The base supply portion 105 serves to supply a base that can be adhered to the object. The base supplied from the base supply unit 105 may be of two types, one of which is composed of one surface on which the image is output and adhered to the surface of the object to be attached, and the other surface on which the image to be output is formed, for example It is similar in form to a sticky sticker or a correction tape. In addition, when the base is composed of a paint-like ink material and is output to the object, the white ink (or paint) may be directly adhered to the object to form an image by ink which is then output from the image forming unit 100. ) The base supply unit 105 includes a base in the form of an ink cartridge 70 and is configured to be replaced so that the entire remaining cartridge displayed in the ink remaining amount panel 60 can be replaced in accordance with the notification of replacement time, or It is configured in such a manner as to charge the base, such as ink filling in a printing apparatus which is widely used. The base supplied from the base supply unit 105 is basically determined by a value set to match the width of the output unit 90, but when the output is to be reduced in size, the output unit is adapted to the width of the reduced image. The base is provided with a width narrower than the width of 90. In addition, when the outer line of the image has a variety of shapes according to the shape of the curve or the image, not a straight line, various types of bases are provided according to the shape of the image.

The image forming unit 110 serves to form an image by outputting ink on the base supplied from the base supply unit 105. When an image to be output by the image selection button 20 is selected from the images received from an external device through the USB connection terminal 10 of the portable printing apparatus 100, the image forming unit 110 controls the controller 115. By the control at, the ink is output on the supplied base according to the shape and color of the image to form an image. Therefore, when the controller 115 controls to reduce, enlarge or divide the image to be output, the controller 115 forms a reduced, enlarged or divided image accordingly. In this case, an ink jet method used in a conventional printer is used as a method of outputting ink to form an image. Meanwhile, in one embodiment of the present invention, an ink jet method is used to form an image, but the present invention is not limited thereto, and other image forming methods may be used.

When the image to be output is input, the controller 115 controls the base supply unit 105 to supply the base to the image forming unit 110, and controls the image forming unit 110 to input the image input on the supplied base. Serves to form. In this case, the width of the base supplied from the base supply unit 105 is set in advance to the controller 115 according to the width of the output unit 90, and configured to change the set value. In addition, the controller 115 controls the image forming unit 110 when the image stored in the image storage unit 135 or the image input through the USB connection terminal 10 is to be reduced, enlarged or divided. As a result, the image to be output on the base supplied by the base supply unit 105 is reduced or enlarged. In addition, the controller 115 outputs an image with a width wider than that of the image formed by the image forming unit 110, that is, the input image is larger than the width of the output unit 90 of the portable printing apparatus 100. When the output is to be performed in width, the image is divided into a predetermined size, the coordinates of the divided image are stored, and each image separated by each coordinate is provided to the image forming unit 110 to provide the divided images. To form. In this case, when the user uses the portable printing apparatus 100 by determining the order of the images to be formed in the image forming unit 110 in advance and outputting the images according to the order, the divided images are immediately outputted in order. You can do it. The processing of such an image, when the user is attached to the object to be output through the output preview panel 50 to the object on the basis of the output unit 90, because it can be known in advance in what size or width, According to the selection, it is possible to determine an image processing type such as enlargement, reduction, and division of an image. The method of selecting the image processing form and controlling the control unit 115 according to the present invention is embedded in the control unit 115 in the form of a program so that the selectable processing form is displayed on the display unit 130 when the portable printing apparatus 100 operates. Will appear.

In addition, the controller 150 includes a speed sensor 160 that detects a moving speed of the portable printing apparatus 100, and controls the image forming unit 110 to form an image based on the speed measured by the speed sensor. When the user uses the portable printing apparatus 100, the speed of dragging the apparatus for outputting an image to an object is different for each user, so that the user may use the image forming unit according to the speed of using the portable printing apparatus 100. 110) to form an image. If the image is not formed according to the user's moving speed, the part that does not follow the user's speed of use of the device may appear blank because the image has not been formed yet, so the correct image cannot be output.

