Abstract
The utility model relates to a double print calculator, comprising a printer and a first LCD display screen, a second LCD display screen arranged on the shell of the calculator, wherein the second LCD display screen circuit is connected with the display output circuit of the calculator. When using the calculator, all the customers located in front end and back end of the calculator can see the ongoing calculate action cycle respectively through the first LCD display screen and the second LCD display screen, thus the utility model is convenient to be used.
Description
Technical field
The utility model relates to a kind of counter, particularly the double screen printing computer.
Background technology
Present printing computer generally all comprises printer, counter.This printing computer is owing to be convenient for carrying, and price is low, has printing function simultaneously, thereby is widely used in small-sized market cash register and accounts calculating.But because this counter includes only a LCD display, when carrying out calculating operation, have only operator can see computation process in the face of display screen, and be positioned at display screen back to a side can't see the operation steps of being carried out, have only the printing of from printer, printing after waiting all calculating operations to finish just can find out the calculating operation step that the operator carries out, so just caused and used inconvenience with bar.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provide a kind of from calculating operation person opposite the double screen printing computer by second display screen calculating operation that the person carried out of also seeing the calculating operation.
The purpose of the utility model reality can reach by following measure: this double screen printing computer, comprise the counter that has the printing portion and first LCD display, its special character is: second LCD display is set on the housing of counter, and the described second LCD display circuit is connected in the display output circuit of counter.
Described second LCD display is installed on the front end face of counter.
Described second LCD display is the display output circuit that is connected in parallel in counter with first LCD display.
The utlity model has following advantage: being positioned at the both sides that calculate the counter front and back end can both see the calculating operation process of being carried out by first, second LCD display respectively, the convenient use.
Description of drawings
Fig. 1 is the structural representation of the utility model double screen printing computer.
Fig. 2 is the hardware configuration calcspar of the utility model double screen printing computer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
See also Figure 1 and Figure 2, this double screen printing computer comprises the key groups 1 that is used to import usefulness, the processor 5 that carries out calculation process, to the printer 3 of the operation result printout of processor 5 and first LCD display 2 and second LCD display 4 that input and calculation process result are carried out instant playback.The circuit of key groups 1, printer 3, first LCD display 2 and second LCD display 4 are connected to the input and the output circuit of processor 5.Wherein first LCD display 2 and second LCD display 4 are the display output circuit interfaces that are connected in parallel in processor 5, make the identical unanimity of the shown content of two LCD display, wherein first LCD display is installed on the counter panel up, towards the operator who calculates, second LCD display is arranged at the front end face of counter, the operator who calculates dorsad, and to the angled inclination of the operator's who calculates a side, be convenient to watch.
Double screen printing computer of the present utility model use: the operator who calculates can monitor own calculating operation step of being carried out by first LCD display 2 towards oneself, the opposing party who participate in to calculate then can watch concrete operations step and the content of calculating by second LCD display 4 that is installed on the counter front end face, and needn't wait until that all calculating operations finish the concrete operations step that the printing of being printed from printer 3 back is watched the calculating operation person was carried out with bar.
