  Next, the paper conveyance path of the printer 1 will be described mainly with reference to FIGS. The printer 1 according to the present embodiment includes a lower tray 50 and an upper tray 53 at the bottom of the apparatus, and feeds recording sheets one by one from the lower tray 50 or the upper tray 53.

  The upper tray 53 is slidably displaceable between a feedable position (not shown) and a retracted position (FIGS. 4 to 6), and can be fed by receiving the power of a motor (not shown). Displace between position and retracted position. 4 to 6, the paper stored in the lower tray 50 is denoted by reference symbol P1, and the paper stored in the upper tray 53 is denoted by reference symbol P2. If not, say “paper P”). Further, the passage trajectory of the paper P1 sent out from the lower tray 50 is indicated by a broken line T1 (FIG. 6).

  A feeding roller (also referred to as a pickup roller) 10 that is rotationally driven by a motor (not shown) is provided on a swinging member 11 that swings about a rotating shaft 12, and the paper P <b> 1 accommodated in the lower tray 50. The uppermost sheet P or the uppermost sheet P2 accommodated in the upper tray 53 is rotated in contact with the uppermost sheet P2 to feed out the uppermost sheet P from each tray.

  In this embodiment, the rotating shaft 12 constitutes the swinging shaft of the swinging member 11 and rotates by receiving the power of a motor (not shown), thereby rotating the rotating shaft via a toothed wheel train (not shown). Power is transmitted from 12 to the feed roller 10. In this embodiment, the swing member 11 and the feeding roller 10 constitute a feeding unit 9 that feeds the paper P.

  Subsequently, a separation slope 16 is provided at a position facing the leading ends of the lower tray 50 and the upper tray 53 in the apparatus main body 2, and the leading edge of the paper P delivered from each tray is in contact with the separation slope 16. However, by proceeding downstream, the uppermost sheet P to be fed is separated from the subsequent sheet P.

  An intermediate roller 17 that is rotationally driven by a motor (not shown) is provided at the tip of the separating unit 14, and the sheet P is curved and reversed by the intermediate roller 17 and moves toward the front side of the apparatus. Reference numerals 19, 20, and 21 are driven rollers that can be driven and rotated. At least the paper P is nipped by the driven roller 19 and the intermediate roller 17, and is nipped by the driven roller 20 and the intermediate roller 17, and is downstream. Sent to the side.

  At the end of the intermediate roller 17, there are provided a transport driving roller 24 that is rotationally driven by a motor (not shown), and a transport driven roller 25 that is driven and rotated in contact with the transport driving roller 24. It is sent under the recording head 30.

  Subsequently, the recording head 30 for ejecting ink is provided at the bottom of the carriage 29, and the carriage 29 is driven by a motor (not shown) so as to reciprocate in the main scanning direction (the front and back directions in FIGS. 4 to 6).

  A support member 28 is provided at a position facing the recording head 30, and the support member 28 defines an interval between the paper P and the recording head 30. Further, on the downstream side of the support member 28, there is a discharge means (feed means) provided with a discharge drive roller 31 that is rotationally driven by a motor (not shown) and a discharge driven roller 32 that is driven to rotate in contact with the discharge drive roller 31. Is provided. The sheet P on which recording has been performed by the recording head 30 is discharged toward the above-described discharge receiving tray 8 by these rollers.

  The above is the description of the feeding path of the paper P sent out from the lower tray 50 or the upper tray 53. As described above, the printer 1 inserts the disc tray 60 on which the optical disc D is set from the front side of the apparatus. The optical disc D can be directly ink-jet recorded. When the disc tray 60 is inserted from the front side of the apparatus, the tip of the disc tray 60 comes into contact with the release roller 38.

  The release roller 38 is pivotally supported by a swinging member 37. The swinging member 37 is attached to a frame Assy 36 that supports the discharge driven roller 32 via the swinging shaft 37a in the clockwise direction of FIGS. And can be swung counterclockwise. Here, as shown in FIG. 6, when the swinging member 37 is in contact with the paper P that proceeds from the upstream side toward the downstream side in the medium discharge direction, it is allowed to be pushed up by the paper P. When the disc tray 60 is inserted from the downstream side in the discharge direction toward the upstream side, the swinging is restricted.

