Thereafter, the second medium is pressed, and the tray is pressed from the intermediate position toward the open position by the second medium. At this time, the state of the second medium changes to a state along the first direction while the other end of the second medium slides further on the tray.

  After the tray is rotated from the closed position to the open position, the other end portion of the second medium is placed on the tray positioned at the open position, and the other end portion of the second medium is second introduced on the tray. A configuration that can be slid into the mouth is also conceivable. However, it is easier for the user located on the other side in the first direction to visually recognize the tray located at the intermediate position than the tray located at the open position. Therefore, since the other end part of the second medium can be easily placed on the tray, the second medium can be more easily inserted into the second introduction port.

  The introduction path which is a part of the introduction side of the second transport path may be formed between the upper guide of the lower casing and the lower guide of the lower casing.

  In this case, it is preferable that the upper guide is formed so as to be positioned higher on the introduction side.

  According to this configuration, the second medium can be prevented from coming into contact with the upper guide when the second medium is introduced into the introduction path via the second introduction port. As a result, even if the second medium has an emboss, the emboss can be prevented from being damaged or the upper guide can be prevented from being damaged by the emboss.

  The sheet SH conveyed between the discharge roller 44, the discharge pinch roller 84, the card discharge roller 45, and the card discharge pinch roller 85 passes through the sheet discharge port 202 and is discharged out of the housing 2.

<Read card image>

  When reading an image of the card CA, a card tray 4 as an example of a tray is used. When reading the card image, the cover 3 is positioned at the closed position. However, as shown in FIG. 1A, the cover 3 opens the card discharge port 123 at the closed position. 123 can be discharged.

  When the card tray 4 is not used, as shown in FIG. 4B, the card tray 4 is disposed at the closed position. In order to use the card tray 4, for example, first, the tip of the card tray 4 is pushed backward by a user's finger. The card tray 4 rotates from the closed position to the open position with the rotation shaft 131 as a fulcrum. During the rotation of the card tray 4, a biasing force of the coil spring 132 acts on the card tray 4. As a result, as shown in FIG. 4B, the gravity acting on the card tray 4 and the biasing force received from the coil spring 132 are balanced at an intermediate position inclined with respect to the front-rear direction as an example of the first direction. 4 is held in its intermediate position.

  After the card tray 4 is arranged at the intermediate position, as shown in FIG. 4C, one end in the longitudinal direction of the card CA is picked by the user's finger, and the other end in the longitudinal direction of the card CA is the card tray. It is inserted from above between a pair of four guide portions 135. At this time, the card CA rubs against the rear end of the cover 3. When the other end in the longitudinal direction of the card CA contacts the inner surface 136 of the card tray 4, the card CA straddles between the inner surface 136 of the card tray 4 and the rear edge of the cover 3 and leans against the cover 3. It becomes the state. Further, the left edge of the card CA is pressed against the left guide part 135.

  Hereinafter, one end portion in the longitudinal direction of the card CA is referred to as “upstream end portion”, and the other end portion in the longitudinal direction of the card CA is referred to as “downstream end portion”.

  Thereafter, the upstream end of the card CA is pushed backward by the user's fingers. As a result, the card CA moves to the card tray while the left end edge of the card CA is guided by the left guide portion 135 and the downstream end of the card CA slides on the inner surface 136 of the card tray 4 toward the card introduction port 121. 4 leans on the tip. Thereafter, the upstream end of the card CA is further pushed backward. Thereby, the front-end | tip part of the card tray 4 is pushed below via the card | curd CA, and the card tray 4 rotates toward an open position from an intermediate position as FIG. 4D shows. As the card tray 4 rotates, the downstream end of the card CA further slides on the inner surface 136 of the card tray 4 toward the card introduction port 121, and the card CA approaches parallel to the card transport path 124. . The card tray 4 extends substantially parallel to the card transport path 124 at the open position.

  When the downstream end portion of the card CA is inserted into the card introduction port 121 and the downstream end portion comes into contact with the peripheral surfaces of the card LF rollers 43 and 83, the user's fingers are released from the card CA. . As a result, the force applied to the card CA from the user's finger is released. For example, the card tray 4 is in the closed position against the urging force of the coil spring 132 by the card CA. Maintained.

  When the card CA is inserted into the card introduction port 121, insertion of the card CA is guided by the card guide 5.

  That is, the left edge of the card CA inserted into the card introduction port 121 is separated from the left guide part 135 of the card tray 4 and inserted into the front side part 143 of the left guide part 141 of the card guide 5 as the card CA is inserted. Slide. When the upstream end of the card CA is separated from the card tray 4, the card tray 4 is moved from the closed position to the intermediate position by the biasing force of the coil spring 132.

