Description

[Detailed description of the invention]

[Industrial Application Field 1] This invention relates to a sales data processing device such as an electronic cash register equipped with six customer displays and an operator display. [Prior Art] Generally, an electronic cash register (ECR) has the following features:
In addition to the operator's display, a customer's display is provided, and the results of registering sales data are displayed on the operator's display and the customer's display, respectively. Here, FIG. 8 shows a typical ECR, and the front and rear surfaces of this ECR main body include a front display (operator's display) 1 and a rear display (customer's display) composed of, for example, a fluorescent display tube. A display device) 2 is provided. In addition, Figure 9 shows a high-end model (POS terminal type) EC
A large operator display s3 consisting of a CRT display or the like is provided on the front of the ECR main body, and a customer display 4 consisting of a fluorescent display tube is provided on the rear. There is. [Invention tries to solve! ! By the way, in recent years, the functionality of ECR has been improved more and more, and the problem has become how much information can be displayed and output on one screen. For example, when setting various data in the FLU memory, a large number of data such as product name, product unit price, product code, and other data are input as preset data for one product, as shown in Figure 8. In a typical ECR, the operator display ! It was not possible to display and output all the preset data for a product at once, and there were serious problems such as setting errors. In addition, as shown in FIG. 9, when a large display device such as a CRT display device is used as the operator display device 3, the cost increases, making it unsuitable for low-priced ECRs provided for retail stores. Met. An object of the present invention is to enable a one-customer display to be used as part of an operator display, if necessary. [Means for Solving the Problems J The means of this invention are as follows. The customer display 11 (see the functional block diagram in FIG. 1; the same applies hereinafter) is rotatably attached to the main body of the device, and by rotating the customer display 11, for example, the display surface can be changed. !
It can be oriented from the back of the main unit to the front, or from the front to the back. The operator display 12 is attached to the front side of the main body of the apparatus, that is, on the operator side, and is a display with approximately two display lines. The detection means 13 detects by rotating the customer display 11 whether the display surface is facing the customer gI (for example, the rear side of the device body) or the operator side (for example, the front side of the device body). When the detection means 13 detects that the display surface of the customer display 11 is facing the customer, the display control means 14 of No. 1 displays the registration results of sales data on the customer display 11 and the operator display. The second display control means 15 causes the customer display 11 to output a display when the detection means 13 detects that the display surface of the customer display 11 is facing the operator. The display is controlled as part of the operator display 12.

[For use]

The operation of the means of this invention is as follows. When setting various data in the FLU memory in the ECR, the operator rotates the customer display 11 so that the display surface faces the operator. Then, the detection means 13 detects the direction of the customer display 11 by rotating it, but in this case, since the display surface of the customer display 11 is facing the operator side, the detection means 13 detects the state. The second display control means 15 controls the display of the customer display 11 as part of the operator display 12. For example, the customer display 11 and the operator display 1
2 each has a two-line configuration.1. Also, assuming that the preset data for 1 product is composed of product name, unit price, product code, and department code, 1 customer display 1
1, the product name is displayed on the first line, the unit price is displayed on the second line, the product code is displayed on the first line of the operator display 12, and the department code is displayed on the second line. In other words, the preset data for the product is stored on the operator display 12 and one customer display.
By using , all the data can be displayed and output at once. Note that when the display surface of the first customer display 11 is directed toward the customer, the detection means 13 detects the orientation, so the first display control means 14 sends the registration results of sales data to the customer display 11 and the first display control means 14, respectively. Display output is made on the operator display 12. In other words, when the display surface of the 1-customer display 11 is turned toward the customer,
The display contents of the customer display 11 will be the same as usual. Therefore, the single customer display can be used as part of the operator display if necessary. [Example J Hereinafter, an example will be described with reference to FIGS. 2 to 7. FIG. 2 is an external perspective view of the ECR, in which the ECR main body 21 is provided with an operator display 231 and a customer display 24 in addition to a keyboard 22. The operator display 23 is fixed to the top surface of the ECR main body 21 via a mounting shaft 25, and its display surface is
It faces the front side of the main body 21 (operator gI). The operator display 23 is a light-emitting display using a fluorescent display tube, and has a one-line upper display section 23a and a lower display section 23b. The customer display 24 is rotatably attached to the upper surface of the ECR main body 21 via a mounting shaft 26, and is located near above the operator display s23. The display surface of the 1-passenger display 24 is usually on the rear side of the ECR main body 21 (
However, when the 1-customer display 24 is rotated 1000 times as shown in FIG.