  On the other hand, the frame Assy 36 is provided so as to be displaceable in the vertical direction. Therefore, when the disc tray 60 is inserted, the swinging of the swinging member 37 is restricted, so that the disc tray 60 is interposed via the swinging member 37. The frame Assy 36 is pushed upward (FIG. 5). As a result, the discharge driven roller 32 is separated from the discharge drive roller 31, and the discharge driven roller 32 is not in contact with the optical disk D set on the disk tray 60. In this state, the release roller 38 receives the weight of the frame Assy 36, so the disc tray 60 is pressed toward the discharge drive roller 31 by the release roller 38, whereby the discharge drive roller 31 imparts a conveying force to the disc tray 60. To do.

  In addition, the roller support member 26 that supports the transport driven roller 25 on the upstream side of the discharge drive roller 31 is provided so as to be swingable about the swing shaft 26a, and the transport driven roller 25 by an urging means (not shown). Is urged in a direction in which it is pressed against the transport drive roller 24. When the disc tray 60 is sent to the upstream side, the tip of the disc tray 60 enters between the conveyance driving roller 24 and the conveyance driven roller 25 through the swinging of the roller support member 26, whereby the disc tray 60 is conveyed. 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.

  The above is the recording using the disc tray 60, but the printer 1 according to the present embodiment is also characterized in a paper feeding method when recording using the manual feed tray 7. As described above, the manual feed tray 7 is exposed by opening the manual feed cover 6 provided at the upper rear portion of the apparatus. 17 and 18 show a state in which the manual feed cover 6 is opened. As shown in the figure, edge guides 14a and 14b are provided at both ends of the manual feed tray 7, and these edge guides can be displaced according to the paper size. Is provided.

  A detection lever 15 is provided on the edge guide 14a side (not shown). The detection lever 15 is a detector constituting detection means (not shown) for detecting the open / closed state of the manual cover 6, and is provided so as to be engageable with a lever engaging portion 6 a formed on the manual cover 6. It has been. When the manual feed cover 6 is closed, the detection lever 15 is pushed downward by the lever engaging portion 6a, whereby the control unit (not shown) of the printer 1 detects the closed state of the manual feed cover 6. When the manual cover 6 is opened, the detection lever 15 is pushed upward by an unillustrated urging means, whereby the control unit detects the open state of the manual cover 6.

  When performing paper feeding using the manual feed cover 6, the user first operates the operation panel 5 to select the manual paper feed mode, and sets (inserts) the paper into the manual feed tray 7 in accordance with a message displayed on the panel. ). Thereafter, the user operates the operation panel 5 to instruct execution of recording, or instructs the execution of recording from a computer connected to the printer 1. A broken line in FIG. 19 indicates a sheet passage route when the manual feed tray 7 is used.

  By the way, when a sheet is set on the manual feed tray 7, the leading end of the sheet is nipped by the intermediate roller 17 and the driven roller 20. Here, when the user selects the manual feed mode on the operation panel 5, the control unit of the printer 1 moves a lock mechanism (not shown) for locking the carriage 29 in order to release the standby state. This locking mechanism has a common drive source with the intermediate roller 17, so if the user sets paper on the manual feed tray 7 before selecting the manual paper feed mode on the operation panel 5, the paper will be somewhat damaged. It will be sent downstream. As a result, there is a possibility that the cueing of the paper (positioning of the paper to the recording start position) cannot be performed accurately.

  Therefore, when the control unit detects that the sheet has entered the transport path when the manual paper feed mode is selected by the user, the control unit detects the rollers (the intermediate roller 17, the transport drive roller 24, the discharge drive) on the transport path. All the rollers 31) are driven to rotate in the forward direction, and the sheet is discharged to the sheet receiving tray 8. This prevents the paper from being cueing accurately. Note that when the user selects the manual paper feed mode, the paper intrusion into the paper conveyance path is provided in the vicinity of the upstream side of the conveyance driving roller 24 (may be in the vicinity of the downstream side). Is detected.

■■■ 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).

  The rack portion 8f is a rack that constitutes a rack and pinion mechanism, and a pinion gear 44 that constitutes the drive means 42 meshes therewith. 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 protruding position (first position: FIGS. 2, 6, 11, and 15). 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.

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.

