Further, the Y direction is an example of the device depth direction that intersects both the A direction and the B direction, which will be described later. The + Y direction is the direction toward the front of the Y direction, and the −Y direction is the direction toward the back of the Y direction.
The X direction is the device width direction and is the horizontal direction. The + X direction is the direction toward the left in the X direction when viewed from the operator of the printer 1, and the −X direction is the direction toward the right in the X direction.
The Z direction is the device height direction.

In the printer 1, the medium P is conveyed through the transport path T indicated by the broken line.
The AB coordinate system shown on the XX plane is a Cartesian coordinate system. The A direction is an example of the transport direction of the medium P in the region of the transport path T facing the line head 20, which will be described later. The direction toward the upstream in the A direction is referred to as the −A direction, and the direction toward the downstream is referred to as the + A direction. In the present embodiment, the A direction is a direction inclined so that the + A direction side is located on the + Z direction side with respect to the −A direction side. The B direction is an example of a moving direction, and is a moving direction in which the line head 20 described later moves forward and backward with respect to the transport unit 10 described later. The direction in which the line head 20 approaches the transport path T in the B direction is referred to as the + B direction, and the direction away from the transport path T is referred to as the −B direction. In the present embodiment, the B direction is a direction inclined so that the + B direction side is located on the + Z direction side with respect to the −B direction side, and is orthogonal to the A direction.

Specifically, as shown in FIG. 2, when the angle formed by the B direction and the X direction is the first angle θ1 when viewed from the Y direction, the first angle θ1 is 45 degrees, which is larger than 0 degrees. Same or smaller, specifically greater than 10 degrees and equal to or less than 40 degrees, more specifically 30 degrees. Further, when the angle formed by the A direction and the X direction is the third angle θ3, the third angle θ3 is the same as or larger than 45 degrees and smaller than 90 degrees, specifically, larger than 50 degrees and the same as 80 degrees. Or smaller, more specifically 60 degrees. As described above, the moving direction in which the line head 20 advances and retreats with respect to the transport unit 10 described later is an inclined direction intersecting both the horizontal direction and the vertical direction. Further, the transport direction of the medium P in the region including the transport unit 10 in which recording is performed by the line head 20 is an inclined direction intersecting both the horizontal direction and the vertical direction.

As shown in FIG. 1, the printer 1 has a housing 2 as an example of a device main body. It is assumed that the housing 2 is placed on a horizontal plane. In the + Z direction from the center of the housing 2 in the Z direction, a discharge portion 3 is formed to form a space portion in which the medium P on which information is recorded is discharged. Further, a plurality of medium cassettes 4 are provided in the −Z direction from the center of the Z-direction of the housing 2. The medium cassette 4 is an example of a medium accommodating unit. Further, in the center of the housing 2 in the Z direction, a manual feed tray 9 is provided so as to project from the housing 2 in the −X direction. In other words, the manual feed tray 9 is provided on the −X direction side with respect to the transport path T. The manual tray 9 in which the medium P can be set is used when recording on the medium P which cannot be set in the medium cassette 4.

A plurality of media P are stacked and housed in the plurality of medium cassettes 4. A pick roller 6 is provided so as to be in contact with the upper surface of the medium P in the direction of −X from the center of the medium cassette 4. The pick roller 6 is located below the discharge unit 3. The medium P housed in each medium cassette 4 is sent out from the medium cassette 4 toward the transport path T in the −X direction by the pick roller 6. The medium P sent out by the pick roller 6 toward the transfer path T is conveyed along the transfer path T by the transfer roller pair 7 and the transfer roller pair 8. The transport path T is provided with a transport path T1 in which the medium P is transported from an external device, and a transport path T2 that joins the transport path T from the −X direction side. The transport path T2 can transport the medium P set in the manual feed tray 9 to the transport path T. The manual tray 9 is located on the −X direction side with respect to the position where the transport path T2 merges with the transport path T. According to this, it is easy to form the transport path T2 along the manual feed tray 9 with less curvature.

Further, in the transport path T, a transport unit 10 described later, a plurality of transport roller pairs 11 for transporting the medium P, a resist roller pair 11A for correcting the inclination of the medium P, a discharge roller pair 11B, and a medium P are included. A plurality of flaps 12 for switching the conveyed route and a medium width sensor 13 for detecting the width of the medium P in the Y direction are arranged.

