Abstract

Claims (31)

1 . An electronic device including a first unit and a second unit that are detachably attached to each other, the electronic device comprising:

a first connector that is provided in the first unit;

a socket that is provided in the second unit, the first unit being attached to and detached from the socket in a first direction;

a lock mechanism that fixes the first unit to the socket;

a second connector that is provided in the socket, the second connector coming into contact with the first connector in the first direction to be electrically connected;

a connector holder that is provided in the socket to be shiftable in the first direction, the connector holder maintaining the second connector;

a connector holder shift mechanism that shifts the connector holder in the first direction;

a link mechanism that mechanically links the lock mechanism and the connector holder shift mechanism, the second connector coming into contact with the first connector when the fixing of the first unit to the socket is completed, and the second connector being separated from the first connector when the fixing of the first unit to the socket is released; and

an elastic member that biases the second connector in a direction from the second connector to the first connector,

wherein

the link mechanism includes:

a slide member that slides in a second direction orthogonal to the first direction, and

a knob that is provided in the slide member,

the connector holder shift mechanism includes:

a cam follower roller that is provided in the slide member, and

a cam groove that is disposed in the connector holder to engage with the cam follower roller, and

the cam groove shifts the connector holder in the first direction by the sliding of the slide member in the second direction via the cam follower roller;

wherein

the lock mechanism includes a lock shaft that rotates about a rotation center line extending in the first direction and is shifted in the first direction by sliding of the slide member of the link mechanism,

the lock shaft includes a hook part having a non-circular shape as viewed in the first direction, and

the first unit includes an annular member having an annular shape that includes a through-hole having a non-circular shape as viewed in the first direction, the hook part being configured to pass through the through-hole, and the hook part of the lock shaft in a state of being rotated at a predetermined rotation angle being caught on the annular member.

2 . The electronic device according to claim 1 , wherein the lock mechanism includes

a first rotating member holding the lock shaft, being rotatable about the rotation center line, and including a crank part connected to the slide member,

a second rotating member having an annular shape, being rotatable about the rotation center line, including a cam follower on an inner peripheral surface, and including a crank part coupled to the slide member, and

a cam member having a cylindrical shape, being movable in the first direction, including a cam groove extending in the first direction while extending in a circumferential direction on an outer peripheral surface and engaging with the cam follower, and shifting the lock shaft in the first direction.

3 . The electronic device according to claim 1 , wherein

the second connector is provided in the connector holder to be movable in the first direction, and

the elastic member is provided in the connector holder.

4 . The electronic device according to claim 1 , wherein

the first unit is a tablet terminal including a touch screen, and

the second unit is a keyboard unit including a keyboard.
