Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condition change switch for a microprocessor used to change the operating conditions of the microprocessor.

[0002]

2. Description of the Related Art Conventionally, a microprocessor can achieve the same function as any hardware-configured control circuit in a software manner by a program, so that it is a main control circuit for various electronic devices from home electric appliances to industrial products. It is used as a component. Further, it is possible to achieve different functions in a device incorporating a microprocessor simply by modifying the above program, and it is possible to improve the device development efficiency by eliminating complicated and costly hardware changes. Moreover, the programs created in this way can be stored as a library,
It is also effective in shortening the device development period for the next model, which has only slightly different control specifications.

In order to further improve the efficiency of control circuit development using such a microprocessor, there is a switch for changing the operating condition of the microprocessor from outside, a so-called condition changing switch. As this type of condition changing switch, a dip switch, which is a simple two-contact switch, is generally known. Normally, a DIP switch connects one contact to a power supply line and the other contact to a ground line, and operates the switch to change the potential of a connection point connected to a predetermined input port of a microprocessor to a power supply potential or a ground potential. Used as a potential.
Therefore, the potential of a predetermined input port connected to this DIP switch is confirmed, and a program in which the branching condition, variable selection, control specifications, etc. are changed according to the potential is stored in advance in the microprocessor. Then,
It becomes possible to change the operating conditions of the microprocessor simply by operating the switches, which dramatically improves the program development efficiency.

[0004]

However, the conventional condition change switch has the following problems. The condition change switch such as a DIP switch has a function of merely selecting any one of the operating conditions of the microprocessor prepared by the program, and a desired switch operating state (on or off). Once is determined, the switch function is no longer needed unless the setting change is repeated.

Therefore, the conventional condition change switch has been developed with the goal of providing a small size and low cost by limiting the operability and durability of the switch to the minimum. However, no matter how small and cheap the goal is to design a condition-changing switch, in order to guarantee the minimum function as a condition-changing switch, the size that is indispensable for the switch operation and the reliability against multiple times of switch operations are required. Therefore, there is a limit to the reduction of occupied volume and cost. On the other hand, the control circuit mainly composed of the microprocessor is highly integrated with the microprocessor.
Due to remarkable technological development such as surface mounting of peripheral electric elements, it is becoming smaller and more sophisticated, and even more occupied for condition change switches that become unnecessarily long after the switch operating state is determined once. Reduction in volume and cost is desired.

It is known that a conductor called a jumper wire is wired between specific land patterns to be used for setting conditions similar to those of a DIP switch, but in the case of a jumper wire, soldering is at least 2 times. There is a problem that the workability is poor, because it requires some parts, and further, when changing the condition setting, it is necessary to remove the jumper wire.

The present invention solves these problems, provides a condition change switch which occupies a printed circuit board to a minimum, has an inexpensive circuit configuration, and can surely change the operating condition of the microprocessor. It was made for the purpose of having the following composition.

[0008]

A condition changing switch for a microprocessor according to the present invention comprises an input section made of a good conductor, one end of which is electrically connected to an input port of the microprocessor, and the other end of which is a soldering section. A connection switch section that is opposed to the soldering section of the input section through an insulating section having a predetermined width determined according to the viscosity of the solder and that is composed of a plurality of soldering sections that are arranged so as to be insulated from each other; The gist is that each of the plurality of soldering parts of the connection switch part is provided with a condition setting part for applying mutually different potentials.

[0009]

In the condition changing switch of the microprocessor of the present invention configured as described above, the soldering portion of the input portion and the plurality of soldering portions of the connection switch portion have a predetermined width determined according to the viscosity of the solder. Are facing each other. Therefore,
If the predetermined width that is determined according to the viscosity of this solder is designed to be the width that causes a solder bridge, the soldering part of the opposite input part can be connected to the soldering part of the connecting switch part just by performing the soldering work. After the electrical conduction is completed, the electric potential applied to the arbitrary soldering section by the condition setting section can be applied to a predetermined input port of the microprocessor.

