Control unit 1101 and determination unit 1102.
Light source colour measuring device P1、P2、P3、···、PNIt is connect with interface 1100.
Control unit 1101 is to light source colour measuring device P1、P2、P3、···、PNIt is controlled.
The ratio of the capacity of the electric power according to needed for one motor 1041 of driving of determination unit 1102 and power supply 1081, determines
The quantity for the motor 1041 that can be driven simultaneously.In the 1st embodiment, the motor 1041 that is judged to driving simultaneously
Quantity be one.
Power supply 1081 is AC adapter, battery etc., is supplied electric power to main body 1080, and the Xiang Guangyuan face via main body 1080
Color measuring device P1、P2、P3、···、PNIt supplies electric power.Therefore, main body 1080 is driven by power supply 1081, and to light source colour
Measuring device P1、P2、P3、···、PNIt supplies electric power.
Communication between 1.6 control devices and light source colour measuring device
In the case where the mode of light source colour measuring device P is usual measurement pattern, control unit 1101 is to light source colour
Measuring device P sends the measuring command for usually measuring.Light source colour measuring device P receives transmitted from control unit 1101
Measuring command for usually measuring executes light source colour measurement in response to the reception for the measuring command usually measured,
And control unit 1101 is sent by the data for indicating the measured value of light source colour measurement.
In the case where the mode of light source colour measuring device P is correction mode, control unit 1101 is measured to light source colour
