Description
Technical field the utility model relates to a kind of computing machine Genius mouse, especially a kind of Genius mouse of tape font code reader functionality.
Bar code reader that background technology is generally used at present and Genius mouse all are two devices independently.Its shortcoming is two independent device cost height, volume is big, mobility is poor, and need take two computer interface resources, and using simultaneously needs conversion mutually, very inconvenient, influences work efficiency.
Utility model content the utility model applying bar code is read chip technology and existing control technique of mouse, and USB control technology, utilize the space of Genius mouse, be embedded in a bar code reading device, make Genius mouse possess the function of bar code reader at Genius mouse.
The utility model is realized by following proposal: the Genius mouse of tape font code read function, it comprises: key, right mouse button, mouse control plate and mouse case in USB interface, connection lead, left mouse button, the mouse.It is characterized in that also comprising in the Genius mouse: bar code reader control circuit board, barcode reading key, read a yard pilot lamp, described bar code reader control circuit board is arranged in the described mouse case, its circuit board comprises: barcode reading circuit, bar code control circuit, USB controller circuitry, power circuit.The barcode reading circuit is selected CMOS barcode reading chip for use, be connected with the bar code control circuit, the bar code control circuit is connected with the USB controller circuitry again, power circuit connects all circuit, corresponding bar code reader place offers the reading window on mouse case, and described barcode reading key is in the Genius mouse left side.
Compare with existing independent bar code reader and Genius mouse, the beneficial effects of the utility model are embodied in following several respects:
1, barcode reading function and mouse function realize that device volume is little in a device, and be simple in structure, easy to install;
2, environmental suitability is strong, and mobility is good;
3, barcode reading transfer rate height;
4, the bar code reader cost is low;
5, support hot plug and plug and play.
Description of drawings Fig. 1 is the schematic appearance of the Genius mouse of tape font code read function; Fig. 2 is the structured flowchart of the mouse of tape font code reader functionality; Fig. 3 is the circuit diagram of mouse controller, and Fig. 4 is the bar code reader circuit theory diagrams.
Embodiment is shown in Figure 1, this device is made up of key 4, left mouse button 5, barcode reading pilot lamp 6, barcode reading key 7, barcode reading window 8 and mouse case 9 in usb 1, connection lead 2, right mouse button 3, the mouse, and the circuit board of bar code reader control circuit board and Genius mouse is arranged in the mouse case 9.Its circuit board comprises: barcode reading circuit, bar code control circuit, USB controller circuitry, power circuit.The barcode reading circuit is selected CMOS barcode reading chip for use, be connected with the bar code control circuit, the bar code control circuit is connected with the USB controller circuitry again, power circuit connects all circuit, corresponding bar code reader place offers the reading window on mouse case, and described barcode reading key is in the Genius mouse left side.
In the such scheme, the USB controller is selected the AN2131USB control chip for use.
With reference to Fig. 4, the output of USB interface is through inductance L 1, L2 and resistance R 1, R2 and USB
With reference to Fig. 4, the output of USB interface is connected with D+, the D-two ends of USB controller through inductance L 1, L2 and resistance R 1, R2, directly is connected with power circuit two input ends through inductance L 3; Power circuit U2 is made up of TPS7333QC chip and resistance R 11, capacitor C 2, C3, and voltage is reduced to+3.3V by+5V; Its output is connected with SCL, SDA, the RESET end of USB controller respectively through resistance R 6, R7, capacitor C 9, and output also is connected with CMOS barcode reading chip MVDDA, Vs through resistance R 3, capacitor C 1, C4.4 output terminals of USB interface mouse control circuit that also is connected in parallel.
Among Fig. 3, Fig. 4, U1 is AN2131; U2 is TPS7333QC; U3 is a COMS bar code acquisition chip; U4 is 74AHC04; U5 is CY7C63000; X1, X2 are 6MHz; C1, C3, C5, C7, C8, C9 are 20u; C2, C4 are 30P; R1, R2, R6, R7 are 100K; R3, R4, R10, R11 are 12k; R5, R7, R8, R9 are 47k.
The course of work of the present utility model is as follows:
A, when the barcode reading instrument by USB interface with after PC connects, according to the WINDOWS plug-and-play feature, bar code reader is by finding driver automatically, and is downloaded among the USB controller U1, loading power is to U2 simultaneously;
B, when driver download finish after, usb bus produces signal resets the U1 secondary, the beginning executive control program;
C, control program receive earlier reads instruction, as press the S key and receive the reading instruction, then the D0-D7 by U1 controls bar code reader U3, and the D0-D7 that passes through U1 reads and writes the internal register of bar code reader U3, finish reading by row to bar code data, by the USB interface (D+, D-) of U1, bar code data is sent on the PC simultaneously.
