It will be in the state which covered the opening part 2 for feeding (FIG.1, FIG.4, FIG.7).

  On the other hand, when the cover 10 is in the second rotation position (the state in which the cover 10 is rotated in the direction indicated by B), the feeding opening 2 is opened and the first guide portion 11 of the cover 10 is opened. And the placement portion 71 constitute a series of “recording material placement surfaces” (FIGS. 2, 5, and 8). A plurality of “recording material placement surfaces” can be placed in a state where a plurality of recording papers P can be supplied from the feeding opening 2. A known edge guide 72 is disposed on the placement portion 71 so as to be slidable in the width direction of the recording paper P, and defines the placement position of the recording paper P in the width direction according to the size of the recording paper P. Can do. The recording paper P placed on the first guide 11 of the cover 10 in the opened state is pressed against the outer peripheral surface of the feeding roller 73 by a hopper (not shown), and is conveyed by driving rotation of the feeding roller 73. It is fed toward the driving roller 51. At this time, the other recording paper P is separated from the uppermost recording paper P by the known driven rotation resistance of the retard roller 74, and the double feeding of the recording paper P is prevented.

  As described above, since the feeding opening 2 is covered with the cover 10 at the first rotation position, if the cover 10 is set to the first rotation position when the inkjet printer 50 is not used, It is possible to prevent dust and foreign matter from entering from the feeding opening 2. On the other hand, at the second rotation position, the feeding opening 2 is opened, and the first cover 11 of the cover 10 at the second rotation position is moved from the feeding opening 2 to “ A “recording material placement surface” on which the recording paper P to be supplied to the “automatic feeding device” can be placed.

That is, the cover 10 according to the present invention functions as a protective cover for the ink jet printer 50 at the first rotation position, and as the “recording material placement surface” of the “automatic feeding device” at the second rotation position. Since it functions, it is not necessary to separately provide a dedicated feeding tray or the like in the inkjet printer 50. Therefore, the number of parts of the ink jet printer 50 can be reduced and the cost can be reduced. In addition, since the cover 10 according to the present invention covers the part of the ink jet printer 50 by being in the second rotation position and becomes a protective cover, the appearance is made compact while protecting the ink jet printer 50 when not in use. can do.
In addition, it is configured so that the recording paper P discharge port is covered with the closed cover 10 without providing the paper discharge tray 3, and dust, foreign matter, etc. enter the recording paper P from the discharge port. You may not make it.

  The cover 10 according to the present invention includes a first cover portion 11 and an upper cover 12 and a recording surface cover portion 13 that constitute a “second cover portion”. One end of the first cover 11 is rotatably supported by the printer main body 1 with a rotation shaft 14 and constitutes a “recording material placement surface” as described above at the second rotation position. One end side of the upper cover portion 12 is rotatably connected to the other end side of the first cover portion 11 by a rotating shaft 15, and the recording surface cover portion 13 is connected to the other end side of the upper cover 12 with a rotating shaft 16. It is connected so that it can rotate.

  At the first rotation position, as shown in the figure, the connecting portion (the portion of the rotation shaft 16) between the upper cover portion 12 and the recording surface cover portion 13 is located at the boundary portion between the upper surface and the front surface of the printer body 1. As described above, the upper surface (the operation panel 4 and the feeding opening 2) and the front surface (the paper discharge tray 3) of the printer main body 1 are covered with the cover 10 (FIGS. 1, 4, and 7). With such a connection structure, the cover 10 can be covered from the upper surface to the front surface of the printer body 1 while being bent along the outer shape of the printer body 1 in a closed state. Therefore, the cover 10 in the closed state can protect the printer main body 1 in a state where the upper surface and the front surface of the printer main body 1 are covered along the outer shape, thereby preventing the aesthetic appearance of the inkjet printer 50 from being damaged. be able to. It should be noted that the cover 10 is closed when the first cover portion 11 and the upper cover portion 12 (second cover portion) are connected to each other (the portion of the rotation shaft 15) is the upper surface and the front surface of the printer body 1. It may be located at the boundary between

  Further, on the other end side of the recording surface cover portion 13 (second cover portion), a magnet 17 is built in a portion that comes into contact with the printer main body 1 at the first rotation position. Therefore, when the cover 10 is closed, the magnetic surface is adsorbed between the magnet 17 and a metal frame (not shown) constituting the ink jet printer 50 at the portion where the recording surface cover 13 and the printer main body 1 abut. Force acts. As a result, when the cover 10 is closed, the contact state of the recording surface cover 13 with the printer main body 1 is maintained, so that the first rotational position of the cover 10 can be reliably held (FIG. 1). 4 and 7).

  FIG. 3 is a side sectional view of a main part of an ink jet printer 50 as an example of a “recording apparatus” according to the present invention. FIGS. 6 and 9 are external perspective views of the ink jet printer 50 according to the present invention. FIG. 9 illustrates a state in which the recording paper P placed on the first cover portion 11 is covered with a part of the cover 10 in the second rotation position.

