As shown in FIG. 8, the moving mechanism section cover 80 extends in the X-axis direction and is positioned on the + Z-axis direction side of the base 50, guide rails 54 and 54, detectors 56 and 58, and the drive mechanism 60. Further, as shown in FIGS. 8 and 9, the + Y-axis direction end 80a of the moving mechanism section cover 80 extends to the + Z-axis direction side and extends to a position in the Z-axis direction where the medium support section 42 is provided. Yes.

  Therefore, when a recording medium such as a T-shirt placed on the medium support unit 42 falls from the medium support unit 42, the recording medium does not come into contact with the moving mechanism unit 44, so that the recording medium moves. The possibility of being damaged by being caught in the drive mechanism of the mechanism unit 44 can be reduced or prevented from being damaged.

  Next, referring to FIG. 9, an obstacle detection sensor 82 is provided in the housing 16 of the recording unit 12. The obstacle detection sensor 82 detects whether or not there is an obstacle in the medium support part 42 when the medium support part 42 is moved from the position Y1 to the position Y2 by the moving mechanism part 44. Here, the obstacle refers to an obstacle or at least one of the recording head 32 and the recording medium when it comes into contact with the recording head 32, such as dust and dirt adhering to the recording medium, wrinkles or floating of the recording medium. It means something that can cause defects.

  In other words, the obstacle detection sensor 82 determines whether or not the height of the recording medium or foreign matter placed on the medium support portion 42 is a height that can contact the recording head 32 of the carriage 22 in FIG. To detect. Detection information such as floating of the recording medium detected by the obstacle detection sensor 82 is transmitted to the control unit 84. When it is determined that there is an obstacle on the medium support unit 42 based on the detection information, the control unit 84 controls the medium support unit 42 to return from the position Y2 to the position Y1 via the moving mechanism unit 44.

<<< Operation of Medium Support Unit and Movement Mechanism Unit >>>
Next, operations of the medium support unit 42 and the movement mechanism unit 44 will be described with reference to FIGS. 10 to 17. The medium support unit 42 and the moving mechanism unit 44 reciprocate by driving the endless belt driving unit 52 from a position Y1 (first end) in FIG. 10 to a position Y2 (second end) in FIG. It is configured to be possible.

  As step S <b> 1 in FIG. 13, the user presses a single operation switch 30 (see FIG. 1) of the operation unit 20. Next, in step S2, the control unit 84 causes the detectors 56 and 58 to detect the detection unit 78, and confirms whether the medium support unit 42 is located at either the position Y1 or the position Y2.

  In step S3, when the medium support portion 42 is located at the position Y1, the medium support portion 42 is moved from the position Y1 toward the position Y2 as shown in FIG. 14 and accelerated until the first speed V1 is reached. Let In the present embodiment, as an example, the first speed V1 is set to 7 inches / second. Further, when the medium support unit 42 is moved from the position Y1 toward the position Y2, the position passes through the position Y3 (detection position of the detector 56), so the control unit 84 is based on signals from the detector 56 and the encoder 74. Then, the moving distance of the medium support unit 42 is monitored. In step S4, the medium support unit 42 is moved by the distance L3 from the position Y3 (detection position of the detector 56) at the first speed V1, and then the medium support unit 42 is decelerated.

  Further, when the medium support part 42 is moved from the position Y3 to the position Y4 that is a distance L3 away from the position Y3, the obstacle detection sensor 82 detects whether or not an obstacle exists in the medium support part 42.

  Further, after the medium support portion 42 has passed the position where the carriage 22 is provided in the Y-axis direction in FIG. 10, the carriage 22 is moved to the end portion (home position) of the moving region of the carriage 22 in FIG. ) To the flushing position on the + X axis direction side. By operating the carriage 22 in this way, the recording operation time per sheet in the recording apparatus 10 can be shortened as compared with the case where the carriage 22 is operated with the medium support portion 42 stopped at the position Y2.

  In step S5, the medium support unit 42 is stopped at the position Y2. In the state where the medium support unit 42 and the moving mechanism unit 44 are stopped at the position Y2, the end 80a of the moving mechanism unit cover 80 provided in the moving mechanism unit 44 is close to the moving unit protective cover 46.

