Description

Mechanical information display device {MECHANICAL INFORMATION DISPLAY DEVICE}

The present invention relates to a mechanical information display device, and more particularly, to a mechanical information display device that requires power only when output information is changed and can clearly output information to be output even without a constant power supply.

By using QR CODE or barcode, necessary information can be printed out with only white and black colors. In particular, QR CODE is a two-dimensional code with a grid pattern. Conventional one-dimensional barcodes can only store numeric information of around 20 characters, whereas QR codes contain up to 7,089 numbers, up to 4,296 characters (ASCII), and binary (8 bits). It can store up to 2,953 bytes and up to 1,817 Chinese characters.

As a device for outputting information such as QR CODE and barcode, all commercially available display devices can be utilized. For example, information may be output through LCD, OLED, electronic ink, and the like.

However, when QR CODE is output using LCD or OLED, there is a problem in that power is wasted because a constant power supply is required.

In addition, when QR CODE is printed with electronic ink, power is consumed only when changing the QR CODE, so power is not consumed during QR CODE output. It is difficult to express bright, clean white and sharp black, and it shows a weakness in visibility in an environment without lighting. In particular, there is a problem that the reader may not properly recognize it when it is used for output such as barcodes and QR codes that require a clear contrast ratio. In addition, electronic ink is not completely independent of pixel control, so it may leave a fine afterimage, which is not suitable for output such as QR CODE, where accurate information can be output only when the contrast between black and white is clear.

(Hereinafter, the part that outputs white of the output unit 10 will be referred to as the white element 11, and the part that outputs black will be referred to as the black element 12.)

An output rotation shaft 50 is disposed in the output unit 10, and the output rotation shaft 50 is provided to pass through the center of gravity of the output unit 10 so that the output unit 10 can rotate 360 degrees. . Here, in the output unit 10, when the white element 11 is disposed to face the outside, the black element 12 becomes invisible from the outside and can output white color. Conversely, the black element 12 is disposed to face the outside In this case, the white element 11 becomes invisible from the outside and can output black. Accordingly, each of the output units 10 can selectively output one of two types of information, black and white, and thus constitute a part of an information output device.

The conversion unit 20 capable of rotating the output unit 10 is provided to generate rotational moment in the output unit 10 by applying an external force to a point spaced a predetermined distance from the center of gravity of the output unit 10 can The conversion unit 20 may include a conversion unit housing 23 , a first converter 21 and a second converter 22 . In detail, an operation method of rotating the output unit 10 by the conversion unit 20 will be described in more detail with reference to FIGS. 3 and 4 below.

3 to 5 are flowcharts illustrating a process in which the output unit 10 of the mechanical information display device 1 according to the embodiment of the present invention is rotated by the conversion unit 20.

6 is a diagram for explaining a structure in which the first transducer 21 of the mechanical information display device 1 according to an embodiment of the present invention moves up and down.

가지의 정보를 출력할 수 있게 된다. 여기서 출력부(10)는 출력하고자 하는 정보의 종류에 따라 필요한 개수 이상으로 구비될 수 있다. Furthermore, since the output unit 10 may be provided in plurality, information may be more abundantly output. Specifically, the mechanical information display device 1 in which an arbitrary natural number n output units 10 are disposed

The branch information can be output. Here, the output unit 10 may be provided in a required number or more according to the type of information to be output.

For example, when a barcode is to be output by the mechanical information display device 1 according to an embodiment of the present invention, since the barcode is one-dimensional information, a desired barcode can be output in a configuration of 1 row and n columns (1*n). there is. Since the 13-digit EAN-13 barcode (country code (3 digits) + producer number (or seller number) + product number + checksum (1 digit)) used for products has a structure of 1 row and 13 columns, mechanical information display devices (1 ) is provided with 13 or more output units 10 having a bar structure in which the other axis is longer than one axis, it is possible to output EAN-13 barcodes.

As another example, a case of outputting a QR CODE to the mechanical information display device 1 according to an embodiment of the present invention may be mentioned. QR CODE is two-dimensional information, and there are a total of 40 standards, starting with version 1 (21 × 21 cells) and increasing by 4 cells each horizontally and vertically, until version 40 (177 × 177 cells). For example, in order to output the version 1 QR CODE of the double 21×21 cell standard to the mechanical information display device 1 according to the embodiment of the present invention, the square-shaped output unit 10 has a total of 21 rows and 21 columns When 441 are arranged, the version 1 (21×21 cell) QR CODE can be completely output with the mechanical information display device 1 according to the embodiment of the present invention.

When a plurality of output units 10 are provided, the above-described support structure 13 may be made of an elastic material and formed in a lattice shape capable of supporting each output unit 10 .

In addition, when the output unit 10 is provided in the form of a matrix, the output rotation shaft 50 penetrating the center of gravity of the output unit 10 includes a plurality of output units 10 disposed along the longitudinal direction of the rotation shaft. All may be provided to pass through.

