Abstract
The control system for a vending machine according to the invention is designed for preventing shortage of change coins to a maximum possible extent. According to the control system, as many coins of a low denomination as possible among coins inserted by a purchaser are collected for use as change coins. The control system further includes, in addition to main tubes to which inserted coins are automatically supplemented, auxiliary tubes to which coins are manually supplemented by a supervisor of the vending machine. A payout control between the main tubes and the auxiliary tubes is effected without providing a special switch for detecting change over between the main tubes and the auxiliary tubes.
