In the printing unit 19b, the upper frame unit 24 can be opened and closed with the attachment portion of the main shaft 27 as a fulcrum for exchanging the ink ribbon. . When the upper frame unit 24 is opened, the rear end surface of the upper frame unit 24 enters the space 19e. Thereby, the optical axis from the sensor 34 which is a light emitting element is displaced, and the sensor 16 which is a light receiving element is turned from OFF to ON. Therefore, when the page turning operation is not performed and the sensor 16 is turned off, it can be determined that the upper frame unit 24 has been opened, and a sensor for detecting that the page of the bankbook has been flipped up, and the printing unit The sensor for detecting that the upper frame unit 24 of 19b is opened can be shared.

  FIG. 9 is a control block diagram of the passbook slip printer. Reference numeral 35 denotes a main control unit, to which an inserter unit 19a, a printing unit 19b, an ATP unit 19c, and a power supply unit 19d are connected. In FIG. 9, the configurations of the inserter unit 19a, the printing unit 19b, and the power supply unit 19d are not shown.

  A DC motor 36 drives the turn page roller assembly 5. A pulse motor 37 drives the feed roller 4 and the pressing feed roller 6. A pulse motor 38 moves the pressing feed roller 6 up and down. 12 is a slit sensor and 16 is a sensor.

  10 to 13 are explanatory diagrams showing the operation of the present embodiment, and the page turning operation will be described below. Here, the insertion direction of the bankbook will be described. When the closed passbook is set on the passbook stage 17b, it is set so that the binding portion comes to the front end in the insertion direction. When setting an open passbook, set the cover so that the cover side is at the tip in the insertion direction. The following description of the operation will be made taking the case of an open bankbook as an example.

  When the main control unit 35 prints on the passbook by the printing unit 19b, or when printing is performed, the main control unit 35 determines that the page turning is necessary based on the reading result received from the output of the reading sensor 32 or the like. As shown in FIG. 10A, the pulse motor 37 (not shown) of the printing unit 19b is driven and the feed motor 30, the feed roller 4 and the pressing feed roller 6 are rotated by driving the pulse motor 37. Then, the bankbook 40 is conveyed so that the page to be turned from the printing unit 19b is at a predetermined position below the turn page roller assembly 5. As described above, the insertion direction of the passbook 40 is such that the cover side is at the leading end of the insertion direction, and when it is determined that page turning is necessary, the page is a page behind the binding portion 40a. . Therefore, the passbook 40 is stopped at a position where a predetermined amount is conveyed after the binding portion 40a passes through the turn page roller assembly 5.

  At this time, the turn page roller assembly 5 is in the home position where the protruding portion 10a is on the upper side and is not rotated. Further, the pressing feed roller 6 is raised by a predetermined amount by driving the pulse motor 38 so that the conveyance force is generated in a state where the passbook 40 is pressed against the idle roller 7. When the bankbook 40 is transported to the predetermined position, the main control unit 35 stops driving the pulse motor (not shown) of the printing unit 19b and stops driving the pulse motor 37, so that the transport feed roller 30 and the transport feed are stopped. The passbook 40 is stopped by stopping the rotation of the roller 4 and the pressing feed roller 6.

  Here, the distance between the turn page roller assembly 5 and the pressing feed roller 6 and the conveyance feed roller 4 is set so that both the turn page roller assembly 5 and the pressing feed roller 6 and the conveyance feed roller 4 are connected to the passbook 40 in a bound state. The positional relationship can be clamped, and it is possible to handle the case where the cover of the closed bankbook 40 is turned.

  Further, as described above, when turning the page behind the binding portion 40a, if the bankbook 40 is conveyed to the predetermined position, the binding portion 40a enters the slope 2b described with reference to FIG. Next, the pressing force by the pressing feed roller 6 is changed according to the thickness of the portion of the bankbook 40 where the page is turned.

  That is, when printing on the bankbook 40, the main control unit 35 uses the processing of the printing unit 19b to obtain an optimum platen gap by using the amount of movement of the platen 29 to determine the thickness of the portion to be printed on the bankbook 40. Looking for. Since the page to be turned is on the portion to be printed, the thickness of the portion to be turned can be recognized. Therefore, the position of the pressing feed roller 6 is changed depending on the thickness of the part to be turned. When the page turning portion is thick, that is, when the number of pages under the page to be turned is large, the main control unit 35 weakens the pressing force by the pressing feed roller 6 and turns the page. Is thin, that is, when the number of pages under the page to be turned is small, the pulse motor 38 is driven to increase the pressing force of the pressing feed roller 6 and the pressing feed roller 6 Change position. In this way, by changing the pressing force of the pressing feed roller 6 depending on the thickness of the portion of the book 40 that turns the page, when the uppermost page is lifted by the protruding portion 10a described below, the second and subsequent pages are changed. Can be prevented from being lifted.

