  Further, in FIG. 3, the winding roller 17 coaxially arranged with the driven roller 28b of the intermediate conveying roller pair, the movable guide 29, the driving roller 31a of the rear conveying roller pair, the driven roller 31b, and these three roller pairs are formed. A push-up member 24 that is disposed between the driving roller 28a of the intermediate carrying roller pair and the driven roller 31b of the back-side carrying roller pair below the booklet carrying path is shown.

  FIGS. 4A to 4G are operation state diagrams sequentially showing page turning operations in the page turning mechanism having the above-described configuration. 4 (a) to 4 (g), the same numbers as those in FIG. 3 are assigned to the portions necessary for the description.

  In the following description, the driving roller and the driven roller are not described. For example, in the case of the driving roller 25a and the driven roller 25b of the suction / discharge transport roller pair, the suction / discharge transport roller pair 25a and 25b is simply used. It describes.

  First, in FIG. 4 (a), the booklet 33 carried in (sucked) by the suction / discharge transport roller pairs 25a and 25b as indicated by the arrow a, the front page 33a of the spread page is changed to the rear transport roller pair 31a and The rear page 33b of the double-page spread is conveyed to the turning position of the turning roller 17 as shown in FIG.

  Here, as shown in FIG. 4B, all the three roller pairs are stopped, the gripping portions of the intermediate conveyance roller pairs 28a and 28b are opened, and the movable guide 29 is rotated upward to move on the conveyance path. To release the regulations.

  Further, the push-up member 24 is driven and rotated by the push-up roller 32 to push up the rear page 33b of the booklet 33 by a height h from below. This push-up height h is 60% lower than the normal push-up height. The reason will be described in detail later.

  Next, as shown in FIG. 4C, the turning roller 17 rotates approximately 260 degrees in the counterclockwise direction indicated by the arrow b, and slides to the rear end of the uppermost page 33b-1 of the rear page 33b of the booklet 33. In contact with it, the uppermost page 33b-1 is expanded upward. At this time, the turning roller motor 16 rotates while generating cogging at a speed of 40%, which is lower than the rotation speed (hereinafter simply referred to as normal rotation speed) performed by the conventional turning mechanism. The reason will be described in detail later.

  Next, as shown in FIG. 4 (d), the turning roller 17 stops and the push-up member 24 returns from the booklet push-up position to the home position shown in FIG. 4 (a). As a result, the rear page 33b of the booklet 33 returns to the horizontal position, and the rear end of the uppermost page 33b-1 lowered accordingly is pressed against the turning roller 17 by the repulsive force of bending.

  Subsequently, as indicated by an arrow c in FIG. 4 (e), the turning roller 17 rotates approximately 120 degrees counterclockwise from the stop position, and the rear end of the uppermost page 33b-1 is lifted and stopped. To do. The rear end of the uppermost page 33b-1, which has been released from being bent up, rides on the stopped turning roller 17.

  Next, as shown in FIG. 4 (f), the intermediate conveyance roller pairs 28a and 28b close the gripping portion and sandwich the booklet 33. Subsequently, the suction / discharge conveyance roller pairs 25a and 25b, the intermediate conveyance rollers All the transport roller pairs of the pair 28a and 28b and the back side transport roller pair 31a and 31b rotate in the booklet discharge direction indicated by the arrow d.

  As a result, while the booklet 33 is being discharged, the uppermost page 33b-1 riding on the stopped turning roller 17 is pushed up and pushed down by the driven roller 28b of the intermediate conveying roller pair together with the discharge movement of the booklet 33. Overlapping the front page 33a of the spread page.

  Thereafter, as shown in FIG. 4G, the booklet 33 is sequentially discharged out of the turning mechanism, the movable guide 29 returns from the upper restriction release position to the restriction guide position, and the turning roller 17 is flipped up. It rotates about 20 degrees in the clockwise direction indicated by the arrow e from the stop position, and returns to the home position before the start of turning. This completes the page break.

