Description

[Technical Field]

[0001] The present invention relates to a medium ejection device that ejects a medium, and a recording device that includes the same. [Background technology]

[0002] In an ejection mechanism for ejecting media, an ejection space for ejecting media is provided in the housing of the device, and in consideration of the fact that the ejection space is dark and has poor visibility, a configuration is known in which a lamp is provided to illuminate the ejection space, as shown in Patent Document 1. According to the configuration described in Patent Document 1, when paper, an example of a medium, is discharged onto the tray, a lamp installed on the ceiling of the paper discharge space lights up. This makes it easy to check and remove the discharged paper, and also makes it easy to notice that paper has been discharged. Furthermore, Patent Document 2 discloses a configuration in which a discharge tray that receives discharged sheets moves between an expanded position and a stored position by the power of a motor.

[0009] The present invention will be briefly described below. The media ejection device of the first aspect comprises a media ejection section that ejects media and a media receiving tray that receives media ejected by the media ejection section, wherein the media receiving tray is switchable between a first state in which it is stored in a device main body that includes the media ejection section, and a second state in which it protrudes most from the device main body, and wherein a light-emitting section that emits light toward the media receiving tray is provided at a position downstream of the media ejection section in the media ejection direction, and a control section that controls the light-emitting section controls the light-emitting section according to the state or operation of the media receiving tray.

[0010] According to this aspect, the control unit that controls the light-emitting unit controls the light-emitting unit according to the state or operation of the media receiving tray, so that the status related to media ejection can be displayed with good visibility, thereby improving usability.

[0011] The second aspect is characterized in that, in the first aspect, the media receiving tray can be switched between the first state and the second state by the power of a motor controlled by the control unit, and the control unit causes the light-emitting unit to emit light when the media receiving tray in the first state is caused to protrude from the device main body.

[0012] According to this aspect, the control unit causes the light-emitting unit to emit light when the media receiving tray in the first state is protruded from the device main body, so that the user can understand that the state of the media receiving tray is changing by the light-emitting unit turning on. In this specification, the term "light emission" of the light-emitting portion is used to mean both lighting and blinking, and when simply referred to as "light emission," it means either lighting or blinking.

[0013] The third aspect is characterized in that, in the first aspect, the media receiving tray can be switched between the first state and the second state by the power of a motor controlled by the control unit, and the control unit changes the light-emitting state of the light-emitting unit if the media receiving tray does not switch to the target state even after driving the motor a predetermined amount.

[0014] According to this aspect, if the media receiving tray does not switch to the target state even after driving the motor a predetermined amount, the control unit changes the light-emitting state of the light-emitting unit, so that the user can recognize that an abnormality has occurred in the operation of the media receiving tray by the change in the light-emitting state of the light-emitting unit.

[0015] A fourth aspect is characterized in that in the second or third aspect, the control unit turns off the light-emitting unit when transitioning to a power-saving mode that reduces power consumption while the medium receiving tray is released from the first state and protruding from the device main body and the light-emitting unit is emitting light. According to this aspect, when the control unit transitions to a power-saving mode that reduces power consumption while the medium receiving tray is released from the first state and protruding from the device main body and the light-emitting unit is emitting light, the control unit turns off the light-emitting unit, thereby avoiding unnecessary power consumption.

[0016] The fifth aspect is characterized in that, in any of the second to fourth aspects, the control unit turns off the light-emitting unit when the power button is pressed while the medium receiving tray is released from the first state and protruding from the device main body and the light-emitting unit is emitting light. According to this aspect, when the power button is pressed while the medium receiving tray has released the first state and is protruding from the device body and the light-emitting unit is emitting light, the control unit turns off the light-emitting unit, so that the user can visually understand that the device is transitioning to a power-off state.

[0017] The recording device of the sixth aspect is characterized by comprising a recording unit that records on a medium, and the medium ejection device of any of the first to fifth aspects that ejects the medium on which recording has been performed by the recording unit. According to this aspect, in a recording device that records on a medium, the effects of any one of the first to fifth aspects described above can be obtained.

[0018] A recording device according to a seventh aspect comprises a recording unit that records on a medium, a medium discharge unit that discharges the medium on which recording has been performed by the recording unit, and a medium receiving tray that receives the medium discharged by the medium discharge unit, wherein the medium receiving tray is switchable between a first state in which it is stored in a device main body that includes the medium discharge unit, and a second state in which it protrudes most from the device main body, and a light-emitting unit that emits light toward the medium receiving tray is provided at a position downstream of the medium discharge unit in the media discharge direction, and the medium receiving tray is switchable between the first state and the second state by the power of a motor, and a control unit that controls the light-emitting unit causes the light-emitting unit to emit light in response to control of the motor to cause the medium receiving tray to protrude from the device main body when it receives an instruction to start recording when the medium receiving tray is in the first state and the light-emitting unit is off.

