Description

  The present invention relates to an image reading apparatus and a conveying apparatus.

  An introduction port for introducing a sheet is formed on the back side of the housing of the image reading apparatus disclosed in Patent Document 1. On the other hand, a discharge port for discharging the sheet is formed on the front side of the housing. A conveyance path from the introduction port to the discharge port is formed inside the housing. The image reading apparatus includes an image reading unit and a pair of conveyance rollers.

  The sheet introduced from the introduction port is conveyed by the conveyance roller pair toward the discharge port on the conveyance path. In the middle of this conveyance, the image on the sheet is read by the image reading unit.

  The image reading device disclosed in Patent Document 1 is configured to be able to read an image drawn on a card that is narrower than a sheet. Specifically, a part of the discharge port also serves as a card introduction port for introducing a card and a card discharge port for discharging a card. In addition, a mechanism is provided for rotationally driving the conveying roller pair in one direction and the other direction.

  When a card is inserted into the card introduction port, the conveyance roller pair is rotated in the direction opposite to that during conveyance of the sheet, and the card is drawn into the card introduction port by the conveyance roller pair.

A conveyance force is applied to the.

  The sheet SH that has passed between the LF roller 42, the LF pinch roller 82, the card LF roller 43, and the card LF pinch roller 83 passes over the contact glasses 63 and 103. At this time, light is emitted from the LED light sources of the CIS units 62 and 102 to the sheets SH on the contact glasses 63 and 103, respectively. Then, the reflected light on the sheet SH is received by the image sensors of the CIS units 62 and 102, whereby reading of images drawn on both surfaces of the sheet SH is achieved.

  The discharge roller 44 and the card discharge roller 45 are rotated counterclockwise when viewed from the right side. The discharge pinch roller 84 and the card discharge pinch roller 85 rotate clockwise as viewed from the right side. When the leading end of the sheet SH that has passed over the contact glasses 63 and 103 reaches the discharge roller 44 and the card discharge roller 45, a conveying force is applied to the sheet SH from the discharge roller 44 and the card discharge roller 45.

  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.

<Use of tray>

  When the front end of the mounting portion 131 is pushed downward in a state where the tray 4 is located at the closed position, the tray 4 rotates about the rotation shaft 148 as a fulcrum. By this rotation, the tray 4 moves from the closed position to the open position as shown in FIG. 2B. When the tray 4 is located at the open position, the wall 141 crosses the sheet discharge port 202 in the vertical direction.

  After the tray 4 is placed in the open position, one end of the card CA in the longitudinal direction is picked by the user's finger, and the other end in the longitudinal direction of the card CA is the first wall 141L and the second wall of the tray 4. 141R is inserted from above. Thereafter, the card CA is moved toward the card introduction port 121 on the placement surface 131U of the tray 4 while the left edge and the right edge are guided by the first wall 141L and the second wall 141R.

  When the other end of the card CA is inserted into the card introduction port 121 and the other end abuts between the peripheral surface of the card discharge roller 45 and the peripheral surface of the card discharge pinch roller 85, the user's finger is Released from card CA.

<Read card image>

  The card transport path 124 as an example of the second transport path includes a space between the flat portion 34 of the upper surface 13U of the lower housing 13 and the flat portion 74 of the lower surface 14B of the upper housing 14 and the upper surface 13U of the lower housing 13. Is formed in a space below the inclined portion 33.

  As shown in FIGS. 3 and 4, a card passage port 122 as an example of an opening is formed between the front lower end portion of the inclined portion 33 of the lower housing 13 and the flat portion 34. The card passage port 122 connects the common path CP and the independent path IP. Therefore, the card CA can go back and forth between the common path CP and the independent path IP through the card passage port 122.

  When reading the image of the card CA, the card CA is inserted into the card introduction port 121 with the short side of the card CA as the head, that is, along the short side of the card CA in the left-right direction.

  When the tray 4 is displaced to the open position, the card CA introduced into the card introduction port 121 is conveyed, and the card reading mode in which the image of the card CA can be read is set. When the tray 4 is displaced to the open position and the card CA is inserted into the card introduction port 121, the card discharge roller 45 is rotated clockwise as viewed from the right side. The card discharge pinch roller 85 rotates counterclockwise as viewed from the right side as the card discharge roller 45 rotates. A conveying force is applied to the card CA from the card discharge roller 45 and the card discharge pinch roller 85, and the card CA is drawn between the peripheral surface of the card discharge roller 45 and the peripheral surface of the card discharge pinch roller 85.

  Thereafter, the card CA passes between the first reading unit 100 and the second reading unit 60.

