Description

[Detailed Description of the Invention] <Industry> Second Field of Application The present invention electrically unlocks the locking device for the glass frame and front frame (wooden frame) of a pachinko machine by a solenoid using one key card. This invention relates to an unlocking device for a locked pachinko machine.

<Prior Art> Conventionally, in Japanese Patent Publication No. 53-31053, etc., an unlocking device for a pachinko machine is disclosed in which an unlocking solenoid is attached to a glass frame locking device of a pachinko machine, and the glass frame is electrically unlocked. Proposed.

This type of unlocking device that electrically unlocks the lock using a solenoid is configured so that a switch board is installed in the prize exchange base or control room to activate each solenoid, and the lock is unlocked from there. There is also a need for an attendant to unlock each pachinko machine from the outside using a key, such as when a pachinko ball gets stuck during a game.

<Problems to be solved by the invention> For these reasons, a method was considered in which a key switch was attached to the locking device of each pachinko machine and the key was inserted to turn on the switch. Instead of the cylinder locks or magnetic locks used in pachinko machine locking devices, an unlocking device that uses a solenoid to operate directly electrically without any mechanical parts improves device reliability and reduces weight. This was requested from the viewpoint of

Therefore, it is possible to use a magnetic card type key device that is already used in general door locking devices, etc., but in this type of key device, the unlock code (number) of the lock is written magnetically on the key. The key card is inserted into the locking device, the magnetic code is read, and if the codes match, the lock is unlocked. This complicates the circuit configuration of the magnetic code reading device and increases the price of the unlocking device. In addition, there was a problem in that the magnetic code recorded on the key card was disturbed by external magnetism, making it unusable.

Means for Solving the Problems> The present invention has been made in view of the above points, and it is possible to simplify both the front frame unlocking mechanism and the glass frame unlocking mechanism of a pachinko machine, which are unlocked by the operation of a solenoid. Locks can be unlocked individually with a single key card, and the circuit configuration for reading key codes is simpler than reading magnetic codes.
There are fewer malfunctions and breakdowns, and the glass frames of multiple pachinko machines can be automatically unlocked one after another by operating the full-open switch, and key code settings can be easily and safely changed using remote control. The present invention provides an unlocking device for a pachinko machine, which is configured as follows.

Namely, the unlocking device for a pachinko machine of the present invention is a pachinko machine unlocking device that is provided with a glass frame unlocking mechanism and a front frame unlocking mechanism that are unlocked by a solenoid, and has a color pattern that is color-coded according to the key number. a key card having a magnetic layer on its surface; a space into which the key card is inserted; A key number reader disposed opposite the unit, a remote control receiver that controls the key number setting operation set by the setting device according to the received signal, and a key number setting control for the remote control receiver. A comparator that compares the key signal sent from the reader when the key card is inserted with the key setting signal from the setting device and outputs a match signal when they match. , a control circuit that inputs the match signal from the comparator, the front frame signal or glass frame signal sent from the reader, and the magnetic detection signal from the magnetic head, and outputs the unlock signal for the front frame or glass frame, and A shogi knockdown circuit that sequentially outputs unlocking signals for the front frame or glass frame of a plurality of pachinko machines by operating a switch, and is configured to operate a solenoid in response to the output of the unlocking signal. .

<Example> Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a block diagram of a pachinko machine unlocking device.

1 is a key card used as a key, and as shown in Figure 2, it is made of a synthetic resin board cut into a rectangle of an appropriate size, and the front and back of the key card 1 have 10 colored marks. la to 1j are similarly assigned. Among these color marks, four specific color marks 1a to 1d represent the numerical value of the 1 digit of the key number, and 1 color mark 1
a is "8", color mark 1b is "l", color mark IC
is set to indicate "2", the color mark 1d is set to indicate "4", and the other four color marks 1e-1h are set to indicate the key number 10.
It represents the numerical value of the digit, and the color mark le is "2",
The color mark 1f is set to indicate "4," the color mark 1g is set to indicate "8," and the color mark 1h is set to indicate "1." Also,
The color mark li is set to indicate the front frame, and the color mark 1j is set to indicate the glass frame. These color marks 1a to 1j are displayed as numerical values with meanings only when they are detected as "bright" by the optical sensor of the reader 2 (described later) (when the detection signal of the optical sensor is higher than the set level). When recognized and detected as "dark", these color marks 1a to 1j have no meaning. In other words, when setting the key number to "37", color mark 1
Color a “dark” and mark one color mark lb, lc, ld as “
rt+2+4=74, the digit of 1 is set to "7", the color marks if and 1g are colored "dark", the color marks 1e and 1h are colored "bright", and the result is "2+1=3". So 10
Set the key number on the key card 1 so that the digit is "3". In addition, the color that reading base 2 reads as "bright" is
Depending on the characteristics of the optical sensor, for example, colors may be "pink, yellow, purple, sky blue, yellow-green", etc., and colors read as "dark" may be, for example, "black, brown", etc.

