Abstract
A truck driver logging device including a display adapted to depict a time log graph. The time log graph comprises a plurality of rows each corresponding to a duty pertinent to the daily activities of a truck driver. The time log graph further comprises a multiplicity of columns with vertically aligned tick marks depicted thereon. Each tick mark corresponds to a specific time within a twenty-four hour period. A plurality of duty buttons are adapted to graph a line within the corresponding row between two of the tick marks thus displaying the specific time of the day allotted to the corresponding duty. The beginning of a specific line in a row is defined merely by pressing duty key at the beginning of the time allotted to the associated duty and the end thereof is afforded by the subsequent depression of a different duty key. A control mechanism is adapted to automatically calculate and display the time graphically depicted for each duty and further to automatically calculate and display a running weekly total of time entered during a present week for each duty.
