Description

Brief scientific calculator

Technical field:

The utility model relates to the counter technical field, relates in particular to a kind of brief scientific calculator.

Background technology:

In daily life work, counter is one of indispensable office appliance.Particularly aspect financial, calculate owing to often need carry out a large amount of accounts, so general financial staff can have one or more counter.At present, mainly containing three kinds of counters on the market, is respectively simple computation device, scientific calculator, program counter.

Scientific calculator is used for complex calculations such as power, evolution, index, logarithm, trigonometric function more, and the number of keys on its keyboard is more, is divided into button commonly used and the less button of using.But, the existing scientific counter, for easy to use, its button commonly used and less front face area with button all are provided with greatlyyer, and the key arrangement on the keyboard is not compact, causes the volume of scientific calculator bigger, is not easy to carry.

The utility model content:

The purpose of this utility model is to provide a kind of volume less, portable brief scientific calculator at the deficiencies in the prior art.

The purpose of this utility model realizes by following technical measures:

A kind of brief scientific calculator, it includes housing, and housing is provided with display screen, button commonly used, the less button of using, and the described less front face area of button of using is less than button commonly used.

Described button commonly used and lessly all be arranged with button.

Described button commonly used and lessly be circle with button.

Described housing is provided with the direction button.

Described direction button is four, and the four direction button is ellipticity and arranges.

Described housing is provided with solar powered module.

Described housing is snapped with loam cake.

The both sides of described housing offer draw-in groove, and loam cake forms rectangular with draw-in groove coupling.

But described display screen is the LCDs that duplicate rows shows.

The utility model beneficial effect is:

The utility model includes housing, and housing is provided with display screen, button commonly used, the less button of using, and the less front face area of button of using is less than button commonly used; Because less front face area with button is provided with lessly, can reduce the volume of scientific calculator integral body, and the front face area of button commonly used is provided with greatlyyer, can not influence the use of scientific calculator substantially, promptly the utlity model has little, the portable characteristics of volume.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, shown in Fig. 1～6, a kind of brief scientific calculator that the utility model provides includes housing 1, housing 1 is rectangular-shaped, housing 1 is provided with display screen 2, button 3 commonly used, less with button 4, the less front face area of using button 4 is less than button 3 commonly used, and promptly less front face area with button 4 is provided with lessly, the front face area of button 3 commonly used is provided with greatlyyer.In use,,, can reduce the volume of scientific calculator integral body, reach portable purpose so less front face area with button 4 is provided with lessly because less utilization rate with button 4 is lower usually; Simultaneously, the utilization rate of button 3 commonly used is higher usually, so the front face area of button 3 commonly used is provided with greatlyyer, to avoid influencing the use of scientific calculator.

The button commonly used 3 of present embodiment and lessly all be arranged with button 4, so that it arranges compactness more, and button commonly used 3 is arranged with button 4 separation region with less, lessly is positioned at the upper half part in housing 1 front with button 4, uses the lower portion that button 3 is positioned at housing 1 front always; Wherein, button 3 commonly used and lessly be circle with button 4, certainly, button 3 commonly used and less usefulness button 4 also can be not limited to circle for other shape.

The housing 1 of present embodiment is provided with direction button 5, and direction button 5 is four, and four direction button 5 is ellipticity to be arranged, the same compactness of arranging.

The housing 1 of present embodiment is provided with solar powered module 6, and solar powered module 6 to save electric energy, increases the serviceable life of main battery as the auxiliary power supply of main battery in the housing 1.

The housing 1 of present embodiment is snapped with loam cake 7, and wherein, the both sides of housing 1 offer draw-in groove 11, and loam cake 7 forms rectangular 71 with draw-in groove 11 coupling, makes loam cake 7 to snap onto in the draw-in groove 11 of housing 1 by rectangular 71 and fixes; When loam cake 7 snapped onto housing 1 positive, it had the dustproof effect that waits, and when loam cake 7 snapped onto the back side of housing 1, it had the effect of backing plate.

But the display screen 2 of present embodiment is the LCDs (LCD) that duplicate rows shows, first row of LCDs shows the numeral and the functional symbol of input, second row shows result of calculation, this makes the user can know clearly numeral and functional symbol that oneself is imported, and, when finding input error, also can make amendment, thereby effectively improve the accuracy of input.

In sum, the front face area of the utility model button 3 commonly used is provided with greatlyyer, substantially can not influence the use of scientific calculator, and the less front face area with button 4 of the utility model is provided with lessly, and button 3 commonly used and less compact with button 4 arrangements, the volume that this can reduce scientific calculator integral body makes that scientific calculator is easy to carry more, structural reduction.

Should be noted that at last; above embodiment is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
