Claims

[Claims for Utility Model Registration] A lower main body including a paper transport section, a first upper support frame that supports an optical system unit and is rotatably attached to the lower main body, and supports an electrophotographic unit. In a shell-type electrophotographic apparatus such as a laser printer or an electrophotographic copying machine, the shell-type electrophotographic apparatus includes a second upper support frame rotatably attached to the lower main body, and the first upper support frame is opened. an opening means for opening the second upper support frame at the same time; and closing only the second upper support frame from the open state of the first upper support frame and the second upper support frame. a safety lock mechanism that double-locks the second upper support frame with respect to the lower body when the second upper support frame is closed; and A shell-type electrophotographic apparatus, comprising: a release means for releasing the lock by the safety lock mechanism when the body is closed.
