Abstract:
1. A cap moving mechanism for moving a cap for sealing a liquid ejecting head for ejecting liquid to a target, comprising: a pushing-up part for moving said cap upwards or downwards by rotating; a cam shaft provided integrally with said pushing-up part as a rotating shaft of said pushing-up part; a cam shaft gear comprising a drive region, which rotates integrally with said cam shaft taken as a rotating shaft, whereby a driving force of a motor for driving said cam shaft is transmitted, and a non-drive region whereby said driving force of said motor is not transmitted; and a driving force transmission gear for transmitting said driving force of said motor to said cam shaft gear in order that said cap can be moved downwards from a state in which said cap has been completely moved upwards, after said motor rotates by a predetermined amount from when said cap has been completely moved upwards, and transmitting said driving force of said motor to said cam shaft gear in order that said cap can be moved upwards from a state in which said cap has been completely moved downwards, after said motor rotates by a predetermined amount from when said cap has been completely moved downwards; wherein said driving force transmission gear comprises: wherein said toothed gear is arranged between said cam shaft gear and said spur gear.
