DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message signal receiver such as a selective call receiver having a message display function.

[0002]

2. Description of the Related Art Conventionally, a selective call receiver includes a tone-only system, a number display system, a character display system, and the like. Among them, in particular, a message display system which receives a message signal transmitted from a transmitting side and displays a message, a selective call receiver of a character display system used as a so-called message signal receiver, has a long message signal. Often you want to send However, the display of the selective call receiver is usually not large enough to display such a long message signal at a time, and the length of the message signal that can be displayed at one time is limited.

In view of the above, all message signals have been conventionally displayed by scrolling the message signals which could not be displayed at one time by one digit or one line. FIG. 3 is a block diagram showing the configuration. In FIG. 3, 1 is an antenna, 2 is a receiving unit, 8 is a call notification circuit, 11 is a stop switch, 12 is a display switch, 13 is a control unit, 16 is a storage device, 17 is a storage means (RAM),
19 is a display device, 31 is an ID inquiry and function control means, 3
2 is a message length determining means, and 33 is a display control means.

Next, the operation of the conventional selective call receiver used as a so-called message signal receiver will be described with reference to FIG. First, a carrier modulated by a selective paging signal including an individual selective paging signal (ID code) and a subsequent message signal is received by the antenna 1 and demodulated by the receiving unit 2. The demodulated selective call signal is sent to the control unit 13. The individually selected call signal sent to the control unit 13 is compared with a call signal of the own device preset in the storage device 16 by the ID inquiry and function control means 31. If the two signals match, the ID inquiry and function control means 31 determines that the received selective calling signal is directed to itself, and drives the calling notification circuit 8 to, for example, generate a sound And notifies the user of it. This sound is generated when the user presses the stop switch 11 or
Alternatively, it stops after a certain period of time.

[0005] The control unit 3 stores the message signal received at the same time as the generation of the sound in the storage means (RAM) 17,
Message length determination means 32 built in control unit 13
, The number of digits of the received message signal and the display device 19
And the maximum number of display digits. If it is determined that the number of digits of the received message signal to be displayed is shorter than the maximum number of display digits of the display device 19, the entire text of the message is displayed on the display device 19 at once and the operation is stopped.

However, if it is determined that the number of digits of the received message signal to be displayed is longer than the maximum number of display digits of the display device 19, first, the first block of the message signal is displayed. Then, after a certain period of time, the message is sequentially scrolled from right to left by one digit or one line, and one digit or one line to be displayed there is read out from the storage means 17 and displayed in an empty display area. . This display operation is continued until the display of the entire message is completed. In addition, the moving amount and the moving speed of the scroll were fixed.

[0007]

However, in the above-described selective call receiver used as a conventional so-called message signal receiver, a message longer than the maximum display digit of the display device is scrolled and displayed. In such a case, the scrolling is performed for one digit or one line at regular intervals, and the moving speed is fixed. for that reason,
Changes in the message due to scrolling may be noticeable, and in order to correctly recognize the entire message,
The message before and after scrolling must be checked carefully, which is troublesome.

In addition, since the scroll speed is fixed, scrolling is too slow when a simple message or a small number of scroll digits is used, and when a difficult message or a large number of scroll digits are used. However, there is a problem that reading of a message displayed on the display device may be inconvenient, such as feeling that scrolling is too fast.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a method of smoothly scrolling a message display so as to improve the followability of reading a message, and a method of controlling a moving amount and a moving speed of a message at the time of scrolling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a message signal receiver according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG.
FIG. 1 is a block diagram showing a configuration of a selective call receiver which is a message signal receiver according to one embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an antenna for receiving a carrier modulated by a selective calling signal including an individual selective calling signal (ID code) and a message signal; 2, a receiving unit for demodulating the received carrier; and 3, a receiving unit for demodulating the received carrier. A control section for controlling a call notification circuit and a message display device, which will be described later, and processing the message signal when the selected call signal is collated and addressed to its own device; 21, message length determination means 22, and display control means 2
3 and so on.

The ID collation and function control means 21 includes an ID collation means for judging whether or not the received selective call signal includes a message signal addressed to the own device, and a message signal addressed to the own device. In this case, a call notification circuit 8 (to be described later) for notifying the user of the situation and a function control means for controlling a storage means (RAM) 7 (to be described later) for storing a message signal addressed to itself are provided. Of course, the ID collating means and the function control means may be separately provided separately.

