Abstract

PURPOSE:To display a display screen corresponding to the current situation by associating the display contents of the information processor with the display contents of another device. CONSTITUTION:For example, when the display screen of A moves to an 8th page, the A sends a predetermined code to B - D with an infrared-ray signal to inform them that the display contents of the A move to the 8th page. A microcomputer 4 searches the memory in a part 4 for the contents of the 8th page in response to the signal received from a communication line 5 and displays the contents. When the contents are not stored on the memory in the part 4, the contents are read out of an IC card 3 and displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an information processing device, and particularly to an information processing device having a communication function.

[Background Art] Nowadays, with the spread of portable information processing devices, individuals are increasingly owning and using their own portable devices.

[Problem to be solved by the invention] However, while conventional portable devices are convenient when used at an individual level, in a place where a large number of people gather, such as at a conference, the operation is difficult for each person to use. Because each portable device is independent, even if common data is recorded on each portable device, in order for everyone to view the same screen, each user must use each portable device from time to time. There was the inconvenience of having to operate it.

In addition, one way to resolve this inconvenience is to prepare a separate device such as a large screen so that everyone present can view the data in common, but this method does not require the use of each individual's portable device or device. There was a waste of common data recorded in the system not being utilized.

The present invention is intended to solve these shortcomings, and provides a portable device that can be used effectively even in places where a large number of people gather, such as meetings, and that allows each person to view a screen that is suitable for the occasion. The purpose is to reduce the troublesome operation of each portable device.

[Means and effects for solving the problem] According to the present invention, by providing an information processing device with a means for controlling display content in conjunction with display content of other devices, a user of the device can This allows users to view screens that suit the situation without having to perform operations each time.

[Example] A first example to which the present invention is applied is shown in FIGS. 1 and 2.

This example shows a case where a total of four devices from A to D are used.

FIG. 1 shows an example of the configuration of a portable information processing device, which is composed of a liquid crystal display device 1, a keyboard 2, an IC card 3, a microcomputer 4, and an infrared communication circuit 5. 4 has built-in functions as a normal microcomputer, as well as a drive circuit for 1 and an interface circuit for 2.3.5.

FIG. 2 is an example of a usage pattern using a total of four portable devices A to D.

In this example, A is the master device and BD is the slave device, and the usage pattern is such that the display contents of BD change according to the display contents of A's screen.

Specifically, assume that all portable devices A to D are currently displaying the seventh page of certain document data on their respective screens. Assume that the display screen of A has moved to the 8th page. Then, A transmits a predetermined code to B-D as an infrared signal, informing B-D that the display contents of A have moved to the eighth page.

The internal configuration of BD is as shown in FIG. 1, for example.

The microcomputer 4 searches the contents of the eighth page from the internal memory of the microcomputer 4 based on the signal received by the communication circuit 5, and
Display it on 1. If the contents of page 8 are not recorded in the internal memory of 4, input the necessary data.
It is read from C card 3 and displayed on 1. If the required data is not recorded on the IC card 3, a message such as 8th page data missing will be displayed on the display device 1.
to be displayed.

As another example, assume that the instruction mark displayed on the screen of A moves from the center of the screen to the upper right direction. Using the same procedure, A sends an infrared signal to B-D indicating that A's direction mark has moved and the coordinates of the destination, and B-D, which receives this signal, displays each direction mark on its screen. Move it to the same coordinates as A above.

Through such a procedure, the display screens of B-D can be displayed in conjunction with the screen of A without each user having to operate them each time.

[Other Examples] A second embodiment to which the present invention is applied is shown in FIG.

This example shows that the present invention is not limited to having each portable device be a parent device, but only a child device.

Specifically, it is assumed that all portable devices A to C are currently displaying the total value of certain accounting data for fiscal year 1980. Here, assume that the user of A operates A to display the total value for fiscal year 1981. Then, A informs B and C that the displayed content of A has changed to the total value for 1981. In response to this, the ESC displays the total value for 1981 on each display screen.

Next, assume that the user of B operates B to display the total value for fiscal year 1982. Then, B notifies A and C that the displayed content of B has changed to the total value for 1982. In response to this, the ASC displays the total value for 1982 on each display screen.

In this way, it is also possible to use a mode in which each portable device switches between a master unit and a slave unit as needed, and there is no apparent distinction between a mobile unit and a slave unit.

[Effects of the invention] With the above method, information processing devices can be used effectively even in places where a large number of people gather, such as meetings, and each person can view a screen that is suitable for the occasion. It becomes possible to realize a portable device that can reduce the troublesome operation of each portable device.
