Description

Printing device and control method of printing device

Embodiments of the present invention relate to a printing apparatus and a control method of the printing apparatus, and in more detail, it is possible to smoothly transport a to-be-printed object, and to prevent a jam phenomenon of the to-be-printed material generated when the to-be-printed material is transported. It relates to a printing device that can be easily held in place.

In general, a printing apparatus is one of output apparatuses for printing characters or figures on the surface of a printed object. The to-be-printed object may be formed of paper, synthetic resin, fabric, or the like, and may be formed of various materials and shapes according to industrial fields and purposes for which a printing apparatus is used. For example, printed matters used in the field of financial automation equipment include bank accounts, receipts, and slips formed of paper media.

On the other hand, in the printing apparatus according to the prior art, a jam phenomenon in which the to-be-printed object is caught on a conveyance path during the transfer of the to-be-printed object may occur. That is, although a hole for arranging a print unit or another device may be formed in the transfer passage of the printing apparatus, when the to-be-printed object is transferred along the transfer passage, the to-be-printed object may be jammed to the hole part. .

In addition, the print unit of the printing apparatus according to the prior art employs a separate positioning sensor for determining the exact position of the print head since the print head starts printing at the correct position in order to increase printing accuracy. However, in this case, there is a problem in that the structure of the printing apparatus becomes complicated and the production cost increases.

In addition, the printing apparatus according to the prior art, since the position of the transfer unit for transporting the to-be-printed object varies according to the thickness of the to-be-printed object, the position change of the transfer unit is sufficiently compensated, and the driving force is applied to the transfer unit. It requires a driving force transmission structure that can deliver smoothly.

On the other hand, the transfer unit of the printing apparatus according to the prior art, as well as a plurality of rollers and belts for transferring the to-be-printed body is equipped with a separate electric pulley and a transmission belt for transmitting power to the rollers. Therefore, the printing apparatus has an increased working time for mounting the electric belt and the electric pulley, and because the electric belt and the roller are separately mounted on the printing apparatus, the structure becomes complicated and the volume also increases.

Embodiments of the present invention provide a printing apparatus and a control method of the printing apparatus that can prevent a jam phenomenon of the printed matter generated when the printed matter is transferred.

In addition, an embodiment of the present invention provides a printing apparatus and a control method of the printing apparatus that can easily eliminate the jam phenomenon of the printed matter with a simple structure and low cost.

Further, an embodiment of the present invention provides a printing apparatus and a control method of the printing apparatus that can more accurately read information of a magnetic strip formed on a printed object.

Further, an embodiment of the present invention provides a printing apparatus and a control method of the printing apparatus that can easily determine the exact position of the print head in a mechanical manner.

In addition, embodiments of the present invention, it is possible to simplify the structure and size of the transfer unit, to simplify the power transmission structure, and to provide a printing apparatus and a control method of the printing apparatus that can improve the transfer performance of the to-be-printed object. do.

In addition, an embodiment of the present invention provides a printing apparatus capable of smoothly transmitting a driving force to a transfer unit for transferring a to-be-printed object.

In addition, the embodiment of the present invention, it is possible to compensate for the positional change of the transfer unit according to the thickness of the to-be-printed object, and to provide a printing apparatus capable of preventing the deterioration of the transfer performance of the driving force due to the positional change of the transfer unit.

According to an embodiment of the present invention, a casing having a conveyance passage for transferring a book-shaped object to be conveyed, a conveying unit for transferring the object to the page turning hole formed in the conveying passage, the casing is provided in the casing Provided is a printing apparatus including a medium turning unit for turning over the print sheet of the to-be-printed object disposed in the and a number detecting unit provided in the medium turning unit and detecting the number of sheets of the printed sheet turned over by the medium turning unit. The media turning unit may include a media turning mode in which the printing sheet is turned from one side of the to-be-printed side to the other side, and when the printed sheets of the to-be-printed sheet are sensed in plural by the number sensing unit, A media separation mode for separating the print sheets at a position where the number of sheets of print sheets is sensed is performed.

That is, in the media flipping mode, the media flipping unit may flip the print sheet of the to-be-printed sheet by sheet. In the medium separation mode, when a plurality of sheets of printing sheets turned over by the media turning unit are detected by the number detecting unit, the media turning unit may separate the turned sheets. Therefore, the printing apparatus can turn the pages of the to-be-printed correctly one by one by the media turning unit.

In addition, since the media flipping mode and the media separation mode are performed in different ways, the plurality of sheets of print sheets passed in the media flipping mode can be separated more smoothly in the media separation mode. If the media turn over mode and the media separation mode are performed in the same manner, the print sheets may be turned over without being separated to one side of the to-be-printed body in the same process as the print sheets are turned over. That is, in the present embodiment, by separating the media turning mode and the media separation mode of the media turning unit in a different manner, the separation performance of the printing sheets by the media turning unit can be improved. And the page turning performance of the printing apparatus can be significantly improved.

The media turning unit may include a first end rotatably provided in the casing and disposed between the first position contacting one surface of the printed sheet of the printed object disposed on the page turning hole and the second position contacting the other surface of the flipped printing sheet. It may include a arm portion pivoted from, and a roller portion rotatably provided at the other end of the arm portion and the printing sheet of the to-be-printed object.

In the media turning mode, the arm part may be disposed at a first position to contact the roller part with one surface of a printing sheet of the to-be-printed object. In addition, the roller unit may be rotated in a direction of passing the printing sheet of the to-be-printed object from one side to the other side of the to-be-printed object. Therefore, the printing sheet disposed on one side of the to-be-printed object may be turned over to the other side of the to-be-printed object by the rotational force of the roller part.

In the media separation mode, the arm portion may be disposed at a second position to contact the roller portion to the back surface of the printed sheet. In addition, the roller unit may be rotated in a direction to return the flipped printing sheets to one side of the to-be-printed object. Therefore, the transferred printing sheets may be partially separated to one side of the to-be-printed object by the rotational force of the roller unit.

The media turning unit may further include a support part disposed to face the roller part at a second position of the arm part and supporting one surface of the turned over printing sheet. In the medium separation mode, the turned over printing sheet may be disposed between the support part and the roller part. Therefore, the turned over printing sheet may not only be stably disposed in a structure sandwiched between the support part and the roller part, but also the media separation mode of the media turning unit and the number sensing operation of the number sensing unit may be stably performed. have.

The roller portion overlaps the conveying surface of the conveying passage at the first position of the arm portion and overlaps the support portion at the second position of the arm portion. Therefore, a part of the roller portion may be in close contact with the printing sheet of the to-be-printed object or the printing sheet turned over by the roller portion. Therefore, the roller part can improve the performance of picking up the printing sheet of the to-be-printed object.

The roller portion may be provided with a plurality of spaced apart from the other end of the arm portion. The support portion may be provided in a plurality of spaced apart from the casing. The support parts and the roller parts may be staggered from each other. That is, the support parts and the roller parts may be overlapped with each other and staggered with each other. Therefore, a printing sheet can be more stably disposed between the supporting portions and the roller portions.

For example, when the arm portion is disposed on the turned over printing sheet, the turned over printing sheet is disposed between the roller portions and the supporting portions, and thus is bent several times in a staggered direction of the roller portions and the supporting portions. It can be arranged as. Thus, the flipped printing sheet may be structurally enhanced in an uncurved direction.

One side of the roller portion may be formed to protrude more than the other portion with respect to the rotation center. One side of the roller portion may be provided with a pad formed of a rubber material. A plurality of anti-slip grooves may be formed spaced apart from the contact surface of the pad.

Here, the pad of the roller unit performs a pick-up function of turning over the printing sheet from one side of the to-be-printed object or separating the transferred print sheets to one side of the to-be-printed object. In addition, when the pad is formed of a rubber material and anti-slip grooves are formed on the contact surface of the pad, the friction coefficient between the pad and the printing sheet is increased, so that the pick-up performance of the roller may be improved.

For example, the roller portion may be formed in an elliptic shape, and the pad may be provided in at least one of the long radius portions of the roller portion. Therefore, when the roller portion is rotated, a portion where the pad of the roller portion is formed and a portion where the pad is not formed may be continuously switched on the surface of the printing sheet.

In addition, the long radius of the roller portion may be formed in such a length that the transfer surface of the transfer passage and the pad overlap with each other when the printing sheet is turned over, and at the same time, the length of the support portion and the pad overlap when the printed sheet is separated. It can be formed as. On the other hand, in the short radius of the roller portion, the pad unformed portion of the roller portion may be disposed above the conveying surface of the conveying passage when the printing sheet is turned over, and at the same time, the pad portion of the roller portion is not formed when the printed sheet is separated. The site may be formed to a length that does not overlap with the support.

Meanwhile, when the transfer unit is operated, the short radius portion of the roller portion may be disposed to face the page turning hole portion. That is, the roller portion and the to-be-printed object may be disposed so as not to interfere with each other when the transfer unit is operated, whereby the to-be-printed material can be smoothly conveyed along the conveying passage.

