A rotatable PDA for the scan head

Abstract

The invention relates to a rotatable PDA of a scanning head, comprising a rear case, a scanning head, a rear fixing seat of the scanning head, a front frame of the scanning head and a rotating mechanism. A scan head assembly is formed by assembling a scanning head rear fixing base and a scanning head front frame together; The scanning head assembly is located in a second cavity of the rear housing, wherein the projections of the front frame of the scanning head are inserted into the recesses of the second accommodation cavities of the rear housing, The other side of the front frame of the scanning head is connected with the rotating mechanism, the rotating mechanism is fixed in the second cavity of the rear case, the scanning head assembly is protruded from the second window of the rear case by hand and rotated, and the scanning head assembly can rotate in a certain angle under the combined action of the rotating mechanism, the protruding pillar of the front frame of the scanning headand the concave hole of the second cavity of the rear case. The PDA structure of the scanning head which can rotate is simple and reasonable, easy to operate, and the data acquisition can be carried out after the upper and lower scanning angles of the scanning head are adjusted according to different scenes when the scanning head is used.

Description

【Technical field】 [0001] The invention relates to electronic products, in particular to PDA products, in particular to PDA products with a scanning head. 【Background technique】 [0002] Prior art PDA product application is more and more extensive, and PDA is the abbreviation of English " Personal Digital Assistant ", literally means " personal digital assistant ", and what have is called " handheld device ", is also called " palmtop computer "; Classification, divided into industrial-grade PDA and consumer PDA, industrial-grade PDA is mainly used in the industrial field, including barcode scanners, RFID readers and POS machines; consumer PDA includes smart phones, tablet computers and handheld game consoles.
