Abstract

The utility model relates to a multifunctional automatic writing pen for standard test paper. The utility model has the technical proposal that a pair of sleeve pipe type elastic pen core driving mechanisms is arranged in a pen holder of a writing pen with an ordinary structure. When the utility model is used, a mouth of a pen core on the lower end of the pen holder is jointed on the message frame of a read card of an examination machine (examination paper). The pen core driving mechanisms are thumbed by fingers. Under the action of the mechanical elastic force of the mechanisms, a head of the pen core can make standard coating actions on the examination paper to blacken the message frame of the examination paper. Because the strength of writing of the utility model is controlled by the action of the mechanical elastic force, an examinee are easy to control the strength of coating and writing. Thereby, the action of question answer can be standardized, and the speed of the question answer is raised for being favorbal to the exertion with normal level of the examinee.

Description

Multifunction automatic writing pen for standard test paper

The utility model relates to a kind of pen, and particularly a kind of being used in scribbled the multi-functional correction pen that message box or others are write on the standardization examination machine-read card.

Standardization examination is a kind of form that extensively adopts in all kinds of in recent years examinations, generally requires the examinee directly to be coated with message box---circular frame or rectangle frame on the black machine reading examination paper with 2B type pencil in this type of examination.Because each examinee's concrete condition difference, the weight of blacking and qualification have different, so be difficult to try to achieve the standardization that paper is scribbled, so just can cause the erroneous judgement of automatic marking machine sometimes and cause the examinee to lose points, even directly have influence on examinee's future.In Chinese patent CN91301991.7 file, once disclosed a kind of bushing formula answer normalizer, it is by a kind of mode of opening a plurality of and information circle footpath small opening of the same size on transparent block, make every effort to make examinee's test paper to scribble standardization, but because this mode of passing through the small opening blacking still is a manual method, still be difficult to grasp weight, increased on the contrary the examinee march into the arena with the quantity of stationery, added new inconvenience to the examinee.

The purpose of this utility model is to overcome the defective of prior art, and a kind of simple in structure, easy to use, automatic correction pen of the normalized multi-functional standardization examination of blacking is provided.

The technical solution that realizes the foregoing invention purpose is that a secondary bushing type elasticity pen core driving mechanism is set in the penholder of plain edition structure lettering pen.During use with the lower end pen core mouth of penholder on the message box that is combined in device for examining Card Reader (paper), and with pointing pressing pen core driving mechanism, under the mechanical elasticity power effect of this mechanism, pen core head can be made the coating action of standard on the volume face, with the message box blacking of device for examining Card Reader.In the utility model and since the correction pen dynamics of starting to write be by mechanical elasticity power be used for control, make its answer standardization thereby so just make the examinee be easy to grasp the weight of scribbling, the while has also been saved the time for the examinee.As if other pen core is fixed or changed to the pen core of this pen and being fixed, then this correction pen also can be write as conventional pen.

Specific embodiment of the utility model by literary composition after shown in the accompanying drawing.

Accompanying drawing 1 is the structural representation that is used for the correction pen of blacking circular information frame.

Accompanying drawing 2 is the structural representation that is used for the correction pen of blacking rectangle message box.

With reference to accompanying drawing, the automatic correction pen of multi-functional standardization examination described in the utility model by the cap for brush 1, with the penholder 2 of the cap for brush 1 coaxial fit and bar in pen core tube 3 etc. form, bushing type elasticity pen core driving mechanism is located in the penholder.In view of the message box of being painted on the standardization examination machine-read card generally all is circular or rectangle, the utility model also can be designed two kinds of structures in view of the above, below is narrated respectively.

The correction pen structure that is exclusively used in blacking circular information frame as shown in Figure 1.In this structure, bushing type elasticity pen core driving mechanism has a rotating casing 4 that is set between penholder 2 and the pen core tube 3, is respectively equipped with the multi-thread negative and positive screw thread that cooperates each other on the internal face of the outside wall surface of rotating casing 4 and penholder 2.What the inwall bottom of rotating casing 4 had also that but a circle Kato lives pen core tube 1 tail end expands step 41, is provided with a secondary pen core holddown spring 5 in sleeve pipe, and this spring 5 is pressed on sleeve pipe and expands between step 41 and the cap for brush 1 roof.The pen core mouth 21 of penholder 2 is a bit larger tham the frame footpath of device for examining Card Reader circular information frame in this kind structure, and lead for retractable pencil 7 folded in the pen core tube 3 equates substantially with the frame footpath of message box.During use, at first 21 pairs in pen core mouth is combined on the paper message box, the upper end of pinning pen with forefinger presses down, and then rotating casing 4 around the downward precession of multi start thread, drives pen core tube 3 rotations with respect to penholder 2 bodies of rod, thereby has stayed the circular information point of standard on paper.

Provided the structure of the correction pen that is exclusively used in blacking rectangle message box in the accompanying drawing 2, in this structure, bushing type elasticity pen core driving mechanism comprises that one is set in sleeve pipe that sleeve pipe 4 between penholder 2 and the pen core tube 3, end be located at penholder 2 inwall bottoms and drives shell fragment 6 and a pair and be located at pen core holddown spring 5 between sleeve pipe 4 and the pen core tube 3.Be provided with a circle in sleeve pipe 4 upper inside wall and expand step 42, also be provided with a circle in the outer wall bottom of pen core tube 3 and expand step 31, pen core holddown spring 5 is placed between this two step 42,31.In addition, the opposite side that drives shell fragment 6 with respect to sleeve pipe on penholder 2 bar walls has a finger pressure through hole 22, can make the horizontal application of force to pen core tube 3 after finger is pressed this through hole 22.The pen core mouth 21 of penholder 2 also should be a bit larger tham the frame footpath of rectangle message box on the device for examining Card Reader in this structure, and the cross section of lead for retractable pencil 7 can be flat.During use,

depress penholder

2,21 pairs in pen core mouth is combined on the paper message box, pass through finger pressure through hole 22 pressing pen core tubes 3 with finger, make under its effect that drives shell fragment 6 at sleeve pipe and do level, drive lead for retractable pencil 7 coating back and forth on paper, thereby standard ground is with the message box blacking to moving back and forth.

Compared with prior art, adopt correction pen described in the utility model have the standard of scribbling, answer rapidly, avoid the advantage such as apparatus for marking examinating paper erroneous judgement, can greatly eliminate the nervous psychology that the examinee causes because scribbling answer, be conducive to examinee's level of bringing into normal play. Its product can be widely used in national common college entrance examination, adult's examination and the multiple examinations such as TOEFL, GRE.
