Abstract
An illuminated paper tray having a main housing with a well for storing individual sheets of paper. The rear portion of the housing incorporates electrical circuitry for energizing and de-energizing a light bulb, which light bulb illuminates the well of the housing storing the paper via a separating partition of translucent plastic. The illumination of the light bulb is controlled by the insertion or removal of a pen into a through-hole formed in the rear portion of the housing. When the pen is inserted in the housing, for storage, the light bulb is de-energized, whereas upon removal of the pen from the housing for writing, the light bulb is illuminated. The tip of the pen passing through the through-hole and into the interior of the rear portion of the housing controls a pivot plate which has mounted at its freely pivoted end a camming surface which forces a portion of the conducting electrical strips out of contact with each other to thereby break the circuitry between the batteries and the light bulb, while the removal of the pen causes the return of the pivot plate to its normal horizontal position, and the camming surface out of contact with the corresponding portions of the conducting strip of the circuitry, to thereby allow for the normal closed contact state of these conducting strips to thereby allow for the energization of the light bulb.
