Description

  The present invention relates to a holding unit equipped with an optical recording medium or conveyance of a thick recording sheet in a recording apparatus.

  Here, an ink jet recording apparatus will be described as a conventional example.

  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.

  In addition, the development of recording inks and recording materials has progressed. In particular, recording materials can be recorded on glossy paper, glossy films, and disk-shaped media in addition to plain paper, such as letters and designs on the surface of CDs (compact discs). There is a growing demand for printing.

  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.

  Recently, there is a print area formed so that it can be directly described with a sign pen, a felt pen, or the like.

  In addition, there is known an apparatus for printing contents to be described in a print area using a personal computer in a CD, and in particular, a personal inkjet printer recently has a CD printing function.

  In such an apparatus, a CD that is a recording medium is mounted on a tray that is a holding member, the tray is inserted into a guide portion of a tray guide that is mounted on the printer body, and is set at a predetermined position, and then the tray is discharged. The paper is fed by a roller, conveyed at one end and upstream, then switched back, conveyed by a pair of conveying rollers, and printed by a recording head.

  In recent years, there is an increasing demand for printing on board paper (thickness of about 1 to 2 mm) and fine art paper (thickness of about 0.3 to 1 mm). Paper is fed from the opening, guided along a substantially straight conveyance path formed in the apparatus, and conveyed by a pair of conveyance rollers for recording.

As another conventional example, Patent Document 1 can be cited.
JP 2004-042392 A

  In the apparatus shown in the above-described conventional example, the tray for holding the recording medium CD is formed of a soft resin such as ABS or PS, and particularly in the driving roller of the pair of conveying rollers for nipping and conveying the tray, In order to convey the recording sheet with high accuracy without causing slippage during normal recording sheet conveyance, a hard ceramic is coated on the metal to form a surface with a high coefficient of friction.

  With the above configuration, when the tray held between the pair of transport rollers is skewed or the durability of CD printing is increased, the surface of the tray is damaged by the ceramic layer on the surface of the driving roller and deteriorates. This ceramic layer was clogged by the resin from which the tray was shaved, which significantly deteriorated the tray conveyance accuracy.

  Further, when the driving roller is clogged, skew and conveyance failure occur in the normal conveyance of the recording sheet, and the recorded image is greatly disturbed or a jam occurs.

  In addition, thick paper such as board paper and fine art paper is transported substantially linearly by a pair of transport rollers, but the drive roller diameter is optimized for transporting ordinary recording sheets (thickness of about 0.3 or less). In the transport of thick paper, the transport amount becomes large, and white streaks tend to occur between print lines during recording.

  The present invention aims to improve the conveyance accuracy of a tray on which a CD that is a recording medium is mounted, a recording head that performs recording on the recording medium, a first conveyance unit that conveys a recording sheet that is a recording medium, The recording sheet has a holding means for holding a recording medium having a different form, and a dedicated second conveying means for conveying the holding means.

  Further, the conveyance path of the holding unit is a part of the same conveyance path as that of the recording sheet.

  Further, the second transport unit is also used as a part of the first transport unit.

  Further, the first conveying means and the second conveying means have the same conveying roller, and are respectively conveyed by different outer diameter portions of the conveying roller.

  Further, the holding member is inserted from the paper discharge port side of the recording apparatus, conveyed to one end and upstream, then switched back and conveyed while recording.

  Further, the second conveying means is a paper discharge roller disposed on the downstream side of the first conveying means.

  The holding member is a thin plate member.

  The recording medium held by the holding member is an optical recording medium.

  In addition, a recording head that performs recording on a recording medium, a first transport unit that uses a first transport path for transporting a recording sheet that is a recording medium fed by a paper feeding device, and a thickness greater than that of the recording sheet In this configuration, a dedicated second transport unit using a second transport path capable of transporting a thick recording medium is provided.

  Further, the transport path of the thick recording medium is partially the same as the transport path of the recording sheet.

  Further, the second transport unit is also used as a part of the first transport unit.

  Further, a thick recording medium is inserted from the discharge port side of the recording apparatus, conveyed to one end and upstream, then switched back and conveyed while recording.

  Further, the second conveying means is a paper discharge roller disposed on the downstream side of the first conveying means.

