Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a view schematically showing, for example, an optical character reading apparatus as a sheet processing apparatus according to a first embodiment of the present invention.

As shown in FIG. 1, the optical character reading apparatus 1 has a hopper table 2 on which a plurality of forms carried in the apparatus are loaded, and a slide on the upper surface of the forms loaded on the hopper table 2. The pick roller 3 and the feed roller 4 which come into contact with and take in the form inside the apparatus, and contact the lower surface of the form taken into the apparatus by the feed roller 4 and cooperate with the feed roller 4 to separate the form one by one. A plurality of upper transport rollers 7 and a lower transport roller 8 which are arranged opposite to the separation roller 6 and above and below the transport path 5 and transport the form to the downstream side while sandwiching the form from both sides; and a surface of the transported form. Light source 14 for irradiating light to the mirrors 10, 11 and lens 12 for guiding reflected light from the surface of the form to the CCD 13.
On the other hand, a back contact sensor 15 for reading an image of the back of the conveyed form, a print head 17 provided opposite to the platen roller 16 and for printing a serial number or the like on the processed form, The printing apparatus mainly includes stackers 19 and 20 that store a form that has been subjected to a predetermined printing process by the head 17 and carried out of the apparatus while being sorted by the flapper 18.

In the optical character reading apparatus 1 of the present embodiment, the stacked forms are separated and fetched one by one into a device in which the CCD 13 and the back surface contact sensor 15 are disposed. To do so, a form capturing mechanism 21 is provided.

As shown in FIG. 2 as a front view or FIG. 3 as a side view, this form taking-in mechanism 21 is used to separate a plurality of forms 22 one by one and take them into the apparatus. And rotate synchronously through
As described above, the pick roller 3 and the feed roller 4, which are in sliding contact with the upper surface of the uppermost form 22 loaded on the hopper table 2, and the one-way clutch (one way clutch) 6a, which is in contact with the lower surface of the form 22, are provided. This is realized by cooperating with the separation roller 6 configured so as not to rotate in the direction in which the form 22 is taken in (the direction opposite to the rotation direction C).

Further, such a form taking-in mechanism 21 includes:
The separation roller driving mechanism 2 for always extracting the best form separation ability from the separation roller 6 by making the wear of the surface of the separation roller 6 caused by sliding with the form 22 or the like uniform.

For example, a plate that contacts the peripheral surface of the separation roller 6 while pressing it in the direction of arrow F so that the separation roller 6 rotates in the same rotation direction as the feed roller 4 and the pick roller 3, that is, in the direction of arrow C due to the frictional force of each other. And a contact member 31 formed by a spring or the like.

Next, the operation of the separation roller 6 by the separation roller driving mechanism 24 configured as described above will be described. In the optical character reading device 1 according to the present embodiment, for example, the power of the device 1 is turned on, and the separation roller 6 is driven each time the operation of the device is started.

When the form 22 is not taken into the apparatus (when paper is not fed), the solenoid 29 is energized, and the iron core 27 is moved to the arrow X1.
In this case, the link lever 30 rotates (counterclockwise in FIG. 3). Thereby, as shown in FIG. 4 or FIG. 5, the movable plate 25 is separated from the separation roller 6 held by the movable plate 25 while resisting the urging force of the spring 27.
Together with the separation roller 6 and the separation roller 6 is released from the feed roller 4. At this time, since the peripheral surface of the separation roller 6 is pressed by the contact member 31, the separation roller 6 rotates in the direction of arrow C due to the frictional force generated as the separation roller 6 descends. In the optical character reading device 1 of the present embodiment, such operation control suppresses local wear of the separation roller 6 and extends the life of the separation roller 6.

On the other hand, when the energization of the solenoid 29 is stopped when the form 22 is taken into the apparatus (at the time of paper feeding), the urging force of the spring 27 causes the iron core 27 to move in the direction of arrow X1, and the link lever is moved. 30 rotates (clockwise in FIG. 3). Further, as shown in FIG. 2 or FIG. 3, the movable plate 25 moves up in the arrow Y1 direction together with the separation roller 6 held by the movable plate 25 by the urging force of the spring 27, and the separation roller 6 comes into contact with the feed roller 4. Is ready to be fed. At this time, although the separation roller 6 is in contact with the contact member 31, the separation roller 6 does not rotate in the direction opposite to the arrow C direction but simply slides on the surface of the contact member 31 and rises by the action of the one-way clutch 6 a. Will be. The separation roller 6 that has risen in this way presses the feed roller 4 by the urging force of the spring 27, and the feed roller 4 and the separation roller 6 cooperate with each other.
It is possible to separate a plurality of forms 22 one by one and take them into the apparatus.

