Description of the Related Art Conventionally, recording apparatuses such as ink jet printers not only transport a sheet, which is an example of a transported medium, from a paper cassette, which is a sheet storage unit, one by one, but also record on the recording unit. And board paper can be transported to a transport path and recorded by a recording unit (for example, Patent Documents 1 and 2).

  In this recording apparatus, when recording a sheet having a certain degree of flexibility, such as plain paper, the sheet is fed from the sheet cassette to the recording unit, recorded by the recording unit, and then discharged to the medium receiving tray by the discharging unit. Sent out. On the other hand, optical disks and board papers have low flexibility (high rigidity) and cannot be transported on curved transport paths. Unlike plain paper, the optical disks and board papers are horizontal from the downstream side toward the transport path. (Linearly) and after being recorded by the recording unit, it is discharged horizontally (linearly) toward the front of the apparatus.

  Since the optical disk is small in size and cannot be transported in the transport path of the recording apparatus as it is, in many cases, the optical disk is supplied into the transport path in a state of being set on a flat tray (hereinafter referred to as “disk tray”). The In the following description, for convenience of explanation, the transport medium with low flexibility will be described using a disk tray as an example.

  In a recording apparatus capable of transporting a disk tray, a guide (hereinafter referred to as “tray guide”) for supplying the disk tray horizontally is provided on the front side of the apparatus (downstream side of the discharge means). Note that this tray guide may be provided as a dedicated member as shown in Patent Document 1, or a medium receiving tray that receives plain paper or the like may have the function as shown in Patent Document 2.

It will be in the state which receives conveyance force from the drive roller 24. FIG.

  When recording is performed on the optical disk D set on the disk tray 60, the disk tray 60 receives the transport force from both the transport drive roller 24 and the discharge drive roller 31, and the disk tray 60 that has finished recording on the optical disk D is recorded. When ejected forward of the apparatus, the disc tray 60 receives a conveying force from the ejection drive roller 31.

■■■ 2. Details of the paper receiving tray 8 ■■■■■■■■■■■■■■■■■■■■■■■
The above is the overall configuration of the printer 1, and the paper discharge receiving tray 8 as a medium receiving tray will be described in further detail below.
In FIG. 7, in the present embodiment, the sheet receiving tray 8 is formed of a single member in the entire area of the sheet receiving surface 8 a that receives the sheet P as a sheet material, that is, a single-stage type rather than a multistage type (drawer type). It is configured as a tray. More specifically, in this embodiment, the entire paper discharge receiving tray 8 is integrally formed of a resin material. As a result, the overall rigidity of the paper discharge receiving tray is improved, and the cost is reduced by simplifying the structure.

  The discharge receiving tray 8 has a side end (end in the direction intersecting the sheet discharge direction (sheet width direction)) 8e slidable with respect to the frame 34 (FIG. 8) constituting the base body of the apparatus main body 2. It is supported by. Rack portions 8f are formed along the paper discharge direction at both ends of the paper discharge tray 8 (both ends in a direction crossing the paper discharge direction).

Two pinion gears 44 are provided at a predetermined interval in the axial direction of the rotary shaft 45, and the rotary shaft 45 receives the power of the motor 43 through the toothed wheel train 46 constituting the driving means 42, and thus the motor The sheet receiving tray 8 is displaced (sliding) by the rotation of 43. In the present embodiment, the rack portion 8f is formed at both end portions, but may be formed only at one end side.

  The motor 43 that constitutes the driving means 42 is controlled by the control unit 40, so that the paper discharge receiving tray 8 is stored in the storage position (second position: FIGS. 1, 3, 4, and 5 under the control of the control unit 40. ) And the most projecting position (first position: FIGS. 2 and 6). Further, the control unit 40 can grasp the current position of the paper discharge receiving tray 8 based on the signal received from the tray position detecting means 41. In addition, the control unit 40 can grasp whether or not the disc tray 60 is set in the paper discharge receiving tray 8 based on a signal received from the disc tray detection means 55 (details will be described later).

Note that the tray position detecting means 41 according to the present embodiment has any one of the three states, that is, whether the paper discharge receiving tray 8 is at the most protruding position, at the storage position, or at any position. Is returned to the control unit 41.
As shown in FIG. 8, the tray position detection means 41 includes a first position detection sensor 41b and a second position detection sensor 41a. These sensors are contact sensors that come into contact with the paper discharge receiving tray 8 in this embodiment, but may be non-contact sensors that do not come into contact with the paper discharge receiving tray 8 such as an optical sensor.

