Abstract

PURPOSE:To eliminate the need for using shaft for installing a roll of paper in a unit and reduce cost and make the operation smooth by rotatably fitting collars, which are fitted in a cylindrical core of said roll of paper, to flanges forsupporting said roll of paper in a spool. CONSTITUTION:A spool 1' consists of flanges 4', which support a roll of paper 2 for recording. Collars 8 are rotatably fitted over the supporting parts 6', which are projectingly provided at the central part of the flanges 4', while the outer surfaces 9 of the collars 8 are fitted in the core 5 of a roll of paper 2. The flange 4' is made of a flexible synthetic resin, and the collar 8 is made of a synthetic resin etc. having smaller friction coefficient, respectively. The roll of paper 2 is installed on the flanges 4', through the collars 8. Thereby, the conventional shaft for installing the roll of paper 2 in a unit can be eliminated, the cost of the unit can be reduced, and the roll of paper 2 can be smoothly delivered.

Description

Detailed Description of the Invention (al) Technical Field of the Invention The present invention relates to a spool used for mounting recording roll paper used in facsimile machines, copying machines, etc. about.

(bl) Prior Art and Problems An example of the conventional method will now be described with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view showing the spool attached to the device, and FIG. 2 is a sectional view showing the structure of the spool.

As shown in FIG. 1, the spool l is for loading the roll paper 2 into the device 3, and is used to hold the coal paper 2 in a proper position in the device 3 and to smoothly move the roll paper 2 against the device 3. It works to bring out

To explain the structure of the spool 1 with reference to FIG. 2, the flange 4 includes a support part 6 that fits inside the cylindrical core 5 of the roll paper 2 and supports the roll paper 2, and a support part 6 at both ends of the roll paper 2. The shaft 7 is inserted through the center of a flange 4 inserted into the shaft 7 to attach the roll paper 2 to the device 2.

In order to attach the roll paper 2 to the spool 1 having such a configuration, it is sufficient to simply insert the supporting portions 6 of the flanges 4 protruding from both sides into the core 5 of the roll paper 2.

Then, it will be attached to the device 3, but in this spool 1, the flange 4 is simply inserted into the core of 20 rolls of paper (8), so it is mechanically cantilevered.
Since the winding core has rough dimensions, it is unstable and lacks reliability, and since the metal shaft 7 is used, it is also expensive.

(C) Object of the Invention The object of the present invention is to solve the above-mentioned drawbacks, eliminate the expensive shaft, and provide a recording paper spool in which the flange and the roll paper fit together easily and the roll paper is smoothly fed out. It is in.

(d) Structure of the Invention In order to achieve the above object, the present invention provides a spool consisting of flanges that are inserted into both ends of a recording roll paper to hold the roll paper, the outer peripheral portion of which is attached to both ends of the roll paper. The flange is provided with a collar which is fitted inside the cylindrical winding core and rotatably fitted to a support portion whose center portion protrudes from the flange.

tel Embodiment of the Invention An embodiment of the invention will be described below with reference to FIGS. 3 and 4.

FIG. 3a is a side sectional view of a recording paper spool according to the present invention, and FIG. 4 is a view taken along the arrow A-A' in FIG. FIG.

In the drawings, 1'' is a spool, 4'' is a flange, 6'' is a support portion, and 8 is a collar.Those with the same reference numerals are the same throughout the plan.

As shown in FIGS. 3a and 3b, the spool 1' according to the present invention has a collar 8 rotatably fitted onto a support portion 6'' protruding from the center of a flange 4''.

The collar 8 is configured so that the outer peripheral portion 9 is inserted into the core 5 of the roll paper 2.

The flange 4' is made of flexible synthetic resin, and the collar 8 is made of synthetic resin with a low coefficient of friction.

Therefore, when the spool 1' having such a configuration is inserted into the roll paper 2, the roll paper 2 will be slightly rotated with respect to the flange 4' via the collar 8.

FIG. 4 shows the state in which the roll paper 2 is mounted on the device 3' using the spool 1' of the present invention. The device 3' has a tray structure with a triangular cross section, and the roll paper 2 with spools 1'' inserted on both sides is simply placed on the tray.Then, the recording paper is moved in the direction of arrow B. The roll paper 2 is pulled out and rotates in the direction of arrow C. At this time, as described above, the roll paper 2 rotates lightly with the collar 8 interposed between it and the flange 4'', so that the recording paper The drawer is drawn out smoothly, skewing and jamming can be prevented, and the motor torque required for drawing out is small, so a small and inexpensive motor can be used.

(f) As described in detail of the invention, by applying the recording paper spool of the present invention, it is possible to stably load the roll paper into the device, and it is also possible to pull out the recording paper accurately with less force. Ta.
