PURPOSE:To attain a small-sized system and to improve the reliability, by dispersedly providing a low-voltage converting circuit on the same board as a circuit board and arranging the circuit in the vicinity of said board in accordance with the required current capacity of circuit board groups. CONSTITUTION:A power supply printed board 10 consists of a low-voltage converting circuit and have a small current capacity split into required numbers. The power consumption of a circuit board group 2 stored is split, and in accordance with the divided power consumption, the printed board 10 is divided into, e.g., three as shown in a figure and the divided boards are arranged on the same board as the circuit board 2. Each power supply printed board 10 and a power reception section 4 are connected with cables 11 and power is supplied at a high voltage. Thus, a small-sized system can be attained and the reliability can be improved. |
