An inkribbon cartridge for a printer is disclosed which compulsorily keeps a definite form by a cooperation with its box member and a lid member.
The box member which comprises a plurality of concavities on the outside of a wall and a plurality of projections on the upper end of the wall near the concavities is engaged with the lid member which comprises a plurality of hooks which is inserted in the concavities to prevent outward deformation of the wall and a plurality of cuts which associate with the projections to prevent inward deformation of the wall.
By these provisions, in- and outward deformations of the wall of the box member can be undertaken by the lid member and the inkribbon cartridge compulsorily keeps its definite form.
