Description

  The present invention relates to a recording apparatus.

  In recent years, compact recording devices having a portable size have become widespread. In general, such a recording apparatus is designed so that the operation buttons and the discharge outlet of the recording medium do not appear on the exterior when not in use.

For example, the sheet feeding tray also serves as a cover for the upper surface portion on which operation buttons and the like are arranged, and when the recording apparatus is not used, the operation buttons can be covered by closing the sheet feeding tray. It can be opened and closed. The discharge tray also serves as a cover for the discharge outlet of the recording medium, and can be opened and closed so that the discharge outlet can be covered by closing the discharge tray when the recording apparatus is not used. ing.
The closed paper feed tray and paper discharge tray are designed to constitute a part of the appearance of the recording apparatus.

On the other hand, when the recording apparatus is used, recording starts with the paper tray and the paper discharge tray that are opened and closed open.
However, for example, if the user forgets to open the paper discharge tray or the recording paper tray is closed for some reason after opening the paper discharge tray and starting recording, the paper discharge tray remains closed. A recording operation may be performed. If the paper discharge tray is closed during recording, the recording medium after recording will be jammed in the recording apparatus.

  In order to solve this problem, Patent Document 1 discloses a recording apparatus configured to open a paper discharge port cover 804 in conjunction with opening of the paper supply cover 803.

JP 2004-122719 A

  However, for example, when the discharge port cover 804 is once opened in conjunction with the paper supply cover 803 and recording is started, the discharge port cover 804 is closed by the user, or a person or an object collides with it. In some cases, the discharge port cover 804 may be closed. In this case, the recording medium is still clogged in the recording apparatus.

  Accordingly, an object of the present invention is to reliably prevent an opening / closing portion such as a discharge port cover used in an opened state during recording from being closed during the recording.

  In order to solve the above-described problem, a recording apparatus according to a first aspect of the present invention includes a recording head for recording on a medium, and includes a carriage that reciprocates in a predetermined direction, an opening / closing part that opens and closes, and the opening / closing part is closed. A restricting portion for restricting this, and the restricting portion performs a restricting operation by using a movement of the carriage as a trigger from a home position where the carriage is located at the time of non-recording.

The opening / closing section provided in the recording apparatus may be closed when not in use, and may need to be opened during use (recording). For example, examples of such an opening / closing unit include a paper discharge tray and a paper feed tray that are opened and closed.
According to this aspect, since the carriage is moved from a home position (hereinafter sometimes referred to as HP) where the carriage is located during non-recording, the restriction portion performs the restriction operation. It is possible to restrict the opening / closing portion from being closed at the time of recording, which is a state of moving from the home position. Therefore, it is possible to prevent recording while the opening / closing part is closed.

  For example, when the opening / closing unit is a paper discharge tray that discharges a medium such as recording paper, it is prevented that recording is performed in a state where the paper discharge tray is closed. It is possible to prevent the medium from being jammed in the recording apparatus.

  The recording apparatus according to a second aspect of the present invention is the recording apparatus according to the first aspect, wherein the restricting portion is located at a first position that does not restrict the opening / closing portion from being closed when the carriage is located at a home position. When the carriage moves from the home position, the carriage is configured to advance and retract so as to advance to a second position that restricts the opening / closing portion from closing.

  According to this aspect, the configuration can be simplified and the effect of the first aspect can be obtained.

  The recording apparatus according to a third aspect of the present invention is characterized in that, in the second aspect, the advancing / retreating direction of the restricting portion is a reciprocating direction of the carriage.

According to this aspect, since the direction of the forward / backward movement of the restricting portion is the same as the reciprocating direction of the carriage, the movement of the carriage reciprocating and the movement of the restricting portion of the restricting portion are machined. Can be easily realized.
It should be noted that “the forward / backward direction of the restriction portion” and “the reciprocating direction of the carriage” are “same” are not limited to the same, that is, completely parallel. The movement of the carriage may be substantially the same as long as it can be interlocked by a mechanical configuration that directly transmits the movement of the reciprocating movement to the movement of the restricting portion.

  A recording apparatus according to a fourth aspect of the present invention is the recording apparatus according to the third aspect, further comprising a biasing member that biases the restricting portion in a direction to advance to the second position, and the restricting portion includes the carriage. Is moved to the first position together with the carriage against the urging force of the urging member when moving to the home position.