  FIG. 12 shows the positional relationship between the first position detection sensor 41b and the second position detection sensor 41a (the positional relationship in the state provided in the apparatus main body 2) (in addition, the disk tray detection means 55 described later). Also shows location). S1 and S2 indicate lines sensed by the first position detection sensor 41b and the second position detection sensor 41a, respectively, in accordance with the movement operation of the discharge receiving tray 8, and the sensing lines S1 and S2 are discharged as shown in the figure. The sensors are arranged so that their positions do not match in the width direction of the paper receiving tray 8 (left and right direction in FIG. 12).

  FIG. 12 shows a state where the paper discharge receiving tray 8 is in the storage position (second position). In this state, each sensor is at a position facing the upper surface of the paper discharge receiving tray 8. It is detected that it is in the storage position (second position). Further, a detected groove 8q is formed on the sensing line S1 on the upstream side in the discharge direction in the discharge receiving tray 8, and the first position is detected when the discharge receiving tray 8 is displaced to the most protruding position (first position). The detection sensor 41b faces the detected groove 8q. Accordingly, when the paper discharge receiving tray 8 is at the most protruded position (first position), each sensor does not face the upper surface of the paper discharge receiving tray 8, thereby causing the paper discharge receiving tray 8 to be at the most protruded position (first position). ) Is detected. Reference numeral 41 b ′ indicates the position of the first position detection sensor with respect to the paper discharge receiving tray 8 when the paper discharge receiving tray 8 is at the most protruding position.

  As described above, in the present embodiment, the position detection unit of the discharge receiving tray 8 is configured by two sensors. However, the position detection unit is not limited to such a form. For example, the position detection unit is configured by a rotary encoder that detects the rotation amount of the motor 43. You may comprise, or you may combine the two sensors mentioned above and the said rotary encoder. The control unit 40 determines the position of the discharge receiving tray 8 based on the position detection information of the discharge receiving tray 8 by the tray position detecting means 41, the rotation direction and the rotation amount of the motor 43, as the storage position and the most protruding position. Can be adjusted between.

  Next, referring back to FIG. 7, on both downstream sides of the paper receiving surface 8 a that receives the paper P in the paper discharge receiving tray 8, raised portions 8 d are formed on which both ends in the paper width direction ride. With respect to the sheet having a size in which both end portions ride on the raised portion 8d, the fall of the sheet from the discharge receiving tray 8 is prevented by the ride on the leading end of the sheet. Further, curling is formed on the paper as both ends of the paper run. As a result, it is possible to prevent the leading end of the sheet from protruding from the leading end of the discharge receiving tray 8 and dropping and eventually falling. An inclined guide surface 8c is formed on the upstream side of the raised portion 8d so that the leading end of the sheet can smoothly get over the raised portion 8d without being caught by the raised portion 8d.

  On the other hand, in the case of a sheet having a width where both end portions do not climb on the raised portion 8d, in most cases, the leading end of the sheet does not protrude from the leading end of the discharge receiving tray 8, and may fall from the discharge receiving tray 8. There is no. In addition, an inclined guide surface 8b is formed downstream of the central region of the paper receiving surface 8a (between the two raised portions 8d), and is connected to the high-position support surface 8j that is one step higher than the paper receiving surface 8a. For the paper having a width that does not allow the both ends to ride on the raised portion 8d, the inclined guide surface 8b and the high-position support surface 8j prevent the paper from falling from the paper receiving tray 8.

  Subsequently, a tray guide surface 8h that supports and guides the disc tray 60 is formed on the raised portion 8d. The tray guide surface 8h is formed at a position slightly higher than the high-position support surface 8j as shown in FIG. 9, and the height position is supplied horizontally toward the disc tray 60 toward the conveyance path of the apparatus main body 2. It is set to a position where it can.

  The tray guide surfaces 8h provided at both ends in the width direction of the paper discharge receiving tray 8 are formed so that the arrangement interval and width can support (guide) the disc tray 60, and the disc tray 60 With both ends supported by the tray guide surface 8h, the paper is inserted into the apparatus main body 2 from the discharge driving roller 31 from the downstream side in the discharge direction.

  A flange portion 8k is formed on the upper portion of the tray guide surface 8h, and the posture of the disk tray 60 is regulated by the flange portion 8k so that both end portions of the disc tray 60 are not lifted from the tray guide surface 8h. It has become. A tray support protrusion 8g is formed slightly inside the tray guide surface 8h. After the disk tray 60 is supplied to the transport path, the disk tray 60 is supported by the discharge drive roller 31 and the tray support protrusion 8g. The horizontal posture is maintained.

