an option mounting portion positioned below the keyboard to mount an optional hardware device provided in the protruding portion, the option mounting portion comprising an opening in a front surface of the first part of the protruding portion.

5 . The image forming device of claim 1 , further comprising:

a discharge tray, on which a print medium discharged from the printing portion is to be loaded, provided in the upper surface of the printing portion,

wherein the protruding portion is positioned on one side of the discharge tray in a second direction orthogonal to a first direction which is a movement direction of the keyboard, and

wherein an inner end of the keyboard in the second direction in the storage position is positioned in an upper portion of the discharge tray.

6 . The image forming device of claim 1 , further comprising:

a first rail provided on the keyboard;

a second rail provided on the accommodation portion to guide the first rail so that the keyboard is able to be moved between the storage position and the withdrawal position; and

an elastic arm provided on the first rail to elastically contact the second rail and generate a sliding resistance.

7 . The image forming device of claim 6 , further comprising:

a sliding resistance increasing portion contacting the elastic arm so that the sliding resistance is increased in a case where the keyboard approaches the withdrawal position.

8 . An image forming device comprising:

a printing portion to print an image on a print medium, the printing portion comprising an upper surface including a discharge tray on which the print medium that has undergone printing is to be loaded;

a protruding portion protruding upward from the upper surface of the printing portion and located on one side of the discharge tray, the protruding portion comprising a first part with a front surface stepped inward along a first direction from a front surface of the printing portion and a second part, wherein an accommodation portion recessed from the front surface of the first part of the protruding portion is formed between the first part and the second part; and

a keyboard movable between a storage position inserted into the accommodation portion in the first direction and a withdrawal position withdrawn from the accommodation portion,

wherein the accommodation portion has a first depth in the first direction and a first length in a second direction orthogonal to the first direction,

wherein the keyboard has a second depth in the first direction and a second length in the second direction,

wherein the second length or the second depth is respectively greater than the first length or the first depth, and

wherein, in the storage position, the keyboard is positioned inside an outermost surface of the printing portion.

9 . The image forming device of claim 8 , wherein the first part of the protruding portion is

protruding upward from the upper surface of the printing portion and having a third length in the second direction longer than the first length; and

the second part is positioned on an upper portion of the first part, the second part having the first length in the second direction.

10 . The image forming device of claim 9 , wherein

the first part has a first inner surface adjacent to the front surface of the first part and extending in the first direction and a first outer surface opposing the first inner surface and extending in the first direction,

the second part has a second inner surface adjacent to the front surface of the second part and extending in the first direction and a second outer surface opposing the first inner surface and extending in the first direction, and

the second outer surface is stepped inward along the second direction from the first outer surface.

11 . The image forming device of claim 10 , wherein

an outer end of the keyboard, corresponding to the portion of the keyboard closest to the first and second outer surfaces, is positioned between the first outer surface and the second outer surface with respect to the second direction, and

in the storage position, a front end of the keyboard, corresponding to the portion of the keyboard furthest in the direction that the front surface of the first portion is facing, in the first direction is positioned further inside than the front surface of the printing portion with respect to the first direction.

12 . The image forming device of claim 10 , wherein

a discharge port, through which a print medium that has undergone printing is to be discharged, is provided in the first inner surface, and

an inner end of the keyboard with respect to the second direction in the storage position is positioned on an upper portion of the discharge tray.

13 . The image forming device of claim 10 , further comprising:

a display installed in the second part; and

an option mounting portion comprising an opening formed in the front surface of the first part of the protruding portion to mount an optional hardware device installed in the first part.

14 . An image forming device comprising:

a main body including a recess in a front surface of the main body forming an accommodation portion; and

a keyboard movable between a storage position in which the keyboard is partially stored in the accommodation portion and a withdrawal position in which the keyboard is withdrawn from the accommodation portion,

wherein, in the storage position, a front end of the keyboard with respect to the front surface of the main body and an outer end of the keyboard adjacent to the front end of the keyboard are positioned outside the accommodation portion and inside front and side surfaces of the main body of the image forming device.

15 . The image forming device of claim 14 , wherein the main body comprises:

a printing portion to print an image on a print medium, the printing portion comprising an upper surface including a discharge tray on which the print medium that has undergone printing is to be loaded; and

a protruding portion, protruding upward from the upper surface of the printing portion, on one side of the discharge tray, the protruding portion comprising a front surface in the same orientation as the front surface of the image forming device stepped inward from a front surface of the printing portion in the same orientation as the front surface of the image forming device,
