Abstract
In order to alleviate condensation which can cause window fogging or frosting conditions when the scanner is used in frigid environments as in refrigerated warehouses, a holder for the scanner is provided which may be located on a forklift or at a strategic location where rapid temperature changes can occur. The holder defines a chamber having doors defined by brushes which contact each other and which are located at one end and across at least a part of the bottom of a housing providing the chamber. The bar code scanner has a head and a handle which may be inserted through the end door into the chamber and supported by a shoulder surface of the bottom of the head around the handle. The doors seal the chamber while having sufficient permeability to allow the escape of moisture. The inside of the chamber may be heated to a temperature which alleviates any fogging. The operator may insert the scanner into the holder from time to time to alleviate condensation, fogging or frost formation and to maintain the scanner in its temperature operating range.
