Abstract

PURPOSE:To ensure an early and automatic detection for a fault of recording due to the shortage of ink, etc., by setting a detecting means consisting of at least a pair of a light emitting element and a photodetector in the vicinity of the tip of a ball pen. CONSTITUTION:A detecting means consisting of at least a pair of a light emitting element E and a photodetector D is provided at an area close to the tip 1' of a ball pen. The recording paper 5 to which the recording is carried out by means of the ball pen is irradiated by the light radiated from the element E. The reflected light is detected by the detector D. Thus the presence or absence of the recording on the paper 5 is detected.
