Strictly speaking, one end of the branch pipe 33 is connected to the second compartment 25a2), and the other end is connected to the manifold 32. A branch pipe 37 is branched from the middle of the branch pipe 33 connected to the second compartment 25a2. One end of the branch pipe 37 is connected to the first branch chamber 25a1, and the other end is in the middle of the branch pipe 33, that is, a T-shape provided closer to the manifold 32 than the check valve 41 (described later). It is connected to the joint 38.
The branch pipe 33 is an example of a “suction channel”. The branch pipe 37 is an example of a “blowing channel”.

The fan 31 is an axial blower typified by a propeller fan. When the rotation direction is switched between forward and reverse, an exhaust state in which each branch pipe 33 is exhausted and an air supply state in which each branch pipe 33 is supplied with air. Can take. Switching operation of the fan 31 ON / OFF and switching operation of the rotation direction of the fan 31 are operated by the fan drive switch 11 provided on the operation panel 7. Control unit 30
Switches the ON / OFF of the fan 31 and switches the rotation direction of the fan 31 based on the operation received by the fan drive switch 11. The fan 31 performs air supply / exhaust through the air supply / exhaust filter 42.

For the branch pipe 33 connected to a <b> 2, the check valve 41 is in the second compartment 25 rather than the T-shaped joint 38.
It is provided on the a2 side. These check valves 41 allow the air flow in the exhaust state of the fan 31 and prevent the air flow in the air supply state of the fan 31.

In the suction blower 21 configured as described above, when the fan 31 takes an exhaust state,
While the inside of the branch pipe 37 has a negative pressure and the check valve 41 provided in each branch pipe 33 allows the gas flow in the exhaust state of the fan 31, the inside of each branch pipe 33 has a negative pressure. Small area 2
The suction force acts on the hole 24 provided in 6a1, that is, the blowout area B, and the second small area 26a2 and the second area 26b to the fourth area 26d, that is, the hole 24 provided in the suction area A. On the other hand, when the fan 31 is in an air supply state, the first small area 26 is connected via the branch pipe 37.
a1, that is, the air is blown into the hole 24 provided in the blowout area B, but the check valve 41 provided in each branch pipe 33 prevents the gas flow in the supply state of the fan 31, so that the second small area 26
a2 and the hole 24 provided in the second area 26b to the fourth area 26d, that is, the suction area A
The air is not blown. Thus, the suction air blowing unit 21 is in a suction state in which a suction force is applied to the hole 24 provided in the suction area A when the fan 31 is in an exhaust state, and the fan 31 is in an air supply state. The air is blown into the holes 24 provided in the blowout area B, and the air is blown out from the holes 24 toward the placement surface 26.

4 to 6, a series of operations performed by the recording apparatus 1 after the recording medium M is placed on the table unit 6 and after the recording operation by the recording processing unit 3 until the recording medium M is removed from the table unit 6. The operation of will be described.

First, before the start of recording, the recording processing unit 3 is positioned at the rear end of the stage unit 2, and in this state, the recording medium M is mounted on the mounting surface 26 of the table unit 6. As will be described later, the recording unit 12 starts moving from the right front end with respect to the stage unit 2 during the recording operation. For this reason, the right front end portion of the mounting surface 26 is a reference position P corresponding to the recording start position of the recording unit 12 on the mounting surface 26. The operator places the recording medium M on the placement surface 26 such that the right front corner of the recording medium M is positioned at the reference position P regardless of the size of the recording medium M. Here, it is assumed that a recording medium M having a size covering the first area 26a to the third area 26c is placed (see FIG. 4A).

The operator operates the on-off valve 39 after placing the recording medium M on the placement surface 26. Here, since the recording medium M is placed in the first area 26a to the third area 26c, the operator opens the on-off valve 39 provided in the branch pipe 33 connected to the first chamber 25a to the third chamber 25c. In addition to the valve operation, the on-off valve 39 provided in the branch pipe 33 connected to the fourth chamber 25d is closed. Thereafter, the operator operates the fan drive switch 1 so that the fan 31 is in the exhaust state.
1 is operated. As a result, the suction blower 21 is in a suction state, and the first small area 26a1, the second small area 26a2, the second area 26b, and the third area 26 on which the recording medium M is placed.
A suction force acts on the hole 24 provided in c (see FIG. 4B). For this reason, the recording medium M
Is attracted to the mounting surface 26, and the recording medium M can be kept in a warp-free state. In addition, since the on-off valve 39 provided in the branch pipe 33 connected to the fourth chamber 25d is closed, air is sucked unnecessarily from the hole 24 of the fourth area 26d where the recording medium M is not placed. It is suppressed.

Subsequently, when the recording apparatus 1 receives a recording start instruction, the recording processing unit 3 moves from the rear end to the front end of the stage unit 2 (see FIG. 5C). By this movement, the recording unit 12 is positioned on the right side of the front end of the stage unit 2. When the recording processing unit 3 moves from the rear end to the front end of the stage unit 2, the presence or absence of an obstacle on the recording medium M may be inspected using a photo sensor or the like provided in the recording processing unit 3. Good.

Subsequently, the recording unit 12 performs an operation of ejecting UV ink and irradiating ultraviolet rays while moving forward or backward in the X-axis direction along the placement surface 26, and a line feed operation, that is, the recording processing unit 3 By alternately performing the movement from the front to the rear, the recording medium M is
A desired image is recorded (see FIG. 5D). Thus, the recording unit 12 starts moving from the right front end with respect to the stage unit 2 during recording. Of course, the design of where the recording unit 12 starts to move with respect to the stage unit 2 during recording can be arbitrarily changed.

