[0048]
Next, the CD transport unit 8 according to the present invention and CD printing using the CD transport unit 8 will be described in detail with reference to FIGS.
[0049]
FIG. 6 is a perspective view of the CD transport unit 8 attached to the printer main body, FIG. 7 is a perspective view of the CD transport unit 8, FIG. 8 is a configuration diagram of the CD transport unit attachment and attachment detection unit of the base 99, and FIG. FIG. 10 is a perspective view of the CD transport unit 8 when the slider 81 is moved, and FIG. 11 is a perspective view of the base 99 and the release of the hook 104 of the CD transport unit 8. FIG. 12 is an explanatory view of the configuration of the arm 85 when the slider 81 is moved, FIG. 13 is a plan view of the tray 83, FIG. 14 is an explanatory view of the concave shape of the position detection portion of the tray, and FIG. FIG. 16 is a perspective view of a relative position of the position detection sensor, FIG. 16 is a perspective view in which a tray is set in a CD transport section, FIG. 17 is an explanatory view of a tray being transported, FIG. Lateral pressure roller, It is an operation diagram for the pressure roller tray.
[0050]
As shown in FIG. 6, when the CD transport section 8 is slid straight in the direction of arrow Y shown in FIG. At this time, as shown in FIGS. 8 and 9, positioning is performed by inserting the fitting portions 822 at both ends of the tray guide 82 along guide rails 993 provided on both sides of the base 99. On both sides of the tray guide 82, hooks 104 are configured to be rotatable and urged in one direction. When the CD transport unit 8 is slid to a predetermined position, the CD transport unit 8 comes into contact so that it cannot slide any more. Then, the hook 104 acts on the stopper of the guide rail 993 and is locked so as not to return to the sliding direction. A mechanical tray guide detection sensor 344 for detecting a state in which the tray guide 82 is mounted is provided on the platen. When the tray guide 82 is mounted on the printer body, a part of the tray guide 82 becomes a tray. By pressing the guide detection sensor 344, the mounting can be detected.
[0051]
Next, as shown in FIGS. 10 and 12, when the slider 81 is moved toward the printer main body, the arm 85 is protruded toward the printer main body in conjunction with the slider 81. The spur base 43 on which the spur 42 is mounted is configured to be slidable up and down on the platen 34, and is urged to the platen by a spring of a predetermined pressure. Therefore, when the arm 85 enters between the spur base 43 and the platen 34, the spur base 43 is lifted upward by a predetermined amount. Thereby, the spur 42 is separated from the paper discharge rollers 40 and 41. At this time, the arm 105 can smoothly enter between the platen 34 and the spur base 43 by the inclined portion 851 formed at the tip of the arm 85.
[0052]
Further, an inclined portion is also provided in an insertion portion of the spur base 43 and the platen 34.
[0053]
Thereby, a space through which the tray 83 can pass can be formed between the platen 34 and the spur base 43. The position of the arm 85 is determined when the arm 85 is inserted between the platen 34 and the spur base 43. When the arm 85 is stored in the tray guide 82, the arm 85 has a play with respect to the tray guide 82. I have.
[0054]
Therefore, even if there is a mounting error between the tray guide 82 and the base 99, since the arm 85 follows the platen and the spur base 43, the amount of rise of the spur base 43 can be accurately set only by the thickness of the arm 85. Therefore, the amount of elevation of the spur base 43 is too small to secure a sufficient CD-R paper path, and the amount of elevation is too large to interfere with other components such as the carriage.
[0055]
In the above configuration, when the slider 81 is not moved in the direction of the printer main body, the opening 821 is closed, so that the tray 83 cannot be inserted. When the slider 81 is moved in the direction of the printer main body, the opening is formed between the slider 81 and the tray guide 82 because the slider 81 moves obliquely upward. In this state, the tray 83 loaded with the CD can be inserted through the opening 821 and set at a predetermined position. This prevents the tray 83 and the spur 42 from interfering with each other and the tray sheet 831 and the spur 42 at the tip of the tray 83 from being damaged when the tray 83 is inserted with the spur base 43 not raised. That's why.
