Description

[Technical field]

[0001] The present invention relates to a printing device in which a printing fluid stored in a tank is ejected by a print head onto a printing medium, and the printing medium is cut by a cutter. [Background technology]

[0002] There is known a printing device in which printing fluid stored in a tank is ejected from a print head onto a printing medium (see Patent Document 1). One example of a printing medium is a long sheet that is continuous in the transport direction. After printing, the sheet is cut by a cutter into, for example, a plurality of print units as a single unit. The sheet is composed of, for example, labels and release paper. For example, one print unit is printed on each label, and each label is peeled off the release paper from the cut sheet and affixed to a product or the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6291854 Summary of the Invention [Problem to be solved by the invention]

[0004] The printed sheet can be easily removed, for example, if it is discharged to the front of the printing device. Also, when filling the tank with printing fluid or replacing the tank, it is easy to operate if the tank can be accessed from the front of the printing device. Also, when replacing the cutter, it is easy to maintain if the cutter can be accessed from the front or above the printing device. In this way, if the sheet or tank can be accessed from a specific direction with respect to the printing device, a user-friendly printing device is realized.

[0005] However, if an opening through which the sheet passes and an access path to the tank are provided on a specific surface of the printing device so that the sheet and the tank can be accessed from a specific direction, the area of ​​the specific surface of the printing device will increase, resulting in a larger device.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a printing device that allows access to sheets and tanks from a specific direction relative to the printing device, thereby enabling the device to be made thinner and more compact. [Means for solving the problem]

[0007] (1) A printing device according to the present invention includes a housing, a conveying means located in an internal space of the housing and conveying a printing medium in a conveying direction, a print head located downstream of the conveying means in the conveying direction and discharging a printing fluid onto the printing medium conveyed by the conveying means, a tank at least a part of which is located in the internal space of the housing and accessible from downstream of the housing in the conveying direction, for storing the printing fluid to be supplied to the print head, a passage opening in the housing facing downstream in the conveying direction, through which the printing medium onto which the printing fluid has been discharged from the print head passes, and a cutter unit for cutting the printing medium onto which the printing fluid has been discharged from the print head. The cutter unit has a carriage movable in a scanning direction intersecting the conveying direction, and a cutter mounted on the carriage. In an orthogonal direction perpendicular to the conveying direction and the scanning direction, at least a part of the passage opening is in the same position as the tank. In the orthogonal direction, at least a part of the cutter unit is in the same position as the tank. The tank is located away from the passage opening in one direction in the scanning direction, and the carriage is located away from the passage opening in the other direction in the scanning direction in a standby state.

[0008] According to the above configuration, the dimensions of the printing device in the orthogonal direction are reduced to achieve a slim design, while the dimensions in the scanning direction are reduced to reduce the installation area. In addition, the tank and the print medium after printing can be accessed from downstream in the transport direction relative to the housing.

[0009] (2) Preferably, the cutter unit is located in an internal space of the housing, and the housing has an exposure opening that exposes the cutter to the outside when the carriage is in the standby state, and a cover that opens and closes the exposure opening.

[0010] When the cover is opened and the exposure port is exposed, the cutter mounted on the carriage can be replaced.

[0011] (3) Preferably, the printing device further includes a holder located upstream of the housing in the transport direction, the holder having a storage space for storing the printing medium wound in a roll shape with the scanning direction as an axis of rotation, and a tray rotatably connected to the housing around an axis along the scanning direction and moving between a first position and a second position, the axis of the tray being located downstream in the transport direction from the axis of rotation of the printing medium stored in the storage space, the second position being a position where the tray is tilted downstream in the transport direction from the first position, and the tray in the second position overlaps with the storage space when viewed from the perpendicular direction.

[0012] When viewed from the orthogonal direction, the tray in the second position overlaps with the storage space of the holder, thereby reducing the size of the printing device in the transport direction. Also, since the tray in the first position is not tilted down as much as the tray in the second position, by placing the tray in the first position, it becomes easier to load the print medium into the storage space.

[0013] (4) Preferably, the tank is located to the right of the passage opening when viewed from downstream to upstream in the conveying direction, and the carriage in a standby state is located to the left of the passage opening when viewed from downstream to upstream in the conveying direction.

