Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording apparatus such as a printer, and more particularly to a recording apparatus capable of printing on a CD-R, DVD, card, or the like as a recording material.
[0002]
[Prior art]
In general, an ink jet recording apparatus performs recording by ejecting ink from a recording head to a recording medium. The recording head can be easily made compact, can record high-definition images at high speed, and has a running cost. However, since it is a low impact and non-impact method, there are advantages such as low noise, and easy recording of color images using multi-color inks, and the spread is rapidly expanding.
[0003]
In addition, the development of recording inks and recording materials has progressed, and in particular, recording on glossy paper, glossy film, and disk-like media as well as plain paper as recording materials, such as CD-Rs, DVDs, cards, etc. There is an increasing demand for printing of characters and designs on the surface of a small and thick recording material (hereinafter referred to as CD: compact disc).
[0004]
As a method for describing a title or a memo for clearly showing recorded contents on a CD, a method of attaching a label sticker to a non-recording surface is common.
[0005]
Recently, there is a print area formed so that it can be directly described with a sign pen, a felt pen, or the like.
[0006]
Here, in the case of printing a recording material in the current general-purpose printer, if the cut paper transport path is used, the rigidity of the CD is high and the size is small with respect to the cut paper. There are problems, such as being bad, and being easy to generate | occur | produce a crack.
[0007]
Therefore, an apparatus for printing contents to be described in a printing area using a personal computer is known for CDs. In particular, recently, a CD printing unit is attached as an accessory so that it can be attached to and detached from a printer body even in an inkjet printer for personal use. Some are set.
[0008]
In such an apparatus, a CD as a recording material is loaded into a holding member, the holding member is inserted into a guide portion of a support member mounted on the printer main body, set at a predetermined position, and a sheet of paper is conveyed. Printing is performed by the recording head using a path different from the path.
[0009]
In this case, when the holding member is set in the printer, first, the pressure roller pressing against the transport roller and the spur pressure against the paper discharge roller are released in conjunction with the movement of a lever provided in the printer. Thereafter, the user inserts the holding member to a predetermined position where the holding member is sandwiched between the pair of conveying rollers, and when the position is adjusted, the lever is operated again to press only the pressing roller against the holding member.
[0010]
[Problems to be solved by the invention]

[0012]
(2) When setting the holding member on the printer body, the lever is rotated to separate the pressure roller from the transport roller, and then the holding member loaded with the CD is placed on the guide portion of the support member mounted on the printer body. Insert and set in place, then rotate the lever and hold the holding member between the conveying roller and the pressure roller and carry it, so you must insert the holding member deep into the printer, It is hard to say that it is excellent in operability.
[0013]
(3) A predetermined position where the holding member is set is set to a position where the holding member is pressed against the paper discharge roller, and the pressing member acts on the paper discharge roller separately from the spur, and the paper discharge roller transports the holding member. When carrying out printing on a CD by transporting the holding member to a position that can be transported by the transport roller, applying a force in the main scanning direction to the holding member, positioning in the main scanning direction, and In addition to the force in the main scanning direction, as well as the transport force by the paper discharge roller, the transport accuracy of the holding member by the transport roller may be adversely affected.
[0014]

First, as shown in FIG. 6, when the CD transport unit 1008 is slid straight in the direction indicated by the arrow Y in the figure, it is mounted on the base 1099. At this time, as shown in FIG. 23 and FIG. 24, the fitting portions 1822 at both ends of the tray guide 1082 as the recording material holding means are inserted along the CD conveying portion guide rails 1993 provided on both sides of the base 1099. Thus, positioning is performed. On both sides of the tray guide 1082, hooks 1084 are configured to be rotatable and are urged in one direction. When the CD transport unit 1008 is slid to a predetermined position, it abuts so that it cannot slide any more. The hook 1084 acts on the stopper of the guide rail 1993 and is locked so as not to return in the sliding direction. A mechanical tray guide detection sensor 1344 for detecting a state in which the tray guide 1082 is mounted is provided on the platen. When the tray guide 1082 is mounted on the printer main body, a part of the tray guide 1082 is a tray. By pressing the guide detection sensor 1344, it is possible to detect the mounting.
