Description

[Detailed Description of the Invention] <Industrial Application Field> 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 a single key card. This invention relates to an unlocking device for a pachinko machine.

<Conventional technology> Conventionally, in Japanese Patent Publication No. 53-31053, etc.
An unlocking device for a pachinko machine has been proposed in which an unlocking solenoid is attached to the glass frame locking device of the pachinko machine, and the glass frame is electrically unlocked. This type of unlocking device that electrically unlocks the lock using a solenoid is configured such that a switch board is installed in the prize exchange area or control room to operate 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 is 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 and magnetic locks used in the locking devices of pachinko machines that perform
There has been a demand for an unlocking device that operates a solenoid to unlock directly electrically without using mechanical parts, from the viewpoint of reliability and weight reduction of the device.

Therefore, it is possible to use a magnetic card type key device that is already used in general door locking devices, etc., but with this type of key device,
The unlocking code (number) for the lock is magnetically written 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. There is a problem in that the circuit configuration of the device becomes complicated and the price of the unlocking device increases, and if the magnetic code recorded on the key card is disturbed by external magnetism, it becomes 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. Each lock can be unlocked individually with a single key card, and the circuit configuration for reading key codes is simpler than reading magnetic codes, and there are fewer malfunctions and breakdowns. The present invention provides an unlocking device for a pachinko machine that can automatically sequentially unlock the glass frames, etc. of a plurality of pachinko machines, and is configured as follows.

That is, the unlocking device for a pachinko machine of the present invention is as follows:
In a pachinko machine unlocking device that is equipped with a glass frame unlocking mechanism and a front frame unlocking mechanism that are operated by a solenoid, a key card with a magnetic layer and a color pattern on the surface that is color-coded according to the key number, and this key are used. It has a space into which the card is inserted, and has at least two color patterns on the surface of the inserted key card.
A key number reader with multiple optical sensors placed facing the space to distinguish between light and dark types, and a key number reader placed facing the space of the reader to detect the presence or absence of a magnetic layer on the key card. The magnetic head that sets the key number, the setting device that sets the key number for unlocking the front frame and glass frame, and the key signal sent from the reader when inserting the key card and the key setting signal from the setting device are compared and matched. When this happens, a comparator that outputs a matching signal, a matching signal from the comparator, a front frame signal or glass frame signal sent from the reader, and a magnetic detection signal from the magnetic head are input, and a control circuit that outputs an unlocking signal for a plurality of pachinko machines; 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 full-open switch;
and is configured to operate a solenoid in response to the output of an unlock signal.

<Example> Hereinafter, an example of the present invention will be described 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 the 2nd one is a key card used as a key.
As shown in the figure, the key card 1 is made of a synthetic resin plate cut into a rectangle of an appropriate size, and ten colored marks 1a to 1j are similarly placed on the front and back of the key card 1. Among these color marks, four specific color marks 1a to 1d represent the numerical value of the 1 digit of the key number, and the color mark 1a is "8", the color mark 1b is "1", and the color mark 1c is "1".
is set to indicate "2", the color mark 1d is set to indicate "4", and the other four color marks 1e to 1h are set to indicate the numerical value of the 10th digit of the key number, and the color mark 1e is set to indicate "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". Furthermore, the color mark 1i is set to indicate a front frame, and the color mark 1j is set to indicate a glass frame. And these color marks 1a
~1j are recognized 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), and are recognized as "dark". ”, these color marks 1a to 1j have no meaning. i.e. key number "37"
When setting, color mark 1a is colored "dark", color marks 1b, 1c, and 1d are colored "light", and the digit of 1 is set to "7" in "1+2+4=7".
Color marks 1f and 1g are colored "dark", color marks 1e and 1h are colored "light", and "2+1=
Key card 1 so that the 10th digit is "3"
Set the key number to . The colors that the reader 2 reads as "bright" depend on the characteristics of the optical sensor, but are, for example, "pink, yellow, purple, sky blue, yellow-green," and the colors that are read as "dark" are, for example, " black, brown, etc.

