A toy computer image processor assembly wherein a toy assembly in the form of a simulated computer is provided with hand manipulated actuating members in a keyboard section connected to image producing means in a screen section to selectively move such image producing means into and out of engagement with the screen and in selected directions along the screen.

A three-dimensional drawing device comprising a transparent hollow globe, a powder material disposed within the globe which adheres to the inner surface of the globe, a scribe disposed within the globe which can be used to draw upon the inner surface of the globe by scraping off the powder material, and controls for manipulating the scribe. The device can be used to form three-dimensional sketches and is primarily intended for use as a teaching aid and toy.

A drawing device adapted to produce line drawings or sketches on a transparent screen on top of a rectangular box-like case partly filled with a powder that adheres slightly to the undersurface of the screen to render it opaque. Disposed within the case is a stylus supported for sliding movement at the intersection of shiftable transverse and longitudinal rods. The extremities of the transverse rods are fastened to a set of parallel branches of a string loop operated by a control knob which when turned causes this rod and the stylus born thereby to move toward either end of the case, depending on the direction of knob rotation. The extremities of the longitudinal rod are fastened to a set of parallel branches of a second string loop operated by a second control knob when turned causes this rod and the stylus born thereby to move toward either side of the box, depending on the direction of knob rotation. The moving stylus normally engages the undersurface of the screen and acts to scrape powder therefrom to create a line whose contour depends on the path taken by the stylus under the control of one or both knobs. In order to produce sketches and drawings having discrete elements, a manually-operated interrupter mechanism is provided which when actuated depresses one of the rods to retract the stylus from the screen without, however, inhibiting shifting thereof, whereby it then becomes possible selectively to break the line drawn thereby.

A drawing template for facilitating the formation of images upon a spherical surface is disclosed. In a first embodiment the template comprises first and second transparent hollow hemispheres having indicia formed upon their surfaces such that the two hemispheres may be disposed about a spherical drawing surface and the indicia may then be used as a guide to form corresponding images upon the drawing surface. In a second embodiment, a planar sheet of flexible material is configured such that it will conform substantially to the shape of a sphere when placed in laminar juxtaposition therewith. Indicia formed upon the sheet of flexible material provide a guide by which images may be formed upon the drawing surface. Both embodiments of the drawing template of the present invention are particularly applicable for use with a three-dimensional drawing device which forms images upon the inner surface of a transparent sphere.