The transport path T is curved in a region facing the medium width sensor 13, and extends diagonally upward from the medium width sensor 13, that is, in the + A direction. A resist roller pair 11A is provided upstream of the transport unit 10 in the transport path T. The resist roller pair 11A is arranged on the −A direction side with respect to the transport unit 10. The resist roller pair 11A corrects the skew of the conveyed medium P. The skew of the medium P means a state in which the posture of the medium P is tilted with respect to the transport direction.

Downstream of the transport unit 10 in the transport path T, a transport path T3 and a transport path T4 toward the discharge unit 3 and an inversion path T5 for inverting the front and back of the medium P are provided. In the transport path T3 and the transport path T4, a discharge roller pair 11B for discharging the medium P on which ink is discharged toward the discharge unit 3 is arranged. The discharge roller pair 11B is provided at a position on the −X direction side with respect to the discharge unit 3. The discharge roller pair 11B discharges the medium P in the + X direction. The medium P on which the ink is discharged is discharged to the discharge unit 3 and laminated.

Further, in the housing 2, an ink accommodating unit 23 for accommodating ink, a waste liquid storage unit 16 capable of storing ink waste liquid, and a control unit 26 for controlling the operation of each unit of the printer 1 are provided. There is. The ink accommodating portion 23 supplies ink to the line head 20 via a tube (not shown). As shown in FIG. 2, the waste liquid storage unit 16 is connected to the first maintenance unit 62, which will be described later, via a flexible waste liquid tube 16A. The waste liquid storage unit 16 is located below the first maintenance unit 62. The waste liquid storage unit 16 collects maintenance ink discharged from the line head 20 toward the first maintenance unit 62, which will be described later, via the waste liquid tube 16A and stores it as waste liquid.

The control unit 26 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a storage (not shown), and is configured by transporting a medium P in the printer 1 and by using a line head 20. The operation of recording information on the medium P is controlled.

As shown in FIG. 2, the discharge unit 3 is provided with a discharge tray 21 in line with the transport path T3 and the transport path T4. The discharge tray 21 forming the bottom of the discharge unit 3 is a plate-shaped member as an example of the mounting member, and has a mounting surface 21A on which the discharged medium P is placed. Further, the discharge tray 21 is provided downstream of the transport unit 10 described later in the transport path T of the medium P and in the Z direction in the + Z direction with respect to the line head 20 described later.

Specifically, the discharge tray 21 extends in an oblique direction so that the portion on the + X direction side is located in the + Z direction with respect to the portion on the −X direction side. In other words, in the transport direction of the medium P, the downstream end portion of the discharge tray 21 is located in the + Z direction with respect to the upstream end portion. The mounting surface 21A has an inclination toward diagonally upward along the discharge direction of the medium P.

In FIG. 2, the angle formed by the inclination direction of the mounting surface 21A and the X direction when viewed from the Y direction is defined as the second angle θ2. The second angle θ2 is represented as an angle formed by the mounting surface 21A and the virtual surface K along the X direction. In the present embodiment, the second angle θ2 is, for example, smaller than the first angle θ1.

The printer 1 has, as a main part, a transport unit 10 for transporting the medium P, a line head 20 for recording information on the medium P, and a head moving unit 30 for moving the line head 20 in the B direction.

As shown in FIGS. 1 and 2, the transport unit 10 has two pulleys 14, an endless transport belt 15 wound around the two pulleys 14, and a motor (not shown) for driving the pulleys 14. .. The transport unit 10 is an example of a support portion. The support surface of the transport belt 15 that supports the medium P constitutes a part of the transport path T. As shown in FIG. 2, the outer dimension D1 of the transport belt 15 wound around the two pulleys 14 in the X direction is smaller than the dimension D2 in the A direction of the support surface of the transport belt 15 that supports the medium P. In other words, of the horizontal outer dimensions of the transport belt 15 wound around the two pulleys 14, the outer dimension D1 in the direction orthogonal to the width direction of the transport belt 15 supports the transport belt 15 that supports the medium P. It is smaller than the dimension D2 in the A direction of the surface. The medium P is transported to a position facing the line head 20 while being attracted to the support surface of the transport belt 15. Therefore, as shown in FIG. 2, a charging roller 17 for charging the transport unit 10 and a static elimination brush 18 for statically eliminating the medium P supported by the transport unit 10 are provided in the housing 2. ..

