Sheet thermocompression apparatus and multifunction device

A sheet thermocompression apparatus for bonding a plurality of sheets to one another, and configured to be compatible with the sheets with a plurality of prescribed sizes, the sheet thermocompression apparatus comprising:

• a loading portion to be loaded with the bundle of sheets each including the adhesion layer formed thereon, the loading portion having an adjustment mechanism for adjusting a position of each of the sheets with the plurality of prescribed sizes in a longitudinal direction to a reference position;
• a thermocompression unit including (i) a pressing member pressing the bundle of sheets loaded on the loading portion in a loading direction of the sheets, a longitudinal direction of the pressing member is a direction along one edge of the sheets loaded on the loading portion, (ii) a heating source heating the pressing member, the heating source including a heat generator, (iii) a first temperature measuring sensor detecting a temperature of the heating source, and (iv) a second temperature measuring sensor detecting the temperature of the heating source, the second temperature measuring sensor arranged at a different position from that of the first temperature measuring sensor, the first temperature measuring sensor being arranged at a more distant position from the reference position, as compared with the second temperature measuring sensor;
• and
• a control portion controlling a heating value of the heat generator on the basis of a measurement result of the second temperature measuring sensor, and executing a temperature raising suppression operation of suppressing temperature raising of the heating source on the basis of a measurement result of the first temperature measuring sensor.

A multifunction device comprising:

• an image forming apparatus for forming an image on a sheet;
• and a post treatment apparatus including a sheet thermocompression apparatus for bonding a plurality of sheets to one another, and configured to be compatible with the sheets with a plurality of prescribed sizes, and a conveyance mechanism for conveying the sheets each including the image formed by the image forming apparatus thereon to the sheet thermocompression apparatus, wherein
• the sheet thermocompression apparatus comprises:
• a loading portion to be loaded with the bundle of sheets each including the adhesion layer formed thereon;
• and
• a thermocompression unit including (i) a pressing member pressing the bundle of sheets loaded on the loading portion in a loading direction of the sheets, a longitudinal direction of the pressing member is a direction along one edge of the sheets loaded on the loading portion, (ii) a heating source heating the pressing member, and (iii) a temperature measuring sensor arranged at a position not overlapping a minimum sheet with a minimum size of the prescribed sizes loaded on the loading portion in the loading direction, and detects a temperature of the heating source.

A multifunction device comprising:

• an image forming apparatus for forming an image on a sheet;
• and a post treatment apparatus including a sheet thermocompression apparatus for bonding a plurality of sheets to one another, and configured to be compatible with the sheets with a plurality of prescribed sizes, and a conveyance mechanism for conveying the sheets each including the image formed by the image forming apparatus thereon to the sheet thermocompression apparatus,
• wherein the sheet thermocompression apparatus comprises:
