Abstract

PURPOSE:To eliminate necessity for replacement of sheet feed cassette when a copying machine for the purpose of enlarging and/or shrinking, by providing possibility of changing the orientation of transcript sheets for an angle of 90 deg. by means of an operation, for ex. switching. CONSTITUTION:When a sheet receptacle plate 2 is revolved 90 deg., a separation nail base-plate 22 is turned in the S-direction to cause disengagement of a sheet 1 from sheet separation nails 9, 9', and then a motor 27 is operated to allow one of the nails 9' to move along guide grooves 32, 33 in the direction as parting from the other nail 9. If then the motor 3 is rotated counterclockwise, a cam plate 17 rotates also, and the above-mentioned sheet receptacle plate 2 is also rotated through the action of pins 10, 11, which are guided along guide groove formed in the cam plate 17. During this rotation, the sheet receptacle plate 2 makes an eccentric rotation, so that a corner B of the receptacle plate 2 does not contact the separation nail shaft 13, to provide possibility of the receptacle plate 2 turning 90 deg.. Thus operation of replacing the cassette can be omitted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper feeding device p;l in a copying machine, and particularly to a paper feeding device in which the direction of the paper surface can be changed when the copying machine is used for variable magnification.

Recently, there has been an increasing demand for the ability to reduce or enlarge manuscripts when photographing them. Furthermore, current copying devices can easily convert between normal copying and reduced or enlarged copies.

However, if you consider general copying equipment, you will notice that in the case of normal copying, A4 size copy paper is sent as 4 sheets, and A4 size copy paper is transferred from A3 size original to A4 size document. When reducing and copying on floor copy paper, A4 size copy paper is often fed vertically, so when using a copying machine for such enlargement or reduction, it is necessary to Since the paper feed cassette and the paper feed cassette for navy blue feeding must be selectively replaced and set when copying JQ manuscripts for reduction or enlargement, it is inconvenient to replace the 1-inch paper cassette. It is something that is happening.

The present invention was developed in order to eliminate the drawbacks of the above PLi, and its purpose is to provide a sheet cassette printing system that allows the direction of copy sorting to be changed by 90 degrees by, for example, switching operations. It is something to do.

The present invention will be described below based on the embodiments shown in the drawings.
I will clarify.

Reference numeral 1 indicates a stack of sheets, and the sheet holder of this sheet 1 is placed on a plate 2. This 7-toe support has a motor 3 located at the bottom of the plate 2, and this motor 3
is supported by the motor number plate 4. The motor mounting plate 4 is rotatably attached to the cassette body 5 by a hinge plate 6 and a pin 7 fixed to the cassette body 5. The other end of the motor board 4 is supported elastically by a spring 8.

This is similar to Sheet 1, Sheet 1
This is to ensure that the sheet separation claw 9 can always come into contact with the sheet separation claw 9 under the same pressure condition. In other words, the fact that the sheet 1 is in contact with the sheet separating claw 9 with a constant pressure regardless of the loaded amount means that when the sheets 1 are fed one by one by a pick-up roller (not shown), 7-t1
will be reliably sent. Further, the seat support has pins 10, 11, and 12 protruding from the back surface of the plate 2,
As described later, the sheet 1 is rotated by the rotation of the rotary motor 3.
It has an important role in rotating.

A separation claw shaft 13 to which the sheet separation claw 9 is fixed is rotatably mounted by a separation claw bearing 14 fixed to the cassette body 5.

Further, a plunger 16 is connected to the tip of the lever 15 fixed to the separation claw shaft 13.
By the operation of step 6, the number of sheets N on the stacked sheet 1 is
1tj claw 9 can be detached from the sheet 1. This is activated when changing the orientation of sheet 1 -
It is something. 17 is a cam plate fixed to the drive shaft 3 of the motor 3, and this cam plate 17 is provided with cam grooves 18 and 19, which are clearly shown in FIG. In the seat receiver, the bins 10 and 11 protruding from the plate 2 are loosely fitted. Further, a cam plate 20 is fixed to the motor mounting plate 4, and the cam plate 20 is provided with an arc-shaped guide 21, and the front seat holder is connected to the plate 2 in the guide groove 21. bottle 1 protruding from
2 is loosely fitted.

