Portable document holder

Abstract

A portable document holder for use with an electronic device includes a supporting body, a first retractable mechanism, a holder body and a second retractable mechanism. The first retractable mechanism is connected to the supporting body and movable forwardly or backwardly in a first horizontal direction. The holder body has a bottom pivotally coupled to the supporting body such that the holder body is rotatable in either a clockwise or anti-clockwise direction and a shooting angle is defined between the holder body and a lens module of the electronic device. The second retractable mechanism includes an extension arm coupled to an upper edge of the holder body and two extension arms disposed at bilateral sides of the holder body. A holding space of the holder body is expanded in a vertical direction and/or a second horizontal direction when the extension arms are extended.
