Disclosure of Invention
Problems to be solved by the invention
When the driving substrate is driven, the driving substrate generates heat. On the other hand, if the temperature of the ejection portion is increased, there may be an adverse effect such as the nozzle which ejects the liquid being easily clogged. In addition, since the drive substrate is generally provided in the vicinity of the ejection portion, it is desirable that heat generated by driving the drive substrate is not transmitted to the ejection portion.
Therefore, an object of the present invention is to suppress heat of a drive substrate from being transmitted to an ejection portion.
Means for solving the problems
A liquid discharge device according to a first aspect of the present invention for solving the above problems includes: an ejection section for ejecting liquid; a discharge portion accommodating portion for accommodating the discharge portion; a drive substrate for driving the ejection section; and a drive substrate accommodating portion provided separately from the ejection portion accommodating portion and accommodating the drive substrate.
According to this aspect, the ejection portion accommodating portion for accommodating the ejection portion and the drive substrate accommodating portion for accommodating the drive substrate for driving the ejection portion are arranged as independent bodies. Therefore, heat of the drive substrate can be prevented from being transmitted to the ejection portion.
A liquid discharge device according to a second aspect of the present invention is the liquid discharge device according to the first aspect, wherein a liquid flow path for supplying the liquid to the discharge portion is provided, and the liquid flow path is not disposed in the drive substrate housing portion, and is connected to the discharge portion via the discharge portion housing portion.
If liquid leaks from the liquid flow path and the liquid adheres to the drive substrate, the drive substrate may be short-circuited. When heat of the driving substrate is transmitted to the liquid flowing through the liquid flow path, physical properties such as viscosity of the liquid are changed, and the ejection stability of the liquid from the ejection portion may be lowered. On the other hand, according to the present embodiment, the liquid flow path is not disposed in the drive substrate accommodating portion, but is connected from the liquid accommodating portion or the like to the ejection portion via the ejection portion accommodating portion. Therefore, it is possible to suppress the liquid flowing through the liquid flow path from adhering to the drive substrate or the heat of the drive substrate from being transmitted to the liquid flowing through the liquid flow path.
A liquid discharge device according to a third aspect of the present invention is the liquid discharge device according to the first or second aspect, wherein the discharge portion accommodating portion and the drive substrate accommodating portion are connected by a connector terminal provided in the discharge portion accommodating portion and a connector terminal provided in the drive substrate accommodating portion.
If the transmission distance of the signal (data) between the ejection unit and the drive substrate becomes long, there is a possibility that transmission loss occurs when the signal is transmitted. However, according to this aspect, since the ejection section housing section and the drive substrate housing section are connected by the connector terminal provided in the ejection section housing section and the connector terminal provided in the drive substrate housing section (not connected by the cable having a long transmission distance), the transmission distance of the signal between the ejection section and the drive substrate can be shortened. This can suppress transmission loss in signal transmission.
A liquid discharge device according to a fourth aspect of the present invention is the liquid discharge device according to the third aspect, wherein the discharge portion and the connector terminal provided in the discharge portion housing portion are connected by a flexible flat cable, and the drive substrate and the connector terminal provided in the drive substrate housing portion are connected by a flexible flat cable.
According to this aspect, the ejection section and the connector terminal provided in the ejection section housing section are connected by a flexible flat cable, and the drive substrate and the connector terminal provided in the drive substrate housing section are connected by a flexible flat cable. Therefore, the ejection section and the connector terminal provided in the ejection section housing section, and the drive substrate and the connector terminal provided in the drive substrate housing section can be connected by a simple structure.
A liquid discharge device according to a fifth aspect of the present invention is the liquid discharge device according to any one of the first to fourth aspects, wherein the drive substrate is provided so as not to face the discharge portion.
According to this aspect, the drive substrate is disposed so as not to face the ejection portion. Therefore, the heat generated by the drive substrate can be effectively prevented from being transmitted to the ejection portion.

Detailed Description
A recording apparatus according to an embodiment of the liquid ejecting apparatus of the present invention will be described in detail below with reference to the drawings.
First, an outline of the recording apparatus 1 according to an embodiment of the present invention will be described.
Fig. 1 is a schematic perspective view of a recording apparatus 1 of the present embodiment. Fig. 2 is a schematic plan view of the recording apparatus 1 of the present embodiment. Fig. 3 is a schematic front view of the recording apparatus 1 of the present embodiment. Fig. 4 is a schematic side view of the recording apparatus 1 of the present embodiment. Fig. 5 is a schematic rear view of the recording apparatus 1 of the present embodiment. Fig. 1 to 5 show a state in which a part of the constituent members is removed from the recording apparatus 1 of the present embodiment, for example, a state in which the sub carriage 5 (see fig. 6 to 10) is removed from the carriage 6.
