The unit price data ``150 yen'' is set for the preset key ``10'', the unit price data 130 yen'' is set for the preset key ``11,'' and the unit price data 1225 yen is set for the preset key ``12''.

The measurement unit prices are set for the preset keys "9" to "12" above.

In other words, the preset keys "9" to "12" are set as the metering unit price preset keys.

Therefore, the department, amount and unit price preset by the preset key 8 are written into the preset content storage 33 as shown in FIG.

(m) "Registration" operation using register mode Turn the main switch 5 to "register" and set the mode switching key 9f to register mode.

In this state, the customer enters the price of the purchased product using the number keys 7, and operates the corresponding department preset keys "1" to "4".

In this case, when the price of the product is the same as the preset amount, preset keys "5" to "8" are operated.

For example, if the price of the product is 1,000 yen, preset key "5" is operated.

This registration operation is performed for each product, and for each product, the department code is displayed on the unit price display 11, and the price is displayed on the price display 1.
Displayed as 2.

Each time the registration data for one customer is input, it is added to the subtotal storage unit 32 of the memory 25 and printed out by the printer 42 as a receipt and a journal.

When the subtotal key 9h is operated in this registration process, the total data previously registered for one customer, that is, the contents of the subtotal memory 32, is called up and displayed on the price display 12, and printed on the printer 42. be outed.

In this state, when data on the amount received from the customer is entered using the number keys 7 and the deposit/total key 91 is operated, change calculation is performed, and the change data is displayed on the price display 12 and printed out on the printer 42. be done.

OV) "Registration" work in the weighing mode In this work, when the weighing unit price preset keys "91 to "12" of the preset keys 8 are operated, the amount in the preset content memory 33 corresponding to the operated weighing unit price preset key is recorded. Alternatively, the measured unit price is read from the unit price setting area 33b into the unit price storage 28 in the same memory 25.

Note that the measurement unit price data can also be input by operating the number keys 7.

In this business, if the unit price of the object to be measured is, for example, 1000 yen, the specific key operations are as follows.

First, operate the measurement unit price preset key "9".

Then, the measured unit price [0
00 yen" is written and displayed on the unit price display 11.

In this state, the receiver places the object to be weighed on the tray 2.

Is the weight of the object to be measured now 200? If so, the weight data is taken into the weight memory 26 and displayed on the weight display 10.

However, the unit price data "1000 yen" and the weight data "20
The price data "2,000 yen" is calculated from "0v", and the price data is taken into the price memory 29 and displayed on the price display 12.

In this state, when a department key (preset keys "l" to "4") corresponding to the object to be weighed is operated, price data is added to the totalizer 34 corresponding to the operated department key.

In this way, number key 7, preset key q, number key 7
By operating in combination with the same P preset key 8 as described above, the department, amount, and unit price can be set for a plurality of recent keys.

In particular, to set the weighing unit price, press the numeric key 10'', the preset key, and the numeric key ``unit price - reset key'' to preset the metric unit price data in the unit price or amount setting area 33b of the preset content memory 33. be able to.
