Below, with reference to accompanying drawing an embodiment of the invention are described.
This adhesive tape cutter be installed a spool 2 with small diameter adhesive tape installation portion 21 and major diameter adhesive tape installation portion 22 in the mode that can center on axle center m rotation as shown in Figure 1 on the spool filling department 11 of cutter main body 1.
For the cutter main body 1 of taking in spool 2, pass through ester moulding, between pair of sidewalls 1a, 1a, be provided with upward and adhesive tape is pulled out the cavity S of side opening, in this cavity S, constitute spool filling department 11, and be provided with the cutting edge 12 that is used to cut off adhesive tape pulling out away from this adhesive tape between locational pair of straight wall 1b, the 1b of side, wherein, between sidewall 1a and upstanding wall 1b, formed big recess 1c.Spool filling department 11, be provided with on the inside face of sidewall 1a the axial region 2a that is used to make spool 2 described later from above fall into and fall into the position and pull out the groove 11a that side moves a little to adhesive tape from this, and forbid pulling away upward in this mobile terminal and can be supported spool 2 rotatably.
On the other hand, spool 2 is shown in Fig. 2～4 grades, extend 3 tabular arms 20 from the axle center m of axial region 2a to the radiation direction star-shapedly, on the leading section of this arm 20, form major diameter adhesive tape installation portion 22, and the center O of small diameter adhesive tape installation portion 21 is set between specific arm 20 and arm 20 from the axle center m of spool 2 as shown in Figure 3, with departing from predetermined distance d.Thereby major diameter adhesive tape installation portion 22 is parts of giving prominence to the partial circle arcuation in the interior week that closely is entrenched in major diameter adhesive tape X (with reference to Fig. 7) with axle center m abreast from the leading section of arm 20, on the other hand, small diameter adhesive tape installation portion 21 is the barrel-contoured parts that extend abreast with axle center m on the position of the axle center m that leaves spool 2, and has the size relationship in the interior week that can insert small diameter adhesive tape Y (with reference to Fig. 6) loosely.
The concrete structure of spool 2, constitute by as Fig. 2 to Fig. 4, double-type spool tectosome 102 being docked each other, on spool tectosome 102, on position, form protrusion 121,122 respectively as small diameter adhesive tape installation portion 21 and major diameter adhesive tape installation portion 22.So, constitute: thus when a spool tectosome 102 is docked with another spool tectosome 102 around line of centers P upset, corresponding protrusion 121,121 each other, 122,122 all become chimerism each other.The line of centers P of this moment is the straight line that links the center O of the axle center m of spool 2 and small diameter adhesive tape installation portion 21.Promptly, constitute: becoming on the barrel-contoured protrusion 121 of small diameter adhesive tape installation portion 21, be provided with the scraping out thin-wall outside fitting portion 121a interior week and make the outstanding inboard fitting portion 121b that forms of thin plate sheet that digs up the corresponding partial circle arcuation of part with this from remaining semi-circular portions of semi-circular portions, separately outside fitting portion 121a is entrenched in the outside of the other side's inboard fitting portion 121b when the upset butt joint.In addition, constitute: on the protrusion 122 of the partial circle arcuation that becomes major diameter adhesive tape installation portion 22, be set side by side with the inboard fitting portion 122b of poroid outside fitting portion 122a of pin and pin shape on end face, outside fitting portion 122a separately is entrenched in the outside of the other side's inboard fitting portion 122b in when butt joint upset.That is, the spool 2 of present embodiment is that 102 upsets of spool tectosome and the butt joint of same configuration are formed.
