Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, a kind of counter is provided, by set up LED lamp and board on counter, can solve the function that illumination is provided automatically under insufficient light, can, in conjunction with the hand-written typing mode of board, avoid the problem of easily makeing mistakes of keyboard, therefore again, improve counting yield, the convenient use.
The present invention specifically solves the problems of the technologies described above by the following technical solutions:
A kind of counter, comprise housing, power supply, push-button unit, main control unit, display screen, wherein push-button unit, control module, display screen connect successively, also comprise switch, LED lamp, for the board of electronic pen input, one end of wherein said switch is connected with power supply, and the other end of switch is connected with the LED lamp; A side at described housing is provided with the groove of placing board, and described board is connected with main control unit by circuit; After described switch closure, the LED lamp illuminates, and simultaneously, utilizes described board by the handwriting mode input command, and described main control unit is resolved rear calculating and controlled display screen described order to be shown.
As a preferred technical solution of the present invention: also comprise the ultraviolet currency detection lamp be arranged on described housing, described ultraviolet currency detection lamp is connected with power supply.
As a preferred technical solution of the present invention: described LED lamp is arranged at the internal layer of described housing, and the mark part of described push-button unit is that transparent material is made.
As a preferred technical solution of the present invention: described main control unit is ATCS51 type single-chip microcomputer.
The present invention adopts technique scheme, can produce following technique effect:
Counter provided by the invention, by set up the LED lamp on housing, opening switch when needs provide illumination, can complete the function that illumination is provided self, simultaneously, can on board, by electronic pen, manually input instruction, the problem of avoiding button easily to make mistakes, input mode is flexible, can improve the counting yield of counter, the convenient use, strengthen the functional of counter.When carrying out cash settlement, can utilize the ultraviolet currency detection lamp on counter to carry out currency examine, collect currency detection lamp in the counter one, accurately quick, improve the security in the process of exchange, made the practicality of counter be further enhanced, for the user facilitates.Be arranged at the internal layer of described housing for the LED lamp; the mark part of described push-button unit is that transparent material is made; such structure can convenient calculator the mark part of push-button unit form ray structure; when illuminating button; prevent the LED lamp to be arranged at surface of shell and too dazzling; the use of obstruction to button, vision protection is done improvement for the illumination of computing machine again, more reasonable and convenient.Main control unit is ATCS51 type single-chip microcomputer, can reduce costs, and improves travelling speed, makes the calculating of counter more accurate.Therefore, this counter can better be used by people.
The accompanying drawing explanation
The structure use figure that Fig. 1 is counter of the present invention.
The schematic diagram when board that Fig. 2 is counter of the present invention is used.
Wherein label is explained: 1-housing, 2-display screen, 3-LED lamp, 4-switch, 5-groove, 6-board, 7-ultraviolet currency detection lamp.
Embodiment
below in conjunction with Figure of description, embodiments of the present invention are described.
As shown in Figure 1, the invention provides a kind of counter, comprise housing 1, power supply, push-button unit, main control unit, display screen 2, wherein push-button unit, control module, display screen 2 connect successively, also comprise switch 4, LED lamp 3, for the board 6 of electronic pen input, one end of wherein said switch 4 is connected with power supply, and the other end of switch 4 is connected with LED lamp 3; A side at described housing 1 is provided with the groove 5 of placing board 6, and described board 6 is connected with main control unit by circuit; After described switch 4 is closed, LED lamp 3 illuminates, and simultaneously, utilizes described board 6 by the handwriting mode input command, and described main control unit is resolved rear calculating to described order and controlled display screen 2 to be shown.
In the cash settlement process, can also comprise the ultraviolet currency detection lamp 7 be arranged on described housing 1, ultraviolet currency detection lamp 7 is connected with power supply, by ultraviolet currency detection lamp 7, helps currency examine.
