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

Bit 4 which is the minimum recording unit in both figures
4 together form an information track 42. The information track indicates the end of the information track and the end bit 43 which also serves to identify the adjacent track, the recording data 42, the beginning of the recording data, and a reference indicating that the read head is on the track. A bit 41 and a portion 40 for generating a clock for information reproduction are added to form one track 50. A plurality of this track 50 are collected, and block 45
To form. A plurality of blocks 45 are arranged to form the entire recording area. The head track of each block has recorded therein information indicating that it is the head of the block, information about what screen it is, and the like.

Now, the size of the bit 44 is about 10 μm × 1.
The size of the card is 86mm x
Assuming that the storage area is 54 mm and about 80% of the entire surface of the card is about 6.4 × 10 ⁷ bits = 5.8 MBytes.
(1 Byte = 8 bits) can be recorded.

Even if the area (format area) in which the information required for information reproduction is recorded is set to about 20%, the recordable capacity is about 4.6 MBytes.
When recording alphanumeric, one byte is used for each character, so the number of characters that can be recorded is approximately 4,600.
It becomes 10,000 words. In addition, it is possible to record 23 million words even with Kanji, which requires 2 bytes for each character. This means that one phone book of about 500 pages can be recorded. Further, if the size of 1 bit is made smaller, more information can be recorded.

FIG. 5 shows an example of the information reading section of the optical card reader. The optical card 37 is translated by the belt drive 61 along the track alignment direction A. Light emitted from a light source 62 such as a laser illuminates a track on the optical card 37 by an illumination lens 63. The image of the illuminated track is transferred to the one-dimensional sensor array 6 by the imaging lens 64.
The information on the track is read by being projected onto the cell of No. 5.

Further, by the forward movement of the optical card 37 in the A direction and the movement of the optical head 60 in the C direction, information on the entire surface of the card can be reproduced. This also allows random access of information.

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 various features which conventional memory media do not have, such as a large recording capacity, portability, easy handling, and high reliability due to non-contact reading. .

Further, the optical card memory manufacturing method can be manufactured at a very low price because the conventional printing technique can be used as it is, and in addition to the telephone directory, the distribution cost is included in terms of size and weight. Significant price reduction is possible.

FIG. 6 shows the operation of the apparatus when it is started. First, the main power supply is turned on, the line is switched to a telephone, and the transmission, reception, and copy lamps (not shown) are turned off. If the function key is turned on, the function mode described later is executed. If it is not turned on, it is determined whether there is a ringing signal. If there is, it is determined whether it is a support for rewriting the telephone book, and the result is In accordance with the processing, the telephone book is rewritten or received. Further, if the ringing signal is not detected, it is judged whether it is the transmission time or the reception time, and if it is, the time designated automatic transmission or reception is performed and other processing is executed. I won't mention it.

FIG. 7 shows details of the function mode. First, it is determined whether the optical card key 31-4 is turned on (step 61), and if it is turned on, it is determined whether the optical card 37 is set in the optical card reader / writer 36 (step 62). ). If set, the phonebook is searched. That is, if the 2 keys of the numeric keypad are pressed, the search is advanced one by one (steps 64 and 7).
2) If the 8 key is pressed, the characters are returned one by one (steps 65, 73), and if the 4 key is pressed, the upper character is advanced by one such as A → i (steps 66, 74). ),
If the 6 key is pressed, the next higher character is returned by one such as A → A (steps 67 and 75). As an example, when searching for Yutaka Iida, the result is as shown in FIG. Here, in order to display Mr. Iida's address and telephone number, the address key 31-2 and dial key 31-3 may be pressed (steps 68 to 70, 7).
6-78). When the function key 31-5 is pressed again to cancel the function mode, the display 32 becomes the time display (steps 71 and 79). If the * 1 key is on, the communication result output mode is set (step 80). That is, it is judged whether or not the optical card is mounted in the device (step 81), and if it is mounted, the communication result recorded in the communication recording area of the optical card is stored in the RAM 4
To the RA (step 82) and RA if not installed
The data transfer area from the M4 optical card is cleared (step 83). Then, the communication result data stored in the RAM is printed out (step 84). Here, when the optical card is mounted, both the communication result data of 20 communications directly recorded in the RAM 4 and the data of 200 communications transferred from the optical card (220 communications) are printed. If no optical card is installed, print only 20 communications. If the * 2 key is on, the time designated automatic transmission is recorded. That is, the transmission time is set by the ten key 31-1, the transmission partner is searched and set by the method described above, and the transmission contents are registered (steps 85 to 88). If the * 3 key is on, the time designated reception is registered. That is, the reception time is set by the ten keys 31-1, and the reception partner is searched and registered by the above-mentioned method (steps 89 to 91). The designated time is set in the timer, and the destination is stored in the optical card from the RAM 4. In addition, registration of the current time, registration of the ID number at the time of automatic reception, and the like are performed as necessary (step 92).
Also, multiple time specifications can be set.