[0014] Since the tank is accessed more frequently than the cutter is replaced, the tank is conveniently located to the right of the passage opening.

[0015] (5) Preferably, an operation panel having an operation surface for receiving input to the printing device is provided in the housing at a position at least partially coincident with the passage opening in the perpendicular direction, the operation surface facing downstream in the transport direction.

[0016] The operation panel can be accessed from downstream in the conveying direction, making it easy to use.

[0017] (6) Preferably, the carriage is located downstream of the operation panel in the transport direction.

[0018] The operation panel is less likely to interfere when accessing the carriage through the exposure opening.

[0019] (7) Preferably, the print head is located upstream of the tank in the transport direction.

[0020] (8) Preferably, the tank has an inlet facing downstream in the transport direction, and the printing fluid can be replenished through the inlet.

[0021] (9) Preferably, the tank is removable from the housing toward the downstream in the conveying direction. Effect of the Invention

[0022] According to the present invention, it is possible to access the sheet and the tank from a specific direction with respect to the printing device, and it is also possible to realize a thinner and more compact printing device. [Brief description of the drawings]

[Diagram 3] FIG. 3 is a perspective view of the rear surface 14B side of the printing device 10 with the support wall 22 removed. [Figure 4] FIG. 4 is a perspective view of the rear 14B side of the printing device 10 with the roll paper 11 stored in the holder 15 partially pulled out from the rotating shaft 23. FIG. [Diagram 5] FIG. 5 is a schematic diagram showing the internal configuration of the printing device 10. As shown in FIG. [Figure 6] FIG. 6 is a schematic diagram showing the configuration of the cutter unit 18. As shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] A printing device 10 according to an embodiment of the present invention will be described below. Note that the embodiment described below is merely one example of the present invention, and it goes without saying that the embodiment can be modified as appropriate without changing the gist of the present invention. In the following description, the direction is expressed as the progress from the starting point of the arrow to the end point, and the direction is expressed as the movement on the line connecting the starting point and the end point of the arrow. In the following description, the up-down direction 7 is defined based on the state in which the printing device 10 is installed so that it can be used (the state in FIG. 1), the front-rear direction 8 is defined with the side where the passage opening 13 is provided as the front side (front), and the left-right direction 9 is defined when the printing device 10 is viewed from the front side (front).

[0025] [Overall configuration of the printing device 10] 1, the printer 10 records an image on roll paper 11 (see FIGS. 1 to 4: an example of a print medium) using an inkjet recording method. The housing 14 is a roughly rectangular parallelepiped shape with a passage opening 13 formed on the front surface 14A.

[0026] A holder 15 capable of storing roll paper 11 is located at the rear of the housing 14. A tray 20 extends upward from the rear surface of the housing 14. An operation panel 17 is located on the front surface 14A of the housing 14. Below the operation panel 17, a protrusion 16 is located, which is a part of the housing 14 that protrudes forward. The protrusion 16 is a rectangular parallelepiped that is elongated with its longitudinal direction in the left-right direction 9. A cutter unit 18 (see FIG. 6) is located in the internal space of the protrusion 16.

[0027] [Holder 15] 2 to 4, the holder 15 has support walls 21, 22 spaced apart in the left-right direction 9, a rotation shaft 23 extending across the support walls 21, 22, and a bottom plate 25 connecting the support walls 21, 22.

[0028] The support walls 21 and 22 each extend rearward from the rear surface 14B of the housing 14. A bottom plate 25 extends across the rear surface 14B of the housing 14 and the lower ends of the support walls 21, 22. The bottom plate 25 connects the rear surface 14B of the housing 14 with the support walls 21, 22. The space surrounded by the rear surface 14B of the housing 14, the support walls 21, 22, and the bottom plate 25 is the storage space 26. The storage space 26 stores the roll paper 11.

[0029] The rotating shaft 23 is a cylindrical member that is inserted into a space that extends along the center of the paper roll 11. Both ends of the rotating shaft 23 are rotatably supported by the support walls 21, 22, respectively. The rotating shaft 23 is inserted through the paper roll 11 and supported by the support walls 21, 22 in a state in which the rotating shaft 23 extends in the left-right direction 9. This causes the paper roll 11 to be stored in the storage space 26 of the holder 15. The paper roll 11 stored in the holder 15 enters the internal space of the housing 14 through an opening 27 (see FIG. 5) formed in the rear surface 14B of the housing 15.

