DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes an apparatus main body of a bookbinding apparatus. An apparatus main body 1 has an insertion portion 3 for bookbinding paper (a stack of a plurality of bookbinding papers) 2, a cartridge holder 4 for housing and holding a tape cartridge 5, and a cross section for holding a spine tape 4 pulled out from the cartridge holder 4. In addition to the U-shaped straight guide groove 6, as shown in FIG. 2, a receiving member 7 for receiving the bookbinding paper 2 inserted from the insertion portion 3 shown in FIG.
(Not shown) for guiding and supplying the guide groove, the guide groove 6
To move the protruding portion of the backing tape a into the binding paper 2
There is provided a first pressing means 8 for pressing against one side portion, a second pressing means 9 for moving while pressing the back adhesive tape a against another portion, and the like. The tape cartridge 5 is housed inside the cartridge holder 4, and the tape cartridge 5 houses a back-adhering tape a wound in a roll shape. As shown in FIG. 12, two pieces of release paper 10 are adhered to the adhesive surface a1 of the back adhesive tape a, one half in the longitudinal direction and one in the other side.

Here, the operation of the bookbinding apparatus will be briefly described. As shown in FIG. 3, the backing tape a is supplied and held in the guide groove 6, and cut to fit the size of the bookbinding paper 2. When the guide groove 6 is moved,
As shown in FIG. 4, the protruding portion of the backing tape a is moved onto the end of one side of the bookbinding paper 2 set on the receiving member, and the backing tape a is further moved by the first pressing means 8. To the adhesive surface a of the backing tape a
1 is pressed against and adhered to the surface of the bookbinding paper 2. Thereafter, as shown in FIGS. 5, 6, and 7, the second pressing means 9 moves along the spine of the bookbinding paper 2 while squeezing the spine tape a along the spine. Thus, it moves along the other side of the bookbinding paper 2 together with the receiving member 7, and the remaining part of the backing tape a is bonded to this part. When the backing tape a is supplied to the guide groove 6, one release paper 10 is peeled off, and when the second pressing means 9 moves on the back of the bookbinding paper 2, the other half 10 is peeled off. (See FIG. 7).

As shown in FIGS. 1 and 2, the cartridge holder 4 and the tape cartridge 5 are opposed to each other in the vicinity of one back side of one side of the guide groove 6 when viewed from the insertion portion 3 of the bookbinding paper 2. . FIG. 1 shows a comparison between the above arrangement and the arrangement of tape cartridges in a conventional apparatus.
As shown at 0, the shape of the tape cartridge 5 is the same as in the conventional case, and is formed in a trapezoidal shape, and the acute-angled portion 5a serves as an outlet for the backing tape a. However, the conventional tape cartridge 5 is arranged in the storage portion 23 outside the apparatus main body 1, and the back adhesive tape a is drawn straight out from the outlet 5 a and supplied to the guide groove 6 of the apparatus main body 1. Was. By rotating the tape cartridge 5 as shown by the arrow A, the mounting space S1 of the storage portion of the conventional tape cartridge 5 is eliminated.
By rotating the tape cartridge 5, the space S2 is eliminated and the tape cartridge 5 is housed inside the apparatus main body 1. Therefore, the whole configuration could be made compact by the above configuration.

Further, inside the tape cartridge 5, a back adhesive tape a is wound and housed so that the adhesive surface a1 faces outward (see FIG. 12). This is opposite to the winding direction of the conventional back adhesive tape a. After the back affixed tape a is led out from the outlet 5a, it is turned into a U-shape with respect to the guide groove 6 and supplied.

Next, as shown in FIG. 2, the cartridge holder 4 has a take-out portion 4a (disposed on the front side of the cartridge holder 4) of the backing tape a and an internal position (shown by a solid line) of the apparatus main body 1. It is provided to be rotatable with respect to an external inclined position (indicated by a dashed line) of the apparatus main body 1. That is, a pair of left and right triangular protrusions 11 is formed on the side of the cartridge holder 4 opposite to the take-out portion 4 a of the tape cartridge 5, and one end of an arm 12 is pivotally mounted on the base end of the side piece 11. The other end of the arm 12 is supported by a fixed shaft 15 fixed to both side walls 14 of the apparatus main body 1. The moving shaft 1 is provided at the tip of the side piece 11.
7 are attached, and both ends of the moving shaft 17 are slidably engaged along guide grooves 18 formed substantially perpendicularly to both side walls 14 of the apparatus main body 1. The upper end of the guide groove 18 is bent at a substantially right angle inward, and the lower end is inclined inward.

In the above configuration, during normal use, the back affixed tape a is drawn out from the outlet 5a of the tape cartridge 5 as shown in FIG. When the backing tape a is consumed and needs to be replaced with a new one, the cartridge holder 4 may be pulled out as shown in FIG. Thereby, the moving shaft 17 moves downward along the guide groove 18, and accordingly, the cartridge holder 4 moves around the fixed shaft 15 so as to draw a circle having the length of the arm 12 as a diameter, It stops in a substantially inclined posture outside the apparatus main body 1. In this state, the take-out portion 4a on the front side of the cartridge holder 4 faces outward, so that it can be opened to easily and reliably replace the back adhesive tape a. After replacement, cartridge holder 4
5 may be pushed up and further pushed inward to engage the receiving portion 13 provided with the guide groove 6. The same is true when the back affixed tape a is attached for the first time.

As described above, since the cartridge holder 4 is housed in the apparatus main body 1, the whole can be made compact, and the cartridge holder 4 can be moved to the outside so that the tape Mounting and replacement can be done easily as before,
Operability is also good. In addition, since the guide grooves and other operation mechanisms may be the same as those in the related art, the cost for improvement can be reduced.
