2. Description of the Related Art Radio selective calling receivers (pagers)
Is widely used as a portable receiver of a paging system for calling an individual by using a public line, and recently, a service for transmitting a message by adding a message signal to a selective call signal is also performed.

First, a conventional radio selective calling receiver will be described with reference to FIG. FIG. 4 is a configuration block diagram of a conventional radio selective calling receiver. As shown in FIG. 4, the conventional radio selective call receiver has an antenna 1 for receiving a signal.
A radio unit 2 that amplifies and demodulates the received signal, a waveform shaping unit 3 that shapes the waveform of the received signal, a decoder 4 that compares the ringing signal in the received signal with its own ID, and a speaker 8 For amplifying the signal, a speaker 8 for outputting a ringing tone, and a CPU 9'for processing and controlling
An LCD 12 as a display unit, an LCD driver 11 for driving the LCD 12, and a switch unit 13.

Further, the decoder 4 has a crystal oscillator 5 which oscillates a reference clock and a PR which stores its own calling number.
A RAM 10 for storing message data is provided in the CPU 9 ', which is connected to the OM 6.

The basic operation of the radio selective calling receiver having the above configuration will be briefly described with reference to FIG. The signal received by the antenna 1 is amplified and demodulated by the radio section 2 and sent to the decoder 4. The decoder 4 synchronizes with the received signal based on the clock of the crystal unit 5, and
The own ID in the OM 6 is compared with the calling signal in the received signal. If they match, the decoder 4
Outputs a sound signal to the amplifier 7 via the CPU 9 ',
A ringing tone is output from the speaker 8 and the CPU 9 '
The message signal following the ringing signal is sent to.

Then, the CPU 9'decodes the message signal received from the decoder 4, and when the end of the message signal is judged, the decoded message data is stored in the RAM 10 '.
To memorize. Then, LC via the LCD driver 11
Drive D12 and display the message. The basic operation of the radio selective call receiver is performed in this way.

Next, the RAM 10 will be described with reference to FIG. FIG. 5 is a schematic explanatory view showing a storage area of the RAM 10. As shown in FIG. 5, the RAM 10 includes a file information storage unit (F1 to F8) 10a and a sector unit (S1 to S8).
S10) 10b. Sector part 10b
Is a part that actually stores the message data, and the file information storage part 10a is a part that stores the number (start address) of the sector part in which a series of message data is stored as file information.

In the example shown in FIG. 5, the file information storage unit F1 indicates that a series of message information has been written in the sector S1 and the sector S2.
If the message data is read in the order of 3, a series of message information can be obtained.

That is, when a message display instruction is input, the CPU 9'reads file information (sector section number) from the file information storage section 10a, reads message data from the designated sector section 10b,
The output is output to the LCD driver 11 and displayed on the LCD 12.

Further, in the conventional radio selective call receiver, when the message is too long to be displayed on one screen, scroll display is performed. Here, a scroll display method based on the conventional message display processing method will be described with reference to FIG. FIG. 6 is an explanatory diagram showing a conventional scroll display method.

In FIG. 6, the case of displaying the message (F1) will be described. In the conventional scroll display method, the CPU 9'first reads a series of message data from the sector section 10b designated by F1 of the file information storage section 10a, and displays it as display data in a display data area (not shown) in the RAM 10. ). The display data area has a sufficient capacity to store the display data of a series of messages that can be received by one reception. Then, as shown in FIG. 6, assuming that the maximum message length (maximum display length) that can be displayed at one time is 1, the CPU
9'is the maximum display length l in order from the beginning of the display data area.
The data corresponding to is read, output to the LCD driver 11, and displayed on the LCD 12 (display 1).

When the scroll switch of the switch unit 13 is depressed, the CPU 9'starts from the portion of the display data area corresponding to the continuation of the initially displayed data.
As the data for the next display, only the length corresponding to the maximum display length 1 is read and displayed (display 2).

Similarly, when the scroll switch is depressed, the CPU 9'reads the continuation of the display data by the amount corresponding to the maximum display length l and sequentially displays them (displays 3 and 4). The last part of the display data may be less than the maximum display length l (display 5). In the case of the display data F1 shown in FIG. 5, the entire message is displayed by scrolling four times.

