Description

  The present invention relates to a recording apparatus that is an output device such as a personal computer, and more particularly to an ink jet recording apparatus.

  Conventional recording apparatuses generally use paper as the recording material, but recently, various recording materials such as cardboard and CD-R are increasingly used.

  In order to feed such a wide variety of recording materials, there is an increasing number of cases where an optimum paper feeding method suitable for the type of recording material is provided in the recording apparatus main body.

  FIG. 2 shows a conventional recording apparatus.

  In the figure, 101 is a recording head, 102 is a conveying roller for conveying the recording material in the sub-scanning direction, 103 is a pinch roller for pressing the recording material against the conveying roller 102, and 104 is for guiding the recording material. An upper guide 105, a platen 105, a paper feed roller 106, a separation roller 107 that presses against the paper feed roller and separates sheets one by one, 108 is an intermediate guide, and 109 is a lower guide.

  The paper feed path A shown in the figure is a path by an automatic paper feed mechanism, and this paper feed port is used for normal printing.

  The paper feed path B is a manual feed path, and this paper feed port is used for printing on thick paper or printing only one sheet.

A paper feed path C is a paper feed port for CDR printing, and feeds and prints by inserting a CDR tray from the paper discharge side. A recording apparatus capable of recording on a CD-ROM in this way is disclosed in Patent Document 1, for example.

  However, in the conventional example, the following problems have occurred.

  When paper is fed from the paper feed path A by the automatic paper feed mechanism, image unevenness occurs due to an impact that falls by the step difference of the path B when the rear end of the paper passes the path switching unit 108A of the intermediate guide 108, There has been a problem that a contact sound is generated by the lower guide 109 contacting.

  In order to solve the above problem, there is an example in which a switching flapper or the like is provided in the intermediate guide 108A, but in that case, it is difficult to achieve compatibility with the CDR path C.

  In order to solve this problem, in the present invention, a transport roller for performing sub-scanning of a recording material, a plurality of paper feed paths provided on the upstream side of the transport roller, and a plurality of paper feed paths are switched. Sheet feeding path switching means and a special recording material dedicated path for carrying from the downstream side of the carrying roller, and a partially cutout shape is provided in the width direction of the paper feeding path switching means. The above problem is to be solved.

  According to the present invention, a conveying roller for performing sub-scanning of a recording material, a plurality of sheet feeding paths provided on the upstream side of the conveying roller, and a sheet feeding path switching for switching the plurality of sheet feeding paths. And a special recording material dedicated path for transporting from the downstream side of the transport roller, and there are a plurality of passes by providing a partially cutout shape in the width direction of the paper feed path switching means. In this case, it is possible to secure both normal printing images and a path to be inserted from the paper discharge side such as a CD-R.

(Embodiment 1)
FIG. 1 is a sectional view of a recording apparatus that best represents the features of the present invention.

  A recording head 1 scans in the main scanning direction by a carriage (not shown), and discharges the recording material in synchronization with the scanning.

  2 is a conveyance roller for conveying the recording material in the sub-scanning direction, 3 is a pinch roller for abutting the conveyance roller 2 and pressing the recording material against the conveyance roller 3, and 4 is an upper guide , 5 is a platen, 200 is a first automatic supply unit, 6 is a pickup roller provided in the automatic supply unit 200, and 16 is connected to the pickup roller 6 to separate and convey the recording material 11 one by one. Separating roller 11 for recording, 11 is a recording material set in the automatic feeding unit 20, 15 is a base and paper guide for the automatic feeding unit 20, and 10 is a switching member which is also a feature of the present invention. A flapper, 9 is a lower guide, 300 is a second automatic feeding unit, 14 is a sheet feeding roller / conveyance roller, 17 is a separation roller for separating and conveying recording materials one by one by pressing against the sheet feeding roller 14 , 13 Guide, 300 is a manual feed slot.

