Abstract
A disc-like sheet of pressure-sensitive material rests on a turntable rotatably mounted on a housing. The sheet has spaced scale markings there on around its circumference indicating units of time. A stylus arm is movably mounted on the housing in proximity with the turntable and has a stylus affixed to, and extending from, its free end and abutting the sheet of material at its axial area. The housing has a clock motor and solenoid electrically connected between an electrical appliance and a source of electrical energy. The motor rotates the turntable one revolution in a predetermined period of time. The solenoid moves the stylus to the circumferential area of the sheet during the operation energization and of the appliance to record such operation in the circumferential area during the time of operation. The stylus is in the axial area of the sheet during deenergization of the appliance to record inoperativeness of the appliance in the axial area.