  Each sensor senses a predetermined position of the paper discharge receiving tray 8 as the paper discharge receiving tray 8 moves. Each sensor is arranged so that the position of the sensing line at this time does not match in the width direction of the discharge receiving tray 8. Depending on the combination of the detection states of these two sensors, one of the three states, that is, whether the paper discharge receiving tray 8 is in the most protruding position, in the storage position, or in any of the positions, is determined. to decide.

  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 constituting a “first inclined portion” is formed on the upstream side of the raised portion 8d, and the raised portion 8d can be smoothly moved without being caught by the raised portion 8d. You can get over it.

  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 constituting a “second inclined portion” is formed downstream of the sheet receiving surface 8a in the central region (between the two raised portions 8d), and is positioned higher than the sheet receiving surface 8a. Since it is connected to the support surface 8j, the sheet having a width where both end portions do not climb over the raised portion 8d is prevented from falling from the sheet receiving tray 8 by the inclined guide surface 8b and the high position support surface 8j. Is done.

  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, and the height position is set to a position where the disc tray 60 can be supplied horizontally toward the transport path of the apparatus main body 2. Yes.

  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, as shown in FIG. 9, an escape portion 8 r that avoids the feeding means 9 is formed on the upstream side in the paper discharge direction (upper left side in FIG. 9) in the paper discharge receiving tray 8. The escape portion 8r is set so that its width (width in the paper width direction) h is slightly larger than the width of the swing member 11, that is, the swing member 11 can swing inside the escape portion 8r. Has been. Further, in the present embodiment, the feeding reference position in the paper width direction is set at the center of the paper, so that the escape portion 8r is formed substantially at the center in the paper width direction.

  The escape portion 8r has the following operational effects. That is, the paper discharge receiving tray 8 is provided so as to be housed inside the apparatus main body 2. However, when the feeding means 9 and the paper discharge receiving tray 8 are provided so as to overlap with each other in the state of being housed in the apparatus main body, It tends to cause an increase in size (especially an increase in dimension in the height direction).

  However, as described above, the discharge receiving tray 8 is provided with the escape portion 8r that avoids the feeding means 9, so that it is necessary to overlap the feeding means 9 and the discharge receiving tray 8 in the height direction of the apparatus. However, both can be overlapped in the height direction, and an increase in the height dimension of the apparatus can be suppressed.

  As described above, the discharge receiving tray 8 has a raised portion 8d on both downstream sides of the paper receiving surface 8a, and both ends of the paper (paper discharge) are formed on the raised portion 8d. The curl is formed on the sheet by climbing up both ends in the direction intersecting the direction (the sheet width direction). In FIG. 10, the sheet indicated by the reference symbol P ′ and the phantom line shows such a curled state, and both downstream end portions ride on the raised portion 8d, and in addition to this, the upstream center As the part slightly enters the escape part 8r, the paper is curled.

  As a result, it is possible to prevent the leading end of the sheet from protruding from the sheet receiving surface 8a and drooping, and eventually falling. In order to form the curl of the paper as shown in FIG. 8, the escape portion 8r is preferably formed at the center in the paper width direction, but the escape portion 8r is formed at the end in the paper width direction. Even in such a case, if the raised portions 8d are formed at both ends on the downstream side, it is possible to promote the formation of curl on the paper.

  Next, the relationship between the operation panel 5 and the paper receiving tray 8 will be described with reference to FIG. As already described, the operation panel 5 is provided at a position that interferes with the displacement (slide) region of the paper discharge receiving tray 8. Specifically, in a state where the operation panel 5 is in a fully closed state (first posture) or in a posture from the first posture between the fully closed state and the fully open state (second posture) (the storage position or The raised portion 8d of the paper discharge receiving tray 8 (at the most protruding position) is at a position overlapping the operation panel 5 in the apparatus height direction. That is, for example, when the discharge receiving tray 8 is displaced straight from the most protruding position to the storage position, the raised portion 8d is in a positional relationship in which it interferes with the lower end 5b of the operation panel 5.

  Therefore, for example, when the operation panel 5 is opened and the discharge receiving tray 8 is at the most protruding position and the operation panel 5 is closed by the user's hand (the state shown in FIG. 11), the discharge receiving tray 8 is in that state. When displaced toward the storage position, the raised portion 8d comes into contact with the lower end 5b of the operation panel 5, and there is a possibility that the paper discharge receiving tray 8 and the driving means 42 for moving it forward and backward are damaged. Further, there is a risk of causing damage on the operation panel 5 side.

