Abstract

A card-type compact data terminal is provided being operatively connectable to a portable electronic apparatus. The data terminal can be removed from the apparatus. The data terminal serves to input and store data for the apparatus while separated from the apparatus. When it is operatively combined with the apparatus, the stored data within the data terminal are processed by the apparatus, even complicated processes, at high speed.

Claims

1. A compact data terminal system comprising:

a portable electronic apparatus, comprising,

a housing,

first means, disposed in said housing, for displaying data,

keyboard means, disposed in said housing, for operating said portable electronic apparatus,

processing means for carrying out operations entered by said keyboard means, and

external terminal storing portion disposed in said housing; and

a card-type external terminal, comprising,

memory means for storing data,

second keyboard means for entering data into said memory means,

second processing means for manipulating data entered by said second keyboard means, and

connector means for electrically and mechanically connecting said card type external terminal to said portable electronic apparatus at said external terminal storing portion.

2. The system of claim 1 wherein said card-type external terminal further comprises a second means for displaying data stored in said memory means, produced by said second processing means or entered by said second keyboard means.

3. The system of claim 2 wherein said portable electronic apparatus further comprises a display window means for making said second means for displaying data visible when said card-type external terminal is connected to said portable electronic apparatus.

4. The system of claim 2 wherein said first means for displaying data comprises a first liquid crystal display and said second means for displaying data comprises a second liquid crystal display.

5. The system of claim 2 wherein said portable electronic apparatus further comprises:

display driving means, connected to said processing means, for driving said first means for displaying data;

second memory means, connected to said processing means for storing data entered into said portable electronic apparatus; and

interfacing means for electrically connecting said processing means to a peripheral device.

6. The system of claim 5 wherein said portable electronic apparatus further comprises a first battery means for supplying power to the elements of said portable electronic apparatus.

7. The system of claim 6 wherein said card-type external terminal further comprises a second battery means for supplying power to the elements of said card-type external terminal.

8. The system of claim 2 wherein said card-type external terminal further comprises second display driving means, connected to said second processing means, for driving said second means for displaying data.

9. The system of claim 8 wherein said card-type external terminal further comprises a second battery means for supplying power to the elements of said card-type external terminal.

10. The system of claim 9 wherein said portable electronic apparatus further comprises a first battery means for supplying power to the elements of said portable electronic apparatus.

11. The system of claim 8 wherein said portable electronic apparatus further comprises:

display driving means, connected to said processing means, for driving said first means for displaying data;

memory means, connected to said processing means for storing data entered into said portable electronic apparatus; and

interfacing means for electrically connecting said processing means to a peripheral device.

12. The system of claim 11 wherein said portable electrionic apparatus further comprises a first battery means for supplying power to the elements of said portable electronic apparatus.

13. The system of claim 12 wherein said card-type external terminal further comprises a second battery means for supplying a power to the elements of said card-type external terminal.
