DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving apparatus for displaying data received from an external device.

[0002]

2. Description of the Related Art Some word processors, personal computers, electronic organizers, and the like have a data transmission / reception function and can store and display data transmitted from another device via a communication cable.

[0003] Some pagers and other wireless devices receive kanji mixed data and display the data. These devices have a font memory, such as a ROM, that stores the display fonts of kanji that correspond to the character code, and read the display font that corresponds to the received character code from the font memory and display it. I have.

In the case of small devices such as an electronic organizer and an electronic timepiece having a data storage function, to reduce costs,
Alternatively, since the storage capacity of the ROM cannot be increased so much to reduce the size or the like, display fonts such as kanji that are not frequently used may not be stored in the font memory. Therefore, conventionally, when the display font corresponding to the character code received from the external device does not exist in the font memory on the receiving side, all dots at the position where the corresponding character is to be displayed are turned on or blinked, or the portion of the frame is displayed. Illuminated the dot, etc., to indicate that there was no corresponding display font.

On the other hand, the above-mentioned word processors, personal computers, and the like have a so-called external character function that allows a user to create an arbitrary display font and register the created display font. Therefore, it is conceivable that a user creates a display font of a kanji that cannot be displayed using this external character function, and replaces the corresponding kanji in the received data with the created display font.

However, in order to display or store characters registered as external characters in data or data, it is necessary to designate a character to be displayed or stored each time. Therefore, even if the display font of the kanji that does not exist on the receiving side is registered as an external character, the next time you want to display the same kanji,
It was necessary to specify the registered external character in the same manner, and the specification operation was extremely troublesome.

[0007]

An object of the present invention is an object of the invention, the character of Chinese characters, such as the display font is not stored in the receiving side of the device, just an easy-to-view using the display font to create the user
Another object of the present invention is to provide a receiving device that can easily create a font .

[0008]

The gist of the present invention is that a display font created by a user is stored in a memory together with code data.
When code data is received from the outside, a display font having code data that matches the received code data is stored in advance or, if already created by the user, is read out from the memory and displayed and stored.
If not, specify the location and use the key to
Code that has no display font when switched to mode
Stores data in memory and creates display fonts
Code data and the created display font
Are stored as a set in a memory.

PU) 43.

The key input unit 44 includes the above-described SA to SD keys, S1 to S4 keys, and the like, and outputs an operation signal of each key to the control unit 43. The control unit 43 controls the operation of the entire circuit, executes a later-described reception process, transmission process, key process, and the like according to a program stored in the ROM 45, and stores the processing result in the RAM 46, The display font of the kanji corresponding to the character code specified in the reception processing or the key processing or the like is read from the font memory 47 such as a ROM, and the read display font is output to the display control unit 49. Further, the control unit 43 exchanges data with an external device via the communication circuit 48.

The display control unit 49 is composed of a display buffer and a display driver, temporarily stores display data such as characters and symbols output from the control unit 43, and displays those data on a display unit (liquid crystal display). 13 is displayed.

The communication circuit 48 receives data transmitted from an external device via the connector 14 and the interface 26, and outputs transmission data output from the control unit 43 to the external device.

FIG. 6 is a configuration diagram of the register of the RAM 46. The RAM 46 includes a register area 46a, a telephone number memory 46b, a schedule memory 46c, a free data memory 46d, and a character memory 46e.

The register area 46a has a display register DP for temporarily storing display data, a time register T for storing the current time to be measured, a mode register M for storing a numerical value corresponding to the operation mode, and a plurality of flags. Registers N, L, F ₀ , F ₁ and registers P, Q, R for specifying a memory read address are provided.

The mode register M is composed of, for example, a quaternary counter. In the mode register M, “0” is displayed in the time display mode, and “1” is displayed in the telephone number data display mode. "2" is set in the mode and "3" is set in the free data display mode.

The register N is a flag register which becomes "0" in the data display mode and "1" in the data setting mode. The register L is a flag register that is “1” in the external character setting mode and “0” in other cases.

The register F ₀ is a flag register which becomes “1” in the reception mode and the register F ₁ is “1” in the transmission mode. The registers P, Q, and R are a telephone number memory 46b and a schedule data memory 46c, respectively.
And a display pointer for designating and displaying one of a plurality of data stored in the free data memory 46d.

The telephone number memory 46b is a memory for storing a plurality of telephone number data in which a name, a reading, an address, a telephone number, and a comment are grouped in a set in alphabetical order or in Japanese syllabary.

The schedule memory 46c is a memory for storing a plurality of schedule data in which date and time and schedule contents are combined in order of date and time. Free data memory 4
6d is a memory for storing a plurality of arbitrary comment data in the input order.

