Referring to fig. 1 to 3, for an embodiment of the present invention, a handwriting pad with a code scanning function is introduced, which includes a handwriting pad body 1, and a code scanning module 2 fixedly connected to the handwriting pad body 1. Specifically, a paper placing area is arranged on the handwriting board body 1; the code scanning module 2 comprises a containing body and a scanning assembly arranged in the containing body, wherein the scanning assembly is divided into a light source, a lens 24 and a sensing device, and the lens 24 is arranged in a manner of inclining to a horizontal plane; the sensing device is located above the lens 24 and in line with the major axis of the lens 24. Specifically, the sensing means employs a linear sensor 25; meanwhile, the light source is arranged above the inclined right side of the lens 24, and the light source and the linear sensor 25 are separated at intervals, so that the overall installation height of the scanning assembly can be better reduced, and the occupied space is saved. Further, the light source of the present embodiment employs an infrared lamp 26.
According to the handwriting board with the code scanning function, the scanning module is fixed on the handwriting board body 1 and comprises the scanning assembly and the accommodating body, and the scanning assembly is arranged in the accommodating body, so that the scanning assembly is prevented from being invaded by dust, external light can be effectively shielded, and the scanning assembly is protected from being easily damaged; and the sensing device of the scanning assembly is positioned on the straight line where the main shaft of the lens 24 is positioned, light rays emitted by the light source irradiate on the paper, and the codes are reflected, so that the light rays can be collected to the sensing device through the lens 24.
Specifically, as shown in fig. 3, in the present embodiment, the infrared lamp 26, the lens 24, and the linear sensor 25 are all mounted on a circuit board 21, and the circuit board 21 and the tablet body 1 are electrically connected through a connection wire. Further, the lens 24 is fixed on the circuit board 21 by a positioning mechanism, the positioning mechanism includes a positioning upper shell 271 and a positioning lower shell 272 which are clamped together, and both ends of the positioning upper shell are respectively bolted with fasteners to fix the positioning upper shell on the circuit board 21.
Referring to fig. 2, in the present embodiment, the accommodating body includes a supporting portion 22 and an upper cover 23 covering the supporting portion 22, a cavity for placing the circuit board 21 is formed between the supporting portion 22 and the upper cover 23, and the supporting portion 22 is fixed to the tablet body 1 by screws. The circuit board 21 that the scanning subassembly will be installed to the upper cover 23 covers, can not only protect scanning subassembly and circuit board 21 not receive external influence to suffer destruction, ensures the normal operating of scanning function, can also shelter from external light, avoids external infrared light's reflection to going on of lens 24 interference identification. Since the inclination angle of the lens 24 and the convergence point of the light are very important, the reflection angle is equal to the incident angle according to the optical characteristics, the light emitted from the infrared lamp is reflected by the paper and enters the lens 24, and the linear sensor 25 senses the signal received by the lens 24. Whether the angle of the incident light changes or the tilt angle of the lens 24 changes, the signal received by the linear sensor 25 is affected, and the recognition effect is affected. Under the protection of the upper cover 23, the lens 24 with the fixed inclination angle can keep the angle stable, thereby ensuring that the linear sensor 25 can normally receive signals.
In this embodiment, specifically, a paper fixing clip 3 is installed on the handwriting board body 1, and the paper fixing clip 3 is fixed at the edge of the handwriting board body 1 on the left side of the paper placing area; as the preferred, sweep a yard module 2 setting in the side of paper fixation clamp 3, so set up, make the barcode region on the paper with by the realization of the fixed region of paper fixation clamp 3 centre gripping hug closely, guaranteed better sweep yard in-process barcode region position difficult because of external disturbance aversion, guarantee to sweep the going on smoothly of sign indicating number.
The disclosed handwriting pad of sign indicating number function is swept in area of this embodiment, its paper that can be used to discernment, the bar code is printed out at certain regional position of paper to the ordinary printer that only needs, can realize distinguishing of identity through sweeping code module 2 on this handwriting pad body 1, need not other special tools etc. and it is very convenient to use.
Naturally, the invention is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the invention, and such equivalent modifications or substitutions are included in the scope of the claims of the present application.
