OPTICAL EQUIPMENT SYSTEM, OPTICAL EQUIPMENT AND ACCESSORY

摘要

PROBLEM TO BE SOLVED: To solve the problem that the transmission loss of power is large in the conventional power transmitting method of an electromagnetic induction system. SOLUTION: This optical equipment system is composed of optical equipment 1 and an accessory 9 attachable/detachable to/from the optical equipment, and transmits the power or a signal by the electromagnetic induction between the optical equipment and the accessory. In the system, the optical equipment and the accessory are provided with cores 7a and 13a formed of ferromagnetic material and coils 7c and 13c wound round the cores, and both cores are made to abut on each other when the accessory is attached to optical equipment.
