Abstract

<P>PROBLEM TO BE SOLVED: To provide a medium to be conveyed which is reliably conveyed, and a recording device. <P>SOLUTION: An elastic tape member 58 is pasted on the reverse side of the tray 50 in which an optical disc is set. A discharging roller which is rotationally driven conveys the tray 50 by a force of friction with the tape member pasted on the reverse side of the tray 50 when the tray is discharged during label printing. At this time, because the adhesion between the tray 50 and the discharging roller increases by means of the tape member pasted on the reverse side of the tray 50 and the tray conveyance force becomes larger due to a caterpillar effect, the tray 50 can be reliably discharged. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a medium to be transported which is transported by the rotation of a pressure-contact roller and a recording apparatus.

  2. Description of the Related Art Conventionally, there is known an ink jet printer that enables label printing by ejecting ink droplets onto a label surface of an optical disk such as a CD or a DVD (see, for example, Patent Document 1). As a procedure for performing label printing, first, a user sets a thin plate-like body such as an optical disc on a plate-shaped tray and places it on a stacker provided at the front of the printer. The tray placed on the stacker is nipped between the transport driving roller and the transport driven roller, and is transported by the transport driving roller that is rotationally driven. Then, the ink jet recording head inside the printer discharges ink toward the thin plate-like body set on the tray, whereby printing is performed on the label surface of the optical disc, and the tray after printing is stacked by a discharge drive roller. To be discharged.

  Here, in order to discharge the tray, it is necessary to apply a transport force larger than the transport resistance received due to friction between the tray and the stacker to the tray. For this reason, in the ink jet printer described in Patent Document 1, the transport resistance received by the tray is reduced by forming ribs along the tray discharge direction on the stacker.

JP 2007-30304 A

  However, in the inkjet printer described in Patent Document 1, the tray conveying force may be insufficient due to insufficient frictional force between the discharge drive roller and the tray.

  In particular, when label printing is repeated, the abrasion powder generated from the tray or the like with the mechanical operation adheres to the discharge drive roller, thereby reducing the frictional force between the discharge drive roller and the tray, As a result, the discharge driving roller is idled and the tray cannot be properly discharged.

  SUMMARY An advantage of some aspects of the invention is to solve at least one of the problems described above, and the invention can be implemented as the following forms or application examples.

  Application Example 1 A transported medium that is pressed against a driving roller and transported by rotation of the driving roller, and is provided on a transported medium main body and a surface of the transported medium main body facing the driving roller. A medium to be transported comprising an elastic layer.

  According to this configuration, since the driving roller is pressed into contact with the elastic layer provided on the transported medium main body, the elastic layer in the pressed portion is deformed, and the driving roller is fitted into the deformed recess so as to be in close contact. Therefore, the transport force acting on the transported medium is increased by the rotational driving of the drive roller. That is, the transport force of the transported medium can be increased by the so-called caterpillar effect. Therefore, the medium to be transported can be transported more reliably.

  Further, an elastic layer is sandwiched between the driving roller and the transported medium main body, so that the driving roller and the transported medium main body are not in direct contact with each other. Thereby, since generation | occurrence | production of the abrasion powder from a to-be-conveyed medium main body is prevented, the conveyance force fall of the to-be-conveyed medium by abrasion powder adhering to a drive roller can be suppressed.

  Application Example 2 In the transported medium, the transported medium is characterized in that the elastic layer has elasticity larger than that of the transported medium main body.

  According to this configuration, compared to the case where no elastic layer is provided, the transport force is increased by the caterpillar effect, so that the transported medium can be transported more reliably.

  Application Example 3 In the transported medium, in the transported medium, the elastic layer is formed by a tape member attached to a facing surface of the transported medium main body.

  According to this configuration, since the transport force acting on the transported medium is increased by the elasticity of the tape member, the transported medium can be transported more reliably. In addition, the elastic layer can be formed by a simple method of attaching the tape member to realize reliable conveyance of the medium to be conveyed.

  Application Example 4 In the transported medium, the transported medium is characterized in that the elastic layer is an insulator.

