The stacker and the panel are operated together when the sensor does not detect the medium on the stacker without returning the panel to its original position before moving it to the standby position. Returning Rutotomoni the panel based on the panel position before moving to the standby position while avoiding interference with the stacker for saving to the closed position.

  In the recording apparatus, the control unit performs the predetermined position when the power is off, when the power saving mode is entered, when the display unit of the panel is turned off, when the printing is started, or when the stacker open button is operated. Preferably, the panel is moved to a set position according to the one as described above, and the panel position before moving the panel is written in the storage unit.

  According to this configuration, the control unit is set as the predetermined position when the power is off, when the power saving mode is entered, when the display unit of the panel is turned off, when printing is started, or when the stacker open button is operated. Even when the panel is moved to the set position according to the one, when the predetermined time when the panel does not need to be held at the set position is reached, the panel is returned to the original panel position before moved to the set position. Thus, the user does not have to return the panel to the original panel position even if the control unit moves the panel to a predetermined position.

  In the recording apparatus, the control unit stores the panel as the predetermined time at any one of power on, return from power saving mode, print end, and stacker close button operation. It is preferable to move to the said panel position read from the part.

Move to the original panel position. Therefore, the user does not have to return to the original panel position even if the control unit moves the panel to a predetermined position.

  In the recording apparatus, the control unit waits for the panel to stop when the panel moves when the storage timing for writing the panel position to the storage unit comes, and waits for the position at which the panel stops. It is preferable to write in the storage unit.

  According to this configuration, when the storage timing for storing the panel position comes, if the panel is moving, the control unit waits until the panel stops and writes the position at which the panel stops in the storage unit. Therefore, the position where the user is moving the panel is not stored, and the panel position when the user stops the panel is stored. Therefore, after that, when it is not necessary to hold the panel at a predetermined position (set position), the panel can be returned to the panel position where the user has stopped the panel.

  In the recording apparatus, the control unit waits for the panel to stop if the panel moves at the time of transition to the power saving mode, and writes the panel position when the panel stops to the storage unit before entering the power saving mode. It is preferable to migrate.

  According to this configuration, the control unit waits until the panel stops if the panel moves at the time of transition to the power saving mode, and writes the panel position when the panel stops in the storage unit, and then the panel is in the power saving mode. After moving to a predetermined position (set position), the power saving mode is entered. Therefore, when returning from the power saving mode (predetermined time), the panel can be returned to the panel position when the user stops the panel.

  The above recording apparatus includes a stacker movable to a closed position stored in a housing of the recording apparatus and an open position for receiving a recorded medium, and the control unit sets the stacker to the open position at the start of printing. , Move the panel to the print standby position as the predetermined position, write the panel position before moving the panel to the storage unit, and read the panel from the storage unit when printing is completed. It is preferable to return to the said panel position.

  According to this configuration, at the start of printing, the stacker moves to the open position capable of receiving the recorded medium, and at this time, the panel is moved to the standby position at the time of printing as the predetermined position. The previous panel position is written to the storage unit. When printing is finished (at a predetermined time), the panel returns from the standby position as the predetermined position to the original panel position read from the storage unit before the start of printing. Therefore, the user does not have to return the panel to the original position before the start of printing after printing.

  In the recording apparatus, label printing can be performed on the disc in a state in which the tray capable of loading the disc is inserted into the housing from the panel side, and the control unit performs the label printing on the panel at the time of label printing. The panel is moved to a predetermined angle away from the insertion path of the tray, and the panel position before moving the panel to the predetermined angle is written in the storage unit, and when the removal of the tray is detected, the panel is stored in the storage unit It is preferable to return to the said panel position read from.

  According to this configuration, at the time of label printing, the control unit moves the panel as a predetermined position to a predetermined angle away from the insertion path of the tray, so that the user can easily insert the tray on which the disc is mounted. At this time, the panel position before moving the panel to a predetermined angle is written in the storage unit. The control unit detects that the tray has been taken out by the user after label printing is finished, and when it is a predetermined time when it is not necessary to hold the panel at a predetermined angle, the panel is brought to the original panel position read from the storage unit. return. If the panel is returned to its original position before taking out the tray, the panel will be in the way of taking out the tray.

Hereinafter, an embodiment in which a recording apparatus is embodied in a printer will be described with reference to the drawings.
As shown in FIG. 1, the printer 11 includes an apparatus main body 12 (hereinafter, also simply referred to as “main body 12”) as an example of a case having a thin substantially rectangular parallelepiped shape, and a front surface (right surface in FIG. 1) of the main body 12. And an operation panel 13 used for user's input operation. The operation panel 13 is pivotally attached about the upper end portion. The operation panel 13 includes a display unit 14 formed of a liquid crystal panel or the like and an operation unit 15 formed of a plurality of operation switches. The operation unit 15 includes a power switch 15a for turning on and off the power supply of the printer 11, and an operation switch 15b for selecting a desired item on the menu screen displayed on the display unit 14 and the like. Be

  As shown in FIG. 1, at a lower portion in the main body 12, a feeding cassette 16 capable of storing a plurality of sheets P as an example of a medium is inserted and attached in a removable state. A plurality of sheets P stored in the feeding cassette 16 are sequentially delivered one by one from the top by the pickup roller 17 (see FIG. 3), and the delivered sheets P are transported along a predetermined transport path It is transported in the direction Y.

  Further, in the main body 12, a carriage 18 is provided so as to be capable of reciprocating in the scanning direction X while being guided by a guide shaft 19 extending along the scanning direction X intersecting the transport direction Y. At the lower part of the carriage 18, a recording head 20 for ejecting ink droplets from the nozzles is attached. Printing is performed on the sheet Pd by ejecting ink droplets from the recording head 20 that reciprocates with the carriage 18 in the scanning direction X toward the surface of the sheet Pd that is intermittently conveyed in the conveyance direction. The printed sheet Pd is discharged from the discharge port exposed in a state in which the pivotable cover 21 disposed below the operation panel 13 is open, in the direction indicated by the white arrow in FIG. The printer 11 can also insert and print the sheet P manually from the insertion port exposed in a state in which the openable cover 22 provided at the rear of the main body 12 is opened.

  As shown in FIG. 2, the operation panel 13 is a movable type that opens and closes by pivoting about the front upper end of the main body 12, and between the closed position shown in FIG. 1 and the open position shown in FIG. It turns by electric motor. Further, as shown in FIG. 2, the main body 12 is provided with a stacker 23 (medium receiving portion) formed of a substantially square plate-like single sheet tray in a state capable of entering and exiting (displaying and retracting). The stacker 23 is motorized and has a closed position (retracted position) (for example, the state shown in FIG. 1) stored in the main body 12 and an open position (for example, the state shown in FIG. 2) which protrudes from the main body 12 by a predetermined amount. It is possible to move back and forth between. The operation panel 13 and the stacker 23 are driven by separate power sources. For example, at the time of power on operation, the operation panel 13 is pivoted forward from the closed position shown in FIG. 1 and is disposed at the open position of a predetermined posture angle easily viewable to the user as shown in FIG. The open position is, for example, about 45 degrees when the attitude angle when the operation panel 13 is in the closed position shown in FIG. 1 is 0 degree. The posture angle of the panel 13 at the open position is not limited to 45 degrees, and may be another posture angle between the closed position (0 degrees) and the full opening, and an angle within a range of, for example, 30 to 70 degrees is preferable. .

