As shown in FIG. 4, the scanner unit 5 as a whole rotates upwardly about the rotation shaft 17 to open the upper portion of the apparatus main body 3, and a recording unit (such as a carriage in a liquid ejecting apparatus) The maintenance of the member corresponding to the injection unit can be performed. As shown in FIGS. 10 and 11, the scanner unit 5 is formed with two insertion portions 6. These insertion portions 6 are connected to an insertion receiving portion (not shown) formed on the apparatus body 3 side. By inserting, the scanner unit 5 can be attached to the apparatus main body 3.

  As shown in FIG. 1, the feeding unit 7 is closed by a lid 19 when not in use, and the lid 19 pivots rearward as shown in FIG. 2 around its pivot shaft 21 (FIG. 1). As a result, the feeding unit 7 is opened, and the lid 19 is fixed at a fixed angular position to function as the medium support 23. The medium support 23 is provided with an edge guide 25 that is movable according to the width dimension of the recording medium P. When the lid 19 is in an open state, a feeding port 27 is formed in the feeding unit 7, and the recording medium P stocked on the medium support 23 is fed one by one by a feeding mechanism (not shown) as shown in FIG. It is sent out from the feeding port 27 to the recording unit. The width in the front-rear direction of the feeding port 27 can be arbitrarily set, but at least the thickness of the maximum number of recording media P that can be stored on the medium support 23 is necessary. If the width in the front-rear direction of the feeding port 27 is equal to the maximum number of sheets that can be stocked with the recording medium P, the feeding port 27 is recorded in the state where the maximum number of recording media is stocked. It is closed by the medium.

A foreign matter receiving portion 61 is provided so as to close a gap formed between the front edge 29a of the foreign matter fall prevention cover 29 (details will be described later) and the rear portion of the scanner unit 5. Therefore, the foreign matter receiving part 61 together with the foreign matter fall prevention cover 29 ensures that a foreign matter such as a clip placed on the scanner unit 5 falls into the feeding port 27 when the scanner unit 5 is opened. Can be prevented.

  However, on the other hand, since the edge guide 59 is located on the rear side of the foreign material receiving portion 61, it is difficult to increase the size of the edge guide 59 (guide portion 59b). However, a concave portion is formed on the side surface of the free end of the guide portion 59b as shown in detail in FIG. Accordingly, this prevents the operability of the edge guide 59 (easy to pick the guide portion 59b) from being impaired. In particular, since the concave portion is located in the area of the hopper 57 and the base portion 59 in the sheet length direction as shown in FIG. 18, a large moment force is generated in the edge guide 59 when the edge guide 59 is operated. Therefore, it can be easily slid.

  Next, as shown in FIGS. 3, 5, 6 and 7, a foreign matter fall prevention cover 29 is provided in the feeding port 27. As shown in part of FIG. 8 and the like, the foreign matter fall prevention cover 29 has a foreign matter receiving portion 30 having a tray-like shape with a concave inside. As shown in FIG.

Thus, when the scanner unit 5 is rotated so as to be opened, the feed port 27 can be closed while the foreign matter fall prevention cover 29 moves backward as indicated by an arrow 33 in FIG.

  As shown in FIG. 8, open / close guides 35 are formed on both sides of the foreign matter fall prevention cover 29. When the foreign matter fall prevention cover 29 moves in the front-rear direction along with opening / closing of the scanner unit 5, the open / close guide 35 The free end 37 of the foreign matter fall prevention cover 29 is guided. As shown in FIG. 7, the free end 37 of the foreign matter fall prevention cover 29 is formed to be rounded in an arc shape from the rear end to the lower side, so that it can slide smoothly along the opening / closing guide 35. Yes.

