In the conventional automatic paper feeding device of a diazo copying machine, a locking pawl is provided at the tip of the photosensitive paper container, and this locking pawl is always pressed against both ends and both corners of the top surface of the stacked photosensitive paper. This prevents multiple sheets of photosensitive paper from being fed out together in a pile.

A type of copying machine that uses such a locking pawl to prevent two-sheet feeding has two methods: (1) As the amount of photosensitive paper decreases, the locking pawl is successively pushed down by its own weight, A type that always applies appropriate pressure to both ends and both corners of the top surface,
(11) The locking pawl is fixed, and as the amount of photosensitive paper decreases, the photosensitive paper mounting plate on which the photosensitive paper is placed is raised in an almost horizontal state using a compression spring, etc., and the locking pawl is raised. (110) is a type that applies appropriate pressure between the photosensitive paper and the photosensitive paper. ), the photosensitive paper mounting plate is not raised in a horizontal state, but is of the type that swings the photosensitive paper mounting plate using its rear end as a fulcrum in the photosensitive paper transport direction, for example, 54-65971, etc.

The reason for this is that as the amount of photosensitive paper placed on the paper decreases during copying, the top surface of the photosensitive paper gradually becomes lower, which changes the transport length to the point where the photosensitive paper and original meet. As a result, the overlapping position between the leading edge of the photosensitive paper and the leading edge of the document becomes unstable, which tends to cause misalignment of the leading edges of the two.
In addition, the horizontal and vertical contact positions between the photosensitive paper feeding port roller and the top surface of the photosensitive paper change, which may cause two sheets of photosensitive paper to be fed. This is because, since the photosensitive paper is forced to come into contact with the locking pawl, the leading corner of the photosensitive paper is bent and sent out, which may cause a paper jam. The model (1:) above raises the photosensitive paper horizontally, so it
), the drawbacks due to variations in the horizontal and vertical contact positions between the photosensitive paper feed roller and the uppermost photosensitive paper do not occur, but the photosensitive paper loading plate is usually raised by a compression spring. The pressure between the uppermost surface of the photosensitive paper and the locking claw varies depending on the amount of photosensitive paper placed, that is, its weight, which may cause two sheets of photosensitive paper to be fed or the tip angle of the photosensitive paper to change. Sometimes the parts are folded and sent out.

In this sense, it is not necessarily preferable that the uppermost surface of the photosensitive paper and the locking claw come into contact with each other. In addition, since such a mechanism usually uses 2 to 6 springs, the photosensitive paper mounting plate will not be horizontal due to the extremely slight difference in the repulsive force of each spring, and this will cause the photosensitive paper to be placed on an uneven surface. There is a drawback that the pressure balance between the uppermost surface of the paper and the locking pawl is disrupted, or the contact pressure between the uppermost surface of the photosensitive paper and the photosensitive paper feed roller becomes uneven, resulting in diagonal feeding of the photosensitive paper. In order to avoid this drawback, a method has already been proposed in which the photosensitive paper is mechanically raised as the paper decreases, without using something like a spring, but the device becomes large and expensive. Unfavorable in some respects. The above model (111) has a relatively simple structure and can be manufactured at the lowest cost, and the pressure between the top surface of the photosensitive paper and the locking claw is always constant regardless of the amount of photosensitive paper. A switch means is provided to gradually change the inclination angle of the photosensitive paper mounting plate in accordance with the amount of photosensitive paper placed on the photosensitive paper mounting plate.