  Further, when printing is performed, for example, when a print job is received, the stacker 23 protrudes from the main body 12. The cover 21 is opened by being pushed by the protruding stacker 23. Then, when the stacker 23 reaches an open position slightly ahead of the fully open position, the stacker 23 decelerates and stops. Therefore, the stacker 23 is in the open state positioned within the range (open area) from the open position to the fully open position. The printed sheet Pd is discharged onto the stacker 23 in the open state. When printing is completed, the stacker 23 is stored in the main body 12 and placed in the closed position. Even when the stacker 23 retracts from the open state to the closed state, the operation panel 13 is held in the open state.

  Further, at the time of the power-off operation, the operation panel 13 and the stacker 23 in the open state shown in FIG. 2 perform the closing operation. That is, the closing operation from the open state of the operation panel 13 and the closing operation from the open state of the stacker 23 are performed at the same time. Further, on the display unit 14, an instruction button (icon button) capable of instructing an opening operation or a closing operation of the stacker 23 is displayed. If the display unit 14 is a touch panel, the opening and closing operations of the stacker 23 can be instructed by directly pressing the instruction button, and otherwise selecting and operating the instruction button by operating the operation switch 15 b. Note that the instruction button may be provided with an open button and a close button separately, or may be a close button when the stacker 23 is open and a single button that is an open button when the stacker 23 is closed. Good.

  In the printer 11 of the present embodiment, a path when the operation panel 13 rotates and a path when the stacker 23 moves in and out partially overlap in the middle. For this reason, there is a possibility that the operation panel 13 and the stacker 23 may collide in an overlapping portion of the path (hereinafter, also referred to as an “interference area”) depending on their positions and the timing of opening and closing. For example, when the closing operation of the stacker 23 and the closing operation of the operation panel 13 are simultaneously performed, the operation panel 13 is closed earlier, so that the both collide with each other. Therefore, in the present embodiment, when the operation panel 13 and the stacker 23 are opened together or closed together, control for adjusting the operation timing of the both is adopted. Details of this control will be described later. In the following description, the operation panel 13 may be simply referred to as "panel 13".

Next, the detailed configuration of the printer 11 will be described.
The components on the sheet conveyance path will be described below with reference to FIG. As shown in FIG. 3, the cassette feeding unit 25, the feeding unit 26, the medium conveying unit 27, the recording unit 28, and the feeding unit 29 are provided in the main body 12 along a path through which the sheet is fed and conveyed. It is equipped. The cassette feeding unit 25 is provided at a position facing the feeding cassette 16, the pickup roller 17 provided above the feeding cassette 16, and the leading end of the sheet P accommodated in the feeding cassette 16. And 30.

  The pickup roller 17 is provided at the tip of the swinging member 32 which can swing around the swinging shaft 31, and is rotated by the power transmitted from the transport motor 33 (see FIG. 8). The pickup roller 17 feeds the uppermost sheet P from the feeding cassette 16 to the feeding path by rotating in contact with the uppermost sheet of the sheets P stored in the feeding cassette 16. The uppermost sheet P to be sent out is separated from the next sheet P and subsequent sheets by the separation unit 30 during the delivery.

  As shown in FIG. 3, the feeding unit 26 provided on the downstream side of the feeding path of the separating unit 30 includes a feeding driving roller 34 driven by the feeding motor 33 and a pair of feeding driven rollers 35 and 36. Is equipped. The sheet P nipped between the feed drive roller 34 and the feed driven roller 36 is transported to the medium transport unit 27 while the transport direction is changed along the outer periphery of the feed drive roller 34. The medium transport unit 27 also includes a transport drive roller 37 similarly driven by the transport motor 33, and a transport driven roller 38 that is in pressure contact with the transport drive roller 37 and is driven to rotate. The sheet P is further transported downstream by the medium transport unit 27.

  As shown in FIG. 3, the recording unit 28 provided on the downstream side of the medium transport unit 27 includes a carriage 18, a recording head 20, and a support base 39 facing the recording head 20. The recording head 20 provided on the bottom of the carriage 18 in a state facing the conveyance path of the sheet P has a scanning direction X (FIG. 3) while the carriage 18 is guided by the guide shaft 19 by the power of the carriage motor 40 (see FIG. Then, in the process of reciprocating in the direction orthogonal to the paper surface, the ink droplet is jetted to the paper P and the image is printed on the paper P. At this time, the support base 39 supports the sheet P and defines the distance (gap) between the sheet P and the recording head 20.

  The feeding unit 29 provided on the downstream side of the support table 39 includes a first roller 41 driven by the conveyance motor 33 and a second roller 42 rotated in contact with the first roller 41. Then, the recording sheet P is fed by the feeding unit 29 in a state of being nipped by the first roller 41 and the second roller 42.

  The fed out recorded sheet P is a stacker disposed in the main body 12 from the closed position shown by the solid line in FIG. 3 and projecting forward when receiving a print job and arranged at the open position shown by the two-dot chain line in the figure. Ejected on top of 23 The stacker 23 has a projecting operation (opening operation) which slides along the Y direction and protrudes to the outside (forward) of the main body 12 and a retraction operation (closing operation which is slid along the Y direction and stored in the main body 12 Operation). The stacker 23 slides and protrudes outside the main body 12 at least at the time of printing.

  Further, the sheet P (indicated by a two-dot chain line in FIG. 3) manually fed from the feed port 43 exposed in a state where the cover 22 provided at the rear portion (right side in FIG. 3) of the main body 12 is opened The sheet is inserted between the drive roller 34 and the feed driven roller 36, and in this state, the conveyance motor 33 is driven to be conveyed by the medium conveyance unit 27 and the feeding unit 29. In the present embodiment, the feeding unit 26, the medium conveyance unit 27, and the feeding unit 29 constitute an example of the conveyance unit.

  The stacker 23 forms a slope guide surface 23a that inclines so that the tip end in the transport direction Y becomes higher toward the tip side, and a platform 23b that bulges upward while the width direction of the platform 23b (same as the scanning direction X And a pair of raised portions 23c that rise higher than the base portion 23b adjacent to both sides. Further, the stacker 23 is formed in a square plate shape (see FIG. 7) except a base portion 23d except for the tip end. Between the plate-like frame 44 disposed on the lower side of the support table 39 and the plate-like support plate portion 45 disposed on the lower side at a predetermined distance therefrom, the stacker 23 is The accommodation recessed part 46 which can accommodate the base 23d is formed. The stacker 23 is disposed in the closed position shown by a solid line in FIG. 3 by the base portion 23d being deeply inserted into the housing recess 46, and in the direction of projecting outward (forward) from the closed position to the main body 12. By moving, it is disposed at the open position (the state of FIG. 2) indicated by a two-dot chain line in FIG. Here, the open position is the position of the stacker 23 in a projecting amount that allows the discharged printed sheet P to be stacked on the stacker 23.

  In the printer 11 of the present embodiment, at the time of the power on operation, only the panel 13 is first opened to the open position shown by the two-dot chain line in FIG. Thereafter, when the print job is received, the stacker 23 performs the projecting operation. As described above, after the panel 13 is first opened and the moving path of the stacker 23 is secured, the stacker 23 is caused to project, so that the two do not collide.

