(43) As illustrated in
(44) Here, the term “being in contact with the two faces with different orientations” denotes the term “being in contact with at least two faces”, and may denote the term “being in contact with three or more faces”.
(45) As described above, the medium supporting unit 2 according to the example is configured to be movable within a movable range, and the movable range includes the set position for a medium to be set. As illustrated in
(46) The printing apparatus 1 according to the example is configured to use one of a plurality of trays 4 with different sizes in accordance with a size of a medium to be used. The printing apparatus 1 is configured to use a plurality of frames 10 with different sizes (the frame 10a, the frame 10b, the frame 10c, and the frame 10d) in accordance with the plurality of trays 4 with different sizes. The plurality of frames 10 each have rectangular shapes each having two longer sides and two shorter sides. At this time, the printing apparatus 1 is configured to use one type of tray 4 and frame 10 at a time, and configured to allow a user to select and use one of the plurality of trays 4 with different sizes and one of the plurality of frames 10 with different sizes. That is, the printing apparatus 1 is configured to allow a tray 4 to be replaced with another tray 4 of the plurality of trays 4 with different sizes, and configured to allow a frame 10 to be replaced with another frame 10 of the plurality of frames 10 with different sizes.
(47) As illustrated in
(48) As described above, the printing apparatus 1 according to the example includes the plurality of retainers 13, and is configured to allow the plurality of retainers 13 to particularly securely retain the frame 10 (see
(49)
(50) As described above, depending on a size of the frame 10, there is a case where the plurality of retainers 13 are used to retain the frame 10, or a case where one of the plurality of retainers 13 is used to retain the frame 10. Which part of the frame 10 is to be placed on the retainer 13 differs depending on a size of the frame 10. In any cases, the frame 10 may be retained by the retainer 13 in a posture that allows the frame 10 to be stably retained.
(51) As illustrated in
(52) The retainer 13 is also detachable from the housing unit 16. When the retainer 13 is detached from the housing unit 16, the retainer 13 is moved (rotated) relative to the housing unit 16 in a direction D, and is pulled out upward, as illustrated in
(53) As described above, the retainer 13 according to the example is configured to be detachable from the printing apparatus 1. The printing apparatus 1 according to the example allows the retainer 13 to be easily detached when the retainer 13 is not to be used or is to be replaced, for example (see
(54) The configuration of the retainer 13 and the configuration of the attachment section 12 at which the retainers 13 are attached are not limited to the above described configurations. For example, such a configuration may be applied that is different from a configuration where the retainer 13 is rotated relative to the housing unit 16 for attachment and detachment. Such a configuration may also be applied that the retainer 13 is configured not to be easily detached from the housing unit 16. The retainer 13 and the attachment section 12 at which the retainer 13 is attached are not limited to the configurations in shape, raw material, size, and the like, described in the above example.
(55) However, in a configuration where the retainer 13 is freely detachable from the housing unit 16 in any state, the retainer 13 may unexpectedly be detached from the housing unit 16, and, a loss of the retainer 13 and the like may occur. In the printing apparatus 1 according to the example, when the medium supporting unit 2 is positioned at the set position, the retainer 13 is attached at a position allowing the medium supporting unit 2 to prevent the retainer 13 from being detached from the printing apparatus 1. Specifically, as illustrated in
(56) Other configuration examples may include, in which the retainer 13 is attached at a position, at which that allows the medium supporting unit 2 to prevent the retainer 13 from being detached from the printing apparatus 1, a configuration example where the retainer 13 may be fixed to the printing apparatus 1 with a pin, a screw, or the like, and the medium supporting unit 2 positioned at the set position may prevent the pin, the screw, or the like from being accessed. Specifically, it is a configuration, in which the pin or the screw is covered by the medium receiving unit 15 and the like when the medium supporting unit 2 is positioned at the set position. However, the above described configuration is not intended to result in limitation.
(57) In the printing apparatus 1 according to the example, an attaching position for the retainer 13 on the printing apparatus 1 is predetermined. However, the above described configuration is not intended to result in limitation. The printing apparatus 1 may be configured to allow the attaching position for the retainer 13 on the printing apparatus 1 to be adjusted.
(58) An example of the printing apparatus 1 configured to allow the attaching position for the retainer 13 to be adjusted in relation to the printing apparatus 1 will now be described herein.

(61) As illustrated in
(62) In other words, in the printing apparatus 1 according to the example, the spacing between the two retainers 13 is adjustable. In a configuration where a tray 4 is replaceable with another tray 4 of a plurality of trays 4 with different sizes and a frame 10 is replaceable with another frame 10 of a plurality of frames 10 with different sizes, the printing apparatus is allowed to support the plurality of frames 10 with different sizes by adjusting the spacing between the two retainers 13. Specifically, for example, the printing apparatus 1 allows the two retainers 13 to have a narrower spacing between the two retainers 13 to securely retain a smaller frame, such as the frame 10c and the frame 10d, as respectively illustrated in
Example 3
FIG. 18
(63)
(64) The printing apparatus 1 according to Example 3 is configured in a similar manner to the printing apparatuses 1 according to Examples 1 and 2, excluding a configuration of the attachment section 12 (instead of the round hole 17, a groove 18 is formed along a scanning direction B).
(65) As illustrated in
(66) In other words, the printing apparatus 1 according to the example is also configured to adjust the spacing between the two retainers 13, similar to the printing apparatus 1 according to Example 2. In a configuration where a tray 4 is replaceable with another tray 4 of a plurality of trays 4 with different sizes and a frame 10 is replaceable with another frame 10 of a plurality of frames 10 with different sizes, the printing apparatus 1 is allowed to support the plurality of frames 10 with different sizes by adjusting the spacing between the two retainers 13. Specifically, for example, the printing apparatus 1 allows the two retainers 13 to have a narrower spacing between the two retainers 13 to securely retain a smaller frame, such as the frame 10c and the frame 10d, as respectively illustrated in
(67) The printing apparatuses 1 according Examples 1 to 3, as described above, are configured to allow the plurality of retainers 13 to be attached to the end portion on the side of the set position of each of the printing apparatuses 1 in the movement direction A of the medium supporting unit 2. However, the above described configuration example is not intended to result in limitation. In still another configuration, the plurality of retainers 13 may be attached at different attaching positions on the printing apparatuses 1.
(68) An example where attaching positions for a plurality of retainers 13 on a printing apparatus 1 differ from the attaching positions on the printing apparatuses 1 according to Examples 1 to 3 as described above will now be described herein.
