Abstract

The display device for a telephone set is designed to be capable of storing in advance the telephone number, person'"'"'s name, company name, etc. of any desired (one or more) party (subscriber) through the numeric data input means and character data input means which typically use the dial keys of the telephone set, and proper software keys, recognizing the special dial operation made by the user via the specific software keys for telephoning, checking the memory whether the data corresponding to the dialed number is stored, reading the data from the memory if stored, and displaying in the display unit preferably giving the priority to the character data showing the name, company name, etc.

Claims

1. A telephonic display device comprising:

numeric data input means for inputting numeric data;

character data input means for inputting character data;

a first memory for storing said numeric and character data;

a display unit for displaying said numeric and character data;

a first software key for causing said numeric and character data to be stored in said first memory;

first control means for generating address signals based on special number data entered through said numeric data input means in association with telephone number data and character data of a party to be called which is entered through said numeric data input means and said character data input means, respectively, in association with operation of said first software key, and for storing said entered telephone number data and character data in said first memory for said party based on said address signal;

a second software key for accessing any data stored in said first memory; and

second control means for generating an address signal based on the special number data when said special number data is entered through said numeric data input means in association with operation of said second software key, for identifying based on said address signal whether said telephone number data and said character data corresponding to said special number data are stored in said first memory, for reading said telephone number data and said character data when the telephone number data and the character data are stored in said first memory, for displaying said stored data on said display unit, and for transferring said telephone number data to said main body circuit of said telephone set.

2. A telephonic display device of claim 1 wherein said numeric data input means and said character data input means comprise a keyboard for dialing operation, and said display device comprises a mode key for switching between a numeric data input mode and a character data input mode.

3. A telephonic display device of claim 1 wherein said second control means causes said display unit to display selectively either said telephone number data or said character data.

4. A telephonic display device of claim 3 wherein said second control means causes said display unit to display said character data in preference to said telephone number.

5. A telephonic display device of claim 4 wherein said display device has a third software key for selecting the data to be displayed, the operation thereof enabling said second control means to control the switching of data to be displayed on said display unit.

6. A telephonic display device of claim 5 wherein said second control means, when said second control means cannot display said selected character or telephone number data in its entirely at a time, causes said display unit to display a mark indicating this fact together, the remainder being caused to be displayed on said display unit based on the operation of said third software key.

7. The telephonic display device of claim 4 wherein said second control means has a timer means for controlling the selecting of data to be displayed on said display unit based on the timing operation of said timer means.

8. The telephonic display device of claim 7 wherein said second control means, when said selected character data or telephone number data cannot be displayed on said display unit in its entirety at a time, causes a mark indicating the fact to be displayed together on said display unit, the remainder being caused to be displayed according to the timing operation of said timer means.

9. The telephonic display device of claim 1 wherein said first control means is responsive to said special number data which is abbreviated telephone number data.

10. A display telephone including a main body for transmitting dialing signals to an exchange, a display unit for displaying stored data, and a memory in which is stored at least one type of data with respect to parties to be called including character type data identifying a party to be called, telephone number type data representative of the telephone number of a party to be called, and special number type data having a smaller number of digits than the telephone number data and used as an index of stored telephone number data, said display telephone comprising;

a first function key used for displaying data stored in the memory and, if telephone number type data is stored in said memory, for calling a party corresponding to said telephone number type data; and

control means for searching the memory, when special number type data is inputted following the operation of said first function key, for a memory address corresponding to inputted special number type data and, if data of any type is stored at said address of the memory, for transferring said stored data into said display unit as well as, if telephone number type data is stored at said address of said memory, transferring said telephone number type data into the main body to call a party corresponding to said telephone number type data.

11. The display telephone as claimed in claim 10 wherein said display unit is capable of displaying a predetermined number of digits in a single line.

12. The display telephone as claimed in claim 11 wherein said control means, when two or more types of data are stored at said address out of said character data, telephone number data and special number data, causes either one type of said stored data to be transferred into said display unit.

13. The display telephone as claimed in claim 12 wherein said control means causes said character data to be transferred into said display unit in preference to other types of data if said character data is stored at said address of the memory.

14. The display telephone as claimed in claim 13, further comprising a second function key for instructing the switching of display content on said display unit, the operation of said second function key causing said control means to control the switching of data to be transferred into said display unit.

15. The display telephone as claimed in claim 14 wherein said control means, when said selectively transferred data cannot be displayed in its entirety at one time, causes said display unit to display a mark indicating this fact together with the remaining undisplayed data being transferred into said display unit in response to the operation of said second function key.

16. The display telephone as claimed in claim 15 wherein said control means has a timer means and controls the switching of data to be transferred into said display unit based on the timing operation of said timer means.

17. The display telephone as claimed in claim 16 wherein said control means, when said selectively transferred data cannot be displayed in its entirety at one time, causes said display unit to display a mark indicating this fact together with the remaining undisplayed data being transferred into said display unit based on the timing operation of said timer means.

18. The display telephone as claimed in claim 17 wherein said control means, when at least one of the telephone number data and the special number data is not stored, causes said display unit to display a mark indicating this fact.
