Abstract

PURPOSE:To transfer an envelope without rolling a corner of the envelope and prevent occurrence of jam, etc., before resist securely by providing a means to release pressure contact in a zone where corners of sheet materials such as envelopes in at least one of a pair of rotary bodies. CONSTITUTION:When an envelope 4 is supplied to a metal roller 1 and a rubber roller 6 which are stopped with its right front part corner 41 in the advancing direction at the forward end inclined diagonally, if a fold of the corner 41 is outside, with curling produced down, the corner 41 of the envelope 4 gets into a cut part 61 or 62 of the rubber roller 6 to be free from getting in contact with the rubber roller 6. The corner 41 therefore continues to advance. Curling at the corner 41 is not increased, and an edge part 42 of the envelope 4 gets in contact with an intersection 51 at a nip part 5 of the metal roller 1 with the rubber roller 6. Diagonal advance of the envelope 4 is then corrected gradually about the intersection 51 for a center.

[Conventional example] Conventionally, a resist conveying section in a sheet material conveying device that conveys sheet materials including envelopes, etc., has the following structure, as shown in FIG.
It consists of a metal roller 1 and a rubber roller 2, which are in pressure contact with each other so as to rotate or stand still. To explain its operation, first, when the metal roller 1 and the rubber roller 2 are stationary, the envelope 3 is guided by a guide member (not shown) such as a guide plate.
The edge 31 comes into contact with the outer peripheral surface of the metal roller 1, and then the edge 31 gradually comes into contact with the nip portion 5 between the metal roller 1 and the rubber roller 2 along the outer peripheral surface. Further, since the envelope 3 is conveyed a certain distance by a conveying means (not shown) from the direction of the rear edge 32, a certain amount of loop is generated in the envelope 3, and if the front edge 31 of the envelope Even if either the left or right side advances and the envelope is sent diagonally, during this loop formation period, the amount of diagonally advanced is absorbed,
As a result, both the left and right ends of the leading edge 31 abut against the nip 5, the skewed feeding of the envelope is corrected, and then the metal roller 1 and the rubber roller 2 begin to rotate, and the envelope 3 is conveyed downstream.

[Problems to be Solved by the Invention] Incidentally, as shown in FIG. 12, there are many envelopes in which the fold line at the corner 41 of the envelope 4 protrudes outward. If such an envelope is fed diagonally, as shown in FIG.
It will come into contact with. However, if the curl 42 exists in the protruding part of the corner 41, the corner 41
The curl direction (arrow A) is further increased by contacting only the sides. As a result, it does not reach the nip 5 between the metal roller 1 and the rubber roller 2, and is not conveyed even when both rollers 1.2 rotate, resulting in a so-called "pre-registration jam".

The sheet material conveying device is shown in Fig. 2. Figure 1. As shown in FIG. 4, it consists of a metal roller 1 and a rubber roller 6 that is in pressure contact with the metal roller 1. This rubber roller 6 has a portion where the envelope 4 is guided from a guide member 20.21 such as a guide plate, through which the corner portions 41 at both ends of the envelope 4 pass, and a portion adjacent thereto have been removed, and cutout portions '61.62 is provided.

The guides 20 and 21 can be slid by the operator according to the size of the sheet material, and are adjusted to the position shown in FIG. 1 (size L) when sending an envelope. Therefore, the notches 61 and 62 of the rubber roller 6 and the space between them (at the center of the notch) are also configured to have the same size. As a result, the envelope is conveyed so that the corner of the envelope corresponds to the notch.

Therefore, the sheet material (including envelopes) aligned on the manual feed tray 26 is placed on the upper and lower guide plates 29.30J1.
: Since it is not guided, it is sent toward roller 1.6 by roller 25e. Here, since the rollers 1 and 6 are stopped, a loop is formed in the sheet material. Next, the operation of this embodiment is illustrated in FIG. The explanation will be given with reference to FIG.

If the envelope 4 is fed to the stopped metal roller 1 and the rubber roller 6 with the right front corner 41 in advance and inclined obliquely, the fold of the corner 41 will protrude outward. Even if the envelope 4 curls downward, the corner 41 of the envelope 4 does not come into contact with the rubber roller 6 because it enters the notch 61 or 62 of the rubber roller 6, as shown in FIG. Section 41 continues as it is.

does not increase, and the edge 43 of the envelope 4 abuts the intersection 51 of the nip 5 between the metal roller 1 and the rubber roller 6. Then, the skew of the envelope 4 is gradually corrected around this intersection 51, and eventually the entire edge 43 comes into contact with the nip 5. Then, the envelope 4 whose skew has been corrected is
Thereafter, the metal roller 1 and rubber roller 6, which start rotating, smoothly transport the paper to the downstream side. On the downstream side,
It is printed by a printer, or read by a reader if the envelope is a document. That is, the present invention is applicable to printing devices, reading devices, and the like.

Although the sheet material conveying device having a pair of roller rotating bodies has been described above, the present invention is not limited to the above embodiments, and may also be a rotating moving body such as a pair of upper and lower belts. A notch may be provided in the area of the belt through which the corner of the envelope passes, and the belts may be released from pressure contact with each other. Further, as shown in FIG. 6, it is of course possible to use a transfer belt 7 instead of the rubber roller 6 on only one of the upper and lower sides, and to provide cutouts 71 and 72 in the transfer belt 7.

Furthermore, in the above-described embodiments, the notch portion of the roller is shown as a means for releasing the pressure contact, but the present invention is not limited to this. For example, a roller may also be placed at the notch to reduce its diameter (FIG. 7). Alternatively, only that part may be missed when sending the envelope (Figure 8).

Further, the means for releasing the pressure contact may be moved in the thrust direction of the roller depending on the size of the envelope (
Figure 9). Alternatively, the side guides may be shifted so that the corners of the envelope face the release means (10th
figure). At this time, the printing start position in the printing section is also shifted at the same time.
