A sheet processing apparatus has a main body with an insertion slot for a sheet cassette. The sheet cassette has a moveable pin member. A housing in the main body includes a lever partially rotatable about a first axis. The lever has a pin engagement portion at an end of the lever that rotates about a second axis and has an engagement groove into which the pin member can be inserted from a first pin engagement position and a second pin engagement position when the lever has rotated about the first axis. An elastic member applies a force to the lever to rotate the lever toward the insertion direction of the cassette. The housing includes a chassis having a guide groove extending along the insertion direction. The guide groove includes an inclining portion that is inclined with respect to the insertion direction.

An image forming apparatus includes an operating section. The operating section projects forward from an upper housing of the image forming apparatus. The operating section includes an input section and a display section. The input section is for receiving input of image forming information. The display section is disposed adjacent to the input section and displays the image forming information thereon. A position of the display section is switchable between a first position and a second position. The first position is where the display section is flush with the input section. The second position is where the display section is tilted forward more than the input section, by turning the display section on a front edge side of the display section as a pivot to raise a rear edge side of the display section upward from the first position.
