[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a delivery mechanism for facilitating the delivery of paper from the storage unit in a paper feeding device for sequentially feeding the papers stacked and stored in the storage unit from the bottom end.

[0002]

[Prior art]

 Generally, it is often the case that the address, name, etc. are written by hand on paper such as a funeral guide postcard or a banquet card. However, since handwriting work is often covered by elderly people, it is desirable to automate this work. In this case, there has been considered a paper feeding device in which an outlet is provided at a lower end of a side of a storage unit that stores a large number of sheets stacked vertically and the sheets at the bottom of the stacked sheets are sequentially drawn out through the outlet. In this case, if the clearance at the outlet is fixed, only paper of the same thickness can be sent out. Therefore, there is a problem that a clearance adjusting mechanism is required so that different clearances can be obtained depending on the thickness of the paper to be drawn out, the structure becomes complicated and the cost becomes high.

[0003]

[The purpose of the device]

 SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide a paper feeding mechanism in a paper feeding device that can feed paper of different thickness without providing a special adjusting mechanism.

[0004]

[Means for achieving the purpose]

 In order to achieve the above-mentioned object, the printing apparatus according to the present invention forms a paper outlet at the lower end of the front side wall of an accommodating unit for accommodating a large number of thick papers in multiple stages, and has an elastic member near the front side of the outlet. The stopper which it has drooped down, the lower end part was made to incline forward.

[0005]

According to the above configuration, when the lowermost paper in the accommodation portion of the paper feeding device is fed toward the outlet, the paper comes into contact with the stopper that closes the front side of the outlet.

By the way, since the lower end of the stopper is formed so as to incline toward the front side, the paper bends the stopper when a sufficient feeding force is applied to the paper, so that the lower end of the stopper and the outlet port. A clearance is formed between and so that the lowermost paper can be drawn out. Since the feeding force for paper is applied only to the lowermost paper, only the lowermost paper is delivered.

As described above, as long as a sufficient feeding force is applied and the paper has a certain rigidity, the paper bends the stopper by the feeding force of the paper regardless of its thickness, and the paper at the lowermost stage of the outlet port is Open to the extent that it can be introduced. Therefore, only the lowermost paper is drawn out from the storage section. The second sheet from the bottom is returned to its original position by the elastic restoring force of the bent stopper.

【Example】

 FIG. 1 shows a paper feeding mechanism in the paper feeding device. The paper feeding device is provided with a lead-out port 3 at a lower end of a front side wall 2a of a storage part 2 for accommodating a large number of papers 1 stacked vertically. The feed roller 5 is arranged in the opening 4 formed at the bottom, and the feed roller 5 is driven to rotate so that the paper 1a at the lowermost stage is sequentially drawn out from the above-mentioned outlet 3, and in the vicinity of the front side of the outlet 3. Is formed with a stopper 4.

The clearance of the outlet port 3 is set to be large enough to lead out at least two sheets of expected maximum thickness.

The stopper 4 is formed by connecting a plate-shaped piece 4b made of synthetic resin or the like below the plate spring 4a. The upper end of the plate spring 4a is fixed to the side wall 2a, and the plate-shaped piece 4b is one of the outlets 3. It is installed so as to block the part. The lower end of the plate-shaped piece 4b is bent and formed so as to be inclined forward.

In the above configuration, when the feeding roller 5 of the paper feeding device is rotated, the contacting frictional force between the lower surface of the lowermost paper 1a in the accommodating portion 2 and the feeding roller 5 causes the paper 1a to be ejected. 3, the paper 1a comes into contact with the stopper 4 that closes the outlet 3.

By the way, since the lower end portion 6 of the stopper 4 is formed so as to incline toward the front side, when the paper 1a is given a sufficient feeding force by the feed roller 5, the paper 1a is fed as shown in FIG. Since the stopper 4 is bent as described above, a clearance is formed between the lower end portion 6 of the stopper 4 and the outlet 3 to the extent that the lowermost paper 1a can be led out. Since the feeding force for the paper 1a is applied only to the lowermost paper 1a, only the paper 1a is derived.

Next, when feeding a thick paper, the paper is fed in the same manner. In this case, the degree of bending of the stopper 4 becomes larger, but the feeding mode is the same as that in the case of thin paper thickness.

As described above, as long as a sufficient feeding force is applied to the paper 1a and the paper 1a has a certain rigidity, the paper 1a pushes out the stopper 4 and bends by the paper feeding force regardless of its thickness. The outlet port 3 is opened to the extent that the lowermost paper 1a is led out. Therefore, only the lowermost paper 1a is pulled out from the storage section 2. The second sheet of paper 1b from the bottom is lowered to the lowermost stage as shown in FIG.