  The printer 11 of this embodiment has a label printing function of printing on the label surface of a disc such as a CDR or a DVD. As shown in FIGS. 2 to 4, a pair of guide grooves 24 (only one is shown in FIGS. 3 and 4) is formed on both sides in the width direction (same as the scanning direction X) at the leading end of the stacker 23. . As shown in FIG. 4, in a state where the stacker 23 is in the closed position, the tray 47 on which the disc (not shown) is set can be slidably inserted into the medium path of the recording unit 28 along the pair of guide grooves 24. There is. That is, by inserting the tray 47 horizontally along the pair of guide grooves 24, the tray 47 is placed on the rollers 37 and 41 and the tip end is nipped by the pair of rollers 37 and 38 at the back side. . The unit supporting the roller 42 constituting a part of the feeding unit 29 engages with the inserted tray 47 and slightly rises, so that the roller 42 is separated from the tray 47, and instead, a small diameter pressing roller 29a Contacts the top surface of the tray 47. Then, the tray 47 is transported to the downstream side in the transport direction Y by using the rollers 37, 38, 41 common to the sheet P, so that the recording head 20 moves on the label surface of the disc set on the tray being transported. Printing is applied.

  In the main body 12, a tray sensor 48 (see FIG. 8) for detecting a tray inserted along the guide groove 24 at the time of label printing is provided. The tray sensor 48 detects that the tray has been taken out along the guide groove 24 after the end of label printing.

  Further, as shown in FIG. 3, in this printer 11, the panel 13 in the closed position is located on the moving path when the stacker 23 moves from the closed position to the open position, and such a layout is adopted As a result, while the width in the height direction of the panel 13 is secured wide, thinning of the main body 12 is realized. As described above, in the printer 11, the area in which the stacker 23 slides out and retreats interferes with the area in which the panel 13 rotates.

  When the icon button is operated in a state where the panel 13 and the stacker 23 are both closed as shown in FIG. 1, the panel 13 and the stacker 23 simultaneously start the opening operation. Also in this case, the panel 13 and the stacker 23 do not collide.

  As shown in FIG. 2, in order to receive the printed paper P, the stacker 23 needs to secure a predetermined delivery amount. Also, the panel 13 is disposed at an attitude angle that is easy for the user to view. Then, when the panel 13 and the stacker 23 close from the open state, the panel 13 closes earlier even if the start of the closing operation is the same, and the stacker 23 closes behind later. At this timing, the protrusion 23 c collides with the lower end portion of the panel 13 before the stacker 23 is completely closed, and the stacker 23 is not further closed.

  Further, since the panel 13 and the stacker 23 can be moved manually by the user, the attitude angle of the panel 13 and the amount of output of the stacker 23 when the closing operation is started can not be determined. For this reason, for example, when the panel 13 has been manually closed or at a closed posture angle of about 10 to 30 degrees, when the stacker 23 is closed, the raised portion 23c is the lower end of the panel 13. I collide with the department. So, in this embodiment, when closing the panel 13 and the stacker 23, the control which adjusts each operation start timing etc. and both do not collide is employ | adopted.

Next, the configuration of the panel 13 will be described with reference to FIG.
As shown in FIG. 5, the panel 13 is a pair of pivots projecting from the upper ends of the both sides by the power transmitted from the first motor 50 (electric motor) as an example of the power source via the power transmission mechanism 51. Between the closed position and the open position, it pivots about a shaft 13a (only one side is shown in FIG. 5). In the present embodiment, the panel 13 is opened in the direction from the closed position toward the open position by the first motor 50 being driven in the forward direction, and the panel 13 is opened in the reverse direction by the first motor 50 being driven in the reverse direction. Close in the direction from the to the closed position.

  The power transmission mechanism 51 has a small diameter gear 53 meshing with the pinion 52 fitted to the drive shaft 50 a of the first motor 50 and the other end of the rotary shaft 54 fitted with the gear 53 at one end. A gear 55 of the same small diameter which is worn and a gear 56 of a large diameter which meshes with the gear 55 are provided. Further, the gear 56 meshes with the gear 57 a of the friction clutch 57, and the rotation of the gear 57 a is transmitted to the two double gears 58 and 59 coaxially disposed, and the small diameter portion 59 a of the double gear 59 is the gear 60. Mesh with A cylindrical gear 61 meshing with the gear 60 meshes with a sector gear 65 formed on the upper side of the panel 13.

  The friction clutch 57 is provided in a state where a fixing portion 57 b fixed to the main body 12 and a gear 57 a are pressed by a coil spring (not shown). Therefore, during driving of the first motor 50, the gear 57a rotates relative to the fixing portion 57b, and the rotation is transmitted to the sector gear 65 through the gears 58 to 61, whereby the panel 13 rotates. . Then, while the first motor 50 is stopped, the panel 13 is maintained in the posture at that time by the frictional force between the gear 57 a and the fixing portion 57 b. The gear 56 is a two-stage gear, and a two-stage gear 64 having substantially the same diameter is coaxially provided next to the gear 56.

  The first motor 50 is provided with an encoder 62 which outputs a detection pulse signal having a number of pulses proportional to the amount of rotation. Further, on the back surface side of the panel 13, a first sensor 63 (panel opening sensor) for detecting a state in which the panel 13 is in the open position is disposed. The first sensor 63 is formed of an optical sensor capable of detecting a plate-like detected portion 13 b extending from the back surface of the panel 13. When the panel 13 is at the attitude angle of the open position, the detected portion 13 b can be inserted into the recess through which the detection light of the first sensor 63 passes. Assuming that the posture angle at which the panel 13 is parallel to the front surface of the main body 12 is 0 degrees and the opening direction is a positive direction, the panel 13 opens and closes in a range of 0 to 90 degrees.

  As shown in FIG. 6, when the panel 13 is opened up to a predetermined angle θ1 when the open position, the detection portion 63a of the first sensor 63 detects the detection portion 13b from the non-detection state in which the detection portion 13b is not detected. Switch to detection state. That is, the state of detection of the first sensor 63 is switched from the state representing closing to the state representing opening. θ1 is, for example, a predetermined angle (about 45 degrees as an example) within the range of 30 to 70 degrees. In the present embodiment, the predetermined angle θ1 is set to an angle at which the panel 13 can be retracted to a position that does not get in the way of the stacker 23 that protrudes during printing. The first sensor 63 may be a contact sensor instead of a non-contact sensor such as an optical sensor.

  Here, the reason why the switching angle of the detection of the first sensor 63 is θ1 ° is as follows. For example, if θ1 is set to 0 °, the panel 13 must be moved to the closed position (0 °) for origination. For example, when the stacker 23 is in a projecting state at that time, the panel 13 is on the stacker 23 There is a concern that the printed paper P will hit. On the other hand, if θ1 is 90 °, for example, the panel 13 is once moved to the fully open position when the power is turned on to perform home position return, and then it becomes an operation to return from the fully open position to the target position. It takes a long time to position 13 at the target position.

  For this reason, in the present embodiment, by setting the switching angle of the detection of the first sensor 63 to θ1, the panel 13 does not hit the printed paper P on the stacker 23 even when closing to θ1 and opens up to θ1. As compared with the case of opening up to the maximum angle (90 degrees as an example), it does not take time, and it is possible to finish the home search early and move the panel 13 to the target position.

  Next, the configuration of the stacker 23 will be described with reference to FIG. The stacker 23 includes a medium receiving surface 23e on the top surface of the base 23d. A pair of racks 69, 69 extending from the upstream side to the downstream side in the projecting direction (same as the transport direction Y) is provided on both sides of the medium receiving surface 23e in the sheet width direction. The racks 69, 69 are fitted at respective positions at predetermined intervals in the axial direction of the rotary shaft 72 constituting the power transmission mechanism 71 to which the power of the second motor 70, which is the power source of the stacker 23, is transmitted. It is in mesh with the pair of pinion gears 73, 73 respectively.

