Abstract

When a presentation is carried out by employing a projector and a remote printer is utilized, printing operation can be executed in a simple and safty manner. In an information processing apparatus having both a network connection function and either a liquid crystal projector function or a printer function, the information processing apparatus can use, or output data which has been stored in a remote computer based upon a remote terminal operating program which may replace a user interface of the remote computer connected via a network to the information processing apparatus, and a remote terminal server program. The remote terminal server program is stored in the remote computer, and is used to transfer a user interface of the remote computer to the information processing apparatus in correspondence with the remote terminal operating program.

Claims

1. A network terminal system comprising:

an information processing terminal; and

another information processing terminal which is connected via a network to said information processing terminal, wherein;

said information processing terminal includes;

a network connecter which is connected to said network;

a CPU (Central Processing Unit);

an input/output unit of a storage medium which has stored thereinto authentication information;

a storage unit which has stored thereinto a remote terminal operating program for transmitting a signal to said another information processing terminal by being executed by said CPU; and

a bus for connecting said network connecter, said CPU, said input/output unit, and said storage unit to each other, and

said another information processing terminal includes a remote terminal server program capable of using data stored in said another information processing terminal from said information processing terminal in response to the signal transmitted from said information processing terminal by executing said remote terminal operating program.

2. The network terminal system according to claim 1, wherein:

said information processing terminal further includes;

a display input/output unit connected to said bus;

a picture projecting unit connected to said display input/output unit; and

a display unit connected to said display input/output unit, and

said display input/output unit is operable to output data which is transferred from said another information processing apparatus to either one of or both said picture projecting unit and said display unit.

3. The network terminal system according to claim 2, wherein:

said display input/output unit is operable to output images on both said picture projecting unit and said display unit, which are different from each other.

4. The network terminal system according to claim 1, wherein:

said information processing terminal further includes;

a display input/output unit connected to said bus;

a printing process input/output unit connected to said bus;

a display unit connected to said display input/output unit; and

a printing process unit connected to said printing process input/output unit, and

said display input/output unit outputs data transferred from said another information processing apparatus to said display unit, and

said display processing unit is operable to output the data from said printing process unit.

5. The network terminal system according to claim 4, wherein:

in a case that said information processing terminal receives both a print request issued from a further information processing terminal connected via said network and a print request issued from said another information processing terminal, said information processing terminal processes said print request issued from said another information processing apparatus with a top priority.

6. The network terminal system according to claim 1, wherein:

said information processing terminal judges as to whether or not the authentication information acquired from the storage medium, which is entered to said input/output unit, is correct, and

in a case that a judgement result of said authentication information is justified, said information processing terminal is operable to execute said remote terminal operating program.

7. An image output apparatus connected to a network to which at least one information processing terminal is connected, comprising:

a network connecter which is connected to said network;

a CPU (Central Processing Unit);

an input/output unit of a storage medium which has stored thereinto authentication information;

a display input/output unit connected to said display input/output unit;

a picture projecting unit connected to said display input/output unit;

a storage unit which has stored thereinto a remote terminal operating program for transmitting a signal to said information processing terminal by being executed by said CPU; and

a bus for connecting said network connecter, said CPU, said input/output unit, said storage unit, and said display input/output unit to each other,

wherein;

said network connecter transmits a data transfer request of said information processing terminal, which is obtained by executing said remote terminal operating program by said CPU, and

said display input/output unit is operable to output data which is transmitted in correspondence with said data transfer request to either one of or both said picture projecting unit and said display unit.

8. The image output apparatus according to claim 7, wherein:

said display input/output is capable of outputting images on both said picture projecting unit and said display unit, which are different from each other.

9. An image output apparatus according to claim 7, wherein:

said network connecter, said CPU, said display input/output unit, and said picture projecting unit are formed as a first housing, whereas said input/output unit and said display unit are formed as a second housing.

10. The image output apparatus according to claim 9, wherein said image output apparatus owns plural sets of said second housings.

11. The image output apparatus according to claim 9, wherein said first housing and second housing are separate housings.

12. The image output apparatus according to claim 7, wherein:

said image output apparatus judges as to whether or not the authentication information acquired from the storage medium, which is entered to said input/output, is correct, and

in a case that a judgement result of said authentication information is justified, said image output apparatus is operable to execute said remote terminal operating program.

13. An image output apparatus connected to a network to which at least one information processing terminal is connected, comprising:

a network connecter which is connected to said network;

a CPU (Central Processing Unit);

an input/output unit of a storage medium which has stored thereinto authentication information;

a display input/output unit;

a display unit connected to said display input/output unit;

a printing process input/output unit;

a print processing unit connected to said printing process input/output unit;

a storage unit which has stored thereinto a remote terminal operating program for transmitting a signal to said information processing terminal by being executed by said CPU; and
