The upper guide rail 5 is arranged along the X direction, and a predetermined portion of the recording carriage unit 20 can be engaged with the upper guide rail 5 to guide the movement of the recording carriage unit 20 in the X direction. The moving unit 30 records by driving the motor M in a state where a predetermined portion of the recording carriage unit 20 is engaged with the upper guide rail 5 and the lower guide rail 12e and movement in the Y direction and the Z direction is restricted. The carriage unit 20 is reciprocated within a predetermined range along the X direction.

[Recording carriage unit]
Next, the details of the recording carriage unit 20 will be described with reference to FIGS. 3, 4 (a) and 4 (b). The recording carriage unit 20 has a main carriage 21 as a main moving portion, a sub-carriage 22 as a holding portion, a recording head H, a slide member 23 as an auxiliary moving means, and a carriage spring 25 (see FIG. 4).

The main carriage 21 reciprocates in the X direction. Specifically, the main carriage 21 is restricted from moving in the Y direction and the Z direction because a predetermined portion engages with the upper guide rail 5 and the lower guide rail 12e. Further, the main carriage 21 is capable of reciprocating (reciprocating scanning) in the X direction together with the subcarriage 22 and the recording head H along the upper guide rail 5 and the lower guide rail 12e by driving the motor M (see FIG. 2). ). Further, the main carriage 21 holds the sub-carriage 22 so as to be movable in the Y direction with respect to the main carriage 21, and holds the slide member 23 so as to be movable in the X direction with respect to the main carriage 21.

The subcarriage 22 holds the recording head H detachably. For example, the sub-carriage 22 has a side wall (not shown), a rear regulating portion (not shown), a recording head support portion (not shown), and an engaging portion (not shown) that regulate the movement of the recording head H with respect to the sub-carriage 22. have. The side walls are arranged in pairs at a distance corresponding to the width of the recording head H in the X direction and separated in the X direction, and restrict the movement of the recording head H with respect to the subcarriage 22 in the X direction. When the recording head H is attached from the front side (Y2 side), the rear regulating portion can abut in the Y direction with respect to a predetermined portion of the recording head H, and by abutting with the recording head H, the rear regulating portion of the recording head H Restricts backward movement (Y1 direction) with respect to the subcarriage 22.

Further, for example, the recording head support portion is arranged on the rear end side (Y1 side) of the recording head H and is formed so as to project in the X direction from the side surface of the recording head H in the X direction (not shown). It is possible to contact the lower side (Z2 side) of the recording head H and support the recording head H from below.

The recording head H is supported so that the Y2 side) can swing in the Z direction. The engaging portion can engage with the engaged portion (not shown) formed on the recording head H with the recording head H attached to the subcarriage 22, and engages with the engaged portion. This regulates the swing of the recording head H on the front end side (Y2 side) in the Z direction.

For example, when the recording head H is attached to the sub-carriage 22, the user first tilts the recording head H backward (in the Z2 direction) so that the front end side (Y2 side) of the recording head H is slightly downward (Z2 direction) with respect to the sub-carriage 22. By moving in the Y1 direction), the recording head H is inserted between the pair of side walls and abutted against the rear restricting portion. Next, the user supports the rear end side of the recording head H by the recording head support portion in a state where the recording head H is abutted against the rear regulating portion and the protruding portion of the recording head H is brought into contact with the recording head support portion. In this state, the front end side (Y2 side) of the recording head H is moved upward (Z1 direction) to engage the engaged portion with the engaged portion. In this way, the recording head H is attached to the sub-carriage 22 and is restricted from moving in the X-direction, Y-direction, and Z-direction with respect to the sub-carriage 22. Further, for example, when the user removes the recording head H from the subcarriage 22, the procedure is opposite to the procedure for mounting the recording head H, that is, the front end side (Y2 side) of the recording head H is downward (Z2 direction, and the base plate). The recording head H is removed by moving the recording head H in the direction approaching 12), disengaging the engaged portion from the engaged portion, and moving the recording head H forward (in the Y2 direction).

The subcarriage 22 has a substrate (not shown) that electrically connects the contact point of the recording head H and the control unit 50 in a state where the recording head H is held (attached). From the recording head H, a signal according to whether or not the recording head H is attached, a signal according to the remaining amount of ink, and a signal corresponding to the position of the recording head H by the linear encoder 33 via the substrate of the subcarriage 22. Etc. are output to the control unit 50. A control signal for controlling the recording head H is output from the control unit 50 to the recording head H via the substrate of the subcarriage 22. Further, the sub-carriage 22 is formed so as to project rearward (in the Y1 direction) at the rear end portion of the sub-carriage 22, and has an abutting portion 22a that can slide while abutting on the slide member 23.

