A first surface of the first flexible substrate faces a second surface of the second flexible substrate. The first buffer layer, the first crack inhibiting layer, and the input device are provided on the first surface side of the first flexible substrate. The first buffer layer includes a region overlapping with the first crack inhibiting layer. The first buffer layer is between the first crack inhibiting layer and the first surface. The input device includes a transistor and a sensor element. The light-emitting element is provided on the second surface side of the second flexible substrate.

An electronic apparatus includes a main body housing, a design panel to be mounted to a front surface of the main body housing, a button which is configured such that an end extends in cantilever fashion from an end portion fixed to the design panel and in which an operation part provided at the end is exposed to the outside through an opening of the design panel, a drain groove, provided around the operation part, whose an end portion in a direction in which the end is tilted due to pressing of the operation part is open, and a drain groove provided in the front surface of the main body housing on the side of the open end portion of the drain groove and leads to the outside of the main body housing.

A calculation device comprises a display including both a first display area and a second display area, and a processor being configured to accept operations of at least one of a tax calculation key which are associated with a plurality of tax rates, respectively, to display, when the operation of the tax calculation key associated with any one of the plurality of tax rates was accepted with respect to numerical value data which indicates tax-excluded amount data displayed on the first display area, tax-included amount data on the first display area, the tax-included amount data being calculated based on the tax rate corresponding to the tax calculation key; and to display, on the second display area, tax-included total amount data which indicates a total of the tax-included amount data corresponding to at least one of the numerical value data.

A calculator with a handwriting pad includes a handwriting pad unit, a calculator unit, and a handwriting pen. The handwriting pen is detachably arranged on the calculator unit or the handwriting pad unit, and the handwriting pad unit is connected to the calculator unit. When in a storage state, the handwriting pad unit and the calculator unit are arranged in an overlapped manner from up to down. When in an unfolded state, a surface of the handwriting pad unit is horizontally arranged side by side with the calculator unit. The handwriting pad unit, the calculator unit, and the handwriting pen are connected together so that a user can directly access them during use without having to search for them one by one. The handwriting pad unit and the calculator unit can be stacked together when not in use, reducing an overall volume for easy carrying and storage.

A finger-wearable computing device may comprise a processor, a ring base, and a display screen. The display screen is coupled to the ring base and coupled to the processor to display an output. The display screen includes a command area configured to receive user input from a wearer's thumb while the finger-wearable computing device is worn on a wearer's finger. The ring base may be resiliently flexible and may define an overlapping loop with a central opening that expands and contracts to the fit the wearer's finger. The display screen may be flexibly coupled to the ring base and may have a vertical axis that is canted at an angle relative to a central axis of the ring base to ergonomically position the display screen while the wearable computing device is worn on the finger of the wearer's hand.

A wearable computing device can have a processor, a memory, and a display so operatively coupled to the processor and the memory as to display an output therefrom. The processor and the memory can be positioned in a resiliently flexible body. The resiliently flexible body can include a first end and an opposed second end, a first edge and an opposed second edge, wherein the first and the second edges extend between the first end and the opposed second end. The body can also have a wearer-engagement portion positioned between the first end and an intermediate region, wherein the finger-engagement portion of the resiliently flexible body circumferentially so extends around a longitudinally extending axis positioned parallel to the first end and spaced apart from the resiliently flexible body as to define an open interior region, wherein the interior region of the wearer-engagement portion defines an inner surface extending between the first edge and the second edge and between the first end and the intermediate region, wherein the wearer engagement portion further defines an outer surface positioned outward of the interior region and opposite the interior surface. A display portion of the body can be positioned between the intermediate region and the second end, wherein the display is positioned in the display portion on a same side of the resiliently flexible body as the outer surface of the wearer-engagement portion.
