Title:
FOREIGN MATTER WARNING DEVICE FOR DOOR PART
Document Type and Number:
Japanese Patent JPH01244922
Kind Code:
A
Abstract:
PURPOSE:To enable foreign matter for its capture or the like in a door part to be economically alarmed by respectively providing an alarm means acting unless light from a light emitting means is properly incident on a light receiving means and a power supply means supplying power to each means only when necessary. CONSTITUTION:A light emitting circuit 10 is connected to a light emitting diode 12. Light of the light emitting diode 12 is incident on a photodiode 14, and its output side connects a light receiving circuit 16. Further the light receiving circuit 16 connects its output side to an input side of an alarm circuit 18. A power supply circuit 20 is connected respectively to the above described circuits 10, 16, 18. Here the power supply circuit 20 is constituted so as to supply power when both an ignition switch and a door switch are placed in an on-condition. By this constitution, when a door part is in a condition catching foreign matter or half door, the alarm circuit 18 generates an alarm because of no proper incidence of light from the light emitting diode 12 on the photodiode 14.