The recording head H has a ejection portion Ha arranged at a lower portion and a plurality of ejection ports (nozzles, not shown) for ejecting ink, an ink cartridge for storing ink (not shown), and the like, and is a subcarriage 22. It is a detachable unit. The recording head H can eject ink from the ejection unit Ha to form (record) an image having a predetermined length in the Y direction on the recording medium P. In the present embodiment, the recording head H can form an image whose Y direction is 0.5 inch.

The ink cartridge and the recording head H may be integrated or separate. When the ink cartridge and the recording head H are separate bodies, it is possible to remove and replace only the ink cartridge.

The slide member 23 is provided between the rear contact surface 22b, which is the rear surface of the contact portion 22a of the sub-carriage 22, and the facing surface 21a of the main carriage 21 facing the rear contact surface 22b in the Y direction. It is held so as to be movable in the X direction. In the present embodiment, the slide member 23 is inserted between the rear contact surface 22b of the sub-carriage 22 and the facing surface 21a of the main carriage 21 through a through hole (not shown) formed in the main carriage 21. .. Further, the slide member 23 is formed longer in the X direction than the main carriage 21. Therefore, depending on the position of the slide member 23 in the X direction with respect to the main carriage 21, either one or both of the right end (X1 direction end) and the left end (X2 direction end) of the slide member 23 are main. It protrudes from the carriage 21 in the X direction.

The slide member 23 is configured so that the thickness in the Y direction is different in at least two steps at different positions in the X direction. In the present embodiment, the slide member 23 is formed so that the surfaces of the portions having different thicknesses are connected by the inclined surface. Specifically, the slide member 23 is formed so that the rear surface 23a (one surface) in the Y direction facing the facing surface 21a of the main carriage 21 is parallel to the X direction over the entire X direction. .. Further, in the slide member 23, of the front surface 23b (other surface) in the Y direction facing the rear contact surface 22b of the subcarriage 22, the left regulation surface 23d on the X2 side of the right regulation surface 23c on the X1 side is in the Y2 direction. It is formed so as to protrude from the carriage. The right regulation surface 23c and the left regulation surface 23d are formed so as to be parallel to the rear surface 23a, and are smoothly connected by the inclined surface 23e. In the present embodiment, the slide member 23 has a larger thickness in the Y direction on the X2 side than on the X1 side.

The carriage spring 25 is hung on a part of the main carriage 21 and a part of the sub-carriage 22, and urges the sub-carriage 22 toward the rear (Y1 direction) in the Y direction with respect to the main carriage 21. ing. The carriage spring 25 urges the sub-carriage 22 toward the rear (Y1 direction) with respect to the main carriage 21 to sandwich the slide member 23 between the main carriage 21 and the sub-carriage 22. By the carriage spring 25, the rear surface 23a of the slide member 23 abuts on the facing surface 21a of the main carriage 21, and the rear contact surface 22b of the subcarriage 22 abuts on the front surface 23b of the slide member 23.

The position of the recording head H (sub-carriage 22) with respect to the main carriage 21 in the Y direction is determined by the position of the slide member 23 with respect to the main carriage 21 in the X direction. Specifically, when the portion of the slide member 23 having a large thickness in the Y direction is located between the facing surface 21a of the main carriage 21 and the rear contact surface 22b of the subcarriage 22, the recording head H is the main carriage. It is located at the rear position (first position) on the Y1 side with respect to 21. On the other hand, when the portion of the slide member 23 having a small thickness in the Y direction is located between the facing surface 21a and the rear contact surface 22b, the recording head H is on the Y2 side of the main carriage 21 with respect to the rear position. It is located in the front position (second position), which is the position. In this way, the slide member 23 moves relative to the main carriage 21 in the X direction, so that the recording head H moves in the Y direction with respect to the main carriage 21 together with the sub-carriage 22.

[Relationship between the X-direction position and the Y-direction position of the recording head]
Next, the relationship between the position of the recording head H in the X direction and the position in the Y direction will be described with reference to FIGS. 4 and 5. In the present embodiment, as the recording carriage unit 20 moves in the X direction, the end portion of the slide member 23 in the X direction comes into contact with a part of the base 18, and the slide member 23 moves in the X direction with respect to the main carriage 21. It is configured to move to.