Further, when a printed circuit board is produced by using an automatic soldering furnace, if the predetermined width determined according to the viscosity of the solder is designed to be slightly larger than the width at which the solder bridge is generated, the automatic soldering is performed. In the process of producing a printed circuit board using a soldering furnace, a sufficient amount of solder is deposited on all soldering parts to complete the printed circuit board. Therefore, place a connection piece (may be solder) made of a good conductor between any soldered part of the connection switch part and the soldered part of the input part, and heat both connection parts with a soldering iron etc. The electrical conduction of the section is completed, and a desired potential can be input to a predetermined input port of the microprocessor as described above.

It should be noted that, if a default setting unit is provided in advance for conducting the soldering part of the input part in advance to the most frequently used potential among a plurality of kinds of potentials that may be applied to the predetermined input port of the microprocessor, the default value is provided. The soldering work may be performed only when the potential applied to the predetermined input port by the setting unit needs to be changed. The default setting portion can be easily realized by, for example, setting the width of the insulating portion on the conducting side to a dimension that causes a solder bridge, and setting the width on the non-conducting side to a width that does not cause a solder bridge. . In this case, setting the default state can be completed simply by passing the printed circuit board through the solder bath. Since it is possible to set the default value by soldering, there is an advantage that the default value can be easily changed as compared with the case where the default value is set by the pattern.

Embodiments In order to further clarify the structure and operation of the present invention described above, an embodiment in which the condition changing switch of the present invention is applied to a pachinko ball launching device will be described below. First, a pachinko machine 1 equipped with a pachinko ball launching device 30 according to an embodiment of the present invention will be described with reference to the front view of FIG.

As shown in FIG. 1, a metal frame 3 is provided around an opening of a front frame 2 formed in a frame shape of a pachinko machine 1, and the metal frame 3 has a glass door frame 4 and a front plate 5. Is openable and closable. Behind the glass door frame 4, a game board 6 detachably attached to a game board fixing frame (not shown) fixed to the back surface of the front frame 2 is arranged. On the front surface of the game board 6, a guide rail 8 for guiding a pachinko ball is planted in a substantially circular shape, and a game area 9 is formed in an area surrounded by the guide rail 8.

A variable winning a prize device 10 is provided substantially in the center of the game area 9. The variable winning device 10 has a pair of open / close blades 11a and 11b, and these open / close blades 11a and 11b are kept under a constant condition for a predetermined time (for example, 30
Seconds) or a fixed number (for example, 10)
The jackpot operation is performed in which the winning state is released until a prize is won, and such an open state is repeated several times (for example, 16 times) to generate a large number of winning balls in a short time. Further, a jackpot lamp 1a is provided on the back surface of the variable winning device 10, and by blinking the lamp 1a during the jackpot operation,
It is displayed to the player that the jackpot operation different from the normal game rule is being performed.

A variable display 12 composed of a plurality of digital displays is formed below the variable winning device 10, and its display mode is a pachinko ball at starting winning openings 13a to 13c provided below the game area 9. Starts changing when a prize is won, and stops when the stop switch 14 provided on the front frame 2 is pressed or when a predetermined time (for example, 5 seconds) elapses. Then, the display mode of the variable display 12 at the time of this stop is a predetermined display mode (for example,
When the numbers are the same (three digits), the variable winning device 10 is designed to execute a jackpot operation.

Further, in the game area 9, general prize holes 15a to 15d are provided in addition to the variable prize device 10 and the starting prize holes 13a to 13c, and any of the prize devices or prize holes described above is provided. An out port 16 is formed through which a pachinko ball that has not won a prize is guided.

On the surface of the front plate 5, the prize balls (pachinko balls) paid out by the generation of the winning balls are preferentially stored,
Moreover, the upper plate 18 for guiding the pachinko ball to the firing position is attached. The front frame 2 has two lamps 1b,
1c is embedded, and a state in which the player has started playing a game on the pachinko machine 1 or a game state in which an illegal act has been performed is explicitly displayed.

