The ink tank 50 accommodates four types of ink (in this embodiment, each color ink of cyan ink, magenta ink, yellow ink, and black ink). Then, the ink supply tubes 44C, 44M, 44Y, and 44K, which are connecting tubes that form the flow paths of the respective inks, pass through the connection terminal 43 provided at one end thereof, from the opening hole 14b provided in the device housing 14 to the device. Each ink is supplied in the main body 12 separately. In the following description, when the ink supply tubes 44C, 44M, 44Y, and 44K are collectively referred to without distinguishing them, they are referred to as ink supply tubes 44 . the

In the printer 11, the respective inks of the ink tanks 50 supplied from the ink tanks 50 to the apparatus main body 12 are supplied from the ink tanks 50 to the recording unit 20 through the ink supply tubes 44, and constitute inks that consume the supplied inks in the recording unit 20. supply system. This configuration will be described with reference to FIG. 2 . the

As shown in FIG. 2 , each ink supplied from the ink tank 50 passes through the ink supply tube 44 and is supplied to the carriage 21 connected to the opposite end of the end provided with the connection terminal 43 , and then passes through the The flow path is supplied to the liquid jet head 22. At this time, in the present embodiment, each ink is supplied to the liquid ejection head 22 using the water level difference between the ink tank 50 and the liquid ejection head 22 . Then, each supplied ink is ejected from the liquid ejection head 22 toward the paper P when the carriage 21 moves, and an image or the like is printed on the paper P. the

That is, inside the device case 14 , the guide shaft 23 extending in the width direction (left-right direction) intersecting with the ejection direction of the paper P is erected.

Then, by moving the carriage 21 and moving the liquid ejecting head 22 , ink is ejected from the moving liquid ejecting head 22 to print (record) an image or the like on the paper P. FIG. In addition, in the present embodiment, the carriage 21 and the liquid jet head 22 correspond to the recording unit 20 . the

In addition, the printer 11 is provided with another ink supply system for supplying inks from the ink tanks to the recording unit 20 other than the ink supply system for supplying the respective inks from the ink tanks 50 to the recording unit 20 . That is, the printer 11 is provided with: a liquid container mounting portion 30 having a guide portion 31a and an ink cartridge holder (cartridge holder) 31; The flow path forming part 40 is a flow path through which each ink flows. By attaching the respective ink cartridges 55C, 55M, 55Y, and 55K (hereinafter collectively referred to as ink cartridges 55 ) to the ink cartridge holder 31, the respective inks accommodated in the ink cartridges 55 flow into the flow path forming portion 40 . Then, the ink flowing into the flow path forming portion 40 flows out from the opening 42 provided in the flow path forming portion 40 through the ink outflow mechanism provided in the flow path forming portion 40 . Accordingly, by supplying the respective inks flowing out from the opening 42 to the ink supply tube 44 , the respective inks can be supplied from the flow path forming portion 40 side to the recording portion 20 side. the

Therefore, in this embodiment, as shown in FIG. Ink is supplied to the side of the recording unit 20 . The connection port of the ink tank 50 to the ink supply tube 44 (connection terminal 43 ) is configured the same as the opening 42 that is the connection port to the ink supply tube 44 (connection terminal 43 ) of the channel forming part 40 . the

In addition, when one end (connection terminal 43 ) of the ink supply tube 44 is not connected to the flow path forming portion 40 , outflow prevention means is provided so that ink does not flow out from the opening 42 provided in the flow path forming portion 40 . That is, in the opening 42 , the ink flow path is closed by the capping member 45 as a closing member, and the flow by the outflow mechanism is blocked so that the ink does not flow out from the opening 42 . This outflow prevention unit, the outflow mechanism and ink flow paths provided in the flow path forming portion 40 will be described with reference to FIG. 3 . the

