Abstract: An image forming apparatus has an image forming section configured to form an image on an image receiving medium conveyed along a conveyance path from a cassette thereto, a diverted conveyance path connected to the conveyance path at a first point on the conveyance path upstream of the image forming section, a movable guide that is controlled to guide the image receiving medium along a first path that includes a second point on the conveyance path downstream of the first point or a second path that includes the diverted conveyance path, a group of sensors positioned to detect at least two positions of a leading edge of the image receiving medium before the image receiving medium is guided by the movable guide, and a controller configured to control the movable guide to guide the image receiving medium along the first or second path based on detection results of the sensors.

Abstract: A bonding device equipped with a heating block for heating, for instance, a lead frame upon which bonding is performed including vacuum suction nozzles, which are installed above the heating block so as to lift the lead frame, and an air-cylinder, which raises and lowers the vacuum suction nozzles. The lead frame is lifted from the heating block by the vacuum suction nozzles, thus being prevented from being overly heated by the heating block.