In addition to this, below the front frame 2, a projecting strength adjusting handle 20 operated by the player is fixed in a protruding manner. The firing strength adjusting handle 20 is rotatably provided with an adjusting lever X for adjusting the elastic force of a pachinko ball. The adjusting lever X is composed of a metal annular member, and is used for pachinko ball launching device 30 as will be described later.
It is also used as a part of the circuit element that constitutes the parallel resonance circuit 345. Further, the firing intensity adjusting handle 20 is provided with a single shot switch 22. This one-shot switch 22
When this is operated, the solenoid clutch 4 described later
8 is operated to interrupt the transmission of the rotation of the pachinko ball firing motor to interrupt the pachinko ball firing. The same function can be realized by adopting a configuration in which the motor is stopped.

Below the front frame 2 and to the side of the firing strength adjusting handle 20, there is attached a lower plate 23 for storing a prize ball which is further paid out when the upper plate 18 is full.

Next, the structure of the pachinko ball launching device 30 arranged on the back surface of the pachinko machine 1 at the position where the firing strength adjusting handle 20 is attached will be described with reference to FIG. As shown in the figure, a firing motor 32 including a stepping motor and a ball firing mechanism 40 driven by the rotational force of the firing motor 32 are disposed on the rear surface of the mounting position of the firing strength adjusting handle 20.

The ball firing mechanism 40 includes a coil spring 42, a ball striking rod 44 urged by the coil spring 42, and a locking lever 46 which causes the ball striking rod 44 to perform a ball striking operation of a pachinko ball by a cam mechanism (not shown). It is well known.
When the firing motor 32 rotates, the locking lever 46 first pulls the ball striking rod 44 against the coil spring 42 in the leftward direction by rotation of a cam mechanism (not shown). Along with this, the coil spring 42 gradually expands. When the firing motor 32 rotates by a predetermined angle, the cam mechanism and the locking lever 46
The ball hitting rod 44 tries to return to its original position at once by the force of the coil spring 42, and at that time, hits the pachinko ball. The strength with which the batting rod 44 hits a pachinko ball is determined by the extension state of the coil spring 42 when the batting rod 44 returns. Since this position is determined by the amount of rotation of the adjusting lever X of the firing strength adjusting handle 20, the pachinko ball is eventually fired with a strength corresponding to the position of the adjusting lever X. When the one-shot switch 22 is operated, the solenoid clutch is activated to interrupt the transmission of the rotation of the firing motor 32. Therefore, by appropriately operating the one-shot switch 22, it is possible to use the pachinko ball to fire one-shot. Is.

When the single-shot switch 22 is not operated, the pachinko balls are fired once per one revolution of the firing motor 32. The strength with which a pachinko ball is fired is proportional to the amount of rotation of the adjustment lever X. Also, single-shot switch 2
By manipulating 2, the pachinko ball firing strength can be kept the same, and the pachinko ball firing can be either sporadic or sporadic.

The rotation speed control of the firing motor 32, which determines the firing state of the pachinko ball firing described above, is executed by the control circuit 34 arranged in the vicinity of the firing motor 32. An electric circuit of the pachinko machine 1 centering on the pachinko ball launching device 30 including the control circuit 34, the launch motor 32, and the single-shot switch 22 is shown in the block diagram of FIG.

As shown in the figure, the control circuit 34 is mainly composed of a one-chip microcomputer (hereinafter referred to as MPU) 341 in which peripheral circuits are contained in one chip. That is, the MPU 341 has a built-in CPU that serves as a core, a ROM that stores various programs to be described later, and a timer system that measures a real time from a clock signal of the clock circuit 342 and that temporarily stores information.
It incorporates an external circuit of the AM and MPU 341 and an input / output port that supports input / output of various information. Also, MP
U341 is a port PU that can directly input analog signals.
With a predetermined resolution (here, 8 bits), an analog signal can be directly input while being converted into a digital signal.

