Description

  In the present invention, a placement surface on which a recording material is placed, a feeding roller that rotates when a rotational driving force of a driving force source is transmitted, and a placement surface or a part of the placement surface are displaced. A contact means for bringing the recording material placed on the placement surface into contact with the feeding roller, and a placement position in a direction crossing the feeding direction of the recording material placed on the placement surface. The present invention relates to an automatic feeding device including a regulating member to be regulated, and an electronic apparatus including the automatic feeding device.

  2. Description of the Related Art An electronic device including an automatic feeding device that automatically feeds recording materials such as paper one by one is known. For example, a recording apparatus such as an ink jet printer having means for executing recording of characters and images on the recording surface of the recording material, and reading characters and images recorded on the recording surface of the recording material that has been recorded A facsimile, a copier, a scanner device, and the like provided with the means. In an automatic feeding device mounted on such an electronic apparatus, a recording material is placed on a placing surface such as a feeding tray. The recording material placed on the placement surface is in contact with the feeding roller by means for displacing the placement surface or a member such as a hopper constituting a part of the placement surface during feeding. Become. Then, the recording material is fed into the electronic apparatus by rotating the feeding roller while the recording material is in contact with the feeding roller.

  In such an automatic feeding device, for example, an automatic feeding device provided with a regulating member that regulates the placement position of the recording material on the placement surface, such as a movable edge guide slidably supported by a hopper or the like. Is known (see, for example, Patent Document 1 or 2). By providing such a regulating member such as a movable edge guide, it is possible to feed the recording material from a state where it is placed at a predetermined position on the placement surface in accordance with the size of the recording material. Also, by providing a regulating member such as a movable edge guide, it is possible to regulate the posture of the recording material with respect to the feeding direction, so that the skew (feeding) of the recording material at the time of feeding, which causes a decrease in recording accuracy, is caused. (Inclination of the recording material with respect to the feeding direction) can be reduced.

  Here, as a support structure of the movable edge guide for the hopper or the like, for example, the movable edge guide is slidably supported by being hooked on the upper end of the hopper or the like, and provided on a portion that becomes a mounting surface of the hopper or the like. One in which a part of a movable edge guide is engaged with a guide groove is known (for example, see Patent Document 2 (particularly, paragraphs 0044, 0045, FIGS. 6, and 7 in the specification of Patent Document 2)).

Thus, by providing the guide groove of the movable edge guide on the mounting surface, the movable edge guide can be slid while being guided in the direction to be slid, so that the movable edge guide is slid more smoothly. It becomes possible. Further, the movable edge guide is slidably supported by a two-point support structure of at least an upper end of a hopper or the like and a guide groove. Accordingly, the movable edge guide can be supported more stably, and the possibility that the posture of the movable edge guide is inclined with respect to the feeding direction of the recording material can be reduced. Therefore, the placement position of the recording material can be regulated by bringing the movable edge guide into contact with the end portion of the recording material on the placement surface substantially parallel to the feeding direction. In other words, in this conventional automatic feeding apparatus, it is possible to regulate the recording material posture with respect to the feeding direction with high accuracy, so that the recording material at the time of feeding that causes a decrease in recording accuracy. Skew (inclination of the recording material with respect to the feeding direction) can be reduced.

  However, in the prior art described in Patent Document 2, by providing the guide groove of the movable edge guide on the recording surface of the recording material, the end of the recording material may be caught in the guide groove. . For example, in an electronic apparatus such as a recording apparatus, in order to convey a fed recording material to a predetermined recording start position, a conveying device while detecting the leading end position of the fed recording material with a sensor or the like In some cases, a so-called cueing operation is performed in which forward and reverse feeding of the recording material is alternately repeated. At that time, in the state where no other recording material is placed on the placement surface, depending on the size of the fed recording material, a part of the rear end of the fed recording material may be There is a possibility of getting caught in the guide groove on the mounting surface. In this case, the feeding operation of the fed recording material cannot be performed normally, and the fed recording material may be damaged or deformed.

  Such a problem does not occur unless, for example, the guide groove of the movable edge guide is provided on the mounting surface. However, since the guide groove is not provided on the mounting surface, it is difficult to smoothly slide the movable edge guide supported by the hopper or the like. Furthermore, the movable edge guide cannot be stably supported by a hopper or the like, and the posture of the movable edge guide may be inclined with respect to the recording material feeding direction.

