Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a communication device, and particularly to a communication device having a storage medium.

[Prior Art] In recent years, communication devices such as telephones are required to have higher functionality, and various functions are being added.

For example, you can store multiple phone numbers and call the desired party with a few operations. however,
Generally, the amount that can be stored is about 20 at most, and even if the number were increased, it would be difficult to select a desired partner. It is also conceivable to use a magnetic card to store telephone numbers, but its capacity is not so large, and floppy disks or the like would increase the size of the device and increase costs.

It is also desired to use the device outdoors, and for this purpose, a storage medium that is easy to carry and has high maintainability is desired.

Additionally, when using it as a telephone directory, updating of telephone numbers must also be considered.

[Objective] The present invention was made in view of the above points, and it simplifies communication procedures, uses a storage medium with excellent portability and maintainability,
It is an object of the present invention to provide a communication device with which information can be easily updated.

[Example] An example of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the overall configuration of a communication device according to this embodiment. In FIG. 1, a crystal oscillator 1 generates a reference clock for the entire device.

UPI 12 is a key human power switch 31. liquid crystal display LC
Controls D32.

A modem 14 modulates and demodulates image data and transmits and receives procedure signals for facsimile communication procedures.

Reference numeral 15 denotes a network control unit (NCU), which switches the connection of the line 33 by a relay CML (not shown) on the telephone 34 side or the modem 14 side.

16 is a dialer, which connects the line 33 according to the telephone number data of the communication destination outputted from the CPU 2 via the PPl7.
Sends a dial signal to.

Reference numeral 18 denotes a speaker drive circuit, and 19 a speaker, which outputs the signal from the line 33 as sound when the relay 8 is turned on.

36 is a device for recording or reproducing data on the optical card 37.

FIG. 2 is a diagram showing the key manual switch 31 and liquid crystal display 32 of FIG. 1. 31-1 is a group of Tenki, 31-2
is the key to press to display the address, 3 knee 3 is the key to press to display the telephone number, 31-4 is the key to press when using the optical card, 31-5 is the key to press to enter the function mode, 31-5 is the key to press to display the name.

FIG. 3 shows an example of the format of the optical card 37, and FIG. 4 is a partially enlarged view.

In both figures, several bits 44, which are the minimum recording unit, are collected to form an information track 42. The information track includes an end bit 43, which serves both to indicate the beginning of the information track and to identify adjacent tracks, and a reference (recorded data 42) that indicates the beginning of the recorded data and indicates that the read head is on the track. bit 4
1, and a section 4° for generating a clock for information reproduction is added to form one track 50. A plurality of these tracks 50 are assembled to form a block 45. A plurality of blocks 45 are arranged to form the entire recording area. Note that the first track of each block records information indicating that it is the beginning of the block, information on what screen number, etc.

Now, assuming that the size of the bit 44 is approximately 10 μm x 10 am, the size of the card is 86 mm x 54 mm, and the storage area is approximately 80% of the entire surface of the card, approximately 6.4 x 107 bits = 5.8 MByte (I By
te=8bit) can be recorded.

Even if the area (format area) in which information necessary for information reproduction is recorded is about 20%, the recordable capacity is about 4.6 MB. When recording alphanumeric characters, one byte is used for each character, so the number of characters that can be recorded is approximately 46 million words.

In addition, even kanji that require 2 bytes for one character are 230
Can record 00,000 words. This means that the equivalent of one telephone directory with approximately 500 pages can be recorded. Furthermore, if the size of one bit is made smaller, more information can be recorded.

FIG. 5 shows an example of the information reading section of the optical card league.

The optical card 37 is moved in parallel along the track alignment direction A by a belt drive 61. Light source 6 such as laser
The light emitted from the optical card 2 illuminates the tracks on the optical card 37 through an illumination lens 63. The image of the illuminated track is projected by the imaging lens 64 onto the cells of the -dimensional sensor array 65, and the track information is read.

Furthermore, the reciprocating movement of the optical card 37 in the direction and the optical head 60
By moving in the C direction, the information on the entire surface of the card can be reproduced. This also allows for random access to information.

Note that the format of the optical card is not limited to this, and various formats can be applied.

A memory system using such an optical card has many features not found in conventional memory media, such as large storage capacity, portability, ease of handling, and high reliability due to non-contact reading.