The driver circuit 343 has a monitor lamp L1.
Through L3, the solenoid clutch 48, and the firing motor 32 are driven based on the control signal from the MPU 341. The control signals from the output ports PO1 to PO8 of the MPU 341 are input and the corresponding 8 Generates a bit signal. Of these, the 4-bit output signal of the driver circuit 343 is output to the connector CN1 via the current limiting resistors R1 to R4. The power supply voltage Vc (28 [V]) is also output to the connector CN1, and the monitor lamps L1 to L3 and the solenoid clutch 4 which receive this via the connector CN1.
8 turns on or operates when the 4-bit output signal of the driver circuit 343 becomes low level.

The monitor lamps L1 to L3 are lamps that indicate the operation mode of the control circuit 34, and are used to display various information such as the type of the control circuit 34 and the type of error when an error occurs.

On the other hand, the other 4-bit output signal of the driver circuit 343 is directly used as an excitation signal for the firing motor 32. The firing motor 32 receives the excitation signal and the power supply voltage Vc via the connector CN2. MP
The U 341 can control the rotation of the firing motor 32 by controlling this excitation signal. The Zener diode ZD1 connected between the driver circuit 343 and the power supply Vc is for absorbing a surge caused by the L load.

The four input ports PI1 to PI1 of the MPU 341
The PI 4 is used to change the operating condition of the MPU 341. As will be described later in detail, the MPU 3 of this embodiment
The control program burned in the ROM of 41 detects the input states of the input ports PI1 to PI4 and changes the branch condition, the control target, the controlled variable, the variable to be selected, the control timing, and other operating conditions according to the result. Pre-designed to

FIG. 4 is an enlarged explanatory view of a detailed pattern configuration of the condition changing switch 344 connected to the input ports PI1 to PI4. As shown in the figure, the condition change switch 344 has two soldering portions (hatched portions in the figure).
And connection points S1 to S4 respectively having this
S4 to S4, the connection points SA and SB are formed of a pair of four soldering portions arranged in proximity to the respective soldering portions. Input port PI1 to MPU341
PI4 is connected to each of connection points S1 to S4. Further, one connection point SA facing the connection points S1 to S4
Is connected to the power supply Vcc (5 [V]), and the other connection point S
B is electrically connected to the pattern on the back surface of the printed board through the connection hole SH and is connected to the ground.

In this embodiment, the connection points SA and SB are arranged in the same direction with respect to the common connection points S1 to S4.
The connection points SA and SB may be arranged symmetrically on both sides of the common connection point S1 to S4. In this case, the right side or the left side is “0” with respect to the common connection points S1 to S4.
Since it corresponds to the signal level of "1", there is an advantage that the current set value can be read at a glance.

Since one of the soldering portions of the connection points S1 to S4 is connected to the soldering portion of the opposing connection point SB by the pattern of the minimum line width, the potential of the input ports PI1 to PI4 of the MPU 341 is changed. Becomes the power supply potential Vcc as a default value.

The other input port PIS of the MPU 341 is a port for detecting the operation status of the one-shot switch 22, and is connected to the one-shot switch 22 via a chattering elimination integrating circuit composed of resistors R5 and R6 and a capacitor C1, and a connector CN3. To be done. Since this signal line is pulled up by the resistor R7, an "H" level signal is input to the input port PIS unless the one-shot switch 22 is pressed. On the other hand, when the one-shot switch 22 is pressed, the signal to the input port PIS changes to the “L” level, and the operation state of the one-shot switch 22 is determined. In addition,
The diode D1 is provided for protection.

The rectangular wave output from the output port PS of the MPU 341 has a time constant τ (= R due to the integral action of the resistor R10 (resistance value R) and the capacitor C2 (capacitance value C).
C) Capacitor C3 that is annealed only and cuts the direct current component
Is input to the parallel resonance circuit 345 in the form of an approximately sinusoidal AC waveform. Here, the parallel resonance circuit 345 is a parallel type resonance circuit composed of the coil L and the capacitance component of the adjustment lever X connected via the capacitor C4 and the resistor R11, and the adjustment lever X at a separated position. In order to facilitate the connection with the connector CN4, the connector CN4 is used. The circuit constants of the constituent elements of the parallel resonance circuit 345 including the adjustment lever X are determined so that the sharpest resonance state is exhibited when the player is not in contact with the adjustment lever X.