Next, a detection lever 56 as a lever member constituting the disc tray detection means 55 is provided inside the raised portion 8d on the right side when viewed from the front side of the apparatus, as shown in FIGS. ing. The detection lever 56 is provided so as to be able to swing clockwise and counterclockwise about the swing shaft 56d as viewed from the side of the paper discharge path (travel path of the disc tray 60).
As shown in FIG. 10, the detection lever 56 has a swing shaft 56a, a detection side extending portion 56b extending from the swing shaft 56a, and a contact side extending portion 56d extending on the opposite side. Are integrally formed of a resin material.

  The detection-side extending portion 56b is bent upward in an L shape. When the detection lever 56d is provided on the raised portion 8d, the upper end of the detection-side extending portion 56b (hereinafter referred to as “lever contact portion 56c”). However, it can be exposed from the opening 8m formed in the raised portion 8d as shown in FIG. The contact-side extending contact portion 56d has a shape that rises upward, and when the detection lever 56d is provided on the raised portion 8d, the portion that rises upward (hereinafter referred to as “tray contact portion 56e”). However, it can project upward from the opening 8r formed in the raised portion 8d. That is, the tray contact portion 56e protrudes upward from the tray guide surface 8h so that it can come into contact with the disc tray 60.

  The detection lever 56 is urged by a biasing means (not shown) in a swinging direction in which the tray contact portion 56e protrudes upward and the lever contact portion 56c is hidden inside the opening 8m (FIG. 13). And clockwise direction in FIG. 14). In this state, the upper end of the tray contact portion 56e contacts the lower surface of the flange portion 8k, and the posture of the detection lever 56 is maintained.

  From such a state (the state of FIGS. 9 and 13), when the disc tray 60 is passed between the tray guide surface 8h and the flange portion 8k, the disc tray 60 pushes the tray contact portion 56e downward, The detection lever 56 is swung counterclockwise in FIG. Then, as shown in FIG. 14, the lever contact portion 56c protrudes upward from the opening 8m.

  Here, the apparatus main body 2 is provided with a detector main body 57 and a detector 58 constituting the “detection unit” of the disk tray detection means 55 (refer to FIG. 8 for the position of the detector main body 57). When the receiving tray 8 is in the storage position, the detector main body 57 and the detector 58 are positioned above the opening 8m formed in the paper discharge receiving tray 8. Therefore, when the lever contact portion 56c protrudes upward from the opening 8m, the detector 58 is pushed upward (FIG. 14). The detector 58 is swingably provided on the detector main body 57 constituting the disc tray detection means 55, and hangs down from the detector main body 57 above the opening 8m.

  In the state of FIG. 13, the disk tray detection means 55 detects the “no state” of the disk tray 60, but the lever contact portion 56c pushes the detector 58 upward as shown in FIG. Detects the “present state” of the disc tray 60. The disc tray detection means 55 returns the detection signal to the control unit 40 (FIG. 7), whereby the control unit 40 can execute control corresponding to the detection signal.

  A protrusion 8n is formed on the upper portion of the opening 8m along the periphery of the opening 8m (FIGS. 9, 13, and 14), whereby the leading edge portion of the paper P passing above the opening 8m. Is difficult to enter the opening 8m. In addition, the ridge 8n is formed with a slope 8p that guides the leading edge of the paper P so as to get over the protruding ridge 8n, and is configured so that the leading edge of the paper P is not caught by the ridge 8n. Yes.

  As described above, the disc tray detection means 55 for detecting the disc tray 60 as the transported medium includes the detection lever 56 provided on the paper discharge receiving tray 8 and the detector main body 57 provided on the apparatus main body 2 side. And a detector 58. That is, when the paper discharge receiving tray 8 is in a position where the detection lever 56 can be detected by the detector main body 57 and the detector 58 (that is, the storage position), the disk tray detection means 55 is configured.

  That is, when the detection means is provided in the raised portion 8d of the paper discharge receiving tray 8, it is necessary to provide a signal line between the apparatus main body 2 and the raised portion 8d, but the paper discharge receiving tray 8 performs an advance / retreat operation. For this reason, there is a possibility that the signal line may be caught or disconnected due to the advance / retreat operation of the sheet receiving tray 8. However, as described above, the disc tray detection means 55 includes the detection lever 56 provided on the paper discharge receiving tray 8 and the detector main body 57 and the detector 58 provided on the apparatus main body 2 side. There is no need to provide a signal line between the apparatus main body 2 and the paper discharge receiving tray 8, and there is no possibility of problems such as catching or disconnection of the signal line.

