Shown in symbol P1 among Fig. 3, the roll paper 110 from be contained in roll paper support 2 is removed coiling in the bottom of cylinder and record-paper 112 is forwards pulled out, and draws in paper inlet 48.For record-paper 112 is bent upwards for the time being, be provided with the bend 26 that upwards is convex in the inside of roll paper support 2, record-paper 112 is jumped over bend 26 and is arrived agley with paper inlet 48.In addition, in the inside of roll paper support 2, be formed with receiving space 27 at bend 26 with above between the paper inlet 48.Receiving space 27 is the spaces that under situation about will reel back from the record-papers 112 that are drawn into printer main body 4 inside with paper inlet 48 for the time being, are used to accommodate the amount of being reeled back.

The printer 1 that so constitutes can transmit changer lever 16 (with reference to Fig. 4) and optionally will use printing word or image etc. as recording medium by the record-paper 112 of roll paper support 2 supplies or the continuous paper of being supplied with by continuous paper supply unit 6 120 through operation.If the transmission changer lever 16 that makes Fig. 4 in face of side be that topple over the front side of printer 1; Then the rotation of platen 41 generation under the dynamic action of carrying motor (diagram slightly) is delivered to tractor driving shaft 61; Tractor driving shaft 61 synchronously rotate with platen 41 and press down downwards with roll paper by be pressed on the platen 41 by pressure roller 50, make by pressure roller 50 and leave from platen 41.In addition, transmit changer lever 16 inclination rearward and fall, then press pressure roller 50 crimping platen 41 once more, and the blocking revolving force has only platen 41 rotations to the transmission of tractor driving shaft 61, can't help continuous paper supply unit 6 conveying continuous papers 120 if make.In this embodiment; In the wheel row mechanism on being arranged at right side frame 18 (diagram slightly); By carrying motor (diagram slightly) rotation and support under the operation effect of transmitting changer lever 16, to move, perhaps do not mesh with the spur gear engagement that is installed on the tractor driving shaft 61 for the movable spur gear that can move.

And, as shown in Figure 3, the outlet that outlet that record-paper 112 is supplied with to printer main body 4 from roll paper support 2 and continuous paper supply unit 6 are supplied with continuous paper 120 to printer main body 4 all with enter the mouth with paper 48 opposed.Therefore, the structure of printer main body 4 is service recorder paper 112 and continuous paper 120 commonly, therefore need not change the mechanism of printing according to the kind of recording medium.

Recording medium is being switched to continuous paper 120 or switches under the situation of record-paper 112 from continuous paper 120 from record-paper 112, and execution will be transported to the recording medium in position or its place ahead of print head 43 towards the reverse conveying action of oppositely carrying with paper inlet 48.

Also can utilize the control of control substrate 57 to make conveying motor (diagram slightly) counter-rotating, make

platen

41 and 61 counter-rotatings of tractor driving shaft thus, oppositely carry action thereby carry out this.Specifically, indicated in the operation of the switch of demonstration/operating portion 13 under the situation of reverse conveying action, control substrate 57 makes carries motor counter-rotating ormal weight.Under the situation of record-paper 112, the front end of recording medium that is positioned at the position of ejection port 14 or print head 43 turns back to the position by pressure roller 50 under the counter-rotating effect of platen 41.Then; The record-paper 112 that makes 25 rotations of roll paper coiling knob and will be drawn in the receiving space 27 is wound on the roll paper 110; Make the leading section of record-paper 112 be positioned at than after the roll paper outlet 20C (Fig. 8) that states lean on the position of the inboard of roll paper support 2, not become the conveying obstacle of continuous paper 120.Demonstration/operating portion 13 is as having the switch portion of switch and bring into play function at least, and said switch is used to make the action of reversing of the conveying mechanism with platen 41.At this, conveying mechanism also can comprise tractor driving shaft 61.

On the other hand, under the situation of continuous paper 120, reverse and reverse the conveying through platen 41 and tractor driving shaft 61.Following deliver amount is only carried out in this reverse conveying, that is, after the leading section of continuous paper 120 was detected by paper detector 53, leading section was in the deliver amount till the position that arrives the conveying obstacle that does not become record-paper 112 between the tractor unit 60.If stop continuous paper 120 in this position, then continuous paper 120 keeps being assembled in the state of tractor unit 60.Therefore, under the situation of wanting to use continuous paper 120 once more,, so do not need on tractor unit 60, to be provided with again continuous paper 120 only through 61 rotations of tractor driving shaft just can be carried continuous paper 120 to platen 41 sides, from but easily.Also have, wanting under the situation that continuous paper 120 is unloaded from continuous paper supply unit 6 as long as further reverse tractor driving shaft 61.

In addition, under the state that printer 1 stops, through manually making paper feeding knob 46 (second knob) to opposite spin, reverse conveying recording medium.At this moment, the front end of recording medium also turns back to by the position before the pressure roller 50.Turn back to by pressure roller 50 recording medium before and can under manual action, be pulled, under the situation of reverse feeding recordable paper 112, make roll paper coiling knob 25 rotations of roll paper support 2 and make roll paper 110 rotations, coiling record-paper 112 gets final product.In addition, in printer 1,, the tractor driving shaft 61 of continuous paper supply unit 6 is reversed linkedly with platen 41 through the counter-rotating of conveying motor (diagram slightly) or the operation of paper feeding knob 46.Therefore, under the situation of reverse conveying continuous paper 120, can utilize the counter-rotating of tractor driving shaft 61 to make continuous paper 120 turn back to the position of tractor unit 60.

So, turn back at least with before the paper inlet 48 through making the side in record-paper 112 or the continuous paper 120, can print with the opposing party's recording medium from sending into printer main body 4 with paper inlet 48.Therefore, in printer 1, can switch service recorder paper 112 and continuous paper 120 through simple operation.

At this,, have and be used to make the reverse automatically demonstration/operating portion 13 of switch of action of the conveying mechanism that comprises platen 41 to be arranged on the right side of printer 1 like Fig. 1 and shown in Figure 2.With respect to this, the roll paper coiling knob 25 (first knob) of the roll paper 110 that is contained in roll paper support 2 of being used for reeling is like Fig. 1, Fig. 2 and the left side that is arranged at printer 1 shown in Figure 6.

Therefore; Operation utilizing demonstration/operating portion 13 is oppositely carried under the situation of action automatically; The operator of printer operation 1 is with right-hand operated demonstration/operating portion 13; And make 25 rotations of roll paper coiling knob and make roll paper 110 rotations with left hand, thereby can be wound on the record-paper 112 that reverse conveying action is returned down.

In addition; Manually oppositely carry under the situation of action in the operation that utilizes paper feeding knob 46; The operator makes 46 rotations of paper feeding knob and makes platen 41 counter-rotatings with the right hand; And make 25 rotations of roll paper coiling knob and make roll paper 110 rotations with left hand, thereby can be wound on the record-paper 112 that reverse conveying action is returned down.

Therefore that is, in printer 1, can the conveying mechanism that comprise platen 41 reversed in the action, manual coiling record-paper 112 can be at the untapped record-paper 112 of the situation recover that does not cause record-paper 112 paperboards.