In such structure, two spool tectosomes 102,102 are docked in the mode of small diameter adhesive tape Y being closed between each other, thus the hole of small diameter adhesive tape Y is inserted and lead on small diameter adhesive tape installation portion 21, be positioned at the axis direction both sides of small diameter adhesive tape Y as (with reference to the shadow part 20p among Fig. 4) near the base end part of the arm 20 of the part of spool tectosome 102 this moment, becomes the state of the dislocation that has limited its Width.Small diameter adhesive tape installation portion 21 can be slidably supported the central part of small diameter adhesive tape Y, and is relative therewith, and major diameter adhesive tape installation portion 22 is after docking spool tectosome 102,102 each other, with closely chimeric its outside that is installed in, the hole of major diameter adhesive tape X.In the present embodiment, shown in Fig. 1, Fig. 5 etc., the axle center m of spool 2 is set near the upper end of sidewall 1a of cutter main body 1 and on the position near recess 1c, under the state that spool 2 is installed on the spool filling department 11 at least at a certain position of rotation, as shown in Figure 8, the leading section part of 2 arms 20 is projected into the superjacent air space of cutter main body 1 and pulls out the space of the recess 1c of side to being positioned at adhesive tape, thereby presents form and the diverse brand new outward appearance of cutter in the past.
In addition, on the outside face of spool 2, be provided with triangular marker T with the state that can discern as shown in Figure 2 as the identification part of expressing eccentric direction.This mark T plays the effect of expressing 1 the regional F that to be suitable for to draw small diameter adhesive tape Y from be formed between 3 arms 20 3 regional F, F ' towards the outside of small diameter adhesive tape installation portion 21, F '.In addition, on each arm 20, be provided with upwardly extending otch 20a, the distolateral part that always arrives the protrusion 122 that constitutes major diameter adhesive tape installation portion 22 continuously of this otch 20a in radiation side at its Width central portion.
The adhesive tape cutter of the present embodiment of Gou Chenging like this, as shown in Figure 6 the central part of small diameter adhesive tape Y can be slidably supported on small diameter adhesive tape installation portion 21, and with the extraction unit y1 of this small diameter adhesive tape Y when major diameter adhesive tape installation portion 22 is pulled out laterally, because the center O of small diameter adhesive tape installation portion 21 is with respect to the axle center m off-centre of spool 2, so being positioned at respect to the axle center m of spool 2 up to the center O of small diameter adhesive tape installation portion 21, spool 2 rotation pulls out side, roughly be stabilized in this position then, because the relation of the binding force of adhesive tape, small diameter adhesive tape Y is not to tangential direction from outer peripheral face but is drawn out of to eccentric direction roughly (by the axle center and towards the direction of center O).At this moment, even sliding resistance by small diameter adhesive tape installation portion 21, act on the spool 2 as rotational force, also can only be to repeat following action, promptly, spool 2 rotates a little, and small diameter adhesive tape installation portion 21 just is pulled, and this moment, the such action in original position was returned in spool 2 contrarotations.The rotatable phase position of spool 2 does not have than cataclysm like this, between the extraction unit y1 of small diameter adhesive tape Y and major diameter adhesive tape installation portion 22, kept roughly certain position relation, major diameter adhesive tape installation portion 22 can not be positioned at it and extract direction out, so the extraction unit y1 of small diameter adhesive tape Y can be avoided major diameter adhesive tape installation portion 22, suitably pull out laterally.
Therefore, thus can effectively avoid the extraction unit y1 of the small diameter adhesive tape Y that the excessive rotation by spool 2 causes and the interference between the major diameter adhesive tape installation portion 22 to obtain suitable running condition.In addition, because small diameter adhesive tape installation portion 21 does not separate, so do not need to carry out component management, and then not only can replace small diameter adhesive tape Y that major diameter adhesive tape X is installed as shown in Figure 7, and can under the state that small diameter adhesive tape Y has been installed, install and use major diameter adhesive tape X, do not unload lower member ground so can try one's best and use small diameter adhesive tape Y and major diameter adhesive tape X, such ease of use excellence respectively.
At this moment, spool 2 is to radiating the parts that direction is extended many arms 20 and formed major diameter adhesive tape installation portion 22 at the leading section of this arm 20 from axle center m, at least can pull out small diameter adhesive tape Y from the regional F between adjacent arm 20 and the arm 20, so the outward appearance novelty also presents functional attractive in appearance, and can be in the situation of installing condition and the surplus of small diameter adhesive tape Y etc. from regional F, F ' between all arms 20 and the arm 20, F ' identification small diameter adhesive tape Y, though be unexistent in the past form, also can know and how to use.