[0019] According to this aspect, when the control unit that controls the light-emitting unit receives an instruction to start recording while the media receiving tray is in the first state and the light-emitting unit is off, the control unit causes the light-emitting unit to emit light in response to control of the motor to protrude the media receiving tray from the device main body, so that the user can visually understand that the state of the media receiving tray is changing by the light emitted by the light-emitting unit, improving usability.

[0020] An eighth aspect comprises a recording unit that records on media, a media discharge unit that discharges media on which recording has been performed by the recording unit, and a media receiving tray that receives the media discharged by the media discharge unit, wherein the media receiving tray is switchable between a first state in which it is stored in a device main body that includes the media discharge unit, and a second state in which it protrudes furthest from the device main body, and a light-emitting unit that emits light toward the media receiving tray is provided at a position downstream of the media discharge unit in the media discharge direction, and a control unit that controls the light-emitting unit is capable of detecting whether the media receiving tray is in at least the first state, and when a command to start recording is received when the media receiving tray is in the first state and the light-emitting unit is off, the control unit does not emit light, and when a command to start recording is received when the media receiving tray is in a state other than the first state and the light-emitting unit is off, the control unit emits light.

[0021] According to this aspect, the control unit that controls the light-emitting unit is capable of detecting whether the media receiving tray is in at least the first state, and when an instruction to start recording is received when the media receiving tray is in the first state and the light-emitting unit is off, the control unit does not emit light, and when an instruction to start recording is received when the media receiving tray is in a state other than the first state and the light-emitting unit is off, the control unit emits light, so that the user can visually grasp the state of the media receiving tray from the state of the light-emitting unit, improving usability.

[0022] A ninth aspect is characterized in that, in the eighth aspect, the control unit causes the light-emitting unit to emit light when the medium receiving tray, which is in the first state, releases the first state. According to this aspect, the control unit causes the light-emitting unit to emit light when the media receiving tray, which is in the first state, releases the first state, so that the user can visually understand that the state of the media receiving tray has changed by the light emitted by the light-emitting unit.

[0023] The present invention will be specifically described below. In each figure, the direction along the X axis is the width direction of the device, which is the direction that intersects with the paper transport direction in which paper, an example of a medium, is transported, i.e., the paper width direction. The -X direction is to the right as seen by the user when the front of the device faces the user, and the +X direction is to the left as seen by the user. The direction along the Y axis is the depth direction of the device, the +Y direction is the direction from the back of the device to the front, and the -Y direction is the direction from the front of the device to the back. The +Y direction is the paper discharge direction from discharge port 17, through which paper that has been recorded is discharged. In this embodiment, of the side surfaces that make up the periphery of the device, the side surface on which front cover 4 is provided is the front surface of the device. The direction along the Z axis is the vertical direction, with the +Z direction being vertically upward and the -Z direction being vertically downward. In the following description, the direction in which the paper is fed may be referred to as "downstream," and the opposite direction may be referred to as "upstream."

[0024] 1 to 3, an inkjet printer 1, which is an example of a recording device, is a so-called multifunction device that includes a scanner unit 3 on top of a device main body 2. In the following, the inkjet printer 1 will be abbreviated as printer 1. The scanner unit 3 is rotatably provided with respect to the device body 2, and can be rotated between a closed state shown in Fig. 1 and an open state (not shown). The scanner unit 3 is equipped with a document cover 3a that opens and closes a document table 3b (see Fig. 4).

[0025] An upper cover 9 is provided on the rear side of the document cover 3a at the top of the device body 2. When the upper cover 9 is opened, it becomes possible to set paper in a hopper 12 (see FIG. 4). The device body 2 is provided with an operation panel 6 on the front of the device for performing various operation settings. In this embodiment, the operation panel 6 is configured as a touch panel. The operation panel 6 is also provided so as to be tiltable around a rotation axis (not shown).

[0026] A front cover 4 is provided at the bottom of the front of the device main body 2. The front cover 4 is rotatable relative to the paper feed tray 5 located at the bottom of the device main body 2, and by rotating it, it can be in a closed state as shown in Fig. 1 and in an open state as shown in Figs. When the front cover 4 is opened, an outlet 17 for discharging paper on which recording has been performed is exposed, and also a paper receiving tray 18 as a medium receiving tray for receiving paper discharged from the outlet 17 is exposed.

[0027] The paper receiving tray 18 can be switched between a first state in which it is stored inside the device main body 2 and a second state in which it protrudes most in the +Y direction as shown in Fig. 3. The state of the paper receiving tray 18 shown in Fig. 2 indicates a third state between the first and second states. The state of paper receiving tray 18 is switched by transmitting power from tray drive motor 60 (see FIG. 5) to paper receiving tray 18 via a rack and pinion mechanism (not shown). Whether paper receiving tray 18 is switched from the first state to the second state or the third state is determined by control unit 50 (see FIG. 5) based on paper size information included in the printing information.

[0028] The paper receiving tray 18 can be switched not only from the first state to the second state but also from the second state to the first state by the power of the tray drive motor 60 (see FIG. 5). However, the switching of the paper receiving tray 18 from the second state to the third state may be left to the user's operation, and the switching from the third state to the first state may be performed by the power of the tray drive motor 60. Alternatively, the switching of the paper receiving tray 18 from the second state to the first state may be entirely left to the user's operation.

