Document Type and Number:
Japanese Patent JP2019154523
Kind Code:
A
Abstract:
To provide a biological information measuring device capable of causing a specific light emitting device to emit a light with a high frequency as compared with a case where a plurality of kinds of control signals are output continuously during a non-light emission period of the specific light emitting device.SOLUTION: A biological information measuring device 10A includes; a light emitting device LD1 for irradiating a light of a first wavelength; a control unit 12 for outputting a control signal for controlling light emission of the light emitting device LD1 so as to repeat a light emitting period and a non-light emitting period, and controlling an output period of a plurality of kinds of control signals so that the plurality of kinds of control signals output in mutually different periods in the non-light emitting period are output in such a manner that the respective periods do not continue and the light emitting period is interposed therebetween; and a measuring unit 20 for measuring biological information on a living body using: light that is irradiated from the light emitting device LD1 to the living body, and that transmits the living body or is reflected by the living body; and the control signal of the plurality of kinds of control signals.SELECTED DRAWING: Figure 11
