Also, the key 21213 (# 1 to #n) is set as a means for the read / write device 12 to read out image data and / or character data, and if key collation with the telephone 1 succeeds, the image data and / or Alternatively, a function of displaying character data in the display area 141 is provided.

The telephone 1 changes the type of the IC card 2 via the read / write device 12 into an image recordable card code 2.
By determining in step 111 that the IC card 2 is an image recording card, the plurality of images are displayed in a time-division manner on the display area 141 during a call.

As shown in FIG. 1C, the keys 21213 (# 1 to #n) stored in the storage device 13 are:
It has a function of updating the key in accordance with the installation environment of the telephone 1 by remote control via a communication line. Of the plurality of image data and / or character data recorded on the IC card 2, it is possible to prevent the display of message data that failed to match with the key stored in the storage device 13 of the telephone.

The internal memory configuration when the IC card 2 according to the embodiment of the present invention is used is such that three screens of image data and / or character data 21211 (# 1 to # 3) are stored in the applicable IC chip 21. Have recorded. The display area 141 is divided into four parts in the horizontal direction, and characters are displayed on each line. Hereinafter, a case where four lines of text are displayed in the display area 141 will be described as an example.

FIG. 2 is a memory map of the image file 2121 (# 1). The data of each address (# 0 to # 443) is composed of 1 byte × 16, that is, a total of 16 bytes.

The display time 41 indicates the display time of the image displayed in the display area 141, and is recorded as 1-byte binary data. If "1" is recorded, the display time is 10 seconds, if "2" is recorded, the display time is 20 seconds, and "3".
Is recorded, the display time is 30 seconds.

The line type code 42 indicates the presence or absence of a character in each line and the presence or absence of a telop display, and is recorded as 1-byte binary data. In the present embodiment, the message display has four lines, and each line is divided into those with characters and those without characters. In addition, if there is a character, there is a telop
Divided into none. Therefore, for one line, "with text (with telop)""with text (without telop)"
It is divided into three patterns of "no character". Therefore, as shown in FIG. 3, there are 3 ⁴ = 81 sets of setting patterns in four rows.

The display mode code 43 is a code for distinguishing whether the image displayed in the display area 141 is a text display or a bitmap display, and is recorded as a one-byte binary code.

The first line character attribute 51 indicates the attribute of the character displayed on the first line of the display area 141, and is displayed as 1-byte binary data. In the present embodiment,
"0" is the default, "1" is underlined,
"2" reverses black and white, "3" blinks, "4" reverses underlined characters, "5" blinks underlined characters,
"6" is black and white inverted and blinking (repeated black character display → white character display → no display → black character display → ...),
“7” sets the underlined character as black and white inverted and blinking. The second line character attribute 52 and the third line character attribute 5
The character attributes 54 on the third and fourth lines are based on the character attributes 51 on the first line.

The display data 61 on the first line is displayed in the display area 141.
Indicates the character data to be displayed in the first line, and is a 160-byte S corresponding to 80 full-width or 160 half-width alphanumeric characters.
Recorded as JIS code / ASCII code. Although the number of characters that can be displayed on each line of the display area 141 at one time is limited, in consideration of the case where telop display is performed, the present embodiment is set so that up to 80 double-byte characters can be displayed. The second-row display data 62, the third-row display data 63, and the fourth-row display data 64 all conform to the first-row display data 61.

The key 21213 (# 1) is used by the read / write device 12 as a means for reading image data and / or character data, and is used for collation with the telephone 1. It is recorded as 8-byte binary data.

The bitmap data 71 is stored in the display area 14.
This is used when 1 is displayed as a bitmap.
The display area 141 is composed of 80 vertical dots × horizontal dots.
Since it is composed of 00 dots, it is displayed as 3000 bytes of binary data. However, the bitmap data 71 is “bitmap display” in the display mode code 43.
This is effective when a code is set, and "Text display"
Nothing is recorded.

The above is an example of the memory map according to the first embodiment of the present invention. In the present embodiment,
The case where four lines of messages are displayed in the display area has been described, but the same effect can be naturally obtained by allocating a necessary memory area even when displaying five lines of messages. In that case, the RFU (Reserved for
This can be easily realized by using an area of “Future Use”. In the present embodiment, there is no problem even if the text data storage area and the bitmap data storage area are distinguished.

Next, in order to explain the flow up to the display according to the first embodiment of the present invention, an IC as a module is described.
The case where the card 2 is used, the telephone 2 is used as a terminal, and the telephone 1 sequentially reads a plurality of image files of the IC card 2 and displays the image files in the display area 141 is used as an example. Here, the overall system configuration is the same as that of FIG.

