Next, the configuration of the document transport assisting member 100 that can be used in the image processing device 1 will be described. FIG. 3 is a perspective view showing the configuration of the document transport assisting member 100, FIG. 4 is a plan view showing the configuration of the document transport assisting member 100, and FIG. 5 is a side surface showing the configuration of the document transport assisting member 100. It is a figure. Note that FIGS. 4 and 5 show a state in which the document M is housed in the document transport assisting member 100.

The document transport assisting member 100 is a carrier sheet for smoothly transporting the document M in the transport path R of the image processing device 1 when the image information of the document M is read by the reading unit 8 of the image processing device 1. is there. The size of the document M applicable to the document transport assisting member 100 is not particularly limited. The document transport assisting member 100 can be applied to, for example, a document M having a width of 36 inches.

As shown in FIGS. 3 to 5, the document transport assisting member 100 is opposite to the cover sheet 111 covering the first surface M1 read by the reading unit 8 of the document M and the first surface M1 of the document M. A support sheet 121 that covers the second surface M2 on the side is provided, and the cover sheet 111 and the support sheet 121 are adhered to each other.

The cover sheet 111 is a transparent PET sheet having a thickness of about 0.1 mm. The cover sheet 111 is a sheet having a size larger than the maximum size of the original M that can be used in the image processing device 1. That is, the cover sheet 111 is configured to be able to cover the entire surface of the document M. The surface of the cover sheet 111 in contact with the first nip roller 15a is subjected to fine uneven processing in order to reduce light reflection. As a result, even if the surface of the cover sheet 111 is scratched due to contact with the first nip roller 15a or the like, diffused reflection on the surface of the cover sheet 111 is reduced due to the scratches or the like, and the reading accuracy by the reading unit 8 is reduced. Can be secured.

The support sheet 121 is an opaque PET sheet having a thickness of about 0.1 mm. The surface of the support sheet 121 on which the document M is placed is, for example, white. The support sheet 121 has the same size as the cover sheet 111.

The document transport assisting member 100 has a first adhesive portion 131 to which the cover sheet 111 and the support sheet 121 are adhered. Specifically, as shown in FIG. 4, the first adhesive portion 131 is provided at the first end portion 128 on the first direction D1 side along the first axis. The first axis is a virtual axis along the transport path R when the document transport auxiliary member 100 is transported in the transport path R. The first direction D1 indicates the transport direction of the document transport assisting member 100 in the transport path R. The cover sheet 111 and the support sheet 121 are adhered to each other with their ends aligned on the D1 side in the first direction.

The first adhesive portion 131 is provided in a strip shape along the second axis intersecting the first axis. In the first adhesive portion 131, the cover sheet 111 and the support sheet 121 are adhered to each other by, for example, adhesive tape or ultrasonic welding.

Further, the document transport assisting member 100 is located at one end 129a of the second axis intersecting the first axis of the document transport assisting member 100, and is the first in the first axis than the first adhesive portion 131. It has a second adhesive portion 141 including a portion on the side of the second direction D2 which is opposite to the direction D1. The second adhesive portion 141 of the present embodiment is located at one end portion 129a of the document transport assisting member 100, which corresponds to the edge guide 19a side. Further, the second adhesive portion 141 is formed from the rear end Eb on the second direction D2 side of the first adhesive portion 131 toward the second direction D2. In the second adhesive portion 141, the cover sheet 111 and the support sheet 121 are adhered in the same manner as the first adhesive portion 131.

The cover sheet 111 and the support sheet 121 are not adhered to each other in the region of the second direction D2 from the second adhesive portion 141. That is, in the document transport assisting member 100, the second adhesive portion 141 is not formed in the entire region of the one side end portion 129a, and the second adhesive portion 141 is provided only in a part region of the one side end portion 129a. .. As a result, the openable area that separates the cover sheet 111 from the support sheet 121 becomes relatively wide, so that the document M can be smoothly inserted between the support sheet 121 and the cover sheet 111. Further, when the document M is accommodated in the document transport assisting member 100, the side end of the document M is regulated by the second adhesive portion 141, so that the document M does not protrude from the document transport assist member 100, and the document M is prevented from protruding. The edges can be protected.