[0029] In this embodiment, the paper receiving tray 18 can be in a third state in addition to the second state, and can receive paper in both the second state and the third state, but the third state may be omitted, i.e., the paper receiving tray 18 may only receive paper in the second state. Conversely, the paper receiving tray 18 may be capable of receiving paper in another state in addition to the second and third states.

[0030] In this embodiment, in the third state shown in Fig. 2, for example, A4 size paper can be received when the long side is discharged along the Y axis. In the second state shown in Fig. 3, for example, A3 size paper can be received when the long side is discharged along the Y axis.

[0031] In this embodiment, the paper receiving tray 18 is configured to include a first tray 18c, a second tray 18b, and a third tray 18a, as shown in FIG. When the paper receiving tray 18 switches from the storage state of FIG. 1, i.e., the first state, to the third state of FIG. 2, the first tray 18c, the second tray 18b, and the third tray 18a are displaced together in the +Y direction. 2 to the second state in Fig. 3, the second tray 18b and the third tray 18a are displaced in the +Y direction relative to the first tray 18c. When the paper receiving tray 18 is switched to the second state, as shown in Fig. 3, the second tray 18b is located in the +Y direction from the first tray 18c, and the third tray 18a is located in the +Y direction from the second tray 18b.

[0032] As described above, in this embodiment, the paper receiving tray 18 is configured as a multi-stage tray, but it can also be configured as a single tray. In this case, too, a rack can be formed on the tray along the Y-axis direction, and a pinion gear that meshes with this rack can be provided to configure a rack-and-pinion mechanism, which can be displaced in the Y-axis direction by the power of a motor. Even in such a configuration, it is possible to switch between a first state in which the tray is stored inside the device main body 2 and a second state in which the tray protrudes most from the device main body 2 in the +Y direction compared to the first state.

[0033] Next, the paper transport path of the printer 1 will be further described with reference to Figure 4. Paper stored in the paper feed tray 5 located at the bottom of the device main body 2 is fed in the -Y direction by a feed roller 10 driven by a feed motor 52 (see Figure 5). The symbol T1 indicates the feed path of paper fed from the paper feed tray 5. Furthermore, the paper sheets set in the hopper 12 come into contact with the feed roller 11 as the hopper 12 rises, and are fed downstream by the rotation of the feed roller 11, which is driven by a feed motor 52 (see FIG. 5). The symbol T2 indicates the feed path of the paper sheets sent out from the hopper 12.

[0034] Above the feed roller 10, there is provided a reversing roller 8 driven by a feed motor 52 (see Figure 5), and paper sent out from the paper feed tray 5 or hopper 12 receives a feeding force from the reversing roller 8 and is sent towards a pair of conveying rollers 13 located in the +Y direction relative to the reversing roller 8. The paper is then transported to an area facing the recording head 15, that is, a recording area, by a pair of transport rollers 13 driven by a transport motor 53 (see FIG. 5).

[0035] A recording head 15, which is an example of a recording unit, is provided on a carriage 14, and the carriage 14 reciprocates in the X-axis direction by the power of a carriage motor 51 (see FIG. 5). The recording head 15 ejects ink onto paper as the carriage 14 moves. Then, the paper on which the recording has been performed is discharged toward the paper receiving tray 18 by a pair of discharge rollers 16 driven by a transport motor 53 (see FIG. 5). The discharge roller pair 16 is an example of a paper discharge unit that discharges paper after recording. The discharge roller pair 16, the paper receiving tray 18, and a light-emitting unit 23 (see FIG. 5) described later constitute a paper discharge device 34, which is an example of a medium discharge device.

[0036] Next, the control system of the printer 1 will be described with reference to FIG. The control unit 50 performs various controls of the printer 1, including feeding, transporting, discharging, and recording of paper. Signals are input to the control unit 50 from the operation panel 6, and signals for displaying the display of the operation panel 6, particularly the user interface (hereinafter referred to as "UI"), are sent from the control unit 50 to the operation panel 6.

[0037] The control unit 50 controls the carriage motor 51, the feed motor 52, the transport motor 53, and the tray drive motor 60. In this embodiment, each motor is a DC motor. The control unit 50 also receives detection signals from the position detection unit 57, rotation detection unit 58, medium detection unit 59, and tray detection unit 61. The position detection unit 57 is a linear encoder and is a detection unit for detecting the position in the X-axis direction of the carriage 14. The rotation detection unit 58 is a rotary encoder and is a detection unit for detecting the amount of rotation and the rotation speed of the roller driven by the transport motor 53.

[0038] The medium detection unit 59 is provided near the upstream side of the transport roller pair 13 and detects the passage of the leading and trailing edges of the paper. The medium detection unit 59 can be configured with a contact or non-contact sensor. Based on the detection information from the medium detection unit 59, the control unit 50 can determine whether the paper has been fed correctly, specifically whether a non-feed has occurred.

