Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine, and more particularly to a technique for prohibiting removal of a cover covering a board or a harness (wiring) built in the gaming machine in a power-on state.

  Pachinko machines such as pachinko machines and slot machines that are installed and used in game halls such as pachinko parlors are given a certain value to game media such as pachinko balls and medals, and the game media acquired by playing games It can be exchanged for various prizes. The gaming machine is provided with various drive devices such as a lamp device and a sound generation device that are operated based on the supply of the game medium, and a control circuit device corresponding to control these drive devices inside the housing. Therefore, when the player plays a game, the game is filled with interest by appropriately operating them. Further, in recent years, a variable symbol display device such as a reel display device or a liquid crystal image display device that can display predetermined identification information (symbol) in a variable manner is built in and stopped after changing the identification information when a predetermined condition is satisfied. The mainstream is to operate the variable symbol display device so that it can be displayed. These devices are controlled by a control circuit device.

  A control circuit device disposed in a recent gaming machine is generally one in which a CPU (central processing unit) provided on a board performs electronic control according to a control program. The control program is stored as data in an IC chip mounted on a substrate such as a mask ROM (read only memory), and the CPU sequentially reads and executes the control program data from the IC chip according to the gaming state.

To open the winning opening, to open the open door of the attacker 30e, etc.). That is, the accessory device controller 55 turns on the effect display lamp of the variable display device (center accessory) 30a based on the control signal from the controller 40, or the image related to the effect on the LCD (liquid crystal display device). Is displayed, the movable piece of the start chuck 30d is opened, and the movable door of the attacker 30e is opened.

  In other words, the accessory device control unit 56 performs an electronic pass / fail lottery based on the establishment of a predetermined condition in the winning determination unit 40a provided in the control unit 40 (for example, winning of a game ball to the start winning device 30d). It is also a display control device that performs stop display after variably displaying the identification display information (displayed on the LCD of the variable display device (center accessory) 30a) according to the result. Further, the accessory device control unit 56 performs the identification lighting according to the result of the electronic winning / losing lottery based on the establishment of a predetermined condition in the winning determination unit 40a (for example, the passage of a game ball to a predetermined passing port). It is also a display control device that performs stop display after variably displaying information (lighted and displayed on the effect display lamp of the variable display device (center accessory) 30a).

  The LCD (not shown) of the variable display device (center accessory) 30a is a device that variably displays a specific symbol related to the big hit state and also displays a background image and various characters in an animated manner. When it is detected that the game ball has passed through the start chucker (start winning device) 30d, the displayed symbol fluctuates for a predetermined time, and the lottery is drawn when the game ball start chucker (start winning device) 30d passes. The stop symbol determined by the random number for lottery is displayed on the LCD and stopped. The attacker 30e includes an opening / closing plate that can be opened forward.

An acoustic control unit 46 generates sound effects / sounds through a speaker 52b provided in the gaming board 10 or the gaming machine casing.

  The winning devices 30b to 30e in which game balls are provided in the game area are provided with ball passage detectors (for example, switches) 20b to 20e, respectively, so that the passage of the game ball can be detected. When the position of any of the winning devices 30b to 30e is passed, the ball passage detectors 20b to 20e detect this, and the winning determination unit 40a performs a predetermined lottery / determination process. For example, when the ball passage detector 20b detects a game ball that has passed through the through chucker (winning chucker) 30b, a predetermined lottery is performed, and when winning, the start chucker (starting winning device) 30d is released for a predetermined time. That is, a pair of movable pieces provided opposite to each other on both the left and right sides of the start chucker (start winning device) 30d are opened outward. At the same time, the effect of winning is displayed on the variable display device (center accessory) 30a. Then, when it is detected that the game ball has passed the start chucker (starting winning device) 30d, a predetermined lottery is performed, and when winning, the big winning device of the attacker 30e is released.

  The control unit 40 includes a CPU, a read only memory (ROM), a read / write memory (RWM), and an input / output unit (I / O). The CPU performs predetermined processing according to a program stored in advance in the ROM. Actually, the winning determination unit 40a is realized by the CPU executing a program.

  FIG. 5 is a view (rear view) of the gaming machine according to the embodiment of the present invention as viewed from the back. FIG. 6A is a right side view of the gaming machine. FIG. 6B is a cross-sectional view taken along the line AA in FIG. Note that a part (upper part) of FIG. 6A shows a state in which the gaming machine is cut out along the line BB in FIG. In these drawings, the display of the outer frame 50 is omitted.

  In these drawings, C is a cover that covers the control unit 40, the sub-control unit 40b, and the payout control unit 42 (this is an example, and what the cover covers is not limited to this). SL is a solenoid that constitutes a lock mechanism. PWS is a power switch of the gaming machine. The power switch PWS is for turning on and off a power supply unit (a gaming machine power supply device PS1 described later). Although not shown, the power supply unit is provided on the lower back side of the main body member 51, for example. In FIG. 2, the display of the cover C is omitted.