By the way, the color mark l on the key card 1 shown in FIG.
Since the optical sensor of the reader 2 detects the "brightness and darkness" of only the parts a to 1j, the color of the other parts is unrelated to the key number. So, for example, if you make a key card 1 with the key number "37" that unlocks the front frame on the front side of the card and unlocks the glass frame on the back side, - for example, the color as shown in Figure 3 will be created. The color marks 1a to 1j become a pattern, and the presence of the color marks 1a to 1j can be camouflaged and the presence of the color marks can be hidden from a third party.

In this case, for example, the fabric of key card 1 is white, part A is pink, part B is yellow, part C is purple, part is sky blue, part E is black, and parts F and G are dark brown. Card 1 is colored colorfully to camouflage the presence of the colored mark. In addition, the color mark la~ as above
1h is attached in the same way on both the front and back sides of the key card 1, and the color marks li and IJ on the back side of the key card 1 are colored so that 1i is "dark" and lj is "light", contrary to FIG. 3. , so that when the key card 1 is inserted into the reader 2 with the back facing up, the front frame and the glass frame can be unlocked separately with the front and back of the key card 1, so that the glass frame is unlocked. There is.

Furthermore, a magnetic layer 20 is formed on the front and back of a part of the keyboard 1 by painting, coating, etc., and this magnetic layer 20 is formed under the above-mentioned colored coating, so that its existence cannot be seen from the front and back sides of the keyboard 1. It has become. Further, this magnetic layer 20 does not record magnetic codes, but merely has a magnetized layer.

As shown in the sectional view of FIG. 4, the reader 2 has a space 2a at the rear of the slit hole into which the key card 1 is inserted. Optical sensors 2b are arranged at positions corresponding to the color marks 1a to 1j of the key card 1 as shown. A total of ten optical sensors 2b are arranged at predetermined positions, and the optical sensors 2b are reflective photosensors that integrate a light emitting diode and a phototransistor.

Further, the reader 2 has a magnetic head 21 in the space 2a.
The magnetic layer 20 of the key card 1 inserted into the key card 1 is attached at a position through which the magnetic layer 20 passes. Since this magnetic head 21 detects the presence or absence of the magnetic layer 20, a detection circuit including an amplifier connected to the magnetic head 21 generates, for example, a high level or low level m-detection signal when detecting magnetism. It is possible to create an extremely simple circuit that outputs for a certain period of time.

3 is a control circuit which inputs a front frame signal or a glass frame signal from the reader 2 and also inputs a coincidence signal from a comparator 4, which will be described later, and generates an unlock signal for the front frame according to these input signals. It has a structure that outputs an unlock signal for the glass frame to each output circuit. This control circuit 3 includes, for example, a BCD-1
When a 0-decimal decoder is used and a match signal, a front frame signal, and a magnetic detection signal are input, an unlock signal for the front frame is sent to the output circuit IO, and a match signal, a glass frame signal, and a magnetic detection signal are input. When input, it operates to send an unlocking signal for the glass frame to the output circuit 8.

The output circuits 8 and 1O are constituted by one-shot circuits, and when an unlocking signal is input, they output one pulse signal having a width of, for example, several hundred milliseconds to the next-stage drive circuits 9 and 11, respectively.

The drive circuits 9 and 11 are composed of switching circuits such as relays and transistors, and when a one-shot signal is input, they turn on the relays etc. for a short time and open the glass frame unlocking mechanism 12.
The solenoid 13 provided in the front frame unlocking mechanism 14 or the solenoid 15 provided in the front frame unlocking mechanism 14 are respectively connected so as to be energized.

These reader 2, control gIJ circuit 3, output circuit 8.10, and drive circuit 9.11 are installed in each pachinko machine.