[0039] In this embodiment, the tray detection unit 61 is a detection means for detecting that the paper receiving tray 18 has switched to the third state shown in Fig. 2, and can be configured with, for example, a contact sensor. Note that the control unit 50 can detect that the paper receiving tray 18 has switched to the first state and can also detect that it has switched to the second state by detecting the drive direction and an increase in the drive current value of the tray drive motor 60. However, it goes without saying that a sensor for detecting the first state and a sensor for detecting the second state may be provided separately. The tray drive motor 60 is provided with a rotary encoder (not shown), and the control unit 50 can determine the direction and amount of rotation of the tray drive motor 60 based on the signal output from this rotary encoder.

[0040] The control unit 50 includes a CPU 54, a flash ROM 55, and a RAM 56. The CPU 54 performs various arithmetic processes in accordance with programs stored in the flash ROM 55, and controls the overall operation of the printer 1. A program for controlling the light-emitting unit 23, which will be described later, is also stored in the flash ROM 55. The flash ROM 55 is a non-volatile memory that can be read and written. Various setting information entered by the user via the operation panel 6 is also stored in the flash ROM 55. Various information is temporarily stored in the RAM 56, which is an example of a storage means. The control unit 50 also has an interface 62 through which communication with an external computer 90 is possible.

[0041] Next, a further description will be given of the discharge port 17. The discharge port 17 is a discharge position in the Y-axis direction from which the paper on which the recording head 15 has performed recording is discharged. The upper edge of the discharge opening 17 is formed with a facing portion 20 that faces the paper receiving tray 18 and the recording surface of the paper on which recording has been performed, as shown in FIGS.

[0042] 6 to 8, the facing portion 20 is configured to include an optical member 21. The optical member 21 is attached to the frame 30 so as to be located at the center of the area through which the paper passes in the X-axis direction, i.e., the paper width direction. In other words, the center position of the paper to be discharged in the paper width direction and the center position of the optical member 21 in the X-axis direction roughly coincide with each other.

[0043] The optical member 21 is made of a light-transmitting material and functions as a lens. In this embodiment, the optical member 21 is made of a colorless and transparent resin material, and the facing surface 21a that faces the recording surface of the paper is formed like frosted glass.

[0044] A light-emitting unit 23 is provided in the +Z direction relative to the optical member 21. In this embodiment, the light-emitting unit 23 is configured with a white LED. In this embodiment, two light-emitting units 23 are provided on the substrate 24 with a gap between them in the X-axis direction, i.e., the paper width direction. The two light-emitting units 23 are arranged symmetrically with respect to the center position of the optical member 21 in the X-axis direction, i.e., the paper width direction.

[0045] The light-emitting unit 23 emits light toward the optical member 21 in the direction indicated by the arrow Q in Figures 7 and 8. In other words, the optical member 21 is located at a position where the light emitted from the light-emitting unit 23 is incident. In Figures 7 and 8, the symbol P indicates the paper being ejected. The optical member 21 emits the incident light in a direction toward the recording surface of the paper P. The visible light emitted from the optical member 21 toward the recording surface of the paper P spreads in the paper width direction as shown in Figure 7, and also spreads in the paper transport direction as shown in Figure 8.

[0046] 6 and 8, reflective sheets 27 are provided upstream and downstream in the paper transport direction with respect to the optical path of the light emitted from the light-emitting unit 23. In other words, a pair of reflective sheets 27 are provided so as to sandwich the optical path of the light emitted from the light-emitting unit 23. The reflective sheet 27 extends from the position of the light-emitting unit 23 to the position of the upper surface of the optical member 21 in the Z-axis direction. The reflective sheet 27 also covers almost the entire area of ​​the optical member 21 in the X-axis direction. The reflective sheet 27 can be made of, for example, a white sheet material.

[0047] In addition, a shading sheet 28 is provided between the front panel 19 and the reflective sheet 27 on the side closer to the front panel 19. In this embodiment, the sizes of the shading sheet 28 in the X-axis direction and the Z-axis direction are the same as those of the reflective sheet 27. The shading sheet 28 can be made of, for example, a black sheet material.

[0048] 7 and 8 show a case where the paper receiving tray 18 is in the third state shown in Fig. 2 and an A4 size paper sheet, for example, is discharged into the paper receiving tray 18 with its long side aligned with the paper transport direction. In Fig. 7 and 8, the symbol S indicates the illumination range of the light emitted from the optical member 21 toward the recording surface of the paper sheet P.

[0049] The light emitted from the light-emitting unit 23 and incident on the optical member 21 is diffused in the paper width direction inside the optical member 21 because the opposing surface 21a is formed in a ground glass shape, and is then emitted toward the recording surface of the paper. In this embodiment, the emission range is wide enough to cover the entire short side of an A4 size paper.

[0050] 7 and 8, the symbol H1 indicates the distance between the paper receiving tray 18 and the optical member 21 in the Z-axis direction, i.e., the direction perpendicular to the recording surface of the paper. The distance H1 can be set to, for example, 30 mm or less. This makes the distance between the recording surface of the paper P and the optical member 21 30 mm or less.