  According to this configuration, when the medium to be transported is transported by the rotational driving of the driving roller, the elastic layer that is an insulator is charged by friction with the driving roller or the like. As a result, even if wear powder is generated from the transported medium main body or the like, the wear powder is attracted to the elastic layer, so that it is possible to prevent a decrease in transport force of the transported medium due to the wear powder adhering to the drive roller. it can.

  Application Example 5 In the transported medium, the transported medium body is a tray on which a thin plate-like body can be set.

  According to this configuration, the set thin plate-like body can be transported together with the transported medium.

  Application Example 6 The medium to be transported, a driving roller that is pressed against the medium to be transported and rotationally driven, and a recording head that discharges droplets to the medium to be transported that is transported by the driving roller; A recording apparatus comprising:

  According to this configuration, it is possible to more reliably perform printing on the transported medium by transporting the transported medium more reliably and ejecting ink onto the transported medium. For example, when a thin plate such as an optical disk is set on the medium to be transported, it is possible to perform printing on the thin plate more reliably.

  An example according to an embodiment of the present invention will be described with reference to the drawings. Hereinafter, an outline of an inkjet printer (hereinafter referred to as “printer”) will be described with reference to FIG. 1 which is an external perspective view of the printer.

  As shown in FIG. 1, a printer (recording device) 1 includes a feeding device 2 on which recording paper (hereinafter referred to as “paper P”) can be set, and a recorded paper P and tray 50 (see FIG. 3). ) Is discharged. The printer 1 is capable of ink-jet recording on a tray (transported medium) 50 and a transported medium having high rigidity such as thick board paper. Label printing on the label surface of an optical disc such as a DVD-R is possible.

  The feeding device 2 is provided at the rear portion of the printer 1, and the discharging device 3 is provided at the front portion of the printer 1. The space between the feeding device 2 and the discharging device 3 is covered with a case-like housing 11.

A stacker 13 configured to be switchable is provided. The stacker 13 includes a stacker body and a sub stacker (not shown), and is rotatable around a rotation shaft at the lower part of the stacker body. In a state where the stacker 13 is opened by being rotated to the front side of the printer, the stack surface of the paper P is formed by pulling out the sub stacker from the stacker body. The feeder 1, the discharge device 3, the stacker 13, the housing 11, and the cover 12 described above constitute the external appearance of the printer 1.

  The stack surface of the stacker 13 is provided with ribs for reducing transport resistance when transporting the paper P and the tray 50 and a tray guide (not shown) for guiding the tray 50 to be set. Yes.

  Next, the internal configuration of the printer 1 will be described. FIG. 2 is a side view showing the internal configuration of the printer 1. In the following description, the front side of the printer is referred to as the “downstream side” of the paper transport path, and the rear side of the printer is referred to as the “upstream side”. At this time, the direction from the upstream side to the downstream side is the paper transport direction, that is, the sub-scan feed direction. Hereinafter, the configuration from the upstream side along the transport direction will be described in order.

  First, the feeding device 2 located on the most upstream side will be described. As shown in FIG. 2, the feeding device 2 includes a hopper 19, a feeding roller 20, a retard roller 21, and a return lever 22. The hopper 19 is formed of a plate-like body and is configured to be swingable around an upper swing fulcrum (not shown). As the plate-like body swings around the swing fulcrum, the paper P supported in an inclined posture on the hopper 19 is pressed against or separated from the feed roller 20. The feeding roller 20 has a shape in which the cross section in the rotation axis direction is substantially D-shaped. With the arc portion of the substantially D-shaped feeding roller 20 in pressure contact with the uppermost sheet P, the sheet P is fed downstream by the rotation of the feeding roller 20. In addition, when the fed paper P is being transported by a transport roller, which will be described later, the flat portion of the substantially D-shaped feed roller 20 faces the paper P, and the paper P on the hopper 19 is fed from the paper P. The conveying load caused by the feeding roller 20 is prevented from being generated by separating 20.

  The retard roller 21 is disposed so as to come into contact with the feeding roller 20 and frictionally separates the uppermost sheet P from the lower layer sheet P when the sheet P is multi-fed by the feeding roller 20. It has become. The return lever 22 is provided so as to be rotatable, and is used to return the next and subsequent sheets P to be fed to the hopper 19.

