Abstract
Abstract A clock apparatus comprising an EEPROM 8 to store a shipping area code, an internal clock 12, a time button 2, and a liquid crystal display section 5. The time of the internal clock 12 is set by the time button 2, the shipping area code is set by the EEPROM 8, and the area information is set on the basis of the shipping area code. When the shipping area coincides with the purchase area, by merely setting the time of the purchase area, the world time can be easily obtained.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
234 words
A clock apparatus comprising: a central controller; first memory means connected to said central controller for storing a preset area code, said preset area code corresponding to a shipping location where said clock apparatus is to be shipped; second memory means connected to said central controller; clock means connected to said central controller for generating time information for said preset area code; data input means connected to said central controller for allowing a user to change said preset area code to a present area code representing a present location of said clock apparatus which is different from said shipping location, said data input means storing said present area code in said second memory when said present area code differs from said preset area code; a correction circuit for adjusting said time information from said clock means to reflect a time at said present location of said clock apparatus in said present area code; and display means connected to said central controller for displaying said time information; wherein said central controller checks said second memory means to determine whether said present area code has been entered and supplies said display means with said time information from said correcting circuit for said present area code if said present area code has been entered and supplies said display means with said time information for said preset area code if said present area code has not been entered.
Claim 2
Dependent Claim
234 words
A clock apparatus comprising: a central controller; first memory means connected to said central controller for storing a preset area code, said preset area code corresponding to a shipping location where said clock apparatus is to be shipped; second memory means connected to said central controller; clock means connected to said central controller for generating time information for said preset area code; data input means connected to said central controller for allowing a user to change said preset area code to a present area code representing a present location of said clock apparatus which is different from said shipping location, said data input means storing said present area code in said second memory when said present area code differs from said preset area code; a correction circuit for adjusting said time information from said clock means to reflect a time at said present location of said clock apparatus in said present area code; and display means connected to said central controller for displaying said time information; wherein said central controller checks said second memory means to determine whether said present area code has been entered and supplies said display means with said time information from said correcting circuit for said present area code if said present area code has been entered and supplies said display means with said time information for said preset area code if said present area code has not been entered.
Claim 3
Dependent Claim
16 words
The clock apparatus as set forth in claim 1, wherein said first memory means comprises EEPROM.
Claim 4
Dependent Claim
16 words
The clock apparatus as set forth in claim 1, wherein said second memory means comprises RAM.
Claim 5
Dependent Claim
41 words
The clock apparatus as set forth in claim 3, wherein said first memory means comprises EEPROM and said central controller transfers said preset area code from said EEPROM to said RAM when checking whether said present area code has been entered.
Claim 6
Dependent Claim
17 words
The clock apparatus as set forth in claim 1, wherein said display means comprises an LCD display.
