Abstract
An electric power transmitting device transmits electric energy from one coil to another coil through an inductive coupling therebetween. One of the coils has an end bent in the axial direction of the coil. When the other coil is to be inserted into said one coil, it can be inserted in not only the axial direction of said one coil, but also a direction transverse to the axial direction through the bent end of the coil. Said one of the coils is typically housed in a holder, and the other coil in the grip of a gun-shaped, hand-held bar-code scanner. When the grip is inserted into a groove defined in the holder, the coils are magnetically coupled to each other, thus providing an inductive coupling. The bar-code scanner can easily be placed on and removed from the holder.
