Abstract

This invention relates to a namecard holder and in particular to one including an electrical circuit and a control switch disposed at one side of a notch of an open end thereof. The control switch has a conducting plate and a curved spring leaf which are normally in contact with each other. The spring leaf is provided with a lower end for preventing namecards from leaving the holder unintentionally. When a namecard is partially drawn out of the holder, the conducting plate will be separated from the spring leaf thereby activating the electrical circuit and as the namecard is completely drawn out of the holder, the conducting plate will contact the spring leaf again consequently actuating a musical or speech IC and a pressure electrical vocal producer to send out music or speech to appeal the visitor'"'"'s attention.

Claims

1. A namecard holder formed by a body member having an open end, said open end having a notch formed therein for removing one of a plurality of namecards stored therein, comprising:

a control switch disposed in a portion of a recess formed within said body member adjacent said notch at said open end, said control switch including a conducting plate in conductive contact with a spring leaf having a curved contour, said spring leaf having a lower end for preventing said plurality of namecards from leaving the namecard holder unintentionally;

electrical means electrically coupled to said control switch for generating control signals responsive to said control switch, said electrical means including a power source coupled to a transistor switching circuit disposed within said recess for generating a first of said control signals responsive to separation of said spring leaf from said conducting plate, said separation being responsive to a partial withdrawal from said body member of one of said plurality of namecards, said transistor switching circuit generating a second of said control signals responsive to said spring leaf returning to conductive contact with said conducting plate, said return of conductive contact being responsive to said namecard being fully withdrawn from said body member; and

,

means for audio generation coupled to said transistor switching circuit, said means for audio generation including (1) a music or speech integrated circuit disposed within said recess for generating an audio electrical signal of predetermined duration responsive to receipt of said second control signal subsequent to said first control signal, and (2) a pressure electrical vocal producer disposed within said recess and coupled to said integrated circuit for transducing said audio electrical signal to a sonic signal output.
