Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security system in a pachinko amusement park, and more particularly to a security system using a television camera, which is necessary for crime prevention, theft and other crime prevention in a pachinko amusement park.

[0002]

2. Description of the Related Art Conventionally, as a security system in this kind of pachinko playground, there has been a system shown in FIG. 12, for example. That is, a plurality of remotely operable movable preset cameras 1C and ordinary television cameras 1
D is appropriately placed in the monitoring place, and this is input to the image distributor 14, which is then connected to the camera sequencer interface 4A.
Alternatively, it is distributed and output to the four-division unit 15A.

The four-division unit 15A has four cameras 1
The image signals sent from C and 1D are displayed by dividing the screen of one whole monitor 8C into four parts. In this example, for example, 16 preset cameras 1C and 8 ordinary TV cameras 1D are displayed. With a total of 24, all four pieces of image information can be displayed by six four-division unit 15A and six total monitors 8C corresponding thereto.

The preset camera 1C is installed in a place with good visibility, such as near the ceiling of a pachinko game hall. The preset camera 1C has a structure that can be rotated up and down, left and right by a remote operation, and can be zoomed, and monitors the inside of a pachinko playground hall or the like by the operation of a monitoring operator.

The image signals sent from the cameras 1C and 1D are also input by the image distributor 14 to each VTR (video deck) 9B determined for each event via the camera sequencer interface 4A. The camera sequencer interface 4A reduces the image from each camera and synthesizes image signals such as split display on one screen.

Of the outputs of each VTR 1 to 4, a part (VTR
1, 2) are image selectors 17 via the image distributor 16.
Alternatively, it is sent to the center controller 11A, and the other part (VTR3, 4) is sent to the image selector 17.
Then, the image selected by the image selector 17 is displayed on the master monitor 8D or the VTR monitor 8E as required.

The center controller 11A displays the above-mentioned image, and also operates the preset camera 1C and an image switching operation by a predetermined console, the control signal is sent to the image distributor 14, and each preset camera is further operated. Sent to 1C.

In this manner, each facility of the pachinko amusement park is photographed by the television camera, and the image signals thereof are switched or combined to efficiently monitor.

[0009]

However, in the monitoring method using the preset camera 1C, a large number of cameras can be used to monitor a wide area, but the preset camera 1C is rotated to perform monitoring. However, it is impossible to monitor the entire monitored place at once, and there is a risk of overlooking misconduct. In addition, even if an abnormality is detected by a sensor or the like, it often takes time to obtain an image of the location, and such a time lag is a major obstacle to prevent fraudulent acts that can only be caught by current offenders. It was

Further, as shown in FIG.
The number of signal cables from E is required to correspond to each camera 1E, and since this is wired to the monitoring unit 30 as it is, the wiring to the monitoring unit 30 becomes complicated, the wiring equipment becomes large, and the cost increases. There was a negative effect of inviting me.

The present invention has been made in view of the above points, and an object thereof is to provide a security system capable of grasping the whole monitored place in real time with a small number of cameras and capable of promptly dealing with an illegal act or the like. Especially.

Another object of the present invention is to reduce the number of cables from each surveillance camera to simplify wiring, save space in wiring equipment, and reduce cost. To provide.

[0013]

In order to achieve the above object, the present invention provides an image of a game machine such as a pachinko machine 10A or a throttle machine and its surroundings, and other equipment such as a currency exchange machine, a medal counter, a ball counter and the like. By monitoring using the camera 1A that takes in and sends out a fixed image signal,
In a security system for fraudulent acts and other crime prevention, a wide-angle lens is used as the lens of the camera 1A, and one camera 1A is used to secure a field of view for two pachinko machines 10A.

Further, a plurality of cameras 1A are connected through a communication unit 2 which selects and switches signals from the cameras 1A by a control signal from the outside.

[0015]

When a part of the mounting work (island) of the pachinko machine 10 is to be monitored by the TV camera 1E having the normal lens, for example, as shown in FIG.
If the camera 1E is installed above 0A, the entire image of the two pachinko machines 10A cannot be monitored because the image area is small. (B) is a view of this state viewed from above.

