Description

Braille printer

[0001] The present invention relates to a Braille printer, and more particularly, to a Braille printer that prints information in Braille on Braille paper so that a visually impaired person can read the contents by hand.

[0002] Typically, visually impaired people can only read special outputs printed in Braille using their fingers or other tactile senses. Braille is a character-based format consisting of six dots arranged in two rows and three columns, with a groove cut into the back to allow the dots to protrude toward the front. Braille documents typically contain 32 Braille characters per line. Therefore, a single line can contain a total of 64 dots.

[0003] Existing Braille printers used solenoid actuators, which used solenoid coils and magnets to produce Braille. Each solenoid actuated would produce a Braille character at that location. However, these devices were so noisy that they were only available to professional printers and were not suitable for home use. Furthermore, existing Braille printers were prohibitively expensive, often reaching tens of millions of won, making them unaffordable for the average household.

[0004] In the case of Braille paper, since a strong force must be applied to leave a mark, the stronger the solenoid actuator force, the louder the noise. Therefore, the existing noise problem can be seen as a problem due to the solenoid actuator method. In addition, the solenoid actuator of the existing Braille printer requires a strong force for striking, so it naturally becomes large. Usually, in order to print 64 dots in one line with 13 solenoid actuators, the process of printing Braille while moving sideways must be repeated, which requires a lot of printing time.

[0005] Additionally, there is a disadvantage in that the cost increases significantly because 13 large-capacity solenoid actuators must be installed.

[0006] The present invention has been devised to solve the above-described problems, and provides a Braille printer that can significantly reduce noise compared to existing methods and has a configuration capable of printing 64 dots in a single line at once, thereby printing Braille more efficiently and quickly than existing methods, while significantly reducing the cost.

[0007] An embodiment of the present invention, in order to solve the above-mentioned problem, comprises: a cartridge for controlling the protruding positions of a plurality of tactile pins; a tactile block installed facing the cartridge and having tactile holes formed in a shape of the tactile pins at a portion that comes into contact with the front ends of the tactile pins; a paper supply unit for supplying paper between the cartridge and the tactile block; and a pressing unit for pressing at least one of the cartridge and the tactile block in a direction toward the paper positioned between the cartridge and the tactile block; wherein the cartridge comprises: a tactile pin guide block having guide holes formed therein into which a plurality of the tactile pins are guided so as to be inserted in a row and moved; a tactile pin control bar positioned at the rear ends of at least two of the tactile pins and arranged so as to be moved in a direction crossing the tactile pin guide blocks; And a control bar actuator for controlling the longitudinal position of the dot pin control bar; the dot pin control bar includes a dot pin control unit having a convex portion supporting the rear end of the dot pin along the longitudinal direction, and a concave portion formed therein, providing a braille printer.

[0008] It is preferable that the above-mentioned dot pin control bar further include an actuator coupling part that extends to the rear end of the dot pin control part and is coupled with the control bar actuator.

[0009] It is effective that the first control bar guide further includes a plurality of first dot pin mounting portions formed on which the dot pin control bar can be mounted, and the adjacent first dot pin mounting portions are formed in opposite directions.

[0010] The second control bar guide is formed by being stacked in a direction away from the tactile block on the first control bar guide, and has a plurality of second tactile pin mounting portions formed thereon; and the tactile pins include a first tactile pin supported by the tactile pin control bar mounted on the first control bar guide; and a second tactile pin supported by the tactile pin control bar mounted on the second control bar guide; and it is effective that the second tactile pin is formed longer than the first tactile pin.

[0011] It is preferable that the first dot pin and the second dot pin are arranged alternately in a bundle.

[0012] It is effective that the control bar actuator of the first control bar guide is installed on the side facing the tactile block, and that the control bar actuator of the second control bar guide is installed on the opposite side of the side facing the tactile block.

[0013] It is preferable that the plurality of convex portions corresponding to one of the above-mentioned dot pins are formed by being continuously connected along the longitudinal direction.

[0014] It is effective that the cartridge is positioned on the upper side of the tactile block, and the compression part is positioned on the upper side of the cartridge.

[0015] According to the problem-solving means of the present invention as discussed above, various effects, including the following, can be expected. However, the present invention is not established only if it exhibits all of the following effects.

[0016] The Braille printer of the embodiment of the present invention can simultaneously control 64 Braille pins forming one line in a Braille document, thereby outputting Braille in one line at the same time, and thus has a very fast printing speed.

