[Problems to be solved by the invention] However, conventional vending machines require high electricity costs, and some stores where vending machines are installed do not use lighting lights due to the W1 layer. In some places, the lights are turned off arbitrarily. However, if the lights are turned off more than necessary, there is a problem in that the effect of displaying products will be diminished and sales will be adversely affected.

Another problem with illumination lights is that they are either turned off or turned on, and the brightness cannot be changed.

Step 81. The first contact 4 and the second contact 5 are operated by the output command signal of the discrimination circuit 2, and the illumination lamp 7 is controlled.

Also, each time the clock IC ticks, the CPU
outputs a signal to turn off the fluorescent lamp 9 or turn it on or dim it.

At 8 p.m., the electromagnetic solenoid is energized, the gear mechanism is switched to normal rotation, the drive motor is rotated for a certain period of time, the variable resistor is rotated through a certain angle, and then the drive motor is stopped. Next, turn on relay Y6 and turn on dimmer.
NL...Next, relay X is demagnetized and contact XA is turned OFF to dim the fluorescent lamp 6 by 90%.

Next, at 10 p.m., the drive motor is rotated for a certain period of time, the variable resistor is rotated by a certain angle, and then stopped to dim the fluorescent light to 70%.

Then, at 3 a.m., the electromagnetic solenoid is demagnetized, the gear mechanism is switched to reverse, the drive motor is rotated for a certain period of time, then stopped, and the fluorescent light is dimmed to 90%.

Next, at 5 a.m., relay X is energized, contact XA is turned on, relay Y is demagnetized, contact YA is turned off, the dimmer is turned off, and the fluorescent lamp is turned on.

Then, in step 39, the timer is reset and the process returns to step 34. If it is determined in step 37 that a certain period of time has not elapsed, it is checked in step 40 whether the light receiving device is ON, and if it is ON, the process proceeds to step 42. Next, in step 36, it is checked whether the duty is greater than the maximum value, and if YES, then in step 41, the light receiving device is turned on when the outside brightness exceeds a predetermined level, so it is checked whether the light receiving device is turned on.

If N, proceed to step 42. So step 42
The duty is decreased at regular intervals to gradually dim the fluorescent lamp 35, and then, in step 43, it is confirmed whether the duty is the minimum setting value, and when it reaches the minimum setting value, the output of the duty conversion device is turned off in step 48. Then, in step 49, the fluorescent lamp 35 is turned off, and the process returns to step 31. If it is determined in step 43 that the value is not below the minimum set value, then in step 44 the duty conversion device outputs an output, in step 45 the fluorescent lamp 35 is turned on, and in step 46 it is checked whether a certain period of time has elapsed. If so, the timer is reset in step 47 and the timer is reset in step 42.