The character memory 46e is a memory for storing a plurality of sets of data of a display font (character pattern such as characters and symbols) created by a user and character code data of the display font.

FIG. 7 is a diagram showing the structure of one set of data in the character memory 46e. The JIS code of a character is stored in the first 2-byte memory area, and the user creates the JIS code in the subsequent 32-byte memory area. The display font data of the external character is stored.

Next, the outline of the operation of the embodiment having the above configuration will be described with reference to the flowchart of FIG. First, in step S1 of FIG. 8, it is determined whether or not the register F ₀ is “1”. If F ₀ = 1, step S2
Is executed.

If it is determined in step S1 that F ₀ = 0, the flow advances to step S3 to determine whether or not the register F ₁ is "1". If F ₁ = 1, the transmission process of the next step S4 is executed. In this transmission processing, the communication circuit 48 outputs data sent from the control unit 43 to the outside.

When the receiving process (S2) and the transmitting process (S4) are completed, or when the registers F ₀ and F ₁ are both “0”, the process proceeds to step S5 to determine whether a key operation has been performed. I do. When the key is operated, the key processing of step S6 is executed. At this time, if the key has not been operated, the process proceeds to step S7, and it is determined whether or not it is time for timing. If the timing is the timing, the timing process of the next step S8 is executed, and the current time of the timing register T of the RAM 46 is updated.

Here, the contents of the key processing in step S6 will be described with reference to the flowchart in FIG. First, in step S11 in FIG. 9, it is determined whether or not the operation is the operation of the SA key. If the operated key is the SA key, the operation mode is switched by incrementing the value of the mode register M in the next step S12. That is, the user operates the SA key to sequentially switch among the time data display mode of M = 0, the telephone number data display mode of M = 1, the schedule data display mode of M = 2, and the free data display mode of M = 3. be able to.

The operation performed in the determination of step S11 is S
If it is not the A key, the flow advances to step S13 to determine whether or not the operation is the SB key. If the SB key has been operated, it is determined in next step S13 whether the value of the mode register M is "1", "2" or "3". If the value of the mode register M is any one of M = 1, 2, and 3, the page change processing of step S15 is executed. In this page change processing, the display pointer P, Q or R of the corresponding display mode is incremented, and the data of the next page is displayed.

That is, in each of the display modes of the telephone number data display mode, the schedule data display mode, and the free data display mode, the SB key is operated to store the data in the telephone number memory 46b, the schedule memory 46c, and the free data memory 46d. The stored data can be displayed in order.

The operation performed in the determination of step S13 is S
If it is not the B key, the flow advances to step S16 to determine whether or not the operation is the SC key. If the key operated at this time is the SC key, it is determined in the next step S17 whether or not the register N is "1". When the SC key is operated in the data setting mode of N = 1, "0" is set in the register N in the next step S18, and the operation mode is switched to the data display mode.

When the SC key is operated in the data display mode of N = 0, the process proceeds to step S19, where "1" is set in the register N, and the operation mode is switched to the data setting mode.

That is, the data setting mode and the data display mode can be alternately switched by operating the SC key. If it is determined in step S16 that the operated key is not the SC key, the flow advances to step S20 to determine whether or not the operated is the SD key. If the operated key is the SD key, it is determined in step S21 whether or not the register N is "1", and further in step S22, it is determined whether or not the register L is "0".

When N = 1 and L = 0, the SD key is operated in each of the telephone number data, schedule data, and free data setting modes. In this case, the data is set in the next step S23. Move the digit to the next. That is, in the data setting mode, it is possible to arbitrarily select the set digit of the data by operating the SD key.

If N = 1 and L = 1 in the determination in step S22, the display unit 13 is displayed in step S24.
Is inverted from on to off or vice versa.

In other words, when N = 1 and L = 1, the external character setting mode is set. In this case, the display key is operated to specify the display dot to white or black, and then to S1 to S4 to be described later.
By operating the cursor movement key of No. 4, an arbitrary display font can be created.

The operation performed in the determination of step S20 is S
If not, the flow advances to step S25 to determine whether or not the operation is the operation of the SE key. If the operated key is the SE key, it is determined whether or not the register N is "1" in step S26, and whether or not the register L is "1" in step S27.

If N = 1 and L = 1, it means that the SE key has been operated in the external character setting mode. In this case, "0" is set in the register L in step S28, and the telephone number and the like are set. Switch to data setting mode.

On the other hand, when the register L = 0, the SE key is operated in the data setting mode.
In this case, in step S29, the register L is set to "1" to switch to the external character setting mode, and at the same time, the character code data of the character displayed blank, that is, the received J
The IS code data is transferred to the character memory 46e. Further, in the next step S30, four types of cursors, up, down, left and right, corresponding to the S1 to S4 keys are displayed.

