Liquid ejecting head module and liquid ejecting apparatus
A liquid ejecting head module including: a head unit which has a plurality of heads having a nozzle plate on which a nozzle opening is provided; a carriage to which the liquid ejecting head unit is fixed; and a thermistor attached to the carriage, wherein the thermistor is biased to the cover head side which is in contact with the nozzle plate of a head, comes into contact with the nozzle plate and measures the temperature of the nozzle plate.
1. A liquid ejecting head module comprising:
a liquid ejecting head having a nozzle plate on which a nozzle opening ejecting a liquid is provided;
a fixing member to which the liquid ejecting head is fixed; and
a temperature measurement unit attached to the fixing member,
wherein the temperature measurement unit is biased to a side of the nozzle plate so as to come into contact with the nozzle plate and measures a temperature of the nozzle plate,
wherein the temperature measurement unit includes a ground member which electrically connects the liquid ejecting head and the fixing member, and a temperature sensor provided at the ground member,
wherein the ground member is biased to the side of the nozzle plate and comes into contact with the nozzle plate, and
wherein the temperature sensor measures the temperature of the nozzle plate via the ground member.
2. A liquid ejecting head module comprising:
a liquid ejecting head having a nozzle plate on which a nozzle opening ejecting a liquid is provided;
a fixing member to which the liquid ejecting head is fixed; and
a temperature measurement unit attached to the fixing member,
wherein the temperature measurement unit is biased to a side of the nozzle plate so as to come into contact with the nozzle plate and measures a temperature of the nozzle plate,
wherein the liquid ejecting head has a protection member which comes into contact with the nozzle plate and protects the nozzle plate, and
wherein the temperature measurement unit comes into contact with the protection member and measures the temperature of the nozzle plate via the protection member.