A page turning hole may be formed at an upper portion of the transfer passage so that the print sheet of the to-be-printed object can be turned over. Accordingly, the arm portion and the roller portion are disposed above the conveyance passage, and the turning of the paper medium of the to-be-printed object may be performed through the page turning hole.

The lower portion of the transfer passage may be formed with a depression recessed downward in a position facing the page turning hole. The depression may be formed deeper than the length of the transfer surface and the roller portion of the transfer passage overlap. That is, when the end portion of the arm portion is disposed in the page turning hole, the pad may be in close contact with one side of the to-be-printed portion as the roller portion is rotated, and one side of the to-be-printed portion may be bent into the recessed portion. have. As described above, when one side of the to-be-printed object is in close contact with the pad, the contact force between one side of the to-be-printed object and the pad may be increased. Therefore, the printing sheet can be picked up more smoothly from one side of the to-be-printed object when the roller part rotates.

The media turning unit may further include a shutter provided on the conveyance passage to close the page turning hole and to open the page turning hole when turning the page of the roller. Accordingly, when the to-be-printed object is transferred, the shutter unit closes the page turning hole, thereby preventing a jam phenomenon in which the to-be-printed object interferes with the page turning hole. In addition, since the shutter unit opens the page turning hole part when the page of the to-be-printed page turns, the arm part and the roller part may turn over the print sheet of the to-be-printed object without being disturbed by the shutter unit.

The media turning unit may include an arm part rotating shaft rotatably disposed on the casing and rotatably supporting one end of the arm part, a first driving part providing rotational force to the arm part rotating shaft, a second driving part providing rotational force to the arm part; It may further include a power transmission member for the roller unit for receiving the rotational force from the arm rotating shaft to the roller unit, and a power transmission member for the shutter unit for receiving the rotational force from the arm rotating shaft to the shutter. That is, the rotation of the arm part and the arm part may be controlled independently by the first driving part and the second driving part, and the rotational force of the arm part rotating shaft is provided by a roller power transmission member and a shutter power transmission member. It may be transmitted to the roller portion and the shutter portion, respectively.

Herein, the power transmission member for the roller portion may include a first roller portion gear provided on the arm portion rotation shaft, a second roller portion gear provided on the rotation shaft of the roller portion, and the first roller portion gear rotatably provided on the arm portion. At least one third roller unit gear for transmitting a rotational force of the second roller unit gear may be provided. The power transmission member for the shutter unit may be rotatably provided in the first shutter unit gear provided in the arm shaft rotation shaft, the second shutter unit gear provided in the rotation shaft of the shutter unit, and the casing. At least one third shutter unit gear for transmitting a rotational force of the gear to the second shutter unit gear may be provided. Therefore, the roller unit and the shutter unit may be linked by the rotational force of the first driving unit, and a power transmission mechanism of the roller unit and the shutter unit may be simply formed.

The first shutter gear and the arm rotating shaft may include a clutch unit for intermittent rotation force transmitted from the arm rotating shaft to the first shutter gear unit according to whether the shutter unit is restrained. That is, the first shutter gear may be disposed to be idling on the arm rotating shaft, and the clutch unit may be provided between the arm rotating shaft and the first shutter gear. The clutch unit may control the rotational force transmitted from the arm rotating shaft to the first shutter gear according to whether the first shutter gear is restrained, that is, the shutter is locked.

For example, the clutch unit may include a first washer fixed to one side of the arm rotating shaft, a second washer fixed to the other side of the arm rotating shaft so that the first shutter gear is disposed between the first washer, and It may include an elastic member disposed between the second washer and the first shutter gear, and elastically contacting the first washer, the second washer and the first shutter gear. Therefore, since the first shutter gear, the first washer, and the second washer are in close contact with each other by the elastic force of the elastic member, the first shutter gear, the first washer, and the second washer are Can be rotated together.

On the other hand, when the operation of the first shutter gear is constrained by a force greater than the frictional force acting on the contact surfaces of the first shutter gear and the first washer and the second washer, the transmission of the rotational force through the clutch is blocked. Only the arm rotation axis can be rotated. That is, the first shutter gear is maintained in a stopped state, and the second shutter gear and the third shutter gear are also kept in a stopped state together with the first shutter gear.

The second driving part may include a driving gear, and the arm part may include an arm gear coupled to the driving gear. Therefore, the rotational force of the second drive unit may be transmitted to the arm unit through the drive gear and the arm gear, and the arm unit may be pivoted together with the arm gear about the arm rotation axis.

An interference part may be formed at one side of the arm gear so as to interfere with the casing at the second position of the arm part to mechanically set the second position. The other side of the arm gear may be engaged with at least one of the shutter unit or the shutter unit power transmission member at the second position of the arm unit, and a locking unit may be formed to restrain the shutter unit in an open state. That is, when the arm portion is disposed in the second position, the second position can be simply set because the interference portion interferes with the casing, and the locking portion is at least one of the shutter portion or the shutter portion power transmission member. Since it is caught in the shutter portion can be simply restrained in the open state.

First and second avoidance grooves may be formed in the shutter unit. The first avoiding groove may be formed at a position corresponding to the roller part so as to prevent interference between the roller part and the shutter part. The second avoiding groove may be formed at a position corresponding to the support so as to prevent interference between the support and the shutter. Therefore, the roller portion and the arm portion can be smoothly operated without interfering with the shutter portion during the operation of the printing apparatus.

The roller portion may be formed with a first positioning projection for setting the closed position of the shutter unit. The first positioning protrusion may interfere with the shutter unit at the first position of the arm unit. Therefore, since the first positioning projection limits the opening and closing operation of the shutter unit, it is possible to prevent the shutter unit from being arbitrarily operated when transferring the to-be-printed object.

The support portion may be formed with a second positioning projection for setting the open position of the shutter unit. The second positioning protrusion may interfere with the shutter unit at the second position of the arm unit. Therefore, since the second positioning projection limits the maximum rotatable angle of the shutter unit when the page turning hole is opened, the opening position of the shutter unit can be accurately set.

Guide portions for guiding the transfer of the to-be-printed object may be formed at both ends of the other end of the arm. Therefore, when the arm portion is disposed at the first position during the transfer of the to-be-printed object, skew and random detachment of the to-be-printed object can be prevented by the guide portion.

The number detecting unit may detect the number of sheets of printing sheets disposed between the support unit and the roller unit at the second position of the arm unit. That is, the number detecting unit detects the number of printed sheets sandwiched between the support part and the roller part, so that the number of printed sheets can be stably sensed.

The number detecting unit is provided on one side of the media delivery unit, the ultrasonic generator for emitting ultrasonic waves to the printed sheet of the to-be-turned by the roller unit, and the other side of the media delivery unit facing the ultrasonic generator It may be provided to include an ultrasonic sensor for detecting the ultrasonic wave passed through the printing sheet. That is, the number detecting unit may detect the number of sheets of the printing sheet according to the detection value of the ultrasonic waves passing through the printing sheet disposed between the roller unit and the support unit. If there are a plurality of sheets of printed sheets that are passed, gaps exist between the printed sheets, and the gaps modify the waveform of the ultrasonic waves passing through the sheets of printed sheets, and whether the sheets of sheets of printing are passed from the wave of the ultrasonic waves. Or it can be determined whether there are a plurality of sheets.

Here, the ultrasonic generator may be provided in the arm portion, the ultrasonic detector may be provided in the support portion. That is, when the arm part is disposed at the second position, the ultrasound generator and the ultrasound detector may be in focus with each other.

The number sensing unit may further include a dispersion prevention unit provided in at least one of the ultrasonic wave generating unit or the ultrasonic sensing unit to surround a side to prevent dispersion of ultrasonic waves. The dispersion preventing unit may be a tubular member formed to a predetermined length, and may minimize the dispersion of the ultrasonic waves in a portion other than the ultrasonic detection unit, thereby improving the performance of the number detecting unit.

According to another aspect of the present invention, the to-be-printed entry step in which the transfer unit enters the book-shaped to-be-printed object into the arm portion, the arm portion at a first position where the roller portion provided at the end of the arm portion is in contact with the printing sheet of the to-be-printed object. Positioning the first position step, Rotating the roller portion in one direction to turn over the print sheet of the to-be-printed object from one side of the to-be-printed, Rotating the arm portion in one direction to support the flipped printing sheet A second positioning step of positioning the arm portion in a second position facing the roller portion in the support portion, using the ultrasonic generator provided in the arm portion and the ultrasonic sensing unit provided in the support portion for detecting the number of sheets of the printed print sheet If the number of sheets to be printed is detected as a single sheet in the number of sheets detecting step and the number of sheets detecting step, And a to-be-printed discharging step of rotating the base arm in the other direction and discharging the to-be-printed object from the arm to turn the transferred print sheet to the other side of the to-be-printed object.

Therefore, the printing apparatus may not only correctly turn over the print sheet of the to-be-printed object one by one, but also accurately detect the number of sheets of the print sheet to be passed from the to-be-printed object by using an ultrasonic sensor. On the other hand, if the number of sheets of the printing sheet is not detected in the number of detecting step, it may be re-executed from the first position setting step.