The operation performed in the determination in step S25 is S
If it is not the E key, the process proceeds to step S31, and it is determined whether or not the cursor movement keys of S1 to S4 have been operated. If the operated key is the S1 to S4 key, the next step S3
At step 2, it is determined whether the register N is "1" or not and the register L is "1".

If N = 1 and L = 1, the user operates the cursor movement keys S1 to S4 to register an external character in the external character setting mode. In this case, in step S33, At this time, the white or black dot data at the position designated by the cursor is set as font data in the character memory 46e.

Here, a description will be given of a case where the display font of the kanji corresponding to the received character code data is not stored in the font memory 47 and the user creates the display font of the kanji using the external character function. I do.

Now, it is assumed that the display font of the kanji “hinoki” has not been stored in the font memory 47 when data including character codes such as kanji and kana as shown in FIG. 11 is received from the external device. . In this case, the display as shown in FIG. 12 is performed by the reception process described later, and the position of the kanji character “HI” having no display font is blank-displayed.

When the user looks at the display and creates a blank kanji display phone, the user first operates the SC key to switch to the data setting mode, and then operates the SE key. Switch to external character setting mode.

When the mode is switched to the external character setting mode, the received character code data of the blank displayed kanji is transferred to an empty character code memory area of the character memory 46e, and at the same time, as shown in FIG.
Whether the S4 key corresponds to the up / down or left / right key is displayed.

In this state, the user operates the SD key to designate a black dot, and then operates the S1 to S4 keys to create a character pattern of "cypress" to create a character memory 46.
e. FIG. 14 shows the display font of one character vertically.
Shows the display font when represented by 16 x 15 horizontal dot data.

In this case, since the character code of the kanji “cypress” displayed as a blank character is set as the character code of the display font created as an external character, the user does not need to know the character code to create the display font. And the character code can be registered in the memory as a set of data.

As a result, the character memory 46e stores the display font of the kanji "hinoki" created by the user together with the received character code, so that the next time the character code of "hinoki" is received, the character memory 46e
The display font of "cypress" is read out and displayed.

When there are a plurality of blank displays,
For example, if the blank display for which the display font is to be created is blinked in order, and if the external character is set in that state, the character code at the blinking position is transferred to the character memory 46e. Can be stored in association with the display font created by the user and the character code corresponding to the display font.

Next, an operation when data is received from an external device in a state where a user has created a display font using the external character function will be described with reference to a flowchart of a reception process in FIG.

In step S41 of FIG. 10, the data received from the external device is temporarily stored in the RAM 46. Next, in step S42, it is checked whether or not the received character code exists in the font memory 47. If the character code exists in the font memory 47, the next step S4
At 3, the display font corresponding to the character code is read and displayed on the display unit 13.

The corresponding character code is stored in the font memory 47.
If not, it is checked in step S44 whether the character code is registered in the character memory 46e. If the received character code is registered in the character memory 46e, in step S45,
The display font corresponding to the character code is read from the character memory 46e and displayed on the display unit 13.

For example, as described above, when the same character code is received next while the display font of the kanji “hinoki” is registered as an external character, the display font of the kanji “hinoki” is read from the character memory 46e. Is displayed.
Therefore, once the display font is created, the kanji corresponding to the character code is automatically displayed thereafter, without the user having to perform any key operation.

If the corresponding character code does not exist in either the font memory 47 or the character memory 46e, the corresponding character is blank-displayed in step S46.

As described above, according to the above embodiment, the display font created by using the external character function can be stored in the character memory 46e in correspondence with the corresponding character code. Therefore, the next time the same character code is received, the display font corresponding to the character code is read from the character memory 46e. An operation such as display is unnecessary, and the operation is simplified.

The present invention is not limited to the electronic wristwatch described above, but can be applied to a personal computer, a word processor, an electronic organizer, a pager, a wireless device and the like having a data communication function. In addition, a function for registering external characters is provided, and JIS code data can be entered and stored at the time of registration so that the data can be automatically displayed at the time of communication.

Further, the display font is not limited to the kanji display font, but may be a display font for characters, symbols, etc. other than the language and kanji.
Further, the method of setting the external character is not limited to the method described in the embodiment, but can be realized by another method.

The display method when there is no display font may be another display method instead of the blank display.

[0065]

According to the present invention, even when the display font corresponding to the character code or the like received from the outside is not stored in the ROM or the like on the receiving side, the display is performed using the display font created by the user. Not only can you do
You can easily create fonts.
