Abstract
Provided is a reverse connection preventing structure in a battery-driven object detection device, which has a simple structure capable of preventing reverse connection of even a battery whose projecting positive electrode is relatively lower in height. The structure has a holder for holding the battery including a first terminal for electrically connecting to a projecting positive electrode and a second terminal for electrically connecting to a negative electrode. The first terminal is formed in a printed circuit board. On the printed circuit board, an insulating member of less than 0.5 mm in thickness are provided around the circumference of the first terminal in such a manner as to allow the first terminal to come in contact with the positive electrode of the battery which is mounted correctly and as to prevent the first terminal from coming in contact with the negative electrode of the battery which is mounted reversely.