In the document transport assisting member 100, the rear end 141e on the second direction D2 side of the second adhesive portion 141 is the rear end Eb on the second direction D2 side of the first adhesive portion 131 and the second direction D2 of the document transport assisting member 100. It is located on the D1 side in the first direction from the midpoint of the distance L1 from the rear end 100e on the side. As a result, more than half of the cover sheet 111 can be opened with respect to the support sheet 121, so that the document M can be smoothly inserted.

Further, the distance L2 between the rear end 141e of the second adhesive portion 141 and the rear end Eb of the first adhesive portion 131 on the first axis is shorter than 2 inches.

As a result, in particular, the distance L2 regulated by the second adhesive portion 141 becomes shorter than the short side of the minimum size document M, for example, the business card size document M, and even when the minimum size document M is accommodated. Since the corner ends of the original document M can be aligned with the first adhesive portion 131 and the second adhesive portion 141 with a part of the original document M exposed, the original document M can be easily accommodated in the original document transport auxiliary member 100. be able to.

Further, in the document transport assisting member 100, in addition to the first adhesive portion 131, a cover is provided in a region between the second adhesive portion 141 and the other side end portion 129b on the opposite side of the one side end portion 129a on the second axis. The sheet 111 and the support sheet 121 are not adhered to each other. That is, the document transporting auxiliary member 100 does not have an adhesive portion inside from the second adhesive portion 141 toward the other side end portion 129b. As a result, the size of the document M that can be accommodated in the document transport assisting member 100 is not fixed to one type, and various sizes of the document M can be applied. Specifically, the document transport assisting member 100 can accommodate documents M of various sizes ranging from business card size to 36 inch size.

The second adhesive portion 141 is separated from the first end Fa as one side end of the cover sheet 111 and the support sheet 121. Specifically, the length S2 of the first end Fa along the second axis of the document transport assisting member 100 and the second end Fb in the direction from the first end Fa of the second adhesive portion 141 to the other side end portion 129b. Is approximately 0.5 inches. The second end Fb of the second adhesive portion 141 forms a linear shape in the first direction D1. Further, the angle at which the rear end Eb of the first adhesive portion 131 and the second end Fb of the second adhesive portion 141 intersect is approximately 90 degrees. Therefore, the end portion of the document M can be reliably protected, and the document M is brought into contact with the rear end Eb of the first adhesive portion 131 and the second end Fb of the second adhesive portion 141 to bring the document M into contact with the original. The reading reference position of M is defined.

Further, in the present embodiment, the third adhesive portion 151 is formed along the first axis from the other end of the first adhesive portion 131 on the second axis opposite to the second adhesive portion 141. The dimensions of the third adhesive portion 151 arranged along the first axis are the same as the dimensions of the second adhesive portion 141. That is, the third adhesive portion 151 is not arranged in the entire region along the first axis of the document transport auxiliary member 100, but is arranged in a part of the region along the first axis of the document transport auxiliary member 100. Will be done.
A second adhesive portion 141 and a third adhesive portion 151 are provided at both ends of the document transport auxiliary member 100 on the second axis. That is, the dimension of the document transport assisting member 100 along the second axis is larger than the dimension of the document M that can be accommodated in the document transporting auxiliary member 100 along the second axis, and is second with respect to the accommodated document M. Margins are provided at both ends of the shaft. Further, no other adhesive portion for adhering the cover sheet 111 and the support sheet 121 is provided between the second adhesive portion 141 and the third adhesive portion 151. As a result, it is possible to accommodate a plurality of types of original documents M having different sizes.

Further, in the document transport assisting member 100 of the present embodiment, the side end Ea on the first direction D1 side of the document transport assisting member 100 and the second direction opposite to the first direction D1 of the first adhesive portion 131. The length S1 of the rear end Eb on the D2 side is the position of the first holding portion 50 in which the first transport roller 15 sandwiches the document transport assisting member 100 in the transport path R, and the reading unit 8 can read the document M. The length between the reading position Pt and the reading position Pt is larger than K1. The detailed position of the first holding portion 50 is the center position of the nip width when the document transport assisting member 100 is pressed by the first transport roller 15 and the first nip roller 15a in the transport direction. Further, the length K1 is the length from the position of the first sandwiching portion 50 to the reading position Pt in the transport path R, and is the length including a slightly bent portion of the transport path R. That is, the length K1 is not the shortest distance connecting the first holding portion 50 and the reading position Pt.
The reading unit 8 of the present embodiment is substantially equal to a line extending in the direction in which the reading region intersects the transport path R, but when the reading region has a certain length in the transport path R, it is upstream of the reading region. The end is considered the reading position Pt. In this case, the length K1 is the length from the position of the first sandwiching portion 50 in the transport path R to the upstream end of the reading region. Further, in the configuration in which a plurality of reading units 8 of the present embodiment are arranged in a direction along the transport path R, the length K1 is the first sandwiching portion 50 downstream of the most downstream reading unit 8 in the transport path R. It is the length from the position to the reading position Pt of the most upstream reading unit.
The length K1 between the position of the first holding portion 50 and the reading position Pt in the transport path R is, for example, 65 mm, and the length S1 between the side end Ea and the rear end Eb of the document transport auxiliary member 100 is about 70 mm. Is.

