Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register in which a setting switch is housed in a sealed housing to prevent setting data necessary for registration from being tampered with during the process.

[Prior Art] Generally, an electronic cash register has a built-in clock circuit and counter circuit backed up by a battery, and records the department code, number of items sold, sales amount, etc. of each product sold to one customer. When the manual operation of the sales data key is completed and the closing key such as the deposit/account key is pressed, the date and time of the point of sale read out from the clock circuit along with the total amount on an internal recording paper called a receipt and journal. The issue number (receipt number) will be printed out. Furthermore, if a plurality of electronic cash registers are installed, the electronic cash register number is also printed out at the same time. In addition, depending on the electronic cash register, the above date and time is 2nd time.

Some have a receipt number or electronic cash register number printed at the beginning of the receipt.

In addition, the above date and time, receipt number (report number), and electronic cash register number are also printed out in the settlement report showing the daily sales total etc. that is printed out during settlement operations performed after the day's business ends. .

Normally, the above-mentioned work of setting the date and time, receipt number, and m-child cash register number is performed when the electronic cash register is first installed or when the electronic cash register is changed in February of the year. In other words, it accurately corrects the clock circuit that is running late or ahead to the current time, clears the count value of the receipt number counter to O, and further sets the electronic cash register number if the number of installed electronic cash registers increases or decreases. Try again. Further, the above-mentioned data setting operations are normally performed by manual key operations on a keyboard provided on the front of the housing.

[Problems to be Solved by the Invention] However, the electronic cash register in which each of the above settings is entered manually from the keyboard provided on the front of the case has the following problems. there were. That is, in some countries or regions, the tax office records information in the journal or settlement report of each electronic cash register in order to understand the financial status of the merchant and confirm that the declared income is correct. You may want to check the total daily sales amount.

However, if you can easily change the setting data such as the date 9 time, receipt number (report number), electronic cash register number, etc. printed on the journal or settlement report as described above, these date 9 time 1 numbers can be changed. It is possible to falsify and reduce the number of journals and settlement reports to make the total sales amount lower than the actual value.

The present invention has been made based on the above circumstances, and its purpose is to improve the date 2 required for registration.
By housing the setting switch for setting setting data such as time, electronic cash register number, receipt number, etc. in a sealed housing, we have created an electronic cash register that prevents these setting data from being easily tampered with during the process. It is about providing.