The recording apparatus 1 of the present embodiment includes a conveying mechanism 3, and the conveying mechanism 3 conveys a recording medium (medium) in a conveying direction a by an adhesive tape 2 (endless belt) that supports the recording medium by a support surface to which an adhesive is adhered. Further, a non-illustrated extracting unit is provided, to which a roll-shaped recording medium can be attached, and which can extract the recording medium to the conveying mechanism 3. Further, the recording mechanism 4 is provided, and the recording mechanism 4 performs recording by reciprocating scanning a carriage 6 provided with a recording head 7 as a discharge portion in a reciprocating direction B intersecting the conveying direction a of the recording medium in a region where the recording medium is conveyed by the conveying mechanism 3. A winding mechanism, not shown, is provided, and the winding mechanism can wind the recording medium recorded in the recording mechanism 4.
The conveying mechanism 3 of the present embodiment includes: an adhesive tape 2 for carrying and transporting the recording medium drawn out from the drawing section; a driving roller 8 and a driven roller 9, the driving roller 8 and the driven roller 9 moving the adhesive tape 2. The recording medium is attached to and placed on the support surface of the adhesive tape 2.
However, the endless belt as the transport belt is not limited to the adhesive belt. For example, an electrostatic adsorption type endless belt may be used.
The recording apparatus 1 of the present embodiment is provided with the transport mechanism 3 having the above-described configuration, but is not limited to the transport mechanism having the above-described configuration, and may be configured to support and transport the recording medium by a movable support tray or the like, or configured to transport the recording medium by a roller or the like. Further, the recording apparatus may be a so-called tablet type recording apparatus in which a recording medium is fixed to a support portion and recording is performed by moving the recording head 7 with respect to the fixed recording medium.
The recording mechanism 4 includes a carriage motor 30 (see fig. 15), and the carriage motor 30 reciprocates a carriage 6 including a recording head 7 capable of ejecting ink (liquid) in a reciprocating direction B.
The recording apparatus 1 of the present embodiment performs recording by reciprocating scanning the carriage 6 including the recording head 7 during recording, but the conveying mechanism 3 stops conveying the recording medium during recording scanning (during movement of the carriage 6). In other words, at the time of recording, the reciprocating scanning of the carriage 6 and the conveyance of the recording medium are alternately performed. That is, at the time of recording, the transport mechanism 3 intermittently transports the recording medium (intermittently moves the adhesive tape 2) in accordance with the reciprocating scanning of the carriage 6.
Although the recording apparatus 1 of the present embodiment includes the recording head 7 that performs recording while performing reciprocating movement, it may be a recording apparatus including a so-called line head in which a plurality of nozzles for ejecting ink are provided in a direction intersecting the transport direction a.
Here, the "line head" refers to a recording head used in a recording apparatus which is provided so that a region of a nozzle formed in a crossing direction crossing a transport direction a of a recording medium can cover the entire crossing direction of the recording medium and relatively moves the recording head or the recording medium to form an image. Further, the nozzle area in the intersecting direction of the line head may not cover the entire intersecting direction of all the recording media corresponding to the recording apparatus.
Further, a track 10a extending in the reciprocating direction B is formed on a duct 11a constituting the skeleton portion of the recording apparatus 1 of the present embodiment, and a track 10B extending in the reciprocating direction B is formed on a duct 11B constituting the skeleton portion of the recording apparatus 1 of the present embodiment. Further, the movement of the carriage 6 in the reciprocating direction B in the present embodiment is guided by the rails 10a and 10B by receiving bearing portions, not shown, in the rails 10a and 10B.
A blowing portion 12 is provided at a lower position of the duct 11B, and the blowing portion 12 extends in the reciprocating direction B and blows air in a direction opposite to the conveying direction a from a plurality of blowing ports, not shown. A mist recovery unit 13 is provided at a lower position of the duct 11a, and the mist recovery unit 13 extends in the reciprocating direction B and is capable of recovering the ink mist ejected from the recording head 7. Further, the mist recovery unit 13 is provided with a recovery port 16, and the recovery port 16 extends in the reciprocating direction B at a lower position of the duct 11 a.
As shown in fig. 3, a plurality of (three) exhaust fans 14 for generating the blowing force by the blowing unit 12 are provided on the downstream side in the transport direction a of the recording apparatus 1 of the present embodiment. The air blowing unit 12 can blow air from the outside of the recovery unit 13 (at a position downstream in the conveyance direction a) to the recovery port 16 by the blowing force generated by the exhaust fan 14. As shown in fig. 5, a plurality of (three) suction fans 15 as suction portions for generating air flows from the recovery port 16 to the inside of the recovery portion 13 and further from the inside of the recovery portion 13 to the outside of the recording apparatus 1 are provided on the upstream side in the transport direction a of the recording apparatus 1 according to the present embodiment.
