Abstract

PURPOSE:To prevent a paper from coming off a paper-separating member from a corner part thereof and being fed out in an inclined condition, by a construction wherein a bending range restricting member elongate in the width direction of a paper is provided in the vicinity of feeding-out rollers. CONSTITUTION:In a paper-supplying device, a plurality of feeding-out rollers 2a, 2b, 29 fitted to a common shaft 60 are brought into contact with the uppermost one 4 of a multiplicity of papers tacked in a paper-holding part, and the uppermost paper 4 is fed out by rotating the rollers. In this case, both corner parts of the paper 4 are bent by bringing into contact with a left-right pair of paper- separating members 3a, 3b, 32, whereby only the upper most paper 4 is fed out. In the device, the bending range restricting member 82 elongate in the width direction of the paper is provided in the vicinity of the rollers 2a, 2b, 29. Accordingly, even where papers of different paper widths are contained in the paper- holding part and the width of the separating member is adjusted while the width between the rollers is not adjusted so that the spacing between the roller and the separating member on the left side is different from that on the right side, the paper can be prevented from skewing.

のが知られている。[Technical background of the invention] As an automatic paper feeder, a large number of papers are fed into a paper holding section fF.
There is a known structure in which the paper in the paper holding section is sent out one by one from the top to a predetermined paper processing section by holding the I layer and bringing a delivery roller into contact with the uppermost paper surface and rotating it in a fixed direction. ing.

They are usually arranged in an axial direction. This is because if one long roller is used, it is difficult to equalize the contact pressure against the paper over the entire length, and if the contact pressure is not even, the paper may run skewed. Due to reasons such as aiming for

The paper 4 moves in the direction of arrow B due to the contact resistance between them. However, the left and right corners of the paper 4 are separated by the paper separation member 3.
a, 3b, the uppermost sheet is deflected 4a between the feed roller 2a and the separation member 3a, and between the feed roller 2b and the separation member 3b as shown in FIG.
occurs (only one is shown, but the same applies to the other), and the movement of the second and subsequent sheets is prohibited by the female members 3a and 3b. When the deflection 4a increases to a certain extent, both corners of the paper 4 are finally separated from the separation members 3a and 3b, and the uppermost paper 4 is sent to a predetermined paper processing section (for example, the printing section of a printing device). Become.

するおそれがあるのである。On the other hand, it is desirable that the paper holding section be capable of holding not only papers of a fixed size but also papers of different sizes (particularly width dimensions). Therefore, one separating member 3a is fixed at a fixed position, and the other separating member 3b is movable and adjustable according to the paper width. However, if only the separation part (No. 3b) is moved but the paper feed roller is not moved, the distance between the separation member and the feed roller will be different on the left and right, and the range of the deflection 4a will be different on the left and right.In other words, for example, the distance between the paper feed roller on the right side will be different. When the distance between the roller 2b and the separating member 3b becomes larger than the distance between the left delivery roller 2a and the separating member 3a, the sheet 4 is deflected over a wide range 4a on the right side, and the corners of the sheet 4 are bent by the separating member. As a result, the leading edge of the paper 4 may tilt to the right and travel obliquely.

［背景技１ｆｉの問題点］ しかしながら、このように回転軸１ンの外周や、送出し

Therefore, it is undesirable.

を組込む理由は次の通りである。Moreover, in a configuration in which the delivery roller 12 is kept in contact with the paper surface at all times, it is necessary to incorporate a one-way clutch between the rotating shaft 1r and the delivery roller 2t. It becomes even more complicated. The reason for incorporating the one-way clutch is as follows.

