  The printer described in Patent Document 1 executes processing that does not cause a problem even when the paper discharge tray is closed in advance, and until the printing is restarted after the error is cleared (after the paper discharge tray is opened by the user). Processing time is shortened.

  On the other hand, the paper discharge tray may be in a half-opened position in addition to a completely closed position. This half-opening posture may be a posture in which the paper discharge port is not completely closed, but is opened to some extent, that is, a posture in which paper discharge is possible, and a print job is performed only when the paper discharge tray is fully open. If executed, the convenience of the apparatus is lowered. For example, the user is forced to fully open the paper discharge tray even though the paper can be discharged. The printer described in Patent Document 1 does not consider such problems.

  Accordingly, the present invention has been made in view of such a situation, and an object thereof is to further improve convenience in a recording apparatus having a cover for opening and closing a paper discharge port.

  In order to solve the above problems, a recording apparatus according to the first aspect of the present invention includes a recording unit for recording on a medium, a discharge unit for discharging the medium, a cover for opening and closing the discharge unit, and the cover And detecting means for switching a detection state in an intermediate posture between a fully closed posture and a fully open posture and capable of discharging the medium from the discharge portion.

Is provided, so that, based on the detection state of the detection means, the medium discharge operation can be performed if the medium can be discharged even when the cover is not in the fully open position. It is possible to further improve convenience.

  According to a second aspect of the present invention, in the first aspect, the cover opens and closes the discharge portion by rotating about a rotation shaft, and the rotation shaft rotates from both side portions of the cover. A cam portion is formed on the rotating shaft formed in a protruding shape protruding in the axial direction and formed on one side portion of the cover, and the cam portion is detected by the detecting means as the cover rotates. It is characterized by changing the state.

  According to this aspect, the cam portion is formed on the rotation shaft of the cover, and the cam portion changes the detection state of the detection means as the cover rotates, so the detection state of the detection means is changed. The configuration can be simplified and the configuration can be reduced.

According to a third aspect of the present invention, in the second aspect, the rotation shaft formed on the one side portion of the cover is longer in length than the rotation shaft formed on the other side portion. Characterized by its long length.
According to this aspect, the rotation shaft (the rotation shaft on which the cam is formed) formed on one side of the cover is longer than the rotation shaft formed on the other side. Therefore, the degree of freedom of arrangement of the detection means that engages with the cam portion can be improved. For example, the detection means can be arranged at a position far from the base end side of the rotation shaft.

According to a fourth aspect of the present invention, in the third aspect, the tip of the long rotating shaft is formed in a tapered shape.
According to this aspect, since the tip of the long rotation shaft is formed in a taper shape, when the long rotation shaft is inserted into the housing during assembly of the product, it is smooth without being caught. Can be inserted into.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the discharge unit that discharges the medium from the discharge unit includes a discharge roller, and the control unit that controls the discharge roller detects information by the detection unit. Based on the above, when the cover is positioned closer to the fully closed position than the intermediate position, the discharge roller does not discharge the medium, and the cover is positioned between the intermediate position and the fully open position. In some cases, the medium is discharged by the discharge roller.

  According to this aspect, the control unit that controls the discharge roller that discharges the medium from the discharge unit is configured such that the cover is positioned between the intermediate position and the fully open position based on the detection information by the detection unit. In this case, since the medium is discharged by the discharge roller, even if the cover is not in the fully open posture, the medium discharge operation is executed, so that the convenience of the recording apparatus can be further improved. .

The outline of the printer 1 has been described above. Hereinafter, the open / close sensor 13 as a detecting unit for detecting the posture of the sheet receiving tray 9 will be described with reference to FIG.
As shown in FIG. 5, the sheet receiving tray 9 has protrusion-like turning shafts 10 and 11 projecting in the turning axis direction (x direction) on both side portions (both sides in the x direction). 10 and 11 are inserted into holes 17a and 17b (FIGS. 10A and 10B) formed in the casing 17 constituting the apparatus main body 2, respectively. This insertion is performed by bending the paper receiving tray 9. The sheet receiving tray 9 is made of a resin material so that it can be bent in this embodiment.

  The rotation shaft 11 is formed to be longer than the rotation shaft 10, and the longer rotation shaft 11 is first inserted into the hole 17b when inserted. Next, the sheet receiving tray 9 is bent and the rotating shaft 10 having a short length is inserted into the hole 17a. Since the tip of the rotating shaft 11 is formed in an inclined shape, the hooking when the rotating shaft 11 is inserted into the hole 17b is suppressed.

  Next, an open / close sensor 13 is provided on the long rotating shaft 10 side. The open / close sensor 13 includes a sensor main body 13a and a switch 13b. The switch 13b is pushed into the sensor main body 13a (FIGS. 4, 8, and 9) and is protruded from the sensor main body 13a (FIG. 6, FIG. 6). Fig. 7). The detection state of the sensor body 13a is switched depending on the state of the switch 13b. The control unit 6 (FIGS. 7 to 9) of the printer 1 determines the posture of the sheet receiving tray 9 based on a signal from the sensor body 13a.