In this type of paper, the top and bottom positions of the leading edge of the photosensitive paper and the top edge of the photosensitive paper are kept virtually unchanged regardless of the amount of photosensitive paper, which prevents double-sheet feeding and diagonal feeding of the photosensitive paper. It is also important to align the leading edge of the original with the leading edge of the photosensitive paper before transporting it to the main storage of the copying machine. The amount of variation in the position of the top surface of the photosensitive paper due to the amount of paper placed on the paper is significant.In other words, the smaller the amount of photosensitive paper placed on the paper, or the further the rear end of the photosensitive paper is, the more the top surface of the photosensitive paper changes. There is a significant difference between the vertical position of the photosensitive paper and the position of the top surface of the photosensitive paper when the maximum amount is loaded. Therefore, in order to keep the leading edge of the photosensitive paper at a substantially constant position in the vertical direction, the photosensitive paper is placed on the photosensitive paper placement plate in accordance with the consumption amount of the photosensitive paper placed on the photosensitive paper placement plate. Most ideally, the switch means for instructing to raise the plate should be located near the leading edge of the photosensitive paper. However,
If the photosensitive paper feed roller is not brought into contact with the leading edge of the photosensitive paper as much as possible, it will cause diagonal feeding or double sheet feeding.
In addition, if you want to match the leading edge of the original with the leading edge of the photosensitive paper before conveying it to the copying machine, the discrepancy between the leading edges may occur due to the change in the contact position between the photosensitive paper feed roller and the photosensitive paper. For this reason, it is often difficult to provide the switch means near the leading edge of the photosensitive paper from the viewpoint of securing installation space. In such a case, that is, when the switch means must be located between the leading edge and the trailing edge of the photosensitive paper due to space restrictions on the installation position of the photosensitive paper, as described above, A switch means for instructing to raise the photosensitive paper mounting plate is positioned at a portion where the vertical position of the uppermost photosensitive paper changes significantly depending on the amount of photosensitive paper placed due to the tilting of the mounting plate. However, in order to keep the vertical position of the leading edge of the photosensitive paper substantially constant at all times, it is necessary to move the above-mentioned switch means in response to fluctuations in the vertical position of the top surface of the photosensitive paper. Moving the switch means unnecessarily complicates the apparatus, and it is also extremely difficult to keep the vertical position of the leading edge of the photosensitive paper substantially constant at all times. Therefore, the main object of the present invention is to maintain the vertical position of the leading edge of the top surface of the photosensitive paper almost constant regardless of the amount of photosensitive paper, and to smoothly and smoothly move the photosensitive paper one by one from the photosensitive paper container along the conveying path. An object of the present invention is to provide an automatic paper feeding device for a copying machine that reliably supplies paper.

When the document insertion table 18 is opened and relatively large and heavy photosensitive paper 6 of, for example, A3 or B4 size is loaded in the photosensitive paper container 40, the operating rod 100 is inserted into the locking notch 104.
to be locked. When the document insertion table 18 is closed as shown in FIGS. 1, 3, and 4, the actuating piece 92
The movable plate 82 is rotated counterclockwise around the shaft 80 by. Therefore, the strip 110 is tensioned by the spring 106 with a relatively large elastic force. At this time, pulley 78
A counterclockwise elastic torque acts on the rotation shaft 72, and the lift lever 64 elastically raises the front end of the photosensitive paper mounting plate 44 accordingly. Therefore, the uppermost surface 6a of the photosensitive paper
is elastically pressed against the paper feed roller 74. In this state, the lower surfaces of the top portions 52a, 54a of the two-type city nails 52, 54 maintain a state in which they are close to the tip of the uppermost surface 6a of the photosensitive paper without being substantially pressed against it. The pressing force between the uppermost surface 6a of the photosensitive paper and the paper feed roller 74 is determined by the elastic force of the spring 106, and the spring constant of the spring 106 is set to an optimum value so that this pressing force can reliably feed only one sheet of photosensitive paper. The value is preselected. When the document insertion table 18 is opened as shown by the imaginary line in FIG.
2 clockwise rotation is allowed.

Therefore, the band plate 110 is loosened, and the pulley 78, rotation shaft 72, and lift lever 64 can freely rotate clockwise.
Therefore, as shown in the third diagram, the spring 106 is in a tensioned state.
loosens as shown by the imaginary line 106a in FIG. Accordingly, the photosensitive paper 6 and the photosensitive paper mounting plate 44 are lowered by their own weight,
The pressure contact between the uppermost surface 6a of the photosensitive paper and the paper feed roller 74 is broken. Therefore, the photosensitive paper container 40 can be easily removed from the machine body 2. The photosensitive paper 6 is, for example, A4 or B.
If it is relatively small and lightweight like 5,
As shown in FIG. 5, the operating rod 100 is locked in the locking notch 105.

Therefore, the strip 110 and therefore the pulley 78 have a spring 1
08 exerts a relatively small elastic force. Therefore, the lift lever 64 pushes up the photosensitive paper mounting plate 44 and transfers the uppermost surface 6a of the photosensitive paper to the paper feed roller 74 using the optimal force to ensure that only one sheet of photosensitive paper is fed without having to feed two sheets of photosensitive paper. Press with the appropriate pressure. In this way, depending on the weight of the photosensitive paper 6,
Since the pressure contact force between the uppermost surface 6a of the photosensitive paper and the paper feed roller 74 is maintained at the optimum value for feeding the photosensitive paper, feeding of two sheets of photosensitive paper is prevented and only one sheet is reliably fed. According to the idea of the present invention, the top portions 52a, 54a of the locking claws 52, 54
There is a small distance between the bottom surface and the tip of the top surface 6a of the photosensitive paper 6 placed on the photosensitive paper mounting plate 44, so that they do not come into contact with each other, or even if they do, they contact with very little pressure. This is important, and compared to the conventional case where the contact pressure is relatively large, according to the present invention, feeding of two sheets of photosensitive paper 6 is prevented as shown in Table 1 below.