It is positioned in the same direction as the Similarly to the operator display 23, the customer display 24 is a light-emitting display using a fluorescent display tube, and has an upper display section 24a and a lower display section 24b. FIG. 4 is a block diagram showing the basic configuration of the ECR. It controls various operations of this ECR according to the internal clock program of the CPU 31.
A sales data registration process is performed in which the sales data taken in through 4 is added up to the sales total in the RAM 35, and the registration results are given to the operator display 23 and the customer display 24 for display output. Here, the operator display 23 includes an upper display section 23a.
, the display controller 23 corresponds to the lower display section 23b.
c, 23d, and the customer display 24 also has an upper display section 24a and a lower display section. Dedicated display controller 24C12 corresponding to 24b
4d is provided. The RAM 35 is a well-known A configuration including a FLU memory, a department memory, etc., and a totalizer for each type of sales. The detection circuit 36 detects the rotation of the customer display 24 and the orientation of the customer display 24 that has changed due to the rotation, and the detection results are taken into the CPU 31. In this case, the CPU 31 checks whether the display surface of the customer display 24 has turned from the customer side to the operator side, or conversely from the operator side to the customer side, based on the detection result from the detection circuit 36. Ayuka is set in the flag register FR in the CPU 31. Here, when the display surface of the first customer display 24 is facing the operator side, the CPU 31 performs display control to use the customer display 24 as a part of the operator display 23. The CPU 31 supplies sales data and the like to the printing controller 37, causes the receipt/journal printer 3B to print out the data, gives an alarm command to the input controller 34, causes the buzzer 39 to generate an alarm sound, and also outputs the sales data from the drawer driver. A drawer drive signal is applied to 40 to control the opening operation of the drawer. The CPU 31 also takes in the date and time data obtained by the clock circuit 41 and provides it to the printing controller 37 as print data. FIG. 5 is a configuration diagram of the detection circuit 36. This detection circuit 3
6 are provided with rising edge trigger type delay type flip-flops (edge trigger type 1l-FF) 51 and 52. The detection circuit 36 includes a customer display 2.
4 rotation signals are input. This rotation signal is waveform-shaped by a Schmitt inverter 53 for chattering prevention, and is directly sent to an edge-trigger type D-FF 51.
The edge trigger type D-FF 52 is provided with a clock input terminal CK via an inverter 54. Edge-trigger type D-FF51.52 has a VCC level signal input to its D input terminal, and its Q output changes according to the signal input to its clock terminal CK within a certain period of time. .52
Each Q output is taken into the CPU 31 via the OR gate 55 as an interwoven signal iRQ. In addition, the Q output of the edge trigger WD-FF51 is sent to the CPU 31 via the three-state buffer 56 as the rotational direction detection signal DI.
be taken in as. In addition, edge trigger type D-FF
51 and 52, the clear command DO from the CPU 31 is sent to the clear terminal CL via the three-state buffer 57.
It is reset by inputting. Note that the output of the three-state buffers 56 and 57 is controlled according to select signals CE+ and CH2 from the CPU 31. Next, the operation of this embodiment will be explained. When the first customer display 24 is now rotated, the rotation signal is input to the detection circuit 36. in this case. Depending on whether the customer display 24 is rotated from the customer side to the operator side or from the operator side to the customer side, the Q output of one of the edge trigger type D-FFs 51 and 52 becomes a VCC level signal. Change. As a result, the interlaced signal iRQ is output from the OR gate 55 and taken into the CPU 31. Then, the CPU 31 executes interrupt processing according to the flowchart in FIG. First, the CPU 31 outputs a selection signal CEI to the detection circuit 36 and applies it to the three-state buffer 56. In response, the CPU 31 takes in the rotation direction detection signal D1 output from the three-state buffer 56, and displays the customer display 2.
