[0008] First, the present invention will be briefly described. A recording device according to a first aspect of the present invention for solving the above problems includes a mounting section that supports a medium, a recording section that records on the medium supported on the mounting section, an adjustment mechanism that adjusts the position of the mounting section in a first direction in which the recording section and the mounting section face each other, a movement mechanism that moves the mounting section in a second direction that intersects with the first direction, a medium detection section that can detect whether the medium mounted on the mounting section is at a reference position in the first direction at a detection position within a movement range of the mounting section by the movement mechanism, an input section that accepts input of instructions, a notification section that notifies information, and a control section, wherein the control section, when adjusting the position of the mounting section in the first direction, uses the first instruction accepted by the input section In response to a second instruction received by the input unit, the control unit executes a first operation of moving the placement unit to a first position using the moving mechanism so that at least a portion of the placement unit is located at the detection position, causing the medium detection unit to detect whether the medium is at the reference position at the first position, and causing the notification unit to notify information based on the detection result of the medium detection unit; and after the first operation is completed, in accordance with a second instruction received by the input unit, the control unit executes a second operation of moving the placement unit using the moving mechanism so that the entire area of ​​the placement unit in the second direction passes through the detection position, causing the medium detection unit to detect whether the medium is at the reference position while the medium is passing through the detection position, and causing the notification unit to notify information based on the detection result of the medium detection unit.

[0009] According to this aspect, in the first operation, the movement mechanism moves the placement unit to a first position so that at least a portion of the placement unit is located at the detection position, the medium detection unit detects whether the medium is at the reference position at the first position, and the notification unit notifies information based on the detection result of the medium detection unit. That is, the placement unit is moved to the first position, and height adjustment of the placement unit can be completed at the first position. Therefore, the placement unit can be completed without having to move the placement unit back and forth multiple times in the second direction, thereby reducing the load associated with adjusting the height of the placement unit.

[0010] A second aspect of the recording device of the present invention is characterized in that, in the first aspect, when the medium detection unit does not detect that the medium is at the reference position during the first operation, the control unit notifies the notification unit of information prompting the adjustment mechanism to move the position of the placement unit in the first direction in a direction closer to the recording unit.

[0011] According to this aspect, if the medium detection unit does not detect that the medium is at the reference position in the first operation, the notification unit issues information urging the user to use the adjustment mechanism to move the position of the placement unit in the first direction toward the recording unit. Therefore, the user can easily move the placement unit to the reference position by following the information reported by the notification unit.

[0012] A third aspect of the recording device of the present invention is characterized in that, in the first or second aspect, the control unit causes the notification unit to notify the fact that the medium is at the reference position when the medium detection unit detects that the medium is at the reference position during the first operation.

[0013] According to this aspect, when the medium detection unit detects that the medium is in the reference position in the first operation, the notification unit notifies the user that the medium is in the reference position, allowing the user to properly recognize that the medium is in the reference position.

[0014] A fourth aspect of the recording device of the present invention is characterized in that, in the third aspect, when the medium detection unit does not detect that the medium is at the reference position in the first operation, the control unit repeats detection by the medium detection unit in the first operation and notification by the notification unit until the medium detection unit detects that the medium is at the reference position in the first operation, and when the medium detection unit detects that the medium is at the reference position in the first first operation, the control unit notifies the notification unit with information that the medium is at the reference position, as well as information urging the notification unit to use the adjustment mechanism to move the position of the placement unit in the first direction away from the recording unit, and information urging the notification unit to end the first operation.

[0015] According to this aspect, the first operation is repeated until the medium detection unit detects that the medium is in the reference position during the first operation. This ensures that the medium is in the reference position. Note that if the medium detection unit detects that the medium is in the reference position during the initial first operation, there is a risk that the position of the placement unit in the first direction is too close to the recording unit. However, if the medium detection unit detects that the medium is in the reference position during the initial first operation, the notification unit notifies the user that the medium is in the reference position, as well as information urging the user to use the adjustment mechanism to move the placement unit in the first direction away from the recording unit, and information urging the user to end the first operation. This prevents the user from mistakenly believing that the placement unit in the first direction is appropriate when the placement unit is too close to the recording unit.

[0016] A fifth aspect of the recording device of the present invention is characterized in that, in the fourth aspect, the control unit notifies information prompting the user to end the first operation, terminates the first operation in response to an instruction to end the first operation received by the input unit, and causes the notification unit to notify information prompting the user to start the second operation.

[0017] According to this aspect, information urging the user to end the first action is notified, the first action is ended in response to an instruction to end the first action received by the input unit, and information urging the user to start the second action is notified by the notifying unit, so that the second action can be started promptly after the first action is ended.

[0018] A sixth aspect of the recording device of the present invention is characterized in that, in any one of the third to fifth aspects, it includes a placement section detection section capable of detecting the position of the placement section in the first direction, and the control section, after the medium detection section detects that the medium is at the reference position in the first operation, causes the notification section to notify information prompting the adjustment mechanism to adjust the position of the placement section until the position of the placement section detected by the placement section detection section becomes a position that is a first distance away from the reference position in a direction away from the recording section.

[0019] According to this aspect, after the medium detection unit detects that the medium is at the reference position in the first operation, the notification unit issues information prompting the adjustment mechanism to adjust the position of the mount unit until the position of the mount unit detected by the mount unit detection unit becomes a position that is a first distance away from the reference position in the direction away from the recording unit in the first direction. Therefore, the detection result of the mount unit detection unit can be used to accurately adjust the position of the mount unit in the first direction.

