Description

  The present invention relates to an ink jet printer apparatus and a printer apparatus, and more particularly to an ink jet printer apparatus and a printer apparatus provided with a tray for receiving printed and discharged paper.

  In a printer apparatus represented by an ink jet printer apparatus or the like, a predetermined tray is provided for receiving paper that is printed or printed and discharged. The paper is forcibly ejected from the printer device and placed on the tray. At this time, the paper may fall from the leading edge of the tray due to the momentum of the discharged paper. Therefore, for example, as shown in FIG. 13, there is a tray 103 of the printer apparatus 101 in which a stand 105 is provided on the front end side of the tray 103 in order to prevent this.

  However, in the tray 103 provided with the upright 105, in a state where the tray 103 is not pulled out to a predetermined position (tray 103a), the leading end side of the paper 150 hits the upright 105a, and the paper is displaced from the discharge direction. There is. If the sheet 150 is displaced in the discharge direction, the printing position on the sheet 150 is displaced.

  In particular, when the position of the paper 150 is shifted in the ink jet printer apparatus, there is a problem that the color is shifted. However, in order to solve this problem, if the length of the paper 150 in the discharge direction in the tray is made longer, the casing of the printer device becomes larger and the packing material for packing it becomes larger, for example, the transportation cost increases. A new problem will arise.

  Therefore, as an example of a tray for solving such a problem, for example, Patent Document 1 proposes a tray 107 that extends stepwise in the paper discharge direction as shown in FIG. The tray 107 includes a fixed tray 107a, a movable tray 107b, a sub holder 107c, and a stopper 107d. Similarly, Patent Document 2 proposes a tray extending stepwise.

Further, for example, in Patent Document 3, as shown in FIG. 15, a tray 109 is proposed in which the front end side (paper discharge direction destination) is lifted and inclined. The tray 109 includes a stacker base portion 109a, a first drawer portion 109b, and a second drawer portion 109c. By applying a predetermined elastic force 111 to the rear end portion of the stacker base portion 109a, the front end side of the tray 109 is lifted. Yes.

  An ink jet printer apparatus according to an embodiment of the present invention will be described. As shown in FIG. 1, in the inkjet printer apparatus 1, a printer main body 2 for printing or printing on a predetermined paper (not shown), and a paper discharged from the printer main body 2 in a predetermined direction. A tray 4 for receiving from below is provided. The tray 4 is accommodated in a tray accommodating portion 3 provided below the printer main body 2 as shown in FIG. 1 when the ink jet printer apparatus 1 is not in operation.

  On the other hand, when the ink jet printer apparatus 1 is operated, the tray 4 is pulled out in the direction in which the paper is discharged (arrow 30), as shown in FIG. At this time, as shown in FIG. 3, the front side of the tray 4 is lifted with respect to the rear side and is inclined. The paper printed in this state is discharged onto the tray 4.

  Next, the tray 4 will be described. As shown in FIG. 4, the tray 4 has a flat plate portion 4a on which paper is placed. As shown in FIG. 5, in the flat plate portion 4a, the peripheral wall portion 5 is formed along the outer edge on the surface (back surface) opposite to the side on which the paper is placed (front surface). The peripheral wall portion 5 is provided with a portion 5a having a lower height than other portions on the rear end side.

  Furthermore, rail ribs 6 are formed on the rear end side of the surface of the flat plate portion 4a along the direction in which the tray 4 is pulled out (arrow 30). The rail rib 6 is formed so that its height gradually increases from the front to the rear. The tray 4 is a single molded body, and is formed, for example, by molding a resin or the like.

  Next, the main part of the tray storage unit 3 for storing the tray 4 will be described. As shown in FIG. 6, the peripheral wall portion 5 of the tray 4 contacts the tray storage portion 3, and the paper is discharged between the state in which the tray 4 is stored and the state in which the tray 4 is pulled out. Side wall portions 3a (one not shown) are formed so as to oppose each other to allow movement of the tray 4.

  The rail rib 6 of the tray 4 is inserted into the side wall 3a from below to guide the movement of the tray 4, and as will be described later, it is inserted to lift the front end side of the tray 4 upward when the tray 4 is pulled out. A guide rib 7 having portions 7a and 7b is provided.

  Further, behind the guide rib 7, the tray 4 is pulled out, and the rear end portion of the tray 4 is lifted as the sheet is discharged onto the tray 4. A presser portion 8 is provided for blocking and blocking. Further, a support portion 9 is provided behind the presser portion 8 to hold the state in which the front end side of the tray 4 is lifted up with the tray 4 being pulled out. The ink jet printer apparatus according to this embodiment is configured as described above.

