Portable electronic device with fast selection
First Claim
Patent Images
1. A portable electronic device with fast selection, comprising:
- a housing;
a movable element provided on a surface of the housing;
a circuit board disposed in the housing;
at least one bonding pad structure formed on the circuit board;
a plurality of conductive elements fixed to the movable element and being in contact with the bonding pad structure, wherein contact positions between the conductive elements and the bonding pad structure are changed by moving the movable element;
a detecting unit disposed on the circuit board and connected to the conductive elements and the bonding pad structure so as to detect an output sensing signal corresponding to the contact positions between the conductive elements and the bonding pad structure, wherein magnitude of the output sensing signal is variable depending on the change of the contact positions between the conductive elements and the bonding pad structure;
a converting unit provided on the circuit board and connected to the detecting unit so as to convert the detected output sensing signal; and
a control unit provided on the circuit board and connected to the converting unit so as to receive the converted signal from the converting unit and output a control signal.

Abstract
A portable electronic device with fast selection is provided, which includes a circuit board; at least one bonding pad structure formed on the circuit board, such as a metal plate; and at least one conductive element provided corresponding to the bonding pad structure, such as a conductive plate. Different impedance signals can be provided by making the conductive element contact different positions of the bonding pad structure, which control the scrolling speed of a scrolling menu for a display of the portable electronic device. This reduces the inconvenience for repeatedly clicking the scroll and provides fast scrolling for function selections
