CN201669982U - Bill advertising integrity automatic breaking device - Google Patents

Abstract

The utility model discloses a bill advertisement integrity automatic breaking device belonging to the automatic control device range. The utility model is a bar code recognition circuit, which is connected in series with an infrared light-emitting diode LED and a variable resistor VR, and four ports of a photosensitive element U are respectively connected with an infrared diode LED, a power supply VCC, grounding and an I/O port of a POS machine CPU. Divide the length of the entire advertisement content into 16 equal parts, and set an identification code for each part. Use four infrared light-emitting diodes to receive the identification code. When the identification code on the back of the bill passes through the infrared light-emitting diodes, due to the difference in the identification codes, the four infrared light-emitting diodes will reflect, and different combinations represent different identification codes. The photosensitive element accepts and sends to the CPU of the POS machine. The utility model can ensure the integrity of the advertising content on the back of the bill to the greatest extent while the bill is printed. Greatly protect the interests of users.

Description

Bill advertising integrity automatic breaking device

technical field

The utility model belongs to the scope of automatic control devices, in particular to a device for automatically breaking bill advertisement integrity.

technical background

At present, in shopping malls, supermarkets or other commercial transactions, merchants often print public service advertisements or commercial advertisements on the back of shopping receipts printed for customers, in order to achieve public welfare publicity, corporate brand image display or promotion promotion

information purposes. However, because the number of commodities purchased by each customer is different, the length of the shopping receipt is also quite different, so the advertisement content on the back of the bill is often incomplete during the printing process. In this way, customers who get the bill cannot see the complete advertisement, which greatly reduces the effectiveness of the advertisement, and the advertising cost invested does not get the corresponding publicity effect.

Utility model content

The purpose of the utility model is to provide an automatic cutting device for the completeness of the bill advertisement in view of the incompleteness of the advertisement content caused by the different lengths of the bill during the printing process of the advertisement content on the back of the bill. It is characterized in that the utility model is an identification code circuit, the pin 2 of the photosensitive elements U1-U4 of the circuit is connected with the power supply VCC, the pin 3 of the photosensitive elements U1-U4 is connected with the power ground GND, and the variable resistors VR1-VR4 are respectively It is connected in series with infrared diodes LED1-LED4, and the infrared diodes LED1-LED4 are connected to pin 1 of photosensitive elements U1-U4 respectively, and pin 4 of photosensitive elements U1-U4 is connected to the I/O port of the CPU of the POS machine. Pin 4 of U1-U4 is respectively connected to the power supply VCC through resistors R1-R4.

The beneficial effect of the utility model is that the completeness of the advertisement content on the reverse side of the bill can be guaranteed to the greatest extent while the bill is printed. The automatic cutting device can ensure the integrity of the bill advertisement as much as possible while printing the content on the front of the bill. At the same time, when the advertisement content is more than a certain amount of the bill content, the printing will be stopped in time after judgment, so that paper will not be wasted.

Description of drawings

Fig. 1 is the schematic diagram of the identification code circuit of the present utility model.

Figure 2 is the identification code setting on the back of the bill.

Detailed ways

The utility model belongs to the scope of automatic control devices, in particular to a device for automatically breaking bill advertisement integrity. Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 1 shows the identification code circuit. In this circuit, the pin 2 of the photosensitive element U1-U4 is connected to the power supply VCC, the pin 3 of the photosensitive element U1-U4 is connected to the power supply ground GND, the variable resistors VR1-VR4 are respectively connected in series with the infrared diodes LED1-LED4, and the infrared diodes LED1- LED4 is respectively connected with pin 1 of photosensitive elements U1-U4, and pin 4 of photosensitive elements U1-U4 is connected with the I/O port of the POS machine CPU, and pin 4 of photosensitive elements U1-U4 is connected through resistors R1-U4 respectively. R4 is then connected to the power supply VCC.

The principle of the above circuit is to set the identification code before the start part of the advertisement and after the end part, as shown in Figure 2, the identification code setting on the back of the bill is used to judge the start and end of an advertisement. At the same time, the length of the entire advertisement content is divided into 16 equal parts, and an identification code is set for each part, and four infrared light-emitting diodes are used to receive the corresponding identification code. When the identification code on the back of the bill passes through the infrared light-emitting diode, due to the difference in the identification code, It will reflect the four infrared light-emitting diodes, and different combinations represent different identification codes, which are then received by the photosensitive element and sent to the CPU of the POS machine, so as to judge the position of the advertisement on the back of the bill and determine whether the bill printer stops printing.