In addition, the page turning method of the printing apparatus, when the number of sheets of the printed sheet is detected in the number of sheets detecting step, by rotating the roller unit in the other direction to separate some of the printing sheets from the printed sheets and the separated The method may further include a media separation step of returning a printing sheet to one side of the to-be-printed object. In the media separating step, since the printed sheets are separated in a different manner from the media turning step, the separation performance of the printed sheets may be improved.

When the medium separation step is completed, the number detection step may be performed again. In addition, if the transferred printing sheet is detected as a single purchase in the number of detecting sheets, the discharge of the to-be-printed object may be performed. On the other hand, when the number of sheets of the printed sheets is sensed in the number of sheets detection step, the media separation step may be repeated.

That is, the printing sheets disposed between the roller portion and the support portion may be partially separated in the media separating step and returned to the original position of the to-be-printed object, but the remaining print between the roller portion and the support portion may be used. The sheets may still be plural. Therefore, the medium sensing step is performed again to detect whether there are a plurality of print sheets remaining between the roller part and the support part, and the print sheets remaining between the roller part and the support part are detected in the medium sensing step. If it is determined that there are a plurality of sheets, the medium separation step is performed again. As described above, the media sensing step and the media separation step may be repeatedly performed until the print sheet remaining between the roller part and the support part is detected as a single purchase.

Meanwhile, when the number of times of detecting the number of sheets is more than a set number of times, the returned printing sheets may be returned to one side of the to-be-printed object and the first position setting step may be performed again. This is because, if the number of sheets of print sheets separated in the media separation step is too large, the possibility of jams is increased during transfer of the to-be-printed object.

The setting number may be variously set according to the use condition of the printing apparatus. In other words, if the number of times of detecting the number of sheets is set to two, the media separation step may not be performed twice but only once, and all the printed sheets may be returned to one side of the to-be-printed object.

According to another aspect of the present invention, it is possible to provide an automatic teller machine comprising the above-described printing apparatus. That is, the automated teller machine may include a printing device for printing various transaction details and financial information on a printed matter, for example, a bankbook, a slip, or a receipt. Therefore, when the printing apparatus according to the embodiment of the present invention is employed in the automatic teller machine, it is not only possible to automatically turn over the pages of the account book simply and accurately when printing the account book, but also generate a plurality of pages abnormally. Customer complaints can also be resolved. However, the printing apparatus is not limited to the automatic teller machine, but may be employed in other apparatuses in which a to-be-printed object is formed by printing sheets.

In the printing apparatus and the control method of the printing apparatus according to the embodiment of the present invention, since the shielding unit shields the printing hole formed in the conveying passage during the transfer of the printed matter, it is possible to prevent the jam phenomenon that the printed matter is caught in the printing hole. have. Therefore, the reliability and marketability of the printing apparatus can be improved.

In addition, the printing apparatus and the control method of the printing apparatus according to the embodiment of the present invention can not only form the shielding unit in a very simple structure, but also reduce the manufacturing cost of the shielding unit. In addition, since the drum is formed in a structure that provides an elastic force in the pulling direction of the shielding panel, the shielding panel can more completely shield the printed hole by preventing the deflection and bending of the shielding panel.

In addition, in the printing apparatus and the method of controlling the printing apparatus according to the embodiment of the present invention, the second transfer unit transfers the to-be-printed object printed by the print unit, and the second transfer unit is dried with the printing ink on the contact area with the to-be-printed object. After the contact portion is formed to be in contact with the to-be-printed object, the contamination of the to-be-printed object due to the ink printed on the to-be-printed object can be prevented with a simple structure.

In addition, the printing apparatus and the control method of the printing apparatus according to the embodiment of the present invention, when the printed matter is inserted into the printing apparatus, the gap formed in the conveying passage is kept closed by the gate, thereby preventing the printed matter from being caught in the gap. can do. As a result, the transfer performance of the to-be-printed object by the transfer unit can be improved.

In addition, in the printing apparatus and the method of controlling the printing apparatus according to the embodiment of the present invention, when the magnetic strip of the printed object is disposed at a position corresponding to the gap, the read head is in the longitudinal direction of the gap in a state where the transfer of the printed matter is paused. To accurately read the information on the magnetic strip.

In addition, the printing apparatus and the control method of the printing apparatus according to the embodiment of the present invention, by setting the position where the print body and the print unit frame collide with the correct position of the print head, without using a separate position recognition sensor In general, the exact position of the print head can be easily determined.

In addition, the printing apparatus and the method of controlling the printing apparatus according to the embodiment of the present invention can accurately detect the position immediately before the collision between the print body and the print unit frame by using a barcode sensor that recognizes the barcode of the printed object, and this detection is performed. By reducing the moving speed of the print main body at the correct position, the impact generated when the print main body and the print unit frame collide with each other can be reduced.

In addition, the printing apparatus and the control method of the printing apparatus according to the embodiment of the present invention, the pulley and the belt can be easily attached to the transfer unit, it is possible to simplify the structure and size of the transfer unit.

In addition, the printing apparatus and the control method of the printing apparatus according to the embodiment of the present invention, by mounting a driving pulley for transferring the print and a driving belt for transmitting the driving force to the driven pulley, power for conveying the paper medium in the printing apparatus The delivery structure can be simplified.

In addition, in the printing apparatus and the control method of the printing apparatus according to the embodiment of the present invention, since the coupling position of the driving force transmission gear of the driving force transmission unit is set constant by the positioning member, the driving force transmission gear is generated by being coupled too close. The backlash reduction phenomenon of the driving force transmission gear can be prevented.

It may be formed as a first transfer belt 122b in close contact with one surface of the to-be-printed object (P). The first transfer part 122 may be disposed on at least one side of the upper or lower portion of the transfer passage 114. Hereinafter, the first transfer part 122 will be described as being disposed on both the upper and lower portions of the transfer passage 114, but the first transfer portion 122 is disposed only on either side of the upper or lower portion of the transfer passage 114 and the other. It is also possible to form a guide surface on one side.

On the other hand, in the present embodiment, the first transfer part 122 is a structure dedicated to the transfer of the to-be-printed object P between the doorway 112 and the print unit 130. That is, by changing the rotational direction of the first transfer pulley 122a of the first transfer unit 122, the transfer of the to-be-printed material P from the doorway 112 to the print unit 130 or the doorway from the print unit 130 The to-be-printed object P can be transferred to 112. However, unlike the present embodiment, the transfer unit for transferring the to-be-printed object P from the doorway 112 to the print unit 130, and the transfer unit for transferring the to-be-printed object P from the print unit 130 to the doorway 112. Each of the parts may be configured separately.

3 to 5, the second transfer part 124 transfers the to-be-printed object P at the time of printing of the print unit 130 to print the printed surface of the to-be-printed object P to be printed by the print unit 130. Is a device for updating. The second transfer unit 124 may be formed of the transfer pulleys 124a and the

transfer belts

122b and 124b in the same manner as the first transfer unit 122, and at least any one of an upper portion and a lower portion of the transfer passage 114. It can be placed on one side. Hereinafter, the second transfer part 124 will be described as being disposed on both the upper and lower portions of the transfer passage 114.

In addition, the first transfer part 122 and the second transfer part 124 may use a transfer belt in common. That is, the transfer units disposed above the transfer passage 114 among the first transfer unit 122 and the second transfer unit 124 may be independently disposed at positions spaced apart from each other with respect to the print unit 130, but the first transfer unit ( The transfer units disposed below the transfer passage 114 among the 122 and the second transfer unit 124 may be formed in a structure using the first transfer belt 122b in common.

On the other hand, in the second transfer part 124 disposed above the transfer passage 114, the printing ink I of the to-be-printed object P may be buried in the contact portion C with the to-be-printed object P. The printing ink I deposited on the contact portion C with the printed matter P may be completely dried, and then the contact portion C may be in contact with the printed matter P again. Therefore, it is possible to prevent the printing ink I of the to-be-printed object P from contaminating another part of the to-be-printed object P by the second transfer part 124 during the transfer of the to-be-printed object P. FIG.

For example, the second transfer part 124 disposed above the transfer passage 114 has a second transfer pulley 524a disposed at a position that can interfere with the to-be-printed object P printed by the print unit 130. , An idle pulley 124c disposed at a position that is not interfered with the to-be-printed object P, and a second transfer belt connected to the second transfer pulley 524a and the idle pulley 124c and transferring the to-be-printed object P ( 524b).

The second transfer pulley 524a may be formed in the same shape as the second transfer pulley 524a of the first transfer unit 122. The second transfer pulley 524a may be disposed to be in close contact with the upper surface of the to-be-printed object P. FIG.