The output signal of the output port PS is controlled by the MPU 341 so as to be a discrete AC power source of a plurality of frequencies with respect to the parallel resonant circuit 345. The actual condition will be described later in detail.

The parallel resonant circuit 345 is applied with discrete AC signals of a plurality of frequencies, and the parallel resonant circuit 345 in this state is applied.
MPU34 to detect and store the impedance value of
One input port PU is used. Therefore, the terminal voltage of the parallel resonant circuit 345 is AC-coupled by the capacitor C5, half-wave rectified by the diode D2, smoothed by the integrating circuit by the resistor R12 and the capacitor C6, and input to the input port PU. To be done.
Therefore, a voltage signal proportional to the magnitude of resonance of the parallel resonance circuit 345 is input to the input port PU. The input port PU is a port that can input an analog signal. A resistor R13 is provided between the signal line to the input port PU and the ground line for discharging the electric charge charged in the capacitor C6.

In addition to this, the control circuit 34 includes an MPU 341.
Resistors R20, R21 for delaying the reset timing of the power supply Vcc by a predetermined time from the rise time of the power supply Vcc,
The integrating circuit 346 including the capacitors C20 and C21 and the diode D10 is formed, and the RES of the MPU 341 is
Connected to ET port. In addition, the power sources Vc and Vcc
Is generated from an AC power supply (AC24 [V]), a power supply circuit 34 including a diode full-wave rectification circuit, a smoothing circuit, a voltage stabilizing circuit using a Zener diode, and the like.
7 are formed.

Next, an interrupt program which is executed by the MPU 341 of the present embodiment configured as described above and is a process for scanning the output signal from the output port PS in a predetermined frequency band (see FIG. 5) will be described. To do.

The interrupt program is a program executed when an interrupt signal is input to the interrupt request port IRQ of the MPU 341 by interrupting the processing of the main program executed by the MPU 341 until then. In this embodiment, as shown in FIG. 3, the output port VRE is used as an interrupt signal to the interrupt request port IRQ.
The signal from the FE is used. Therefore, first, the function of the output port VREFE will be described with reference to the flowchart of the initial processing program of FIG.

The initial processing program of FIG. 6 is MPU34.
This is a program that is executed only once when the power is turned on before the main program is processed, and executes the hard check and software-like initial condition setting necessary to maintain the execution conditions of various programs described later.

When the initial processing program is started, the MPU
The 341 first checks the hardware configuration including the built-in RAM and the connection condition of various connectors CN, etc., and if any defect is found in any of them, a hardware check process such as notifying the hole management computer (step) Four
00) is executed. Next, the data of the input ports PI1 to PI4 is read (step 402), and the values to be set in the variable B and the variable y are determined based on the read data.

That is, in the following step 404, the variable B
As a value of, when both input data from the input ports PI1 and PI2 are at the ground potential (“0”), the value B1 is set, when PI1 = Vcc, PI2 = 0, the value B2 is set, and PI1 = 0, PI2 = Value B when Vcc
3, the value B4 is set when PI1 = Vcc and PI2 = Vcc. In the next step 406, the input ports PI3 and PI4 are both set to "0" as the value of the variable y.
, The value y1 is set, when PI3 = Vcc, PI4 = 0, the value y2 is set, when PI3 = 0, PI4 = Vcc, the value y3 is set, and when PI3 = Vcc, PI4 = Vcc, the value y4 is set. .

Incidentally, the input ports PI1 to PI of the present embodiment.
4 is the connection points S1 to S of the condition changing switch 344 described above.
4 and the condition change switch 344.
The connection status of remains the default value. Therefore, by the processing of steps 402 to 406, the variable B becomes the value B4,
The variable y is set to the value y4. This variables B and y
Is used to define the lower and upper limits of the frequency scan. .

