ABSTRACT:
Food consumption monitor comprising a simple mechanical calculator integrated into a diet guidebook. The calculator includes a manually operable rotary dial with a scale pointer on it, a base for the dial, a means for rotatably mounting the dial to the base, a finger stop attached to the base near the dial, and a set of numerals which are printed in consecutive order on the base near the dial and which are equidistant from the dial's rotary axis. The dial has a set of finger holes or dimples which are equidistant from the dial's rotary axis. The dial's scale pointer is a visually distinctive feature on the dial, such as an annular rim around one of the holes, which rotates with the dial in close proximity to the set of numerals. The base includes a molded plastic casing which partially encloses the dial. This casing includes an axle, a stationary hub, and a support arm for rigidly coupling the hub to a wall of the casing, wherein these three components are the means for rotatably mounting the dial. The calculator's plastic casing is attached to the interior face of the guidebook's hardbound cover. This diet guidebook includes data related to some food parameter, such as grams of fat. The user registers his consumption of this parameter by rotating the dial by an amount specified in the guidebook.