  Further, on the downstream side of the feeding device 2, detection means (not shown) for detecting the passage of P, a feeding posture of the paper P is formed, and contact of the paper P with the feeding roller 20 is prevented. A guide roller 26 is provided to reduce the conveyance load.

  A conveyance roller pair 29 is provided further downstream of the feeding device 2. The transport roller pair 29 includes a transport drive roller 30 that is rotationally driven by a motor, and a transport driven roller 31 that is driven to rotate while being in pressure contact with the transport drive roller 30. On the outer peripheral surface of the transport driving roller 30, a layer in which wear-resistant particles are dispersed substantially uniformly is formed. The transport driven roller 31 is composed of a plurality of rollers whose outer peripheral surface is made of a low friction material such as an elastomer. Each roller of the transport driven roller 31 is freely rotated at the downstream end of the upper 24 of the paper guide. It is pivotally supported. The shaft 24a is supported by the main frame 23 so that the paper guide top 24 is swingable about the shaft 24a with respect to the paper transport path, and the transport driven roller 31 is transported by the coil spring 25. The roller 30 is urged in a direction in which it is pressed against the roller 30.

  The sheet P fed to the pair of transport rollers 29 by the feeding device 2 and the tray inserted from the front side of the device as will be described later are transported while being nipped by the transport drive roller 30 and the transport driven roller 31. As the roller 30 rotates, it is conveyed to the recording unit 32 on the downstream side.

  The recording unit 32 includes an inkjet recording head (hereinafter referred to as “recording head”) 36 and a paper guide lower portion 37 that faces the recording head 36. The recording head 36 is provided at the bottom of the carriage 33. The carriage 33 is configured to reciprocate in the main scanning direction by a drive motor (not shown) while being guided by a carriage guide shaft 34 extending in the main scanning direction. The carriage 33 has an independent ink cartridge (not shown) for each of a plurality of colors inside the cover 35, and supplies ink from the ink cartridge to the recording head 36. The lower paper guide 37 is for defining the distance between the paper P and the recording head 36, and a rib is formed on the surface facing the recording head 36 and a recess for discarding ink is formed. . This concave portion is a portion for discarding ink, and so-called borderless printing is executed by discharging the ink to an area off the edge of the paper P.

  A discharge device 3 is provided on the downstream side of the recording head 36. The discharge device 3 includes a guide roller 43, a discharge roller pair 40, a paper discharge frame unit 45, and a stacker 13.

  The guide roller 43 functions to prevent the paper P from being lifted from the paper guide bottom 37 and to keep the distance between the paper P and the recording head 36 constant.

  The discharge roller pair 40 includes a discharge drive roller (drive roller) 41 that is rotationally driven by a motor, and a discharge driven roller 42 that is driven to rotate in pressure contact with the discharge drive roller 41. The discharge drive roller 41 is composed of a plurality of rubber rollers provided in the axial direction of the shaft body that is rotationally driven. The discharge driven roller 42 is configured such that a plurality of toothed rollers provided to be paired with the rubber roller of the discharge drive roller 41 are pivotally supported by the paper discharge frame unit 45. The paper P recorded by the recording unit 32 is discharged to the stacker 13 when the discharge drive roller 41 is rotationally driven while being nipped by the discharge drive roller 41 and the discharge driven roller 42.

  The paper discharge frame unit 45 pivotally supports the discharge driven roller 42 so that the discharge driven roller 42 can be switched between a contact position where the discharge driven roller 42 contacts the discharge driving roller 41 and a separation position where the discharge driven roller 42 is separated from the discharge driving roller 41. Is provided. This contact position is a position that is taken during normal printing, and the separation position is a position that prevents the discharge driven roller 42 from damaging the label surface of the optical disc during label printing. Further, the paper discharge frame unit 45 rotatably supports the pressing roller 44 at a position downstream of the discharge driven roller 42. The pressing roller 44 presses the tray 50 toward the discharge driving roller 41 at the separation position.