The charging roller 17 is an example of a charging unit. The charging roller 17 charges the transport belt 15 by coming into contact with the transport belt 15. The charging roller 17 charges the transport belt 15 to attract the medium P to the support surface of the transport belt 15. The charging roller 17 is provided at a position on the + B direction side with respect to the endless transport belt 15 wound around the two pulleys 14. The charging roller 17 may be provided at a position where the transport belt 15 is sandwiched between the two pulleys 14 and the pulley 14 located on the −A direction side.

The charging roller 17 is in contact with the support surface of the transport belt 15, and is driven to rotate according to the operation of the transport belt 15. A power supply device (not shown) that applies a DC voltage to the charging roller 17 is connected to the charging roller 17, whereby the charging roller 17 supplies electric charge to a portion in contact with the conveyor belt 15. The power supply device is controlled by the control unit 26, and switches on / off the voltage application to the charging roller 17 and switches the voltage applied to the charging roller 17. In the present embodiment, the charging roller 17 supplies a positive charge to the transport belt 15 and charges the support surface of the transport belt 15 to a positive polarity.

The static elimination brush 18 is an example of a static elimination unit. The static elimination brush 18 eliminates static electricity by contacting the medium P supported by the transport belt 15. The static elimination brush 18 is provided at a position on the −B direction side with respect to the endless transport belt 15 wound around the two pulleys 14. The static elimination brush 18 is provided at a position on the −A direction side with respect to the discharge surface NA of the line head 20. The static elimination brush 18 may be provided at a position where the transport belt 15 is sandwiched between the pulley 14 located on the −A direction side of the two pulleys 14.

The static elimination brush 18 removes electric charges on the recording surface on the discharge surface NA side of the medium P. Alternatively, the static elimination brush 18 may remove charges on the support surface of the transport belt 15. More specifically, when a charge is applied to the support surface of the transport belt 15 by the charging roller 17, the medium P in contact with the support surface is charged with the opposite polarity on the surface in contact with the support surface, and further, the opposite side of the medium P is generated. A charge having the opposite polarity to that of the charge is also generated on the surface, that is, the recording surface. The electric charge on the recording surface side is removed by the static elimination brush 18. As a result, only the electric charge on the side in contact with the transport belt 15 remains on the medium P, and as a result, the medium P is adsorbed on the support surface.

The static elimination brush 18 may be made of any material as long as it can remove charges from the medium P and the transport belt 15, and can be formed of, for example, a resin material such as conductive nylon. The static elimination brush 18 is connected to a switching device (not shown), and the switching device is controlled by the control unit 26 to switch between a state in which the static elimination brush 18 is grounded, that is, a state in which it is grounded and a state in which it is not grounded.

In this way, the transport belt 15 supports the medium P while adsorbing the medium P. The support surface that supports the medium P in the transport belt 15 constitutes a region of the transport path T that faces the line head 20. That is, the transport unit 10 rotates by driving the pulley 14 and transports the medium P supported by the support surface of the transport belt 15 in the + A direction in the transport direction. At this time, the downstream side in the transport direction in the transport direction is above the upstream side in the transport direction. Further, the transport unit 10 is arranged to face the line head 20 in the B direction. As a method of sucking the medium P on the transport belt 15, a suction method such as an air suction method may be adopted.

The transport unit 10 may further include a driven roller 19 that suppresses the floating of the medium P from the support surface of the transport belt 15. In this case, the driven roller 19 is provided at a position on the −B direction side with respect to the endless transport belt 15 wound around the two pulleys 14. The driven roller 19 is provided at a position between the discharge surface NA of the line head 20 and the static elimination brush 18 in the A direction. The driven roller 19 is provided at a position where the medium P is sandwiched between the driven roller 19 and the transport belt 15, and rotates driven according to the movement of the medium P supported by the transport belt 15. The driven roller 19 may be made of a conductive material such as metal and may be grounded.

