It comes into contact with a portion that overlaps with the separation portion 69, which will be described later, in the vertical direction B (vertical direction). As a result, the second support portion 62 is positioned at the support position. Further, the chute cover 2b is positioned at the support position by locking the second support portion 62 in a state of being positioned on the main frame 2a at the path configuration position. Therefore, the positioning accuracy of the second support portion 62 positioned at the support position is improved by engaging with the chute cover 2b. Further, at this time, the protrusion 2b2 comes into contact with the portion of the second support portion 62 that overlaps the separated portion 69 in the vertical direction B. In this way, the protrusion 2b2 of the shoot cover 2b positioned at the path configuration position where the required accuracy of the positioning state is relatively high abuts on the separated portion 69 of the second support portion 62 and the portion overlapping in the vertical direction B. Therefore, the position accuracy of the separation portion 69 is also improved. Therefore, a predetermined transfer resistance is applied to the paper P fed by the feeding unit 63, and it is possible to effectively suppress the double feeding of the paper P.

A separation portion 69 is provided on the second support surface 62a of the second support portion 62. The separating unit 69 abuts on the back side of the front end portion of the paper P fed by the feeding unit 63 to impart a predetermined transport resistance (a transport resistance to the extent that the paper P does not jam) to the paper P, and the paper P is subjected to. This is for separating the paper P when the paper P is double-fed. The separation portion 69 in the present embodiment is composed of a high friction member having a higher friction resistance than the friction resistance on the second support surface 62a, but any can be provided as long as it is possible to impart a predetermined transfer resistance to the paper P.

As shown in FIG. 2, the pair of prism members 66a are arranged in the pair of grooves 62b formed in the second support portion 62. The pair of grooves 62b extend in the left-right direction A in FIG. 1 along the second support surface 62a, and are arranged at positions sandwiching the separation portion 69 in the width direction D. The pair of grooves 62b has an opening formed in the second support surface 62a, and the contact surface 66a1 which is the upper surface of each prism member 66a and which can come into contact with the paper P is configured to be accessible from the opening. There is. More specifically, the pair of prism members 66a of the regulating member 66 are supported by the protruding support portion 61c protruding from the portion of the first support portion 61 facing the groove 62b toward the groove 62b, and is supported by FIG. 3 (a). ), The contact surface 66a1 of the portion downstream of the feeding direction C2 from the center of the prism member 66a in the extending direction protrudes upward from the opening of the groove 62b, and the contact of the prism member 66a. The contact surface 66a1 is configured to be movable from a retracted position where the contact surface 66a1 does not project upward from the second support surface 62a. At the restricted position, the obtuse angle θ1 formed by the contact surface 66a1 and the first support surface 61a at the portion protruding above the second support surface 62a is the second obtuse angle θ1 when the second support portion 62 is positioned at the support position. The angle becomes smaller than the obtuse angle θ2 formed by the support surface 62a and the first support surface 61a, and the movement of the paper P in the feeding direction C2 is restricted. On the other hand, at the retracted position, the contact surface 66a1 does not protrude upward from the second support surface 62a, so that the restriction on the movement of the paper P in the feeding direction C2 is lifted.

The moving mechanism 67 moves the pair of prism members 66a of the regulating member 66 by the driving force of the feeding motor 63M. That is, the moving mechanism 67 rotates each prism member 66a rotatably supported by the protruding support portion 61c of the first support portion 61. More specifically, the moving mechanism 67 is a power transmission mechanism composed of meshing of a plurality of gears or the like, and is a rotational force (driving) in the rotational direction of the feeding motor 63M when the feeding roller 64 is rotated in the forward direction. The force) is configured to move the regulating member 66 from the regulated position to the retracted position. Further, the moving mechanism 67 is configured to move the regulating member 66 from the retracted position to the regulated position by the rotational force (driving force) in the rotation direction of the feeding motor 63M when the feeding roller 64 is rotated in the reverse direction. There is. The moving mechanism 67 may have any configuration as long as the regulating member 66 can be moved by the driving force of the feed motor 63M.

