Abstract: An accumulated wear amount calculation section calculates a wear amount of a blade edge of a punch and a wear amount of a blade edge of a die when a tool set of the punch and the die has processed a sheet metal once. The accumulated wear amount calculation section calculates an accumulated wear amount of the blade edge of the punch and an accumulated wear amount of the blade edge of the die by accumulating wear amounts of respective times when the tool set has processed the sheet metal multiple times. A tool management information managing section manages a state of the blade edge of each punch and each die by causing a tool management information storage section to store tool management information associating a tool identification code given to each punch and each die with the accumulated wear amounts calculated by the accumulated wear amount calculation section.

Abstract: A portable information device includes: a chassis; a decorative plate fixed to a part of an outer face of the chassis with stretch releasable double-sided adhesive tape; and a cover member that covers the outer face and the decorative plate. The double-sided adhesive tape has: an adhesive portion including adhesive layers on first and second faces of a substrate for adhesively fixing between the decorative plate and the outer face; and a tab including release paper partially covering the adhesive layers to let a user hold the tab for stretch release of the adhesive portion from between the decorative plate and the outer face. The double-sided adhesive tape has a first groove and a second groove on the first face and the second face, respectively, that are positioned not to overlap in a thickness direction of the substrate.

Abstract: The electronic apparatus has: a flat-shaped main body chassis provided with a motherboard; a switch provided at an end portion of the motherboard; a button for pressing an actuator of the switch; a restriction section that restricts the button from rotating around a contact portion when the button presses the actuator; and a button opening formed in a side wall of the main body chassis at a position shifted to a higher level than the switch. The button includes: an operation section exposed through the button opening; an arm portion that extends to a position facing the actuator; and a fin piece that protrudes. The restriction section is provided in such a manner as to face the fin piece at a position vertically shifted to a lower level then the fin piece.

Abstract: A fixing device to fix a toner image formed on a recording medium to the recording medium includes a rotating member, a guide member, a holding member, and a roller. The roller contacts with an outer surface of the rotating member and forms a fixing nip portion together with the guide member between the rotating member and the roller. The fixing device fixes the recording medium toner image to the recording medium while pinching and conveying the recording medium in the fixing nip portion. The guide member is pivotable relative to the holding member about a pivot point that is a shaft substantially perpendicular to a surface of the fixing nip portion. When the rotating member slides on the guide member, the guide member pivots due to a force received from the rotating member so that alignment of the guide member with respect to the holding member is corrected.
