Claims

[Scope of Claim for Utility Model Registration] (1) A time subtraction counter that electrically calculates the move time of each player, a digital display that displays the two move times of the same time subtraction counter, and the move time of the time subtraction counter. A hand time setting means for initially setting the time, and a pair of hand switches located at a remote location that simultaneously stop the subtraction operation of one hand time subtraction counter and simultaneously start the other hand time subtraction counter. A digital hand clock. (2) Two types of time can be set as the initial setting time: waiting time and subsequent countdown time, and when the initial setting time runs out and the time subtraction counter reaches zero, 2. The digital hand clock according to claim 1, wherein each time the hand switch is pressed thereafter, the set countdown time in seconds is initially set in the time subtraction counter. (3) The digital hand clock according to claim 1, wherein when the time remaining on the time subtraction counter reaches zero, an alarm sound indicating that the time has expired is emitted. (4) The digital hand clock according to claim 2, wherein when the time remaining on the time subtraction counter reaches zero, an alarm sound indicating that there is no time left is generated. (5) Claim 2: When the countdown time of the time subtraction counter reaches zero, an alarm sound is generated to notify the user of this.
Or the digital hand clock described in 4. (6) The digital hand clock according to any one of claims 2, 4, and 5, wherein the countdown alarm sound is generated from several tens of seconds to several seconds before the countdown time of the time subtraction counter reaches zero. (7) The digital hand clock according to any one of claims 3 to 6, wherein the alarm sound is a voice. (8) The digital hand clock according to any one of claims 1 to 7, wherein the pair of hand switches and the time subtraction counter are connected by wire. (9) The digital hand clock according to any one of claims 1 to 7, wherein the pair of hand switches and the time subtraction counter are connected wirelessly.
