In the present embodiment, the salesperson walks while holding the electronic notebook 11 with the data transmission card 5 attached, and inputs, for example, order data, that is, which customer has ordered which product and how many pieces. . When the data is accumulated, the data transmission card 5 is removed and placed on a telephone receiver of a public telephone or a customer's telephone as shown in FIG. 4 to transmit data as acoustic data.

The operation of the circuit will be described below with reference to FIG.
The electronic notebook 11 performs order data input processing in addition to basic processing such as calendar, schedule, telephone directory, business card management, memo, clock, and calculation. The program for basic processing is stored in the memory 44 in the electronic notebook 11. In the present embodiment, the order data input processing program is stored in the memory 49 of the data transmission card 5 and is read and executed via the memory card interface 45.
It may be stored in the memory 44 in the No. 1 unit.

The order data input to the electronic notebook 11 is stored in the memory 49 in the data transmission card 5. The data transmission card 5 is connected to the electronic notebook 11, and the electronic notebook 11
Is operating, the power of the memory 49 is the electronic notebook 11
Supplied from When the order entry data has been input and the data is to be transmitted, the data transmission card 5 is removed from the electronic notebook 11. The power supply of the memory 49 at this time and the other power supply in the data transmission card 5 at the time of data transmission are
It is supplied from the battery 48.

The control program of the data transmission card 5 is
In the present embodiment, it is stored in the memory 55 which cannot be rewritten via the memory card interface 45, but it may be stored in the memory 49.

When transmitting data, when the dial transmission key 2 is pressed after the data transmission card 5 is set in the handset 21 as shown in FIG. 4, the CPU 54 reads the telephone number data from the memory 49 and the DTMF (Dual (Dual)). To
The signal is sent to the ne Multi Frequency (multifrequency signal) modulation circuit 53. The passed telephone number data is modulated and sent out from the piezoelectric speaker 1 by the speaker driving circuit 51 as a push button dial signal. That is,
The dial transmission key 2 is a specific key for transmitting a push button dial signal. The DTMF modulation circuit 5
In No. 3, the pushed selection signal is sent out by two types of DTMFs, the low group and the high group, like the conventional push-phone. In this case, each time the dial transmission key 2 is pressed, the push button dial signal is repeatedly transmitted. In addition, if the dial transmission key 2 is pressed and the dial signal is transmitted, and then the dial transmission key 2 is pressed again within a fixed time,
The data transmission described below may be performed. Further, the data may be transmitted again by pressing the dial transmission key 2 within a fixed time after the data transmission.

Next, when the data transmission key 3 is pressed, the CPU
Reference numeral 54 reads the transmission data from the memory 49 and transfers it to the FSK modulation circuit 50. Then, the data is FSK-modulated, and is sent out from the piezoelectric speaker 1 by the speaker drive circuit 51 as modulated data of "1": 1270 Hz, "0": 1070 Hz, for example. Also in this case, the transmission data is repeatedly transmitted each time the data transmission key 3 is pressed, as in the above.

In FIG. 5, 42 is a keyboard,
Reference numeral 43 is a battery, and 46 is a display, both of which are provided on the electronic notebook 11 side. A sheet key 47 is provided on the data transmission card 5 side.

Next, a data transmission system using a data transmission card will be described. The system configuration is shown in FIG. 6, and the data transmission procedure is shown in FIG. Data is transmitted by the following procedure. The handset 21 (FIG. 4) of the telephone set 55 is turned off to enable the call.

The speaker portion of the data transmission card 5 is fitted to the mouthpiece of the handset, and a dial signal is generated to call the reception center 57.

The earpiece is put on the mouthpiece of the handset, and it is confirmed that the workstation 59 of the reception center 57 controls the modem 58 to connect the line.

After confirming a voice message prompting transmission from the voice synthesizer 60 of the work station 59, the speaker portion of the data transmission card 5 is again aligned with the mouthpiece of the handset to transmit data.

The earpiece of the handset is placed on the ear and the voice message from the voice synthesizer 60 of the workstation 59 is checked to see if there is a data transmission error. If there is a transmission error, return to. If not, turn on the handset.

As described above, the data transmission card of this embodiment has the effect of being easy to carry. Further, since the circuit configuration is simple, it is cheaper than the wireless communication device.

Reference numeral 51 is a data collection device, and 56 is a telephone line.

[0025]

According to the present invention, by constructing the data transmission card and the data transmission system device as described above, it is possible to reduce the size and cost of a portable device such as an electronic notebook and a handy terminal. . Also, since this card uses a telephone line for data transmission, there is no limit to the usable area like wireless, and it can be transmitted from anywhere.
