Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention relates to an unlocking device for a glass frame in a pachinko game table which has excellent operability and high crime prevention effect.

(B) Prior Art As the above-mentioned unlocking device, conventionally, a mechanism has been adopted in which a key body is inserted into a key hole provided on a front side portion of a pachinko game table, rotated, and mechanically unlocked. However, with this method, it is difficult to work quickly and it is easy to duplicate the duplicate key, and if the key is stolen or lost, in order to prevent the key from being used illegally, There was a fatal drawback that the entire set of locks had to be replaced. Therefore, in order to improve those drawbacks, the present inventor first replaced the conventional unlocking mechanism with a practical application.
As shown in No. 9-053698, several N
A lock sensor having a combination of sensing elements of poles and S poles is attached, and a key having the same number of sensing elements of N poles and S poles is brought into contact with the lock sensor to combine the sensing elements of the keys and the lock. We developed an unlocking mechanism that outputs a signal to be unlocked from the lock sensor to the opening / closing device of the glass frame when the combination with the sensing element of the sensor is matched, and was well received.

(C) Problems to be solved by the invention The unlocking mechanism described above is, compared with the conventional mechanical unlocking mechanism,
Even if the operability is improved and the duplicate key is duplicated or stolen, cheating can be prevented by changing the combination of the sensing element and the non-sensing element of the lock sensor, so you can set the key and lock as before. There is no need to replace it. However, when opening the glass frame, the lock sensor does not operate unless the key is held by the hand and accurately touched the lock sensor, so the operability is still complicated and there is room for improvement.

The present invention is an unlocking device developed as a result of earnest research to unlock the locking mechanism of a pachinko glass frame with one touch, by improving the above-described conventional unlocking device. It consists of a master unit that sends a predetermined signal by switch operation and a glass frame unlock command signal when a specific signal is received, and a slave unit that sends a specific signal when the predetermined signal is received. , The wrist mounting means is provided, and in order to further improve the function, the master unit collates the specific signal transmitted from the slave unit with the stored signal set in the master unit, and both signals are Connect the circuit that issues the glass frame unlock command signal only when they match,
Further, the parent device is connected to a terminal device, the operation of the parent device is centrally controlled by the terminal device, and a setting change circuit for a specific or predetermined signal is provided in each of the parent device and the child device.

One master device 1 is attached to each pachinko game table P, all master devices 1 are connected to the terminal device 6 in each block, and the terminal device 6 is connected to the host computer 7 and its host computer. At 7, the master units 1, 1 ... Are centrally managed via the respective terminals 6, 6. The master device 1 has two important functions, and one of them is to transmit a predetermined optical signal from the light projecting element 3 to the slave device 8 by operating the button of the access switch 2. The other is to receive a predetermined optical signal from the slave unit 8 by the light receiving element 4, compare it with the stored identification code, and issue an unlock command signal when both identification codes match. On the other hand, the child device 8 is 40 mm long, 35 mm wide,
It is housed in a case 9 having a height of 20 mm, and a belt type wrist band 10 is attached to the case 9. A communication window 11 for transmitting and receiving signals is provided on the inclined side surface of the case 9, and a light projecting element 12 and a light receiving element 13 are provided inside the communication window 11. Near-infrared LEDs are used for both the light projecting elements of the parent device 1 and the child device 8, a photodiode is used for the light receiving element, and MF is used for communication between the parent device 2 and the child device 8.
The M half-duplex bidirectional communication system is used, and the transmission speed is about 0.5.
Seconds (no retries). It is assumed that a lithium battery is used as the power source of the slave unit 8 and that it is accessed 1000 times a day.
Life expectancy of more than a year is covered.

The cordless handset 8 thus formed is attached to the wrist of the dominant arm using the wristband 10, and the master unit 1 is held by the finger of the dominant arm.
When the access switch 2 of is pressed, a predetermined optical signal is emitted from the light projecting element 3 of the master device 1, and the optical axis of the light projecting element 3 is set downward at 45 degrees at this time, so that the optical path is not changed. The light receiving window 11 of the child device 8 is positioned and the light is received in a natural posture (FIG. 3).

The optical signal emitted from the light projecting element 3 of the master device 1 when the access switch 2 is pressed includes, for example, a key No. determined for each slave device. Hall N decided by each pachinko parlor
o. Included is a predetermined identification code that is symbolized.

An example of communication between the master device 1 and the slave device 8 will be briefly described with reference to FIGS. 5 and 6. When the predetermined optical signal is projected from the light projecting element 3 of the master device 1, this light is emitted. The signal is converted into an electric signal by the photodiode which is the light receiving element 13 through the communication window 11 of the slave unit 8, amplified by the amplifier by the light receiving circuit 14, and then integrated by the detection circuit 15 to be extracted as a predetermined electric signal. This electric signal activates the reset circuit 16 and the data buffer circuit 17, outputs a reset pulse from the reset pulse generation circuit 18 to the one-chip microcomputer 19 to activate the one-chip microcomputer 19, and also causes the data buffer circuit 17 to operate. The stored identification code is output to the one-chip microcomputer 19. Thereby, the identification code included in the optical signal emitted from the light projecting element 3 of the master device 1 by the one-chip microcomputer 19,
The identification code stored in the data buffer circuit 17 is compared, and when the two identification codes match, the one-chip microcomputer 19 activates the light projecting circuit 20 to change another identification code from the near infrared LED which is the light projecting element 12. The optical signal including the light is projected toward the light receiving element 4 of the master device 1 through the communication window 11, and when the identification codes do not match, an optical signal for turning on the external crime prevention output of the master device 1 is emitted to generate the master device. The child device warning lamp 5a, which is one of the display lamp groups 5 provided in No. 1, is turned on.

The master device 1 receives the optical signal including the other identification code as the light receiving element 4
When the light is received at, it is collated with another identification code stored in advance, and if they do not match, the master unit warning lamp 5b is turned on,
If they match, a glass frame unlock command signal is issued and the unlock motor is operated to unlock. When the glass frame is unlocked, the monitor lamp 5c for notifying it is turned on. In addition, in the master unit 1,
The door can be opened illegally by incorporating a door sensor that indicates that the glass frame is closed, a magnet sensor that detects illegal activities using magnetism, and a lighter sensor that detects noise caused by electric discharge generated when the electronic writer is activated. If such a defensive measure is taken and those sensors are activated, the monitor lamps 5d, 5e, 5f of the display lamp group 5 are turned on to prevent fraud. ing. In the device of the above embodiment, the master device is controlled by the terminal device, but it is also possible to incorporate a control function into each master device, and to provide a backup mechanism in the identification code storage circuit part or to identify the master device. It is possible to provide a confirmation function for performing collation again when the codes do not match, and the recognition code can be appropriately rewritten by using a rewriting device (not shown).

As described above, in the device of the present embodiment, the wrist device is attached to the wrist of the dominant arm by using the wrist band, and when the push button of the master device is pushed by the finger of the dominant arm, the projector element of the master device causes the optical path Since the optical axis is provided downward by 45 degrees so that the light receiving element of the slave unit is located in the sub-unit, the unlocking work can be performed in a natural posture, which is ergonomically ideal. The work is extremely simple because it is only a push button operation, and because it is attached to the wrist, there is no risk of loss and both hands can be used freely. Moreover, since the slave unit is designed to activate the one-chip microcomputer after receiving a predetermined signal, it consumes less power and can maintain a long battery life.

In addition to using a wristband of a belt lock, a fitting device having a spring property or a bracelet-like device can be used as a means of attaching the child device to the wrist. It is not limited to the example.
