Description

[Detailed description of the invention] <Field of application in industry> The present invention is a method of electrically locking the glass frame and front frame (wooden frame) of a pachinko machine using a single key card. The present invention relates to an unlocking device for a pachinko machine that unlocks the lock automatically.

<Prior art> Conventionally, in Japanese Patent Publication No. 53-31053, etc., an unlocking solenoid for unlocking is installed in the glass frame locking device of a pachinko machine, and the glass frame is electrically unlocked. A device has been 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 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.This requires complex circuitry such as a magnetic code reading device and writing device. 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 solve 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. A pachinko machine unlocking device that can be unlocked individually with a single key card, the circuit configuration for reading key codes is simpler than magnetic codes, and there are fewer malfunctions and breakdowns. It is provided and is structured as follows.

That is, 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. 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 inputs the matching signal from the comparator and the front frame signal or glass frame signal sent from the reader, and generates a solution for the front frame or glass frame. and a control circuit that outputs a lock signal, and is configured to operate a solenoid in response to the output of an unlock 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. 1a-13 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 1b is "1", 1 color mark 1c
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 key number 10.
It represents the numerical value of the digit, and the color mark le is "2",
Color mark 1f is "4", color mark 1g is r8J,
The color mark is set to indicate 1 h jf r l J. Further, the color mark 11 is set to indicate a front frame, and the color mark 1j is set to indicate a glass frame. These color marks 1a to 1j are read by a reader 2, which will be described later.
Only when "bright" is detected by the optical sensor (when the detection signal of the optical sensor is above the set level -F) are they recognized as numerical values with meaning attached to them, and when detected as "dark" These color marks la to 1j have no meaning.In other words, if the key number is set to "37" +iL
and)! - Do ↓), set color mark 1a to "dark"7'
5 colors, color marks 1 b, J, c, 1.
d to 1 light, 71 colors and r 1.-+-2+ 4 =
7.1 and 1's 4gir are "7" and 17, color mark 1f
Color and Ig to [111″ block], color mark 1e etc.
H to [light J with 9 colors and 10 shuttles t with "2+1-3" r
Set the key number - to key card 1 so that it is 3J. The color that the reader 2 reads as "bright" depends on the characteristics of the light sensor, but for example, it can be "pink, dark blue, purple,
They are sky blue, yellow-green, 1, etc., and the colors read as ``Sho'' are, for example, ``black, brown, etc.''.

By the way, since the optical sensor of the reader 2 detects "brightness and darkness" only in the part marked with the color mark Ja''lj of the small OKI card 11- in Fig. 2, it is difficult to determine what color the other parts are. It has nothing to do with Mogi Ichiban-J. So, for example, you could create a key card I with the number ``37'' that unlocks the front frame on the front side of the card and unlocks the glass frame on the back side, as shown in Figure 3. Color patterns roar,
By camouflaging the presence of the color marks 1a to 1j, it is possible to hide the existence 7t of the 1-inch color marks from a third party.

In this case, for example, λ is the white material of key cart 1 and [7, part A is pink, part B is D'Z color, part C is purple, part is sky blue, part E is black, and parts F and G are Color the key card 1 in a dark brown color to camouflage the presence of the color mark. In addition, the color marks 1a to 1h as shown in L are similarly displayed on both the front and back sides of the key card 1, and the color marks I i, 1 on the back side of the key card 1 are similar.
j (#31st and l) Conversely, 11 is 'lIj'fJi
J is colored "bright", and when the back of the key card 1 is set to 1- and inserted into the reader 2, the glass frame is unlocked. The frames can be unlocked separately.

Reader 2 Ld, space 2 for inserting the key card 1 behind the slit hole as shown in the cross-sectional view of FIG.
a, and above this plate-shaped space, optical sensors 2b are arranged at positions corresponding to the color marks 1a=1j of the key card 1 as shown in FIG. Optical sensor 2)
) are arranged at predetermined positions, and a light emitting diode and a phototransistor type sensor are used as the sensor 2b. In addition, reader 2
The lower part between the card insertion slit hole and the detection part is open [
-1, so that even if a foreign object is inserted through the card slot 1, it will fall downward and the foreign object will not become clogged.