As shown in FIG. 3 , the front of the liquid storage body mounting portion 30 is open, and in the approximately box-shaped ink cartridge holder 31 having a space portion SP1 which functions as a mounting portion for mounting the holding body, there is an ink cartridge holder 31 provided in the space portion SP1. The rear supply needle 35 as a supply component. The supply needle 35 is guided from the bottom of the ink cartridge holder 31 by a guide portion 31a extending forward, and is inserted into an ink cartridge 55 (not shown in FIG. 2 ) slidably mounted from the front to the rear. Through this insertion, each ink flows from the ink cartridge 55 into the supply needle 35 in the liquid container mounting portion 30 . the

Each ink that has flowed into the supply needle 35 flows into the ink flow path provided in the flow path forming body 41 constituting the flow path forming portion 40 disposed behind the liquid container mounting portion 30 , that is, the flow path 41 a. The flow path 41 a is provided with an outflow mechanism for outflowing ink from the opening 42 . In the present embodiment, the outflow mechanism is constituted by a not-shown diaphragm pump and/or a check valve, etc., which fluctuate the pressure in the flow passage 41a. The pressure of the ink in the flow path 41 a is changed by driving the diaphragm pump from a driving source not shown. Each ink flows through the flow path 41 a through the pressure fluctuation and the check valve, and flows out from the opening 42 provided at the flow path end of the flow path 41 a in the flow path forming portion 40 . In addition, in the present embodiment, the opening portion 42 forms a connection port with the connection terminal 43 by a member having an opening serving as an ink flow path. the

Therefore, when the printer 11 is an ink supply system in which each ink flows and is supplied from the ink tank 50 side to the recording unit 20 side through the ink supply tube 44 connected to the ink tank 50 , in order not to flow out the ink from the opening 42 , the opening 42 is provided with an ink supply system. The cover member 45 is attached to the portion 42 to close the flow path end (opening) of the flow path 41a. Alternatively, of course, the opening 42 may be melted to close the flow path end (opening), or an adhesive may be poured in to close the flow path end (opening). the

The operation of the ink supply system having the ink tank 50 configured in this way will be described. As shown in FIG. 2 , the ink tank 50 is arranged outside the device main body 12 (device case 14 ), and thus forms a liquid storage body that stores a large volume of ink. In addition, ink is supplied to the recording section 20 by utilizing a water level difference without separately employing an outflow mechanism or the like. Even when the ink flows through the flow path forming portion 40 such as when the ink cartridge 55 is mounted, the opening 42 is closed, so that the ink flowing through the outflow mechanism in the flow path 41a can be prevented from flowing out of the opening 42 . the

However, in the printer 11, when ink is supplied from the ink cartridge 55, predetermined information data (such as identification of the ink cartridge and/or data on the remaining amount of ink, etc.) Communication. That is, in this embodiment, as shown in FIG. 3 , electrical terminals 32C, 32M, 32Y, and 32K serving as electrical contacts for performing information data communication with each ink cartridge 55 are provided on the upper portion of the ink cartridge holder 31 . After the ink cartridge 55 is installed, through each electrical terminal 56 (referring to Fig. 4) that this electrical terminal 32C, 32M, 32Y, 32K is correspondingly provided with, carry out the communication of predetermined information data between the memory element that each ink cartridge 55 possesses, and , to send message data to a control unit not shown in the figure. According to this communication, in the printer 11 , a control unit (not shown) performs recording processing on the paper P in the recording unit 20 or updates predetermined information data stored in the storage elements of the ink cartridges 55 . the

Therefore, the ink tank 50 is directly connected to the ink supply pipe 44, and when the ink is supplied from the ink tank 50, since there is no communication between the ink tank 50 and the electrical terminals 32C, 32M, 32Y, and 32K, the recording process of the recording unit 20 is not performed. Cases of non-execution. Alternatively, since the ink tank 50 contains more ink than the ink cartridge 55, for example, even if ink remains in the ink tank 50, the information data may become zero and the recording process may not be performed. the

