The present invention relates to a manual feed mechanism capable of continuously copying a stack of sheets of paper, and more particularly, to a paper sorting apparatus of a manual feed mechanism for controlling the alignment of sheets of paper loaded on the manual feed tray and entering the feeder.

In general, the manual feed mechanism functions to feed paper of various sizes into the main body as needed, unlike a paper feeding cassette in which standard paper is normally loaded. However, the conventional manual feeding mechanism has been cumbersome to set the paper of various sizes one by one, and a paper sorting device capable of loading and continuously feeding a plurality of sheets of paper has been required. Therefore, in order to meet the above demand, the paper sorting device of the manual feed mechanism has been proposed in accordance with the patent application No. 91-19004 filed by the applicant of the present application, the configuration and operation state of the first and second If briefly described with reference to the drawings as follows.

FIG. 1 is a schematic view showing an embodiment configuration of a paper sorting device of a conventional manual feed mechanism, and FIG. 2 shows an operation state of a paper sorting device of a conventional manual feed mechanism. (A) shows that the leading edge of the paper is connected to the stopper. (B) shows the state in which the paper is fed.

In the drawing, 21 is the drive shaft, 22 is the circular gear, 23 is the feed roller, 24 is the idle gear, 25 is the longitudinal gear, 26 is the pickup roller, 27 is the moving shaft, 28 is the side plate bracket, 29 is the solenoid, 30 is the lever bracket, 31 is a spring, 32 is a stopper, 33 is a manual feeder, 34 is a stopper jammer, 35 is a sensor, 36 is a detection support, 37 is a paper detection piece.

As shown in the figure, a feeding roller 23 having a circular gear 22 on one side is inserted and driven at a predetermined position of the drive shaft 21 driven by power from the outside, and the circular shaft 22 ), The pick-up roller 26 having the longitudinal shaft 25 is fitted to the moving shaft 27 so as to be rotated by the power of the idle gear 24, and rotates in the same direction as the feed roller 23.

In addition, a solenoid 29 driven according to a copy start signal is mounted at an outer predetermined position of the side bracket 28 in which a predetermined long hole groove 28a is formed so that the moving shaft 27 is inserted and moved. A spring (31) connected to the lever bracket (30) and vertical movement according to its driving, one side is connected to the side plate bracket 28 and the other side is connected to the lever bracket (30) to provide its upward support force ), The moving shaft 27 moves up and down according to the ON-OFF of the solenoid 29.

The stopper 32 fitted at the predetermined position of the moving shaft 27 aligns the tip of the paper loaded in the manual feed tray 33 when the solenoid 29 stops driving and controls the inflow to the paper feed side. In addition, the stopper 32 is fixed to the body bracket to block the rotation thereof so that the stopper 32 can align the tip of the paper.

A detection letter 35 fixed to the body bracket to be located at one side of the stopper engaging piece 34, and a detection letter to enter and exit the light receiving area of the light emitting part and the light receiving part of the detection sensor 35 according to the presence or absence of the paper. It consists of a sheet detection piece 37 connected to the zone 36.

Referring to the working state of the conventional design configured as described above are as follows.

As shown in the drawing, when the multipurpose feeder 33 is opened and the paper is loaded, the paper is aligned on the lower side of the stopper 32, so that the stopper 32 cannot be rotated counterclockwise by the paper. The stopper jamming piece 34 is blocked, and the paper detection piece 37 is pushed by the paper to be separated from the light receiving area of the detection sensor 35 so as to turn on the detection sensor 35. Is detected. Here, the feed roller 23 and the pickup roller 26 are in a state where the driving is stopped, the moving shaft 27 is the lever bracket 30 is supported by the tension force of the spring (31).

When the copier copy signal is input, the paper feeder and the pickup unit rotate to pick up the paper. When the driving power is applied to the solenoid 29 and the lever bracket 30 is moved downward, the moving shaft spans the lever bracket 30. 27) is moved downward. Accordingly, the upper end of the stopper 32 is also separated from the stopper engaging piece 34 and rotated in the counterclockwise direction, thereby preventing the insertion of the paper into the main body and feeding the paper to the paper feed side.

When all the paper loaded on the multi-purpose tray 33 is fed, the paper detection piece 37 is inserted into the detection area of the detection sensor 35 to detect the absence of the paper, and the solenoid 29 by this signal. ) Returns the stopper 32 to its original position by one ON-OFF operation.

In the conventional paper sorting device configured and operated as described above, when the new paper is loaded into the manual feeder during copying, the stopper is separated from the stopper jam, so the paper is not aligned. It often occurs at the front or the back, and the paper jam is often caused by the starting point of paper feeding between papers, or the unfeeding and the double feeding. Therefore, when the new paper is to be loaded further, the previously loaded paper is removed, and the solenoid is turned on once and returned to the state as shown in FIG. 2 (a) by the stopper's own weight. The loaded paper and the new paper must be set together, and the configuration is complicated and requires a separate control means for operating the stopper.

Therefore, the present invention has been devised to solve the above problems, and as an attachment of the mechanism using the eccentric force characteristic of the mechanism, it needs to have a separate motion control means by moving the center of gravity of the stopper itself to have an eccentric force. An object of the present invention is to provide a paper sorting device of a manual feed mechanism that aligns the leading edge of a new paper that is further loaded on an existing paper loaded on the manual feed tray.