[0084]
Next, as shown in FIGS. 10 and 12, when the slider 1081 is moved toward the printer main body, the arm 1085 protrudes toward the printer main body in conjunction with the slider 1081. The spur holder 1043 on which the spur 1042 is mounted is configured to be slidable up and down on the platen 1034 and is urged by a spring having a predetermined pressure. Accordingly, when the arm 1085 enters between the spur holder 1043 and the platen 1034, the spur holder 1043 is lifted upward by a predetermined amount. At this time, the arm 1085 can smoothly enter between the platen 1034 and the spur base 1043 by the inclined portion 1851 formed at the tip of the arm 1085. Thus, a space can be formed between the platen 1034 and the spur holder 1043 so that the tray 1083 as the recording material mounting means can pass therethrough. Further, the position of the arm 1085 is determined in a state where the arm 1085 is interposed between the platen 1034 and the spur holder 1043, and when the arm 1085 is stored in the tray guide 1082, the arm 1085 has a backlash with respect to the tray guide 1082. Yes.
[0085]
Further, when the slider 1081 is not initially moved toward the printer main body, the opening 1821 is closed, so that the tray 1083 cannot be inserted. When the slider 1081 is moved toward the printer main body, the slider 1081 moves obliquely upward, so that an opening 1821 appears between the slider 1081 and the tray guide 1082. In this state, the tray 1083 loaded with the CD 1882 can be inserted from the opening 1821 and set at a predetermined position. This is to prevent the tray 1083 and the spur 1042 from interfering with each other and the tray sheet 1831 at the tip of the tray 1083 and the spur 1042 from being damaged when the tray 1083 is inserted while the spur holder 1043 is not raised. It is.
[0086]
As shown in FIG. 11, when the tray 1082 pulls out the slider 1081 from the main body, the arm 1085 is detached from the spur holder 1043 in conjunction with the slider 1081, and the spur holder 1043 and the spur 1044 are lowered to predetermined positions. At this time, if the tray 1083 remains attached, the tray 1083 is sandwiched in the opening 1821 between the slider 1081 and the tray guide 1082, and the slider 1081 cannot be pulled any further. This prevents the spur 1044 from falling and damaging the CD 1882 while the CD 1882 remains in the printer body. Further, when the slider 1081 is pulled, the slider 1081 acts on the hook 1084, and the hook 1084 is detached from the guide rail 1993 of the base 1099, whereby the mounting of the CD transport unit 1008 on the printer main body is released.
[0087]
As shown in FIG. 13, the tray 1083 is formed of a resin plate having a thickness of about 2 to 3 mm, a CD mounting portion 1832, an operation portion 1833 grasped by the operator for loading and unloading the tray, a position detection mark 1834, and a CD ejection hole. 1835, an insertion position alignment mark 1836, a lateral pressure roller escape portion 1837, and a media presence / absence detection mark 1838 are provided. Further, a tray sheet 1831 is attached to the front end of the tray 1083 to ensure the bite of the tray 1083 into the transport roller 1036 and the pinch roller 1037.
[0088]
Two position detection marks 1834 are provided on the front end side of the CD mounting portion of the tray 1083, and one is provided on the opposite side. The position detection mark 1834 is provided with a member having high reflection performance in a square of about 3 to 10 mm. Here, a hot stamp is used. A concave portion 1839 is provided around the position detection mark 1834, and the reflective material can be formed along the shape of the position detection mark 1834 of the resin component. As shown in FIG. 29, since the bottom of the recess 1839 has a high surface property and is formed at a predetermined angle, the light emitted from the tray position detection sensor 1059 provided on the carriage 1050 is emitted from other than the position detection mark 1834. Even if it is reflected by the light, it does not return to the light receiving portion, thus preventing erroneous detection. As described above, since the reflectance of the position detection mark 1834 on the tray 1083 is high, it is not necessary to mount a high-performance sensor and processing such as correction can be reduced, thereby avoiding an increase in cost and an increase in printing time. Can do. Further, compared with a method of directly reading the edge of the CD printing area, detection can be accurately performed even when reprinting a colored CD, once printed.