The side edge Ea of the document transport assisting member 100 is the edge of the cover sheet 111 and the support sheet 121 on the first direction D1 side. The rear end Eb of the first adhesive portion 131 forms a straight line along the second axis. The rear end Eb serves as a reference end in the first direction D1 of the document M. That is, the reading reference position of the document M is stabilized by bringing the end edge of the document M in the first direction D1 into contact with the rear end Eb. When the end side of the document M in the first direction D1 is brought into contact with the rear end Eb, the end side of the document M that is in contact with the rear end Eb becomes the reading start position Ps. That is, the scanning start position Ps corresponds to the most upstream end of the document M. Further, the region from the rear end Eb to the side end Ea is a margin region that does not contribute to the reading process by the reading unit 8. It should be noted that the entire region from the side end Ea to the rear end Eb does not have to be an adhesive region. That is, the rear end Eb of the first adhesive portion 131 may be formed, and the end side portions of the cover sheet 111 and the support sheet 121 on the first direction D1 side do not necessarily have to be adhered.

Next, the operation of the document transport assisting member 100 in the image processing device 1 will be described. 6 to 9 are schematic views showing the operation of the document transport assisting member 100.
First, the user accommodates the document M in the document transport assisting member 100. Specifically, as shown in FIG. 6, the cover sheet 111 is turned up with respect to the support sheet 121. At this time, the cover sheet 111 and the support sheet 121 are formed by the first adhesive portion 131 of the first end portion 128 and the second adhesive portion 141 and the second adhesive portion 141 provided in a part of the document transport auxiliary member 100 along the first direction D1. Since it is adhered to the third adhesive portion 151, for example, the second adhesive portion 141 covers the support sheet 121 as compared with the case where the second adhesive portion 141 is arranged on the entire end portion of the document transport auxiliary member 100 in the first direction. The sheet 111 can be turned up more greatly. This makes it easier to insert the document M between the cover sheet 111 and the support sheet 121. Of the original document M, the first surface M1 scanned by the scanning unit 8 is placed on the support sheet 121 with the first surface M1 facing upward. Then, the flipped-up cover sheet 111 is lowered toward the support sheet 121. As a result, the document M is housed in the document transport assisting member 100.

Further, the document M is housed in the document transport assisting member 100 so that each end side of the document M comes into contact with the rear end Eb of the first adhesive portion 131 and the second end Fb of the second adhesive portion 141. Since the distance L2 along the first axis of the second adhesive portion 141 is, for example, about 2 inches, which is relatively short, the cover sheet 111 can be turned up more than the support sheet 121, and the document M can be turned up more. With a part exposed, the corner ends of the document M can be aligned with the first adhesive portion 131 and the second adhesive portion 141. As a result, the document M can be easily accommodated in the document transport assisting member 100, and the reading reference position of the document M is defined. Then, the end edge of the document M that is in contact with the rear end Eb becomes the reading start position Ps.

Next, the document transport assisting member 100 in which the document M is housed is set at the transport start position of the scanner unit 5 of the image processing device 1. Specifically, the first end 128 is inserted from the supply port 6 along the transport path R with the cover sheet 111 facing upward so that the cover sheet 111 faces the reading unit 8. Once, the side end Ea of the document transport assisting member 100 is inserted until it comes into contact with the second transport roller 16. The position where the side end Ea of the document transport assisting member 100 comes into contact with the second transport roller 16 is the transport start position.

Here, the operation of the edge guides 19a and 19b when the document transport assisting member 100 is set at the transport start position of the scanner unit 5 will be described. FIG. 7 shows a state when the document M is guided for comparison, and FIG. 8 shows a state when the document transport assisting member 100 accommodating the document M is guided.

