Abstract

An apparatus for making drawings including a platen, an X-Y forcer slidably connected to the platen and a high speed holder adjustably connected to the forcer. The holder includes a plurality of separately actuatable mechanisms with each mechanism being connected to a tool for movement of the tool into or out of contact with a working surface. Means are included to precisely control each of the mechanisms in controlling the degree of contact which the tools make with the working surface. Also, means are included to precisely position each tool with respect to the mechanism which moves the tool into contact with the working surface. An apparatus for performing a working operation on a surface which apparatus includes a platen, an X-Y forcer slidably mounted thereon and a tool carried by the forcer for contact with the surface. Additionally, the apparatus includes means to vary the force applied by the tool against the working surface in response to the speed of movement of the tool with respect to the surface.