  The length of the foreign matter fall prevention cover 29, that is, the position of the free end 37 is such that the maximum number of recording media P that can be placed on the feeding unit 7 when the scanner unit 5 is in the closed position as shown in FIG. When it is placed, it can be set so that it does not touch the bare top recording medium P or barely touches it. As shown in FIG. 7, when the foreign matter fall prevention cover 29 is moved in the direction of the arrow 33 as the scanner unit 5 is rotated upward, the free end 37 of the foreign matter fall prevention cover 29 is positioned at the uppermost position. After the point of contact with the recording medium P (or the medium support 23 when no recording medium exists), the free end 37 of the foreign matter drop prevention cover 29 is on the top surface of the recording medium P (the recording medium exists). Otherwise, it is guided upward while sliding on the surface of the medium support 23, and the foreign matter fall prevention cover 29 itself is gradually inclined. The foreign matter fall prevention cover 29 can be rotated to the maximum position shown in FIG. 11, but does not rotate to the position shown in FIG. 11 in an actual use state. The details of the operation of the foreign matter fall prevention cover 29 will be described later.

  Next, a structure for preventing the medium support 23 from being damaged when the scanner unit 5 is to be opened while the medium support 23 is closed will be described with reference to FIGS. 12 is a side sectional view showing the operation of the foreign matter fall prevention cover in the initial state of the scanner unit being opened, and FIG. 13 is a side sectional view showing a state where both the medium support and the scanner unit are closed. FIG. 15 is a side sectional view when the scanner unit is closed and the medium support starts to be opened, FIG. 15 is a side sectional view showing a state where the abutting action part abuts against the abutted part, and FIG. FIG. 17 is a side sectional view showing a state in which is guided to the upper surface of the protruding portion, and FIG.

  As shown in FIG. 12, a protruding portion 39 having an upper surface 40 is formed at the rear end of the scanner unit 5, and a contact action portion 41 formed in a smooth arc shape is formed above the protruding portion 39. Has been. Further, a contacted portion 43 that contacts the contact acting portion 41 when the scanner unit 5 is opened is formed below the front end of the medium support 23 (the portion that becomes the upper end when in use).

  Further, the free end 37 of the foreign matter fall prevention cover 29 is formed with a lifting action portion 47 that acts on the lower surface 45 of the medium support 23 to lift the medium support 23 upward. An inclined guide portion 49 is formed toward the lower side of the oblique front side. The opening / closing guide 35 guides the initial guide part 35a for guiding the medium support 23 at the initial stage when the scanner unit 5 is opened and the lifting action part 47 of the foreign matter fall prevention cover 29 upward, and lifts the medium support 23 upward. The ascending guide part 35b provided with the inclined surface 35c in which the front side which acts is formed diagonally. Note that the point denoted by reference numeral 51 is the rotation center when the scanner unit 5 rotates.

  Hereinafter, the operation of the foreign matter fall prevention cover 29 and the action of avoiding damage to the medium support 23 when the scanner unit 5 is to be opened while the medium support 23 is closed will be described.

  First, the foreign matter fall prevention cover 29 has a clip or other foreign matter placed on the scanner unit 5 when the medium support 23 is in an open state as shown in FIG. Is prevented from falling into the feeding port 27. When the scanner unit 5 is closed as shown in FIG. 3, the foreign matter fall prevention cover 29 is at a relatively front position. At this time, as shown in FIG. 8, the feeding port 27 is open. In FIG. 3, the recording medium P does not exist on the medium support 23, but in this example, even if the recording medium P exists on the medium support 23, the uppermost recording medium P and the foreign matter fall prevention cover It is assumed that a space is formed between the 29 free ends 37.

  As shown in FIGS. 4 and 5, when the scanner unit 5 is slightly opened, the scanner unit 5 rotates around the rotation center 51 so that the foreign matter fall prevention cover 29 advances in the direction of the arrow 33 in FIG. To come. At this time, the free end 37 of the foreign matter drop prevention cover 29 is guided by the open / close guide 35 (see FIG. 9) and freely rotates counterclockwise around the rotation shaft 31 in FIG. When the foreign matter fall prevention cover 29 moves rearward to the position shown in FIG. 5, the free end 37 of the foreign matter fall prevention cover 29 comes into contact with the uppermost recording medium P, and the feeding port 27 is closed at this point. become.

