## Abstract

An image forming apparatus has a speaker that is stored inside a housing and includes an attachment guide to which the speaker is attached on a housing front surface. The attachment guide has at least one angle deciding portion which inclines a front surface of the speaker relative to the housing front surface.

## Claims

### Claim 1

An image forming apparatus in which a speaker is stored inside a housing, the image forming apparatus comprising
an attachment guide to which the speaker is attached on an inside surface of the housing, and
an enclosure which encloses a back surface of the speaker, wherein
the attachment guide has at least one angle deciding portion which inclines a front surface of the speaker relative to the inside surface of the housing, and is formed with a guide inside surface along an outer edge of the speaker, and is arranged inside housing front surface above a stacking tray,
the enclosure has a contact portion and the contact portion engages with a guide outside of the attachment guide, and
wherein a portion of the housing front surface corresponding to the attachment guide is inclined in the height direction so as to project outward in the horizontal direction.

### Claim 2 (depends on 1)

The image forming apparatus according to claim 1, wherein
the inside surface of the housing is formed with a plurality of sound holes penetrating from inside to outside at a position facing the front surface of the speaker.

### Claim 3 (depends on 2)

The image forming apparatus according to claim 2, wherein
the outside surface of the housing on which the attachment guide is provided is inclined so as to protrude to outside toward an upper side in a height direction.

### Claim 4 (depends on 2)

The image forming apparatus according to claim 2, wherein
each of sound holes has a rectangular shape in which any one side is formed to be longer than a side adjacent thereto.

### Claim 5 (depends on 4)

The image forming apparatus according to claim 4, wherein
each of sound holes has a longitudinal direction set to be inclined relative to a horizontal direction.

### Claim 6 (depends on 1)

The image forming apparatus according to claim 1, wherein
the front surface of the speaker is inclined so as to be separated from the inside surface of the housing toward an upper side in a height direction.