The message length judging means 22 is processed by the control unit 3 and stored in the storage means (RAM) 7 with the number of digits (N1) of the message signal and the storage device (EEPR).
OM) 6 (to be described later) is compared with the maximum number of display digits (N2) of the message display device 9 (to be described later) stored in advance, and the magnitude relationship between N1 and N2 is determined to determine the result of the determination. It is sent to the display control means 23.

The display control means 23 executes control for displaying the message signal received and stored in the storage means (RAM) 7 on the display device 9 based on the judgment result from the message length judgment means 22.

Further, as another function of the selective call receiver according to this embodiment, 4 is a reverse switch for scrolling the message display on the display device 9 rightward, and 5 is a forward switch for scrolling the message display leftward. , 6 are storage devices for storing a call signal of the own device used for recognition of the own device, a scroll moving amount (dot unit) and a moving speed of a message display on the display device 9, and a maximum number of display digits of the display device 9. (EEPROM), 7 is storage means (RA) for storing the received message signal addressed to itself.
M) and 8 are call notification circuits for generating a sound or the like for notifying the user when the received selective call signal is determined to be directed to the own device.

Reference numeral 9 denotes a received message, and the number of digits that the message can display at one time (maximum number of display digits)
If it is longer, the display device can scroll the display of the message leftward or rightward in dot units.
In this embodiment, “dot unit” means that the scroll movement amount is determined on the basis of the number of dots (including a single dot and a plurality of dots). Dot group (for example, 1,
2, 3,..., N dot groups) in units of left or right.

Next, the operation of the selective call receiver, which is a message signal receiver according to the present embodiment, will be described with reference to FIG. In the reception waiting state, when the carrier modulated by the selective paging signal including the individual selective paging signal and the subsequent message signal is received by the antenna 1, it is demodulated by the receiving section 2. The demodulated signal is sent to the control unit 3, and the ID collation and function control unit 21 compares the individually selected calling signal included in the signal with the own calling signal from the storage device 6. If the two signals do not match, the message signal received at that time is ignored because it is determined that the message signal is not addressed to itself.

However, if the two signals match, the received message signal is determined to be addressed to itself, and is written to the storage means 7. At the same time, I
The D collation and function control means 21 drives the call notification circuit 8 to notify the user that the message signal has been received, for example, by generating a sound or the like. The sound or the like is stopped after a predetermined time, or stopped by pressing a stop switch (not shown).

Next, the message length determination means 22 compares the number of digits of the received message signal with the maximum number of display digits of the display device 9 stored in the storage device 6 in advance, and compares the comparison result with the display control means. 23. When the comparison result indicates that the maximum number of display digits of the display device 9 is longer than the number of digits of the message signal (N1 <N
2) The display control means 23 causes the display device 9 to display the received message signal as it is.

Conversely, if the comparison result indicates that the maximum display digit of the display device 9 is shorter than the number of digits of the message signal (N1> N2), the maximum display of the display device 9 is first performed. A message signal corresponding to the number of digits (N2) is displayed on the display device 9 (of course, the number of digits may be smaller). Then, when the forward switch 5 is pressed, the message display is sequentially scrolled leftward by the number of dots by the scroll movement amount stored in the storage device 6. The time interval between the scroll movements, that is, the scroll movement speed is also controlled by information stored in the storage device 6 in advance. This scrolling continues until all the rest of the message is displayed. Of course, the stop may be performed halfway by using a stop switch (not shown) or the like.

When the forward (left) scroll is completed (or scrolling may be performed), when the reverse switch 4 is pressed, the message is scrolled from left to right.
The first message for the maximum number of display digits of the display device 9 is displayed again. This is useful when you want to reread the previous message. When the number of messages is larger than two lines (two times the maximum number of display digits) of the display device 9, the message may be scrolled continuously until all the remaining messages are displayed. To stop and press the forward switch 5 to scroll the next line.

The display of the message on the display device 9 can be turned off by pressing a stop switch (not shown), but it may be turned off automatically after a fixed time from the last scroll. Thereafter, the selective call receiver returns to a state of waiting for a carrier wave. Also, a suitable switch, for example,
By pressing the forward switch 5 or the like, the storage means 7
, The previously received message signal is read out, displayed in the same manner as described above, and a scroll operation can be executed.