[0089]
The CD attachment portion 1832 is provided with a plurality of mold claws, and performs positioning and backlash removal when the CD 1882 is attached. The operator attaches the center hole of the CD 1882 with the CD attachment portion 1832. At the time of removal, the CD removal hole 1835 at two locations is used so that the operator can remove the CD 1882 by holding the outer peripheral edge. Further, the CD mounting portion is one step lower than the other surface of the tray 1083. On the lower surface, a medium presence / absence detection mark 1838 is provided. This is configured such that a hole having a predetermined width is provided in a hot stamp having a predetermined width, and it is determined that there is no medium when the hole width is detected.
[0090]
A tray sheet 1831 is attached to the front end of the tray 1083 to ensure the bite of the tray 1083 into the transport roller 1036 and the pinch roller 1037. The tray sheet 1831 is made of a sheet material made of PET or the like having a thickness of about 0.1 to 0.3 mm, and has a predetermined coefficient of friction and hardness. In addition, the tray 1083 itself has a tapered portion 1830 at the tip. First, the tray sheet 1083 is bitten by the transport roller 1036 and the pinch roller 1037, thereby generating a transport force. The pinch roller 1037 lifts the tapered portion 1830 at the tip of the tray 1083, so that the thick tray 1083 is transported. 1036 and the pinch roller 1037, and the tray 1083 can be conveyed. The position detection mark 1834 is provided between the pinch rollers 1037. Therefore, the position detection mark 1834 is prevented from coming into contact with the pinch roller 1037 and scratching the surface.
[0091]
Further, as shown in FIGS. 20, 25, and 26, a supported portion 1861 supported by a tray support portion 1862 provided on a tray guide 1082 to be described later and the tray 1082 are conveyed to the back surface of the tray 1083. In this case, a groove 1860 for preventing the tray support surface 1862a of the tray support 1862 from coming into contact with the back surface of the tray 1083 is provided.
[0092]
At this time, in addition to the tray support portion 1862, another tray support portion 1863 is provided on the downstream side in the discharge direction of the tray support portion 1862 on the tray guide 1082, but the tray support surface 1863a of the other tray support portion 1863 is provided. This height is lower than the height of the tray support surface 1862a, so that entry of the tray 1083, which will be described later, in the direction in which the front end portion faces obliquely upward to the left in FIG.
[0093]
Further, by supporting the tray 1082 by the tray support portion 1863, the sliding surface with the tray 1082 is limited, and the sliding resistance is reduced, thereby contributing to the improvement of the transportability.
[0094]
Further, a rib 1870 formed by providing a recess 1871 on the transported surface 1872 of the tray 1083 is provided so as to contact the transport unit 1401 of the first paper discharge roller 1040 and the transport unit 1411 of the second paper discharge roller 1041. It has been.
[0095]
Further, as shown in FIGS. 7, 19, 27, and 28, the tray guide 1082 includes a lateral pressure roller 1824 that is an urging means for pressing the tray 1083 against the reference 1823 of the tray guide 1082. The tray 1083 is pressed against the reference 1823 with a predetermined pressure by the side pressure roller spring 1825 to position the tray in the main scanning direction.
