Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an abnormality detection device for a pachinko ball rental machine that rents out pachinko balls.

(Prior art) An intermission ball lending machine (hereinafter referred to as a ball lending machine) generates a fin insertion signal to the hall combinator every time a spectator inserts a coin, and this two coin tossing signal generator and a computer communicate the signal. If the connector is accidentally disconnected by the pachinko clerk, the ball lending will be performed normally, but the computer will not be able to input the coin. Therefore, even if the connector was removed in advance and the store was opened illegally, the store would not be aware of the act and this would cause an abnormality in sales.

Against this background, devices that only detect an abnormality when the signal line connector is removed have also been provided. (Problem to be solved by the invention) If an accident occurs in which the pulse signal corresponding to the coin inserted into the lending machine is not received by the hall computer due to some abnormality (especially if the connector of the transmission cable is disconnected), the playing machine will be stopped and the coin inserted will not be received. A circuit is installed that detects accidents such as short circuits and malfunctions caused by the balls being removed before they reach the safe where they are to be collected, and stops the pachinko ball rental machine from renting balls, and displays a predetermined message on the display of the machine. The purpose of the present invention is to provide an abnormality detection device for a pachinko ball rental machine that is novel and unprecedented.
