Abstract

The invention relates to an antenna, particularly to an antenna device for portable data acquisition terminals. The antenna device for portable data acquisition terminals comprises a card reading coil arranged in the case of a top reading head connected to one end of a pull rod, the other end of the pull rod is connected to a handle provided with a card reading circuit, the pull rod is provided with a wire connecting the card reading coil and the card reading circuit, the card reading circuit is connected to a plug through a data wire. According to the invention, the acquisition of distant articles is convenient, the inference from surrounding conductors and circuits in the acquisition terminal is reduced, the reading distance is increased, and the reading performance is improved. Besides, the device has telescopic function, is portable and suitable for miniaturization of portable data acquisition terminals.

Description

technical field [0001] The invention relates to an antenna, in particular to an antenna device for a portable data collection terminal. Background technique [0002] Generally, a "portable data collection terminal" is a portable data collection device that enables its users to communicate in a wired or wireless manner. Such portable data collection terminals tend to be smaller and lighter to provide portability, and their functions are rapidly diversified to meet the needs of various environments. [0003] At present, the existing portable data collection terminals on the market can be divided into straight type, clamshell type and folding type. A clamshell part is rotatably connected to the casing, and the foldable portable data collection terminal includes a straight casing and a folding part that is rotatably connected to the casing in a foldable manner. [0004] Various portable data acquisition terminals usually have antenna devices to ensure reading efficiency and be...