  As the insertion of the card CA proceeds, the right front corner of the card CA comes into contact with the tip 148 of the right guide 142 of the card guide 5. When the insertion of the card CA further proceeds, the right guide portion 142 rotates so that the tip portion 148 of the right guide portion 142 is pushed by the card CA and the tip portion 148 moves to the right side. And the front-end | tip part 148 of the right side guide part 142 contact | abuts to the right edge of a card | curd, and presses the card | curd CA to the left with the urging | biasing force of the coil spring 147. FIG. As a result, the left edge of the card CA is pressed against the left guide 141, and the card CA moves while the left edge is guided by the left guide 141.

  Thus, the image reading apparatus 1 guides the right edge of a card as an example of the second medium introduced from the card tray 4 as an example of the tray into the card introduction port 121 as an example of the second introduction port. The left guide portion 141 as an example of the one side guide portion configured to be configured to be movable in the left and right direction as an example of the second direction, and the card CA introduced on the card tray 4 or the card introduction port 121 It can be said that the right side guide part 142 as an example of the other side guide part comprised so that a right end edge may be guided is provided.

  Further, the detected portion 151 is detached from the card insertion sensor 152 by the rotation of the right guide portion 142. In response to this, the level of the detection signal output from the card insertion sensor 152 changes. Therefore, it can be detected that the card CA is introduced from the card introduction port 121 based on the change in the level of the detection signal.

  The card LF roller 43 is rotated counterclockwise when viewed from the right side. As the card LF roller 43 rotates, the card LF pinch roller 83 rotates clockwise as viewed from the right side. When the leading end of the card CA inserted into the card introduction port 121 comes into contact with the peripheral surfaces of the card LF roller 43 and the card LF pinch roller 83, a conveying force is applied from the card LF roller 43 to the card CA. Is drawn between the peripheral surfaces of the card LF roller 43.

  Thereafter, the card CA passes between the first reading unit 100 and the second reading unit 60. At this time, light is emitted from the LED light sources of the CIS units 62 and 102 to the cards CA on the contact glasses 63 and 103, respectively. The reflected light from the card CA is received by the image sensors of the CIS units 62 and 102, whereby reading of images drawn on both sides of the card CA is achieved.

  The card discharge roller 45 is rotated counterclockwise when viewed from the right side. On the other hand, the card discharge pinch roller 85 rotates clockwise as viewed from the right side as the card discharge roller 45 rotates. When the downstream end of the card CA that has passed between the first reading unit 100 and the second reading unit 60 reaches the abutting portion of the peripheral surface of the card discharge roller 45, a conveying force from the card discharge roller 45 to the card CA. And the card CA is drawn between the peripheral surfaces of the card discharge roller 45 and the card discharge pinch roller 85.

  The card CA that has passed through the card outlet 123 is discharged out of the housing 2. In this way, the card CA passes through the card discharge port 123 and is discharged out of the housing 2.

<Effect>

  The card tray 4 is rotatable between a closed position that covers the card introduction port 121 and an open position that opens the card introduction port 121 around a rotation axis extending in the left-right direction below the card introduction port 121. Is provided.

  Accordingly, the card CA can be inserted into the card introduction port 121 using the card tray 4. That is, the card CA is placed on the card tray 4 where the upstream end of the card CA is picked by the user's finger and the downstream end of the card CA is located at the open position or an intermediate position between the closed position and the open position. By sliding toward the introduction port 121, the downstream end can be brought closer to the card introduction port 121. At this time, the card tray 4 guides the downstream end of the card CA to the card introduction port 121.

  Even if it is difficult for the user located on the front side of the image reading apparatus 1 to visually recognize the card introduction port 121, the user can visually recognize the card tray 4 provided so as to cover the card introduction port 121. Therefore, the upstream end of the card CA can be easily placed on the card tray 4. After the downstream end of the card CA is placed on the card tray 4, the card tray 4 guides the downstream end of the card CA to the card introduction port 121. Therefore, the card CA can be easily inserted into the card introduction port 121.

  The card tray 4 extends substantially parallel to the card transport path 124 at the open position. Therefore, it is possible to suppress the card CA from being bent when the card CA straddles the card transport path 124 and the card tray 4 located at the open position. Further, in order to suppress a conveyance abnormality such as the card CA being jammed in the middle of conveyance, it may be necessary to introduce the card into the card introduction port 121 with the card CA substantially parallel to the card conveyance path 124. If the image reading apparatus is configured not to include a card tray such as the card tray 4, the card introduction port 121 is located on the rear side of the image reading apparatus 1, so that it is difficult to make the card CA substantially parallel to the card transport path 124. However, since the image reading apparatus 1 includes the card tray 4, the card CA can easily be made substantially parallel to the card transport path 124 even though the card introduction port 121 is located on the rear side of the image reading apparatus 1. Therefore, it is possible to suppress the occurrence of conveyance abnormality such as the card CA being jammed during conveyance.

