1. A recording device, comprising:
a recording head that performs recording on a medium mounted on a carriage;
an ejection roller that ejects the medium on which the recording is performed;
a medium receiving tray that receives the medium ejected by the ejection roller, the medium receiving tray taking a first state and a second state displaced from the first state in an ejection direction of the medium;
a motor that is a power source of the ejection roller;
a power transmission section that takes a power transmission state in which power of the motor is transmitted to the medium receiving tray and a power non-transmission state in which the power of the motor is not transmitted to the medium receiving tray, the power transmission section including a friction gear as a power transmission path member;
a switching lever section that switches the power transmission section between the power non-transmission state and the power transmission state by movement of the carriage; and
a holding portion that holds a position of the switching lever section, wherein
the switching lever section has a pin projecting toward the holding portion,
the holding portion has a cam portion, and
when the pin moves at the cam portion in one direction, the power transmission switching section switches between the power non-transmission state and the power transmission state.
 
9. A recording device, comprising:
a recording head that performs recording on a medium mounted on a carriage reciprocating between a first direction and a second direction opposite to the first direction;
an ejection roller that ejects the medium on which the recording is performed;
a medium receiving tray that receives the medium ejected by the ejection roller, the medium receiving tray taking a first state and a second state displaced from the first state in an ejection direction of the medium;
a motor that is a power source of the ejection roller;
a power transmission section that takes a power transmission state in which power of the motor is transmitted to the medium receiving tray and a power non-transmission state in which the power of the motor is not transmitted to the medium receiving tray, the power transmission section including a friction gear as a power transmission path member;
a switching lever section that switches the power transmission section between the power non-transmission state and the power transmission state by movement of the carriage; and
a holding portion that holds a position of the switching lever section, wherein
the carriage moves in the first direction when the switching lever section switches from the power non-transmission state to the power transmission state and when the switching lever section switches from the power transmission state to the power non-transmission state,
the switching lever section has a pin projecting toward the holding portion,
the holding portion has a cam portion, and
when the pin moves at the cam portion in one direction, the power transmission switching section switches between the power non-transmission state and the power transmission state.
 
14. A recording device, comprising:
a recording head that performs recording on a medium mounted on a carriage reciprocating between a first direction and a second direction opposite to the first direction;
an ejection roller that ejects the medium on which the recording is performed;
a medium receiving tray that receives the medium ejected by the ejection roller, the medium receiving tray taking a first state and a second state displaced from the first state in an ejection direction of the medium;
a motor that is a power source of the ejection roller;
a power transmission section that takes a power transmission state in which power of the motor is transmitted to the medium receiving tray and a power non-transmission state in which the power of the motor is not transmitted to the medium receiving tray, the power transmission section including a friction gear as a power transmission path member;
a switching lever section that switches the power transmission section between the power non-transmission state and the power transmission state by movement of the carriage;
a holding portion that holds a position of the switching lever section; and
a rotation stopping section that moves, in the power non-transmission state, to a position where a rotation of the friction gear is stopped and is separated, in the power transmission state, from the position where the rotation of the friction gear is stopped, wherein
the rotation stopping section meshes with the friction gear in the power non-transmission state,
the switching lever section has a pin projecting toward the holding portion,
the holding portion has a cam portion, and
when the pin moves at the cam portion in one direction, the power transmission switching section switches between the power non-transmission state and the power transmission state.