Particularly, spool 2 is to radiating the parts that direction is extended 3 arms 20 and formed major diameter adhesive tape installation portion 22 at the leading section of this arm 20 from axle center m, and can make small diameter adhesive tape installation portion 21 eccentric between arm 20 and the arm 20 to arbitrarily from axle center m, so small diameter adhesive tape Y just in time is drawn out by the space between adjacent arm 20 and the arm 20 as shown in Figure 6.Therefore, prevented interference with the major diameter adhesive tape installation portion 22 of the front end that is positioned at arm 20 effectively.And, because the space between arm 20 and the arm 20 is open obliquely upward, so can access from the such state of existence of the easier identification small diameter adhesive tape Y such as direction of for example Fig. 1.As long as arm 20 is the odd number root, just equally effectively play such effect, if but the number of arm 20 is more, then just narrows down between arm 20 and the arm 20, so arm 20 still is preferably about 3.
And, when being installed in spool 2 on the spool filling department 11, at least at a certain position of rotation, as shown in Figure 8, the leading section that becomes 2 arms 20,20 is projected into superjacent air space to the adhesive tape of cutter main body 1 partly and pulls out state such in the space of side, so the extraction position suitable of adhesive tape not only, its hold mode are also stable, and have constituted functional outward appearance of unexistent brand new adhesive tape cutter in the past.
In addition, for this spool 2, because relation with the eccentric direction of small diameter adhesive tape installation portion 21, the extraction position of small diameter adhesive tape Y is limited, but because can be provided with mark T from the state that the outside face of spool 2 is discerned as the identification part of expressing eccentric direction, so only GPRS should be pulled out small diameter adhesive tape Y from the direction of mark T, can be that clue easily is configured on the cutter main body 1 just with mark T.
As concrete structure, spool 2, by being docked each other, double-type spool tectosome 102 constitutes, when this makes it to dock, state with the offset of the axis direction that limits this small diameter adhesive tape Y by base end part as the arm 20 of the part of spool tectosome 102, small diameter adhesive tape Y is enclosed in the small diameter adhesive tape installation portion 21, so can carry out the loading and unloading of small diameter adhesive tape Y under with spool tectosome 102 state in two simply, even with the loosening of appropriateness that can slide small diameter adhesive tape Y is installed on the small diameter adhesive tape installation portion 21, also can accesses the stable of small diameter adhesive tape Y, the failure-free hold mode.
Like this, small diameter adhesive tape installation portion 21 can be slidably supported the axial region 2a at the center that is positioned at small diameter adhesive tape Y, with respect to this, major diameter adhesive tape installation portion 22 can closely be entrenched in the inboard of major diameter adhesive tape X its outside under the state that spool tectosome 102,102 is docked each other, be accompanied by and pull out major diameter adhesive tape X, spool 2 integral body are keeping continuing to a direction rotation with the state ground of major diameter adhesive tape X tight joint.Y is different with small diameter adhesive tape, under the situation of major diameter adhesive tape X, can not produce the problem with interferences such as each adhesive tape installation portions 21,22 especially.And, at least when the loading and unloading of major diameter adhesive tape X, do not need the assembling/decomposition of spool tectosome 102, thus the each such inconvenience of hold mode that all must remove small diameter adhesive tape Y when also having eliminated on small diameter adhesive tape Y being remained on inboard small diameter adhesive tape installation portion 21.
And then, owing to constitute: a pair of spool tectosome 102 as the position of small diameter adhesive tape installation portion 21 and major diameter adhesive tape installation portion 22 on form the protrusion 121,122 of same structure, when docking with another spool tectosome 102 making a spool tectosome 102 counter-rotating, protrusion 121,121 each other, 122,122 become chimerism each other, so the key element that is used to constitute installation portion can be directly used in embedded structure, but the shaping of the protrusion 121 that docks mutually of green phase isostructure in addition, thereby also help being shaped.
