  • Publication number: 20250135784
    Abstract: An inkjet printer that can reduce abrasion of an absorber and a wiper with removal of wiper ink as much as possible, and can prevent adverse effects caused by abrasion powder thereof is provided. When a wiper at a standby position is lifted, an upper surface of the wiper is brought into contact with an absorber above the standby position, and wiper ink adhering to the upper surface of the wiper is absorbed by the absorber and removed. At this time, the wiper and the absorber are not rubbed against each other. Thus, abrasion of the wiper and the absorber can be reduced as much as possible.

  • Publication number: 20240402215
    Abstract: A scanning probe microscope according to one aspect of the present disclosure divides an observation target region of a sample into a plurality of regions, and drives a scanner to scan the surface of the sample for each region. The data processing unit acquires image data corresponding to the respective regions in the plurality of regions. The input means accepts a user input regarding the acquisition conditions for the plurality of pieces of image data. The acquisition conditions include scanning conditions of the scanner. When the input means accepts a user input for any two variables out of three variables consisting of a scanning range of the scanner for each image data, a spacing between two adjacent scanning ranges, and a maximum number of fields of view capable of being obtained from a maximum scanning range of the scanner, the data processing unit is configured to calculate a remaining one of the three variables based on the accepted two variables.