  The stacker 23 moves between the closed position and the open position by the power transmitted from the second motor 70 via the power transmission mechanism 71. In the present embodiment, the stacker 23 moves in the projecting direction from the closed position to the open position by the normal rotation drive of the second motor 70, and by the reverse rotation drive of the second motor 70, the stacker 23 from the open position Move in the retraction direction toward the closed position.

  Further, in the main body 12, a second sensor 74 (stacker open sensor) for detecting the state where the stacker 23 is in the open position is provided. The second sensor 74 detects a cutout recess 23 f formed at the rear end of the stacker 23 when the stacker 23 is in the open state positioned in the range from the open position to the full open. For this reason, the second sensor 74 switches from the open position where the stacker 23 protrudes to the open position to the open position and the open position from the stacker 23 to the open position from the open position to the closed position. Switch to the state.

  The second sensor 74 is a switch type sensor that changes from a state representing the closing of the stacker 23 to a state representing the opening in the open position when the stacker 23 performs an open operation to project outward from the closed state (open side). . The second sensor 74 is, for example, an optical non-contact sensor, but a contact sensor such as a limit switch can also be used. In addition, the second motor 70 is provided with an encoder 75 that outputs a detection pulse signal having a number of pulses proportional to the amount of rotation.

  Further, as shown in FIG. 7, a recess 23g is formed at the center in the width direction of the portion on the upstream side (left side in FIG. 7) of the base 23d in the projecting direction. The stacker 23 is accommodated in the closed position while avoiding the swinging member 32 (see FIG. 3) for supporting the pickup roller 17 by the recess 23g. For this reason, the stacker 23 can be inserted to a deep position in the main body 12 in the closed position. Thus, although the stacker 23 has a single-tray structure, the necessary amount of extension is ensured when the stacker 23 protrudes from the main body 12.

  As shown in FIG. 7, the rotation of the pinion 76 fitted to the drive shaft of the electric motor 70 is transmitted to the gear 78 via the gear 77. A gear train 79 including gears 79 a to 79 g arranged in a state capable of transmitting the rotation of the gear 78 to the lower side of the gear 78 serves as a power transmission path to the stacker 23. A gear 79 g positioned at the final stage on the power transmission path of the gear train 79 is fitted to one end of the rotation shaft 72. By rotating the rotation shaft 72 by the rotation of the gear 79g, the pair of pinion gears 73, 73 is rotated, and the stacker 23 slides in the direction parallel to the transport direction Y via the pair of racks 69 meshed with these. It has become. The gear 79d in the gear train 79 constitutes a part of a friction clutch 79k provided with a friction clutch mechanism, and when a rotational force exceeding a predetermined value is applied to the gear 79d, the power transmission surface slips and idles. By interposing the gear 79d constituting the friction clutch 79k, a relatively light force is required when the stacker 23 is slid in the retracting direction by the user's manual operation, and the meshing noise of the gear is also reduced. Further, the presence of the friction clutch 79k prevents the stacker 23 from temporarily locking even when it strikes an obstacle, so that the second motor 70 is not overloaded.

  In the present embodiment, when the controller 80 (see FIG. 8), which will be described later, switches from a state in which the detection state of the second sensor 74 is closed to a state in which the second sensor 74 is closed during normal rotation driving of the second motor 70, The motor 70 is decelerated while being decelerated. For this reason, the stacker 23 stops at the position on the protruding side by a predetermined distance from the open position. That is, the stacker stops at a position within the open area between the open position and the fully open position.

Next, the electrical configuration of the printer 11 will be described based on FIG.
As shown in FIG. 8, the printer 11 includes a controller 80 as an example of a control unit that controls various controls. The controller 80 is communicably connected to the host device 200 via the communication interface 81. The controller 80 controls the printing operation and the like of the printer 11 based on the print job data received from the host device 200. The host device 200 is, for example, a personal computer and incorporates the printer driver 201. The host device 200 is provided with an input unit 202 including a keyboard and a mouse, and the user operates the input unit 202 to set the paper type, paper size, and printing color on the setting screen displayed on the monitor (not shown) by the printer driver 201. And input and set printing condition information including printing quality and the like. The printer driver 201 generates print image data of an image for which execution of printing is designated based on the print condition information, adds a header including a part of the print condition information to the print image data, and generates print job data, This is sent to the printer 11.

  The carriage motor 40, the conveyance motor 33, the first motor 50, the second motor 70, and the display unit 14 are electrically connected to the controller 80 as an output system. In addition, the controller 80 includes, as an input system, the operation unit 15 including the power switch 15a and the operation switch 15b, the linear encoder 82, the encoders 49, 62, and 75, the first sensor 63 (panel open sensor), and the second sensor 74 A stacker open sensor) and a tray sensor 48 are electrically connected.

  As shown in FIG. 8, the controller 80 includes a computer 85, a head driver 86, motor drivers 87 to 90, and a display driver 91. The computer 85 drives the recording head 20 via the head driver 86 based on the print job data, and draws an image or the like based on the print image data by ejecting ink droplets. Further, the computer 85 drives and controls the carriage motor 40 via the motor driver 87 to control the movement of the carriage 18 in the scanning direction X. At this time, the computer 85 counts the input pulses from the linear encoder 82 with a counter (not shown) to thereby grasp the movement position of the carriage 18 with the home position, for example, as the origin.

  Furthermore, the computer 85 drives and controls the transport motor 33 via the motor driver 89. Here, the pickup roller 17 can be rotated by switching the power transmission switching portion 92 (clutch portion) interposed on the power transmission path of the conveyance motor 33 at the time of sheet feeding. Further, the power of the conveyance motor 33 is transmitted, and the feed drive roller 34, the conveyance drive roller 37, and the first roller 41 rotate. At this time, the computer 85 counts the input pulse from the encoder 49 with a counter (not shown) to grasp the transport position of the sheet P.

  A plurality of sheets of paper P accommodated in the feeding cassette 16 are fed out one by one in order from the top by the pickup roller 17, and the fed-out sheets of paper P are fed by the feeding driving roller 34, the conveyance driving roller 37 and the The paper is conveyed along a predetermined path by the rotation of the first roller 41. Ink droplets are ejected from the recording head 20 which reciprocates in the scanning direction X together with the carriage 18 on the surface of the sheet P at a recording position halfway along the transport path, and an image or a document is printed on the surface of the sheet P.

  Further, as shown in FIG. 8, the computer 85 drives and controls the first motor 50 via the motor driver 89. When the first motor 50 is driven to rotate in the normal direction, the panel 13 rotates in the opening direction, and when the first motor 50 is driven to rotate in the reverse direction, the panel 13 rotates in the closing direction.

  The first sensor 63 (panel open sensor) is turned on in the open area on the open side of the panel 13 relative to the open position of about 45 degrees, and is turned off when the panel 13 is not in the open area. The encoder 62 also outputs a detection pulse signal having a number of pulses proportional to the amount of rotation of the first motor 50 to the computer 85.

  Further, as shown in FIG. 8, the computer 85 drives and controls the second motor 70 via the motor driver 90. When the second motor 70 is driven to rotate in the normal direction, the pinion gear 73 rotates in the normal direction, and the stacker 23 moves in the projecting direction via the meshing between the pinion gear 73 and the rack 69 that perform the normal rotation. On the other hand, when the second motor 70 is reversely driven, the pinion gear 73 is reversely rotated, and the stacker 23 is moved in the direction of being stored in the main body 12 via the meshing of the reversely rotated pinion gear 73 and the rack 69.