Subsequently, the MPU 341 sets the variable B (value B4 by default) in the compare register of the built-in timer system (step 408). The timer system is composed mainly of various timers that run completely independently of the operation of the CPU, which is the core of the MPU 341. When any value is set in the compare register, the set value is set. And when the measured value of the predetermined timer matches, a signal is output from the output port VREFE of the MPU 341. Therefore, MPU34
If the above variable B is set in the compare register of this timer system at the time of initial processing at the time of power-on of 1,
A signal is output from the output port VREFE each time the measured value of the predetermined timer matches the variable B set in the compare register, that is, at each interval Tb corresponding to the variable B. The value set in the compare register is hereinafter referred to as set value CX.

Since the output port VREFE which outputs a signal at each interval Tb in this way is connected to the interrupt request port IRQ of the MPU 341, the MPU 34
1 repeatedly interrupts the main program every interval Tb to execute interrupt processing (interrupt program described later). After setting the values of the variables B and y in this way and setting the variable B in the compare register, the flag F is set to the value 1 and the output port PS is set to the low level "L" (step 410). After the above processing, this initial processing program ends.

After the initialization process, the MPU 341 executes a main routine (not shown), but the main routine executes processes of excitation timing for each phase of the firing motor 32, and is substantially different from the main routine. It's just waiting for an interrupt. The interrupt process activated at each interval Tb is shown in the flowchart of FIG. When this interrupt processing routine is activated, the MPU 341 determines whether or not the output state of the output port PS is low level "L" (step 500), and if the output is already "L", it raises it. Processing for changing to level "H" is performed (step 502). Immediately after the initialization process, since the output port PS is set to the low level "L", these processes are performed.

On the other hand, the output state of the output port PS is "H".
If so, this is changed to "L" (step 504).
After that, the voltage data applied to the terminal PU is stored together with the set value CX of the compare register (step 506). This process is performed by the voltage data ZD of the terminal PU obtained by executing the contact determination routine this time.
n is stored in association with the set value CX of the compare register. Further, the process of updating the maximum value of the terminal voltage (steps 508 to 510) is performed, and this process compares the terminal voltage data ZDn of this time and the terminal voltage data ZDn-1 stored by the previous execution of this routine. The relations are compared, and when the current terminal voltage data ZDn exceeds the previous data, the terminal voltage data ZDn is set to the variable Z.
It is stored as max. After performing the processing of step 510, this routine is once ended.

On the other hand, after the above-mentioned processing of step 502, the state of the flag F indicating the frequency increase / decrease instruction is confirmed (step 530), and if the flag F is "1", the MPU.
The set value CX of the compare register built in 341 is incremented by a predetermined value (step 540), and if the flag F is "0", the set value CX is decremented by a predetermined value (step 550).

Since the value of the compare register determines the interval Tb until the next interrupt is input, the output of the output port PS changes from "H" by the increment or decrement processing of the set value CX of this compare register. The period during which "L" or "L" changes to "H" gradually increases or decreases. In other words, the cycle T of the rectangular wave output from the output port PS is gradually changed to longer or shorter by this process, and the flag F is used as a switch for changing the increase or decrease of the cycle T. The above-described processing (steps 530 to 550) is performed only immediately after switching the output port PS from the low level "L" to the high level "H".
Since it is not performed immediately after switching from "H" to "L", the duty of the AC signal applied to the parallel resonant circuit 345 is maintained at 50%.

When the set value CX of the compare register is incremented, it is judged whether or not the value is equal to or more than the upper limit value y (step 560). If it is equal to or more than the upper limit value y, the cycle is not increased. Assuming that the limit has been reached, the flag F is set to "0" (step 570), and the process proceeds to the contact determination process (step 600). Similarly, when the set value CX of the compare register is decremented, it is determined whether or not the value is equal to or less than the lower limit value B (step 580).
Is set to "1" (step 590), and the process proceeds to the contact determination process (step 600). If the set value CX of the compare register is within the range of the lower limit value to the upper limit value, this routine is terminated without performing the contact determination process.