Next, a carriage 6 which is a main part of the recording apparatus 1 of the present embodiment and a sub-carriage 5 mounted on the carriage 6 will be described.
Here, fig. 6 is a schematic front view of the carriage 6. Fig. 7 is a schematic side perspective view of the sub carriage 5. Fig. 8 is a schematic perspective view of the sub carriage 5. Fig. 9 is a schematic perspective view of the sub carriage 5 with the housings 22 and 45 removed.
As shown in fig. 6, the carriage 6 of the present embodiment is configured to be able to mount a plurality of sub-carriages 5 and perform reciprocating scanning in the reciprocating direction B.
As shown in fig. 7, the sub carriage 5 includes: a discharge portion housing section 20 in which the recording head 7 is housed; and a drive substrate accommodating portion 19 accommodating a drive substrate 40 for driving the recording head 7. The drive substrate housing section 19 and the ejection section housing section 20 are connected by a connection section 38 (connector terminal) on the drive substrate housing section 19 side and a connection section 39 (connector terminal) on the ejection section housing section 20 side. Further, the drive substrate 40 and the connection portion 38 are connected by an FFC (flexible flat cable) 43, and the recording head 7 and the connection portion 39 are connected by an FFC 44.
As shown in fig. 8, the drive substrate accommodating portion 19 includes a case 22, and the ejection portion accommodating portion 20 includes a case 45. In order to suppress the temperature rise (heat accumulation) inside the drive substrate housing portion 19 caused by the heat generation of the drive substrate 40, a plurality of holes 48 are provided in the case 22.
As shown in fig. 9, the drive substrate housing 19 includes a heat transfer plate 21, and the heat transfer plate 21 is in contact with the casing 22 and the drive substrate 40 inside the casing 22 to easily transfer heat of the drive substrate 40 to the casing 22.
As shown in fig. 8 and 9, an ink flow path 46 (liquid flow path) is provided inside the ejection unit housing portion 20, and the ink flow path 46 is used to supply ink from an ink cartridge (liquid housing portion) not shown to the recording head 7. In the sub-carriage 5, the ink flow path 46 is formed only in the ejection portion housing portion 20 (not in the drive substrate housing portion 19, but only in the ejection portion housing portion 20) without passing through the drive substrate housing portion 19.
As shown in fig. 8 and 9, a projection 42 is formed on the ejection portion accommodating portion 20, and a fitting portion 41 to be fitted to the projection 42 is formed on the drive substrate accommodating portion 19. A handle 49 is formed on the drive substrate accommodating portion 19 on the side opposite to the side connected to the ejection portion accommodating portion 20 (the side C in the vertical upward direction). With the above configuration, the sub-carriage 5 of the present embodiment can easily connect the ejection part housing part 20 and the drive substrate housing part 19, and can easily remove the drive substrate housing part 19 from the ejection part housing part 20.
Next, the ejection section accommodating section 20 of the sub carriage 5 will be described in further detail.
Here, fig. 10 is a schematic side sectional view of the sub carriage 5, and the inside of the drive substrate housing section 19 is omitted. Fig. 11 is a schematic perspective view of the ejection portion housing 20. Fig. 12 is a schematic perspective view of the ejection unit housing 20 with the housing 45 removed. Fig. 13 is a partial schematic perspective view of the ejection unit housing 20 in a state where the sub head unit 47 is removed from the ejection unit housing 20. Fig. 14 is a partially schematic perspective view of the ejection section accommodating section 20.
As shown in fig. 10, 12, 13, and 14, the ejection portion housing portion 20 of the present embodiment includes a plate-shaped portion 36 and a heat transfer plate 37. As shown in fig. 10, the FFC44 is connected to the connection portion 39 in a state of being in contact with the plate-shaped portion 36, the plate-shaped portion 36 is in contact with the heat transfer plate 37, and the heat transfer plate 37 is in contact with the casing 45. With the above configuration, the heat of the FFC44 (and the recording head 7) can be transferred (released) to the case 45.
As shown in fig. 12 to 14, the ejection portion housing portion 20 of the present embodiment is configured to be removable as a unit from the head unit 47 in which a set of four recording heads 7 is provided. Further, as shown in fig. 13, a mounting hole 50 corresponding to the recording head 7 of the recording head 7 is formed in the bottom portion of the ejection portion housing portion 20. As shown in fig. 14, the head unit 47 can be fixed to the ejection portion accommodating portion 20 by screwing and fixing the head unit 47 by the screw fixing portion 51.
Next, an electrical structure of the recording apparatus 1 of the present embodiment is explained.
Fig. 15 is a block diagram of the recording apparatus 1 of the present embodiment.
The control unit 23 is provided with a CPU24 for controlling the entire recording apparatus 1. The CPU24 is connected to a ROM26 in which various control programs executed by the CPU24 and the like are stored and a RAM27 capable of temporarily storing data, via a system bus 25.
