Abstract
Abstract An electronic wristwatch with a printer has a printing head which is arranged inside a wristwatch case with a recording paper loading portion and which performs printing on the recording paper. The printing head is moved by an operation member, and a displacement thereof is detected by a detecting portion. A print control circuit controls printing of the printing head in accordance with a speed corresponding to the displacement detected by the detecting portion.
