FIG. 11 is a schematic plan view of the printing apparatus 1 of the present embodiment.
12 is a schematic plan view of the frame portion 10 of the present embodiment, and FIG. 12A shows the frame portion 10a when the tray 4 having the large support surface 8 corresponding to the large medium M is used. FIG. 12B shows the frame portion 10b when the tray 4 having the small support surface 8 corresponding to the small medium M is used.

  As can be seen by comparing FIG. 7A and FIG. 7B, the frame portion 10 of this embodiment includes a plate-like protruding portion 17 extending outward from the wall portion 12 of the pressing portion 16. For this reason, as shown in FIGS. 9 and 10, when the carriage 6 of the printing apparatus 1 is moving in the scanning direction B, such as during printing, the casing 32 provided in the conveyance path of the medium M. In this way, it is possible to effectively prevent foreign matter from entering in the intrusion direction I from the gap S between the frame portion 10 and the housing portion 32 through the opening 35. If foreign matter that has entered through the opening 35 comes into contact with the carriage 6, the image quality may be deteriorated or the carriage 6 may be damaged. The printing apparatus 1 of the present embodiment has a configuration that can reduce such a concern.

The frame portion 10 includes a pressing portion 16 that presses the medium M supported by the tray 4 and a protruding portion 17 that protrudes outward with respect to the pressing portion 16.
That is, since the printing apparatus 1 of the present embodiment includes the protruding portion 17 that protrudes outward with respect to the pressing portion 16, the protruding portion 17 causes a foreign matter from the gap S between the frame portion 10 and the housing portion 32. It is the structure which can suppress that invades.
Further, since the weight of the frame portion 10 is increased by the amount of the protruding portion 17, there is also an advantage that the medium M can be suitably pressed.
The “projecting portion 17 projecting outward with respect to the pressing portion 16” refers to a component part of the constituent member that presses the medium M from above and from the side (the pressing portion 16 in this embodiment), for example. It means a component or a component that protrudes outward (for example, laterally).

  Here, when the tray 4 is located inside the housing part 32, the protrusion 17 of the present embodiment has a gap S between the frame part 10 and the housing part 32 in a plan view having a predetermined size or less. It is configured as follows. Here, “the size is equal to or less than a predetermined value” means that the assumed foreign matter does not enter. For this reason, by setting it as such a structure, it has the structure which can suppress that the foreign material assumed from the clearance gap between the frame part 10 and the housing | casing part 32 penetrate | invades.

Further, as described above, the printing apparatus 1 of the present embodiment can mount a plurality of types having different areas of the support surface 8 that supports the medium M as the tray 4 in the printing apparatus 1. As described above, the frame portion 10 can be of a plurality of types (the frame portion 10a and the frame portion 10b) having different areas of the protrusions 17 in plan view. In other words, the frame 10 is a type corresponding to the area of the support surface 8 among a plurality of types having different areas of the protrusions 17 as viewed from the direction intersecting the support surface 8 (height direction C). Can be mounted on the tray 4.
Since the printing apparatus 1 according to the present embodiment has such a configuration, the area of the protruding portion 17 is changed according to the area of the support surface 8, so that the frame portion 10 and the housing portion 32 (inside the housing) are separated. The size of the gap S is kept below a predetermined value. This effectively suppresses the entry of foreign matter.
Note that “corresponds to the area of the support surface 8” means, for example, that the sum of the area of the support surface 8 and the area of the protrusion 17 is within a predetermined area range (that is, the area of the support surface 8 and the protrusion). And the area of 17 is inversely proportional).
Here, the frame portion 10a and the frame portion 10b of the present embodiment include a length L1a in the width direction (scanning direction B) of the frame portion 10a, a length L1b in the width direction of the frame portion 10b, and a moving direction A of the frame portion 10a. The length L2a and the length L2b in the moving direction A of the frame portion 10b are both the same.
Further, as a configuration in which a plurality of types of trays 4 and frame portions 10 can be used, not only a configuration in which two types of trays 4 and frame portions 10 can be used, but also three or more types of trays 4 and frame portions 10 can be used. It is good also as a structure.

The type of sensor Se and the configuration of the mark 33 are not particularly limited. For example, a reflective sensor can be used as the sensor Se.

  In addition, as shown in FIG. 8, the sensor Se of the present embodiment is on the opposite side (lower side) to the support surface 8 side of the protruding portion 17 in the direction intersecting the support surface 8 (height direction C). Is provided. Ink mist or the like accompanying printing tends to float on the support surface 8 side. However, by providing at least a part of the sensor Se on the side opposite to the support surface 8 side from the protruding portion 17, such ink mist is provided. It is possible to prevent the sensor Se from becoming dirty.

  Although not provided in the frame portion 10 of the present embodiment, the protruding portion 17 may be provided with a lightening portion. If the protruding portion 17 is provided with a thinned portion (a hole, a notch, or the like), the frame portion 10 can be reduced in weight, and workability when the medium M is supported on the tray 4 can be improved. .

  On the other hand, the protruding portion 17 may be provided with a weight portion. When the weight part is provided in the protrusion part 17, the frame part 10 can be comprised heavyly and the medium M can be pressed down suitably.

As shown in FIG. 12, it is rectangular in plan view, and is symmetrical in the left-right direction (scanning direction B) and symmetrical in the front-rear direction (moving direction A). For this reason, the frame part 10 of the present embodiment can be mounted on the tray 4 without worrying about the arrangement of front, rear, left and right. However, it is not limited to such a configuration. It may be asymmetrical in the front-rear direction or asymmetrical in the left-right direction, may be circular or elliptical, and a part of the protrusion 17 may have a notch or the like.

  In addition, the moving path along which the medium support unit 2 moves inside the housing portion 32 is substantially a rectangular parallelepiped. For this reason, in order to effectively reduce the size of the gap S between the frame portion 10 and the housing portion 32, the shape constituting the outer periphery of the protruding portion 17 is rectangular in plan view. However, the movement path may be configured by a curved surface or the like, and the shape constituting the outer periphery of the protruding portion 17 may be configured by a curved surface or the like accordingly.
