ABSTRACT:
A tape for use in estimating how many electronic parts being fed to an electronic part inserting machine remain on the tqape and a system for using the same. More particularly, a system which counts the remaining electronic parts on the end portion of the tape and sets up a most suitable time that the presently used tape should be replaced with a new one so that the system dead time which may occur during the replacement of tape rolls is remarkably reduced. This tape includes a mark formed at the beginning of an end portion of the tape where some electronic parts are left to be fed to the electronic part inserting machine, and the mark is sensed by a sensor so that the count starts when the end portion of the tape is sensed. The electronic parts inserting machine employing this tape is comprised of a memory for storing a value corresponding to the number of remaining parts attached to the end portion of the tape, a counter for counting down from the number stored in the memory as each remaining part is used, a displayer for displaying the count value generated by the counter, and an CPU for controlling the memory and the counter.
