DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable receiving terminal according to the present invention comprises a receiving section for receiving a call signal and data transmitted by radio, and detecting a call signal received by the receiving section to generate sound or vibration. An incoming notification unit that notifies an incoming call, a data reading unit that reads data stored in an external storage medium, a storage unit that stores data read by the data reading unit and data received by the receiving unit, A Braille conversion unit that converts the data stored in the storage unit into Braille information, and a Braille display unit that displays the converted Braille information in Braille, wherein the Braille display unit is received and stored by the receiving unit. The data stored in the storage unit and the data read by the data reading unit and stored in the storage unit can be switched and displayed by a display switching key provided in the main body of the receiving terminal.

It is preferable that the Braille display unit has a size that occupies most of the surface of the receiving terminal main body, and can be scroll-displayed in page units by a page feed key provided on the receiving terminal main body.

The data reading unit is a floppy disk or IC
An external storage medium such as a card or a CD-ROM is structured to be removably inserted into the main body of the receiving terminal.

Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a portable receiving terminal 1 according to the present invention includes a receiving section 2 for receiving a call signal and data transmitted wirelessly, and a data reading apparatus for reading data stored in an external storage medium. Unit 3, a control unit 4 for controlling the whole, an incoming call notifying unit 5 for detecting a call signal received by the receiving unit 2 and notifying an incoming call by sound or vibration or both, and read by the data reading unit 3. A storage unit 6 for storing the received data and the data received by the reception unit 2;
And a Braille conversion unit 7 for converting the data stored in the storage unit into Braille information under the control of the control unit 4, and a Braille display unit 8 for displaying the converted Braille information in Braille.

As shown in FIG. 2, the Braille display section 8 is formed to have a size occupying most of the surface of the receiving terminal body 9.
For example, as shown in FIG.
A large number of blocks are arranged in a matrix as one block 11 with 0 as a unit. FIG. 5 shows an example of correspondence between the appearance and appearance of pins, characters, ASCII codes, and reception codes.

A power key 12 for turning on / off the power and a display switching key 1 for switching data to be displayed on the Braille display unit 8 are provided on the remaining portion of the surface of the receiving terminal body 9.
3. A next page key 14 and a previous page key 15 for scrolling the display of the braille display section 8 in page units are provided. The braille display unit 8 has a storage unit 6
And the data read by the data reading unit 3 and stored in the storage unit 6 are switched and displayed each time the display switching key 13 is pressed.

As shown in FIG. 3, the data reading section 3 transmits an external storage medium such as a floppy disk, an IC card, a CD-ROM, or the like through a medium entrance 16 provided on the side surface of the receiving terminal body 9. And can be detached by pressing the eject button 17.

Next, the operation will be described with reference to FIGS. FIG. 6 shows a main routine. When the power is turned on by pressing the power key 12 in step S1, the receiving unit 2
If the data is received by the data reading unit 3, the receiving processing routine shown in FIG. 7 is entered in step S2. If the data is read by the data reading unit 3, the reading processing routine shown in FIG. 8 is entered in step S3. The routine enters a data display processing routine shown in FIG.

If the receiving unit 2 has received a message, it enters an interrupting reception processing routine shown in FIG. 7 and determines in step S21 whether a message has been received.
At 22, the incoming call is notified by the incoming call notifying unit 5 by sound and / or vibration, and then the process proceeds to step S 23 to store the received data in the storage unit 6.

By reading from the data reading section 3, FIG.
Is entered, it is determined in step S31 whether or not there is read data, and if so, the read data is stored in the storage unit 6.

In the data display routine of FIG. 9, the key input state of the display switching key 13, the next page key 14 and the previous page key 15 is determined in step S41, and the reception data side is selected by the display switching key 13. At this time, the received data received by the receiving unit 2 and stored in the storage unit 6 is read out in step S42. When the read data side is selected, the data is read out by the data reading unit 3 and stored in the storage unit 6. Read the read data. Storage unit 6
Is read from the control unit 4 in step S45.
Is converted into Braille information by the Braille conversion unit 7 in accordance with the control described above, and is output to the Braille display unit 8 in step S46, and is displayed as Braille by the appearance of the pin 10.

Although the amount of information that can be displayed on the braille display unit 8 is limited, if one display is one page, when the next page key 14 is pressed, the next page stored in the storage unit 6 is displayed. The page portion is read out in step S42 and output to the braille display unit 8, and when the previous page key 15 is pressed, the previous page portion stored in the storage unit 6 is stored in step S42.
It is read out at 42 and output to the braille display unit 8.

The received data is the next page key 1
It is also possible to display without scrolling with 4 or the previous page key 15. The storage unit 6 can be cleared by turning off the power. Also, a power key 12 and a display switching key 1
3. On the surface of the next page key 14 and the previous page key 15,
Braille for identification can also be provided.

[0020]

As described above, according to the present invention, not only can radio reception information be displayed as Braille, but also information stored in an external storage medium can be read and immediately displayed as Braille. Two types of information can be selected with the display switching key and displayed at any time.

By making the braille display part occupy most of the surface of the main body of the receiving terminal and by enabling scroll display in page units, it is possible to reduce misreading of braille even if the data amount is large.
