Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to a control device for a vending machine, and particularly to a ten-key keyboard control device used for price setting and the like.

[Prior art and its problems]

A conventional control device of this type is shown in block diagram form in FIG.

In the figure, a vending control unit 1 of a vending machine controls the operation of an input coin sorter 2) a sellable display 8, a push button 4 for selecting a purchased product, and a product delivery mechanism 5 corresponding to the pressed button. It's all done. 6 is a numeric keypad for setting prices of the vending machine. When a push button on the numeric keypad 6 is pressed, input button information is sent to the sales control section 1 via the numeric keypad signal line 7. The sales control section 1 displays the numerical data of the pressed numeric keypad on the display on the tin keyboard 6 via the display signal line 8 in accordance with this input button information. Next, FIG. 4 shows an example of the appearance of a recent ten-key keyboard of this type. In the figure, 9 is a push button as a setting means, and 10 is a display for input data. As can be seen from Figure 4, in addition to price settings, recent vending machines have a number of features such as time settings to save energy, settings for the dispensing mechanism depending on the product being sold, and sales displays to obtain sales information. Functions are being added. Therefore, every time a function is added, the signal line 7.8
As the numbers increase, it is necessary to redesign the numeric keyboard 6 and the sales control section 1.

[Purpose of the invention]

In view of the above, the present invention is an automatic system that is capable of minimizing changes in the sales control section without increasing the number of signal lines between the numeric keypad and the sales control section, which are equipped with a means for setting the additional functions even when functions are added. The purpose is to provide a control device for vending machines.

[Summary of the Invention] This invention attempts to achieve the above object with the following configuration. In other words, it comprises at least a numeric keyboard having sales control means for controlling sales, setting means for setting prices, etc., and display means for displaying data input from the setting means via the sales control means. In a control device for a vending machine, the ten-key keyboard is capable of controlling input to a setting means and displaying data input from the setting means on a display means, and is capable of exchanging data with the sales control means. The filter is equipped with filter control means. In addition, a microcomputer (
It is preferable to use a CPU (hereinafter referred to as a CPU), and data transmission from the ten-key keyboard control means to the sales control means is preferably carried out by converting the data into codes according to a predetermined procedure. In other words, a dedicated CPU is installed in the conventional numeric keypad, and the signals from the numeric keypad to the sales control section are converted into codes according to a predetermined method and sent, and the development of the sales control section by adding functions can be done by simply changing the software. It was designed to be compatible with this.

[Embodiments of the invention]

The present invention will be explained below with reference to drawings showing embodiments. 1st
The figure is a block diagram of a control device for a vending machine according to the present invention. In the drawings, the same parts as in the conventional example are given the same reference numerals, and the explanation thereof will be omitted.

60 is a ten-key keyboard, and this ten-key keyboard controls reading input from the push button 9 and displaying the corresponding number on the display 10. It has PU70. This C! P
The U70 performs the above control at 71.72, and also inputs information on the pressed button to the sales control section 1 via the numeric keypad data signal line 7. Or, according to the contents of the input, for example, the CPU 70 receives price data etc. via the display data signal line 8, and the CPU 70 receives the price data etc. via the display data signal line 8.
2 on the display 9. Note that the data is transmitted from the 0PU 70 to the sales control section 1 by encoding the pressed button information in accordance with a predetermined procedure. Incidentally, FIG. 2 shows a flowchart of control using a ten-key keyboard in the case of price setting, which is an example of the control.

〔Effect of the invention〕

According to this invention, a CPU is mounted on the numeric keyboard section, and data is transmitted to the sales control section by encoding information on pressed buttons according to a predetermined procedure.For example, the button shown in FIG. In addition, even if column-specific sales buttons are added, it is only necessary to develop a new numeric keypad, and there is no need to change the hardware of the sales control section. In addition, since data is sent from the numeric keypad to the sales control department in code, the hardware and software of the sales control department can be changed in response to a customer request to set prices using barcodes, for example. You can get the effect that you don't need it.