By the way, since the optical sensor of the reader 2 detects "brightness or darkness" only in the color marks 1a to 1j on the key card 1 shown in FIG. It has nothing to do with the number. 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, the color pattern shown in Figure 3 will be created as an example. Then, the presence of color marks 1a to 1j is camouflaged, and the third
It is possible to hide the existence of the color mark from others. In this case, for example, the fabric of key card 1 is white,
Color the key card 1 colorfully so that part A is pink, part B is yellow, part C is purple, part D is sky blue, part E is black, and parts F and G are dark brown.
Camouflage the presence of colored marks. In addition,
The color marks 1a to 1h as described above are similarly attached to both the front and back sides of the key card 1, and the color marks 1i and 1j on the back side of the key card 1 are 1i and 1j, contrary to FIG.
Colored so that i is "dark" and 1j is "light",
When the key card 1 is inserted into the reader 2 with the back facing up, the glass frame is unlocked, so that the front frame and the glass frame can be unlocked separately with the front and back of the key card 1. .

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, and has a structure that its existence is not visible from the front and back sides. It's summery. Further, this magnetic layer 20 does not record magnetic codes, but merely has a magnetized layer.

The reader 2, as shown in the cross-sectional view of FIG.
There is a space 2a behind the slit hole for inserting the key card 1, and on the upper side of this plate-shaped space there are marks 1a to 1j of the key card 1 corresponding to the color marks 1a to 1j as shown in FIG. An optical sensor 2b is disposed at each of the two. A total of 10 optical sensors 2b are arranged at predetermined positions, and a reflective type photo sensor in which a light emitting diode and a phototransistor are integrated is used as the optical sensor 2b.

Further, the reader 2 has a magnetic head 21 that is arranged to read the magnetic layer 20 of the key card 1 inserted into the space 2a.
It is installed in a position where it 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 outputs, for example, a high level or low level magnetic detection signal when detecting magnetism. It is possible to create an extremely simple circuit that outputs output 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. For example, a BCD-decimal decoder is used in this control circuit 3, and when 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 10, and a match signal and a magnetic detection signal are input. When the glass frame signal and the magnetic detection signal are input, it operates to send an unlocking signal for the glass frame to the output circuit 8.

The output circuits 8 and 10 are composed of one-shot circuits, and when an unlock signal is input, one pulse signal with a width of several hundred milliseconds is sent to the next stage drive circuits 9 and 11.
The drive circuits 9 and 11 are composed of switching circuits such as relays and transistors, and when a one-shot signal is input, the relays are turned on for a short time, and the solenoid 13 or the solenoid provided in the glass frame unlocking mechanism 12 is turned on. They are respectively connected so as to energize a solenoid 15 provided in the front frame unlocking mechanism 14.

These reader 2, control circuit 3, output circuits 8, 10, and drive circuits 9, 11 are attached to each pachinko machine.

On the other hand, a comparator 4 and a setting device 5 are installed for each pachinko machine in a control panel arranged in a control room or the like of a pachinko game hall, and a full-open switch 16 and a shogi knockdown circuit 17 are also installed. The comparator 4 is composed of a digital comparator, and the key signal sent from the reader 2 (a two-digit BCD signal composed of the output signals of eight optical sensors 2b, 0 to
It is connected so that the key setting signal (BCD signal indicating the key number from 0 to 99) sent from the setting device 5 is inputted, and the key signal and key setting signal are input. When they match, they are connected to output a matching signal to the control circuit 3 of each pachinko machine. The setting device 5 is composed of a digital switch, sets a key number, and outputs a key setting signal. Note that the comparator 4 is provided for each pachinko machine, but if the key numbers of the pachinko machines are common, only one setter 51 may be provided. Further, the control panel may be provided with a display that digitally displays the key numbers of the key signal and key setting signal input to the comparator 4.

The shogi knockdown circuit 17 is a well-known circuit that includes a sequential timer, a counter, etc., and sequentially outputs signals to a plurality of output terminals, and is connected to the full-open switch 16 for starting. This shogi defeating circuit 1
The multiple output terminals 7 are output circuits 3 of each pachinko machine.
When the full open switch 16 is turned on, an unlocking signal is sequentially outputted from the shogi knockdown circuit 17 to the output circuit 3 of each pachinko machine.

The front frame unlocking mechanism 14 is a known unlocking mechanism 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 a solenoid 15. This is a structure to be released. The glass frame unlocking mechanism 12 is a known unlocking mechanism that is 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. This is a structure to be released. Note that the front frame unlocking mechanism 14 is operated by a solenoid 15.
is activated, and once the locking hook is released, the unlocked state is mechanically maintained and solenoid 1 is activated.
5 or 13 can be energized for a short time, preventing heat generation. Further, 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.

When unlocking the table frame, use the designated key card 1
Insert it face up through a slit hole provided in a part of the pachinko machine, and insert it into the reader 2. First, the magnetic layer 20 of the card is detected by the magnetic head 21, and a magnetic detection signal is output from the detection circuit of the magnetic head to the control circuit 3 for a certain period of time.

