Abstract
PURPOSE: To make possible accurate time indication preventing the uneasiness of control and mishandling by dividing the lap time and the goal time with treatment of the logic circuit.
CONSTITUTION: The stop watch 1 is provided with a display 2, a start-reset-combined control button 4 and control bottons 5 and 6 arranged in terms of the fixed potional relationship. In addition, a logic circuit is arranged inside. Only when the botton 5 is depressed, the switch 7 alone is closed and the output of the NOR circuit 12 goes to the L level. On the other hand, only when the button 6 is depressed, the switch 8 alone is closed and the output of the AND circuit 11 reaches the L level. When both the buttons are depressed simultanelusly, the output of the circuit 11 goes to the H level. Therefore, with the depressing of the button 6, the lap time can be detected while with the simultaneous depressing of the buttons 5 and 6, the goal time can be done.
