Description

[Technical field]

[0001] The technique of the present disclosure relates to an image forming apparatus including a recording unit that records on a recording medium. [Background technology]

[0002] Some image forming devices that record on sheet material as a recording medium are equipped with a recording means that records on the sheet material and a reading means that reads an original, and have a paper feed port for supplying the sheet material to the recording means provided at the upper rear of the device body.

[0003] There is also an image forming apparatus in which the reading means is arranged to be rotatable and openable relative to the upper part of the recording means (for example, Patent Document 1). The reading means includes a document cover that opens and closes a document table that reads a document, and the document cover is provided so as to be rotatable and openable relative to the reading means.

[0004] In addition, the paper feed port is provided with an opening / closing cover that serves as a lid to cover the paper feed port, and by covering the paper feed port with the opening / closing cover when the recording means is not in use, it is possible to prevent foreign objects from falling into the paper feed port.

[0005] However, when the image read by the reading means is recorded on a sheet material by the recording means, the reading means is operated with the access cover open and the paper feed opening open. For example, if the reading means is operated with a foreign object such as a paper clip placed on the document cover, the foreign object may fall into the paper feed opening provided at the upper rear of the device body.

[0006] Therefore, the image forming apparatus of Patent Document 1 is provided with a restricting member for preventing foreign objects from falling, separate from the opening / closing cover that covers the paper feed port. This restricting member is housed inside the opening / closing cover when the opening / closing cover is closed. This image forming apparatus is provided with a biasing member that biases the restricting member to a position that prevents foreign objects from falling when the opening / closing cover is open.

[0013] Preferred embodiments of the technology of the present disclosure will be described in detail below with reference to the accompanying drawings. In each drawing, the same reference numerals are used for the same components, and duplicated descriptions will be omitted. Each embodiment will be described in more detail below. The numerical values ​​shown in each of the following examples are merely examples, and the technology of the present disclosure is not limited to these. The technology of the present disclosure is not limited to each embodiment, and includes combinations of these embodiments and applications to other technical fields.

[0014] (First embodiment) An image forming apparatus according to a first embodiment of the technique of the present disclosure will be described below. Figs. 1 and 2 are perspective views showing an inkjet recording apparatus 10 as an example of an image forming apparatus according to this embodiment. In each figure, a coordinate system consisting of an X-axis, a Y-axis, and a Z-axis that are orthogonal to each other is set. In the figures, it is assumed that the inkjet recording apparatus 10 is placed on a surface parallel to the XY plane. The negative direction of the Z-axis is the direction of gravity.

[0015] The inkjet recording device 10 has a housing 11 having a substantially rectangular parallelepiped shape. As shown in FIG. 2A, the housing 11 has a front surface on the negative side of the Y axis among the surfaces parallel to the XZ plane, and a back surface on the positive side of the Y axis. The housing 11 also has a side surface parallel to the YZ plane, a bottom surface on the negative side of the Z axis among the surfaces parallel to the XY plane, and an upper surface on the positive side of the Z axis. The inkjet recording device 10 also includes a paper feed means 30 that supplies a sheet material as a recording medium to a recording means 33 (described later) contained in the housing. The paper feed means 30 has a paper feed port 301 (supply port) for the sheet material on the upper surface of the inkjet recording device 10. The sheet material is transported from the paper feed port 301 in the negative direction of the Y axis by a separation means (not shown), and is transported to the transport means 31 by a feeding means and a transport path (not shown). The fed sheet material is transported in the negative direction of the Y axis through recording means 33 by transport means 31 and paper discharge means 32 which is driven synchronously with the transport means 31 .

[0016] In this embodiment, for convenience of explanation, two sizes are used as the sizes of the sheet material, and the sheet material (first recording medium) of the smallest size (paper size 1) and the sheet material of the largest size (paper size 2) are fed by the paper feed means 30. It is assumed that a sheet material (second recording medium) of size 1 (paper size 2) is fed. As an example, paper size 1 is a postcard size, and paper size 2 is an A4 size. However, the sizes of sheet materials recordable in the inkjet recording device 10 are at least two different sizes, and may be sizes other than paper sizes 1 and 2, or may be three or more sizes.

[0017] The recording means 33 between the conveying means 31 and the paper discharge means 32 is provided with a carriage 34 that moves back and forth along the sheet material. The carriage 34 is equipped with a recording head (not shown). The recording head discharges ink from an ink cartridge 36 that contains ink for printing onto the sheet material based on recording information acquired by the inkjet recording device 10 to record an image. In the inkjet recording device 10, a platen 35 is disposed at a position facing the recording means 33 in the direction of gravity to guide and support the sheet material during image recording. Then, the sheet material on which image recording has been completed is discharged by the paper discharge means 32 onto a paper discharge tray 37 that is provided in a movable manner outside the device main body.

