Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register in which the types of business operations that can be permitted to be executed depending on the shape of the key used are stored in advance in a table (memory) of a storage unit.

[Prior Art] In a general electronic cash register, the electronic cash register's [Registration] [Inspection] [Checkout] [
A control key is provided that is operated using a task designation key for selecting and specifying each task such as [minus registration] [setting]. [Register] means to cumulatively register the sales data such as the department code, sales amount, and number of sales items of the sales products entered manually from the keyboard into each memory area such as the sales registration file that is created in the storage unit. This is a normal sales registration operation that calculates the total amount for each customer, issues a receipt, and exchanges money for the total amount with the customer. Moreover, [inspection] is a task of printing out each data value cumulatively registered in each memory area of the storage unit on a receipt or the like as an inspection report at a predetermined fixed time, for example, after the start of sales operations. Also, [Settlement Co. is, for example, 10
This is a job to print out each data cumulatively registered in each memory area in the storage unit as a settlement report at the end of the job, and to clear the contents of each memory area that have already been printed out. Furthermore, [Minus Registration] is a process to reduce the sales data accumulated in each memory area due to returns, etc., and [Setting] is a process to reduce the amount of sales data accumulated in each memory area due to returns, etc. This is the task of setting various fixed data required for registration tasks. Each of the above-mentioned tasks can be easily executed using the above-mentioned one task setting key.

However, among the above-mentioned tasks, general cashiers only need to perform [registration], and [inspection] [
There is no need to perform tasks such as [Settlement] and [Settings]. In particular, since most of the data accumulated in each memory area of the storage unit is highly confidential, it is difficult to easily show highly confidential data even to the cashier during the checkout process. This is often not good for business.

On the other hand, the person in charge of the sales floor needs to be able to perform all of the tasks listed above.

In order to solve this problem, as shown in FIG.
It has been considered to have two types of keys 2a and 2b, 2a and 2b, respectively. When each operator inserts his or her own key into the keyhole 3 and rotates it in a certain direction, the switching contact 4 shown in FIG.
As shown in Figure (C), the rotation range of the cashier key 2a is mechanically limited by the keyway shape 1 from the power on/off control position to the [registration] position, and the rotation range of the manager key 2b is The range can be set for all tasks from the minus registration 1 position to the settlement position.

[Problems to be solved by the invention] However, as described above, the keyway shape 1 of the 8 keys 2a, 2b
Electronic cash registers that limit the types of business operations that are permitted to be executed have also had the following problems. That is, the type of work that each person can perform in accordance with the keyway shape 1 of the keys 2a, 2b owned by each person is uniquely determined by the mechanical configuration shown in FIG. However, some users of electronic cash registers, ie, store managers, may have the cashier perform inspection and checkout. In addition, a head cashier may be placed between the cashier and the person in charge of the sales floor, and this head cashier may be given permission to perform inspections and negative registrations.

In this way, the range of permission for each user to perform each task changes, so manufacturers of electronic cash registers mechanically create various combinations of the rotation range of the keys 2a and 2b for each user. need to be executed. Therefore, not only the types of keys 2a and 2b increase, but also the types of keys 2aa and 2b increase.
, 2b are inserted into the keyhole 3, it is necessary to prepare a plurality of types of key switch bodies. As a result, each part of the key part has to be produced in small quantities and in a wide variety of products, which becomes an impediment to improving the productivity of the electronic cash register as a whole.

The present invention has been made based on these circumstances, and its purpose is to set the types of tasks that can be executed depending on the key shape in a table (memory) in the storage unit, so that even if the same key The key part can have the same mechanical configuration even if the range of permitted work differs.
An object of the present invention is to provide an electronic cash register that can improve productivity while maintaining the confidentiality of output data.

