1. A standing-up assist device comprising:
a base portion;
a shaft portion, having one end connected to the base portion, capable of moving at least up and down;
a support portion provided at another end of the shaft portion;
a control unit for controlling movement of the shaft portion; and
a user information input unit to which information of a user is input, the information of the user including at least any of physical information and health information of the user, and the health information of the user includes information on a state of a predetermined part in a body of the user,
wherein,
a speed at which the support portion moves when the user is standing up is defined as a first moving speed, the control unit changes the first moving speed according to at least any of the physical information and the health information of the user,
the shaft portion includes a first shaft member and second shaft member that is at a front direction, of the user using the standing-up assist device and in a front-rear direction of the standing-up assist device, relative to the first shaft member, the first shaft member and the second shaft member each being expandable,
a lower end portion of each of the first shaft member and the second shaft member is provided with a turning shaft for turning in the front-rear direction,
the control unit changes a trajectory of the support portion in standing up, according to information on the state of the predetermined part in the body of the user, the trajectory being formed when the support portion is moved by expansion and contraction of the first shaft member and the second shaft member, and turning at the turning shaft of each of the first shaft member and the second shaft member, and
when an input for the health information on the state of the predetermined part in the body of the user indicates that there is a pain in a knee region as the predetermined part in the body of the user, the control unit increases the contraction of the second shaft member against a predetermined normal trajectory in standing up.
