ABSTRACT:
An enclosure for an electrical data input apparatus which is formed of a top section and a bottom section to form a case. The case has a top section which provides operational access to the electrical data input apparatus, such as a graphics tablet input device, with additional accesses for switching functions, amenable both to right-hand and left-hand use by an operator. The switching function accesses are distinguished one from another by different access hole shapes in order that appropriate switching functions may be effected via those switching function accesses without the necessity of looking away from the computer display and thereby breaking the attention of the operator. Further ergonomic provisions of this enclosure are a stylus which is removably storable within the case, elevation adjustment means by which an operator may adjust the angular attitude of the case with respect to a work surface, and a scribing alignment means which cooperates with scribing guide means in the upper face of the case to enable an operator to record substantially geometrically true inputs on the graphic tablet input device. The scribing alignment means is also removably storable within the case. A further feature of the device is the provision of gripping means on the underside of the case to facilitate hand held operation of the graphic input tablet by an operator.