[0018] The inkjet recording apparatus 10 is provided with a paper feed cassette 38 for stacking sheet materials in addition to the paper feed means 30. Of the sheet materials stacked in the paper feed cassette 38, the topmost sheet material in the paper feed cassette 38 is separated and transported in the positive direction of the Y axis by a separation means (not shown), and is fed to the transport means 31 by the paper feed means 30 and a transport path (not shown). The user can select whether to use the paper feed means 30 or the paper feed cassette 38 to feed the sheet material by operating an input unit (not shown) of the inkjet recording apparatus 10.

[0019] Next, the opening / closing cover 20 provided to the paper feed port 301 in an openable and closable manner will be described with reference to the drawings. The opening / closing cover 20 rotatably moves between a closed position where the paper feed port 301 is closed and an open position where the paper feed port 301 is opened. The opening / closing cover 20 shown in FIGS. 2A and 2B shows a state where it is moved to the closed position where the paper feed port 301 is closed. Also, FIG. 3A is a perspective view of the inkjet recording device 10 in a state where the opening / closing cover 20 is moved to the open position where the paper feed port 301 is opened, and FIG. 3B is a side view thereof. Also, FIG. 4A is a perspective view of the inkjet recording device 10 in a state where a stacking tray 302 (stack tray) that can be accommodated in the paper feed port 301 of the paper feed unit 30 is extended from the paper feed port 301 to the outside of the device, and FIG. 4B is a side view thereof. FIG. 5A is a perspective view of inkjet recording apparatus 10 in a state in which opening / closing cover 20 has been moved to the closed position when stacking tray 302 has been pulled out from paper feed port 301 to the outside of the apparatus, and FIG. 5B is a side view thereof.

[0020] As shown in FIGS. 3A and 3B, the paper feed opening 301 is provided with an opening / closing cover 20 (first opening / closing body), and the opening / closing cover 20 can open and close the paper feed opening 301 by rotating around a predetermined rotation axis, i.e., the rotation axis 201. The rotation axis 201 of the opening / closing cover 20 extends parallel to the longitudinal direction of the paper feed opening 301, which is a long rectangular opening, when viewed from above the inkjet recording apparatus 10. As shown in FIG. 2A, the rotation axis 201 is divided into three rotation axes, but it may be configured as a single rotation axis that extends in the longitudinal direction (X-axis direction) of the opening / closing cover 20. When feeding a sheet material to the recording means 33 by the paper feeding means 30, the user first moves the opening / closing cover 20 to the open position.

[0021] The sheet feeding means 30 has an extendable stacking tray 302 housed within the supply port, i.e., the sheet feed port 301. The stacking tray 302 is movable between a position housed within the sheet feed port 301 and a position pulled out from the sheet feed port 301 to allow sheet materials to be stacked thereon. After moving the opening / closing cover 20 to the open position, the user extends and pulls out the stacking tray 302 to the outside of the device (FIGS. 4A and 4B). Pulling out the stacking tray 302 allows sheet materials of paper size 2, which is a larger size, to be loaded on the stacking tray 302. As shown in FIGS. 5A and 5B, when the stacking tray 302 is pulled out, the user opens and closes the opening / closing cover 20. By moving the bar 20 toward the closed position, the opening and closing cover 20 prevents foreign matter from entering the paper feed opening 301, while the paper feed means 30 can transport the sheet material.

[0022] Next, the reading means 39 of the inkjet recording device 10 will be described with reference to the drawings. FIG. 6A is a perspective view of the inkjet recording device 10 in a state where a flat-shaped document cover 40 (second opening / closing body) that covers the document table 391 of the reading means 39 in an openable and closable manner is opened, and FIG. 6B is a side view thereof. FIG. 7A is a perspective view of the inkjet recording device 10 in a state where the document cover 40 is closed and the reading means 39 is opened together with the document cover 40, and FIG. 7B is a side view thereof. FIG. 8A is a top view of the inkjet recording device 10 in a state where the stacking tray 302 is accommodated, the opening / closing cover 20 is moved to the closed position, and the document cover 40 is closed. FIG. 8B is a partial cross-sectional view showing a cross-section taken along line aa in FIG. 8A, and FIG. 8C is a partial cross-sectional view showing a cross-section taken along line bb in FIG. 8A.

