplies with to control part 122, and this processing turns back to step S1.In more detail, the oscillating circuit 242 of testing circuit 191 is based on passing through from power supply 248 via the dc source of the power supply terminal 181d supply of connector 181 with based on the power drives of being supplied with by power circuit 241, according to variation based on the electrostatic capacitance of the charging voltage of capacitor 192, produce the sine-shaped oscillator signal of assigned frequency, and to detecting circuit 243 outputs.Detecting circuit 243 detects the signal that is produced by oscillating circuit 242, and the detection result is supplied with to integrating circuit 244.Integrating circuit 244 carries out integration and smoothing by the detection result that detecting circuit 243 is supplied with, and supplies with to comparison circuit 245.Comparison circuit 245 produces two kinds of signals with the detection result's who is integrated of integrating circuit 244 supplies the signal and the threshold of regulation in each situation bigger than threshold value with than the situation under the threshold value, and to output circuit 246 outputs.Under the situation of first signal of output circuit 246 in two kinds of signals that comparison circuit 245 is supplied with, to the back segment output signal, under the situation of secondary signal, stop to the back segment output signal by lead-out terminal 181c.As a result, when producing oscillator signal, export from lead-out terminal 181c as square waveform according to the sinusoidal waveform that electrostatic capacitance produces by oscillating circuit 242, and to control circuit 122 outputs.
This result, control circuit 122 is judged to be human body and does not grip (not contact) handle main body 112 owing to receive the supply of the oscillator signal of assigned frequency, and the emitter of control game ball is not launched no matter whether game ball operation knob 113 is rotated.
On the other hand, in step S3, for example when player's gripping handle main body 112, the processing of skips steps S4, step S1 is returned in this processing.In more detail, at this moment, the player is by gripping handle main body 112, by and the surface element of handle main body 112 constitute idiostatic metal level 173, printed wiring 221, through hole 233, resistance 193 and electric capacity 192 changes in capacitance between the earth of human body be delivered on the oscillating circuit 242, thus, the oscillator signal of the assigned frequency of the electrostatic capacitance of corresponding its variation of testing circuit 191 generations.In the electrostatic capacitance that changes owing to the human body contact, oscillating circuit 242 makes the generation of oscillator signal stop (therefore, showing as the processing of skips steps S3 in flow chart) but in fact.This result is because control circuit 122 does not receive the supply of the oscillator signal of assigned frequency, grip (contact) handle main body 112 so be judged as human body, based on the signal corresponding with the anglec of rotation of operation knob 113, make emission motor and emission cam action, control game ball emitter makes its emission game ball.
In addition, in step S2, the situation that microswitch 161b disconnects, that is, to axle 152 direction pressing operations, then microswitch operating portion 161a's stop button 153 also is pressed by the player, therefore, by pushing microswitch 161b, between through hole 211c, the 211e state of not conducting.Like this, under the situation that microswitch main body 161 disconnects, the processing of skips steps S3, this processing advances to step S4.
That is the processing by above-mentioned step S1～S4 usually.The player is under the state that grips handle main body 112, and under the situation of the state of not operating stop button 153, by making operation knob 113 rotations, the emission game ball, on the contrary, the player perhaps operates under the situation of state of stop button 153 under the state of gripping handle main body 112 not, even make operation knob 113 rotations, game ball can not launched yet.
By such action, even for example the player has carried out the behavior that operation knob 113 fixed with method improperly under the state of the rotation regulation anglec of rotation, also can not make game ball emission, can prevent not gripping handle main body 112 and this behavior improperly of emission game ball.In addition, the player can gripping handle main body 112, keeps the state of operation knob 113 to the rotation of the regulation anglec of rotation, and can not make the game ball emission by pushing stop button 153.
