Under situation about printing on the case paper P1, when giving paper feed roller 24 with case paper P1, first electromagnetic clutch 40 is set at off working state by case paper outlet roller 64, simultaneously second electromagnetic clutch 45 is set at duty.So, the rotary driving force of CD-ROM drive motor 26 just passes to first travelling gear 41, second electromagnetic clutch 45, first drive pulley 18, driving-belt 43, the second drive pulley 44a, main body side gear 44, record-paper case side gear 67 and driven wheel 64a successively, and case paper P1 just 24 is sent from record-paper case 60 towards paper feed roller by case paper outlet roller 64.The leading section one of this case paper P1 arrives paper feed roller 24 (being detected by not shown sensor), just allows second electromagnetic clutch 45 for off working state, by paper feed roller 24 case paper P1 is supplied to printing portion 21 thus, as described later.At this moment, case paper outlet roller 64 and the transmission action interlock to case paper P1 that paper feed roller 24 is carried out carry out driven rotation.
On the other hand, under situation about printing on the main body paper P2, when giving paper feed roller 24 with main body paper P2, first electromagnetic clutch 40 is set at duty, simultaneously second electromagnetic clutch 45 is set at off working state by main body paper outlet roller 10.So, the rotary driving force of CD-ROM drive motor 26 just passes to first electromagnetic clutch 40, second travelling gear 13, the 3rd travelling gear 14 and driven wheel 10a successively, and main body paper P2 just 24 is sent from storage chamber S2 towards paper feed roller by main body paper outlet roller 10.The leading section one of this main body paper P2 arrives paper feed roller 24, just allows first electromagnetic clutch 40 become off working state, by paper feed roller 24 main body paper P2 is supplied to printing portion 21 thus.At this moment, main body paper outlet roller 10 and the transmission action interlock to main body paper P2 that paper feed roller 24 is carried out carry out driven rotation.Like this, CD-ROM drive motor 26, first electromagnetic clutch 40, second travelling gear 13, the 3rd travelling gear 14, driven wheel 10a, main body paper outlet roller 10 and paper feed roller 24 constitute the connecting gear of extracting main body paper P2 out and send printing portion 21 to from the storage chamber S2 of printer main body portion 1.
Utilizing the described paper disc 7 of manually putting under situation about printing on the sheet-fed, allow first electromagnetic clutch 40 and second electromagnetic clutch, 45 both sides be all halted state, paper P1, P2 are not sent out from the storage chamber S1 of record-paper case 60 and the storage chamber S2 of body 2.Drive described drive roll 9a and allow drive roll 9a rotate a circle by described motor, sheet-fed is sent towards paper feed roller 24.The leading section one of this sheet-fed arrives paper feed roller 24, and drive roll 9a will no longer transmit paper owing to the existence of the notch part branch of drive roll 9a, after this just by paper feed roller 24 sheet-fed is fed to printing portion 21.
Described CD-ROM drive motor 26 can rotate and reverse, and can allow the case paper P1 return recording carton 60 that has sent printing portion 21 to thus, perhaps allows main body paper P2 return storage chamber S2.
Allowing under the situation of case paper P1 return recording carton 60, allow first electromagnetic clutch 40 and second electromagnetic clutch 45 still keep off working state constant, allow paper feed roller 24 reverse rotation when case paper P1 is fed to printing portion 21.The leading section one of case paper P1 is by paper feed roller 24, and it is constant just to allow first electromagnetic clutch 40 keep off working state, allows second electromagnetic clutch 45 become duty, allows case paper outlet roller 64 reverse rotation when sending case paper P1.So just the leading section of case paper P1 is sent back to case paper outlet roller 64 theres.
Allowing main body paper P2 return under the situation of storage chamber S2, allowing first electromagnetic clutch 40 and second electromagnetic clutch 45 still keep off working state constant, allowing paper feed roller 24 reverse rotation when main body paper P2 is fed to printing portion 21.The leading section one of main body paper P2 is by paper feed roller 24, and it is constant just to allow second electromagnetic clutch 45 keep off working state, allows first electromagnetic clutch 40 become duty, allows main body paper outlet roller 10 reverse rotation when sending main body paper P2.So just the leading section of main body paper P2 is sent back to main body paper outlet roller 10 theres.
For example, in the printing of interrupting on case paper P1,, as mentioned above, send the case paper P1 that has released back to record-paper case 60 with when being placed on the sheet-fed manually put in the paper disc 7 or the main body paper P2 in the storage chamber S2 and feeding to printing portion 21 and print.Also have, when case paper P1 will being replaced by new case paper P1, also the case paper P1 that releases will be sent back in the record-paper case 60.
