1. A multi-direction input device, comprising:
- a directional wheel which has an axle, a coaxial gear located at a first side thereof and a coaxial annular inclined surface located at a second side thereof, and a rotational degree-of-freedom for rolling forward and rolling backward and two moving degree-of-freedom for moving sideward and downward to perform click operation;
a sliding member which is located at the second side of the directional wheel and includes an inclined surface corresponding to the coaxial annular inclined surface such that when the directing wheel is moved downward the sliding member is slid by directing of the coaxial annular inclined surface and the inclined surface; and
a plurality of electrodes, includinga first electrode, a second electrode and a third electrode that are located at the second side of the directional wheel such that when the directional wheel is moved downward the sliding member slides to form electric connection between the first electrode and the second electrode;
when the directional wheel is moved towards the second side the axle forces the first electrode to form electric connection with the third electrode;
a fifth electrode, a sixth electrode and a seventh electrode that are located at the first side of the directional wheel, the fifth electrode and the seventh electrode being interposed by a movable contact which is conductive and elastic, and has one end electrically connected to the sixth electrode and another end constantly in contact with a gear surface of the coaxial gear such that in regular conditions the movable contact is not connected to the fifth electrode or the seventh electrode;
when the directional wheel rotates the gear surface moves the movable contact to connect the fifth electrode or the seventh electrode; and
a fourth electrode and an eighth electrode that are located at the first side of the directional wheel such that when the directional wheel is moved towards the first side the axle forces the fourth electrode and the eighth electrode to form electric connection.

Abstract
A multi-direction input device for computers includes a directional wheel, a sliding member and a plurality of electrodes. The directional wheel has a rotational degree-of-freedom and two moving degree-of-freedom to be moved downwards, perform forward rolling, backward rolling and sideward moving thereby to connect corresponding electrodes to generate corresponding signals. In regular conditions the sliding member can be in cooperation with a movable contact to support the directional wheel. When the directional wheel is moved downwards the sliding member drives a corresponding electrode to generate a click signal.

12. An input device to trigger an encoder to generate a click signal, comprising:
-
a directional wheel which is movable downwards and has an axle and a coaxial annular inclined surface; a sliding member which has an inclined surface corresponding to the coaxial annular inclined surface and an actuation contact;
when the directional wheel is moved downwards the sliding member slides by jointed directing of the coaxial annular inclined surface and the inclined surface; anda first electrode and a second electrode located at a same side of the directional wheel, the first electrode and the second electrode being electrically connected to the encoder, the first electrode having a conductive second elastic reed, the second electrode being located at an outer side of one end of the actuation contact, when the directional wheel is moved downwards and the sliding member slides the actuation contact is moved towards the second elastic reed to force the second elastic reed in contact with the second electrode such that the first electrode and the second electrode form electric connection to trigger the encoder to generate a click signal, in regular conditions the second elastic reed being not in contact with the second electrode. - View Dependent Claims (13, 14, 15)