  More specifically, a cam portion 11 a is formed on the rotating shaft 11 formed on one side portion of the sheet receiving tray 9. The switch 13b of the open / close sensor 13 faces the cam portion 11a, and the cam portion 11a pushes the switch 13b as the paper receiving tray 9 rotates. That is, the cam portion 11a changes the detection state of the open / close sensor 13.

  Hereinafter, the posture of the sheet receiving tray 9 when the cam portion 11a pushes down the switch 13b will be described with reference to FIGS. As shown in FIG. 7, when the sheet receiving tray 9 is in the fully closed position, the cam portion 11a is not engaged with the switch 13b (the switch 13b is not pushed in). Based on the state of the open / close sensor 13 at this time, the controller 6 determines that the sheet receiving tray 9 is in a fully closed position or a position close to the fully closed position, that is, a position in which the sheet cannot be discharged. Therefore, in this state, the control unit 6 does not discharge the paper. That is, the discharge drive roller 30 is not driven. Further, when a print execution command is received in this state, the control unit 6 displays an alert indicating that the paper receiving tray 9 is closed on the display unit 4.

  Next, when the sheet receiving tray 9 is in an intermediate position while moving from the fully closed position to the fully open position, the cam portion 11a is engaged with the switch 13b as shown in FIG. 8, that is, the switch 13b is pushed. This intermediate posture of the paper receiving tray 9 is a posture in which the paper can be discharged as shown by a two-dot chain line P (paper discharge locus) although it is not a fully open posture (half-open state). The cam portion 11a is formed so as to push in the switch 13b when the paper receiving tray 9 is in such a posture.

Based on the state of the open / close sensor 13 at this time, the control unit 6 determines that the paper receiving tray 9 has been opened to an angle at which paper can be discharged at least. Accordingly, in this state, the control unit 6 discharges the sheet. That is, the discharge drive roller 30 is driven.
FIG. 9 shows the fully open posture of the sheet receiving tray 9. Even when the sheet receiving tray 9 is in the fully open posture, the push of the switch 13b by the cam portion 11a is continued.

  As described above, the printer 1 according to the present invention includes the inkjet recording head 26 as a recording unit that performs recording on a sheet that is an example of a medium, the sheet discharge port 8 as a discharge unit that discharges a sheet, and the sheet discharge port 8.

An open / close sensor 13 is provided as detection means for switching.

  Accordingly, the paper discharge operation can be executed even when the paper receiving tray 9 is not in the fully open posture, and the convenience of the printer 1 can be further improved.

  Further, in this embodiment, the paper receiving tray 9 opens and closes the paper discharge port 8 by rotating about the rotating shafts 10 and 11, and the rotating shafts 10 and 11 rotate from both sides of the paper receiving tray 9. A cam portion 11 a is formed on a rotating shaft 11 formed in a protruding shape protruding in the direction of the moving axis and formed on one side of the paper receiving tray 9, and as the paper receiving tray 9 rotates, the cam portion 11 a. Changes the detection state of the open / close sensor 13. Therefore, the structure for changing the detection state of the open / close sensor 13 can be simplified and the structure can be reduced.

  In this embodiment, the rotation shaft 11 formed on one side portion of the sheet receiving tray 9 is longer than the rotation shaft 10 formed on the other side portion. It is possible to improve the degree of freedom of arrangement of the engaging opening / closing sensor 13. For example, the open / close sensor 13 can be disposed at a position far from the base end side of the rotation shaft 11 (leftward in FIG. 10A).

  In this embodiment, since the tip of the long rotation shaft 11 is tapered, the long rotation shaft 11 is inserted into the housing 17 (hole 17b) when the product is assembled. In this case, it can be smoothly inserted without being caught.

  In the present embodiment, the paper receiving tray 9 also serves as a tray for receiving the paper discharged from the paper discharge port 8, so that the number of parts can be reduced and the cost of the apparatus can be reduced.

  In this embodiment, the control unit 6 that controls the discharge drive roller 30 performs discharge drive when the posture of the paper receiving tray 9 is closer to the fully closed posture than the intermediate posture based on the detection information by the open / close sensor 13. When the sheet is not discharged by the roller 30 (FIG. 7) and the posture of the sheet receiving tray 9 is between the intermediate position and the fully open position (FIG. 8), the discharge drive roller 30 discharges the sheet.

  Therefore, even when the sheet receiving tray 9 is not in the fully open posture, the convenience of the recording apparatus can be further improved by executing the sheet discharging operation.

  The embodiment described above is an example, and various modifications are possible. For example, in the above-described embodiment, a small recording apparatus that takes portability into account has been described as an example, but a stationary recording apparatus may be used. In the above embodiment, an ink jet printer that performs recording by discharging liquid (ink) has been described as an example. However, the present invention can also be applied to other recording systems, for example, a thermal transfer recording apparatus.

  In the above embodiment, the open / close sensor 13 as a detecting means for detecting the posture of the paper receiving tray 9 is a so-called mechanical switch including the sensor main body 13 and the switch 13b. It may be a sensor.
