Data generating device and a portable apparatus provided with a data generating device

A data generating device comprising:

• a first date data generator which generates first date data;
• a memory which stores a relationship between the first date data and date data of a field place;
• and
• a second date data generator which determines, based on the first date data, where a field place is, and generates second date data based on the first date data and the relationship.

A portable apparatus comprising:

• a basic date data generator which generates basic date data of a basic place;
• an input section through which place data concerning places and travel schedule data are input;
• a memory which stores input place data and schedule data in connection with the input place data;
• and
• a field date data generator which determines, based on the place data and the schedule data stored in the memory, where a field place is, and generates date data of a determined field place based on the basic date data and the determined field place.

A portable apparatus comprising:

• a first date data generator which generates first date data;
• an input section through which date data of places are input;
• a memory which stores a relationship between the first date data and the date data of places;
• and
• a second date data generator which determines, based on the first date data, where a field place is, and generates second date data based on the first date data and the relationship.

A camera comprising:

• means for generating basic date data based on a standard time of a first place;
• means for displaying date data;
• first means for storing data on a second place and data on travel schedule for the second place;
• second means for storing data on time difference between the standard time of the first place and a standard time of the second place;
• means for changing generated basic date data into field date data of the second place based on the time difference data stored in the second storing means;
• means for determining, based on the travel schedule data, whether generated basic date data corresponds to a traveling period of the second place;
• and
• means for controlling the displaying means to display the field date data of the second place when the generated basic date data is determined to correspond to a traveling period of the second place.

A portable apparatus comprising:

• a calendar unit including a time counter;
• a display unit which displays at least one of a date and a time based on the calendar unit;
• a first memory which stores data on a travel schedule including a stay place and a stay period;
• a second memory which stores data on a time lag between a departure place and the stay place;
• and
• a controller which controls the display unit to display at least one of a date and a time of the stay place based on the travel schedule data stored in the first memory and the time lag data stored in the second memory.

A portable apparatus comprising:

• a calendar unit including a time counter;
• a display unit which displays at least one of a date and a time based on the calendar;
• a first memory which stores data on a travel schedule including a stay place and a stay period;
• a second memory which stores data on a time lag between a departure place and the stay place;
• and
• a time changer which changes the at least one of the date and the time based on the travel schedule data stored in the first memory and the time lag data stored in the second memory, and controls the display unit to display at least one of a changed date and a changed time.
