The ink ejected from the line head 44 is supplied from each ink storage unit to the line head 44 through a tube whose illustration is omitted. The ink storage units 10A, 10B, 10C, and 10D are detachably provided to mounting units 11A, 11B, 11C, and 11D.
In addition, the reference symbol 12 represents a waste liquid storage unit that stores ink as waste liquid that has been ejected for maintenance from the line head 44 toward a flushing cap not illustrated in the drawing.
The conveyance belt 13 is an endless belt provided around a pulley 14 and a pulley 15, and rotates when at least one of the pulley 14 and the pulley 15 is driven by a motor not illustrated in the drawing. The medium is attracted on the belt surface of the conveyance belt 13 and conveyed at a position facing the line head 44. Publicly known attraction systems such as an air suction system and an electrostatic attraction system may be employed for the attraction of the medium to the conveyance belt 13.
In this case, the recording conveyance path T1 passing through the position facing the line head 44 intersects both the horizontal direction and vertical direction, and conveys the medium upward. Specifically, the F-axis direction intersects both the horizontal direction and vertical direction. An ejecting surface 44a for ejecting the ink in the line head 44 is also parallel to the F-axis direction and intersects both the horizontal direction and vertical direction. In this embodiment, an angle α of the F-axis direction with respect to the horizontal direction is 75°. Note that the angle α may be changed to other angles as necessary within a range of 0°<α≤90°. For example, the angle a may be set within a range of 45°≤α≤80°. Note that in the case where the device body 2 is downsized, 60°≤α≤80° is preferable.
The medium on which the recording has been performed on the first surface by the line head 44 is further sent upward by the conveyance roller pair 32 located downstream of the conveyance belt 13.
A flap 41 is provided on the downstream side of the conveyance roller pair 32, and the flap 41 switches the conveyance direction of the medium. In the case where the medium is ejected as it is, the conveyance path of the medium is switched by the flap 41 toward a conveyance roller pair 35 on the upper side, and the medium is ejected by the conveyance roller pair 35 toward an ejection tray 8 that is an example of a medium placing part.
In the case where the recording is performed on the second surface of the medium in addition to the first surface, the conveyance direction of the medium is directed toward a flap 42 by the flap 41. Normally, the flap 42 lies in the counterclockwise direction in
The switchback path T2 is coupled with a connection path T3. In this embodiment, the connection path T3 is the conveyance path of the medium from the position of the flap 42 to a conveyance roller pair 34. In addition, the connection path T3 is coupled with a reverse path T4. In this embodiment, the reverse path T4 is the conveyance path of the medium from the conveyance roller pair 34 to the conveyance roller pair 31 through a conveyance roller pair 38. The reverse path T4 is a conveyance path located immediately below the line head 44 on the upstream side of the position facing the line head 44.
The medium conveyed downward from the position of the flap 42 receives a sending force from the conveyance roller pairs 33 and 34 to reach the conveyance roller pair 38, and then reversed in a curved form and sent to the conveyance roller pair 31.
The medium sent to the position facing the line head 44 again faces the line head 44 at the second surface on the opposite side of the first surface on which the recording has been performed. In this manner, the recording with the line head 44 on the second surface of the medium can be achieved.

In addition, as illustrated in
In the above-described manner, the holding member 75 can hold the second open state of the support tray 17.
As described above, the opening/closing member holding device 50 includes the body part 61 and the cover 65. The cover 65 is set to an attached state where it covers at least a part of the body part 61 when the fixing screw 66 that is an example of a fastening part is fastened to the body part 61, and the cover 65 can be detached from the body part 61 when the fixing screw 66 is detached. In addition, the opening/closing member holding device 50 includes the support tray 17 that is switchable to the closed state where the fixing screw 66 fastened to the body part 61 is covered, and the first open state where the fixing screw 66 fastened to the body part 61 is exposed, and the holding member 75 that is attachable to and detachable from the body part 61. The holding member 75 can hold the support tray 17 in the second open state that is further opened than in the first open state of the support tray 17.
With the support tray 17 set to the second open state, the maintenance work on the upper side of the support tray 17 can be easily performed.
Further, since the holding member 75 is attachable to and detachable from the body part 61, it is not necessary to provide a mechanism for holding the support tray 17 in the second open state around the support tray 17, and thus the upsizing of the device can be suppressed. Note that since the holding member 75 can be disposed at an appropriate position of the body part 61, the degree of freedom in the arrangement of the holding member 75 can be achieved, and thus it is possible to suppress the upsizing of the body part 61 in the case where the holding member 75 is provided at the body part 61.
In addition, the holding member 75 is a wire-shaped member that includes the first engaging portion 75a that is engageable with the support tray 17 on the one end el side, and the second engaging portion 75b that is engageable with the body part 61 on the other end e2 side.
In this manner, the space for disposing the holding member 75 at the body part 61 can be saved, and thus the upsizing of the body part 61 can be suppressed.
In addition, when the cover 65 is in the attached state, the holding member 75 restricts the movement of the cover 65 in the detaching direction of the cover 65. In this manner, the following operational effects can be achieved.
The cover 65 is attached to the body part 61 with the fixing screw 66, but the portion of the cover 65 that is not fastened with the fixing screw 66 may be deflected in the direction away from the body part 61. Such a deflection of the cover 65 may form a gap between the body part 61 and the cover 65, and dust and the like may enter the body part 61, thus impairing the function of the body part 61.