Top at the record-paper case installed surface (face of printer front side) of described printer main body portion 1 is formed with in order to case paper P1 is introduced the introducing peristome 1a (with reference to figure 6, Fig. 8 and Figure 14) in the printer main body portion 1.This introducing peristome 1a is formed into the upper part of the described switch door leaf 4 that is positioned at its downside from the height and position that roughly equates with record-paper case 60 tops (case paper described later is drawn peristome 60c) on above-below direction.In printer main body portion 1, be formed with the introducing transfer path to the part of paper feed roller 24 from introducing peristome 1a, this introducings transfer path in order to will introduce from this introducing peristome 1a printer main body portion 1 interior case paper P1 guide paper feed roller 24 into.Printing surface one side of case paper P1 on this introducing transfer path is provided with two guide rollers 12,12 as the guiding parts (with reference to figure 2, Fig. 3 and Figure 14) that this case paper P1 is led.Be provided with guiding parts 28 in a side opposite with printing surface, this guiding parts 28 extends near the guide roller 12 of printer rear side from introducing peristome 1a, jointly case paper P1 is led with two guide rollers 12,12.The purpose that this guiding parts 28 is set is, when the leading section of case paper P1 moves towards paper feed roller 24 through described introducing transfer path, guarantees that the leading section of this case paper P1 is not partial to the downside of this introducing transfer path.
The printing surface of case paper P1 on described each guide roller 12 and the described introducing transfer path contact and with the rotation (driven rotation) linkedly of moving of this case paper P1.The peripheral part of this each guide roller 12 is made of elastomeric element.That is to say that each guide roller 12 is the different rollers of inner periphery and the outer periphery material on its section, the hard part in week (parts that formed by hard resin, metal etc.) whole enclosed and all surrounds and cover in described elastomeric element will constitute.In addition, the section integral body of each guide roller 12 is made of elastomeric element and also can.
Described introducing transfer path is bending, and promptly the printing surface of the case paper P1 on this introducing transfer path is concavity along the length direction of this introducing transfer path.Generally, watch, introduce transfer path and be located on the tangent line (straight line that is connected the two ends of introducing transfer path) of connecting box paper outlet roller 64 and paper feed roller 24 from the printer left and right directions.But in the present embodiment, because be formed with from manually putting the transfer path of paper disc 7, so, be difficult to the introducing transfer path is located on the described tangent line from spatial relationship to paper feed roller 24 at the upside of introducing transfer path.Therefore, allow and introduce the length direction bending of transfer path along this introducing transfer path, when assurance was watched from the printer left and right directions, the mid portion of introducing the length direction of transfer path was positioned at the downside (side opposite with the printing surface of case paper P1) of described tangent line (described straight line).
Here, as described later, when printing, described paper feed roller 24 is carrying case paper P1 discontinuously, so this paper feed roller 24 carries out its rotation repeatedly and stops.Therefore the increase and decrease that just can on the case paper P1 on the described introducing transfer path, produce tension force.(paper feed roller begins to rotate when tension force increases, and beginning is during towards printing portion one side carrying case paper), because the case paper P1 that described introducing transfer path is crooked and crooked will be towards described guide roller 12,12 1 side shiftings, very big impulsive force will act on the guide roller 12,12.In the present embodiment, each guide roller 12 is provided with the impulsive force absorbent portion, absorbs at least a portion owing to the tension force that acts on the case paper P1 increases the described impulsive force that acts on this guide roller 12.
Particularly, the impulsive force absorbent portion of each guide roller 12 is made of the described elastomeric element of the peripheral part that constitutes this guide roller 12, utilizes the compression of this elastomeric element to absorb described impulsive force.In the present embodiment, this elastomeric element is made by the foaming urethanes.In order fully to absorb described impulsive force, allow the foaming rate of the foaming urethanes of making this elastomeric element greater than promptly the bubble foaming rate of urethanes of the elastomeric element material of described main body paper outlet roller 10, so that compression takes place this elastomeric element easily.Two guide rollers 12 are arranged on the length of described introducing transfer path roughly on the position of trisection, and impact force action about equally is on two guide rollers 12.
If the rotary speed of paper feed roller 24 reduces and is tending towards stopping, the tension force that then acts on the case paper P1 will reduce.So, the compress variation of the elastomeric element of each guide roller 12 will diminish.In addition, even when paper feed roller 24 stops fully, tension force also can act on the case paper P1, and each guide roller 12 just contacts (elastomeric element of guide roller 12 has a compression a little) with case paper P1.