The line head 20 is an example of a head portion. Further, the line head 20 has a nozzle N for ejecting ink, which is an example of a liquid. Further, the line head 20 is arranged to face the transport unit 10 in the B direction at a recording position described later, and records information by ejecting ink from the nozzle N to the medium P transported in the transport direction. The line head 20 is an ink ejection head configured so that the nozzle N for ejecting ink covers the entire area in the Y direction as the width direction of the medium P. Further, the discharge surface NA on which the nozzle N is arranged is arranged along the A direction and the Y direction. As shown in FIG. 2, the discharge surface NA faces the + B direction. In the discharge surface NA, the dimension of the discharge surface NA in the Y direction is larger than the dimension of the discharge surface NA in the A direction. The discharge surface NA faces the + A direction side from the center of the support surface that supports the medium P in the transport belt 15 in the A direction. That is, the line head 20 is located in the + A direction from the center of the support surface that supports the medium P in the transport belt 15 in the A direction.

Further, the line head 20 is configured as an ink ejection head capable of recording in the entire width direction of the medium P without moving in the width direction of the medium P. However, the type of the ink ejection head is not limited to this, and may be a type that is mounted on the carriage and ejects ink while moving in the width direction of the medium P.

As shown in FIG. 4, the line head 20 extends in the Y direction. A plate portion 20A is projected toward the + A direction on the side portions in the + A direction at both ends of the line head 20 in the Y direction. Further, support frames 22 are attached to both ends of the line head 20 in the Y direction. The second maintenance unit 72 shown in FIG. 4 will be described later.

The support frame 22 is configured as a side plate along the AB surface and extends in the −B direction with respect to the line head 20. Cylindrical support pins 24 extending in the + Y direction and the −Y direction are provided at both ends in the B direction on the outer surface of the support frame 22 in the Y direction. An annular roller 25 is rotatably provided on the support pin 24.

Further, a support pin 27, a rack 28, and a coil spring 29 are provided on the inner surface of the support frame 22 in the Y direction. The support pin 27 protrudes from the support frame 22 in the Y direction.

The rack 28 is a plate-shaped member whose thickness direction is the Y direction, and extends in the B direction. A plurality of tooth portions 28A arranged in the B direction are formed at the end portion of the rack 28 in the −A direction. Further, the rack 28 is formed with an elongated hole 28B that penetrates in the Y direction and is long in the B direction. A support pin 27 is inserted through the elongated hole 28B. As a result, the rack 28 can move relative to the support frame 22 in the B direction.

One end of the coil spring 29 is attached to the support frame 22. The other end of the coil spring 29 is attached to the rack 28. As a result, the coil spring 29 exerts an elastic force in the B direction on the rack 28.

The line head 20 is detachable from the head moving portion 30 shown in FIG. 3 at the exchange position shown by the two-dot chain line in FIG. The replacement position is the position farthest from the transport unit 10 in the −B direction in the moving direction of the line head 20. Specifically, in the line head 20, the support frame 22 moved in the −B direction along the guide rail 37 described later is further pulled up in the + Z direction along the guide rail 38, so that the line head 20 is moved from the head moving portion 30. It is designed to be withdrawn.

The head moving unit 30 moves the line head 20 to a recording position and a retracting position, which will be described later, along the B direction. In other words, the head moving unit 30 moves the line head 20 in the B direction so that the moving direction of the line head 20 intersects both the vertical direction and the horizontal direction. Further, the moving direction is an inclined direction that intersects the horizontal plane at an angle greater than 0 degree and 45 degrees or less, and specifically, the angle at which the moving direction intersects the horizontal plane is 30 degrees.

As shown in FIGS. 3 and 5, the head moving portion 30 drives the main body frame 32 constituting the main body portion, the guide member 36 for guiding the line head 20 in the B direction, and the line head 20 described later in the B direction. It has a drive unit 40 and the like. Then, the head moving unit 30 moves the line head 20 to one or more of the evacuation positions described later, which are separated from the transport unit 10 with respect to the recording position described later. Specifically, the head moving portion 30 is provided so that the line head 20 can be moved to the first position, the second position, and the third position. The first position, the second position, and the third position will be described later.

The main body frame 32 is included in the housing 2. That is, the main body frame 32 is included in an example of the main body of the device. Specifically, the main body frame 32 has a side frame 33, a side frame 34, and a plurality of horizontal frames 35.

