Claims

[Claims for Utility Model Registration] (1) A fixing device that fixes a toner image transferred to a sheet of paper, a paper ejection means that ejects the paper that has passed through the fixing device outside the apparatus, and the paper ejection means and the fixing device. The print head is placed in a paper transport path consisting of a paper guide plate between the ink ribbon and the printer, and is introduced between the paper guide plates by a moving means through an insertion opening formed at a proper position in a part of the paper guide plate, and the ink ribbon and the platen. a printing means that abuts the ink ribbon from behind the paper passed between the ink ribbon and the roller to print on the paper, and moves the printing head backward when not printing; and the insertion opening through which the printing head of the printing means moves up and down. a lid member for covering, and a drive means for supporting the lid member so as to be movable in conjunction with the operation of the moving means between a state in which the insertion port is closed and a state in which the print head is opened so as to be guided between paper guide plates. An image forming apparatus with a printing means, characterized by comprising: (2) a fixing device that fixes the toner image transferred to the paper; a paper ejecting device that ejects the paper that has passed through the fixing device to the outside of the device; and a paper guide plate between the paper ejecting device and the fixing device. A printing head is placed between the paper guide plates, and is introduced between the paper guide plates through an insertion opening formed at a proper position in a portion of the paper guide plate by a moving means, and is passed between the ink ribbon and the platen roller. a printing device that prints on the paper by contacting the ink ribbon from behind the paper and moves the printing head backward when not printing; a lid member that covers the insertion opening through which the printing head of the printing device moves up and down; and the lid member An image forming apparatus with a printing means, characterized in that the image forming apparatus includes a driving means for displacing the printing head into a state in which the insertion opening is closed and a state in which the printing head is opened so as to be guided between paper guide plates.
