Row indicate the 2nd distance D2.1st distance D1 is the thickness (0.06mm) that the shortest distance is set as to paper portions P, then from
0.1mm starts gradually to increase 0.1mm.2nd distance D2 is that the shortest distance is set as 0mm, gradually increases 1.0mm since 0mm.
In each form, so that the paper portions P extracted out from roll paper R is transported with relaxed state, torn using (not shown)
Disconnected bar, the paper portions P that will be discharged from paper outlet 1a (with reference to Fig. 3) is in such a way that the length of conveyance direction becomes 150mm
Cut-out, the correction degree of trace is wound according to following criterion evaluation, and its result is summarized into table 1.
Fig. 6 is the figure of the method for the correction degree of the winding trace for illustrating to assess paper portions.
Paper portions P after cut-out is placed in outer surface Po on horizontal face S upward, determines placed paper
P distances in part are considered as maximum height h for the height of the face S of its mounting.In the judgement of the correction of winding trace, to most
Big height h be 48mm or less situation draw zero (winding trace correction from practicability for fully), be more than to maximum height h
The case where the case where 48mm or the paper portions P as shown in the right side of Fig. 6 are crimped draw × and (correction of winding trace is from reality
With insufficient in property).
[table 1]
As shown in table 1, in the case where the 2nd distance D2 is set as 0.0mm, until the 1st distance D1 is as 0.5mm
Only, it is the loose preceding part P2 of correction to occur to contact with floating preventing portion 51, and prevent the conveyance direction for being wrapping with part P1
Upstream end P11 deviate from original upstream end contact position 31a, as a result, paper portions P is imparted for from practicability
Sufficient corrective force.As long as in addition, the 1st distance D1 be 0.5mm hereinafter, so until the 2nd distance D2 as 2.0mm until,
Equally it can assign sufficient corrective force for from practicability to paper portions P.
In the case where the 1st distance D1 is set as 0.06mm identical with the thickness of paper portions P, until the 2nd away from
Until becoming 5.0mm from D2, sufficient corrective force for from practicability is assigned to paper portions P.It is set by the 1st distance D1
In the case of for 0.1mm, until the 2nd distance D2 becomes 4.0mm, in addition, in the feelings that the 2nd distance D2 is set as to 3.0mm
Under condition, until the 1st distance D1 becomes 0.4mm, paper portions P can be assigned for from practicability and adequately be rectified
Positive force.In the setting example, as long as using the 1st distance D1 and the 2nd distance D2 that are assessed as zero in table 1, it can be set in
The range of sufficient corrective force for from practicability can be assigned to paper portions P, can namely prevent paper portions P's
The upstream end P11 of part P1 is wrapping in the range of original upstream end contact position 31a deviates.
In the printer 1 of change case shown in Fig. 5, similarly, even if there is a situation where relaxations in the preceding part P2 of correction
Under, it can also inhibit the reduction to the paper portions P corrective forces assigned.In turn, it in the printer of change case 1, can avoid
Because of the conveyance load increase for the paper portions P that floating preventing portion 51 causes.Therefore, it is possible on the one hand reduce the increase of conveyance load
On the one hand the problems such as caused conveyance is bad seeks miniaturization and cost reduction of product etc..
On the other hand, exist by influences such as the mutual deviations accumulated caused by intersection or part warpage of part, and it is difficult
With control the 1st distance D1 or the 2nd distance D2 precision the case where.Especially in the printer 1 as present embodiment shown in Fig. 3
Like that, in so-called clamshell style printer, in 12 side of the cover, setting, which is floated, prevents component 5, is arranged in 11 side of printer main body
In the case of the form for correcting component 3, it is easy by influences such as part deviations.Thus, for example following form can also be set as,
That is, holding section is arranged in correction component 3 or support member 6, and the engaged part engaged with the holding section is set to the cover
12 sides, when the cover 12 is closed, the engaging by the holding section with engaged part, to position correction component 3 and float anti-
Stop part 5.According to the form, the influences such as part deviation will be not easily susceptible to, so as to which the 1st distance D1 or the 2nd distance D2 is smart
Degree is set as required size well.
Next, being illustrated to the another embodiment of the sheet carrying mechanism of the present invention.Described below
In 2nd embodiment, by with illustrated centered on the difference of embodiment shown in Fig. 2, for title with it is shown in Fig. 2
The identical inscape of title of inscape in embodiment is attached with the symbol that uses before to illustrate, and omits
Repeat description.
Fig. 7 is the figure for the another embodiment for conceptually indicating the sheet carrying mechanism of the present invention.In addition, in Fig. 7
In, there is shown correct the situation that preceding part P2 is relaxed state.
The sheet carrying mechanism 10' of another embodiment is compared with sheet carrying mechanism 10 shown in Fig. 2, main difference
Point is do not have upstream side pressing component 2.As a result, in sheet carrying mechanism 10', it is by it that floating, which prevents component 5,
Floating preventing portion 51 presses paper portions P from the sides inner surface Pi, and paper portions P is pressed against to original upstream end in contact
Position 31a, to which the angle that straight angle θ is maintained original will be smoothed out with the fingers.That is, floating prevents component 5 also to have on shown in Fig. 2
Swim the function of side pressing component 2.
According to sheet carrying mechanism 10', it is convenient to omit upstream side pressing component 2, even if correcting preceding part P2 as shown in Figure 7
For relaxed state, it can also inhibit the reduction to the paper portions P corrective forces assigned.
The present invention is not limited to the embodiments, and various changes can be carried out in the range recorded in claims
More.Even if in addition, for the constitutive requirements for only including in the record of each embodiment discussed above and each change case, also may be used
This composition important document is applied to other embodiment or other change case.