Next, the details of the contact determination process will be described with reference to FIG. In this process, first, a plurality (m) of terminal voltage data ZD1 and ZD stored so far are stored.
2, ZD3, ..., ZDm and the variable Zma which is the maximum value thereof
The magnitude relationship with the value of x times x is judged (step 62).
0). Then, it is determined whether or not the number of pieces of terminal voltage data ZD larger than Zmax / 2 is equal to or smaller than a predetermined value DB (step 622).

Such a judgment process is performed by the parallel resonance circuit 345.
It means to judge the sharpness Q of the resonance. Figure 9
6 is a graph showing that the sharpness Q of resonance can be seen from the change in the terminal voltage data ZD with respect to frequency. In this figure, the horizontal axis represents the set value CX of the compare register, and the value becomes smaller toward the right side. Since this set value CX is proportional to 1 / frequency, when converted to frequency, the frequency becomes higher toward the right side.

The parallel resonance circuit 345 itself designed to exhibit the sharpest resonance state when the player is not in contact with the adjusting lever X has the maximum impedance at the resonance frequency as designed, and a large terminal voltage. Data ZD (ZD4 in FIG. 9) is obtained, and the impedance value sharply decreases at a frequency slightly deviated from the resonance frequency. However, when the player is in contact with the adjustment lever X, the resonance state of the parallel resonance circuit 345 is largely collapsed from the time of design, and the maximum impedance Zmax at the resonance frequency.
Not only becomes smaller, but the impedance change at a frequency slightly deviated from the resonance frequency also becomes dull. Therefore,
The number of the terminal voltage data ZD exceeding Zmax / 2 is extremely small when the player is in the non-contact state with the adjusting lever X, and conversely is extremely large when the player is in the contact state. Figure 9
According to the example shown in (1), the terminal voltage data ZD exceeding Zmax / 2 is "3" in the non-contact state and "6" in the contact state.

Therefore, when it is determined to be "true" in step 622, that is, when the number of terminal voltage data ZD of Zmax / 2 or more is less than the predetermined value DB, contact / contact
The flag G for non-contact judgment is reset to "0" to confirm the non-contact state (step 624), and the terminal voltage data ZD and the variable Zm so far are used for the next contact judgment processing.
The ax is erased (step 626), and this routine ends. On the other hand, when it is determined to be "false" in step 622, the flag G is set to "1" to check the contact state (step 628), and the terminal voltage data and the like are similarly erased (step 630). ) End this routine.

As described above, the AC signal whose frequency is scanned in the predetermined frequency band is obtained by gradually increasing / decreasing the set value of the compare register, and this is applied as the AC power source of the parallel resonant circuit 345. Therefore, by inputting the terminal voltage of the parallel resonant circuit 345 over the frequency band from the input port PU, the parallel resonant circuit 345
It is possible to accurately determine the resonance state of, that is, the contact / non-contact state with the adjusting lever X. The contact / non-contact state with the adjustment lever X thus determined is determined by another routine of the main program, for example, the firing motor 32.
It is needless to say that the pachinko machine 1 is used for various controls such as a motor drive routine for controlling the rotation of the pachinko machine 1.

According to the pachinko ball launching device 30 of the present embodiment having the above-described configuration, the following effects can be obtained. The pachinko ball launching device 30 determines the contact / non-contact of the player by the resonance sharpness sphere of the resonance circuit 345, and the frequency scan band at that time is read in the initial process executed when the power is turned on. Condition change switch 344
Set according to the state of. That is, four kinds of values are selected from the lower limit value B and the upper limit value y of the set value of the compare register. Therefore, as is clear from the waveform explanatory diagram of the output port PS in FIG. 5, the variable range of the interval Tb (set value CX), that is, the minimum value of the scan frequency (corresponding to the upper limit value y of the set value) to the scan frequency. Up to the maximum value (corresponding to the lower limit value B of the set value) can be selected, and the optimum scan frequency for detecting the resonance state of the parallel resonance circuit 345 can be determined by the condition change switch 344. it can.

