Abstract

PURPOSE: To eliminate the necessity for applying the excessive force to a discharge tube, and to automate the assembling of a stroboscope part.
CONSTITUTION: A discharge tube 12 is inserted to through holes 18a, 18b, which are previously provided in a reflecting umbrella 13. When this reflecting umbrella 13, in which the discharge tube 12 is inserted in the through holes 18a, 18b, is fitted to a diffusion plate 14, both ends of the discharge tube 12 are supported by a pair of supports provided in the diffusion plate 14, and the discharge tube 12 is made to pressure-contact with the inner wall surface of the back side of the reflecting umbrella 13. Thereafter, the discharge tube 12 is slid slightly to be set at a predetermined position, and the assembling of a stroboscope part 10 is finished. Breakdown of the discharge tube 12 is thereby prevented.

【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、小型の簡易型ストロボ装置の発光部を組み立てる方法に関するものである。 The present invention relates to a method for assembling a light emitting portion of a small simplified flash device.

【0002】 [0002]

【従来の技術】ストロボ装置は、ストロボ光を被写体に向けて放出するストロボ発光部と、これを駆動するストロボ駆動回路とからなる。 BACKGROUND ART flash device is comprised of a flash emitter for emitting towards the flash light to the subject, a strobe drive circuit for driving the same. ストロボ発光部は、Xeガスを封入した細長いガラス製の放電管と、ストロボ光を反射させるアルミ製の反射傘と、この反射傘の前方に設けられた拡散板とからなる。 Flash projector is composed of a slender glass discharge vessel enclosing a Xe gas, and aluminum reflector for reflecting flash light, a diffusion plate provided in front of the reflector.

【0003】ストロボ装置の電源をONにすると、電気はメインコンデンサ及びトリガーコンデンサに充電され、放電管の両電極に印加される。 [0003] When ON the power source of the flash device, electricity is charged in the main capacitor and a trigger capacitor, it is applied to both electrodes of the discharge tube. カメラのシャッタ開放と同期してストロボ駆動回路のシンクロスイッチが閉じられと、トリガーコイルに電流が流れて数千ボルトから数万ボルトの非常に高い電圧まで昇圧される。 If synchro switch is closed the strobe drive circuit in synchronism with the shutter opening of the camera is boosted several thousand volts current flows in the trigger coil to a very high voltage tens of thousands of volts. この超高圧電圧がトリガー電極に印加されると、Xeガスがイオン化され、放電管内の抵抗が破れてメインコンデンサに蓄積されていた電荷が放電管の電極間で放電される。 When the ultra-high voltage is applied to the trigger electrode, Xe gas is ionized, a charge accumulated in the main capacitor torn resistance within the discharge tube is discharged between the electrodes of the discharge tube.
これによって、数百分の1〜数万分の1秒の閃光(ストロボ光)が放電管から放出される。 Thus, hundredths 1 to several tens of thousand fraction of a second flash (strobe light) is emitted from the discharge tube.

【0004】コンパクトカメラや使い切りカメラ等に搭載される小型の簡易型ストロボ装置の発光部では、トリガー電極はアルミ製の反射傘になっているので、放電管はその外周面を反射傘に圧接するように固定されている。 [0004] In the light emitting portion of the compact camera or single-use small simplified flash device mounted on the camera or the like, since the trigger electrode is in the reflector of aluminum, the discharge tube is pressed against the outer peripheral surface reflector It has been fixed so. このため、反射傘を爪止めする拡散板に放電管を支持する一対の支持部を形成して、この一対の支持部に放電管の両端部をそれぞれ当接させることで、放電管の外周面を反射傘の奥側内壁面に圧接している。 Therefore, by forming a pair of support portions for supporting the discharge tube to the diffuser plate to the pawl stop reflector, at both ends of the discharge tube that is brought into contact respectively to the pair of support portions, the outer peripheral surface of the discharge tube It is pressed against the back side of the inner wall surface of the reflection umbrella. このようなストロボ発光部を組み立てるには、まず拡散板に反射傘を爪止めした後、放電管を反射傘の奥側両側壁に設けられた貫通穴に挿入していた(特開平3−290634号公報)。 To assemble such a flash projector, after locking pawl the reflector First diffuser, the discharge tube had been inserted into a through hole provided on the back side both side walls of the reflector (JP-A 3-290634 JP).

【0005】 [0005]

【発明が解決しようとする課題】ところで、拡散板に形成された一対の支持部は、放電管を反射傘の奥側内壁面に圧接させる関係上、反射傘に形成された貫通穴の径を狭くする方向に突出されている。 [SUMMARY OF THE INVENTION Incidentally, a pair of support portions formed on the diffusion plate, the relationship for pressing the discharge tube to the back side inner wall surface of the reflector, the diameter of the through hole formed in the reflector It is projected in a direction to narrow. このように支持部によって狭くなった貫通穴に放電管を無理に挿入することは、ガラス製の放電管に余分な力を加えることになり、 Thus the through hole narrows by the supporting portion to forcibly insert the discharge tube, it will be added extra force to the discharge tube made of glass,
放電管の破損原因となっていた。 It has been a failure cause of the discharge tube. また、このため、ストロボ発光部の組立工程において放電管に加える力が微妙になるから、ストロボ発光部の組立工程を自動化することは困難であった。 Further, Therefore, since the force applied to the discharge tube in the assembly process of the flash emission part is delicate, it is difficult to automate the assembly process of the flash emitter.

【0006】本発明は、以上のような課題を解決するためになされたもので、放電管に余分な力を加える必要をなくし、ストロボ発光部の自動組立を可能にするストロボ発光部の組立方法を提供することを目的とするものである。 [0006] The present invention has been made to solve the above problems, eliminating the need to add an extra force to the discharge tube, the assembly method of the flash emitter which enables automatic assembly of the flash emitter it is an object to provide a.
