Abstract

PURPOSE:To prevent picture of all black from being transmitted in advance, by providing a monitor timer and a display use light emitting diode, detecting and displaying if a fluorescent lamp is deteriorated and the storage time is longer, and stopping the transmission. CONSTITUTION:At the storage time measurement, a controller 12 starts a measuring timer 13 and a monitor timer 14. If the storage time is short, the timers 13 and 14 are reset to start reading of the line. If the storage time is longer due to deteriorated fluorescent lamp, the monitor reset timer is not reset and time over is indicated. In this case, the controller 12 illuminates a display use light emittng diode 16 via a flip-flop 15 to display the deterioration of the fluorescent lamp and drives an FAX control circuit 17 and a line control circuit 18 and stops the transmission.
