Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present utility model relates to a printer device, and more particularly to a print paper position determination means.

[0002]

[Prior Art]

 A conventional printer device has a print position control unit that controls the start and end of printing one line, a print control unit that converts and controls character codes, etc. according to a print request from a higher-order print data control device, and a print control unit. It is equipped with a printing unit that prints on paper according to the print control signal from the control unit.The position of the printing paper is set by the cut paper feeder.If there is no cut paper feeder, the user sets the position of the paper. It was

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional printer device, since the digit position for printing is fixed, printing is started regardless of the position where the printing paper is set. Therefore, it is necessary to properly adjust the setting position of the printing paper that influences the quality of the printing position, especially in the case of printing over multiple pages, there is a drawback that it is difficult to match the printing start position for each page. .

An object of the present invention is to provide a printer device having a print paper position determination function capable of automatically detecting a set position of print paper and starting printing from a predetermined position of the paper.

[0005]

[Means for Solving the Problems]

 According to a first aspect of the printer device of the present invention, a code indicating a character and a symbol is converted into a print signal in response to a print position control unit for controlling the start and end of printing of one line and a print request from a higher print data control device. In a printer device having a print control unit for converting and outputting a print control signal for controlling printing, and a print unit for printing on paper by the print control signal, a light emitting unit and an optical signal from the light emitting unit are provided. An optical sensor having a sensor for detecting the position of the inserted sheet is automatically detected by the output of the sensor, and an optical sensor for detecting the position of the sheet is provided. There is.

According to a second aspect of the present invention, since the light emitting section automatically detects the position in the width direction of the sheet, it is possible to move laterally in the width direction of the sheet, and the sensor outputs an optical signal from the light emitting section. The printer device according to claim 1, wherein the printer device is provided so as to laterally extend in the width direction of the paper so as to detect the position of the inserted paper and detect the position of the inserted paper.

[0007]

[Action]

 Light sensor of the paper position detector detects the position of both ends of the set print paper by the sensor detecting the optical signal from the light emitting part, and the position of the paper is set. The data of is output to the print position control unit. The print position control unit calculates the print position based on the information from the optical sensor paper position detection unit and sends it to the print control unit. As a result, the print control unit detects a predetermined position at the start of printing, and printing can be performed from the predetermined position.

【Example】

 Next, a printer device of the present utility model will be described with reference to the drawings.

FIG. 1A is a configuration block diagram of an embodiment of the present invention, and FIG. 1B is a schematic plan view of the optical sensor sheet position detection unit shown in FIG. 1A.

As shown in the block diagram 1 (a), in this embodiment, in addition to the conventional print position control unit 2, print control unit 4 and print unit 5, an optical sensor paper for detecting the position of the paper is used. It has a position detection unit 1 and is connected to a print data control device 3 of a higher order via a data signal path 6. The optical sensor paper position detection unit 1 automatically detects the insertion position of the print paper when the paper is fed to the printer device, and inputs the data to the print position control unit 2. The print position control unit 2 calculates the print position from the data and sends the information to the print control unit 4. The print control unit 4 detects the print position based on the print position information and sends the information to the print unit 5 together with the print character and symbol code information of the print data signal from the print data control device 3. With this information, the printer head of the printing unit 5 automatically moves to a predetermined position to start printing.

Next, an embodiment of the optical sensor paper position detection unit of the present invention will be described with reference to FIG. 1B. The optical sensor paper position detection unit 1 is located near the paper insertion port of the printer device. A light emitting portion 11a that can move laterally in the width direction of the paper, a light detecting portion 11b having a sensor extending laterally in the width direction of the paper, and a printing portion 15 are provided. Further, the paper feed roller 18 is a feeding device on which the paper 17 is mounted. In this example, the light emitting unit 11a and the printing unit 15 are integrated, but they do not have to be integrated.

The operation will be described. The light emitting section 11a laterally moves in the width direction of the paper to generate an optical signal, and the light detecting section 11b senses the optical signal to control the data in the printing position. The sheet insertion position is decoded by sending the sheet to a unit (not shown). After that, as described above, the print control unit and print unit operate to automatically start printing at a predetermined position on the paper.
