Abstract: An object of the present invention is to convert a voice to a character string and output attribute data associated with the character string. The central controller of the data processing apparatus converts a voice entered from the voice input unit through the voice/character code conversion processing to a character string. Then, any date and time part of the character string are detected through the date detection processing and the time detection processing and the detected date and time part are converted to predetermined date and time words through the date conversion processing and the time conversion processing. Finally, the converted date and time are associated to a voice and a character string as attribute data through the monitor controlling and stored in the schedule memory as schedule data. Consequently, the date and time are associated to a voice and a character string automatically.

Abstract: If an unnecessary sentence is included in data tabulated at a display, a head address is prepared in a memory region for storing a new data group. A counter m indicating a function and a counter n indicating a data number corresponding to the function are initialized. A determination whether or not the data (Y(m)) is necessary is made for every function (X(m, n)), and the only necessary data is stored in the memory. This operation is performed to check four functions and 100 pieces of data for each of the four functions. When the operation is completed, the resultant data is stored as a set of data in the memory.

Abstract: An electronic device with a calendar function having an input device, so that a desired date can be entered in the electronic device. The day of the week that January 1st falls on in the year corresponding to the desired date is determined. The ordinal number of a week in which the entered desired date falls is determined dependent on the day January 1st falls on. For example, if January 1st is between a first day of the week and a fourth day of the week, the week corresponding to January 1st is deemed as the first week in the year, if January 1st is between a fifth day and a seventh day of the week, the week following the week to which January 1st belongs is deemed as the first week of the year. A display is provided displaying the ordinal number of the week of the year in which the entered desired date falls.

Abstract: An electronic device is provided with a calendar function such that it is possible to display one or more schedules. The electronic device includes an input device which receives data representing starting and ending times. This data is displayed in graphic format to illustrate the starting and ending times of the schedule.

Abstract: An electronic world clock device indicates a time in connection with a designated region based on a time difference in a reference region to be stored, and comprises clock means for counting a present time in a specified home region and memory means for storing various regions and names of the countries and the time differences corresponding to said various regions in the world, and said designated region and the name of the country where said designated region belongs are stored at the same time, so that said designated region as well as the name of the corresponding country and/or a time difference between two different regions in the world are indicated at the same time on the basis of the time difference in said reference region.
