A second step of retrieving whether a control code of a date is received; and when the output date is determined in the second step, accessing the schedule data corresponding to the output date from the memory in which the schedule data is stored is converted and transmitted to the picture data. The third step is made.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The schedule input according to the present invention is to be able to input in the form of numbers and letters or documents using the keyboard or the scanner when the fax is in the standby state.

If the operator selects a function key in the key input section 10 in the standby state (step 62), the CPU 14 displays a menu on the display 34 (step 64) and the schedule document is displayed on the scheduler 30. Search if it is set (step 66). If the search result document of step 66 is set in the scanner 30, the CPU 14 controls the speech signal processor 32 (step 68) to read the signal output from the speech signal processor 32. do. The CPU 14, which inputs the signal output from the talk signal processor 32, binaryizes the talk signal (step 70) and stores it in the auxiliary memory 26 (step 72).

The CPU 14, which reads the contents of the original set as described above and stores them in the auxiliary memory 26, outputs and displays a message for inputting a key on the display 34 (step 76). At this time, if the user continuously inputs data of year, month, day and schedule using a key, the CPU 14 searches whether the input key is a letter key (step 80), and if it is a letter key, an ASCII code (Step 82) is stored in the RAM 44 in the memory unit 20, and in the case of a numeric key, it is converted into a BCD code (step 84) and stored in the RAM 44. The CPU 14 storing the key code value input in step 86 in the RAM 44 searches whether the input has ended (step 88), and when it is finished, inputs the schedule data stored in the auxiliary memory 26 as a document. The processed data is stored in the RAM 44 in the memory unit 44 (step 90). If the input is not completed in step 88, the CPU 14 jumps to step 78 and repeats the process.

In this case, when the contents of the auxiliary memory 26 are stored in the RAM 44 of the memory unit 20 in the step 90, the contents are stored in an area by date (time) by key input. For example, if the year, month, and day are input as keys, the year, month, and day are stored in the memory as shown in FIG.

Therefore, when the year, month, and day keys related to the schedule are input, the input number is converted into a 4-bit BCD code and stored in the RAM 44 in the format as shown in FIG. ) Is stored in the RAM 44 and stored in the date, time, and the predetermined contracted form.

If the document is not set in step 66 described above, the CPU 14 searches (74) for the deletion key. If it is not the delete key in the searching step, the CPU 12 displays a message for inputting the key on the display 34 as described above.

When the user inputs the date, time, and work content according to the contents of the keystroke key input message (step 72), the CPU 12 searches for the letter as described above (step 80). Convert to Kercode (ASCII). At this time, the coded data is sequentially stored in the RAM 44 in the memory unit 20 under the control of the CPU 12.

In the above, the numeric input from the key input unit 10 uses the ten keys (1 to Ø) for dialing, and the alphabetic characters may be input in accordance with the contracted method.

Therefore, if the date and time of the schedule and the work content are input as numbers or letters in the key input unit 10 as described above, the schedule data are stored in the RAM 44 as shown in FIG.

On the other hand, if the function key input in step 74 is the delete key, the CPU 12 sets the current mode to the delete mode and displays a message for inputting the key on the display 34 (step 92), in response to the display message. When the user inputs the date and time of the year, month, and day of the schedule registered through the key input unit 10 (step 94), it is input to the CPU 14. The CPU 14, which inputs keys such as year, month, and day in the delete mode, searches for the contents of the RAM 44 in the memory unit 20 via the data bus 52 and the address bus 50 ( search to extract data to be deleted (step 96).

In this case, the schedule data search in step 96 is performed by comparing the year, month, day, and time input among the data stored in the form shown in FIG.

For example, first of all, the key data of the year and the year of the RAM 44 classify the same data, and then separate the ones having the same month, the same day, and the same time. Try a sequential approach.

In step 96, the CPU 14 finding the desired content deletes the selected schedule data from the RAM 44 (step 98) and returns to the initial state. At this time, in order to ensure accuracy, a content for checking whether to output the corresponding data may be displayed on the display.