According to this aspect, when the carriage moves to the home position, the restricting portion moves to the first position integrally with the carriage against the urging force of the urging member. That is, it is located at the first position while being pushed by the carriage.
On the other hand, when the carriage moves from the home position to the recording area and performs recording, the carriage moves away from the restricting portion, and the restricting portion advances into the opening / closing region of the opening / closing portion by the urging force of the urging member. .

  This makes it possible to link the reciprocating movement of the carriage and the forward / backward movement of the restricting portion with a simple mechanical configuration without applying a load to the carriage during recording. Further, since no load is applied to the carriage during recording, it is possible to suppress a decrease in quietness during recording.

  The recording apparatus according to a fifth aspect of the present invention is the recording apparatus according to the fourth aspect, wherein the restricting portion includes a moving member that moves in the forward / backward direction, and a holding member that holds the moving member movably in the forward / backward direction. The urging member is a tension spring provided between the moving member and the holding member.

  According to this aspect, the restriction portion is configured by the moving member, the holding member, and the tension spring, and the same effect as in the fourth aspect can be obtained.

  The recording apparatus according to a sixth aspect of the present invention is the recording apparatus according to any one of the third to fifth aspects, wherein the restriction portion is It is provided with an inclined surface that moves the opening / closing part that is in the closed state in the opening direction when the restricting part advances.

  According to this aspect, when the restricting part advances with respect to the closed opening / closing part, the opening / closing part can be moved in the opening direction by the inclined surface. Thus, even when recording is started with the opening / closing portion closed, the opening / closing portion can be automatically opened.

Between the recording head 21 provided on the carriage 11 and a platen (not shown), the medium is transported in the transport direction (−Y direction) by a predetermined transport amount, and the recording head 21 is reciprocated once in the X-axis direction. Recording is performed on the medium by repeating the operation of ejecting ink from the recording head 21 during the movement. In the non-recording state, the carriage 11 is configured to be positioned at the home position on the end side on the + X direction side.
Reference numeral 9 denotes an opening cover that covers an opening continuous with the inside of the main body 2.

  When the recording apparatus 1 is not used, the upper surface cover 3 covers the entire upper surface part 5 of the main body 2 as shown in FIG. 1 and supports the medium supplied to the medium supply unit 6 when the recording apparatus 1 is used, that is, during recording. Functions as a paper feed tray.

A medium discharge unit 10 for discharging the medium after recording is provided on the side surface of the main body 2 in FIG. The medium discharge unit 10 is provided at a position recessed from the front surface of the main body 2. When the recording apparatus 1 is not used, the paper discharge cover 4 is closed as a cover of the medium discharge unit 10 as shown in FIG. 1, and there is almost no step between the front surface of the main body 2 and the paper discharge cover 4. That is, it is configured to be flush with each other.
The paper discharge cover 4 functions as a paper discharge tray that supports the medium discharged from the medium discharge unit 10 when the recording apparatus 1 is used, that is, during recording.

  Here, the recording apparatus 1 according to the present exemplary embodiment includes a regulation unit 12 that regulates the closing of the discharge cover 4 that is an opening / closing unit that opens and closes with respect to the main body 2. The restricting unit 12 will be described in more detail with reference to an enlarged view of a main part of the recording apparatus 1 of the present embodiment.

  FIGS. 3A and 3B are perspective views showing the restricting portion 12 according to an embodiment of the present invention, in which FIG. 3A is a state when is located at the first position, and FIG. 3B is a state where the second portion is advanced to the second position. It is. FIG. 4 is an enlarged view of a main part of the recording apparatus 1 according to an embodiment of the present invention. FIG. 4A is a diagram illustrating a discharge cover 4 in which the carriage 11 is located at the HP and the regulating part 12 is at the first position. (B) is a state in which the carriage 11 has moved from HP, the restricting portion 12 has advanced to the second position, and the paper discharge cover 4 has moved in the opening direction. FIGS. 5A and 5B are diagrams illustrating a state when the restriction unit 12 operates in the recording apparatus 1 according to the embodiment of the invention. FIG. 5A illustrates a state where the discharge cover 4 is closed, and FIG. 12 is a state in which the paper discharge cover 4 is opened by the regulating operation 12. FIG. 6 is a perspective view showing a slider 13 as a moving member constituting the restricting portion 12 shown in FIG. FIG. 7 is an enlarged view of a main part of the carriage 11 of the recording apparatus 1 according to the embodiment of the present invention.

