Abstract
In a clamshell-type image forming apparatus in which the upper unit is rotatably openably connected to the lower unit and in which the upper unit is biased in the opening direction by a biasing member, a hook is disposed at the upper unit and an engagement member is disposed at the lower unit for preventing the upper unit from being opened when the engagement member is engaged with the hook. The engagement of a lock member with the hook in association with the closing operation of a front cover, prevents the hook from being rotated. The disengagement of the lock member from the hook in association with the opening operation of the front cover, allows the hook to be rotated.