[0020] A seventh aspect of the recording device of the present invention is characterized in that, in any one of the first to sixth aspects, when the medium detection unit detects that the medium is at the reference position during the second operation, the control unit causes the notification unit to notify the user that the medium is at the reference position, and causes the notification unit to notify the user of the following information: stopping the movement of the placement unit by the moving mechanism, and using the adjustment mechanism to move the position of the placement unit in the first direction away from the recording unit; and resuming the second operation after adjusting the position of the placement unit.

[0021] According to this aspect, when the medium detection unit detects that the medium is at the reference position during the second operation, the notification unit notifies the user that the medium is at the reference position, and the movement of the mounting unit by the movement mechanism is stopped. This prevents the medium from being at the reference position during the second operation, i.e., the mounting unit and the recording unit being too close in the first direction, resulting in contact between the medium and the recording unit when the recording operation is performed. The notification unit also notifies the user with information urging the user to use the adjustment mechanism to move the position of the mounting unit in the first direction away from the recording unit, and information urging the user to resume the second operation after adjusting the position of the mounting unit. This allows the distance in the first direction between the mounting unit and the recording unit to be within an appropriate range.

[0022] An eighth aspect of the recording device of the present invention is characterized in that, in the seventh aspect, the control unit, in response to an instruction to resume the second operation received by the input unit, temporarily moves the stopped placement unit to a position where the second operation can be started from the beginning using the moving mechanism, and resumes the second operation.

[0023] According to this aspect, in response to an instruction to resume the second operation received by the input unit, the stopped mounting unit is temporarily moved by the movement mechanism to a position where the second operation can be started from the beginning, and the second operation is resumed. Therefore, when the second operation is resumed, the second operation can be performed again over the entire area of ​​the mounting unit in the second direction, and contact between the medium and the recording unit can be particularly preferably suppressed.

[0024] A ninth aspect of the recording device of the present invention is characterized in that, in the seventh aspect, the control unit, in response to an instruction to resume the second operation received by the input unit, resumes the second operation of the stopped placement unit by continuing from the stopped position in the second direction.

[0025] According to this aspect, in response to an instruction to resume the second operation received by the input unit, the second operation is resumed by continuing the stopped position of the placement unit in the second direction, thereby reducing the time required to resume the second operation.

[0026] A tenth aspect of the recording device of the present invention is characterized in that, in the ninth aspect, the control unit, in response to an instruction to resume the second operation received by the input unit, moves the placement unit in the second direction using the moving mechanism relative to the stopped placement unit so that the area of ​​the placement unit that is at the detection position in the second direction can be re-detected by the media detection unit, and then resumes the second operation.

[0027] According to this aspect, in response to an instruction to resume the second operation received by the input unit, the movement mechanism moves the placement unit in the second direction so that the area of ​​the placement unit that is at the detection position in the second direction can be re-detected by the medium detection unit with respect to the stopped placement unit, and then the second operation is resumed. This makes it possible for the medium detection unit to re-detect the position that caused the placement unit to stop, thereby particularly effectively suppressing contact between the medium and the recording unit.

[0028] An 11th aspect of the recording device of the present invention is characterized in that, in any one of the first to tenth aspects, the control unit automatically moves the placement unit to an initial position using the moving mechanism when the medium detection unit does not detect that the medium is at the reference position during the second operation.

[0029] According to this aspect, if the medium detection unit does not detect that the medium is at the reference position during the second operation, the movement mechanism automatically moves the mounting unit to the initial position. Therefore, if the position of the mounting unit in the first direction is appropriate, the next operation to be executed, such as a recording operation, can be started promptly.

[0030] A twelfth aspect of the present invention provides a control method for a recording device including a mounting section that supports a medium, a recording section that records on the medium supported on the mounting section, an adjustment mechanism that adjusts the position of the mounting section in a first direction in which the recording section and the mounting section face each other, a movement mechanism that moves the mounting section in a second direction that intersects with the first direction, a medium detection section that can detect whether the medium mounted on the mounting section is at a reference position in the first direction at a detection position within a movement range of the mounting section by the movement mechanism, an input section that accepts input of instructions, and a notification section that notifies information, wherein when adjusting the position of the mounting section in the first direction, the method includes: a first operation in which, in response to a first instruction, the movement mechanism moves the placement unit to a first position so that at least a portion of the placement unit is located at the detection position, the medium detection unit detects whether the medium is at the reference position at the first position, and the notification unit notifies the notification unit of information based on the detection result of the medium detection unit; and a second operation in which, after the first operation, in response to a second instruction received by the input unit, the movement mechanism moves the placement unit so that the entire area in the second direction of the placement unit passes through the detection position, and the medium detection unit detects whether the medium is at the reference position while the medium is passing through the detection position, and the notification unit notifies the notification unit of information based on the detection result of the medium detection unit. The present invention is characterized by carrying out the following.

[0031] According to this aspect, in the first operation, the movement mechanism moves the placement unit to a first position so that at least a portion of the placement unit is located at the detection position, the medium detection unit detects whether the medium is at the reference position at the first position, and the notification unit notifies information based on the detection result of the medium detection unit. That is, the placement unit is moved to the first position, and height adjustment of the placement unit can be completed at the first position. Therefore, the placement unit can be completed without having to move the placement unit back and forth multiple times in the second direction, thereby reducing the load associated with adjusting the height of the placement unit.

[0032] A recording device 1 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. First, an overview of the recording device 1 of this embodiment will be described mainly with reference to Figs. 1 to 3. Fig. 1 is a schematic perspective view of the recording device 1, Fig. 2 is a schematic front view of the recording device 1, and Fig. 3 is a schematic plan view of the recording device. Note that Figs. 1 to 3 all show a simplified state of some of the components.

