ABSTRACT:
A device resembling a miniature calculator to be worn either on the wrist by a player, or hand-carried by another person, the device having two elongated multiple-digit displays, one for catagorizing and listing points won by the user and the type of shot on which the win was based, and the other for categorizing and listing points lost to the opponent and the type of shots on which the loss was based. The device has a point-WON button and a point-LOST button, which serve to determine which of the two displays will be receiving a point to be newly entered, and the device has a number of additional buttons serving to categorize the type of shot resulting in a won or a lost point. The device can be reset manually, and also has gates which establish a required sequence for pressing the buttons which sequence prevents any accidental double entry of a score either by pressing a button twice or by the bounce of a button's electrical keyboard switch.