[0096]
At this time, the side pressure roller 1824 acts on the tray at least until the operator sets the tray 1083 at a predetermined position (FIGS. 22, 26, and 27), and the tray 1083 is conveyed by the conveying roller 1036 and the pinch roller 1037. When this is done (FIGS. 24 and 28), the side pressure roller escape portion 1837 comes to the position where the side pressure roller 1824 acts, so the side pressure roller 1824 does not act on the tray 1083, and extra back tension acts on the tray 1083. Therefore, the conveyance accuracy of the tray 1083 is prevented from decreasing.
[0097]
At this time, the notch start position 1837a of the side pressure roller escape portion 1837 is formed as a slope in order to gradually release the urging force to the tray 1083 and suppress fluctuations in the force.
[0098]
The slider 1081 is provided with a pressing roller 1811 as pressing means on the left and right sides in the vicinity of the second paper discharge roller 1041 via a pressure roller holder 1881, and the roller 1018 holds the tray 1083 at a predetermined pressure by the roller spring 1812. The conveyance force of the tray 1083 is generated by pressing against the 1041 and the first paper discharge roller 1040. With this conveying force, the tray 1083 can be conveyed from the set position (FIGS. 22 and 27) to the nip portion of the conveying roller 1036 and the pinch roller 1037 at the start of printing.
[0099]
Further, when printing is finished, the tray 1083 can be transported to a predetermined position where the operator takes it out. Also in this case, the position of the position detection mark 1834 and the position of the pressing roller 1811 are different. Therefore, the position detection mark 1834 is prevented from coming into contact with the pressing roller 1811 and scratching the surface.
[0100]
The tray 1083 can be taken out from the tray guide 1082 by pulling out the tray 1083 conveyed to a predetermined position. Further, the operator can remove the CD 1882 by holding the outer peripheral edge of the CD 1882 by using the two CD ejection holes 1835.
[0101]
Next, the printing operation on the CD 1882 when the above configuration is used will be described.
[0102]
When the CD transport unit 1008 is slid straight toward the main body, it is mounted on the base 10099. At this time, the tray guide detection sensor 1344 can detect that the tray guide 1082 is attached to the printer body.
[0103]
Further, when the slider 1081 is moved in the direction of the printer main body, the arm 1085 projects in the direction of the printer main body in conjunction with the slider 1081. Then, when the arm 1085 enters between the spur holder 1043 and the platen 1034, the spur holder 1043 is lifted upward by a predetermined amount.
[0104]
As described above, when the slider 1081 is moved in the direction of the printer body, the slider 1081 moves obliquely upward, so that an opening 1821 appears between the tray guide 1082 and the tray 1083 loaded with the CD1882 is removed. It can be inserted through the opening 1821 and set at a predetermined position.
[0105]
In this state, the operator holds the operation portion 1833 of the tray 1083 loaded with the CD 1882 in the CD attachment portion 1832 of the tray 1083, and inserts the tray 1083 from the opening 1821 as shown in FIG. The tray 1083 loaded with the CD 1882 is set at a predetermined position where the alignment mark 1836 matches the tray set mark 1826 of the tray guide 1082.
[0106]
At this time, the state description from the tray set to the process of transporting the tray 1083 will be described with reference to FIGS. 21 to 28 and FIG. 17.
[0107]
FIG. 21 is a diagram showing a state in which the setting of the tray 83 is started. In this state, the supported portion 1861 of the tray 1083 is supported by the tray supporting surface 1862a of the tray supporting portion 1862 on the tray guide 1082. Therefore, the tray 1083 enters in the direction in which the front end portion is directed diagonally upward to the left in FIG. 21. As a result, the tray sheet 1831 attached to the front end portion of the tray 1083 is discharged from the discharge roller. Thus, the tray 1083 can enter the recording apparatus without a sense of resistance.
[0108]
At this time, as shown in FIG. 25, the insertion of the tray 1083 causes the rib 1870 of the tray 1083 to rub against the transport unit 1401 of the first paper discharge roller 1040 and the transport unit 1411 of the second paper discharge roller 1041. Because of the rubbing against the ribs 1870, the frictional resistance with the surfaces of the conveying units 1401 and 1411 is low, and the generation of the rubbing sound generated by the deformation of the surfaces of the conveying units 1401 and 1411 due to rubbing is suppressed. Will be.
