AUTOMATIC VENDING MACHINE

摘要

PURPOSE: To arbitrarily set a threshold value for performing comparison with output signals from a light receiving circuit for detecting lightness around an automatic vending machine and controlling an illuminating lamp by a remote controller. CONSTITUTION: In a storage means inside a microcomputer 1 which is the control means of this automatic vending machine, the threshold value to be compared with the output voltage Vs of the light receiving circuit 2 for detecting the surrounding lightness is set corresponding to the conditions of an installation place by the remote controller 5 disposed on the back side of a main door. The microcomputer 1 controls the lighting and turning off of a first fluorescent lamp 6, a second fluorescent lamp 7 and a third fluorescent lamp 8 which are illumination for back light by referring to the output voltage Vs and comparing it with the threshold value stored in the storage means.