  Also, for example, if the position of the guide groove on the mounting surface is set in consideration of each size of the recording material that can be handled and the reverse feed amount of the recording material during the cueing operation, It is also possible to provide a guide groove at a position where the rear end of the recording material is not caught. However, in recent years, since recording materials of various sizes have been distributed in recent years, it may be physically difficult to provide guide grooves at such positions. In addition, there is a possibility that the user may use a recording material other than the recording material that can be handled by the electronic device side, and considering the possibility of executing recording on a non-standard size recording material, In many cases, the problem cannot be solved only by adjusting the position of the guide groove.

  The present invention has been made in view of such a situation, and an object of the present invention is to realize an automatic feeding apparatus that is less likely to cause a recording material to be caught on the mounting surface.

  To achieve the above object, according to a first aspect of the present invention, there is provided a placement surface on which a recording material is placed, a feeding roller that is rotated by a rotational driving force transmitted from a driving force source, A contact means for displacing the placement surface or a part of the placement surface to bring the recording material placed on the placement surface into contact with the feeding roller; and the recording material on the placement surface A regulating member that regulates the mounting position of the automatic feeding device, wherein the regulating member is a device described in the previous section of the base of the automatic feeding device or the base of an electronic device on which the automatic feeding device is mounted. The portion facing the surface is supported so as to be displaceable along the placement surface, and is supported so as to be able to follow the displacement of the placement surface in contact with the placement surface. Is an automatic feeding device characterized by

  Thus, the regulating member that regulates the placement position of the recording material on the placement surface is not the placement surface, but the placement of the base of the automatic feeding device or the base of the electronic device on which the automatic feeding device is mounted. The portion facing the surface is supported so as to be displaceable along the placement surface. Accordingly, it is possible to smoothly displace the regulating member along the placing surface without providing a guide groove for the regulating member on the placing surface. Further, without providing the guide groove of the regulating member on the mounting surface, it is possible to stably support the regulating member and reduce the possibility that the attitude of the regulating member is inclined with respect to the recording material feeding direction. become. That is, since it is not necessary to provide the guide groove for the restricting member on the placement surface, it is possible to reduce the possibility that the recording material is caught on the placement surface.

  Further, since the regulating member is supported so as to be able to follow the displacement of the placement surface while being in contact with the placement surface, it is always placed on the placement surface regardless of the displacement position of the placement surface. Thus, the recording material is placed at a position where the placement position of the recording material can be regulated. That is, the recording material placed on the placement surface is appropriately regulated by the regulating member regardless of the displacement position of the placement surface. Therefore, the original function of the regulating member that regulates the placement position of the recording material on the placement surface is maintained regardless of the displacement position of the placement surface.

  As a result, according to the automatic feeding device described in the first aspect of the present invention, there can be obtained an effect that an automatic feeding device can be realized in which the recording material is less likely to be caught on the mounting surface.

According to a second aspect of the present invention, in the automatic feeding device according to the first aspect described above, the regulating member is urged toward the placement surface. Device.
Thus, since the regulating member is biased toward the placement surface, the state where the regulating member is in contact with the placement surface can be reliably maintained regardless of the displacement position of the placement surface.

According to a third aspect of the present invention, in the automatic feeding device according to the first aspect or the second aspect described above, the restriction member is caused to follow the displacement of the placement surface by the driving force of the driving force source. It is an automatic feeding device characterized by comprising a displacement means for displacing.
Thus, by providing the means for actively displacing the regulating member so as to follow the displacement of the placement surface, it is possible to reduce the displacement load when the placement surface is displaced. Moreover, the possibility that the displacement of the placement surface is hindered by the restriction member can be reduced.

According to a fourth aspect of the present invention, in the automatic feeding device according to any one of the first to third aspects described above, the member constituting the placement surface is supported to be swingable, and the restriction The member is an automatic feeding device characterized in that the member is supported so as to be displaceable along an arc trajectory centering on the swing axis of the member constituting the mounting surface.
In this way, when the regulating member is displaced along the arc locus centering on the swing axis of the mounting surface, the contact state between the regulating member and the mounting surface is always maintained regardless of the displacement position of the mounting surface. Can be kept constant.

According to a fifth aspect of the present invention, there is provided the automatic feeding apparatus according to any one of the first to fourth aspects described above, and means for executing recording on a recording material fed from the automatic feeding apparatus. , Is an electronic device.

The effect by the invention in any one of the aspects of 4 can be acquired.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First embodiment>
A first embodiment of the present invention will be described with reference to FIGS.

