Title:
DIGITAL REVOLUTION COUNTER
Document Type and Number:
Japanese Patent JPS63121711
Kind Code:
A
Abstract:
PURPOSE:To obtain a revolution counter capable of measuring the number of revolution, a speed, length, time, the number of units, etc., only by itself by inputting the 1st and 2nd position detecting signals to the 1st and 2nd signal inputting means and calculating a value corresponding to a mode by a mode selecting means based on these position signals. CONSTITUTION:A digital revolution counter is used for a measuring instrument for measuring the number of revolution of a motor for driving a belt conveyer, the moving speed of the conveyer, time required for moving a carried substance in a prescribed section, the length of the substance, and the number of substances. Thereby, an input control circuit 3 to which two position detecting signals are inputted, a mode selector 4 consisting of a dip switch and a pulse generator 6 for outputting reference clock pulses with prescribed frequency are connected to the input side of a CPU 5. On the other hand, a reference clock counter 7, an input pulse counter 8 for counting two position detecting signals and a display device 9 for displaying the computed result of the CPU 5 are connected to the output side of the CPU 5 and the CPU 5 regulates an operating state by using a prescale setter 10.
