Abstract: PURPOSE:To attain optimum white balance control under fluorescent light lighting by providing a means detecting a color temperature of a lighting, integrating its output, converting it into a pulse signal for a prescribed period, discriminating whether the light is an incandescent light or a fluorescent light and controlling the light. CONSTITUTION:An integration device 2 receives an input voltage Vin from a color temperature sensor 1 and the input of the integration device 2 connects to ground by using pulses, 8 for first half period and 8 for latter half period with a prescribed pulse width through a switch S1. In the case of an incandescent light, the voltage Vin is constant and the pulse width at a Vout, a CPU 3 compares maximum and minimum values of the width of 16 pulses and there is no difference, which is the bases of the discrimination of the incandescent light. In the case of a fluorescent light, the voltage Vin is fluctuated and the pulse width of the voltage Vout has a dispersion and the CPU 3 discriminates a difference of a prescribed value or over between the maximum values and the minimum values, which is the bases of the discrimination of the fluorescent light.

When the platen is rotated forward by a predetermined amount, the pawl 6a is dropped into the groove 11'' in the zone II by a turning part 10a depending on the amount, but since the distance from the turning part 10a to the pawl hole 11' is set to be larger than the length corresponding to the allowable reverse rotation quantity of the platen, even when the platen is reversely rotated a predetermined allowable reverse rotation quantity during printing, the pawl 6a does not engage with the hole 11', and the clutch is not engaged.