The CPU24 is connected to a head driving unit 28 for driving the recording head 7 via the system bus 25.
The CPU24 is connected to a motor driving unit 29 for driving the carriage motor 30, the transport motor 31, the pull-out motor 32, the winding motor 33, the exhaust fan motor 17, and the suction fan motor 18 via the system bus 25.
Here, the carriage motor 30 is a motor for moving the carriage 6 including the recording head 7. The conveyance motor 31 is a motor for driving the drive roller 8. The extracting motor 32 is a drive motor of an extracting unit for feeding the recording medium M set in an extracting unit, not shown, to the transport mechanism 3. The winding motor 33 is a drive motor that drives a winding mechanism, not shown, to wind the recording medium M on which recording is performed. The fan motor 17 is a motor for driving the fan 14. The suction fan motor 18 is a motor for driving the suction fan 15.
Further, the CPU24 is connected to the input/output unit 34 via the system bus 25, and the input/output unit 34 is connected to a PC35 for transmitting and receiving data such as recording data and signals.
Here, in summary, the recording apparatus 1 of the present embodiment includes: a recording head 7 for ejecting ink; a discharge portion accommodating portion 20 for accommodating the recording head 7; a drive substrate 40 for driving the recording head 7; and a drive substrate accommodating portion 19 provided separately from the ejection portion accommodating portion 20 and accommodating the drive substrate 40. That is, the ejection portion accommodating portion 20 for accommodating the recording head 7 and the drive substrate accommodating portion 19 for accommodating the drive substrate 40 for driving the recording head 7 are arranged as independent bodies. Therefore, heat of the drive substrate 40 can be suppressed from being transmitted to the recording head 7.
In the recording apparatus 1 of the embodiment, the position of the control section 23 as a control board (a board for controlling the driving of the entire recording apparatus 1) is not clearly defined, but may be provided in the driving board housing section 19, for example.
The recording apparatus 1 of the present embodiment includes an ink flow path 46 for supplying ink to the recording head 7, and the ink flow path 46 is not disposed in the drive substrate housing section 19, but is connected to the recording head 7 from an ink cartridge not shown via the ejection section housing section 20.
If ink leaks from the ink flow path 46 and the ink adheres to the drive substrate 40, the drive substrate 40 may be short-circuited. When the heat of the drive substrate 40 is transmitted to the ink flowing through the ink flow path 46, the physical properties such as the viscosity of the ink are changed, and the ejection stability of the ink from the recording head 7 may be lowered. On the other hand, in the recording apparatus 1 of the present embodiment, the ink flow path 46 is not disposed in the drive substrate housing section 19, but is connected to the recording head 7 from an ink cartridge not shown via the ejection section housing section 20. Therefore, it is possible to suppress the ink flowing through the ink flow path 46 from being attached to the drive substrate 40 or the heat of the drive substrate 40 from being transmitted to the ink flowing through the ink flow path 46.
As described above, in the recording apparatus 1 of the present embodiment, the ejection section accommodating section 20 and the drive substrate accommodating section 19 are connected by the connector terminal (connection section 39) provided in the ejection section accommodating section 20 and the connector terminal (connection section 38) provided in the drive substrate accommodating section 19.
If the transmission distance of the signal (data) between the recording head 7 and the drive substrate 40 becomes long, there is a possibility that a transmission loss occurs when the signal is transmitted. However, in the recording apparatus 1 of the present embodiment, the ejection section accommodating section 20 and the drive substrate accommodating section 19 are connected by the connector terminal (connection section 39) provided in the ejection section accommodating section 20 and the connector terminal (connection section 38) provided in the drive substrate accommodating section 19 (not connected by a cable having a long transmission distance), and therefore the transmission distance of signals between the recording head 7 and the drive substrate 40 can be shortened. This suppresses transmission loss when transmitting signals.
As shown in fig. 7 and the like, in the recording apparatus 1 of the present embodiment, the recording head 7 and the connection portion 39 provided in the ejection portion housing portion 20 are connected by the FFC44, and the drive board 40 and the connection portion 38 provided in the drive board housing portion 19 are connected by the FFC 43. With the above configuration, the recording head 7 and the connection portion 39 provided in the ejection portion housing portion 20, and the drive substrate 40 and the connection portion 38 provided in the drive substrate housing portion 19 can be connected to each other with a simple configuration.
As shown in fig. 7 and 9, the drive substrate 40 of the present embodiment is disposed along the direction of the recording head 7 with respect to the drive substrate 40 (the direction along the vertical upward direction C). In other words, the drive substrate 40 of the present embodiment is disposed in a configuration not facing the recording head 7. Therefore, the heat generated by the drive substrate 40 is effectively suppressed from being transmitted to the recording head 7.
The present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention.
