Generally, in a transfer type electrophotographic copying machine, a toner image is formed on a photoreceptor through charging, exposure, and development steps, and this toner image is transferred onto a transfer paper by a corona discharge means or the like. Thereafter, the toner image is semi-permanently fixed onto the transfer paper by a fixing device. Normally, paper having a weight of about 50 to 250 (g/m 2 ) is practically used as the transfer paper. Of these, approximately 60 to 90 (g/m 2 ) paper is used because of its high frequency of use and ease of automatic paper feeding.
The paper is stored in a paper feeding cassette or the like, and is reliably fed by an automatic paper feeding mechanism. However, for thick letters of 100 g/m 2 or more, a general automatic paper feeding mechanism cannot be used. Therefore, the current situation is that most of the paper is fed manually.

The pedestal 23 is used to control the rear end of the thick letter.
Both side edges are bent approximately 90 degrees to form a regulating piece 23 - 1 , and one end of a spring 26 that is pushed upward is fixed to an extension 23 - 2 at the center of the regulating piece 23 - 1 . Further, the pedestal 23 has a rotating shaft 29 attached to the regulating piece 23 -1 , and this rotating shaft 29 is pivotally supported in the elongated hole 22 -1 bored in the paper guide 22. It is rotated around this rotating shaft 29. The other end of the spring 26 is fixed to a spring holding member 27 fixed to the bottom of the cassette, and pushing down the extension 23-2 pushes the pedestal 23 upward. The paper position regulating member 25 has claw portions 25 -1 provided opposite the corner portions of both ends of the thick letter to regulate the position of the paper.
It is rotatably supported by the paper guide 22, and is provided with a hole 25-2 for regulating the rotation range. The hole 25-2 is connected to the paper guide 22.
A stopper 28, which is formed by appropriately cutting out and bending, is inserted through the stopper 28. In other words, the edge of the hole 25-2 is engaged with the stopper 28, so that the rotation range of the paper position regulating member 25 is regulated. A regulating claw 24 is fixed to the frontmost bent portion 25 -3 of this paper position regulating member 25 .
Between the claw portion 25 -1 and the tip of the regulating claw 24, there is a gap d as shown in FIG. 2 that allows a sheet of thick paper to pass through.

When the paper feeding roller 31 rotates, the uppermost thick letter 30 -1 is fed through the distance d between the claw portion 25 -1 of the paper position regulating member 25 and the tip of the regulating claw 24. At this time, the next thick letter 30 -2 is the regulation claw 2.
4, the paper feed is regulated, and only the uppermost thick letter 30-1 is fed as shown in FIG. The above claw part 25 -1
The distance d between the tip of the regulating claw 24 and the tip of the regulating claw 24 is equal to
The gap is such that two or more sheets cannot pass through.

The present invention further solves the above-mentioned problems, and a specific example thereof is shown in FIG. 6th
The figure is a perspective view showing the main parts of the paper position regulating member.
In other words, the present invention has a major feature in the paper feed port for feeding paper. In the figure, the paper position regulating member 250 is rotatably supported by the paper guide 22, and faces the corners of both ends of the thick letter.
A claw portion 25 provided to regulate the position of the paper
A hole 25 having a diameter of 0 -1 and having a restricted rotation range.
0 -2 is formed. A stopper 28 formed by appropriately cutting and bending the paper guide 22 is inserted into the hole 250 -2 , and the rotation range of the paper position regulating member 250 is restricted as explained in FIG. . The paper position regulating material 250 is
A regulating claw 250-3 for regulating the tip of the thick paper is integrally formed. Between the claw portion 250 -1 and the tip of the regulating claw portion 250 -3 , a distance d is formed through which a sheet of thick paper can pass. Further, an opening 250-4 is formed with a vertically increased interval regardless of the interval d between the claw part 250-1 and the regulating claw part 250-3 which face each other at both ends of the thick letter.
