It is an object of the present invention to provide a power supply device that is able to be used even when power is supplied to electronic circuits using secondary batteries of nickel-cadmium batteries and nickel-hydrogen batteries or the like whose recharging capacities are lowered, wherein original performance of the secondary battery can be maintained. A power supply circuit (1) according to the present invention includes a connector (2) which is electrically connected to a secondary battery (3) which is a storage, a voltage step-up circuit (4) that steps up an output voltage from the secondary battery (3), and a power supply line (5) for supplying the stepped-up output voltage to an electronic circuit (11).
L'invention porte sur une alimentation électrique pour circuits électroniques à base d'accumulateurs du type nickel-cadmium, nickel hydrogène ou autres, en maintenant les performances originales, même lorsque leur capacité de recharge est affaiblie. Les circuits (1) de ladite alimentation comportent un connecteur (2) relié à l'accumulateur (3), un circuit (4) élévateur de la tension de l'accumulateur (3), et une ligne d'alimentation (5) fournissant la tension élevée à un circuit électronique (11).