Specifically, as shown in FIG. 4A, when the main carriage 21 is located at the right end (end in the X1 direction) of the moving region that can move in the X direction, the right end of the slide member 23 (End portion in the X1 direction) abuts on the right contact plate 7 provided on the base 18. In this state, the portion of the slide member 23 having a small thickness in the Y direction is located between the facing surface 21a of the main carriage 21 and the rear contact surface 22b of the subcarriage 22, and the subcarriage 22 is located in the Y direction. It is located behind. When the 1 main carriage 21 moves to the left (X2 direction) in this state, the recording head H remains held by the sub-carriage 22 located at the rear position as shown in FIG. 5 (b). It moves (main scan) along the X direction toward the left end (end in the X2 direction) of the movement area.

Further, as shown in FIG. 4B, when the recording head H is located at the left end (X2 direction end) of the moving region, the left end (X2 direction end) of the slide member 23 is the base 18. It comes into contact with the left contact plate 6 provided in.

It is located in front of. When the recording carriage unit 20 moves to the right (X1 direction) in this state, the recording head H remains held by the subcarriage 22 located at the front position as shown in FIG. 5A. It moves in the X1 direction toward the right end (end in the X1 direction) of the movement area.

The positional relationship between the inkjet recording apparatus 100 and the recording head H will be described with respect to the state of FIG. 4A, that is, the case where the subcarriage is in the rear position, and the state of FIG. 4B, that is, the case where the subcarriage is in the front position. do. Of the plurality of discharge ports Ha1 provided in the discharge portion Ha, the shortest distance in the Y direction (the shortest distance) from the rear regulation surface 12b in FIG. 3 is located at the end in the Y1 direction. It is a discharge port Ha2. Then, when comparing the distance in the Y direction between the discharge port Ha2 and the rear regulation surface 12b, the distance when the sub-carriage is in the front position is longer than the distance when the sub-carriage is in the rear position.

Further, the recording carriage unit 20 moves to the right (X1 direction) while the recording head H is held in the state of FIG. 5A, that is, the subcarriage 22 located at the front position, and the recording head H moves. When the slide member 23 reaches a predetermined position on the right side (X1 side) of the recording area opening 12c, the right end (X1 direction end) of the slide member 23 comes into contact with the right contact plate 7. Further, when the recording carriage unit 20 moves to the right (X1 direction), the slide member 23 is pressed by the right contact plate 7 and moves to the left (X2 direction) with respect to the main carriage 21 to move to the left (X2 direction), and the sub-carriage The movement toward the rear position of 22 is started. Further, when the recording carriage unit 20 moves to the right (X1 direction), the slide member 23 is in contact with the cleaning blade 42 whose position in the X direction of the discharge portion Ha of the recording head H held by the subcarriage 22 is described later. The movement of the sub-carriage 22 to the rear position is completed by the time the contact position is reached.

Further, the recording carriage unit 20 moves to the left (X2 direction) in the state of FIG. 5B, that is, in the state where the subcarriage 22 is located at the rear position, and the recording head H held by the subcarriage 22 When the slide member 23 reaches a predetermined position on the left side (X2 side) of the recording area opening 12c, the left end (X2 direction end) of the slide member 23 comes into contact with the left contact plate 6. Further, when the recording carriage unit 20 moves to the left (X2 direction), the slide member 23 is pressed by the left contact plate 6 and moves to the right (X1 direction) with respect to the main carriage 21 to move to the sub-carriage. The movement of the 22 to the front side (Y2 side) is started. Further, when the recording carriage unit 20 moves to the left (X2 direction), the slide member 23 has a left end portion (X2 direction end portion) of the movement region in which the position of the recording head H is in the X direction, that is, a replacement described later. By the time the position is reached, the sub-carriage 22 finishes moving to the front side (Y2 side).

In this way, when the sub-carriage 22 reciprocates in the X direction, it moves forward (Y2 direction) or backward (Y1 direction) by the slide member 23. In this way, the slide member 23 moves the sub-carriage 22 to the front side (Y2) in conjunction with the operation of the sub-carriage 22 moving to the left end (X2 side) of the movement range (predetermined range) by the moving unit 30. The sub-carriage 22 is moved to the front position on the side), and the sub-carriage 22 is moved to the rear of the rear side (Y1 side) in conjunction with the operation of moving the sub-carriage 22 to the right end (X1 side) of the movement range by the moving unit 30.

