[Problem that the invention seeks to solve]

Since conventional POS terminals are configured with 1 or more units, an I10 device such as a floppy disk device is required to transfer the program for operating the POS terminal to the main memory, which increases the cost and size. It was a huge burden on the front. Furthermore, since it takes time to transfer the program from the I10 device, there is a problem in that it takes a long time to start up the terminal.

This invention was made to solve the above-mentioned problems, and it provides a small, low-cost product information register that can execute programs without using an I10 device such as a floppy disk, and also reduces the register start-up time. The purpose is to shorten the

[Means for Solving the Problems] The POS terminal according to the present invention can execute the program by connecting a RAM card on which a program has been recorded in advance to the product information register, and can perform product registration operations as a product information register. It was designed so that

[Effect]

The product information register in this invention uses a RAM card as the main memory of the CPU.
Enables you to run programs on the card.

Fig. 4 is an external view of the POS terminal, where (200) indicates when the operator operates the terminal keys (described later), for example, displays the result of inputting the product price or displays a message to the operator. The display includes a display section (IA) and a display cover (IB) that covers the display section (IA).

Any type of card other than a C-RAM card, such as an optical card or a magnetic card, can be used as long as it is writable, and the connection between the two connectors (6A) and (8A) is not limited to mechanical contact. Various types of coupling are possible, such as optical or magnetic coupling, and the type of coupling does not matter as long as information signals can be exchanged.

This can be done using various general detection means, such as checking the input/output bus signals of 0) on a program.

In the above embodiment, the IC-RAM card insertion/removal check and power supply control are performed by a program in the ROM, but it is also possible to perform all of the above control by hardware, and in that case, the above-mentioned ROM No program is required. It goes without saying that POS terminals are not only used for buying and selling products, but also for inventory management in warehouses and the like.

[Effects of the Invention] As described above, the present invention uses a removable RAM card as the main memory of the CPU, so that a program for executing product registration work, etc. of a product information terminal is recorded in advance on the RAM card. By simply connecting the RAM card to the product information terminal, the program will be started and product registration operations will be performed.
A program can be executed without using a device, a small, low-cost product information register can be provided, and the register start-up time can be shortened.