[0033] Specifically, the recording device 1 of this embodiment is an inkjet printer. The recording device 1 includes a medium support unit 2 that moves in a movement direction A while supporting a medium. The medium support unit 2 has a tray 4 as a mounting unit that supports the medium by placing it on a mounting surface 8. The recording device 1 includes a medium transport unit 3 as a moving mechanism that transports the medium supported by the tray 4 in the movement direction A. The movement direction A includes a direction A1 and a direction A2 opposite to the direction A1. The tray 4 is detachably mounted on a stage 5 that serves as a base unit. Here, the direction in which the tray 4 is attached to and detached from the stage 5 is vertical in the recording device 1 of this embodiment. The lever 9 is used to adjust the height of the tray 4, i.e., the distance between the tray 4 and the recording head 7 in a facing direction C. Here, the facing direction C refers to the direction in which the tray 4 and the recording head 7 face each other during recording.

[0034] As shown in FIG. 7 and other figures, the stage 5 has a protrusion 14 extending downward in the vertical direction. A stepped protrusion support portion 15, shown in FIG. 8, is formed inside the lever 9. The protrusion support portion 15 is the portion on which the protrusion 14 of the stage 5 is placed. That is, the lever 9 supports the stage 5 by supporting the protrusion 14 with the protrusion support portion 15. By rotating the lever 9, the position where the protrusion 14 is placed on the protrusion support portion 15 changes, and the tray 4 moves together with the stage 5 in the opposing direction C. In this embodiment, the opposing direction C is the vertical direction. The lever 9 is manually operated by the user. As shown in FIG. 2, the lever 9 is provided on an arm portion 10 of the medium support unit 2. Various materials can be used as the medium, including textiles such as woven fabrics and cloth, as well as paper and polyvinyl chloride resin.

[0035] As described above, the lever 9 is configured to be able to adjust the support position of the medium in the facing direction C by moving the tray 4 in the facing direction C. Therefore, the lever 9 can be said to be an adjustment mechanism. In this embodiment, the lever 9 is configured to move the tray 4 and stage 5, which are part of the medium support unit 2, but is not limited to this configuration. For example, it may be configured to move only the tray 4.

[0036] 1 to 3, a medium detection unit 40 capable of detecting a medium placed on tray 4 at a predetermined position in the facing direction C is provided inside the main body of recording device 1. In this embodiment, medium detection unit 40 includes a light-emitting unit and a light-receiving unit arranged along width direction B, and is configured to be able to detect the medium in a non-contact manner based on whether light emitted from the light-emitting unit is received by the light-receiving unit. However, medium detection unit 40 is not limited to this configuration, and may be configured, for example, to have a contact unit for the medium and be able to detect the medium based on whether the contact unit comes into contact with the medium placed on tray 4.

[0037] 1 to 3, the recording device 1 is formed with an operation panel 41 having a display unit 41a and various buttons 41b, and various information such as the detection results by the medium detection unit 40 is displayed on the display unit 41a of the operation panel 41. The user can then input various instructions using the various buttons 41b and the display buttons displayed on the display unit 41a in accordance with the content of the information displayed on the display unit 41a. The various buttons 41b serve as an input unit for inputting information, but the display unit 41a can also display display buttons and the like, so it also serves as an input unit.

[0038] The recording device 1 also includes a recording head 7 as a recording unit inside its main body, which is capable of ejecting ink, an example of a liquid, to form an image on a medium. "Forming an image on a medium" is another way of saying "recording an image on a medium." In this embodiment, the ejection direction, which is the direction in which ink is ejected from the recording head 7, is a vertical direction. Ink is supplied to the recording head 7 from multiple ink cartridges, each for a different color. The recording device 1 of this embodiment is capable of reciprocating a carriage 6 equipped with the recording head 7 in a width direction B, which intersects with the movement direction A. While reciprocating the recording head 7 in the width direction B, the recording device 1 ejects ink from the recording head 7 onto a medium supported by a tray 4 to form a desired image.

[0039] In the recording device 1 of this embodiment, the set position P1 for the medium on the tray 4 is on the front side, which is the lower left direction in FIG. 1. Then, the tray 4 with the medium set thereon is moved in direction A1 of the movement direction A to recording start position P2, which is on the back side, which is the upper right direction in FIG. 1, and then recording is performed while the tray 4 is moved in direction A2 of the movement direction A. In FIG. 3, the solid line represents the state in which the tray 4 is at set position P1, and the dashed line represents the state in which the tray 4 is at recording start position P2. Inside the main body of the recording device 1, the detection position for the medium by the medium detection unit 40 is on the side of set position P1, in direction A2, and there is an opposing position facing the recording head 7, which reciprocates in the width direction B, on the side of the medium detection unit 40, in direction A1, which is the side of recording start position P2.

[0040] The recording device 1 of this embodiment includes a recording head 7 that records an image while moving back and forth in the width direction B. However, the recording device may also include a so-called line head, which has multiple nozzles that eject ink in a direction intersecting the direction of medium movement. Here, a "line head" refers to a recording head used in a recording device that forms an image by moving the recording head or medium relative to itself, where the nozzle area formed in the direction intersecting the direction of medium movement is arranged to cover the entire intersecting direction. Note that the nozzle area of ​​the line head in the intersecting direction does not necessarily have to cover the intersecting direction for all media supported by the recording device. Furthermore, while the recording head 7 of this embodiment is a recording unit that can record an image by ejecting ink onto a medium, the recording unit is not limited to this type of recording unit. For example, a transfer-type recording unit that transfers a colorant onto a medium for recording may also be used.