  The cover C covers the main components (boards) of the gaming machine as described above, and covers a harness connected to these, although not shown. As long as it is covered with the cover C, removal of each board and insertion / extraction of a harness cannot be performed.

  The cover C is provided with a claw C1 for hooking it on the main body member 51 in order to fix one side of the cover C so as to be rotatable. The claw C1 functions like a hinge while it is hooked. On the opposite side of the claw C1, an opening (through hole) C2 into which the action portion SL1 of the solenoid SL which is a locking mechanism is fitted is provided.

  The solenoid (Solenoid) is an actuator that drives an iron core by electromagnetic force, and includes a solenoid coil SL2 that is an electromagnet and an action portion (movable iron core, rod) SL1 that moves forward and backward. The solenoid has a movable iron core installed in the solenoid coil SL2 and can apply a current to the coil to cause the action portion to move straight. Although the range in which it can move is narrow (short stroke), it is small in size and can obtain a high-speed response. The solenoid coil SL2 is driven by direct current (DC solenoid) or alternating current (AC solenoid). The AC solenoid has a constant force to attract the movable iron core, and the operation speed is relatively fast.The DC solenoid is smaller than the AC solenoid, and the sound is low, but the force to be attracted varies depending on the position of the movable iron core and the operation speed is slow Has characteristics.

  As shown in FIGS. 5 and 6B, in the state where the solenoid SL is activated and the action portion SL1 is fitted in the opening C2 of the case C, the case C cannot be removed (opposite to the solenoid SL). The claw C1 is provided on the side, and is hooked on the end of the main body member 51). On the other hand, when the action part SL1 is drawn into the solenoid coil SL2 as shown in FIG. 6A, the claw C1 can be opened around the center, and the case C can be removed by pulling it downward. Can do.

  FIG. 7 is a block diagram for explaining the operation of the lock mechanism (solenoid SL). In the figure, S is a power on / off detection mechanism for detecting the power on / off state of the gaming machine, and DRV is a drive unit that receives the output of the power on / off detection mechanism S and drives the solenoid coil SL2. A specific example of the power on / off detection mechanism S will be described later.

  8 and 9 are operation flowcharts of the locking mechanism. Hereinafter, the operation will be described with reference to these drawings.

  When the power of the gaming machine is turned on from off, the power on / off detection mechanism S monitors the power on (S1). When the power is turned on (YES in S2), the lock mechanism is activated and the cover C is locked. Specifically, the power-on / off detection mechanism S causes the operating portion SL1 of the solenoid SL to project by engaging the opening C2 by causing a current to flow through the solenoid coil SL2 by the drive portion (lock mechanism drive portion) DRV. So that the cover C cannot be opened.

  When the power of the gaming machine is turned off from on, the power on / off detection mechanism S monitors the power off (S11). When the power is turned off (YES in S12), a timer (not shown) is started (S13). This timer is built in, for example, the power on / off detection mechanism S. When it is determined that the predetermined time has elapsed due to the time measured by the timer (YES in S14), the lock mechanism is released. Specifically, the power on / off detection mechanism S stops the current from the drive unit DRV to the solenoid coil SL2 (or the power supply on / off detection mechanism S causes the drive unit DRV to flow a current in the reverse direction to the solenoid coil SL2). The action portion SL1 of the solenoid SL is returned into the solenoid coil SL2. In this state, the cover C can be opened. Note that unlocking after a predetermined time (for example, 1 minute) has elapsed by the timer is, in other words, trying to make it difficult for fraudulent behavior by waiting for a certain period of time until the cover C can be opened (unauthorized). The action is done quickly to avoid that exposure).

  As is apparent from the above description, in the gaming machine according to the embodiment of the present invention, the cover that covers the control unit, which is a main component, cannot be opened when the power is turned on. The cover cannot be opened unless a predetermined time elapses after the power is turned off.

  According to the embodiment of the invention, the cover cannot be opened unless the power is turned off, and the substrate and harness covered by the cover cannot be touched. Therefore, it is possible to prevent troubles such as short-circuiting the substrate by accidentally inserting and removing the harness even when the power is turned on during maintenance.

  Further, according to the embodiment of the invention, since the cover cannot be opened unless the power is turned off, unauthorized substrate replacement can be prevented. In addition, by preventing the cover from being opened unless a predetermined time has elapsed by the timer, it is possible to prevent unauthorized acts more reliably.

  Next, a specific example of the lock mechanism (particularly, the power on / off detection mechanism S in FIG. 7) in the embodiment of the present invention will be described with reference to FIGS. In FIGS. 10 and 11, the display of the timer is omitted.

(Specific Example 1) See FIG. 10A. The solenoid coil SL2 is driven by the output of the power supply device (power supply unit) PS1, which is the power supply of the gaming machine. Simple configuration and high reliability. However, when the wiring from the power supply device PS1 to the solenoid coil SL2 is cut, there is a drawback that the lock mechanism is invalidated.
In FIG. 10A, the power switch PWS corresponds to the power on / off monitoring mechanism S, and the power device PS1 corresponds to the drive unit DRV.

