PURPOSE: To surely position a card at a loading part and to accurately transmit data by forming the aperture shape of the loading part in such a way that one of confronting aperture sides is set shorter a little than the card and the other longer a little than the card, and setting the protrusive quantity of an edge part at a side where a pressing means is provided at two or more times that of another edge part.

CONSTITUTION: This device is equipped with the loading part 8 which can load a data memo card 7 having an input key for data in such a way that it can be mounted/ dismounted, and the aperture shape of the loading part 8 is formed in such a way that one of the confronting aperture sides is set shorter a little than the card 7 and the other longer a little than the card. The edge part 4a of the confronting aperture side on the other side is formed protrusively, and the pressing means 11, 12 which perform the positioning of the card 7 in a parallel direction for the bottom plane of the loading part 8 are provided, and the protrusive quantity of the edge part at a side where the pressing means 11, 12 are provided is set at two or more times the protrusive quantity of another edge part. In such a way, it is possible to surely perform the positioning of the card 7 for the loading part of a facsimile equipment main body and the data is accurately transmitted.