The idle pulley 124c may be spaced apart from the upper side of the to-be-printed object P. FIG. The idle pulley 124c may be disposed to be spaced apart from the second transfer pulley 524a by a predetermined distance. In the separation distance between the second transfer pulley 524a and the idle pulley 124c, the ink on one side of the second transfer belt 524b dries sufficiently, and then one side of the second transfer belt 524b returns to the to-be-printed object P. FIG. It is formed with a sufficient distance to be contacted.

The second transfer belt 524b may be connected to the outer circumference of the second transfer pulley 524a and the idle pulley 124c. The second transfer belt 524b may be in close contact with the upper surface of the to-be-printed object P at the lower portion of the second transfer pulley 524a.

Therefore, when the second transfer belt 524b contacts the upper surface of the to-be-printed object P while the ink I printed on the upper surface of the to-be-printed object P is less dry during operation of the print unit 130, A part of printing ink I of (P) may be affixed to the contact part C of the 2nd conveyance belt 524b. However, since the contact portion C on which the printing ink is applied is rotated for a predetermined time along the second transfer pulley 524a and the idle pulley 124c and then returned to the position where it is in contact with the to-be-printed object P, 2 The printing ink on the contact portion C of the transfer belt 524b can be completely dried. That is, even when the contact portion C on which the printing ink is deposited is re-contacted with the to-be-printed object P, the printing ink on the second transfer belt 524b is buried on the upper surface of the to-be-printed object P, and the to-be-printed object P ) Can be prevented from being contaminated with ink.

1 to 3, the print unit 130 is movably provided in the printing hole 116 formed at the upper portion of the transfer passage 114 and of the printed matter P disposed in the printing hole 116. It is a device for printing on the upper surface.

For example, the print unit 130 is disposed above the print hole 116 to the print unit main body 132, the print unit main body 132, and the casing 110 that reciprocate along the print hole 116. A printing unit conveying mechanism 134 provided to convey the print unit main body 132, and a printing on the upper surface of the to-be-printed object P disposed on the lower side of the print unit main body 132 and disposed in the printing hole 116. It may include a print head 136 to perform.

The print unit body 132 may be provided with a mounting portion 132a for mounting a cartridge (not shown) filled with ink. The lower side of the print unit body 132 may be provided with an ink detection sensor (not shown) for detecting the ink concentration of the printed matter printed by the print head 136. Thus, the ink detection sensor can determine the ink shortage of the cartridge by detecting the ink concentration of the printed matter.

In addition, the ink detection sensor may recognize the information of the to-be-printed object P by detecting a barcode printed on the to-be-printed object P. FIG. That is, if the to-be-printed material (P) is a bankbook, the barcode information printed on the pages of the bankbook can be detected to recognize the page information of the bankbook. If the to-be-printed (P) is a receipt, the barcode printed on the receipt can be detected to display the information of the receipt. I can recognize it.

The print unit transfer mechanism 134 is provided in the print transfer pulleys 134a and the print transfer pulleys 134a provided in the casing 110 along the direction in which the print unit main body 132 is moved, and prints. The unit body 132 may include a print transfer belt 134b mounted at one side, and a print transfer guide 134c provided at the casing 110 to guide the transfer of the print unit body 132.

Here, the print feed pulleys 134a, the print feed belt 134b, and the print feed guide 134c may move the casing 110 in the direction in which the print unit body 132 is moved, that is, in the longitudinal direction of the print hole 116. Can be placed in. The print transfer guide 134c may be formed in a rod shape. The print unit body 132 may be formed with a guide hole 132b through which the print transfer guide 134c is movable.

1 to 3, the shielding unit 140 selectively shields the printing hole part 116 when the to-be-printed material P is transferred to prevent the phenomenon that the to-be-printed material P is caught by the printing hole part 116. It is a mechanism to do it. That is, when the to-be-printed material P is transferred to the printing hole 116, the shielding unit 140 may shield the printing hole 116 to prevent interference between the to-be-printed material P and the printing hole 116. have.

The shielding unit 140 may include a shielding unit 142 having one side connected to the print unit main body 132 of the print unit 130, and the other side of the shielding unit 142 when the print unit main body 132 moves. It may include a cashier 144 provided in the casing 110.

The shielding part 142 is disposed to be movable above the printing hole part 116 when the printing hole part 116 is shielded, and may be formed to have a larger area than the printing hole part 116. For example, the shield 142 may include a plate-shaped member having one end connected to the print unit body 132 in a cantilever shape. That is, the shield 142 may be moved together with the print unit body 132. As another example, the shield 142 may include a member having both ends connected to the print unit body 132 and the casing 110, and at least one portion of which is adjustable in length. The length adjusting portion of the shield 142 may be formed of an elastically stretchable structure, that is, a spring structure. Alternatively, the length adjusting portion of the shield 142 may be formed of an elastic material such as rubber. Therefore, the length of the middle portion of the shield 142 may be elastically increased or decreased as the print unit body 132 is moved. In addition, the length adjusting portion of the shielding portion 142 may be formed of foldable plate materials or pipe materials that can be inserted and pulled out. Thus, the length of the middle portion of the shield 142 may be adjusted as the plates or tubes overlap or spread as the print unit body 132 is moved.

One side of the shielding unit 142 may be moved together with the print unit body 132, and the other side of the shielding unit 142 may be arranged to be withdrawn or received in the cashier unit 144. Therefore, since the cashier 144 prevents the size of the shield unit 140 from increasing due to the length of the shield 142, the printing apparatus 100 may be compactly formed.

Hereinafter, in the present embodiment, it will be described that the shield unit 140 is formed of a shield panel and a drum. That is, the shielding part 142 is described as a shielding panel having one end connected to the print unit body 132, and the cashier 144 is provided in the casing 110 so that the other end of the shielding panel 142 is wound on the outer circumferential surface thereof. Explain.

The shielding panel 142 is a plate-shaped member formed to have a long area to shield the printing hole 116, and may be wound in a winding shape on the outer circumference of the drum 144. Therefore, when the print unit body 132 is moved, the shielding panel 142 may be opened or closed while the shielding panel 142 is wound or unwound by the drum 144.

The drum 144 may be rotatably provided in the casing 110 and positioned above the printing hole 116. Therefore, one end of the shielding panel 142 may be disposed to be movable above the printing hole 116, and the other end of the shielding panel 142 may be wound around the drum 144 upwardly from the printing hole 116. Can be.

In addition, the drum 144 may be formed in a structure that provides an elastic force in the direction to pull the shielding panel 142. That is, the drum 144 may be connected to the other end of the shielding panel 142, and may be provided in the casing 110 so as to be elastically supported in the rotational direction in which the shielding panel 142 is wound. Therefore, the shielding panel 142 disposed between the print unit main body 132 and the drum 144 can maintain a horizontal state without falling down by the elastic force of the drum 144 even without a separate supporting member.

When the shielding panel 142 and the drum 144 are arranged as described above, the printing hole 116 may not be completely shielded due to the sagging or bending of the shielding panel 142. In particular, a portion of the shielding panel 142 may be prevented from being inserted into the printing hole part 116 while sagging or bending.

Looking at the operation of the printing apparatus 100 according to the present invention configured as described above are as follows.

First, the to-be-printed object P is put into the entrance and exit 112 of the printing apparatus 100, and the to-be-printed object P is arrange | positioned at the conveyance passage 114 of the casing 110. FIG. Thereafter, the first transfer part 122 of the transfer unit 120 transfers the to-be-printed object P to the print unit 130, whereby the to-be-printed object P is disposed below the printing hole 116 of the transfer passage 114. Locate the part to print.

At this time, since the printing hole 116 is shielded by the shielding panel 142 of the shielding unit 140, the printing hole part 116 and the printing object (P) are in the process of passing through the printing hole part 116. The jamming phenomenon of P) can be prevented.

Referring to FIG. 1, the drum 144 of the shielding unit 140 is disposed at the right end of the printing hole 116, and the print unit body 132 is disposed at the left end of the printing hole 116. That is, since one end of the shielding panel 142 together with the print unit main body 132 is disposed at the left end of the printing hole 116, the shielding panel 142 is released from the drum 144 to cover the printing hole 116. Shield.

When the printing surface of the to-be-printed object P is disposed to correspond to the printing hole 116 as described above, the to-be-printed object P enters the second transfer part 124 and is transportable by the second transfer part 124. do.

Referring to FIG. 2, when the print unit transport mechanism 134 of the print unit 130 moves the print unit main body 132 to the right, the print head 136 performs printing on the printing surface of the to-be-printed object P. FIG. do.

As described above, when the print unit conveyance mechanism 134 reciprocates the print unit main body 132 to the left and right directions, and the print head 136 performs printing on the print surface of the object P, the second conveying unit 124 The to-be-printed object P is transferred and the printing surface of the to-be-printed object P is updated.

4 and 5, as the second transfer part 124 transfers the to-be-printed object P, the second transfer belt 524b of the second transfer part 124 prints the to-be-printed object P. As shown in FIG. The ink I printed on the surface may be contacted, and a part of the printing ink I of the to-be-printed object P may be buried in the contact portion C of the second transfer belt 524b.