[0051] As explained above, the facing portion 20 that faces the recording surface of the paper at the discharge position where the paper on which recording has been performed by the recording head 15 is discharged is located at a position where the light emitted from the light emitting portion 23 is incident and is arranged opposite the recording surface of the paper, and is equipped with an optical element 21 that radiates the incident light at least in a direction toward the recording surface of the paper, so that the recording results can be seen quickly and clearly, that is, before recording is completed, and user needs can be appropriately met.

[0052] Furthermore, the illumination range of the recording surface of the paper by the optical member 21 has a width in the paper width direction that covers the entire recording surface of the first size paper, so that the recording results can be more appropriately viewed. Note that, although the first size paper is A4 size paper in this embodiment, it is of course not limited to this. If the first size paper is the largest size paper that can be transported, the entire width of all sizes of paper can be irradiated.

[0053] In addition, in this embodiment, the optical element 21 is a light-transmitting element whose opposing surface 21a, which faces the recording surface of the paper, is formed like frosted glass, so that the light emitted from the light-emitting unit 23 can be diffused over a wider area.

[0054] Furthermore, as a means for diffusing the light emitted from the light-emitting portion 23 over a wider area, instead of or in addition to making the opposing surface 21a like frosted glass, the optical element 21 may be formed from a light-transmitting material containing a light-diffusing agent. As the light diffusing agent, barium sulfate, calcium carbonate, silicon oxide, magnesium carbonate, aluminum hydroxide, titanium oxide, zinc oxide, synthetic silica, glass beads, etc. can be used. Furthermore, it goes without saying that the means for diffusing the light emitted from the light emitting portion 23 over a wider range is not limited to making the opposing surface 21a like frosted glass or using a diffusing agent.

[0055] In this embodiment, the distance between the recording surface of the paper and the optical member 21 in the direction perpendicular to the recording surface is set to 30 mm or less, so that the recording results can be clearly seen at the paper discharge position. If the amount of light reaching the recording surface is sufficient, the distance between the recording surface and the optical member 21 may be greater than 30 mm.

[0056] Furthermore, in this embodiment, a pair of reflective sheets 27 are provided to sandwich the optical path of the light emitted from the light emitting unit 23 to the optical member 21, thereby ensuring the amount of light irradiated onto the recording surface of the paper from the optical member 21. Note that if a sufficient amount of light can be ensured without using the reflective sheet 27, the reflective sheet 27 may be omitted.

[0057] Furthermore, in this embodiment, a light-shielding sheet 28 is provided between the front panel 19, which is a wall that forms the front surface of the device, and the reflective sheet 27 that is close to the front panel 19, and therefore it is possible to suppress leakage of light from the front panel 19 to the front of the device. Note that if the light-shielding rate of the front panel 19 is high and it is difficult to visually recognize leakage of light to the outside of the device via the front panel 19, the light-shielding sheet 28 may be omitted.

[0058] Next, the control of the light-emitting unit 23 by the control unit 50 (FIG. 5) will be described. When recording on paper and when discharging the recorded paper, the control unit 50 causes the light emitting unit 23 to emit light at least from the time when the leading edge of the paper reaches the position facing the facing unit 20 until the trailing edge of the paper passes the position facing the facing unit 20. In other words, the recording surface of the paper is irradiated from the leading edge to the trailing edge of the paper. This is the most basic light emission of the light emitting unit 23. The light emitting unit 23 can emit light either in a lit state or a blinking state, and in this embodiment, the light emission is lit from the time when the leading edge of the paper reaches the position facing the facing unit 20 until the trailing edge of the paper passes the position facing the facing unit 20.

[0059] Based on the light emission of the light-emitting unit 23 described above, the control unit 50 controls the lighting and extinguishing of the light-emitting unit 23 as described below. Fig. 10 shows the flow of control of the light-emitting unit 23 by the control unit 50. When the control unit 50 receives a recording start instruction (Yes in step S101), it determines whether it is time to switch the light-emitting state of the light-emitting unit 23 (step S102).

[0060] When the control unit 50 determines that it is time to switch the light-emitting state of the light-emitting unit 23 (Yes in step S102), it switches (step S103) the light-emitting state of the light-emitting unit 23. Note that switching the light-emitting state of the light-emitting unit 23 includes switching between the off state, on state, and blinking state of the light-emitting unit 23, and maintaining each state. Then, it is determined whether the trailing edge of the paper has passed the position of light-emitting unit 23 (step S104). More specifically, the affirmative condition of step S104 is satisfied when either the trailing edge of the paper has passed the position facing opposing unit 20, or a predetermined time has passed since the trailing edge of the paper has passed the position facing opposing unit 20, or a predetermined time has passed since the recording operation on the paper has been completed, or a predetermined time has passed since the paper ejection operation has been completed. Then, when the trailing edge of the paper has passed the position of light-emitting unit 23 (Yes in step S104), it is determined whether it is time to turn off the light (step S105). Steps S102 to S104 are repeatedly executed until the trailing edge of the paper has passed the position of light-emitting unit 23 (No in step S104). Thereafter, when the control unit 50 determines that it is time to turn off the light (Yes in step S105), it turns off the light emitting unit 23 (step S106).

