理判断部とを具備してなる記録計の紙無し検出装置。A light emitting section and a light receiving section arranged to receive light reflected by a recording paper in a recorder, a light emitting element driving section that switches and drives the light emitting section so that the amount of light emitted is different, and light receiving from the light receiving section. There is a light reception/non-reception determining section that receives an output signal indicating the amount of light received and outputs a determination signal by determining that the amount of light received is greater than or equal to the amount of light received, and that no light is being received if it is less than that, and synchronizes the determination signal of this light reception/presence determining section with the switching of the light emitting section. and a latch circuit section that stores each, and the memory contents of this latch circuit section are read out.When no light is received for all the judgment signals, it is judged that there is no paper, and when all the judgment signals are received, it is judged that there is paper. A paper-out detection device for a recorder, further comprising a logic determining section that determines that there is an abnormality in a detection system including a light emitting section and a light receiving section when the respective judgment signals at different amounts of emitted light are different.