It is checked whether the display screen 4 is facing the operator side (step Al), if the display screen 24 has been turned from the customer side to the operator side by rotation of the first customer display 24. The Q output of the edge trigger type D-FF 51 becomes the VCC level, and the rotational direction detection signal DI from the three-state buffer 56 becomes the VCC level. When this is detected in step AI, the process proceeds to step A2, and the flag register FR in the CPU 31 is Set the customer display flag to . Therefore, the customer display flag is turned on when the customer display 24 is rotated from the customer side to the operator side. Then, the CPU 31 gives a clear command D and a select signal CE2 to the detection circuit 36, and
The FFs 51 and 52 are reset to cancel the 1st interrupt (step A3). On the other hand, when it is detected in step A1 that the display surface of the customer display 24 has turned from the customer side to the operator side, the ON/OFF state of the 1st customer display flag is checked (step A4), and as a result, the 1st customer display flag is checked. If the display flag is turned on, the flag is turned off (step A5) and the display for one customer s2 is
Clear the display contents of 4 (step A6), and 1
The interrupt is canceled (step A3). If the customer display flag is turned off when the customer display 24 is rotated from the operator side to the customer side, the interrupt is canceled as is (step A3). . FIG. 7 is a flowchart showing display processing. First, when the CPU 31 enters this display process, it displays the customer display 24 based on the customer display flag in the flag register FR.
A check is made as to whether the camera is facing the customer or the operator (step Bl). Now, if the customer display flag is on, that is, the display surface of the customer display 24 is facing the operator, display control is performed to use the customer display 24 as part of the operator display 23 ( Steps B2 to B8), and if the display surface of the customer display 24 is facing the customer, the customer display 24
4 is used for customers as usual (steps B9 to 813). Now, the display operation when the display surface of the customer display 24 faces the operator side as shown in FIG. 3 will be described. Here, it is assumed that the product name, unit price, product code, and department code are set for each product in the PLU memory in the RAM 35. In this case, when various preset data (product name, unit price, product code, department code) are sequentially input for each product, the CPU 31 sets the input preset data in the FLU memory in the RAM 35 and sets the preset data. The data is displayed on the operator display 237 and the customer display 24. That is, if the preset data is a product name (YES in step B2), the CPU 31 causes the product name to be displayed on the upper display section 24a of the customer display 24 (step B3).
, if it is a unit price (YES in step B4), the unit price is displayed on the lower display section 24b of the customer display 24 (step B5), and if the preset data is a product code (YES in step B6), Operator display 2
Display the product code on the upper display section 23a of 3 (step B7), and if it is the department code (No in step B6)
, the department code is displayed on the lower display section 23b of the operator display 23 (step B8). In this way, when setting data to FLU memory, the third
As shown in the figure, precent data for one product can be displayed at one time by using the operator display 23 and one customer display 24. When some of the display devices 24 for 1 customer are facing the customer side, display control similar to 1 normal is performed. In this case, the CPU 31 performs registration processing based on the input sales data, and then displays the registration results on the customer display 24.
Display is output on the operator display 23. That is, when the CPU 31 displays the registration results on the customer display 24 and the operator display 23, if the data is a product name (YES in step B9), the CPU 31 displays the registration results on the operator display 23 and the customer display 24. Upper display section 23a, 24
a to display the product name (Steps B10 and B11), and if it is the sales amount (No in Step B9), the lower display section 23b of the operator display 231 and the customer display 24;
24b to display the sales amount (steps B12, B1
3). When the customer display 24 faces the customer in this way, the same data is displayed on the operator display 231 as usual.
Each is displayed on the customer display M24. Note that the configuration of the detection circuit 36 is not limited to the above embodiment,
A switch may be provided that is turned on/off by rotating the customer display 24, and the switch may be turned on while the display surface of the customer display 24 is facing the operator. [Effects of the Invention] This invention allows the customer display to be used as part of the operator display if necessary, so that the operator display can be preset for one product without having to use a large screen. All data can be displayed and output at once.