[0017] Since it simultaneously outputs a single line of Braille using the force applied by the linear actuator of the compression unit and the load of the cartridge itself, it has the advantage of significantly reducing the cost and producing very little noise.

[0034] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0035] FIG. 1 is a right perspective view of a Braille printer according to an embodiment of the present invention, FIG. 2 is a left perspective view of FIG. 1, and FIG. 3 is a perspective view of a Braille block of FIG. 1.

[0036] As illustrated in FIG. 1, a Braille printer according to an embodiment of the present invention includes a cartridge (1000) for controlling the protruding positions of a plurality of Braille pins (1600) on a main body frame (11, 12), a Braille block (100) which is installed facing the cartridge (1000) and has a Braille hole (110) formed in a shape of the Braille pin (1600) at a portion that comes into contact with the front end of the Braille pin (1600), a paper supply unit (200) for supplying paper between the cartridge (1000) and the Braille block (100), and a pressing unit (300) for pressing at least one of the cartridge (1000) and the Braille block (100) in a direction toward the paper positioned between the cartridge (1000) and the Braille block (100).

[0037] The frame (11, 12) includes a horizontal frame (12) supported on the floor and a vertical frame (11) installed vertically on the horizontal frame (12). A tactile block (100) is located on the lower side of the vertical frame (11). A paper supply unit (200) is installed horizontally with respect to the tactile block (100) to supply tactile paper to the upper side of the tactile block (100), a cartridge (1000) is located on the upper side of the tactile block (100), and a pressing unit (300) is located on the upper side of the cartridge (1000). That is, the paper supply unit (200) is installed on the horizontal frame (12), and the tactile block (100), cartridge (1000), and pressing unit (300) are installed from the lower side of the vertical frame (11). A guide rail (13) is installed on the inner side of the vertical frame (11) to guide the cartridge (1000). The frames (11, 12) are formed of a metal frame that can withstand the strong force generated when stamping Braille. A component commonly referred to as an LM guide is used as the guide rail (13).

[0038] The paper supply unit (200) stores Braille paper and supplies only one sheet of paper during printing. The paper supply unit (200) includes a paper pickup unit (210) that picks up one sheet at a time from a paper storage tray (213), and a paper transport unit (220) that transports the paper picked up by the paper pickup unit (210) to the top of the Braille block (100) one line at a time. The paper pickup unit (210) includes a paper storage tray (213) that stores Braille paper, a paper supply motor (211) that is a stepping motor and is positioned at the top of one side of the paper storage tray (213), and a paper pickup roller (212) made of rubber that has a motor shaft of the paper supply motor (211). When the paper supply motor (211) rotates, the paper pickup roller (212) transports only the top sheet of paper one sheet at a time to the paper transport unit (220). The paper transport unit (220) serves to transport the received paper line by line more precisely. The paper transport unit (220) includes a paper transport motor (221) that can precisely transport Braille paper according to Braille specifications using a stepping motor, and a transport roller (222) that is installed on the motor shaft of the paper transport motor (221) and is made of sponge material.

[0039] The compression unit (300) has one end fixed to the upper end of the vertical frame (11) and the other end fixed to the upper end of the cartridge (1000). The compression unit (300) uses a geared motor type linear actuator. The compression unit (300) includes a compression unit body (310) in which a motor and a gear are built in, and a cylinder (320) that can be extended or shortened in the compression unit body (310). As a result, when the cylinder (320) is extended, the cartridge (1000) descends toward the tactile block (100), and when it is shortened, the cartridge (1000) moves away from the tactile block (100).

[0040] The Braille block (100) is formed by having Braille holes (110) penetrate the upper surface. The Braille holes (110) are grouped in pairs, and a total of 64 Braille holes (110) are formed by having Braille pins (1600) penetrate the Braille holes (110). Since Braille should be formed by inserting Braille pins (1600) while paper is positioned at the top, the Braille holes (110) should have a 1:1 correspondence with the Braille pins (1600) and should be formed in a shape in which a groove is dug to match the shape in which the Braille pins (1600) protrude. In addition, the Braille holes (110) should be positioned exactly concentrically with the Braille pins (1600). The Braille block (100) is fixed at both ends to frames (11, 12).

[0041] Figure 4 is a perspective view of the cartridge of Figure 1.

