The present invention relates to a braille pattern forming device.

In general, a printing device is an office device that is connected to a computer and outputs results on printing paper. It receives documents or image data written or edited by the computer, converts them into a printing language suitable for the set printing conditions, and uses ink, toner, etc. This is a device that prints on paper using colored dyes.

Recently, due to the complexity of the office environment and the increasing distribution of office equipment and personal computers essential to the office environment, the office environment is gradually changing into a networking environment, connecting multiple personal computers in the office to a single network network to share the data of each personal computer.

The upper and lower cylinders 160, together with the height adjustment block B, enable the upper wheel 210 to move up and down, allowing the gap between the upper wheel 210 and the lower wheel 220 to be finely adjusted.

More specifically, the upper and lower cylinders 160 are coupled to the upper central axis 140 through a connecting member to directly move the upper wheel 210 up and down.

Here, the height adjustment block (B) is located at the lower part of the upper and lower cylinders 160 and is formed in a rectangular shape so that one surface can be coupled to the upper part of the pair of support plates 111 and 112. That is, the height adjustment block (B) is fixed to a specific position through a coupling member such as a bolt, so that the movement limit of the upper and lower cylinders 160 can be set.

That is, if the upper and lower cylinders 160 allow the vertical positions of the upper central axis 140 and the upper wheel 210 to be adjusted in large units, the height adjustment block B is an adjustment hole on the movement path of the upper and lower cylinders 160. By being coupled to a specific point (not shown), the vertical movement of the upper and lower cylinders 160 is suppressed to enable position adjustment in small units.

The lower wheel 220 may be configured as a rotatable roller coupled to the lower central axis 150.

The Braille panel (Embossing plate) 250 is rolled into a circle, and one end and the other end are bent inward, and a bent portion 251 is seated in the coupling groove 215, and the bent portion 251 has the coupling groove 251. A fixing hole 2515 is formed to correspond to the three pairs of coupling holes 2152 of the groove 215, and is coupled to the outer peripheral surface of the upper wheel 210 to adhere to the printed matter, and a protrusion 252 is formed on the surface. Braille can be printed on the printed matter.

That is, the Braille panel 250 is coupled to the outer peripheral surface of the upper wheel 210 and rotates according to the rotation of the upper wheel 210 to print Braille on the printed matter. This Braille panel 250 can be easily attached and detached by separating and combining the coupling member 260, so of course, various braille patterns that can be printed are possible.

Here, the coupling groove 215 may further include three pairs of coupling holes 2152 and two bolt holes 2154.

The three pairs of coupling holes 2152 may be formed vertically on both sides of the groove to allow the three pairs of fixing protrusions 261 to move up and down.

Two bolt holes 2154 may be formed at both ends of the center of the groove.

The coupling member 260 is formed in a tapered shape and can be inserted into the coupling groove 215 to couple the Braille panel 250 to the upper wheel 210.

The coupling member 260 may further include three pairs of fixing protrusions 261 and bolting portions 262.

Three pairs of fixing protrusions 261 may be formed on the left and right sides of the coupling member 260 to be fitted into the three pairs of coupling holes 2152. In more detail, the three pairs of fixing protrusions 261 may be formed in a circular shape like the coupling protrusions of Lego, and may be fitted into the three pairs of coupling holes 2152 and move up and down.

The bolting portion 262 may be formed to correspond to the two bolt holes 2154. That is, the diameter of the two bolt holes 2154 may be formed to a size that allows bolts to pass through both ends of the upper surface of the coupling member 260.

Looking specifically at the action and effect of coupling the Braille panel 250 to the coupling groove 215 through the coupling member 260, the Braille panel 250 is coupled to the outer peripheral surface of the upper wheel 210, and the Braille panel ( The bent portion 251 of the upper wheel 210 can be seated and fitted into the left and right sides of the coupling groove 215 of the upper wheel 210, and the coupling member 260 has a tapered shape corresponding to the shape of the coupling groove 215. ) can be additionally connected from top to bottom.

Thereafter, the coupling member 260 and the upper wheel 210 are directly coupled to the bolting portion 262 through bolts, and depending on the degree of tightening of the bolts, the three pairs of fixing protrusions 261 are formed into three pairs of coupling holes. It flows up and down at 2152, and the degree of adhesion to the upper wheel 210 of the Braille panel 250 can be adjusted depending on the degree of tightness.

That is, the printed matter is pressed in the process of passing between the upper wheel 210 and the lower wheel 220, and at this time, Braille is printed on the surface of the printed matter by the protrusions 252 formed on the surface of the Braille panel 250. will be. At this time, the clarity of braille printing may vary depending on the degree of adhesion to the upper wheel 210 of the braille panel 250. Therefore, it can be effective in maintaining the best printing quality by finely adjusting the adhesion of the Braille panel 250 through the configuration of the coupling member 260 as described above to maintain optimal adhesion according to the diversity of Braille patterns. .

Meanwhile, the Braille adapter 270 may be coupled to the outer peripheral surface of the lower wheel 220. In more detail, the braille adapter 270 is attached to the protrusion 252 when the printed matter is pressed by the protrusion 252 of the braille panel 250 between the upper wheel 210 and the lower wheel 220. It may include a corresponding Braille forming hole 272 that forms a space in which the Braille will be formed.

The braille forming hole 272 may be a hole recessed in the surface of the braille adapter 270 corresponding to the position of the protrusion 252 of the braille panel 250. Due to the presence of the braille forming hole 272, more space is formed where the braille can be pressed compared to the flat lower wheel 220, and thus the braille can be printed more effectively and clearly.

The upper wheel 310 according to another embodiment of the present invention has a braille pin hole 311 into which the braille pin 320 can be inserted on the outer peripheral surface of the upper wheel 310, and the braille pin 320 is inserted before printing. can be inserted into the braille pin hole 311 to form a braille pattern of a desired shape.

After forming a braille pattern of the desired shape, the braille pin cover 330 with a hole corresponding to the braille pin hole 311 can be mounted through the coupling member 260.

Here, since the method and effect of coupling the braille pin cover 330 by the coupling member 260 are the same, detailed description will be omitted.

In this way, when the braille pin 320 is inserted into the upper wheel 310 itself to form a braille pattern of a desired shape, the braille pattern formation is completed by inserting the braille pin 320, so the braille panel 250 is divided into braille patterns for each braille pattern. Since only one braille pin cover 330 is required, unlike the need for multiple braille pin covers, it can be more efficient in printing by forming various braille patterns. In other words, this embodiment may be suitable for printing jobs of small quantities and various types.

After insertion, the coupling means 835 with a coupling cap 835a added to the upper part is fastened. In addition, a fine gap is formed between the support body 840 and the through hole 831, and the gap D is maintained on the bottom of the coupling cap 835a constituting the vibration damping body 810 and the coupling means 835.

It can be absorbed through In more detail, the vibration generated as the vibration damping body 810 moves up and down is absorbed by the elastic means 820 coupled to the protrusion 834 added to the bottom of the support plate 830. Additionally, left/right tremors can be absorbed by the gap D formed between the support 840 and the through hole 831. In this way, all vibrations or shocks generated from the vibration damping body 810 are blocked and absorbed or attenuated before they are transmitted to the floor plate 850, thereby completely eliminating noise generated during the operation of the left and right drive motors 180.