After the schedule data is stored in the RAM 44 in the memory unit 20 by the above operation, the self-printing method of directly outputting the output of the stored schedule data through the printer unit 36 and a facsimile of an external remote site. You can do this in two ways: remote printing.

In the case of self-printing, a schedule of the corresponding date is displayed at the time of printing and a preset time which is immediately activated by the user's key input using the key input unit 10. Time-specified printing, which is arranged in minute order and automatically printed, is possible, which will be described in detail with reference to the accompanying drawings.

The CPU 14, which executes the operation as shown in FIG. 3, enters the time setting routine of FIG. 4 at a predetermined cycle and checks whether the facility has been set (step 98). That is, if the facility setting key is input and the facility setting is searched in step 98, and the time setting key is input, the CPU 14 inputs the current date inputted from the key input unit 16, that is, the output date and the output time T, and functions. For example, a key is searched for a key signal for manual printing immediately (steps 100, 102, 104).

If the function key is not input in step 104 of FIG. 4, the CPU 14 reads out the time data t counted from the RTC (Real Time Clock) 46 and updates and stores it in the internal memory (step 106). In operation 108, the CPU 14 compares the time data t updated in step 106 with the output time data T input in step 102 and checks whether they are the same (step 108).

When the data t and T are different in step 108, the CPU 14 continues to update the time and searches for the contents of the RAM 44 in the memory unit 20 (step 116).

The search of the RAM 44 in step 116 finds the date and the contents of the schedule data corresponding to the output date among the schedule data recorded in the form shown in FIG. For example, only the input output date in step 100 and the date of the schedule data recorded in the RAM 44 are searched for the same. When the search is completed, the CPU 14 searches for the schedule searched in the RAM 44. The data is stored in the auxiliary memory 26 (step 118).

In step 118, the corresponding output schedule data is searched for and outputs an order classification control signal to the classifier 48 to the CPU 14 stored in the auxiliary memory 26. At this time, the classifier 48 classifies the schedule data stored in the auxiliary memory 26 in the order of year, month, day, hour, and minute in response to the classification control signal (step 120) and inputs them to the CPU 14. . CPU 14, which inputs the sorted data in step 120, analyzes the code of the schedule data and fontizes the alphabetic character 24a of 8-bit ASCII code and the number 24b of 4-bit BCD code. Input is made to the font generator 24C and the 4 / 8-bit converter 24d in the data converter 24, respectively. At this time, the 4 / 8-bit converter 24d that inputs the number 24b of the 4-bit BCD code fills the 4-byte MSB preceding the input 4-bit code with 0 and converts the data into 8-bit data. ). Therefore, the font converter 24C inputs an 8-bit ASCII code alphabet 24a and an 8-bit numeric code 24b, and the font converter 24C inputs the number of the input 8-bit code ( 24b) and font data (FONT Data) corresponding to the alphabetic character 24a are output to the printer 36.

At this time, the printer 36 inputting the font data generated from the font generator 24C prints out the generated font data (step 122).

Therefore, among the saved schedule data, the data of the output date of the schedule designated by the facility setting mode is automatically printed out at the designated time.

If it is determined in step 98 that no facility is set, and in step 104 it is determined that a function key is input, the CPU 14 outputs a message to select an output menu and a message to input a key to the display 34. Display (step 110, 112).

When the date for requesting the schedule output is input to the key input unit 10 according to the message displayed in step 112, the CPU 14 inputs the date (step 114) to perform the memory search process of step 116 described above. At this time, the memory search is to search the schedule data stored in the RAM 44 area of the memory unit 20, and is executed according to the date input in step 114.

For example, steps 118 and 120 are performed by searching the schedule data stored in the RAM 44 for the same schedule date as the date input in step 114.

Therefore, by specifying a date, the user immediately prints the schedule data of the date.

The present invention allows the user to receive and print the schedule status at a remote location while storing the schedule data in the RAM 44 area of the memory unit 20 by the above-described process, and the operation thereof is as follows. .

