DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a monitoring apparatus in a game hall where a large number of game machines such as slot machines and "pachinko (a Japanese upright pinball game)" machines are disposed in lines.
BACKGROUND ART
A game parlor can suffer losses due to the occurrences of abnormalities and some dishonest game players who commit wrongful acts with the intention of gaining game prizes or the like. In order to cope with the situations, various preventive measures have been proposed (refer to, for example, the official gazette of Japanese Patent Application Laid-open No. 5775/1988).
With a monitoring apparatus hitherto proposed, however, one monitoring video camera is installed for each game machine, resulting in the problem that the installation is costly.
When a plurality of game machines are to be monitored by one monitoring video camera for the purpose of solving the above problem, there is the problem that the image of each monitored game machine blurs, so the wrongful act or the abnormality cannot be satisfactorily observed and dealt with.
DISCLOSURE OF THE INVENTION
The present invention has been made in view of such problems in the prior art, and has for its object to provide a monitoring apparatus in a game hall which can improve the monitored states of individual game machines at a low installation cost.
In order to accomplish such an object, according to the present invention, there is provided a monitoring apparatus in a game hall where a large number of game machines such as slot machines are disposed in lines, characterized by comprising a monitoring video camera which includes a zoom lens, and which is installed at a position for monitoring at least two game machines; preset monitoring condition memories in which preset monitoring conditions of the monitoring video camera for taking a close-up of the each game machine through the zoom lens are respectively stored for the individual game machines; drive means for setting the monitoring video camera according to the preset monitoring conditions; abnormality sensing means for monitoring a game situation; a judgement processor which analyzes information based on the abnormality sensing means, and which, upon deciding that an abnormal state exists, controls the drive means so as to set the monitoring video camera according to the preset monitoring conditions for the game machine corresponding to the abnormal state; and display means for displaying video information of the monitoring video camera on a screen.
Preferably, the apparatus comprises video record means for storing therein the video information on the corresponding game machine, at least when the judgement processor has decided the abnormal state.
Preferably, the judgement processor includes means for actuating the display means to display the machine No. of the corresponding game machine on the screen when the game machine has been specified.
Besides, it is preferable that the display means includes abnormality warning means near the screen, and that the judgement processor includes means for actuating the abnormality warning means to give warning when it has decided the abnormal state.
Further, it is preferable that the judgement processor includes means for actuating the display means to display the machine No. of the corresponding game machine on said screen when it has decided said abnormal state.
While covering the plurality of game machines simultaneously within its visual range, the monitoring video camera is monitoring the individual game machines.
When the judgement processor has decided that there is an abnormal state on the basis of the analysis of the information of the abnormality sensing means, it controls the drive means so as to set the monitoring video camera according to the preset monitoring conditions for the abnormal game machine.
The monitoring video camera takes the close-up of the abnormal game machine through the zoom lens, where-upon an image in which the particular game machine is enlarged and is easy to see is projected on to th
