Abstract
An arrow is provided with a light emitting function, a nock with a light emitting function, and a light emission control device to be used in an arrow which thereby realize accurate and stable light emission periods of time and a reduction in size and weight of light emitting members by using an electronic circuit with an acceleration sensor switch in its light emission control part. The control device includes an acceleration switch, a capacitor circuit including a capacitor and a resistor, and an electrical circuit installed inside the arrow, nock, or attachable to and detachable from the arrow. Electricity is applied when the arrow is discharged from a bow to emit light for a set period of time.
