1. An input/output device for receiving light reception results of a sensor and outputting the light reception results to an external device, the sensor including a plurality of light receivers to receive light emitted from a plurality of light emitters, the input/output device having a smaller maximum volume of data transmittable per unit time in communicating with the external device than in communicating with the sensor,
the input/output device comprising:
an obtainer configured to obtain the light reception results;
an analyzer configured to analyze the light reception results and repeatedly calculate a number of the light receivers, among the plurality of light receivers, that have received no light in any cycle period while an object passes between the plurality of light emitters and the plurality of light receivers; and
an output unit configured to output data indicating the number of the light receivers calculated by the analyzer to the external device.