Therefore, in the open situation of microswitch 161b, with testing circuit 191 and metallic plate 173 disjunctions, as oscillating circuit 242, with the player not the state of gripping handle main body 122 similarly produce the oscillator signal of assigned frequency.Therefore, be not subjected to the influence that the switching station of microswitch 161b brings, supply with to the electric power of testing circuit 191 and do not stop for the moment.Therefore as a result, do not stop, so the easily generation of the unsettled signal of generation when suppressing starting, can suppress the influence to control part 122 owing to do not produce the starting that the electric power of following testing circuit 191 is switched on or switched off.In addition, as the condition of emission game ball,, can correctly discern and control the contact and the stop button 153 (connection of microswitch 161b disconnects) of human body owing to produce oscillator signal from detecting electric power 191.
In addition, as the illustrated ground of reference Figure 15, there is the detection smoothing function of the high frequency amplitude of the such oscillating circuit of integrating circuit 244 on the testing circuit 191.In addition, microswitch main body 161 is located at the leading portion of oscillating circuit 242.Thus, even produce vibration during microswitch 161b on-off action,,, make conduct that the action stabilisation of the microswitch 161b of contact switch be arranged so also can suppress so-called Chevron crack (waveform cuts れ) owing to be integrated circuit 244 smoothings.
In addition, the situation of using the microswitch 161b that the contact type is arranged has been described more than, but, obviously also can have constituted by the electronic switch of contactless type by above-mentioned reason as the structure of microswitch 161b.
On the other hand, in step S1, when the current potential of metallic plate 173 was overvoltage, promptly for example with the human body gripping handle main body 112 of the static of big electric capacity the time, this action advanced to step S5.
In step S5, human body (player) with static between the electrode of microgap 222, discharge.Promptly, human body with static after the handle main body 112 that human body is gripped, metallic plate 173 and printed wiring 221 energisings, surpass the interelectrode breakdown voltage that constitutes microgap 222, therefore, between the electrode that constitutes microgap 222, discharge, arrive the frame ground FG terminal 181a of connector 181.
In step S6, judge whether frame ground FG is lower than the impedance of microgap 223.Usually, because frame ground FG is connected with the earth, so be the Low ESR lower than microgap 223, therefore, this action advances to step S7, and superpotential static passes through the glass door reinforcement plate 106 of formation frame ground FG to ground discharge.
Promptly, owing to pass through the interelectrode discharge of the microgap 222 of step S5, the low impedance circuit that formation is lower than resistance 193, so static can not switched on via 233 pairs of resistance 193 of through hole (being ended by resistance 193), and roughly all discharges to the glass door reinforcement plate 106 that forms frame ground FG via printed wiring 221, microgap 222, printed wiring 224, through hole 231 and frame ground FG terminal 181a.
Therefore, can produce the such static of electrostatic breakdown to testing circuit 191 blockings, the result can protect testing circuit 191.
In addition; owing to static is discharged to circuit ground, thus the electrostatic breakdown that static produces from the circuit ground adverse current also can be suppressed to the power supply 248 of for example back segment and control circuit 122 etc., therefore; not only testing circuit 191 can be protected, the circuit of Pinball machine 100 integral body can also be protected.
As Fig. 9, shown in Figure 10, utilization will constitute to becoming the fixing testing circuit substrate 201 of the position relation of idiostatic printed wiring 224 with frame ground FG from printed wiring 221, thereby the stray capacitance of distribution can be stopped at irreducible minimum (makes stray capacitance itself minimum, also make simultaneously the variation minimum of the stray capacitance of corresponding distribution position etc.), therefore, can be irreducible minimum with reduction (error of accuracy of detection) as the accuracy of detection of contact-making switch.
In step S7, discharge whole static on the glass door stiffener 106 of formation frame ground FG, then step S1 is returned in its processing.In addition, in step S5, frame ground FG advances to the action of step S8 than under the low situation of the impedance of microgap 223.
In step S8, human body (player) with static to microgap 223 energising, in step S9, discharge to circuit ground.
