Title: Burning display device
Inventor: MURAI EIJI
IPC: F23M11/04
Filed: 1985-01-16
Abstract: PURPOSE:To contrive the easy monitoring of display by a method wherein a gas pressure sensing conduit is connected to a gas passage located between a burner and a solenoid safety valve, and a display body is provided to be moved in correspondence with the gas pressure of the gas pressure sensing conduit. CONSTITUTION:Gas is flowed through a gas pressure sensing conduit 6 connected to a gas passage 4. The gas pressure is applied on a diaphragm 9 of a gas pressure sensing body 7. A display body 10 connected to the diaphragm 9 is moved upward. Therefore, during the extinguishment, for instance, a blue ground color ''extingwishment'' is displayed on the upper half part of a display part 12 through a display window 13, when a burning is started, a red ground color ''ignition'' is displayed on the lower half part of the display part. A burner 5 is burned as a catalyst mat under lower temperature burning condition. The distinguishment of a burning condition by monitoring the burner 5 is difficult to a user by the reason that the burner 5 is not red-heated. Consequently, the user can distinguish obviously that the burner is under burning condition or not by the display through the display window 13.

Abstract: PURPOSE:To enable detection of a non-moving condition such as a ribbon overload condition due to jamming and a ribbon end condition, by a construction wherein a film ribbon having a silver tape at a winding-starting part is wound around a payout reel, and a reflection-type photosensor is provided in the payout reel. CONSTITUTION:The film ribbon 3 having the silver tape 2 at the winding- starting part is wound around the payout reel 1. A reel guide shaft 7 is hollow, and the reflection-type photosensor 9 is disposed in the interior of the shaft 7. When light 9c from a light-emitting diode 9a is reflected by the silver tape 2 during rotation of the reel 1, the light 9c makes a photo-transistor 9b conductive, whereby an H signal is outputted to an output terminal, and when the light 9c is interrupted by the payout reel 1, and L signal is outputted, resulting in that a wave signal is obtained. When the rotation of the reel 1 is stopped due to jamming of the ribbon 3 or the like or when a ribbon end condition occurs, an H signal or an L signal is continuously outputted through an output terminal of the sensor 9. Such a signal is processed by a microprocessor, whereby the non-moving condition of the ribbon 3 can be detected.
