A gaming machine includes: a power source unit; a game control device; a reporting device; a first temperature sensor provided to the power source unit, which monitors whether the temperature of the power source unit is at or higher than a first threshold temperature; a second temperature sensor provided to the power source unit, which monitors whether the temperature of the power source unit is at or higher than a second threshold temperature higher than the first threshold temperature; and a power control device which performs an abnormal-situation process which causes the reporting device to inform the occurrence of an abnormal situation, when the temperature of the power source unit is at or higher than the first threshold temperature, and perform a power-supply stopping process which stops power supply to the devices, when the temperature of the power source unit is at or higher than the second threshold temperature.

The present invention is a rubber composition for tire treads, of which the temperature of the peak position of the temperature curve of tan &#x3b4; is &#x2212;16.0&#xb0; C. or higher and &#x2212;6.0&#xb0; C. or lower, tan &#x3b4; at the peak position is larger than 1.13, tan &#x3b4; at 0&#xb0; C. is 0.95 or more, and the value obtained by dividing the absolute value of the difference between tan &#x3b4; at &#x2212;5&#xb0; C. and tan &#x3b4; at 5&#xb0; C. by the temperature difference between &#x2212;5&#xb0; C. and 5&#xb0; C. {|(tan &#x3b4; at &#x2212;5&#xb0; C.)&#x2212;(tan &#x3b4; at 5&#xb0; C.)|/10} (/&#xb0; C.) is smaller than 0.045/&#xb0; C. The invention provides the rubber compositions for tire treads that more highly satisfy both low-heat-generation property and wet braking performance.

A cord for reinforcing rubber articles according to the present invention is formed by a thread with ply-twisted cellulose fiber twisted with a thread of ply-twisted nylon fiber. The ply twist number of the nylon fiber is less than the ply twist number of the cellulose fiber. A pneumatic tire according to the present invention uses the cord for reinforcing rubber articles according to the present invention in a ply cord of the carcass.
