せしめることになる。(Problems to be Solved by the Invention) However, the above-mentioned prior art poses a particular problem when applied to an apparatus that processes paper sheets of different lengths, as the leading edge of the paper sheet may be pinched by the conveying means. Even in the case where the second half of the sheet is on the side of the stacked sheet group from the gate section, the distance between the conveyance means entrance and the gate section must be much larger than the minimum length of the sheet in the feeding direction. considered small. On the other hand, if the length of the outer circumferential surface of the endless belt is a long dimension corresponding to the paper sheet having the maximum length in the feeding direction, in the driven feeding position, the gate part, the conveying means entrance, the banding force applying means or the posture holding means The bending of the endless belt formed between the three parts becomes extremely large, and the bending cannot be accommodated between the above-mentioned distance between the conveyance means entrance and the gate part, which impedes the feeding operation. Therefore, the length of the outer peripheral surface of the endless belt is set to be shorter than the length in the feeding direction that corresponds to the maximum length of paper sheets. In that case, when paper sheets with a large length in the feeding direction are fed out, the deflection that occurs between the gate part and the banding force applying means or the posture holding means becomes maximum in the driven feeding posture, and the maximum deflection state remains for a long period of time. Subsequently, abrasion occurs due to the speed difference between the endless belt and the belt motion imparting means, and both are likely to wear out, resulting in a significant deterioration of durability.

なる。When the uppermost paper sheet P is further fed out, the lower surface of its leading edge first reaches the guide member 25, and is held between the endless belt 7 above the leading edge (note that the sheet to be processed If the thickness is intermediate, it is guided in a state close to being held) and hits the gate member 24, and then its tip is between the gate rollers 24A, 24A forming the gate member 24 and the endless belt 7. and pushes this gate member 24 downward. As a result, the swing block 28 constituting the support means 26 of the gate member 24 is rotationally displaced in the counterclockwise direction in FIG. It is swung integrally with the guide member 25, and the leading edge of the paper sheet is attached to the guide member 25.
The gate member 24 is held between the endless belt 7 and the endless belt 7.
is pushed and moved, only one sheet P enters between the gate member 24 and the endless belt 7 without bending the leading edge of the sheet, and the second and subsequent sheets are fed. The class P is placed with its tip abutting against the circumferential surface of the gate member 24 and the guide member 25 (as shown in the fourth figure). In particular, the gate rollers 24A, 24A serving as the gate member 24 are not rotated in the paper sheet delivery direction and are in a non-rotatable state, so that the movement of the second and subsequent paper sheets P is reliably prevented. .

1, the paper sheet P is being fed out, but when it reaches the state shown in FIG. 5, it will be transformed into the driven feeding posture. In other words, when the leading edge of the paper sheet P is securely caught between the belts 34 and 35, the belt 34 and 35 rotate at a circumferential speed of υ2 in the direction of the arrow, which is faster than the feeding speed of the endless belt 7, υ1. The paper sheets P are pulled at a speed υ2, and the lower part 7B1, in which the endless belt 7 has become slack, is pulled by the paper sheets P and moved at a moving speed υ2 of the paper sheets P, and 7B, the amount of slack decreases by the speed (υ2-υ1)■, and the belt portion 7B2 (the endless belt 7 portion between the gate member 24 and the pulley 14) on the side facing the conveyance mechanism 17 of the rotating body 8 increases the speed.

側位置のベルト部分）に生じるたるみは最大となる。When the rear end of the paper sheet P pulled by the conveyance mechanism 17 comes off the detection lever 22 (FIG. 7), the detection lever 22 rotates counterclockwise under its own weight, and the top surface of the next paper sheet P The base end 22A of the detection lever 22 turns off the sensor S and operates, and a detection signal is input from the sensor S to the control unit C. The motor M2 is activated through the control unit C, and the pedestal 2 is turned off again. The upper surface of the next paper sheet P after the paper sheet P to be fed out pushes up the detection lever 22 and touches the base end 22A of the paper sheet P.
When the sensor S is switched on and activated, the motor M2 is stopped through the control unit C, and the lifting of the pedestal 2 is also stopped (as shown in the eighth figure). As a result, the next paper sheet P after the paper sheet P to be fed out is at a height position in preparation for feeding, that is, a height position at which the return posture of the endless belt 7 formed after that should be a drive feeding posture appropriate for feeding. In other words, there is no slack in the belt portion 7B2 of the endless belt 7, and the belt portion 7B
Deflection occurs only in belt 1, and belt portion 7B of endless belt 7
The deflection of 1 is located at a height position where the deformed posture is appropriate for feeding. In addition, in Fig. 8, the delivered paper sheet P
Although the rear end is still in contact with the endless belt 7, the lower part 7B1 of the endless belt 7 has almost no slack and is in a y-tensioned state, and on the way from FIG. 8 to FIG. 9, the lower part 7B1 of the endless belt 7 The slack in the side portion 7B1 is completely eliminated and becomes a tensioned state, and the slack generated in the belt portion 7B2 (the belt portion on the right side of the rotating body 8) is maximized.

移動する。The period in which slack exists only in the belt portion 7B2 of the endless belt 7 (the belt portion on the left side of the rotating body 8, that is, the belt portion between the gate member 24 and the pulley 14) is shown in FIGS. 8 to 9. This period is from the time when the trailing end of the delivered paper sheet P passes through the gate gap between the gate member 24 and the endless belt 7 (the intermediate time between FIG. 9 and FIG. 10). Until that period, the amount of slack in the belt portion 7B2 of the endless belt 7 is increasing, so the belt portion of the endless belt 7 that contacts the belt 15 is moving at the same speed as the speed υ1 of the belt 15. . However, during the above period (a period in which only the belt portion 7B2 of the endless belt 7 has slack), the belt portion 7B2 of the endless belt 7 moves at a speed υ2 through the paper sheet P, and the belt portion 7B1 of the endless belt 7 and the roller 18, 19,
Since the belt portions at the pulley 13 position are under tension, these belt portions are also moved at a speed υ2, and belt 1
There is a speed difference (
A tensile force of υ2-υ1) is applied, and as a result, the belt 15, which was being driven at a speed υ1, is moved to the speed increasing side between the pulley 13 and the driving shaft 11 via the freely rotating one-way clutch 16. The speed changes to υ and moves at that speed υ2.
その結果、その期間中は無端ベルト７のすべての部分が

A tensile force of a speed difference (υ2 - υl) is applied to the belt portion of the endless belt 7 that is in contact with the belt 15 during the entire period during which the paper sheet P
In the case of processing large length items, the period becomes long, causing repeated expansion and contraction of the endless belt 7 and belt 15, wear between both belts, etc., which shortens the life of both belts. Become. The one-way clutch 16 is provided to solve this problem.
