Abstract
According to an embodiment, a paper feed device includes: a tray that has a support surface on which a sheet is placed and is capable of entering a first state and a second state. The first state is a state for placing the sheet on the support surface. The second state is a state for taking out the sheet from the support surface toward a downstream side in a conveying direction and for putting the sheet in an inclined posture heading upward on the downstream side in the conveying direction than an upstream side in the conveying direction.

A paper feed device, comprising:
- a tray that has a support surface on which a sheet is placed and is capable of entering a first state and a second state, the first state being a state for placing the sheet on the support surface, the second state being a state for taking out the sheet from the support surface toward a downstream side in a conveying direction and for putting the sheet in an inclined posture heading upward on the downstream side in the conveying direction than an upstream side in the conveying direction;
- a first roller that takes out the sheet from the tray to the downstream side in the conveying direction;
- a second roller that conveys the sheet taken out by the first roller to the downstream side in the conveying direction;
- and
- a third roller that is provided to face the second roller and forms a nip sandwiching the sheet between the third roller and the second roller, wherein
- an angle between a reference line and the sheet on the support surface of the tray in the second state is smaller than an angle between the reference line and the sheet on the support surface of the tray in the first state, the reference line connecting a contact position and the nip to each other, the first roller being in contact with the sheet at the contact position.

An image processing apparatus, comprising:
- a printer device that forms an image on a sheet;
- and
- a paper feed device that feeds the sheet to the printer device, wherein
- the paper feed device includes
- a tray that has a support surface on which the sheet is placed and is capable of entering a first state and a second state, the first state being a state for placing the sheet on the support surface, the second state being a state for taking out the sheet from the support surface toward a downstream side in a conveying direction and for putting the sheet in an inclined posture heading upward on the downstream side in the conveying direction than an upstream side in the conveying direction,
- a first roller that takes out the sheet from the tray to the downstream side in the conveying direction,
- a second roller that conveys the sheet taken out by the first roller to the downstream side in the conveying direction, and
- a third roller that is provided to face the second roller and forms a nip sandwiching the sheet between the third roller and the second roller, and
- an angle between a reference line and the sheet on the support surface of the tray in the second state is smaller than an angle between the reference line and the sheet on the support surface of the tray in the first state, the reference line connecting a contact position and the nip to each other, the first roller being in contact with the sheet at the contact position.
