２の表面とに摩擦を増すことができる。The engaging portion 322 is used to move the free end of the main body 200 in the moving direction (in this embodiment, the main body 20 is moved).
This mechanism is a one-way clutch that operates in the direction of opening 0, and has a second friction portion 323 on its surface. In this embodiment, a roller supported by a shaft is described, but an arc-shaped member, a roller, or the like may be used. The second friction portion 323 is the first friction portion 3 described above.
13, the surface of the engaging portion 322 may be directly formed with one or more irregularities, or may be directly meshed, and may be formed with one or more irregularities. A cover, a film, rubber, or the like having the following may be attached or adhered to the surface of the engagement portion 322.

明らかである。In this embodiment, the surface of the first friction portion 313 is described as having a uniform roughness of the mesh. However, as the surface of the sliding contact surface 321 moves from the base end to the end, the mesh of the mesh increases. The roughness may be changed gradually. With this configuration, when the free end of the main body 200 is opened, the friction generated between the first frictional part 313 and the second frictional part 323 increases or gradually increases in the direction in which the main body 200 closes by its own weight. The unit 200 slowly closes. It is also clear that the second friction portion 323 may be configured in the same manner as the first friction portion 313 described above.

を防止することができる。With the above configuration, when a sheet is jammed in the upper stage of the sheet conveying device, the sheet conveying device is pulled out of the device, the main body 200 is opened, and the sheet is removed. At this time, when the main body 200 moves in the closing direction by its own weight, the surface of the second friction portion 323 is moved to the first friction portion 313.
Is moved, and the friction generated between the first friction portion 313 and the second friction portion 323 is fixed or gradually increased, and the main body 200 is slowly closed so as to approach a stationary state. Thereby, it is possible to prevent the main body 200 from closing suddenly.
