The rotary portion is located on the first surface, and the rotary portion has a function of rotating over the main body.

## Claims

### Claim 1

A cell phone, comprising:
a main body having a first surface; and
a rotary element installed in the main body and comprising a rotary portion, wherein the rotary portion is located on the first surface and has a function of rotating over the main body.

### Claim 2 (depends on 1)

The cell phone according to claim 1, wherein the main body further comprises a camera lens located on the first surface, and the rotary portion is located near the camera lens.

### Claim 3 (depends on 1)

The cell phone according to claim 1, wherein the main body further comprises a second surface opposite to the first surface and a screen located on the second surface.

### Claim 4 (depends on 1)

The cell phone according to claim 1, further comprising at least one protruding piece fixed on the rotary portion, wherein the rotary portion is located between the protruding piece and the main body.

### Claim 5 (depends on 4)

The cell phone according to claim 4, wherein the rotary portion is a disc, and the protruding piece is located near an edge of the disc.

### Claim 6 (depends on 4)

The cell phone according to claim 4, wherein the protruding piece and the rotary portion are formed as an integral unit.

### Claim 7 (depends on 1)
