摘要 | PURPOSE: A counter is provided to count the number of goods, specially to prevent malfunction, to elongate a life span, to simplify the structure, to reduce manufacturing processes, and to reduce a manufacturing cost. CONSTITUTION: The apparatus comprises a display(2), a micro-computer(1), an up counting module(3), a down counting module(4), a reset key(5), an external signal counting key(6), and a limit switch(60). The up counting module(3), the down counting module(4), and the reset key(5) are installed at the micro-computer(1). The external signal counting key(6), installed in parallel with the up counting module(3), includes various input devices. The external signal counting key(6) is detachable to a main body by forming a connector hole(61) at the main body, and includes a jack(62) at one end for being inserted into the connector hole(61). In the case of an up counting process, the goods touch the up counting module(3), and the touch number is displayed on the display(2), and in the case of a down counting process, the goods touch the down counting module(4), and the touch number is displayed on the display(2). In the case of counting the number of repeated actuation in a machinery, the jack(62) gets inserted into the connector hole(61), and the limit switch(60) gets installed at a proper position of the machinery. According to the repeated actuation of the machinery, the limit switch(60) transmits signals to the micro-computer(1) and the micro-computer(1) displays the counting number on the display(2). | ||||||