[0030] [Tray 20] A tray 20 is provided on the rear side of the printing device 10. The tray 20 supports a plurality of rectangular sheets of recording paper separately from the holder 15. The tray 20 is rotatably supported by the housing 14 with its lower end as a rotation base end and its upper end as a rotation tip end. As shown in FIG. 5, near the lower ends of both sides of the tray 20, rotation shafts 20A protruding outward in the left-right direction 9 are provided, and the rotation shafts 20A are fitted into bearings of the housing 14, thereby enabling the tray 20 to rotate around an axis 30 (see FIG. 2). As shown in FIG. 2, the axis 30 is located forward of the rotation shaft 23 of the holder 15.

[0031] The tray 20 is rotatable between an upright position (an example of a first position) shown in Fig. 1 and a laid-down position (an example of a second position) shown in Fig. 5. The upright position is a position for reducing the space occupied by the tray 20 behind the housing 14 in the front-rear direction 8 when the tray 20 is not in use. The rear surface of the tray 20 in the upright position is approximately parallel to the rear surface 14A of the housing 14. The laid-down position is a position in which the tray 20 is inclined diagonally upward toward the rear from the housing 14. For example, the front and back surfaces of a single sheet of recording paper (an example of a print medium) supported by the tray 20 in the laid-down position intersect with the vertical direction.

[0032] As shown in FIG. 1, a pair of side guides 32 are provided on the front surface of the tray 20. The side guides 32 are positioned apart in the left-right direction 9. The side guides 32 position the recording paper in the left-right direction 9 by contacting both ends of the recording paper supported on the front surface of the tray 20 in the left-right direction 9. The tray 20 is also provided with an extension tray 29 that is housed in an internal space and extends from the upper end when the tray 20 is pulled out. When the extension tray 29 is pulled out from the internal space of the tray 20, it protrudes upward from the front surface of the tray 20, and the extension tray 29 supports the recording paper. When the extension tray 29 is housed in the internal space of the tray 20, the external shape of the tray 20 is reduced.

[0033] 5, recording paper supported by tray 20 in the collapsed position enters the internal space of housing 14 through opening 31. The position of tray 20 can be arbitrarily selected by a user's operation. A portion of the upper end side of tray 20 in the collapsed position overlaps with storage space 26 of holder 15 when viewed along the up-down direction 7.

[0034] [Operation Panel 17] 1, operation panel 17 is located above protrusion 16 on front surface 14A of housing 14. The front surface of operation panel 17 is operation surface 17A. A display 33, operation keys 34, a power button 35, etc. are located on operation surface 17A. Operation surface 17A generally faces forward, but for example, even if it faces forward and upward, operation panel 17 may be rotatable with respect to housing 14, so that the orientation of operation surface 17A can be changed.

[0035] [Transportation Route 65] As shown in Fig. 5, the transport path 65 provided in the internal space of the housing 14 extends generally straight from the opening 27 formed in the rear surface 14B toward the passage opening 13 formed in the protruding portion 16. The transport path 65 is partitioned by guide members and the like positioned apart in the up-down direction 7. The portion extending from the roll paper 11 and the recording paper pass through the transport path 65. In Fig. 5, the transport path 65 downstream of the first transport roller pair 54 in the transport direction is indicated by a two-dot chain line.

[0036] [Bypass Route 66] 5, a bypass path 66 provided in the internal space of the housing 14 extends forward and downward from an opening 31 formed in the rear surface 14B, and continues to a position behind the first pair of transport rollers 54 of the transport path 65. The bypass path 66 is defined by guide members and the like positioned apart in the up-down direction 7. Recording paper supported by the tray 20 passes through the bypass path 66.

