  • Patent number: 7077539
    Abstract: Disclosed is a stationery holder includes a base having an upper portion, which defines first and second compartments for respectively receiving a roll of adhesive tape and a pen and a card receptacle between the compartments, and a lower portion, which forms a battery chamber for receiving and retaining a battery. An illuminator is mounted in the first compartment and is electrically connected to the battery by a switching device arranged in the receptacle. The switching device includes a fixed conductive contact and a deformable conductive plate that has a spring section engaging a sidewall of the receptacle and floatingly supporting a switching section that is spaced from the contact for a small distance. When a card is inserted between the sidewall and the conductive plate, the spring section deforms and moves the switching section to physically engage the contact thereby forming a closed electrical loop among the illuminator, the battery, and the switching device for powering the illuminator.
