Abstract
Disclosed herein is a medium conveying apparatus in which unjamming can be efficiently performed. The medium conveying apparatus includes conveyance rollers configured to convey a card, a rotary unit configured to hold and rotate the card, sensors SN2 and SN26 configured to detect the distance the card has been conveyed, and a control section. If the distance the card has been conveyed that has been detected by the sensors SN2 and SN26 differs from a preset distance L1 (Yes in Step S320), the control section determines (in S328 and S336) whether the card can be positioned in a direction to be delivered from the rotary unit. If the card can be so positioned, a drive motor is controlled, rotating the rotary unit to position the card to be delivered.
Claims11
A medium conveying apparatus comprising:
- a conveyance section configured to convey a medium;
- a direction changing section configured to change a direction in which the medium is conveyed by the conveyance section;
- a detection section configured to detect a distance the medium has been conveyed by the conveyance section;
- and
- a control section configured to control the direction changing section,
- wherein if the distance detected by the detection section is shorter than a preset distance L1, the control section determines whether the medium can be positioned in such a direction as to be delivered from the direction changing section, and if the medium can be so positioned, the control section controls the direction changing section to position the medium in said direction.
An image forming apparatus comprising:
- a conveyance section configured to convey a medium;
- a direction changing section configured to change a direction in which the medium is conveyed by the conveyance section;
- a detection section configured to detect a front end and a rear end of the medium conveyed by the conveyance section;
- an image forming section configured to form an image on the medium;
- and
- a control section configured to control the conveyance section, the direction changing section, the detection section, and the image forming section,
- wherein the control section controls the detection section to detect the front end and the rear end of the medium, thereby calculating a medium length from the front end to the rear end of the medium conveyed by the conveyance section,
- if the medium length is longer than a preset distance L, the control section determines whether the medium can be positioned in such a direction as to be delivered from the direction changing section, and if the medium can be so positioned, the control section controls the direction changing section to position the medium in said direction, and
- if the medium length is equal to or shorter than the preset distance L, the control section controls the conveyance section to convey the medium to the image forming section and controls the image forming section to form the image on the medium.
A medium conveying apparatus comprising:
- a conveyance section configured to convey a medium;
- a direction changing section configured to change a direction in which the medium is conveyed by the conveyance section;
- a detection section configured to detect a front end and a rear end of the medium conveyed by the conveyance section;
- and
- a control section configured to control the conveyance section, the direction changing section, and the direction changing section,
- wherein the control section controls the detection section to detect the front end and the rear end of the medium, thereby calculating a medium length from the front end to the rear end of the medium conveyed by the conveyance section,
- if the medium length is longer than a preset distance L3, the control section determines whether the medium can be positioned in such a direction as to be delivered from the direction changing section, and if the medium can be so positioned, the control section controls the direction changing section to position the medium in said direction.
