I have no voice, but I speak of old, Carved in stone or cast in mold. I can hold a web page, a pill, or a law, What am I?

I can be twisted, I can be turned,To open a door or change what is heard.I have no eyes, but I am a head,Found on a drawer or next to your bed.What am I?

A tool of math with a royal name Of wood, steel or plastic frame Tiny ticks count up or down Governs space, it earns a crown

You can sit on me, some people might take a nap on me, or if I'm in a courtroom you might approach me, by invitation only of course. What am I?

I am a purpose inside of your head, Take my 'in' outside and you're camping instead.
