Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
245 words
An apparatus for selectively counting events or timing elapsed time comprising: an elongated case configured and sized to be manually held by a person during use of the apparatus; means including an actuatable push-button switch at one end portion of said case for developing a count signal in response to each depression of said push-button switch; means within said case including an oscillator for developing continuous time signals at a frequency suitable for use as a time base; switching means mounted on said case for selectively alternatively switching the count and time signals to a common output terminal; and means within said case connected to said output terminal and responsive to count signals applied to said output terminal for counting the same and providing a corresponding numerical indication of the cumulative number count and responsive to time signals applied to said output terminal for counting the same and providing a corresponding numerical indication of the elapsed time count, said means for providing a numerical indication of the number count and elapsed time count comprising a plurality of indicators disposed about the periphery of said case, and said means for counting the count and time signals comprising a plurality of serially connected decimal counters, and a plurality of drivers each connected to receive the output of respective ones of said decimal counters and operative to generate driving signals corresponding to the outputs of the decimal counters and apply the driving signals to said plurality of indicators.
Claim 2
Independent Claim
245 words