FIG. 4 shows a detailed view of the switching flapper. As shown in the figure, the switching flapper 10 can be rotated by its own weight around the rotation fulcrum 10A, and in the normal state, it stops at the lower guide 9 as shown in the figure.

  FIG. 3 shows the shape of the switching flapper 10 in the paper width direction.

  As shown in the figure, the distance from the paper reference to the width H to the width I is cut (10b, the position of the dotted line in FIG. 4).

  This cut shape is just the width of the CD-R tray.

  Further, the width I is set to be equal to or smaller than the A4 width, and the switching flapper 10 can hold both ends of the A4 paper at long portions (10c, 10d).

  The reason why the notched portion is located on the non-reference side with respect to the A4 width is that it is desired to hold a small size paper sheet such as an L plate or a postcard by the long portion (10c) of the flapper 10.

  Next, the operation of this recording apparatus will be described.

  The recording material 11 set in the first automatic feeding unit 200 is separated one by one by the pickup roller 6 and the separation roller 16 and conveyed to the nip portion of the conveyance roller 2 and the pinch roller 3.

  Thereafter, the recording material conveyed by the conveying roller pair is recorded by the recording head 1.

  The recording material is sequentially recorded by the main scanning printing of the recording head and the sub-scanning operation by the conveying roller pair, and the switching flapper 10 is provided when the rear end of the recording material leaves the base 15 of the automatic feeding unit. The rear end can pass smoothly.

  The recording material 12 set in the second automatic feeding unit 300 is separated and conveyed one by one by the pickup rollers 14 and 17.

  After that, the paper passes through the paper passing paths F and E, and passes through the switching flapper unit 10. Since the switching flapper is held by its own weight, it is transported by its own weight (FIG. 5).

  On the other hand, in the case of CDR printing, a CDR tray is inserted from the paper discharge side to perform printing.

  FIG. 6 shows the state. At this time, since the CDR tray passes between the 10b portions of the switching flapper, the CDR tray can be conveyed without performing the operation of the switching flapper.

(Embodiment 2)
7 and 8 show a second embodiment of the switching flapper.

  As shown in the figure, a portion 18B and a portion 18C are provided around the rotation fulcrum 18A of the switching flapper 18, and the shape is determined so as to be balanced by its own weight shown in FIG. In the figure, G indicates the position of the center of gravity of the switching flapper 18.

  Further, the lower guide 9 is provided with a notch shape 9A, and the notch shape is such that it escapes when the 18B portion of the switching flapper rotates.

  As shown in FIG. 8, the portion 18B is arranged on the rib, and a notch shape 9A of the lower guide is provided so as to face the position.

  The operation will be described.

  FIG. 9 shows a state in which the rear end of the recording material fed one by one from the automatic feeder 200 passes through the switching flapper 18 part.

  As shown in the figure, when passing through the switching flapper 18, the switching flapper 18 slightly rotates depending on the rigidity of the recording material, but the trailing edge of the recording material can be held, which can solve image unevenness and other problems. it can.

  FIG. 10 shows a state where the sheet is conveyed from the second automatic feeding apparatus 300.

  As shown in the figure, the switching flapper 18 rotates in the direction of the arrow to form a path.

  At this time, since the recording material 12 has only the resistance of its own weight of the switching flapper 18 as the resistance, it is very small and does not affect the image or the like.

  FIG. 11 shows the state of CD-R printing.

  As shown in the figure, the CD-R or CD-R tray inserted from the paper discharge side is conveyed by the conveyance roller from the left side to the right side shown in the figure.

  At this time, the switching flapper 18 is rotated by the CD-R tray and rotated to the state shown in the figure.

  The path portion 18B of the switching flapper 18 can pass through the notch shape of the lower guide 9A and rotate to the state shown in the figure.

  When the conveyance and printing are completed, the switching flapper 18 returns to the original state by its own weight because the position of the center of gravity G is in the state shown in the figure.
