The cash transfer unit includes a storage unit and a registration-side cumulative processing unit that accumulates time information obtained from the storage contents of these storage units in the cashier memory. The money transfer unit displays the time of the clock circuit each time the calling key is operated. Call time storage means for storing, drawer closing time storage means for storing the time of the clock circuit each time the drawer is closed, and time obtained from the contents stored in these storage means. Information is obtained by a money transfer side cumulative processing means accumulating a cacheable memory.

According to the second aspect of the present invention, the product sales data input through the input device is stored in the item buffer memory, and the total amount for one customer is calculated and stored by the temporary tightening key operation. The product sales data for one customer and the total price stored in the item buffer memory in the registration unit are called by key operation, and the product sales data and the total price called by the printer in response to the closing key operation are sent to the receipt. In a product sales data processing device that prints and issues a receipt, displays the total amount on the display, and separates the money transfer unit that opens the drawer, a clock circuit that counts the current time and registration The temporary tightening time storage means for storing the time of the clock circuit every time the temporary tightening key is operated on the department side, and the money transfer side A waiting time calculation for calculating the waiting time of one customer from the calling time storage means for storing the time of the clock circuit each time the calling key is operated, and the stored contents of the temporary fastening time storage means and the stored contents of the calling time storage means. Means, and a waiting time management means for managing the waiting time calculated by this calculating means.

[Operation] In the invention of claim 1, when the cashier of the registration unit inputs the first product sales data of the customer through the input device, the time at that time is stored. After that, when the temporary tightening key is operated for registration of this customer, the time at that time is stored. Then, the input time of the first product sales data is subtracted from the temporary tightening key operation time to calculate the processing time in the registration unit for one customer by the cashier, and the processing time in this registration unit is accumulated in the cashier memory. It

On the other hand, when the cashier of the money transfer unit operates the call key, the time at that time is stored and the product sales data of a customer and the total price thereof are called. Next, when the tightening key is operated by a key, a receipt is issued and the drawer is opened, so that money is exchanged with the customer. After that, when the drawer is closed, the time at that time is stored. Then, the call key operation time is subtracted from the drawer closing time to calculate the processing time in the money transfer unit for one customer by the cashier, and the processing time in the money transfer unit is accumulated in the cashier memory.

According to the second aspect of the present invention, when the cashier of the registration unit operates the temporary fastening key for registration of a customer, the time at that time is stored. After that, when the cashier of the money transfer unit operates the calling key, the merchandise sales data of the customer and the total price thereof are called and the time at that time is stored.
