A machine for inspecting a printed circuit board comprising a transfer device (1), a loading device (2), an inspecting device (3) and an unloading device (4). They are arranged as shown in the drawing. The transfer device (1) comprises a first transfer device (5) for transferring a printed circuit board (P) so as to image the printed circuit board by a line sensor (61) and a second transfer device (6) for transferring the printed circuit board (P) after the imaging. The first transfer device (5) has an inclined plate (9) which is oriented in the direction where the printed circuit board (P) is transferred and inclined with respect to a reference surface at a predetermined angle ( theta ), the entire plate surface of the printed circuit board (P) is set along the inclined plate (9), and the printed circuit board (P) is placed on a transfer table (31) in this state, and forcedly transferred. La présente invention concerne un appareil servant à examiner les cartes à circuits imprimés. Cet appareil comprend un module de transfert (1), un module de chargement (2), un module d'examen (3) et un module de déchargement (4). Pour l'agencement de ces modules entre eux, se reporter à la figure. Le premier poste de transfert (5) du module de transfert (1) prend la carte à circuit imprimé (P) et la soumet à par une ligne de détection (61), un second poste de transfert (6) assurant le transfert de la carte à circuit imprimé (P) après l'imagerie. Le premier poste de transfert (5) comporte un plan incliné (9) orienté dans l'axe du transfert de la carte à circuit imprimé (P), et formant par rapport à la surface de référence un angle défini ( theta ). La totalité de la surface de la carte à circuit imprimé (P) repose sur le plan incliné (9). Arrivé sur une table de transfert (31), la carte à circuit imprimé (P) est emmenée mécaniquement.
