To the center device via. When the center device automatically responds to this and the display data is subsequently transmitted from the center device, the display data is received and sequentially stored in the memory, and the stored display data is read from the memory by a predetermined operation. It is issued and displayed on the display.

[0003]

The above-mentioned conventional telephone device with a data communication function confirms the data previously received from the center device by displaying it on the display unit, and if the confirmed data is not erased thereafter. The newly received data is not stored in the memory, or the previously received data is overwritten with the new data. That is, if the user forgets to delete the data after confirming the data, there is a problem that the subsequent data cannot be downloaded or the new data is rewritten before the previous data is confirmed.

[0004]

In order to solve such a problem , the present invention displays on a display device based on a confirmation operation.

It is re-IC. Further, E is a battery for holding the data stored in the SRAM at the time of power failure, SP is a speaker, HS is a handset, L is a telephone line, and SW is a telephone line L on either the communication unit 11 side or the data communication unit 12 side. It is a switch to switch to.

Further, FIG. 3 is an explanatory view for schematically explaining the memory configuration in the memory card 7 for storing the display data coming from the center device. In FIG.
Is a storage area for display data, 101 is a storage area for the date and time when the display data is stored, 102 is a storage area for a confirmation flag described later, and A1 to A45 are addresses. The general operation of the telephone device with a data communication function will be described with reference to FIGS. 1 and 3. In order to receive the display data indicating various information stored in the center device, the CPU 1 in the telephone device with the data communication function reads the time from the clock unit 5, and when this matches the preset time, the CPU 1 automatically While capturing the telephone line L,
Dial the center device. When the center device automatically responds to this, the switch SW is set to the communication unit 1.
When the display data is transmitted from the center device after switching to the 2 side, the display data is received via the modem in the communication unit 12. Then, when the predetermined memory area 100 in the memory card 7 is empty, the received data is immediately stored in the memory area 100 via the memory card I / F unit 6 and the predetermined memory area 100 is in the empty state. If not, it is determined whether or not the confirmation flag is set by referring to the confirmation flag area 102 corresponding to this memory area 100. If the confirmation flag is set, display data is displayed in the corresponding memory area 100. Store. When the display data is stored, the date / time data at that time is stored in the date / time data area 101, and the confirmation flag area 102 is also stored.
Reset the confirmation flag of. After that, when the operator operates the key unit 10 for a predetermined time, the CPU 1 detects this and reads the display data stored in the corresponding display data storage area 100 and sends it to the LCD controller 9a.
The confirmation flag in the confirmation flag area 102 corresponding to the memory area 100 in which the displayed data is stored is set while being displayed on the CD unit 9b. After that, the operator operates the key unit 10,
When the erasing operation is performed, the data being displayed on the display unit 9 is erased from the memory area 100.

Next, FIG. 2 is a CPU for performing the operation of the above embodiment.
It is a flowchart of 1. Detailed operation will be described with reference to FIG. In step 50, the date from the clock unit 5
The time information is read to determine whether or not a preset time has passed. If the set time is determined to be “Y”, the center device automatically transmits at step 51 and the center device at step 52. If you respond to this, step 5
At 3, the register N is set to 1. Then, the display data storage area corresponding to the value of the register N in the memory card 7, that is, N (N = N = N) indicated by the address A1 in this case.
1) Determining the empty state of the screen area (step 54),
If the area 100 has become empty due to the above-described erasing operation, the process proceeds to step 60 to receive the N screen data from the center device, and the received N screen data is indicated by the address A1 in step 61. While storing in the N screen data area 100,
The date / time data at this time is stored in the corresponding date / time area 101, and the corresponding confirmation flag is reset. After that, the routine proceeds to step 62, where it is judged whether or not the preset display data for all screens has been stored. If it is determined to be "N", the value of the register N is incremented by 1 in step 63, and the process proceeds to step 64 to determine whether the value of the register N is larger than 45 or not.

In the case of this embodiment, since the maximum number of areas for storing display data is 45, the value of the register N is incremented each time each screen data is stored and this value is larger than the maximum value 45. In some cases, the maximum number of areas is determined because no more screen data can be stored. If it is determined to be "N" in step 64, it means that there is still an area where the display data is stored. Therefore, the process returns to step 54 and the next screen data indicated by the value of the register N is stored. Should area 100
If the area 100 is empty, the next screen data is received from the center device and the received screen data is stored in the corresponding area 100. When the image data thus received is sequentially stored in the corresponding empty area 100, the preset number of screen data is all stored in the area 100, and the result of the judgment in step 62 is "Y", In this case, the telephone line L is opened in step 67, and the communication lamp (not shown) is blinked in step 68 to finish. In addition, as described later, the corresponding screen area 100
Is not empty and the confirmation flag is not set, the data cannot be stored in the screen area. Therefore, the preset determination of storing all screen data is determined as “N” in step 62. In this case, the value of the register N is incremented in step 63, and when this value exceeds the maximum screen data storage area number 45, it is determined to be “Y” in step 64, the process proceeds to step 65 and the telephone is called. The line L is opened and the communication lamp is blinked in step 66 to end the process.

Next, the N screen area 1 in the memory card 7
If 00 is not empty, it is determined as “N” in step 54, the process proceeds to step 55, and the data in this area 100 is confirmed, whereby the confirmation flag area 102 corresponding to this area 100 is confirmed. Judges whether the confirmation flag is set, is this set and confirmed? If it is determined to be “Y”, it means that new data can be overwritten in this data area 100, and thus the processing from step 60 onward is executed.
Also, has it been confirmed in step 55? Is determined to be "N", it means that the data cannot be stored, so that the value of the register N is incremented in step 56, and then it is determined in step 57 whether the value of the register N is larger than 45 or not. Then, when the value of the register N is smaller than 45, the process returns to step 54, and when the value of the register N is larger than 45 and it is determined to be "Y" in step 57, the telephone line L is opened in step 58. And then it ends.

The screen display data stored in the memory card 7 in this manner is displayed on the display unit 9 and the confirmation flag is set only by the confirmation operation by the operator, and is therefore referred to as confirmed data. As a result, the screen display data that arrives next time is rewritten, and as a result, the next data can be downloaded without any trouble. In addition, since unconfirmed data is stored as it is, it will not be deleted even if you forget to confirm it.

[0012]

As described above, according to the present invention, when the confirmation operation of the data stored in each area of the memory is performed, the confirmation flag corresponding to this area is set and the data from the center device is stored. When receiving, the received data is stored only in the area where the confirmation flag is set, so the data in the area corresponding to the set confirmation flag is reconfirmed data and is rewritten to the data that will arrive next time. As a result, the data can be downloaded next time without any trouble. Further, since the unconfirmed data is stored as it is, there is an effect that it is not erased even if the confirmation work is forgotten.
