Abstract

An information recording device containing a body in the form of a thin plate having at least one and preferably three wheel wells rotatably receiving an alpha wheel, numeric wheel and a color coded wheel. The first two wheels are mounted in wheel wells formed in the top surface of the body and have portions extending past one of the side edges of the body positioned under windows in the top cover exposing a single letter or number. The third wheel is mounted in a wheel well formed in the bottom surface of the body--overlapping and underlying the first two wheel wells--and also has a portion extending past the other edge of the body. The third wheel contains color segments viewed by window apertures formed in the body and the bottom cover plate covering the other surface of the third wheel. Each wheel well has a rear hollow recess and a flexure cavity thus formed. A flexure strip bridges the cavity behind the line of circumference of the well. A pawl mounted on the strip extends into the line of the well into engagement with notches formed on the edge of the wheels. Depressing the wheels depresses the strip into a flexure space behind the strip and allows rotation to expose, index and lock the desired letter, number or color of each wheel. On releasing the wheel, the flexure strip returns to lock the wheel in place.
