Abstract
PURPOSE: To provide a titled device which can prevent the occurrence of a trouble at a time when a type is imperfectly held or returned, by a method wherein photobeam makes contact with a type moving part below a type holding cylinder for type bar to verify a normal holding of or the presence of the type.
CONSTITUTION: A luminous element 7, a slit 8, a lens 9, and a collecting element 10 are positioned so that an optical path thereof is located paralleling a movement path of a type holding cylinder 4 and between a lower end of a type 6 perfectly held in the type holding cylinder 4 and an upper surface of a type panel 5. When the type is imperfectly held or returned arrival of light from the luminous element 7 to the collecting element 10 is disturbed, and the collecting element 10 does not generate an electric signal. The determines that a relative movement between a type bar 3 and the type panel 5 is impossible, and permits the indication of an alarm or the prohibition of the relative movement.