[0041] Next, the electrical configuration of the recording device 1 of this embodiment will be described with reference to Fig. 4. Fig. 4 is a block diagram of the recording device 1. The recording device 1 is equipped with a control unit 25 that controls various operations. The control unit 25 is provided with a CPU 26 that is responsible for overall control of the recording device 1. The CPU 26 is connected via a system bus 27 to a ROM 28 that stores various control programs executed by the CPU 26, and to a RAM 29 that can temporarily store data.

[0042] The CPU 26 is also connected to a head drive unit 30 for driving the recording head 7 via a system bus 27. The CPU 26 is also connected to a motor drive unit 31 via the system bus 27. The motor drive unit 31 is then connected to a carriage motor 32 for moving the carriage 6 on which the recording head 7 is provided in the width direction B, and a transport motor 33 for transporting the medium, i.e., for moving the tray 4 in the movement direction A.

[0043] The CPU 26 is also connected to an operation panel 41, a medium detection unit 40, a tray position detection unit 11, and a buzzer 42, all of which will be described later, via a system bus 27. The CPU 26 is also connected to an input / output unit 35. The input / output unit 35 is then connected to a PC 36. Generally, the medium detection unit 40 and the tray position detection unit 11 are expensive, and not many of them are provided.

[0044] The control unit 25 of this embodiment, configured as described above, controls the driving of each component, such as the recording head 7, carriage 6, and tray 4, in association with the recording operation. It also determines the position of the stage 5 in the facing direction C based on the detection result of the tray position detection unit 11, and, based on the determination result, can cause each component to execute a corresponding operation, such as adjusting the timing of ink ejection from the recording head 7 according to the distance between the recording head 7 and the medium. Furthermore, it can display various information, such as the detection result of the medium detection unit 40, on the display unit 41a of the operation panel 41, and prompt the user to input desired instructions via the buttons 41b, etc.

[0045] Here, the tray position detection unit 11, which is a main part of the recording device 1 of this embodiment, will be described with reference to FIGS. 5 to 9. FIG. 5 is a schematic side view of the medium support unit 2 as a support unit. As shown in FIG. 5, the recording device 1 includes the tray position detection unit 11 capable of detecting an object located within its detection range, and a detection target unit 12 located within the detection range of the tray position detection unit 11. In this embodiment, the tray position detection unit 11 and the detection target unit 12 are each attached to the medium support unit 2. FIGS. 6 and 7 are schematic perspective views showing the periphery of the tray position detection unit 11 and the detection target unit 12. Note that FIGS. 6 and 7 are views viewed from different angles. FIG. 8 is a schematic perspective view showing the periphery of the tray position detection unit 11. As shown in FIGS. 6 and 8, the tray position detection unit 11 of this embodiment includes a detection unit 11A and a detection unit 11B. That is, the tray position detection units 11 are provided on one side and the other side of the center of the medium support unit 2 in the width direction B. Furthermore, as shown in Figures 6 and 7, the detectable portion 12 in this embodiment has a detectable portion 12A provided at a position corresponding to the detecting portion 11A, and a detectable portion 12B provided at a position corresponding to the detecting portion 11B.

[0046] 6, 7, and 8, the tray position detection unit 11 of this embodiment is provided on the arm unit 10 of the medium support unit 2. As shown in FIG. 8 and other figures, the tray position detection unit 11 of this embodiment, both detection unit 11A and detection unit 11B, include an optical sensor S and a holder 13 that holds the optical sensor S. The detection unit 11A includes optical sensors SA and SB as the optical sensors S, and the detection unit 11B includes optical sensors SC and SD as the optical sensors S.

[0047] FIG. 9 is a schematic perspective view of the tray position detection unit 11. As shown in FIG. 9, each optical sensor S includes a light-emitting unit Se and a light-receiving unit Sr. While FIG. 9 shows the detection unit 11A as an example, the detection unit 11B has a similar configuration. In this case, the light-emitting unit Se is configured to irradiate light toward the light-receiving unit Sr. The light-receiving unit Sr is configured to receive the light irradiated from the light-emitting unit Se. Each optical sensor S is configured to detect whether the light irradiated from the light-emitting unit Se toward the light-receiving unit Sr in the space G between the light-emitting unit Se and the light-receiving unit Sr is blocked by the detection target 12.

[0048] In this embodiment, both the detection target portion 12A and the detection target portion 12B have a generally U-shape, i.e., a generally C-shape, when viewed from the opposing direction C. The detection target portion 12A has a flat plate portion 12a provided at a position corresponding to the space G of the optical sensor SA and having a plurality of holes H formed therein, and a flat plate portion 12b provided at a position corresponding to the space G of the optical sensor SB and having a plurality of holes H formed therein. The detection target portion 12B has a flat plate portion 12c provided at a position corresponding to the space G of the optical sensor SC and having a plurality of holes H formed therein, and a flat plate portion 12d provided at a position corresponding to the space G of the optical sensor SD and having a plurality of holes H formed therein. Here, the areas of the flat plate portions 12a to 12d that correspond to the hole H correspond to areas that transmit light irradiated from the light-emitting portion Se toward the light-receiving portion Sr, and the areas of the flat plate portions 12a to 12d that do not have the hole H correspond to areas that block light irradiated from the light-emitting portion Se toward the light-receiving portion Sr. Therefore, the detected portion 12 is configured to be able to indicate its own position in the facing direction C based on the presence or absence of the hole H.

[0049] Because the detection target portion 12 has such a configuration, the tray position detection portion 11 of this embodiment can detect the position of the detection target portion 12 in the facing direction C. This allows the control portion 25 to grasp the position of the tray 4 in the facing direction C from the detection result of the tray position detection portion 11.

