Abstract
Disclosed is a recording apparatus including a recording head that performs recording with respect to a medium at a prescribed distance, a contact section that is capable of being in contact with the medium, a carriage that changes a relative location between the medium and the contact section, and an ultrasonic sensor that is capable of sensing an ultrasonic wave which is generated in a case where the medium is in contact with the contact section. The carriage changes the relative location such that a relative velocity between the medium and the contact section is over a prescribed value (transport velocity of the medium), and the ultrasonic sensor is capable of detecting a state of the medium by sensing the ultrasonic wave.

A detection device that is capable of detecting a state of a medium, the device comprising:
- a contact section that is capable of being in contact with the medium;
- a location change section that changes a relative location between the medium and the contact section;
- and
- an ultrasonic sound wave sensing section that is capable of sensing an ultrasonic sound wave which is generated in a case where the medium is in contact with the contact section,
- wherein the location change section changes the relative location such that a relative velocity between the medium and the contact section is equal to or larger than a prescribed value, the location change section comprising a carriage configured to move the contact section in a direction different from a transport direction of the medium, and
- wherein the ultrasonic sound wave sensing section is capable of detecting the state of the medium by sensing the ultrasonic sound wave.
A recording apparatus comprising:
- a recording section that performs recording on a medium at a prescribed distance;
- a contact section that is capable of being in contact with the medium;
- a location change section that changes a relative location between the medium and the contact section;
- and
- an ultrasonic sound wave sensing section that is capable of sensing an ultrasonic sound wave which is generated in a case where the medium is in contact with the contact section,
- wherein the location change section changes the relative location such that a relative velocity between the medium and the contact section is equal to or larger than a prescribed value, the location change section comprising a carriage configured to move the contact section in a direction different from a transport direction of the medium, and
- wherein the ultrasonic sound wave sensing section is capable of detecting the state of the medium by sensing the ultrasonic sound wave.
A recording apparatus comprising:
- a recording section that performs recording on a medium at a prescribed distance;
- a contact section that is capable of being in contact with the medium;
- a transport section that transports the medium in a transport direction;
- a location change section that changes a relative location between the medium and the contact section;
- and
- an ultrasonic wave sensing section that is capable of sensing an ultrasonic wave which is generated in a case where the medium is in contact with the contact section,
- wherein the location change section changes the relative location such that a relative velocity between the medium and the contact section is equal to or larger than the transport velocity of the medium,
- wherein the ultrasonic wave sensing section is capable of detecting the state of the medium by sensing the ultrasonic wave,
- wherein the location change section includes the recording section and the contact section which are mounted thereon, and is capable of moving to face the medium in a direction which crosses the transport direction.