  In the recording apparatus 1, the restricting unit 12 is located at a first position where the closing of the paper discharge cover 4 is not restricted when the carriage 11 is in the home position. When the carriage 11 moves from the home position, the paper discharge is performed. It is characterized in that it is configured to advance to a second position that restricts the closing of the cover 4. That is, the restricting operation by the restricting unit 12 is performed using the movement of the carriage 11 from the home position as a trigger.

First, a configuration in which the restricting unit 12 moves back and forth will be described with reference to the drawings.
As shown in FIGS. 3A and 3B, the restricting portion 12 includes a slider 13 as a moving member, and a holder 14 as a holding member that holds the slider 13 so as to be movable back and forth in the X-axis direction in the drawing. And a tension spring 15.

The holder 14 includes a screw hole 19 and holds the slider 13 in a state of being fixed to the inside of the main body 2 with a screw 20 as shown in FIGS. 4A and 4B, and moves. The slider 13 is provided so as to advance and retreat in the reciprocating direction of the carriage 11, that is, in the X-axis direction.
In the following, the movement of the slider 13 constituting the restricting portion 12 in the −X direction is referred to as advance, and the movement in the + X direction is referred to as retreat.

  Both ends of the tension spring 15 are supported by a spring support portion 17 on the slider 13 side and a spring support portion 18 on the holder 14 side. When a force for extending the tension spring 15 is not applied, the slider 13 is urged to advance toward the −X direction side by the tension force of the tension spring 15 [FIG. 3B]. On the other hand, when the tension spring 15 is extended to the + X side against the pulling force [FIG. 3A], the slider 13 moves backward in the + X direction side.

Here, the slider 13 that constitutes the restricting portion 12 is a member that restricts the closing of the paper discharge cover 4 in contact with the paper discharge cover 4 that is in the closed state or the closed state.
Further, the slider 13 includes an inclined surface 16 as an action part that restricts the paper discharge cover 4 from being substantially closed by contacting the paper discharge cover 4.
FIG. 4A shows a state where the carriage 11 is at the home position. At this time, the inclined surface 16 of the slider 13 is located at a position (first position) where the closing of the discharge cover 4 is not restricted. When the slider 13 is in the first position, the inclined surface 16 and the paper discharge cover 4 are not in contact with each other. Therefore, the paper discharge cover 4 can be closed.

On the other hand, FIG. 4B shows a state in which the carriage 11 has moved in the −X direction from the home position. At this time, the inclined surface 16 of the slider 13 is located at a position (second position) that restricts the discharge cover 4 from being closed.
Specifically, the second position is in an area between the open position and the closed position of the paper discharge cover 4 (hereinafter referred to as an open / close area). Since the inclined surface 16 contacts the paper discharge cover 4 at the second position in the open / close region, the paper discharge cover 4 cannot be closed. Therefore, it is possible to prevent the discharge cover 4 from being closed.

The slider 13 advances to the second position in the state of FIG. 3B in which the slider 13 has advanced to the −X direction side by the pulling force of the tension spring 15, and the tension spring 15 resists the pulling force to the + X side. In the state of FIG. 3 (A) extended to the first position, the first position is retracted.
The slider 13 includes a contact portion 23 (FIG. 6). When the carriage 11 moves from the recording area side to the home position side (+ X direction), the contact portion 23 is the contact portion 22 (see FIG. 6) on the carriage 11 side. 7), and is configured to move backward with the carriage 11 in the + X direction. That is, the slider 13 is positioned at the second position while being pushed by the carriage 11 that moves to the home position [state in FIG. 4A].

  On the other hand, when the carriage 11 moves from the home position to the recording area side (−X direction), the contact portion 22 on the carriage 11 side is separated from the contact portion 23 of the slider 13. As a result, the tension spring 15 becomes free, and the slider 13 moves to the −X direction side by the pulling force and advances to the second position [states of FIGS. 3B and 4B].

  With the above-described configuration, the carriage 11 during recording can be linked to the reciprocating movement of the carriage 11 and the forward / backward movement of the restricting portion 12 with a simple mechanical configuration without applying a load. Further, since no load is applied to the carriage 11 during recording, quietness during recording can be ensured.

  In the above description, the restricting portion 12 is urged in the direction to advance to the second position by the tension spring 15 provided between the slider 13 and the holder 14. For example, the + X axis of the slider 13 It is good also as a structure which provides a coil spring in the side and pushes out with respect to the advancing direction with the spring force of a coil spring. Also in this case, the restricting portion 12 can be configured to move to the first position integrally with the carriage 11 against the urging force of the coil spring.