[0050] An embodiment of a method for adjusting the height of the tray 4 (position in the facing direction C) (method for controlling the recording device) using the recording device 1 of this embodiment will be described below with reference to the flowcharts in FIGS. 10 and 11. Here, the flowcharts in FIGS. 10 and 11 will be described in comparison with the flowcharts in FIGS. 12 and 13, which serve as comparative examples of an example of a method for adjusting the height of the tray 4 that can also be performed in conventional recording devices. Note that in the method for adjusting the height of the tray 4, a first operation is performed followed by a second operation. The flowcharts in FIGS. 10 and 12 correspond to the first operation, and the flowcharts in FIGS. 11 and 13 correspond to the second operation.

[0051] Here, an overview of the method for adjusting the height of the tray 4 will be described. The purpose of adjusting the height of the tray 4 is to achieve a desired distance in the facing direction C between the media placed on the tray 4 and the recording head 7. Therefore, the tray 4 is adjusted to a position where the desired distance is achieved by gradually shifting the tray 4 from a lower position, where the distance is wider, to an upper position, where the distance is narrower. The reason for adjusting the position of the tray 4 by gradually shifting it from a lower position to an upper position is to minimize the possibility of a collision between the media placed on the tray 4 and the recording head 7. Note that in the method for adjusting the height of the tray 4 of this embodiment, the tray 4 is lowered two steps from a reference position, which is the height at which the media can be detected by the media detection unit 40, to achieve an appropriate distance in the facing direction C between the recording head 7 and the media. However, this method does not have to be adopted. Furthermore, the method for adjusting the height of the tray 4 of this embodiment involves performing a first operation, the main purpose of which is to adjust the height of the tray 4, and a second operation, the main purpose of which is to confirm whether the height of the tray 4 adjusted in the first operation is appropriate.

[0052] First, the first operation of the flowchart in FIG. 12 will be described as a comparative example. The first operation of the flowchart in FIG. 12 as a comparative example can be performed by the recording device 1 of this embodiment, and may also be performed by a conventional recording device. In the first operation of the method for adjusting the height of the tray 4 of the comparative example shown in FIG. 12, first, in step S310, the recommended height of the tray 4 is displayed on the display unit 41a. As shown in FIG. 8, the lever 9 is formed with a stepped protrusion placement portion 15, and information such as on which step of the protrusion placement portion 15 the protrusion 14 should be placed can be displayed on the display unit 41a. The user can perform step S310, for example, at the set position P1.

[0053] Next, in step S320, tray 4 is moved to recording start position P2. Then, in step S330, tray 4 is moved in direction A2 from recording start position P2 to set position P1 by medium conveying unit 3. Then, in step S340, control unit 25 checks whether medium detection unit 40 detects a medium during this movement. Note that in the first operation of the flowchart in FIG. 12, medium detection is performed while moving tray 4 in direction A2 from recording start position P2 to the set position P1 side, but medium detection may also be performed while moving tray 4 in direction A1 from set position P1 to the recording start position P2 side.

[0054] If, in step S340, the control unit 25 determines that the medium detection unit 40 did not detect a medium, the process proceeds to step S350, where the display unit 41a displays a message urging the user to change the tray 4 level, i.e., the placement position of the protrusion 14 relative to the protrusion placement unit 15, to a level one level higher (to raise the tray 4 by one level). After changing the placement position of the protrusion 14 to a level one level higher, the user returns to step S320 by pressing button 41b or the like to advance the phase, and steps S320 to S340 are repeated. On the other hand, if, in step S340, the control unit 25 determines that the medium detection unit 40 detected a medium, the process proceeds to step S360, where the control unit 25 determines whether this position adjustment of the tray 4 is a first provisional determination or a provisional determination after steps S320 to S340 have already been repeated several times. The determination as to whether or not this position adjustment of tray 4 is the first provisional determination can be made using the detection results of a detection means, such as tray position detection unit 11 of this embodiment, that detects the position of tray 4 in the facing direction C, or a detection means that detects the rotation of lever 9. Specifically, for example, if the medium detection of step S330 is started without detecting any change in the position of tray 4 in the facing direction C since the start of the first operation, it is determined to be the first adjustment, and in any other cases it is determined not to be the first adjustment.

[0055] If the control unit 25 determines in step S360 that this adjustment of the tray 4 position is the first provisional determination, the control unit 25 determines that the tray 4 position may be too high relative to the desired height, and proceeds to step S370, where it displays a message on the display unit 41a prompting the user to lower the tray 4. The user then advances the phase by pressing button 41b or the like, and the process returns to step S320. On the other hand, if the control unit 25 determines in step S350 that this adjustment of the tray 4 position is not the first provisional determination, the control unit 25 determines that the tray 4 position is at the desired height, and proceeds to step S380, where it displays a message on the display unit 41a prompting the user to lower the tray 4 by two levels (so that the placement position of the protrusion 14 relative to the protrusion placement portion 15 is two levels lower), and moves the tray 4 to the set position P1, thereby completing the first operation. Note that this assumes that the media detection unit 40 has a configuration in which lowering the tray 4 by two levels relative to the reference position results in an optimal spacing between the recording head 7 and the media in the facing direction C.

[0056] By executing these steps, steps S320 to S350 had to be repeated many times in the first operation of the flowchart in Fig. 12. Repeating steps S320 to S350 not only increased the user's workload, but also required the tray 4 to be moved back and forth from the set position P1 to the recording start position P2 many times, which resulted in a long time from the start to the end of the first operation.

[0057] Next, a description will be given of the second operation in the flowchart of Fig. 13 as a comparative example. Like the first operation in the flowchart of Fig. 12, the second operation in the flowchart of Fig. 13 as a comparative example can be performed by the recording device 1 of this embodiment and may also be performed by a conventional recording device.

