Abstract

PURPOSE:To set the complete display time of idle screen information constant by starting a timer when the display action of screen information is completed. CONSTITUTION:When screen information is displayed as idle screen information, the timer is set to start when the display action is completed and display is set to continue until the time of the timer is up. When the time of the timer is up, the display action of preceding screen information starts. Even if a time necessary for the display of screen information respectively differ, the time when they are completely displayed can be set constant. The display completion of screen information is judged by reading codes added to the last packet when screen information transmitted from a center is received and displayed. For displaying screen information stored in the hard disk, etc., in an equipment, judgement can be executed by a read address, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a videotex terminal device that sequentially displays a plurality of idle screen information while a user is waiting for an operation.

(b) Summary of the Invention The Videotex terminal device according to the present invention is provided with a timer that starts when the display operation of idle screen information is completed,
The screen information continues to be displayed until this timer times up, and then the next screen information starts to be displayed. As a result, the time period during which one piece of idle screen information is displayed is made the same.

(C) Conventional technology Videotex terminal devices such as the Captain System display specific idle screen information during waiting periods when the user is not performing any operations in order to call the user's attention or to convey some information. There is something that is displayed. Generally, idle screen information consists of multiple pieces of screen information, and the screen is automatically switched by a timer. (d) Problems to be solved by the invention By the way, the number of characters and dots included in the screen information There is a considerable difference in the amount of data constituting one piece of screen information depending on the amount of pattern line drawings, etc. For this reason, if the amount of data is small, it will take less than one second to complete the screen information display after starting, but if the amount of data is extremely large, it will take about 10 seconds. Currently, there is a considerable difference in the display ownership time. However, in conventional Videotex terminal equipment,
The timer that controls the display time of idle screen information is set so that the time from the start of displaying screen information to the start of displaying the next screen information is constant, so in the case of screen information with a large amount of data, regardless of the amount of data. There was a problem that the time for which the image was completely displayed was shortened.

This invention was made in view of these problems.
It is an object of the present invention to provide a videotex terminal device that makes the complete display time of idle screen information constant.

(Means for Solving Problem e1) This invention provides a Videotex terminal device that sequentially displays a plurality of pieces of screen information as idle screen information during an operation waiting time. The present invention is characterized in that a timer is provided that starts when the display operation is completed, and means is provided for starting the display operation of the next screen information when the timer times out.

(f) Operation When the Videotex terminal device of the present invention is displaying screen information as idle screen information, a timer is started when the display operation is completed, and the display is continued for lta 3Ft until this timer times up. When the timer times up, the next screen information display operation starts. As a result, even if the time required to display the screen information varies, the time during which the screen information is completely displayed can be made constant. Note that when screen information sent from the center is received and displayed, the completion of displaying the screen information is determined by reading the code attached to the final packet, which is stored on the hard disk, etc. in the device. When displaying screen information that is currently being displayed, it is sufficient to make a judgment based on the read address, etc.

(Bright Embodiment Figure 2 is an external view of a Videotex terminal device that is an embodiment of the present invention.A CRTI that displays screen information is installed on the operation panel at the front of the device, and below this CRTI. is provided with a keyboard 2. The keyboard 2 includes a search key that is pressed when searching screen information.

In addition, a card insertion element 3 and a card insertion indicator 4 are provided on the right side of the CRTI, and a hard copy 1 non-exit 5 for ejecting a hard copy is provided below. It is a block diagram of the control part of. A CPU 12, which is a control device, is connected to a memory 1) that stores programs, data, etc. via a bus. A printer 12 for hard copy printing, a display 17 including the CRT 1. Display RAM 13 for inputting screen data.
A communication control unit 14 for communicating with the biotech center via the NCU/modem 18. An input control section 15 for controlling input of the keyboard 2. A card league control section 16 that controls the card reader 19 and a hard disk device 20 for storing idle screen information are connected within the device.

FIGS. 4(A) and 4(B) show the hard disk device 2.
0 and memory 1). First, the same figure (A
), a plurality of pieces of idle screen information are stored in the hard disk drive 20 in correspondence with their screen numbers.

In addition, in the same figure (I3), a pointer (M2) indicating the screen number of screen information to be displayed is stored in the RAM section of memory 1).
) is set. This pointer is added and updated when the screen information pointed to is displayed.

FIG. 1 is a flowchart showing the operation of the control section. First, nl reads the screen number from the pointer and stores the screen information corresponding to that screen number on the hard disk drive ff2.
Reading starts from 0 and starts displaying (n2). Display is performed by reading data from the beginning and sequentially displaying it on the CRT. n indicates that this display operation has been completed.
If the judgment is made in step 3, the subtraction in the timer area (M3) is started and the timer is started (n4), and the process continues until time-up or the search key is pressed in n5. Wait at n6. If the time is up, the process returns from n5 to nl to start displaying the next screen information, and if the search key is pressed, the process proceeds from n6 to nl to perform information search processing. As described above, the completion of the display operation can be determined by checking that the screen information read address has reached the last address.

n5 corresponds to "means for starting the display operation of the next screen information when the timer times up" of the present invention.

In this embodiment, the idle screen information is stored in the hard disk drive in the device, but instead of the screen information, the screen number of the screen information to be displayed as the idle screen information is stored, and the screen number of the screen information to be displayed as the idle screen information is stored, and the screen number can be pointed to with the pointer. The idle screen information may be received and displayed by accessing the center using the indicated screen number.

(h) Effects of the Invention According to the present invention, by starting the timer when the screen information display operation is completed, there is a difference in the amount of data composing each screen information, which is required for display. Even if the time is different, the time you want to display it completely can be the same. This allows all screen information to be displayed for the same amount of time, making it easier to understand what is being viewed.