  In step S6, when it is determined that there is an obstacle in the medium support part 42 based on the detection information of the obstacle detection sensor 82, the medium support part 42 stopped at the position Y2 is moved to the set position Y1. When it is determined that no obstacle exists in the medium support unit 42, a recording operation to the recording medium is executed. The recording operation will be described later from step S12 to step S14.

  When there is an obstacle in the medium support section 42, as shown in FIG. 15 as step S7, the medium support section 42 is moved from the recording start position Y2 toward the set position Y1 and accelerated to the first speed V1. .

  Further, when the medium support unit 42 is moved toward the position Y1, it passes through the position Y4 (detection position of the detector 58), so that the control unit 84 supports the medium based on the signals from the detector 58 and the encoder 74. The moving distance of the unit 42 is monitored. Then, as step S8, after the medium support portion 42 is moved at the first speed V1 from the position Y4 (detection position of the detector 58) to the position Y6 (see FIG. 15) separated by the distance L4 in the −Y axis direction side. Then, the medium support unit 42 is decelerated from the first speed V1.

  In other words, in the present embodiment, the medium support portion 42 is decelerated from the position Y6 at a predetermined distance L2 + L4 from the position Y2. This position is located on the position Y2 side of the detection position Y3 of the detector 56, and is set to a position where the medium support portion 42 can be surely decelerated from the first speed V1 up to the position Y1.

  In addition, the deceleration start position when the medium support portion 42 moves toward the first end is the position Y6. That is, the position Y6 is set as a position away from the position Y1 by a predetermined distance from the position Y2. For this reason, the distance L8 between the position Y1 and the position Y6 is longer than the distance L2 (see FIG. 14) from the deceleration start position Y4 to the stop position Y2 when the medium support portion 42 moves toward the second end. Is set.

  In step S9, the medium support unit 42 is stopped at a position Y5 (see FIG. 15) separated from the position Y4 (detected position of the detector 58) by a distance L5. Next, in step S10, the control unit 84 moves the medium support unit 42 stopped at the position Y5 toward the position Y1, and moves it to the set position Y1 at the second speed V2. In the present embodiment, the position Y5 is the moving mechanism 44 in the moving section 14 when the front end 42a of the medium support section 42 is at the same position as the front end 40a of the base 40 in the Y-axis direction in FIG. Is the position. In the present embodiment, as an example, the second speed V2 is set to 2.45 inches / second.

  Then, the control unit 84 stops the medium support unit 42 at the set position Y1. At this time, the control unit 84 displays that the obstacle detection sensor 82 has confirmed the abnormality on the display means such as a liquid crystal panel provided in the operation unit 20, and re-records the recording medium supported by the medium support unit 42. Users can be prompted to set or replace.

  Further, as shown in FIG. 10, detectors 56 and 58 are arranged at a position Y3 on the −Y axis direction side (first end portion) and a position Y4 on the + Y axis direction side (second end portion), respectively. Therefore, the medium support portion 42 can be detected on the −Y axis direction side (first end portion) and the speed can be surely reduced. Furthermore, in this embodiment, when the medium support portion 42 is moved from the + Y-axis direction side (second end) to the −Y-axis direction side (first end), the medium is moved between the position Y1 and the position Y2. Since the support portion 42 is temporarily stopped, the medium support portion 42 can be reliably decelerated on the −Y axis direction side. As a result, it is possible to reduce the possibility that the article located on the position Y1 side and the recording apparatus 10 are damaged.

  Further, when the medium support unit 42 and the movement mechanism unit 44 are moved from the + Y axis direction side to the −Y axis direction side, the medium support unit 42 and the movement mechanism unit 44 are temporarily stopped at the position Y5 and then the first speed V1. Since it is moved toward the −Y-axis direction side at the lower second speed V2, the safety of the recording apparatus 10 can be further improved.

  Here, the position Y5 is set to a position where the medium support portion 42 and the moving mechanism portion 44 do not protrude from the front end portion 40a of the base 40 to the −Y axis direction side in the Y axis direction. Further, when the medium support part 42 and the movement mechanism part 44 move so as to protrude to the −Y axis direction side from the front end part 40a of the base 40, the medium support part 42 and the movement mechanism part 44 move at the second speed V2. Is set to As a result, it is possible to reduce the possibility that the article located on the position Y1 side and the recording apparatus 10 are damaged.