  The recording head is an ink jet head having an ejection port for ejecting flying droplets of ink.

  The recording head is a head that performs recording by ejecting ink using thermal energy, and is provided with an electrothermal energy converter for generating thermal energy applied to the ink.

  As described above, the ink jet recording apparatus of the present invention is configured to convey the tray by a dedicated conveying unit different from the conveying unit for the recording sheet. Even when the number of transport durability increases, a highly accurate transport can be performed without deteriorating the transport accuracy of the tray, and an apparatus capable of obtaining high image quality and high reliability can be obtained.

  In addition, since the recording roller and the tray are transported by the same transport roller 36 by providing a step in the outer diameter of the transport roller 36, the apparatus has a small number of parts, a low cost, and a small space. Can do.

  In addition, the thick paper transported by the paper discharge roller 41A allows the paper discharge roller diameter to be an optimum diameter matched to the thick paper transport, so that it can be transported with high accuracy and high-quality recording can be obtained. Is.

Example 1
A first embodiment of the present invention will be described with reference to FIGS. A recording apparatus 1 having an automatic paper feeding device includes a paper feeding unit 2, a paper feeding unit 3, a paper discharging unit 4, a carriage unit 5, and a cleaning unit 6. Then, these are divided into items and the outline is described sequentially. 1 is a perspective view showing the overall configuration of the recording apparatus 1. FIG. 2 is a sectional view of the recording apparatus 1 as viewed from the side. FIG. 1 and FIG. Part, (III) carriage part, (IV) cleaning part, and (V) paper discharge part will be described.

(I) Paper Feed Unit The paper feed unit 2 is configured such that a pressure plate 21 on which the recording paper P is stacked and a feeding rotating body 22 that feeds the recording paper P are attached to the base 20. A movable side guide 23 is movably provided on the pressure plate 21 to restrict the stacking position of the recording paper P. The pressure plate 21 can rotate around a rotation axis a coupled to the base 20, and is urged by the pressure plate spring 24 to the feeding rotating body 22. A separation pad 25 made of a material having a large friction coefficient, such as an artificial skin, which prevents double feeding of the recording paper P, is provided at a portion of the pressure plate 21 facing the feeding rotating body 22. Further, the base covers the corners of the recording paper P in one direction, the separation claw 26 for separating the recording paper P one by one, and the base 20 for separating the paper that cannot be used such as the thick paper. The integrally formed bank portion 27, the separation claw 26 operates at the plain paper position, and the switching lever 28 for switching so that the separation claw 26 does not operate at the thick paper position, the contact between the pressure plate 21 and the feeding rotating body 22 is released. A release cam 29 is provided.

  In the above configuration, the release cam 29 pushes the pressure plate 21 down to a predetermined position in the standby state. As a result, the contact between the pressure plate 21 and the feeding rotating body 22 is released. In this state, when the driving force of the conveying roller 36 is transmitted to the feed rotating body 22 and the release cam 29 by a gear or the like, the release cam 29 is separated from the pressure plate 21, so that the pressure plate 21 rises and feed rotation is performed. The body 22 and the recording paper P come into contact with each other, and the recording paper P is picked up and started to be fed with the rotation of the feeding rotating body 22, separated one by one by the separation claw 26, and sent to the paper feeding unit 3. The feeding rotary member 22 and the release cam 29 rotate until the recording paper P is fed into the paper feeding unit 3, and again enter the standby state in which the contact between the recording paper P and the feeding rotary member 22 is released. The driving force from is cut off.

(II) Paper Feed Unit The paper feed unit 3 has a transport roller 36 for transporting the recording paper P and a PE sensor 32. The transporting roller 36 is provided with a driven pinch roller 37 in contact therewith.

  The pinch roller 37 is rotatably held by the pinch roller guide 30, and the pinch roller guide 30 is biased by the pinch roller spring 31, so that the pinch roller 37 is pressed against the transport roller 36 and the transport force of the recording paper P is increased. Producing. Further, an upper guide 33 and a platen 34 for guiding the recording paper P are disposed at the entrance of the paper feeding unit 3 to which the recording paper P is conveyed. Further, the upper guide 33 is provided with a PE sensor lever 35 for transmitting the leading edge and trailing edge detection of the recording paper P to the PE sensor 32.

