摘要： An electronic device includes an open-close detector configured to detect an open-close state indicating whether an optical path open-close device of a film camera is open or closed, a displacement detector configured to detect a displacement of a movable portion of the film camera interlocked with a movement of an operation portion of the film camera, and control circuitry. In response to a detection result of the displacement detector, the control circuitry selects a measurement mode for measuring an open time during which the optical path open-close device is open, from a plurality of operation modes of the electronic device. In the measurement mode, the control circuitry measures the open time based on the open-close state detected by the open-close detector.

摘要： A sheet material conveying device includes: a sheet material housing unit; a sheet material conveying unit that conveys each sheet material to a predetermined conveyance target position; a separating/feeding unit that separates a sheet material from sheet materials in the sheet material housing unit and conveys the separated sheet material alone to the sheet material conveying unit; a multi-feed detecting unit that detects whether multi-feed occurs in which a plurality of sheet materials are fed from the separating/feeding unit to the sheet material conveying unit; and an internal sheet material detecting unit that detects presence of the sheet material in the sheet material conveying unit. The sheet material conveying device performs multi-feed failure detection control for detecting whether a failure occurs in the multi-feed detecting unit before notification of a detection result of the internal sheet material detecting unit.

摘要： A sheet feeding device includes a tray main body and a cover member. The tray main body has a first mount surface. The cover member is rotatably connected to an end of the tray main body on the side opposite to the sheet feeding side so that the cover member can move rotationally between a closed position where the cover member covers the first mount surface and an open position where the first mount surface is exposed, and has a second mount surface on which a sheet is mounted over the first mount surface when cover member is in the open position. The cover member includes an opening for sheet insertion which penetrates through from an upper surface to a bottom surface of the cover member so that a sheet can be inserted onto the first mount surface when the cover member is in the closed position.

摘要： In a diamond cutting saw blade, a plurality of slits 1 are formed at regular intervals on the outer periphery of a disc-shaped iron substrate 2, and a plurality of segment chips 3 are fixed onto the outer periphery of the disc-shaped iron substrate 2. Two trapezoidal concave portions 4 which expand outwardly are formed on both sides of the outer periphery of each segment chip 3. Further, a trapezoidal concave portion 5 is formed at the intermediate position of the segment chip 3 on a joint surface of the iron plate 2 so as to expand toward the joint surface. At the corner where a bottom surface 4a and a tapered surface (side surface) 4b of the concave portion 4 formed on the outer periphery intersect, there is formed a curved surface 4c having a radius of 1.0 to 2.5 mm. Similarly, in a concave portion 5 formed in the inner periphery of the segment chip 3, there is formed a curved surface 5 c having a radius of 1.0 to 2.5 mm at the corner where a bottom surface 5a and a tapered surface (side surface) 5b intersect each other.
