摘要

An educational appliance is disclosed for teaching children handwriting skills. The appliance includes a tablet which supports a sheet-like member having an inscribable surface. A clutch having an upright spindle is mounted to the tablet. The clutch includes a ratchet mechanism which is oriented to permit rotation of the spindle only in a counterclockwise direction. A transparent disc is removably mounted to the spindle for rotation therewith. The disc includes at least one aperture adapted to receive the pointed end of a writing implement. The operation is such that the writing implement inscribes a circle on the sheet that is sandwiched between the support surface of the tablet and the disc, during rotation of the disc about its axis of rotation, thereby instilling a habit in the child of drawing circles in a counterclockwise direction.
