1. An input device comprising:
- a sensor configured to detect an input operation performed on an operation surface;
a front light mechanism disposed on the sensor and configured to illuminate the operation surface;
a mode switching unit configured to select a predetermined operation mode in accordance with the input operation on the operation surface; and
a control unit configured to switch an illuminating operation of the front light mechanism under the control of the mode switching unit,wherein the front light mechanism comprises a light source and a light guide member configured to admit and guide light emitted from the light source therein and to output the light toward the operation surface,wherein the light guide member comprises;
an illuminating surface disposed on one surface and configured to emit the light therefrom; and
an optical region disposed on the other surface opposite the illuminating surface and configured to direct the light toward the illuminating surface,wherein the optical region includes a flat face and a prism face, and one of the flat face and the prism face is shaped like a predetermined mark, andwherein a sheet member is disposed between the light guide member and the sensor, an aperture is disposed in the sheet member at a position opposite to the prism face to form a space at the prism face.

Abstract
A light guide member and a sensor that constitute a front light mechanism are bonded with a bonded sheet. A double-sided adhesive tape is provided on each surface of the bonded sheet. A repairing material is printed on a surface of the sensor so as to fill concave portions provided between the adjacent X-electrodes. This substantially increases the contact area with the double-sided adhesive tape, and increases the bonding strength between the light guide member and the sensor.
