It is composed of a matching circuit 27 that compares the outputs of the above and checks whether they match, a row counting circuit 28 that counts the number of rows, an MH encoding circuit 29, and an MH decoding circuit 30.

It is assumed that the answering machine function is selected by a switch (not shown) of the device. When a call signal is received through the telephone line 48, the call detection circuit 18 shown in FIG. 2 informs the CPU 1 through the call signal line 55 of the bus 46 that there is a call. Receiving this notification, the CPU 1 operates a hook switch (not shown) in the telephone line 17 via the signal line 51 of the bus 46 to bring it into an off-hook state, and connects the line. After that, the CPU 1 sets the relays 20 and 21 to a− via the switching signal line 52 of the bus 46.
It is set on the side of a ", b-b", c-c ", d-d" to enable transmission of voice and drawing information. (Hereinafter, two types of voice and drawing information are transmitted. May be collectively referred to as a message.) Also, switches 61 and 62 are S1-S.
Set to 1 ', S2-S2' side to enable drawing information to be received.

Information received (ie message) is relay 20, 2 wire 4
It is input to BEF12 and BPF15 via the line converter 11. The voice is picked up by the BEF 12 and input to the telephone circuit 17 via the 2-wire 4-wire converter 11 'and the relay 21, and then the signal line.
Sent to 50. On the other hand, a drawing signal is extracted from the information input to the BPF 15, demodulated into digital information by the modem 16, and sent to the signal line 54 of the bus 46. The CPU 1 decodes this information into coordinate values by the zone code decoding circuit 8 shown in FIG. 1 and stores the data in the corresponding address of the display RAM 5. At the same time, the encoded data before being input to the zone code decoding circuit 8 is transmitted from the telephone circuit 17 to the signal 50.
It is recorded in the cassette tape recorder 57 together with the sound transmitted to the cassette tape recorder 57. In this recording, the sound is recorded in the left channel using the stereo head, and the encoded drawing data is recorded in the right channel again modulated by the modulator / demodulator (not shown). When data that the caller intends to terminate is received,
The CPU 1 sets the relays 20 and 21 of FIG. 2 to aa ', bb', c-
After setting to the c ', d-d' side and ending the drawing information receiving function, a hook switch (not shown) in the telephone circuit 17 is turned on to disconnect the telephone line.

After this, the 0-line detection register 24 in FIG. 3 is set to “0”, and the display data read circuit 22 causes the bus 46 to operate.
The display RAM 5 shown in FIG. 1 is controlled via the CPU to read the information recorded in the display RAM 5, and the data for one line of the display screen is temporarily recorded in the read data register 23 via the bus 47. This data is input to the 0 line detection circuit 25, and it is checked whether or not all the lines are "0". The data is "1"
And "0". When "1", the corresponding dot on the display screen is turned on (that is, displayed), and when "0", the dot is turned off (that is, not displayed). Next, as a result of this investigation, if the data of the input line is all "0"
If so, the 0-line detection circuit 25 determines that the detection is a match circuit.
27, and compares with the output of the 0 line detection register 24.
The coincidence circuit 27 inputs "0" to the row count circuit 28, which indicates that they are coincident when both inputs are 0. After this,
The output of the 0 line detection circuit 25 is written in the 0 line detection register 24. Then, one after another, the display data reading circuit 22
Reads data from the display RAM 5 and repeatedly detects 0 line by the 0 line detection circuit 25.

0 line detection circuit when all non-zero lines are detected
25 inputs it to the matching circuit 27. The output of the 0-line detection register 24 is "0" because the previous line was all 0. Therefore, the matching circuit 27 detects that the inputs do not match and outputs "1" indicating this to the row counting circuit 28.

When the row count circuit 28 detects that the input has changed from "0" to "1", the operation of the 0 line detection circuit 25, the 0 line detection register 24, and the match circuit 27 is stopped by a control signal (not shown). , And row detection circuit 26, MH encoding circuit 29
To operate.

Then, the display data read circuit 22 further reads the data from the display RAM 5 and temporarily records the data in the read data register 23 via the bus 47. The data read at this time is read in a fine unit such as one line of data on the display screen divided. When the row detection circuit 26, which performs the number of times of reading, counts and detects that the read data corresponds to one line of the display screen, it sends a predetermined signal to the row counting circuit 28 and the row counting circuit 28. Counts one line. At the same time, data is input from the read data register 23 to the MH encoding circuit 29, encoded, and stored in the memory 10 of FIG.

