摘要

The tennis racquet has an electronic digital clock fitted in to the end of its handle (1). It has a dial showing the hour, minutes and seconds and a press button (9) to make this visible. Another press button can be used to preset the time to be taken for the game and an alarm sounds when the time has elapsed. There is also a dial showing the score in a game. This is in two parts, one showing the points won and one showing the points lost. These are entered by press buttons. A further button serves to reset the scores to zero at the end of the game.
