Abstract

PURPOSE:To recharge an electronic clock in short time with low power consumption, by securing a recharging coil onto a coil yoke and constituting a magnetic path with a core of secondary coil and a coil yoke in the electronic clock. CONSTITUTION:Recharging coils 10, 11 are secured onto a yoke coil 12 composed of iron plate or electromagnetic steel plate, and a magnetic path for flux to be produced in the recharging coils 10, 11 is constituted with a core of secondary coil 15 and a yoke coil 12 in an electronic clock 13. Voltage is induced in a secondary coil 14 arranged in the electronic clock 13 by the flux produced in the recharging coils 10, 11 and employed for recharging a secondary cell 17 through a rectifier circuit 16.
