摘要： The present disclosure relates to a drawing device for creating a pattern, wherein the drawing device comprises a gear assembly that rotates upon movement of the device, the gear assembly being operatively coupled to a cam and a cam follower, such that rotation of the gear assembly rotates the cam and causes the cam to bear against the cam follower. Movement of the cam follower thereby causes lateral movement of a marker carriage housing at least one writing instrument.

摘要： A positioning jig includes a holding portion, a contact portion, and an operating portion. The holding portion holds the cartridge. A portion of the contact portion contacts a writing portion of the pen when the cartridge is held in the holding portion and the pen is held in the accommodating portion. The contact portion is able to rotate with a direction in which an axis of the pen extends as a first rotational axis. The operating portion performs an operation to rotate the contact portion. The contact portion restricts rotation of the pen about the first rotational axis with respect to the contact portion by contacting the writing portion of the pen and positions the pen in a rotational direction about the first rotational axis with respect to the cartridge.

摘要： A framing square including an integrated protractor feature is provided. The framing square includes a blade section, and a tongue section joined at a corner section. The corner section further includes a pivot opening, to rotatably couple the framing square to a workpiece. The blade section includes an array of marking openings. The marking openings are spaced from each other in the array, and the array is positioned a first distance from the pivot opening along a longitudinal axis of the blade. The marking openings can be sized to receive a particular marking instrument (e.g., a pencil or knife) for use with a particular framing square.

摘要： A newly proposed articulating invention, each of whose four constituent embodiments is designed to trisect any of a multitude of suitably described angles by means of becoming properly set to its designated magnitude; thus automatically portraying a motion related solution for the trisection of an angle that discloses complete routing details of a pathway that leads from such designated magnitude all the way back to its trisector; thereby discerning the whereabouts of certain intersection points which evade detection when attempting to otherwise locate them by means of applying only a straightedge and compass to an angle of such designated magnitude; furthermore projecting finite lengths of any trisector that bears cubic irrational trigonometric properties, being those that cannot be duplicated, but only approximated, when applying a straightedge and compass to a given length of unity; and being of a unique design that could be adapted to function as a level.

摘要： A plotter includes a mounting portion, a first movement mechanism, a second movement mechanism, a processor, and a memory. The mounting portion is configured to mount with a pen containing a liquid. The first movement mechanism is configured to relatively move the mounting portion and a workpiece in a movement direction. The second movement mechanism configured to relatively move the mounting portion and the workpiece in a direction intersecting the movement direction. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring plot data, acquiring information relating to a remaining amount of the liquid of the pen, setting a relative movement speed of the mounting portion and the workpiece, and controlling the first movement mechanism and the second movement mechanism at the set movement speed, and performing drawing on the workpiece.

摘要： A plotter apparatus inscribes a polygon in a circle, and includes a ruler body, a first slider, a second slider, multiple brachiums, and a nib member. The ruler body comprises a knap, and a first ruler groove and a second ruler groove to allow movement of the first slider and the second slider. The brachiums are connected across the ruler body via pivots. The nib member allows the drawing of the circle. A fourth brachium is attached to a predetermined numbered hole on a second and a third brachium as per the number of sides required on the polygon. The length of each side of the polygon is retrieved between the knap and a slider. Cyclic arcs, with the determined length as a length of one side of the polygon, are drawn along the circumference of the circle. The arc intersections on the circle are joined together to define the polygon.

摘要： 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.

摘要： 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.

摘要： A drawing apparatus includes a drawing unit, a test-writing portion, and a control unit including a drawing tool identification unit.At least one drawing tool is loaded in the drawing unit and the drawing tool draws on a drawing target and a drawing medium different from the drawing target. A drawing medium is placed on the test-writing portion. The drawing tool identification unit acquires a test target image from an area on the drawing medium drawn with the drawing tool in the test-writing portion, and identifies a type of the drawing tool loaded in the drawing unit on the basis of the test target image.
