In an interlock device for turning a switch on and off in accordance with closing and opening of a plurality of covers covering a body of an electronic apparatus, one striker protrudes from each of the covers. An engagement member is provided inside the body of the electronic apparatus to move in a predetermined direction to contact and separate from the switch to turn the switch on and off. All the strikers contact the engagement member to turn on the switch when all the covers are closed. At least one of the strikers separates from the engagement member to turn off the switch when the corresponding cover is opened.

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.

An interlock system includes first and second racks movable in parallel to each other in a longitudinal direction between opening and closing positions in conjunction with opening and closing of the first cover, respectively. A housing is provided to slidably accommodate the first and second racks in the longitudinal direction. A pinion unit is provided and is sandwiched by the first and second racks. The first and second racks have meshing sections respectively meshing with the pinion unit at one side surfaces extending in the longitudinal direction facing each other. The pinion unit slides in the longitudinal direction by a prescribed length in conjunction with movement of at least one of the first and second racks. The interlock switch is turned on and off in accordance with a sliding length of the pinion unit in the longitudinal direction.

An image forming apparatus includes an outer cover in which an air intake and an exhaust outlet are formed, an image forming unit, a fixing device to fix an image on a recording medium and including a fixing casing in which a sheet inlet and a first exhaust opening are formed, and a thermal shield disposed above the sheet inlet of the fixing device and between the fixing device and a component adjacent to the fixing device, an air channel to guide air sucked in through the air intake to the exhaust outlet, defined by the thermal shield as well as the fixing casing. The first exhaust opening formed in the fixing casing communicates with the air channel formed by the thermal shield and the fixing casing to merge the hot air discharged from the fixing device into the air flowing in the air channel.