  Here, the reason why the push-up member 24 shown in FIG. 4 (b) pushes the rear page 33b of the booklet 33 at a height of 60% lower than the normal push-up height, and the turning roller 17 shown in FIG. 4 (c). The reason for rotating while generating cogging at a speed of 40%, which is lower than the normal rotation speed, will be described.

  First, the inventor decided to investigate the correlation between the success rate of the hitting, the occurrence rate of the tampering in the successful hitting, the pushing-up height, and the rotation speed of the hitting. It should be noted that the success rate of tapping and the occurrence rate of tampering are contradictory information, and therefore, the tampering occurrence rate is described by replacing it with the tampering prevention rate (success rate of normal tapping). As a result, all of the information becomes the success rate of resentment. For this experiment, three types of booklets were prepared: a booklet generally used in the past (hereinafter simply referred to as a normal booklet) and a sample 1 and sample 2 booklet.

  The normal booklet is usually a booklet as it is (hereinafter also referred to as a passbook or medium). Sample 1 is a specimen in which a dent is provided so as to extend over a plurality of pages, and it is difficult to separate pages by being caught between overlapping pages when turning pages. Sample 2 is a specimen in which the coefficient of friction between the next page of the page to be turned and the next page is lowered so that the user can easily move the page when turning the target page.

  In this way, for a normal state medium and two types of specimens crafted so that tampering is likely to occur, the pushing-up height, the success rate of tapping, and the prevention rate of tampering during success FIG. 5 (a) to FIG. 5 (b) show the results of examining the relationship with the (normal success rate).

  Fig. 5 (a) shows the success rate of the roll when the rotational speed of the roll is a normal speed and the push-up height is changed variously, and the prevention rate of the successful tapping (success rate of normal roll). It is the chart which listed the measured data. The chart shows the push-up height at the left end, from 20% to 160% in increments of 20%, where the current (normal) height is 100%. For example, the normal height is set to 8.5 mm.

  The success rate of the normal medium, sample 1 and sample 2 is recorded in the left half of the column following the right side, and the normal medium, sample 1 and sample 2 are successfully turned over in the right half. The prevention rate (success rate of normal strike) is recorded.

  FIG. 5B is a graph of the data in the left half of the chart of FIG. 5A. The normal medium is indicated by M-S1, the sample 1 is indicated by S1-S1, and the sample 2 is indicated by S2-S1. The horizontal axis shows the height from 20% to 160%, and the vertical axis shows the success rate of the turn from 0 to 100%. In addition, the success of a hit is regarded as a success if it is drowned regardless of whether or not it is accompanied.

  FIG. 5 (c) is a graph of the data in the right half of the chart of FIG. 5 (a). In this case, the normal medium is indicated by M-S2, the sample 1 is indicated by S1-S2, and the sample 2 is indicated by S2-S2. ing. The horizontal axis indicates the height from 20% to 160%, and the vertical axis indicates the tampering prevention rate (success rate) during the successful roll from 0 to 100%. FIG. 6 (a) is a graph showing the two graphs of FIG. 5 (b) and FIG. 5 (c) on one sheet. FIG. 6 (b) is a graph of FIG. 5 (b) and FIG. 5 (c). ) Is a graph obtained by combining (accumulating) the two graph data, and is a graph showing the overall success rate of the hitting when both situations are performed. From the three types of data shown in FIG. 6B, it can be seen that the success rate of beat is high in the range of 60% to 100%.

  5 (a), (b), and (c), with regard to the tampering prevention rate, with normal media, the tampering prevention rate (success rate of normal tapping) is 100% at a height of 100% or less. When the result of 2 is observed, it is understood that the tampering prevention rate is high up to a height of 60% or less, but the tampering prevention rate (success rate of normal tapping) rapidly decreases at 60% or more.

  However, if it becomes 100% or less, the success rate of the hit also decreases. Still, the normal media is 60% in height and the success rate is 70%, which is a relatively high value. To maintain a high tampering prevention rate that can cope with changes in paper quality, the height is 60%. It can be considered that it should be based on ˜100% (5 mm to 8.5 mm).