However, since the holding member 75 restricts the movement of the cover 65 in the detaching direction of the cover 65 when the cover 65 is in the attached state, the deflection of the cover 65 can be suppressed, and entry of dust and the like into the body part 61 can be suppressed. Note that since the holding member 57 suppresses the deflection of the cover 65 in the above-described manner, it is preferable that the position where the deflection is suppressed is the center of the cover 65 in the Z-axis direction.
In addition, since the holding member 75 can not only hold the support tray 17 in the second open state, but also suppress the deflection of the cover 65 in the above-described manner, the holding member 75 can be effectively utilized.
In addition, the cover 65 includes the protruding portion 65b protruding to the body part 61 side, and the flange portion 77a located at the tip of the protruding portion 65b. The body part 61 includes the first opening 61a for exposing the tip of the protruding portion 65b, and the second engaging portion 75b of the holding member 75 enters the portion between the flange portion 77a and the body part 61 such that the holding member 75 restricts the movement of the cover 65 in the detaching direction of the cover 65. In this manner, the configuration in which the holding member 75 restricts the movement of the cover 65 in the detaching direction of the cover 65 can be easily achieved.
Note that while the second engaging portion 75b of the holding member 75 enters the portion between the flange portion 77a and the body part 61 in this embodiment, the first engaging portion 75a of the holding member 75 may enter the portion between the flange portion 77a and the body part 61.
In addition, the body part 61 includes the second opening 61b, and the first engaging portion 75a of the holding member 75 can enter the second opening 61b. In this manner, the following operational effects can be achieved.
If the first engaging portion 75a is in a free state with the second engaging portion 75b of the holding member 75 inside the portion between the flange portion 77a and the body part 61, the holding member 75 easily drops off. However, since the first engaging portion 75a of the holding member 75 can enter the second opening 61b, the holding member 75 does not easily drop off from the body part 61.
In addition, the both ends of the wire-shaped member making up the holding member 75 are bent as illustrated in
In addition, the door unit 60, i.e., the body part 61 is provided at the side surface of the device body 2 such that it can be opened and closed. The device body 2 includes the first medium cassette 3 that is the medium storage unit that can store the medium, and when the side surface where the first medium cassette 3 is provided in the device body 2 is set as the front surface of the device body 2, the door unit 60, i.e., the body part 61 is provided at the right side surface of the device body 2.
Further, the holding member 75 restricts the movement of the cover 65 in the detaching direction of the cover 65 on the device front surface side of the cover 65 with the door unit 60, i.e., the body part 61 in the closed state.
In the configuration in which the body part 61 is provided at the right side surface or left side surface of the device body 2, when the cover 65 deflects in the direction away from the body part 61, the deflection is easily visually recognized from the user side facing straight the device body 2, and dust and the like easily enter from the gap between the body part 61 and the cover 65.
However, since the holding member 75 restricts the movement of the cover 65 in the detaching direction of the cover 65 on the device front surface side of the cover 65 as described above, the deflection of the cover 65 can be prevented from being easily visually recognized from the user side, and the dust and the like can be prevented from easily entering from the gap between the body part 61 and the cover 65.
Note that while the door unit 60, i.e., the body part 61 is provided at the right side surface of the device body 2 in this embodiment, it may be provided on the left side surface.
In addition, since the opening/closing member holding device 50 includes the supplying roller 19 that supplies the medium from the support tray 17, and the rotation shaft 18 of the supplying roller 19, and the second engaging portion 75b is engageable with the rotation shaft 18 of the supplying roller 19, it is not necessary to separately provide the portion where the second engaging portion 75b is engaged, and thus the increase in device cost can be suppressed.
In addition, the groove 18a is formed in the rotation shaft 18, and the hook 19d that is engageable with the groove 18a is provided in the supplying roller 19, and, the second engaging portion 75b is engageable with the groove 18a. When the hook 19d provided in the supplying roller 19 as described above engages with the groove 18a provided in the rotation shaft 18, the supplying roller 19 can be positioned at the rotation shaft 18. Further, since the second engaging portion 75b of the holding member 75 is engageable with the groove 18a, it is not necessary to separately form the portion where the second engaging portion 75b is engaged, and thus the increase in device cost can be suppressed, while allowing the second engaging portion 75b to reliably engage with the rotation shaft 18.
In addition, a plurality of medium detection units, or more specifically the first medium detection unit 80 and the second medium detection unit 85, for detecting the medium is provided in the conveyance path of the medium in the medium conveyance device 100. Further, since the plurality of medium detection units is accessible when the cover 65 is detached from the body part 61, the maintenance of the plurality of medium detection units can be easily performed.
It goes without saying that the present invention is not limited to the embodiments and variations described above, and various variations are possible within the scope of the invention described in the claims, which are also within the scope of the invention.
For example, while the opening/closing member held in the second open state by the holding member 75 is the support tray 17 for supplying the medium in the above-mentioned embodiment, but it may be other opening/closing members, such as a sheet tray.
In addition, while the second engaging portion 75b of the holding member 75 engages with the rotation shaft 18 of the supplying roller 19 in this embodiment, it may naturally engage with other portions.
In addition, while one holding member 75 is provided in this embodiment, a plurality of holding members 75 may be provided.