  Next, as shown in FIG. 6, when the scanner unit 5 is further opened, the foreign matter fall prevention cover 29 further moves in the direction (rearward) indicated by the arrow 33 in FIG. However, as described with reference to FIG. 5, the free end 37 of the foreign matter fall prevention cover 29 is already in contact with the uppermost recording medium P, and cannot move further in the direction of the arrow 33. However, since the free end 37 of the foreign matter fall prevention cover 29 is formed in an arcuate round shape, after the free end 37 comes into contact with the top recording medium P, the free end 37 is at the end. It is guided to the surface of the upper recording medium P and moves upward as indicated by an arrow 53 in FIG.

  At this time, since the free end 37 of the foreign matter fall prevention cover 29 remains in contact with the uppermost recording medium P, the state where the feeding port 27 is closed is maintained. Even if a foreign object such as a clip placed on the upper surface of the scanner unit 5 in this state slides down to the feeding port 27 side, the foreign object falls into the foreign object receiving portion 30, and then the foreign object fall prevention cover 29 Stay there regardless of movement. Accordingly, it is possible to prevent foreign matter from entering the inside of the apparatus main body 3 through the feeding port 27 by mistake. After the state shown in FIG. 6, the scanner unit 5 can be further rotated in the opening direction. As a result, the free end 37 of the foreign matter drop prevention cover 29 is placed on the surface of the uppermost recording medium P as described above. In the state of being guided and closing the feeding port 27, the direction of the arrow 53 is shifted. When the scanner unit 5 is closed, the foreign matter fall prevention cover 29 moves in the reverse direction during the opening operation.

  Next, the action of avoiding damage to the medium support 23 when the scanner unit 5 is to be opened while the medium support 23 is closed will be described with reference to FIGS. First, FIG. 13 shows a state where the scanner unit 5 and the medium support 23 are closed. At this time, the contact portion 41 of the protrusion 39 in the scanner unit 5 is in a state of being separated from the contacted portion 43 of the medium support 23.

  First, as shown in FIGS. 1 and 13, when both the scanner unit 5 and the medium support 23 are closed, they are in a flush state, and the entire recording apparatus has a substantially rectangular parallelepiped shape. As shown in FIG. 14, when the scanner unit 5 starts to be opened with the medium support 23 closed as shown in FIG. 14, the scanner unit 5 rotates around the rotation center 51 as described above. 29 shifts in the direction indicated by the arrow 33 in FIG. As a result, the inclined guide portion 49 at the free end 37 of the foreign matter fall prevention cover 29 is guided to the inclined surface 35c of the ascending guide portion 35b and ascends upward as indicated by an arrow 55 in FIG. Accordingly, the lifting action portion 47 at the free end 37 of the foreign matter fall prevention cover 29 comes into contact with the lower surface 45 of the medium support 23 and pushes it up (FIG. 14). As a result, the front end side of the medium support 23 slightly floats immediately before the abutting action portion 41 of the scanner unit 5 abuts against the abutted portion 43 of the medium support 23 (see FIGS. 12 and 14).

  As shown in FIG. 15, when the scanner unit 5 is further opened, the contact action portion 41 of the scanner unit 5 contacts the contacted portion 43 of the medium support 23. Thereafter, when the scanner unit 5 is further opened, the abutted portion 43 of the medium support 23 is guided to the abutting action portion 41 formed in a smooth arc shape, and the medium support 23 is slightly lifted.

  Then, as shown in FIG. 16, when the degree of opening of the scanner unit 5 increases, the contacted portion 43 of the medium support 23 is guided to the upper surface 40 of the protruding portion 39, and finally, as shown in FIG. In the position where the scanner unit 5 is opened to the maximum, the contacted portion 43 of the medium support 23 reaches the vicinity of the forefront portion of the upper surface 40 of the protruding portion 39.

In this way, at the initial stage where the scanner unit 5 starts to be opened while the medium support 23 is closed, the lifting action portion 47 formed at the free end 37 of the foreign matter fall prevention cover 29 lifts the medium support 23, and the medium support 23. As the scanner unit 5 rotates, the abutting action portion 41 of the scanner unit 5 may bite into the abutted portion 43 of the medium support 23 and damage the medium support 23. Can be avoided.
