Abstract: The invention relates to a portable device for marking a surface, including a casing (2) having a front face (6) having a rectangular opening (6A) for the passage of a marking member, the front face (6) of the casing being provided with a stiffening frame (15) surrounding the passage opening (6A), this stiffening frame (15) being provided with an indexing system (18) adapted to cooperate with a complementary indexing system (19) equipping each of the tooling of a series of removable tooling (20A, 20B, . . . ) for positioning the device on the surface to be marked, each removable tooling (20A, 20B, . . . ) of the series and the stiffening frame (15) including at least one of the elements of a magnetic fastening system with two elements, namely a magnet (21A) and a ferromagnetic material (21B).

Abstract: The invention relates to a portable appliance for marking a surface, the appliance comprising a housing (2) presenting a front face that is open for passing a marker member that is moved by a device for moving the marker member in a two-dimensional marking zone (Z). The housing is provided with a positioning nose (30) for positioning the appliance over the surface for marking, the positioning nose defining firstly the two-dimensional marking zone (Z) facing the front face of the housing and at a distance from the front face, and secondly an opening (35) extending the top wall for enabling the two-dimensional marking zone to be viewed, the top wall of the housing being fitted with a display screen in such a manner that the screen and the two-dimensional marking zone as seen through the opening of the positioning nose appear simultaneously in the field of view of an operator.