[0058] 13, the second operation begins immediately after the first operation is completed. In the second operation of the flowchart in Fig. 13, first, in step S410, the control unit 25 checks whether the medium detection unit 40 detects the medium while the medium transport unit 3 moves the tray 4 in direction A1 from the set position P1 to the recording start position P2. This step S410 corresponds to the step of checking again whether the medium placed on the tray 4 does not come into contact with the recording head 7.

[0059] For this reason, in step S420 following step S410, control unit 25 determines whether or not a medium has been detected by medium detection unit 40, but normally it will determine that a medium has not been detected, and the second operation ends there. However, if control unit 25 determines in step S420 that a medium has been detected by medium detection unit 40, the process proceeds to step S430, where the tray is moved to the set position P1 side, and then in step S440 a message is displayed on display unit 41a urging the user to lower tray 4, the process returns to step S410, and steps S410 to S420 are repeated.

[0060] Next, the first operation of the flowchart of FIG. 10 of this embodiment will be described. In the first operation of the method for adjusting the height of tray 4 of this embodiment shown in FIG. 10, first, in step S110, the tray 4 with media set thereon is moved to a detectable position, which is a first position where at least a portion of the media placed on tray 4 overlaps the position where the media is detected by the media detection unit 40, as viewed from the facing direction C. In the first operation of the flowchart of FIG. 12, the height of tray 4 was adjusted at set position P1. On the other hand, in the first operation of the flowchart of FIG. 10 of this embodiment, the height of tray 4 is adjusted at a detectable position where at least a portion of the media placed on tray 4 is located at the position where the media is detected by the media detection unit 40.

[0061] Next, in step S120, the height of tray 4 is adjusted at the position where the medium is detected by medium detection unit 40, and the height of tray 4 is tentatively determined. This is performed, for example, by the user rotating lever 9 so that protrusion 14 is placed on the desired step of protrusion placement unit 15, which is determined based on the detection result of tray position detection unit 11 and displayed on display unit 41a, and then pressing button 41b or the like to proceed to the next step.

[0062] After the provisional determination of the height of tray 4 in step S120, a medium detection operation is performed in step S130. Specifically, the user sets a medium in tray 4, and the medium transport unit 3 moves tray 4 from set position P1 in direction A1 so that at least a portion of the medium placed on tray 4 is positioned at the first position, which is a detectable position for the medium detection unit 40, and the control unit 25 checks whether the medium is detected by the medium detection unit 40. If the medium is not detected in step S130, the process proceeds to steps S140 and S150, and then returns to step S120. In step S140, the buzzer 42 remains off, and in step S150, the display unit 41a displays a message urging the user to raise the tray 4. On the other hand, if the medium is detected in step S130, the buzzer 42 is turned on in step S160 to sound a buzzer sound, and the process proceeds to step S170. Then, in step S170, the control unit 25 determines whether this position adjustment of the tray 4 is the first provisional determination or whether it is a provisional determination after steps S120 to S150 have already been repeated several times. In this embodiment, the buzzer 42 is turned on when a medium is detected and turned off when a medium is not detected, but the reverse may also be true. Furthermore, upon completion of steps S150 and S160, a display may be displayed on the display unit 41a to confirm the completion, or the user may be prompted to input confirmation of the display by pressing button 41b.

[0063] If the control unit 25 determines in step S170 that this adjustment of the tray 4 position is the first provisional determination, the control unit 25 determines that the position of the tray 4 may be too high relative to the desired height, proceeds to step S180, causes the display unit 41a to display a message prompting the user to lower the tray 4, and the user presses button 41b or the like to advance the phase, returning to step S120. On the other hand, if the control unit 25 determines in step S170 that this adjustment of the tray 4 position is not the first provisional determination, the control unit 25 determines that the position of the tray 4 is at the desired height, proceeds to step S190, causes the display unit 41a to display a message prompting the user to lower the tray 4 by two levels, and ends the first operation. Note that this is also based on the premise that the medium detection unit 40 has a configuration in which lowering the tray 4 by two levels relative to the reference position results in an optimal gap between the recording head 7 and the medium in the facing direction C. The control unit 25 determines whether the position adjustment of the tray 4 is the first provisional decision or not based on the detection result of the tray position detection unit 11 detecting whether the position of the tray 4 in the facing direction C has changed since the start of the first operation.

[0064] 10, steps S120 to S150 may need to be repeated, as in the first operation of the flowchart of Fig. 12. However, because the height of the tray 4 can be continuously adjusted without moving the tray 4 from the detectable position, the user's effort is reduced and the process does not take a long time.

[0065] Next, the second operation of the flowchart in Fig. 11 of this embodiment will be described. For example, the second operation starts as soon as the user confirms that the first operation has been completed by pressing button 41b or the like. In the second operation of the flowchart in Fig. 11, first, in step S210, the tray 4 is moved in direction A1 by the medium transport unit 3 from the detectable position to the recording start position P2.

[0066] Next, in step S220, the control unit 25 checks whether the medium is detected by the medium detection unit 40 while moving the tray 4 toward the set position P1 (direction A2). This step S220 corresponds to a step of checking again whether the medium placed on the tray 4 will come into contact with the recording head 7.

[0067] For this reason, in step S230 following step S220, the control unit 25 determines whether or not a medium has been detected by the medium detection unit 40, but normally it will determine that a medium has not been detected, and the second operation will end there. However, if the control unit 25 determines in step S230 that a medium has been detected by the medium detection unit 40, the process proceeds to step S240, where a message urging the user to lower the tray 4 is displayed on the display unit 41a, and the user is asked to input a confirmation instruction, after which the process returns to step S210 and steps S210 to S230 are repeated.

