An electronic apparatus such as a computer terminal, video camcorder, portable picture phone or a bar code reader includes a display which is arranged to pivot so as to provide optimum ease of viewing for the user. A reader such as an optical scanner for scanning indicia, for example bar code symbols, comprises a handle portion and, mounted pivotally thereon, a head portion. The angle of the head portion relative to the handle portion can be adjusted by rotating the head portion as desired. The reader can thus be used to read bar code symbols that would otherwise be inaccessible. In an alternative embodiment a reading head is mounted pivotally on a fixed terminal and is movable so as to accommodate the physical requirements of the operator.
