Abstract
Abstract A novel tape-length selector or control mechanism for electrical tape-dispensing machines comprising a head cover casting supporting on the top a plurality of tape-length selector pushbuttons disposed in a circle, a novel 16-pole switch supported beneath said casting for selective actuation by said pushbuttons, a diode logic board or diode selective switching board disposed beneath and secured to the casting supporting the said switch in cooperative relation for selective energization thereby, a computer board assembly supported beneath the diode logic board including a binary multistage counter which is conditioned for counting by said diode logic board upon selective energization thereof, a normally open reed-type pulse switch electrically connected with the counter, a measuring wheel rotatably engaged by fed tape, a permanent magnet mounted for rotation by the measuring wheel adapted to close the pulse switch twice per revolution of the measuring wheel, a transformer for supplying low voltage to a rectifier for direct current to the counter and diode logic board, an on-off and random operation switch, and integrating circuitry.