[0014]

However, in the above-described conventional radio selective call receiver and message display processing method, the user is required to perform scroll display each time.
There is a problem in that the switch operation is complicated because the scroll switch has to be pressed to sequentially switch the display.

The present invention has been made in view of the above circumstances, and it is possible to automatically perform scroll display without pressing a scroll switch, and to reduce switch operation and improve convenience. It is an object of the present invention to provide a radio selective call receiver and a message display processing method capable of performing the above.

U presets a specific address interval in the display data area in RAM, and sequentially moves the read start position by the set address interval according to the timing from the clock to read and display the message data. Thus, the scroll display can be automatically performed without pressing the scroll switch.

The basic configuration of the radio selective calling receiver of this embodiment is almost the same as that of the conventional radio selective calling receiver shown in FIG. 4, and the antenna 1, the radio section 2, and the waveform shaping section are provided. 3, a decoder 4, a crystal oscillator 5, and a PROM 6
, Amplifier 7, speaker 8, CPU 9, and LCD 1
2, an LCD driver 11, and a switch unit 13. Of the above-mentioned components, the configuration is the same as the conventional one except the CPU 9, and the operation is also the same as the conventional one.

Here, C, which is a characteristic part of this embodiment,
The PU 9 will be described with reference to FIG. FIG. 1 is a functional block diagram of the CPU 9 and its peripherals of the radio selective calling receiver according to the embodiment of the present invention. As shown in FIG. 1, the CPU 9 of the radio selective call receiver according to the present embodiment is provided with a clock generating means 21, a display data reading means 22, an address interval setting means 23, and a RAM 10. Further, the RAM 10 is provided with a file information storage unit 10a similar to the conventional one, a sector unit 10b and a display data area 10c, and an address interval setting area 10d which is a characteristic part of the present embodiment.

Next, each component will be specifically described with reference to FIG. The file information storage unit 10a, the sector unit 10b, and the display data area 10c have the same configuration as the conventional one. The sector unit 10b stores the message data sent from the decoder 4, and the file information storage unit 10a. Stores the number of the stored sector section 10b as file information for each series of message data, and the display data area 10c displays the message at the time of displaying the message.
The CPU 9 stores the display message data (display data) read from the sector section 10b. Then, the display data reading means 22 reads the display data from the display data area 10c, and the LCD driver 11
It is designed to output to and display.

The clock generating means 21 generates a clock and outputs it to the display data reading means 22, and the display data reading means 22 follows the timing given from the clock generating means 21 to display data area 10c. The display data corresponding to one display, that is, the maximum display length l is read and output to the LCD driver 11.

At this time, as a feature of the present embodiment, the display data reading means 22 reads the set address interval (set address interval) from the address interval setting area 10d of the RAM 10 and displays the display data area 1
The read start position from 0c is sequentially moved by the set address interval at each read timing to read the display data and output it to the LCD driver 11. The specific operation of the display data reading means 22 will be described later in detail.

The address interval setting means 23 sets an address interval in the address interval setting area 10d in the RAM 10 in accordance with the input from the switch section 13. The address interval setting area 10d is an address interval setting means. The address interval (set address interval) set by 23 is stored.

The set address interval defines the address interval of the read start position when the display data reading means 22 reads the display data from the display data area 10c. For example, the set address interval is a and the display data area is When the previous read start address in 10c is k, the read start address at the next timing is k + a.

As a result, the display data reading means 22
When the display data is read from the display data area 10c, the moving amount of the start address to start reading is defined, and the scrolling speed (scrolling pattern)
Is determined. That is, when the address interval set in the address interval setting area 10d is large,
The width of movement in one scroll increases, and the scroll speed increases. On the contrary, when the address interval is small, the scrolling speed becomes slow because the movement width in one scroll is small.

Here, the operation of the display data reading means 22 of the present embodiment will be specifically described with reference to FIG. FIG. 2 shows the display data reading means 2 of the present embodiment.
It is a schematic explanatory drawing which shows the display data reading method of 2.
As shown in FIG. 2, assuming that the set address interval set in the address interval setting area 10d is a, the first read start address (initial address) is A0, and the maximum display length is 1, the display data reading means 22 When receiving the display instruction, first, the set address interval is read from the address interval setting area 10d and stored, and the initial address A0 is set to the pointer (not shown) indicating the read start position.