  The second sensor 74 (stacker open sensor) is turned on in the open area where the stacker 23 protrudes from the open position and is turned off when the stacker 23 is not in the open area. The encoder 75 also outputs a detection pulse signal having a number of pulses proportional to the amount of rotation of the second motor 70 to the computer 85.

  A computer 85 shown in FIG. 8 is configured to include, for example, a CPU 100, an ASIC 101 (Application Specific IC (Application Specific IC)), a RAM 102, a non-volatile memory 103, and the like. The non-volatile memory 103 stores various programs including a program for stacker control shown by the flow charts in FIG. 12 and FIG. The computer 85 includes a plurality of functional units shown in FIG. 8 that are software configured by the CPU 100 executing a program stored in the non-volatile memory 103. That is, the CPU 100 includes a main control unit 111, a detection unit 112, a determination unit 113, a timer 114, a first counter 115, and a second counter 116 as a plurality of functional units. Of course, the present invention is not limited to the configuration of software using the computer 85, and may be a configuration of hardware such as an electronic circuit (for example, a custom IC) or a configuration by cooperation of software and hardware.

  A main control unit 111 shown in FIG. 8 controls the printer 11 in an integrated manner, controls the operation of the printing system, the panel system and the stacker system, and controls the power supplied to each system. When controlling the printing system, the main control unit 111 controls the recording head 20, the carriage motor 40, and the transport motor 33 via the drivers 86 to 88. The main control unit 111 controls the first motor 50 and the second motor 70 via the drivers 89 and 90 when performing drive control of the panel system and the stacker system. When controlling the panel system and the stacker system, the main control unit 111 detects the detection result of the detection unit 112, the determination result of the determination unit 113, the counting time of the timer 114, each of the first counter 115 and the second counter 116. Use the count value.

  The printer 11 has a power saving function to stop the power supply to at least a part of each system when the elapsed time reaches the set time without various operations such as the switch operation of the panel 13 and the printing operation. doing. For example, when the elapsed time reaches the first set time while there is no switch operation and various operations, the main control unit 111 turns off the display unit 14 and then the second set time longer than the first set time. When it reaches, the printer 11 is switched to the power saving mode in which the power of the printer 11 is automatically turned off. Then, the main control unit 111 returns the power supply to each system, triggered by the start of the switch operation or at least one operation thereafter.

  The detection unit 112 detects an overload applied to each of the first motor 50 and the second motor 70. That is, the detection unit 112 detects an overload in which the load of the first motor 50 when the panel 13 hits the stacker 23 or the end of the movable range exceeds a threshold. The detection unit 112 also detects an overload where the load of the second motor 70 when the stacker 23 hits the panel 13 or the end of the movable range exceeds a threshold. The overload can be detected by detecting that the current value of the motor 50, 70 exceeds a threshold value. In addition, a detection method can be used in which the number of input pulses from the encoders 62 and 75 per unit time, that is, the driving speed of the motors 50 and 70 becomes less than the threshold value to cause an overload. In addition, a detection method can be used in which the time interval between pulse edges from the encoders 62 and 75 exceeds the threshold value to cause an overload. Other overload detection methods may be used, such as detecting the torque of the motors 50 and 70.

  The determination unit 113 performs various determination processes necessary to control the opening operation and the closing operation of the panel 13 and the stacker 23. When the panel movement condition is satisfied, the computer 85 performs panel movement control to move the panel 13 to a predetermined position according to the satisfied condition. The determination unit 113 determines, as the panel movement condition, whether one of the power-off operation signal input, the power saving mode transition, the print job start, the label print start, and the open button operation signal input is satisfied. It is determined whether or not. Further, when the panel return condition is satisfied, the computer 85 performs panel return control to return the panel 13 from the predetermined position moved by the panel movement control to the original panel position before the movement. As the panel recovery condition, the determination unit 113 receives the power on operation signal, returns the power saving mode, detects tray removal after label printing is completed, the print job is completed, or the close button operation signal is input. It is determined whether or not one is established. When the panel return condition is satisfied, this corresponds to a predetermined time when it is not necessary to hold the panel 13 at a predetermined position.

  The timer 114 counts an elapsed time from when the printer 11 is neither operated nor operated. The main control unit 111 turns off the display unit 14 of the panel 13 when the elapsed time for which the timer 114 elapses first reaches the first predetermined time, and supplies the power from the power supply device when the second predetermined time is reached. And shift to a power saving mode in which part of the CPU 100 etc. is stopped.

  The first counter 115 counts the rotational position (angular position) of the panel 13, that is, the panel position. The first counter 115 detects the panel position when the first sensor 63 detects that the panel 13 is in the open position, or the position where the panel 13 strikes the end of the movable range from the encoder 62 with the origin as the origin Pulse edges of the detection pulse signal of The first counter 115 increments the count value when the panel 13 is opened, and decrements the count value when the panel 13 is closed.

  The second counter 116 counts the position of the stacker 23. The second motor 70 is used to grasp the position of the stacker 23 which is necessary when controlling the speed of the second motor 70 in the section from the movement start position of the stacker 23 to the stop position according to the position of the stacker 23 from time to time. The second counter 116 is reset at the start of movement of the stacker 23, increments the number of pulse edges of the detection pulse signal from the encoder 75 when the stacker 23 opens and decrements it when the stacker 23 closes. . The main control unit 111 controls the speed of the stacker 23 by outputting a command value corresponding to the value of the second counter 116 to the motor driver 90.

  Further, the main control unit 111 controls the first motor 50 and the second motor 70 so as not to collide in the interference area when the panel 13 and the stacker 23 are both opened, and both the panel 13 and the stacker 23 are closed. The first motor 50 and the second motor 70 are controlled so as not to collide in the interference area when operating.

  The panel movement control routine and the panel return control routine will be described below with reference to FIGS. 9 to 11. Here, in the case of moving the panel 13 to a predetermined position due to the circumstances of the printer 11, the panel movement control is a position before the user moves the panel 13 to a predetermined position where the angle is adjusted etc. Control of moving the panel 13 to a predetermined position while storing the position. In addition, this panel return control moves the panel 13 to a predetermined position due to the circumstances of the printer 11, and then, at a predetermined time when it is not necessary to hold the panel 13 in the predetermined position, the panel 13 is moved to the predetermined position. It is control to return to the original position before movement to

  As shown in FIG. 9A, when the power on operation of the printer 11 is performed, the controller 80 controls the first motor 50 so that the panel 13 pivots forward from the closed position shown in FIG. It is placed in an open position opened at a predetermined attitude angle (for example, 45 degrees). From the open position, the user further manually adjusts the angle of the panel 13 by manual operation, for example, to an easy-to-see angle shown by a solid line in FIG.

  When the power is turned off in the state shown in FIG. 9A, the controller 80 controls the first motor 50 to move the panel 13 from the open position shown by the two-dot chain line in FIG. Move it. At this time, the controller 80 reads panel position data indicating the panel position immediately before starting the movement of the panel 13 to the closed position by reading the value of the first counter 115 and acquires the panel position data in a predetermined storage area of the non-volatile memory 103. Write. Therefore, the non-volatile memory 103 stores panel position data manually adjusted by the user. Also, at the time of transition to the power saving mode, the controller 80 performs the same control as at the time of power off.