When the user makes a call with a facsimile having the configuration shown in FIG. 1 to check the schedule remotely while the schedule data is stored in the RAM 44 in the memory unit 20 by the operation as described above, the phone of FIG. Ring signals are supplied to the lines L1 and L2.

At this time, the line connection unit 38 detects ring signals input to the telephone lines L1 and L2 and supplies them to the CPU 14, and the CPU 14 counts the input of the ring signals (step 124). The CPU 14, which counts the ring signal supplied from the line connecting portion 38, searches whether the ring count number N exceeds 9 (step 126). (Where 9 means a certain number of rings, and a nonzero natural number is sufficient)

If the number of ring counts N is greater than 9 in step 126, the CPU 14 outputs a call path forming control signal to the line connector 38 to form a call path. The line connection part 38 which inputs the said call route formation control signal forms the call route of telephone line L1, L2 in response to the said control signal. When the call path is formed as described above, signals from the telephone lines L1 and L2 are input to the modem 40 and the DTMF decoder 22.

In step 128, the CPU 14, which forms the communication path, reads the output of the DTMF decoder 22 and searches whether a DTMF code of #, for example, #, is input (step 130). .

At this time, if the DTMF signal of # is not input, the CPU 14 receives the original content transmitted from the counter station.

If a remote user presses the DTMF key of # using a telephone connected to the facsimile, it is input to the DTMF decoder 22 through the telephone lines L1 and L2 and the line connection 38. At this time, the DTMF recorder 22 converts the DTMF signal of the # input into a digital signal and inputs it to the CPU 14, and the CPU 14 determines that the DTMF signal of # is received (step 130).

Upon determining that the DTMF signal of # is input, the CPU 14 transmits a confirmation tone to the counterpart station (a user of the remote place) through the line connection unit 38 in response to receiving the signal (step 134). Search whether the date is input (step 136).

In the above state, when the remote user who listens to the acknowledgment dials the output date of the schedule using the digit key of the DTMF signal, this is the DTMF decoder through the telephone lines L1 and L2 and the line connection 38 as described above. It is input to (22). At this time, the DTMF decoder 22 converts the output date inputted by the DTMF signal into digital and outputs it to the CPU 14, and the CPU 14 receives the digits inputted from the DTMF decoder 22 immediately after transmitting the recognition sound. It is determined that the output date is input (step 136).

The CPU 14 determining that the output date has been inputted finds the schedule data of the inputted output date as described above in the RAM 44 in the memory unit 20 (step 138) and stores it in the auxiliary memory 26 (140). In step 140, the classification control signal is input to the classifier 48 (step 140).

At this time, the classifier 48 displays the schedule data stored in the auxiliary memory 26 in response to the order classification control signal output from the CPU 14. It stops in minute order and outputs to CPU14.

CPU 14, which inputs the sorted schedule data, analyzes the status of the schedule data, and outputs the 8-bit ASCII code 24a of the ASCII code to the font generator 24c of the font / graphic data converter 24. The number 24b of the 4-bit BCD code is output to the 4 / 8-bit converter 24d. At this time, the 4 / 8-bit converter 24d converts the 4-bit numeric code into 8-bit and inputs it to the font generator 24c. Therefore, the schedule data output from the CPU 14 is converted into font data by the font generator 24c as described above.

The font data converted by the font generator 24c is input to a font to image convert 24k and converted into image data (step 144). The conversion of the font data into the font data is to convert the font data into the same type of data as the reading data when read by the scanner 30, without being directly transmitted to the telephone lines L1 and L2.

The image data converted by the font / image data converter 24k is input and coded to a coder 241 for MH or MR coding the input data (step 146).

At this time, the CPU 14 controls the modem 40 to modulate the image data, that is, the schedule data output from the coder 241 in the font / hwa data converter 24, and transmit it to the remote facsimile through the line connection 38. do.

Therefore, the user who controls the output of the schedule data from the remote facsimile can print and receive the schedule from the remote facsimile.

As described above, the present invention can manage a person's work by inputting a schedule in the form of a document, and can easily manage the schedule even at a remote place by using a telephone line, thereby improving the function of the facsimile.