  The card LF roller 43 is rotated clockwise as viewed from the right side simultaneously with the start of rotation of the card discharge roller 45. As the card LF roller 43 rotates, the card LF pinch roller 83 rotates counterclockwise as viewed from the right side. When the leading end of the card CA passing between the first reading unit 100 and the second reading unit 60 reaches between the peripheral surface of the card LF roller 43 and the peripheral surface of the card LF pinch roller 83, the card LF roller 43 Then, a conveying force is applied to the card CA, and the card CA is drawn between the peripheral surface of the card LF roller 43 and the peripheral surface of the card LF pinch roller 83.

  The card CA passes through the card passage opening 122 and reaches a position where the rear end opposite to the front end of the card CA is sandwiched between the peripheral surface of the card LF roller 43 and the peripheral surface of the card LF pinch roller 83. When the conveyance of the card CA proceeds, the rotation of the card LF roller 43 and the card discharge roller 45 is stopped. When the rotation of the card LF roller 43 and the card discharge roller 45 is stopped, the card CA is temporarily stopped with the leading end thereof being cued from the cueing opening 128.

  Thereafter, the card LF roller 43 and the card discharge roller 45 are rotated counterclockwise as viewed from the right side. The card LF pinch roller 83 and the card discharge pinch roller 85 rotate clockwise as viewed from the right side. As a result, the card CA is reversed in its transport direction and is transported in the direction from the rear side toward the front side.

  The card CA passes between the first reading unit 100 and the second reading unit 60. At this time, the card CA is irradiated with light from the LED light sources of the CIS units 62 and 102, respectively. Then, when the reflected light from the card CA is received by the image sensors of the CIS units 62 and 102, the images drawn on both surfaces of the card CA are read.

  When the leading end of the card CA that has passed between the first reading unit 100 and the second reading unit 60 reaches a contact portion between the peripheral surface of the card discharge roller 45 and the peripheral surface of the card discharge pinch roller 85, the card is discharged. A conveyance force is applied to the card CA from the roller 45, and the card CA is drawn between the peripheral surface of the card discharge roller 45 and the peripheral surface of the card discharge pinch roller 85. Then, the card CA transported between the card discharge roller 45 and the card discharge pinch roller 85 passes through the card introduction port 121, and between the first wall 141L and the second wall 141R of the tray 4 or a housing. 2 is discharged outside.

  In this way, the card CA introduced from the card introduction port 121 is switched back in the housing 2 and discharged from the card introduction port 121.

<Sensor>

  As shown in FIG. 4, the image reading apparatus 1 includes an open position sensor 162. The open position sensor 162 is composed of, for example, a micro switch, and is provided on the left side of the slit 161. The actuator 163 of the open position sensor 162 extends rightward and protrudes into the slit 161. When the actuator 163 is displaced from the normal position, that is, when the right end of the actuator 163 moves from the position extending rightward to the rear side, the level of the signal output from the open position sensor 162 changes from low level to high level. .

  Therefore, based on the level of the signal output from the open position sensor 162, the presence or absence of the second support plate portion 144 at the position of the actuator 163 in the slit 161, that is, whether or not the tray 4 is in the open position is detected. be able to.

  That is, a slit 161 into which the second wall 141 </ b> R which is a part of the wall portion 141 can enter as the tray 4 rotates is provided on the discharge side surface of the housing 2. The second wall 141R protrudes larger with respect to the placement surface 131U than the first wall 141L. The open position sensor 162 detects whether or not the wall portion 141 has entered the slit 161.

<Electrical configuration>

  As shown in FIG. 7, the image reading apparatus 1 includes a control unit 172 having a configuration including a microcomputer.

  A signal output from the open position sensor 162 is input to the control unit 172. The control unit 172 transmits a driving force of the motor 171 to the supply roller 41, the LF roller 42, the card LF roller 43, the discharge roller 44, and the card discharge roller 45 based on the output signal of the open position sensor 162. To control the operation.

<Control details>

  While the image reading apparatus 1 is powered on, the control unit 172 repeats the process shown in FIG.

  In the process shown in FIG. 8, it is first determined whether or not the tray 4 is in the open position (step S1). Whether or not the tray 4 is in the open position is determined based on the level of the signal output from the open position sensor 162. That is, if the level of the signal output from the open position sensor 162 is low, it is determined that the tray 4 is located at the open position. On the other hand, if the level of the signal output from the open position sensor 162 is high, it is determined that the tray 4 is not located at the open position.

