Reference numeral 1 denotes a CPU (central process in
g unit). A ROM (read only memory) 2 in which program data of the processing performed by the CPU 1 is stored, a RAM (random access memory) 3 in which an area of various memories used when the CPU 1 performs the processing, various data and application programs are stored. A hard disk interface 5 for controlling data transmission with the hard disk device 4 to be stored, a clock circuit 6 as a clock means for clocking the current date, and a clock 2 printed on a print medium
Communication interfaces 8 for controlling data transmission with a two-dimensional code reader 7 as an image reading means for reading an image of a dimensional code are connected to the CPU 1 via a system bus 9. The CPU 1 prints data on the keyboard interface 11 for controlling data transmission with the keyboard 10, the display controller 13 for controlling the display unit 12, the drawer unit 14 for storing and managing money, the receipt and the journal via the system bus 9. And a printer unit 15 for performing the operation.

The ROM 2 is composed of a flash ROM which is rewritable block by block as a memory as a storage means, and has a memory map as shown in FIG. The add-in loader area 21 includes the following 2
In an area for storing a program for executing a dimension code reading process, a keyword serving as an instruction is searched from the read two-dimensional code data, and the data is stored in a corresponding memory area in an optimum manner according to the content of the read code. Is set to The variable parameter area 22 is
This area stores parameter data. The extended function area 23 is an area for storing program data for adding a new function.

The hook parameter area 24 is an area for storing an address conversion table indicating an address pointer corresponding to a required function. Therefore, by changing the address stored in the hook parameter area 24, the program stored at the new address can be executed. Fixed parameter area 2
Reference numeral 5 denotes an area for storing and holding unchanged parameters which are generally used by a system program described later. The system area 26 is an area in which system program data for executing basic processing provided from the beginning by the CPU 1 is stored. The variable parameter area 22, the extended function area 23, and the hook parameter area 24 need to be rewritable, so they must be formed in a rewritable memory.
1. Since the fixed parameter area 25 and the system area 26 do not need to be rewritable, they may be formed in a read-only memory.

FIG. 3 is a diagram showing a flow of a two-dimensional code reading process performed by the CPU 1 when the two-dimensional code reader 7 performs a two-dimensional code reading operation. First,
It is in a standby state until the two-dimensional code reading by the two-dimensional code reader 7 is completed. When the two-dimensional code reading is completed, the two-dimensional code data is decoded from the two-dimensional code image data obtained by the two-dimensional code reading, and commands and the like are analyzed for the two-dimensional code data (two-dimensional code analysis means). .

Based on the analysis result of the two-dimensional code data, it is determined whether or not the two-dimensional code data includes a keyword serving as an instruction. If it is determined that there is no keyword, that is, there is only a normal code, the two-dimensional code reading process is terminated. When the two-dimensional code reading process is completed, the system program stored in the system area 26 is executed, and the two-dimensional code data having only the normal code is passed to the process by the system program, and an appropriate process is performed. .

If it is determined that there is a keyword, it is determined in step 1 (ST1) whether or not there is update data in the two-dimensional code data. Here, when it is determined that there is no update data, as a process of step 2 (ST2), it is determined whether or not the instruction is a command for updating a program by a keyword. Here, if it is determined that a command for updating the program by the keyword, that is, a new function is to be added, the read two-dimensional code data is set in the extended function area 23 as program data (
Program placement) (function changing means), and corresponding to the setting of this program data in the extended function area 23 (so that the program data can be executed), the address of the hook parameter area is changed (function changing means). ,
This two-dimensional code reading process is terminated. Upon completion of the two-dimensional code reading process, a system program is executed.

When it is determined in step 2 that the command is a command to update a parameter by a keyword, the read two-dimensional code data is used as parameter data.
Set in the variable parameter area 22 (parameter setting)
Then, the address of the hook parameter area is changed (function changing means) so that the parameter data can be used, and the two-dimensional code reading process is terminated. Upon completion of the two-dimensional code reading process, a system program is executed. If it is determined in step 1 that there is update data, it is determined whether the current date obtained from the clock circuit 6 is earlier than the date specified by the update data.

If it is determined that the current date is not before the specified date of the update data (the current date matches the specified date or has passed the specified date), the process proceeds to the above-described step 2. Has become. If it is determined that the current date is earlier than the date specified in the update data, the update data and the two-dimensional code data are stored (registered) in the hard disk drive 4 (or another non-volatile memory), and the update data is stored. Is stored (registered) in the hard disk drive 4 (update date control means), and the two-dimensional code reading process is terminated. Upon completion of the two-dimensional code reading process, a system program is executed.