Further, in the slider 13 of the restricting portion 12, when the recording is started with the paper discharge cover 4 being closed because the inclined surface 16 is formed with a portion that restricts contact and closing with the paper discharge cover 4 Furthermore, when the carriage 11 moves from the home position to the recording area and the slider 13 as the restricting portion 12 advances, the closed paper discharge cover 4 can be moved in the opening direction.
As shown in FIGS. 3 and 4, the inclined surface 16 has a narrower width at the front end side of the slider 13 in contact with the paper discharge cover 4 with respect to the Y-axis direction intersecting the X-axis direction that is the advancing and retreating direction. 13 is formed so that the width increases toward the paper discharge cover 4 side (−Y direction) as it goes to the + X direction side.

  When the slider 13 (the restricting portion 12) advances to the closed paper discharge cover 4, the rib 25 of the paper discharge cover 4 contacts the inclined surface 16 of the slider 13, and the paper discharge cover 4 moves in the -Y direction. Guided. As a result, the paper discharge cover 4 can be moved in the opening direction.

Here, the paper discharge cover 4 of the recording apparatus 1 includes, for example, a magnetic body (not shown) provided on the inner side of the paper discharge cover 4 (side facing the main body 2) and the paper discharge cover 4 side on the main body 2 side. When closed, a magnet (not shown) provided so as to correspond to the magnetic body is magnetically attached so that the discharge cover 4 is held in the main body 2 in a closed state. The closed paper discharge cover 4 as shown in FIGS. 4A and 5A is moved in the opening direction as shown in FIG. When the magnetic adhesion is released, the paper discharge cover 4 is automatically fully opened as shown in FIG.
Therefore, even if the recording is started with the paper discharge cover 4 closed, the paper discharge cover 4 can be automatically opened.

  In addition, the structure hold | maintained at the main body 2 in the state in which the paper discharge cover 4 was closed is not restricted to the magnetic attachment structure mentioned above. For example, it is possible to hold the closed paper discharge cover 4 on the main body 2 by providing a protrusion on the inner side on the paper discharge cover 4 side and engaging the protrusion with an engaging portion provided on the main body 2 side.

According to the recording apparatus 1 described in the present embodiment described above, the regulating operation is performed by the regulating unit 12 using the movement of the carriage 11 from the home position as a trigger. Therefore, the discharge cover 4 can be reliably opened during recording. it can. In addition, during recording, the restricting unit 12 has always advanced to the second position for restricting the closing of the paper discharge cover 4, so that even if the paper discharge cover 4 is intentionally closed during recording, it is closed. I can't. Accordingly, it is possible to maintain the state in which the paper discharge cover 4 is opened during recording.
Thus, it is possible to reliably prevent the paper discharge cover 4 from being closed during recording and the recording medium to be jammed in the recording apparatus 1.

Further, since the restricting portion 12 is configured using the slider 13, the holder 14, and the tension spring 15, the restricting portion 12 can be simply configured and can be provided at low cost and in a small space.
Further, since the operation of the restricting portion 12 is controlled by the mechanical configuration in conjunction with the reciprocating movement of the carriage 11, it is not necessary to provide a dedicated sequence for opening the paper discharge cover 4.

  In this embodiment, the case where the advancing / retreating direction of the restricting portion 12 is the reciprocating direction of the carriage 11 has been described. For example, a direction intersecting the reciprocating direction of the carriage 11 with respect to the similar discharge cover 4 For example, the restriction unit 12 may be configured to restrict the discharge cover 4 from closing and retreating in the Y-axis direction. Further, the restricting portion 12 can be provided for the upper surface cover 3 whose opening / closing portion is used as a paper feed tray. In that case, for example, a configuration may be adopted in which a restricting portion that advances and retreats in the Z-axis direction is provided on the upper surface portion 5 of the main body 2.

  Further, when the advancing / retreating direction of the restricting portion 12 is different from the reciprocating direction of the carriage 11, in order to link the movement of the carriage 11 and the movement of the restricting portion 12 by a mechanical configuration, the direction of the moving direction is changed by a cam, a pinion or the like It is necessary to change the configuration, and the configuration becomes complicated as the number of components increases. In such a case, the movement of the carriage 2 from the home position may be detected by a sensor or the like, and the restriction unit 12 may be advanced or retracted by sequence control using the movement as a trigger.

  It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
