The utility model 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, main control unit, 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 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, LED lamp illuminates, and meanwhile, utilizes described board by handwriting mode input command, and described main control unit calculates and controls display screen and shows after described order is resolved.
As a kind of optimal technical scheme of the present utility model: also comprise the ultraviolet currency detection lamp being arranged on described housing, described ultraviolet currency detection lamp is connected with power supply.
As a kind of optimal technical scheme of the present utility model: 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 kind of optimal technical scheme of the present utility model: described main control unit is ATCS51 type single-chip microcomputer.
The utility model adopts technique scheme, can produce following technique effect:
The counter that the utility model provides, by set up 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, convenient use, strengthens 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 counter one, accurately quick, improved the security in process of exchange, the practicality of counter has been further enhanced, for user facilitates.For LED lamp, be arranged at the internal layer of described housing; 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 LED lamp to be arranged at surface of shell and too dazzling; the use of obstruction to button, vision protection improves 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.
Accompanying drawing explanation
Fig. 1 is the structure use figure of counter of the present utility model.
Fig. 2 is the schematic diagram of the board of counter of the present utility model while using.
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, embodiment of the present utility model is described.
As shown in Figure 1, the utility model provides a kind of counter, comprise housing 1, power supply, push-button unit, main control unit, display screen 2, wherein push-button unit, main control unit, 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 meanwhile, utilizes described board 6 by handwriting mode input command, and described main control unit calculates and controls display screen 2 and shows after described order is resolved.