FIG. 4 is a diagram showing a flow of a power-on process performed by the CPU 1 at the time of power-on or reset. First, an initialization process for initializing a memory (RAM3 or the like) is performed, and when this initialization process is completed, the data registered in the hard disk device 4 (or another nonvolatile memory) is processed in step 3 (ST3). To determine whether or not there is an update reservation with update data that matches the current date obtained from the clock circuit 6.

If it is determined that there is no update reservation based on the update data that matches the current date, the power-on processing is terminated. Upon completion of the power-on processing, the system program is executed. If it is determined that there is an update reservation with the update data that matches the current date, the two-dimensional code data corresponding to the update data of this update reservation is called from the hard disk device 4 and the above-mentioned two-dimensional code reading process is performed from step 2 onward. Is performed (update date control means), and when this program update process is completed, the process returns to the above-described step 3 again.

In this embodiment having such a configuration, a system administrator at the headquarters can use a personal computer to execute an instruction creation application program and a two-dimensional code encoder based on a new specification of the apparatus, for example, as shown in FIG. Is created and printed out by a printer. This instruction sheet is printed with a two-dimensional code that encodes data (function change program) for executing the function update, along with a sentence written in characters so that a person can confirm the updated contents of the function. .

FIG. 6A shows an update (adaptation start date).
) And updated contents of functions (change of tax rate etc. (TAX), addition of change of reading code (CODE), addition of new function (NE
W)) and a keyword (not shown) are encoded into a two-dimensional code. FIG. 6 (b) shows a first program presented by adding a new function shown in FIG. 6 (a). (PROG1) and a keyword (not shown) are encoded into a two-dimensional code. FIG. 6 (c) shows the second program (PROG2) and the second program (PROG2) presented with the addition of the new function shown in FIG. 6 (b). This shows that a keyword (not shown) is encoded into a two-dimensional code.

At this point, the printed instruction is stored as an update record and stored in a database, and is used for managing the history of the function update of the electronic register. The instructions will be faxed (or mailed with a copy) from the headquarters to the location where the electronic register is located over the public line. In the case of facsimile transmission, the contents of the two-dimensional code can be accurately transmitted or restored by a two-dimensional code error correction function or the like with respect to image deformation and noise in the facsimile transmission. At the place where the electronic register is installed, the two-dimensional code reader 7 reads the two-dimensional code of the instruction sent by facsimile transmission or mail. Only by this operation, the function update of the electronic register is completed.

A description will now be given of a function updating operation performed automatically by the electronic register to which the present invention is applied after the two-dimensional code of the instruction is read by the two-dimensional code reader 7. If the read two-dimensional code is a normal code such as sales registration data, it is processed in a normal business process. However, in the two-dimensional code of the above-described instruction, a keyword is added. , The function update process is executed.

First, the date of the update (adaptation start date) is confirmed, and if the current date is earlier than the date of the update, the two-dimensional code data is reserved for update on the date of the update, and the two-dimensional code data is reserved. When the date comes, a function update process is executed based on the two-dimensional code data. If the current date matches the update date or has passed the update date, the function update process is immediately executed based on the two-dimensional code data.

As described above, according to this embodiment, the two-dimensional code reader 7 for reading the two-dimensional code of the instruction is provided, and the function is updated by the keyword included in the two-dimensional code data read by the two-dimensional code reader 7. By executing the above process, even a service engineer or a person who is not a programmer who is not a programmer can update the functions only by a simple operation of reading the two-dimensional code of the instruction with the two-dimensional code reader 7. it can. Therefore, when the instruction sheet is created, the time required for the function update processing can be substantially reduced. In addition, update data is added as a condition to a function update program that encodes into a two-dimensional code. If the current date is a date before the update date, the function update is performed until the update date. By postponing, it is not necessary to manage the adaptation start date, so that the two-dimensional code can be read for updating the function, and the operability can be improved.

Further, by issuing and distributing an instruction sheet in which a two-dimensional code encoding a program for executing a function update is printed, a plurality of electronic registers that are separately installed can be almost simultaneously transmitted. The same function update can be performed. In addition, if the instructions are stored, it is easy to manage the history of function updates, and it is possible to freely reproduce the various stages at the time of shipment, before and after the function update, regarding the problems related to the functions, The effect that function maintenance can be easily performed can be obtained.