Reference numeral 22 denotes a separation claw substrate to which one of the sheet separation claws 9 is attached, and the other sheet separation claw 9' is movably held. That is, when the plunger 16 does not operate, the separation claw substrate 22 is
is not working! μ (is pulled by springs 23 and 24 installed between the separating claw board 22 and the cassette body 5, and is stopped at the stopper 25, 26 position, so that the note separating claw 9°9 is pulled from the edge of the sheet 1. 27 is a motor fixed to the separating claw board 22, and the motor 27 is a reversible motor that can rotate in forward and reverse directions. Wires 30 and 31 are wound around wire pulleys 28 and 29 fixed to both ends of the drive shaft, and the ends of these wires 30 and 31 are connected to the sheet separating claw 9'. , is a guide groove provided in the sorting claw substrate 22, and the sheet separating claw 9' can be slid along this guide m32.33.34 indicates the sorting and separating claw 9' as shown in FIG. It is a tension spring that is always pulled to the position shown in .

The above is the structure of this embodiment.Next, its operation will be described.As shown by the solid line in FIG. Corner A
By positioning the corner B at the position, the 7-toe 1 can be moved laterally. In other words, the position of the sheet (from 6, since the sheet can be fed laterally by turning 90 degrees, the motor 3 is moved to the position C where AB=MB=MC=t/2 on the perpendicular line from the midpoint M of AB.
A drive shaft 3 is arranged. Therefore, Figures 1, 2, and 4
When changing from the vertical sorting state shown in the figure to the horizontal feeding state, that is, when rotating the sheet tray plate 2 by 90 degrees, first operate the plunger 16 to move the dividing claw base 22 to the horizontal state. In FIG. 4, the sheet 1 is rotated in the S direction to disengage the sheet separation claws 9, 9', and the motor 27 is further driven to remove the wire 30.

The notebook tray 2 is also rotated via the bin 10.11, which is guided by the notebook holder. When the plate 2 is rotated, the note holder is attached to the bottle 12 which is fixed on the plate 2.
is guided by the guide front 21 provided on the cam plate 2o, and the seat+&j plate 2 is rotated (li1i), so the seat receiver rotates without the plate 20 corner 11 coming into contact with the separation claw shaft 13. As for the sheet receiver, the plate 2 can change its direction.Thus, after changing the direction of the sheet 2, the sheet mite restores the 1 runger 16 and uses the elastic force of the spring 23 to raise the claw board 22 and move it to one of the sheets. By positioning the separating claw 9 at the corner of the sort, and further driving the motor 27 to position the other sheet separating claw 9' at the corner of the sheet, /
- Preparations are made to feed the sheets in a transversal state.

Converting the sheet 1 from the horizontal feeding state to the vertical feeding state is performed in the same manner. That is, while the 7-toe separating claws 9, 9' are feeding the cotton, the movable sheet separating claw 9' moves, and then the sheet 1 is rotated by the clockwise operation of the motor 3. In addition, the movable sheet separation claw 9 rotates the motor 127 and the wire boom! 728, 29 to wire 30.31

The note separating claw 9' is moved along the grooves 32 and 33 while being pulled by a spring 34 whose both ends are fixed to the separating claw base plate 22, and is fixed at the position in which the sheet 1 is vertically fed.
Furthermore, the plunger 16 is released and the position trapping sheet separating claw at the corner of the tray 1 is placed in place, completing preparations for feeding the sheet in the vertical position.

As described above, the present invention is a 7-sheet cassette device in which sheets are fed out one by one, in which a sorting cassette is provided with a displacement mechanism for displacing sheets loaded in the cassette by 90 degrees. Therefore, with this sheet cassette device, it is possible to very easily and reliably change the orientation of the sheets in the cassette, which is necessary when enlarging or reducing a copy of a document, using, for example, an electrical signal. It is possible to eliminate the work of replacing cassettes, and also to prevent copy errors.
