Description

  The present invention relates to a recording apparatus.

Some recording devices such as printers include a feeding unit that feeds paper to the main device side, and a paper storage device that accommodates a large amount of paper separately from the main device (for example, a patent) Reference 1).
In such a recording apparatus, a cover that can be opened and closed is provided on the side of the main body on which the paper storage device is provided. When a so-called paper jam occurs in the paper conveyance path, the cover is opened and the paper is opened. Some are trying to get rid of. When the paper is fed from the feeding unit with the cover closed, the paper stored in the paper storage device passes through the through hole provided in the cover and is fed into the main body device.

  FIG. 12A is a view showing a cross section of an upper cover 80 and a lower cover 81 that are provided on the outside of the main body so as to be opened and closed. FIG. 12A is a view of the conveyance path 84 as viewed from the width direction of the sheet P1 conveyed. The upper cover 80 and the lower cover 81 are in a closed state. The upper cover 80 and the lower cover 81 are provided side by side in the vertical direction Z. Outside the upper cover 80 and the lower cover 81, a paper storage device 86 that stores a plurality of papers P2 is provided. The paper storage device 86 feeds the paper P2 to the main body device one by one. The sheet P2 fed into the main body apparatus enters the conveyance path 84.

  When the paper P1 transported from the lower side of the transport path 84 toward the upper side remains on the lower side of the transport path 84, the paper storage device 86 is removed from the main body device, and the lower cover 81 is opened to open the paper. Remove P1. When the paper P1 transported from the lower side of the transport path 84 to the upper side of the transport path 84 or the paper P2 fed by the paper storage device 86 remains on the upper side of the transport path 84, the upper cover 80 is opened. The sheets P1 and P2 are removed.

  The lower cover 81 is provided with a through hole 82 that obliquely penetrates the side surface 83. A guide path 85 indicated by a broken line guides the paper P <b> 2 passing through the through hole 82 to the transport path 84.

  The inclination angle Q indicates an angle in the conveyance direction of the guide path 85 with respect to the conveyance direction (vertical direction Z) of the conveyance path 84. That is, the inclination angle Q is an entry angle when the paper P2 fed from the paper storage device 86 enters the transport path 84 through the through hole 82 and the guide path 85. When feeding the paper P2, since the deformation of the paper P2 is reduced, it is preferable that the inclination angle Q (invasion angle) is small. However, if the inclination angle Q is to be reduced, the guide path 85 and the upper cover 80 may interfere with each other as shown in FIG. 12A.

Therefore, as shown in FIG. 12B, in order not to interfere with the upper cover 80, the inclined portion 82a1 positioned below the through hole 82 in FIG. 12A and the inclined portion 82a1 are joined and horizontally at the position of the opening 87. It is conceivable to include a lower cover 81a in which a through hole 82a having a horizontal portion 82a2 that extends is formed.
Alternatively, as shown in FIG. 12C, the inclined portion 82 b 1 positioned on the transport path 84 side from the upper cover 80 and the inclined portion 82 b 1 are joined so as not to interfere with the upper cover 80, and horizontally at the position of the opening 87. It is conceivable to include a lower cover 81b formed with a through hole 82b having a horizontal portion 82b2.

  FIG. 1 is a diagram illustrating a schematic configuration of a printer 100 that is an example of a recording apparatus. The printer 100 is an ink jet printer that records images such as characters and photographs by attaching ink as a liquid to the paper P.

  The paper cassette 103 accommodates the paper P in a stacked state, and is detachably attached to the housing 101 of the main body apparatus. In the printer 100 of this embodiment, four paper cassettes 103 are arranged in the vertical direction Z.

  Inside the housing 101, a recording unit 110 that performs recording on the paper P from above, and a transport unit 130 that transports the paper P in the transport direction X along the transport path 120 are provided.

  The recording unit 110 includes a line head type recording head 111 capable of simultaneously discharging ink over substantially the entire area in the width direction Y. The recording unit 110 forms an image on the paper P by the ink ejected from the recording head 111 being attached to the recording surface (the surface on which the image is printed) facing the recording head 111 on the paper P.

