Abstract: An information processor which is capable of preventing damages caused by rotation of a display panel holding unit to a display and a body of the information processor. A rotary shaft member is connected to a display panel holding unit and directed perpendicularly, an outer end of a lock bar is inserted into a lock hole of the body unit and an inner end thereof is removed from a lock hole of the rotary shaft member.