FIG. 10 shows a state where the original is not being conveyed. One contact 128a of the detection switch 128 is connected in series with the relay 222, and the other contact 128b is connected in series with the relay switch 224 of the relay 222 and the rectifier circuit 226. A capacitor 228 is connected in parallel to the relay 222 . The electromagnetic plunger 216 is excited by the DC output of the rectifier circuit 226 . Relay switch 224 is conductive only when relay 222 is energized. The detection switch 128 has an actuator 220 that responds to the leading edge of the document being conveyed.
When the contact 20 is rotationally displaced by the document, the conductive state is switched from the contact 128a to the contact 128b. When contact 128a is cut off, relay 222 remains in the energized state momentarily for a short period of time corresponding to the amount of charge in capacitor 228, so that relay switch 224 remains in the energized state after contact 128a is cut off. Maintains conductivity for a short period of time. Therefore, the electromagnetic plunger 216 is only momentarily energized for the short period of time. Therefore, the ratchet wheel 192
After the pawl 210 is disengaged and the ratchet wheel 192 rotates once, the pawl 210 re-engages with the ratchet wheel 192. Therefore, when the document is conveyed, only a single rotation of the paper feed roller shaft 76 is achieved. By one rotation of the paper feed roller 74, the leading edge of the topmost sheet of photosensitive paper 6 is moved to the stop member 13.
The length of the photosensitive paper conveyance path 8 is set so that the photosensitive paper conveyance path 8 is conveyed by a distance sufficient to make contact with the photosensitive paper conveyance path 8 . The pressing member 132 that presses against the outer peripheral surface of the document feed roller 130 is made of, for example, a metallic spring steel material.

Guide plate springs 230 and 232 provided in the document transport path 12
As is clear from FIG. 12, which will be described later, this serves to ensure that the leading edge of the document is brought into contact with the stop member 138. The guide plate spring 234 provided on the photosensitive paper transport path 8 is... When the feed roller 136 is in the lowered position as shown in FIGS. 11 and 12, which will be described later, the leading edge of the photosensitive paper 6 touches the stop member
It works to ensure that it comes into contact with 38, and also
When the feed roller 136 rises from the first yielding state, the photosensitive paper 6 is pressed against the feed roller 136, thereby causing the photosensitive paper 6 to return to the upper side of the photosensitive paper transport path 8 (to the left in FIG. 7). The feed roller 13 prevents the document and the photosensitive paper from collapsing.
4,136 sandwiched between the two. To describe the operation, first, as shown in Figure 8, the electromagnetic plunger 21

Therefore, the switching mode of the detection switch 128 changes, and the electromagnetic plunger 21 is activated by the electric circuit shown in FIG.
6 is instantaneously excited. Therefore, the arm 214 is rotated clockwise around the pin 212, and the pawl 210 and the ratchet wheel 192 are disengaged. The rotational power from the sprocket wheel 160 is then transmitted to the feed roller shaft 76 via the spring clutch 194. 1st
Referring to FIG. 2, as the paper feed roller shaft 76 is rotationally driven, cams 172 and 190 integral therewith are rotated. The follower 170 responds to the cam 172, which causes the swinging arm 166 to pivot counterclockwise about the pin 168 under its own weight, thereby causing the rotation of the infeed roller 124 from one infeed roller 124 to the other infeed roller 126. Leave. At the same time, the follower 188 responds to the cam 190, which causes the swinging arm 184 to rotate clockwise around the pin 182 under the action of gravity, causing the lifting piece 176 to descend, thereby lowering one of the The other delivery roller 136 is separated from the delivery roller 134. The point at which the feed rollers 124 and 126 are separated is immediately after the leading edge of the document is sandwiched between the document feed roller 130 and the pressing member 1-32.

Therefore, even after the feed rollers 124 and 126 are separated, the document remains between the document feed roller 130 and the pressing member 13.
It is transported by the action of 2. Paper feed roller shaft 76
Therefore, by the rotation of the paper feed roller 74, only one sheet of the photosensitive paper 6 is conveyed to the photosensitive paper conveyance path 8. Photosensitive paper 6
The guide plate spring 234 prevents the photosensitive paper 6 from rising from the conveying path 8, and the leading edge of the photosensitive paper 6 is held at the stop member 138.
further conveyance is prevented. Therefore, if the paper feed roller 74 continues to rotate after the photosensitive paper 6 has stopped, the photosensitive paper 6 may become slack. Therefore, it is desirable that the length of the photosensitive paper transport path 8 be selected so that such slackness can be suppressed to an extent that does not adversely affect accurate alignment of the leading edges of the original and the photosensitive paper. The leading edge of the original being sandwiched between the original feeding roller 130 and the pressing member 132 is guided by the guide plate springs 230 and 232 and comes into contact with the stop member 138 .