[0061] Steps S102 and S103 will be described in detail below. In this embodiment, the light emitting state of the light emitting unit 23 is switched in steps S102 and S103 in accordance with the operation of the paper receiving tray 18. In this embodiment, the switching of the light-emitting state of the light-emitting unit 23 in steps S102 and S103 employs the following (1) and (2), and when either (1) or (2) applies, the light-emitting state of the light-emitting unit 23 is switched. Of course, it is also possible to employ only either (1) or (2) below.

[0062] (1) When the paper receiving tray 18 in the first state is protruded from the device main body 2, the affirmative condition of step S102 is satisfied, and the process proceeds to step S103. That is, the light-emitting unit 23 is controlled in accordance with the operation of the paper receiving tray 18. Note that when the paper receiving tray 18 is in the first state, the light-emitting unit 23 is normally in an off state. More specifically, the affirmative condition of step S102 is considered to be satisfied simultaneously with the start of driving of the tray drive motor 60 (see FIG. 5), or at a timing around that time, and the process proceeds to step S103. In other words, the light-emitting unit 23 is caused to emit light in response to control of the tray drive motor 60 to project the paper receiving tray 18 from the device main body 2. In this case, the light-emitting unit 23 may emit light either in a steady state or a flashing state in step S103. In this way, when the control unit 50 receives an instruction to start recording while the paper receiving tray 18 is in the first state and the light-emitting unit 23 is off, it causes the light-emitting unit 23 to emit light in response to control of the tray drive motor 60 to protrude the paper receiving tray 18 from the device main body 2. The user can visually recognize that the state of the paper receiving tray 18 has been switched by the light emitted from the light emitting section 23 in this manner.

[0063] (2) If the paper receiving tray 18 does not switch to the target state even after the tray drive motor 60 (see FIG. 5) is driven a predetermined amount, the affirmative condition of step S102 is deemed to be satisfied, and the process proceeds to step S103. That is, the light-emitting unit 23 is controlled in accordance with the operation of the paper receiving tray 18. Then, in step S103, the light-emitting state of the light-emitting unit 23 is switched. As an example, the light-emitting unit 23 is made to blink. An example of the target state of paper receiving tray 18 is the third state in Fig. 2. More specifically, if there is no change in the detection signal of tray detection unit 61 (see Fig. 5) even when tray drive motor 60 is driven by the first drive amount, control unit 50 determines that the affirmative condition of step S102 is met, and proceeds to step S103 to flash light-emitting unit 23. The first drive amount is an amount obtained by adding a certain margin to the theoretical drive amount of tray drive motor 60 required to switch paper receiving tray 18 from the first state to the third state. This allows the user to visually recognize that an abnormality has occurred in the operation of the paper receiving tray 18 by the flashing of the light emitting portion 23. For example, if an obstacle is present in the operating area of ​​the paper receiving tray 18 and the paper receiving tray 18 comes into contact with the obstacle, causing an abnormality, the user removes the obstacle and then performs an error reset operation via the operation panel 6. When such an error reset operation is performed, the control unit 50 can resume control of the tray drive motor 60. It is preferable that the control unit 50 changes the light-emitting state of the light-emitting unit 23 from flashing to off when the error clearing operation is performed, and changes it from off to on when control of the tray drive motor 60 is resumed. This allows the user to visually understand that the abnormal state has been resolved.

[0064] In this embodiment, as described above, when a recording execution instruction is received and paper receiving tray 18 in the first state is caused to protrude from device main body 2, light-emitting unit 23 is caused to emit light. However, for example, if an operation button for switching the state of paper receiving tray 18 is provided on the UI of operation panel 6, and paper receiving tray 18 is switched from the first state to the second state or the third state at the user's discretion, control from step S102 onwards may be performed regardless of whether a recording execution instruction is received.

[0065] Next, step S105 will be described in detail. In this embodiment, the turning off of light-emitting unit 23 in steps S105 and S106 is not basically based on the state or operation of paper receiving tray 18, but it goes without saying that it may be based on the state or operation of paper receiving tray 18. In this embodiment, the turning off of the light-emitting unit 23 in steps S105 and S106 can be performed using any of the following methods (3) to (7). Of course, more than one of the following methods (3) to (7) may be used, or all of them may be used.

[0066] (3) When the rear end of the paper leaves the position facing the facing unit 20, or after a predetermined time has elapsed since the rear end of the paper leaves the position facing the facing unit 20, or after a predetermined time has elapsed since the recording operation on the paper has been completed, or after a predetermined time has elapsed since the paper ejection operation has been completed, the affirmative condition of step S105 is satisfied, and the light-emitting unit 23 is turned off in step S106. By turning off the light-emitting unit 23 in this manner, unnecessary power consumption can be reduced. Note that when the light-emitting unit 23 is turned off based on the recording operation on the paper or the ejection operation, it is preferable that the light be controlled so that light is irradiated at least from the leading edge to the trailing edge of the ejected paper, as described above.