After the recording operation is completed, the operator operates the fan drive switch 11 so that the fan 31 is in the air supply state. As a result, the suction blower 21 is in a blown state, and air is ejected from the hole 24 provided in the first small area 26a1 to the placement surface 26 side (see FIG. 6E).

As described above, according to the recording apparatus 1 of the present embodiment, the suction air blowing unit 21 is in the suction state,
While suction force is applied to the hole 24 provided in the suction area A and the hole 24 provided in the blowout area B, in the blown state, the blowout area does not blow air to the hole 24 provided in the suction area A. It blows with respect to the hole 24 provided in B. For this reason, compared with the case where it ventilates with respect to all the holes 24 provided in the mounting surface 26, the wind pressure from the hole 24 provided in the blowing area B can be enlarged. In other words, since the wind pressure from the hole 24 provided in the blowing area B can be increased without using the fan 31 having a large air flow rate, the recording medium M having a relatively heavy weight or the recording can be used. Even when the medium M is charged and electrostatically adsorbed to the mounting surface 26, the portion of the recording medium M that is mounted in the blowing area B can be lifted from the mounting surface 26. As a result, the operator can move between the floating recording medium M and the mounting surface 26.
A finger or the like can be easily inserted, and the recording medium M can be easily removed from the placement surface 26.

Moreover, according to this embodiment, since the blowing area B is provided including the reference position P, the recording medium M is placed in the blowing area B regardless of the size of the recording medium M. Therefore, regardless of the size of the recording medium M, the recording medium M can be lifted from the mounting surface 26 and can be easily removed from the mounting surface 26.

Then, the modification of the suction ventilation part 21 is demonstrated. The suction air blowing unit 21 according to the modified example is
Although it is comprised substantially the same as the suction ventilation part 21 mentioned above, it differs in the point which uses the centrifugal blower represented by the sirocco fan as the fan 31. FIG. Hereinafter, different points will be mainly described.

As shown in FIG. 7, the suction blower 21 of the modified example has a discharge pipe 5 that is continuous with the exhaust side of the fan 31.
1 and a switching valve 52 provided in the middle of the branch pipe 37, while each branch pipe 33 is not provided with a check valve 41. In the following description, the first value is higher than the switching valve 52 of the branch pipe 37.
The side of the branch chamber 25a1 is referred to as a branch pipe tip portion 37a, and the branch pipe 33 rather than the switching valve 52 of the branch pipe 37.
The side is referred to as a branch pipe base end portion 37b.
The discharge pipe 51 is an example of a “discharge channel”.

The switching valve 52 is configured by a 5-port valve, and includes a first port 52a to which the branch pipe distal end portion 37a is connected, a second port 52b to which the branch pipe proximal end portion 37b is connected, and a fan for the discharge pipe 51. 31 is provided with a third port 52c, an intake port 52d, and an exhaust port 52e, to which an end opposite to 31 is connected. The intake port 52 d is connected to the intake filter 53, and the exhaust port 52 e is connected to the exhaust filter 54.

The switching valve 52 has a first state in which the first port 52a is in communication with the second port 52b and the third port 52c is in communication with the exhaust port 52e, and the intake port 52d is in the second port 52.
a second state in which the third port 52c communicates with the first port 52a, and the third port 52c communicates with the first port 52a.
Switch between.

In the suction air blowing section 21 configured as described above, when the switching valve 52 is switched to the first state, the first port 52a communicates with the second port 52b, and the third port 52c communicates with the exhaust port 52e. Therefore, the inside of each branch pipe 33 and the inside of the branch pipe 37 become negative pressure, and the second small area 2
6a2 and the second area to the fourth area 26d, that is, the hole 24 provided in the suction area A,
A suction force acts on the first small area 26a1, that is, the hole 24 provided in the blowing area B. On the other hand, when the switching valve 52 is switched to the second state, the intake port 52d is connected to the second port 52.
b, and the third port 52c communicates with the first port 52a, so that the gas sucked from the intake port 52d flows into the branch pipe base end portion 37b, the branch pipe 33, the discharge pipe 51, and the branch pipe distal end portion 3.
The air is blown into the hole 24 provided in the blowing area B through 7a. Thus, also about the suction ventilation part 21 of a modification, it will be in a suction state by the switching valve 52 switching to a 1st state,
When the switching valve 52 is switched to the second state, the ventilation state is established. In other words, even when the fan 31 that does not change the blowing direction even if the rotation direction is changed, such as a centrifugal blower, the suction blowing unit 21 that can take the suction state and the blowing state can be realized. Of course, it is also possible to use an axial blower in the suction blower 21 of the modified example.

The recording unit is not particularly limited, and, for example, a unit that ejects ink by an inkjet method can be used. As the ink, in addition to general water-based ink and oil-based ink, electromagnetic wave curable ink that is cured by irradiation with X-rays, ultraviolet rays, visible rays, infrared rays, or the like can be used.

The moving unit may be configured to move the recording unit relative to the table unit 6, may be configured to move the table unit relative to the recording unit, or may be configured to move both the table unit and the recording unit. . Further, a serial system in which the recording unit is relatively moved in two directions substantially orthogonal to the recording medium or a line system in which the recording unit is relatively moved in one direction may be used.
