Abstract: A pen holding device configured to hold an electronic pen which has a first core that is elongated and is replaceable. The pen holding device includes a casing having an electronic pen holder that is configured to hold the electronic pen in an erect state or a laid state, and at least one refill core holder which is provided inside the casing and is configured to grasp a second core, which is a refill core for the electronic pen, in a direction different from a longitudinal direction of the electronic pen when the electronic pen is held in the erect state.

Abstract: A hand-written information processing apparatus is provided by which such correction as to directly deal with a design drawn on a paper sheet or the like can be performed. The hand-written information processing apparatus includes a stylus detection sensor, a connection interface for outputting writing information corresponding to a writing operation of a stylus to an external apparatus which includes a display screen for displaying an image, and a display image processing information generation circuit for generating display image processing information for performing a given image operation process based on an operation input accepted by an operation input acceptance unit to the display image. An inputting face is configured such that a sheet member on which writing corresponding to a writing operation of a stylus can be visually formed can be placed thereon. In addition to a normal stylus, an ink stylus which can form a writing trace visually on a sheet member can be utilized.
