Abstract
A hand held data entry apparatus having a body for receiving, storing and transmitting information, including a camming mechanism for quickly sealingly attaching an accessory such as a scanner to the top of a hand held data entry apparatus. Additionally, a similar camming mechanism is utilized to hold a battery pack in place with the additional feature of not only pulling the battery pack securely against the housing, but also pushing the battery pack contacts into abutment with complementary contacts disposed within the housing. A keypad is provided for permitting information to be manually entered into the hand held body and this keypad is encased in a layer of elastomeric material such as silicone. A pair of LED's are utilized, one to indicate a "good scan" and the other to indicate something else, such as a "bad scan." Additionally, these LED's can be encased in operative or dummy keys in order to save keyboard space. A mechanism is provided for pivoting the scanner about either of two perpendicular axes.
