Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sales data processing device equipped with a communication source constituting a POS system, etc., and in particular to a sales data processing device that performs registration processing based on input sales data. , relates to a sales data processing device such as an electronic cash register that transmits and receives data to and from other data processing devices according to a digital transmission method.

[Prior Art] Conventionally, in a POS system, multiple electronic cash registers (ECRs), host computers, etc. are connected to each other via dedicated lines within the premises, and data regarding products is sent and received using a digital transmission method. That's what I do.

In other words, since conventional POS systems are configured to digitally communicate only product-related data (product code, product name, sales data, etc.), for example, when cashiers communicate with each other, each ECR This was done using intercoms and other communication equipment provided in the area.

[Problem to be solved by the invention] In this method of directly communicating between cashiers using telephones, a line (analog transmission line) dedicated to telephone calls is required.
In addition, if a call is received from the recipient during registration, there is a problem in that the registration must be interrupted and a response must be made.

An object of the present invention is to eliminate the need for a dedicated line for telephone calls, and to make it possible to output voice data transmitted from the other party at any time.

[Means to solve the problem] The means of this invention are as follows.

The audio converting means 1 (see the functional block diagram in FIG. 1; the same applies hereinafter) is an analog/audio converter that encodes an audio signal input from a microphone or the like and converts it into digital audio data.
A digital conversion circuit performs digital conversion according to, for example, a baseband signal system.

The transmission control means 2 transmits the audio data converted by the audio conversion means 1 to a prespecified transmission destination when transmitting it to another data processing device.

The audio storage means 3 is a RAM or the like that stores and holds audio data digitally transmitted from another data processing device when the audio data is received.

The output specifying means 4 is a key input section or the like that specifies the output of the audio data stored in the audio storage means 3.

The audio output means 5 is a digital/digital converter that converts the audio data read from the audio storage means 3 into an audio signal and outputs the audio signal when output of audio data is designated by the output designation means 4.
These include analog conversion circuits and speakers.

[Made by J The operation of the means of this invention is as follows.

First, when transmitting an arbitrary message or the like to another data processing device by voice, the transmission destination is specified in advance and the content indicating the message is uttered into a microphone.

Then, the input audio signal is digitally converted by the audio conversion means 1, and the audio data thus converted is transmitted to a transmission destination specified in advance by the transmission control means 2.

On the other hand, when audio data transmitted from another data processing device as described above is received, the audio data is stored and held in the audio storage means 3.

Therefore, when the output specifying means 4 specifies the output of audio data at any time, for example, when the registration process for one transaction is completed in ECH, the audio output means 5 outputs the audio data read out from the audio storage means 3. Converts data into audio signals and outputs them.

Therefore, there is no need for a dedicated line for one call, and the voice data transmitted from the other party can be output as voice at any time.

[Example] Hereinafter, one embodiment will be described with reference to FIGS. 2 to 8.

FIG. 2 is a block circuit diagram showing an ECR as a POS terminal, and this ECR is connected to other ECRs via an inline IN.

The CPU II controls various operations of this ECR according to the microprogram stored in the ROM 12, and performs registration processing based on input sales data, and also registers other ECRs according to the digital transmission method.
Performs data transmission and reception processing between the CPU II
takes in the sales data by product inputted from the key personnel section 13 via the input control section 14 and registers it in the sales data memory 15-1 in the RAM 1S, but in this case, the ECR of the function
In order to make inquiries about product unit prices and the like to the master side ECR, data is sent and received to and from the master side ECR via the transmission section 16.

Note that the CPU II sends sales data and the like to the display control section 17 and the print control section 18, displays them on the display section 19, causes them to be printed out from the printing section 20, and further controls the opening operation of the drawer 21.

Further, the ECR of the fifth embodiment is provided with a microphone 22 and a speaker 23.
The audio signal input from the A/D (analog/digital) converter 24 is sent to the A/D (analog/digital) converter 24 . This A/D converter 24 encodes the input audio signal and converts it into digital audio data.The audio data thus converted is taken into the CPU II and then stored in the audio data memory 15 in the RAM 15. -2. The audio data stored in the audio data memory 15-2 is arbitrarily read out under the control of the CPU II, sent to the transmission section 16, and sent to the ECR, which is a pre-specified transmission destination. In this case, as in normal data transmission, the voice data is transmitted along with the own machine name set in the RAM 15 to indicate the transmission source. On the other hand, when audio data transmitted from another ECR is received, the audio data is taken into the CPU II via the transmission section 16.

The audio data is stored in the audio data memory 15-2. In this case, when audio data is received from another ECR, the lamp LP on the display section 19 is lit to notify that fact. The received data (audio data) stored in the audio data memory 15-2 is arbitrarily read out under the control of the CPU II and sent to the D/A (digital/analog) converter 25. After being converted into the original audio signal by the A converter 25, the audio signal is output from the speaker 23.

In this embodiment, the audio data memory 15-2 is constituted by a large-capacity memory capable of storing three types of audio data each having a maximum time length of about 6 seconds.

In addition, the keyboard of the key input unit 13 includes 1 normally provided numeric keypad AK, various function keys B
K, In addition to the mode switch MS, a recording key CK is used to store input audio in the audio data memory 15-2 and digitally record it, and a transmission key DK is used to arbitrarily read out the recorded audio data and send it to the transmission destination. , Output key-E for arbitrarily outputting audio data transmitted from other ECRs
K is provided. In addition, the mode switch MS has rp (setting) and rREG (registration) corresponding to its switching position.
", rOFF (power off)", "X (inspection)", rz(
It is a control fist lock that switches each mode of ``Payment''.