[0037] [First conveyor roller pair 54 and second conveyor roller pair 55] As shown in FIG. 5, a first transport roller pair 54 (an example of a transport means) is provided on the transport path 65 upstream of the recording unit 24 in the transport direction (forward in the front-rear direction 8). The first conveying roller pair 54 has a first conveying roller 60 and a pinch roller 61. In the conveying path 65, a second conveying roller pair 55 is provided downstream of the recording unit 24 in the conveying direction. The second conveying roller pair 55 has a second conveying roller 62 and a spur 63. The first conveying roller 60 and the second conveying roller 62 rotate by the rotation of a motor (not shown). The first conveying roller pair 54 and the second conveying roller pair 55 convey the roll paper 11 or the recording paper by rotating the first conveying roller 60 and the second conveying roller 62 with the portion extending from the roll paper 11 or the recording paper sandwiched between the respective rollers that constitute the first conveying roller pair 54 and the second conveying roller pair 55.

[0038] [Record 24] 5, the recording unit 24 is provided above the conveying path 5, facing the platen 42, between the first conveying roller pair 54 and the second conveying roller pair 55. The recording unit 24 includes a head carriage 41 and a print head 39. The head carriage 41 is supported by carriage guide rails 43, 44 provided on the rear and front sides of the platen 42. A known belt mechanism is provided on the carriage guide rail 44. The head carriage 41 is connected to an endless belt of the belt mechanism, and moves in the left-right direction 9 along the carriage guide rails 43, 44 by the rotation of the endless belt.

[0039] The print head 39 is mounted on a head carriage 41. A number of nozzles (not shown) are formed on the underside of the print head 39. Ink (an example of a printing fluid) is supplied to the print head 39 from a tank 70 through a tube 71. The print head 39 selectively ejects ink as tiny ink droplets from the multiple nozzles. As the head carriage 41 moves in the left-right direction 9, ink droplets are ejected from the nozzles onto the roll paper 11 or recording paper supported by the platen 42. The ejected ink droplets adhere to the roll paper 11 or recording paper on the platen 42, recording images or characters on part of the roll paper 11 or on the recording paper.

[0040] [Tank 70] As shown in FIG. 5, the tank 70 is located in the internal space of the housing 14. The tank 70 is a hollow container that stores ink. The tank 70 has a plurality of storage spaces that store, for example, black, yellow, cyan, and magenta pigment inks, respectively. An inlet 72 is formed near the upper end of the front surface of the tank 70. Ink can be refilled into the storage spaces of the tank 70 through the inlet 72. The inlet 72 is provided for each storage space. Although not shown in the figure, the inlet 72 is sealed with a cap, and ink can be refilled from the inlet 72 by removing the cap. The tank 70 is located forward of the print head 39, that is, downstream in the transport direction.

[0041] As shown in FIG. 1, a cover 73 is provided on the right side of the front surface 14A of the housing 14 in the left-right direction 9. The cover 73 is located to the right of the protrusion 16. The cover 73 is rotatable around a rotation axis 73A along the left-right direction 9 near the lower end. That is, the cover 73 is rotatably connected to the housing 14. As shown in FIG. 1, the cover 73 in the closed position constitutes the front surface 14A of the housing 14. The tank 70 is located behind the cover 73. That is, the tank 70 is located away from the passage opening 13 to the right.

[0042] By rotating the cover 73 around the rotation shaft 73A, the upper end side of the cover 73 moves forward, and at least the vicinity of the inlet 72 of the tank 70 in the internal space of the housing 14 is exposed. In other words, when the cover 73 is in the open position, the tank 70 is accessible from the front of the housing 14. "Access to the tank 70" means that a cap sealing the inlet 72 can be removed from the outside of the housing 14, and ink can be refilled into the storage space of the tank 70 through the inlet 72. Note that the entire tank 70 does not necessarily have to be located in the internal space of the housing 14. The rotation shaft 73A of the cover 73 may be aligned along the up-down direction 7.

[0043] [Passing port 13] As shown in FIG. 1, the passage opening 13 is a long and narrow opening on the front surface of the convex portion 16, with its longitudinal direction being the left-right direction 9. The passage opening 13 is the end of the transport path 65. From the passage opening 13, a portion of the roll paper 11 and recording paper after printing are discharged to the outside. As shown in FIG. 5, the passage opening 13 is in the same position as the tank 70 in the vertical direction 7. The passage opening 13 is also located in a range L between the upper and lower ends of the tank 70 in the vertical direction 7.

