DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a radio selective call receiver, and particularly relates to an improvement in the display function of a radio selective call receiver with a display function.

[Conventional technology]

As a wireless selective call receiver with a display function (hereinafter referred to as a receiver), there is a device equipped with a clip 73 as shown in FIG. This receiver can be carried using a clip on your waist belt.

At the time of reception, all the information displayed on the display section 72 can be checked while the user is wearing it. In addition, when it is attached to the chest pocket of a jacket, put the receiver main body 71 in the pocket and
Take it outside and use it like inserting a pen into your pocket. For this reason, if you check the displayed information while wearing it in your second breast pocket, the direction in which the first displayed information is displayed changes, making it difficult to see.

[Problem that the invention seeks to solve]

When the conventional receiver described above is used by being attached to clothing such as in a breast pocket or a waist belt, the method of carrying the receiver changes depending on the season, the physique, gender, etc. of the person carrying the receiver. At this time, if you try to check the message while carrying it, the display orientation may become difficult to read depending on how you carry it. In particular, when receiving display information using numbers as information, serious misunderstandings may occur because they have no meaning like words or sentences.

[Means for solving problems]

The present invention provides a wireless selective calling receiver with a display function capable of receiving a radio frequency signal modulated by at least a wireless selective calling signal and a display information signal, which displays visible display information corresponding to the display information signal. A control means connected to the display means for changing the display direction of information displayed on the display means, and an operation means connected to the control means. .

[For production]

With this configuration, there are two receivers according to the present invention.

By changing the display direction using the operating means depending on how the receiver is carried, the receiver can be accurately checked whether the receiver is carried on the chest or waist. Note that switching the display direction referred to herein includes not only turning all of the two display information upside down, but also changing the entire arrangement of the one display information. That is, in the case of FIG. 7, the display information viewed from the clip 73 side is switched so that the display information viewed from the opposite side becomes the same.

〔Example〕

Next, two aspects of the present invention will be explained with reference to the entire mouth.

FIG. 1 shows an embodiment of the present invention, in which numeral 1 represents an antenna.

2 is a radio section, 3 is a waveform shaping section, 4 is a decoder, and 5 is a programmable I in which a self-selected call number is written.
J He Only Memory (below).

(referred to as FROM), 6 is a message data processing unit, 7 is a buffer, 8 is a speaker, 9 is a display control unit, 10 is an LC
D, 11 is a crystal oscillation unit for generating a timing clock for the decoder 4. Sound stop switch So
stops the speaker 8 that is producing sound. The LCD display reset switch (hereinafter referred to as reset switch) S+ is used to display the message partially in sequence when the message is longer than the number of digits on the LCD. The display direction changeover switch (hereinafter referred to as changeover switch) 82 is L.
This is for switching the display direction of the CD 10.

Next, the operation of the receiver will be explained with reference to FIG. A desired radio signal received by the antenna 1 is received and demodulated by the radio section 2, and a dinotal signal a shown in FIG. 2 is obtained by the waveform shaping section 3.

When this distal signal a is input, the decoder 4 synchronizes bits with the repeating "1", 0" turn P shown in FIG. 2, and shifts to detecting the first subsequent frame synchronization signal SC.

When the frame synchronization signal SC is detected, the decoder section 4 reads data from the FROM 5 in which its own selective call number is written, using that as a starting point.

All checks are made to see if they match address signal A in disortal signal a. When it is confirmed that they match, the decoder section 4 activates the message data processing section 6 from the signal line b (FIG. 1) to receive and decode the subsequent message signal M, and also sends a 1-stop signal. E's standby state becomes the state.

When the stop signal E indicating the end of the message signal M is detected in this way, as mentioned above, the own selective calling number and address A are The ringtone 8 is made to sound via the bar 7 to notify the person carrying the receiver that he or she has been called.At this time, the ringing can be stopped using the sound stop switch So.

On the other hand, the message data processed by the message data processing section 6 is displayed as a message on the LCD 10 by the two-way display control section 9. At this time, reset switch S!
By turning on the long message i LCD 1
It can be displayed sequentially in units of 0 display digits. Then, when the last messeno is fully displayed, if the reset switch St'r is turned on again, the display disappears. When the changeover switch S2i is turned on while a message is being displayed, the display direction of the LCD 10 can be changed.

Regarding the message data processing section 6 with reference to FIG.
I will explain in more detail. 101.102 is an entry capo),
103 is a serial interface.

104 and 105Vi output ports, 110 is a data bus. 120 is a program counter, and 130H is a program memory in which a sequence of instructions to be executed is stored and from which the contents of the address specified by the program counter 120 are read. 140 is an ALU (arithmetic and l) that performs various operations such as arithmetic operations and logical operations.
150 is an instruction decoder that decodes information from the program memory 130 and supplies control signals corresponding to the instructions to each section. Reference numeral 160 is an achievable emulator used for transmitting and receiving data between the ports 101 to 105, 170 is a RAM for storing various data, and 180 is a system clock generator that determines the execution command cycle time.