[0056]
As shown in FIG. 11, when the tray 82 pulls out the slider 81 from the main body, the arm 85 is disengaged from the spur base 43 in conjunction with the slider 81, and the spur base 43 and the spur 44 are lowered to predetermined positions. At this time, if the tray 83 is still mounted, the tray 83 is caught in the opening 821 between the slider 81 and the tray guide 82, and the slider 81 cannot be pulled further. This prevents the spur 44 from lowering and damaging the CD while the CD remains in the printer body. Further, when the slider 81 is pulled, the slider 81 acts on the hook 104 and the hook 104 comes off the guide rail 993 of the base 99, whereby the mounting of the CD transport unit 8 on the printer body is released.
[0057]
As shown in FIG. 13, the tray 83 is a resin plate having a thickness of about 2 to 3 mm as shown in FIG. An alignment mark 836, a side pressure roller escape portion 387, and a medium presence / absence detection mark 838 are provided. Further, a tray sheet 831 is attached to the leading end of the tray 83 for ensuring that the tray 83 bites into the transport roller 36 and the pinch roller 37.
[0058]
Two position detection marks 834 are provided on the tip side of the CD mounting portion of the tray 83 and one on the opposite side. The position detection mark 834 is provided with a member having a high reflection performance in a square of about 3 to 10 mm. Here, it is formed using a hot stamp. A concave portion 839 is provided around the position detection mark 834, and a reflective material can be formed in a shape along the shape of the position detection mark portion of the resin component. Further, as shown in FIG. 14, since the bottom of the concave portion 839 is formed with a high surface property and at a predetermined angle, the light emission of the tray position detecting sensor 59 provided on the carriage 50 is different from the position detecting mark 834. Even if the light is reflected by the light source, it does not return to the light receiving portion, thereby preventing erroneous detection. As described above, since the reflectance of the position detection mark 834 on the tray 83 is high, it is not necessary to mount a high-performance sensor, and processing such as correction can be reduced, so that cost increase and increase in printing time can be avoided. Can be. Further, as compared with the method of directly reading the edge of the print area of the CD, the detection can be performed accurately even when reprinting on a colored CD or once recorded.
[0059]
The CD mounting portion 832 is provided with a plurality of mold claws, and performs positioning and play when a CD is mounted. The operator mounts the CD by aligning the hole at the center of the CD with the CD mounting portion 832. At the time of removal, the two CD removal holes 835 are used so that the operator can remove the CD by holding the outer peripheral edge of the CD. The CD mounting portion is one step lower than the surface of the other tray 83. A medium presence / absence detection mark 838 is provided on the lower surface. In this configuration, a hole having a predetermined width is provided in a hot stamp having a predetermined width, and when the hole width is detected, it is determined that there is no medium.
[0060]
At the leading end of the tray 83, a tray sheet 831 for ensuring that the tray 83 bites into the transport roller 36 and the pinch roller 37 is attached. The tray sheet 831 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. Also, the tray 83 itself has a tapered portion 830 at the tip. First, the tray sheet 83 is bitten by the transport roller 36 and the pinch roller 37 to generate a transport force, and the pinch roller 37 lifts the tapered portion 830 at the tip of the tray 83, thereby transporting the thick tray 83 to the transport roller. 36, can be pinched by the pinch rollers 37, and the tray 83 can be transported. The position detection mark 834 is provided between the pinch rollers 37. Therefore, the position detection mark 834 is in contact with the pinch roller 37 to avoid scratching the surface.
[0061]
As shown in FIG. 19, a side pressure roller 824 for pressing the tray 83 against the reference 82 of the tray guide 82 is provided on the tray guide 82, and is pressed against the tray 83 reference 82 with a predetermined pressure by a roller spring 825. Positioning is being performed. The side pressure roller 824 operates until the operator sets the tray 83 at a predetermined position. When the tray 83 is conveyed by the conveying roller 36 and the pinch roller 37, the side pressure roller 824 escapes to a position where the side pressure roller 824 operates. Since the portion 387 comes, the side pressure roller 824 does not act on the tray 83, so that unnecessary back tension does not act on the tray 83, thereby preventing a decrease in the transport accuracy of the tray 83.
[0062]
The slider 81 is provided with pressing rollers 811 on the left and right sides, and the conveying force of the tray 83 is generated by pressing the tray 83 against the paper discharge roller 241 with a predetermined pressure by a roller spring 812. With this transport force, the tray 83 can be transported from the set position to the nip portion between the transport roller 36 and the pinch roller 37 at the start of printing. Further, when printing is completed, the tray 83 can be transported to a predetermined position where the operator takes it out. Also in this case, the position of the position detection mark 834 and the pressing roller 811 are configured differently. Therefore, the position detection mark 834 is prevented from contacting the pressing roller 811 and damaging the surface.
