摘要： PURPOSE:To accurately detect a magnetic inductor from an electric amount generated due to an electromotive force of a coil by energizing a coil to generate a magnetic field between the coil and a detecting place, and then stopping the energization of the coil. CONSTITUTION:When a control signal to be input from a terminal 28 to a base of a transistor 25 becomes a low level, the transistor 25 turns on, and a current flows from a power source 26 to a coil 21. Thus, a magnetic field is generated between the coil 21 and a detecting place 22. When the signal from the terminal 28 is set to a high level as a current flowing to the coil 21 becomes stable, the transistor 25 is interrupted, and the energization of the coil 21 is stopped. Therefore, the current of the coil 21 is gradually decreased. The decrease in the current becomes slow, the larger an inductance of the coil 21 is. When a magnetic inductor 23 is disposed at the detecting place, the inductance becomes larger than that when the inductor 23 is not disposed, and an electromotive force of the coil 21 is also increased. Accordingly, presence/absence of the inductor 23 can be detected from a length of a time in which a diode 27 is conducted by the electromotive force of the coil 21.

摘要： PURPOSE:To conduct jogging operation one pin by one pin and efficiently execute paper neat arrangement. CONSTITUTION:Sheets are sorted and distributed to a plurality of bins 350. When the sheets are neatly arranged, the sheets are pressed from one side end part to the other side end part side by the jogger plate 501 of a jogger unit 500, and the movement of the other side end part of the sheets are regulated by a side fence shaft 40, whereby the cross directional paper arrangement is conducted between the jogger plate 501 and the side fence shaft 401. When the sheet is discharged to the bin 350, the rear end part of the sheet makes contact with the raised part 500 on the rear end of the bin 350, the position of the sheet is regulated in three points, and sure paper arrangement is executed. At this time, a moving jogger part is moved every bin, and the jogger plate 501 is operated to neatly arrange the sheet.

摘要： PURPOSE:To perform the alignment and conveyance of paper without fail by installing a conveyor roller, having a yet tardier feed rate and preventing any overspeediness of the paper, in a skewing conveyor roller which makes a paper end contact with a guide member installed in a paper conveying passage. CONSTITUTION:A sheet of paper P conveyed to a space between guide plates 1, 2 opposed to each other is sent in the A direction through paired conveyor rollers 3, 4. When the rear end comes off these paired conveyor rollers 3, 4, it is obliquely conveyed by each of skewing conveyor rollers 13-16 set up aslant in the specified angle B direction, and then it hits on guide members 17, 18 and is sent in the A direction again, thus it is carried out to an after-treatment part by conveyor rollers 5, 6. At this time, the paper P comes into contact with ball rollers 10-12 driven in rotation and goes forward rectilinearly, but its overspeediness is prevented by guide rollers 7-9 rotating at a slower feed rate than the skewing conveyor rollers 13-16. Thus, end face alignment conveyance is surely performed.

摘要： PURPOSE:To quickly dissolve buckling condition and the like of transfer paper by providing an energizating means to energizate pulleys in up and down movable condition. CONSTITUTION:A transport belt 101 is pushed up against the energizating force of a spring 107 due to contact of a cam member 302 with transfer paper 401, and when the cam member 302 is separated from the transfer paper 401, the cam member 302 and the transport belt 101 are likely to temporarily separate from the transfer paper 401. In this case, the buckled transfer paper 401 is recovered the original condition due to stiffness of itself, hereafter again, the transport belt 101 is contacted with the transfer paper 401 by the energizating force of the spring 107, and transport operation of the transfer paper 401 in the prescribed direction is repeated. Name, by intermittent pushing up motion of the transport belt 101 with the cam member 302 accompanied with rotational movement of a pulley 102 with cam, buckling condition of the transfer paper 401 is dissolved.

摘要： PURPOSE:To reduce the number of parts required so as to allow the cost to be reduced by allowing only a delivery means to rotate either normally or reversely through both No.1 and No.2 one way clutches. CONSTITUTION:With a drive motor rotated normally, a drive shaft 18 is rotated through a worm gear 25. This causes both a paper feed output gear 19 and No.2 delivery output gear 22 to rotate to the direction X1 as shown by an arrow head through No.1 one way rotary clutch C1 and C2 permitting both a paper feed input gear 17 and a separation gear 15 to rotate to the direction X2 as shown by an arrow head, also permitting a separation roller 7 to rotate to the direction 'b' as shown by an arrow head. This causes each of paper feed pulleys 3 and 4 to rotate to the same direction through each of shafts 3a and 4a permitting a paper feed belt 6 to rotate to the direction 'a' as shown by an arrow head, also permitting a drive roller 10 to rotate to the direction 'c' as shown by an arrow head. Besides, when a sensor S is activated allowing the motor 24 to rotate reversely, the worm gear 25 is rotated to the direction Y as shown by an arrow head allowing only No.1 delivery output gear 21 to rotate to the direction 'y1' as shown by an arrow head through No.2 one way rotary clutch C2 continuing delivering through a shaft 10a of a delivery means B'.
