Description

[Detailed Description of the Invention] The present invention relates to an electronic cash register equipped with a printing device for issuing a receipt and a stamp mechanism for printing a store name, etc. on the issued receipt. This relates to a device that automatically detects when it is time to convert or replenish roll paper for printing, ink for stamping mechanisms, ink ribbons, or batteries for holding various registration registers and alerts the operator. .

Conventionally, in such electronic cash registers, replacing the roll paper and refilling the ink in the stamping mechanism were carried out entirely by the operator, with the operator checking the status each time.

Therefore, the operator is required to inspect consumable parts each time the machine is operated, which is a very troublesome problem for the operator.

In addition, some roll paper is equipped with a device that mechanically detects when the diameter of the roll paper has become smaller and warns that it needs to be replaced, but the mechanical mechanism for this detection is complicated, and Since this detection accuracy is also poor, it can only warn that the roll paper is nearing the time to replace it, and even if there is roll paper left, it is uneconomical to be forced to replace it because of this warning.

In view of the above-mentioned points, the present invention provides a highly accurate and easily configured device that detects the condition of consumable parts using only an electrical circuit configuration and issues a warning for replacement.

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the present invention, and FIG. 2 is a diagram showing the configuration of the display section.

In FIG. 1, reference numeral 1 denotes a counter means into which a signal output in connection with the use of consumable parts is introduced when the register is operated, and performs a counting operation in response to the input signal.

In the illustrated embodiment, a counter 1A introduces a stamp signal S and a paper feed signal F and performs counting operations in response to these signals.
, equip 1B.

Reference numeral 2 denotes a storage unit into which information such as the number of times a consumable part can be used, which indicates the consumption period of the consumable part, is introduced from the outside.In the embodiment shown in the figure, the storage unit 2 is into which information about the number of times a stamp can be used is introduced. It has a storage section 2B in which information regarding the number of lines used on the roll paper is stored.

That is, assuming that the number of times that the ink V of the stamp mechanism can be used by one ink replenishment is 10,000, a numerical value rlO000j is introduced into the storage section 2A.

Regarding rolled paper, the number of lines that can be printed on one roll paper is introduced.

Reference numeral 3 denotes a judgment circuit into which the count information of the counter means 1 and the memory information of the storage means 2 are introduced and which compares these image information to detect a coincidence. For example, the count information in response to the stamp signal SF of the counter 1A and the memory The section compares information on the number of times stamps have been used by two people, and when they both match, outputs a match signal A, and outputs a paper feed signal F from the counter 1B. When the two match, a match signal B is output.

Reference numeral 4 designates a flip-flop circuit that is set by the match signal output from the determination circuit 3, and 4A and 4B are provided corresponding to the match signals A and B.

Reference numeral 5 denotes a display device that warns the operator based on the output of the flip-flop circuit 4, and as shown in FIG. The lamp 5A is turned on to indicate ink replenishment, and the lamp 5B is turned on to indicate paper replacement in response to the set output of the flip-flop 4B.

Therefore, to explain about ink replenishment of the tap mechanism,
The stamp can be used a total of 1 times with one ink refill.
- When 1000 OJ times is determined according to the specifications, operate the numeric keys to introduce and store 10000 J into the storage means 2 in advance, and after that, the register performs normal registration and receipt issuing operations by using it. However, the counter 1 counts up in response to the stamp signal that drives the stamp mechanism.

Since the stamp mechanism performs a printing operation each time a restamp signal arrives, a counter 1 is incremented each time a stamp signal arrives to count the number of times the stamp has been used.

The count contents of the counter 1 and the storage information (1
0000) are respectively sent to the judgment circuit 3 and a match detection is performed.

By using the register, the count contents of counter 1 can be changed to [oo
When ooJ is reached, the judgment circuit 3 detects a match with the contents of the storage means 2, outputs a match signal A, and sets the flip-flop 4A.

In response to the seven outputs from the flip-flop 4A, the lamp 5A lights up to warn the operator of ink replenishment.

In the above description, the counter is incremented by one in response to an input signal, and the determining circuit detects a match between the contents of the counter and the contents of the storage means.
In response to the input signal, the contents of the storage means are sequentially subtracted [7] to perform a counting operation, and the judgment circuit detects that the storage means becomes zero state due to the counting operation, and in response to this detection signal Ki, the lamp is turned on. It can also be turned on.

Furthermore, the output signal from the flip-flop 4 in FIG. 1 can be fed back to the input device, and while the output signal is being derived, the operation of the input device can be locked so that no input can be made.

This is to prevent operations such as blank printing from being performed by operating the input device when there is no roll paper or ink.

Further, in the above explanation, the case where a warning is given to replace or replenish the roll paper and ink is shown, but the warning also applies to the warning when pressing the button to replace the ink ribbon or change the battery to compensate for the power outage of various registration registers. It is available.

Furthermore, regarding the display for issuing a warning, in the above description, a configuration was shown in which lamps 5A and 5B were provided depending on the content of the warning, but numerical information is displayed without providing a lamp.

Using the display section 5C, a specific symbol can be displayed depending on the content of the warning.

In this way, the present invention automatically converts or replenishes the consumable parts installed in the register. C. As a warning device, a storage means is installed and stored in advance to store information such as the number of times a consumable part can be used, which is necessary for replacing or replenishing the consumable part, and information related to the use of the consumable part when operating the register. A counting means that performs a counting operation in response to a signal corresponding to the information introduced into the storage means among the output signals, and a judgment circuit means that detects a match between the count of the counting means and the information introduced in advance. and warning means for warning the replacement or replenishment of consumable parts related to the determined information in response to a signal output when the judgment circuit means detects a match, This warning is automatically issued by an electric digital control circuit structure, and the operator is not forced to check each time the register is operated, making it extremely convenient to use and greatly improving the detection accuracy. This eliminates the inconvenience of being forced to replace the roll paper or ink even though it remains, due to a warning, and the roll paper or ink can be used economically.

Moreover, this control section can be made compact and can be easily installed in a register.
