ABSTRACT:
A strobo unit is disclosed for use in association with a camera provided with a changeover switch operating between an automatic exposure mode and a flashlight mode and normally placed in the automatic exposure mode, and with an accessory shoe connected with the X contacts internally housed within the camera, the switch and the shoe being located on adjacent exterior surfaces of the camera. The strobo unit comprises a mounting baseplate connected with the strobo unit in a manner to permit an angular movement therebetween and having a fixture which is adapted to engage the accessory shoe, a normally closed power switch mounted on an outer wall surface of the strobo unit which is adapted to engage the mounting baseplate, and a detent for releasably securing the strobo unit in one of three positions when it is mounted on the camera by engaging the fixture of the baseplate with the accessory shoe, said three positions including a first position in which the exterior surface portion of the strobo unit on which the power switch is mounted bears against the mounting baseplate, a second position in which another exterior surface portion of the strobo unit bears against an exterior surface portion of the camera on which the changeover switch is mounted as the strobo unit is angularly moved from the first position, and a third position located intermediate the first and the second position. When the strobo unit is located in its first position, the changeover switch is maintained in the automatic exposure mode while the power switch is opened as a result of the engagement of the mounting baseplate therewith, thereby enabling an automatic exposure mode of photographing in which a strobo unit is not used. In the second position of the strobo unit, it operates the changeover switch to switch it to the flashlight mode, and the closed power switch enables a flashlight mode for photographing. In the third position of the strobo unit, the changeover switch is again thrown to the automatic exposure mode, and the closed power switch enables an automatic exposure mode of photographing in which a strobo unit is used. In the first position, the casing of the strobo unit forms a single rectangular assembly together with the camera and the mounting baseplate to provide a compact construction for convenience in the portable use.
