and is supported by the pressing block 04 and urged by a tension coil spring 05,
And the pressing block 04 is pressed by a member not shown.
Tape guide 0 that can be moved forward and backward to protrude from
Adhesive tape T with adhesive B on the top surface of 6,06
is placed.

The guiding member 07 also includes a guiding board 09 tiltably supported by a support shaft 08 on the machine frame side member of the apparatus main body, and a plurality of rollers 01 attached to the lower end of the guiding board 09.
0 and a compression coil spring 011 that biases the guide board 09 toward the center.

To perform bookbinding using the bookbinding device 01 having such a structure, a plurality of sheets of paper such as a manuscript, that is, a bound object P, is moved along the guide members 07, 07 against the elastic force of the compression coil spring 011. Insert the adhesive tape T on the tape guides 06, 06 into the heater 02 using its lower edge. By this operation, the adhesive tape T is bent into a shape that wraps the lower end of the bound product P in a U-shaped cross section, and then the left
When the right tape pressing means 03, 03 are driven close to each other, the tape guides 06, 06, which are already in contact with the adhesive tape T, are pressed against the pressing block 0.
As the blocks 4 and 04 move forward, they move backward relative to the pressure blocks 04 and 04 due to the biasing force of the tension coil spring 05, and finally the pressure blocks 0
4, 04 and tape guides 06, 06 strongly press the bound product P through the adhesive tape T. Thus, the molten adhesive B penetrates into the contact area between the adhesive tape T and the paper P, and the spine and side sealing (adhesion of the side surfaces) of the bound product are performed at the same time.

Problems to be Solved by the Invention However, in the bookbinding device 01, the distance between the roller 010 and the tape guide 06 is large, and when the bound workpiece P is inserted, its lower end is free, and the hem is closed as shown in the figure. Not only does it spread out,
Since the bend cannot be corrected, the lower end of the bound product P does not come into contact with the center of the adhesive tape T.
In addition, since the lower end in a free state is weak, it does not make sufficient contact with the contact tape T, which tends to result in poor binding.

Means and Effects for Solving Problems An object of the present invention is to provide a bookbinding apparatus that is less likely to cause bookbinding defects.

The bookbinding apparatus according to the present invention includes a heater located below, a pair of left and right tape pressing means with heaters located on the left and right sides above the heater and approaching and separating from each other; The left and right sides are located at the top, with a gap wider than the thickness of the bound products to be loaded, and are tilted downward so that the gap between them narrows, and the lower end side is supported so as to be able to swing from side to side. a pair of first guiding members, each extending downwardly along an extended surface of the first guiding member beyond the lower end of the first guiding member and slidable up and down along the first guiding member; a pair of left and right second guide members attached;
a pair of left and right connecting members pivotally connected to the heater-equipped tape pressure bonding means and the second guiding member; The guide member is slid upward, and the pair of left and right second guide members are slid downward as the pair of left and right heater tape crimping means are separated from each other. The tape pressure bonding means are separated from each other, and the pair of left and right second guide members move downward, and the second guide members extend sufficiently close to the adhesive tape placed along the tape pressure bonding means. In this state, when a bound product is inserted along the first guiding member and the second guiding member, and then the pair of left and right tape pressing means are brought close to each other, the tape pressing means moves through the connecting member. is transmitted to the second guide member, and the second guide member is slid upward along the first guide member and retreated.

Embodiments Hereinafter, embodiments of the present invention shown in FIGS. 1 to 4 will be described.

FIG. 1 shows a main part schematic diagram of the bookbinding apparatus 10, and the bookbinding apparatus 10 includes a heater 12 that extends in a direction perpendicular to the paper surface and is fixed to a machine frame side member, and a It is composed of tape pressure bonding means 14, 14 located above on the left and right and arranged so as to be able to approach and separate from each other, and guiding means 24, 24 located further above on the left and right. ing.

The tape pressure bonding means 14 extends in the direction perpendicular to the plane of the paper, like the heater 12, and includes a pressure block 16 which is provided with a rack 18 on the back surface that meshes with the drive pinion 19 and has a built-in heater, and the pressure block 16. When the pressing blocks 16, 16 are spaced apart as shown in FIG. When the pressing blocks 16, 16 are close together as shown in the figure, the tension coil spring 2
