## Abstract

An input device according to one of various embodiments of the present disclosure includes a body having an ElectroMagnetic Induction (EMI) circuit, a first contact member reciprocating in the body and associated with the EMI circuit, and a second contact member installed to the body and having at least a part disposed in side by side with the first contact member, the second contact member being made of a conductive material.

## Claims

### Claim 1

An input device comprising: a body having an ElectroMagnetic Induction (EMI) circuit; a first contact member reciprocating in the body and associated with the EMI circuit; and a second contact member installed to the body and having at least a part disposed adjacent to the first contact member, the second contact member being made of a conductive material and the second contact member being electrically isolated from the first contact member, wherein the first contact member transmits a writing pressure to the EMI circuit, and wherein the first contact member is configured to provide a first output to indicate a first event and the second contact member is configured to provide a second output indicating a second event, different from the first event, when the second contact member is depressed.

### Claim 2 (depends on 1)

The input device as claimed in claim 1, wherein the EMI circuit includes a variable capacitive element, and a capacitance of the variable capacitive element is changed as the first contact member moves.

### Claim 3 (depends on 1)

The input device as claimed in claim 1, wherein the first contact member is disposed at one end of the body in a lengthwise direction of the body.

### Claim 4 (depends on 3)

The input device as claimed in claim 3, wherein the second contact member is located adjacent to the first contact member at the one end of the body, and the first and second contact members form a distal end of the input device to be inclined with respect to the lengthwise direction of the body.

### Claim 5 (depends on 3)

The input device as claimed in claim 3, wherein the second contact member is located adjacent to the first contact member at the one end of the body, and the first and second contact members form a distal end of the input device to be inclined with respect to the lengthwise direction of the body and the first contact member protrudes more than the second contact member.

### Claim 6 (depends on 1)

The input device as claimed in claim 1, wherein an intermediate member is installed between the first and second contact members.

### Claim 7 (depends on 1)

The input device as claimed in claim 1, wherein the first contact member comprises a tip member having a point contact structure.

### Claim 8 (depends on 1)

The input device as claimed in claim 1, wherein the second contact member comprises another tip member having a line contact structure or a surface contact structure.

### Claim 9 (depends on 1)

The input device as claimed in claim 1, wherein the second contact member is installed to enclose a portion of an outer peripheral surface of the body.

### Claim 10 (depends on 1)

The input device as claimed in claim 1, wherein the first output comprises an EMI signal and the second output comprises a change in an amount of charge detectable by a touch panel in response to the second contact member coming in contact with the touch panel.

### Claim 11 (depends on 1)

The input device as claimed in claim 1, wherein the input device is configured to allow simultaneous contact between a touch panel and both of the first contact member and the second contact member.

### Claim 12 (depends on 1)

The input device as claimed in claim 1, wherein the second contact member is made of a material having a charge allowing a user to provide an input via the second contact member while wearing a glove.