On the other hand, a control panel is installed in a block (generally called an "island") where a large number of pachinko machines are installed in a pachinko'M play hall, including a comparator 4, a setting device 5, and a full-open switch 1.
6. A shogi knockdown circuit 17 is provided on the control panel, and a remote control receiver 411 that controls the setting device 5 is provided.
23 will be installed on part of the "island". The comparator 4 is composed of a digital comparator, and receives the key signal sent from the reader 2 (a two-digit BCD signal composed of the output signals of eight optical sensors 2b, indicating a key number from 0 to 99). It is also connected to input the key setting signal (BCD signal indicating the key number from 0 to 99) sent from the setting device 5, and when the key signal and key setting signal match, the matching signal is sent to each pachinko machine. It is connected to output to the control circuit 3 on the machine side. The setting device 5 is composed of a plurality of digital switches, each digital switch can set a key number arbitrarily, each digital switch is selectively switched by a changeover switch, and one digital switch is a remote It has a structure in which the digital setting value is selected by operation and output as a key number. The remote control transmitter 24 and the remote control receiver R23 are used to switch and control the key numbers set and output in the setting device 5 by remote control, and the remote control transmitter a24 is installed, for example, at the counter or management room of a pachinko game machine. Remote control receiver 23 in the U4 control panel installed on the “island”
A signal is sent to switch the key number.

For example, an infrared remote control transmitter/receiver can be used as the remote control transmitter/receiver 24.23, and the transmitter includes an oscillator for the carrier wave, a key switch input circuit for inputting the transmission code, and a key switch input circuit for inputting the code for transmission. a pulse signal generator that generates a digital code signal;
It is comprised of an output synthesis circuit that synthesizes a carrier wave and a pulse signal, and a light projecting element (for example, an LED) that receives the pulse signal from the output synthesis circuit and emits infrared rays. Therefore, when the key switch No. 3, for example, of the remote control transmitter 24 is pressed, a digital signal indicating the code corresponding to No. 3 is transmitted from the LED on an infrared ray.

On the other hand, the receiver includes a light receiving element such as a photodiode that receives infrared light transmitted from an LED, a signal input circuit that amplifies the signal received by the light receiving element, performs wave detection and waveform shaping to obtain a pulse signal, and a data signal of a predetermined bit. It consists of a shift register that takes in data and checks the data, a latch circuit that latches the data signal from the shift register, and a signal output circuit that outputs the latched data in parallel for each bit via an output buffer. Therefore, the receiver receives the infrared signal transmitted from the remote control transmitter a24 with the light receiving element, latches the multi-bit data signal with the latch circuit, and outputs the digital code signal of each bit in parallel from each output terminal. A signal is sent to the setting device 5 to switch the key number. The light emitting element of the remote control transmitter a24 and the light receiving element of the remote control receiver 23 are installed facing each other so that the light is not blocked between the counter and the "island".
Since the key number setting changeover of the setting device 5 can be remotely controlled, there is no need to install the setting device 5 at the counters of the four stores, and there is no need to install the setting device 5 at the counters of the four stores.
It is possible to eliminate the need for space and equipment for providing lines. In addition, in order to check the reception status of the signal transmitted from the remote control transmitter 24 on the transmitter side, another transmitter is provided on the remote control receiver 23 side, and a signal from another transmitter is provided on the remote control transmitter 24 side. It is also possible to provide a separate receiver for receiving the acknowledgment signal. In addition to infrared rays, remote control can also be performed using radio waves and ultrasonic waves.

Usually, a display device is used to display the key number of the key signal input to the comparator 4 and the key setting signal set to the setting device 5.
This is because the setting key number can be changed by remote control from the store counter without opening the control panel.

It is possible to prevent the setting key number from being seen by a person and thereby causing unauthorized unlocking.6 The shogi defeating circuit 17 is composed of a sequential timer, a counter, etc., and is a well-known method that sequentially outputs signals to a plurality of output terminals. The full open switch 16 is connected for starting. The plurality of output terminals of this shogi knockdown circuit 17 are connected to the input side of the output circuit 3 of each pachinko machine, and when the full open switch 16 is turned on, an unlock signal is sequentially sent from the shogi knockdown circuit 17 to the output circuit 3 of each pachinko machine. Output.