  The above-described stacker 13 is provided on the downstream side of the paper discharge frame unit 45, and when the stacker 13 is in an open state, a linear paper transport path from the upstream side of the transport roller pair 29 to the stacker 13 is formed. The When performing label printing, the tray on which the optical disk is set is manually inserted from the tray guide of the stacker 13 on the downstream side of the linear sheet transport path toward the rear side (upstream side) of the apparatus. And set. FIG. 3 shows a state in which a tray is set on the conveyance path of the printer 1. When setting the tray 50, the user inserts the tray 50 into the stacker 13 at the rear of the printer 1, and feeds the tray 56 so that it slides on the stacker 13 to a position where the leading end 56 abuts against the conveying roller pair 29 and is nipped. 3 is set. The set tray 50 is subjected to ink jet recording by the recording head 36 while being transported along a linear sheet transport path.

  Next, the configuration of the tray 50 as a transported medium will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing a configuration of a surface (hereinafter referred to as “tray surface”) facing the discharge driven roller 42 in a set state. FIG. 5 is a diagram illustrating a configuration of a surface (hereinafter, referred to as “tray back surface”) that faces the discharge driving roller 41 in the set state.

  As shown in FIG. 4, the tray main body (conveyed medium main body) 51 of the tray 50 has a substantially rectangular plate shape, can be nipped by the conveyance driving roller 30 and the conveyance driven roller 31, and is conveyed and driven. The shape is such that sub-scan feed is possible as the roller 30 rotates. The tray main body 51 having the above-described shape is provided with a set portion 52. The set part 52 is a circular concave part so that the optical disk can be fitted therein, and a convex part 53 is formed at the center of the set part 52. When the optical disc is set in the set portion 52, the center hole of the optical disc is fitted into the convex portion 53, whereby the position of the optical disc in the set portion 52 is determined. The two holes 54 formed around the set portion 52 are for taking out the optical disc.

  4 and 5 corresponds to the transport direction of the tray 50. When the tray 50 is inserted into the linear transport path via the open stacker 13, the top and bottom of FIG. The upper part of the tray 50 in the drawing is inserted as a tip. That is, the tray 50 is set so that the tray 50 is inserted into the tray guide of the stacker 13 with the front end 56 as the head. A tongue piece 57 that protrudes in the insertion direction of the tray 50 is formed at the front end portion 56 of the tray 50. The tongue piece portion 57 is tapered toward the tip, and the bottom surface thereof forms a flat surface together with the bottom surface of the tray main body 51. The front end portion 56 of the tray 50 is also formed to taper toward the front end in the same manner as the tongue piece portion 57.

  Next, the configuration of the back side of the tray 50, that is, the side facing the discharge drive roller 41 will be described. As shown in FIG. 5, a sheet-like tape member 58 is affixed to the front side of the tray main body 51 on the back side of the tray 50. The tape member 58 has a configuration in which an adhesive layer is laminated on an elastic tape base material, and is attached to the back side of the tray body 51 by the adhesive layer. Accordingly, a layer structure having elasticity by the tape member 58, that is, an elastic layer is formed on the back surface of the tray 50.

  Here, the tray body 51 of the present embodiment is formed by integrally forming an ABS resin. As the tape member 58, a material having greater elasticity than that of the tray main body 51 is selected. As a result, a Damplon (registered trademark) tape is used as the tape member 58. The tape member 58 is an elastic member having elasticity larger than that of the tray body 51 and is also an insulator having a smoother surface than the tray body 51.

  Further, the tape member 58 is affixed to a predetermined range where the discharge driving roller 41 contacts when the tray is discharged. Although details will be described later, when the tray is discharged, the tray 50 in the set state shown in FIG. 3 is discharged to the outside of the printer by the discharge driving roller 41, so that the tape member is in a range where the discharge driving roller 41 abuts when the tray is discharged. 58 is affixed. That is, as shown in FIG. 3, the tape member 58 is affixed in a range extending from the position facing the discharge drive roller 41 to the front end portion 56 in the set state.

  Next, the label printing operation performed by the printer 1 described above will be described. In label printing, first, the user sets an optical disk on the setting unit 52 of the tray 50 and opens the stacker 13 so as to be tilted forward of the apparatus.