  In the present embodiment, the raised portion 8d is provided in an area for supporting the paper P, the detection lever 56 is provided in the raised portion 8d, and the raised portion 8d has a tray guide surface. 8h is provided below the upper surface of the raised portion 8d, and an inclined guide surface 8c is formed to guide the leading edge of the discharged paper P over the raised portion 8d.

  That is, the raised portion 8d is disposed in the discharge area of the paper P, whereby the width of the paper discharge receiving tray 8d is not increased, and the smooth discharge of the paper P is hindered by the inclined guide surface 8c. There is nothing to do. Moreover, since the detection lever 56 is provided inside the raised portion 8d, the detection lever 56 can be arranged efficiently.

  An optical sensor is used in place of the detector main body 57 and the detector 58 constituting the disc tray detection means 55, the detection lever 56 is eliminated, and a reflector that can be detected by the optical sensor is provided on the disc tray 60. It is also good.

■■■ 3. Disc tray 60 and its detection operation ■■■■■■■■■■■■■■■■■
Next, the disc tray 60 and its detection operation will be described. First, the structure of the disc tray 60 will be described with reference to FIG. In FIG. 11, in order to show the positional relationship among the disc tray 60, the conveyance drive roller 24, the conveyance driven roller 25, and the discharge drive roller 31, these rollers are also illustrated.

  The disc tray 60 is a plate-like body formed entirely of a resin material, and is formed so that the optical disc D can be accommodated in the disc accommodating recess 60a. A convex portion 60b that engages with the central hole of the optical disc D is formed in the central portion of the disc accommodating concave portion 60a.

  The front end of the disc tray 60 (upper side in FIG. 11: the insertion side of the disc tray 60) is a first front end portion 60h that constitutes the most front end portion, a second front end portion 60j that is located on the rear end side from this, and It is comprised by the 3rd front-end | tip part 60k located in the back end side, and the 4th front-end | tip part 60m located in the back end side further from this.

  These front end portions have a shape (tapered shape) whose thickness decreases toward the front end side, so that they can smoothly enter between the transport driving roller 24 and the transport driven roller 25. Yes. Here, in the present embodiment, a plurality of roller support members 26 (indicated by reference numerals 26A to 26D in FIG. 11 are distinguished), the two roller support members 26B and 26C at the center are the roller supports on both sides thereof. The pressure contact force when the transport driven roller 25 is brought into pressure contact with the transport drive roller 24 is set to be smaller than that of the members 26A and 26D (biased by such a biasing means).

  Accordingly, when the leading end of the disc tray 60 once enters the lower side of the transport driven roller 5 provided in the width direction, a large resistance is generated when the disc tray 60 is inserted. Therefore, the front end of the disc tray 60 is the outer two transport driven rollers 25 among the four transport driven rollers 25 (supported by the roller support members 26B and 26C) urged with a relatively small load. The first tip portion 60h first enters the lower side. Next, the second tip end portion 60j enters the lower side of the two inner conveyance driven rollers 25.

Next, among the four transport driven rollers 25 (supported by the roller support members 26 </ b> A and 26 </ b> D) on both sides urged by a relatively large load, the lower side of the inner two transport driven rollers 25. The third tip portion 60k enters into. Next, the fourth tip end portion 60 m enters the lower side of the two outermost driven rollers 25.
As described above, when the disc tray 60 is inserted between the transport driven roller 25 and the transport driving roller 24, an excessive load is not generated.

  Next, a positioning line 60f is attached to the upper surface of the disc tray 60. When the user sets the disc tray 60 on the discharge receiving tray 8, the positioning line 60f is aligned with the front side edge 34b (FIG. 8) of the frame 34 constituting the base of the apparatus main body 2. This position is the recommended setting position of the disc tray 60, and the position Yt in FIGS. 15 to 17 is the position of the front side edge 34b of the frame 34. This position Yt is approximately the front end position of the paper discharge receiving tray 8.