[0067] (4) In the case where the UI of the operation panel 6 is provided with an operation button for switching the state of the paper receiving tray 18, and the user instructs the paper receiving tray 18 to be stored via the operation panel 6, the affirmative condition of step S105 is deemed to be satisfied, and the light-emitting unit 23 is turned off in step S106.

[0068] (5) When the mode shifts to a power saving mode in which power consumption is reduced while the light emitting unit 23 is emitting light, the affirmative condition of step S105 is satisfied, and the light emitting unit 23 is turned off in step S106. When switching to the power saving mode, if the paper receiving tray 18 is in a state other than the first state, it may be switched to the first state. In this case, the timing for turning off the light-emitting unit 23 may be, for example, simultaneously with the start of driving the tray drive motor 60 (see FIG. 5), or before or after that, or when the tray drive motor 60 stops driving, or before or after that. In this case, the light-emitting unit 23 is controlled in accordance with the operation of the paper receiving tray 18. As a result, unnecessary power consumption can be reduced.

[0069] (6) When the power button 49 (see FIGS. 1 to 3) is pressed while the light emitting unit 23 is emitting light, the affirmative condition of step S105 is satisfied, and the light emitting unit 23 is turned off in step S106. When the device transitions to the power-off state, if the paper receiving tray 18 is in a state other than the first state, it may be switched to the first state. In this case, the timing for turning off the light-emitting unit 23 can be, for example, simultaneously with the start of driving the tray drive motor 60 (see FIG. 5), or before or after that, or when the tray drive motor 60 stops driving, or before or after that. In this case, the light-emitting unit 23 is controlled in accordance with the operation of the paper receiving tray 18. As a result, the user can visually understand that the device has correctly transitioned to the power-off state.

[0070] (7) If an error occurs after the start of the recording operation, the affirmative condition of step S105 is deemed to be satisfied, and the light-emitting unit 23 is turned off in step S106. Errors include paper jams and running out of ink. By turning off the light-emitting unit 23 in this manner, unnecessary power consumption can be reduced. Note that it is preferable to turn on the light-emitting unit 23 again when the error is resolved.

[0071] In addition, in a configuration in which the paper receiving tray 18 is not motor-driven but can only be switched by user operation, and in which a means for detecting whether the paper receiving tray 18 is in at least the first state is provided, the light-emitting unit 23 may be controlled as follows. That is, when the control unit 50 receives a recording command while the paper receiving tray 18 is in the first state and the light-emitting unit 23 is off, the control unit 50 does not cause the light-emitting unit 23 to emit light and maintains the off state. That is, the timing of receiving the recording command is used as the timing for controlling the light-emitting state of the light-emitting unit 23, and the control unit 50 controls the light-emitting unit 23 according to the state of the paper receiving tray 18. By controlling the light-emitting unit 23 in this way, the user can determine that it is time to switch the state of the paper receiving tray 18. In this case, it is preferable that the control unit 50 suspends the start of the recording operation until the paper receiving tray 18 is released from the first state. Furthermore, when the control unit 50 receives a recording instruction while the paper receiving tray 18 is in a state other than the first state and the light-emitting unit 23 is off, it causes the light-emitting unit 23 to emit light. In this case, the timing of receiving the recording instruction is also used as the timing for controlling the light-emitting state of the light-emitting unit 23, and the light-emitting unit 23 is controlled according to the state of the paper receiving tray 18. In this case, the light-emitting unit 23 is turned on. By controlling the light-emitting unit 23 in this manner, the user can know that recording is possible.

[0072] Furthermore, in the case where the state of the paper receiving tray 18 is not motor-driven but can be switched only by user operation as described above, and the control unit 50 is equipped with a means for detecting whether the paper receiving tray 18 is in the first state, the control unit 50 may cause the light-emitting unit 23 to emit light when the paper receiving tray 18 in the first state is released from the first state. That is, the control unit 50 controls the light-emitting unit 23 in accordance with the operation of the paper receiving tray 18. In this case, the light-emitting unit 23 emits light in a lit state. By controlling the light-emitting unit 23 in this manner, the user can know that the state of the paper receiving tray 18 has been switched and that it is now ready for recording.

[0073] Furthermore, in the case where the state of paper receiving tray 18 can be switched only by user operation and not by motor drive as described above, and where control unit 50 is equipped with a means for detecting whether paper receiving tray 18 is in the first state, control unit 50 may turn off light-emitting unit 23 when paper receiving tray 18 is switched to the first state by user operation from a state in which light-emitting unit 23 is emitting light when paper receiving tray 18 is in a state other than the first state. In other words, control unit 50 controls light-emitting unit 23 in accordance with the operation of paper receiving tray 18. Controlling light-emitting unit 23 in this manner can reduce unnecessary power consumption.