Next, the message display operation according to the present invention will be described in detail with reference to FIG. FIG. 2 is a diagram showing a scroll display operation when the display device 9 displays the first three characters of the received message and the subsequent scroll state. The display device 9 according to this example uses a dot display method of 48 × 16 dots (maximum display digits 3 characters × 1 line), the scroll movement amount is in units of 8 dots (that is, in units of half characters), and the movement speed is 0.5 seconds. Assume scrolling every time.

Also, in this example, assuming that the message to be received and displayed by the selective call receiver is five characters "I want a phone call", the display device 9 first displays the first three characters "I want a phone call." Is displayed ((A) in FIG. 2). Then, when the forward switch 5 is pressed, the message display scrolls to the left in units of 8 dots as shown in (b) of FIG. 2, and the left half of the character "den" disappears from the left end of the display device 9, The left half of the character “shi” appears from the right end of the display device 9.

Thereafter, when 0.5 seconds have elapsed, the message display is further automatically scrolled to the left by 8 dots, and the display of "I want to talk" appears ((c) in FIG. 2). Then, the message display is automatically scrolled leftward by 8 dots, and the right half of the character "talk", the "desired", and the left half of "i" appear ((d) in FIG. 2). After another 1.5 seconds have elapsed, the message display automatically scrolls leftward by 8 dots, the character "want" is displayed on the display device 9 ((e) in FIG. 2), and the scroll operation ends. I do.

For example, when the reverse direction switch 4 is pressed, the message display "want" scrolls rightward in the opposite direction to that described above by 8 dots at 0.5 second intervals as described above. Scrolling ends with the display of “calling desire”. In this example, the characters are scrolled to the half, so that the scroll is considerably coarse. However, since the characters are half displayed on the display, it is understood that the message can be easily recognized.

The scroll movement amount and movement speed of the message display according to the present embodiment are determined based on the storage information previously written in the storage device 6 as described above.
That is, the amount of movement is determined based on the minimum unit of the scroll movement direction constituting the character. For example, when the display device to be used is a dot matrix type display device generally used for a selective call receiver, one dot is the minimum unit. Therefore, when one character is composed of 16 × 16 dots, the scrolling movement amount of the message is scrolled by half a character when set in units of 8 dots as in the present embodiment, and is scrolled by one character when set in units of 16 dots. If it is set in units of 80 dots, it will be scrolled every five characters. That is, it can be understood that the “dot unit” is a dot group unit including one dot.

The moving speed of the scroll refers to the time interval between the scrolls. In the present embodiment, the moving speed is set to 0.5 seconds, but the scroll speed is set to give the optimum visibility to each user. be able to. In general, when the scroll movement amount is large, the movement speed is slow, and conversely, for example, when the scroll movement amount is as small as one dot, it is necessary to set the considerably high speed to feel slow, and a comfortable scroll display cannot be obtained. Will.

Needless to say, the scroll movement amount (the number of dots per scroll) and the movement speed according to the present invention are not limited to the above-described embodiment, and the scroll movement amount may be, for example, from one dot to the entire width of the display device. Can be arbitrarily set to the number of dots or more, and an arbitrary time can be set so that the movement speed also matches the set scroll movement amount. In the present embodiment, these settings can be changed easily by rewriting the storage device (EEPROM) 6. Further, any method may be used as the changing means, but the storage device (EE
When a PROM is used, it can be easily rewritten by a ROM writer.

In the present embodiment, the scroll moving amount and the moving speed are set using a storage device (EEPROM), but any other storage means such as a RAM can be used. Further, the scroll moving amount and the moving speed are set by the user of the selective calling receiver, but the information on the scroll moving amount and the moving speed is set on the transmitting side and is included in the selective calling signal transmitted. You may. In this case, the storage device of the selective call receiver to be received may be a simple one such as a register, and does not need to be set in advance.

[0033]

The message signal receiver such as the selective call receiver according to the present invention is constructed as described above.
With a simple configuration, the scroll movement amount can be set in dot units, and the scroll movement amount and movement speed can be set widely and arbitrarily according to the user and display contents, so that the message can be read. In this case, the message display changes smoothly, and good follow-up performance can be obtained, and optimal scroll display visibility can be obtained. Further, the message signal receiver according to the present invention can scroll the message display in the reverse direction (right direction), which is convenient when it is desired to reread an arbitrary part of the message. In particular, by setting and transmitting the information on the scroll movement amount and the movement speed on the transmission side, there is an effect that the display content and the scroll condition of the message signal receiver at a remote place can be controlled.