That is, frame ground FG is than under the low situation of microgap 223 impedances, because static surpasses the interelectrode breakdown voltage that constitutes microgap 223, so discharge between the electrode that constitutes microgap 223.At this moment, static discharges to circuit ground via printed wiring 225, through hole 221b and circuit ground terminal 181b.
For example, ground wire 132 is the situation of proper grounding not, and in step S6, frame ground FG is than the impedance height (usually, even ground wire 132 is earth-free, because the surface area of the glass door stiffener 106 of formation frame ground FG is big, so be Low ESR) of microgap 223.Therefore, frame ground FG is than under the high situation of the impedance of microgap 223, and static discharges to circuit ground via microgap 223.As a result, can protect testing circuit 191 at least.
In addition, in microgap 222,223, between electrode during release electrostatic, produce the phenomenon that spark disperses, but be located at the opposing face of the testing circuit substrate 201 that is formed with microgap 222,223 (microgap 222,223 is arranged at the back side portion of testing circuit substrate 201 shown in Figure 10 owing to constitute circuit beyond the microgap 222,223 of contact-making switch 163, it is facial that other structures are arranged at going up of testing circuit substrate 201 shown in Figure 9), so can suppress owing between the electrode of microgap 222,223, the disperse breakage etc. of other circuit of producing of spark.
In addition, microgap since on characteristic every generation any electrode of all losses that discharges, so microgap increase number of electrodes that can be high to discharge frequency, life-saving.
Usually, because imagination is to the frequency of utilization height of the employed microgap 222 of glass door reinforcement plate 106 discharges that constitutes frame ground FG than microgap 223, therefore, in the present embodiment, as shown in Figure 8, the number of electrodes of microgap 222: the number of electrodes of microgap 223=4: 4, but also can constitute with other number of electrodes, for example increase the number of electrodes of the high microgap of frequency of utilization 222, reduce the number of electrodes of the low microgap 223 of frequency of utilization.
Illustrated that above the interelectrode distance that constitutes microgap 222,223 is the situation of 0.2mm; but also the withstand voltage of circuit that can corresponding will protect changes, and with respect to the withstand voltage circuit of height, interelectrode distance increased; with respect to low withstand voltage circuit, interelectrode distance is reduced.
Below as shown in figure 11, the example that microswitch 161b is set at the leading portion of resistance 193 has been described, but microswitch 161b then also can play same effect if be disposed at the leading portion of control part 191, so for example as shown in figure 13, can be between capacitor 192 and testing circuit 191; Also can be between resistance 193 and the capacitor 192 as shown in figure 14.
In addition, microgap 223 is located between the circuit ground and frame ground FG of low potential side of power supply 248 in Figure 11, but be not limited thereto, for example, also can be that the hot side (ホ Star ト Side) that carries out power supply 248 carries out between the power supply terminal 181d and frame ground FG of the connector 181 that electric power supplies with.
More than, the situation of use three-wire type (3 Line formula) contact-making switch 163 (three-wire type testing circuit 191) has been described, but can be two-wire system (two-wire system: the two-wire that power supply is used with, circuit ground, the electric current of using by the control power supply flows, and forms human body contact detection result's signal output).
At this, specify the structure of the situation of using the contact-making switch 163 that two-wire system is arranged with reference to accompanying drawing 15.In addition, for the corresponding mechanism of structure of reference Figure 11 explanation, give same-sign, suitably omit its explanation.In the testing circuit 191 of the two-wire system of Figure 15, be with the difference of the testing circuit 191 of Figure 11, replace output circuit 246 that output circuit 301 is set, in addition, not only be provided with microgap 223, also be provided with microgap 223a, 223b.
Though output circuit 301 has and output circuit 246 identical functions basically, but based on comparative result from comparison circuit 245, by the output of control power circuit 241 itself, produce the square wave of assigned frequency, thereby output is as the testing result of testing circuit 191.