FIG. 4 shows a flowchart of the control device 11 of the telephone. When the IC card 2 is not used, the flow is indicated by a dotted line in FIG. Three screens are recorded on the IC chip 21. In the text display mode, the display area 141 is divided into four parts in the horizontal direction, and characters are displayed on each line. Each line is composed of 16 characters. The characters on each line can be inverted, blinking, and telop displayed in addition to normal characters. Hereinafter, the change over time in the display area of the three screens will be described.

The control device 11 of the telephone recognizes, by reading the display mode code 43, that the IC card 2 arranged in the read / write device 12 is an IC card recording display data. At the time when the other party answers the telephone, the control device 11 accesses the file of the first screen among the files of the three screens recorded on the IC chip 21 and performs key matching, and then performs image data of the first screen. And / or read character data.

After displaying the display time data 41 for a predetermined time, the control device 11 accesses the data file of the second screen, performs key collation, and reads the data of the second screen. After displaying the display time data 41 for a predetermined time, the control device 11 accesses the third data file, performs key matching, and reads the data file on the third screen.

After displaying for a predetermined time by the display time data 41, the control device 11 recognizes that there is no other image to be displayed other than the three screens, and stores it in the image data and / or character data file of the first screen. After accessing and performing key matching, the image data and / or character data of the first screen is read. Thereafter, the controller 11 repeats a series of these operations until the line is disconnected. At the time of the line disconnection, the control device 11 deletes the image data being displayed from the storage device 13.

The above is an example in which the telephone 1 sequentially reads out a plurality of screen data recorded on the IC card 2 and displays the screen data on the control device 141 of the telephone according to the embodiment of the present invention.

Next, FIG. 5 shows a temporal change of the screen displayed in the display area 141. (A) in FIG. 5 is the first screen at time t1. The first and second lines indicate black-and-white inversion, and at time t1, white characters are displayed on both the first and second lines (the black-and-white inversion cycle is Δtr seconds). The third line is blank. The fourth line is a telop, and the first part of "Thank you very much, our company was listed on the First Section of the Tokyo Stock Exchange in May." The control device 11 controls the moving speed of the displayed characters so that the screen does not transition to another screen during the telop display.

FIG. 5B shows a screen at time t1 + Δtr. (C) in FIG. 5 is a screen at time t2 (t2> t1 + Δtr), and an image in dot display is displayed. (D) in FIG. 5 is a screen at time t3 (t3> t2). The first, third, and fourth lines are for normal display, and the second line is for white characters.

Although the above embodiment has been described with reference to display colors of white and black, the same effects can be naturally obtained with an electronic display device capable of displaying three or more colors.
In addition, although the character inversion cycle is set to Δtr, the cycle can be freely changed by setting a constant of the telephone 1.

As a second embodiment of the present invention, a plurality of screen data recorded on the IC card 2 are collectively read and recorded in the storage device 13 of the telephone 1, and the plurality of screens are stored in the display area 141. An example of split display will be described. FIG. 6 shows a flowchart for displaying a message according to this example. When the IC card is not used, the operation is indicated by a dotted line in FIG. The difference from FIG. 5 is that the image data and / or character data recorded on the IC card are read all at once before transitioning to the call state, and the data is resident in the storage medium of the telephone during the call. It is.
The change over time in the display area is the same as in FIG.

The basic system configuration applied to the second embodiment of the present invention is the same as that of FIG. IC card 2
Record message data for three screens. In text display, the display area 141 is divided into four parts in the horizontal direction, and characters are displayed on each line. Each line is composed of 16 characters. The characters on each line can be inverted, blinking, and telop displayed in addition to normal characters. Hereinafter, the change with time of the display area 141 for the three screens will be described.

The control device 11 of the telephone 1 recognizes that the IC card 2 arranged in the read / write device 12 is an IC card on which message data is recorded by reading the display mode code 43. At that time, the control device 11 collectively reads out the screen files 2121 (# 1 to # 3) for three screens from the IC chip 21 and records them in the recording device 13. At this time, header information indicating the first screen among the three screens, the second screen among the three screens, and the third screen among the three screens is added to the recording device 13.

The control device 11 accesses the first screen data file recorded on the storage medium 13 among the three screen files recorded on the storage medium 13 and performs key collation. The image data and / or character data is read and displayed in the display area 141. After displaying for a predetermined time by the display time data 41, the control device 11 accesses the data file of the second screen and reads the data of the second screen. After displaying for a predetermined time by the display time data 41, the control device 11 accesses the data file of the third screen and reads the data of the third screen. After displaying for a predetermined time by the display time data 41, the control device 11 recognizes that there is no other image to be displayed other than the third screen, accesses the data file of the first screen, and reads the data of the first screen. Read.

Thereafter, the control device repeats these series of operations until the line is disconnected. Control unit 11 at the time of line disconnection
Are the image data of the three screens and / or
Or delete character data.