The ink jet printer 50 includes a transport driving roller 51 and a transport driven roller 52 as means for transporting the recording paper P as a “recording material” supported by the platen 53 in the transport direction Y. Further, the ink jet printer 50 includes a recording head 62 as means for performing recording by ejecting ink onto the recording surface of the recording paper P supported by the platen 53. Further, the ink jet printer 50 includes a discharge driving roller 54 and a discharge driven roller 55 as means for transporting and discharging the recording paper P after execution of recording in the transport direction Y.

  The transport driving roller 51 has a high friction coating on the surface, and rotates by receiving the rotational driving force of a transport motor (not shown). The transport driven roller 52 is pivotally supported so as to be driven to rotate, and is biased by a biasing means such as a spring (not shown) in contact with the outer peripheral surface of the transport driving roller 51. The recording paper P fed by the automatic feeding device 70 is sandwiched between the transport drive roller 51 and the transport driven roller 52 and is transported in the transport direction Y on the platen 53 by the drive rotation of the transport drive roller 51.

  The recording head 62 is disposed at the bottom of the carriage 61. A large number of ejection nozzles (not shown) for ejecting ink are disposed on the head surface of the recording head 62. The carriage 61 reciprocates in the width direction X (direction intersecting the transport direction Y) of the recording paper P while maintaining the state in which the head surface of the recording head 62 and the recording surface of the recording paper P on the platen 53 are substantially parallel. The carriage guide shaft 56 is supported so as to be movable. The carriage 61 is an endless belt (not shown) hung between a driving pulley (not shown) and a driven pulley (not shown) disposed on a rotating shaft of a carriage driving motor (not shown). Are coupled to each other, and the rotational driving force of the carriage driving motor is transmitted through the endless belt to reciprocate in the width direction X.

  The platen 53 has a large number of platen ribs (not shown) formed along the conveyance direction Y of the recording paper P. The recording paper P conveyed on the platen 53 is supported from the back side by the top surface of the platen rib. In the area of the recording paper P supported by the platen 53, dots are formed on the recording surface by ink ejection from the head surface of the recording head 62, and recording is performed. The distance between the head surface of the recording head 62 and the recording surface of the recording paper P is regulated to an appropriate distance by the top surface of the platen rib.

  The recording paper P conveyed on the platen 53 is configured to eject dots from the head surface of the recording head 62 to the recording surface of the recording paper P while the carriage 61 reciprocates in the width direction X, Recording on the recording surface is executed by alternately repeating the operation of conveying the sheet in the conveying direction Y by a predetermined rotation amount by driving rotation of the driving roller 51. The recording paper P after ink ejection is sandwiched between the discharge driving roller 54 and the discharge driven roller 55, conveyed in the conveyance direction Y by the driving rotation of the discharge driving roller 54, and discharged. A series of these recording controls is executed by a control device (not shown) having a microcomputer control circuit.

Next, a first embodiment of the automatic feeding device 70 according to the present invention will be described with reference to FIGS. 2 and 3 while continuing to refer to FIG.
FIG. 2 is a plan view of an essential part of a first embodiment of the automatic feeding apparatus 70 according to the present invention, and FIG. 3 is a side view of the essential part thereof.

  The automatic feeding device 70 includes a hopper 71, a feeding roller 72, a fixed edge guide 73, and a movable edge guide unit 10. The hopper 71 serving as the “loading surface” of the recording paper P is placed with the recording paper P stacked thereon. The hopper 71 is pivotally supported by a base body (not shown) of the automatic feeding device 70 so as to be swingable by a shaft portion 711. The feeding roller 72 is rotated by a rotational driving force of a feeding motor (not shown). The fixed edge guide 73 is fixed to one end side in the width direction X of the hopper 71, and one end side in the width direction X of the recording paper P placed on the hopper 71 comes into contact therewith.

  When the recording paper P is fed by the automatic feeding device 70, the hopper 71 is swung in the swinging direction indicated by the symbol A in conjunction with the rotation of the feeding roller 72 by a swinging mechanism (not shown). . As a result, the recording paper P placed on the hopper 71 comes into contact with and is pressed against the outer peripheral surface of the feeding roller 72 (contact means). The recording paper P is fed toward a portion where the transport driving roller 51 and the transport driven roller 52 come into contact with each other by the rotation of the feed roller 72. At this time, double feeding of the recording paper P is prevented by a known separation pad (not shown).

  The movable edge guide unit 10 is supported by a portion of the base of the inkjet printer 50 that faces the hopper 71. More specifically, the movable edge guide unit 10 is supported by the guide frame 11 constituting a part of the casing of the inkjet printer 50 so as to be displaceable in the width direction X. The movable edge guide unit 10 extends a part of the base body of the automatic feeding device 70 to a portion facing the hopper 71, and extends in the width direction X to a part of the base body of the extended automatic feeding apparatus 70. It may be supported so as to be displaceable.