[0044] [Cutter unit 18] As shown in Fig. 1, a protrusion 16 that protrudes forward is provided on the front surface of the housing 14. An exposure opening 12 is formed to the left of the passage opening 13 in the protrusion 16. The exposure opening 12 opens forward and upward, and the internal space of the protrusion 16 is exposed to the outside through the exposure opening 12. As shown in Figs. 1 and 2, the exposure opening 12 is closed by a cover 19. The exposure opening 12 is opened by the cover 19 being moved from the position where it closes the exposure opening 12 by rotation or the like. That is, the cover 19 opens and closes the exposure opening 12.

[0045] As shown in Fig. 6, cutter unit 18 is located in the internal space of protrusion 16. Cutter unit 18 cuts off a portion of the roll paper 11 that passes through passage opening 13 after printing. As shown in Fig. 5, cutter unit 18 is in the same position as tank 70 in the vertical direction 7. Also, cutter unit 18 is located in range L between the upper and lower ends of tank 70 in the vertical direction 7.

[0046] As shown in FIG. 6, the cutter unit 18 has a guide shaft 80 extending in the left-right direction 9, a cutter carriage 81 that moves along the guide shaft 80, and a cutter 82 mounted on the cutter carriage 81.

[0047] The guide shaft 80 is a rod-shaped member extending outward beyond both ends of the passage opening 13 in the left-right direction 9. The guide shaft 80 is supported by the side walls of the protrusion 16, etc. The cutter carriage 81 is supported by the guide shaft 80. Note that a cutter guide rail (not shown) extending parallel to the guide shaft 80 may be further provided, and the guide shaft 80 and the cutter guide rail may support the cutter carriage 81.

[0048] Although not shown in the figures, a known belt mechanism is provided along the guide shaft 80. The cutter carriage 81 is connected to an endless belt of the belt mechanism, and moves in the left-right direction 9 along the guide shaft 80 by the rotation of the endless belt. In other words, the left-right direction 9 is the scanning direction of the cutter carriage 81. In the standby state, that is, when the printing device is not printing, the cutter carriage 81 is located to the left of the guide shaft 80 and near the exposure opening 12, as shown in FIG. 6. This position is the standby position H. The standby position H is a position away from the passage opening 13 to the left (left when looking at the printing device 10 from the front).

[0049] The cutter 82 is mounted on the cutter carriage 81. The cutter 82 has a blade capable of cutting the roll paper 11 and the like. The tip of the blade of the cutter 82 faces to the right (to the right when looking at the printing device 10 from the front). When the cutter carriage 81 moves to the right from the standby position H, the blade of the cutter 82 comes into contact with a portion of the roll paper 11 after printing, and that portion of the roll paper 11 is cut off.

[0050] The cutter 82 is connected to the cutter carriage 81 by means of a screw (not shown) or the like. When the screw is removed, the cutter 82 can be removed from the cutter carriage 81. The cutter 82 has an outer shape that can pass through the exposure opening 12. When the cutter carriage 81 is in the standby position H, if the exposure opening 12 is opened, the cutter 82 can be removed from the cutter carriage 81 and taken out to the outside. Since the cutter carriage 81 in the standby position H is located forward of the operation panel 17, the cutter 82 can be taken out forward or upward through the exposure opening 12. The fact that the cutter 82 can be operated to be taken out is referred to as the cutter 82 being accessible.

[0051] [Effects of the embodiment] According to the printing device 10 of the embodiment described above, the passage opening 13 and cutter unit 18 are in the same position as the tank 70 in the vertical direction 7, the tank 70 is located away from the passage opening 13 to the right in the horizontal direction 9, and the cutter carriage 81 in standby position H is located away from the passage opening 13 to the left in the horizontal direction 9, so that the dimensions of the printing device 10 in the vertical direction 7 can be reduced to achieve a slimmer design, while the dimensions in the horizontal direction 9 can be made smaller, thereby reducing the installation area of ​​the printing device 10. Also, the tank 70 and part of the roll paper 11 after printing can be accessed from the front of the housing 14.

[0052] Furthermore, when the cover 19 is opened and the exposure opening 12 of the protrusion 16 is exposed, the cutter 82 mounted on the cutter carriage 81 in the standby position H can be replaced.

