The 45-year-old, who can not be named for legal reasons, appeared at Lincoln Crown Court on Monday 2nd July.
Standing in the dock, and dressed smartly in a grey suit, he repeated his not guilty plea to all 13 of the allegations put before him.
The offences relate to material found on a laptop and memory stick dated between November 2009 and May 2011.
A total of 415 still and moving images were discovered, and police believe the intention was to distribute them.
Some of the indecent material was classed as level four, with level five being the most serious.
The case was adjourned until 21st January 2013 for a jury trial which is expected to last up to three days.
Judge Sean Morris expressed his dismay at the length of time before a trial would take place, owing to court availability.
“In my view it is a scandal,” he said.
“Some of these trials are not getting on up to a year or a year and a half after the allegation and I am sorry for the defendant.”
The defendant was released on bail with a condition not to have any unsupervised contact with any child under the age of 18.