  In the above configuration, the recording paper P sent to the paper feeding unit 3 is guided by the platen 34, the pinch roller guide 30, and the upper guide 33, and sent to the roller pair of the transport roller 36 and the pinch roller 37. At this time, the leading edge of the recording paper P conveyed by the PE sensor lever 35 is detected, and thereby the printing position of the recording paper P is obtained. Further, the recording paper P is conveyed on the platen 34 by rotating the roller pairs 36 and 37 by an LF motor (not shown).

  The recording head 7 is an easily replaceable ink jet recording head in which an ink tank is detachable. The recording head 7 can apply heat to the ink by a heater or the like. Then, the film of the ink is boiled by this heat, and the ink is ejected from the nozzle 70 of the recording head 7 by the pressure change caused by the growth or contraction of the bubbles due to the film boiling, and an image is formed on the recording paper P.

(III) Carriage unit The carriage unit 5 includes a carriage 50 to which the recording head 7 is attached. The carriage 50 is held by a guide shaft 81 for reciprocating scanning in a direction orthogonal to the conveyance direction of the recording paper P, and a guide rail 82 for holding the rear end of the carriage 50 and maintaining a gap between the recording head 7 and the recording paper P. It is supported. The guide shaft 81 and the guide rail 82 are attached to the chassis 8. The carriage 50 is driven via a timing belt 83 by a carriage motor 80 attached to the chassis 8. The timing belt 83 is stretched and supported by an idle pulley 84. Further, the carriage 50 is provided with a flexible substrate 56 for transmitting the recording head 7 head signal from the electric substrate 9.

  In the above configuration, when an image is formed on the recording paper P, the roller pairs 36 and 37 convey the recording paper P to the row position (position in the conveyance direction of the recording paper P) where the image is formed, and the carriage 50 is moved by the carriage motor 80. The recording head 7 is moved to the row position for image formation (position perpendicular to the conveyance direction of the recording paper P), and the recording head 7 is opposed to the image formation position. Thereafter, the recording head 7 ejects ink toward the recording paper P in response to a signal from the electric substrate 9 to form an image.

  In order to attach / detach the recording head 7 to / from the carriage 50 or attach / detach the ink tank to / from the recording head 7, when the operation key (not shown) is pressed, the carriage 50 moves to a predetermined position, and each attachment / detachment operation is performed at that position. It is like that.

(IV) Cleaning unit The cleaning unit 6 supplies the driving force from the pump 60 for cleaning the recording head 7 and the cap 61 and the conveyance roller 36 for preventing the recording head 7 to dry to the paper feeding unit 2 and the pump 60. The drive switching arm 62 is changed over. When the drive switching arm 62 is other than paper feeding and cleaning, a planetary gear (not shown) that rotates around the axis of the transport roller 36 is fixed at a predetermined position, so that the paper feeding unit 2 and the pump 60 are driven. Power is not transmitted. If the drive switching arm 62 is moved in the direction of arrow A by moving the carriage 50, the planetary gear becomes free, so the planetary gear moves according to the forward rotation and reverse rotation of the conveyance roller 36, and the conveyance roller 36 is normal. The driving force is transmitted to the sheet feeding unit 2 when the sheet is rotated, and the driving force is transmitted to the pump 60 when the sheet is reversed.

(V) Paper Discharge Unit The paper discharge unit 4 is provided with two paper discharge rollers 41 and 41A. The transfer roller 40, the paper discharge roller 41, and the paper discharge roller 41A that are in contact with the transport roller 36 and the paper discharge roller 41 are provided. A transmission roller 40A is provided. Accordingly, the driving force of the transport roller 36 is transmitted to the paper discharge roller 41 via the transmission roller 40, and is transmitted to the paper discharge roller 41A by the transmission roller 41A.

  Further, the spurs 42 and 42A are in contact with the discharge rollers 41 and 41A so that they can be rotated by being driven by the discharge rollers 41 and 41A, and the cleaning roller 44 is rotatably contacted with the spurs 42 and 42A. . With the above configuration, the recording sheet P on which an image is formed by the carriage unit 5 is sandwiched between the discharge rollers 41 and 41A and the spurs 42 and 42a, conveyed, and discharged to the discharge tray 100.
