The present invention relates to a metal-sheet board or blackboard with magnetic features having two or three movements, which plots and represents reality in four dimensions (horizontal, vertical, depth and time) and which describes reality objectively, in which a T-shaped ruler is moved on a rail along the horizontal or X axis by a digital stepper motor controlled by a driver and software on the computer (horizontal movement). Furthermore, a tool truck surrounding the T-shaped ruler moves along the entire length (vertical movement) or Y axis thereof, actuated by a digital stepper motor controlled by a driver, which is in turn controlled by software on the computer, with these two movements controlled by mathematical speed and acceleration functions.

A display apparatus includes circuitry to receive an input of a plurality of strokes representing a drawing that includes one or more drawing components including a first drawing component. The plurality of strokes is divided under a predetermined condition to obtain the one or more drawing components. The circuitry stores, in a memory, each of the one or more drawing components and drawing data representing the drawing. The circuitry displays, on a display screen, in response to receiving an input of a second drawing component, the drawing represented by the drawing data based on the first drawing component and the second drawing component.

The present invention provides for a wall mountable system for automated drawing of an image upon a wall which includes a horizontal mounting track for mounting on a wall, a robot having a y-track rigidly mounted it where the robot and the mounted y-track travel along the horizontal track. An end effector, which includes a pen holding mechanism holding a pen, is in electrical communication with the robot and travels along the y-track of the robot. The present invention provides a system and device that can attach to a wall or vertical surface in a damage-free manner and draw fast any complexity or style image of custom size in both the horizontal (X) and vertical (Y) directions, that is easy to remove and transport and require small floor space to operate.

Certain embodiments of the invention include an apparatus for creating a line. Certain embodiments of an apparatus include two or more reels having an extendable and retractable cord. Pulling the two or more reels apart allows for the creation of a line of various sizes. In certain embodiments, the two reels share a single cord. In certain embodiments, a first reel has a first cord with a first attachment end that joins with another attachment end. Certain embodiments include a reel with a magnet, allowing attachment to a magnetic surface. Certain embodiments of the invention include a system for creating a line. In certain embodiments, the system includes an apparatus, and a pin having a magnet. Certain embodiments of the pin help to change the direction of the cord.

A cutting machine head and a cutting machine are provided in the present invention. The cutting machine head includes a fixing plate, a cutter holder, a cutting component, a machine head lifting mechanism and a machine head rotating mechanism. The cutter holder is mounted on the fixing plate. The machine head lifting mechanism is connected to the cutter holder, and is used to drive the cutter holder to move up and down on the fixing plate. The cutting component includes at least two cutter head assemblies mounted on the cutter holder. The machine head rotating mechanism is connected to the cutter head assemblies for driving the cutter head assemblies to rotate. The rotating angle of each cutter head assembly of the cutting machine head can be controlled. The machine head rotating mechanism controls the cutter head assembly to rotate when the machine head is cutting, and the resulting cutting line has no flaws, which can ensure the integrity of the cutting pattern.

A drawing device includes a pen fixed to a cartridge, a mover, a conveyer, a processor, and a memory. The memory stores for each classification of each of a plurality of objects, drawing data representing control conditions of the mover and the conveyer for drawing the object, and angle data representing a fixed angle of the pen with respect to the cartridge when drawing the object. The processor receives at least one of the classifications of the plurality of objects, reads out and acquires, from the memory, the drawing data and the angle data corresponding to the received at least one classification. The processor also displays, on a display, fixed angle information corresponding to the fixed angle represented by the acquired angle data, controls the mover and the conveyer on the basis of the acquired drawing data, and draws the object of the received classification on a target object.
