DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a paper discharge tray according to an embodiment of the present invention attached to a copying machine, FIG. 2 is a side view of the same, and FIG. 3 is a top view of the envelope paper in a spread state.
As shown in FIG. 1, the paper discharge tray 10 is attached to the paper discharge unit of the copying machine 11.
[0022]
The sheet discharge tray 10 has a bottom surface 12, standing parts 13 formed on both sides of the bottom surface 12 by bending upward from the attachment base (upstream end portion in the sheet discharge direction) to the copying machine 11, and the bottom surface. 12 and a stopper 14 formed by bending the center of the tip (downstream end in the paper discharge direction) upward. Note that the bottom surface 12 at the tip of the standing piece 13 is indicated by a broken line because the envelope paper 1 is placed thereon, but is in a tapered state.
[0023]
Further, since this portion is a portion that receives the ear portion 1a formed at the front end of the envelope paper 1 in the paper discharge direction, it is slightly longer than the length of the ear portion 1a. Even if this portion is not present, that is, even when the standing piece 13 is formed up to the tip of the bottom surface 12, the envelope paper 1 can be stacked on the bottom surface 12 although it bends slightly.
[0024]
The copying machine 11 includes a paper discharge roller 20 in a paper discharge unit, and the envelope paper 1 is discharged in the direction of arrow C.
The standing piece 13 of the paper discharge tray 10 is low on the upstream side in the paper discharge direction and is high on the downstream side, but the height X2 up to the upper edge 13a is also high in the downstream portion that is high. The height from the attachment position 10 to the attachment position (discharge position) of the discharge roller 20 is X1 or less.
[0025]
As shown in FIG. 3, the envelope paper 1 has a width (length in a direction perpendicular to the paper discharge direction) of Z1, and the edge portion 1a has a width of Z2 (Z2> Z1).
The width Z3 of the bottom surface 12 of the discharge tray 10 is between Z1 and Z2 (Z1 ≦ Z3 <Z2). Therefore, since the width between the pair of upright pieces 13 formed by bending both sides of the bottom surface 12 upward is shorter than the width Z2 of the ear 1a, the ear 1a formed on the front end side of the envelope paper 1 is discharged. At the time of paper discharge by the roller 20, the paper is placed on the upper edge 13 a of the upright piece 13 and is lifted from the bottom surface 12 as it is.
[0026]
The leading edge 13b of the standing piece 13 is vertical. That is, part A (the angle formed by the horizontal upper edge 13a and the standing edge 13b) is a right angle.
As a result, when the ear portion 1a is removed from the tip of the upper edge 13a, the envelope paper 1 is dropped substantially vertically in the D direction and stacked as shown in FIG. Therefore, the bottom surface 12 in front of the upright piece 13 only needs to be the length of the ear portion 1a. That is, the margin d can be small. The leading edge of the envelope paper 1 hits the stopper 14 and is prevented from popping out.
[0027]
The upper edges of the upright pieces 13 having different heights are connected by an inclined edge 13c, and the continuous portion (the part B) of the upper edge 13a and the inclined edge 13c on the downstream side ensures the ear 1a of the envelope paper 1. In order to follow, the arc portion has a large curvature.
The position Y1 of the leading edge 13b of the standing piece 13 is different from the attachment position Y2 of the tag 2. As a result, the envelope paper 1 can be dropped without affecting the sticky note 2.
[0028]
In the present invention, the ear 1a of the envelope paper 1 discharged by the paper discharge roller 20 is received by the upright piece 13 and is discharged from the bottom surface 12 so that the ear 1a is The envelope paper 1 drops to the bottom surface 12 when the leading edge is passed. Since the leading edge of the envelope paper 1 is ahead of the sticky note 2 at the time of dropping, the sticky note 2 is not pushed out or entered into the sticky note 2.
[0029]