せる必要がある。In other words, it has been conventional practice to use the paper feed drive source of the paper supply destination as the drive source for rotating the paper feed roller, for example, if it is a paper feed device that supplies paper to a printing device, the drive source of the printing device has been used. ing. In this case, the paper feeding row on the paper feeder side feeds the paper to the position where it reaches the paper feeding mechanism of the paper feeding destination, and the paper is delivered to the paper feeding mechanism of the paper feeding destination, and then the paper is fed by the paper feeding mechanism of the paper feeding destination. It will be done. Therefore, the paper feeding on the feeding device side is stopped at the same time as the paper feeding mechanism of the paper feeding destination starts the paper feeding operation, and
It is necessary to prevent the sheets of paper from being sent out consecutively. For this reason, the paper feed roller attachment mechanism of the paper feed device is such that the paper feed roller is attached via a one-way clutch to a rotating shaft that rotates in conjunction with the paper feed mechanism of the paper supply destination as appropriate, and the paper is loaded from the paper holder. When feeding, the rotation shaft is rotated and the rotation is transmitted to the paper feed roller. After the paper is delivered to the paper feed mechanism at the paper feeding destination, the paper feed roller is rotated so as not to interfere with the paper feeding operation of the paper feed mechanism. It is necessary to rotate the motor idly relative to the rotation axis.

発生の原因ともなる問題があった。In addition, in order for the delivery roller to move smoothly in the axial direction, it is necessary to provide a certain amount of clearance between the core tube of the delivery roller and the rotating shaft. Swinging with respect to the rotating shaft is unavoidable, and there is a problem in that such swinging of the feed roller causes skewing when feeding the paper.

The paper holder is rotated integrally with the rotating shaft by bringing the respective outer circumferential surfaces into simultaneous contact with the uppermost sheet surface which is arranged and attached to the rotating shaft and held by the paper holder. a plurality of delivery rollers that send out the uppermost sheet of paper held by the paper holder, at least one of which is movable in the width direction of the paper, and both corners of the paper held by the paper holding unit on the delivery side are brought into contact with each other; The reason why both corners of the uppermost sheet of paper are bent between it and the feed roller located at the end is the pair of paper separation members that send out only the uppermost sheet of paper, leaving behind the second sheet of paper. A corner portion of the uppermost sheet of paper that is disposed in the vicinity of the delivery roller and long in the paper width direction so as to be close to the paper surface of the uppermost paper sheet held by the paper holding section, and that is located at a corner of the uppermost paper sheet when the delivery roller rotates. and a deflection range regulating member that regulates the deflection range of the deflection range. In other words, by arranging a deflection range regulating member that is long in the paper width direction near the feed roller, the deflection range of the corner of the paper does not widen even if the paper separation member moves away from the feed roller. This allows the paper to be easily removed from the paper separating member, thereby preventing the paper from being skewed.

バー６５を選択的に係合させるように構成されている。As shown in FIG. 4, the feed roller 29 is driven by a motor 49 provided within the printing device 11 for driving the platen 15. That is, the rotation of the motor 49 is transmitted to the platen 15 via a motor gear 50, an intermediate gear 51, and a platen gear 52. Meanwhile, the mounting base 14 is provided with gears 53 and 54 that mesh with the platen gear 52 in series, and the main body frame 13 is provided with gears 55, 56, 57, and 58 that mesh with the gear 54 in sequence.
is provided. A spring clutch mechanism 59 (see FIG. 5) is provided coaxially with the gears 58. The configuration of this spring clutch 1 geometry 59 is explained in the fifth section.
To explain with the drawing, a sleeve 58'a integral with the gear 58 is rotatably fitted to one end of a rotating shaft 60 which is rotatably supported by the main body frame 13 and has the delivery roller 29 attached thereto. A clutch spring 61 is mounted on the outer periphery of 58a, and a cylindrical body 62 is mounted on the outer periphery of the clutch spring 61.
and locking one end 61a of the clutch spring 61 to the inner periphery of this cylindrical body 62. At the same time, a cap 63 is fixed to one end of the cylindrical body 62, and the cap 63 and the rotating shaft 60 are connected to each other by attaching the bottle 64. The claw levers 65 are connected so as to rotate integrally through the cylindrical body 62, and the claw levers 65 are selectively engaged with protrusions 62a provided on the outer periphery of the cylindrical body 62.