[0109]
Next, FIGS. 22, 26, and 27 are views showing a state in which the tray 1083 is further moved into the recording apparatus from the states of FIGS. 21 and 25, and this state is the set position of the tray 1083. Become. That is, the operator has inserted the tray 1083 until the tray insertion position alignment mark 1836 and the tray set mark 1826 of the tray guide 1082 coincide with each other.
[0110]
In this state, the groove 1860 of the tray 1083 is positioned to face the tray support surface 1862a of the tray support portion 1862 on the tray guide 1082, and the tray 1083 is diagonally left upward in FIG. 22 by the tray support surface 1862a. Further, the support in the direction in which the front end of the tray 1083 faces is released. Then, the conveying portion 1411 of the second paper discharge roller 1041 is pressed against the conveying surface 1872 of the tray 1083 by a pressing roller 1811 by the roller spring 1812 with a sufficient contact area and a predetermined pressure, and the rib 1870 of the tray 1083 is The conveyance unit 1401 of the one paper discharge roller 1040 is pressed with a predetermined pressure, and the conveyance force is applied to the tray 1083.
[0111]
FIG. 23, FIG. 24, and FIG. 28 are diagrams showing a state in which a print signal is sent from the host and the print operation is started in the states of FIG. 22, FIG. 26, and FIG.
[0112]
First, in the state shown in FIGS. 22, 26, and 27, the transport roller 1036, the first paper discharge roller 1040, and the second paper discharge roller 1041 rotate in the direction of arrow A in FIG. 22 (hereinafter referred to as reverse rotation). . At this time, the conveying portion 1411 of the second paper discharge roller 1041 is pressed against the surface to be conveyed 1872 of the tray 1083 by a pressing roller 10811 by a roller spring 1812 with a sufficient contact area and a predetermined pressure, and the rib 1870 of the tray 1083 is Since the conveyance unit 1401 of the first paper discharge roller 1040 is pressed with a predetermined pressure, a conveyance force is generated on the tray 1083, so that the first paper discharge roller 1040 and the second paper discharge roller 1041 are rotated according to the reverse rotation. The tray 1083 is conveyed into the printer. Then, when the tray sheet 1083 is bitten by the transport roller 1036 and the pinch roller 1037, a predetermined transport force is generated, the pinch roller 1037 is lifted up the tapered portion 1830 at the tip of the tray 1083, and the tray 1083 is transported by the transport roller 1036 and the pinch. It is sandwiched between rollers 1037. (FIGS. 24 and 28)
As shown in FIGS. 24 and 28, when the tray 1083 is conveyed by the conveying roller 1036 and the pinch roller 1037, the side pressure roller escape portion 1837 comes to a position where the side pressure roller 1824 of the tray 1083 acts. Therefore, the lateral pressure roller 1824 does not act on the tray 1083, and excess back tension or the like does not act on the tray 1083, so that the tray 1083 is transported without lowering the transport accuracy.
[0113]
Next, the carriage 1050 moves from the home position to the print area in order to detect the tray 1083. At this time, as shown in FIG. 18, the carriage lifting / lowering motor 1059 is driven, the guide shaft 1052 is raised, and an optimum gap can be formed with respect to the tray 1083.
[0114]
As shown in FIGS. 15A and 15B, the carriage 1050 stops the tray position detection sensor 1059 in accordance with the position of the position detection mark 1834a of the tray 1083. Then, the tray 1083 is conveyed and the edge position of the upper end of the position detection mark 1834a is detected. The conveyance is continued as it is, and the lower edge of the mark 1834a is detected. Next, the tray 1083 is returned so that the tray position detection sensor 1059 is positioned approximately at the center of the position detection mark 1834a in FIG. Then, the carriage 1050 is moved left and right to detect the right end edge position and the left end edge position of the position detection mark 1834a. From the above, the center position 1834ac of the position detection mark 1834a can be calculated, and the printing position of the CD 1882 mounted on the tray 1083 is obtained from the center position 1834ac. As described above, since the position of the tray itself is detected, printing does not shift due to variations in component accuracy, the state of the tray, and the like, compared to a case where printing is performed only with mechanical accuracy without detection.