[0023] The upper part of the inkjet recording device 10 is provided with a reading means 39 for reading an original. The reading means 39 includes a document table 391 for reading an original, and a document cover 40 that rotates around the document table 391 so as to be openable and closable. The document cover 40 rotates around a rotation shaft 401 of the document cover 40 provided on the reading means 39, and an original can be set on the document table 391. The rotation shaft 401 of the document cover 40 is disposed so as to extend parallel to the rotation shaft 201 of the opening and closing cover 20. In addition, the reading means 39 is provided with a rotation shaft (not shown) on the inkjet recording device 10, and the reading means 39 can rotate around the rotation shaft. For example, when replacing the ink cartridge 36 of the recording means 33 or when a sheet material is jammed in the paper feed means 30, the user can open the reading means 39 to perform the work.

[0024] Next, the relationship between the sheet materials loaded on the loading tray 302 and the opening / closing cover 20 will be described. FIG. 9A is a top view of the inkjet recording apparatus 10 in a state where the loading tray 302 is pulled out and the opening / closing cover 20 is moved to the open position. FIG. 9B is a top view of the inkjet recording apparatus 10 in a state where the loading tray 302 is pulled out and the opening / closing cover 20 is moved to the closed position. FIG. 9C is a partial cross-sectional view showing a cross section taken along line cc in FIG. 9B. FIG. 10A is a perspective view showing the bottom surface of the opening / closing cover 20, and FIG. 10B is a plan view showing the bottom surface of the opening / closing cover 20. FIG. 11A is a perspective view of the inkjet recording apparatus 10 in a state where the sheet materials are loaded on the loading tray 302, and FIG. 11B is a side view thereof.

[0025] The rotation shaft 401 of the document cover 40 is provided on the side of the paper feed opening 301, and when the document cover 40 is opened, the upper surface of the document cover 40 becomes a slope that descends toward the paper feed opening 301. The rotation shaft 201 of the opening / closing cover 20 is provided on the document cover 40 side (the second opening / closing body side) with respect to the paper feed opening 301. Therefore, when the stacking tray 302 is pulled out and sheets are loaded on the tray, and the opening / closing cover 20 is moved to the closed position with the paper feed opening 301 open (FIGS. 11A and 11B), the paper feed opening 301 is covered by the opening / closing cover 20. As a result, when the document cover 40 is opened with a foreign object such as a paper clip placed on the document cover 40, the foreign object moves on the document cover 40 toward the paper feed opening 301, but the foreign object is prevented from moving into the paper feed opening 301 by the opening / closing cover 20.

[0026] Furthermore, a protrusion 202 that abuts against the stacking tray 302 is provided on the underside of the opening / closing cover 20, i.e., the surface facing the paper feed port 301. When the opening / closing cover 20 is closed with the loading tray 302 open, the protrusion 202 abuts against an area outside the paper loading range of the loading tray 302 for the sheet material. The area outside the paper loading range that the protrusion 202 abuts against is an area outside the paper loading range in a direction perpendicular to the conveying direction when the sheet material loaded on the loading tray 302 is conveyed to the recording means 33. In this way, when the loading tray 302 is pulled out and moved from the position accommodated in the paper feed port 301 to a position where the sheet material can be loaded, the opening / closing Cover 20 rotates around rotation shaft 201, and protrusion 202 hits an area outside the paper loading range of loading tray 302. This ensures a gap for sheet materials between loading tray 302 and opening / closing cover 20 in the paper loading range. In addition, the height of protrusion 202 from the bottom surface of opening / closing cover 20 is set to a height that prevents opening / closing cover 20 from coming into contact with sheet materials even when the maximum number of sheet materials that can be loaded on loading tray 302 is loaded in a state in which protrusion 202 is in contact with loading tray 302. With protrusion 202 configured as described above, opening / closing cover 20 can prevent foreign objects from falling into paper feed opening 301.

[0027] Furthermore, a paper feed roller 203 is provided on the lower surface of the opening / closing cover 20. The paper feed roller 203 is a medium contact member that is provided so as to be able to come into contact with the sheet material. When the opening / closing cover 20 is moved to the closed position with a predetermined number or more of sheet materials stacked on the stacking tray 302, the paper feed roller 203 comes into contact with the sheet materials stacked on the tray. When less than a predetermined number of sheet materials are stacked on the stacking tray 302, the paper feed roller 203 and the sheet materials are in a positional relationship such that they do not come into contact with each other. If the height of the protruding portion 202 is increased so that the opening / closing cover 20 and the sheet materials do not come into contact with each other even when the maximum number of sheet materials that can be stacked is stacked on the stacking tray 302, the opening / closing cover 20 may get in the way when a user accesses the paper feed port 301. On the other hand, if the opening / closing cover 20 is configured to have the paper feed roller 203 without the protruding portion 202, the sheet materials stacked on the stacking tray 302 may come into contact with the paper feed roller 203, which may increase the conveying resistance of the sheet materials, resulting in conveying failure. In this embodiment, the above-mentioned convex portion 202 is provided on the opening / closing cover 20 that closes the paper feed port 301, so that it is possible to prevent foreign objects from falling into the paper feed port 301 and ensure the usability of the paper feed port 301 without complicating the configuration of the device. In addition, the paper feed rollers 203 are provided on the opening / closing cover 20, so that the conveying performance of the paper feed means 30 is not degraded.