[0063]
Then, by pulling out the tray 83 conveyed to a predetermined position, the tray 83 can be taken out from the tray guide 82. Furthermore, the operator can remove the CD by holding the outer peripheral edge of the CD by using the two CD removal holes 835.
[0064]
Next, an operation of printing on a CD when the above configuration is used will be described.
[0065]
When the CD transport section 8 is slid straight toward the main body, it is mounted on the base 99. At this time, the tray guide detection sensor 344 can detect that the tray guide 82 is attached to the printer main body.
[0066]
Further, when the slider 81 is moved in the direction of the printer main body, the arm 85 projects in the direction of the printer main body in conjunction with the slider 81. When the arm 85 enters between the spur base 43 and the platen 34, the spur base 43 is lifted upward by a predetermined amount.
[0067]
As described above, when the slider 81 is moved in the direction of the printer main body, the slider 81 moves diagonally upward, so that an opening 821 appears between the slider 81 and the tray guide 82. In this state, as shown in FIG. 16, the tray 83 loaded with the CD can be inserted through the opening 821 and set at a predetermined position.
[0068]
Then, the CD is mounted on the CD mounting portion 832 of the tray 83. The operator holds the operation unit 833 and inserts the tray 83 until the position detection mark 834 matches the tray set mark 826 of the tray guide 82.
[0069]
In this state, when a recording signal is sent from the host, the recording operation is started. First, as shown in FIG. 17, the transport roller 36, the paper discharge roller 140, and the paper discharge roller 241 rotate in reverse. By pressing the tray 83 against the paper discharge roller 140 and the paper discharge roller 241 with a predetermined pressure by the pressing roller 811, and the roller spring 812, the conveyance force of the tray 83 is generated, so that the paper discharge roller 140 and the paper discharge roller 241 rotate in reverse. , The tray 83 is conveyed into the printer. When the tray sheet 83 is bitten by the transport roller 36 and the pinch roller 37, a predetermined transport force is generated, the pinch roller 37 lifts the tapered portion 830 at the tip of the tray 83, and the tray 83 is moved by the transport roller 36 and the pinch roller 37. Is sandwiched between.
[0070]
Next, the carriage 50 moves from the home position to the recording area in order to detect the tray 83. At this time, as shown in FIG. 18, the carriage elevating motor 59 is driven to elevate the guide shaft 52, so that an optimum gap can be formed for the tray 83.
[0071]
As shown in FIGS. 15A and 15B, the carriage 50 stops the tray position detection sensor 59 in accordance with the position of the position detection mark 834a of the tray 83. Then, the tray 83 is transported, and the edge position at the upper end of the position detection mark 834a is detected. The conveyance is continued as it is, and the lower edge of the mark 834a is detected. Next, as shown in FIG. 15C, the tray 83 is returned so that the tray position detection sensor 59 is substantially at the center of the position detection mark 834a. Then, the carriage 50 is moved right and left to detect the right edge position and the left edge position of the position detection mark 834a. From the above, the center position 834ac of the position detection mark 834a can be calculated, and the print position of the CD mounted on the tray 83 is obtained from the center position 834ac. 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, as compared with the case where printing is performed only with mechanical accuracy without performing detection.
[0072]
After detecting the position of the position detection mark 834a, the carriage 50 moves to detect the position detection mark 834b as shown in FIG. By detecting the edges at both ends, it is confirmed that the position detection mark 834a detected earlier is correct. This is because, when the tray 83 is inserted deeper than the regular set position, even if the position of the position detection mark 834c is detected as shown in FIG. , It is possible to detect that it is not the position detection mark 834a.
[0073]
After the position of the tray 83 is detected, as shown in FIG. 15F, the tray 83 is moved so that the position of the tray position detection sensor 59 of the carriage 50 and the position of the medium presence / absence detection mark 838 of the tray 83 coincide in the tray 83 conveyance direction. Is transported. At this time, the detection hole edge of the medium presence / absence detection mark 838 is detected, and if it matches the predetermined hole width, it is determined that the CD is not mounted, the printing operation is interrupted, the tray 83 is ejected to the predetermined position, and an error occurs. Is displayed. If the medium presence / absence detection mark 838 cannot be detected, it is determined that a CD is mounted, and the printing operation is continued.
