Abstract
A housing structure includes a first structure, which has body frames and a first shaft supported by the body frames, a second structure to be movably supported between an opened position and a closed position by the first shaft, and a positioning device to position the second structure in relation to the first structure in the closed position. The positioning device includes a first engagement portion provided on the first structure, a second engagement portion provided on the second structure and engaged with the first engagement portion in the closed position, a first biasing device to bias the second engagement portion toward the second structure, and a second biasing device to bias the second engagement portion toward the first structure. The positioning device positions the second structure in relation to the first structure by biasing forces of the first biasing device and the second biasing device.