  The movable edge guide unit 10 includes a supported portion 12, a movable edge guide 13, a movable edge guide accommodating portion 14, and a coil spring 15.

  The supported portion 12 is an L-shaped protrusion as shown. The movable edge guide unit 10 is supported by the supported portion 12 so as to be slidable in the width direction X while being hooked on the upper end of the guide frame 11. Further, a protrusion (not shown) is provided on the back of the movable edge guide unit 10, and a guide groove (not shown) formed substantially in parallel with the width direction X is provided on the guide frame 11. ing. The movable edge guide unit 10 is slidably engaged with the guide frame 11 in a state where the projection on the back is engaged with the guide groove of the guide frame 11.

  As a result, the movable edge guide 13 can be smoothly displaced in the width direction X along the hopper 71. Further, the movable edge guide 13 is stably supported on the guide frame 11 to reduce the possibility that the posture of the movable edge guide 13 is inclined with respect to the feeding direction of the recording paper P (the same direction as the transport direction Y). Is possible.

  The movable edge guide 13 as a “regulating member” is a member that regulates the placement position of the recording paper P placed on the hopper 71 in the width direction X. The recording position of the recording paper P placed on the hopper 71 is regulated according to the size of the recording paper P with the side surface of the fixed edge guide 73 as a reference surface. That is, the recording paper P placed on the hopper 71 is in a state where one end side in the width direction X is in contact with the fixed edge guide 73 serving as a reference surface and the other end side in the width direction X is in contact with the movable edge guide 13. The placement position in the width direction X is restricted. The movable edge guide 13 is supported by the movable edge guide unit 10 so as to be able to be displaced following the swinging displacement of the hopper 71 while being in contact with the hopper 71.

  More specifically, the movable edge guide 13 is an arc-shaped member in which a part of the fan-shaped tip is cut out, in other words, a part of a thick donut-shaped member is cut out. It is a shaped member. The movable edge guide 13 is supported so as to be displaceable along the inner wall surface of the movable edge guide accommodating portion 14 in a state where a part is accommodated in the movable edge guide accommodating portion 14. The inner wall surface of the movable edge guide accommodating portion 14 is formed in an arc shape along the outer shape of the movable edge guide 13, and the center point of the arc substantially coincides with the shaft portion 711 that becomes the swing axis of the hopper 71. ing. That is, the movable edge guide 13 is supported by the movable edge guide unit 10 so as to be displaceable along an arc locus centering on the swing axis of the hopper 71.

  Further, a coil spring 15 is contracted in the movable edge guide accommodating portion 14. The movable edge guide 13 is urged toward the hopper 71 by the spring force of the coil spring 15. When the hopper 71 swings in the direction indicated by the symbol A while being in contact with the hopper 71, the movable edge guide 13 follows the swinging displacement and is displaced in the direction indicated by the symbol B. In addition, without providing the coil spring 15, the movable edge guide 13 may be displaced following the swinging displacement of the hopper 71 in a state where the movable edge guide 13 is in contact with the hopper 71 by its own weight.

  The automatic feeding device 70 according to the present invention described above can smoothly displace the movable edge guide 13 in the width direction X along the hopper 71 without providing the hopper 71 with the guide groove of the movable edge guide 13. become. Further, without providing the guide groove of the movable edge guide 13 in the hopper 71, there is a possibility that the movable edge guide 13 is stably supported and the posture of the movable edge guide 13 is inclined with respect to the feeding direction of the recording paper P. It becomes possible to reduce. That is, since it is not necessary to provide the guide groove of the movable edge guide 13 in the hopper 71, the possibility that the recording paper P is caught on the hopper 71 can be reduced.

  Further, the movable edge guide 13 is supported so as to be able to follow the oscillating displacement of the hopper 71 while being in contact with the hopper 71, so that the movable edge guide 13 is always attached to the hopper 71 regardless of the oscillating displacement position of the hopper 71. The recording paper P is placed at a position where the placement position of the recording paper P can be regulated. That is, the placement position of the recording paper P placed on the hopper 71 is appropriately regulated by the movable edge guide 13 regardless of the swing displacement position of the hopper 71. Therefore, regardless of the displacement position of the hopper 71, the original function of the movable edge guide 13 that regulates the placement position of the recording paper P placed on the hopper 71 is maintained.