  The conveyance unit 130 includes a plurality of conveyance roller pairs 131 arranged along the conveyance path 120 and a belt conveyance unit 132 provided immediately below the recording unit 110. Ink is ejected from the recording head 111 to the sheet P being conveyed by the belt conveying unit 132, and recording is performed.

  The belt transport unit 132 is disposed on the upstream side in the transport direction X (right side in the drawing) with respect to the recording head 111 and the driven roller 133 is disposed on the downstream side in the transport direction X with respect to the recording head 111 (on the left side in the drawing). It has a roller 134 and an annular belt 135 that is endless and is hung on each of the rollers 133 and 134. When the driving roller 133 is driven to rotate, the belt 135 circulates, and the paper P is conveyed downstream in the conveying direction X by the rotating belt 135. That is, the outer peripheral surface of the belt 135 functions as a support surface that supports the paper P on which recording is performed.

  The conveyance path 120 is branched from the supply path 140 through which the sheet P is conveyed toward the recording unit 110, the discharge path 150 in which recording is performed by the recording unit 110 and the recorded sheet P is conveyed, and the discharge path 150. Branching path 160 to be connected.

  The supply path 140 includes a first supply path 141, a second supply path 142, and a third supply path 143. The first supply path 141 is a supply path through which the insertion port 141b is exposed by opening the cover 141a provided on the right side surface of the housing 101, and the sheet P inserted from the insertion port 141b is conveyed to the recording unit 110. It is. A first drive roller pair 144 is provided in the first supply path 141, and the sheet P inserted from the insertion port 141 b is linearly directed toward the recording unit 110 by the rotational drive of the first drive roller pair 144.

The driving roller 146a is attached to the housing 101 side, and the driven roller 146b is attached to the upper cover 170 and the lower cover 180, respectively. In a state where the upper cover 170 and the lower cover 180 are closed, the driven roller 146b can be rotated by being driven by the driving roller 146a.

  The third supply path 143 is a supply path through which the sheet P on which one side is recorded by the recording unit 110 is conveyed again to the recording unit 110 when performing double-sided printing in which images are recorded on both sides of the sheet P. is there. That is, a branch path 160 that branches from the discharge path 150 is provided on the downstream side in the transport direction X from the recording unit 110. When performing duplex printing, the paper P is conveyed to the branch path 160 by the operation of the branch mechanism 147 provided in the middle of the discharge path 150. Further, the branch path 160 is provided with a branch path roller pair 161 capable of both normal rotation and reverse rotation on the downstream side of the branch mechanism 147.

  At the time of duplex printing, the paper P on which one side is printed is once guided to the branch path 160 by the branch mechanism 147 and conveyed downstream in the branch path 160 by the pair of branch path rollers 161 rotating in the forward direction. Thereafter, the sheet P conveyed to the branch path 160 is reversely transported from the downstream side to the upstream side in the branch path 160 by the branch path roller pair 161 that is reversed.

  The sheet P that is reversely conveyed from the branch path 160 is conveyed to the third supply path 143 and is conveyed toward the recording unit 110 by a plurality of conveyance roller pairs 131. The third supply path 143 bypasses the recording unit 110 and merges with the first supply path 141 and the second supply path 142 on the upstream side of the recording unit 110.

  For this reason, by being conveyed through the third supply path 143, the sheet P is reversed so that the other surface on which the printing is not performed faces the recording unit 110, and the recording unit is rotated by the third driving roller pair 148. It is conveyed toward 110. That is, the third supply path 143 functions as a reverse transport path for transporting the paper P while reversing the posture of the paper P in the vertical direction Z.

  The sheet P conveyed through the supply paths 141, 142, and 143 is conveyed to the alignment roller pair 149 disposed upstream of the recording unit 110 in the conveyance direction, and then is transferred to the alignment roller pair 149 that has stopped rotating.
