Title: Discharge lamp lighting device
Inventor: MITA KAZUTOSHI
IPC: H05B41/24
Filed: 1994-09-28
Abstract: PURPOSE: To surely prevent the breakage of electronic parts of an inverter circuit and its peripheral circuit with a simple structure by connecting two diodes to the filament of a discharge lamp and detecting a half-wave current at the occurrence of a load short circuit to operate it as a safety circuit. CONSTITUTION: Diodes 13, 12 are connected to one end and the other end of the filament 18 of a fluorescent lamp 4. When a load short circuit is caused by the wiring error of the lamp 14, the high frequency current lighting the lamp 14 is made into a half-wave current by the diode 13. This half-wave current is carried to a half-wave detecting means 11 to operate the means 11 as a safety circuit, and never carried to the primary winding 7a of a saturable transformer 7 and a capacitor 20. Even when the load short circuit occurs, thus, the breakage of electronic parts of an inverter circuit and its peripheral circuit can be surely prevented.

Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To obtain a bar code reader which can set the exposure time of a linear sensor and the amplification factor of an amplifying circuit properly in terms of a bar code read.
