TRACK WHEEL WITH REDUCED SPACE REQUIREMENTS
First Claim
1. An input generating device positioned at a side of an electronic device comprising:
- a core formed to have two parallel planar surfaces, said core including a peripheral edge around the entirety of said core; and
a flexible track slidably engaged with the core for movement only in a first direction and a second direction, where said second direction is opposite said first direction;
whereby a first input is generated by sliding movement of the flexible track relative to the core in said first direction.

Abstract
An input generating device for use in a hand held electronic device having a housing includes a core formed in a planar and semicircular in shape, forming a peripheral edge extending around said core and a track slidably engaged with the peripheral side edge. A curved portion of the peripheral edge extends outwardly from the housing allowing access thereto by the user. A first input is generated by sliding movement of the flexible track relative to the core. First input detection means, such as a turns encoder switch detects the sliding movement of the track. The core is depressibly mounted within the housing, generating a second input when the core is depressed. A second input detection means, such as a tactile contact switch detects depression of the core.

12. An input generating device for use in a hand held electronic device and positioned at a side of a housing thereof, said input generating device comprising:
-
a core formed to have two parallel planar surfaces and a peripheral edge extending around said core, said core mounted within said housing, a flexible track slidably engaged with the core for movement only in a first direction and a second direction, where said second direction is opposite said first direction, whereby a first input is generated by sliding movement of the flexible track relative to the core in said first direction, a portion of the core and track protruding outside said housing allowing access thereto by a user, the input generating device including a first input detection component for receiving said first input generated by said sliding movement of the track. - View Dependent Claims (13, 14, 15, 16, 17, 18)
