Spacing device and image forming apparatus

摘要

A spacing device includes a spacing member that spaces first and second rotating bodies having first and second shaft portions, respectively, apart from each other. The spacing member is provided on the second shaft portion and includes a supporting portion that supports the first rotating body; and an opening through which the second shaft portion extends and including an idling portion that allows a hook part of the second shaft portion to rotate idle, and a catching portion that catches the hook part. The first and second rotating bodies are spaced apart when the hook part is in the catching portion and the first rotating body is supported by the supporting portion. The first and second rotating bodies are allowed to rotate when the spacing member rotates until the supporting portion is oriented downward in a direction of gravitational force and the hook part moves to the idling portion.

主权项

1. A spacing device comprising:
at least one spacing member that spaces a first rotating body and a second rotating body apart from each other, the first rotating body having a first shaft portion, the second rotating body having a second shaft portion, one of the first rotating body and the second rotating body being movable toward and coming into contact with another, wherein the spacing member is provided on one of the first shaft portion and the second shaft portion and includes
a supporting portion that supports one of the first rotating body and the second rotating body that is free of the spacing member; anda portion having an opening through which the one of the first shaft portion and the second shaft portion extends, the opening including an idling portion and a catching portion, the idling portion allowing a hook part included in the one of the first shaft portion and the second shaft portion to rotate idle, the catching portion being provided between the supporting portion and the idling portion and catching the hook part, wherein the first rotating body and the second rotating body are spaced apart from each other when the hook part is in the catching portion of the spacing member and the one of the first rotating body and the second rotating body is supported by the supporting portion of the spacing member, and wherein the first rotating body and the second rotating body are allowed to rotate when the one of the first rotating body and the second rotating body is rotated and causes the spacing member to rotate until the supporting portion of the spacing member is oriented downward in a direction of gravitational force and the hook part that has been in the catching portion of the spacing member moves to the idling portion.
