Abstract

A casing of a portable data input/transmission apparatus has an end portion, the size of which is determined such that the end portion can be held by one hand. A pen-scanner type bar code reader for reading a bar code is attached to one end of the casing in the longitudinal direction. A keyboard for enabling at least numerical data to be input is attached near the other end of the casing in the longitudinal direction. A transmitter/receiver is stored within the casing, the transmitter/receiver being designed to output wirelessly to an external data processing apparatus code data read by the bar code reader and at least numerical data input from the keyboard. A pair of antenna-containing grooves are formed in a pair of facing side surfaces extending in the longitudinal direction of the casing, such that the grooves extend in the longitudinal direction of the casing to said other end of the casing. An antenna is provided such that it is freely inserted into and drawn from the antenna-containing grooves from the other end of the casing, the antenna being formed of a substantially U-shaped, electrically conductive elastic material and being fitted in the grooves by virtue of the elastic force of the antenna.
