Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to the glass frame and front frame (wooden frame) of a pachinko machine.
This invention relates to a pachinko machine unlocking device that electrically unlocks the locking device of a pachinko machine using a single key card.

<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. When a pachinko ball gets stuck during a game, there is also a need for the clerk 0 to unlock each pachinko machine from outside using a key.

<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 may be possible to use a magnetic card type key device that is already used in general door locking devices, etc., but in this type of device, the unlock code (number) of the lock is written on the key magnetically. The structure is such that the key card is written in the lock, the key card is placed in the locking device, the magnetic code is read, and if the codes match, the lock is unlocked, so complex circuits such as a magnetic code reading device and writing device are required. However, in the method of magnetically writing the code on the key card, there are problems in that the magnetism weakens over time or that the magnetic code is destroyed by bringing a magnet or the like close to it.

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 using a single key card, and the circuit configuration for reading the key code is simpler than 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 frame, etc. of a pachinko machine, and 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. The key card has a key card on its surface, and a space into which the key card is inserted, and a plurality of optical sensors are installed on the side of the space to distinguish and detect the color pattern on the surface of the inserted key card into at least two types of light and dark. A key number reader installed in the key number reader, a setting device for setting the key number for unlocking the front frame and glass frame, a key signal sent from the reader when the key card is inserted, and a key setting signal from the setting device. and a comparator that outputs a matching signal when they match, and a comparator that outputs a matching signal when they match, and a solution for one front frame or glass frame that inputs the matching signal from the comparator and the front frame signal or glass frame signal sent from the reader. It is equipped with a control circuit that outputs a lock signal, and a shogi knockdown circuit that sequentially outputs unlock signals for the front frame or glass frame of multiple pachinko machines by operating a full open switch, and a solenoid control circuit that outputs unlock signals for the front frame or glass frame of multiple pachinko machines in sequence by operating a full open switch. It is configured to operate.

<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 card used as a key, and as shown in Figure 2, it is made of a synthetic resin board cut into a rectangle of appropriate size, and the front and back of the key card 1 are decorated with 10 colors. Marks la to 1j are similarly attached. Among these color marks, four specific color marks la to 1d represent the numerical value of the 1 digit of the key number, and color mark 1
a is "8", color mark lb is "1", color mark 1c
is set to indicate "2", the color mark ld is set to indicate "4", and the other four color marks 1e-1h are set to indicate the key number lO
It represents the numerical value of the digit, and the color mark le is "2",
The color mark If is set to indicate "4", the color mark 1g is set to indicate "8", and the color mark 1h is set to indicate rlJ. Also,
The color mark 11 is set to indicate a front frame, and the color mark lj is set to indicate a glass frame. Then, these color marks la to 1j are used 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 la to 1j have no meaning. In other words, when setting the key number to "37", color mark l
Color a “dark” and color marks lb, lc, ld “
Color it "light" and set the 1's digit to "7" with rl+2+4=7J, color the color marks 1f and 1g "dark", color the color marks 1e and 1h "light", and get "2+1=3". So 10
Set the key number on the key card 1 so that the digit is "3". The color that the reader 2 reads as "bright" is
Although it depends on the characteristics of the optical sensor, the colors may be "pink, yellow, purple, sky blue, yellow-green", etc., and the colors read as "dark" may be "black, W color", etc., for example.

By the way, the color mark 1 on the key card 1 shown in Figure i2
Since the optical sensor of the reader 2 detects the "brightness and darkness" of only the part a-14, the color of the other parts is unrelated to the key number. So, for example, if you make a key card l 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. It becomes a pattern, and can camouflage the presence of the color marks 1a to 1j and hide the presence of the color marks from a third party.

In this case 1, 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 lower key card 1, and the color marks li and lj on the back side of the key card l are colored so that it is "dark" and lj is "light", contrary to FIG. 3. , when the key card l is inserted into the reader 2 with the back facing up, the glass frame is unlocked.

The front frame and the glass frame can be unlocked separately using the front and back sides of the key card 1.

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 la to 1j of the key card l as shown. A total of ten optical sensors 2b are arranged at predetermined positions, and a reflective type photosensor that integrates a light emitting diode and a phototransistor is used as the optical sensor 2b. Note that the lower part of the reader 2 between the card insertion slit hole and the detection section is open, so that even if foreign objects are inserted through the card insertion opening, they will fall downward and the foreign objects will not become clogged.