However, since the contact portion C, which has been stained with ink, has a structure of returning from the second transfer pulley 524a to the second transfer pulley 524a via the idle pulley 124c, the contact of the second transfer pulley 524a. The ink deposited on the site C may be completely dried before contacting the substrate P again. Therefore, in the process of transferring the to-be-printed object P by the second transfer unit 124, the ink I printed on one surface of the to-be-printed object P is transferred to the to-be-printed object P through the second transfer belt 524b. Contamination of the other side can be prevented.

When the print job by the print unit 130 is completed, the second conveying unit 124 and the first conveying unit 122 operate in opposite directions to move the to-be-printed object P from the print unit 130 to the doorway 112. Transfer.

At this time, as in the case where the to-be-printed object P is transferred to the print unit 130, the print unit body 132 is disposed at the left end of the print hole 116 so that the print hole 116 is disposed on the shielding panel 142. Are shielded by Therefore, it is possible to prevent a phenomenon in which the to-be-printed object P is caught by the printing hole 116 while the transfer unit 120 transfers the to-be-printed object P from the print unit 130 to the doorway 112.

Figure 6 is a perspective view of a financial automated device including a printing device according to an embodiment of the present invention. Here, since the printing apparatus 100 illustrated in FIG. 6 has a similar configuration to that of the printing apparatus 100 illustrated in FIGS. 1 to 5, a description thereof will be omitted.

Referring to FIG. 6, the automated teller machine 200 according to the embodiment of the present invention includes a deposit and withdrawal unit 210 in which a paper medium is deposited and withdrawn, a display unit 220 displaying a transaction history and various information of a paper medium in real time, An operation unit 230 for receiving information for various financial transactions, and a bankbook processing unit 240 for recognizing a variety of information of the bankbook and printing the transaction details on the bankbook.

The bankbook processing unit 240 includes a printing device 100 for printing various transaction details on the bankbook. However, since the printing apparatus 100 may prevent the jam phenomenon and the contamination caused by the ink generated during the transfer of the passbook, as described above, the automatic teller machine 200 may be jammed due to the jam phenomenon of the printing apparatus 100. The unusable state can be minimized, and consumer complaints due to ink contamination of the printing apparatus 100 can be prevented.

On the other hand, the

printing apparatus

300, 400, 500, 600 of various embodiments to be described later may also be employed in the automated teller machine 200, a detailed description thereof will be omitted.

7 is a perspective view showing a printing apparatus according to another embodiment of the present invention. 8 and 9 are operation state diagrams showing an example of the printing apparatus shown in FIG. 7, and FIG. 10 is a view showing a gate of the printing apparatus shown in FIG. 7. 11 is an operational state diagram showing another example of the printing apparatus shown in FIG.

7 to 11, the same reference numerals as those shown in FIGS. 1 to 6 denote the same members. Hereinafter, descriptions will be made mainly on points different from the printing apparatus 100 illustrated in FIGS. 1 to 6.

7 to 9, the difference between the printing apparatus 300 according to another embodiment of the present invention and the printing apparatus 100 illustrated in FIGS. 1 to 6 is a magnetic strip formed on the to-be-printed material P. FIG. a read head 340 movably provided in a gap 332 formed in the transfer unit 320 to read a magnetic strip P1, and one side of the read head 340 connected to the to-be-printed object P In order to prevent the phenomenon that is caught in the gap 332 is different from the gate 350 that selectively shields the gap 332 during transfer of the object (P).

The transfer unit 320 may include a doorway 112 through which the to-be-printed object P enters and exits, and may form a transfer passage of the to-be-printed object P. FIG. In the transfer unit 320, a gap 332 may be formed in a shape corresponding to the magnetic strip P1. The read head 340 may move along the gap 332 to read information of the magnetic strip P1 disposed in the gap 332.

In general, the gap 332 is formed in the lower portion of the transfer passage of the transfer unit 320, the read head 340 may be disposed below the magnetic strip (P1). The read head 340 may be formed as a sensor capable of reading the information on the object P while moving along the magnetic strip P1. In the following embodiment of the present invention, the read head 340 is described with an example provided on the bottom of the magnetic strip P1, but the present invention is not limited or limited by the position where the read head is provided.

The gate 350 is a member that opens and closes the gap 332, and one side of the gate 350 is connected to the read head 340 to be moved together with the read head 340. The gate 350 may prevent the jam phenomenon that the to-be-printed object P is caught by the gap 332 by keeping the gap 332 closed when the to-be-printed object P enters or exits the entrance 112.

That is, the gap 332 may be formed in the transfer unit 320, and may be opened and closed by the gate 350 according to the movement of the read head 340. Accordingly, the gap 332 is opened and closed by the gate 350, but since the gate 350 is opened and closed by the read head 340, the opening and closing state of the gap 332 is switched by the movement of the read head 340. Can be.

On the other hand, the transfer direction of the to-be-printed object P according to another embodiment of the present invention is described as being the same direction as the direction in which the to-be-printed material P is inserted, but the transfer direction of the to-be-printed material P according to the conditions required by the present invention. The silver may be formed in a direction different from that in which the to-be-printed object P is inserted.

In addition, the magnetic strip P1 formed at the lower portion of the to-be-printed material P inserted into the printing apparatus 300 may be formed in a vertical direction or a horizontal direction with respect to the transfer direction of the to-be-printed material P. FIG. The magnetic strip P1 includes basic information of the to-be-printed object P. FIG. For example, when the to-be-printed material P is an account book, financial information of the customer may be stored in the magnetic strip P1. Hereinafter, in the present embodiment, it will be described that the magnetic strip P1 is formed in a direction perpendicular to the transfer direction of the to-be-printed object P. FIG.

When the to-be-printed object P, in which the magnetic strip P1 is formed in a direction perpendicular to the transport direction of the to-be-printed material P, is inserted into the doorway 112, the read head 340 keeps the gap 332 closed. It can move with the gate 350 to make it. In an embodiment of the present invention, the read head 340 may move to an initial position at which the magnetic strip P1 can be read, that is, the gap 332 is closed. However, the initial position of the read head 340 is not limited to the position where the gap 332 is closed, and the initial position of the read head 340 may be changed according to design conditions and circumstances required by the invention.

As described above, the to-be-printed object P may be transferred to the position where the magnetic strip P1 and the gate 350 correspond to each other while maintaining the gap 332. At this time, since the front end of the to-be-printed object P has already passed through the gap 332 in the closed state by the gate 350, the jam phenomenon that the to-be-printed object P is caught by the gap 332 is prevented.

Meanwhile, when the magnetic strip P1 is disposed at a position corresponding to the gate 350, the transfer unit 320 temporarily stops the transfer of the object P. FIG. When the transfer unit 320 temporarily stops the transfer of the to-be-printed object P, the read head 340 moves along the magnetic strip P1 along the longitudinal direction of the gap 332 to transfer information of the to-be-printed object P. FIG. Can be read. That is, since the read head 340 reciprocates the surface of the magnetic strip P1 along the gap 332, the read head 340 can read the magnetic strip P1 at least twice so that the magnetic strip P1 is read. Can accurately read the information.

On the other hand, the transfer unit 320 may be provided with a sensor for determining whether the to-be-printed object (P). For example, the transfer unit 320 is disposed horizontally with the direction in which the to-be-printed material P is transferred, and determines the exact position of the to-be-printed object P whether to skew or shift. , 137b and 137c. Here, the skew means that the paper medium is conveyed in an oblique state, and the shift means that the paper medium is conveyed in a state in which it is biased to either side from the center of the conveying path. The to-be exact position detecting sensors 137a, 137b, and 137c may be provided at positions close to the doorway 112. In this way, when the to-be-positioned position detecting sensors 137a, 137b, and 137c are provided in close proximity to the doorway 112, it is easy to immediately respond to skew or shift of the to-be-printed object P. FIG.

In addition, the transfer unit 320 may detect the magnetic strip alignment sensor 138a or 138b that detects whether the magnetic strip P1 is disposed above the gate 350 or the read head 340 as the object P is transferred. , 138c). The magnetic strip position sensor 138a, 138b, and 138c may be disposed in the transfer unit 320 in parallel with the transfer direction of the object P. FIG. Accordingly, the magnetic stiffer position sensor 138a, 138b, or 138c may detect whether the magnetic strip P1 overlaps the gate 350 or the read head 340. When the magnetic strip exact position sensor 138a, 138b, and 138c is provided in this way, the position where the read head 340 overlaps the magnetic strip P1 is accurately sensed, so that the read head 340 is used to remove the magnetic strip P1. Can read at the correct time. When the reading head 340 finishes reading the information of the to-be-printed object P, the transfer unit 320 can transfer the to-be-printed object P again.

9 and 10, the gate 350 may include a spring part 352 and a housing 354. One side of the spring part 352 may be connected to the read head 340 to open and close the gap 332 according to the movement of the read head 340, and the other end of the spring part 352 may be withdrawn into the housing 354. It can possibly be wound. At this time, the winding part 352 is a structure that does not provide a separate tension itself is not loosened or wound.