The feeding unit 63 includes a feeding roller 64 arranged so as to come into contact with the uppermost paper P among the plurality of papers P supported by the first support surface 61a, and an arm 65. The feeding roller 64 is pivotally supported at the tip of the arm 65. The arm 65 is rotatably supported by the support shaft 65a and is urged by a spring or the like so that the feeding roller 64 is rotated in a direction approaching the first support surface 61a. The feed roller 64 is rotated in the forward direction by transmitting the power of the feed motor 63M (see FIG. 4) via a transmission mechanism (not shown), and the paper is supported by the first support surface 61a and the second support surface 62a. P is supplied to the transport path R via the connection path R3.

As shown in FIG. 4, the control device 100 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an ASIC (Application Specific Integrated Circuit), and the like, and these cooperate with each other. , ASF motor 13M, LF motor 21M, recording unit 30, feed motor 63M and the like are controlled. For example, when the control device 100 feeds the paper P from the feeding device 60 based on the recording command transmitted from the PC, the control device 100 rotates the feeding roller 64 in the forward direction (feeds the paper P in the feeding direction C2). The feed motor 63M is controlled so as to (rotate direction). At this time, the moving mechanism 67 moves the regulating member 66 from the regulated position to the retracted position so that the paper P can be fed in the feeding direction C2, and the paper P in contact with the feeding roller 64 is fed in the feeding direction C2. Will be done. At this time, the control device 100 also controls the LF motor 21M and the recording unit 30, and performs a recording operation of recording an image or the like on the paper P while conveying the paper P along the linear path R2. The control device 100 feeds all the paper P to be fed this time by the feeding roller 64, and after the rear end of the paper P finally fed has passed through the feeding roller 64, the feeding roller 64 is rotated in the reverse direction. The feed motor 63M is controlled so as to be operated. As a result, the regulating member 66 is moved from the retracted position to the regulated position by the moving mechanism 67, and the movement of the paper P in the feeding direction C2 is restricted.

Subsequently, the operation when cleaning the second support surface 62a of the second support portion 62 will be described below with reference to FIG. As shown in FIG. 3A, the chute cover 2b is usually arranged at the path configuration position, and the second support portion 62 is positioned at the support position by engaging with the chute cover 2b. This enables printing and the like with the printer 1. When performing maintenance to clean the second support surface 62a, the user rotates the chute cover 2b from the path configuration position to the open position as shown in FIG. 3B. As a result, the lock of the second support portion 62 by the chute cover 2b is released, and the second support portion 62 rotates so as to hang downward. That is, the second support portion 62 rotates from the support position to the cleaning position around the rotation shaft 61b. Since the second support portion 62 is arranged at the cleaning position simply by rotating the chute cover 2b in this way, the user can use the outside of the device housing 2 between the second support portion 62 and the transport guide 23a. It is possible to put a hand and wipe off the foreign matter (glue or the like) adhering to the second support surface 62a with a cloth or the like. In this way, the second support surface 62a can be cleaned.

Further, the restricting member 66 is usually positioned at the restricting position even if the chute cover 2b is rotated from the path configuration position to the open position. Therefore, as shown in FIG. 3B, even if the second support portion 62 rotates to the cleaning position due to the rotation of the chute cover 2b, a plurality of sheets supported by the second support surface 62a. P is supported by the contact surface 66a1 of the regulating member 66 (prism member 66a). That is, the plurality of sheets P are supported by the first support surface 61a and the contact surface 66a1. As a result, even if the chute cover 2b is rotated to rotate the second support portion 62 to the cleaning position while the plurality of papers P are supported by the second support surface 62a, the plurality of papers P will fall off. Can be suppressed.

When the chute cover 2b is rotated back from the open position to the path configuration position, a part thereof (a portion extending from the downstream end of the transport guide 23b in the transport direction to the protrusion) sequentially contacts the second support portion 62. The second support portion 62 can be rotated around the rotation shaft 61b. That is, the second support portion 62 can be returned from the cleaning position to the support position only by returning the chute cover 62 from the open position to the path configuration position.

As described above, according to the printer 1 and the feeding device 60 of the present embodiment, the chute cover 2b is rotated from the state of being locked to the second support portion 62 to release the lock. Then, the second support portion 62 can be rotated from the support position to the cleaning position. Therefore, for example, even if a plurality of label papers are set as the paper P in the feeding device 60 and the glue of the label paper adheres to the second support surface 62a of the second support portion 62, the second support surface 62a It becomes easier to clean at the cleaning position. Therefore, it is possible to prevent the paper P from being jammed by the glue adhering to the second support surface 62a.