[0028] 9C shows the positions of the upper ends of the sheet materials of paper size 1 and paper size 2 when they are loaded on the loading tray 302. In this embodiment, the feed roller 203 is disposed on the opening / closing cover 20 so that the feed roller 203 is located approximately midway between the upper end of the paper size 1 and the upper end of the paper size 2 when the opening / closing cover 20 is moved to the closed position and the protrusion 202 is in contact with the loading tray 302. Also, when the sheet material of paper size 1 is fed back by the paper feed means 30, the feed roller 203 is disposed on the opening / closing cover 20 so as not to come into contact with the sheet material. Therefore, when the sheet material is loaded on the loading tray 302, the feed roller 203 comes into contact with the sheet material of paper size 2 at a midway position between the end of the sheet material of paper size 1 opposite to the conveying direction and the end of the sheet material of paper size 2 opposite to the conveying direction.

[0029] Therefore, in the present embodiment, when feeding a sheet material of paper size 1 smaller than paper size 2, the paper feed roller 203 does not contact the sheet material, and when feeding a sheet material of paper size 2, it contacts the sheet material to assist in transporting the sheet material. Also, since the sheet material of paper size 1 is smaller than paper size 2, if the paper feed roller 203 contacts the sheet material when feeding the sheet material of paper size 1, there is a possibility that the paper feed roller 203 gets caught on the sheet material and the transport of the sheet material is inhibited. However, according to the arrangement of the paper feed roller 203 in the present embodiment, there is no concern that such a phenomenon of inhibiting the transport of the sheet material will occur.

[0030] Also, FIG. 9C shows a state in which the opening / closing cover 20 is moved to the closed position and the convex portion 202 abuts on the stacking tray 302 with the stacking tray 302 open. At this time, the distance L1 between the stacking tray 302 and the paper feed roller 203 is shorter than the distance L2 between the stacking tray 302 and the end portion 204 of the opening / closing cover 20. Here, the distance L1 is the shortest distance between the surface of the paper feed roller 203 and the placement surface of the sheet material on the stacking tray 302. Also, the end portion 204 of the opening / closing cover 20 is the end portion on the side opposite to the end portion where the rotation shaft 201 of the opening / closing cover 20 is provided. And the distance L2 is the shortest distance between the end portion 204 of the opening / closing cover 20 and the placement surface of the sheet material on the stacking tray 302 is. Therefore, the opening / closing cover 20 and the paper feed roller 203 are configured such that L1 < L2. Thereby, even if a sheet material of paper size 2 with a predetermined number or more is stacked on the stacking tray 302 and the paper feed roller 203 contacts the sheet material, the opening / closing cover 20 can be prevented from contacting the sheet material.

[0031] 9A and 9B, the protrusion 202 of the opening / closing cover 20 is disposed on the left side (negative side of the X axis) facing the front of the inkjet recording device 10, that is, on the negative side of the Y axis among the planes parallel to the XZ plane. As shown in FIGS. 9A and 9B, on the upper surface of the housing 11, the opening / closing cover 20 is disposed on the rear side of the housing 11 (right side of the drawing), and the document cover 40 is disposed on the front side of the housing 11 (left side of the drawing). The protrusion 202 is disposed on the left side (upper side of the drawing) facing the front of the housing 11 in the opening / closing cover 20. This makes it possible to expect that when a right-handed user opens the opening / closing cover 20 to access the paper feed port 301, the protrusion 202 is unlikely to get in the way of the user's work, and thus to prevent a decrease in usability.

[0032] 8B and 8C, when the loading tray 302 is accommodated in the paper feed port 301 and the opening / closing cover 20 is moved to the closed position, the convex portion 202 is disposed on the opposite side of the rotation shaft 201 with respect to the paper feed port 301. Also, FIGS. 7A and 7B show a state in which the loading tray 302 is accommodated in the paper feed port 301 and the opening / closing cover 20 is moved to the closed position and the reading means 39 is opened. When the reading means 39 is opened, the opening / closing cover 20 in the closed position moves to the open position side, and the convex portion 202 moves to the rear side of the device, that is, to the positive direction of the Y axis, as shown in FIGS. 7A and 7B. Therefore, by disposing the convex portion 202 on the opening / closing cover 20 as described above, it is possible to prevent the convex portion 202 from interfering with the loading tray 302 even when the reading means 39 is open.
