An acceleration detection device is provided with a zero point correction unit for correcting a zero point position of a sensor signal value by using the correction amount based on the acceleration when the vehicle transitions from a stopped state on a sloping road to a running state. The number of pixels necessary to create embroidery data is determined from thread density, size of the embroidery, and copied color data. Light is received from the solar light collector and supplied as a backlight to the electronic transmissive display panel. The notched surface is circumferentially adjacent to the attachment hole and is substantially orthogonal to the attachment hole. A perimeter of the insertable device is sized to be sealable inserted into the universal access port.