Since the second support portion 62 is positioned at the support position by being locked to the chute cover 2b which is a part of the device housing 2, the chute cover 2b is rotated from the path configuration position to the open position. Then, the second support portion 62 can be rotated and moved to the cleaning position.

As a modification, as shown in FIG. 5, a holding mechanism 80 capable of holding the second support portion 62 may be provided separately from the shoot cover 2b. The holding mechanism 80 includes a pair of holding members 81 and a pair of springs 82. Each holding member 81 has a rod shape extending along the width direction D, and is supported by the horizontal plane 2a1 of the main frame 2a so as to be movable in the width direction D. The pair of holding members 81 and the spring 82 are arranged separately on the left and right along the width direction D. Further, the holding member 81 is at the position shown in FIG. 5A, and its inner end portion overlaps with the second support portion 62 along the vertical direction B in the width direction D, and the second support portion 62 is lowered. The holding position that can be held from the above and the position shown in FIG. 5 (c), the inner end portion of the holding member 81 does not overlap with the second support portion 62 along the vertical direction B, and the whole thereof is the horizontal plane 2a1. It is configured to be movable so as to be separated from the overlapping second support portion 62 and the release position for releasing the holding of the second support portion 62.

The spring 82 extends along the width direction D, its outer end is fixed to the fixing portion 2a2 formed so as to project downward on the horizontal plane 2a1, and the inner end is fixed to the holding member 81. ing. As a result, the holding member 81 is urged by the spring 82 from the release position toward the holding position.

In this modification, when the second support portion 62 is rotated from the support position to the cleaning position, the chute cover 2b is first rotated from the path configuration position to the open position. As a result, as shown in FIG. 5B, both ends of the second support portion 62 in the width direction D are held by only the pair of holding members 81 from below. After that, only when the second support surface 62a of the second support portion 62 is cleaned, the user moves the holding member 81 outward against the urging force of the spring 82, as shown in FIG. 5 (c). As a result, the second support portion 62 can rotate so as to hang downward. That is, the second support portion 62 rotates from the support position to the cleaning position.

Also in this modification, since the second support portion 62 can be rotated from the support position to the cleaning position as in the above-described embodiment, the second support surface 62a can be cleaned at the cleaning position. Therefore, it is possible to prevent the paper P from being jammed by the glue adhering to the second support surface 62a. Further, by having the holding member 81, even if the second support portion 62 is released from the lock by the chute cover 2b, the second support portion 62 is moved from the holding position to the release position until the holding member 81 is released. Does not rotate. In this case, for example, even if the regulating member 66 is not provided, the second support portion 62 does not rotate to the cleaning position simply by rotating the chute cover 2b to the open position, so that the feeding device 60 has a plurality of portions. Even if the paper P is set, it will not fall off.

In the above-mentioned modification, the holding mechanism 80 has the spring 82, but if the holding member 81 is configured to be movable between the holding position and the releasing position, it is composed of only the holding member 81. It may have been done. In this case, the user can selectively hold and release the second support portion 62 by appropriately moving the holding member 81 between the holding position and the releasing position.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made as long as it is described in the claims. For example, the second support portion 62 is locked to a movable part of the device housing 2 when it is in the support position, and when the part is moved to release the lock, the second support portion 62 is engaged. May be configured to be able to move without rotating in the horizontal direction or in the in-plane direction of the second support surface 62a when the second support portion 62 is in the support position. Further, the second support portion 62 is configured to be rotatable around the left end portion in FIG. 1, but other portions (for example, the center or the end portion on the opposite side (conveyance guide 23c side)) are included. It may be configured to be rotatable as a center.

In the above-described embodiment and modification, the second support portion 62 at the support position and the chute cover 2b are configured to be lockable, but if it is a movable portion of the device housing 2, it is other than the chute cover 2b. It may be configured so that it can be locked with the portion of. Further, the separation portion 69 may not be provided. The regulating member 66 and the moving mechanism 67 may not be provided.

Further, the recording unit 30 may be an inkjet type, a thermal type, a laser type or the like. The present invention is not limited to printers, and can be applied to facsimiles, copiers, multifunction devices, and the like. The recording medium is not limited to paper, and may be label paper or the like.