However, when a wide-angle lens (fisheye lens) is used as the lens of the camera 1A, its field of view is widened, and the camera 1A is installed above the two pachinko machines 10A as shown in FIG. 9 (a). It is possible to monitor the whole even if the is installed. (B) is a view of this state viewed from above.

If a wide-angle (fisheye) lens is used as the lens of the camera 1A, the obtained image will be distorted, unlike the actual image. Therefore, in FIG.
Using the digital memory unit 22 as shown in 1,
Correct the image. That is, the distorted image obtained by the camera 1A is temporarily stored in the image memory 22A in the digital memory unit 22, and here the correction software 22 is used.
The image is corrected to a normal image by B and output to the monitor 8F or the like.

Further, if all the cables from each camera 1A are wired as they are to the monitoring section 30, the wiring material becomes enormous, the wiring space increases, and the cost increases. Therefore, for example, a cable is connected via the communication unit 2 for each mounting work (island) 10 and the number of cables according to the number of image signals required by selecting and switching the image signals by this communication unit 2. Can be reduced to.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to the drawings. 1 to 3 are views showing a security system of a pachinko playground which is an embodiment of the present invention, and FIG. 1 is a view showing a relationship between a base mounting feature (island) of a pachinko base 10 and a camera 1A, FIG. 2 is a diagram showing a communication unit 2 for relaying an image signal from the camera 1A, and FIG. 3 is a diagram showing the overall configuration.

It is a table installation work (island) where multiple machines are installed.

In this example, 16 pachinko machines 10A are installed on one surface of the table mounting feature (island) 10,
The number is not limited, and a number larger than this does not cause a problem at least in practicing the present invention. Further, the table mounting feature (island) 10 is a section in the amusement park in which a plurality of pachinko machines 10A are ordinarily installed with their backs facing each other.
It is designed to store various equipment required for 0A management.

Then, one table-mounting feature (island) 10 and another table-mounting feature (island) 10 serve as a passageway, through which the player moves, and if there is a platform he / she likes, a pachinko machine 1
You can enjoy sitting on a chair installed in front of 0A and operating the pachinko machine 10A.

The camera 1A is installed on the ceiling of the passage.
Is installed, and pachinko machine 10A and pachinko machine 10
It is designed to be installed between A and above the front surface of the pachinko machine 10A at an appropriate position. Therefore, in this example, the number of pachinko machines 10A is 16 per surface of the table mounting feature (island) 10.
Since the number of cameras is one, the number of cameras 1A corresponding to this is eight. And if there is a pachinko machine 10A facing the table-mounting feature (island) 10, the camera 1A is installed in the same manner,
16 cameras for 1 mount installation (island) 1
A will be attached.

The camera 1A is a so-called television camera, which converts an image input through a lens into a predetermined image signal and sends it out on a cable. And this camera 1
The lens A is a wide-angle (fish-eye) lens, and its visual field can accommodate the two pachinko machines 10A and a certain range of the front surface thereof. Therefore, one camera 1A can monitor two pachinko machines 10A and a player using the pachinko machines 10A.

The image signal sent from the camera 1A is sent to the control unit 30 via the communication unit 2. The communication unit 2 switches image signals according to signals from the outside. For example, as shown in FIG. 2, in this example, cables from 16 cameras 1A are connected, and four cables are connected to the control unit 30. By connecting a cable for control signals and switching the image signal according to the signal from the control unit 30, the image signals of the 16 cameras 1A can be handled by the four cables.

In the above example, there are 16 pachinko machines 10A per side of the table mounting feature (island) 10, and the communication unit 2 is provided corresponding to this, but the number of pachinko machines 10A is limited to this. Instead, it is possible to appropriately determine the correspondence relationship between the two depending on the size of the pachinko amusement park, system design requirements, and the like. Further, in this embodiment, the explanation is limited to the pachinko machine, but it can also be used in a game machine provided in a pachinko game hall such as a throttle table under the same condition.