Therefore, in the present embodiment, as shown in FIG. 3 , a dummy box 60 is installed in the liquid storage body mounting portion 30, and it communicates with the electrical terminals 32C, 32M, 32Y, and 32K, and corrects or resets predetermined information. data, the information data is updated so as to match the state of ink supply from the ink tank 50 . That is, the dummy cartridge 60 has a cartridge main body 61 as a holder that can be attached to the ink cartridge holder 31 instead of each ink cartridge 55 . In the box body 61 , the electrical terminals 62C, 62M, 62Y, and 62K held on the top surface can communicate data with the electrical terminals 32C, 32M, 32Y, and 32K in the mounted state. In this communicable state, for example, by operating the button 63 provided on the front surface of the cartridge body 61 , the information data is appropriately updated so as to match the state of ink supply from the ink tank 50 . As a result, in the printer 11, the recording process in the recording unit 20 is continued. In addition, a plurality of dummy cartridges 60 (here, four) may be prepared corresponding to the respective ink cartridges 55C, 55M, 55Y, and 55K, and each may be attached to the ink cartridge holder 31 . the

According to the above-described embodiment, the following effects can be obtained. the

(1) One end (connection terminal 43) of the ink supply tube 44 can be connected to the ink tank 50, therefore, it can be supplied from another liquid storage body different from the ink cartridge 55 mounted on the liquid storage body mounting part 30 without using an accessory. The recording unit 20 supplies ink. Therefore, the shape of the ink tank 50 is not limited to a shape that can be attached to the liquid storage body attachment portion 30, and may be formed in any shape. the

(2) The ink tank 50 may have a shape that stores a larger volume of ink than the ink tank 55 having a shape attached to the liquid container mounting portion 30 . the

(3) Ink can be supplied from the ink tank 50 to the recording unit 20 by using, for example, a water level difference without using a complicated pressurizing device. the

(4) Even if one end (connection terminal 43 ) of the ink supply tube 44 is removed from the flow path forming portion 40 (opening portion 42 ), ink does not flow out from the flow path forming portion 40 (opening portion 42 ). Therefore, by directly connecting one end (connection terminal 43 ) of the removed ink supply tube 44 to the ink tank 50 , ink can be supplied from the ink tank 50 to the recording unit 20 without an accessory. the

(5) In the flow path forming portion 40 , the outflow of ink from the flow path 41 a can be prevented by an easy method such as closing the opening portion 42 and/or stopping the operation of the flow mechanism. Therefore, when one end (connection terminal 43 ) of the ink supply tube 44 is not connected to the opening 42 of the flow path forming portion 40 , it is possible to easily suppress ink from flowing out of the opening 42 . the

In addition, the above-mentioned embodiment may be changed as follows. the

In the above embodiment, the connection side and the opposite side of the ink supply tube 44 of the connection terminal 43 preferably have the same structure as the attachment structure to the opening 42 formed on the cover member 45 . Alternatively, the opening 42 is preferably in a shape that is directly attached to the connection terminal 43 without passing through other components. This modified example will be described with reference to FIG. 4 . the

As shown in FIG. 4 , according to this modified example, the connection terminal 43 can be removed from the ink tank 50 and can be directly attached to the opening 42 where the cover member 45 is removed. In this way, for example, the ink cartridge 55C can be attached to the liquid container mounting part 30, the supply needle 35 can be inserted, and the cyan ink flowing out from the opening 42 can be supplied to the ink by the outflow mechanism after flowing in the flow path 41a of the flow path forming part 40. Tube 44C sends out. The same applies to other colored inks. the

As a result, for example, even if the ink in the ink tank 50 is consumed, ink can be supplied from the ink tank 55 to the recording unit 20 by merely changing the connection of the ink supply tube 44 from the ink tank 50 to the opening 42 . In addition, in order to consume the ink in the ink cartridge 55 , when switching the ink supply source to the ink tank 50 , the connection of the ink supply tube 44 may be changed from the opening 42 to the ink tank 50 . In addition, at the time of this change, the opening part 42 is attached and the cover member 45 is closed. In this way, according to this modified example, it is possible to easily change between the ink supply system from the ink tank 50 and the ink supply system from the ink cartridge 55 . the