The front frame unlocking mechanism 14 is a known unlocking mechanism 1j14Ii that is attached to the main body frame side or the front frame of the pachinko machine, and is engaged with a locking hook attached to the opposite position of the front frame or the main body frame by the operation of the solenoid 15. This is a structure to be released. The glass frame unlocking mechanism 12 is a known unlocking mechanism attached to the front frame of a pachinko machine, and the engagement between a hook provided on the glass frame and a locking hook on the front frame is controlled by the operation of a solenoid 13. The front frame unlocking mechanism 14 has a structure for unlocking, and the solenoid 1
5 is activated and once the locking hook is released,
The unlocked state is maintained mechanically, and the solenoid 15 or 13
It only takes a short time to energize, which prevents heat generation. Furthermore, the front frame unlocking mechanism 14 and the glass frame unlocking mechanism 12 have a structure in which when the front frame or glass frame is closed, each locking hook or hook portion is biased by a coil spring or the like and automatically becomes locked. It is.

Next, the operation of the pachinko machine unlocking device having the above configuration will be explained.

First, setting the key number will be explained. A plurality of usable key numbers are set in advance in the setting device 5 so as to be switchable. In a pachinko game machine, for example, a key number to be used on that day is set when the store is opened, and a key card corresponding to that key number is used as the key for that day. The setting of the key number is performed, for example, by operating the remote control transmitter fi24 from the store counter (for example, pressing the No. 3 key switch), and the remote control transmitter 2
A digital code signal having a code (for example, number 3) corresponding to the setting key number is transmitted on the infrared rays emitted from the light projecting element No. 4. The remote control receiver 23 receives this infrared signal via a light receiving element, and the received data signal is passed through a shift register and latched by a latch circuit, and a high level signal is output from the output terminal corresponding to the data (No. 3). Ru. This high level signal is sent to the setting device 5, which switches and selects the No. 3 digital switch, and a key signal indicating a preset key number (for example, 37) is sent to the No. 3 digital switch as the setting value. Comparator 4
is output to.

On the other hand, when unlocking the front frame, a predetermined key card l is inserted face up through a slit hole provided in a part of the pachinko machine and inserted into the reader 2. Then, first, the magnetic layer 20 of the card is detected by the magnetic head 21, and a magnetic detection signal is outputted from the magnetic head detection circuit to the control circuit 3 for a certain period of time. Furthermore, for example, if key card 1 is
When the pattern has a color pattern as shown in the figure, each optical sensor 2b detects this pattern as "bright" and "dark" at a predetermined color mark, and the key number "37" is detected by each optical sensor 2b.
The key signal indicating “” is sent to the reader 2 as a 2-digit BCD signal.
A table frame signal indicating the table frame is sent from the optical sensor 2b that detects the color mark 11 to the control circuit 3.
sent to. The comparator 4 compares the key setting signal from the setting device 5 to which the key number "37" has been set in advance with the key signal, and when they match, a matching signal is output from the comparator 4 to the control circuit 3. . In this way, when the magnetic detection signal, table frame signal, and matching signal are sent to the control circuit, the control circuit 3
An unlock signal for the table frame is output from the output circuit 10, and a one-shot signal is sent from the output circuit 10 to the drive circuit 11, and the relays and switching elements in the drive circuit 11 are turned on for a short period of, for example, several hundred milliseconds. As a result, the solenoid 15 is energized. Then, when the solenoid 15 is momentarily activated, the locking hook of the front frame unlocking mechanism 14 is removed and the front frame unlocking mechanism 14 becomes unlocked, but the locking hook is released by the solenoid. 15 is mechanically held even after deenergization. In this state, the front frame of the pachinko machine can be freely opened by hand. On the other hand, the key card
If the key signal input to the comparator 4 is invalid, the key signal input to the comparator 4 and the key setting signal will not match, so a matching signal will not be output from the comparator 4, or a magnetic detection signal or a table frame signal will not be sent. Therefore, the control circuit 3 does not output an unlocking signal, and the solenoid 15 of the front frame unlocking mechanism 14 does not operate.