[0074]
When the above series of initial operations is completed, the tray 83 is transported to a predetermined position at the back of the printer where the entire CD can be recorded. After that, recording is started according to the image data sent from the host. By using so-called multi-pass printing in which an image is formed by a plurality of scans, it is possible to reduce band unevenness and the like due to transport accuracy and landing accuracy of the head 7.
[0075]
After the printing is completed, the tray 83 conveys the tray 83 to a position where the operator sets the tray 83 on the tray guide 82 before the above-described printing. In this state, the operator can take out the tray 83 on which the printed CD is mounted. Further, by pulling the slider 81, the arm 85 is released from the spur base 43, and the hook 104 is released from the base 99, whereby the CD transport unit 8 is released from the main body printer and can be removed.
[0076]
Here, the relationship between the shape of the spur base 43 and the carriage 50 will be described in detail with reference to FIGS.
[0077]
20 is a front view of the relationship between the spur base and the carriage in the normal position, FIG. 21 is a front view of the relationship between the spur base in the raised position, and the carriage in the normal position, and FIG. FIG. 23 is a top view of the spur base and the platen periphery. In the present specification, the expression that the spur base 43 is at the normal position means that the ink tank replacement-recovery area 43A (described later) of the spur base 43 is Ref. 20 (see FIG. 20), and that the carriage 50 is in the normal position means that the lower surface of the carriage 50 facing the spur base 43 is ref. (See FIG. 20). Further, that the spur base 43 is at the raised position means that the ink tank exchange-recovery area 43A of the spur base 43 is in the Ref. From height h ₁ 22 (see FIG. 22), and that the carriage 50 is at the raised position means that the lower surface of the carriage 50 facing the spur base 43 is ref. From height h ₂ (See FIG. 22).
[0078]
An ink sensor 103 for detecting the remaining amount of ink in an ink tank 71 mounted on the carriage 50 is attached to the spur base 43. The ink sensor 103 needs to be disposed relatively close to the ink tank 103 in order to detect the amount of reflection from the ink in the ink tank 103. The spur base 43 includes an ink sensor holding section 43C that holds the ink sensor 103, and an ink tank replacement / recovery area 43A that is 3 mm lower than the ink sensor holding section 43C. The ink sensor holding portion 43C and the ink tank exchange-recovery region 43A are smoothly connected by the tapered portions 43B and 43D.
[0079]
20 to 22 schematically show each position of the carriage 50 in the main scanning direction. The home position (cap position) 50A is a position where the recording head 7 is capped by the cap 61 of the cleaning unit 6 and sucked. The recovery position 50B is a position where the carriage 50 temporarily retreats when the cleaning unit 6 opens to the atmosphere after suction or after wiping by the blade 62. The ink tank replacement position 50C is a position where the ink tank 71 is replaced, and the ink sensor detection position 50D is a position where the ink sensor 103 detects the remaining amount of ink.
[0080]
The clearance between the lower surface of the carriage 50 and the surface of the ink tank replacement-recovery area 43A and the ink sensor holding portion 43C of the spur base 43 is such that when the spur base 43 and the carriage 50 shown in FIG. -C in the recovery area 43A ₂ = 6.5 mm, C at ink sensor holding part 43C ₁ = 3.5 mm.
[0081]
As shown in FIG. 21, when the position height of the carriage 50 does not rise at the normal position and only the spur base 43 rises from the normal position indicated by the broken line to the rising position, the rising amount of the spur base 43 becomes h. ₁ = 4.5 mm, the clearance between the carriage 50 and the spur base 43 in the ink tank replacement-recovery area 43A is C ₂ = 2 mm, but C for the ink sensor holding portion 43C. ₁ = -1 mm, that is, 1 mm interference.
[0082]
Also, as shown in FIG. 22, when both the spur base and the carriage 50 have risen from the normal position shown by the broken line to the rise position, both h ₁ = H ₂ = 4.5 mm, the relative height relationship between them is the same as in FIG. ₂ = 6.5 mm, C at ink sensor holding part 43C ₁ = 3.5 mm.