The scan frequency bands selectable by the condition changing switch 344 are shown in the lower column of FIG. As shown in the figure, by arbitrarily determining the connection state of the condition changing switch 344, the scan frequency band can be arbitrarily selected from four types of highest frequencies, that is, four types of highest frequencies, in total. it can. Therefore, MPU34
The resonance state when the player is in contact with the adjustment lever X (symbol A in the drawing) and the resonance state when the player is not in contact (symbol B in the drawing) are covered without changing the program of 1. The frequency band can be selected by the connection state of the condition change switch 344. Moreover, the condition change switch 34
4, as shown in FIG. 4, since the connection points S1 to S4 are connected to the power supply line as default values so that the frequency band is optimum for a specific configuration, You can save the trouble of changing the connection status.

However, the judgment of contact / non-contact is considerably influenced by the configuration of the pachinko machine 1, the place where the pachinko machine 1 is installed, the environment, etc. Therefore, it may be desirable to change the frequency band for judging the resonance state. It is possible. In such a case, the connection state of the connection points S1 to S4 is changed, but the purpose can be achieved only by bringing the soldering portions arranged extremely close to each other into a conductive state, and therefore, it is possible to deal with it by a simple work. can do.

Further, in this embodiment, in order to detect the game state in which the player is holding the adjusting lever X, the present embodiment has a simple circuit structure consisting of the inductance of the coil L and the capacitance of the adjusting lever X. Parallel resonance circuit 34
5 is adopted. Therefore, the pachinko ball launching device 30
Since the constituent circuit elements as a whole are largely omitted, the structure can be made small and inexpensive. Further, unlike the conventional oscillation circuit, no circuit adjustment such as amplification factor and feedback phase is required, which simplifies the manufacturing process and enables mass production of stable quality products.

Further, in the present embodiment, whether or not the player is holding the adjusting lever X is determined by the terminal voltage data of many parallel resonant circuits 345 over a predetermined frequency band. Therefore, as compared with the conventional binary determination as to whether or not the oscillation circuit is oscillating, the accuracy of the determination is significantly improved.

In addition, the pachinko ball launching device 3 of this embodiment
0 is the MPU341 as a power source for firing a pachinko ball
The firing motor 32 that is a stepping motor that can be directly driven by is used. Therefore, as compared with the conventional large-sized AC motor that requires a special electric circuit for starting, the pachinko ball launching device 30 does not require the AC power line to be routed and can be made compact. Become.

In this way, the pachinko ball launching device 3 of this embodiment is used.
0 can be configured extremely easily and in a small size, and the firing motor 32 and the control circuit 34 can be integrally configured without separately configuring them as shown in FIG. Moreover, in the case where the control circuit 34 and the firing motor 32 are integrally configured in this manner, since the entire occupied volume thereof is extremely small, it is possible to incorporate all of them in the firing strength adjusting handle 20. It is also possible to dispose other constituent devices, for example, a card reader of a card-type pachinko ball lending machine, on the rear surface portion of the firing intensity adjusting handle 20 of 1.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the scope of the present invention. is there. For example, in the present embodiment, the connection state of the condition change switch 344 is judged by the binary value of the ground potential or the power supply potential (Vcc), but as shown in FIG. 10, the analog input port of the MPU 341 is used to make one The program execution condition may be changed by inputting three or more potentials at the input port. Further, in the present embodiment, the holding state of the adjusting lever X is detected by the parallel resonance circuit 345, but instead of this, a series resonance circuit may be adopted.

Further, the power supply frequency of the parallel resonance circuit 345 is gradually increased and gradually decreased by incrementing and decrementing the set value of the compare register. However, it is sufficient if the frequency can be scanned in a predetermined frequency band, and another method is used. The frequency may be gradually increased / decreased, or only one of the frequency may be gradually increased or decreased.