The protective film providing unit 120 serves to provide a film for preventing damage to an image formed on the base. Once the image is formed on the base through the image forming unit 110, the image may be damaged depending on what the main purpose of the attached object is or what the use environment is. For example, if an image is attached to the outside of an object used in outdoor activities such as a wet bathroom or a car or a motorcycle, the image may be damaged and it may be difficult to preserve the original shape. In addition, even if the decoration of the indoor items, such as dust may be sitting, or the image may be damaged by cleaning, such as to protect the protective film on the image formed on the base for protection purposes to prevent this. As a film used therein, for example, a transparent fluoropolymer film may be used. Due to its excellent chemical resistance and weathering property, the fluoropolymer film may protect the substrate having low durability from external and internal use from damage. Thus a transparent fluoropolymer film is used to protect the image formed on the base. The protective film is stored in the protective film providing unit 120 in the form of a roll, and when the base on which the image is formed is outputted together with the image, the protective film is protected from the factors such as moisture or dust. . In order to attach the protective film to the base on which the image is formed, the heat applied from the drying unit 125 and the pressure applied to the object applied for output from the image output unit 155 are used. Therefore, the protective film is coated on the base on which the image is formed, and the effect can be prevented from being damaged by moisture or other factors.

The drying unit 125 serves to help dry the image formed on the base and attach the base or the film to the object. The drying unit 125 may quickly dry the ink constituting the image formed on the base by providing hot air, or increase the adhesive strength of the base, and as described above, the protective film provided by the protective film providing unit 120. This will help to attach well to the image or to the object. The drying unit 125 is configured by a hot wire similar to the driving principle of a general hair dryer, or by a structure of a hot wire and a fan to provide heated warm wind, that is, hot air.

The display unit 130 serves to display at least one of the remaining amounts of the base and the ink, the target image to be output, the current output state, and the output progress rate. This is subdivided into an output image summary information display unit 30, an output progress display unit 40, an output preview panel 50, an ink remaining amount panel 60, and the like shown in FIG. In addition, when the image forming unit 110 divides the input image according to the image segmentation by the controller 115, the display unit 130 divides the output image formed by the divided image, the number of images to be totally output, and is currently being output. At least one of the number of the image and the number of remaining images waiting to be displayed is displayed.

The image storage unit 135 serves to store the received image. The image input to the portable printing apparatus 100 through an external PC or an image device through the USB connection terminal 10 is stored in the image storage unit 135, and when the image is determined as an output object according to the user's selection, the image is displayed. It is used when forming.

The output guide unit 140 serves to provide a guideline for guiding the formed image to a predetermined position of the object. The output guide unit 140 outputs light of a predetermined color (for example, red or green) along the outer line or the center of the formed image to induce a position at which the image is output from the object. By the output induction guide 80. The image formed in the image forming unit 110 and output through the image output unit 155 is limited by the width of the image output unit 155 in the width, but there is almost no limitation in the length. Therefore, when the long image is output from the portable printing apparatus 100, it is not easy to directly output the first starting point and the ending point of the image. In this case, when the user moves the portable printing apparatus 100 by hand, the user may move the image along the guide line output in the form of light by the output guide unit 140 so that the image is output at the correct position. .

The reduction unit 145 detects a moving speed of the portable printing apparatus 100, and controls the moving speed of the portable printing apparatus to be less than or equal to the preset speed when the portable printing apparatus is moved beyond the preset speed. This is a part that performs a function similar to the device driving speed control using the speed sensor 160 in the control unit 115, and unlike the control unit 115, the image forming unit 110 of the portable printing apparatus 100 displays an image. When the moving speed of the printing device 100 is faster than the time required for forming, the printing device 100 is fixed by a mechanical configuration such as a bearing or a spring so that the printing device 100 can no longer be dragged downward. Control below the set speed. Here, the preset speed refers to a maximum speed at which the image forming unit 110 outputs ink to form an image properly. In the portable printing apparatus 100, a problem in which the moving speed of the device becomes slower than the time for forming the image is adjusted to the moving speed or the image is not yet formed in the image storage unit 135. This can be solved by storing the information. However, since the image forming speed in the image forming unit 110 is limited when the driving speed of the printing apparatus 100 is fast, the printing apparatus 100 is controlled through the reduction unit 145 to control the device speed in proportion thereto. Will control the speed of movement.