At the same time, the cams 172 and 190 displace the followers 170 and 188 to rotate the swing arms 166 and 184, causing the feed roller 126 and the feed roller 136 to rise. Therefore, the feed rollers 124, 126 and the feed rollers 134, 136 are brought into close contact with each other. In response, the feed rollers 134 and 136 force the document and the photosensitive paper 6, whose edges have been aligned, to move in the conveying direction while keeping them stacked one on top of the other. Therefore, the leading edges of both papers are conveyed over the stop member 138. As described above, after the leading edge of the original comes into contact with the stop member 138 while the feed rollers 134 and 136 are separated, the feed roller 1

No matter what orientation the original is inserted from the original insertion table 18, in order to correct the orientation of the original as accurately as possible during this correction time, the position of the actuator 220 of the detection switch 128 along the original transport direction must be adjusted. Also, the outer diameter and rotation speed of the document feed roller 130 are appropriately selected. FIG. 14 shows the stopper claws 52, 54 and the paper feed roller 7.
4 is an enlarged view of the vicinity. In this embodiment, the restraining pawl 52
, 54 and the paper feed roller 74 are constant regardless of the amount of photosensitive paper 6 loaded. Therefore, photosensitive paper 6
When the loading amount of the photosensitive paper is relatively large, the uppermost surface 6a of the photosensitive paper
If the relative positions of the stopper claws 52 and 54 and the paper feed roller 74 are determined so that the tips of the stopper claws 52 and 54 do not come into substantial pressure contact with the tops 52a and 543a of the stopper claws 54, the loading amount of the photosensitive paper 6 can be determined. When the number of photosensitive paper mounting plates 44 is small, the angle of inclination of the photosensitive paper mounting plate 44 with respect to the horizontal becomes large, so that the tip of the uppermost surface 6b of the photosensitive paper comes into contact with the tops 52a and 54a with undesirably large pressure. In order to solve this problem, as shown in FIG. 15, a rubber piece 231 is pasted on the photosensitive paper mounting plate 44 in a position corresponding to the paper feed roller 74. The rubber piece 231 keeps the inclination angle of the photosensitive paper mounting plate 44 small even when the amount of photosensitive paper 6 loaded is small, so that the top end of the photosensitive paper 6 is substantially pressed against the tops 52a and 54a. prevent that. Referring again to FIG. 7, a five-cam 233 is fixed to the shaft end of the rotating shaft 72.

Linon link 2 having a long hole 239 into which a pin 238 is loosely inserted
40 is pivotally supported by the document insertion table 18. Therefore, when the document insertion table 18 is opened as shown by the imaginary line in FIG. is switched to contact 239. In response, electromagnetic clutch 246 is turned off; chain 162 and sprocket wheel 160 are stopped. This keeps you safe. As described above, according to the present invention, there is always a gap between the top end of the photosensitive paper and the stoppers 52 and 54, regardless of the amount of photosensitive paper stacked on the photosensitive paper loading plate. An appropriate gap is maintained or a light contact is made with very little pressure, and the stopper claw does not unnecessarily press the top edge of the photosensitive paper, preventing bending of the edge of the photosensitive paper and the resulting damage inside the copying machine. Paper jams can be effectively prevented, two-sheet feeding can be effectively prevented, and diagonal feeding can also be prevented.

Furthermore, since the position of the leading edge of the top surface of the photosensitive paper is not substantially displaced, the leading edge of the photosensitive paper and the leading edge of the document are reliably overlapped, and there is no noticeable misalignment of the leading edge. The effect is produced. Therefore, paper feeding is performed smoothly. Further, according to the present invention, the pressure contact force between the uppermost surface of the photosensitive paper and the paper feed roller is switched to an appropriate value according to the stacked amount of photosensitive paper on the photosensitive paper mounting plate, so that regardless of the size of the photosensitive paper, Paper jams of the photosensitive paper can be prevented, feeding of two sheets of photosensitive paper can be prevented, diagonal feeding of the photosensitive paper can be prevented, and the conveyance of the photosensitive paper can be carried out smoothly and reliably.