[0074] As described above, the control unit 50 that controls the light-emitting unit 23 controls the light-emitting unit 23 based on the state or operation of the paper receiving tray 18, so that the status related to paper discharge can be displayed with good visibility, thereby improving usability. For example, when paper receiving tray 18 switches from the first state to the second state or the third state, that is, when it protrudes from device main body 2, the user can be notified of this operation. The protruding operation of paper receiving tray 18 is difficult to see, particularly in dark environments, but the light emitted by light-emitting section 23 makes it possible to grasp the operation of paper receiving tray 18 even in dark environments. As a result, for example, if there is an obstacle in the operating area of ​​paper receiving tray 18, it is possible to prevent paper receiving tray 18 from colliding with the obstacle. Controlling the light-emitting unit 23 according to the state of the paper receiving tray 18 means that the state of the paper receiving tray 18 is referenced when controlling the light-emitting unit 23. Controlling the light-emitting unit 23 according to the operation of the paper receiving tray 18 means that the control of the light-emitting unit 23 is associated with the operation of the paper receiving tray 18. The operation of the paper receiving tray 18 includes operation when powered by the tray drive motor 60 and operation when moved by the user. Control of the light emitting unit 23 also includes switching between the off state, on state, and flashing state of the light emitting unit 23, as described above, and maintaining each state.

[0075] Furthermore, the light emitting state of the light emitting unit 23 can be switched by adopting any one, a plurality, or all of the following (8) to (10). (8) A means for detecting whether the front cover 4 is open or closed is provided, and when it is detected that the front cover 4 is open, the light emitting unit 23 is illuminated. This is because when the front cover 4 is opened, the paper receiving tray 18 is switched from the first state to the third state or the second state, and there is a possibility that paper will be discharged. Note that this control can be substituted for the control (1) described above, for example. (9) A means for detecting the position of the operation panel 6 is provided, and when it is detected that the operation panel 6 has been tilted upward from the fully closed state shown in Figures 1 to 3, the light emitting unit 23 is made to emit light. This is because when the operation panel 6 is tilted upward, the paper receiving tray 18 may be switched from the first state to the third state or the second state, causing paper to be ejected. Note that this control can be substituted for the control (1) above, for example. (10) If the control unit 50 can execute a silent mode that suppresses noise by executing paper feeding operations and recording operations at a slow speed, the light-emitting unit 23 is illuminated when this silent mode is selected. In silent mode, the paper transport speed is slowed, and by illuminating the light-emitting unit 23 in such a case, the recording results can be checked more reliably over time. Note that this control can be substituted for the control (1) described above, for example.

[0076] The timing of turning off the lights in step S105 can be set to any one of the following (11) to (14). Of course, more than one of the following (11) to (14) may be adopted, or all of them may be adopted. (11) A means for detecting the presence or absence of paper on the paper receiving tray 18 is provided, and the light emitting unit 23 is turned off when paper is removed from the paper receiving tray 18. This reduces unnecessary power consumption. Note that this control can be substituted for the control (3) described above, for example. (12) A means for detecting whether the front cover 4 is open or closed is provided, and when it is detected that the front cover 4 is closed, the light emitting unit 23 is turned off. This is because when the front cover 4 is closed, paper is not discharged to the paper receiving tray 18. This control can be substituted for the control (3) described above, for example.

[0077] (13) A means for detecting the position of the operation panel 6 is provided, and when it is detected that the operation panel 6 has been tilted upward (not shown) to the fully closed position as shown in FIGS. 1 to 3, the light emitting unit 23 is turned off. This is because when the operation panel 6 is turned to the fully closed position, it is possible that the user has finished using the device. Note that this control can be substituted for the control (3) described above, for example. (14) A means for detecting the installation state of the paper feed tray 5 is provided, and the light-emitting unit 23 is turned off when the paper feed tray 5 is removed from the device body 2. When the paper feed tray 5 is removed from the device body 2, no recording operation is being performed on paper, so by turning off the light-emitting unit 23 in this state, unnecessary power consumption can be reduced. Note that when the paper feed tray 5 is re-installed, the light-emitting unit 23 may be returned to its original light-emitting state.

[0078] Furthermore, the light-emitting unit 23 may be controlled as follows. For example, when A4 size paper is discharged with its long side aligned in the Y-axis direction, the light-emitting unit 23 is lit, and when A3 size paper is discharged with its long side aligned in the Y-axis direction, the light-emitting unit 23 is blinking. This allows the user to visually distinguish whether the paper being discharged is A4 size or A3 size.

[0079] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the invention described in the claims, and it goes without saying that these modifications are also included in the scope of the present invention. For example, in the above embodiment, the paper discharge device 34, which is an example of a medium discharge device, is applied to the printer 1, which is an example of a recording device, but the present invention is not limited to this and can also be applied to, for example, an image reading device equipped with a reading unit that reads an image of a document. An example of an image reading device is a document scanner that reads an image of a document while transporting the document. [Explanation of symbols]
