PURPOSE:To omit the trouble of printing of an identification mark, by printing the diagnostic identification mark onto a part of a sheet film in the carrying path through which the sheet film is carried. CONSTITUTION:When a card 13 is inserted to a prescribed position, a card detection switch 41 is switched to a contact B, and power is supplied to a relay 33 to excite the relay 44, and a switch 46 for exposure is closed to supply power to an exposure controlling circuit 47. When a start signal is sent, the identification signal of the card 13 is exposed to light on the surface of a sheet film through an optical system 10. An exposure end switch 48 is closed on the basis of the exposure end signal issued from the exposure controlling circuit 47, and as a result, power is supplied to a set coil 49 to excite the coil 49, and therefore, a relay switch 45 is closed, and consequently, the relay 44 is degaussed. Therefore, the switch 45 for exposure is opened, and power to the exposure controlling circuit 47 is broken; and even if the start signal is sent erroneously, exposure is not performed. When the card 13 is ejected from the prescribed position, the card detection switch 41 is switched to a contact A again to close a relay switch 45. |
