It is configured to determine the storage position of each inside. Therefore, by applying the present invention, the mechanical structure of the form sorting mechanism can be significantly simplified.

〔Example] EMBODIMENT OF THE INVENTION The present invention will be described in detail below based on embodiment figures.

Figures 1 (al and (bl) are a schematic side view and a schematic perspective view of essential parts showing one embodiment of the present invention, Fig. 2 is a block diagram showing the configuration of the present invention, and Fig. 3 is a discharge sensor. 4 is a waveform diagram showing the relationship between the operation timing and the change timing of the form sending speed, in which the same parts as in FIG. 4 are given the same reference numerals.

As shown in FIGS. 1(a) and 1(bl), in the form sorting mechanism according to the present invention, the form 1 is transferred from the form transport section 20 to the stacker 15.
A form ejection sensor 3 detects whether the ejected form 1 is ejected to the side, and a form delivery roller 5 sends out the ejected form 1 to the stacker 15 side depending on whether the ejected form 1 is a normal form IA or a defective form IB. a control unit 10 that changes the rotational speed of the form L that is sent out from the form sending roller 5;
A form sorting means (hereinafter referred to as a form sorting means) determines a storage zone for normal forms IA and defective forms IB (hereinafter referred to as forms 1 when there is no need to distinguish between them) in the stacker 15 in accordance with the feeding speed of It is equipped with 7 (called a board). In the figure, reference numeral 4 denotes a document guide that guides the document l toward the document sending roller 5 side, 15a and 15b indicate a normal document storage zone and a defective document storage zone, which are separated by the document selection plate 7 provided in the stacker 15; is form sorting board 7

This form sorting mechanism is configured to handle the form l which is conveyed in the direction of arrow F on the form transport unit 20 and sent to the form sending roller 5.
When the form I is a normal form IA, the form sending roller 5 rotates at a constant speed, and when this form I is a defective form IB, the form sending roller 5 rotates at a high speed.

In this manner, the form sorting mechanism controls the flying force of the form 1 sent out from the form sending roller 5 by changing the rotational speed of the form sending roller 5, and controls the flying force of the form l to control the flying force of the form 1. It is characterized by a structure in which the document is stored in a normal document storage zone 15a located directly below the document sending roller 5, or in a defective document storage zone 15b located in front of the normal document storage zone 15a. .

This form sorting mechanism is configured to separate storage zones for normal forms IA and defective forms IB by differentiating the flying force of form 1, so two form storage zones (normal form storage zones) are created on the same plane. zone 15a and defective form storage zone 15b), the stacker 1
5 is significantly simplified. Note that in this example,
Although the normal form storage zone 15a is arranged directly below the form sending roller 5 and the defective form storage zone 15b is arranged in front of the normal form storage zone 15a, it is of course possible to reverse this arrangement.

However, in that case, it is necessary to control the sending speeds of the normal form IA and the defective form IB in a manner opposite to that of the embodiment described below.

The operation of this form sorting mechanism will be explained in more detail below using FIGS. 1(a) and 1(b).

(1) When @ Form 1 is a normal form LA ■ When the form discriminating unit 60 notifies the control unit 10 that the form l being conveyed is a normal form IA, the control unit 10 stores this information in the memory. Wait until the form 1 is completely ejected from the form transport section 20.

(2) When it is confirmed by the information from the ejection sensor 3 that the form 1 has been completely ejected from the form transport unit 20, the control unit 10 causes the ejection motor 30 that drives the form delivery roller 5 to continue rotating at a constant speed. A command is issued. Therefore, the form sending roller 5 continues to rotate at a constant speed.

(2) The form 1 (normal form IA) sent to the form sending roller 5 via the form conveyance section 20 is sent to the stacker 15 side by the form sending pressure roller 5 rotating at a constant speed. However, since this normal form IA is sent out by the form sending roller 5 rotating at a constant speed, it has poor flying power. Therefore, this normal form IA immediately falls in the direction of the arrow α and is accommodated in the normal form storage zone 15a provided on the front side of the stacker 15.

(2) When the form 1 is a defective form IB O) When it is confirmed by the information from the form discrimination unit 60 that the form 1 being transported is a defective form IB, the control unit 10 stores this information in the memory. and waits until the form l is completely discharged from the form transport section 20.

(2) When it is confirmed by the information from the ejection sensor 3 that the form 1 has been completely ejected from the form transport unit 20, the control unit 10 causes the ejection motor 30 that drives the form delivery roller 5 to rotate at high speed for a certain period of time. An order is issued to do so. The timing at which the form sending roller 5 rotates at high speed is counted by a clock section 9 disposed within the control section 10. The second clock section 9 regulates the time during which the form sending roller 5 should rotate at high speed, and for example, a timer or the like is used.

(2) When the form 1 (defective form IB) is sent to the form sending roller 5, the defective form IB is given a flying force by the form sending roller 5 rotating at high speed and flies in the horizontal direction. Then, when it jumps over the form sorting plate 7, it loses its flying power and falls in the direction of the arrow β to a defective form storage zone provided in front of the normal form storage zone 15a (a position away from the form sending roller 5). It is accommodated in 15b.

(2) When the defective form IB has been sent out, the timer 9 acts, the discharge motor 30 returns to constant speed rotation, and the form sending roller 5 also returns to constant speed rotation.

FIG. 2 is a block diagram showing the configuration of the present invention.

As shown in FIG. 2, this form sorting mechanism determines the rotational speed of the form delivery roller 5 based on the form information sent from the form discrimination section 60 and the position information of the form l sent from the discharge sensor 3.

It is equipped with a form sorting board 7 that determines the Note that the operation of each of these components is as described above.

t2 is the time when the leading end of the form 1 is detected by the ejection sensor 3, t2 is the time when the rear end of the form 1 is detected by the ejection sensor 3, and the ejection motor 30 starts rotating at high speed, and t3 is the high speed rotation. The points at which the discharge motor 30 returns to constant speed rotation are shown.

As shown in FIG. 3, this form sorting mechanism changes the rotation speed of the ejection motor 30 when the rear end of the form 1 is detected by the ejection sensor 3, and the form I is transferred to the form sending roller 5.
The rotational speed of the discharge motor 30 returns to the original speed at the time when the discharge is finished. This is form 1
If the rotational speed of the form delivery roller 5 changes before the form has been completely sent out from the form conveyance section 20, the form l may be pulled or loosened due to this change in form conveyance speed, causing the form l to
This is to avoid the possibility of damage. Note that t1 to t2 are based on information from the discharge sensor 3,