- In the above embodiment, when one end (connection terminal 43 ) of the ink supply tube 44 is not connected to the opening 42 of the flow path forming part 40 , it is not necessary to suppress the outflow of ink from the opening 42 by the outflow preventing means. For example, when the printer 11 is used for the first time and the ink cartridge 55 has not been installed in the past, there is no ink in the flow path forming portion 40, or there is no sufficient amount of liquid in the flow path 41a to flow out. In such a case, the ink does not flow out from the opening 42 , and thus no outflow preventing means is required. the

- In the above-described embodiment, the ink tank 50 may supply ink by a method other than the water level difference. For example, a method of pressurizing the inside of the ink tank 50 with air pressure by a pressurizing unit to pressurize the ink and supply it to the ink supply tube 44 may be employed. the

- In the above embodiment, the arrangement position of the ink tank 50 is not necessarily limited to the outside of the device casing 14 . For example, the ink tank 50 may be formed in the device case 14 or at least a part of the device case 14 may be formed. the

- In the above embodiment, if one end (connection terminal 43 ) of the ink supply tube 44 is not connected to the flow path forming portion 40 (flow path 41 a ), this end does not need to be connected to the ink tank 50 . For example, at the time of maintenance such as replacing the ink supply tube 44, even if the connection terminal 43 is removed from the opening 42 of the flow path forming part 40 to form a state where one end of the ink supply tube 44 is not connected to the flow path 41a, it is possible to suppress the flow from the ink supply tube 44. Ink flows out from the opening portion 42, so maintenance operations become easy. the

- In the above-described embodiment, the outflow preventing means for preventing the ink from flowing out from the opening 42 may be realized by a method other than closing the opening 42 . For example, the outflow of ink may be prevented by stopping the ink pressure fluctuation operation and stopping the outflow mechanism. Specifically, by stopping the driving source (for example, a decompression pump) for operating the diaphragm pump, the operation of the diaphragm pump can be stopped without changing the ink pressure. As a result, in the flow path forming portion 40 , the ink pressure fluctuation operation in the outflow mechanism can be stopped by an easy method of stopping the operation of the diaphragm pump, thereby preventing the ink from flowing out from the opening 42 . In addition, it is of course also possible to configure the outflow prevention means by a combination method of closing the opening 42 and stopping the ink pressure fluctuation operation. the

- In the above-mentioned embodiments, the recording medium is not limited to the paper P, and may be a plate-shaped member made of a metal plate, a resin plate, cloth, or the like. That is, as long as the ink can be transported and consumed by the recording unit 20 and can be recorded, any member can be used as the recording medium. the

- In the above embodiment, the recording unit 20 is not limited to a serial printer in which the liquid ejection head 22 reciprocates along with the carriage 21, and may be a line that can print on the widest range of paper with the liquid ejection head 22 fixed. type printer. the

· In the above embodiment, the printer 11 may be a device without the scanner unit 13 , or may be a multifunction peripheral having functions such as a FAX device and/or a copying device together with the recording unit 20 . the

- In the above-described embodiment, the printing device is embodied as the inkjet printer 11 including the liquid ejection head that ejects ink, but a liquid ejection device that ejects liquid other than ink may also be used. It can be used in various liquid ejection devices including a liquid ejection head that ejects a small amount of liquid droplets. In addition, the liquid drop means the state of the liquid ejected from the above-mentioned liquid ejecting device, and includes granular, tear-like, and thread-like trailing shapes. In addition, the liquid here may be any material that can be ejected by a liquid ejecting device. For example, as long as the substance is in the liquid phase, such as high or low viscosity liquid, sol, gel water, other inorganic solvents, organic solvents, solutions, liquid resin, liquid metal (melt metal) Fluids are not only liquids in one state of matter, but also include particles of functional materials composed of solids such as pigments, metal particles, etc. dissolved, dispersed, or mixed in a solvent. In addition, as a representative example of the liquid, there are ink, liquid crystal, and the like described in the above embodiment. Here, the ink includes general water-based inks and oil-based inks, as well as various liquid compositions such as neutral inks and hot-melt inks. As a specific example of a liquid ejecting device, for example, a liquid that sprays and disperses or dissolves materials such as electrode materials and color materials used in the manufacture of liquid crystal displays, EL (electroluminescence) displays, surface emission displays, and color filters liquid injection device.