3 is a control circuit which manually inputs a front frame signal or glass frame signal from the reader 2, inputs a matching signal from a comparator 4 (described later), and unlocks the front frame according to the number of these input signals. It has a structure that outputs unlocking signals for the believer and glass frames to their respective output circuits. This control circuit 3 has a BCD-10
When a decimal decoder is used and a match signal and a front frame signal are input, an unlock signal for the front frame is sent to the output circuit 10,
The output circuit 8 and IO operate to send an unlocking signal for the L-1 glass Azusagawa to the output circuit 8 when the coincidence signal and the glass frame signal are manually input. , for example, a pulse wave with a width of several hundred milliseconds
One X number is outputted to the next stage drive circuits 9 and 11, respectively. Drive circuits 9 and 11 consist of switching circuits such as beams 1/- and transistor caps, and when a one-shot signal is input, switches 1/- etc. are turned on for a short period of time, and the renoids 13 provided in the glass frame unlocking mechanism 12 are activated. Alternatively, they are connected to each other so as to energize a renoid 15 provided in the front frame unlocking mechanism 14.

These reader 2, control path 3, output circuits 8, 10, and drive circuits 9, 11 are installed in each pachinko machine.
I get kicked.

- On the other hand, a comparator 4 and a level regulator 5 are installed at 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 the key signal sent from the reader 2 (indicating the key number of the 2-digit BCD signal 0 to 99, which is composed of the output signals of the eight optical sensors 2b). At the same time, it is connected to manually 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 digital switch, sets a key number, and outputs a key setting signal. In addition, comparator 4
is provided for each pachinko machine, but if each pachinko machine has a common key number, only one setting device 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 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. 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 fever. In addition, when the front frame or glass frame is closed, the front frame unlocking mechanism 14 and the glass frame unlocking mechanism 12 are automatically locked because the respective hooks or hooks of the hooks 11 are biased by coil springs or the like. It is a structure.

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. Then, for example, when the key card 1 has a color pattern as shown in FIG. 3, this pattern is detected by each optical sensor 2b as "bright" and "dark" at a predetermined color mark, and the key number " A key signal indicating "37" is sent from the reader 2 to the comparator 4 as a two-digit BCD signal, and a table frame signal indicating the table frame is sent to the control circuit 3 from the optical sensor 2b that detected the color mark li. . 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, and a one-shot signal is sent from the output circuit 10 to the drive circuit 11. The solenoid 15 is turned on for a certain period of time, thereby energizing the solenoid 15. Then, when the solenoid 15 is released for a moment, the front frame unlocking mechanism 14
The locking hook is removed and the front frame unlocking mechanism 14 becomes unlocked, but the release of the locking hook 1F 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 l 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 outputs an unlock signal. is not 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 l is sent from the optical sensor 2b of the reader 2 to the comparator 4, and a glass frame signal is further 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 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 1o.
The relay or switching element of the drive circuit 9 is turned on.

As a result, the solenoid 13 is momentarily turned on, and the solenoid 13 is energized, so that the locking hook of the glass frame unlocking mechanism 12 is released, and the glass frame unlocking mechanism 12 is in the unlocked state. Become. 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 can be opened completely by only momentarily energizing the solenoid 13. Tsuno, key car 1 and 1 are non-11-
If so, the comparator 4 will not output the unlock signal t'', and the solenoid 131 of the glass frame unlocking mechanism I2; l-
It does not work and the lock will not be unlocked.

In this way, the key card 1 has color marks la~],
In other words, it is not affected by magnetism and can be used for a long time. can. Incidentally, by increasing the number of color marks 2-, the key scent V'j of )-amount-1- can be set freely. In addition, when there is an abnormality in which the glass frame material 1: ~ is not input to the same 11ν, the control circuit 3 sends an abnormal signal to the alarm circuit and issues an alarm. You can also rub it regularly. In addition, each solenoid 1/noids 13 and 15 may be provided with a separate circuit that is activated by a manual switch in the event of a circuit failure, or the front frame or glass frame of all pachinko machines must be unlocked. It is also possible to provide a separate circuit for performing the operations sequentially.

<Effects of the Invention> As described in 1-Explanation 1.7 below, according to the unlocking device for a pachinko machine of the present invention, color coding is performed according to the key scent. The key card is inserted into a reader equipped with an optical sensor to read the key half-bow, so it is not affected by magnetism like a magnetic card and has excellent durability. It can be used for a long time,
The circuit for reading the key scent can also be simplified. In addition, we investigated the color pattern of the key number on both sides of the key card, and separated the color marks indicating the front frame and glass frame on the front and back, so you can see how the difference 17 of one key card is included between the front and back. By simply changing the keys, you can unlock the front frame and glass frame of the pachinko machine separately.
