ABSTRACT:
A marking apparatus in the form of handy and compact writing tool can be used as a marking counter for numerals and quantities, and also used as a stop watch for measuring the time duration in athletic sports or in industrial use. These wide range of applications are enabled by an electronic circuit contained in the apparatus and comprising switches to input marking frequencies, an oscillator generating standard clock pulse signals, counters for counting output signals respectively from the switches and the oscillator, a reset switch for the counters, a toggle switch selectively connecting the marking portion and the oscillator to the counters, segment drivers decoding signals from the counters and driving indicators which display counted values of the counters as figures.