[0068] In the above embodiment, the second operation in the flowchart of FIG. 11 was executed following the first operation in the flowchart of FIG. 10. However, it is also possible to execute the second operation in the flowchart of FIG. 13 following the first operation in the flowchart of FIG. 10. Furthermore, following the first operation in the flowchart of FIG. 10, the tray 4 may be temporarily returned to the set position P1, which is its initial position, and then medium detection may be performed while moving the tray 4 in the direction A1 from the set position P1 to the recording start position P2. That is, the second operation, which reconfirms whether the medium placed on the tray 4 does not come into contact with the recording head 7, may be performed while moving the tray 4 in the direction A1 from the detectable position to the recording start position P2, or may be performed while temporarily returning the tray 4 to the set position P1 and moving the tray 4 in the direction A1 from the set position P1 to the recording start position P2, or may be performed while moving the tray 4 in the direction A2 from the recording start position P2 to the set position P1.

[0069] The following provides additional information regarding each step of the first operation in the flowchart of Fig. 10 and the second operation in the flowchart of Fig. 11. As described above, the control method for a recording device of this embodiment is a control method for a recording device 1 that includes: a recording head 7 that records on a medium; a tray 4 that is adjustable in position in an opposing direction C as a first direction and that has a medium placed on it and is movable in a movement direction A as a second direction that intersects with the opposing direction C and includes a position facing the recording head 7 in the opposing direction C; a lever 9 that adjusts the position of the tray 4 in the opposing direction C; a medium transport unit 3 that moves the tray 4 in the movement direction A; a medium detection unit 40 that is capable of detecting whether a medium placed on the tray 4 is at a reference position in the opposing direction C at a detection position within the movement range of the tray 4 by the medium transport unit 3; a display unit 41a and button 41b that accepts input of instructions; and a display unit 41b that notifies information.

[0070] Then, in the first operation, in step S110, when adjusting the position of the tray 4 in the facing direction C, the tray 4 is moved by the medium conveying unit 3 to a detectable position (first position) so that at least a portion of the tray 4 is located at the detection position in accordance with instructions received by the display unit 41a and button 41b. Also, in step S130, the medium detection unit 40 is caused to detect whether the medium is at the reference position at the detectable position. Also, in steps S140 to S160, the buzzer 42 and display unit 41a serving as an alarm unit are caused to notify information based on the detection results of the medium detection unit 40.

[0071] Then, in the second operation, in step S220, after the first operation, in response to instructions from the user received via display unit 41a and button 41b, tray 4 is moved by medium conveying unit 3 so that the entire area of ​​tray 4 in movement direction A passes through the detection position, and medium detection unit 40 is caused to detect whether the medium is at the reference position while the medium is passing through the detection position. Also, in step S240, display unit 41a is caused to notify, based on the detection result of medium detection unit 40, that tray 4 will be lowered by one level.

[0072] As described above, in the control method for the recording device of this embodiment, in the first operation, the medium transport unit 3 moves the tray 4 to the first position, which is the detectable position, so that at least a portion of the tray 4 is located at the detection position, the medium detection unit 40 detects whether the medium is at the reference position at the detectable position, and the buzzer 42 and the display unit 41a notify information based on the detection result of the medium detection unit 40. In other words, the tray 4 is moved to the first position, and the height adjustment of the tray 4 can be completed at the first position. Therefore, by executing the control method for the recording device of this embodiment, the height adjustment of the tray 4 can be completed without having to move the tray 4 back and forth multiple times in the movement direction A, thereby reducing the burden on the user associated with adjusting the height of the tray 4.

[0073] From the perspective of the recording device, the recording device 1 of this embodiment is equipped with a control unit 25. The control unit 25 controls the control method of the recording device, so that the height adjustment of the tray 4 can be completed without moving the tray 4 back and forth multiple times in the movement direction A, thereby reducing the burden on the user associated with adjusting the height of the tray 4.

[0074] Furthermore, in step S150, if the medium detection unit 40 does not detect that the medium is at the reference position in the first operation, the control unit 25 causes the display unit 41a to display information urging the user to use the lever 9 to move the tray 4 upward (in a direction that moves the position of the tray 4 in the facing direction C closer to the recording head 7). Therefore, the user can easily move the tray 4 to the reference position by following the information displayed on the display unit 41a.

[0075] Here, when the medium detection unit 40 detects that the medium is in the reference position in step S130 of the first operation, the control unit 25 causes the buzzer 42, which is the notification unit, to notify the user in step S160 that the medium is in the reference position. This allows the user to properly recognize that the medium is in the reference position. Note that there are no particular limitations on the notification unit, and notification by the notification unit can be done in various ways, such as displaying on a monitor, emitting a buzzer sound, or turning on a light. In this embodiment, the display unit 41a and the buzzer 42 correspond to the notification unit.

[0076] Furthermore, if the medium detection unit does not detect that the medium is in the reference position in step S130 of the first operation, control unit 25 repeats detection by the medium detection unit in the first operation and notification by the notification unit until medium detection unit 40 detects that the medium is in the reference position in the first operation, as represented by repeating steps S120 to S150. However, if medium detection unit 40 detects that the medium is in the reference position in the initial first operation in step S170, control unit 25 causes display unit 41a to display, in step S190, information that the medium is in the reference position, information urging the user to use lever 9 to move downward (in a direction that moves the position of tray 4 in facing direction C away from recording head 7), and information urging the user to end the first operation. Here, the initial first operation means the operation of adjusting the position of the tray 4 in the opposing direction C using the lever 9 for the first time after starting the first operation, and in this embodiment, the control unit 25 determines whether the position of the tray 4 in the opposing direction C has changed since starting the first operation by detecting with the tray position detection unit 11.