When the row counter circuit 28 counts a predetermined number of rows, the row counter circuit 28 stops the operations of the row detection circuit 26 and the MH encoding circuit 29. For example, when the pitch of the liquid crystal display cells of the liquid crystal display device 3 in FIG. 1 is set to 0.3 mm and the value of 80 is set in the row counting circuit 28, a 24 mm wide area is taken out from the display screen and stored in the memory 10. It

Next, the memory 10 has a memory capacity of 2 as shown in FIGS. 4 (a) and 4 (b).
It consists of two tables.

The data coded by the MH coding circuit 29 (hereinafter referred to as index data) is stored in a certain block of the table shown in FIG.
Note that this block is composed of a data recording area 33 in which encoded index data is recorded and a pointer 34 indicating up to where the data is stored (that is, the range of the block). The index data corresponding to one received message (voice and drawing information) is stored.

Next, CPU1 receives the message (voice and drawing information)
As information regarding the above, the following information is stored in a certain block of the message reception table 31 shown in FIG.

That is, the number of the received message is stored as the received message number, the address of the index data encoded and stored in the memory 10 is stored in the index pointer, and the voice and the drawing information are recorded. The location on the cassette tape is stored in the registration data pointer, and the received time is read from the clock circuit 35 and stored in the reception time buffer.

That is, the message reception table 31 is a table for managing each message received during absence. Each time a message is received and voice and drawing information are recorded during absence, the message is recorded in the table 31. The information for referencing is stored. The received message number, index pointer, registration data pointer, and reception time buffer are collectively referred to as the index table 32.

When the above procedure is completed, the CPU 1 searches the message reception table 31 in the memory 10 and displays the index of the registered message on the liquid crystal display device 3. This method will be described below.

The CPU 1 extracts the index pointer in the index table 32 in order from the beginning of the message reception table 31 in the memory 10 and obtains the address in the memory 10 where the index data is stored. Then, the coded index data is read from here and the MH shown in FIG. 3 is read.
The decoding circuit 30 decodes the bit data of the display screen.
This bit data is sequentially written to the address corresponding to the display location of the display RAM 5, and then displayed on the liquid crystal display device 3 by the display control circuit 6.

Thus, a plurality of indexes (that is, the first part of the received message) are displayed on the screen of the liquid crystal display device 3.

This display screen is shown in FIG.

In FIG. 5, the index display area 36 is an area in which the index (the first part of the received message) is displayed, and the time display area 37 is shown in FIG. 4 (a).
This is a part where the reception time stored in the reception time buffer shown in is displayed.

Furthermore, when the number of indexes to be displayed is more than can be displayed on this one screen, "previous page" and "back page" are displayed in the display areas 38 and 39. Then, when the input pen 4a shown in FIG.
Reads the index data “before” or “after” the index currently displayed in the message reception table 31 from the memory 10 and displays it in the same manner.

Here, if the user wants to display the entire received message, he / she uses the input pen 4a to point to the index at which the entire message is to be displayed or the displayed index. The CPU 1 calculates the corresponding message number from the input coordinate values, knows the recording location recorded on the cassette tape recorder 57 of FIG. 1 by the registration pointer in the index table 32 of FIG. And the drawing information is reproduced. The sound is output from a speaker (not shown). The drawing information is digitally demodulated and then decoded into coordinate values by the zone code decoding circuit 8, and the data is recorded by the CPU 1 in the corresponding address of the display RAM 5. This will display the entire received message.

When the whole is displayed, as shown in FIG. 6, “print” and “end” are respectively displayed on the display units 44 and 45, and if necessary, “print” is instructed and displayed on the liquid crystal display device 3. The information can be printed by the printing device 42. Also, if "end" is designated, the display returns to the index display state.

As described above, according to this embodiment, the first part of the message received when the user is absent is displayed as the index. Usually, when sending a message, first,
You can attach information to who and with what requirements, who wants to send a message. Therefore, since this part is displayed, you can easily understand what kind of message has arrived at a glance, and you can display the whole message by just pointing on this display, you can easily check the target message effective.

〔The invention's effect〕

According to the present invention, the drawing information received at the time of answering machine is recorded, and a part of the drawing information from the drawing information (e.g., as a message normally left when the other party is absent, what kind of message, who and when) As you can see if you contacted me, I write the message, name, etc. in the first part, so dozens of lines or white lines that are the first part of the drawing information and exclude the first margin part are used as indexes. By taking out and storing in the index storage means,
A plurality of the indexes can be displayed on the display means at the same time. Further, by inputting a desired index from the plurality of displayed indexes by the input means, the specified index can be taken out. The original drawing information can be displayed on the display means.

In this way, by displaying a plurality of indexes on the display unit at the same time, the user can quickly grasp the contents of the plurality of drawing information received, and display the information required by the user. By pointing while watching, the entire information is displayed immediately, so that the desired information can be obtained efficiently and swiftly. Moreover, since it is not necessary to print all the received information, the recording paper is not wasted for unnecessary information.