  Next, with respect to the medium in the normal state and the two types of samples crafted so as to be easily tampered with, the rotation speed of the turning roller motor 16 for rotationally driving the turning roller 17, FIGS. 7 (a) to 8 (b) show the results of examining the relationship between the success rate and the success rate of successful tampering (success rate of normal hitting).

  Fig. 7 (a) shows the actual success rate of the roll when the push-up height is set to the normal height and the motor rotation speed is changed, and the success rate of normal tapping (success rate of normal strike). It is the chart which listed the data which was done. The chart shows the motor rotation speed at the left end from the normal rotation speed to 100%, from 20% to 160% in increments of 20%. For example, the normal rotation speed is 16 rad / s.

  The success rate of the normal medium, sample 1 and sample 2 is recorded in the left half of the column following the right side, and the normal medium, sample 1 and sample 2 are successfully turned over in the right half. The prevention rate (success rate of normal strike) is recorded.

  FIG. 7B is a graph of the data in the left half of the chart of FIG. 7A. The normal medium is indicated by M1-S1, the sample 1 is indicated by S1-S1, and the sample 2 is indicated by S2-S1. The horizontal axis represents the motor rotation rate from 20% to 160%, and the vertical axis represents the turnover success rate from 0 to 100%. In this case as well, the success of the hit is determined to be successful regardless of the presence or absence of the carry.

  FIG. 7 (c) is a graph of the data in the right half of the chart of FIG. 7 (a). In this case, the normal medium is indicated by M-S2, the sample 1 is indicated by S1-S2, and the sample 2 is indicated by S2-S2. ing. The horizontal axis indicates the motor rotation speed from 20% to 160%, and the vertical axis indicates the tampering prevention rate (success rate for normal hitting) during the successful hitting from 0 to 100%. FIG. 8 (a) is a graph showing the two graphs of FIG. 7 (b) and FIG. 7 (c) on one sheet. FIG. 8 (e) is a graph of FIG. 7 (b) and FIG. 7 (c). ) Is a graph obtained by combining (accumulating) the two graph data, and is a graph showing the overall success rate of the hitting when both situations are performed. From the three types of data shown in FIG. 8B, it can be seen that the success rate of beat is high in the range of 20% to 60%.

  7 (a), (b), and (c), with regard to the tampering prevention rate (success rate of normal tapping), the normal medium has a motor rotation rate of 100% or less, but the prevention rate is 100%. Observing the results of No. 1 and Sample 2, it can be seen that the occurrence rate of tampering rapidly decreases at a motor rotation rate of 60% or less.

  Here, regardless of the occurrence rate of tampering, the success rate of turning is maintained at 100% regardless of the normal medium, sample 1 and sample 2 when the motor rotation rate is 120% or less. In order to maintain a high tampering prevention rate (success rate of normal strike), the motor rotation rate should be based on 20 to 60% (3.2 rad / S to 9.6 rad / S). You can see.

  Cogging depends on the characteristics of the motor, but in the motor of this example, the cogging is normally applied to the rolling roller during turning, which generates cogging at a rotation speed ratio of 60% (here, 9.6 rad / S) or less. The vibration contributes to the function of separating the pages to be carried and separating only the top page.

  Also, based on the basics described above, the method of executing the page turning by combining the pushing height of 60% and the motor rotation rate of 40% gives priority to the reduction of the occurrence rate of the tampering so that it can cope with the change in paper quality, and the page has been successfully turned. Since the rate is somewhat sacrificed, the success rate is reduced for normal media. In this case, it can be improved by changing the push-up height at the retry stage.

  In addition, in the Example mentioned above, a various change can be added in the range which does not deviate from the summary of embodiment.

  The present invention can be used for a booklet printing apparatus provided with a page turning mechanism that reduces as much as possible without changing the conventional simple configuration when a booklet consisting of a plurality of pages is changed.