The winding part 352 may be wound inside the housing 354 located below the lower surface F of the transfer passage. If the winding part 352 is wound upward based on the lower surface F of the transfer passage, the edge of the to-be-printed material P transported along the upper surface of the gate 350 is caught by the winding part 352 and jams are caught. May occur. In order to prevent this, the spring portion 352 may be formed in a structure that is wound downward from the lower surface (F) of the transfer passage. Therefore, the possibility that the to-be-printed object P interferes with the spring part 352 can be eliminated, and the phenomenon that the wound part of the spring part 352 is naturally loosened by load can be prevented.

As described above, when the gate 350 provided in the gap 332 is opened or closed depending on whether or not the to-be-printed object P is transported, the to-be-printed object P transported by the transfer unit 320 is caught in the gap 332 and jammed. It can prevent the phenomenon that occurs. In addition, when the transfer of the printed matter P is temporarily stopped at the position where the magnetic strip P1 and the read head 340 correspond, the read head 340 moves along the length direction of the gap 332 to cause the magnetic strip to move. Information of (P1) can be read.

On the other hand, in the control method of the printing apparatus 300 according to another embodiment of the present invention, the to-be-printed object P is transferred to the transfer path of the transfer unit 320 using the to-be-positioned position detecting sensors 137a, 137b, and 137c. Detecting whether or not to enter, detecting the entry state of the to-be-printed object P using the exact position sensor (137a, 137b, 137c), and if it is detected that the to-be-printed object P is normally entered, the gate ( When the gap 332 is kept closed by the 350, the magnetic strip P1 is moved to the gate 350 during the transfer of the object P using the magnetic stiffer position sensors 138a, 138b, and 138c. Or detecting whether the magnetic strip P1 is located above the gate 350 or the read head 340, and temporarily transferring the to-be-printed object P. Stopping, and the read head 340 moves along the gap 332 Reading the magnetic strip P1.

At this time, in the step of reading the magnetic strip, as the gap 332 is opened and closed by the gate 350 in a state in which the transfer of the to-be-printed object P is paused by the transfer unit 320, the read head 340 is opened. The magnetic strip P1 can be read. That is, when the gate 350 opens the gap 332 while the transfer unit 320 pauses the transfer of the object P, the read head 340 may read the magnetic strip P1 first. have. When the gate 350 shields the gap 332, the read head 340 may read the magnetic strip P1 in the opposite direction in the opposite direction. As the gate 350 is reciprocated as the gap 332 is opened and closed as described above, the read head 340 may read the magnetic strip P1 at least twice to more accurately read the magnetic strip P1.

The control method of the printing apparatus 300 will be described in more detail. When the to-be-printed object P is inserted through the entrance and exit 112, the to-be-printed position detecting sensors 137a, 137b, and 137c may determine whether the to-be-printed object P is inserted into the correct position. The to-be-positioned detection sensor 137a, 137b, or 137c is a sensor capable of detecting a skew or shift of the to-be-printed object P when the to-be-printed object P is inserted. ) May be disposed at a position close to the doorway 112 to determine the insertion state.

Here, when the to-be exact position sensor 137a, 137b, or 137c detects the to-be-printed object P, the gap 332 may be kept closed by the gate 350. The state where the gap 332 remains closed is the initial position of the read head 340, and it is preferable that the to-be-printed object P is inserted at the initial position of the read head 340.

Then, when the to-be-printed object P is transported along the transport passage of the transport unit 320, the magnetic strip P1 using the magnetic strip position sensor 138a, 138b, and 138c provided in the transport unit 320. It may be detected whether it is located above the gate 350 or the read head 340. The magnetic strip position sensor 138a, 138b, 138c is arranged in parallel with the direction in which the object P is transferred so that the magnetic strip P1 and the gate 350 or the read head as the object P is transferred. The position at which the 340 overlaps may be detected.

In addition, when the magnetic strip exact position sensor 138a, 138b, 138c detects a position where the magnetic strip P1 overlaps the gate 350 or the read head 340, the transfer unit 320 may have a print P. ) Can be temporarily stopped. When the transfer unit 320 temporarily stops the transfer of the to-be-printed object P, the read head 340 may move along the gap 332 and read the magnetic strip P1. At this time, the read head 340 reads the magnetic strip P1 at least twice while moving with the gate 350 that opens and closes the gap 332.

When the reading of the magnetic strip P1 by the read head 340 is finished, the transfer unit 320 may transfer the to-be-printed object P to the print unit 130, and the print unit 130 may print the to-be-printed object ( You can print on P). In this case, the gap 332 may be kept closed by the gate 350 until the to-be-printed object P is discharged through the entrance 112.

11 shows another example of the printing apparatus 300 according to the present embodiment. That is, the magnetic strip P1 may be formed long in the conveying direction of the to-be-printed object P in the to-be-printed object P. FIG. As such, when the magnetic strip P1 is formed long in the horizontal direction with respect to the conveying direction of the to-be-printed object P, the read head 340 has a gap in order to be disposed at a position where the magnetic strip P1 of the to-be-printed object P passes. May be moved along 332.

Therefore, the to-be-printed object P can be continuously conveyed with the gap 332 and the magnetic strip P1 arranged to correspond to each other, and the read head 340 is moved together when the to-be-printed object P is conveyed. The information of the magnetic strip P1 can be read. Of course, the gate 350 may move along the gap 332 together with the read head 340 to prevent the to-be-printed material P from being caught in the gap 332 and delayed transfer or jam.

12 and 13 are partial perspective views illustrating main parts of a printing apparatus according to still another embodiment of the present invention. 12 to 13, the same reference numerals as the reference numerals shown in FIGS. 1 to 6 denote the same members. Hereinafter, descriptions will be made mainly on points different from the printing apparatus 100 illustrated in FIGS. 1 to 6.

12 and 13, the printing apparatus 400 according to another exemplary embodiment of the present invention differs from the printing apparatus 100 illustrated in FIGS. 1 to 6 in the correct position of the print head 136. The mechanism for setting the mechanically is different.

The print unit 430 of the present embodiment is formed under the print unit frame 432, the print main body 132 provided to be movable in the print unit frame 432, and the print main body 132 to be printed (P). A print head 136 for printing various types of information including a transaction history, a print unit transport mechanism 134 for driving the print body 132, and a print head provided in the print body 132 and the print unit frame 432. It may include a sensor 436 provided in the 136 to recognize the barcode (B) of the to-be-printed object (P). Here, since the print main body 132, the print unit transport mechanism 134, and the print head 136 are the same as those shown in Figs. 1 to 6, detailed description thereof will be omitted.

The print unit frame 432 supports and fixes the print head 136 and the print unit transport mechanism 134 so that the printed matter P can be stably printed. The print unit frame 432 may include a bottom portion F supporting the to-be-printed object P, and sidewalls 432a formed on one side of the bottom portion F to collide with the print body 132. .

Here, the bottom portion F of the print unit frame 432 may be formed in communication with the transfer passage of the transfer unit 120 to support the to-be-printed object P. The sensing hole 438 may be formed in the bottom portion F. The sensing hole 438 may be formed at a position spaced apart from the sidewall 432a by a predetermined distance. That is, the sensing hole 438 may be formed at a position close to the side wall 432a, and the print body 132 before the collision between the print body 132 and the print unit frame 432 using the sensing hole 438. The movement speed of can be appropriately reduced.

The print head 136 is also provided with a sensor 436 capable of recognizing the barcode B of the printed side page of the to-be-printed object P. FIG. The sensor 436 is a kind of barcode sensor capable of recognizing the printed surface of the to-be-printed object P by recognizing the barcode B of the to-be-printed object P. FIG. Hereinafter, in the present embodiment, the sensor 436 is limited to a bar code sensor, but various sensors other than the bar code sensor may be used. That is, when the barcode sensor 436 recognizes the barcode on the printing surface of the to-be-printed object P, the moving speed of the print main body 132 may be slowed down.

In detail, the speed of the print body 132 may be controlled by using the barcode sensor 436 and the detection hole 438. That is, the driving speed of the print body 132 may be reduced based on the time when the barcode sensor 436 detects the detection hole 438, and the detection hole 438 is detected by the barcode sensor 436. The viewpoint may be referred to as the deceleration timing of the print body 132.

The reason for decelerating the driving speed of the print main body 132 as described above is that the print main body 132 and the print unit frame 432 are damaged by the impact of the collision in the process of setting the correct position of the print head 136. This is because it is possible to prevent the noise from occurring due to the collision between the print body 132 and the print unit frame 432.

That is, when the to-be-printed object P is inserted into the printing apparatus 400, the print unit conveyance mechanism 134 determines the print head 136 in order for the print head 136 to print various information on the to-be-printed object P. FIG. Move to position If the printing proceeds in a state where the correct position of the print head 136 is not determined, printing defects such as printing the pattern printed on the to-be-printed object P may not be constant or may be overprinted. Therefore, it is very important to determine the correct position of the print head 136, that is, the initial position of the start of printing, before starting printing.

