Portable telephone set

Claim 2

A portable telephone set comprising: display for displaying information associated with a call; a main body structure for mounting said display means; detecting means for detecting inclination of said main body structure,said detecting comprising a gyro; and control for controlling a power supply for said display depending upon the inclination detected by said detecting means.

Claim 3

A portable telephone set as set forth in claim 1, wherein said control means shut off the power supply for said display when said detecting means detects the main body at a substantially vertical position.

Claim 4

A portable telephone set as set forth in claim 1, wherein said control means initiates the power supply for said display means when said detecting means detects the main body at a substantially horizontal position.

Claim 5

A portable telephone set as set forth in claim 1, wherein said control shuts off the power supply for said display when said detecting means detects the main body at a substantially vertical position and initiates the power supply for said display means when said detecting detects the main body at a substantially horizontal position.

Claim 6

A portable telephone set comprising: call origination control responsive to a dialing operation for controlling call origination; reception control responsive to reception of a call for controlling reception; display for displaying information associated with call origination and reception; a main body housing said call origination control, means, said reception control and said display means; detecting for detecting inclination of said main body; and control for controlling a power supply for said display means, said control being responsive to said detecting means detecting a substantially horizontal position of said main body for initiating the power supply for said display.

Claim 7

A portable telephone set comprising: call origination control responsive to a dialing operation for controlling call origination; reception control responsive to reception of a call for controlling reception; display for displaying information associated with call origination and reception; a main body housing said call origination control, means, said reception control and said display means; detecting for detecting inclination of said main body; and control for controlling a power supply for said display means, said control being responsive to said detecting means detecting a substantially horizontal position of said main body for initiating the power supply for said display.

Claim 8

A portable telephone set as set forth in claim 5, wherein said control is responsive to said detecting means detecting a substantially vertical position for speaking after the dialing operation, for shutting off the power supply for said display.

Claim 9

A portable telephone set as set forth claim 5 wherein said detection means comprises a gyro.

Claim 10

A portable telephone set comprising: a call origination controller responsive to a dialing operation for controlling call origination; a reception controller responsive to reception of a call for controlling reception; a display unit for displaying information associated with call origination and reception; a main body housing said call origination control means, said reception control and said display means, said main body having an operation button array for dialing operation, call origination and reception; an inclination detector incorporated in said main body for detecting said main body in a predetermined range of inclination magnitude indicating speaking condition; and a display controller for controlling a power supply for said display unit, said control being responsive to said inclination, detector detecting said main body within said predetermined range of inclination magnitude for shutting down the power supply.

Claim 11

A portable telephone set comprising: a call origination controller responsive to a dialing operation for controlling call origination; a reception controller responsive to reception of a call for controlling reception; a display unit for displaying information associated with call origination and reception; a main body housing said call origination control means, said reception control and said display means, said main body having an operation button array for dialing operation, call origination and reception; an inclination detector incorporated in said main body for detecting said main body in a predetermined range of inclination magnitude indicating speaking condition; and a display controller for controlling a power supply for said display unit, said control being responsive to said inclination, detector detecting said main body within said predetermined range of inclination magnitude for shutting down the power supply.

Claim 12

A portable telephone set as set forth in claim 8, wherein said display controller is responsive to said inclination detector detecting the inclination magnitude of said main body out of said predetermined range for initiating the power supply when at least one of a plurality of buttons in said operation button array is operated.
