Description

The present invention has an auxiliary storage device such as a floppy disk drive that reads and writes the contents of a storage medium such as a floppy disk, and has a sales management function such as product management and customer management. Electronic register device.

2. Description of the Related Art Recent electronic cash register devices have been highly functionalized and have come to have functions such as merchandise management, customer management, and accounting work, in addition to simply summing up sales amounts. As a result of such progress, it has become necessary for the manufacturer and seller of electronic cash register devices to not only sell the electronic cash register devices, but also to have full control over the sellers and provide operation guidance and maintenance work.

The problem to be solved by the invention However, until now, the manufacturer and seller of the electronic cash register did not have control over the seller because they had to rely on the voluntary actions of the person who purchased the electronic cash register device, such as sending a questionnaire postcard. It was perfect.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems, and an object thereof is to provide an electronic cash register device in which a person who manufactures and sells an electronic cash register device can completely grasp the side that purchases the electronic cash register device.

Means for Solving the Problems In order to solve the above problems, an electronic register device according to a first aspect of the invention is an auxiliary storage device for reading the contents of a storage medium, and a main memory for storing the contents read by the auxiliary storage device. Device,
An electronic register device that includes an input device that inputs information from the outside and a control unit that has a central processing unit that performs various types of arithmetic processing, and that performs normal operation based on an instruction from the control unit. A storage medium configured as a set with an electronic register device, the contents of the storage medium storing a main program and a unique cipher preset for each electronic register device are read by the auxiliary storage device,
The encryption is stored in the main storage device, and after confirming that the content corresponding to the storage is input from the input device, the normal operation based on the main body program is performed.

The electronic register device according to the second aspect of the invention includes an auxiliary storage device for reading and rewriting the contents of a storage medium, a main storage device for storing the read contents of the auxiliary storage device, and an input for external information input. An electronic register device comprising a device and a control unit having a central processing unit for performing various kinds of arithmetic processing, and performing a normal operation based on an instruction from the control unit, which is stored in the storage medium when the power is turned on. After storing the cipher code unique to the electronic register device in the main memory device via the auxiliary memory device and confirming that the content corresponding to this memory has been input from the input device, the subsequent cipher input is unnecessary. The content of the encryption is rewritten by an auxiliary storage device.

Operation According to the above configuration, the cipher is stored in the auxiliary storage medium used in the auxiliary storage so that the cipher is read from the auxiliary storage to the main storage when the power is turned on, and the cipher is read from the key input device. Since the normal operation cannot be entered unless a corresponding key input is made, the manufacturer of the electronic register device manages the cipher for each electronic register device, and the electronic register device is purchased. When there is a cryptographic inquiry from, the information such as the name and address of the person who purchased the electronic register device can be grasped.

According to the second invention, in addition to the above operation, once the key input corresponding to the cipher is performed, the data is rewritten so that the cipher input is not required when the power is turned on thereafter. Can be extremely simple.

Example An example of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 1 is a circuit block diagram of an electronic register device according to an embodiment of the present invention.
Is an auxiliary storage device such as a floppy disk drive, 3 is a key input device including a keyboard, 4 is a system control unit including a central processing unit, and 5 is an auxiliary storage medium such as a floppy disk in which a cipher is stored. In the present embodiment, the auxiliary storage device 2 is a floppy disk drive, and the auxiliary storage medium 5 is a floppy disk (hereinafter referred to as "medium").

The electronic register device in the embodiment has a step of loading data from the medium 5 to the main storage device 1 when the power is turned on, and the cipher is stored in the medium 5 so that an accurate key input corresponding to the cipher can be performed. The feature is that the normal operation is performed only after being performed. The code is common to all electronic register devices, or changed for each lot,
Alternatively, the media 5 to be shipped together with the electronic register device is set so as to be different for each electronic register device. FIG. 2 is a flowchart showing the steps from power-on to normal operation. In this embodiment, once an accurate key input corresponding to encryption is made, it becomes unnecessary and the second and subsequent operations are performed. Easy going. FIG. 3 shows a map inside the medium 5, and FIGS. 4 and 5 show maps inside the main memory 1. 6, 7 are loaders as shown in FIG. 2, 8 and 9 are The encryption unit, 10 is the main program.

When the power is turned on, the central processing unit in the system control unit 4 is reset, and first the program in the boot ROM is executed. The Put ROM loads the 0 cylinder portions 6, 8 of the auxiliary storage medium 5 shown in FIG. 3 into the loader 7 and the encryption section 9 of the main storage device 1 shown in FIG. After loading, the program of the loader 7 is executed. First, the loader refers to the encryption unit 9. Next, the encryption unit 9 checks whether or not the data requires encryption input, and if it is not necessary, the main body program 10 is loaded, and thereafter, the main body program stored in the main storage device 1 is used to Information input from the input device 3 and, if necessary, the auxiliary storage medium 5
The data stored in (1) and (2) are processed based on an instruction from the system control unit 4, and the normal operations related to product management such as totalization of sales amount and issuance of receipts, customer management, and the like are performed.
The data that does not require encryption input is, for example, data of all 0, and this data is also used in this embodiment.
When the cipher input is required, it waits until the cipher is correctly input from the key input, and when the cipher is correctly input, the cipher unit 9 is cleared to zero and stored in the cipher unit 8. This makes it unnecessary to enter the code after the second time. Next, the main body program is loaded, and then the normal operation starts.

In the present embodiment, the encryption unit 9 stays in the main storage device 1 only when the loader is loaded, so the memory during normal operation is not reduced.

EFFECTS OF THE INVENTION As described above, according to the first and second aspects of the invention, the side that purchases the electronic cash register device cannot use the electronic cash register device unless the correct key input corresponding to the cipher is made. Inquiries about encryption become indispensable, and the side that manufactures and sells electronic register devices can grasp information such as the name and address of the side that purchased the electronic register device at the time of inquiry,
Since the subsequent operation guidance and maintenance work can be smoothly performed, it becomes possible to easily provide services to the purchaser.

Furthermore, according to the second aspect of the invention, in addition to the above effects, since the key input corresponding to the encryption only needs to be performed once, the operation becomes extremely simple.
