<p>PURPOSE:To provide a highly reliable automatic starting device of automatic vending machine capable of saving labor and time to be required up to the start of the machine itself by automating complicated occasional setting operation from the completion of assembling up to the start of vending operation and the check of the normality/ubnormality of a control unit. CONSTITUTION:At the time of turning on a power supply, a CPU 1 checks whether valid occational, data are written in an occasional data writing area formed in a RAM 2 or not, and when the data are not written, checks the validity/invalidity of writing and reading operation in/from the RAM 2. When the operation of the RAM 2 is not abnormal, the CPU 1 confirm the check sum of occasional data written in a ROM 3. When the data written in the ROM 3 are not abnormal, the data are read out from the ROM 3 and successively written in the RAM 2.</p> |
