[0037]
First, the operation of the booklet printer 101 will be described with reference to FIG. The booklet is not shown in FIG. The booklet supplied from the booklet issuing unit 106 to the main conveyance path 103 is conveyed to the cover turning apparatus 1. The cover turning operation by the cover turning device 1 will be described in detail later, but the booklet with the cover turned is guided to the print head 108 and desired information is printed by the print head 108. Thereafter, the printed booklet is issued from the booklet issuing port 107.
[0038]
Next, the cover turning operation of the cover turning apparatus 1 will be described with reference to the flowcharts of FIGS. 1 to 11 and FIG.
[0039]
As shown in FIG. 1, the booklet 3 conveyed from the main conveyance path 103 of the booklet printer 101 to the cover turning apparatus 1 is conveyed in the booklet conveyance direction X by driving the conveyance motor 111 and rotating the conveyance rollers 7 to 10. Then, it is conveyed to a cover turning position where the turning roller 11 is arranged (step S1). Hereinafter, the rotation direction of the conveyance rollers 7 to 10 that convey the booklet 3 in the booklet conveyance direction is referred to as a normal conveyance direction. At this time, when the booklet 3 reaches the cover turning position, the transport rollers 7 to 10 are stopped. The timing of this stop is the drive pulse of the transport motor 111 after the booklet sensor 17 detects the front end of the booklet. It is determined by a method of counting. At this time, the position of the swing guide 14 is such that the booklet pressing surface 13 is parallel to the booklet conveying path 2 and a gap allowing the booklet 3 to be conveyed is formed between the booklet pressing surface 13 and the turning roller 11. This is the retreat position A. The retreat position A is a home position.
[0040]
In step S2, the booklet 3 is processed. Specifically, the swing guide motor 113 is driven by a predetermined drive pulse, and the swing guide 14 is turned from the retracted position A together with the lever 16 and the roller guide 19 around the guide shaft 15 as shown in FIG. It is inclined to the B position opposite to the direction. Thereafter, the swing guide motor 113 is driven to return the swing guide 14 together with the lever 16 and the roller guide 19 from the B position to the retracted position A. As a result, even if the cover 3a is in close contact with the next page, the close contact surface is loosened.
[0041]
Subsequently, the inflating process of the cover 3a is performed (S3 to S7). Steps S3 to S7 realize cover cover inflating processing execution means. Specifically, the swing guide motor 113 is driven by a predetermined drive pulse, and the swing guide 14 is tilted together with the lever 16 and the roller guide 19 to the advance position C in the cover turning direction as shown in FIG. Step S3). At this time, the swing guide 14 presses the booklet 3 against the roll roller 11 with the booklet pressing surface 13. That is, the cover 3 a of the booklet 3 is pressed against the turning roller 11.
[0042]
In this state, the transport motor 111 is driven by n1 pulses, and the transport roller 7 is rotated in the normal transport direction (direction a in FIG. 4) by n1 pulses (step S4). The state at this time is shown in FIG. As a result, the booklet 3 is conveyed toward the turning roller 11 at a portion sandwiched between the conveying rollers 7 and 8 with one end held by the turning roller 11. In other words, the booklet 3 is pushed from the portion sandwiched between the conveying rollers 7 and 8 toward one end that is held by the turning roller 11. At this time, the front cover 3a remains pressed against the page turning roller 11 by the frictional force between the turn roller 11 and the front cover 3a. As a result, the cover 3a is tightly curved. At this time, the frictional force between the cover 3a and the next page under the cover 3a is small, and slippage occurs between the cover 3a and the next page, and the next page under the cover 3a does not follow the curvature of the cover 3a. Therefore, as shown in FIG. 4, only the cover 3a swells. Even the cover sheet 3a which is swollen even a little becomes easy to swell thereafter.
[0043]
In this state, the turning roller 11 is rotated in the cover turning direction (direction b in FIG. 5) (step S5). In step S4, the cover sheet 3a is slightly swollen by the conveying roller 7, so that the turning roller 11 can further swollen the cover sheet 3a without slipping. The state at this time is shown in FIG. At this time, the cover 3a is further swollen against the strength of its own waist, so that the upstream shutter guide 21 is pushed upward by the cover 3a swollen upward and rotates upward. When the cover 3a is swollen to the position (c) in FIG. 5, the shutter guide 21 turns on the swollen detection sensor 23. When the bulge detection sensor 23 is turned on (Y in step S6), the turning roller motor 112 is driven by n2 pulses with reference to that point, and the turning roller 11 is further rotated by n2 pulses in the cover turning direction. Stop (step S7). In this state, the cover 3a is sufficiently inflated to the position (d) in FIG.