  In the cover 10 according to the present invention, the upper cover portion 12 and the recording surface cover portion 13 are denoted by reference character C as shown in the drawing, assuming that the rotation position of the first cover portion 11 with respect to the printer body 1 remains the same in the second rotation position. It can be rotated in the direction indicated by. At that time, the front end (the other end side) of the recording surface cover portion 13 rotated in the direction indicated by the reference symbol C is brought into contact with a locking portion 5 provided in the vicinity of the feeding opening 2 to be locked. It will be in the state. As a result, the recording paper P placed on the first cover portion 11 is covered with the upper cover portion 12 and the recording surface cover portion 13 (FIGS. 3, 6, and 9). Accordingly, the recording paper P placed on the first cover portion 11 is in a state in which automatic feeding by the driving rotation of the feeding roller 73 is possible, and the upper end (side end on the upstream side in the feeding direction) is the upper cover. The recording surface of the uppermost recording paper P covered with the portion 12 is covered with the recording surface cover portion 13.

  As described above, the cover 10 according to the present invention is in the uppermost position while the recording paper P placed on the first cover portion 11 can be automatically fed by the driving rotation of the feeding roller 73. The recording surface of the recording paper P can be covered with the recording surface cover 13. As a result, the recording surface of the recording paper P at the top of the recording paper P placed on the first cover portion 11 can be protected from dust, ultraviolet rays, and the like. Therefore, when the user leaves the recording paper P placed on the first cover portion 11 without taking it out, the user can leave the recording paper P for a long time in a state where it can be executed at any time. It is possible to reduce the possibility that the recording paper P placed on the sheet will be altered, discolored, curled (warped), or the like.

  Further, the cover 10 according to the present invention can only cover the recording surface of the recording paper P on the top with respect to the recording paper P placed on the first cover portion 11 with the recording surface cover portion 13. In addition, the upper cover 12 can also cover the upper end (the side end on the upstream side in the feeding direction). Accordingly, since the portion where the recording paper P placed on the first cover portion 11 is exposed to the outside can be reduced, the protection effect of the recording paper P can be further improved.

  The upper cover portion 12 and the recording surface cover portion 13 (second cover portion) are in a state in which the recording paper P placed on the first cover portion 11 can be automatically fed by the driving rotation of the feeding roller 73. As it is, they are connected so as to be able to take a rotation position that covers the recording paper P and a rotation position that does not cover the recording paper P. Accordingly, when the user places the recording paper P on the first cover portion 11 of the cover 10 in the second rotation position or takes out the recording paper P placed on the first cover portion 11, 1 Rotate the upper cover part 12 and the recording surface cover part 13 (second cover part) to a rotational position that does not cover the recording paper P placed on the cover part 11 (rotate in the direction indicated by reference numeral B). It is possible to easily perform these operations (FIGS. 2, 5, and 8).

  Further, in a state where the recording paper P placed on the first cover portion 11 is covered with the recording surface cover portion 13 (the state illustrated in FIGS. 3, 6, and 9), the recording surface cover portion 13 is caused by its own weight. The recording value P placed on the first cover portion 11 is pressed from the uppermost side to the first cover portion 11 and is sandwiched between the recording surface cover portion 13 and the first cover portion 11. Thereby, the placement position of the recording paper P placed on the first cover portion 11 is held by the pressing force due to the weight of the recording surface cover portion 13. In addition, the recording paper P placed on the first cover portion 11 is sandwiched between the recording surface cover portion 13 and the first cover portion 11, so that the leading edge of the recording paper P against the abutment surface of the placement portion 71. The applied load is reduced. Therefore, it is possible to reduce the possibility of curling so that the leading edge of the recording paper P placed on the first cover portion 11 is pushed and bent.

  The pressing force due to the weight of the recording surface cover portion 13 also acts as a correction force against the warp of the recording paper P caused by the surrounding temperature change, humidity, etc., so that it is placed on the first cover portion 11. It is possible to reduce the possibility of warping of the recording paper P. Furthermore, since the weight of the recording surface cover portion 13 is increased by the magnet 17 built in the other end of the recording surface cover portion 13, the recording paper P placed on the first cover portion 11 with a stronger pressing force can be removed. 1 cover 11 can be pressed.

  Further, in a state where the recording surface cover portion 13 covers the recording value P placed on the first cover portion 11, according to the change in the quantity of the recording paper P placed on the first cover portion, It is displaced so as to always be in contact with the recording surface of the uppermost recording paper P. More specifically, the recording surface cover 13 is placed with its own weight in contact with the recording surface of the recording paper P at the top of the recording value P placed on the first cover portion 11. The recording surface cover portion 13 is displaced while the upper cover portion 12 and the recording surface cover portion 13 are rotated in accordance with an increase or decrease in the number of recording papers P that are present. Accordingly, the recording paper P placed on the first cover portion 11 can be reliably protected from dust, ultraviolet rays, etc. regardless of the quantity of the recording paper P placed on the first cover portion 11.

