ABSTRACT:
A writing guide for writing letters and words in a transverse line on a sheet mounted on the flat surface of a baseboard, includes a rectangular frame movable along a detent rod carried by the baseboard. The frame is rotatable around the rod to enable the sheet to be placed on and removed from the baseboard. The frame has two rigid spaced rails joined by rigid end plates. A flexible string has two laterally movable sections disposed between and parallel to the rails to define a space for writing transversely along the sheet. The string may be connected in electric circuit with an electrically operable sounding device, power supply, and metal tip of a writing implement, to sound an alarm when the tip of the writing implement contacts one of the string sections.