  Next, when the power on operation of the printer 11 is performed in the state shown in FIG. 9B, the panel position data read out from the predetermined storage area of the non-volatile memory 103 from the closed position shown by the two-dot chain line in FIG. The specified user returns to the panel position shown by the solid line that was last adjusted before power off.

  Also, when returning to the power saving mode, the same control as when the power is turned on is performed. That is, the controller 80 immediately before the user shifts to the power saving mode defined by the panel position data read from the predetermined storage area of the nonvolatile memory 103 from the closed position shown by the two-dot chain line in FIG. It returns to the panel position shown by the solid line which adjusted the angle to.

  Here, as shown in FIG. 10, when the stacker 23 on which the printed sheet P is loaded is projected in the open state, the panel 13 is not closed even if the power of the printer 11 is turned off. . This is because the printed sheet P may be placed on the stacker 23 when it is in the projecting state, so that the stacker 23 does not hit the sheet P on the stacker 23. When projecting in the open state, the panel 13 is not closed even if the power is turned off.

  Further, as shown in FIG. 11A, at the start of the print job, the controller 80 controls the first motor 50 to start the panel 13 from the user's adjustment position shown by the two-dot chain line in FIG. It moves to the open position (for example, 45 degrees) shown by a solid line in the figure. By separating the panel 13 from the passage of the stacker 23, the passage of the stacker 23 is opened to avoid the interference between the panel 13 and the stacker 23, and the printed paper P received by the stacker 23 is not hit by the panel 13. The open position where the panel 13 stands by at the time of printing corresponds to the standby position as an example of the predetermined position at the time of printing.

  Further, as shown in FIG. 11B, at the start of label printing, the controller 80 controls the first motor 50 to start the panel 13 from the user's adjustment position shown by the two-dot chain line in FIG. It moves to the full open position (for example, 90 degrees) shown by a solid line in the figure. That is, the panel 13 is retracted to a panel position where the passage of the tray 47 inserted substantially horizontally along the pair of guide grooves 24 of the stacker 23 can be secured.

  Also, as shown in FIG. 11C, for example, when the user adjusts the angle of the panel 13 to the panel position on the open side (for example, 45 degrees) from the open position (for example, 45 degrees), The passage of the stacker 23 is sufficiently secured at a certain open position (45 degrees) or on the open side. In this case, since the panel position holding condition is satisfied, the panel position is held and the panel 13 is not moved. Further, as shown in FIG. 11C, for example, when the user adjusts the angle of the panel 13 to the fully open position (for example, 90 degrees), the fully open position (90 degrees) corresponding to the start of the print job The path of the tray 47 to be inserted along the guide groove 24 at the time of label printing is already secured. In this case, since the panel position holding condition is satisfied, the panel position is held and the panel 13 is not moved.

Next, the operation of the printer 11 configured as described above will be described.
In the printer 11 according to the present embodiment, the computer 85 executes the panel movement control program shown in FIG. 12 and the panel return control program shown in FIG. When the printer 11 is powered on for the first time, the panel position information is not stored in the non-volatile memory 103. Therefore, when the user performs a power on operation, the panel 13 opens and the panel 13 stops at an open position of about 45 degrees at which the first sensor 63 switches from a closed state to an open state (see FIG. 9 (a) two-dot chain line position). The user manually adjusts the angle of the panel 13 to an attitude angle that is easy to view or operate (the position of the solid line in FIG. 9A).

  The panel movement control routine will be described first with reference to FIG. In this panel movement control, when the panel 13 is moved to a predetermined position due to the circumstances of the printer 11, a position before the user moves the panel 13 to a predetermined position where the angle is adjusted etc. (original position ) Is controlled to move the panel 13 to a predetermined position.

  First, in step S11, it is determined whether a panel movement condition is satisfied. That is, it is determined whether any one of the power-off operation signal input, transition to the power saving mode, print job start, label print start, and button operation signal input is established. If the panel movement condition is satisfied, the process proceeds to step S12. If the panel movement condition is not satisfied, the process of step S11 is repeated until the panel movement condition is satisfied.

  In step S12, it is determined whether the panel is stopped. If the panel is stopped, the process proceeds to step S13, and if not stopped, that is, if the panel 13 is moving, the process waits until it is stopped. When the user manually adjusts the angle of the panel 13 to a desired angle, it is determined that the user is not stopping because the panel 13 is moving. At this time, the user stands by until the angle adjustment is finished and the panel 13 is stopped. When the panel 13 is stopped (affirmative determination in S12), the process proceeds to step S13.

  In step S13, the panel position (angle) is acquired and written in the non-volatile memory 103. Specifically, the count value of the first counter 115 counting the value of the panel position is acquired, and the count value is written to the non-volatile memory 103 as panel position information indicating the panel position.

  In step S14, it is determined whether a panel position holding condition is satisfied. Here, the panel position holding condition is a condition which already exists at a position where the panel 13 does not need to be moved and can hold the current panel position, and the panel 13 is moved to a predetermined position according to the satisfied panel movement condition. This is a condition that makes movement unnecessary. For example, when the power-off operation signal is input, the predetermined position is the closed position, and when it is already at the closed position, the panel position holding condition is satisfied because the movement to the closed position is unnecessary. As described above, when the panel 13 is already at a predetermined position corresponding to the satisfied panel movement condition or at a position equivalent to the predetermined position, the panel 13 is held as it is without being moved. When the panel position holding condition is satisfied, the routine ends. On the other hand, if the panel position holding condition is not satisfied, the process proceeds to step S15.

  In step S15, the panel is moved to the set position (predetermined position). That is, the computer 85 drives and controls the first motor 50 to move the panel 13 to the set position if the current panel position is not at the set position or more. Here, the position above the set position indicates, for example, the fully closed position if the set position is the fully closed position (0 degree), and indicates the fully open position if the set position is the fully open position (90 degrees). Further, the position above the setting position means a position at 45 degrees or more if the setting position is 45 degrees.

  For example, at the time of power off operation, the panel 13 is disposed at the closed position (FIG. 9 (b)). For this reason, since the panel 13 is disposed in the closed position while the power is off, it does not get in the way. Further, at the time of transition to the power saving mode, the panel 13 is disposed at the closed position (FIG. 9B). For this reason, since the panel 13 is disposed in the closed position during the power saving mode, it does not get in the way. However, when the stacker 23 is in the open state (FIG. 10), there is a possibility that the sheet P after printing on the stacker 23 may come into contact, so the panel 13 is not moved to the closed position.

  When the print job is started, the panel 13 is moved to the set position (about 45 degrees) (FIG. 11A). At this time, in conjunction with the operation of the panel 13, the stacker 23 protrudes in an open state capable of receiving the printed sheet P. For this reason, the panel 13 opens in a posture of about 45 degrees, and the path of the stacker 23 is secured, so that the panel 13 does not get in the way when the stacker 23 protrudes. Further, during printing, the panel 13 is held at an attitude of about 45 degrees, so that the panel 13 does not contact the printed paper P on the stacker 23, for example.

  Further, when label printing is started, the panel 13 is moved to the set position (90 degrees) away from the insertion path of the tray 47 (FIG. 11B). As shown in FIG. 11C, since the panel 13 is retracted upward (to the fully open position), the user records the tray 47 on which the disc is mounted along the pair of guide grooves 24 in the main body 12 The panel 13 does not get in the way when inserted horizontally into the section 28.