るとき両角部に第９図の如くたわみ部２６ａが生しる。First, in order to automatically feed paper to the printing device 11, the switching operation member 42 is set up as shown by the solid line in FIG. In this case, the tip of the movable guide 40 rises above the internal fixed guide 38, and the second paper discharge guide 40a of the movable guide 40 comes to be continuous with the first paper discharge guide surface 381]. The outer opening of the paper path 39 is closed by the tip of the movable kite 40. Further, the paper holding section 25 holds a predetermined number of sheets 26 in a stack, and a spring 28 presses the uppermost sheet surface against a delivery roller 29 . In this state, when the electromagnet 67 is energized and the motor 49 is started, the rotary shaft 60 rotates together with the platen 15, and the rotation of the rotary shaft 60 is transmitted to the delivery roller 29 via the clutch spring 79. Then, the feed roller 29 rotates in the direction of the arrow in FIG. It moves from the holding part 25 in the sending direction. At this time, since both corners of the rf1 paper T and the paper 2G in the h section 25 are in contact with the left and right paper separation members 32 on the sending side, the uppermost paper 26 is not moved in the sending direction. When this is done, bends 26a are formed at both corners as shown in FIG.

Then, the paper 2 sent out from the paper storage 1j section 25
After passing through the paper path 20, the paper sheet 6 is inserted between the paper pan 16 and the kite member 24, and further guided between the platen 15 and the pinch roller 17a. At this point, the power to the electromagnet 67 is cut off, and the rotation of the rotating shaft 60 is stopped. Thereafter, the paper is further fed by the rotation of the platen 15 itself, or at this time, the feed roller 29 idles around the rotating shaft 60, so that the movement of the paper 26 is not hindered. In this manner, the paper 26 is wound around the platen 15, and predetermined printing is performed by printing (not shown). Then, the printed paper 26 passes between the platen 15 and the hale roller 18 (however, the hale roller 18 is once separated from the platen 15 to facilitate the passage of the paper 26), and passes between the external fixed guide 23 and the internal It is guided between the fixed guide 38 and the fixed guide 38 . Furthermore, the first paper ejection guide surface 3 of the internal fixed guide 38
3b, the sheet rises to the second sheet ejection guide surface 40a continuous thereto, is held between a pair of sheet ejection rollers 46a and 4611 that rotate simultaneously with the platen 15, and is received into the stocker 47 by their rotation.

備したことを特徴とする自動給紙装置。(2) A paper holder capable of stacking and holding papers of various widths, a rotating shaft disposed in the width direction of the paper facing the paper stacking surface of the paper holder, and a rotating shaft that is arranged and attached to this rotating shaft. The uppermost sheet held in the paper holding section is rotated together with the rotating shaft while avoiding simultaneous contact of the respective outer circumferential surfaces with the surface of the uppermost sheet held on the sheet holding section, thereby transferring the uppermost sheet held on the sheet holding section to a predetermined paper processing section. A plurality of feed rollers, etc., are disposed on the paper stacking surface side of the paper holding section, and are arranged at a predetermined paper processing section J.
, a stocker for receiving processed paper ejected from the paper, and a stocker, at least one of which is movable in the width direction of the paper, so that both corners of the paper held in the paper holding section on the feeding side are brought into contact with each other, and the paper stocker located at the end thereof The reason why both corners of the uppermost sheet of paper are bent between the feed rollers is that a pair of paper separation members are formed integrally with the stocker and are integrally formed with the stocker to send out only the uppermost sheet of paper, leaving behind the second sheet of paper. located in the vicinity of the delivery roller and disposed long in the paper width direction in close proximity to the uppermost paper surface held by the super-holding section;
An automatic paper feeder comprising: a deflection range regulating member that regulates a deflection range of a corner of the uppermost sheet when the feed roller rotates.
