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.

The rotary shaft member is therefore unable to rotate with respect to the connection member and the connection member is rotatable with respect to the body unit.
