Next, when coil paper R is set up, the action of the printing equipment 1 when the end of coil paper R being detected is described.

Here, for coil paper R, exist as shown in Fig. 4 (A), relative to core R3, the situation waiting the end of coil paper R to be fixed by stickup, and as shown in Fig. 4 (B), relative to core R3, the loose situation of end of coil paper R.

Further, printing equipment involved by present embodiment 1, no matter when the coil paper R of which kind of type is set up, all utilizes tension force control lever 13, positively detects its end.

Fig. 5 is the flow chart of the action representing printing equipment 1.

Printing equipment 1, due to printed medium printing images, is therefore carried motor 31 in driving the 1st and during printed medium is carried on throughput direction F, performs the process shown in flow chart of Fig. 5.

Here, printing equipment 1, during making printed medium carry on throughput direction F according to the printing of image, monitors the rotation status of tension force control lever 13.Further, be maintained at the mode of N2 " ep " according to the value of the rotation status representing tension force control lever 13, adjust transporting velocity.The value of N2 is preset under the viewpoint of giving suitable tension force to printed medium in order to printing images.

In addition, at printing equipment 1, coil paper R is set up.

During conveying coil paper R2 is carried on throughput direction F, the value of control part 50 to the rotation status representing tension force control lever 13 is less than N3 " ep " (N3 < N2) (step SB1), or is greater than N4 " ep " (N4 > N2) (step SB2) and monitors.

When being less than N3 " ep " (step SB1: yes), control part 50 is the mode of N2 " ep " according to the value of the rotation status representing tension force control lever 13, the transporting velocity (step SB3) of adjustment conveying coil paper R2 within certain period.

Next, whether control part 50, by the adjustment of transporting velocity, is greater than N3 " ep " to the value of the rotation status representing tension force control lever 13 and differentiates (step SB4).

By the adjustment of the transporting velocity of period certain in step SB3, when the value of the rotation status representing tension force control lever 13 is greater than N3 " ep " (step SB4: yes), processing sequence is turned back to step SB1 by control part 50.

The reason that can judge like this is as follows.

That is, along with the consumption of coil paper R, when carrying the end of coil paper R2 to be separated from core R3, the load being applied to tension force control lever 13 reduces, and the degree of the rotation of tension force control lever 13 reduces.Further, no matter how to adjust the transporting velocity of conveying coil paper R2, this state does not change.Accordingly, even if the adjustment of the transporting velocity during carrying out necessarily, when representing that the value of the rotation status of tension force control lever 13 is also not more than N3 " ep ", above-mentioned purport can be judged as.In addition, under the viewpoint of judgement of carrying out step SB5, the value of N3 is set by simulation in advance, test etc.

After the judgement of step SB5, control part 50, based on this judgement, performs corresponding process (step SB6).Such as, control part 50 stops the process involved by printing, and informs that coil paper R is the coil paper of the loose type of its end for core R3 to user, and the paper of coil paper R will be used up.

On the other hand, during being carried on throughput direction F by conveying coil paper R2, when the value of the rotation status representing tension force control lever 13 is greater than N4 " ep " (step SB2: yes), control part 50 carries out following process.That is, control part 50 is the mode of N2 " ep " according to the value of the rotation status representing tension force control lever 13, within certain period, and the transporting velocity (step SB7) of adjustment conveying coil paper R2.

Next, whether control part 50, by the adjustment of transporting velocity, is less than N4 " ep " to the value of the rotation status representing tension force control lever 13 and differentiates (step SB8).

By the adjustment of the transporting velocity of the certain period in step SB7, when the value of the rotation status representing tension force control lever 13 is less than N4 " ep " (step SB8: yes), processing sequence is turned back to step SB1 by control part 50.

On the other hand, even if carrying out the adjustment of transporting velocity of the certain period in step SB7, when representing that the value of the rotation status of tension force control lever 13 is also not less than N4 " ep " (step SB8: no), control part 50 is judged as following state (step SB9).That is, control part 50 is judged as that the coil paper R be set up is the coil paper of the type that its end is fixed for core R3, is that all coil paper R are pulled out by from core R3, should stops the state of the conveying of coil paper R.

The reason that can judge like this is as follows.

That is, latter end is fixed on to the coil paper R of core R3, under the state that all coil paper R are drawn out, when carrying out coil paper R to the conveying of throughput direction F, increase the load that tension force control lever 13 applies, the degree of the rotation of tension force control lever 13 increases.Further, as long as coil paper R2 will be carried to the conveying of throughput direction F side, this state will not just change.Accordingly, even if the adjustment of the transporting velocity during carrying out necessarily, when representing that the value of the rotation status of tension force control lever 13 is also not less than N4 " ep ", above-mentioned purport can be judged as.In addition, under the viewpoint of judgement of carrying out step SB9, the value of N4 is set by simulation in advance, test etc.

After the judgement of step SB9, control part 50, based on this judgement, performs corresponding process (step SB10).Such as, control part 50 stops the process involved by printing, and informs that coil paper R is the coil paper of the type that its end is fixed for core R3 to user.