In the image processing apparatus 1 of the present embodiment, the edge guide 19a is a home-side guide, and the guide surface with which one end of the document M abuts serves as a set reference position that serves as a reading reference for the document M with respect to the scanner unit 5. It becomes 1 position HGa. Therefore, as shown in FIG. 7, when setting the document M, the edge guide 19b on the away side is moved according to the size of the document M with the edge guide 19a fixed. The position of the edge guide 19b is the position AGa.
On the other hand, as shown in FIG. 8, when the document transport assisting member 100 accommodating the document M is set, as shown in FIG. 7, when the document transport assisting member 100 is set with the edge guide 19a fixed, the document transport assisting member 100 is set. The reading reference of the document M shifts toward the + X direction with respect to the first position HGa as the reference position. That is, with respect to the first position HGa, the reading reference of the document M is such that the margin of the length S2 between the first end Fa and the second end Fb of the document transport assisting member 100 shifts toward the + X direction. Therefore, in the present embodiment, the edge guide 19a is moved from the first position HGa to the second position HGb in the −X direction. That is, the edge guide 19a is moved toward the −X direction by the margin of the length S2 of the document transport assisting member 100. That is, the length of the first position HGa and the second position HGb along the X-axis is the margin length S2 of the document transport auxiliary member 100. As a result, since the reading reference of the document M is located at the first position HGa, it is possible to prevent the reading position of the document M from being displaced.
The position of the edge guide 19b is moved to the position AGb corresponding to the document transport assisting member 100.

Next, the scanner unit 5 is driven. Specifically, the first transport roller 15, the second transport roller 16, and the reading unit 8 are driven. As a result, the document transfer auxiliary member 100 is conveyed toward the first transfer roller 15 along the transfer path R by the rotation of the second transfer roller 16.

When the document transfer auxiliary member 100 is conveyed along the transfer path R by the second transfer roller 16, the side end Ea of the document transfer auxiliary member 100 comes into contact with the first transfer roller 15, as shown in FIG. .. In FIG. 9, the second adhesive portion 141 is omitted. When the side end Ea comes into contact with the first transport roller 15, the transport speed of the document transport auxiliary member 100 slows down. On the other hand, since the document transport assisting member 100 is transported to the first transporting roller 15 side by the second transporting roller 16, a part of the document transporting auxiliary member 100 is distorted and the posture of the document transporting auxiliary member 100 changes in the transport path R. .. As the posture of the document transport assisting member 100 changes, the posture of the document M also changes. Here, if the reading unit 8 starts reading while the posture of the document transport assisting member 100 fluctuates, the separation distance between the reading unit 8 and the document M varies, and the reading accuracy deteriorates.
Therefore, in the present embodiment, the length S1 between the side end Ea of the document transport auxiliary member 100 and the rear end Eb of the first adhesive portion 131 is the first holding portion 50 of the first transport roller 15 in the transport path R. The length K1 between the scanning unit 8 and the scanning position Pt where the document M can be read is larger. That is, when the side end Ea of the document transport assisting member 100 comes into contact with the first transport roller 15, the reading start position Ps of the document M has not reached the reading position Pt of the reading unit 8, and the reading unit 8 reads. The margin portion of the first adhesive portion 131 of the document transport assisting member 100 faces the position Pt.

After that, when the document transfer auxiliary member 100 is conveyed to the downstream side of the transfer path R by the first transfer roller 15, the reading start position Ps of the document M reaches the reading position Pt, and the document M is started to be read. That is, when the document transport assisting member 100 is transported by the first transport roller 15, the document transport assisting member 100 becomes substantially linear and the reading of the document M is started in a stable posture. Therefore, the separation distance between the reading unit 8 of the image processing device 1 and the document M is constant and stable, so that the reading accuracy can be improved.

2. Embodiment 2
Next, the second embodiment will be described. FIG. 10 is a plan view showing the configuration of the document transport assisting member 100A according to the present embodiment. Hereinafter, a configuration different from the configuration of the first embodiment, that is, a configuration of the second adhesive portion 141A of the document transport assisting member 100A will be mainly described. Since the configurations other than the second adhesive portion 141A are the same as those in the first embodiment, the description thereof will be omitted.

As shown in FIG. 10, the document transport assisting member 100A includes a cover sheet 111 that covers the first surface M1 of the document M, and a support sheet 121 that covers the second surface M2 of the document M.
