In general, the paper used for printing the facsimile machine is used in the high-grade facsimile, but the general printing paper is used, but most thermal recording paper is used. Since thermal recording paper is rolled, it must be cut at appropriate intervals, so most fax machines have a recording paper cutting device, and mainly a small cutting method is adopted.

In the small paper type recording paper cutting device, as shown in FIG. 1, a fixed blade 10 fixed at right angles to the discharge direction of the recording paper and an arm 13 bent at right angles on both sides are formed. 13 is engaged with the hinges 11 on both sides of the rear part of the fixed blade 10 to rotate up and down to engage the fixed blade 10 to cut the recording paper, and to operate the movable blade 12. It consists of a driving means. In addition, the driving means is connected to the motor 14, the worm 16 fixed to the end of the shaft 15 of the motor 14, the worm wheel 17 rotated in engagement with the worm 16, and the worm wheel 17. Eccentrically fixed cam pin (18), one end is fixed to the cam pin (18), the other end is connected to the rear end of the arm (13) of the movable blade (12) link (19) for converting rotational movement into reciprocating motion It is composed of

In addition, the recording paper guide 20 is spaced apart at intervals enough to pass the recording paper in front of the recording paper cutting device, the top and bottom is provided with a recording paper guide 20 through the recording paper guide 20, the fixed blade 10 of the recording paper cutting device ) And the movable blade 12 are guided.

In this configuration, when the recording paper is discharged between the movable blade 12 and the fixed blade 10 through the recording paper guide 20, and the cutting signal of the recording paper falls, the motor 14 operates to warm the worm 16. And rotate the worm wheel 17, the cam pin 18 is installed eccentrically to the worm wheel 17 is pulled and pushed one end of the link 19 while rotating in a constant track. By this operation, the link 19 rotates the rear side of the arm 13 of the movable blade 12 up and down, so that the movable blade 12 rotates up and down about the hinge 11 to the fixed blade 10. Meshes with.

At this time, when the movable blade 12 is formed to be inclined and engaged with the fixed blade 10, one side end is first crossed, such as small beans, and the other end is later crossed, so that the recording paper is cut.