  Next, a case where there is no obstacle on the recording medium supported by the medium support unit 42 in step S6 will be described. In step S12, as shown in FIG. 16, the control unit 84 accelerates the medium support unit 42 to the third speed V3 while moving the medium support unit 42 from the recording start position Y2 toward the set position Y1. In the present embodiment, as an example, the third speed V3 is set to 6 inches / second.

  At this time, after flushing the recording head 32 at the flushing position (the end portion on the X-axis direction side of the moving region of the carriage 22 in FIG. 4), the recording head 32 (see FIG. 2) is moved to the medium support portion 42. Is moved to a position facing the recording medium supported by the recording medium.

  Further, when the medium support unit 42 is moved toward the position Y1, it passes through the position Y4 (detection position of the detector 58), so that the control unit 84 supports the medium based on the signals from the detector 58 and the encoder 74. The moving distance of the unit 42 is monitored. In step S13, the control unit 84 executes the recording operation execution mode for the carriage 22 and the recording head 32 (see FIG. 2) when the medium support unit 42 reaches a position (recording operation execution position) at a distance L7 from the recording start position Y2. Then, recording on the recording medium is performed.

  In this embodiment, during the recording operation, the medium support unit 42 and the moving mechanism unit 44 are intermittent feeding operations that alternately perform a feeding operation and a pause operation toward the position Y1 in the recording execution area. 2 moves in the -Y-axis direction.

  During execution of the recording operation execution mode, the control unit 84 moves the medium support unit 42 and the moving mechanism unit 44 to the −Y axis direction side in FIGS. 10 to 12 by the endless belt driving unit 52. At this time, the endless belt drive unit 52 moves the medium support unit 42 and the movement mechanism unit 44 only in the −Y axis direction side.

  Accordingly, when the recording operation execution mode is executed, the medium support unit 42 and the movement mechanism unit 44 are moved from the position Y2 side to the position Y1 side. Therefore, in the movement mechanism unit 44 that moves the medium support unit 42 Since the influence of the backlash and the extension of the timing belt 64 can be suppressed and the medium support portion 42 can be moved with high accuracy, the accuracy of transport of the recording medium can be improved, that is, the recording accuracy to the recording medium can be improved. Can be made.

  Next, in step S14, when the medium support portion 42 reaches a position Y6 (see FIG. 16) that is a distance L4 away from the position Y4, the recording operation execution mode is terminated, and the medium support portion 42 is decelerated from the third speed V3. Let And the operation | movement from step S9 to step S11 is performed.

  Also in the recording operation execution mode, the deceleration start position when the medium support portion 42 moves toward the first end is the position Y6. That is, the position Y6 is set as a position away from the position Y1 by a predetermined distance from the position Y2. For this reason, the distance L8 between the position Y1 and the position Y6 is longer than the distance L2 (see FIG. 14) from the deceleration start position Y4 to the stop position Y2 when the medium support portion 42 moves toward the second end. Is set.

  When the second recording on the recording medium is performed again after the first recording on the recording medium, the process from step S1 to step S6, from step S12 to step S14, and from step S9 to step S11. Perform the operation again. A configuration in which the operation switch 30 of the operation unit 20 is pressed again when performing the second recording, or a configuration in which the control unit 84 automatically executes the second recording operation immediately after the medium support unit 42 stops at the position Y1. can do.

  Further, when the recording operation execution mode is executed, the backlash of the movement mechanism unit 44 that moves the medium support unit 42 by moving the medium support unit 42 and the movement mechanism unit 44 from the position Y2 side to the position Y1 side. Since the influence is suppressed, the deviation between the first recording start position and the second recording start position on the recording medium can be suppressed or prevented, so that the recording quality and image quality on the recording medium are improved. be able to.

  Next, when the medium support portion 42 is not detected at the position Y1 in step S2, and the medium support portion 42 is detected at the position Y2 in step S15, the operations from step S8 to step S11 are executed to execute the medium support portion 42. Is moved from position Y2 to position Y1.

  In addition, the medium support portion 42 may not be detected by the detectors 56 and 58 in step S2 and step S15. Specifically, this is a case where the medium support portion 42 is located between the position Y3 and the position Y4. In this case, the position of the medium support portion 42 in the Y-axis direction is unknown. Accordingly, as shown in FIG. 17 as step S16, the medium support portion 42 is slowly moved toward the position Y1 at the second speed V2. In step S17, the medium support unit 42 is stopped at the position Y1.

