The specific embodiment

Narrate with regard to one embodiment of the invention below.

According to ruler R vertical view of the present invention as shown in fig. 1, a-a cutaway view among Fig. 1 as shown in Figure 2, possess the main body 1 that constitutes by transparent plastic elongated plate and the anti-slip component 21 that is made of soft material embedded and be located at anti-skidding the patchhole 1h that connects along thickness direction on the main body 1 and anti-skidding 2 of forming.

More particularly, on long limit 1x, the 1y of the both sides of main body 1 outer rim, have scale 1x1,1y1 respectively.And subsidiary is a side scale 1x1, and its center is consistent with the longitudinally center of main body, and the opposing party's scale 1y1 is a datum mark with main body one side's minor face 1z.

So, be provided with along the longitudinally extension, along the narrow slit 12 of wall thickness direction perforation in the short side direction substantial middle portion of main body 1.The width dimensions of this narrow slit 12 is set the size of can the tighter blade that thickly inserts cutting knife etc. cutting off tool C for.And have narrow slit scale 12x along this narrow slit 12.This narrow slit scale 12x, corresponding long limit between the scale 12x1-12x1 at two ends as the known size of the size of photo, corresponding the length of 10cm between its inboard scale 12x2-12x2, two end lines of corresponding the minor face as the known size of the size of photo are provided with center line 12x4 in central authorities between the scale 12x3-12x3 of inside.Moreover, in the present embodiment, be provided with recess 12a at these narrow slit 12 peripheries.This recess 12a is the shape person who expands slit width upward.

On the other hand, though aforementioned anti-skidding 2 anti-slip component 21 that is handle is made of soft material as previously mentioned embeds along anti-skidding patchhole 1h of wall thickness direction perforation and forms, but be to become the Long Circle person when overlooking, be disposed at a plurality of positions along the longitudinally compartment of terrain.More particularly, the wall thickness direction substantial middle portion at aforementioned anti-skidding patchhole 1h is provided with the raised line 1h1 that extends along the peripheral direction of this anti-skidding patchhole 1h.On the other hand, be provided with in the wall thickness direction substantial middle portion of aforementioned anti-slip component 21 and constitute the groove 21a that cooperates with aforementioned raised line 1h1, make this groove 21a and aforementioned raised line 1h1 insert aforementioned anti-skidding patchhole 1h to aforementioned anti-slip component 21 ordinatedly.And, for example, as shown in Figure 2, its surperficial 2a is retreated a little from the lower surface 1a of main body 1, not from above apply and do not contact paper etc. under the state of external force and cut off object, do not bring into play antiskid function.

Cutting the paper of use of printing photo such as the printer used by means of personal computer or card etc., or other page classes etc. cut off when the object P, aforementioned narrow slit 12 is caused in cutting profile partly.Then, pin ruler R from the top.Then, cut-out tool C such as the blade of cutting knife are inserted narrow slit 12, aforementioned cut-out tool C is moved along narrow slit 12.

So,, become straight line more reliably so joint-cutting is compared with the occasion of using ruler always because the narrow slit 12 that the moving direction of cut-out tool C is subjected to extend point-blank limits.

At this moment,, pin anti-skidding 2 of ruler R from the top, then bring into play its function,, can cut off the position of wanting more reliably so ruler R is not easy to slide owing to anti-slip component 21 is pressed against aforementioned cut-out object P with finger F if as shown in Figure 3.

On the other hand, if do not pin ruler R, then,, aforementioned narrow slit 12 is caused in cutting profile partly so ruler R is similarly slided with always ruler on cut-outs objects such as paper owing to do not bring into play function for anti-skidding 2 from the top.

And, if cutting part is rectangle as the known size of the size of photo, then between the scale 12x1-12x1 in the outside by long limit being set in narrow slit scale 12x, minor face is set between the scale 12x3-12x3 of inboard of narrow slit scale 12x, can only be taken as necessary length to joint-cutting.And, can only get joint-cutting in the part of necessity, can not stay unnecessary joint-cutting on the remaining part cutting.

In addition, owing to be provided with recess 12a, insert this narrow slit 12 cutting off tool C easily at narrow slit 12 peripheries.

Moreover, the invention is not restricted to above-described this embodiment.

For example, the shape of anti-skidding portion, also can be to extend to the roughly whole length person of ruler R along the longitudinally of ruler R as shown in Figure 4, also can be to become orbicular anti-skidding 2 group further compartment of terrain configuration of arranging along longitudinally a plurality of (being 3) as shown in Figure 5 when overlooking here.

In addition, narrow slit can be the whole length person who roughly extends to ruler R along the longitudinally of ruler R as shown in Fig. 6 and Fig. 7 also, also can be provided with along both sides except the hypotenuse of set square R2 as shown in Figure 8.In the latter's formation, can joint-cutting be met at right angles.And then, as shown in Fig. 9 and Figure 10, can not that straight line but swash shape or zigzag ground extends, also can set other arbitrary shapes for.

And then, also can at random set except person described in the above-mentioned embodiment along the scale that narrow slit portion is provided with, also can omit.

And, replace recess being set at the narrow slit periphery, also can be taken as herringbone etc. to the section configuration of narrow slit, make to insert easily by additive method and cut off tool.

In addition, anti-skidding portion brings into play its merit able one all the time, otherwise also can omit anti-skidding portion.In addition, shown in cutaway view among Figure 11, also can inject the recess 11 that is located on the main body 1 lower surface 1a to soft material and form anti-skidding 2.In this occasion, if press...with one's finger anti-skidding 2 periphery, then main body 1 distortion and anti-skidding 2 are pushed out, and are pressed against to cut off object and bring into play its function.

In addition, the interval of scale etc. also can change at random in the scope that does not undermine spirit of the present invention.

The present invention is as above detailed description, owing in becoming tabular ruler, connect the wall thickness direction, is provided with the narrow slit that guiding cutting knife etc. cuts off the moving direction of tool, so compare the joint-cutting that can obtain the shape wanted reliably with ruler always.