  When the tray 4 is in the open position (YES in step S1), the drive transmission mechanism 173 is controlled so that the motor 171 rotates the card LF roller 43, the card discharge roller 45, and the like clockwise as viewed from the right side. Thus, the driving force can be transmitted. Thereby, the taking-in of the card CA from the card introduction port 121 is permitted (step S2).

  On the other hand, when the tray 4 is not in the open position (NO in step S1), the drive transmission mechanism 173 is controlled to drive the motor 171 so that the supply roller 41 and the like rotate counterclockwise as viewed from the right side. It is assumed that power can be transmitted. As a result, the card discharge roller 45 and the like also rotate counterclockwise when viewed from the right side, so that the card CA cannot be taken in from the card introduction port 121 on the front side of the image reading apparatus 1. That is, even if the card CA is about to be inserted into the card introduction port 121, the card CA is discharged to the front of the image reading apparatus 1 by the card discharge roller 45 that rotates counterclockwise and is not taken into the card introduction port 121. At the same time, the sheet SH is permitted to be taken in from the sheet introduction port 201 on the rear side of the image reading apparatus 1.

<Effect>

  As described above, the housing 2 is formed with the sheet introduction port 201, the sheet discharge port 202, the sheet conveyance path 203, and the card introduction port 121. The sheet inlet 201 is formed on the rear side of the housing 2. The sheet discharge port 202 is formed on the front side of the housing 2. The sheet conveyance path 203 is configured to convey the sheet SH from the sheet introduction port 201 to the sheet discharge port 202. The card introduction port 121 is provided as a part of the sheet discharge port 202, and is configured such that a card CA narrower than the sheet SH is introduced.

  The first reading unit 100 and the second reading unit 60 read the image of the sheet SH conveyed through the sheet conveyance path 203 and the card CA introduced into the card introduction port 121.

  The tray 4 is disposed at the same position as the card introduction port 121 in the left-right direction. The tray 4 is provided so as to be rotatable between a closed position closed with respect to the housing 2 and an open position opened with respect to the housing 2 around a rotation shaft 148 extending in the left-right direction. In addition, when the tray 4 is located at the open position, the tray 4 has a mounting portion 131 that extends in the front-rear direction and the left-right direction, and a wall portion 141 that protrudes upward from the mounting surface 131U that is the upper surface and extends in the front-rear direction. With.

  The card CA is inserted into the card introduction port 121 using the tray 4 located at the open position. That is, the card CA is placed on the placement surface 131U of the tray 4 positioned at the open position, and the card CA is moved in the front-rear direction along the wall portion 141 on the placement surface 131U. The CA is inserted into the card introduction port 121. Since the card CA is moved along the wall 141, it is possible to suppress the card CA from being displaced from the card introduction port 121 or the posture of the card CA being inclined with respect to the front-rear direction. As a result, the card CA can be inserted into the card introduction port 121 satisfactorily.

  The wall portion 141 is provided with a space in the left-right direction, protrudes upward from the placement surface 131U, and extends in the front-rear direction, the first wall 141L, the second wall 141R, the first support plate portion 143, and the second support plate. Part 144 is provided.

  By disposing the card CA between the first wall 141L and the first support plate portion 143 and the second wall 141R and the second support plate portion 144, the card CA can be positioned in the left-right direction. As a result, the card CA can be inserted into the card introduction port 121 even better.

  The distance between the first wall 141L and the first support plate 143 and the second wall 141R and the second support plate 144 is larger than the short side width of the card CA and smaller than the long side width of the card CA.

  As a result, the card CA is inserted into the card introduction port 121 with its short side along the left-right direction. As a result, it is possible to prevent the card CA from being inserted into the card introduction port 121 in a direction in which the long side is along the left-right direction.

  When the tray 4 is located at the closed position, the sheet discharge port 202 is opened in the left-right direction.

  The wall 141 crosses the sheet discharge port 202 in the vertical direction when the tray 4 is located at the open position.

  Thereby, discharge of the sheet SH from the sheet discharge port 202 can be suppressed in a state where the tray 4 is located at the open position. Therefore, when the tray 4 is in the closed position, the image of the card CA is read, and when the tray 4 is in the open position, the image of the sheet SH is read. Can be easily recognized.

  The rotation shaft 148 is disposed above the card introduction port 121.

  Thereby, when the sheet SH is discharged from the sheet discharge port 202, the sheet SH can be prevented from colliding with the tray 4. That is, when the sheet SH is discharged from the sheet discharge port 202, the portion of the sheet SH that has escaped from the sheet discharge port 202 hangs down due to its gravity. In the configuration in which the rotation shaft 148 is disposed above the card introduction port 121, the tray 4 positioned at the closed position is disposed above the card introduction port 121. Therefore, it is possible to suppress the portion of the sheet SH that has escaped from the sheet discharge port 202 from colliding with the tray 4 located at the closed position.

