1. A holder for the reception and selective shielding of an electronic vehicle identifying device, comprising:
- a housing forming a container for the vehicle identifying device, at least a portion of the housing constructed of a shielding material which provides shielding of electronically generated signals, andmanually operable translation means for selectively moving said shielding material portion of the housing between first and second positions relative to the vehicle identifying device, said first position characterized as said shielding material portion overlying the vehicle identifying device to prevent external electronic signal transmission with the vehicle identifying device and said second position displacing said shielding material portion from the vehicle identifying device to permit external electronic signal transmission with the vehicle identifying device.

11. A holder for the reception and selective shielding of an electronic vehicle identifying transmitter, comprising:
-
first and second housing members, said second housing member being a drawer for slidable engagement with said first housing member, said drawer adapted to retain the vehicle identifying transmitter and movable between a first position, substantially completely within said first housing member, and a second position extending outward of said first housing member; at least a portion of said first housing member formed of shielding material to prevent the transmission of electronic signals outward of said holder when said drawer is in its second position, and permitting the transmission of electronic signals outward of said holder when said drawer is in its first position; and means for manually moving said drawer between its first and second positions; whereby the transmission of electronic signals from said holder requires said drawer to be manually moved to its second position. - View Dependent Claims (12, 13, 14, 15)