Next, the operation of this embodiment will be explained with reference to FIGS. 3 to 8.

First, when recording arbitrary audio, as shown in FIG. 7, the user operates the recording key CK, and then operates the numeric keypad AK to indicate the storage position n of the recorded content to enter the memory.

Then, the CPU II executes the operation according to the flowchart in FIG.

That is, when the CPU II enters this flow, it first sets the recordable state (step AI).

In this state, when recording contents (information to be transmitted to other E(l)) are generated toward the microphone 22, the audio signal input from the microphone 22 is transmitted to the A/D
The audio data sent to the conversion unit 24 and digitally converted by the A/D conversion unit 24 is taken into the CPU II and then stored in the audio data memory 15-2 (step A2). The audio data is sequentially stored from the beginning of the corresponding specified area between the memories. At this time, in the first step A3, it is checked whether or not there is an empty area in the specified area. If the designated area becomes full during recording, the process proceeds to step A6, where a message prompting retry is displayed and output. That is, in this embodiment, the audio data memory 15-2 is capable of storing three types of audio data of up to about 6 seconds.
If the recorded content exceeds a predetermined maximum time length, a message is displayed to prompt re-recording.

However, if the memory for l recordings is not full, the process proceeds to step A4, based on whether or not the recording end key (not shown) is operated. It is checked whether or not the audio input for the recording has been completed, and the process returns to step AI and the above-described operations are repeated until the input is completed. Here, when the above-mentioned recording end key is operated, the process proceeds to step A5, and the end code is reset to the specified area in the audio data memory 15-2.

When the voice input for one recording is completed in this way, the next recording is started according to the key operation procedure shown in FIG. 2 can store up to three types of audio data.

Next, when transmitting the audio data stored in the audio data memory 15-2 as described above to an arbitrary ECR, the transmission key DK is operated.

Then, the CPU II executes the operation according to the flowchart shown in FIG.

First, in order to specify the audio data to be transmitted, input the memory location of the audio data memory 15-2 in which the audio data is stored using the key input section 13, and input the terminal location indicating the transmission destination using the key input. A numeric value is input from the section 13 (step B1).

Then, the CPU II searches the audio data memory 15-2 for the corresponding area based on the input memory error (Step B2). If the corresponding area is not found (NO in Step B3), the CPU II sets the transmission key DK as a non-function. The operation is invalidated, but if there is a corresponding area (YES in step B3), audio data is read from that area and given to the transmission section 16, and the audio data is transmitted to all other ECRs along with the input terminal collapse. (step B4), and then the next step B5
Return to step B4 and repeat the transmission operation until it is detected that the end code has been read from the corresponding area.
Here, if the end code is detected, the process proceeds to step B6, where the reception status of the other party is confirmed, and if the reception is not normally received, it is processed as a non-function. In this case, it is sufficient to operate the transmission key DK again.

Figure 8 shows the transmission format when transmitting audio data. This format consists of a start code (S), the destination terminal code, audio specification data indicating that the transmitted data is audio data, audio data (digital data)
, and an end code (E).

On the other hand, the operation when audio data is transmitted from another ECR will be explained with reference to FIG.

FIG. 5 is a flowchart showing the audio data reception process executed at regular intervals.

First, when receiving voice data from another ECR in a reception waiting state (step C1), it checks whether the data is addressed to itself based on the terminal failure in the received data, and
If the data is for you.

The received data is stored in the audio data memory 15-2 (step C3), and if the recorded data is still stored in the audio data memory 15-2, the recorded data is deleted and then the received data is stored. Then, in the next step C4, if it is detected that there is no empty area in the audio data memory 5-2, the non-functions are requested, but if there is an empty area, it is determined whether the received data is an end code or not. Check (step C5). If it is not the end code, return to step CI, and from now on, on the condition that there is an empty area in the audio data memory 15-2, the data is stored in the audio data memory 15-2 until the end code is received. The receiving process of sequentially storing the received data is repeated, and when the end code is detected, the process proceeds to the next step C6, and the lamp LP on the display section 19 is turned on to indicate that the audio data has been received. Then, a response is sent to the transmission destination to the effect that the audio data has been successfully received (step C7).

In this way, when audio data is normally received from another ECR, the lamp LP is lit, so the ``Kya'' message is displayed.

Sha can know that.

Here, if the cashier is currently registering, the cashier operates the exit key EK after completing the registration.

Then, the CPU II executes the operation according to the flowchart shown in FIG.

First, the received data (audio data) is searched from the audio data memory 15-2 (step DI), and then this received data is read from the audio data memory 15-2 and given to the D/A converter 25 (step D2). As a result, the D/A converter 25 converts the received data into the original audio signal and supplies it to the speaker 23, so that the received data is output as audio from the speaker 23. When it is detected in the next step D3 that there is received data in the audio data memory 15-2, it is checked whether the end code has been read out from the audio data memory 15-2 (step D4). , here, if it is not an end code, the process returns to step D2, and the received data is subsequently output as voice until an end code is detected.

Furthermore, if two or more pieces of received data are stored in the audio data memory 15-2, the output key DK may be operated again.

Incidentally, when the received data is output as audio, although not shown in the flowchart of FIG. 6, the destination terminal information is displayed on the display section 19.

[Effects of the Invention] This invention is advantageous in terms of cost because it eliminates the need for a line dedicated to telephone calls, and the voice data transmitted from the other party can be generated and output at any time.
For example, even if audio data is transmitted during registration in ECR, the registration can be checked without interrupting the registration and after the registration is completed.