  Accordingly, the discharge receiving tray 8 according to the present invention is configured such that the upstream side portion (indicated by reference numeral 8m) from the raised portion 8d is elastically deformable (hereinafter referred to as "elastic deformation portion 8m"). That is, as shown in FIG. 12, when the discharge receiving tray 8 is displaced from the most projecting position (first position) toward the storage position (second position), as shown in FIG. 12, the upstream side of the raised portion 8d. That is, the inclined guide surface 8 c constituting the “first inclined portion” contacts the lower end 5 b of the operation panel 5.

  At this time, since the paper discharge receiving tray 8 includes the elastic deformation portion 8m, the protruding portion 8d is displaced downward via the elastic deformation of the elastic deformation portion 8m as shown in FIG. The ridge-shaped part indicated by is shown before displacement). During this elastic deformation, the paper discharge receiving tray 8 is supported by the rail 34 a that supports the paper discharge receiving tray 8 and the pinion gear 44 in the frame 34.

In this way, the protruding portion 8d is displaced downward, so that the protruding portion 8d can easily pass under the operation panel 5 as shown in the change from FIG. 13 to FIG. 8 and the driving means 42 that moves the head back and forth can be prevented from being damaged, and the operation panel 5 can be prevented from being damaged.
Moreover, since the structure which can displace the protruding part 8d below is implement | achieved by the elastic deformation | transformation part 8m, the structure which can displace the protruding part 8d below can be constructed simply and at low cost. it can.

  When the paper discharge receiving tray 8 is pulled in, it is the inclined guide surface 8c that comes into contact with the lower end portion 5b of the operation panel 5 in the raised portion 8d. Therefore, the operation panel 5 extends along the inclined guide surface 8c. Can move relatively smoothly. That is, the raised portion 8d can be smoothly displaced downward without difficulty. Therefore, if a similar inclined guide surface is formed not only on the upstream side of the raised portion 8d but also on the downstream side, the raised portion 8d can be smoothly displaced downward smoothly even when the paper receiving tray 8 protrudes. it can. Such an inclined guide surface can be formed, for example, as a surface that is symmetrical to the inclined guide surface 8c in FIG.

  Further, in the present embodiment, the entire paper discharge receiving tray 8 is integrally formed of a resin material, and the elastic deformation portion 8m is a part (resin plate portion) of the elastic deformation portion 8m. In other words, the elastic deformation portion 8m can be formed of an independent member that is easily elastically deformed.

  Next, a second embodiment will be described with reference to FIGS. 15 and 16. The paper discharge receiving tray 8 ′ shown in FIGS. 15 and 16 includes protrusions 8 p and 8 q as “guided portions” on both sides. 15 and 16 show one side of the protrusions provided on both sides, the protrusions 8p and 8q are similarly provided on the other side.

  The protrusions 8p and 8q are provided at a predetermined interval in the sliding direction of the paper discharge receiving tray 8 ′. The protrusions 8p and 8q enter a guide groove (guide rail) 35 provided on the apparatus main body 2 side. It is in a state. In other words, the paper discharge receiving tray 8 'is supported by the guide groove 35 through the protrusions 8p and 8q and is guided in the displacement operation direction. The guide groove 35 can be provided in the frame 34 shown in FIG. 8, for example.

  The guide groove 35 has a recess 35a in the middle thereof. The concave portion 35a is provided at a position where it does not engage with the protrusion 8p in the entire displacement operation region of the paper discharge receiving tray 8 '. And this recessed part 35a is provided in the position which invites protrusion 8q, as shown in FIG. 16, when the protruding part 8d passes the lower side of the operation panel 5. FIG.

  For this reason, as shown in the change from FIG. 15 to FIG. 16, the protrusion 8q enters the recess 35a with the displacement operation of the discharge receiving tray 8 ′, and the discharge receiving tray 8 is entirely inclined. The raised portion 8d is displaced downward. As a result, the raised portion 8d can pass under the operation panel 5, and in particular, depending on the depth of the recess 35a, the raised portion 8d can pass under the operation panel 5 without contacting the operation panel 5. . As a result, it is possible to reliably prevent damage to the paper discharge receiving tray 8 and the driving means 42 that moves the paper tray 8 forward and backward, and it is also possible to reliably prevent damage to the operation panel 5 side.

  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.
