Abstract
A medium conveying apparatus includes a motor, a medium tray, a roller, and a processor to control the motor so that the medium tray is located at a position at which the medium placed on the uppermost side of the media placed on the medium tray abuts on the roller each time a particular number of media of the media placed on the medium tray is conveyed, and detect a position of the placing surface. The processor sets the torque of the motor to a first torque when a position of the placing surface is a first position, and sets the torque of the motor to a second torque smaller than the first torque when a position of the placing surface is a second position above the first position.
Claims15
A medium conveying apparatus comprising:
- a motor in which a setting of a torque can be changed according to a supplied power;
- a medium tray provided on a housing and to be raised, and including a placing surface;
- a roller to abut on a medium placed on the medium tray to convey the medium;
- and
- a processor to
- control the motor so that the medium tray is located at a position at which the medium placed on the medium tray abuts on the roller, each time a particular number of media placed on the medium tray is conveyed, and
- detect a position of the placing surface, wherein
- the processor sets the torque of the motor to a first torque when the placing surface is in a first position, and sets the torque of the motor to a second torque smaller than the first torque when the placing surface is in a second position above the first position, and wherein
- a gap between the housing where the medium tray is provided and the medium tray is exposed to an outside of the medium conveying apparatus, during conveying the medium.
A medium conveying method performed by a medium conveying apparatus comprising:
- conveying a medium by a roller placed on a placing surface of a medium tray;
- controlling a motor in which a setting of a torque can be changed so that the medium tray is located at a position at which the medium placed on the medium tray abuts on the roller each time a particular number of media placed on the medium tray is conveyed;
- detecting a position of the placing surface;
- and
- setting the torque of the motor to a first torque when the placing surface is in a first position, and setting the torque of the motor to a second torque smaller than the first torque when the placing surface is in a second position above the first position, wherein
- a gap between a housing where the medium tray is provided and the medium tray is exposed to an outside of the medium conveying apparatus during conveying the medium.
A computer-readable, non-transitory medium storing a computer program, wherein the computer program causes a medium conveying apparatus including a motor in which a setting of a torque can be changed, a medium tray provided so as to be raised and including a placing surface, a roller to convey a medium to execute a process, the process comprising:
- conveying the medium by the roller placed on the medium tray;
- controlling a motor in which a setting of a torque can be changed so that the medium tray is located at a position at which the medium placed on the medium tray abuts on the roller each time a particular number of media placed on the medium tray is conveyed;
- detecting a position of the placing surface;
- and
- setting the torque of the motor to a first torque when the placing surface is in a first position, and setting the torque of the motor to a second torque smaller than the first torque when the placing surface is in a second position above the first position, wherein
- a gap between a housing where the medium tray is provided and the medium tray is exposed to an outside of the medium conveying apparatus during conveying the medium.
