The specific embodiment

Below, based on accompanying drawing the embodiment that the present invention suits is described.In addition, embodiment is not limited to following mode, if can solve technical problem of the present invention, then can also implement other forms.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 are that the related index of expression embodiment of the present invention forms front view, side view, rearview, top view and the upward view with utensil 1.

This index forms with utensil 1 and is used for the books making index section 1 that the plurality of sheets of paper page or leaf is overlapped to form stacked or book shape such as folding at book, basis or file, as shown in Figure 6, by making cutting blades 3 at page 2, and make its leading section outstanding and form index laterally from the ora terminalis of page 2 its warpage.

As shown in Figure 7, this index forms with utensil 1 and consists of cutting knife 20 is installed in state receipts on the base station 10 and is loaded among housing 30a, the 30b.

Base station 10 is made of the metal-made parts, the central authorities when being arranged at overlooking of this base station 10 for the guideway 11 that inserts cutting knife 20.The internal diameter of guideway 11 is designed to the external diameter of cutting knife 20 basically identical, and cutting knife 20 is slided and moved up and down against guideway 11.

According to the sample attitude of guideway 11 quadratures therewith, the slit 12 that is provided for inserting page 2.It consists of like this: the intersect upper limb of formed base station of guideway 11 and slit 12 is the limit bladed, and by the interactive effect between this limit blade 13 and the cutting knife 20, the page in the inserted into gap 12 is cut.

Cutting knife 20 has flange part 21 in the top, inserts in the guideway 11 of base station 10 with the state of blade 22 towards the below that will be arranged at front end.

Between flange part 21 and base station 10, spring 40 is housed, all the time with cutting knife 20 to the base station 10 top application of forces.

Depress cutting knife 20 by overcoming this application of force, page 2 is cut off under the interactive effect between limit blade 13 and the cutting knife 20, depresses power by releasing, and cutting knife 20 turns back to initial position.

The blade 22 of this cutting knife 20 is this structure: as shown in Figure 8, by 12 the insertion section side down slop portion 23 downward-sloping towards both sides from the slit, cutting top 24 is arranged at the both sides of blade 22.

In addition, from the cutting top 24 that is arranged at both sides towards inner wall part 14 sides, form the acclivitous section 25 that is inclined upwardly.

By such formation, can be when depressing cutting knife 20, at first, by the cutting top 24 cutting pages 2 of both sides, then, by down slop portion 23 forms cutting blade 3 towards the zone of leading section 3a, cut the base portion that forms cutting blade 3 by the section of being inclined upwardly 25 simultaneously.

Namely, because the blade 22 of cutting knife 20 is from the insert port side of page 2 structure downward-sloping towards both sides, so, can after the both sides of cutting blade 3 are cut by the cutting top 24 of both sides (with reference to Fig. 9 (a)), gradually cut (with reference to Fig. 9 (b)) towards leading section 3a.

Therefore, the leading section 3a of cutting blade 3 can be by under the excessive pressure, so, can 12 when extracting page 2 out, prevent that cutting blade 3 cards are hung on the guideway 11 from the slit.

And, as shown in Figure 9, because arbitrary rake (23,24,25) all taked from cutting knife 20 both sides towards the structure of central portion side with respect to the blade bow, so, the leading section 3a of cutting blade 3 can be prevented by under the excessive pressure, thereby the card extension can be more effectively prevented.

In addition, because the blade 22 of cutting knife 20 consists of according to acclivitous sample attitude from both sides towards inner wall part 14 sides, so, can gradually cut by the non-cutting zone 4 towards page 2 from the both ends of blade 22, thereby can make the boundary line (that is, the base portion of cutting blade 3) between cutting blade 3 and the non-cutting zone 4 attractive in appearance.

Particularly shown in Fig. 9 (c), because when being designed to depress cutting knife 20, the upper end 25a of the section 25 that is inclined upwardly is higher than limit blade 13, so, can prevent that cutting blade 3 from being cut, thereby can form the non-cutting zone 4 that from page 2 ora terminalis, has specific length.

By this, can utilize the utensil of perforator structure, form tongue-shaped cutting blade 3.

Be loaded on housing 30 by this cutting knife 20 is received with the assembly of base station 10, the index that forms present embodiment forms with utensil 1.
