Figure 18 represents to support being formed as cylindric rotating cam 25 as rotating and the figure of the formation of the bolster 26 that can move in the axial direction, and the formation shown in its with the Fig. 6 described as the first embodiment is corresponding., an end in front becomes large-diameter portion 26a in the bolster 26 shown in this Figure 18 also, and the other end at rear becomes minor diameter part 26b, and the bolster 26 shown in its basic comprising with Fig. 6 is identical.
In addition, in the bolster 26 shown in Figure 18, the end difference 26c of the some different ring-types of external diameter is formed at the central portion of axis, as shown in Figure 15 (a), one end of cam force application spring 27 abuts with this end difference 26c, works in the mode pressed to the rear end side of axis by rotating cam 25.
Figure 19 and Figure 20 is the figure of the formation being represented the rotating cam 25 used in this second embodiment by front view and partial section, in addition, Figure 21 be to the rotating cam of Figure 19 25 from its on the right side of (the second cam part side) side view of state of observing.
In first cam part 31 of the rotating cam 25 used in this second embodiment, be as one man equally spaced formed with three island protuberance 31a in the circumferential with the quantity of the pen core be contained in beam barrel.
And, be configured in the present embodiment, the incline direction of the cam surface 31b that any one the island protuberance 31a in each island protuberance 31a is formed, become axial symmetry with the incline direction of the cam surface 31b formed on other island protuberances 31a.
Namely, representing as in fig. 22 three island protuberance 31a launched, the incline direction of the cam surface 31b that upper and lower island protuberance 31a is formed is configured to, relative to axially have regulation angle and respectively towards equidirectional, on the other hand, the incline direction of the cam surface 31b that the island protuberance 31a of central authorities is formed is configured to, and becomes axisymmetric incline direction relative to the incline direction of above-mentioned two cam surface 31b.
Namely, when the pressing bar 18 making to be positioned at upper and lower any one the island protuberance 31a shown in Figure 22 slides towards the front of beam barrel, work in the mode of giving turning effort to the first direction of rotation around axle to rotating cam 25, when sliding in the front making the pressing bar 18 of the island protuberance 31a being positioned at the central authorities shown in Figure 22 towards beam barrel, work in the mode of giving turning effort to the second direction of rotation relative to above-mentioned first direction of rotation reversion to above-mentioned rotating cam 25.
According to this formation, in the mode that whole pressing bar 18 can not be made to slide towards the front of beam barrel simultaneously, namely work in the mode that whole pen core can not be made to stretch out simultaneously.
In fig. 22 in order to illustrate that above-mentioned action represents the jut 21 being formed at two pressing bars 18.These two juts 21 are identical with the first embodiment to be operated by stretching out of pen core and is moved to arrow a direction, but abuts relative to axially becoming symmetrical each cam surface 31b with incline direction simultaneously, and therefore rotating cam 25 becomes and can not rotate.Thus, whole pressing bar 18 can not be made forwards to move simultaneously.
In addition, in this combined type writing implement, when multiple pressing bar 18 will be made forwards to move simultaneously, the front end writing portion of each pen core that these pressing bars link collides near the front port of beam barrel, and multiple pressing bar therefore can not be made in fact forwards to move simultaneously.
But, in the first embodiment, under the state having dismantled front axle 2 from rear axle 3, become and can carry out above-mentioned action, such as, when deliberately forwards pulling out such action when catching whole pen core, whole pen core (pressing bar) becomes the state of stretching out, and produces the situation that can not return to original state.
Thus, by adopting the formation of above-mentioned first cam part 31 of the rotating cam 25 of the second embodiment, above-mentioned technical task can be eliminated.
In addition, according to the formation of the rotating cam 25 of above-mentioned second embodiment, the cam surface 31b that the situation that the jut 21 of pressing bar abuts with the cam surface 31b that upper and lower any one the island protuberance 31a represented by schematic diagram is in fig. 22 formed and the jut 21 of pressing bar and the island protuberance 31a of central authorities are formed abuts, because the incline direction of cam surface 31b is different, so the direction of rotation of rotating cam 25 is different.
But rotating cam 25 is configured to, which direction to be given rotation to all rotates recovery to original direction.
That is, as shown in Figure 19 ~ Figure 21, the second cam part 32 formed in the rearward end side of the axis of rotating cam 25, the end face of the cylindrical shape of rotating cam 25 is formed the cam part of two chevrons based on pair of cams face 32c, 32d.That is, be configured to, the boundary portion of cam surface 32c and 32d becomes the summit of the cam part of chevron.
This second cam part 32 acts on as follows: by abutting with the stationary cam portion 12 in the rear axle 3 shown in Figure 16, no matter rotating cam 25 carries out spinning movement to which direction thus, all rotates recovery to original direction.Thus, be locked to the locking action this point of the action of the fastener 31c of rotating cam 25 and the jut 21 before being removed by the forward motion of different pressing bars 18 about the jut 21 of pressing bar 18, identical with above-mentioned first embodiment.
According to combined type writing implement described above, consist of and possess rotating cam, this rotating cam is driven in rotation along with the forward motion of any one pressing bar and has the fastener above-mentioned pressing bar being locked to forward travel state, therefore, it is possible to eliminate this problem of length that must shorten the such as refill for ball-point pen as script owing to using pressing bar disclosed in patent document 1 and patent document 2.
Further, according to above-mentioned combined type writing implement, the action effect described in effect portion stretching out the foregoing invention such as the bad generation waiting action bad of the script that can effectively prevent from causing owing to using pressing bar disclosed in patent document 3 can be obtained.