Ink is ejected to the medium P, and the second half of the outward route is recorded on the recording medium P as shown in FIG. 6A. After that, the recording head H moves to the front position together with the sub-carriage 22 at a position deviating from the predetermined recording area, and moves to the right (X1 direction) as shown in FIG. 5A while moving to the recording area. Ink is ejected to the recording medium P through the opening 12c, and the first half of the return path is recorded on the recording medium P as shown in FIG. 6 (b). In this way, the recording head H records in a predetermined recording area of the recording medium P with a width twice the width in the Y direction in which the recording head H can record. In the present embodiment, the recording head H records 0.5 inch wide for outbound recording and return recording, and 1 inch wide recording is performed on the recording medium P.

[Cleaning unit]
Next, the cleaning unit 40 for cleaning the recording head H will be described with reference to FIGS. 7 and 8. As shown in FIGS. 7A and 7B, the cleaning unit 40 includes a base member 41, a cleaning blade 42 as a cleaning member, a blade elevating mechanism 43, a cap 45 as a covering member capable of covering the discharge portion Ha, and a cap. It has an elevating mechanism 46 and a suction unit 60 as a suction means. The base member 41 supports the cleaning blade 42 and the cap 45 so as to be able to move up and down.

The blade elevating mechanism 43 as a cleaning member moving means has a contact position where the cleaning blade 42 can abut on the discharge portion Ha and a retracted position where the cleaning blade 42 is retracted from the contact position as the recording head H moves in the X direction. Move (elevate) between. For example, the blade elevating mechanism 43 holds the recording head H at the contact position when approaching the cleaning blade 42 from the left side (X2 side), and when the recording head H approaches from the right side (X1 side). The cleaning blade 42 is moved so as to hold it in the retracted position.

When the recording head H is positioned in the front position in the space T1 on the right side (X1 side) of the right regulation surface 12a and on the front side (Y2 side) of the rear regulation surface 12b of the cleaning blade 42. It is arranged on the rear side (Y1 side) of the end portion on the front side (Y2 side) of the discharge portion Ha (the end portion of the region where the plurality of discharge ports Ha1 are arranged, see FIG. 4B).

The cleaning blade 42 abuts (slides) on the ejection portion Ha of the recording head H which is moved in the X direction by the moving unit 30 in a state where the cleaning blade 42 is located at the abutting position, so that the ink adhered to the ejection portion Ha after recording. Wipe off and clean the discharge part Ha. Since the cleaning blade 42 is arranged at a position on the right side (X1 side) of the right regulation surface 12a, which is a position deviating from the position where the recording medium is positioned by the positioning unit R, the cleaning blade 42 is arranged at a position on the right side (X1 side) of the right regulation surface 12a. It is possible to prevent the scattered ink from adhering to the recording medium.

Further, when the recording head H approaches the cleaning blade 42 from the left side (X2 side), it is often after recording on the recording medium, and it is very important to clean the discharge portion Ha by the cleaning blade 42. When the recording head H approaches the cleaning blade 42 from the right side (X1 side), since the recording to the recording medium has not been performed since the discharge portion Ha was cleaned last time, the discharge portion is used by the cleaning blade 42. The importance of cleaning Ha is low.

As described above, the blade elevating mechanism 43 is highly important for cleaning the discharge portion Ha, and is cleaned when the recording head H passes the cleaning blade 42 from the right side (X1 side) to the left side (X2 side). The blade 42 is held in the contact position. As a result, the frequency with which the cleaning blade 42 comes into contact with the discharge portion Ha is reduced, and deterioration of the portion where the cleaning blade 42 and the discharge portion Ha come into contact with each other is suppressed.

The cap elevating mechanism 46 as a covering member moving means has a covering position shown in FIG. 8 (b) in which the cap 45 can cover the discharge portion Ha, and is retracted downward from the covering position to allow the recording head H to move. It is moved (elevated) between the uncovered position shown in 8 (a) and the uncovered position. The cap 45 is arranged on the front side (Y2 side) of the rear regulation surface 12b and on the right side (X1 side) of the cleaning blade 42. Further, the cap 45 is in the X direction and the Y direction with respect to the discharge portion Ha in the state where the recording head H is located at the rear position and at the end portion (home position described later) on the right side (X1 side) of the moving range. It is formed large and can cover the discharge portion Ha in the state where the recording head H is located at the home position. The cap 45 is connected to a suction unit 60 capable of sucking air.