As described above, the optical character reading apparatus 1 according to the present embodiment has the contact surface which comes into contact with the peripheral surface of the separation roller 6 for separating the forms 22 taken in by the pick roller 3 and the feed roller 4 one by one. The member 31 rotates the separation roller 6 in one direction with the movement of the separation roller 6 by the solenoid 29 that is a driving source. Therefore, in the optical character reading device 1 of the present embodiment, the separation roller driving mechanism 24 for suppressing local wear on the roller surface and extending the life of the separation roller 6 is a simple and simple driving source. Since the mechanism is simple, it can be realized as a small-sized and inexpensive device with a reduced number of components.

The optical character reading device 1 of the present embodiment
Then, the dirt on the surface of the separation roller 6 is removed and the separation roller 6 is removed.
Although no consideration was given to maintaining a constant separation ability, a cloth for cleaning the peripheral surface of the separation roller 6 was provided between the contact member 31 and the separation roller 6 as shown in FIG. The fiber member 32 may be interposed. As a result, for example, stains of the form 22 attached to the surface of the separation roller 6 due to fibers or the like can be removed, so that the separation roller 6 can maintain a constant separation ability, and the life of the separation roller 6 can be extended. Can be planned.

As shown in FIG. 7, two sets of pick roller 3, feed roller 4, and separation roller drive mechanism 24 are arranged in parallel so that forms 22 of various sizes can be stably taken in the apparatus. You may. Thus, for example, when feeding a small-sized form 22 that does not reach one separation roller 6, the other separation roller 6 is moved from the feed roller 4 while the other separation roller 6 and the feed roller 4 feed paper. The rotation operation of the separation roller 6 for separating and extending the life can be performed, and the sheet 22 can be fed quickly.

Next, a second embodiment of the present invention will be described. The optical character reading device of this embodiment is provided with a form taking mechanism 41 instead of the form taking mechanism 21 provided in the optical character reading device 1 of the first embodiment.

That is, as shown in FIG. 8, instead of providing the contact member 31, the separation roller driving mechanism 42 provided to the form taking-in mechanism 41 has the form 22 taken in by the feed roller 4 one by one. The separation roller 6 for separation is shifted downstream of the feed roller 4 in the transport direction H1 of the form 22 (the direction in which the form 22 is taken in). Thereby, as shown in FIG. 9, when the separation roller 6 rises in the direction of arrow Y1 and comes into contact with the feed roller 4, a moment acts to rotate the separation roller 6 in the direction of arrow C.

Therefore, in the optical character reading apparatus of the present embodiment, the separation roller driving mechanism 42 for suppressing local wear on the roller surface and extending the life of the separation roller 6 is provided.
Since it is a simpler mechanism than the separation roller drive mechanism 24 of the first embodiment, it can be realized as a low-cost device that can be reduced in size and has a reduced number of components.

Next, a third embodiment of the present invention will be described. The optical character reading device of this embodiment is provided with a form taking mechanism 51 instead of the form taking mechanism 21 provided in the optical character reading device 1 of the first embodiment.

The eccentric amount of the second support roller 54 is
As shown in FIG. 10, the first and second support rollers 53,
When the separation distance between the belts 54 is substantially minimized, the tension T1 of the separation belt 55 is extremely reduced, and the spring 27
Is adjusted so that the movable plate 57 holding the first support roller 53 can be raised in the direction of the arrow Y1.

Accordingly, in the form taking-in mechanism 51 configured as described above, when the form 82 is not taken into the apparatus (when the sheet is not fed), the first and second forms are taken as shown in FIG. The second support roller 54 is moved by an arrow C by the motor 56 so that the separation distance between the support rollers 53 and 54 becomes almost maximum.

3 can be lowered in the direction of arrow Y2 to separate the separation belt 55 from the feed roller 4, and the separation belt 55 can be slightly rotated in the direction of arrow C. In the optical character reading device of the present embodiment, such operation control suppresses local wear of the separation belt 55 and extends the life of the separation belt 55.

On the other hand, when the form 82 is taken into the apparatus (at the time of paper feeding), as shown in FIG. 10, the separation distance between the first and second support rollers 53 and 54 is substantially minimized. To
The second support roller 54 is eccentrically driven in the direction of arrow C by the motor 56. Thereby, the first support roller 53 can be raised in the direction of the arrow Y1 and the separation belt 55 can be brought into contact with the feed roller 4, and the separation belt 55 can be slightly rotated in the direction of the arrow C. The separation belt 5 thus contacting the feed roller 4
