Means for Solving the Problems In order to achieve the above-mentioned object, the cartridge setting mechanism according to the present invention includes a cartridge setting mechanism in which an opening is provided and a guide groove is formed in the side wall at a position away from the center thereof. a movable lid body for opening and closing the opening, a biasing means for biasing the movable lid body to take a position in which the opening is in an open state, and a movable lid body for opening and closing the opening; The cartridge is installed with a lid regulating member that restrains the movable lid in a position where the opening is closed, and when the cartridge is properly installed, The movable lid is provided with a protruding member that guides the case and displaces the lid regulating member to take a position in which the movable lid opens the opening.

F-effect In the cartridge setting mechanism according to the present invention configured as described above, the cartridge is not placed in a state in which its casing does not satisfy a predetermined front-back or top-bottom relationship, or does not have a predetermined orientation. If the case is to be attached in this state, the protruding member will not properly engage with the guide groove formed in the case, and the movement of the case will be restricted.

Therefore, the cartridge cannot reach the predetermined mounting position, and a situation in which the cartridge is incorrectly mounted is prevented.

On the other hand, when the cartridge is properly installed, the protruding member engages with the guide groove formed in the case, guides the case to a predetermined installation position, and closes the opening. The movable lid is constrained to the position where the movable lid is restrained by contacting the portion of the lid regulating member located within the guide groove, thereby displacing the lid regulating member, thereby causing the movable lid to be biased by the biasing means. The original position is to open the opening.

Therefore, with a relatively simple structure provided with a protruding member, it is possible to prevent the cartridge from being incorrectly installed, and to open the opening in the movable lid body when the cartridge is properly installed. Control to take the position will be performed reliably.