(Specific Example 2) Refer to FIG. 10B. A power supply device PS2 for the solenoid coil SL2 is provided, and a power switch PWS is provided on the output side while the power supply device PS2 is always turned on. In this case, the power switch PWS has two linked contact points, one of which turns on and off the power supply device PS2, and the other turns on and off the power supply device PS1. In this configuration, since a separate power supply is provided for the lock mechanism, the power supply of the gaming machine body does not drop due to a trouble of the lock mechanism (such as a short circuit or burnout of the solenoid coil SL2).

  In FIG. 10B, the power switch PWS corresponds to the power on / off monitoring mechanism S, and the power device PS2 corresponds to the drive unit DRV.

(Specific Example 3) Refer to FIG. 10C. The power supply device PS2 for the solenoid coil SL2 is provided, and the output of the power supply device PS1 is directly monitored by the power supply on / off monitoring mechanism S while the power supply device PS2 is always turned on. The power on / off monitoring mechanism S includes a comparator CMP that compares the output (for example, + 5V) of the power supply device PS1 with a reference voltage source VREF that outputs a predetermined threshold voltage (for example, + 2.5V). When the comparator CMP determines that the output of the power supply device PS1 exceeds the threshold, the relay RLY is driven to drive the solenoid coil SL2 with the power supply of the power supply device PS2. In this configuration, since a separate power source is used for the lock mechanism, the same effects as in the second specific example are obtained, and the output of the power supply device PS1 is directly monitored by the power on / off monitoring mechanism S. The lock mechanism is not affected even if it is subjected to various work, and therefore, it is possible to reliably detect fraud.

(Specific Example 4) See FIG. 11 (a) Specific Example 3 in that the power supply device PS2 for the solenoid coil SL2 is provided, and the output of the power supply device PS1 is directly monitored by the power supply on / off monitoring mechanism S while the power supply device PS2 is always turned on. In Example 4, the temperature of the heating element H is measured to determine whether the power is on. The heating element H generates heat upon receiving the output of the power supply device PS1, and is a resistor, for example. The heating element H can be used not only for the lock mechanism but also for generating heat such as a resistor or IC mounted on the substrate. The heating element H generates heat when the power is on and does not generate heat when the power is off. Therefore, the on / off state of the power source can be determined based on the temperature of the heating element H. The temperature sensor TS is for that purpose, and the temperature sensor T is in thermal contact with the heating element H (there is little thermal resistance between them). When the power is turned on, the temperature sensor TS is considered to be at a certain temperature or higher, so that the reference temperature level TREF is determined in consideration of this. Then, when exceeding this, the comparator CMP determines that the power is on, and when not exceeding, determines that the power is off. Examples of the temperature sensor include a metal resistance temperature sensor that measures temperature based on a resistance value increasing as the temperature rises, and a semiconductor temperature sensor (thermistor) that uses a negative resistance of a semiconductor.

  Specific example 4 has the same operational effects as specific example 3, and from the relationship of the heat capacity of heat generating element H itself (more precisely, the heat capacity of temperature sensor TS), its temperature rises and falls (in other words, heat generating element). Since time is required for heating and cooling of H), it is possible to give a time delay to the lock and release thereof. Although the timer processing is performed in the above-described processing, there is a feature that it becomes unnecessary. Further, when the heating element H is a component that generates heat, such as a resistor or an IC, provided on the substrate, and the temperature sensor TS is in close contact therewith, it is possible to directly detect power-on of the substrate. Therefore, it is difficult to hinder the operation of the power on / off monitoring mechanism S, and it can be said that it is more effective against fraud.

(Specific example 5) See FIG. 11 (b) Specific example 3 in that the power supply device PS2 for the solenoid coil SL2 is provided, and the output of the power supply device PS1 is directly monitored by the power supply on / off monitoring mechanism S while the power supply device PS2 is always turned on. In the fourth specific example, whether or not the power is on is determined by directly detecting the operation state of the power supply device PS1 with the vibration sensor VS. Generally, the power supply device vibrates somewhat during its operation. Focusing on this point, the vibration sensor VS determines whether the power is on or off. The vibration sensor VS is in close contact with the power supply device PS1. Since the vibration sensor VS is considered to detect a certain level of vibration when the power is turned on, the reference vibration level REF is determined in consideration of this. Then, when exceeding this, the comparator CMP determines that the power is on, and when not exceeding, determines that the power is off. As a vibration sensor, there are an electromagnetic induction type, a piezoelectric type, a strain gauge type, and a capacitance type.

  Specific example 5 has the same operational effects as specific example 3. Unlike the specific example 4, the specific example 5 can immediately detect the on / off of the power supply device PS1.

  In addition, from the viewpoint of preventing fraud, in any of the above specific examples 1 to 5, it is preferable to provide the components constituting them in the cover C.

  In the above description, a description has been given by taking a pachinko machine as an example. However, the above-described locking mechanism can be similarly applied to a slot machine, and the operation and effects thereof are not different.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
