  • Patent number: 11039027
    Abstract: An image reading apparatus includes a document tray, a set document sensor, a sheet feed rotary member, an image reader, a staple detector, a display panel and a controller. The set document sensor detects a document sheet set on a document tray. A staple detector detects a staple attached to the document sheet bundle. On recognizing set document sheets, based on the output from the staple detector, a controller checks whether or not the set document sheets are stapled. On detecting that they are stapled, the controller makes a display panel indicate that the document sheets are stapled and cannot be conveyed.

  • Publication number: 20210127654
    Abstract: A fishing rod includes a rod section and a fitting having a securing portion, the fitting being firmly secured to the rod section without inhibiting bending of the rod section, the securing portion having an excellent outer appearance. On a securing portion of a fishing line guide placed on the rod section, a prepreg sheet formed of plain-woven reinforcement fibers impregnated with a thermosetting resin is wound to secure the fishing line guide. The prepreg sheet is wound and secured so that, with respect to an axial direction, reinforcement fibers are in oblique directions, and intersecting angles of the reinforcement fibers in a winding region on a part of the rod section located beyond a distal end of the securing portion are smaller than those of the reinforcement fibers in a winding region on the securing portion.

  • Patent number: 10133413
    Abstract: Provided is an input state detection device capable of reliably detecting contact and pressing of an object. A state switching switch can switch a first state in which a voltage application terminal of a constant-voltage power supply is connected to a side of a first electrode and a detection terminal of a detector is connected to a side of second electrodes, and a second state in which the voltage application terminal of the constant-voltage power supply is connected to the side of the second electrodes and the detection terminal of the detector is connected to the side of the first electrode. An input detector detects whether the object is in a non-contact state or in a contact but not pressing state with respect to a surface on the side of the second electrodes based on a value detected by the detector with the state switching switch in the first state.