When unlocking the glass frame, insert the specified key card l face down into the slit hole of the pachinko machine and insert it into the reader 2. At this time, a magnetic detection signal is sent from the magnetic head 21 to the control circuit 31. Optical sensor 2b of sent reader 2
A BCD key signal indicating the key number of the key card l is sent to the comparator 4, and a glass frame signal is sent to the control circuit 3 from one of the optical sensors 2b. The comparator 4 compares the key setting signal from the setting device 5, in which the key number is set in advance, with the key signal, and outputs a matching signal to the control circuit 3 when the key signal matches the key setting signal. When the magnetic detection signal, the glass frame signal, and the coincidence signal are input to the control circuit 3, an unlocking signal for the glass frame is output from the circuit 8.
As a result, a one-shot signal is output from the output circuit 10, and the relay or switching element of the drive circuit 9 is turned on. As a result, the solenoid 13 is momentarily activated, and the solenoid 13 is energized, thereby releasing the locking hook of the glass frame unlocking mechanism 12.
The glass frame unlocking mechanism 12 is in the unlocked state. At this time, since the glass frame is urged in the opening direction by a spring, it is released from the front frame, and the glass frame is opened only by the momentary energization of the solenoid 13. On the other hand, if the key card l is invalid, the comparator 4 will not output a matching signal, or the magnetic detection signal or glass frame signal will not be sent to the control circuit 3, and the glass frame will not be unlocked. Not possible.

In this way, the glass frame or front frame is unlocked only when the magnetic detection signal, the glass frame signal or the front frame signal, and the matching signal are sent to the control circuit 3.
It is almost difficult to imitate or illegally unlock the lock. In addition, since the magnetic layer formed on the key card 1 merely has magnetism, it will not be affected by external magnetism like a card with a magnetic code written on it, and its detection circuit is also extremely sensitive. It becomes easy.

On the other hand, in order to automatically open the glass frames of all pachinko machines in order to adjust the pachinko nails, etc., the full open switch 16 is turned on. When the full open switch 16 is turned on, the shogi knockdown circuit 17 is activated, and an unlocking signal is sequentially sent from each output terminal to the output circuit 8 of each pachinko machine, and a one-shot signal is output from each output circuit 8 to the drive circuit 9. Drive port tI
39, the solenoid 13 is energized, the glass frame unlocking mechanism 12 is activated, and the glass frames of each pachinko machine are sequentially opened. In this way, when fully opening, the solenoids of each pachinko machine are not energized at the same time, and the solenoids are energized one after another to automatically open the glass frame. 1t of instants flowing into the power supply at playgrounds etc. i Suppress the maximum current to reduce the allowable commercial power supply vAIl! Can be used within tI.

In addition, the control circuit 3 receives a magnetic detection signal and a coincidence signal.

In the event of an abnormality in which the front frame signal or the glass frame signal is not input at the same time, an abnormality signal may be sent from the control circuit 3 to the alarm circuit to issue an alarm. Also, each solenoid 1
3 and 15 can be provided with separate circuits that are activated by manual switches when a failure occurs in the circuits. Furthermore, an intermediate stop switch for stopping the shogi defeating circuit 17 after it starts can be connected to the shogi defeating circuit 17, and the front frame can be sequentially unlocked by the shogi defeating circuit instead of the glass frame.

<Effects of the Invention> As explained above, according to the unlocking device for a pachinko machine of the present invention, a key card having a color pattern and a magnetic layer that is color-coded according to the key number is used, and a reader equipped with an optical sensor is used. Because the structure is such that a key card is inserted into the device and the key number is read, and a magnetic head detects the presence or absence of a magnetic layer, it requires less detection circuits and keys than an unlocking device that uses a magnetic card with an unlock code recorded. The number reading circuit can be simplified. In addition, since both a color pattern and magnetism are used, unauthorized unlocking by imitation of a key card is difficult, and the key cart is not affected by external magnetism and has excellent durability for long-term use. be able to. In addition, the color pattern of the key number is attached to both sides of the key card, and the color marks indicating the front frame and glass frame are attached separately to the front and back, so you can simply insert a single key card by changing the way it is inserted between the front and back. The front frame and glass frame of the pachinko machine can be unlocked separately. In addition, we have installed a shogi knockdown circuit that is activated by the full-open switch, and outputs the unlock signal sequentially from this circuit, so when adjusting the pachinko nails or inspecting the internal devices, you can use the glass frame or front frame of all pachinko machines. can be unlocked automatically in sequence.

Furthermore, since the key number setting changeover operation on the setting device can be performed by remote control, there is no need to use a control panel to change the key number setting while the setting display of the setting device can be seen by a person.

Key number settings can be easily and safely changed from the counter of a pachinko game machine, and wiring from the "island" to the counter etc. can be made unnecessary.
