Claim:
A printing medium transferring apparatus comprising: a first guide member which includes a pinch roller and conveying roller; a driving source for moving the pinch roller between one position where the pinch roller is pressed to be in contact with the conveying roller and the other position where the pinch roller is separated from the conveying roller; the pinch roller for transferring a printing medium between the conveying roller and the pinch roller by being rotatably pressed to be in contact with the conveying roller, and which enables the pinch roller to be pressed to be in contact with, and separated from, the conveying roller while guiding a printing surface of the printing medium; a second guide member guiding the rear surface of the printing medium in a position facing the first guide member; detection means which is positioned in a printing medium transferring space formed between said first guide member and said second guide member and is able to detect a presence of the printing medium; and a holding member which includes a spur and an eject roller, wherein, by a power of said driving source, the spur is moved between one position where the spur is pressed to be in contact with the eject roller and the other position where the spur is separated from the eject roller, the spur for transferring the printing medium between the eject roller and the spur by being rotatably pressed to be in contact with the eject roller, and which enables the spur to be pressed to be in contact with, and separated from, the eject roller, wherein said second guide member is able to be moved, by the power of said driving source, between one position where said second guide member is close to said first guide member and the other position where said second guide member is far from said first guide member, and said detection means is able to be moved, by the power of said driving source, between one position where said detection means is within the printing medium transferring space and an other position where said detection means is separated from the printing medium transferring space.
