Description

  The present invention relates to printing on an optical recording medium 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 a device for printing contents to be described in a printing area using a personal computer in a CD, and in recent years, a CD printing unit is set as an accessory so that it can be detachably attached to a printer body even in a personal inkjet printer. Some have been done.

  In such an apparatus, as described in Patent Document 1, a CD as a recording medium is loaded into a holding member, and the holding member is inserted into a guide portion of a support member mounted on the printer main body, and is moved to a predetermined position. After setting, the holding member is nipped and conveyed by a pair of conveying rollers and printed by a recording head.

  FIG. 11 is a diagram showing a conventional example, in which a support member 103 that can be attached to and detached from the printer main body is mounted, and a holding member 106 loaded with a CD is set on the upper surface of the support member 103.

  The holding member 106 is pressed from above by a spring (not shown) by rollers 108A and 108B and roller holders 107A and 107B.

Accordingly, the holding member 106 is pressed against the paper discharge roller 41A and is conveyed in the direction of the arrow by the conveyance force of the paper discharge roller 41A.
JP 2002-308493 A

  In the apparatus shown in the above-described conventional example, the support member that supports and guides the holding member that holds the CD can be attached to and detached from the printer main body. Since the member had to be removed from the printer main body, it was not excellent in operability.

  Further, since the support member is not used except during CD printing, the support member may be lost.

  As a solution to these disadvantages, there is a paper discharge tray that also serves as a support member. The paper discharge tray supports the holding member during the CD printing and the first position for holding the recording paper printed. Some of them are configured to be movable to a second position.

  Such movement of the movable paper discharge tray from the first position to the second position is a method in which the paper discharge tray is gripped with a finger and tilted upward and lifted obliquely upward. It was difficult to grasp, fingers were slippery from the paper discharge tray, the angle and position of the diagonally upward lifting were difficult to understand, and a large operating force was required, so the operability was not very good.

  SUMMARY OF THE INVENTION An object of the present invention is to provide excellent operability when printing on a CD as a recording medium, and a first method for holding an image forming unit and a sheet material image-formed by the image forming unit. And a holding means for holding a recording medium having a different form from the sheet material, and the holding means is a discharge tray when printing on a recording medium having a different form from the sheet material. The recording apparatus supported at the second position includes an operation member that moves the discharge tray from the first position to the second position and / or moves from the second position to the first position. Is.

  An image forming unit; a paper discharge tray having a first position for holding a sheet material image-formed by the image forming unit; and a holding unit for holding a recording medium having a different form from the sheet material. And the holding means is supported at the second position of the discharge tray when printing on a recording medium having a form different from that of the sheet material, and the discharge tray is moved from the first position to the second position. The operation member is moved to the first position, and the movement of the discharge tray from the second position to the first position is performed by operating the discharge tray.

  The operation member is a lever.

  The operation member is a push button.

  Further, the recording medium is an optical recording medium, and the holding means is a thin plate member.

  In the ink jet recording apparatus of the present invention, when printing on a CD, the discharge tray 100 can be raised and set to the CD printing position with a simple operation by simply pulling down the operation lever 202, so that the operation is very easy to understand. Therefore, it is possible to make a device with excellent operability without requiring a large operating force.

  In addition, when returning from the CD printing state to the normal printing state, the operation is completed only by lifting the discharge tray 100, so that the operation is very easy to understand, does not require a large operating force, and can be an apparatus with excellent operability.

  Further, since the spur base 43 also moves up / down in conjunction with the paper discharge tray 100, a simple mechanism with low cost and high reliability can be achieved.

  A first embodiment of the present invention will be described with reference to FIGS.

(Embodiment 1)
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 acts at the plain paper position, and the contact between the pressure plate 21 and the feeding rotating body 22 is released to switch the separation claw 26 so that the separation claw 26 does not act at the thick paper position. 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 Part The carriage part 5 has a carriage 50 to which the recording head 7 is attached. The carriage 50 is held by a guide shaft 82 for reciprocating scanning in a direction orthogonal to the conveyance direction of the recording paper P, and a guide rail 82 for maintaining the gap between the recording head 7 and the recording paper P by holding the rear end of the carriage 50. 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 that cleans the recording head 7 and the cap 61 and the transport roller 36 for suppressing the drying of the recording head 7 to the sheet 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 due to the movement of the carriage 50, the planetary gear becomes free, so the planetary gear moves according to the forward and reverse rotations of the transport roller 36, and the transport roller 36 moves forward. 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 contact 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.