  Further, the recording surface cover portion 13 is engaged with the edge guide 72 and holds the sliding position of the edge guide 72 as shown in the drawing while covering the recording value P placed on the first cover portion 11. Two groove portions 131 as “edge guide holding portions” are provided. That is, in a state where the recording value P placed on the first cover portion 11 is covered, the slide position of the edge guide 72 is held by the groove portion 131. Accordingly, it is possible to prevent the slide position of the edge guide 72 from being shifted due to vibration or the like when moving the inkjet printer 50. Therefore, the regulation of the placement position of the recording paper P by the edge guide 72 is always performed. It can be maintained in an appropriate state. Therefore, it is possible to prevent a decrease in recording accuracy due to a shift of the placement position of the recording paper P in the first cover portion 11 from an appropriate position.

  Furthermore, in the cover 10 according to the present invention, the recording paper placed on the first cover portion 11 in any one of the first cover portion 11, the upper cover portion 12, or the recording surface cover portion 13 (second cover portion). You may provide the side cover part (not shown) which covers the both ends of the width direction X of P (direction which cross | intersects a feeding direction). As a result, both side edges in the width direction X of the recording paper P placed on the first cover portion 11 can be protected, so that the recording paper P placed on the first cover portion 11 is protected from dust, ultraviolet rays, and the like. Furthermore, it can protect reliably.

  As described above, according to the cover 10 according to the present invention, the opened cover 10 constitutes the placement surface of the recording paper P to be supplied to the “automatic feeding device” and the user can record the recording paper P. When the recording paper P is left without being taken out from the placement surface of the recording paper P and left on the recording paper P for a long time in a state where it can be executed at any time, the recording placed on the placement surface of the recording paper P A “recording apparatus” such as the ink jet printer 50 can be realized which is less likely to cause alteration, discoloration, curling (warping), or the like of the paper P.

  Next, a second embodiment of the cover 10 according to the present invention will be described with reference to FIGS.

FIG. 10 is a side sectional view of an essential part illustrating an ink jet printer 50 according to the present invention, and FIG. 11 is an external perspective view thereof, both of which are a part of the cover 10 in the second rotation position. 1 illustrates a state in which the recording paper P placed on the cover portion 11 is covered.
In the cover 10 in the second embodiment, the uppermost recording paper P covers the recording surface of the uppermost recording paper P placed on the “recording material placement surface”. A friction reducing roller 18 as a “friction reducing portion” is disposed at a portion that comes into sliding contact with the “automatic feeding device”. More specifically, the friction reduction roller 18 is disposed in the vicinity of the tip of the recording surface cover portion 13 constituting the cover 10 as shown in the figure, and is rotatably supported by the recording surface cover portion 13. Other configurations are the same as those of the first embodiment illustrated and described with reference to FIGS.

  When the uppermost recording paper P is fed by the “automatic feeding device”, the friction reduction roller 18 is in contact with the recording paper P in the feeding direction (conveying direction) of the recording paper P. Rotate following the movement in the same direction as Y). As a result, it is possible to reduce the possibility that the recording paper P is scratched at the portion where the fed recording paper P and the vicinity of the tip of the recording surface cover portion 13 are in sliding contact. Further, when recording is performed on the fed recording paper P, the back tension generated when the recording paper P is transported in the transport direction Y by a predetermined transport amount can be reduced. Accordingly, it is possible to reduce a decrease in recording accuracy due to a conveyance error due to the back tension.

  The “friction reducing portion” is not particularly limited to the friction reducing roller 18, and can reduce the frictional resistance of the portion where the recording paper P to be fed and the recording surface cover portion 13 are in sliding contact. Needless to say, the effect can be obtained in any mode. For example, the “friction reduction unit” may be configured by applying so-called mirror finishing / mirror finishing to the entire surface or a part of the surface of the recording surface cover 13 that is in contact with the recording paper P.

  Further, in the ink jet printer 50, the friction reduction roller 18 is preferably disposed at a position corresponding to a substantially central position in the width direction X of the recording paper P as shown in the drawing. This arrangement position substantially coincides with the arrangement position of the feeding roller 73 in the width direction X. Therefore, it is caused by the direction of the rotational force of the feeding roller 73 acting on the fed recording paper P and the slight load acting on the engaging portion between the fed recording paper P and the friction reducing roller 18. The direction of the pulling force generated in this manner substantially coincides on the same line parallel to the feeding direction. Accordingly, the recording paper P is skewed (recording paper with respect to the feeding direction) due to a slight load acting on the engaging portion between the recording paper P fed by the rotation of the feeding roller 73 and the friction reduction roller 18. It is possible to further reduce the possibility of occurrence of (inclination of P).

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