The suction unit 60 has a pump 61 operated by a motor PM (see FIG. 8C), and a pipe 62 connecting the pump 61 and the cap 45. The cap 45 is formed with a suction port 47 as a suction portion that is connected to the pipe 62 and opens upward. The suction port 47 is arranged on the rear side (Y1 side) of the discharge port Ha2 (see FIG. 4) located at the end of the discharge portion Ha on the rear side (Y1 side) when the recording head H is located in the front position.

The suction port 47 sucks the ink adhering to the ejection portion Ha by sucking air with a negative pressure in a state where the ejection portion Ha is covered by the cap 45 located at the covering position, and the ejection portion Ha is sucked. To clean.

After the ink is wiped off by the cleaning blade 42, the ejection portion Ha is covered with the cap 45 to suppress the drying of the ink, and the ink is sucked by the suction unit 60 to eject the ejection portion Ha due to the sticking of the ink. Clogged outlets are suppressed. As a result, the ejection portion Ha is maintained in a good state in which ink can be ejected. The cleaning blade 42 and the suction port 47 described above constitute a cleaning unit C as a cleaning means for cleaning the discharge unit Ha (discharge port) of the recording head H.

[Control unit]
FIG. 8C is a block diagram showing a control configuration of the inkjet recording apparatus 100 of the present embodiment. The control unit 50 has a CPU, RAM, and ROM (not shown). The CPU controls each part while reading a program corresponding to the control procedure stored in the ROM. Further, work data and input data are stored in the RAM, and the CPU controls by referring to the data stored in the RAM based on the above-mentioned program or the like. The control unit 50 controls each motor and the recording head H based on input signals from each sensor, switch, and the like.

For example, when the control unit 50 detects that the recording medium P is positioned on the positioning unit R based on an input signal or the like from the detection sensor 16, the lifter 13 is raised and the recording medium P is moved to the base plate 12. Press on. Further, for example, the control unit 50 receives an input signal from the position detector E that outputs a signal according to the amount of movement of the recording carriage unit 20 in the X direction in a state where the recording medium P is positioned on the positioning unit R. Based on this, the drive of the moving unit 30 (motor M) and the ejection of ink from the recording head H are controlled.

In the present embodiment, the control unit 50 controls the position of the recording carriage unit 20 in the X direction by the DC motor, the linear encoder 33, and the position detector E, but the present invention is not limited to this. The control unit may control the position of the recording carriage unit 20 in the X direction by a DC motor, a rotary encoder, a DC motor, a plurality of optical sensors arranged in the X direction, a stepping motor, or the like. Further, the control unit 50 can execute a head exchange mode for the user to exchange the recording head H, as will be described in detail later.

[Recording head home position and replacement position]
Next, the home position as the standby position of the recording head H and the exchange position as the attachment / detachment position will be described with reference to FIGS. 1 to 3 and 5. A home position and an exchange position are provided as positions of the recording head H in the moving regions in the X direction and the Y direction in which the recording head H can move. The home position of the recording head H (sub-carriage 22) is a standby position when the power of the inkjet recording device 100 is on and the inkjet recording device 100 is in the standby state, and waits for recording on the next recording medium. This is the position of the recording head H (subcarriage 22) which is the starting point for starting the movement when recording on the recording medium.

Specifically, the home position of the recording head H is the position of the recording head H in the X and Y directions shown in FIG. 3, and is the right end (X1 side) end and rearward in the moving region of the recording head H. It is provided at the position. As described above, when the recording head H moves to the right (X1 direction), it starts moving backward (Y1 direction) at a position on the right side (X1 side) of the recording area opening 12c. .. Therefore, in the home position, the recording head H is located on the right side (X1 side) of the recording area opening 12c. The home position of the main carriage 21 is a position where the recording head H is located at the home position. In other words, the recording area is located between the positions of the plurality of ejection ports when the main carriage 21 is in the home position and the positions of the plurality of ejection ports when the main carriage 21 is in the replacement position. In other words, when the main carriage 21 is in either the home position or the exchange position, the discharge port of the recording head H is located outside the recording area.

When the control unit 50 records the return path by the recording head H and the recording on the recording medium is completed, the control unit 50 moves the recording head H to the right side (X1) of the moving range in order to move the recording head H to the rear position. The moving unit 30 is controlled so as to be moved to the end of the side). In this embodiment, it is moved to the home position after the recording is completed. When the recording head H reaches the cleaning blade 42, the ink adhering to the ejection portion Ha is wiped off by the cleaning blade 42. After the ink in the ejection portion Ha is wiped off, the recording head H is further moved to the right (X1 direction) by the moving unit 30 to reach the home position. When the recording head H reaches the home position, it stops moving and waits for recording on the next recording medium. The ejection portion Ha is covered with the cap 45 in a state where the recording head H is located at the home position, and the ink of the ejection portion Ha is sucked by the suction unit 60.