[0042] The above cartridge (1000) comprises a dot pin guide block (1100) in which a guide hole (1110) is formed so that a plurality of the dot pins (1600) are inserted in a row and guided so that they can move, a dot pin control bar (1200) positioned at the rear end of at least two of the dot pins (1600) so as to be able to move in a direction crossing the dot pin guide block (1100), a control bar actuator (1300) that controls the longitudinal position of the dot pin control bar (1200), a first control bar guide (1400) in which a plurality of first dot pin mounting portions (1410) on which the dot pin control bar (1200) can be mounted are formed, and a plurality of second dot pins are formed by being stacked on the first control bar guide (1400) in a direction away from the dot block (100). It includes a second control bar guide (1500) in which a fixing portion (1510) is formed, and a paper detection portion (not shown) installed on the lower surface of the cartridge (1000).

[0043] The paper detector is located at the bottom of the cartridge, more precisely near the paper outlet. It transmits infrared rays and determines the presence of Braille paper based on the amount received. The detection value is then transmitted to the main controller.

[0044] The cartridge (1000) has a dot pin guide block (1100) positioned from the bottom, and a first control bar guide (1400) and a second control bar guide (1500) are arranged above the guide block (1100). A cylinder coupling portion (1710) is formed on the upper side of the second control bar guide (1500) to which the end of the cylinder (320) of the compression portion (300) is coupled, and rail coupling portions (1720) that are coupled to the guide rail (13) and can slide are formed on both sides.

[0045] Fig. 5 is a perspective view of the dot pin guide block of Fig. 4, Fig. 6 is a plan view of Fig. 5, Fig. 7 is a perspective view of the dot pin guide block of Fig. 5 with dot pins arranged, and Fig. 8 is a cross-sectional view taken along the cutting line VII-VII of Fig. 7.

[0046] The dot pin guide block (1100) includes a bottom plate (1120) in which a guide hole (1110) is formed, and a side surface (1130) that protrudes upward from the bottom plate (1120) to protect the dot pin (1600). The guide hole (1110) is formed to align with the dot hole (110) when the dot pin guide block (1100) is fixed to the frame (11, 12).

[0047] The above dot pin (1600) includes a first dot pin (1610) supported by the dot pin control bar (1200) mounted on the first control bar guide (1400), and a second dot pin (1620) supported by the dot pin control bar (1200) mounted on the second control bar guide (1500), and the second dot pin (1620) is formed to be longer than the first dot pin (1610). The first dot pin (1610) and the second dot pin (1620) are arranged in a bundle and alternately. That is, based on Fig. 8, two dot pins (1600) are grouped, and the first dot pin (1610) and the second dot pin (1620) are arranged alternately, so that a total of 64 dot pins are arranged.

[0048] In order to control the adjacently arranged dot pins (1600) like this, the dot pin control bars (1200) for controlling each dot pin (1600) must be arranged very thinly and adjacently, and the actuators for controlling each dot pin control bar (1200) must also be arranged very adjacently. However, it is very difficult to operate reliably when formed like this. In order to resolve this technical difficulty, the embodiment of the present invention implements a dot pin control bar that simultaneously controls a plurality of dot pins (1600) (two in the embodiment of the present invention), and the control bar actuators (1300) for controlling adjacent dot pin control bars (1200) are arranged vertically or front-to-back, thereby operating reliably. This will be examined in more detail below.

[0049] Fig. 9 is a bottom perspective view of the dot pin control bar, Fig. 10 is a right side view of the dot pin control bar of Fig. 9 in a state where the dot pins are in contact with each other, Fig. 11 is an enlarged view of part XI of Fig. 10, and Figs. 12 to 15 are bottom perspective views and planar conceptual diagrams showing the relationship between the dot pins and the dot pin control bar according to their positions.

[0050] As shown in these drawings, the dot pin control bar (1200) includes a dot pin control part (1210) having a convex part (1211) that supports the rear end of the dot pin (1600) along the longitudinal direction, a concave part (1212) formed therein, and an actuator coupling part (1220) that extends to the rear end of the dot pin control part (1210) and is coupled with the control bar actuator (1300).

[0051] The dot pin control bar (1200) of the embodiment of the present invention is formed so as to be able to control two dot pins simultaneously. However, it is not limited to two, and may be formed with three or four dot pins as needed. However, as the number increases, the length of the dot pin control unit (1210) gradually increases, so there is a problem of moving the dot pin control bar (1200) in the longitudinal direction in a short time, and a disadvantage of an increase in size. The following description will be made based on controlling two dot pins (1600) simultaneously.

[0052] The actuator coupling portion (1220) is formed as a rack gear. It is engaged with a pinion gear (1320) formed in a control bar actuator (1300) described later, and its position is controlled by a servo motor (1310).