[Means for Solving the Problems] The electronic cash register of the present invention includes a task specifying means for selecting and specifying each task such as registration 1 inspection and payment, a plurality of keys having mutually different key shapes, and a keyhole. A key switch section that outputs key codes corresponding to the shapes of the eight inserted keys, and a business execution permission memory that stores execution permission information for each of the jobs for each key code are provided. When one task is specified, it is determined whether or not the specified task can be executed according to the execution permission information corresponding to the key code input from the key switch unit in the task execution permission memory.

[Operations] With an electronic cash register configured in this way, when one business is designated by the business specification means with the key inserted into the keyhole of the key switch section, the insertion in the business execution permission memory is disabled. The specified task is executed only when the specified task is stored as execution permission information in the area corresponding to the key code of the key. Therefore, it is possible to identify the tasks that are permitted to be executed depending on the type of key. Further, by changing the setting contents of the business execution permission memory, the type of the above-mentioned permitted business can be easily changed.

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

FIG. 2 is a perspective view showing the electronic cash register of the embodiment. As shown in the figure, a keyboard 6 is provided on the front surface of the casing 5, and a display section 7 is provided on the top of the casing 5 for electronically displaying the department code of the sold product, the total sales amount, etc.; A receipt issuing port 8 and a drawer 9 for storing cash are provided at the bottom.

Furthermore, a customer display section 10 having the same configuration as the display section 6 is attached to the top surface of the housing 5. Furthermore, a key switch section 11 is provided adjacent to the keyboard 6 for controlling the power supply on and off and for inputting the key code manually.

As shown in FIG. 3, the keyboard 6 has number keys 12 for inputting the sales amount, sales quantity, etc. of the sold products.
．． In addition to keys for sales registration such as a department key 13° indicating the classification of products and a deposit/cash key 14 for calculating the total amount of products sold to customers, there are also keys for [registration], [inspection], and [payment]. ] [Five task designation keys 15 are arranged as task designation means for selecting and specifying each task such as minus registration [setting]. Note that each business specification key 15 is a lock type key, and if the key is operated twice in succession, it will return to its original state. Additionally, multiple keys cannot be held down at the same time.
When one key is pressed down, the other pressed keys return to their original state.

In the key switch section 11, as shown in FIGS. 4(a) and ('b), when the key 17 is inserted into the keyhole 16 and turned clockwise to the on position, the power of the device is turned on. . This key 17 has three positions a, b, and where the key groove 18 should be carved.
c is specified, and in FIG. 4(b), key grooves 18 are carved at positions a and C, and the key grooves 18 are
is not engraved. Also, the keyway 19 connects the key 17 to the keyhole 16.
This is a keyway common to the six keys 17 for inserting into the key and rotating it to the on position.

FIG. 4(c) is a diagram showing a state in which the key 17 is inserted into the keyhole 16 of the key switch section 11 and rotated to the on position. The positions a and b of the key 17 are shown in the figure.

A micro switch 20a is placed at a position opposite to C.
, 20b, 20c are arranged, and if a keyway 18 is carved in each position a, b, c, a microswitch 20a corresponding to that position.

20b and 20c are turned on. Therefore, position a
, b, and c, it is possible to set seven types of keys 17, and the key switch section 11
is each microswitch 20a.

Seven types of key codes can be set corresponding to the on/off states of 20b and 20c.

FIG. 5 is a block diagram of the electronic cash register. The CPU (Central Processing Unit) 21 has a built-in arithmetic circuit, etc., and performs various arithmetic processing based on input information from the keyboard 6 and the key switch section 11. A ROM 25 that stores fixed data such as programs for each of the above-mentioned operations via a data bus 23 and a control line 24, and a ROM 25 that is backed up by a battery when the power is cut off and sales data such as the sales amount of each product that is manually operated and each key. The RAM 26, which stores a task execution permission memory, etc., which stores execution permission information for each task for each code, is operated. Also, a key code input circuit 27 into which the key code from the key switch circuit 11 is manually input, a keyboard input circuit 289 into which the key signal from the keyboard 6 is input manually, and a display section 7.10.
A display control circuit 29 that sends a display signal to. A printer control circuit 31 of a dot printer 30 that prints out sales data, total amount, various inspection reports, settlement reports, etc. on a receipt is connected to the CPU 21 via a data bus 23 and a control line 24, respectively.

