DEVICE FOR IMAGE FORMATION AND BLOCK OF ISSUE DETECTION Russian patent published in 2017 - IPC B41J2/01 

FIELD: physics.

SUBSTANCE: block of detecting emission for detecting, whether a droplet is provided or not, includes a droplet dropping link having a droplet surface, on which the droplet falls, a wiper link configured to erase a droplet from the droplet dropping surface, onto which the droplet falls, and also a cleaning link configured to erase a droplet adhered to the wiper link, from the wiper link for cleaning. The wiper link is configured to be elastically deformed when pressed to the cleaning link. The cleaning link includes a contact part, with which the wiper link contacts after the droplet is erased from the droplet dropping surface. The contact portion of the cleaning link is in a form to make contact with the wiper link on the first lateral ends of the cleaning link and then gradually to the center of the cleaning link in the direction perpendicular to the direction of wiping carried out by the wiper link.

EFFECT: reducing the accumulation of liquid waste on the cleaning link and preventing a decrease in the quality of wiping carried out by the wiper link.