  Next, the main control unit 35 drives the DC motor 36 to rotate the turn page roller assembly 5 in the arrow A direction. When the turn page roller assembly 5 at the home position is rotated in the direction of arrow A, as shown in FIG. 10B, the protruding portion 10a starts to contact the page to be turned from the opposite side of the binding portion 40a. To do. Since the passbook 40 as a whole is clamped by the conveying feed roller 4 and does not move, when the turn page roller assembly 5 is rotated in the direction of arrow A, as shown in FIG. Into the curved portion of the rear open guide 14. Here, since the protruding portion 10 a protrudes from the circumferential surface of the idle roller 7, the protruding portion 10 a can contact a page for turning the page of the bankbook 40. Moreover, by making the turn page roller 8 into a fan shape, the portions other than the protruding portion 10a of the turn page roller 8 are less likely to come into contact with the page of the passbook 40 where the page is turned, and the protruding portion 10a can reliably turn the page. It can be done.

  When the main control unit 35 detects the slit portion 11 c from the output of the slit sensor 12, the main control unit 35 stops the driving of the DC motor 36 and stops the rotation of the turn page roller assembly 5. When the slit portion 11c comes to the slit sensor 12 when the turn page roller assembly 5 is rotated in the direction of arrow A, as shown in FIG. It will not fall off because it is touching. Further, in the process where the page is bowed, the rear open guide 14 is contacted. The rear open guide 14 is supported by the protrusion 14a so as to be freely opened and closed, and the bowed portion of the bankbook 40 is rear opened. Since the curved portion of the guide 14 enters and is in contact, the rear open guide 14 is easily pushed up by the bow-shaped page 40b, and the page 40b lifted by its own weight is pressed to form the bow-shaped mountain. In order to make it easy to perform a lifting operation, which will be described later, on the open side opposite to the binding portion 40a. Further, when the rear open guide 14 is lifted by the page 40b having the bow shape of the bankbook 40, the balance between the frictional force between the protruding portion 10a and the page 40b lifted by the bow shape and the weight of the rear open guide 14 is balanced. Even when it becomes difficult to lift the rear open guide 14, the cam 15b described with reference to FIG. Since a force for pushing up the rear open guide 14 is added by starting contact with the push-up portion 14b, the push-up force by the cam 15b is added in addition to the push-up force by the bow-shaped page 40b, so that the rear open guide 14 is It is easily pushed up by the page 40b having the bow shape.

  Next, the main control unit 35 drives the pulse motor 38 and lowers the pressing feed roller 6 to release the pressing force to the turn page roller assembly 5 as shown in FIG. At this time, the uppermost page 40b that is in contact with the protruding portion 10a does not fall, but the page below that page is released from the pressing force by the pressing feed roller 6, so that the uppermost page 40b is changed to the uppermost page 40b. Even if it is hung and lifted, it returns to its original position and prevents multiple pages from being turned.

  Next, the main control unit 35 drives the pulse motor 37 to rotate the transport feed roller 4 in the returning direction. At this time, the pressing feed roller 6 also rotates, but since it is not in contact with the bankbook 40, no conveying force is generated in the pressing feed roller 6 portion. When the conveyance feed roller 4 is rotated in the return direction, the passbook 40 moves in the return direction as shown in FIG. When the bankbook 40 moves in the returning direction, the uppermost page 40b remains in contact with the protruding portion 10a, so that the bow-shaped mountain increases.

  When the main controller 35 returns the bankbook 40 by a predetermined amount, the main controller 35 drives the pulse motor 37 to stop the conveyance feed roller 4. Note that the return amount of the bankbook 40 is changed in an increasing direction at the time of a retry, which will be described later, to facilitate turning. Next, the main control unit 35 drives the DC motor 36 to further rotate the turn page roller assembly 5 in the arrow A direction. Then, as shown in FIG. 13A, the uppermost page 40b that is in contact with the protruding portion 10a is lifted up and then extended from the bow shape by the waist of the page itself. Falls onto the turnpage roller assembly 5. At this time, since the turn page roller assembly 5 side of the rear open guide 14 has a shape curved upward, even if the page 40b that is flipped up is pressed by its own weight, the page is not greatly curved. . The fact that the page is flipped up can be recognized from the output of the sensor 16.