But, when utilize shown in Figure 19 ~ Figure 21 rotating cam 25, as being illustrated in the schematic diagram according to Figure 22, although whole pressing bar 18 can not be made forwards to move simultaneously, but when staggering the timing making its forwards movement for each pressing bar 18, the situation that can make the forwards movement of whole pressing bars 18 also can be produced.
In this case, as mentioned above, whole pen core (pressing bar) becomes the state of stretching out and it can not be made to return to original state.
Therefore, next shown Figure 23 and Figure 24 is the figure be described the mode of the rotating cam 25 can eliminating the problems referred to above further.Namely, Figure 23 and Figure 24 is the figure of the first variation represented based on the rotating cam shown in Figure 19, Figure 23 is the schematic diagram of the state of observing above-mentioned rotating cam 25 from the second cam part side, and Figure 24 is the schematic diagram the first cam part of above-mentioned rotating cam 25 being launched to represent.
In this first variation, for the mode increase shown in Figure 21 and Figure 22 addition of hachure part, namely with the stopper section 31e that hachure represents.
Rotating cam 25 is given above-mentioned first direction of rotation turning effort island protuberance (the island protuberance 31a of the upside shown in Figure 24) and to rotating cam 25 to relative to above-mentioned first direction of rotation reversion second direction of rotation give turning effort island protuberance (the island protuberance 31a of the central authorities shown in Figure 24) on, be formed with this stopper section 31e respectively.
And, each stopper section 31e is equipped with as represented by schematic diagram in fig. 24, respectively in the rear side relative with the side being formed with cam surface 31b of each island protuberance 31a.
According to this formation, as represented the jut of pressing bar in fig. 24 with symbol 21, when the front making any one pressing bar towards beam barrel is moved, the jut 21 being formed at another pressing bar abuts with any one stopper section 31e, stops the pressing bar possessing this jut 21 to slide towards the front of beam barrel.
Namely, as shown in figure 24, each jut 21 that two pressing bars 18 possess can slide towards the front of beam barrel as represented by arrow c, but the jut 21 that a remaining pressing bar 18 possesses abuts with stopper section 31e and is prevented from advancing as represented by arrow a.
Thus, as shown in Figure 23 and Figure 24, by being equipped with stopper section 31e to rotating cam 25, can effectively prevent whole pen core (pressing bar) from becoming the problem of the state of stretching out thus.
In addition, Figure 25 and Figure 26 is the figure representing its second variation based on the rotating cam shown in Figure 19, this Figure 25 and Figure 26 is observe the schematic diagram of the state of above-mentioned rotating cam 25 from the second cam part side and the first cam part launched the schematic diagram of expression.

The formation of the rotating cam 25 according to Figure 25 and Figure 26, the above-mentioned jut 21 being locked to the pressing bar 18 of the forward travel state of the fastener 31c that island protuberance 31a is formed is, in its locking by under the state removed, to slidingly contact with the raised 31f of buffering of the arc-shaped outstanding to the side of length direction of island protuberance 21a with the above-mentioned jut 21 being formed at pressing bar and the mode being turned back to going-back position by the applying power of above-mentioned back-moving spring 23 carries out action.
That is, owing to being formed with above-mentioned buffering projection 31f on island protuberance 31a, therefore the above-mentioned jut 21 of the pressing bar 18 of forward travel state carries out action in the mode turning back to going-back position after slidingly contacting with buffering projection 31f.
Accordingly, due to the existence of above-mentioned buffering projection 31f, and give braking to the return action of pressing bar 18, the impact produced when pressing bar 18 turns back to going-back position is relaxed.
Therefore, it is possible to reduce the impulsive sound produced in the return action of pressing bar 18, and can contribute to preventing from generating small bubble etc. in the ink owing to applying to impact to pressing bar 18 time normal in pen core.
In addition, Figure 25 and Figure 26 represents the example defining buffering projection 31f in the formation making the incline direction of the cam surface 31b being formed at island protuberance 31a mutually different (becoming axial symmetry), but this buffering projection 31f also can be applied to the same directional formation of incline direction as Fig. 7 ~ make as shown in Figure 10 cam surface 31b being formed at island protuberance 31a.
In this case, when the return action of pressing bar 18, on the path of above-mentioned jut 21 movement, namely, configure above-mentioned buffering projection 31f in a side of the length direction of each island protuberance 31a, identical action effect can be obtained thus.
Be configured in the embodiment described above, the barrel surface forming the cylinder-like part 25a of rotating cam 25 is axially formed as same diameter, and the jut 21 outstanding to axle center position being formed at pressing bar 18 slidingly contacts with the barrel surface of above-mentioned cylinder-like part 25a and move in the axial direction.Thus, the finger rest 20 along the pressing bar 18 of above-mentioned directional slit 11 movement moves with the state that the axle core with beam barrel is parallel.
Figure 27 represents the outside drawing to the 3rd embodiment that this situation represents, represents the part suitable with each portion described with identical symbol.In addition, any one finger rest 20 has been carried out the state of pressing operation towards the front of beam barrel by Figure 27 (a) expression.In addition, Figure 27 (b) represents that all fingers placement section 20 turns back to the state of the rearward end side of beam barrel.
Particularly as shown in Figure 27 (a), move in parallel relative to the axle core of beam barrel along the advance finger rest 20 of movement of directional slit 11, do not carry out the combined type writing implement as represented in the prior embodiment, finger rest 20 falls into action such in directional slit 11 along with forward motion.