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. A BCD-decimal decoder is used in this control circuit 3, and when a match signal and a front frame signal are input, an unlock signal for the front frame is sent to an output circuit 10, and a match signal and a glass frame signal are input. The output circuit 8 and IO operate to send an unlocking signal for the glass frame to the output circuit 8 when the unlocking signal is input. One pulse signal is output 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 relay for a short time and release the solenoid 13 provided in the glass frame unlocking mechanism 12 or the front frame. Solenoid 1 provided in mechanism 14
5 are connected to each other so as to energize them.

And these reader 2, control circuit 3, output circuit 8
．． 10. A drive circuit 9.11 is installed in 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 disposed in a control room or the like of the pachinko game machine, and furthermore, a full-open switch 16 and a shogi knockdown circuit 17 are provided. The comparator 4 is composed of one digital comparator, and receives a key signal sent from the reader 2 (a 2-digit BCD signal composed of the output signals of eight optical sensors 2b, and can read key numbers from 0 to 99). It is connected to input the key setting signal (BCn signal indicating the key number from 0 to 99) sent from the setting device 5, and when the key signal and the key setting signal match, a match signal is output. is connected to be output 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 number of each pachinko machine is the same, only one setting device 5 may be used, and the key signal input to the comparator 4 and the key setting signal The control panel may also be provided with a display that digitally displays the key number held by the key.

The shogi knockdown circuit 17 is a 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. 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 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 the hook provided on the glass frame and the engaging W hook on the front frame side is controlled by the operation of a solenoid 13. This is a structure to be released. In addition, in the front frame unlocking mechanism 14, once the solenoid 15 is activated and the locking hook is released, the unlocked state is mechanically maintained, and the energization to the solenoid 15 or 13 is continued for a short time. This will help prevent overheating. 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.

When unlocking the table frame, a predetermined key card 1 is inserted face up through a slit hole provided in a part of the pachinko machine and inserted into the reader 2. For example, when the key card 1 has a color pattern as shown in FIG. 37'' is sent from the reader 2 to the comparator 4 as a two-digit BCD signal, and further, a table frame signal indicating the table frame is sent from the optical sensor 2b that detected the color mark 11 to the control circuit 3. . In the comparator 4, the key number "
The key setting signal from the setting device 5 in which "37" is set is compared with the key signal, and when they match, a matching signal is output from the comparator 4 to the control circuit 3. Then, control circuit 3
An unlock signal for the table frame is output from the output circuit 10 to the output circuit 10, 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. When the solenoid 15 is activated for a moment, 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 opened freely by hand. On the other hand, key card 1
If the key signal input to the comparator 4 is invalid, the key signal input to the comparator 4 and the key setting signal do not match, so the comparator 4 outputs a matching signal, and the control circuit 3 does not output an unlock signal. The solenoid 15 of the table frame unlocking mechanism 14 does not operate.

When unlocking the glass frame, insert the specified key card 1 face down into the slit hole of the pachinko machine and insert it into the reader 2. At this time, the optical sensor 2b of the reader 2 detects 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. 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 glass frame signal and the coincidence signal are input to the control circuit 3, an unlocking 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, and the drive circuit 9 The relay or switching element turns on. As a result, the solenoid 13 is momentarily activated, and the solenoid 13 is energized.
The locking hook of the glass frame unlocking mechanism 12 is removed, and the glass frame unlocking mechanism 12 enters the unlocked state. At this time, the glass frame is released from the front frame because it is biased in the opening direction by a spring, and the glass frame is opened only by energizing the solenoid 13 for a moment. If the card l is fraudulent, the comparator 4 will not output an unlocking signal, and the solenoid 13 of the glass frame unlocking mechanism 12 will not operate.
No unlocking takes place.

In this way, the key card 1 has one color mark 1a to 1h.
By changing the color (bright or dark), you can set a number from 0 to 99, and unlike magnetic cards, it is not affected by magnetism and can be used for a long time. Note that by increasing the number of color marks, it is also possible to freely set key numbers greater than the above.

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 circuit 9
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 a pachinko game hall or the like equipped with a large number of pachinko machines, the instantaneous maximum current flowing through the power supply can be suppressed and used within the allowable range of two commercial power sources. Incidentally, in the event of an abnormality in which the coincidence signal and the front frame signal or the glass frame signal are not input to the control circuit 3 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.

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-coded pattern according to the key number is used, and the key is inserted into a reader equipped with an optical sensor. Since the key number is read by inserting the card, it is not affected by magnetism unlike magnetic cards, and can be used for a long period of time with excellent durability.The circuit for reading the key number is also simplified. Can be done. moreover.

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 a 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.
