Portable electronic instrument including at least one control member arranged for also transmitting electric signals
First Claim
1. A portable electronic instrument including a case and a user interface for selecting the functions of said portable electronic instrument, said user interface including at least a first control member mounted to be mobile in an assembly orifice arranged in said case so as to have a translation travel along an axis of actuation, said control member being able to be actuated by pressure to be brought from a position called the non pushed-in position to a position called the pushed-in position and to generate in response a control signal,said control member including an electrically conductive stem which passes through said assembly orifice and which includes first and second ends opening out respectively inside and outside said case, said stem being adapted to allow transmission of electric signals from or to the portable electronic instrument, when said control member is brought into said pushed-in position,wherein said electronic instrument further includes means for bringing the stem of the control member to a determined electric potential when said control member occupies said non pushed-in position and for interrupting the connection of the stem of the control member to said determined electric potential when said control member occupies said pushed-in position and for thus allowing transmission of said electric signals from or to the portable electronic instrument.

Abstract
There is disclosed a portable electronic instrument (1) including a case (2) and a user interface (11 to 15) for selecting the functions of said portable electronic instrument, this user interface including at least a first control member (11) mounted to be mobile in an assembly orifice (3a) arranged in the case so as to have a translation travel along an axis of actuation (X—X), said control member being able to be actuated by pressure to be brought from a position called the non pushed-in position to a position called the pushed-in position and to generate in response a control signal (SEL). The control member includes an electrically conductive stem (100) which passes through the assembly orifice and which includes first and second ends opening out respectively inside and outside the case, said stem being adapted to allow transmission of electric signals from and/or to the portable electronic instrument, when the control member is brought into said pushed-in position. This electronic instrument further includes means (3, 30, 40; 35, 40) for bringing the stem of the control member to a determined electric potential when the control member occupies the non pushed-in position and for interrupting the connection of the stem of the control member to the determined electric potential when the control member occupies said pushed-in position and for thus allowing transmission of said electric signals from and/or to the portable electronic instrument.

12. A control device for a portable electronic instrument, including at least one control member mounted to be mobile in a support so as to have a translation travel along an axis of actuation, said control member being able to be actuated by pressure to be brought from a position called the non pushed-in position to a position called the pushed-in position,
said control member including an electrically conductive stem arranged for allowing transmission of electric signals from or to the portable electronic instrument when said control member is brought into said pushed-in position, said control device including a first electric contact, electrically insulated from said stem, and capable of being actuated by the control member to generate a control signal in response, said control device further including a second electric contact capable of being actuated by the control member to establish, in the pushed-in position, an electric contact between said stem and an input/output line of the portable electronic instrument forming a transmission line of said electric signals, wherein said control device, in the non pushed-in position, said second electric contact establishes an electric connection between said stem and a determined electric potential thus preventing accumulation of electric charges on said stem.