In addition, compare with the direct current three-wire type contact-making switch of Figure 11, the function of the microgap 223a of Figure 15 is equal, but inequality with microgap 223b insertion method about backup.Promptly, in the two-wire system contact-making switch 163 of Figure 15, because changing, the electric current of outside load resistance 247 becomes output signal, so arbitrary of load resistance 247 and two connecting lines (power supply with, circuit ground use) is connected also and plays a role basically, but from connection state, because the impedance variations of connecting line portion is so produce difference on the path of release electrostatic.
Therefore, in two-wire system contact-making switch 163, if microgap 223a, 223b insert arbitrary of two electric power supply lines, then via the path release electrostatic that does not link to each other with load resistance 247.In addition, the Zener diode 251 among Figure 15 is protection diodes of testing circuit 191, is the static countermeasure of further strengthening microgap 222,223a, 223b.
In addition, because microgap main body 161 only is to connect by the copper foil pattern on the testing circuit substrate 201, die owing to for example do not need to be equivalent to the distribution of the connecting line 12a of Fig. 1, can cut down the spuious electrostatic capacitance of distribution, so can suppress the deviation of the accuracy of detection of contact-making switch 163, simultaneously can cut down number of components, the cost of contact-making switch 163 is reduced.
The shape that contact-making switch 163 more than has been described is the situation of shape shown in Figure 7, but contact-making switch 163 is at the bottom surface sections 151 of relative resin-molded component 150 and metallic plate 173 abreast under the mode state of contact of subtend, if on the hole of metallic plate 173 173a of, 173b, connect metallicity screw 162a, 162b with bottom surface sections 151 subtends ground, screw thread is combined on the bottom surface sections 151, and then its shape can be other shape.
Figure 16～Figure 18 represents the example of situation of other shapes of contact-making switch 163.Figure 16 is the exploded view of the contact-making switch 163 of other shapes; Figure 17 is the stereoscopic figure of the contact-making switch 163 of other shapes; Figure 18 is the figure that the contact-making switch 163 of other shapes of explanation is installed on the state on the bottom surface sections 151.
As shown in figure 16, on resinous housing 271a, when groove 344a, the 344b of the roughly the same key shape of convex shape of metallic plate 273 insertions and metallic plate 273, the hole portion 341 of metallic plate 273 and the hole portion 342 of housing 271a are fixed as roughly same position.
At this moment, (it is different with the pattern of back side portion shown in Figure 10 to housing 271a, but the pattern of formation same circuits is the upward face of the testing circuit substrate 401 of Figure 16 by clamping testing circuit substrate 401 with cover 271b; Though with testing circuit substrate 201 shown in Figure 9 to go up facial pattern different, but the pattern that constitutes same circuits is the back side portion of the testing circuit substrate 401 of Figure 16), protuberance 301a, the 301b of housing 271a insert the 311a of hole portion, the 311b of microswitch main body 261, and the face that is provided with microswitch 261b of microswitch main body 261 is consistent with the end of housing 271a and fix.At this moment, ratchet 321a～321d of housing 271a is entrenched in the 311a～311d of hole portion of cover 271b respectively as shown in figure 17, thereby housing 271a is ended with cover 271b card, and is simultaneously that testing circuit substrate 401 is fixing.
Like this, under the situation of housing 271a and the state of cover 271b clamping testing circuit substrate 401,401 the printed wiring 221 of going up facial (constituting the pattern of the circuit identical with Figure 10 pattern) of Figure 16 contacts with metallic plate 273.As a result, same with the contact-making switch 163 of Fig. 7, metallic plate 273 is electrically connected with testing circuit substrate 401.
In addition, the back side direction of connector 281 from Figure 16 of testing circuit substrate 401 inserted the top among Figure 16, fixing protuberance terminal 261c～261f under the facial state that connects on the testing circuit substrate 401 of Figure 16, and with its electrical connection.In addition, about being connected of testing circuit substrate 201 and protuberance terminal 261c～261f, because identical with the connected mode of testing circuit substrate 201 with the microswitch main body 161 of Fig. 8, the Therefore, omited describes in detail.
