  That is, the sensor carriage 33 scans the document placed on the document table glass 31 by moving in the main scanning direction (left-right direction in FIG. 3) during reading without using the automatic document feeder 1, but the automatic document At the time of reading using the conveyance device 1, scanning is performed by stopping at the reading position Y1 and moving the document side.

  On the downstream side of the reading position Y1, there is provided a document discharge means composed of a discharge driving roller 13 driven by a motor (not shown) and a driven roller 14 driven to rotate in contact therewith. The finished document is discharged toward the document receiving means 13 outside the medium conveyance path by these rollers.

The above is the general configuration of the automatic document feeder 1, and the document support 20 and the document receiving means 13 will be described in detail below.
The document receiving means 13 for receiving the discharged document is provided on the downstream side in the document discharge direction from the first document receiving portion 24 forming the first document receiving surface 24a and the first document receiving member, and supports the document. And a second document receiving portion 26 that forms a second document receiving surface 26a.

  The first document receiving portion 24 is in a first state in which the first document receiving surface 24a is connected to the second document receiving surface 26a to form a smooth and external device surface (FIGS. 1, 4, 6, and FIG. 8) and the downstream end of the first document receiving surface 24a and the upstream end of the second document receiving surface 26a in a second state (FIGS. 2, 5, 7, and 9). ) And can be switched. In this specification, the term “connect” between the first document receiving surface 24a and the second document receiving surface 26a means that the level difference formed between the two surfaces is relatively small compared to the second state. It is not necessarily meant to be strictly flush, and includes a mode in which some steps are formed.

  The first document receiving portion 24 is provided so as to be swingable about a swing shaft 24b (see FIGS. 8 and 9), and is switched between the first state and the second state by swinging. It has become.

  When the first document receiver 24 is in the first state, the document discharge port (indicated by reference numeral 15 in FIG. 5) is closed by the first document receiver 24 as shown in FIG. When the first document receiver 24 is in the second state, the document discharge port 15 is opened as shown in FIG.

  On the other hand, the document support 20 that supports the document before feeding is rotatably supported by pivot shafts 20a at both ends being supported by bearings 1d formed on the upper housing 1a (see FIG. 10) Open position (FIGS. 2, 5, 7, and 9) capable of supporting the original by rotating, and closed position (FIGS. 1, 4, 6, and 8) constituting the appearance of the apparatus. ) And can be switched.

  In the closed position, the document support 20 has an upper surface connected to the first document receiving surface 24a, for example, as shown in FIG. 4 to 9, the rotation shaft 20a of the document support 20 is not shown in the drawing in position, and is therefore indicated by a point as a position indicating the rotation center.

  The document support 20 and the first document receiving portion 24 described above are configured to operate in conjunction with each other by engaging via a link member 28 (FIGS. 6 to 9), more specifically. When the document support 20 is in the closed state, the first document receiver 24 takes the first state, and when the document support 20 is opened from this state, the first document receiver 24 is switched from the first state to the second state. It is like.

  The link member 28 is provided on the document support 20 via a swing shaft 28a provided at a position slightly deviated from the rotation shaft 20a of the document support 20, and as the document support 20 rotates, The position and posture of the distal end side are changed by climbing (or descending) on a guide slope 1c provided in the lower housing 1b. In this embodiment, the link members 28 are provided on both sides of the document support 20 in the width direction. However, the link members 28 may be provided only on one side in the width direction.

  A cam groove 28b is formed on the distal end side of the link member 28, and a boss 24d (functioning as a cam follower) formed in the cam groove 28b at a position away from the rotation shaft 24b in the first document receiving portion 24. ) Is loosely inserted. Accordingly, when the position and posture of the link member 28 change as the document support 20 rotates, the boss 24d moves in the cam groove 28b, and accordingly, the first document receiving portion 24 is centered on the swing shaft 24b. The first document receiving portion 24 switches between the first state (FIG. 6) and the second state (FIG. 7).

  Note that a constrained portion 28c is formed at a position different from the position where the cam groove 28b is provided in the link member 28, as shown in FIGS. It can move along a regulating surface 24c formed in the document receiving portion 24.

  When the first document receiver 24 is in the first state (FIG. 8), the first document receiver 24 is moved from the first state to the second state by the restriction surface 24c getting on the restrained portion 28c. The state is constrained so as not to easily switch to the state. In addition, in the present embodiment, the upstream end 24f of the first document receiving portion 24 rides on the regulated portion 20c formed at the proximal end of the document support 20 (see FIG. 4) The first state of the first document receiver 24 is maintained.

  When the first document receiving portion 24 is in the second state (FIG. 9), the restraining portion 24e formed on the first document receiving portion 24 enters the lower side of the restrained portion 28c, and the link member 28 is at the top. It will be in the state restrained so that it cannot move upwards by the restraint part 1f formed in the housing | casing 1a. As described above, the first document receiving portion 24 is restrained so as not to easily switch from the second state to the first state by the restraining means constituted by the restrained portion 28c, the restraining portion 24e, and the restraining portion 1f. It becomes a state.

  As described above, the first document receiving portion 24 is in the first state in which the first document receiving surface 24a is connected to the second document receiving surface 26a to form a smooth device appearance surface without a step (FIGS. 1 and 2). 4, FIG. 6 and FIG. 8) and a second state in which a step is formed between the downstream end of the first document receiving surface 24a and the upstream end of the second document receiving surface 26a (FIGS. 2 and 5). 7 and 9) can be switched.

