By the way, the paper feed roller 23 is a wheel 23.
a is a rubber roller 23b, and the feed roller 43 is a wheel 43a and a rubber roller 43b. Only the rubber rollers 23b and 43b can be replaced when worn.

Further, reference numeral 63 in the drawing denotes a sponge roller, and this sponge roller 63 contacts the paper feed roller 23 and the feed roller 43 and rotates, and at this time, both rubber rollers 23b and 43b are cleaned, The frictional force is always constant.

Next, FIG. 2 is a perspective view showing an essential part of the present invention, in which reference numerals 51, ...

As shown in the figure, the pin wheel 50 has a bearing portion 52 and a collar portion 53, and the protruding needles 51 are provided on the outer periphery of the collar portion 53 at equal intervals.

The projecting needle 51 is a needle made of a hard metal such as stainless steel, and is embedded in a small hole 54 formed in the outer peripheral surface 53a of the collar portion 53, and its tip is 1 to 2 m from the outer periphery of the collar portion 53.
It projects about m.

Further, in the figure, reference numeral 55 is the above-mentioned one-way clutch, 56 is a ring spring, and 57 is a steel ball.

The one-way clutch 55 is fitted in the bearing portion 52, so that the pin wheel 50 can idle in only one direction as described above.

Further, the steel ball 57 is disposed in a tapered hole 58 penetrating the bearing portion 52, and is supported by a ring spring 56 fitted in an annular groove portion 59 formed in the bearing portion 52.

On the other hand, reference numeral 70 in the figure is the above-mentioned rotary shaft,

When the pin wheel 50 is mounted on the rotary shaft 70, the notch groove 72 and the steel ball 57 are fitted to each other, so that the pin wheel 50 is fixed to the rotary shaft 70.

As the fixing means, a screw hole may be formed in the bearing portion 52, and the pin wheel 50 may be detachably fixed by a screw screwed into the bearing hole.

As a means for fixing the protruding needle 51, a radial groove may be formed on one surface of the collar portion 53 and extends to the outer peripheral surface 53a, and the base end of the protruding needle 51 may be fixed thereto. By the way, the pin wheel 50 can be attached and detached safely and easily by pinching the bearing portion 52 without touching the protruding needle 51.

Next, FIG. 3 is a plan view showing the sheet feeding device. In the figure, reference numeral 81 is a clutch and 82 is a pulley.

As is apparent from this figure, a pulley 82 is provided at the other end of the drive shaft 12 via a clutch 81, and the power of a motor (not shown) is provided on this pulley 82.
The power of the drive shaft 12 is transmitted intermittently via the clutch 81.

On the other hand, as is clear from this figure,
The rotary shaft 70 is penetrated into the pressure adjusting unit 30 as described above,
It is rotatably supported.

The pressure adjusting unit 30 includes a knob 32 for rotating the cam shaft 31, and an eccentric cam 3 fixed to the cam shaft 31.

The sliding contact force of the brake shoe 36 and the torque of the rotary shaft 70 can be increased or decreased according to the amount of operation of the knob 32.

The knob 32 is for timely operation in accordance with the quality and thickness of the fed paper. For example, if the knob 32 is operated to increase the sliding contact force of the brake shoe 36, the tension of the timing belt 61 is increased. The swing arm 13 swings downward against the tensile force of the wire 14a because it increases, and the tension of the timing belt 61 decreases when the sliding contact force is weakened, so the swing arm 13 moves toward the wire 14a. It is pulled by and swings upward.

Therefore, since the frictional force between the paper and the feed roller 43 can be adjusted by operating the knob 32, papers of different paper quality and paper thickness can be fed one by one, and when the pin wheel 50 is mounted. Since the biting force of the protruding needle 51 can be adjusted, a required biting force can be obtained according to the thickness of the bundle of sheets.

FIG. 4 shows this state. For example, when the feed roller 43 is at the position indicated by the solid line, the knob 32
When the torque of the rotary shaft 70 is increased by operating, the tension on the lower side of the timing belt 61 increases.
3 swings downward as shown by the imaginary line.