  At step S16, the stacker is moved to the set position. For example, if the power is off, the stacker 23 is moved to the closed position (0 degrees). Further, when the print job is started, the stacker 23 is moved to the open position (45 degrees). Further, at the start of label printing, the stacker 23 is moved to the closed position (0 degrees). This is because the insertion of the tray 47 for label printing needs to be performed with the stacker 23 stored in the closed position. Further, in the power saving mode, the stacker 23 is set so as not to move, but may be moved to the closed position as in the power-off mode.

  In this way, when the panel 13 is powered off, shifts to the power saving mode, receives a print job, starts label printing, and receives an open button operation signal, the panel 13 is at a set position (predetermined position) according to the trigger of these panel movement conditions. When moving, the controller 80 writes the panel position immediately before the start of the movement of the panel 13 in the non-volatile memory 103. Then, the controller 80 drives and controls the first motor 50 to move the panel 13 to the set position corresponding to the trigger of the panel movement condition.

  Next, the panel return control routine will be described with reference to FIG. This panel return control moves the panel 13 to a predetermined position after moving the panel 13 to a predetermined position due to the circumstances of the printer 11, and at a predetermined time when it is not necessary to hold the panel 13 in the predetermined position. It is control to return to the original panel position before movement.

  First, in step S21, it is determined whether a panel return condition is satisfied. That is, it is determined whether any one of the power on operation signal input, the power saving mode return, the tray removal detection after label printing end, the print job end, and the close button operation signal input is satisfied. . If the panel return condition is satisfied, the process proceeds to step S22. If the panel return condition is not satisfied, the process of step S21 is repeated until the panel return condition is satisfied.

  In step S22, it is determined whether or not the origin has been detected. For example, if the origin detection flag is a value indicating success, it is determined that the origin is detected, and if the origin detection flag is a value indicating failure, it is determined that the origin is not detected. If the origin is not detected, the process proceeds to step S23. If the origin is detected, the process proceeds to step S25.

  In step S23, an origin detection operation is performed. That is, first, the panel state is confirmed, and it is confirmed whether the panel 13 is open or closed. That is, if the detection state of the first sensor 63 is a closed state, it is determined that the panel 13 is closed, and if the detection state is an open state, it is determined that the panel 13 is open. That is, it is determined that the panel 13 is closed if it is on the close side of the switching position between the open and close by the first sensor 63 and if it is on the open side, it is determined that it is open. If the panel 13 is closed, the panel 13 is moved from the position in the opening direction while confirming a change in the detection state of the first sensor 63. If the panel 13 is open, the panel 13 is moved in the closing direction while confirming the change in the detection state of the first sensor 63 from the position. Then, if there is a change in the detection state of the first sensor 63, the value of the first counter 115 is reset at the position at the time of the change to set the origin, and the first motor 50 is decelerated and stopped. Causes the panel 13 to stop. Then, the origin detection flag in the non-volatile memory 103 is set to a value indicating success. On the other hand, when an overload is detected by hitting the end of the movable range or the like without any change in the detection state of the first sensor 63, the origin detection flag in the non-volatile memory 103 is set to a value indicating failure. .

  In step S24, it is determined whether origin detection has succeeded or failed. If the origin detection is successful, the process proceeds to step S25. If the origin detection is unsuccessful, the panel return control routine is ended. In this case, since the correct position of the panel 13 can not be grasped, the panel return operation for returning the panel 13 to the original position is not performed.

  In step S25, panel position information is read from the memory. That is, the value of the panel position written in the non-volatile memory 103 in step S13 immediately before the panel movement control routine is read out.

  At step S26, the panel is returned to its original position. That is, the computer 85 drives the first motor 50 in the direction in which the value of the first counter 115 approaches the value of the panel position information. Then, the computer 85 controls the first motor 50 while monitoring the value of the first counter 115, and stops the panel 13 at the position where the value of the first counter 115 reaches the value of the panel position information. Thus, the panel 13 returns, for example, to the original position adjusted by the user.

  Thus, when the power on operation signal is input, the panel 13 moves from the closed position to, for example, the panel position where the user adjusts the angle before power off (FIG. 9C). In addition, when returning to the power saving mode, if the panel 13 is moved to the closed position at the time of transition to the power saving mode, the panel 13 moves from the closed position to the original panel position adjusted by the user, for example (FIG. 9C) ). Further, at the time of detection of removal of the tray 47 after the end of label printing, the panel 13 is moved from the closed position to, for example, the original panel position angle-adjusted by the user (two-dot chain line in FIG. 11B). When the close button operation signal is input, the stacker 23 is stored in the closed position, and the panel 13 is moved to the original position immediately before the start of printing (FIG. 11 (d)).

  Further, when the print job is finished, if the original panel position based on the panel position information is at the open side including the guaranteeable position that the panel 13 does not contact the sheet P on the stacker 23, the stacker 23 With the open position, the panel 13 is returned to the original position (for example, FIG. 10). The configuration may be such that the panel 13 is not moved at the end of the print job. Further, a sensor is provided to detect the presence or absence of the sheet P on the stacker 23. If the sensor detects the sheet P on the stacker 23, the stacker 23 is not retracted and the sensor does not detect the sheet P on the stacker 23. Alternatively, the stacker 23 may be retracted and the panel 13 may be returned to the original position, for example, the user's angle adjustment immediately before the start of printing.

According to the first embodiment described above, the following effects can be obtained.
(1) The printer 11 includes a panel 13 provided to be adjustable in angle with respect to the main body 12, a first motor 50 (an example of a motive power source for driving the panel 13), and a controller 80 for controlling the first motor 50 ( An example of the control unit). The controller 80 writes the panel position immediately before moving the panel 13 to a predetermined position into the non-volatile memory 103 (an example of a storage unit) and drives the first motor 50 to move the panel 13 to the predetermined position. Thereafter, at the predetermined time when it is not necessary to hold the panel 13 in the predetermined position, the first motor 50 is driven to return the panel 13 to the original panel position read from the non-volatile memory 103. Therefore, the user returns the panel 13 to the original panel position because the panel 13 returns from the predetermined position to the original panel position at a predetermined time even if the controller 80 moves the panel 13 to the predetermined position. You do not have to

  (2) The controller 80 sets the position according to one of the predetermined positions as the predetermined position when the power is off, when the power saving mode is entered, when the display of the panel 13 is turned off, or when printing is started. The panel 13 is moved to store the position of the panel before moving the panel 13 in the non-volatile memory 103. Then, at a predetermined time when it is not necessary to hold the panel 13 in the set position, the panel 13 is returned to the original panel position stored in the non-volatile memory 103. Therefore, the user does not have to return the panel 13 to the original panel position even when the controller 80 moves the panel 13 to the setting position at that time.

  (3) The controller 80 reads out the panel 13 from the non-volatile memory 103 with any one of power on, return from power saving mode, end of printing, and stacker close button operation as a predetermined time. Move to the original panel position. Therefore, even if the controller 80 moves the panel 13 to a predetermined position (set position), the user does not have to return the panel 13 to the original panel position.

  (4) When the storage timing for writing the panel position to the non-volatile memory 103 comes, the controller 80 waits for the panel 13 to stop if the panel 13 is moving, and the panel 13 stops at the position where the panel 13 stopped. It writes to the non-volatile memory 103 as a position. Therefore, thereafter, at a predetermined time when it is not necessary to hold the panel at a predetermined position (set position), the panel 13 does not return to a position on the way of moving the panel 13 by the user. The panel 13 can be returned to the panel position where it has been stopped.

