A strobe device is provided with a light-emitting unit rotatably coupled to a strobe body unit detachable from a bracket together with an imaging apparatus, a variable mechanism configured to allow a change in an angle of orientation of the light-emitting unit with respect to the strobe body unit, a driving unit configured to drive the variable mechanism, and a control section configured to control the driving unit. The control section has a control mode to restrain the light-emitting unit from moving to a region in which the imaging apparatus is located when it is detected that the strobe body unit is attached to the bracket. As a result, the strobe device whose the light-emitting unit does not bump against the imaging apparatus can be realized.

Strobe device and imaging device provided with strobe device

A flash device of the present invention includes a flash main body, a light emitting section rotatably coupled to the flash main body, and a variable mechanism that can vary the angle in the vertical direction of the light emitting section between a normal irradiation direction angle and a desired irradiation direction angle different from the normal irradiation direction angle. The flash device further includes a drive section for driving the variable mechanism, a vertical direction angle detecting section for detecting the angle in the vertical direction of the light emitting section, and a control device for changing, with the drive section, the angle in the vertical direction of the light emitting section to the desired irradiation direction angle based on a detection signal of the vertical direction angle detecting section. Thus, the angle can be instantly changed to the desired irradiation direction angle, the time taken for preparation for photographing can be reduced, and a subject can be bounce-photographed without missing the photo opportunity.

Flash device and image capture device provided with flash device

The electronic flash unit disclosed comprises: a transformer () to vary voltages of a power supply; an accumulator () composed of a main capacitor () to charge an electric energy supplied from the transformer (); a lamp unit () provided with a flashlamp (), set inside of a reflector (), that flashes by discharging of energy storages in the main capacitor () upon applying a voltage on a trigger terminal (); and a trigger circuit () to generate the voltage to apply on the trigger terminal (), wherein at least the lamp unit () is coated with an insulation material.

Electronic flash unit and manufacturing method thereof

In order to vary a light emission angle, a light source is moved so that its position relative to a reflector is varied. In one mode, by compulsively moving the light source to one end of a movement range of the light source, the one end is set as an original position. In another mode, after the light source is compulsively moved to the one end, by detecting that the light source has reached a position preset in the movement range while the light source is being moved to the other end of the movement range, a distance by which the light source is moved from the one end to the preset position is detected and stored as control information. The subsequent operation to move the light source to a desired control position is controlled based on the original position which is the one end or based on the control information.