[0115]
After detecting the position of the position detection mark 1834a, the carriage 1050 moves to detect the position detection mark 1834b as shown in FIG. By detecting the edges at both ends, it is confirmed that the position detection mark 1834a detected earlier is correct. This is because when the tray 1083 is inserted deeper than the regular set position, the position detection mark 1834b is moved to detection even if the position detection mark 1834c position is detected, as shown in FIG. The position detection mark 1834a can be detected.
[0116]
After the tray 1083 position is detected, as shown in FIG. 15F, the tray 1083 is arranged so that the tray position detection sensor 1059 position of the carriage 1050 and the medium presence / absence detection mark 1838 position of the tray 1083 coincide with each other in the tray 1083 conveyance direction. Transport. At this time, the detection hole edge of the medium presence / absence detection mark 1838 is detected, and if it matches the predetermined hole width, it is determined that the CD 1882 is not installed, the printing operation is interrupted, the tray 1083 is ejected to a predetermined position, and an error occurs. Is displayed. If the media presence / absence detection mark 1838 cannot be detected, it is determined that the CD 1882 is mounted, and the printing operation is continued.
[0117]
When the above series of initial operations is completed, the tray 1083 is conveyed to a predetermined position where the entire CD 1882 in the back of the printer can be printed. Thereafter, printing is started in accordance with image data sent from the host. By using so-called multi-pass printing in which an image is formed by a plurality of scans, band unevenness due to conveyance accuracy and landing accuracy of the head 1007 can be reduced.
[0118]
After the printing is completed, the tray 1083 conveys the tray 1083 to a position where the operator sets the tray 1083 on the tray guide 1082 before the above-described printing. In this state, the operator can take out the tray 1083 on which the printed CD 1882 is mounted. Further, by pulling the slider 1081, the arm 1085 is released from the spur holder 1043, and the hook 1084 is released from the base 1099, whereby the CD transport unit 1008 is released from the printer main body and can be removed.
[0119]
With the above configuration and operation, when the tray is set on the tray guide with a low-cost and space-saving configuration, positioning of the tray with respect to the printer in the main scanning direction can be reliably performed with high accuracy.
[0120]
Further, after the tray is set, the tray can be transported stably with high accuracy.
[0121]
(Second Embodiment)
In the first embodiment, when the tray 1083 is transported by the transport roller 1036 and the pinch roller 1037, the side pressure roller escape portion 1837 comes to a position where the side pressure roller 1824 of the tray 1083 acts. In the above description, the excessive back tension or the like does not act on the tray 1083. However, as shown in FIGS. 29 and 30, the tray 1183 ′ includes a pressing roller escape portion 1890 formed by a groove, and the tray 1083 ′ In the state of being conveyed by the conveying roller 1036 and the pinch roller 1037 (FIG. 30), the pressing roller escape portion 1890 comes to a position where the pressing roller 1811 of the tray 1083 ′ acts, and extra back tension or the like is applied to the tray. The tray 1083 ′ is configured not to act on the 1083 ′, and the tray 1083 ′ In the state before being transported by the roller 1037 (FIG. 29), the pressing roller 1811 acts on the tray 1083 ′ to apply a transporting force to the tray 1083 ′. With the same configuration and description, the same effect as described above can be obtained.
[0122]
At this time, the same effect as described above can be obtained even if the inclined portion 1890a is provided at both ends of the pressing roller escape portion 1890 so that the tray 1083 'can be smoothly moved.