In addition, testing circuit substrate 401 with the hole portion 342 of housing 271a same axle on, be provided with the recess 351 that constitutes by the diameter bigger than the diameter of hole portion 342.On cover 271b, with the hole portion 342 of housing 271a same axle on be provided with the recess 361 that the diameter bigger than the diameter of hole portion 342 constitutes.
According to such structure, the contact-making switch 163 of Figure 16～shown in Figure 180 as shown in figure 18, contact with the bottom surface sections 151 of the resin-molded component 150 of having implemented metal-plated with going up of Figure 17 is facial, and, microswitch operating portion 262a is under the state that becomes with the direction of stop button 153 subtends, top from Figure 18 in recess 361 and hole portion 342 connects metal screw-making 162 to the bottom direction, is incorporated into bottom surface sections 151 by screw thread and fixes.By so fixing, the part of exposing from housing 271a in the metallic plate 273 with bottom surface sections 151 state of contact under fixing, therefore, become the state that is electrically connected handle main body 112 and contact-making switch 163.
Therefore, there are contactless handle main body 112, resin-molded component 151 corresponding capacitance variations to transmit with human body to the testing circuit 191 of contact-making switch 163.
Like this, though the contact-making switch 163 of Figure 16～Figure 18 compare with the contact-making switch 163 of Fig. 5～Fig. 8 have in appearance more different, but metallic plate 173,273 contact-making surface is parallel with microswitch 161b, 262b direction of operating separately, and the direction that metal screw-making 162a, 162b, 162 direction of insertion and connector 182 insert contact-making switches 163 is with respect to being identical on the vertical this point of the contact-making surface of metallic plate 173,273.
As a result, the state that the player is roughly keeping gripping handle main body 112 is constant, and any at least finger of the hand by using gripping handle main body 112 can be operated stop button 153, can easily operate stop button 153 thus.
In addition, when contact-making switch 163 was installed on the handle unit 111, relatively resin-molded component 150 only was vertically to insert metal screw-making 162 and it is screwed togather fixing, just is fixed on the resin-molded component 150, simultaneously, also can be electrically connected with respect to metallic plate 173.In addition, the movable direction of stop button 153 can be consistent with the direction of operating of microswitch main body 161a.Metal screw-making 162 interconnects connector 281 and 182 by to resin-molded component 150 screw thread combinations.Thus, can easily carry out connector 281 and 182 be connected.In addition because contact-making switch 163 is integrally formed with microswitch main body 161, so only fixedly contact-making switch 163 just can be simultaneously fixing microswitch main body 161.
As a result, can cut down the working hour that contact-making switch 163 is installed on the operation on the handle unit 111, and can realize reliably.In addition, can make equipment miniaturization, simplification by reducing number of components.
About the contact-making switch 163 of Figure 16～Figure 18, only different in shape with the contact-making switch 163 of reference Fig. 5～Fig. 8 explanation, owing to carry out identical action, omit the explanation of action.
More than, as circuit protecting element, having illustrated to use has the example of microgap, but also can use the circuit protecting element outside it, for example, and discharger or variable resistor etc.
In addition, more than although understand from handle main body 112, metallic plate 173 and printed wiring 221 detect since the contact of human body produce and the earth between the example of changes in capacitance, still also printed wiring 221 can be constituted the terminal of connector 181.But, at this moment, because need be from the distribution of handle main body 112 or metallic plate 173, so must consider the stray capacitance that distribution produces.In addition, also can be the structure (can with the part of handle main body 112) that directly constitutes handle main body 112 by printed wiring 221 as the copper foil pattern that constitutes printed wiring 221.
In addition, in this manual, in the step of describe in detail handling, the processing of carrying out with time series along the order of record obviously may not be that time series ground is handled, and also can be side by side or the processing of carrying out respectively.
