Abstract

PURPOSE: To enable fair countdown, not requiring the help of the 3rd person therefor by a method wherein the arrival at the time limit is informed with an electronic sound by an electronic clock operating in correspondence to a push-button switch and thus the countdown is performed automatically.
CONSTITUTION: The time limit is set by a digital switch 1. When a person on the 2nd move side operates a switch 2 at the start of a game, a green LED 4' lights up and the time in minutes is indicated on an indicator 5'. Then, at the same time when a person on the 1st move side operates a switch 2' with one movein the game, a clock on the 2nd move side, the green LED 4 and an indicator 5 operate and the indicators 5 and 5' indicate the integrated time. When this time approaches the set time limit, for instance, five minutes being left before the time limit, the electronic sound is generated by a buzzer 6, and after arrival at the set time limit, the clock circuit is switched over and the countdown by the corresponding clock is made automatically, while in the indicators 5 and 5' the countdown is made automatically and the indication in seconds is conducted in the indicators corresponding to the operation of the switch 2 or 2'. And, when the countdown exceeds the set time, a corresponding red LED 7 or 7' lights up and the buzzer 6 sounds, whereby the fair countdown is performed, not requiring the 3rd person therefor.
