Abstract
PURPOSE:To make the considerable saving of the space for a control board possible by providing a delay line for preventing chattering for a switch for detecting the positions of conveying articles on a line side. CONSTITUTION:A delay circuit for preventing chattering which is normally disposed on a control board which performs centralized monitoring of articles by detecting the positions of the articles on a line is shifted to the position detecting part provided on the line side. For example, a time off delay circuit consisting of a series circuit of a parallel circuit of an electrolytic capacitor 4 and a relay 5 and a resistance 6 is connected in series to lead switch contacts 2 and normally opened contacts 5a of a relay 5 are connected to the output lead wire 3 of the contacts 2. When the lead switch is closed once, electric charging is effected in said capacitor and therefore, even in the next open state, the contacts 5a are held closed for a constant time by the charging current, by which the chattering of the output signal is prevented and further since these circuits are disposed on the line side, the space of the switchboard is saved.