  Next, the operation of the above-described ink jet printer apparatus 1 will be described. First, as shown in FIG. 7, when the ink jet printer apparatus is not operated, the tray 4 is stored in the tray storage unit 3. Next, when the ink jet printer apparatus is operated, the tray 4 is pulled out from the tray storage unit 3. As the tray 4 is pulled out, the rail rib 6 provided on the tray 4 is supported from below by the guide rib 7 provided on the tray storage unit 3.

  At this time, the guide rib 7 reaches a predetermined position on the rail rib 6 while the front end side of the tray 4 is gradually lifted by the guide rib 6 inclined so as to gradually increase in height from the front to the rear. Tray 4 will be pulled out. In this way, as shown in FIGS. 8 and 9, the front end side of the tray 4 is lifted up with the tray 4 fully pulled out.

  This state is held by the guide rib 7, the presser portion 8, and the support portion 9. This will be described. As shown in FIG. 10, first, the front end side of the tray 4 is lifted upward by the guide rib 7 and the rail rib 6. On the other hand, as the paper is discharged onto the tray 4, the portion of the tray 4 positioned in front of the guide rib 7 is lowered downward (arrow 31) with the contact portion P 1 between the rail rib 6 and the guide rib 7 as a fulcrum. By trying to do so, the portion of the tray 4 located behind the guide rib 7 tends to be lifted upward (arrow 32). At this time, by pressing the tray 4 from above by the presser portion 8, it is possible to prevent the portion of the tray 4 positioned behind the guide rib 7 from being lifted.

  In addition, when the tray 4 is pulled out, the lower portion 5a of the peripheral wall portion 5 is supported by the support portion 9 from below so that the tray 4 rattles in the direction opposite to the arrow 32. Be blocked. As described above, in the tray 4, the guide rib 7 and the support portion 9 that are disposed at a distance on the back surface side thereof are in contact with each other at the contact portions P <b> 1 and P <b> 3. On the other hand, on the surface side, the presser portion 8 disposed between the guide rib 7 and the support portion 9 contacts at the contact portion P2. Thus, in this ink jet printer apparatus, the state where the front end portion of the tray 4 is lifted is held.

  As described above, in this inkjet printer apparatus, by pulling out the tray 4, the rail rib 6 provided in the tray 4 and the guide rib 7 provided in the tray storage unit 3 are in a state where the front end portion is lifted, This state is held by the presser portion 8 including the guide rib 7 and the support portion 9.

  As a result, in the tray 4, the paper discharge destination (front end side) is lifted, and the moment when the paper is discharged from the printer main body 2 onto the tray 4 is weakened. As a result, it is possible to prevent the paper from falling from the tray 4. Further, as described above, the inkjet printer device has a big problem that the color is shifted when the paper is misaligned. However, in the tray 4 of the above-described inkjet printer device, the paper is placed on the side where the paper is placed. There is no obstacle such as a stand to prevent paper discharge. For this reason, the paper does not shift in position as the paper is discharged, and therefore no color shift occurs.

  In addition, the tray 4 is a single unit, and the number of parts can be greatly reduced as compared with a tray that extends in stages, which is applied to a conventional inkjet printer apparatus. Further, such a tray 4 can be easily formed by resin molding, and the manufacturing cost can be greatly reduced.

  Further, in this ink jet printer apparatus, in the rail rib 6 and the guide rib 7 for lifting the front end portion of the tray 4, as shown in FIG. 11, the rail rib 6 is a portion of the guide rib 7 facing each other when the tray 4 is pulled out. 7a and 7b are sandwiched from below. Thereby, the movement in the direction substantially orthogonal to the pulling-out direction of the tray 4 can be restricted to prevent the tray 4 from rattling. This will be described.

  First, in a state where the tray 4 is stored in the tray storage unit 3, the movement in the direction substantially orthogonal to the pulling-out direction is restricted by the peripheral wall portion of the tray 4 being in contact with the side wall portion 3 a of the tray storage unit 3. Will be.

  However, as shown in FIG. 12, when the tray 4 is pulled out, the area where the peripheral wall portion of the tray 4 contacts the side wall portion 3a is reduced. Therefore, the tray 4 is easy to move in a direction substantially orthogonal to the pull-out direction as indicated by the arrow 33. At this time, the rail rib 6 provided on the tray 4 is sandwiched between the mutually facing portions 7a and 7b of the guide rib 7 provided on the tray storage portion 3. Thereby, the movement of the tray 4 in the direction indicated by the arrow 33 is restricted, and the tray 4 can be prevented from rattling.

  In the embodiment, the ink jet printer apparatus has been described as an example. However, the tray 4 and the tray storage unit 3 described above are not limited to the ink jet type, and other types of printers other than the ink jet, such as a laser type, for example. It can also be applied to a device.