  Even if the medium support portion 42 is not detected by the detectors 56 and 58 at either the position Y1 or the position Y2, that is, even when the position of the medium support portion 42 is unknown in the Y-axis direction, the second velocity V2 toward the position Y1. Therefore, even if the article positioned around the position Y1 collides with the medium support section 42, the possibility that the article and the medium support section 42 are damaged can be reduced.

  Further, when the user presses the operation switch 30 while the medium support unit 42 and the movement mechanism unit 44 are moving in the + Y axis direction side and in the −Y axis direction side in FIG. The mechanism unit 44 stops moving. When the operation switch 30 is pressed after the movement of the medium support unit 42 and the movement mechanism unit 44 is stopped or when the medium support unit 42 and the movement mechanism unit 44 are stopped, the medium support unit 42 and the movement mechanism unit 44 are moved. Move toward the position Y1.

  At this time, when it is detected that the medium support part 42 and the movement mechanism part 44 are located at the position Y2, step S15 is executed, and the medium support part 42 moves toward the position Y1. When the medium support unit 42 and the moving mechanism unit 44 are not detected by the detectors 56 and 58 and the position is unknown between the position Y3 and the position Y4, step S16 is executed and the medium support unit 42 is positioned. Move towards Y1.

  Further, in this embodiment, the medium support portion 42 between the −Y axis direction side (first end portion) and the + Y axis direction side (second end portion) is operated by operating the single operation switch 30. In addition, since a preset operation is executed in accordance with the position of the moving mechanism unit 44, the user does not need to perform complicated operations in accordance with the positions of the medium support unit 42 and the moving mechanism unit 44. Can be improved.

  When the medium support unit 42 and the moving mechanism unit 44 are moved to the −Y axis direction side, the medium support unit is moved from the −Y axis direction side to the + Y axis direction side and from the −Y axis direction side to the + Y axis direction side. 42 and the moving mechanism 44 are decelerated from the position Y6 separated by a predetermined distance longer than the deceleration distance of the medium supporting 42 and the moving mechanism 44 when the moving mechanism 42 and the moving mechanism 44 are moved. The medium support part 42 and the moving mechanism part 44 that approach the Y-axis direction side move at a low speed. Accordingly, since the speed is slower than when the medium support unit 42 and the movement mechanism unit 44 are moved at a high speed, even if an article located around the position Y1 collides with the medium support unit 42 and the movement mechanism unit 44. The possibility that the article and medium support portion 42 and the moving mechanism portion 44 are damaged can be reduced. Further, since the medium support portion 42 and the moving mechanism portion 44 move to the position Y2 opposite to the position Y1 at high speed, the moving time can be shortened. Thereby, the working time per unit number of recording media in the recording apparatus 10 can be shortened.

  When the medium support unit 42 and the moving mechanism unit 44 are positioned between the −Y axis direction side (first end) and the + Y axis direction side (second end), the −Y axis direction side Since the article moves at a low speed toward the first end, even if the article located around the position Y1 collides with the medium support part 42 and the movement mechanism part 44, the article and medium support part 42 and The possibility that the moving mechanism 44 is damaged can be reduced.

  In the present embodiment, the obstacle detection sensor 82 monitors whether or not the obstacle such as the recording medium supported by the medium support portion 42 and the recording head 32 of the carriage 22 interfere with each other, and the medium support portion. 42 and the moving mechanism 44 in the Y-axis direction in FIG. 9 are monitored and controlled by the control unit 84 based on the detection signals of the detectors 56 and 58 and the signal from the encoder 74. The movement of the moving mechanism 44 in the Y-axis direction in FIG. 9 and the movement of the carriage 22 in the X-axis direction in FIG. 9 do not interfere with each other.

  Therefore, at least one of the collision between the medium support portion 42 and the carriage 22 and the collision between the medium support portion 42 and the recording head 32 can be suppressed. In addition, by setting the movement start timings of the carriage 22 and the medium support portion 42 so as not to interfere with each other, the recording operation execution time in the recording apparatus 10 can be shortened.