In this embodiment, the correct position of the print head 136 is set to a position or moment at which the print head 136 contacts or collides with the side wall 432a of the print unit frame 432. As described above, by determining the position where the print head 136 collides with the side wall 432a of the print unit frame 432 as the correct position of the print head 136, the correct setting of the print head 136 may be facilitated. In addition, it is possible to simply determine the exact position of the print head 136 mechanically without using a separate position detection means or a sensor.

The print unit transport mechanism 134 is formed in parallel with a print transport belt 134b connected to the print body 132, a DC motor (not shown) for driving the print transport belt 134b, and a print transport belt 134b. And a print transfer guide 134c for guiding the linear movement of the print body 132, and a linear encoder 434 for obtaining speed information of the print body 132.

Hereinafter, a method of setting the correct position of the print head 136 in the printing apparatus 400 according to another embodiment of the present invention will be described in detail.

First, a step in which the to-be-printed material P enters the print unit frame 432, a step in which the print main body 132 is driven, a step in which the driving speed of the print main body 132 is decelerated, and the print head 136 are in the correct position. And printing may be performed by the print head 136. In particular, in the step of arranging the print head 136, the position where the print body 132 collides with the side wall 432a of the print unit frame 432 may be recognized as the position of the print head 136.

In addition, in the step in which the driving speed of the print body 136 is decelerated, the driving speed of the print head 136 may be reduced as the print head 136 approaches the side wall 432a of the print unit frame 130. As the print head 136 approaches the side wall 432a as described above, the driving speed of the print head 136 may be reduced to prevent the print head 136 from colliding with the side wall 432a at high speed.

Meanwhile, the print head 136 may move left and right, and as the print head 136 moves, the barcode sensor 436 provided to the print head 136 may detect the detection hole 438. As such, when the driving speed of the print body 136 is decelerated, when the barcode sensor 436 detects the sensing hole 438, the driving speed of the print head 136 is reduced to reduce the driving speed of the print head 136 and the side wall ( 432a) can be prevented from sudden collision. To this end, the sensing hole 438 may be formed at a position close to the sidewall 432a.

In addition, when the driving speed of the print main body 136 is decelerated, when the barcode sensor 135 recognizes the barcode B of the printed matter P, the driving speed of the print head 136 may be reduced. have. That is, when the barcode sensor 436 recognizes the barcode B of the to-be-printed object P as described above, the print unit transport mechanism 134 reduces the driving speed of the print head 136, thereby causing the print head 136 to be printed. Can be prevented from colliding with the side wall 432a of the print unit frame 432.

On the other hand, the detection hole 438 may be used to check whether the barcode sensor 436 is operating normally. That is, it is possible to check the operation state of the barcode sensor 436 by checking whether the barcode sensor 436 is received by the detection hole 438.

On the other hand, the print unit transport mechanism 134 may adjust the driving speed of the print main body 132 in the order of slow speed, continuous speed and slow speed. As described above, when the driving speed of the print main body 132 starts slowly, when the print main body 132 starts between the sensing hole 438 and the side wall 432a of the print unit frame 432, the print main body 132. ) Can be prevented from colliding with the side wall 432a of the print unit frame 432 at a high speed.

For example, when the print main body 132 is disposed on the right side of the sensing hole 438, the print unit transport mechanism 134 is driven to move the print main body 132, and the sensing hole 438 is applied to the barcode sensor 135. ), It may be determined that the print main body 136 is approaching the side wall 432a of the print unit frame 432, thereby reducing the driving speed of the print main body 132. However, when the initial position of the print body 132 is between the side wall 432a and the sensing hole 438, the barcode sensor 436 cannot detect the sensing hole 438 even when the print body 132 moves. It is a state. Therefore, if the print body 132 starts quickly, the print body 132 may collide with the side wall 432a so that the print body 132 may be damaged. In this case, if the start speed of the print main body 132 starts slowly, the print head 136 may start even if the print head 136 starts between the side wall 432a and the sensing hole 438. Can be prevented from colliding strongly with the side wall 432a.

When the print head 136 is disposed at the correct position as described above, the print head 136 may print information on the to-be-printed object P. FIG.

FIG. 14 is a sectional view showing a printing apparatus according to another embodiment of the present invention, and FIG. 15 is a side view showing a main part of the printing apparatus shown in FIG. 16 and 17 are side and perspective views illustrating the transfer unit and the driving force transmitting unit shown in FIG. 15, and FIG. 18 is a view illustrating the main parts of the driving force transmitting unit shown in FIG. 17.

14 to 18, the same reference numerals as those shown in Figs. 1 to 6 denote the same members. Hereinafter, descriptions will be made mainly on points different from the printing apparatus 100 illustrated in FIGS. 1 to 6.

14 to 18, the printing apparatus 500 according to another embodiment of the present invention differs from the printing apparatus 100 illustrated in FIGS. 1 to 6 by applying a driving force to the transfer unit 520. The configuration to deliver is different.

The transfer unit 520 is provided on the transfer passage 114 of the casing 110 to transfer the to-be-printed object P along the transfer passage 114. The conveying unit 520 is provided along the lower portion of the conveying passage 114 and provided along the upper portion of the conveying passage 114, the first conveying unit 522, which conveys the to-be-printed material P, and the first conveying unit ( A second transfer unit 524 elastically in close contact with the 522, and a driving unit 528 connected to the first transfer unit 522 to provide a driving force to the first transfer unit 522.

That is, the first transfer unit 522 may be provided in the lower transfer guide 523 forming a lower portion of the transfer passage 114, and the second transfer unit 524 may form an upper portion of the transfer passage 114. The upper transfer guide 525 may be provided. The driving unit 528 may be formed of a motor. The driving gear 528a may be provided on the rotation shaft of the driving unit 528. The driving gear 528a may be connected to the driving gear 529 provided in the first rotation shaft 522c of the first transfer unit 522. Therefore, the driving force of the driving unit 528 may be transmitted to the first transfer unit 522 through the driving gear 528a and the driving gear 529.

The first conveying unit 522 may include a plurality of first conveying pulleys 522a and a plurality of first conveying pulleys 522a which are arranged in a lower conveyance guide 523 in the conveying direction of the object P. FIG. And a first rotating shaft 522c disposed on the first transfer belt 522b and the lower transfer guide 523 and connecting the first transfer pulleys 522a arranged in a direction orthogonal to the transfer direction of the to-be-printed material P. Can be.

The second conveying unit 524 may include a plurality of second conveying pulleys 524a and second conveying pulleys 524a disposed in the upper conveying guide 525 in the conveying direction of the to-be-printed material P. And a second rotating shaft 524c disposed on the second conveyance belt 524b and the upper conveying guide 525 and connecting the second conveying pulleys 524a disposed in a direction orthogonal to the conveying direction of the substrate P. FIG. Can be. Here, a plurality of second transfer units 524 may be disposed along the transfer direction of the object P. FIG. The printing hole 116 in which the print unit is disposed and the page turning hole 118 in which the page turning unit is disposed may be formed in the spaced portion of the second transfer unit 524.

In addition, the second rotation shaft 524c may be disposed on the upper transfer guide 525 to be rotatable and to be movable up and down. The second transfer unit 524 further includes a leaf spring 526 that provides an elastic force to the second rotation shaft 524c.

16 to 18, the printing apparatus 500 may further include a driving force transmission unit 560. The driving force transmission unit 560 is a device which is disposed in the first transfer unit 522 and the second transfer unit 524 to transfer the driving force of the first transfer unit 522 to the second transfer unit 524. In addition, the driving force transmission unit 560 is a device that is disposed in the drive unit 528 and the first transfer unit 522 to transfer the driving force of the drive unit 528 to the first transfer unit 522.

For example, the driving force transmission unit 560 may include driving force transmission gears 561 and 562 connected to the first transfer unit 522 and the second transfer unit 524, and driving force transmission gears 561 and 562, respectively. And positioning

members

563 and 564 which are formed at and set engagement positions of the driving force transmission gears 561 and 562. The driving force transmission unit 560 may be provided to correspond to each other in the three second transfer unit 524 and each portion of the first transfer unit 522 facing the three second transfer unit 524.

The driving force transmission gears 561 and 562 are provided in the first driving force transmission gear 561 and the second transmission unit 524 connected to the first transfer unit 522 and are coupled to the first driving force transmission gear 561. The second driving force transmission gear 562 may be included. The first driving force transmission gear 561 may be provided at an end portion of the first rotation shaft 522c of the first transfer unit 522, and the second driving force transmission gear 562 may face the first driving force transmission gear 561. It may be provided at the end of the second rotation shaft 524c of the second transfer unit 524 to be.

The

positioning members

563 and 564 are provided on both side surfaces of the first positioning member 563 and the second driving force transmission gear 562, respectively provided on both sides of the first driving force transmission gear 561. The first driving force transmission gear 561 and the second driving force transmission gear 562 may include a second positioning member 564 in contact with the first positioning member 563 when the coupling.