Specifically, form outside fitting portion 121a and inboard fitting portion 121b on each protrusion 121 that constitutes small diameter adhesive tape installation portion 21, when counter-rotating made it to dock, each inboard fitting portion 121b was entrenched in the inboard of the other side's outside fitting portion 121a; And, on each protrusion 122 that constitutes major diameter adhesive tape installation portion 22, form outside fitting portion 122a and inboard fitting portion 122b, when counter-rotating made it to dock, each inboard fitting portion 122b was entrenched in the inboard of the other side's outside fitting portion 122a.So, can adopt identical 2 the spool tectosomes 102 of unitary construction, so can realize the reduction of part count effectively.
And then, as mentioned above, can be provided with mark T from the state that the outside face of spool 2 is discerned as the identification part of expressing eccentric direction, even so in each spool tectosome 102 as protrusion 121 off-centre of small diameter adhesive tape installation portion 21, eccentric direction also comes into plain view, can carry out chimericly with suitable phase relation, easily constitute spool 2.
In addition, the concrete structure of each several part is not limited to above-mentioned embodiment.
For example, constitute the embedded structure of the protrusion of major diameter adhesive tape installation portion, can embed pin then therein, realize the relation of pin and pin hole by making 2 pin holes.In addition, be not limited to the mode of such pin and pin hole, can certainly on major diameter adhesive tape installation portion, adopt the identical structure of embedded structure ( fitting portion 121a, 121b) with the diagram protrusion 121 that constitutes small diameter adhesive tape installation portion 21.
In addition,, replace axial region can be supported on the spool in the past that uses on the recess as the spool filling department of cutter main body rotatably if use above-mentioned spool 2, then can be only exchange by spool 2 constitute cutter of the present invention simply.
And then above-mentioned eccentric structure is also effective in the purposes beyond the cutter.For example, in print field, field of textiles etc., sometimes sheet material, the coil of wire to be pulled out on cylinder, during at needs and with minor diameter cylinder and major diameter cylinder, as shown in Figure 9, can a spool 2h being installed on the spool filling department, on this spool 2h, thereby minor diameter cylinder installation portion 21h and major diameter cylinder installation portion 22h formation roller holding mechanism are set around the mode of axle center m rotation.This spool 2h, at least on minor diameter cylinder installation portion 21h, can be slidably supported the central part of minor diameter cylinder r, the center O of minor diameter cylinder installation portion 21h is positioned on the m accentric position, axle center with respect to described spool 2, will pulls out laterally from the extraction unit r1 of this minor diameter cylinder r thereby avoid major diameter cylinder installation portion 22h.At this moment, even the sliding resistance when pulling out minor diameter cylinder r is by minor diameter cylinder installation portion 21h, act on the spool 2h as rotational force, also can utilize minor diameter cylinder installation portion 21h to trend towards being positioned at the character that cylinder is pulled out side, do not make spool 2h rotation and make it stable, thereby prevent the change of the position relation of minor diameter cylinder r and major diameter cylinder installation portion 22h.
So also can prevent the driven rotation of spool 2h with above-mentioned embodiment identically, can effectively eliminate from the extraction unit r1 of minor diameter cylinder r and the problem of major diameter cylinder installation portion 22h interference.
Certainly, if spool is constituted, possess the minor diameter cylinder installation portion 21h of the central part that can be slidably supported minor diameter cylinder r and will be arranged on the major diameter cylinder installation portion 22h of the outer circumferential side of this minor diameter cylinder installation portion 21h from the state that the extraction unit of this minor diameter cylinder r is pulled out laterally can not hinder, and the center O of minor diameter cylinder installation portion 21h is positioned on the axial region m accentric position with respect to spool 2h, then can be only, its spool with in the past roller holding mechanism constitutes roller holding mechanism of the present invention simply by being intersected to bring.
Other formation can be carried out various distortion too in the scope that does not break away from purport of the present invention.