[0123]
(Third embodiment)
In the first embodiment, when the tray 1083 is conveyed by the conveying roller 1036 and the pinch roller 1037, the side pressure roller 1824 does not act on the tray 1083, and the second embodiment. In the above description, the side pressure roller 1824 and the pressing roller 1811 do not act on the tray 1083 ′ when the tray 1083 ′ is conveyed by the conveying roller 1036 and the pinch roller 1037. However, the tray 1083 or the tray 1083 is not described. In the state where the side pressure roller 1824 or the position where the side pressure roller 1824 and the pressure roller 1811 do not act is required, high-precision conveyance is required while the tray 1083 or the tray 1083 ′ is conveyed by the conveyance roller 1036 and the pinch roller 1037. Even if it is configured to be in a certain section, Explanation the same configuration, it is possible to obtain the same effect as described above.
[0124]
(Fourth embodiment)
In the embodiments described above, the members acting on the tray 1083 or the tray 1083 ′ have been described as the side pressure roller 1824 that obtains the urging force from the side pressure roller spring 1825 and the pressing roller 1811 that obtains the urging force from the roller spring 1812. Even if the side pressure roller 1824 and the pressing roller 1811 are elastic portions provided on the leaf spring or the tray guide 1082, the same effects as described above can be obtained by the same configuration and description as described above.
[0125]
(Fifth embodiment)
In the above-described embodiments, the side pressure roller escape portion 1837 in which the tray 1083 or the tray 1083 ′ is notched is configured to prevent the side pressure roller 1824 and the pressing roller 1811 from acting on the tray 1083 or the tray 1083 ′. However, even if the notch is a concave surface and the groove is a hole, the same effect as described above can be obtained by the same configuration and description as described above. .
[0126]
(Sixth embodiment)
In the embodiments described above, the spurs 1042 are provided at positions corresponding to the transport unit 1401 of the first paper discharge roller 1040 and the transport unit 1411 of the second paper discharge roller 1041, respectively. When the recording medium such as paper is continuously conveyed, paper dust adheres to the conveyance units 1401 and 1411, and the conveyance force of the first paper discharge roller 1040 and the second paper discharge roller 1041 may decrease.
[0127]
Therefore, in order to prevent instability of conveyance of the tray 1083 or the tray 1083 ′ due to a decrease in conveyance force, a spur 1042 is previously set at a position corresponding to the conveyance unit 1411a of the second discharge roller 1041 ′ shown in FIG. It is configured not to be arranged, and includes a transport unit 1411a in a state where the urging of the sheet by the spur 1042 is weak with respect to the transport unit 1411a, and a transport unit 1411a in a state in which the transport force is difficult to decrease.
[0128]
In this state, the pressing roller 1811 is brought into pressure contact with the tray 1083 or the tray 1083 ′ at a predetermined pressure, so that the tray 1083 or the tray 1083 ′ is brought into contact with the conveying units 1411 and 1411a of the second paper discharge roller 1041 ′. By pressing the roller 1040 against the conveyance unit 1401, it is possible to apply a stable conveyance force to the tray 1083 or the tray 1083 ′, and the other effects are the same as described above with the same configuration and description as before. Can be obtained.
[0129]
At this time, the transport unit 1411a that does not have the spur 1042 in the corresponding position is more effective when it is configured to be provided with respect to the transport unit in the vicinity of the pressing roller 1811.
[0130]
Further, in the above-described embodiment, the transport unit 1411a that does not have the spur 1042 at the corresponding position is two places shown in FIG. 31, but this is not limited to two places. Of course, it is set as the structure of only one place of the one side mentioned above. Alternatively, the same effect as described above can be obtained by the same description up to the above even with three or more configurations.
[0131]
In addition, even if the paper discharge roller 1040 is provided with the conveyance unit 1401 that does not have the spur 1042 at the corresponding position, the same effect as described above can be obtained.