When the sensor 162 detects that the tray 4 is in the open position, the card LF roller 43 is driven clockwise as viewed from the right side, and the tray 4 is positioned in the open position by the open position sensor 162. When the absence is detected, the supply roller 41 and the LF roller 42 are configured to be driven counterclockwise when viewed from the right side. And a control unit 172.

  According to this configuration, when the tray 4 is located at the open position, the card CA is transported through the card transport path 204. On the other hand, when the tray 4 is in the closed position, the sheet SH is transported through the sheet transport path 203. Accordingly, switching between the reading mode of the card CA and the reading mode of the sheet SH is performed based on the opening / closing of the tray 4. Accordingly, the user can easily recognize how to use the image reading apparatus 1. That is, the user can easily recognize that the image of the card CA is read when the tray 4 is open and the image of the sheet SH is read when the tray 4 is closed.

  A slit 161 into which a part of the wall 141 can enter as the tray 4 rotates is provided on the discharge side surface of the housing 2, and the open position sensor 162 has the wall 141 entering the slit. It is comprised so that it may detect whether it is doing.

  Further, two concave portions 302 are formed on the front surface 13F of the lower housing 13. One recess 302 is formed on the left side of the left card discharge roller 45. One concave portion 302 extends over the upper end edge of the front surface 13F and the lower end portion of the left card discharge roller 45 in the vertical direction. The other concave portion 302 straddles the upper end edge of the front surface 13F and the lower end portion of the left card discharge roller 45 in the vertical direction.

  The other end portions of the first support portion 351L and the second support portion 351R are disposed at the lower end portion in the recess 301. A rotation shaft 348 is provided at the lower end of each recess 301. The rotation shaft 348 extends in the left-right direction. The rotation shaft 348 is inserted into the bearing holes 352 at the other end portions of the first support portion 351L and the second support portion 351R. Accordingly, the first support portion 351L and the second support portion 351R are rotatably supported by the respective rotation shafts 348.

  As shown in FIG. 12B, the image reading apparatus 1 includes an open position sensor 362. The open position sensor 362 is composed of, for example, a micro switch. The actuator 363 of the open position sensor 362 protrudes upward from the bottom surface 300S. When the tray 4 is in the open position, a low level signal is output from the open position sensor 362. When the tray 4 is located at the open position, the placement surface 331U of the tray 4 abuts against the actuator 363, and the actuator 363 is displaced downward, whereby a high level signal is output from the open position sensor 362.

  Therefore, whether or not the tray 4 is in the open position can be detected based on the level of the signal output from the open position sensor 362.

  Further, the image reading apparatus 1 includes a card reading start switch 371 for instructing start of reading an image of the card CA. The card reading start switch 371 includes, for example, a rectangular button, and is disposed in an opening 372 formed in the bottom surface 300S of the recess 300. The card reading start switch 371 is arranged so that the upper surface thereof is on the same plane as the bottom surface 300S. When the card reading start switch 371 is pressed, the driving of the card LF roller 43 is started. When the tray 4 is located at the closed position, the card reading start switch 371 is covered with the tray 4, so that the card reading start switch 371 cannot be pressed. Therefore, the card reading start switch 371 can be pushed only when the tray 4 is in the open position, and the card CA can be drawn into the card introduction port 121 to read the image of the card CA.

  In addition, various design changes can be made to the above-described configuration within the scope of the matters described in the claims.

  For example, in the above-described embodiment, the driving force of the motor 171 is transmitted to the supply roller 41, the LF roller 42, the card LF roller 43, the discharge roller 44, and the card discharge roller 45 through the drive transmission mechanism 173. However, the present invention is not limited to this. For example, the driving force of the motor 171 may be transmitted separately by the supply roller 41, the LF roller 42, and the card LF roller 43. Also, two motors may be provided, and each motor may be connected to the supply roller 41, the LF roller 42, and the card LF roller 43 via separate drive transmission mechanisms. In these cases, when the tray 4 is located at the open position, the driving force is transmitted to the card LF roller 43, and the driving force transmission to the supply roller 41 and the LF roller 42 is cut off. Further, when the tray 4 is located at the closed position, the transmission of the driving force to the card LF roller 43 is cut off, and the driving force is transmitted to the supply roller 41 and the LF roller 42. Even with such a configuration, it is possible to switch between the reading mode of the card CA and the reading mode of the sheet SH based on opening and closing of the tray 4.
