The first drive motor 41 transmits power to the feeding roller 30.

The encoder gear 42 is fixed to the shaft 44 to rotate by receiving the power of the first drive motor 41 to the shaft 44.

In addition, the encoder gear 42 has a plurality of slits 43 arranged on the outer circumference thereof, and among the slits 43, the slits 43 facing the friction part 31 have a narrow width and the remaining parts except the friction part ( 32 and corresponding slits 43 are preferably relatively wide in width.

As shown in FIG. 4, the encoder gear 42 has narrow widths of the slits 43 corresponding to a portion 'a' corresponding to the width A of the friction part 31 in the feeding roller 30. However, in the feeding roller 30, the slits 43 corresponding to the portion 'b' corresponding to the width B of the remaining portion 32, not the friction portion, are relatively wide in width. The function of this configuration will be described in detail in the slit sensor 72 section below.

The auxiliary roller 50 rotates in the opposite direction of the direction in which the object 10 is discharged at the time when the feeding roller 30 releases the object 10.

The interaction between the slit sensor 72 and the encoder gear 42 is as follows.

When the slit detecting sensor 72 detects the slits 43 corresponding to the portion 'a' of the encoder gear 42, the widths of the slits 43 are narrow, so that the interval of the electrical signal, that is, the on / off pulse signal is increased. It will be narrow.

However, when the slit detection sensor 72 detects the slits 43 corresponding to the 'b' part, the width is relatively wider than the slits 43 corresponding to the 'a' part. The interval of the off pulse signal will be wide.

Here, when the interval of the on / off pulse signal detected by the slit detection sensor 72 is narrow, the first driving motor 41 is accelerated, and when the interval of the on / off pulse signal is wide, the first driving is performed. The motor 41 is driven at constant speed.

On the other hand, the central processing unit 73 is the feeding roller 30 in the remaining portion 32, except for the friction portion, which is the point at which the discharge of the object 10 starts at the end of the discharge of the object 10, as shown in FIG. ) Controls the first drive unit 40 to rotate at a constant speed.

At the same time, the central processing unit 73 controls the second drive unit 60 so that the auxiliary roller 50 is stopped.

The present invention is the first processing unit so that the feeding roller 30 is accelerated in the friction portion 31 which is the point at which the discharge of the object 10 ends when the central processing unit 73 starts to discharge the object 10 as described above. Since the driving unit 40 is controlled, and at the same time, the auxiliary roller 50 controls the second driving unit 60 so as to rotate at a constant speed in the reverse direction of the direction in which the object 10 is discharged, the object (by the feeding roller 30) Since the secondary roller 50 blocks the subsequent object from being discharged while the sheet 10) is discharged one by one, there is an excellent effect of accurately matching the discharge demand number and the actual emission number.

In addition, in the present invention, the first drive unit may be configured to accelerate the feeding roller 30 in the friction part 31, which is the point at which the discharge of the object 10 ends when the central processing unit 73 starts to discharge the object 10. The second drive unit 60 may be controlled to control the 40 and at the same time to stop the auxiliary roller 50. At this time, the auxiliary roller 50 is preferably made of a material having a larger coefficient of friction than the object (10).

Even if the auxiliary roller 50 is operated as described above, since the auxiliary roller 50 can block the subsequent object following the auxiliary roller 50 from being discharged one by one by the feeding roller 30, the discharge demand It can have the effect of accurately matching the number of sheets and the number of actual emissions.
