Description of the Related Art Conventionally, image recording apparatuses such as printers and multifunction machines having a printing function, a scan function, a copy function, and a fax function have been provided. In this type of image recording apparatus, a main body, a tray body that is movably attached to a lower portion of the main body and on which a recording medium can be placed, and an image that is disposed above the tray body and is placed on the recording medium. Some include a recording unit for recording, a paper feed conveyance path in which a vertical section connecting the tray body and the recording unit is formed in an arc shape, and a paper discharge conveyance path for discharging a recording medium from the recording unit. The recording medium placed on the tray body is sent out to a paper feed conveyance path by a feeding section provided between the recording section and the tray body.

  For example, the feeding unit includes a sheet feeding roller supported by the main body so as to be swingable in the vertical direction and biased downward by an elastic member or the like. The paper feed roller is pressed against the recording medium placed on the tray body and rotated to send the recording medium to the paper feeding conveyance path.

  In the above-described image recording apparatus, the second tray body can place the second recording medium having a size different from that of the first recording medium on the main tray on which the first recording medium can be placed. There is one that is configured in two upper and lower stages with trays. The first recording medium is, for example, A4 or B5 size recording paper, and the second recording medium is, for example, a sealed letter or a postcard. The second tray slides on the main tray between a first posture interrupted between the lower main tray and the feeding unit and a second posture separated from the feeding unit. When the second tray is in the second posture, the feeding unit is pressed by the first recording medium placed on the lower main tray, and sends the first recording medium to the paper feed conveyance path. When the second tray is in the first posture, the feeding unit is pressed by the second recording medium placed on the upper second tray, and sends the second recording medium to the paper feed conveyance path. When the user wants to record an image on a postcard or a sealed letter, the user places the postcard or the sealed letter on the second tray and slides the second tray to the first posture.

  In this type of image recording apparatus provided with a tray body having two upper and lower stages, a sheet feeding tray portion on which a second recording medium can be placed on a second tray, and a recording medium discharged from a paper discharge conveyance path And a paper discharge unit that supports the paper (for example, see Patent Document 1). In the image recording apparatus described in Patent Document 1, the paper discharge unit of the second tray is disposed below the discharge port of the paper discharge conveyance path. The recording medium discharged from the paper discharge conveyance path falls from the front end side in the conveyance direction to the paper discharge unit, and the front end slides on the paper discharge unit or the recording medium discharged first to the paper discharge unit. It will be piled up.

  Incidentally, some image recording apparatuses are provided with a reverse conveyance path that connects a paper feed conveyance path and a paper discharge conveyance path. The reverse conveyance path is provided, for example, so as to pass through a housing provided in the recording unit. The recording medium on which the image is recorded on the front side by the recording unit enters the paper discharge conveyance path, then the traveling direction is reversed and enters the reverse conveyance path, the front and back are reversed, and is sent to the recording unit again.

  When the above-described reverse conveyance path is provided in the image recording apparatus described in Patent Document 1 to add a double-sided printing function, or a mechanism or a substrate for adding other functions is provided in the recording unit, the reverse conveyance is performed. The height dimension of the housing is increased by the space occupied by the path and the mechanism. When the height of the housing increases, the second tray sinks under the housing, so that the vertical separation between the paper discharge section provided on the second tray and the paper discharge transport path increases. Therefore, depending on the type of recording medium, such as weak recording paper, the usage environment such as humidity, and the printing density of the recording medium, the recording medium hangs down from the discharge conveyance path and is discharged. There is a possibility that the leading edge of the medium does not slide on the paper discharge unit or the recording medium that has been discharged first, and the recording medium is rounded, bent, or reversed, and the recording medium is not normally discharged.

  It is conceivable that the height of the paper discharge unit is set higher than that of the paper feed tray that sinks under the recording unit so that the recording medium is normally discharged to the paper discharge unit. If the position is set too high, the paper discharge unit interferes with the housing when the second tray is slid. Therefore, there is an upper limit on the height position of the paper discharge unit, and it cannot be raised too much.

Here, the elastic force of the spring spring 72 is generated by the holding mechanism configured by the above-described locking claw 49B provided on the rear wall 46 of the main tray 40 and the engaging piece 55 provided on the second tray 50. The spring constant is set so as to urge the second tray 50 with a force weaker than the holding force. That is, when the second tray 50 is in the first posture where it is interrupted between the paper feed roller 34 and the main tray 40, the second tray 50 is urged forward by the elastic force of the spring spring 72. Due to the engagement between the piece 55 and the locking claw 49B, the second tray 50 is held by the main tray 40 in the first posture, and the second tray 50 is not pushed back to the position of the second posture.

  In the present modification, the example in which the second support portion 67 is urged rearward by the spring spring 72 has been described. However, the spring spring is an example, and other elastic materials such as a plate spring, a torsion coil spring, and rubber are used. The structure which urges | biases the 2nd support part 67 back with a member may be sufficient. Further, a well-known lock mechanism for locking the second tray 50 to the main tray 40 may be provided in the tray body 13 instead of the locking pieces 49B and the engaging pieces 55. Further, in the present modification, the configuration in which the second support portion 67 is exposed on the surface of the first support portion 61 has been described.

The accommodating portion 63A corresponds to the accommodating portion described in the claims. Each of the second support portions 76 is pivotable by a shaft 74 between a ninth posture protruding rearward from the stepped portion 63 and a tenth posture housed in the housing portion 63A. And is regulated by a regulating member (not shown) so as to be inclined with respect to the front-rear direction 8. The length L of the second support member 76 is set to be less than half of the distance between the pair of shafts 74. That is, the pair of second support portions 76 are accommodated in the accommodation portion 63 </ b> A without overlapping each other in the front-rear direction 8. The shaft 74 is provided with an elastic member (not shown) such as a torsion coil spring that urges the second support portion 76 toward the position of the ninth posture. The upper end surface of the second support portion 76 is set substantially flush with the upper surface of the first support portion 61 so that the recording medium 24 is not caught.

  When the second tray 50 is in the second posture and an image is recorded on the first recording medium 24A placed on the main tray 40, the second support portion 76 is in the ninth posture by the elastic member, and the discharge is performed. The thus-recorded first recording medium 24A is guided to the second support portion 76 by the second support portion 76, and is stacked on the second support portion 76 and the first support portion 61. When the tray body 13 is mounted on the main body 11 in a state where the second tray 50 is changed to the first posture, the second support portion 76 rotates by hitting the housing 25, and the second support portion 76 is accommodated in the accommodating portion 63A. The posture changes to 10 postures. When the second tray 50 is returned to the second posture by the user, or when the tray body 13 is pulled out from the main body 11, the second support portion 76 returns to the ninth posture due to the elastic force of the elastic member.
