Abstract
In a stride measuring apparatus, a signal wave emitter and a signal wave detector are opposed to each other in a direction intersecting with a predetermined direction in which the running surface is driven. The signal wave emitter emits a light beam. The signal wave detector outputs an ON signal when receiving the light beam, and outputs an OFF signal when the light beam is intercepted. A detector part calculates a moving speed on the basis of a difference between a fall time and a rise time of one OFF signal out of two OFF signals outputted in succession from the signal wave detector, and a foot size of a subject. The detector part calculates a difference between output times of the two OFF signals (stride time) and calculates a stride on the basis of a product of the moving speed and the stride time.