FIG. 15 shows a state in which the disc tray 60 is set at the recommended setting position. In this state, the tip of the disc tray 60 does not enter between the transport driving roller 25 and the transport driven roller 24 as shown in the figure. .
15 to 17, the position Ys is a detection position of the disc tray 60 (hereinafter referred to as “tray detection position Ys”) by the tray position detecting means 55 described above, that is, the detection lever 56 in the paper discharge receiving tray 8. Is provided (more specifically, the position of the tray contact portion 56e). The position Yn indicates the rear end position of the disc tray 60 when the disc tray 60 is set at the recommended setting position.

  When receiving a print execution command for the optical disc D after the disc tray 60 is set, the control unit 40 performs a pull-in operation (upward conveying operation in FIG. 15) before starting printing.

  Here, a cutout portion 60c that can be detected by the disc tray detection means 55 is formed at one side end of the disc tray 60. Reference numeral k1 denotes the upper position of the cutout portion 60c from the tray detection position Ys. The distance to is shown. When the disc tray 60 is set at the recommended setting position, the tray detection position Ys is located upstream in the ejection direction (upper side in FIG. 15) from the notch 60c. Specifically, the “upper position” of the notch 60c is determined by the tray detection means 55 from the “present state” of the disc tray 60 when the disc tray 60 is pulled in from the state of FIG. This is the position where the change to the “none state” is detected.

  That is, when the disc tray 60 is set at the recommended setting position, the control unit 40 grasps that the disc tray 60 is actually set by the detection signal of the disc tray detecting means 55 indicating “present state”. it can. Then, the disk tray 60 is pulled in, and the tray detection means 55 detects the change of the disk tray 60 from the “present state” to the “absent state” at that time. 60 positions can be detected. Accordingly, it is not necessary to separately provide a means for detecting the position of the disk tray 60, the structure can be simplified, and the position can be detected by a slight pulling operation of the disk tray 60, which can contribute to an improvement in throughput.

  However, the user may set the disc tray 60 at a position greatly deviating from the recommended setting position. For example, FIG. 16 shows a state where the rear end of the disc tray 60 is inserted until it coincides with the position Yt, and the user has pushed the disc tray 60 as much as possible. When the control unit 40 pulls the disc tray 60 in order to detect the notch 60c from this state, the rear end of the disc tray 60 is disengaged from the tray detection position Ys, and the control unit 40 indicates that the “notch 60c is at the tray detection position. There is a risk of erroneous detection that “Ys has been reached.”

  Here, the pull-in amount of the disc tray 60 for first detecting the cutout portion 60c is a value (k1 + α) obtained by adding a predetermined margin α to the distance k1 in FIG. 15, but the erroneous detection is determined in advance. It does not occur if (k1 + α), which is the determined distance (conveyance amount), is smaller than the distance k2 in FIG. That is, even if the disc tray 60 is pulled in to detect the cutout portion 60c, the rear end of the disc tray 60 does not go upstream from the tray detection position Ys, thereby preventing the erroneous detection.

  However, in this case, even if the disk tray 60 is pulled in, the tray detection means 55 does not detect the change of the disk tray 60 from the “present state” to the “absent state”. Therefore, in such a case, the control unit 40 detects the notch 60c by transporting the disc tray 60 downstream in the discharge direction, that is, in the discharge direction (downward in FIG. 16). If the tray detection means 55 detects a change from the “present state” to the “absent state” of the disc tray 60 by this discharge operation, it can be determined that it is the notch 60 c. In order to determine that it is the notch 60c, the disc tray 60 may be further moved by a predetermined amount in the pull-in direction and the discharge direction to detect the notch 60c.

  As another example in which the user sets the disc tray 60 at a position deviating from the recommended setting position, there is an example in which the notch 60c is desired at the tray detection position Ys as shown in FIG. In this case, since the tray detection means 55 detects the “absence state” of the disc tray 60, the control unit 40 determines whether the cutout portion 60c is positioned at the tray detection position Ys or the disc tray 60 itself is not set. I can't figure out which one is.

  Therefore, in such a case, the control unit 40 conveys the disc tray 60 by a predetermined amount to the upstream side in the discharge direction, that is, the pull-in side. At this time, if the tray detection means 55 detects a change from the “no state” to the “presence state” of the disk tray 60, it can be determined that the “no state” before the tray is pulled in has detected the notch 60c. As a result, it is possible to execute an appropriate control operation, that is, a printing operation thereafter without erroneously detecting that the “no state” before the tray has been pulled in if the disc tray 60 itself is not set.

  The embodiments and control examples described above are merely examples, and it goes without saying that the present invention is not limited to these embodiments and control examples.