Then, the display data reading means 22 is
In the first display, data corresponding to the maximum display length 1 is read from A0 of the display data area 10c, output to the LCD driver 11, and displayed on the LCD 12. Then, an address obtained by adding the set address interval a to A0 is obtained and set to the pointer. This is the read start position A1 (A1 = A0 + a) for the next time (after scrolling once).

Then, when the next read timing is given from the clock generation means 21, the display data reading means 22 causes the address indicated by the pointer value, that is, A1.
At the read start position, data corresponding to the maximum display length l is read from A1 and output to the LCD driver 11. As a result, scroll display is performed once. Then, the next read start position A2 (A2 = A
1 + a) is calculated and set to the pointer.

In the same manner, the display data reading means 22 reads the display data using the address of the pointer value as the read start address in accordance with the clock timing, calculates the next read start address, and sets the pointer value. repeat. Thus, the message display processing method of the radio selective calling receiver according to the present embodiment is performed, and the scroll display is automatically performed even if the user does not press the scroll switch. .

That is, the scroll speed of scroll display (display pattern of scroll display) in the present embodiment is determined by the set address interval set in the address interval setting area 10d. It is possible to change the speed. Therefore, the user can obtain a desired display pattern by setting an arbitrary address interval from the switch unit 13.

Next, scroll display in the radio selective call receiver of this embodiment will be described with reference to FIG. FIG. 3 is a schematic explanatory view showing a display pattern of scroll display in the radio selective calling receiver of the present embodiment. In FIG. 3, two display patterns (pattern 1 and pattern 2) will be described as an example. The setting address interval is
In pattern 1, m is set, and in pattern 2, n (m> n),
The maximum display length is 1. The display 1, the display 2, ... Show the display data that is read at each display timing in the pattern 1, and the display data that is read at each timing in the display 1 ′, the display 2 ′ ,.

As shown in FIG. 3, when reading the display data of the message indicated by F1, in the pattern 1, the display data reading means 22 displays the initial address A0 in the display 1.
The data corresponding to the maximum display length l is read from
Then, the read start position is shifted by m and A1 (A1 =
A0 + m) and read the data corresponding to A1 to l. In the same manner, the reading start position is moved by m at each timing to be A2, A3, ... And the display data is sequentially read and displayed.

In the pattern 2, the display data reading means 22 reads the display data corresponding to the maximum display length 1 from the initial address B0 in the display 1 ', and in the display 2', the read start position is shifted by n. B1 (B1 = B
0 + n) to read the data. Similarly, the reading start position is sequentially moved by n at each timing, and B2,
Display 3 ', display 4', ... are displayed as B3 ....

Here, assuming that the display data reading means 22 reads the display data at the same timing in the pattern 1 and the pattern 2, as shown in FIG. 3, in the pattern 1 in which the movement amount of the read start position for each timing is large. In this case, the movement amount of the display portion at each timing becomes larger and the scroll speed becomes faster than the pattern 2 having a small movement amount.

According to the radio selective calling receiver of this embodiment and the message display processing method in the radio selective calling receiver, the CPU 9
The RAM 10 has an address interval setting area 10d for storing a specific address interval, and the display data reading means 2
2 reads the display data from the display data area 10c according to the timing from the clock generating means 21 and outputs L
When outputting to the CD driver 11, the read start position for each timing is moved by the set address interval set in the address interval setting area 10d to read the display data. Even if the button is not pressed, scroll display can be automatically performed, and the switch operation can be reduced, thereby improving the convenience.

Further, since the address interval set in the address interval setting area 10d is set by the user by inputting it from the switch section 13, there is an effect that a desired scroll speed can be obtained.

[0038]

According to the first and second aspects of the present invention, scroll display can be performed by sequentially repeating the operation of reading the data of the received message in the display data area and outputting it to the display unit in accordance with the address interval set from the outside. It is possible to increase the scrolling speed by increasing the address interval and decrease the scrolling speed by decreasing the address interval. The received message can be scroll-displayed at an arbitrarily set address interval from the outside, that is, at an arbitrary scroll speed.
