Abstract
The utility model relates to a pencil lead for depiction machine read cards, which is used for checking examination paper by a computer for standardized examinations and is composed of two flat cuboids of a wide and a narrow cuboids. The end parts of the wide and the narrow cuboids are provided with slopes. The widths of flat surfaces are respectively 1.7 mm and 1.5 mm. The slopes are made into angles with 45 DEG. The utility model has the advantages of simple structure, convenient operation and portability, difficult fracture, one-time accomplishment of depiction, time saving, labour saving, high speed and high quality and is convenient for satisfying to accurately check the examination paper by the computer for two kinds of standardized examinations of nationals, provinces and cities. The popularization and the application of the pencil lead for depiction machine read cards can make an active contribution for modern standardized examinations.
Description
The utility model relates to a kind ofly be used for standardization examination and carry out computer and declare volume and the time describe the machine-read card pencil-lead.
Describe HB or 2B pen core that pen core that machine-read card uses mostly is the garden type at present, filling out when painting machine-read card, need to come and go just can fill out to paint for several times and finish, time-consuming first, second because pen core is a garden shape, stress surface is little, very easily fracture, and after coming and going for several times, calcellation phenomenons such as easily offscale or discontented lattice give that accurately declaring winding comes trouble, even cause the error of declaring volume, though a kind of flat pencil-lead is arranged, can only be used for a kind of machine-read card, can not satisfy the needs of country and province's liang kind machine-read card.
The purpose of this utility model just provide a kind of novel be exclusively used in country and economize the standardization examination of liang kind describe the machine-read card pencil-lead.
The purpose of this utility model is achieved like this, and pen core adopts bipartite flat shape, and there is an inclined-plane at its both ends, and it is best to be generally miter angle, and wide of pen core is 1.7mm, and leptoprosopy is 1.5mm, and is just in time consistent with the square frame width of machine-read card.
The utility model is simple in structure, portably uses conveniently, and frangibility is not described once to finish, and is time saving and energy saving, can satisfy country easily simultaneously and economizes liang kind standardization examination computer and accurately declare volume.
Below in conjunction with accompanying drawing structure of the present utility model is done to say in detail.(accompanying drawing all is enlarged diagrams).
Fig. 1 is a structure front view of the present utility model.
Fig. 2 is the vertical view of the utility model structure.
Fig. 3 is the utility model structure left side view.
By shown in Figure 2, its structure of the utility model is to be made of wide long flat-square shaped 1 and long narrow flat-square shaped 2, there is inclined-plane 3 end of wide long flat-square shaped 1, there is inclined-plane 4 end of long narrow flat-square shaped 2, two wide square frame width with country and provinces and cities machine-read cards are consistent, inclined- plane 3,4 all is miter angle, and the flat face width of general wide long flat-square shaped 1 is 1.7mm, and the flat face width of long narrow flat-square shaped 2 is 1.5mm.
From the above, the utility model, need not come and go for several times so can once describe because the square frame width of its flat face width and machine-read card is identical, because the pen core end is the inclined-plane, save time when describing, laborsaving, and avoid scratching paper, and because of lifting surface area big, pen core is frangibility not, do not have offscale yet or, improved speed, guaranteed to describe the quality of machine-read card less than calcellation phenomenons such as lattice.
When using the utility model, because of national general examination for students from various schools is few, provinces and cities' examination is many, so width two flat cuboids can be made different length, long narrow flat-square shaped is used for national general examination for students from various schools, and wide long flat-square shaped is used for provinces and cities' examination, pen core is contained in the rod, its pen core material is cut from the inclined-plane on top with the stationery cutter with existing pen core, rejects peripheral wooden, expose the inclined-plane pen core, when cutting, and do not damage the width on inclined-plane, otherwise the speed and the quality of the continuous card of machine are described in serious overslaugh, after cutting, the right hand is write, and the inclined-plane is downward, allows the pen core alignment machine talk the limit of card, by a right lateral, till the square frame right side bearing, like this, just can instantaneously fast describe a machine-read card square frame.Of the present utility model applying must be declared volume for computer and bring great convenience, for the standardization examination in modern times is made contributions.
Claims (3)
1, a kind ofly describes the machine-read card pencil-lead by what long flat-square shaped constituted, it is characterized in that long flat-square shaped is to be made of wide long flat-square shaped (1) and long narrow flat-square shaped (2), there is inclined-plane (3) end of wide long flat-square shaped (1), there is inclined-plane (4) end of long narrow flat-square shaped (2), two wide square frame width unanimities with machine-read card.
2, the machine-read card pencil-lead of describing according to claim 1 is characterized in that said inclined-plane (3), inclined-plane (4) all are 45 jiaos.
3, the machine-read card pencil-lead of describing according to claim 1, the flat face width that it is characterized in that said wide long flat-square shaped (1) is 1.7mm, the flat face width of long narrow flat-square shaped (2) is 1.5mm.
