Patent ID: 8401434

Claim:
A powder storage device that stores powder to be supplied or recovered powder, the powder storage device comprising: a container that is extractably mounted on a container receiver, and in which powder to be supplied or recovered powder is stored; a cover that is movable between an open state and a closed state, the cover uncovers the container receiver in the open state and covers the container receiver in the closed state; and a restricting mechanism that restricts the cover to the closed state, and the restricting mechanism comprising: a restricting member that is disposed on a side of the container receiver, the restricting member is located at a first position when the container is not mounted on the container receiver, and the restricting member is located at a second position when the container is mounted on the container receiver; and a restricted member that is disposed on a side of the cover, the restricted member interferes with the restricting member so as to restrict the cover to move to the closed state when the restricting member is located in the first position, and the restricted member does not interfere with the restricting member so as to allow the cover to move to the closed state when the restricting member is located in the second position, wherein the restricting member obstructs the container, which is mounted in the container receiver, to be carried out from the container receiver when the restricting member is in the second position, wherein the restricting member is movable along a direction intersecting with an inserting/extracting direction of the container, and the restricting member moves linearly.
