FIG. 1 is a perspective view of an inkjet printer 1 according to the embodiment. FIG. 2 is a cross-sectional view of the ink jet printer 1. In FIG. 2, the transport path P of the roll paper 100 is shown as a virtual line.
An ink jet printer 1 (hereinafter referred to as a printer 1) as an image recording apparatus uses a roll paper 100 in which a sheet of paper or a synthetic resin is wound in a roll shape as a recording medium, and ejects ink onto the surface of the roll paper 100. It is a printer that prints (records) images including characters by attaching them. The sheet constituting the roll paper 100 may be a sheet whose surface is coated with a synthetic resin or the like, or may be a sheet in which a label sheet having glue on the back surface is superimposed on a release sheet. In the present embodiment, a case where label paper roll paper 100 is used in the inkjet printer 1 will be described as an example.
The inkjet printer 1 records an image on the roll paper 100 and discharges the recorded roll paper 100 from a discharge port 25 provided on the front surface of the inkjet printer 1. A cutter unit 80 (FIG. 2) is provided in front of the discharge port 25, the roll paper 100 is cut to a specified length by the cutter unit 80, and the section is discharged from the discharge port 25. Therefore, the ink jet printer 1 can print out a label piece obtained by cutting the label sheet into a specified length.

  As shown in FIG. 1, the inkjet printer 1 has a substantially box-shaped main body 10. The upper surface of the main body 10 is covered with an upper surface panel 11, side panels 12 are disposed on the left and right side surfaces of the main body 10, and a rear panel 14 (FIG. 2) is disposed on the rear surface of the main body 10 perpendicular to the installation surface.

By opening the roll paper cover 20, a space for accommodating the roll paper 100 inside the ink jet printer 1 is provided. The roll paper storage unit 10a (FIG. 2) as the recording medium storage unit is exposed, and the roll paper 100 can be loaded and replaced from the front surface of the inkjet printer 1.
A discharge port 25 is opened at the upper end of the roll paper cover 20, that is, at a location corresponding to the boundary between the roll paper cover 20 and the front upper panel 13. The discharge port 25 is an elongated opening extending in the width direction of the roll paper 100, and the discharge paper guide 26 connected to the lower end of the discharge port 25 is attached to the roll paper cover 20. The discharge port paper guide 26 includes a slope that supports the roll paper 100 discharged from the discharge port 25 from below, and a pair of paper width guides 27 that are positioned at the upper end of the slope and guide the roll paper 100 from the width direction. Have The pair of paper width guides 27 are preferably in contact with both side edges of the roll paper 100. Therefore, each paper width guide 27 can be moved in accordance with the width of the roll paper 100, and a groove 28 for moving the paper width guide 27 is formed on the slope of the discharge port paper guide 26. It extends in the width direction. For this reason, a paper guide plate 29 is disposed between the pair of paper width guides 27 so as to straddle the groove 28, and the roll paper 100 is discharged on the paper guide plate 29.

  Below the discharge port paper guide 26, a discharge tray 30 (external member) that receives the roll paper 100 that has descended along the discharge port paper guide 26 is provided. The discharge tray 30 is positioned below the discharge port paper guide 26 and includes a discharge tray main body 31 that forms a receiving portion 32 that accommodates the roll paper 100, and a slide member 41 that is slidably attached to the discharge tray main body 31. And comprising. An engagement pin 35 (hinge) is provided on the upper portion of the discharge tray main body 31, and the engagement pin 35 engages with a bearing (not shown) provided on the roll paper cover 20. The discharge tray 30 is attached to the front surface of the roll paper cover 20 via an engagement pin 35 so as to be rotatable.

The receiving portion 32 of the discharge tray main body 31 is a space surrounded by a downward inclined surface, a pair of side walls 33 erected on both side ends of the inclined surface, and a paper stopper plate 42 in the same manner as the discharge opening paper guide 26. . The lower end of the slide member 41 is a paper stopper plate 42 that is positioned at the lower end of the receiving portion 32 and prevents the roll paper 100 from falling. By sliding the slide member 41 with respect to the discharge tray main body 31, the paper stopper plate 42 can be moved and the length of the receiving portion 32 can be changed.
As described above, the section of the roll paper 100 cut by the cutter unit 80 is discharged from the discharge port 25. This section descends along the slope of the discharge port paper guide 26 and falls to the receiving portion 32. Here, the section of the roll paper 100 may rotate when falling from the lower end of the inclined surface of the discharge port paper guide 26 to the receiving portion 32. When the length of the receiving portion 32 is adjusted to an appropriate length, The sections of the paper 100 are accumulated in the receiving unit 32 without being turned over. In this case, since the section of the roll paper 100 is not turned over and the surface on which the image is printed faces upward, the printed image can be visually recognized with the section accumulated in the receiving portion 32.

As shown in FIG. 2, the tip 43 a of the slide member 41 contacts the front surface of the roll paper cover 20 when the slide member 41 is slid to the main body 10 most.

That is, in the state in which the paper stopper plate 42 is located above, the angle of the paper accumulation surface 34 is reduced by the tip 43a hitting the roll paper cover 20. This state is suitable for receiving a section of the roll paper 100 cut with a short length. Since the paper stopper plate 42 is close to the discharge port 25 and the angle of the paper accumulation surface 34 is small, there is an advantage that the section of the roll paper 100 does not turn over or protrude from the receiving portion 32.
On the other hand, when the slide member 41 is pulled out downward, the leading end 43a is separated from the roll paper cover 20, and the angle of the paper accumulation surface 34 becomes steep. This state is suitable when a long section of the roll paper 100 is received because the receiving portion 32 is long. Since the paper accumulation surface 34 has a steep angle, there is an advantage that a long section is not clogged in the vicinity of the discharge port 25 and can be surely dropped to the position of the paper stopper plate 42.
Thus, the discharge tray 30 has a configuration in which the angle of the paper accumulation surface 34 is automatically changed by sliding the slide member 41 to change the length of the receiving portion 32.

That is, since it is a position deviated from directly below the hinge formed by the engagement pin 35, when a force for opening the roll paper cover 20 is further applied, the discharge tray 30 is further rotated according to this force. Accordingly, it is possible to avoid a situation in which the roll paper cover 20 is not stably opened while the discharge tray 30 is in contact with the installation surface A, and the discharge tray 30 is smoothly rotated to open the roll paper cover 20 to a sufficient opening amount. Therefore, the discharge tray 30 can be disposed without impairing the operability of the roll paper cover 20. Thereby, the restriction | limiting which concerns on the installation position of the discharge tray 30 can be avoided, and the freedom degree in design can be raised.

  The contact portion that comes into contact with the discharge tray 30 may make point contact with the installation surface A, such as the slide member 41, the contact portion 33a, and the tip 43a, or may be provided with a contact portion that makes linear contact. A surface in contact with A may be provided on the discharge tray 30.
