As shown in FIG. 2, a large number of sheets a are inserted between the front and back covers 7a and 7b to be folded, and the electric heating element 9 and the electric heating element 9 are provided on the inner surface side of the spine cover 8 near the folding portion. And an adhesive 10 applied so as to cover the electric heating element 9, and electrodes 11 are provided at both ends of the electric heating element 9 so as to be exposed on the front surface side of the spine cover 8.

As shown in FIGS. 3 to 5, the bookbinding apparatus 3 has a plurality of ventilation slits b and a pair of box-shaped members 12 and 13 each having a vertical rib c formed therebetween, and the upper portion thereof is connected to the upper portion. Cooling from the outside air introduction hole e of the apparatus body 4 to the cooling means 2 is formed by forming a binder loading portion 14 serving as an insertion port d of the binder 6 and providing a heating means 15 on the lower side of the binder loading portion 14. Strictly speaking, it is provided inside the device in the course of the wind, facing the outside air introducing hole e.

The heating means 15 is attached to the terminal electrode 16 for energizing the electrode 11 exposed on the spine cover 8 of the binder 6 when the binder 6 is inserted into the loading portion 14, and the terminal electrode 16. And an electric circuit 17 of.
Further, a slide-type shutter 19 which is opened and closed by a driving means (a solenoid is shown as an example) 18 is provided at the binder insertion port d above the heating means 15,
Moreover, above the shutter 19, there is provided a binder detecting means 20 composed of a pair of light emitting and receiving devices.

The heating means 15 is composed of a terminal electrode 16 and an electric circuit 17 for energizing the electric heating element 9 provided on the inner surface side of the spine cover 8. The binder 6 coated with only the adhesive 10 on the side is bound for binding, and a heat source for heating and melting the adhesive 10 is provided on the binder loading part 14 side, and this heat source is the heating means 15. It is possible.

As shown in FIG. 6, a controller 21 for the heating means 15 and a controller 22 for the shutter driving means 18 are provided.
And a control unit 23 of the cooling unit 2 and a control unit 24 of the image forming apparatus.
Are both electrically linked to the control means 25, and a signal indicating whether or not the binder 6 has been detected from the binder detection means 20 is input to the control means 25. Interlocked to prevent simultaneous binding.

That is, in the non-image forming mode in which the driving of the image forming apparatus is stopped, when the binder detecting means 20 detects the binder 6, the driving means 18 opens the shutter 19 and the binder loading portion 14 To binder 6
The heating means 15 is energized for a predetermined time based on the binder detection signal, and the cooling means 2 is driven during the subsequent cooling process for a predetermined time, so that the binder loading part Although the heated binder 6 loaded in 14 is forcibly cooled, in this bookbinding mode, a control mode in which the image forming apparatus cannot be driven is adopted. When the binder detecting means 20 detects that the binder 6 is pulled out from the binder loading portion 14, the driving means 18 is driven so as to close the shutter 19.

On the other hand, in the image forming mode in which the image forming apparatus is driven, even if the binder detecting means 20 detects the binder 6, the shutter driving means 18 is not operated, that is, the image forming operation is performed. Under the mode, a control mode that disables the bookbinding mode is adopted.

According to the above construction, in the non-image forming mode, as shown in FIGS. 2 and 7, the aligned paper sheets a are made to have their edges abutted against the adhesive 10 and the binder. When the binder 6 is sandwiched between them and brought close to the binder insertion port d, the shutter 19 closing the binder insertion port d is opened.

Then, when the binder 6 is loaded into the binder loading portion 14 through the binder insertion port d, the electrode 11 of the electric heating element 9 on the binder 6 side is loaded into the binder loading portion 14.
By contacting the terminal electrode 16 on the side, the electric heating element 9 is heated for a predetermined time (for example, 60 seconds).

As a result, the adhesive 10 is heated and melted, the adhesion of the sheet a to the inner surface of the back cover 8 of the binder 6 is started, and when the heating process for a predetermined time is completed, the cooling means 2 is driven for a predetermined time. The cooling step (for example, 30 seconds) is started, and the binder 6 in the stationary state, which is still loaded in the binder loading section 14, is forcibly cooled.

When the forced cooling process is completed, for example, a lamp is turned on to indicate the completion of the cooling process, and the operator simply loads the binder 6 with the sheet a set in the loading section 14. Then, by waiting for the passage of time, it is possible to obtain a booklet with reliable adhesion and a constant finish quality.

Instead of driving the cooling means 2 for a predetermined period of time, the cooling means 2 may be stopped in response to the extraction detection signal of the binder 6 from the binder detection means 20.
