Abstract

Two laminating films are placed on an upper paper feeding cassette and a manual feed tray, respectively, and a medium to be laminated is placed on a lower paper feeding cassette. These two laminating films are once stopped by coming in contact with a standby conveyance roller pair in a stopped state and the lamination target medium is stopped by being interposed between the two laminating films. Then, the two laminating films and the lamination target medium are integrally conveyed to a fuser by the standby conveyance roller pair and subjected to lamination processing by being heated and pressurized by the fuser.

First claim

What is claimed is:

1 . A laminating apparatus comprising:
a first accommodation section which accommodates a first laminating film; a second accommodation section which accommodates a second laminating film; a third accommodation section which accommodates a lamination target medium; a heating and pressurizing section which is provided on a lower flow side with respect to a standby conveyance roller pair in a conveying direction; and a conveying section which (i) conveys the first laminating film supplied from the first accommodation section and the second laminating film supplied from the second accommodation section until a tip end of the first laminating film and a tip end of the second laminating film come in contact with the standby conveyance roller pair, with the standby conveyance roller pair being stopped, (ii) conveys the lamination target medium supplied from the third accommodation section to an area between the first laminating film and the second laminating film in contact with and stopped by the standby conveyance roller pair, and (iii) drives the standby conveyance roller pair to convey the first laminating film, the second laminating film, and the lamination target medium interposed between the first laminating film and the second laminating film to the heating and pressurizing section.

2 . A laminating apparatus comprising:
a first conveyance path for conveying a first accommodated object placed on a first accommodation section to a standby conveyance roller pair; a second conveyance path for conveying a second accommodated object placed on a second accommodation section to the standby conveyance roller pair; a third conveyance path for conveying a third accommodated object placed on a third accommodation section to the standby conveyance roller pair; a heating and pressurizing section which is provided on a lower flow side with respect to the standby conveyance roller pair in a conveying direction; and a control section which (i) conveys the first accommodated object, the second accommodated object, and the third accommodated object to the standby conveyance roller pair by the first conveyance path, the second conveyance path, and the third conveyance path, respectively, with the standby conveyance roller pair being stopped, in such a manner that at least a tip end of the second accommodated object is interposed between the first accommodated object and the third accommodated object, (ii) drives the standby conveyance roller pair after conveying the first accommodated object, the second accommodated object, and the third accommodated object to the standby conveyance roller pair, and (iii) conveys the first accommodated object, the third accommodated object, and the second accommodated object interposed between the first accommodated object and the third accommodated object to the heating and pressurizing section.

3 . The laminating apparatus according to claim 2 , wherein the first conveyance path conveys the first accommodated object placed on the first accommodation section to the standby conveyance roller pair such that a surface of the first accommodated object opposing a placement surface of the first accommodation section is oriented to a predetermined direction when the first accommodated object passes through the standby conveyance roller pair,
wherein the second conveyance path conveys the second accommodated object placed on the second accommodation section to the standby conveyance roller pair such that a surface of the second accommodated object opposing a placement surface of the second accommodation section is oriented to a same direction as the predetermined direction when the second accommodated object passes through the standby conveyance roller pair, and wherein the third conveyance path conveys the third accommodated object placed on the third accommodation section to the standby conveyance roller pair such that a surface of the third accommodated object opposing a placement surface of the third accommodation section is oriented to a direction opposite to the predetermined direction when the third accommodated object passes through the standby conveyance roller pair.

4 . The laminating apparatus according to claim 2 , wherein the control section conveys the first accommodated object and the third accommodated object to the standby conveyance roller pair before conveying the second accommodated object to the standby conveyance roller pair.

5 . The laminating apparatus according to claim 2 , wherein the second conveyance path comprises a detection section which detects the tip end of the second accommodated object serving as a lamination target object, and
wherein the control section starts driving of the standby conveyance roller pair after a predetermined amount of time has elapsed from when the tip end of the second accommodated object is detected by the detection section.

6 . The laminating apparatus according to claim 2 , wherein the first accommodation section is arranged higher than the second accommodation section.

7 . An image forming apparatus comprising:
a switching section which switches between a printing mode and a laminating mode; a first conveyance path for conveying a first accommodated object placed on a first accommodation section to a standby conveyance roller pair; a second conveyance path for conveying a second accommodated object placed on a second accommodation section to the standby conveyance roller pair; a third conveyance path for conveying a third accommodated object placed on a third accommodation section to the standby conveyance roller pair; a control section which drives the standby conveyance roller pair after conveying the first accommodated object, the second accommodated object, or the third accommodated object to the standby conveyance roller pair; and a fixing section which is provided on a lower flow side with respect to the standby conveyance roller pair in a conveying direction, wherein the control section, when a current mode is switched to the laminating mode by the switching section, (i) conveys the first accommodated object, the second accommodated object, and the third accommodated object to the standby conveyance roller pair by the first conveyance path, the second conveyance path, and the third conveyance path, respectively, with the standby conveyance roller pair being stopped, in such a manner that at least a tip end of the second accommodated object is interposed between the first accommodated object and the third accommodated object, (ii) conveys the first accommodated object, the second accommodated object, and the third accommodated object to the standby conveyance roller pair, and then (iii) conveys the first accommodated object, the third accommodated object, and the second accommodated object interposed between the first accommodated object and the third accommodated object to the fixing section.

8 . The image forming apparatus according to claim 7 , wherein the first conveyance path conveys the first accommodated object placed on the first accommodation section to the standby conveyance roller pair such that a surface of the first accommodated object opposing a placement surface of the first accommodation section is oriented to a predetermined direction when the first accommodated object passes through the standby conveyance roller pair,
wherein the second conveyance path conveys the second accommodated object placed on the second accommodation section to the standby conveyance roller pair such that a surface of the second accommodated object opposing a placement surface of the second accommodation section is oriented to a same direction as the predetermined direction when the second accommodation section passes through the standby conve