Furthermore, for example, when the key card 1 has a color pattern as shown in FIG.
b, this pattern is detected as "bright" and "dark" at the predetermined color mark, and the key signal indicating the key number "37" is sent from the reader 2 to the comparator 4 as a 2-digit BCD signal. Furthermore, a table frame signal indicating the table frame is sent to the control circuit 3 from the optical sensor 2b that detects the color mark 1i. Comparator 4
Now, the key setting signal from the setter 5, in which the key number "37" has been set in advance, is compared with the key signal, and when they match, a matching signal is outputted from the comparator 4 to the control circuit 3. In this way, when the magnetic detection signal, table frame signal, and coincidence signal are sent to the control circuit,
An unlocking signal for the table frame is output from the control circuit 3 to the output circuit 10.
A one-shot signal is sent from the output circuit 10 to the drive circuit 11, and the relay or switching element in the drive circuit 11 is turned on for a short period of, for example, several hundred milliseconds, thereby energizing the solenoid 15. . When the solenoid 15 is momentarily energized, the front frame unlocking mechanism 14
The locking hook is removed and the front frame unlocking mechanism 14 becomes unlocked, but the unlocking of the locking hook is mechanically maintained even after the solenoid 15 is deenergized. In this state, the front frame of the pachinko machine can be opened freely by hand. On the other hand, if the key card 1 is incorrect, the key signal input to the comparator 4 and the key setting signal do not match, so no matching signal is output from the comparator 4, or the magnetic detection signal or the table frame No signal is sent, so 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, a predetermined key card 1 is inserted face down into a slit hole of a pachinko machine, and then inserted into a reader 2. At this time, a magnetic detection signal is sent from the magnetic head 21 to the control circuit 31, and the optical sensor 2b of the reader 2 sends a magnetic detection signal to the key card 1.
A BCD key signal indicating the key number 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. In comparator 4,
The key setting signal from the setting device 5 in which the key number is set in advance is compared with the key signal, and when the key signal matches the key setting signal, a matching signal is output to the control circuit 3. When the magnetic detection signal, the glass frame signal, and the coincidence signal are input to the control circuit 3, an unlock signal for the glass frame is sent from there to the output circuit 8, and as a result, a one shot signal is output from the output circuit 10. The relay or switching element of the drive circuit 9 is turned on. With this, solenoid 13
When the solenoid 13 is energized, the locking hook of the glass frame unlocking mechanism 12 is released, and the glass frame unlocking mechanism 12 is placed in the unlocked state. At this time, since the glass frame is biased in the opening direction by a spring, it is released from the front frame, and the glass frame is opened only by energizing the solenoid 13 for a moment. On the other hand, key card 1
If it is incorrect, the comparator 4 will not output a matching signal, or the magnetic detection signal or the glass frame signal will not be sent to the control circuit 3, and the glass frame will not be unlocked.

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. Unauthorized unlocking is almost impossible. In addition, since the magnetic layer formed on the key card 1 simply has magnetism, it is not affected by external magnetism unlike a card with a magnetic code written on it, and its detection circuit is also It becomes extremely easy.

On the other hand, in order to automatically open the glass frames of all pachinko machines in order to adjust pachinko nails, etc., the full opening switch 16 is turned on. Fully open switch 16
When 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. Therefore, 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. In pachinko parlors, etc., the maximum instantaneous current flowing through the power supply can be suppressed, allowing use within the allowable range of commercial power supplies.

In addition, the control circuit 3 receives a magnetic detection signal, 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. Further, each of the solenoids 13 and 15 can be provided with a separate circuit that is activated by a manual switch when a failure occurs in the circuit. Further, an intermediate stop switch for stopping the shogi knock-down circuit 17 midway after it starts can be connected to the shogi-knock-down circuit 17, and the front frame can be sequentially unlocked by the shogi-knock-down 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,
A key card is inserted into a reader equipped with an optical sensor to read the key number, and a magnetic head detects the presence or absence of a magnetic layer, making it suitable for unlocking devices that use magnetic cards with unlock codes recorded on them. compared,
The detection circuit and key number reading circuit can be simplified. In addition, since both color patterns and magnetism are used, unauthorized unlocking due to the structure of the key card is difficult, and the key card is not affected by external magnetism and has excellent durability for a long period of time. can be used. 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 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.