The replacement position of the recording head H (sub-carriage 22) is the position of the recording head H (sub-carriage 22) when the user replaces the recording head H. Specifically, the replacement position of the recording head H is the position of the recording head H shown in FIGS. 1 and 2, and is the end portion on the left side (X2 side) in the X direction in the moving region of the recording head H. It is provided at the front position (the position on the Y2 side of the home position). As described above, when the recording head H moves toward the left (X2 direction), it starts moving forward (Y2 direction) at a position on the left side (X2 side) of the recording area opening 12c. .. Therefore, in the exchange position, the recording head H is located on the left side (X2 side) of the recording area opening 12c. When the head replacement mode described later is started by the control unit 50, the recording head H is driven by the motor M and moves to the left (X2 direction) and forward (Y2 direction) to reach the replacement position. The recording head H stops moving when it reaches the home position.

In the base plate 12, a notch portion 12d as a non-interference portion formed in a notch shape is formed below the recording head H located at the exchange position. The cutout portion 12d has a range in which contact between the recording head H and the base plate 12 can be avoided when the front end side of the recording head H is moved up and down in the replacement position, and the strength of the base plate 12 around the recording area opening 12c is increased. It is formed to the extent that it is not impaired. For example, the notch portion 12d cuts out the base plate 12 on the right side (X1 side) of the notch portion 12d and on the rear side (Y1 side) of the end edge 12g on the front side (Y2 side) of the base plate 12. , It is formed so as to be discontinuous with the recording area opening 12c.

Further, for example, the notch portion 12d downwards (Z2 direction) with the recording head H in front of the recording head H (Y2 side) in the exchange position while the recording head H is in contact with the rear regulating portion of the subcarriage 22. When moved, at least the opening of the discharge port is cut out so as not to contact the base plate 12. The non-interfering portion is not limited to the one having a notch shape, and may be formed so as to be recessed downward (Z2 direction).

The recording head H can be attached and detached. Further, the cover body 3 is provided with an open / close sensor 8 (see FIG. 1) capable of detecting the open state and the closed state of the open / close door 9. The open / close sensor 8 outputs a signal corresponding to the open / closed state of the open / close door 9 to the control unit 50.

In the case of the present embodiment as described above, since the recording head H can be attached and detached at the exchange position where the sub-carriage 22 is located in the front position, the operator can easily access the recording head H and the recording head. The holding portion of H can be easily seen from the front side (Y2 side), and workability during maintenance such as attaching / detaching the recording head H can be improved. Further, in the inkjet recording device 100 of the present embodiment, since the recording head H can be attached to and detached from the opening 3b at the exchange position where the subcarriage 22 is located at the front position, the recording head H can be attached to and detached from the opening 3b. The distance in the Y direction is small, and workability when attaching and detaching the recording head H can be improved. In particular, when the inkjet recording device 100 has a structure in which the opening / closing door 9 cannot be opened greatly, the effect of improving workability is great.

[Head replacement mode]
Next, the head exchange mode executed by the control unit 50 based on a predetermined input signal will be described with reference to FIGS. 1, 3 and 9. For example, when a signal indicating that the remaining amount of ink in the ink cartridge is low or the ink is exhausted is input from the recording head H to the control unit 50, the control unit 50 tells the user that the ink cartridge is low. Notifying that the remaining amount of ink is low or that the ink is exhausted (recording head replacement request) is performed (S1). For example, a lamp provided at a predetermined position of the device is turned on. Then, when the user operates the recording head replacement start button of the device or touches the icon of the liquid crystal panel (when an instruction is input) in order to replace the recording head H, the control unit 50 (S2). ), The head exchange mode for exchanging the recording head H is started.

The recording head replacement request requesting the user to replace the recording head H may be displayed on a liquid crystal display such as a PC provided in or connected to the device, or an error message may be displayed by a speaker. The voice or error sound may be emitted. Further, the control unit 50 may, for example, have a signal indicating that the total usage time of the recording head has reached a predetermined time, a signal indicating that the amount of recording performed has reached a predetermined amount, and a recording head other than the remaining amount of ink. A recording head replacement request may be output in response to a signal or the like indicating an abnormality in.