[0053] Furthermore, when viewed from the vertical direction 7, the tray 20 in the collapsed position overlaps with the storage space 26 of the holder 15, thereby reducing the dimension of the printing device 10 in the front-rear direction 8. Furthermore, the tray 20 in the upright position is less collapsed in the vertical direction 7 than the tray 20 in the collapsed position, so by placing the tray 20 in the upright position, it becomes easier to load the roll paper 11 into the storage space 20.

[0054] In addition, since the tank 70 is replenished with ink more frequently than the cutter 82 is replaced, the tank 70 is conveniently located to the right of the passage opening 13 (to the right when looking at the printing device 10 from the front), which makes it easier to use.

[0055] Furthermore, since the operation surface 17A of the operation panel 17 faces forward, the display 33 can be viewed and the operation keys 34 and power button 35 can be operated from the front of the printing device 10, making it easy to use.

[0056] In addition, since the cutter carriage 81 is located forward of the operation panel 17, when accessing the cutter carriage 81 through the exposure opening 12, the operation panel 17 is unlikely to interfere with the user's hand or the like.

[0057] [Variations] In the embodiment described above, the tank 70 is fixed to the internal space of the housing 14, and ink can be refilled into the storage space of the tank 70 through the inlet 72. Alternatively, the tank 70 may be a cartridge type that is detachable from the housing 14, and the cover 73 may be opened and the tank 70 may be removable forward from the housing 14.

[0058] Furthermore, the tank 70 has a plurality of storage spaces for storing the four colors of ink: black, yellow, cyan, and magenta; however, instead, the tank 70 may have only a single storage space for storing black ink.

[0059] The tank 70 stores black, yellow, cyan, and magenta pigment inks, but may store black pigment ink and yellow, cyan, and magenta dye inks instead. The tank 70 may store black, yellow, cyan, and magenta dye inks. The ink stored in the tank 70 may be, for example, a conductive ink in which metal particles are dispersed in a solvent. The tank 70 may have a storage space for storing black, yellow, cyan, and magenta inks, and a storage space for storing conductive ink.

[0060] Furthermore, the passage opening 13 and the cutter unit 18 may be partially located above or below the space between the upper and lower ends of the tank 70 in the vertical direction 7. That is, it is sufficient that the passage opening 13 and the cutter unit 18 are partially located between the tanks 70 in the vertical direction 7. Furthermore, the positions of the tank 70 and the standby position H of the cutter unit 18 in the left-right direction 9 may be reversed with respect to the passage opening 13. That is, the tank 70 may be located to the left of the passage opening 13, and the standby position H may be to the right of the passage opening 13.

[0061] In addition, the cutter unit 18 is provided in the internal space of the protrusion 16, but this is not limiting. For example, the cutter unit 18 may be provided in the internal space of the housing 14. When the cutter unit 18 is provided in the internal space of the housing 14 , the cutter unit 18 is located downstream of the print head 39 in the front-rear direction 8 .

[0062] Further, instead of the embodiment described above, the cutter 82 may be a disk-shaped cutter having a rotation axis along the front-rear direction 8.

[0063] Furthermore, the passage opening 13 does not necessarily have to be formed on the front surface 14A of the housing 14. For example, the passage opening 13 may be formed on the upper surface of the convex portion 16 or on the upper surface of the housing 14, and the printed roll paper 11 that passes through the passage opening 13 may be discharged diagonally upward or upward.

[0064] Furthermore, the print head 39 described above is a so-called serial head in which the head carriage 41 supported by carriage guide rails 43, 44 moves in the left-right direction 9 while ejecting ink onto the roll paper 11, etc., but the print head 39 has a width equal to or greater than the dimension of the roll paper 11 in the left-right direction 9, and may be a line head that ejects ink onto the roll paper 11, etc. without moving in the left-right direction 9. Furthermore, the print head 39 may be located so as to overlap with the tank 70 in the front-rear direction 8.

[0065] Furthermore, although the printing device 10 described above is capable of printing on both roll paper 11 and recording paper, this is not limited thereto, and the printing device 10 may be a device that prints only on roll paper 11, or a device that prints only on recording paper.

[0066] Furthermore, the printer 10 described above is used with the front surface 14A and rear surface 14B of the housing 14 aligned along the up-down direction 7 and left-right direction 9, but the usage position of the printer 10 is not limited to this. [Explanation of symbols]