  Therefore, in the second state, the document discharged by the step formed by the step (indicated by symbol h in FIG. 5) formed between the first document receiving surface 24a and the second document receiving surface 26a is in close contact with each document receiving surface. The document can be easily taken out. In the first state, the first document receiving surface 24a is connected to the second document receiving surface 26a to form a smooth (smooth) device appearance surface without a step, so that excellent device aesthetics can be obtained. It becomes possible.

  In the present embodiment, the cam groove 28b of the link member 28 that changes the posture of the first document receiving portion 24 is the first halfway when the document support 20 is rotated from the open state to the closing direction. The posture of the document receiving portion 24 is hardly changed, and the first document receiving portion 24 is changed to the first state (FIG. 1) immediately before the document support 20 is completely closed.

  In the present embodiment, when the first document receiver 24 is in the first state, the document discharge port 15 is blocked by the first document receiver 24, so that the first document receiver 24 is in the first state. The aesthetics of the device can be further improved when in the state.

  In the present embodiment, the document support 20 and the first document receiver 24 are engaged via the link member 28, and when the document support 20 is rotated in the closing direction, the first document receiver 24 is in the second state. When the document support 20 is turned in the opening direction, the first document receiving portion 24 is switched to the second state, so that the operability of the apparatus can be improved.

  By the way, the document support 20 that supports the document before feeding is supported by the pivot shafts 20a at both ends pivotally supported by the bearing portion 1d formed in the upper housing 1a as described with reference to FIG. Although supported so as to be able to rotate, the rotation shaft 20a is pivotally supported in a state in which a predetermined play is provided in the rotation axis direction (vertical direction in FIG. 10) in the bearing portion 1d.

  On the other hand, the document support 20 is formed with a tongue-shaped restricted portion 20c in the middle of the proximal end portion as shown in FIG. 11, and the restricted portion 20c is in an open posture of the document support 20. When the document is taken, that is, when the document is fed out, the movement is regulated by being sandwiched from both sides by the regulating portions 2a and 2a formed on the document leading edge support portion 2 constituting the medium conveyance path.

  That is, when the document support 20 is in the open position, the position of the rotation shaft 20a in the rotation axis direction (document width direction) is strictly determined with respect to the medium conveyance path. A good feeding result can be obtained without the direction position being out of order.

  In particular, since the document support 20 includes the edge guides 17 and 18, if the position of the document support 20 with respect to the medium conveyance path is shifted, a good conveyance result cannot be obtained. However, as described above, since the position of the document support 20 in the document width direction is strictly determined in the open position, an appropriate conveyance result (and thus an appropriate document reading result) can be obtained.

  When the document support 20 is in the closed position, that is, when configuring the appearance of the apparatus, the state where the restricted portion 20c is sandwiched by the restricting portions 2a and 2a is released. In other words, the document support 20 can move to a certain extent in the direction of the rotation axis of the rotation shaft 20a. In this state, the document support 20 is closed in the upper housing 1a as shown in FIG. It will be in the state accommodated in the accommodation recessed part 1e formed in the side.

  That is, since the position of the document support 20a is defined by the receiving recess 1e in the closed posture, the position of the document support 20 does not deviate in the receiving recess 1e, that is, the outer periphery 20d of the document support 20 is stored. Since the gap between the inner periphery of the recess 1e does not vary from left to right (upper side and lower side in FIG. 10), the aesthetic appearance of the apparatus can be ensured.

  Next, another embodiment of the present invention will be described with reference to FIGS. 12 and 13 are perspective views of an automatic document feeder 1 ′ according to another embodiment of the present invention. FIG. 12 shows the document support 20 ′ in the closed state and the document receiver 24 ′ in the first state. FIG. 13 shows a state where the document support 20 ′ is in the open state and the document receiving portion 24 ′ is in the second state.

  The document receiving portion 24 ′ constituting the document receiving means 23 ′ opens the document discharge port 15 in the first state in which the document discharge port 15 (FIG. 5) is closed, as in the case of the first document receiving unit 24 already described. The second state can be switched. Similarly to the document support 20 already described, the document support 20 ′ also has an open posture (FIG. 13) that can support the document by rotating and a closed posture (FIG. 12) that constitutes the appearance of the apparatus. Switching is possible. In FIG. 13, reference numeral 2 ′ indicates a document leading edge support portion, and reference numerals 17 ′ and 18 ′ indicate edge guides.

  In the present embodiment, when the document receiving portion 24 ′ is in the first state, the protrusions 30 are positioned below the document receiving portion 24 ′. When the document receiving portion 24 ′ is switched from the first state in FIG. 12 to the second state in FIG. 13, the protrusions 30 and 30 are formed on the document receiving surface from the slit holes 24e and 24e formed in the document receiving portion 24 ′. It is supposed to protrude. The protrusions 30a and 30a are formed with inclined surfaces on the upstream side so that the leading edge of the document is not caught when the document is discharged.

  With the above configuration, when the document receiving portion 24 ′ is in the second state, the document discharged by the protrusions 30 and 30 is lifted and can be easily taken out. Further, when the document receiving portion 24 ′ is in the first state, the protrusions 30 and 30 are located below the document receiving portion 24 ′ and are not exposed to the outside (FIG. 12). There is no loss.

  Needless to say, the embodiment described above is merely an example, and the present invention is not limited thereto. For example, in the embodiment described above, the medium conveying apparatus of the present invention is applied to the automatic document feeder provided in the scanner apparatus. However, the present invention is not limited to this, and the recording medium is used in a recording apparatus that records on the recording medium. The present invention can also be applied to a transport device that transports.