  Then, the user inserts the tray 50 into the tray guide of the stacker 13 with the front end portion 56 of the tray 50 at the head, and sends the tray 50 to a position where the front end portion 56 abuts against the pair of conveying rollers 29. The set state. At this time, when the paper discharge frame unit 45 takes the separation position, the discharge driven roller 42 is separated from the discharge drive roller 41, and the tray 50 that contacts the discharge drive roller 41 is prevented from touching the discharge drive roller 41. The optical disc is not damaged during printing.

  Here, in order to perform sub-scan feed of the tray 50 by the rotation of the transport driving roller 30, the front end portion 56 of the tray 50 is moved between the transport driving roller 30 and the transport driven roller 31 in pressure contact with the transport driving roller 30. Although it is necessary to interpose, the tongue part 57 of the shape which tapers toward the front-end | tip part is formed in the front-end | tip part 56 of the tray 50. As shown in FIG. Therefore, when the tray 50 is sent out toward the transport driving roller 30 and the transport driven roller 31, first, the tongue piece portion 57 enters between the transport driving roller 30 and the transport driven roller 31. 50 leading end portions 56 enter between the transport driving roller 30 and the transport driven roller 31. As a result, the tray 50 is nipped by both rollers of the conveying roller pair 29 only by the user applying a small force.

  When the printer 1 receives an instruction to start label printing from an external computer (not shown) with the tray 50 set, the conveyance drive roller 30 and the discharge drive roller 41 rotate in synchronization. Then, the tray 50 nipped by the transport driving roller 30 and the transport driven roller 31 is transported upstream from the recording head 36. Then, the conveyance drive roller 30 and the discharge drive roller 41 rotate in the opposite directions while being synchronized, and convey the tray 50 from the upstream position toward the downstream side, and the optical disk set on the tray 50 being conveyed. Label printing is performed by the recording head 36 ejecting ink toward the label surface.

  When ink jet recording is performed on the label surface of the optical disc, the transport driving roller 30 and the discharge driving roller 41 rotate in synchronization with each other so that the tray 50 is sent further downstream, so that the tray 50 is set as shown in FIG. Return to the state position. Thereafter, the conveyance drive roller 30 is in a non-contact state with respect to the tray 50, and the tray 50 is moved to the outside of the printer only by the rotation of the discharge drive roller 41, that is, the frictional force acting between the discharge drive roller 41 and the tray 50. To discharge.

  The state of the tray 50 at the time of discharge is shown in FIG. As described above, since the tape member 58 attached to the back surface of the tray 50 has elasticity, the tray 50 is pressed against the discharge driving roller 41 by the pressure from the pressing roller 44. At this time, as shown in FIG. 6, the tape member 58 is slightly recessed, and the discharge driving roller 41 is rotated so as to be fitted in the recess, whereby the tray 50 is sent out. Thus, since the adhesiveness between the discharge drive roller 41 and the tray 50 is enhanced by the tape member 58 attached to the back surface of the tray 50, the frictional force F acting between the discharge drive roller 41 and the tray 50 due to the so-called caterpillar effect. Becomes larger.

  Here, the measurement results of the frictional force acting on the tray 50 are shown in Table 1. In Table 1, the frictional force acting on the tray to which the tape member 58 is not attached (that is, the tray main body 51, hereinafter referred to as “conventional tray”) and the tray 50 to which the tape member 58 is attached (hereinafter referred to as “main tray”). The frictional force acting on the tray is indicated by a standardized value with the frictional force acting on the tray as “100”. In this case, as shown in Table 1, the frictional force acting on the main tray 50 is “114.5”, which is an improvement of 14.5% in frictional force compared to the conventional tray. Thus, it was confirmed that the frictional force F acting on the tray 50 is increased by providing the tape member 58 on the back surface of the tray 50.

  Table 2 shows the measurement results of the tray conveying force at the time of ejection. Note that “X” in Table 2 indicates the distance from the set position to the downstream side, where X = 0 is the position of the leading end 56 of the tray in the set state (FIG. 3). reference). In Table 2, for each tray position where the position of the tray front end portion 56 is X = 0 mm, 30 mm, 40 mm, and 50 mm, the tray conveying force acting on the conventional tray is set to “100”, and the tray conveying force acting on the main tray 50 is set. Is a normalized value. According to the results in Table 2, the tray conveyance is 25.0% at the set position X = 0 mm, 37.0% at X = 30 mm, 54.1% at X = 40 mm, and 12.2% at X = 50 mm. There is an improvement in power. Thus, by providing the tape member 58 on the back surface of the tray 50, it was confirmed that the tray conveying force was improved at each tray position during discharge.

