The automatic rotation type display device according to the present invention provides a rotation instruction immediately or after a predetermined delay time, or a rotation instruction based on an operation of the operator, by a signal applied to the rotation mechanism 14, for example, a signal associated with the pressing of the total key at the time of settlement. In response to the signal, the display unit 10 fixed to the other end of the rotary shaft 12 is rotated in either a left or right predetermined direction.

In this case, the angle of the direction change, the stop position and the like can be appropriately achieved by adjusting the rotating mechanism 14. Further, the returning motion from the once rotated position to the original position can be performed by the reverse operation of the rotating mechanism, and also the compressive force or the pulling force of the elastic body can be used.

It should be noted that the original position can be automatically returned after a time corresponding to the estimated time required for display confirmation. Further, it can be configured to be restored by an operator's forced return signal, a signal generated by an operation indicating the end of the settlement process, or the like.

When such an automatic rotation type display device is applied to an automatic settlement device such as a POS terminal, the display unit 10 has a first orientation on the operator side and a second orientation on the customer side.
The rotation angle is set so that it becomes the direction of.

In an automatic settlement device such as a POS terminal equipped with an automatic rotation type display device, an operator and a customer can confirm the same display by a single display device. Since a single display device is sufficient, it is possible to reduce the external size of the device and reduce the cost.

FIG. 5 is a plan view showing an arrangement example of POS terminals using the automatic rotation type display device according to the present invention. The position where the operator O stands is constant because it is the direction in which the keyboard can be easily operated, but the position of the customer C depends on the layout of the store or the like, and the side (C1) or front (C) of the operator.
It may change to 2).

Due to the layout around the POS terminal, the required rotation angle is 90 degrees toward the customer C1.
Different from around 180 degrees toward customer C2. The elements or configurations of the rotation mechanism 14 can be appropriately combined and used according to the required rotation angle.

FIG. 6 is a flow chart showing the relationship between the operating state of the POS terminal and the rotating state of the display section using the automatic rotation type display device according to the present invention.

After the end of the previous processing, the display section faces the operator. When the settlement of the transaction contents is entered by pressing the total key on the keyboard (step S1), the total amount is displayed (step S2), and the operator confirms this amount (step S3).

After a lapse of a predetermined time from the display of the total amount of money or in response to the operation of the rotation instruction key by the operator, the display unit is rotated to a direction in which the customer can easily see it (step S4). The customer confirms the displayed amount on the display unit (step S5)
Payment is made (step S6).

The operator receives payment of the required amount and inputs the amount from the keyboard (step S7). In response to this input, the display unit rotates toward the operator (step S8). Since the deposit amount and the change amount are displayed on the display unit (step S9), the operator confirms these amounts (step S10).

After a lapse of a predetermined time after the deposit amount and the change amount are displayed, or in response to the operation of the rotation instruction key by the operator, the display unit is rotated to a direction that is easy for the customer to see (step S11). The customer confirms the displayed amount on the display unit (step S12) and receives the change amount and the receipt (step S13).

Then, after a lapse of a predetermined time, the display unit is rotated and returned to the operator side (step S14), and the next transaction is continued.
