Description
Technical field
The present invention relates to Writing utensil equippedly, particularly relate to and have the Writing utensil equipped of a plurality of core components.
Background technology
It is in the prior art, Writing utensil equipped that to have a multi-core type that is equipped with a plurality of core components that contain refill (refill) in beam barrel inside Writing utensil equipped.In addition, also have the propelling pencil main body that comprises the core that to accommodate propelling pencil (propelling pencil) usefulness and replace refill Writing utensil equipped as core components.Usually, multi-core type is Writing utensil equipped to have mechanisms such as the slidingtype that can optionally use a plurality of core components, rotary, push button, has the front end (writing portion) that can make any core components by using this mechanism and is projected into outside structure from the peristome that is formed at the beam barrel front end.
But, being provided with in the tapering of preceding extreme direction undergauge at Writing utensil equipped beam barrel usually, the leading section in this tapering disposes peristome.In addition, even multi-core type is Writing utensil equipped, also Writing utensil equipped identical with single core pattern (core components is 1), peristome is one.Therefore, in single core pattern Writing utensil equipped, the stagger central shaft arrangement of peristome of arbitrary core components.
Promptly, the core components of selecting by said mechanism before writing portion arrives peristome process and under the outstanding state of peristome, shown in Figure 13 (a), core components 107 bears active force by the inclined plane that constitutes the tapering along center position and is forced to change direct of travel.In other words, outstanding for the front end that makes core components 107 from peristome 115, core components 107 is moved to the direction of intersecting with central shaft.At this moment, in beam barrel inside, as shown in figure 14, bearing active force and keep the core components of the state with angle and other core components with respect to central shaft along center position is contact condition or near state.
To be contained in beam barrel inside once more from the outstanding core components 107 of peristome 115 from this state, and make other core components 107 from this peristome 115 when outstanding, this core components 107 can not smooth and easyly move (smoothly) sometimes.Promptly, from the state shown in Figure 13 (a), the core components 107 that is contained in beam barrel inside once more is because of being released to the active force of center position effect by peristome 115 acies, so only become the active force in the direction of principal axis effect, moves on the track shown in Figure 13 (b).Thus, intersect with other core components 107 or contact (mainly being the tapering) midway of accommodating core components 107, so core components 107 is difficult to turn back to swimmingly beam barrel inside.
Particularly, make under other core components 107 situation outstanding, because the friction that produces between formerly outstanding core components 107 and this other core components 107 makes the time delay till outstanding earlier core components 107 is accommodated beam barrel inside from above-mentioned state.On the other hand, other core components 107 that moves towards peristome uses said mechanism to move to the preceding extreme direction of beam barrel artificially, therefore, does not exist core components 107 to arrive the influence of time delay till the peristome 115 etc. because of above-mentioned friction.That is because the moment that earlier outstanding core components 107 is housed in the beam barrel stagger, as shown in figure 15, before beam barrel is accommodated outstanding earlier core components 107, other core components 107 arrives near the peristome 115, and therefore, the core components 107 that produces both sides is stopped up and irremovable phenomenon by the tapering of beam barrel.Therefore, prior art Writing utensil equipped 101 in, during said mechanism, produce the chance that core components 107 interferes to each other in operation, therefore, return the core components 107 of beam barrel sometimes and deviate from the best time alternately from peristome 115 outstanding core components 107.
For addressing the above problem, in patent documentation 1, disclose a kind of the Writing utensil equipped of following structure that have, be provided with large-diameter portion, refill is dodged easily laterally with internal diameter bigger than the internal diameter of the base end side in tapering at private side with the tapering adjacency that is arranged at beam barrel.
Patent documentation 1:(Japan) spy opens the 2008-162246 communique
But, in record Writing utensil equipped, when the quantity that makes the core components that is disposed at beam barrel inside increases, be difficult to more carefully keep the shape of beam barrel in the patent documentation 1.Describe particularly, in patent documentation 1 Writing utensil equipped, widen the inner space, alleviate each refill contact and produce friction situation by the thickness of subduing beam barrel.In addition, in patent documentation 1 Writing utensil equipped,, also need subtract thin amount and subdue the thickness of beam barrel and guarantee the inner space with this even subtract thin beam barrel self, therefore, under the situation that increases core components, must the overstriking beam barrel.That is, in the invention of record, when increasing the quantity of core components, there is the problem that diminishes usability in the beam barrel chap in patent documentation 1.
Summary of the invention
Therefore, the present invention finishes in view of above-mentioned prior art problem, and it is a kind of Writing utensil equipped that its purpose is to provide, even increase the quantity of core components, does not also need the overstriking beam barrel, and core components can not contact each other and stop up inner generation of beam barrel.
For solving described problem, the invention provides a kind of Writing utensil equippedly, it comprises: front end has the beam barrel of peristome; Be disposed in the described beam barrel and front end has a plurality of core components of writing portion; Optionally make core components axially move the writing portion that makes this core components and be projected into outside operating unit from described peristome; Porose parts with the axial action of allowing core components, described porose parts have can make described a plurality of core components insert logical hole or groove respectively, in this hole or the groove interpolation be connected with each core components, this Writing utensil equipped being characterised in that: in the inside of described beam barrel, in that have than the more forward distolateral position configuration of described porose parts can be to the force application mechanism (first aspect) of each core components to the outside direction application of force.