  The image reading apparatus 1 includes a coil spring 132 configured to bias the card tray 4 from the open position toward the closed position. The card tray 4 is held at an intermediate position where the gravity and the biasing force received from the coil spring 132 are balanced at an intermediate position extending in a direction inclined with respect to the front-rear direction.

  When the card CA is inserted into the card introduction port 121, the upstream end of the card CA is picked up by the user's finger, and the downstream end of the card CA is placed on the card tray 4 positioned at the intermediate position. Is done. At this time, since the card tray 4 is inclined, the downstream end of the card CA moves along the inclination. Thereafter, the card CA is pressed and the card tray 4 is pressed from the intermediate position toward the open position by the card CA. At this time, the downstream end of the card CA further slides on the card tray 4, and the state of the card CA changes to a state along the front-rear direction.

  After the card tray 4 is rotated from the closed position to the open position, the downstream end of the card CA is placed on the card tray 4 located at the open position, and the downstream end of the card CA is the card tray. 4 may be slid onto the card inlet 121. However, the card tray 4 positioned at the intermediate position is easier to visually recognize for the user positioned on the front side of the image reading apparatus 1 than the card tray 4 positioned at the open position. Therefore, since the downstream end of the card CA can be easily placed on the card tray 4, the card CA can be more easily inserted into the card introduction port 121.

  An introduction path 126 which is a rear end portion of the card transport path 124 is formed between the upper guide 127 and the lower guide 125. The upper guide 127 is formed so as to be positioned higher toward the rear side. Therefore, the card CA can be prevented from coming into contact with the upper guide 127 when the card CA is introduced into the introduction path 126 via the card introduction port 121. As a result, even if the card CA has an emboss, the emboss can be prevented from being damaged, or the upper guide 127 can be prevented from being damaged by the emboss.

  The card tray 4 is curved so as to bulge toward the introduction side.

  As a result, the card CA can be smoothly slid on the card tray 4.

  The image reading apparatus 1 includes a left guide portion 141 configured to guide the left edge of the card CA introduced from the card tray 4 to the card introduction port 121. Therefore, when the card CA is introduced from the card introduction port 121, the card CA can be prevented from shifting to the left with respect to the card introduction port 121. Therefore, the card CA can be satisfactorily introduced from the card introduction port 121.

  The image reading apparatus 1 includes a right guide portion 142 that is provided so as to be movable in the second direction and is configured to guide the right edge of the card CA introduced from the card tray 4 to the card introduction port 121. . Therefore, when the card CA is introduced from the card introduction port 121, the card CA can be prevented from shifting to the right side with respect to the card introduction port 121. Therefore, the card CA can be satisfactorily introduced from the card introduction port 121.

  Further, the right guide portion 142 is biased toward the left guide portion 141 by the coil spring 147. Therefore, when the card CA is disposed between the left guide portion 141 and the right guide portion 142, the card CA is pressed toward the left guide portion 141 by the right guide portion 142. As a result, the card CA is sandwiched between the left guide portion 141 and the right guide portion 142, and the card CA is positioned in the second direction. Therefore, the card CA can be satisfactorily introduced from the card introduction port 121.

  The right guide 142 also serves as an actuator for the card insertion sensor 152 configured to detect the introduction of the card CA into the card introduction port 121. Therefore, when the card CA is introduced from the card introduction port 121, the introduction can be detected by the card insertion sensor 152, and the card CA can be urged toward the left guide portion 141. Compared to a configuration in which the actuator of the card insertion sensor 152 and the right guide portion 142 are provided separately, the number of parts can be reduced, and the cost can be reduced.

  In the closed position, the card tray 4 forms a gap opened upward between the front end portion and the rear surface 13R of the lower housing 13. Accordingly, the card CA can be inserted from above between the front end portion of the card tray 4 located at the closed position and the rear surface 13R of the lower housing 13. Therefore, the card tray 4 can be easily moved from the closed position to the open position.

<Other configuration of card tray>

  Instead of the card tray 4 described above, a card tray 6 having the configuration shown in FIG. 6 may be employed.

  The card tray 6 includes a tray body 161 and a movable guide member 162.

  The tray main body 161 integrally includes a main body portion 163, a guide wall portion 164, an extension portion 165, a support portion 166, and a shaft portion 167.

