Abstract
An electromechanical writing device comprising a writing head, a writing head carrier for carrying the writing head, a guide along which the writing head carrier is movable during a writing operation, a writing platen over which, in operation, a recording medium, e.g. paper, is moved during the writing operation, a shearing edge forming part of the writing platen and extending in a direction parallel to the direction of movement of the writing head, and a roller knife mounted for movement along the guide and cooperating with the shearing edge to permit the recording medium to be cut.
Claims7
An electromechanical writing device comprising:
- a writing head;
- carrier means for carrying the writing head;
- guide means along which the carrier means is movable during a writing operation;
- a writing platen over which during a writing operation a recording medium is moved;
- a shearing edge forming part of the platen and extending in a direction parallel to the direction of movement of the writing head, said shearing edge being disposed beneath the writing area of said writing head;
- a knife carrier slidably mounted on said guide means and having generally cylindrical roller knife rotatably mounted on said knife carrier and adapted to cooperate with said shearing edge to cut the recording medium;
- and
- coupling means to selectively lock said knife carrier to said carrier means so that upon actuation said knife carrier slides along said guide means in unison with said carrier means to cut the recording medium.
