A spring 22 for pressing the second support member 4 inwardly (to the left in FIG. 1) using the plate 21 as a substrate, and a concave surface of the inwardly extruding portion 9 and the outwardly extruding portion 18 are placed in a normal state (in a non-operating state). A guide member 23 (FIG. 2 and Figure 3).

In the structure of the holder described above, the holders are combined as follows to hold a roll of copy paper.

That is, the locking mechanism 10 provided on the first support member 3
Push the protruding head of the stop plate 15 against the bullet 14, position the hole of the stop plate 15 and the central axis hole of the inward extrusion part 8 on the same line, and Insert the center rod 7 so as to pass through a certain hole, and when the stop plate 15 comes to a position corresponding to one ring groove 5 of the center rod 7, release the pressing force on the head of the stop plate 15. Then, the hole of the stopper plate 15 is removed from the position corresponding to the central axis hole of the inward extrusion part 8, and the ring groove 5 and the stopper plate 15 are engaged, so that the first support member 3 is aligned with the center axis. It is fixed and held at a predetermined position on the rod 7.

After that, the center rod 7 holding the first support member 3 is held so that one end edge of the cylindrical core 2 of the rolled copy paper 1 is fitted onto the outer periphery of the inwardly extruded portion 8 of the first support member 3. The second support member 4 is inserted into the center of the rolled copy paper 1 as shown in FIG. locking mechanism 16
The engagement position between the stop plate 21 provided in the second support member 4 and the ring groove 6 is determined in advance by the elasticity of the spring 22.
is configured so that the rolled copy paper 1 is pressed by the inner surface of the outer circumferential portion of the second support member 4. , the second support member 4 is held and engaged with the center rod 7 by further pushing inward.

Therefore, an important feature of the present invention is that the second support member 4
A protruding pipe 24 is provided on the outer surface of the protruding pipe 24 .
When the second support member 4 is fixed to the predetermined position of the central rod 7, the end 7a of the central rod 7 has a predetermined length 1.
The reason is that it is constructed with a protruding length.

That is, in this embodiment, as shown in FIG.
8 is provided with a protruding tube 24 having a hole having the same diameter as the bearing hole of the outwardly extruded portion 18 so as to protrude outward (rightward in FIG. 1).

The protruding length of the protruding tube 24 is the same as that of the rolled copy paper 1 in FIG.
The end portion 7a of the central shaft rod 7 is formed to have a length such that it protrudes by a predetermined length from the outer end of the protruding tube 24 in a state in which the central rod 7 is held.

The above-mentioned predetermined length is defined by the structure of the support section for the roll-shaped copy paper 1 provided in the paper feed section of an electrostatic copying machine.

For example, as shown in FIGS. 4 and 5, the shaft racks 32.
32' has a shape corresponding to both ends of the central rod 7, and the second support member 4 is securely engaged, that is, the stop plate 21 and the ring groove 6 of the central rod 7 are connected. The length of the protruding tube 24 is determined so that the inner surface of one frame 31' and the outer end of the protruding tube 24 substantially coincide with each other in the engaged state.

Therefore, as described above, the central axis rod 7 of the second support member 4
, the second locking mechanism 16 is moved inward to a position where the stop plate 21 provided on the locking mechanism 16 and the ring groove 6 of the central shaft rod 7 are securely engaged. If it is not pushed, the end of the central shaft rod 7 will not protrude by a predetermined length 1 from the outer end of the protruding tube 24 provided in the second locking mechanism 16, that is, the central shaft rod 7 will not be When the paper portion 30 is horizontally mounted on the shaft mounts 32, 32' of the frame 31° 31' on both sides, the outer end of the protruding tube 24 comes into contact with the shaft mounts 32', so that the central shaft 7 The rolled copy paper 1 cannot be loaded into the machine paper feed section 30 via the .

Therefore, the operator recognizes that the attachment of the second support disk 4 is incomplete due to the inability to attach the rolled copy paper 1, and re-attachs the second support member 4 securely. By correcting this, it is possible to know the uncertain state of loading of the roll copy paper before the copying operation.

In this embodiment, a locking mechanism is attached to each of the first and second support members, and a protrusion tube is provided to the second locking mechanism, but the protrusion tube may be attached directly to the support member. Furthermore, it would not depart from the technique of the present invention to provide both the first and second support members.

Therefore, according to the present invention, it is possible to prevent the rolled copy paper from being attached to the machine body while the attachment of the second support member is uncertain. It is possible to eliminate all the problems caused by the uncertain attachment of the conventional holder, such as falling off from the holder, not being able to smoothly feed the rolled copy paper, skew feeding, and paper jams.
