Abstract

In an inputting apparatus which is manipulated with a finger placed on a manipulating section included in the inputting apparatus, the manipulating section is configured to stimulate the tactile sense of the finger used in the manipulating, enabling to confirm the inputting.

Claims

1. An inputting apparatus for use with a pointer on a display screen, comprising:

a tilt-enabled manipulating section comprising a keytop having an opening therein upon which a finger may be placed to manipulate the inputting apparatus and a tubular-shaped holder held to a lower side of said keytop, said manipulating section including a tactile-stimulating device configured to tactile-stimulate said finger when said pointer is in a predetermined position on the display screen;

a signal-producing section configured to produce a signal in response to a tilt of the manipulating section, which signal causes the pointer on the display screen to be moved, said signal-producing section further comprising;

a permanent magnet disposed at a bottom portion of said manipulating section for tilting movement therewith, and

magneto-electric converting elements which detect a change in a magnetic field corresponding to tilting movement of said permanent magnet, wherein the signal produced by said signal-producing section is based on said change in the magnetic field;

wherein;

said tactile-stimulating device includes a tactile-stimulating element disposed for movement within said holder between a tactile-stimulating position and a non tactile-stimulating position, and wherein said tactile-stimulating element includes a coil and a projecting member positioned with respect to an upper side of said coil, a portion of said projecting member projecting from said opening

when the tactile-stimulating element is in the tactile-stimulating position; and

delivery of a first drive current to said coil generates a first electromagnetic force, using the magnetic field formed by said permanent magnet, which electromagnetic force moves said tactile-stimulating element away from the permanent magnet.

2. The inputting apparatus as claimed in claim 1,

wherein said tactile-stimulating device includes:

a tactile-stimulating element moveable between a tactile-stimulating position and a non tactile-stimulating position,

the tactile-stimulating element being positioned with respect to the permanent magnet such that an electromagnetic force is generated using the magnetic field formed by said permanent magnet, which electromagnetic force moves said tactile-stimulating element to the tactile-stimulating position.

3. The inputting apparatus as claimed in claim 1,

wherein delivery of a second drive current in a direction reverse to said first drive current generates a second electromagnetic force directed towards said permanent magnet, which electromagnetic force moves said tactile-stimulating element towards the permanent magnet.

4. The inputting apparatus as claimed in claim 1,

wherein said tactile-stimulating element is a keytop itself.

5. A manipulating apparatus which incorporates thereinto the inputting apparatus as claimed in claim 1.

6. A manipulating apparatus which incorporates thereinto the inputting apparatus as claimed in claim 1.

7. A manipulating apparatus which incorporates thereinto the inputting apparatus as claimed in claim 1.

8. A manipulating apparatus which incorporates thereinto the inputting apparatus as claimed in claim 1.

11. A manipulating apparatus which incorporates thereinto the inputting apparatus as claimed in claim 4.

9. An inputting apparatus for use with a pointer on a display screen, comprising:

a tilt-enabled manipulating section comprising a keytop having an opening therein upon which a finger may be placed to manipulate the inputting apparatus and a tubular-shaped holder held to a lower side of said keytop, said manipulating section including a tactile-stimulating device configured to tactile-stimulate said finger when said pointer is in a predetermined position on the display screen;

a signal-producing section configured to produce a signal in response to a tilt of the manipulating section, which signal causes the pointer on the display screen to be moved, said signal-producing section further comprising;

a permanent magnet disposed at a bottom portion of said manipulating section

for tilting movement therewith, and

magneto-electric converting elements which detect a change in a magnetic field corresponding to tilting movement of said permanent magnet, wherein the signal produced by said signal-producing section is based on said change in the magnetic field;

wherein;

said tactile-stimulating device includes a tactile-stimulating element for movement within said holder with respect to a top face of said permanent magnet, which tactile-stimulating element includes a coil and a projecting member positioned with respect to an upper side of said coil, a portion of said projecting member projecting from said opening when the tactile-stimulating element is along the top face of said permanent magnet; and

delivery of a first drive current to said coil generates a first electromagnetic force using the magnetic field formed by said permanent magnet, which electromagnetic force moves said tactile-stimulating element to said top face of said permanent magnet.

10. A manipulating apparatus which incorporates thereinto the inputting apparatus as claimed in claim 9.