[0053] The dot pin control unit (1210) is formed by a convex portion (1211) and a concave portion (1212) and an inclined surface connecting them.

[0054] When the dot pin (1600) is engaged with the convex portion (1211), the cartridge (1000) descends, thereby supporting the rear end of the dot pin (1600) so that the dot pin (1600) prints braille on the braille paper. When the dot pin (1600) is positioned in the concave portion (1212), the dot pin (1600) does not print braille on the braille paper. In order to control two dot pins, four combinations of concave portions and convex portions (1211) are required.

[0055] At this time, in order to minimize the slope, that is, in order to minimize the rising and falling position of the dot pin (1600), it is preferable that the plurality of convex portions (1211) corresponding to one dot pin (1600) are formed to be continuously connected along the longitudinal direction. That is, in the planar conceptual diagram of Fig. 12, the convex portions (1211a) that engage with one dot pin (1600) are arranged continuously with each other, and the convex portions (1211b) that engage with another dot pin (1600) are also arranged continuously with each other.

[0056] FIG. 12 illustrates a position where both dot pins (1600) are positioned at the bottom of the concave portion (1212) so that no dot characters are printed, FIG. 13 illustrates a position where the dot pin (1600) positioned on the left is supported by the convex portion (1211) and the dot pin (1600) positioned on the right is supported by the concave portion (1212), so that only the dot characters are printed on the left side, FIG. 14 illustrates a position where both dot pins (1600) are supported by the convex portion (1211), so that two dot characters are printed, and FIG. 15 illustrates a position where the dot pin positioned on the left is positioned on the concave portion (1212), and the dot pin positioned on the right is supported by the convex portion (1211), so that only the dot characters are printed on the right side.

[0057] In this way, by controlling the dot pin control bar (1200) in the longitudinal direction, two dot pins can be controlled simultaneously.

[0058] FIG. 16 is a perspective view showing the first control bar guide of FIG. 4 in a state where the dot pin control bar, the dot pin, and the control bar actuator are combined, FIG. 17 is a perspective view of the first control bar guide of FIG. 16, FIG. 18 is a perspective view showing the second control bar guide of FIG. 4 in a state where the dot pin control bar, the dot pin, and the control bar actuator are combined, and FIG. 19 is a perspective view of the second control bar guide of FIG. 18.

[0059] The control bar actuator (1300) installed in the first control bar guide (1400) and the second control bar guide (1500) includes a servo motor (1310) capable of controlling a position, and a pinion gear (1320) coupled to the shaft of the servo motor (1310). The pinion gear (1320) meshes with a rack gear formed in the actuator coupling portion (1220).

[0060] The first control bar guide (1400) is formed in a plate shape, and a plurality of first pin penetration holes (1420) are formed through which a dot pin can penetrate in the longitudinal direction at the center. A total of 64 first pin penetration holes (1420) are formed through which the dot pin can penetrate, and are formed to match the guide hole (1110) and the dot hole (110). In addition, a first dot pin mounting portion (1410) is formed on the upper side of the first pin penetration hole (1420) so that the dot pin control bar (1200) can be mounted. That is, the first guide protrusions (1411, 1412) protrude so that the dot pin control bar (1200) can be guided when moving in the forward and backward directions, thereby forming the first dot pin mounting portion (1410). These first dot pin mounting portions (1410) are formed eight in each of the front and rear directions. In addition, a first actuator mounting hole (1430) is formed through which a control bar actuator (1300) can be mounted. Eight first actuator mounting holes (1430) are also formed in each of the front and rear directions.

[0061] The adjacent first dot pin mounting portions (1410) are formed in opposite directions. That is, eight first dot pin mounting portions (1410) are respectively arranged in opposite directions between the eight first dot pin mounting portions (1410) located in the front. By arranging them in this manner, it is possible to prevent the control bar actuator (1300) and the dot pin control bar (1200) from interfering with each other as much as possible.

[0062] The control bar actuator (1300) is installed on the surface of the first control bar guide (1400) facing the tactile block (100). That is, the control bar actuator (1300) is installed on the lower surface of the first control bar guide (1400) with reference to FIG. 16.