  (5) If the panel 13 moves at the time of transition to the power saving mode, the controller 80 waits until the panel 13 stops, writes the panel position when the panel 13 stops to the non-volatile memory 103, and then After moving to the closed position which is a predetermined position (set position) in the power saving mode, the power saving mode is entered. Therefore, when returning from the power saving mode (predetermined time), the panel 13 can be returned to the panel position where the user has stopped the panel 13.

  (6) The controller 80 moves the stacker 23 to the open position at the start of printing and moves the panel 13 to an open position (standby position at printing) as an example of a predetermined position at printing, and the panel 13 The panel position before movement is written to the non-volatile memory 103. At a predetermined time after printing is completed, the panel 13 is returned to the original panel position read from the non-volatile memory 103. Therefore, the user does not have to return the panel 13 to the original position before the start of printing after the end of printing.

  (7) The printer 11 is configured to be capable of label printing on a disc in a state where the tray 47 capable of loading the disc is inserted from the insertion portion. The controller 80 moves the panel 13 as a predetermined position to a predetermined angle away from the insertion path of the tray 47 at the time of label printing, and writes the panel position before moving the panel 13 to the predetermined angle in the non-volatile memory 103. Therefore, the user can easily insert the tray 47 on which the disc is placed from the insertion portion. The controller 80 returns the panel 13 to the original panel position read out from the non-volatile memory 103 at a predetermined time by detecting that the tray 47 that has finished label printing has been taken out by the user. If the panel 13 returns to its original position before taking out the tray 47, the panel 13 blocks the taking out path of the tray 47, which becomes an obstacle when taking out the tray 47. However, since the panel 13 returns to the original position after the removal of the tray 47 is detected, the tray 47 can be removed without the panel 13 getting in the way.

In addition, the said embodiment can also be changed into the following forms.
The power saving function of the printer 11, when the display unit 14 of the panel 13 is turned off when the elapsed time reaches the first predetermined time with neither switch operation nor various operations in a predetermined position (for example, It may be configured to move to the closed position). That is, when the display unit 14 of the panel 13 is turned off is added to the step S11 in the panel movement control routine as one of the panel movement conditions. In this case, the panel position information before the start of movement of the panel 13 to the closed position is written to the non-volatile memory 103, and thereafter, at a predetermined time triggered by the start of switch operation or operation which is a condition for returning from this mode. The screen of the display unit 14 is turned on, and the first motor 50 is driven to return the panel 13 to the original panel position based on the panel position information read from the non-volatile memory 103. Even with this configuration, even when the controller 80 moves the panel 13 to the closed position when the display unit 14 is turned off, a predetermined time when the panel 13 does not need to be held at the closed position (for example, the time to return the display unit 14 to the display state) Then, since the panel 13 is returned to the original panel position, the user does not have to return the panel 13 to the original panel position.

  The position (angle θ1) at which the first sensor 63 switches from the state representing the closing of the panel 13 to the state representing the opening is not limited to the position of about 45 degrees, and is fully closed such as about 30 degrees or about 60 degrees It may be another position in the intermediate angular range with the full opening, and is not limited to the position in the intermediate angular range. The angle θ1 may be a fully open angle (for example, 90 degrees) or a fully closed angle (for example, 0 degrees). Note that full open refers to the angular position that is maximally open in the movable range of the panel, and full close refers to the angular position that is most closed in the movable range of the panel.

  -The origin when measuring the position of the panel 13 is changed to a configuration in which the detection position of the first sensor is switched, and at least one of the fully closed end and the fully open end of the panel 13 is hit. The position of the panel when the overload at the time of detection is detected may be set as the origin. In this case, the elimination of the first sensor 63 can reduce the number of components.

  · As a panel movement condition in step S11 in FIG. 12, when the power off operation signal is input, when the power saving mode is entered, when the print job is started, when the label printing is started, when the open button operation signal is entered, and when the display of the panel is off Only one of them may be adopted, and optionally two, three, four or five of these may be adopted.

  · As a panel return condition in step S21 of FIG. 13, any of the power on operation signal input, the power saving mode return, the tray removal detection after label printing end, the print job end, and the close button operation signal input Only one of them may be adopted, and optionally two, three or four of them may be adopted.

The movement paths of the panel 13 and the stacker 23 may not overlap each other.
Although the power source of the stacker and the power source of the panel are separately provided, one of the power source of the stacker and the power source of the panel may be combined with a motor provided for another application. For example, the transport motor 33 may be one of the power source of the panel 13 and the power source of the stacker 23. In this case, a clutch capable of switching the power transmission destination of the transport motor 33 to the stacker is provided. The clutch may be an electric clutch, or may be a mechanical clutch for switching the clutch by a switching lever provided on the carriage 18 by driving the carriage motor to move the carriage to a predetermined position.

  The pivot shaft 13a may be disposed at the lower end when the panel 13 is in the closed position, and the panel may be configured to open upward. In addition, the pivot shaft is disposed at the left end when the panel is in the closed position to make the panel open to the right, or the pivot shaft is disposed at the right end when the panel is in the closed position. May be left open. Further, the arrangement position of the panel is not limited to the front surface of the main body (housing), but may be a side surface, an upper surface, or a back surface. In addition, a plurality of panels may be provided on the main body. In this case, the plurality of panels may be provided on the same side of the main body, or may be provided on different sides of the main body. Then, if at least one of the plurality of panels is motorized and the controller moves the panel to a predetermined position, then at a predetermined time, the controller writes the panel to the non-volatile memory, and the original panel Control may be performed to return to the position.

  In the embodiment, the panel is pivotable, but may be slide. Further, it may be a compound movable type panel having a slide mechanism and a pivot mechanism. For example, the panel slides from the inside of the body and protrudes outward, and then the panel is pivoted to be disposed at an adjustment angle adjusted by the user. In this case, both the slide mechanism and the pivot function may be driven by a common motor or may be driven by separate motors.

  The panel 13 may not include the operation unit such as the operation switch, and may be configured to include only the touch panel type display unit capable of performing an input operation by touching the screen with a hand. Further, the configuration may be such that only the operation unit is provided without the display unit. Further, the panel is not limited to the operation panel, and may be a panel provided with a display unit having only a display function. In the case of a display panel provided with a display unit, even if the controller 80 moves the panel to a predetermined position (for example, a predetermined angle) after adjusting the panel to an angle at which the user can easily view the display unit, At a predetermined time (restoring time) at which it is not necessary to hold the panel in a predetermined position, the panel returns to the original panel position, so the user can easily view the display portion on the panel without having to return the panel. Further, in the case of an operation panel provided with an operation unit, the controller 80 moves the panel to a predetermined position (for example, a predetermined angle) after adjusting the angle of the panel to an angle at which the user can easily operate the operation unit. After that, when the predetermined time comes, the panel returns to the original panel position, so that the user can easily operate the operation unit on the panel without the operation of returning the panel. Furthermore, the panel may have neither the operation unit nor the display unit. For example, the cover panel may be an angle adjustable cover panel for opening and closing a sheet insertion port, or may be an angle adjustable cover panel for opening and closing a sheet discharge port. Also, a medium supporting panel such as an adjustable-angle medium support for setting a medium such as a sheet for feeding, or a medium receiving panel such as an adjustable-angle stacker that receives a medium such as a discharged sheet Good.
