A display unit (22) is positioned on the back side of the operation key (24), and a display-information image displayed on the image display unit (22) passes through the image transmissive part (26) and becomes visible on the front surface of the operation key (24). An inclined surface is formed on at least a portion of a rear surface (26a) of the image transmissive part (26) provided to the operation key (24). In a direction parallel to the front surface of the image transmissive part (26), the inclined surface is caused to be inclined towards the front surface side of the image transmissive part (26) from the end near an operator towards the far side, when the image transmissive part (26) is viewed from an angle.</p> |