FIG. 9 shows the operation of registering the transmission contents. First, it is determined whether the optical card is attached to the device (step 100), and if it is attached, it is determined whether the image registration key 31-7 or the voice registration key 31-8 is turned on (step 101). , 102), image registration key 31-7
If is turned on, the document reading is started when the document is set in the reading unit, and the CPU 2 stores the coded image information such as MH in the optical card (steps 104 to 10).
6). If the voice registration key 31-8 is turned on, voice is input from the handset 34, and digitally encoded voice information is stored in the optical card via the NCU, the voice recording / reproducing circuit 38, and the RAM 4 (step 103). .

FIG. 10 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. Further, data for 200 communications is recorded in the communication recording area 37-3 of the optical card. Then, the destination, telephone number, date and time, communication start time, communication time, etc. of the other party are recorded in the communication recording area 37-3. Further, 37-1 records the update date and time of the telephone directory, and 37-2 records the telephone number written in the telephone directory. A designated time 37 for automatic transmission / reception, a destination, a transmission content number, and the like are recorded in 37-4. Audio data and image data for transmission are recorded in 37-5 and 37-6 with an identification number, respectively.

FIG. 13 shows the operation during automatic transmission. First,
When the timer 5 outputs the signal at the set time (step 131), the transmission / reception program area 37- of the optical card
3 is read, the transmission start time recorded therein is compared with the current time, and which data is to be transmitted and where is determined. Then, the data to be transmitted is read out from the image data and audio data recorded in the areas 37-4 and 37-5 based on the identification number and transmitted (steps 132, 1).
33). Then, it is judged whether or not the transmission of all data has been completed (step 134), and if not completed, the process waits until the next timer time is reached.

FIG. 11 shows the management of communication record data during transmission and reception. First, if there is transmission / reception, the current date and time is read from the clock 47 and recorded in the communication recording area of the RAM (steps 113 to 113). Then, transmission or reception processing is performed (steps 114 to 116), the relay CML is turned off, and the telephone line is turned off (step 117). Then, the other party's data (name, telephone number, etc.) is stored in the RAM (step 118), the current time is read from the clock 47, and the communication time is calculated and stored in the RAM (steps 119, 12).
0).

Next, FIG. 12 shows updating of the telephone directory.
First, it is determined whether or not it is attached to the optical card device (step 121), and if it is set, 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 122). If they match, the number of update data sent from the line is set in the RAM (step 123), and is recorded in the area of the optical card telephone directory in accordance with the update data sent from the line 33 (step 124). The set number is updated (step 125). Then, the next update date and time is recorded in the area 37-1 of the optical card (step 106). In addition,
The update data is transmitted from the line 33 to the CPU 2 via the NCU 15 and the modem 14.

The communication result can be output by printing arbitrary communication record data by inputting from the operation unit. This can be easily accomplished by counting the end code stored in RAM. RAM
Also, the number of communication record data stored in the optical card may be as many as the capacity allows.

The telephone directory and the transmission contents may be managed by different optical cards. In this case, another optical card recording / reproducing device is required to manage two cards at the same time.
