In general, such electronic cash registers include a keyboard for inputting sales information, a device body that performs arithmetic processing, storage processing, etc. of the sales information input by the keyboard, and a device body that performs processing and storage processing of the sales information input by the keyboard, and a device body that stores the processing results of the device body. A printer to print and issue receipts, the price of the product, and
It is formed by a drawer or the like that stores change and the like.

These electronic cash registers are configured to perform various operations such as "registration,""inspection," and "payment" by operating control keys located on a part of the keyboard. be done.

Here, the above-mentioned "registration" means that after storing the price of the sold product in the RAM etc. inside the main body of the device, calculation processing of the total price etc. is performed, and the calculation result is printed on a printer and a receipt is issued. This is a job that involves
``Inspection'' refers to the task of printing out the total amount, total score, etc. cumulatively stored in RAM etc. through ``registration'' using a printer, and ``accounting'' mentioned above refers to cases such as at the end of work on -day, etc. Another task is to erase the contents of the total amount accumulated and stored in the RAM by "registration".

Further, such conventional electronic cash registers are usually located at checkout stations or the like located in a corner of a store. After selecting the desired product, the customer takes it to the checkout office.

At this time, the cashier registers all of the items in the electronic cash register. Furthermore, when the registration for this product is completed, the customer pays the amount charged to the cashier as the price for the product.

Therefore, all sales information of products sold in the store can be managed by the electronic cash register.

Problems to be Solved by the Invention However, since the payment for products sold in vending machines is done by the vending machine itself, the sales information must be registered in the electronic cash register installed at the payment office. This information is managed separately from the sales information provided.

For this reason, there may be a shortage of products in the vending machine or a shortage of change, which will hinder the sale of products.

In such a configuration, the electronic cash register is normally in a standby state in which a closing key (not shown) is pressed, as shown in FIG. When the closing key is pressed, it is determined whether the control key 3d is set to either inspection or payment.

If the control keys 3d and 3d are not set for either inspection or payment, the process moves to another routine.

Further, when the control key 3d is set to either inspection or payment, it is determined whether the mode changeover switch 3dj is set to the vending machine side.

If the mode selector switch 3d is not set on the vending machine side, the control key 3d.

After carrying out the normal inspection processing or payment processing set by , and printing the sales information using the printer 3c, the printer 3c returns to the closing key press standby state.

Further, when the mode selector switch 3d is set on the vending machine side, the contents of the RAM 10c in the vending machine 10 are read out by the sales information reading means, and the contents are read out from the RAM 2d in the electronic cash register. Write in the area.

Furthermore, after the contents of the remaining amount memory 2d and the contents of the change memory 2d are printed by the printer 3c, the state returns to the closing key press standby state.

That is, by setting the mode selector switch 3d to the vending machine side and setting the control key 3d to either inspection or payment (see Figure 7), and then pressing the close key (not shown). , the remaining amount of products and the remaining amount of change in the vending machine 10 are printed by the printer 3c.

In this way, the contents stored in the RAM 10c of the vending machine 10 are read out by the sales information reading means and then stored in the vending machine area of the RAM 2d of the electronic cash register. Therefore, sales information including sales from the vending machine 10 can be centrally managed using the electronic cash register.

On the other hand, the vending machine 10 is normally in a purchase operation standby state, as shown in FIG. Then, when some purchase operation is performed, it is determined whether the number of products stored in the aircraft is greater than or equal to a preset number.

When the number of products stored in the machine is less than a preset number, a warning signal is output by a warning signal output means, and after transmitting this to an electronic cash register, the machine returns to a purchase operation standby state. However, when the electronic cash register receives this warning signal, it generates an intermittent alarm sound using a built-in speaker as a warning means.
This notifies the cashier that the number of items is low.

Further, when the number of products stored in the machine is greater than or equal to a preset number, it is determined whether the amount of change stored in the machine is greater than or equal to a preset amount.

If the amount of change stored in the aircraft is less than the preset amount, the warning signal output means outputs a warning signal different from the one described above, and after transmitting this to the electronic cash register, the purchase operation is performed. Return to standby state. However, upon receiving this warning signal, the electronic cash register generates a continuous alarm sound through its built-in speaker or the like, thereby notifying the cashier that the amount of change remaining is low.

Further, if the amount of change stored in the aircraft is greater than or equal to a preset amount, the machine returns to the purchase operation standby state.

In addition, the above-mentioned alarm sound can be heard by the mode changeover switch 3d,
is set to the [Normal J side].

In this way, when either the product or the change stored inside the vending machine 10 becomes smaller than a preset value, a warning signal is output by the warning signal output means. Based on this warning signal, the electronic cash register generates an alarm sound through its built-in speaker to alert the cashier, thereby preventing the vending machine from running out of stock or running out of change.
You can reliably sell your products.