The warning sound generator 150 may generate a warning sound when the speed of the portable printing device measured by the speed sensor 160 is faster than the preset speed. In the case of controlling the driving speed of the device by the reduction unit 145, when the driving speed is fast, the speed is controlled by fixing the printing device 100 so that it can no longer be dragged downward. However, when the control unit 115 controls the image forming speed of the image forming unit 110 by the speed sensor 160, the image may not be output properly because the image forming speed of the image forming unit 110 is limited. have. Therefore, in order to prevent such a situation from occurring, if the speed of the portable printing apparatus 100 is faster than a preset speed, that is, an average speed capable of forming an image in the image forming unit 110, a warning sound is generated to alert the user. do.

The image output unit 155 serves to output the base on which the image is formed in the image forming unit 110 to the contact surface of the object. At this time, the image output unit 155 includes a pressure sensor 165 that detects whether the object is in contact with the object, and when the contact with the object is detected from the pressure sensor 165, the image forming unit 110 displays the base on which the image is formed. Output to the contact surface of the object. That is, when the image to be output is selected and the image output unit 155 is brought into contact with the surface of the object to be output, the image is directly output even without pressing a separate operation button. In addition, the image output unit 155 may be configured to start the output by pressing the output button 25, for this purpose is first provided with an output button 25 for outputting the base on which the image to be bonded to the object, By sensing the pressing of the button, the image forming unit 110 outputs the base on which the image is formed to the contact surface of the object.

The speed sensor 160 is included in the controller 115 and serves to detect a driving (moving) speed of the portable printing device 100. The speed detected by the speed sensor 160 is used by the controller 115 to stop the driving of the portable printing apparatus 100 or to control the driving speed of the printing apparatus 100 by other methods.

The pressure sensor 165 is included in the image output unit 155 to detect whether the image output unit 155 is in contact with the object. The pressure sensed by the pressure sensor 165 serves to start output of the image formed in place of the output button 25.

As shown in FIG. 5, the method of controlling a portable printing apparatus according to the present invention includes dividing an image based on a preset size (S210), determining an output order (S220), and each divided image. Providing a step (S230).

Step S210 serves to divide the image based on a preset size. The image forming unit 110 divides the image received in step S110 based on the preset size, where the preset size is the width of the output unit 90 of the portable printing apparatus 100 as before. The value is basically set in the image forming unit 110. However, the preset size is not necessarily fixed to one value, but may be a flexible value that can be changed by changing the width setting of the output unit 90 as necessary. For image segmentation, the controller 115 divides an image into a predetermined size, that is, a width of the set output unit 90, stores each coordinate of the divided image for the whole image, and divides each of the images separated by each coordinate. The image is divided by providing the image to the image forming unit 110.

Step S220 serves to determine the output order. This is a process of determining the output order for the divided image in step S210. When the controller 115 appears to have a wide width according to the shape of the image, if the output order is not constant among the divided images, the divided image is subsequently displayed. Because it is difficult to do. Therefore, the controller 115 determines the output order by using the coordinates of the divided images for the entire image stored in step S210. In this case, each coordinate of the divided image mainly uses X-axis coordinates, and the larger the X-axis coordinate value, the later the output order becomes.

Step S230 serves to provide each of the divided images. The controller 115 is a step of providing each of the divided images to the image forming unit 110 in consideration of the output order determined in step S220. Accordingly, the image forming unit 110 sequentially forms the provided images in order of output.

The present invention described above may be variously modified or applied by those skilled in the art, and the scope of the technical idea according to the present invention should be defined by the following claims.
