Abstract: Provided is an electronic pen including a rod-like member that includes a pen tip at a front and is supported movably in a longitudinal direction, an electronic component, at least a portion of which is provided on a rear side of the rod-like member opposite to a side on which the pen tip is included, a casing that has a tubular shape and stores the rod-like member and the electronic component, and a transmission member that is provided in a space interposed between the electronic component and an inner circumferential surface of the casing and transmits an externally received force at a rear of the rod-like member to move the rod-like member in the longitudinal direction.

Abstract: A pixel interpolating device includes a cycle calculation unit and an interpolating unit. The cycle calculation unit calculates a cycle in change of pixel values of pixels in a document image obtained by reading a document by first and second photoelectric conversion element arrays each having a plurality of photoelectric conversion elements. The interpolating unit extracts from the pixels such pixels that an interval between each pixel and an interpolated pixel corresponding to a position between the first and second photoelectric conversion element arrays corresponds to the cycle calculated by the cycle calculation unit. The interpolating unit interpolates a pixel value of the interpolated pixel based on pixel values of the extracted pixels.
