[0050] First, according to figure 2 Next, the sheet conveyance device X1-1 will be described. figure 2 (a) is a schematic plan view omitting the driven rollers 18b and 19b of the sheet conveyance device X, figure 2 (b) is omitted figure 2 (a) is a schematic side view of the sheet transport device X1 - 1 operating the knob 28 (an example of a manual operation unit). In this sheet conveying device X1-1, a shaft (an example of an upstream conveying roller shaft) 18a1 of the driving roller 18a is rotatably attached to a shaft supporting portion 27a1 via a bearing not shown in the figure. 27a1 is provided on the side plate 27 integrally formed with the not-shown base. In addition, an operation knob 28 integrally formed with the pulley 24 is attached to the same shaft as the upstream drive roller shaft 18 a 1 via the one-way clutch 22 . The operation knob 28 may be attached to the same shaft as the downstream driving roller shaft 19a1 (an example of the downstream conveying ...

[0057] Next, according to image 3 The sheet conveying device X1-2 will now be described. here, image 3 (a) is a schematic plan view omitting the driven rollers 18b and 19b of the sheet conveyance device X1-2, image 3 (b) is omitted image 3 (a) is a schematic side view of the operation knob 28 (an example of a manual operation unit). for with figure 2 The same components of the illustrated sheet conveyance device X1 - 1 are given the same reference numerals and their descriptions are omitted.
[0058] In this sheet conveyance device X1-2, during normal sheet conveyance (during non-jamming processing), the operation knob 28 slidably attached to the upstream drive roller shaft 18a1 of the drive roller 18a is always held by the spring 33 An elastic body such as (an example of a sliding mechanism) biases in a direction perpendicular to the side plate 27 and away from the side plate 27 . Therefore, during normal sheet conveyance, the gear 29 integrally formed with the ope...

[0064] Next, according to Figure 4 Next, the sheet conveying device X1-3 will be described. here, Figure 4 (a) is a schematic plan view of the sheet conveying device X1-3 omitting the driven rollers 18b and 19b and including peripheral parts of the transfer belt rotating roller 17, Figure 4 (b) is Figure 4 (a) is a schematic side view of the sheet conveying device X1-3. The same reference numerals are assigned to the same components as those of the sheet conveying device X1 - 1 and the sheet conveying device X1 - 2 , and description thereof will be omitted.
[0065] In the sheet conveyance device X1-3, an operation knob 28 (an example of a manual operation unit) is slidably mounted on the same shaft as the downstream side drive roller shaft 19a1. When the photosensitive drum 10 abuts against the transfer belt rotating roller 17 on the downstream side of the driving roller shaft 19a1 on the downstream side, the operating knob 28 is always biased toward the side plate 27...