Further, as shown in FIG. 3, each image signal sent from each camera 1A through the communication unit 2 is RF-modulated by the RF modulator 19, and the RF signals are combined and conveyed by one cable. However, it is also possible to distribute this in the monitoring unit 30, perform RF demodulation in the RF demodulator 21, and take out again as an image signal.

Next, the overall configuration of the system of the present invention will be described with reference to FIG. FIG. 4 is a block diagram showing the overall configuration of a monitoring system which is an embodiment of the present invention.

In the drawing, 1A and 1B are cameras, 2 is a communication unit, 3 is a center master unit, 4 is a sequential switcher, 5 is an image synthesizing device, 6 is a digital correction unit, 7 is a video printer,
8A is an overall monitor, B is an alarm monitor, 9A is a VTR which is a recording device, 11 is a center controller equipped with a touch panel CRT, 12 is a remote unit, 13 is a pachinko machine 1A, a game machine of a pachinko playground such as a ball counter. Is a hall computer for managing.

However, each platform installation (island) 10 has 16 pachinko platforms 1A on one side, 32 cameras on both sides, 16 cameras 1A are installed corresponding to this, and two platform installations ( (Island) 10, that is, one communication unit 2 corresponds to 32 cameras 1A. The image signals sent through the four cables via the communication unit 2 are displayed on the entire monitor 8A and are also input to the center master unit 3.

Further, each camera 1B for monitoring other equipment of the pachinko amusement park, such as a money changing machine, a medal counter, a ball coefficient machine, etc., has a sequential switcher 4 respectively.
Are input to the image synthesizing device 5 after selecting and switching only necessary image signals. The image synthesizing device 5 synthesizes the input image signal into one divided screen such as four or eight, and outputs it to the center master unit.

In the center master unit 3, each preset event of the input image signal, for example, a big hit,
The image is distributed for each security and the image signal is sent to each VT.
Send to R9A. It also sends out control signals for the communication unit 2 and the sequential switcher 4.

The output of each VTR 9A is output to the digital correction unit 6 or directly to the alarm monitor 8B. The image obtained from the camera 1A, which is the output of the VTR 9A, is distorted because it is an image through a wide-angle lens, and it is difficult to see as it is. Therefore, a flat image is obtained through the digital correction unit 6. Fix it. However, in order to process all the images, a plurality of digital correction units 6 are required, but from the viewpoint of cost, one unit processes only the required images. If necessary, an unprocessed tape can be set in the VTR 19A for processing.

The output of the digital correction unit 6 is output by a video printer or monitored by an alarm monitor 8B, if necessary. In addition, the digital correction unit 6
Is output to the center controller 11.

The center controller 11 is connected to a hall computer, and receives an instruction to select a video from the hall computer according to the state of the pachinko machine 10A, such as a big hit, a door open, or a security sensor. The center master unit 3 is instructed to select an appropriate image together with a preset image display program. That is, as shown in FIG. 7, the monitor screen 11A displays, for example, a sketch drawing 11a (indicated by an arrow) of an inside of a hall, an image 11b of a place where an alarm is generated, and an operation screen 11c. You can control the system and get the required image immediately.

The center master unit 3 selects an input image and gives necessary instructions to the communication unit 2 and the sequential switcher 4. The remote unit 12 is the center controller 11
This is a device for remotely performing some of the functions of.

In this way, proper monitoring can be performed efficiently and in real time. In addition, as a monitoring target other than the pachinko machine, for example, as shown in FIG. 5, there is a case where a human sensor 22 or a door sensor 23 is mounted in a pachinko game hall to monitor the entrance of a person at night.

As shown in FIG. 6A, the cameras 1B1 and 1B2 are set inside and above the money changer. Then, as shown in FIG. 3B, the face of the person is photographed by the camera 1B2, the hand is photographed by the camera 1B1, the both are synthesized by the image synthesizing device 5, and the recording medium 9C and the monitor 8 are displayed.
By outputting to G, it is possible to monitor the person who has committed the wrongdoing and the act together, which is extremely effective for crime prevention.

[0039]