  According to the printer 1 described above, the following effects can be obtained.

  (1) By attaching the tape member 58 to the back side of the tray 50 and forming an elastic layer, the frictional force acting on the tray 50 is increased as shown in Table 1, and the tray is conveyed as shown in Table 2. Since the force increases, the tray 50 can be reliably discharged. In particular, in the printer 1 of the present embodiment, when the tray 50 is discharged, there is a section in which the tray 50 is transported only by the driving force of the discharge driving roller 41 without receiving the force from the transport driving roller 30, but this section is also sufficient. The tray conveying force can be ensured.

  (2) Regarding the range where the tape member 58 is pasted, the label body printing was repeatedly performed because the tray main body 51 and the rollers such as the transport driving roller 30 and the discharge driving roller 41 are not in direct contact with each other. Sometimes, the amount of wear powder generated as the tray 50 rubs against the rollers is reduced. Thereby, the fall of the conveyance force by abrasion powder adhering to the discharge drive roller 41 is suppressed, and durability of the printer 1 regarding tray conveyance can be improved.

  (3) Since the tape member 58 is an insulator, when the label printing is repeatedly performed, the tape member 58 is charged and the abrasion powder is adsorbed by the tape member 58. Accordingly, a decrease in the conveyance force due to the abrasion powder adhering to the discharge drive roller 41 is suppressed, and the durability of the printer 1 related to tray conveyance can be enhanced.

  (4) By attaching the tape member 58 to the back surface of the tray, the conveyance resistance when the tray 50 slides on the rib on the stacker 13 is reduced. For this reason, the tray 50 can be discharged more reliably.

  (5) Without changing the configuration of the printer 1, it is possible to increase the tray conveying force by a simple method of sticking the tape member 58 to the tray body, thereby realizing reliable tray conveyance.

  Embodiments of the transported medium and the recording apparatus are not limited to the embodiments described above, and various modes can be employed. Hereinafter, modified examples will be described.

  (Modification 1) In the above embodiment, the elastic layer made of the tape member 58 is formed on the back surface of the tray 50, but the member forming the elastic layer is not limited to this. For example, the elastic layer may be formed by coating a resin material such as an ultraviolet curable resin on the back surface of the tray. Moreover, you may make it form an elastic layer by coating urethane material on the tray back surface. Further, a rubber or elastomer sheet member may be attached.

  (Modification 2) In the above embodiment, the user sets the tray 50 at a position nipped by the conveyance roller pair 29, but the tray 50 placed on the stacker 13 is placed on the discharge drive roller 41. It may be sent to the set position shown in FIG. In this case, by providing the tape member 58 on the rear surface of the tray, the conveyance force when the tray 50 is sent from the stacker 13 to the conveyance roller pair 29 is improved, so that the tray 50 can be reliably conveyed and set. it can.

  (Modification 3) In the above embodiment, the tape member 58 is attached to the range shown in FIG. 3, but it may be attached to the entire area of the back surface of the tray. Moreover, you may make it affix a tape member on several places. For example, as shown in FIG. 7, a plurality of tape members 58 may be pasted at intervals in a direction intersecting the transport direction. In this case, since the pressure per unit area that the tape member 58 receives from the conveyance drive roller is increased, the amount of deformation of the tape member 58 is increased, and the caterpillar effect is more exerted. Therefore, the tray 50 can be conveyed more reliably.

  (Modification 4) In the above embodiment, the tray 50 on which an optical disk can be set has been described as an example. However, the medium to be transported is not limited to the tray 50, and may be thick paper such as board paper. In this case, before printing the thick paper, the sheet-like tape member is attached to the back surface of the thick paper, the thick paper with the tape member attached is set on the stacker 13 and printing is performed. The tape member may be peeled from the tape.
