Below in conjunction with accompanying drawing shown in the embodiment the utility model is described in further detail:

Fig. 1 is the partial cutaway diagrammatic sketch of counter;

Fig. 2 is the panel-shaped synoptic diagram of counter.

With reference to Fig. 1, base plate (1) is provided with some chutes (2), digital bar (3) is embedded in the chute (2) mutually, be marked with numeral at each digital bar (3), the two ends up and down of numeral indicate computing direction prompting symbol, the both sides of digital bar (3) have digital tooth (4), and the spacing of digital tooth (4) is consistent with the spacing of mark numeral.Panel (5) covers on base plate (1).In conjunction with Fig. 2, offer on the panel (5) and dial several mouthfuls (6), dial several mouthfuls (6) left tooth position corresponding to digital bar (3).The both sides of dialling several mouthfuls (6) indicate numeral simultaneously, and the numeral on right side is descending being arranged in order from the top down, and the numeral in left side is ascending being arranged in order from the top down, and its digital spacing is consistent with the spacing of digital tooth (4).Carry seam (7) and borrow seam (8) are arrived at respectively by the right tooth position of round-corner transition to preceding one digit number code-bar in the top and bottom of dialling several mouthfuls (6), reach into one with purpose by means of one.Also be provided with digital display window (9) on the panel (5), the number of digital display window (9) is consistent with the number of dialling several mouthfuls (6).In the assembly of this counter, also be provided with the zero clearing device.The zero clearing device is made up of with nut (11) the zero clearing pull bar (10) of " L " shape.The muscle (12) of chute (2) is controlled the spacing of " L " shape zero clearing bar, makes " 0 " word on the digital bar (3) just in time be positioned at display window (9).The goods and materials label is inserted in the label window (13).

Design concept

On digital bar, in advance that numeral " 9 " is above square digital tooth is made redness (this example has the distance of three teeth because of display window apart from dialling several mouthfuls of lower ends, so redness is set in the 12nd tooth), when digital bar moved down, the pairing position of red tooth also moved down thereupon.First red tooth on the digital bar (counting from lower to upper) constitutes the relation of " 10 " all the time with the numerical value on this group number mouthful right side.For this reason, when ball point pen inserts the digital tooth of any one numerical value of red digital tooth, all represent original numerical value in this input value and the display window and greater than " 10 ", when numerical value just needs carry greater than " 10 ".The design is in the upper end of each group number mouthful, and (R1 equals the radius of ball point pen point to be provided with a circular arc that is joined by R1 and R2; R2 equals adjacent groove width) so that make the backlash of nib rounding off, force digital bar to the carry stop portion of anteposition to move down lattice, to finish carry to the digital bar of adjacent preceding one digit number.

Equally, the numerical value (this example be that redness is digital) in the left side of the pairing a certain group of number of any one white tooth of digital bar mouthful is all greater than the known number in the display window, to from known number, deduct a number bigger than known number, essential will be to anteposition " borrow ", the design equally also designs a circular arc that is joined by R1 and R2 in the lower end of each group number mouthful, so that for the pen that down moves, rounding off is to adjacent digital bar and slide to the borrow seam always, finishes borrow.

No matter be carry or borrow, be restricted to one by " seam " at each group number mouthful two ends.

Method of work:

Addition be ask gained as a result that two or more number merges and.

On the panel of this counter, the set of number on bits per inch right side (representing with black numbers) is the input digit of addend, can adopt the first number with the reading pronunciation to begin during computing, for example 321, can count (by that analogy) from the first place " 3 " of hundred figure places, the ball point pen point is inserted in corresponding figure place and the corresponding digital tooth, and along dialling several mouthfuls to lower slider, at this moment, in panel back, be placed on digital bar in the base plate chute and also follow and move down, when ball point pen moves to when dialling several mouthfuls of lower ends, this moment, digital bar then showed that fenestra demonstrates this reading; When again on this figure place again by above-mentioned action, when importing another numeral, panel reading display window then become two merge numeral and.

When two numbers and during greater than " 10 ", this moment, ball point pen must be to be inserted in the red perforation, so should change traffic direction and along the upper end circular arc, slided to the carry stop portion of adjacent groove by a coherent action, had promptly finished carry.

Subtraction is the poor of deduction one number in a known number.

For this reason, earlier by known number of above-mentioned action input, then, dial the set of number (using red numeral) in several mouthfuls of left sides again by certain one digit number on the panel, ball point pen is inserted in the digital tooth of respective digital, and upwards slide along dialling several mouthfuls, this moment force digital bar also with on move, when moving on to the end on the pen, this moment, the numeral in the display window was then deducted the subtrahend of an input from minuend, and demonstrated poor between them.

When subtrahend during greater than minuend, this moment, ball point pen must be to be inserted in the white perforation, so should change traffic direction, and along the lower end circular arc, slided to the borrow seam of adjacent groove by a sequence, and this has promptly finished borrow.

So operational method can be reduced following some:

1. the The Scarlet Letter in each group number mouthful left side is the input digit that deducts; Dial the numeral on several mouthfuls of right sides, then input digit for increasing.

2. when pen protrudes into red tooth, up move without exception; Adding rule needs to slide to along circular arc the carry seam of carry.

3. when pen protrudes into white tooth, down move without exception; Subtraction then needs along the sliding borrow seam that ends borrow of circular arc.

Because the upper and lower end at digital bar is equipped with arrow, when producing mistake on traffic direction, this moment, pen just can not arrive at the end of dialling several mouthfuls, simultaneously, the arrow of correction traffic direction then occurred in display window, to correct the computing action, prevented mistake.

The utility model is simple in structure, and product can adopt injection mo(u)lding, not only can use in the storehouse handling of goods and materials, and its writing case with at present student's use can be united two into one, and makes the writing case with simple computation function.
