Abstract

The utility model provides a scanning nib structure, a sensing apparatus and a lens module are positioned in a housing of the nib structure, a through hole is arranged on one end of the housing, a circuit board of the sensing apparatus is provided with a sensing element and a butt joint seat comprising a screw hole, a light-emitting element connected with the circuit board is positioned on a side face of the butt joint seat, a sleeve of the lens module contains a lens inside the sleeve, an interlocking portion of one side of the sleeve is pre-locked in the screw hole of the butt joint seat, a hand tool is utilized to butt joint with a butt joint groove of a rotation portion positioned on the other side of the sleeve, the sleeve is driven to fine adjust and position an image distance, and the image distance is a relative distance between the lens and the sensing element of the circuit board, because the rotation portion is smaller than an external diameter of the sleeve, so whole size of the sleeve can be minimized to cooperate with a shape of the housing, so benefits of simple structure, easy assembling and adjusting, and high structural stability are obtained.

Description

The wand header structure

Technical field

The utility model provides a kind of wand header structure, espespecially enclosure interior is for being positioned with sensing apparatus and lens module, and utilize hand tool to drive in the sleeve of the lens module fine setting location to the relative distance of the sensing element intercropping image distance of lens to the sensing device circuit plate, and can cooperate hull shape to dwindle overall dimensions, and then reach wand header structure simple in structure, that the assembling adjustment is simple and easy and structural stability is high.

Background technology

Progress along with sci-tech product, in the publishing area of language learning, can't reach the function that training is listened in order to break through the hard copy publication, the image that present main mode is the hard copy publication content cooperates CD sheet, VCD sheet or the MP3 etc. that store voice files, but this kind mode reader need to use the part that language learner or computer repeat playing be can not hear clearly, just can reach the immediate interactive effect, cause on the contrary inconvenience in the study.

Thus, a kind of optical point reading pen has just appearred on the market, it utilizes the optical identification technology, when the optical point reading pen point points on the books corresponding by the literal of encoding, during the content such as sentence and picture, can see through the content on the scanning optical lens books, and after reading coding via optical identification, the recycling sound-producing device produces the corresponding sound of pre-recording, thereby realize reading aloud, sounding and translation multilingual, and can repeat to click, repeat-of-pronunciation etc., allow reader's vision and the sense of hearing produce fast and directly interactive, and bring up a kind of the most natural with point with reading mode of learning, improve interest and the effect of study with this.

Yet, commonly use optical point reading pen and often be subject to its inner optical lens and Image sensor apparatus, so that the optical point reading pen external form can't further be dwindled, if the optical point reading pen volume-diminished namely must be considered the problem of overall construction intensity, and because optical lens in the process of making to the image distance between Image sensor apparatus (be on the books content via the distance of optical lens imaging to the optical lens photocentre) location easily produces error, cause Image sensor apparatus function and fiduciary level to reduce, come effectively to be solved and remain to be engaged in this journey dealer design of centre of gravity.

The utility model content

So, utility model people is because above-mentioned problem and the disappearance of commonly using optical point reading pen, be to collect related data via in many ways assessing and consider, and utilize for many years research and development experience of engaging in the industry constantly to study and revise, begin to design the novel birth of this kind wand header structure.

Concrete technical scheme of the present utility model is: a kind of wand header structure is provided, comprise housing, sensing apparatus and lens module, the hollow inside of this housing is formed with the accommodation space that can supply sensing apparatus and lens module location, and is provided with open-work in housing one side place; The circuit board that this sensing apparatus has is provided with a sensing element and has the hollow butt joint base of screw, and that butt joint base covers in sensing element is outside, and is positioned with at least one in the butt joint base side edge and is connected to light-emitting component on the circuit board; This lens module is the sleeve of a hollow, and be formed with the space, location that to accommodate at least one lens in sleeve inner, sleeve one side place then is provided with the lock-joining part of locking in the screw of butt joint base, and the in addition side place of sleeve is provided with turn section, and axially is concaved with in turn section and can drives the docking groove of lens being done the relative distance fine setting location of image distance in sleeve for default hand tool docking.

Utilize said structure in the process of making, to finely tune the location to lens to the relative distance as image distance between sensing element, and because of turn section less than sleeve outer diameter, can cooperate the enclosure interior shape to dwindle overall dimensions, and then reach effectiveness simple in structure, that the assembling adjustment is simple and easy and structural stability is high.