Next, the display control section 9 will be explained with reference to FIG. 290 is a serial interface.

280H command/data register, 27011 command decoder, 260 data pointer, 240 first segment decoder, 250 second segment decoder,
230 is a data memory, 220 is an LCD data latch,
210 is an LCD driver.

The transfer of data between the message data processing section 6 and the display control section 9 will be explained. First, the message data processing unit 6 sets the signal line cs to the 10-level.

Due to this, the second display control section 9 enters the data input mode. Also, by setting it to high level after data input, data display mode is entered. Next, commands and data are sequentially transferred from the signal line 5OUT. The timing of the transfer is determined by the signal line W. At this time, in order for the display control unit 9 to recognize whether the signal is a command or data, the message data processing unit 6 sets the signal line C/15 to high level for a command and low level for data.

The serial interface 290 receives serial signals from the message data processing section 6.

Output to command/data register 280. When a command is input to the command/data register 280,
The contents are transferred to the command decoder 270. Command decoder 270 decodes the command, and depending on its contents, command/data register 280 . First segment decoder 240°, second segment decoder 250. Controls data point/removal 260. When data is input to the command/data register 280, command decoder 1'
The data is output to either the first segment decoder 240 or the second seventh segment decoder 250 indicated by 270. When the first segment decoder 240 and the second segment decoder 250 receive data, it is
Convert to a display code for display. The display directions of the first segment decoder 240 and the second segment decoder 250 differ by 1800 degrees when two images are displayed. That is, it is converted into a display code that displays display information that is completely reversed vertically. Therefore, by specifying either of these two segment decoders with a command, the display direction of one display information can be changed. The display code output from the first segment decoder 240 or the second segment decoder 250 is held in the data memory 230,
Furthermore, it is output to the LCD driver 210 via the LCD data latch 220. The LCD driver 210 displays the entire message on the LCD 10 according to the display code from the data memory 230.

Next, the switching of the display direction of the displayed message when displaying the message, in other words, the operation of the vertical inversion function will be explained using the flowchart of FIG. 5 and FIGS. 3 and 4.

In step 1, the receiver has already received the message, and the RAM j, 70 of the message data processing section 6 is
It is assumed that Menose~no is inputted above and the data is transferred to the 1 display control section 9.

In step 2, the message data processing unit 6 determines whether the operation switch s2 is on or off from the input port 102. When it is off, a command SD 1 i that specifies the first segment decoder 240 is generated.

When it is on, the second segment decoder 250 'i' is specified? '5D2i is generated and output to the serial interface 103.

In step 3, the command and message data i LCD I O on the RAM 170 are sent to the display control section 9 in the number of data that can be displayed at once. In the message data, one character corresponds to an address on the RAM 170, and the data is stored on the RAM 170 in the order of the character string of the message, starting from the lowest address.

When the command SDI is issued, message data is sent in the order of addresses on the RAM 170 from the smallest to the smallest.

However, when the command SD 2 i occurs, it is sent in the reverse order.

In this operation, if the display is only flipped vertically using two segment decoders, the display direction of the message will only change by one character position.

This is an operation to prevent character strings from being displayed in reverse order when multiple digits are displayed on the LCD 10.

In step 4, the 2 display control section 9 transfers the command and data transferred from the message data processing section 6 to the signal line C/1.
5, the command is determined by the command decoder 270
Then, the data is output to the segment decoder 240 or H segment decoder 250 instructed by the command decoder 270. The command decoder 270 transfers data to the first segment decoder 240 when the input command is sDl.
and output the data to the second segment decoder 250 at SD20.
Give instructions to 80.

In step 5, the data converted into a display code by the segment decoder is stored in the data memory 230.

In Stella f6, display data is output to the LCD driver 210 via the LCD data latch 220i.

displayed on the LCD 10.

The message data processing unit 6 determines from the input port 102 whether the changeover switch S2 has been switched in the Stella f7. If it cannot be switched, LCD data launch 2
The display data latched by 20 is sequentially output to the LCD driver 210 and displayed on the LCD 10. (Return to step 6) Therefore, the 9 display state remains unchanged.

When the changeover switch S2 is switched, the message data processing unit 6 returns to step 2 and transfers the message data on the RAM 170 displayed on the LCD 10 in step 6 to the display control unit 9 again.

In step 7, since the selector switch S2 has been switched, the previous LCD display information.

In order to display a display in which the display direction has been switched by 180°,
If the command that occurred during the previous LCD display is SDI, then SD
2'i and SD2, SD 1 i is generated.

Figure 6 shows LCD 1 when the selector switch S2 is switched.
This is an example of displaying 0. For example, if the display is as shown in Figure 6 (a) when the receiver is carried on the waist with the waist belt fully utilized, when the receiver is carried in the breast pocket, the switch Sz is fully turned on. 1 display direction in Figure 6 (b
) and rotate it 180°.

〔Effect of the invention〕

As explained above, according to the present invention, an easy-to-read display can be provided whether the receiver is carried on a waist belt or in a chest pocket, thereby eliminating misidentification of information.
