Abstract
A print head is supported on an upper frame of a printing device and a platen and a feeding device are supported on a lower frame. Further, a circuit substrate, a print head moving motor, and a feeding device driving motor are also supported on the upper frame. The upper and the lower frame are connected by a connection member around a rotating axis which is substantially orthogonal to the feeding direction of the print medium. The rotating axis is near a side of the platen in order to easily open and shut the upper frame. When a lock arm is released, the upper frame is pushed up by only a small angle through operation of a pre-open lever and is held in a pre-open position. When upper frame is further opened in an opening direction, the upper frame is held in a fully open position by the operation of an open lock lever. When in the fully open state, the exchange of print paper and/or the removal of the jammed paper can be done easily and safely.