[0044]
Next, the next page dropping process is executed (step S8). Specifically, the swing guide motor 113 is driven by a predetermined drive pulse, and the cover sheet 3a swollen in the previous step is swung within a range in which the cover sheet 3a can be maintained in the pressure contact state with respect to the turning roller 11, as shown in FIG. The moving guide 14 is inclined to a fixed position (D position) on the retreat position A side. In this case, the pressing force by which the swing guide 14 rolls the booklet 3 and presses the booklet 3 is weaker at the D position than at the advance position C. Therefore, even if the page below the cover page 3a swells slightly due to friction with the cover sheet 3a swelled during the cover swell process, the swell is eliminated or reduced depending on the stiffness of the page.
[0045]
Subsequently, a cover flip-up process for jumping up the inflated cover 3a is executed (step S9). Step S9 realizes a cover-up process execution means. Specifically, the turning roller motor 112 is driven for n3 pulses, and the turning roller 11 is rotated in the cover turning direction (b direction in FIG. 7) by n3 pulses. As a result, as shown in FIG. 7, the cover sheet 3 a swollen in the previous step is flipped up by the turning roller 11. In that process, the shutter guide 21 is further pushed up by the cover sheet 3a that is flipped up. However, when the cover sheet 3a that is flipped up is straight and supported by the protrusion 20 of the roller guide 19, the shutter guide 21 returns downward. Then, it comes into contact with the cover 3a that is flipped up.
[0046]
Subsequently, the next page is returned (step S10). Step S10 realizes a next page return processing execution means. Specifically, the swing guide motor 113 is driven, and the swing guide 14 is tilted to the E position together with the lever 16 and the roller guide 19 as shown in FIG. The E position is a position slightly closer to the retreat position A side than the D position in the previous process. At this E position, the turning roller motor 112 is driven by n4 pulses, and the turning roller 11 is rotated by n4 pulses in the direction opposite to the cover turning direction (direction a in FIG. 8). As a result, the pages following the next page that have been swollen upward by the swelling process and the cover-up process of the cover sheet 3a so far are returned flat in the booklet transport direction.
[0047]
Subsequently, the swing guide motor 113 is driven by a predetermined drive pulse, and as shown in FIG. 9, the swing guide 14 is returned to the retracted position A which is the home position together with the lever 16 and the roller guide 19 (step S11). At this position, the cover 3a flipped up in the process so far is turned over (step S12). This step S12 realizes a cover turning process executing means. In this process, the turning roller 11 is rotated by a predetermined drive pulse in a direction opposite to the cover turning direction (direction a in FIG. 9), and the transport rollers 7 and 9 are rotated in the forward transport direction a by a predetermined drive pulse. Is made by rotating it. Thereby, as shown in FIG. 10, the booklet 3 is conveyed in the booklet conveyance direction X, and as shown in FIG. 11, the left cover 3a flipped up in the process is turned over to the right side. Subsequently, the process proceeds to the next process (step S13).
[0048]
Note that the cover turning device 1 of the present embodiment also serves as a page turning device, so that pages (medium pages) other than the cover 3a of the booklet 3 can be turned. Since the middle page turning operation is a known technique, a description thereof will be omitted.
[0049]
The processing in each of the above steps is performed by the CPU 115 executing the program written in the ROM 114.
[0050]
As described above, in the present embodiment, in the cover inflating process, first, after the cover 3a of the booklet 3 is slightly inflated by the conveying rollers 7 and 8 as the booklet conveying member, the turning roller 11 is driven from that state. Since the cover 3a of the booklet 3 is inflated, slippage of the turning roller 11 can be prevented, and the cover 3a of the booklet 3 can be reliably inflated. That is, the cover 3a of the booklet 3 can be reliably inflated by cooperating the conveying rollers 7 and 8 as the booklet conveying member and the turning roller 11.
