A drafting machine comprising:
- a drawing board for mounting a drawing thereon;
- first guide path means for a first traveling carriage extending in the horizontal direction attached to said drawing board defining an X-axis;
- second guide path means for a second traveling carraige extending in a vertical direction attached at said first traveling carriage defining a Y-axis;
- a drafting head located at said second traveling carriage containing a straight edge receiving installation for attachment of straight edges to be rotatable and displaceable in any desired position on said drawing board by means of X-Y drives located in said first and second traveling carriages so that said drafting straight edges may be adjustable to any random angle with respect to said X- and Y- axes;
- distance and angular measuring devices in said traveling carriage and at said drafting head;
- computer means connected with said distance and angular measuring devices for determination of digital X-Y coordinates and of angles with respect to said X- and Y- axes of the position of said drafting head upon said drawing board;
- display means at said drafting head for providing a display output of said X-Y coordinates and said angles determined by said computer means;
- input keyboard means at said drafting head for enabling manual input of data into said computer;
- X-Y drives for displacement of said drafting head upon said drawing board and for enabling rotational drive of said drafting head for rotating said drafting head on said drawing board;
- a displacement sensor and a rotational sensor connected with said computer means attached at said drafting head capable of being actuated by manual operation to actuate said computer means to issue appropriate control signals to said X-Y drives for displacement and rotation of said drafting head;
- operational and travelling path programs for enabling selective control of all movements and rotation of said drafting head by manual operation instead of by said computer means;
- an X.sub.1 and Y.sub.1 scriber on said drafting head having high dynamics and a small working range for lettering and small size symbols equipped with a receptacle for stencil pens or similar writing implements which are located in receptacles at said drafting head, said receptacle for said stencil pens being capable of executing any desired travel curve within the working range by means of said X-Y drives;
- and
- a lowering mechanism upon said drawing board whereby a writing implement contained in said receptacle can be lowered or lifted onto or off said drawing board in order to thus enable drawing of desired symbols by actuation of said X-Y drives and of said lowering mechanism with appropriate travel path information by said computer means with all operational and travel path programs for said drafting head as well as for said X.sub.1 -Y.sub.1 scriber being called up at least by said input keyboard at said drafting head.
