DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic register that allows the type of display to be freely exchanged.

[Prior Art] An electronic cash register, which is installed in a general store and which registers sales data of sold products and performs payment processing for sales proceeds, is configured as shown in FIG. 5, for example. That is, a keyboard 2 is provided on the front of the housing 1 for inputting sales data such as the sales amount and number of items sold, and above the keyboard 2 is a printer that prints out the sales data on a receipt. mouth 3,
A display 4 for displaying sales data and the like is provided, and a drawer 5 for storing cash such as sales proceeds is provided below. Further, a card reader 6 is provided between the keyboard 2 and the drawer 5 to read information recorded on a credit card or the like.

In such an electronic cash register, sales data input from the keyboard 2 and card information read by the card reader 6 are displayed on the display 4. The display 4 also displays information such as the total amount and change.

[Problems to be Solved by the Invention] However, even with the electronic cash register configured as shown in FIG. 5, the following problems still exist. That is, in recent years, electronic cash registers have been used not only in general stores but also in various places such as restaurants, hotels, and theaters. Therefore, various information is input from the keyboard. As a result, the type and amount of information displayed on the display 4 vary. Furthermore, display formats also vary.

The type and display format of information to be displayed on the display 4 are set or changed by setting or changing the control program at the time of shipment from the factory or at the time of installation at a location specified by the user.

Therefore, the information requested by the user can be displayed in the display format requested by the user only by operating a software program without changing the hardware circuit.

However, if the user significantly increases the amount of information to be displayed or if the user requests a display that is easier to view, it is necessary to change the type of display. For example, it may be necessary to change an electric display using a dot display element or a segment display element to a CRT display, or conversely, to change from a CRT display to an electric display.

However, in order to change the type of display, it is necessary not only to replace the display main body, but also to change the drive circuit that drives the display. Therefore, apart from replacing the display unit installed outside the housing 1 at the time of factory shipment or installation at a designated location, replacing the drive circuit installed inside the housing 1 would be a very troublesome task. Become.

By providing multiple types of control circuits for display devices, the present invention allows the type of display device to be easily changed as needed, and the display device can be easily changed according to user requirements at the time of factory shipment, installation, or inspection/repair. The purpose is to provide an electronic cash register that allows the exchange of

[Operation] The electronic cash register configured in this manner is provided with a plurality of display control circuits to which different types of display devices can be connected. Therefore, when a new display is installed at the factory, or when the display is replaced at the request of a user, display information that specifies the type of the installed display is set in the display information memory. Then, during normal use of this electronic cash register, the display data will be correctly displayed on the attached display.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is an external view showing the electronic cash register of the embodiment. Note that FIG. 2 shows a case where an electronic display 14a composed of, for example, a dot display element is attached as a display.

A keyboard 12 is provided on the top surface of the housing 11 for inputting sales data such as the sales amount and number of items sold.
A receipt issuing port 13 for a printer that prints out sales data on receipts is provided above the keyboard 12, and a drawer 15 below stores cash such as sales proceeds.
is provided. Further, a card reader 16 is provided above the keyboard 12 to read information recorded on a credit card or the like. Furthermore, an electronic display 14a is attached to the top surface of the housing 11 to display sales data and the like.

FIG. 1 is a block diagram showing a schematic configuration of an electronic cash register. A CPU 17 that executes various calculation processes based on various information input from the keyboard 12 or card reader 16 is connected to a ROM 19 that stores a control program, a RAM 20 that stores various variable data such as sales data, etc. via a pass line 18. It controls a key input circuit 21 to which key signals are input from the keyboard 12, a printer control circuit 23 of a printer 22 which prints out sales data and the like on receipts and journals, a card reader control circuit 24 which controls the card reader 16, and the like.
