Abstract: A reading unit is configured to capture an image of a shadow generated at a leading end of a document, and a control unit is configured to estimate a thickness of the document based on a pixel value of the shadow. A multifeeding error is displayed on a display unit when it is determined as thin paper in a thick paper determination. The control unit turns multifeeding detection to OFF and stands by until a feeding is completed, and upon completion, returns the multifeeding detection to ON.

Abstract: A theoretical threshold corresponding to a transport path is set, and a control unit acquires a calculation value calculated based on a detection result of double feeding detection unit and a transport length of a document, determines occurrence of double feeding when the calculation value is greater than the theoretical threshold (step S120), and determines non-occurrence of double feeding when the calculation value is smaller than the theoretical threshold. In addition, if a non-detection period for double feeding occurs (step S110), the control unit sets a cumulative value in step S115. As a result, detection of double feeding is ended in a short period while a document is being transported, and in a case that double feeding is no longer detected, determination of double feeding will not be made.

Abstract: A drilling jig for drilling a punching hole with a boundary between a basis material and a coating of a workpiece less noticeable, and a drilling method using this drilling jig. It includes a male blade, a female blade, and a hexagon bolt; the male blade and the hexagon bolt are capable of being coupled to each other; a screw hole, through which the hexagon bolt is inserted, and a blade portion are formed in the male blade; the blade portion has a planar blade surface; a shaft insertion hole, through which the hexagon bolt is inserted, and a blade portion housing hole capable of housing the blade portion are formed in the female blade, whereby the boundary between the basis material and the coating of a bumper can be positioned on the inside of the punching hole, preventing the appearance of the punching hole from being impaired.

Abstract: An image reading device includes a reading unit that reads a document sheet and a reading standard surface and outputs read values corresponding to pixels arranged in a main scan direction, a control unit that processes the read values, and a storage unit storing information to be referenced by the control unit. In the storage unit, first data that is read values of the reading standard surface and serves as standards, and second data on ranges of variation, based on a change in a temperature, in the read values are stored. The control unit determines, based on the first data and the second data read from the storage unit and third data obtained by reading the reading standard surface after an acquisition of the first data, whether an abnormality exists in the pixels.

Abstract: Provided is a highly versatile attachment component corresponding to a space around an attachment location of a vehicular member. A retainer for attaching an ultrasonic sensor to a vehicle has a member holding portion for holding the ultrasonic sensor; and an attachment portion that is to be attached to the vehicle. The attachment portion has a center attachment part; a plurality of attachment pieces which are an upper attachment piece, a lower attachment piece, a left attachment piece and a right attachment piece; and cuttable sections joining the center attachment part and the multiple attachment pieces. These attachment pieces can be removed by cutting the cuttable sections. Therefore, some of the attachment pieces may be removed so as to secure a space around a location to which the ultrasonic sensor is to be attached, thus allowing the ultrasonic sensor to be attached to the vehicle.

Abstract: A structure securely attaches a component to an opening portion in a plate-shaped member without stripping or turning over the member. Each of a pair of mount members includes a first engagement portion engaged with a rear surface of the plate-shaped member and a second engagement portion engaged with the component. The component includes projecting portions to be fitted between the mount members, thus the component can be fixed against coming off by engagement of the second engagement portion and the component. The projecting portions inhibit the mount members engaged with the opening portion from moving, thereby preventing the mount members from coming off the opening portion. Since the fitting member is fitted between the second engagement portions, the fitting member inhibits the second engagement portions from moving to come closer to each other, and from disengagement from the component, thereby more securely preventing the component from coming off.

Abstract: In a structure, which securely attaches a component to an opening portion in a plate-shaped member without stripping or turning over the plate-shaped member, each of a pair of mount members includes a first engagement portion engaged with a rear surface side of the plate-shaped member and a second engagement portion engaged with the component. The component includes projecting portions to be fitted between the mount members to enable fixing against coming off by engagement of the second engagement portion and the component. The projecting portions inhibit the mount members from moving so as not to come off the opening portion. Since the second engagement portion is formed from the multiple step portions engageable with the component, engagement with the component may be done even if plate thickness of the plate-shaped member varies, enabling fixing without backlash and improving versatility to the plate-shaped member having different plate thickness.