In order to achieve the above object, the present invention provides a drive shaft driven by receiving a driving force from the outside, a feed roller inserted and driven by the drive shaft, a moving shaft connected by the drive shaft and a power transmission means, and moving up and down; A paper sorting device of a manual feed mechanism provided with a pickup roller fitted to the moving shaft so as to be provided at the front end side of the paper feed roller, and a manual feed tray having a cut-out hole at a predetermined position, the predetermined distance between the drive shaft and the moving shaft. Located in the space, one side is connected to the main body, the stopper bracket having a hinge in the front predetermined position; Is inserted into the hinge so as to be eccentric so that the weight of one side is greater than the other side, one side is provided with a paper alignment piece for aligning the front end of the paper to be inserted into the incision hole, the other side is rotated across the lower end of the moving shaft It provides a stopper is provided with a restraint.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings of FIGS. 3 and 4.

In the drawing, 1 is a drive shaft, 2 is a feed roller, 3 is a pickup roller, 4 is a moving shaft, 5 is a stopper bracket, 6 is a hinge, 7 is a stopper, 8 is a stand, 9 is a protrusion, 10 is a multipurpose feeder, 10a Indicates the incision holes respectively.

As shown in the figure, the present invention is a modification of one embodiment of the paper alignment apparatus in the conventional configuration, and feeding at a predetermined position of the drive shaft 1 driven by receiving a driving force from the outside in response to a copy start signal. The roller 2 is fitted, and on the front side thereof, the pickup roller 4 is fitted to the moving shaft 4 which moves up and down. Here, the moving shaft 4 is moved up and down by driving the lever bracket connected thereto according to the on-off (OFF) of the solenoid (see FIG. 1). And, the lower side of the moving shaft 4 is located in the manual feed tray 10 is formed a cut hole 10a of a predetermined size.

Further, a stopper bracket 5 having a predetermined size connected to one side of the main body is provided at a predetermined position between the drive shaft 1 and the moving shaft 4, and a hinge 6 serving as a center of rotation at a predetermined position on the front surface thereof. Is provided to protrude.

On the other hand, the stopper (7) fitted to the stopper bracket (5) is configured to be rotated by being fixed to the hinge (6) so as to be eccentric so that the weight of one side is greater than the other side. And, on one side of the heavy weight of the stopper 7 is provided with a paper alignment piece for aligning the leading end of the paper is inserted into the cutting hole (10a), the other side of the light weight is the lower end of the movable shaft (4) By integrally forming the pedestal 8 of a predetermined size, the pedestal 8 is moved up and down as the movable shaft 4 moves up and down, so that the stopper 7 is hinged. It is rotated by eccentricity. At this time, the stopper bracket (5) on the rear side of one side is provided with a paper alignment piece in order to prevent the stopper 7 is rotated to a proper position or more by the inertia when the moving shaft (4) is moved downward momentarily When the stopper 7 is rotated clockwise by a predetermined interval in accordance with the downward movement of the moving shaft 4 by forming a protrusion piece 9 of a predetermined size so as to contact the protrusion piece 9 is the stopper bracket (5) One side of) will be restricted from being rotated any more.

Referring to the working state of the subject innovation constituted as described above are as follows.

As shown in FIG. 4 (b), when the paper is not fed, the paper feed roller 2 and the pickup roller 3 are in a stationary state, and the movable shaft 4 is provided with a side bracket (shown in the drawing). It is supported upward by the lever bracket provided on the outside.

Therefore, the force used to press the pedestal 8 spanning the lower end of the movable shaft 4 is released, so that the stopper 7 eccentrically fitted to the hinge 6 is rotated by the eccentric force to align the leading edge of the paper. Since the paper alignment piece is inserted into the cutout hole 10a of the multipurpose feeder 10, the paper alignment piece is aligned with the tip of the paper when the paper is loaded in the multipurpose feeder 10.

As shown in FIG. 4 (a), when paper is fed, when the drive shaft 1 is driven, the paper feed roller 2 and the pickup roller 3 rotate in the same direction by the power transmission means, At this time, when the solenoid is turned on and the lever bracket is pulled, the stopper 7 moves downward by pressing the pedestal 8 while the moving shaft 4 moves downward. By rotating, the sheet sorting piece located in the cutout hole 10a of the multipurpose feeder 10 is moved upward. Therefore, the paper is located away from the path entering the copier so that the paper on the multipurpose feeder 10 is fed by the number of sheets indicated on the operating panel of the copier.

Here, the projecting piece (9) is provided to restrict the excessive rotation of the stopper (7) due to the force in accordance with the downward movement by the drive shaft 4 is driven by the solenoid, the projecting piece (9) The stopper 7 rotates clockwise only by a predetermined interval when the moving shaft 4 is rotated downward to pick up the paper loaded in the same zone 10, and the protrusion piece (if it is rotated more than that) 9) and the stopper bracket 5 in contact with each other to prevent further rotation so that the excessive rotation of the stopper 7 is controlled.

In addition, when attempting to load new paper more during copying, if the copying number key is stopped, the solenoid is turned off as the moving shaft 4 rises, and the stopper 7 also rotates by an eccentric force. As a result, the other side of the stopper 7 is positioned in the cutout hole 10a in the first sheet alignment state.

If, at this time, the previously loaded paper is positioned forward in part, the stopper 7 is positioned on the uppermost paper, thereby aligning the leading edge of the additionally loaded paper.

The present invention, which is configured and works as described above, overcomes the inconvenience of having to remove previously loaded paper and stacking the new paper together when copying is required during copying. Since the operation does not require a separate drive control means has the effect of reducing the manufacturing time and cost.