The

positioning members

563 and 564 may be formed in a circular shape or a ring shape. For example, the

positioning members

563 and 564 may be plate members formed in circular or ring shapes on both sides of the driving force transmission gears 561 and 562.

Accordingly, the first driving force transmission gear 561 and the first positioning member 563 may be provided in the first transfer unit 522, and the second driving force transmission gear 562 may be provided in the second transfer unit 524. The second positioning member 564 may be provided. When the first driving force transmission gear 561 and the second driving force transmission gear 562 are coupled, the driving force of the first transfer unit 522 is transmitted through the first driving force transmission gear 561 and the second driving force transmission gear 562. May be transferred to the second transfer unit 524. In addition, since the first positioning member 563 and the second positioning member 564 are rotated while being in contact with each other, the first driving force transmission gear 561 and the second driving force transmission gear 562 are the first positioning member. The radius of the 563 and the second positioning member 564 may be uniformly disposed at a distance equal to the length of the sum.

Interference avoidance grooves G may be formed between the driving force transmission gears 561 and 562 and the

positioning members

563 and 564 as described above. The interference avoiding groove G may be formed deeper than the root of the gear teeth of the driving force transmission gears 561 and 562. This is because the gear tooth ends of the driving force transmission gears 561 and 562 are of sufficient depth not to interfere with the bottom surface of the interference avoiding groove G regardless of the

positioning members

563 and 564.

That is, when the first driving force transmission gear 561 and the second driving force transmission gear 562 are rotated in a coupled state, flow flows in the left and right directions to the first driving force transmission gear 561 and the second driving force transmission gear 562. Can be generated. However, since the interference avoiding groove portion G is formed between the driving force transmission gears 561 and 562 and the

positioning members

563 and 564, the gear value of the first driving force transmission gear 561 is the second positioning member. A phenomenon that interferes with 564 and a phenomenon where the gear value of the second driving force transmission gear 562 interferes with the first positioning member 563 can be avoided. Accordingly, the driving force transmission unit 560 is caused by the interference between the first driving force transmission gear 561 and the second positioning member 564 or the interference of the second driving force transmission gear 562 and the first positioning member 563. The phenomenon that the driving force transmission performance of the deterioration can be prevented.

Meanwhile, the driving force transmission unit 560 is connected to the driving force transmission shaft 566 connected to the driving force transmission gears 561 and 562, and the rotational force of the driving force transmission shaft 566 and the transfer unit 520, and transmits the rotation shaft and the driving force. A position compensating member 568 may be further provided to compensate for a change in position of the shaft 566. That is, the position compensation member 568 compensates the vertical position of the second transfer unit 524 according to the thickness of the to-be-printed material P passing between the first transfer unit 522 and the second transfer unit 524. It is a member.

The position compensating member 568 may not be deformable in the rotational direction and the axial direction of the driving force transmission shaft 566 and the first rotation shaft 522c. On the other hand, the position compensation member 568 may be formed in a structure that is bent in a direction orthogonal to the axial direction of the driving force transmission shaft 566 and the first rotation shaft 522c. If the position compensating member 568 is rotatably connected in the rotational direction of the driving force transmission shaft 566 and the first rotation shaft 522c, it is impossible to transmit the rotational force to the driving force transmission shaft 566 and the first rotation shaft 522c. Because. In addition, when the position compensation member 568 is movably connected in the axial direction of the driving force transmission shaft 566 and the first rotation shaft 522c, the positions of the driving force transmission shaft 566 and the first rotation shaft 522c may be changed. This is because the position of the pulley and gear may be out of position.

The position compensating member 568 as described above may be formed as a universal joint or a link having both ends connected to the driving force transmission shaft 566 and the first rotation shaft 522c. Hereinafter, the position compensation member 568 will be described as being a universal joint. As described above, when the second driving force transmission gear 562 is connected to the end of the second rotation shaft 524c through the driving force transmission shaft 566 and the position compensation member 568, the vertical movement of the second transfer unit 524 moves up and down. It is possible to compensate for the change in position according to. That is, since the position compensation member 568 compensates for the positional change of the second rotation shaft 524c, the position of the driving force transmission shaft 566 is kept constant so that the first driving force transmission gear 561 and the second driving force transmission gear ( The engagement position of 562 may also be kept constant.

When the driving unit 528 is driven, the driving force of the driving unit 528 is transmitted to the first rotation shaft 522c having the driving gear 529 through the driving gear 528a. That is, the drive gear 528a and the drive gear 529 are rotated by the driving force of the drive 528, and the first rotation shaft 522c with the drive gear 529 is also rotated. When the first rotary shaft 522c with the driving gear 529 is rotated by the driving force of the driving unit 528, the first transfer pulley 522a is rotated together with the first rotary shaft 522c, and the first transfer pulley ( The first transfer belt 522b is rotated together with 522a. When the first transfer belt 522b is rotated as described above, the first rotation shafts 522c not connected to the drive gear 529 are also rotated by the first transfer belt 522b and the first transfer pulley 522a. . Therefore, when the drive direction of the drive part 528 is changed, the rotation direction of the 1st conveyance belt 522b also switches, and the conveyance direction of the to-be-printed object P will also rotate.

Meanwhile, when the first rotation shaft 522c of the first transfer unit 522 is rotated, the first driving force transmission gears 561 connected to the ends of the first rotation shafts 522c are also rotated. When the first driving force transmission gears 561 rotate, the second driving force transmission gear 562 engaged with the first driving force transmission gear 561 rotates.

As described above, when the second driving force transmission gear 562 is rotated, the driving force transmission shaft 566 connected to the second driving force transmission gear 562 is rotated, and the position compensation member 568 together with the driving force transmission shaft 566 is rotated. The second rotating shaft 524c is rotated by the position compensating member 568.

Therefore, as the second rotation shaft 524c is rotated, the second transfer pulley 524a and the second transfer belt 524b may rotate. The second transfer pulley 524a and the second transfer belt 524b transfer the to-be-printed object P together with the first transfer pulley 522a and the second transfer belt 524b.

On the other hand, when the to-be-printed object P is conveyed by the 1st conveying unit 522 and the 2nd conveying unit 524, according to the thickness of the to-be-printed object P, the 2nd conveying belt of the 2nd conveying unit 524 ( 524b, the second feed pulley 524a, and the second rotation shaft 524c are elastically moved in the vertical direction. That is, since the second rotation shaft 524c is disposed to be elastically movable in the vertical direction, the position may be elastically changed according to the thickness of the to-be-printed object P. FIG. However, since the position compensating member 568, that is, the universal joint is disposed in the middle of the second rotation shaft 524c and the second driving force transmission gear 562, the position compensating member 568 changes up and down of the second rotation shaft 524c. To compensate. Therefore, the engagement position of the first driving force transmission gear 561 and the second driving force transmission gear 562 can also be kept constant.

In addition, when the first driving force transmission gear 561 and the second driving force transmission gear 562 are coupled, the first positioning member 563 formed on the first driving force transmission gear 561 may be provided to the second driving force transmission gear 562. The second positioning member 564 may be connected in a rolling manner. Therefore, the combined position of the first driving force transmission gear 561 and the second driving force transmission gear 562 may be kept constant by the first positioning member 563 and the second positioning member 564.

For example, when the driving force transmission gears 561 and 562 are coupled in too close a position, since the gear values of the driving force transmission gears 561 and 562 mesh deeply with each other, the backlash of the driving force transmission gears 561 and 562 The backlash is reduced so that the driving force transmission gears 561 and 562 can be abnormally operated. At this time, since the first positioning member 563 and the second positioning member 564 restrict the coupling position of the first driving force transmission gear 561 and the second driving force transmission gear 562, the first driving force transmission. The engagement position of the gear 561 and the second driving force transmission gear 562 can be prevented from being arbitrarily changed in accordance with the position change of the second rotation shaft 524c.

19 and 20 are a perspective view and a plan view of the lower portion of the transfer unit in the printing apparatus according to another embodiment of the present invention, Figures 21 and 22 are transfer units in the printing apparatus according to another embodiment of the present invention The top of the is a perspective view shown.

In Figs. 19 to 22, the same reference numerals as those shown in Figs. 1 to 6 denote the same members. Hereinafter, descriptions will be made mainly on points different from the printing apparatus 100 illustrated in FIGS. 1 to 6.

19 to 22, a printing apparatus according to still another embodiment of the present invention differs from the printing apparatus 100 illustrated in FIGS. 1 to 6 in that the transfer unit for transferring the to-be-printed object P ( The configuration of 620 and 650 is different.

The

transfer units

620 and 650 form a transfer passage 114 of the casing to transfer the to-be-printed object P. The conveying

units

620 and 650 form a lower portion of the conveying passage 114 and form an upper portion of the conveying passage 114, the first conveying unit 620 for conveying the to-be-printed object P, and the first conveying unit. The second transfer unit 650 may be elastically in close contact with the 620. The

transfer units

620 and 650 may be formed of a plurality of rollers and belts.