[0083]
Here, when the user exchanges ink, the carriage 50 moves to an ink tank exchange position 50C where the ink tank can be exchanged. In the present embodiment, the spur base 43 includes the Ref. Or from the normal position shown in FIG. 21 and FIG. ₁ = 4.5 mm, the clearance is maintained between the carriage 50 and the spur base 43, so that the spur base 43 is positioned at either the normal position or the raised position. Since the carriage 50 can be moved to the ink tank replacement position 50C without worrying about whether or not the operation is performed, the usability is good. For example, when the carriage 50 and the spur base 43 are at the normal position, the tray guide 82 is set during ink replacement, so that even if the arm 85 raises only the spur base 43, the 43A portion of the spur base 43 is Since the shape of the carriage 50 escapes, no problem such as interference occurs (the carriage 50 rises when the tray guide detection sensor 344 detects the tray guide 82, but there is a time lag until the lifting is completed).
[0084]
Similarly, the carriage 50 is movable at the recovery position 50B regardless of the position of the spur base 43, and the same effect is obtained.
[0085]
On the other hand, if the ink sensor holding unit 43C is lowered to avoid interference, the reflection of the ink in the ink tank 71 cannot be sufficiently detected, so that the ink sensor holding unit 43C cannot be changed from the current position. The carriage 50 and the spur base 43 are both at the normal position when printing cut sheets, and the carriage 50 and the spur base 43 are both at the elevated position when printing thick paper such as a CD-R. Therefore, the clearance between the ink sensor holding unit 43C and the carriage 50 is increased. Is C ₁ = 2 mm. However, even in the event that the carriage 50 runs out of control due to a failure or the like, in the present embodiment, the tapers 43B and 43C are formed between the ink tank replacement / recovery area 43A and the surface of the ink sensor holding section 43C. , To prevent damage to the main body. That is, even when the carriage 50 runs away in the positional relationship shown in FIG. 21 in which the carriage 50 and the ink sensor holding portion 43C interfere with each other, the play of the carriage 50 and the spur base 43 are bent, so that the tapers 43B and 43C are smoothly formed. Since the carriage 50 runs over, no impact force is applied to the carriage 50 and the main body, so that the main body is not damaged.
[0086]
If the carriage 50 always moves up and moves as shown in FIG. 22, the chance of interference with the carriage 50 decreases even if the ink tank replacement-recovery area 43A of the spur base 43 is not low, but the carriage 50 rises every time. In order to achieve this, the guide shaft 52 is raised, so that it takes time and there are disadvantages in terms of durability of the lifting mechanism. Further, since the cleaning unit 6 is not configured to rise, the carriage 50 needs to be moved to a normal position in order for the cleaning unit 6 to suck and recover the recording head 7 on the carriage 50. It is disadvantageous in that it takes time and the durability of the lifting mechanism.
[0087]
Further, the carriage 50 may be largely separated from the spur base 43 in the normal position so that the ink sensor holding portion 43C does not interfere with the carriage 50 even if the spur base 43 is raised. Since the mounted recording head 7 is largely separated from the recording surface of the sheet material P, there is a disadvantage that image quality is deteriorated.
[0088]
Since the carriage 50 is not unnecessarily separated from the platen 34 by the shape of the spur base 43 as described above, it is possible to provide a recording apparatus that can perform CD-R printing, has high recording quality, has high reliability, and is easy to use. be able to.
[0089]
【The invention's effect】
As described above, according to the present invention, the surface of the spur holding unit facing the lower surface of the holding unit has a distance between the first surface holding the sensor for detecting the state of the ink tank and the lower surface of the holding unit. It comprises a second surface formed to be farther than the first surface. Thereby, the clearance between the first surface and the holding means can be made as small as possible, so that measurement accuracy by the sensor can be ensured.
[0090]
Further, the holding surface and the second surface including the recovery position or the ink tank replacement position are spaced apart from each other so as not to interfere with each other. In other words, the spur holding means moves toward the holding means when setting the transport tray for supplying a relatively thick recording medium such as cardboard or CD-R. Does not need to worry about the interference between the spur holding means and the holding means, even if it is located at a position facing the second surface. Further, since the holding means is not unnecessarily separated from the platen in order to avoid interference between the holding means and the spur holding means, the recording quality does not deteriorate due to this.
[0091]
Further, in the recording apparatus of the present invention, since the first surface and the second surface are connected by the tapered surface, even if the holding unit runs away due to malfunction, the play of the holding unit and the spur holding unit are bent. As a result, the holding means smoothly rides on the tapered surface, so that the main body is not damaged.
