1. An image processing device comprising:
a light receiving element;
a light emitting element;
a battery;
a power source circuit electrically coupled to the battery;
a first substrate provided with the light receiving element;
a second substrate provided with the light emitting element;
a third substrate provided with the power source circuit;
a fourth substrate; and
a casing storing the first substrate, the second substrate, the third substrate, and the fourth substrate, wherein
the battery is located between the first substrate, the second substrate, and the third substrate, and the fourth substrate,
a first portion of the battery facing the first substrate, the second substrate, and the third substrate has a smaller sectional area as the first portion comes closer to the first substrate, the second substrate, and the third substrate, and
a second portion of the battery facing the fourth substrate has a smaller sectional area as the second portion comes closer to the fourth substrate.
