Liquid discharging apparatus
A liquid discharging apparatus includes a head that discharges a liquid onto a medium, a medium supporting portion that supports the medium, a heater that heats the medium supported by the medium supporting portion, and a detecting unit that performs sensing and detects energy. The radiation energy of the heater is controlled on the basis of the energy detected by the detecting unit. The medium supporting portion is provided with a sensing target portion that can be sensed by the detecting unit.
1. A liquid discharging apparatus comprising:
a head that discharges a liquid onto a medium;
a medium supporting portion that supports the medium;
a heater that heats the medium supported by the medium supporting portion;
a detecting unit that performs sensing and detects energy; and
a control unit that controls radiation energy of the heater based on the energy detected by the detecting unit,
wherein a size of a sensing area that the detecting unit senses is controlled by the control unit to be variable based upon whether the medium is sensed or not by the detecting unit, such that when the medium is not sensed by the detecting unit, the control unit causes the detecting unit to reduce the size of the sensing area sensed by the detecting unit and when the medium is sensed by the detecting unit, the control unit causes the detecting unit to increase the size of the sensing area sensed by the detecting unit.
2. The liquid discharging apparatus according to claim 1 ,
wherein the detecting unit senses a sensing target portion or the medium supported by the medium supporting portion.
3. The liquid discharging apparatus according to claim 2 ,
wherein a size of the sensing area changes between when the detecting unit senses the sensing target portion and when the detecting unit senses the medium supported by the medium supporting portion.
4. A liquid discharging apparatus comprising:
a head that discharges a liquid onto a medium;
a heater that heats the medium;
a detecting unit that performs sensing and detects energy;
a sensing target portion that is sensed by the detecting unit;
a medium supporting portion that supports the medium; and
