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 locking devices for pachinko machines, an unlocking device that uses a solenoid to operate the lock directly electrically without using mechanical parts improves the reliability and weight of the device. It was requested from this point of view.

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. The cost increases due to the need for complex circuits such as devices and writing devices, and the method of magnetically writing codes on key cards has the disadvantage that the magnetic field weakens over time or when a magnet is brought close to the key card, the magnetic code is lost. There was a problem that the .

<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. Provides an unlocking device for pachinko machines that can be unlocked individually with a single key card, has a simpler circuit configuration for reading key codes than magnetic codes, and is less likely to malfunction or break down. It is structured as follows.

That is, the unlocking device for a pachinko machine of the present invention has the following features:
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, there is a key card that has a color pattern on the surface that is color coded according to the key number, and a key card that is inserted. a key number reader, which has a space in which the key card is inserted, has a plurality of optical sensors disposed on the side of the space, and which detects the color pattern on the surface of the inserted key card by distinguishing it into at least two types of light and dark; and a table frame. and a setting device for setting the key number for unlocking the glass frame, and comparing the key signal sent from the reader when the key card is inserted with the key setting signal from the setting device,
A comparator that outputs a matching signal when a match is made; the matching signal from the comparator and the front frame signal or glass frame signal sent from the reader are input, and an unlocking signal for the front frame or glass frame is output. comprising a control circuit;
The solenoid is configured to operate in response to the output of the 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 digit at 1 of the key number, and the color mark 1a is "8", the color mark 1b is "1", and the color mark 1c is "8".
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 . Note that 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. .

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 photo sensor in which a light emitting diode and a phototransistor are integrated 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 slot, 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 the output circuit 10, and a match signal and a glass frame signal are input. When the unlocking signal for the glass frame is released, the unlocking signal for the glass frame is sent 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.
Output each. 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 activate the solenoid 13 provided in the glass frame unlocking mechanism 12 or the front frame unlocking mechanism. The solenoid 15 provided at the solenoid 14 is connected to each other so as to energize the solenoid 15 .

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 located in a management room or the like of a pachinko game hall. The comparator 4 is composed of a digital comparator, and receives a 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). ), and is connected to input the key setting signal (BCD signal indicating the key number from 0 to 99) sent from the setting device 5.
When the key signal and the key setting signal 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 5 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 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 activated by engagement with a locking hook attached to the opposite position of the front frame or the main body frame and the operation of the solenoid 15. It has an unlocking structure. 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. Then, for example, when the key card 1 has a color pattern as shown in FIG. 3, this pattern is detected as "bright" and "dark" at predetermined color marks by each optical sensor 2b, A key signal indicating this key number "37" is sent as a two-digit BCD signal from the reader 2 to the comparator 4, and a table frame signal indicating the table frame is sent from the optical sensor 2b detecting the color mark 1i to the control circuit. Sent to 3. 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,
When a match occurs, a match signal is output from the comparator 4 to the control circuit 3. Then, the control circuit 3 outputs an unlock signal for the front frame to the output circuit 10, and the output circuit 10 sends a one-shot signal to the drive circuit 11, and the relays and switching elements in the drive circuit 11 are activated for several hundred milliseconds, for example. It is turned on for a short time, thereby energizing the solenoid 15. Then, when the solenoid 15 is energized 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 of the locking hook is not released. It is mechanically held 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 an unauthorized one, the key signal input to the comparator 4 and the key setting signal do not match, so the comparator 4 does not output a matching signal, and therefore the control circuit 3 outputs an error signal. No lock signal is output, 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 BCD key signal indicating the key number of the key card 1 is sent from the optical sensor 2b of the reader 2 to the comparator 4.
Furthermore, 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, the output circuit 10
A one-shot signal is output from the drive circuit 9, and the relay or switching element of the drive circuit 9 is turned on. As a result, the solenoid 13 is energized for a moment, and by energizing the solenoid 13, the locking hook of the glass frame unlocking mechanism 12 is released, and the glass frame unlocking mechanism 12 is in the unlocked state. becomes. 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, if key card 1 is fraudulent,
The comparator 4 does not output an unlocking signal, the solenoid 13 of the glass frame unlocking mechanism 12 does not operate, and unlocking is not performed.

In this way, key card 1 has color mark 1.
A number from 0 to 99 can be set by changing the colors a to 1h, ie, "bright or dark", 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. Furthermore, in the event of an abnormality in which the coincidence signal and the front frame signal or the glass frame signal are not simultaneously input to the control circuit 3, an abnormality signal can be sent from the control circuit 3 to the alarm circuit to issue an alarm. In addition, each solenoid 13 and 15 may be provided with a separate circuit that is activated by a manual switch when a circuit failure occurs, or a circuit that sequentially unlocks the front frame or glass frame of all pachinko machines at once. can also be provided separately.

<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 that is color-coded according to the key number is used, and the key is sent to a reader equipped with an optical sensor. Since the key number is read by inserting the card, it is not affected by magnetism like magnetic cards, and can be used for a long time with excellent durability.The circuit for reading the key number is also simplified. can do. 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.
