Liquid discharge apparatus

摘要

The liquid discharge apparatus includes a support member supporting a medium while rotating, a head facing the support member and discharging a liquid, a conveyance part conveying a medium between the support member and the head, and a foreign matter detection unit detecting a foreign matter heading toward between the support member and the head in association with the conveyance of the medium. The foreign matter detection unit has a movable roller that faces the support member upstream relative to the head in a conveyance direction of the medium, and nips the medium between the support member and the movable roller, a rotational support member rotatably supporting the movable roller to allow inclination of the movable roller relative to a rotational axis direction, which is a center of rotation of the support member, and a retention member movably retaining the rotational support member in a direction toward the support member.

主权项

1. A liquid discharge apparatus, comprising:
a support member configured to support a medium while rotating; a head facing the support member and configured to discharge a liquid onto the medium supported by the support member; a conveyance part configured to convey the medium between the support member and the head; and a foreign matter detection unit configured to detect a foreign matter heading toward between the support member and the head, in association with a conveyance of the medium by the conveyance part, the foreign matter detection unit having
a movable roller facing the support member on an upstream side of the head in a direction of conveyance of the medium being conveyed by the conveyance part, the movable roller being configured to nip the medium between the support member and the movable roller,a rotational support member rotatably supporting the movable roller so as to allow inclination of the movable roller relative to a rotational axis direction, which is a center of rotation of the support member, anda retention member movably retaining the rotational support member in a direction going toward the support member.