  The guide wall portion 164 as an example of the one side guide portion rises from the left end portion of the main body portion 163.

  The extending part 165 extends rightward from the right front end part of the main body part 163.

  The support portion 166 extends from the distal end portion of the extension portion 165 to the same side as the guide wall portion 164 and is parallel to the guide wall portion 164.

  Two shaft portions 167 are provided. The two shaft portions 167 protrude rightward and leftward from the guide wall portion 164 and the support portion 166, respectively, on the same straight line extending in the left-right direction. The left and right shaft portions 167 are respectively supported by the left side surface and the right side surface of the card introduction port 121, so that the card tray 6 has a closed position and a card introduction port that cover the card introduction port 121 shown in FIG. It is provided so as to be able to rotate between an open position for opening 121.

  The movable guide member 162 as an example of the other side guide portion integrally includes a guide main body 168 and a guide support portion 169.

  The guide body 168 is disposed on the left side of the body portion 163 of the tray body 161. The guide body 168 extends in the front-rear direction. The guide body 168 is parallel to the guide wall portion 164 of the tray body 161.

  Two guide support portions 169 are provided. Each guide support portion 169 has a square bar shape. Each guide support portion 169 extends rightward from the guide main body 168 and is inserted into an insertion hole 170 formed in the main body portion 163 of the tray main body 161. The insertion hole 170 extends rightward from the left end surface of the main body 163. In the insertion hole 170, the right half 171 of the right half is formed wider than the left half 172 of the left half. As a result, the insertion hole 170 has a step surface 173 at the boundary between the right portion 171 and the left portion 172.

  Each guide support portion 169 has a stopper 174. The stopper 174 is brought into contact with the stepped surface 173 from the right side and locked while the guide body 168 is disposed at a position adjacent to the support portion 166 of the tray body 161 in the front-rear direction. Thereby, the movement amount of the movable guide member 162 is regulated.

  That is, the image reading apparatus 1 includes a stopper 174 configured to regulate the movement amount of the movable guide member 162.

  Thereby, it is possible to suppress the movable guide member 162 from being largely separated from the guide wall portion 164 or falling off from the tray main body 161. Further, in the configuration in which the movable guide member 162 is largely separated from the guide wall portion 164, the long side of the card CA is oriented in the left-right direction, that is, sideways, and the card CA is between the movable guide member 162 and the guide wall portion 164. It is allowed to be introduced. If the card CA is introduced sideways from the card introduction port 121, there is a risk that a conveyance abnormality such as the card CA being jammed during conveyance will occur. Since the movable guide member 162 is prevented from being largely separated from the guide wall portion 164, the card CA can be prevented from being introduced between the movable guide member 162 and the guide wall portion 164 in the lateral direction. As a result, it is possible to suppress the occurrence of card CA conveyance abnormality.

  Further, in the closed position, the card tray 6 forms a gap opened upward between the front end portion and the rear surface 13R of the lower housing 13.

  Accordingly, the card CA can be inserted from above between the front end portion of the card tray 6 located at the closed position and the rear surface 13R of the lower housing 13. Then, the card tray 6 can be pressed via the card CA. Therefore, the card tray 6 can be easily moved from the closed position to the open position by pressing the card tray 6 via the card CA.

<Modification>

  As mentioned above, although embodiment of this invention was described, this invention can also be implemented with another form.

  The card LF pinch roller 83 includes two pinch rollers, and the peripheral surfaces of the two pinch rollers of the card LF pinch roller 83 are minutely spaced on the left and right sides of the peripheral surface of the card LF roller 43 of the lower housing 13 respectively. Was next to each other. However, the present invention is not limited to this. For example, the card LF pinch roller 83 is composed of a single pinch roller, and the peripheral surface of the pinch roller is in contact with the peripheral surface of the card LF roller 43 of the lower housing 13 from above. Good.

  A part of the lower side of the card discharge port 123 overlapped with a part of the right side of the sheet discharge port 202. However, the present invention is not limited to this, and for example, a part on the right side of the sheet discharge port 202 may be the card discharge port 123. That is, the entire area of the card discharge port 123 may be included in the sheet discharge port 202 on the right side. Of the card transport path 124, the transport path between the flat portion 34 of the lower housing 13 and the flat portion 74 of the upper housing 14 is an area on the right side of the sheet transport path 203. However, the present invention is not limited thereto. For example, a part of the lower side of the conveyance path between the flat portion 34 of the lower housing 13 and the flat portion 74 of the upper housing 14 in the card conveyance path 124 is the sheet conveyance path 203.