In addition, optical card memory can be manufactured at a very low cost because conventional printing technology can be used as is, and compared to a telephone directory, its size and weight are significantly lower, including distribution costs. It is possible to price it.

Figure 6 shows the operation of the wooden lid when starting up. First, the main power is turned on, the line is switched to a telephone line, and the transmitting, receiving, and copying lamps (not shown) are turned off.

If the function key is turned on, the function mode described below is executed, and if it is not turned on, it is determined whether there is a ringing signal or not, and if there is, it is determined whether or not it is an instruction to rewrite the telephone directory, and based on the result. The telephone directory is rewritten or the reception process is performed accordingly. Further, if a calling signal is not detected, other processing is executed, but will not be described in detail here.

FIG. 7 shows details of the function mode.

First, it is determined whether or not the optical card key 31-4 is turned on (step 61). If it is turned on, the optical card key 31-4 is turned on.
7 is set in the optical card reader/writer 36 (step 62). If set, the phone book will be searched. That is, if the (2) key ° on the numeric keypad is pressed, the search proceeds one person at a time (steps 64 and 72).
), if the lp key is pressed, go back one character at a time (step 65.73); [If the J key is pressed, the highest character advances by one from A to A (step 66.74) )
, [If the @ key is pressed, the highest character moves back one character, such as Ea (steps 67 and 75). For example, when searching for Toyo Iida, the search will be as shown in Figure 8. Here, in order to display Mr. Iida's address and telephone number, all you have to do is press the address key 31-2 and the dial key 31-3 (step 68 to
70.76-78). Function key 31-5 again
When you press to cancel the function mode, the display 32
becomes a time display (steps 71 and 79). Furthermore, if the Shikita key is on, the mode is set to output communication results (step 80). That is, it is determined whether the optical card is installed in the device (step 81), and if it is installed, the communication results recorded in the communication recording area of the optical card are transferred to the RAM 4 (step 82). If not, the area for data transfer from the optical card in RAM 4 is cleared (step 83). The communication result data stored in the RAM is then printed out (step 84).

Here, when the optical card is installed, both the communication result data for 20 communications directly recorded in the RAM 4 and the data for 200 communications transferred from the optical card (220 communications) are printed. If no optical card is installed, only 20 communications will be printed.

FIG. 9 shows a memory map of the RAM 4 and the optical card 37. In the communication recording area 4-1 of the RAM 4, new data is always sequentially recorded for 20 communications.

Furthermore, data for 200 communications are recorded in the communication recording area 37-3 of the optical card. And communication record area 37-
3, the other party's destination, telephone number, date and time, communication start time, communication time, etc. are recorded. Further, 37-1 records the update date and time of the telephone directory area, and 37-2 records the telephone number listed in the telephone directory.

FIG. 10 shows management of communication record data during transmission and reception. First, if there is a transmission or reception, the current date and time is read from the clock 47 and recorded in the communication recording area of the RAM (steps 91 to 9).
3). Then, transmission or reception processing is performed (steps 94-
96), turn off the relay CML and turn off the telephone line (
Step 97), then store the other party's data (name, telephone number, etc.) in the RAM (Step 98), read the current time from the clock 47, calculate the communication time, and store it in the RAM (Steps 99, 100).

Next, FIG. 11 shows updating of the telephone directory.

First, it is determined whether or not the optical card is installed in the device (step 101). If it is, the update date and time is read from the update date and time data area 37-1 of the optical card and compared with the current date and time (step 102). If they match, the number of update data sent from the line 33 is set in the RAM (Step 103), and the number of update data sent from the line 33 is also recorded in the telephone directory area of the optical card (Step 104). The update is performed by the number of times (step 105). Then, the next update date and time is recorded in the area 37-1 of the optical card (step 106). Note that the update data is transmitted from the line 33 to the NCU 15. It is transmitted to the CPU 2 via the modem 14.

Further, the communication results can be outputted by inputting from the operation unit to print arbitrary communication record data. This can be easily accomplished by counting the end codes stored in RAM. Further, the number of pieces of communication record data stored in the RAM and optical card may be any number as long as the capacity allows.

Alternatively, the telephone directory and communication results may be managed using separate optical cards. In this case, another optical card recording/reproducing device is required to manage the two cards simultaneously.

[Effects] As explained above, according to the present invention, communication destinations can be easily searched using a recording medium with excellent portability and maintainability.
Furthermore, it is possible to realize a communication device in which information regarding the communication partner can be easily updated.