When information such as QR CODE is output to the plurality of output units 10 in the form of a grid, it can be used to display information that does not need to be changed frequently. For example, by arranging the mechanical information display device 1 according to the embodiment of the present invention on the dashboard of a shared car or rental car, current user information can be displayed only while the user is using the car. Shared cars or rental cars that are used by many and frequently change car users are inappropriate to post fixed user information like privately owned cars. Conversely, if vehicle user information is posted using LCD or OLED for frequent change, the vehicle battery may be discharged due to continuous power consumption. In addition, if the vehicle user information is posted using electronic ink, power is not consumed except when the information is changed, which can solve the vehicle battery discharge problem. However, since the interior of the vehicle may be dark due to tinting, etc. QR codes expressed in ink are inevitably less recognizable. In addition, since electronic ink often leaves afterimages due to technical limitations, there is a possibility that an error may occur in the output of information such as QR CODE. Therefore, the mechanical information display device 1 according to the embodiment of the present invention, which does not consume power at all times and can post accurate information with a clear contrast ratio, is a conventional output device in displaying user information for a certain period of time in a shared car or rental car. can be used more effectively. In addition, by arranging the mechanical information display device 1 according to an embodiment of the present invention on a store shelf, it is possible to disclose barcodes or price information of goods that may change from time to time. Similarly, it is possible to contribute to office automation by displaying the LOT number of a specific product in a factory with the mechanical information display device 1 according to an embodiment of the present invention. The above examples are only a small number of examples in which the mechanical information display device 1 according to the embodiment of the present invention can be used, and it is obvious to those skilled in the art that the use of the present invention is not limited to the above examples and there may be various uses. do.

7 is an exemplary view of a path along which the moving unit 40 of the mechanical information display device 1 according to an embodiment of the present invention moves the converting unit 20.

The moving unit 40 may move the converting unit 20 under the plurality of output units 10, and a driving force is applied to a belt (not shown) and a belt (not shown) supporting the lower side of the converting unit 20. It may include a third motor 42 that applies.

Referring to FIG. 7, the moving unit 40 moves in one direction, changes its position in a direction perpendicular to the moving direction, and then moves in the opposite direction to the one direction repeatedly, a so-called zigzag path. The conversion unit 20 can be moved. For this movement, a belt (not shown) disposed in a zigzag pattern may be provided.

The conversion unit 20 is moved by the moving unit 40 and is an output unit that needs to change the exposure surface (from the white element 11 to the black element 12 or from the black element 12 to the white element 11). By rotating (10), the output information can be changed. It goes without saying that the moving unit 40 can move the transforming unit 20 along another path that can appropriately move the transforming unit 20 even if it is not the aforementioned zigzag path. For example, by using a plurality of belts, one end and the other end of the moving unit 40 are vertically provided with belts that provide movement force only vertically, and between them, the required number of belts that provide movement force in the horizontal direction are provided horizontally. Thus, the belt can be arranged so that the moving part 40 can be placed at all necessary positions of the output part 10 .

8 is a cross-sectional view for explaining the support structure 13 supporting the output unit 10 of the mechanical information display device 1 according to the embodiment of the present invention.

Since the output unit 10 must selectively output black or white information, it must be able to maintain a stopped state except when rotated by the conversion unit 20 . Therefore, the mechanical information display device 1 according to the embodiment of the present invention is coupled to the output unit housing 14 to support the lower portion of the output unit 10 in order to prevent the output unit 10 from rotating unintentionally. A support structure 13 may be further included. The support structure 13 is made of a material having elasticity such as rubber or synthetic resin, and when the output unit 10 is rotated by the conversion unit 20, it bends flexibly and prevents the rotation of the output unit 10. After the output unit 10 has finished rotating and stopped, the support structure 13 bent by the elastic force can return to its original shape, and no external force is applied to the output unit 10. In a state in which no pressure is applied, the output unit 10 may be provided to support it so as not to rotate.

9 is a block diagram illustrating a signal flow of the controller 30 of the mechanical information display device 1 according to the embodiment of the present invention.

Referring to FIG. 9 , the controller 30 may include a processor 31 and a memory 32 . The control unit 30 may control the conversion unit 20 to expose either the white element 11 or the black element 12 to the outside by rotating the output unit 10 . Specifically, the control unit 30 operates the conversion unit 20 to convert the output unit 10 when the target exposure surface and the current surface exposed by the output unit 10 are different according to information input from the user. Exposure information can be changed.

In addition, when a plurality of output units 10 are configured, the positions of the plurality of output units 10 having different target exposure surfaces and surfaces currently exposed by the output units 10 are stored, and the stored output units 10 After moving the conversion unit 20 with the position of ) as the target position, the exposure information of the output unit 10 may be changed by operating the conversion unit 20 . By repeating such movement and conversion, output information by the plurality of output units 10 can be changed.
