Scanning dictionary pen for OCR scanning recognition

Technical Field

The utility model relates to a scanning dictionary pen of OCR scanning discernment.

Background

Existing scan pens typically identify a scan object using OCR scan recognition techniques to read information about the scan object, interpret the contents of the scan object, and so forth.

The conventional wand generally includes a body and an OCR scanning recognition component (see, for example, chinese utility model patent specifications CN 214670508U, CN 214670665U, and CN 216083737U) disposed on a head portion (i.e., a nib) of the body. The OCR scanning recognition assembly comprises a scanning camera, a paper pressing support, an elastic reset element and a position switch, wherein the position switch is provided with a contact which enables the position switch to be in a connection state when being collided, the scanning camera and the position switch are fixedly installed on the head of a pen body, the paper pressing support is installed on the head of the pen body in a front-back sliding mode between an extending position and a retracting position, the paper pressing support collides with the contact of the position switch when being in the retracting position, the paper pressing support is separated from the contact of the position switch when being in the extending position, the scanning camera and the position switch can be simultaneously and electrically connected with a control circuit, the connection control circuit starts the scanning camera when the position switch is in the connection state, and the elastic reset element is arranged between the paper pressing support and the head of the pen body to drive the paper pressing support to return to the extending position. When the paper pressing support is pressed against the paper to be scanned, the paper pressing support is driven to slide to the retracted position, so that the scanning camera is controlled to be opened. When the paper pressing support is separated from the paper, the paper pressing support is reset to the extending position under the action of the elastic reset element, and the scanning camera is closed.

Because the paper pressing bracket needs to slide back and forth, a guide structure is arranged on the pen point to guide the paper pressing bracket to slide. As disclosed in chinese utility model patent specification CN 216352404U, the guide structure of the pen includes a guide block provided at the side of the inching frame (i.e., the paper pressing bracket) and a guide groove provided at the side of the housing (pen head), and the guide is realized by the sliding of the guide block in the guide groove. However, the micro-motion frame of the prior art has the phenomena of side-to-side shaking and loosening, and needs to be improved.

Disclosure of Invention

An object of the utility model is to provide a prevent to press paper support and take place the scanning dictionary pen of OCR scanning recognition that the skew is slack and is collapsed about, including the handwriting and locate the OCR scanning recognition subassembly of handwriting head, this OCR scanning recognition subassembly is including scanning the camera, press the paper support, elasticity reset element and position switch, this position switch has the contact that makes position switch be in the on-state when being collided, this scanning camera and position switch install at the handwriting head fixedly, this pressure paper support is installed at the handwriting head around sliding between an extended position and a retraction position, this pressure paper support is in its contact of collision position switch when being in the retraction position, this pressure paper support leaves position switch's contact when being in the extended position, this elasticity reset element is located and is pressed between paper support and the handwriting to get back to the extended position in order to order about to press the paper support, this handwriting head is equipped with stop gear, this stop gear prevents to press the left and right sides skew of paper support in front and back sliding direction.

The utility model discloses a stop gear who sets up can prevent to press the loose phenomenon of paper support about taking place skew for the structure is compacter.

Detailed Description

The present application is further described below with reference to the accompanying drawings.

A scanning dictionary pen for OCR scanning recognition as shown in fig. 1 to 10 includes a pen body 10 and an OCR scanning recognition module disposed on a head 101 of the pen body, the OCR scanning recognition module includes a scanning camera 20, a paper pressing bracket 30, an elastic reset element 40 and a position switch 50, the position switch 50 has a contact 501 for making the position switch in an on state when being collided, the scanning camera 20 and the position switch 50 are fixedly mounted on the head 101 of the pen body, the paper pressing bracket 30 is slidably mounted on the head 101 of the pen body back and forth between an extended position and a retracted position, the paper pressing bracket 30 collides with the contact 501 of the position switch when being in the retracted position, the paper pressing bracket 30 is separated from the contact 501 of the position switch when being in the extended position, the scanning camera 20 and the position switch 30 can be electrically connected to a control circuit (not shown) at the same time, the control circuit opens the scanning camera 20 when the position switch 30 is in the on state, the elastic reset element 40 is disposed between the paper pressing bracket 30 and the head 101 of the pen body to drive the paper pressing bracket to return to the extended position, the paper pressing bracket 30, the elastic reset element is disposed on both sides of the paper pressing bracket, the paper pressing bracket 101, the compression spring is disposed in the compression mechanism, and the compression spring is disposed in the compression mechanism.

This technical scheme can prevent to press the loose phenomenon that paper support took place left right deviation through the stop gear who sets up for the structure is compacter.

This stop gear includes that two are separated in the piece that presses of pressing the paper support 30 left and right sides, and each presses the piece and presses paper support 30 respectively, and through pressing the left and right sides of paper support spacing with the help of two, its reasonable in design, simple structure is convenient for implement.

Each pressing piece is a screw 60, and the end part of each screw 60 is provided with a hemispherical ball head 601 for pressing the paper pressing bracket 30;

the head 101 of the pen body is provided with a screw hole 102 for each screw 60, the screw 60 is screwed into the screw hole 102, and the ball 601 of the screw extends out of the screw hole 102 and presses against the paper pressing bracket 30.

As the use time increases, the pressing member and the platen holder wear, resulting in loosening (looseness). This technical scheme utilizes the screw and the threaded connection mode realization of screw to press the adjustable of piece, can adjust through adjusting that to press the piece and apply in the pressure of pressing the paper support to practical wearing and tearing.

The two sides of the paper pressing bracket 30 are respectively provided with a groove 301 extending along the front and back sliding direction of the paper pressing bracket;

the ball 601 of the screw on the same side as each recess 301 is recessed into the recess 301. Therefore, the sliding guide of the paper pressing support is realized by utilizing the matching of the ball head and the groove.

The pen body 10 includes an inner casing 103 and an outer cover 104, wherein the two screw holes 102 and the two screws 60 are disposed in the inner casing 103, and the outer cover 104 is detachably covered outside the inner casing 103 to cover the two screw holes 102 and the two screws 60. The technical scheme ensures that the two screw holes and the two screws are covered and sealed in the outer cover, thereby realizing the hiding of the two screw holes and the two screws and leading the appearance structure to be more compact. When the screw needs to be adjusted, the outer cover is opened, and the screw hole and the screw are exposed.

The position switch 50 described in this embodiment may be a microswitch.
