Electric power transmitting device with inductive coupling

A manually operable device and holder combination comprising:

• a manually operable device;
• a first coil disposed in said manually operable device;
• a secondary battery disposed in said manually operable device and electrically chargeable by an electric current induced across said first coil;
• a holder for holding said manually operable device;
• means defining a groove in said holder, said manually operable device being insertable into said groove in two substantially perpendicular directions;
• a second coil disposed in said holder along said groove, said second coil having a bent portion extending transversely around said groove, said bent portion being bent in one of said two substantially perpendicular directions;
• and
• an electric power transmitter for supplying said second coil with an electric current which varies in magnitude with time.

A hand-held bar-code scanner and holder combination comprising:

• a gun-shaped hand-held bar-code scanner having a grip;
• a first coil disposed in said grip of the bar-code scanner;
• a secondary battery disposed in said bar-code scanner and electrically chargeable by an electric current induced across said first coil;
• a holder having a groove therein for holding said grip of the bar-code scanner,
• said grip of the bar-code scanner being insertable into said groove in at least two substantially perpendicular directions;
• a second coil disposed in said holder along said groove, said second coil having a bent portion extending transversely around said groove, said first and second coils being positioned in substantially one plane when said grip is received in said groove;
• and
• an electric power transmitter for supplying said second coil with an electric current which varies in magnitude with time.