[0063] The second control bar guide (1500) is formed in a plate shape, and a plurality of second pin penetration holes (1520) are formed through which a dot pin can penetrate in the longitudinal direction at the center. A total of 64 second pin penetration holes (1520) are formed and are formed to match the guide hole (1110) and the dot hole (110). In addition, a second dot pin mounting portion (1510) is formed on the lower side of the second pin penetration hole (1420) so that the dot pin control bar (1200) can be mounted. That is, the second guide protrusions (1511, 1512) protrude so that the dot pin control bar (1200) can be guided when moving in the forward and backward directions, thereby forming the second dot pin mounting portion (1510). These second dot pin mounting portions (1510) are formed eight in each of the front and rear directions. In addition, a second actuator mounting hole (1530) is formed through which the control bar actuator (1300) can be mounted. Eight second actuator mounting holes (1530) are also formed in each of the front and rear directions.

[0064] The adjacent second dot pin mounting portions (1510) are formed in opposite directions. That is, eight second dot pin mounting portions (1510) are respectively arranged in opposite directions between the eight second dot pin mounting portions (1510) located in the front. By arranging them in this manner, it is possible to prevent the control bar actuator (1300) and the dot pin control bar (1200) from interfering with each other as much as possible.

[0065] The control bar actuator (1300) of the second control bar guide (1500) is installed on the opposite side of the side facing the tactile block (100). That is, the control bar actuator (1300) is installed on the upper surface of the second control bar guide (1500) with reference to FIG. 18.

[0066] Although not shown separately, the Braille printer of one embodiment of the present invention includes a controller. The controller includes a main controller and two slave controllers, for a total of three controllers. The main controller is responsible for wired and wireless communication with a computer, and for controlling the paper supply motor (211) and paper transport motor (221) of the paper supply unit and transport unit, and the linear actuator of the cartridge pressing unit (300), and receives signals from the infrared sensor of the paper detection unit. The slave controllers are located one at the front and the rear of the cartridge, and control the control bar actuator (1300) while communicating with the main controller. In addition, there is a power supply capable of stably supplying power, and it is fixed to the frame (11, 12).

[0067] As described above, the cartridge (1000) of the embodiment of the present invention groups two dot pins (1600) and controls them with one dot pin control bar (1200), and adjacent dot pin groups are alternately distributed by the first control bar guide (1400) and the second control bar guide (1500) arranged vertically, and even within the same control bar guide, adjacent dot pin control bars (1200) are arranged to alternately move back and forth. Therefore, sufficient space can be secured for arranging a control bar actuator (1300) for driving one control bar. As a result, 64 dot pins (1600) forming one line can be controlled simultaneously.

[0068] In addition, since the direction in which the control bar actuator (1300) is installed in the first control bar guide (1400) and the second control bar guide (1500) is formed on the opposite side of the facing sides of each other, the first control bar guide (1400) and the second control bar guide (1500) can be installed as close as possible, and as a result, the difference in length between the first dot pin (1610) and the second dot pin (1620) can be minimized.

[0069] The overall operation of the Braille printer is described below.

[0070] When Braille data to be printed is transmitted to the main controller, the paper supply unit (200) feeds the paper one line at a time toward the upper side of the Braille block (100). At this time, the control bar actuator (1300) is controlled to drive the Braille pin control bar (1200) so that the convex portion (1211) can be positioned at the rear end of the Braille pin (1600) at the location where the Braille is to be printed. Then, the compression unit (300) is driven so that the cartridge (1000) descends and the Braille pin (1600) supported by the convex portion (1211) forms Braille on the Braille paper.

[0071] As described above, the Braille printer of the embodiment of the present invention can simultaneously control 64 Braille pins forming a line in a Braille document, thereby simultaneously outputting Braille on a single line, resulting in a very fast printing speed. Compared to conventional Braille printers, conventional Braille printers have the disadvantage of being very slow because they require up to five Braille stamping steps to print a single line of a document.

[0072] In addition, since in the past, only the power of a solenoid actuator was used to apply pressure to form Braille on paper, the capacity of the solenoid actuator had to be large, which made it expensive and very noisy, making it impossible to use for home use. However, the control bar actuator (1300) of the present invention requires only the capacity to drive the Braille pin control bar (1200), and outputs one line of Braille simultaneously by utilizing the force applied by the linear actuator of the pressing unit (300) and the load of the cartridge (1000) itself, so the cost is greatly reduced and there are advantages in that the noise is very low.

[0073] In fact, the noise level of conventional Braille printers is over 80dB, but in the case of the present invention, the noise level is reduced to 50dB, so even when installed and used in general homes, schools, and public institutions, there is no problem of noise interfering with other work.

[0074] Although the preferred embodiments of the present invention have been described above as examples, the scope of the present invention is not limited to these specific embodiments, and may be appropriately modified within the scope described in the claims.