  As described above, when the uppermost page 40b of the bankbook 40 is lifted in a bow shape by the protruding portion 10a, the page 40b is pressed by the rear open guide 14, so that the bow-shaped mountain comes to the open side. It has become. Further, since the binding portion 40a is on the slope 2b shown in FIG. 1, the bankbook 40 is warped, and the page on the horizontal plane 2a side to be turned is splashed by the waist of the page itself. There is a power to go up. Therefore, it is easy to perform the raising by the protruding portion 10a.

  When the main control unit 35 detects the first edge 11 a from the output of the slit sensor 12, the main control unit 35 stops the rotation of the DC motor 36. As a result, the turn page roller assembly 5 stops at the home position. In addition, since the motor which drives the turn page roller assembly 5 uses the DC motor 36, the turn sensor roller assembly 5 is rotated in the direction of arrow A, and the slit sensor 12 detects the first edge portion 11a. When the rotation of the motor 36 is stopped, it takes time until the motor 36 is completely stopped. Therefore, the positional relationship between the first edge portion 11a and the protruding portion 10a is such that the first edge portion 11a passes through the slit sensor 12. From this, the positional relationship is such that the protruding portion 10a faces almost directly after rotating by a predetermined angle.

  Further, the slit disk 11 has a shape in which two edge portions 11a and 11b and one slit 11c are provided, so that the output of the slit sensor 12 is turned from ON to OFF in one direction of rotation. The main controller 35 can manage the position of the turn page roller assembly 5 without counting the number of slits or comparing the slit intervals.

  When the turn page roller assembly 5 is in the home position, as described in FIG. 5, the rear open guide 14 is lifted by the cam 15b, and the rear open guide 14 and the idle roller 7 of the turn page roller assembly 5 are protruded. There is a gap between the part 10a and the rubber part 10b, and the flipped-up page 40b is contained in this gap.

  Next, the main control unit 35 drives the pulse motor 38 to raise the pressing feed roller 6, presses the bankbook 40 against the idle roller 7 by the pressing feed roller 6, and controls the pulse motor 37 and the printing unit 19 b (not shown). The pulse motor is driven to rotate the transport feed roller 30, the transport feed roller 4 and the pressing feed roller 6 in the return direction. Then, as shown in FIG. 13B, the uppermost page 40b that is flipped up is pulled out from the gap between the rear open guide 14 and the turn page roller assembly 5, and the page turning is completed. At this time, the uppermost page 40b that is flipped up is pulled out from the gap between the rear open guide 14 and the turn page roller assembly 5, and the turn page roller assembly 5 side of the rear open guide 14 is directed upward. Therefore, even if the flipped-up page 40b is pressed by its own weight, the page is not greatly bent in the direction opposite to the extraction direction, so that a strong load is not applied.

  Here, when it is determined from the output of the sensor 16 that the page has not been flipped up, the main control unit 35 performs a retry operation. That is, after the turn page roller assembly 5 is returned to the home position as described above, the feed motor 4 and the pressing feed roller 6 are rotated by driving the pulse motor 37 to advance the bankbook 40 by a predetermined amount. The advance amount is the same as the return amount when the passbook 40 is conveyed in the return direction in order to increase the peak of the bow-shaped page 40b, and the passbook 40 is returned to the page turning position again.

  Then, the page turning is performed by the above-described operation. When the bankbook 40 is conveyed in the return direction in order to increase the peak of the page 40b that has become an arcuate shape, it is conveyed more than the previous return amount, and the peak becomes higher. In this way, the page can be easily lifted. When turning the page of the passbook 40, the binding portion 40a is performed at the position on the rear open guide 14 side according to the insertion direction of the passbook described above. It is positioned on the front open guide 13 side, and the turn page roller assembly 5 is rotated in the opposite direction to the above description to turn the page. For this reason, in the front open guide 13 and the rear open guide 14, the ratio of pushing up the rear open guide 14 to turn the page is higher. Even when turning a cover having a thickness larger than that of the middle paper, the binding portion 40a is performed at a position on the rear open guide 14 side. During the page turning process described above, when the uppermost page 40b is lifted by the protruding portion 10a of the turn page roller assembly 5, the rear open guide 14 is pushed up, but the longer the distance to the fulcrum protrusion 14a is, The rear open guide 14 is easy to push up and the page is easy to flip up. On the other hand, the length of the ATP unit 19c is determined by the length of the entire apparatus. Therefore, the rear open guide 14 is lengthened and the front open guide 13 is relatively short, so that the ATP unit 19c is shortened and the accuracy of turning in the forward direction is not lowered. Even cardboard such as can be turned.
