## Abstract

An electronic apparatus includes a main body chassis and a keyboard attachable to and detachable from a recessed portion that is recessed downward from a main body upper surface of the main body chassis. A keyboard chassis of the keyboard is provided with a puller mechanism. The puller mechanism includes a rail extending in parallel to the main body upper surface, a slider guided by the rail, and an elastic band provided above the rail, a left end of which is fixed to the slider and a right end of which is fixed to the keyboard chassis. The elastic band is linear and extends along the upper surface in a natural state without an external force, and is elastically curved by the left end being displaced to the right together with the slider along the rail to protrude over the upper surface.

## Claims

### Claim 1

An electronic apparatus comprising:
a main body chassis; and
a keyboard attachable to and detachable from a recessed portion that is recessed downward from a main body upper surface of the main body chassis, wherein
a keyboard chassis of the keyboard includes a puller mechanism having:
a rail extending in parallel to the main body upper surface,
a slider guided by the rail, and
an elastic band above the rail, one end of which is fixed to the slider and an other end of which is fixed to the keyboard chassis, and
the elastic band is linear and extends along the main body upper surface in a natural state without an external force, and is elastically curved by the one end being displaced together with the slider along the rail and thereby protrudes over the main body upper surface.

### Claim 2 (depends on 1)

The electronic apparatus according to claim 1, wherein
the keyboard chassis includes an engagement protrusion that is engaged to and fastened with the slider when the elastic band is elastically curved.

### Claim 3 (depends on 1)

The electronic apparatus according to claim 1, wherein
the main body upper surface includes a touch pad at a position on a front part of the main body chassis and closer to a left thereof than to a center thereof when viewed from an operator side, and
the puller mechanism is to a right of the touch pad.

### Claim 4 (depends on 1)

The electronic apparatus according to claim 1, wherein
the puller mechanism is at a right end portion on a front part of the keyboard chassis in a left-right direction when viewed from an operator side, and
a left end of the elastic band is fixed to the slider, and a right end of the elastic band is fixed to the keyboard chassis.

### Claim 5 (depends on 4)

The electronic apparatus according to claim 4, wherein
the keyboard has a plurality of cursor keys on a right end front portion of the main body chassis when viewed from the operator side, and
the puller mechanism has a width in the left-right direction when viewed from the operator side that matches a width of the plurality of cursor keys.

### Claim 6 (depends on 4)

The electronic apparatus according to claim 4, wherein
the keyboard is engaged with the main body chassis by a protrusion being fitted into a recess on a rear part of the main body chassis when viewed from the operator side.

### Claim 7 (depends on 1)

The electronic apparatus according to claim 1, wherein
the keyboard is attracted to and fixed to the main body chassis by magnets.

### Claim 8 (depends on 1)

The electronic apparatus according to claim 1, wherein
the keyboard includes a pogo pin on a lower surface thereof, and the pogo pin is electrically connected to a pogo pin connector in the recessed portion.

### Claim 9

A keyboard that is attachable to and detachable from a main body chassis of an electronic apparatus, the keyboard comprising:
a pogo pin on a lower surface of the keyboard wherein
a pogo pin connector is on a mounting portion of the keyboard in the main body chassis, and
the keyboard is mounted on the mounting portion so that the pogo pin and the pogo pin connector are electrically connected.