The side frame 33 and the side frame 34 are respectively configured as side plates along the AB surfaces, and are arranged so as to face each other at intervals in the Y direction. The side frame 33 is arranged on the + Y direction side, and the side frame 34 is arranged on the −Y direction side. The side frame 34 is formed with a through hole 34A for moving the second maintenance unit 72, which will be described later. The plurality of horizontal frames 35 connect the side frame 33 and the side frame 34 in the Y direction. Further, the line head 20 is arranged in the space surrounded by the plurality of horizontal frames 35.

The guide member 36 is an example of a guide portion, and one guide member 36 is provided on each of the side frame 33 and the side frame 34. The two guide members 36 are arranged substantially symmetrically with respect to the center of the main body frame 32 in the Y direction. Therefore, the guide member 36 in the −Y direction will be described, and the description of the guide member 36 in the + Y direction will be omitted.

As shown in FIG. 5, the guide member 36 is attached to the side surface of the side frame 34 in the + Y direction. The guide member 36 is formed with a guide rail 37 extending in the B direction and a guide rail 38 branching from a portion in the middle of the guide rail 37 and extending in the Z direction. Both the guide rail 37 and the guide rail 38 are grooves that open in the + Y direction. Further, the guide rail 37 and the guide rail 38 guide the roller 25 in the B direction or the Z direction.

As shown in FIG. 5, the side frame 34 is provided with a guide rail 71 that constitutes a cap moving portion 80, which will be described later. The guide rail 71 is also provided on the side frame 33. That is, a set of guide rails 71 is provided between the side frame 33 and the side frame 34. The set of guide rails 71 is formed in a groove shape that opens inward in the Y direction, and extends along the A direction. Further, one set of guide rails 71 movably supports a plurality of rollers 73, which will be described later, in the A direction. That is, the guide rail 71 guides the plurality of rollers 73 in the A direction, so that the first maintenance unit 62, which will be described later, can move in the A direction.

As shown in FIG. 5, the drive unit 40 includes a motor 41, a gear unit (not shown), a shaft 42, and a pinion 43, and the drive is controlled by the control unit 26. The shaft 42 extends in the Y direction. Both ends of the shaft 42 are rotatably supported by the side frame 33 and the side frame 34 shown in FIG. The pinion 43 is attached to both ends of the shaft 42 in the Y direction. A tooth portion 43A that meshes with the tooth portion 28A is formed on the outer peripheral portion of the pinion 43.

The motor 41 rotates the shaft 42 and the pinion 43 in one direction or the opposite direction via a gear portion (not shown). In this way, the drive unit 40 rotates the pinion 43 to move the line head 20 in the B direction.

As shown in FIG. 6, the printer 1 has a maintenance unit 60, a cap moving portion 80, a lid unit 90, and a rotating mechanism portion 100.

The maintenance unit 60 is an example of a storage unit that stores the nozzle N and maintains the nozzle N. Specifically, the maintenance unit 60 includes a first maintenance unit 62 capable of covering the nozzle N and a second maintenance unit 72 for cleaning by wiping the ink ejection surface NA in the nozzle N. The second maintenance unit 72 will be described later.

The first maintenance unit 62 is an example of a cap portion. Further, the first maintenance unit 62 includes a cap portion main body 63, a cap 64 that covers the nozzle N, and a flushing portion 66 that faces the nozzle N and receives ink ejected from the nozzle N. Further, the first maintenance unit 62 includes the cap 64 and the flushing portion 66 along the A direction, and by moving in the A direction, the cap 64 faces the nozzle N and the flushing portion 66 faces the nozzle N. And the opposite state. Further, the first maintenance unit 62 has a standby position on the −A direction side with respect to the line head 20, and has a standby position, a discharge position, and a cap position in order toward the + A direction.

The standby position is away from the cap position in the −A direction in the A direction. That is, the standby position is separated from the line head 20 with respect to the cap position and is located below the cap position. According to this, the waste liquid tube 16A connecting the first maintenance unit 62 and the waste liquid storage unit 16 can be easily arranged below the line head 20. Therefore, the waste liquid tube 16A is less likely to interfere with the line head 20 and the transport path T. Further, since the waste liquid tube 16A is unlikely to be bent at the cap position, the waste liquid from the first maintenance unit 62 can be easily collected in the waste liquid storage unit 16.

The discharge position is the position of the first maintenance unit 62 when the flushing portion 66 faces the nozzle N. The discharge position is separated from the standby position in the + A direction in the A direction.