In the RAM 26, as shown in FIG. 6, there is a sales registration file R1 for cumulatively registering sales data such as the number of sales items and sales amount of each sales product entered manually from the keyboard 6, for example, by department code, and various calculations. In addition to a work buffer R2 for carrying out the work, a totalizer R3 for calculating the total price of products sold to -1 customers, and the like, a work execution permission memory R4 is formed.

As shown in FIG. 1, the task execution permission memory R4 stores the five tasks [registration code [inspection] [settlement code] [minus] for each of the seven types of key codes 1 to 7 inputted from the key switch circuit 11. Each execution permission information indicating whether or not to permit the execution of [Settings] is set. Then, if [1] is set in the corresponding area, execution is permitted and [
0], execution is not permitted.

In the embodiment, the key 7 with the key code [1] is used as a cashier key, and only the [registration] task can be executed.

Similarly, the key code [two keys 17 are used as keys for the head cashier] enables execution of three types of work: [registration], [inspection], and [minus registration]. Also, key code [3]
The key 17 is used as a key for the person in charge and is able to execute all tasks. Further, the key 17 with the key code [4] is used as a key for service personnel, and only the [setting] task can be executed.

Note that the keys 17 with key codes [5], [6], and [7] are not used for the time being and are kept as spares.

The CPU 21 is configured to execute the main routine according to the flowchart of FIG. 7 when the power of the apparatus is turned on. That is, the key 17 is connected to the key switch section 1.
1 is inserted into the keyhole 16 and rotated to the on position, the power is turned on, and after performing predetermined initial processing, it waits for the business designation key 15 to be pressed down. When one business designation key 15 is pressed down anew or has been pressed down from the beginning, the key code input manually from the key switch section 11 via the key code input circuit 27 is read. Then, the task execution permission memory R4 of the RAM 26 is searched using the read key code. Then, among the execution permission information for each of the five jobs in the corresponding key code, the execution permission information for the job specified by the job designation key 15 is read out. If the execution permission information for the relevant business is [1], it is determined that this business is a business that should be executed, and the execution processing of the relevant business is started.

In addition, if the read execution permission information is [0], the key 17 inserted into the key switch section 11 is not permitted to execute this task specified by the task specification key 15, so the display is displayed. An error message is displayed on the sections 7 and 10, and an alarm sound is emitted to call the operator's attention.

With the electronic cash register configured in this way, after inserting the key 17 into the key switch section 11 and turning it to the on position to turn on the power, one task can be performed using the task designation key 15 on the keyboard 6. In the specified case, this specified task is executed only if it is a task that is permitted to be executed on the inserted 1!17. Therefore, on the contrary, it is possible to define the tasks that can be permitted to be executed depending on the type of the key 17.

Further, since the above-mentioned tasks that can be executed are set in the task execution permission memory R4 of the RAM 26, the setting contents of the task execution permission memory R4 can be arbitrarily changed in a separate [setting] task. This means that when manufacturing electronic cash registers, all electronic cash registers should be manufactured with the same specifications, and the contents of the business execution permission memory R4 should be set according to each user's wishes when they are installed at each user's sales floor. . Therefore, while maintaining the function of arbitrarily specifying the tasks that can be executed depending on the type of key 17,
The productivity of electronic cash registers can be improved.

[Effects of the Invention] As explained above, according to the present invention, the types of tasks that can be executed are stored in advance in the table (memory) of the storage unit based on the key shape.
I am trying to set it to . Therefore, even if the scope of business permitted by the same key is different, the key portion can have the same mechanical configuration, and the productivity of the electronic cash register can be improved while maintaining the confidentiality of inspection data and payment data.
