    • A portable blower includes a casing (2) having an intake port (6) and a discharge port (7); an air passage (8) provided inside the casing (2) and connecting between the intake port (6) and the discharge port (7); a blower fan (17) arranged inside the air passage (8); a filter (16) arranged at the intake port (6); and a lid portion (3) openably fitted to the casing (2), the lid portion (3), when open, exposing the intake port (6) and, when closed, covering the intake port (6). When open, the lid portion (3) supports the casing (2) to let it stand on a table top. As the blower fan (17) is operated, outside air is introduced through the intake port (6) into the air passage (8) so as to be sent out through the discharge port (7).

    • Object To provide a highly accurate and stable pulse width modulation (PWM) pulse signal generation device compatible with high resolution images without increasing a basic frequency of an external oscillation circuit.Solving Means A PWM pulse signal generation device includes a first PLL control circuit 410, a ring oscillator 420 in which a plurality of basic delay elements are serially connected, and a delayed pulse generation circuit constituted by a delay ratio adjusting circuit 330 and a delay circuit 350. The delay circuit 350 is formed by setting one adjustment delay element having a delay ratio R that is adjusted by the delay ratio adjusting circuit 330 at a first stage and a plurality of serially connecting basic delay elements. An output pulse signal from each delay element of the ring oscillator 420 and an output pulse signal from each delay element of the delay circuit 350 having a delay amount corresponding to the delay ratio are superimposed to perform pulse width modulation, whereby output pulses having various pulse widths can be generated.

    • A plurality of photosensors are provided as light measuring elements at respectively different positions within a space between an optical unit and an image sensor so as to be outside the optical path of the direct light from a photographic subject entering through an optical unit. The plurality of photosensors detect the brightness of the image sensing surface of the image sensor during photoelectric conversion by the image sensor. For this reason a light adjusting controller is capable of performing light adjusting control simultaneously with a main photography operation by controlling the flash emission based on the amount of light detected by the plurality of photosensors during image sensing.
    • 在光学单元和图像传感器之间的空间内的不同位置处设置多个光电传感器作为光测量元件,以便在来自通过光学单元进入的被摄体的直射光的光路外。 多个光电传感器通过图像传感器在光电转换期间检测图像传感器的图像感测表面的亮度。 为此,光调节控制器能够通过基于在图像感测期间由多个光电传感器检测到的光量来控制闪光发射,同时进行主拍摄操作的调光控制。
