Abstract

PURPOSE:To facilitate taking out sheets from a bin tray by disposing a push member opposite to each bin tray, and moving an operating member with a sheet storing member to operate the push member, thereby sequentially moving only an arbitrary bin tray. CONSTITUTION:A sheet storing appartus B disposed adjacent to a copying machine A comprises a sheet sorting portion 8' having a plurality of bin trays 8 and a sheet sorting portion 9 which are disposed in a main body 7 thereof, wherein a sheet take-out opening 10 is formed on the rear wall 6. In this case, longitudinal feed screw rods 17 engaged with longitudinal tapped holes 16 formed on both ends of a lateral member 15 are rotated to move a sorting member 14 to a position opposite to a designated bin tray 8, so that a sheet transported by a transport member 13 is fed into the bin tray 8. After that, the storing member 14 is further moved to bring the high part 20a of a cam 20 into contact with the other end portion 18b of an arm 18 disposed opposite to the bin tray 8, and the arm 18 is turned to move the bin tray 8 to the sheet take-out side.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to paper storage devices such as sorters and collectors used in copying machines and the like.

Conventional paper storage devices such as sorters and collators have a paper storage section in which a plurality of pin trays are arranged at predetermined intervals, and a paper sorting section that is movable across each pin tray and feeds paper to a predetermined pin tray. The paper is sorted by storing the paper in the pin tray and taking out the paper from one edge of the pin tray perpendicular to the paper feeding direction.

All the pin trays are arranged so that one end edge of each pin tray is in the same position, and the sheets stored in each pin tray are arranged equally, so when taking out the paper from one end edge of the pin tray, However, there is a problem in that it is difficult to take out the paper because other adjacent pin trays or other papers get in the way.

This is particularly noticeable when the distance between the pin trays is narrowed in order to make the paper storage device small and compact.

Purpose of the Invention It is an object of the present invention to move only the bin tray to the paper take-out side when taking out stored paper, so that the paper can be taken out easily and reliably, and to simplify the structure for moving the bin tray. .

Structure of the Invention A push-out member is provided on the side opposite to the paper take-out side of the bin tray, facing each bin tray, and for sheet sorting, a moving member is provided on the member for sorting sheets, and for sorting, the moving member is moved together with the member. A push-out member is activated to move the bin tray sequentially toward the paper take-out side.

Example The present invention will be described in detail below with reference to the drawings.

FIG. 1 is an overall front view showing the copying machine A and the paper storage device B installed therein.

The paper storage device B includes an upper wall 1, a lower wall 2, left and right walls 3, 4,
A paper storage section 81 with a plurality of bin trays g and a paper sorting section 9 are provided in the main body 7, which is formed into a cylindrical shape by the front and rear walls 5 and 6. An opening 10 is formed. Note that the opening 10 may be opened and closed by a door.

The bin tray 8 is a plate-shaped body as shown in FIG. , and is movably supported along the guide 12 in a direction orthogonal to the paper feeding direction.

The paper sorting section 9 includes a conveying member 13 that conveys the sheets across each bin tray ε, and a sorting member 14 that is movable along the conveying member 13. It is configured to be fed and stored in the bin tray 8.
, 1 The sorting member I4 is provided in plural numbers on the horizontal member 15, and has vertical screw holes 16°1 formed at both ends of the horizontal member 15.
Vertical feed screw rods 17 and 17 are respectively screwed to the vertical feed screw rods 17 and 17, and by rotating the vertical feed screw rods 17 forward and backward, the sorting member 14 along with the horizontal material 15 moves up and down along the conveying member 13. It is.

On the side opposite to the paper take-out side of each bin tray 8, an arm I8 serving as a pushing member is swingably supported on a vertical shaft 19, and one end lgα of the arm 18(1) is the other end edge of each bin tray 8. 8b, the other end 18A faces the operating member cam 20 provided on the cross member 15, and each arm I8 has one end 18α spaced apart from the other end edge 8h of the bin tray 8. When the high part 20α of the cam 20 rides on the other end 18A, it swings clockwise so that the one end 18α comes into contact with the other end 8h, and the bin tray 8 is moved to the paper takeout side. In addition to drawing, sorting is performed by positioning so that when the member 14 passes through a predetermined bin tray 8 and paper feeding is completed, the high portion 20α of the cam 20 rides on the other end portion 18h of the arm 18.

In FIG. 3, 21 is a spring, 22 is a stopper,
The bin tray 8 is held in its original position in contact with the stopper (22).

Therefore, by rotating the vertical feed screw rod 17, the members 14 are sorted.
is moved to a position facing a predetermined bin tray 8, and after the paper conveyed by the conveyance member 13 is fed into that bin tray 8 and stored therein, the sorting member 14 is further moved, and the cam 20) high part 20α The arm IB contacts the other end 18h of the arm IB provided opposite the bin tray 8, swings the arm 18 clockwise, and moves the bin tray 8 against the spring 21 to one side for taking out the paper.

Then, the high portion 20α of the cam 20 is connected to the other end of the arm 18 +
8b, the bin tray 8 is moved by the spring 21 to the stopper 2.
It returns to its original position in contact with 2.

Because of this, by swinging the arm 1g facing the bin tray 8 from which paper is taken out using the cam 20,
Only that bin tray 8 can be moved to the paper take-out side and protrudes from the other bin trays 8, so that bin tray 8
When taking out the paper, the paper can be easily and reliably taken out without other bin trays 8 getting in the way or other papers getting in the way.

In addition, since the cam 20 moves together with the member 14 during sorting,
Move cam 20 Tj! There is no need to provide a special mechanism for moving the bin tray 8, and the structure for moving the bin tray 8 becomes simple.

Effects of the Invention Since any one bin tray 8 can be moved to the paper take-out side by moving the push-out member 18 using the operation member 20, when taking out the stored paper, only that bin tray 8 is moved to the paper take-out side. The paper can be easily and reliably taken out.

Further, the operation member 20 is used for sorting the sheets in the section 9 and the member 14 is used for sorting the sheets.
Since a mechanism for moving the operating member 20 is not required, the structure for moving the bin tray 8 can be simplified.
