PROBLEM TO BE SOLVED: To provide a technology capable of effectively restraining the deterioration in paste, without reducing productivity even to a continuous printing bookbinding job, by optimally setting the timing for resuming heating to the paste.SOLUTION: Time up to setting the paste of the temperature to the optimal temperature by being heated by the temperature of the paste and a heater, is stored in a storage part, and a residual printing time required up to completing printing is calculated based on the printing bookbinding job, and bookbinding of the present printing bookbinding job is completed, and when the printing bookbinding job exists in succession, electric power supply to the heater is stopped once, and when a predetermined time passes from when stopping the electric power supply, operation is controlled so as to resume the electric power supply to the heater. At this time, a control part is a bookbinding device for determining a predetermined time so as to become equal between the residual printing time and time up to setting the paste to the optimal temperature by being heated by the heater. |