[0077] In this way, by repeating detection by the medium detection unit and notification by the notification unit in the first operation until the medium detection unit 40 detects that the medium is in the reference position in the first operation, it is possible to reliably ensure that the medium is in the reference position. However, if the medium detection unit 40 detects that the medium is in the reference position in the initial first operation, there is a risk that the position of the tray 4 in the facing direction C is too close to the recording head 7. However, as described above, when the medium detection unit 40 detects that the medium is in the reference position in the initial first operation, the display unit 41a displays information that the medium is in the reference position, information prompting the user to move the medium downward using the lever 9, and information prompting the user to end the first operation. This prevents the user from mistakenly perceiving the position of the tray 4 in the facing direction C as appropriate when the position of the tray 4 in the facing direction C is too close to the recording head 7.

[0078] Furthermore, the control unit 25 can notify information prompting the user to end the first operation in step S190, end the first operation in response to the instruction to end the first operation received by the display unit 41a and the button 41b, and display information prompting the user to start the second operation on the display unit 41a. This allows the instruction to end the first operation to serve as an instruction to start the second operation, and the second operation can be started promptly after the first operation is completed. Note that in this embodiment, after the completion of step S190, i.e., after the completion of the first operation, the tray 4 is temporarily returned to the set position P1, which is the initial position; however, the second operation may be started after the completion of the first operation without returning the tray 4 to the initial position.

[0079] Furthermore, as described above, the recording device 1 of this embodiment is equipped with the tray position detection unit 11 that can detect the position of the tray 4 in the facing direction C. After the medium detection unit 40 detects that the medium is at the reference position in step S130 of the first operation, the control unit 25 can, in step S180, cause the display unit 41a to display information that prompts the user to adjust the position of the tray 4 using the lever 9 until the position of the tray 4 detected by the tray position detection unit 11 reaches a position that is the first distance downward from the reference position. Therefore, the recording device 1 of this embodiment can accurately adjust the position of the tray 4 in the facing direction C using the detection result of the tray position detection unit 11. Also, in step S190, it is possible to cause the display unit 41a to display information that prompts the user to adjust the position of the tray 4 using the lever 9 until the position of the tray 4 detected by the tray position detection unit 11 reaches a position that is two steps lower, i.e., the first distance.

[0080] Furthermore, when the medium detection unit 40 detects that the medium is at the reference position in step S220 of the second operation, the control unit 25 can, in step S240, cause the display unit 41a to display information indicating that the medium is at the reference position, and can also display information on the display unit 41a urging the user to stop the movement of the tray 4 by the medium transport unit 3 and move it downward using the lever 9, and information urging the user to resume the second operation after adjusting the position of the tray 4. Therefore, the recording device 1 of this embodiment can prevent the medium from being at the reference position in the second operation, i.e., the tray 4 and the recording head 7 being too close in the facing direction C, resulting in contact between the medium and the recording head 7 when the recording operation is performed. Furthermore, the distance between the tray 4 and the recording head 7 in the facing direction C can be set within an appropriate range. In this embodiment, a message indicating that the tray 4 should be lowered by one level is displayed in step S240, but a message indicating that the tray 4 should be lowered by multiple levels may also be displayed. In step S240, tray 4 is lowered at set position P1, but moving tray 4 to set position P1 may be done automatically or by the user inputting instructions via display unit 41a and button 41b.

[0081] Furthermore, when returning from step S240 to step S220, in response to an instruction to resume the second operation received via the display unit 41a and button 41b, the control unit 25 can temporarily move the stopped tray 4 to set position P1 or recording start position P2, which are positions where the second operation can be started from the beginning, using the medium transport unit 3, and resume the second operation. Therefore, when resuming the second operation, the recording device 1 of this embodiment can again perform medium detection in the second operation over the entire area in the movement direction A of the tray 4, and can particularly effectively suppress contact between the medium and the recording head 7.

[0082] Furthermore, when returning from step S240 to step S220, the control unit 25 can resume the second operation for the stopped tray 4 from the stopped position in the movement direction A, in response to the instruction to resume the second operation received via the display unit 41a and the button 41b. Therefore, the recording device 1 of this embodiment can reduce the time required to perform the second operation again.

[0083] Furthermore, in response to the instruction to resume the second operation received via the display unit 41a and button 41b in step S240, the control unit 25 can resume the second operation by using the medium transport unit 3 to slightly move the tray 4 in the opposite direction to the movement direction of the tray 4 at the time of restarted medium detection so that the area of ​​the tray 4 that is at the detection position in the movement direction A can be re-detected by the medium detection unit 40. Therefore, the recording device 1 of this embodiment can particularly effectively suppress contact between the medium and the recording head 7 because the position that caused the stop can be re-detected by the medium detection unit 40.

[0084] Furthermore, if the medium detection unit 40 does not detect that the medium is at the reference position in step S230 of the second operation, the control unit 25 can automatically move the tray 4 to the set position P1, which is the initial position, using the medium transport unit 3. Therefore, the recording device 1 of this embodiment can quickly start the next operation, such as a recording operation, when the position of the tray 4 in the facing direction C is appropriate. Meanwhile, the recording device 1 of this embodiment can stop the movement of the tray 4 during the second operation by inputting a stop command from the display unit 41a and button 41b. In such a case, the tray 4 can be moved to the initial position by inputting a command to move the tray 4 from the display unit 41a and button 41b. Note that, although the initial position is set to the set position P1 in this embodiment, the initial position is not limited to the set position and may be the recording start position P2 or another position.