In this way, the number of times the read / write device 12 accesses the IC card 2 during a call can be reduced, so that the load on the control device 11 can be reduced. In addition, it is possible to reduce the probability of collision with a state change signal or a billing signal due to insertion or removal of the IC card 2, thereby contributing to an improvement in communication quality.

As a third embodiment of the present invention, a module IC card 2 is used, two IC cards 2 on which screen data is recorded are inserted, and one IC card 2 is charged to another IC card 2. 9 shows an example of operation for displaying image data and / or character data when the character number changes.

The system configuration of the present embodiment shown in FIG. 7 is basically the same as that of FIG. 1, except that the reader / writer recognizes two IC cards at the same time. The recognition method is performed by, for example, anti-collision disclosed in JP-A-11-203427 and JP-A-11-203428. In each of the IC cards used, data for three screens is encoded.

After the call starts, the telephone sets the IC card 2 (#
The image files for three screens recorded in 1) are collectively recorded in the storage medium 13 of the telephone 1, and the three screens are displayed in a time-division manner in the display area 141 during a call. Billing target is I
In the case of moving to the C card 2 (# 2), the control device 11 deletes the image file recorded on the storage medium 13 and deletes the image file for three screens recorded on the IC card 2 (# 1). The three screens are collectively recorded in the storage medium 13 and the three screens are displayed in a time-division manner on the display area 141 during a call.

The above is an operation example in the case where a plurality of IC cards according to the present invention are used and the billing target is changed. According to the present invention, since the screen display target can be moved in a state where the frequency of the IC card 2 (# 1) is lost, the screen display in a time proportional to the frequency of use of the plurality of IC cards 2 can be performed. It becomes possible. In the present embodiment, the case where the image file is recorded every time the billing target changes is described. However, the capacity of the storage medium 13 is increased, and the recording is performed on the two IC cards 2 at the time when the call is started. Naturally, the same effect can be obtained by using a method of recording a plurality of screen files collectively.

As a fourth embodiment of the present invention, the key of the telephone 1 is updated according to the clock mounted on the control device 11 of the telephone 1, and the screen is compared with the key recorded on the IC card before the screen is updated. Here is an example of the display.

The system configuration is the same as in FIG. The IC card 2 stores image data and / or character data for three screens. Hereinafter, an operation example in which the key recorded in the storage medium 13 of the telephone 1 is changed according to the time and one of three screens of the IC card is not displayed will be described with reference to FIG.

FIGS. 8A and 8B are schematic diagrams of the storage area of the IC chip 2 and the recording device 13. FIG. The IC chip 21 has keys 21213 (#
1), key 21213 (# 2), key 21213 (#
3) is recorded. At time t = t1, keys 21213 (# 1) and 21213 are stored in storage medium 13 of telephone 1.
(# 2) and 21213 (# 3) are stored. The control device 11 checks the key 21213 of the IC card 2 and
The first screen, the second screen, and the third screen are displayed in a time-division manner.

At time t = t2, the control device 11
213 (# 2) is deleted. The control device 11 sets the time t =
After the elapse of t2, the key 21213 (# 2) of the IC card 2 is collated, but the display is skipped for the second screen because the key collation fails. At this time, the first screen and the third screen are alternately displayed in the display area 141 during a call.

At time t = t3, the storage medium 13 of the telephone 1
Are keys 21213 (# 1), 21213 (# 2), 2
1213 (# 3). Key 21213 (# 2)
Is downloaded from the remote device using the public network by time t = t3, and the key 21 is downloaded at time t3.
213 (# 2) is added. The control device 11 collates the keys of the IC card 2 and displays the first screen, the second screen, and the third screen in a time-division manner.

According to the present embodiment, the location, time, etc.
A screen display customized to the environment where the C card public telephone is installed can be provided. For example, three screen files are stored in IC
A case will be described in which the IC card 2 recorded on the chip 21 and recorded with the first screen for the national advertisement, the second screen for the East Japan area advertisement, and the third screen for the West Japan area advertisement is displayed during a call.

In a telephone set in western Japan, key matching fails when reading an advertisement for the eastern Japan region.
If you do not install the East Japan key on the phone,
Two types of screens can be displayed alternately, such as the first screen (for the whole country) → the third screen (for the West Japan) → the first screen (for the whole country) → the third screen (for the West Japan) →. Since the IC card 2 can be used in an IC card public telephone in the whole country, it is not possible to say that merely distributing or selling an IC card in which an advertisement content specialized in a specific area is distributed has a high appealing effect. By providing image data and / or character data recorded content of the IC card with versatility and determining whether or not to display a screen by key collation on the telephone side, a service with a high advertising effect can be provided.

The embodiments described above are described for facilitating the understanding of the present invention, and are not described for limiting the present invention. Therefore, the display method and the system disclosed in the above embodiments are intended to include all design changes and equivalents belonging to the technical scope of the present invention.