  Further, in the automatic feeding device 70 according to the present invention, it is preferable that the movable edge guide 13 is urged toward the hopper 71 by the spring force of the coil spring 15 or the like as in the first embodiment. Thereby, regardless of the swing displacement position of the hopper 71, the state in which the movable edge guide 13 is in contact with the hopper 71 can be reliably maintained. For example, the possibility that the movable edge guide 13 is temporarily separated from the hopper 71 when the hopper 71 is displaced can be reduced. Further, it is possible to reduce a possibility that a part of the recording paper P placed on the hopper 71 enters the gap between the hopper 71 and the movable edge guide 13.

  Furthermore, in the automatic feeding device 70 according to the present invention, when the hopper 71 constituting the “mounting surface” is supported so as to be swingable as in the first embodiment, the movable edge guide 13 is It is preferably supported so as to be displaceable along an arc trajectory centered on the swing axis of the hopper 71. Accordingly, the contact state between the movable edge guide 13 and the hopper 71 can always be kept constant regardless of the swing displacement position of the hopper 71. For example, regardless of the swing displacement position of the hopper 71, it is possible to maintain a state in which the end surface of the movable edge guide 13 is in surface contact with the hopper 71.

<Second embodiment>
Next, a second embodiment of the present invention will be described with reference to FIGS.

FIG. 4 is a side view of an essential part of a second embodiment of the ink jet printer 50 according to the present invention. FIG. 5 is a side view of an essential part of the second embodiment of the automatic feeder 70 according to the present invention.
The schematic configuration of the ink jet printer 50 is the same as that of the first embodiment, and a description thereof will be omitted. Further, the automatic feeding device 70 is the same as that of the first embodiment except for the structure of the movable edge guide unit 10, and the description thereof is omitted.

  The movable edge guide unit 10 of the second embodiment has a supported portion 12, a swing shaft portion 16, and a movable edge guide 17. The movable edge guide unit 10 is supported so as to be slidable in the width direction X in a state of being hooked on the upper end of the guide frame 11 by the supported portion 12 as in the first embodiment. Similarly to the first embodiment, the movable edge guide unit 10 is slidably engaged with the guide frame 11 in a state where the protrusion on the back is engaged with the guide groove of the guide frame 11.

  The movable edge guide 17 is pivotally supported by the movable edge guide unit 10 so as to be swingable about the swing shaft portion 16 as a swing shaft. As shown in the figure, the movable edge guide 17 is a member having a shape like a fan-shaped eccentric cam in which the distance from the swinging shaft portion 16 to the outer peripheral surface is gradually reduced, and the outer peripheral surface abuts against the hopper 71 by its own weight. It touches. The movable edge guide 17 swings in the direction indicated by C so that the outer peripheral surface is pushed up by the hopper 71 while the hopper 71 swings in the swinging direction indicated by reference A while being in sliding contact with the hopper 71. To do. That is, the movable edge guide 17 is supported so as to be able to swing and displace following the swinging displacement of the hopper 71 while being in contact with the hopper 71.

  In the automatic feeding device 70 according to the second embodiment described above, it is not necessary to provide the guide groove of the movable edge guide 17 in the hopper 71 as in the first embodiment, so that the recording paper P may be caught on the hopper 71. Can be reduced. Further, since the movable edge guide 17 is supported so as to be able to oscillate while following the oscillating displacement of the hopper 71 in a state where it is in contact with the hopper 71, the hopper 71 is always irrelevant to the oscillating displacement position of the hopper 71. The recording paper P placed on 71 is placed at a position where the placement position of the recording paper P can be regulated. Therefore, regardless of the displacement position of the hopper 71, the original function of the movable edge guide 17 that regulates the placement position of the recording paper P placed on the hopper 71 is maintained.

The thing provided with the means to displace so that a dynamic displacement may be followed is mentioned. By providing such means, the displacement load when the hopper 71 is oscillated and displaced can be reduced. Further, it is possible to reduce the possibility that the swing displacement of the hopper 71 is hindered by the movable edge guide 13 or the movable edge guide 17.

  Further, in the first embodiment or the second embodiment described above, the automatic feeding device 70 that restricts the placement position with respect to one end side in the width direction X of the recording paper P has been described as an example. The present invention can also be implemented in an automatic feeding device that regulates the placement position with the center position in the width direction X as a reference. In this case, another movable edge guide unit 10 is provided in place of the fixed edge guide 73, and both end positions in the width direction X of the recording paper P placed on the hopper 71 by the two movable edge guide units 10 are set.
