Abstract: A robot includes a first member having a first mounting surface facing upward and a second member having an opening at an upside of the first member and facing the first member and a second mounting surface at the upside, and a joint actuator coupling the first and second members. The joint actuator has a flange fixed to the second mounting surface, a motor placed at the upside with respect to the flange, and a reducer placed at a downside with respect to the flange, projecting downward from the opening, and fixed to the first mounting surface. The joint actuator is mounted on the second mounting surface from the upside and the reducer is projected downward from the opening, and the flange is fastened to the second member from the upside using first screws and the reducer is fastened to the first member from the downside using second screws.

Abstract: A media processing device executes a retard preparation operation that moves a separation roller and a paper return lever at a desired time even when the moving mechanism that moves a separation roller and a paper return lever together, and the conveyance mechanism that conveys the medium, share a common drive source. A printer has a moving mechanism that executes a retard preparation operation that moves the paper return lever and separation roller in conjunction with each other. Drive power from the conveyance motor is transferred to the moving mechanism. The printer also has a trigger lever that can move between an interference position physically interfering with the moving mechanism and preventing the retard preparation operation from starting, and an actuator that moves the trigger lever from the interference position to a non-interference position.
