Abstract
Disclosed herein is a medium conveying apparatus in which the time for unjamming can be shortened. The medium conveying apparatus includes rollers configured to convey a card Ca, a rotary unit F provided in a medium conveyance path and configured to hold and rotate the card Ca, a sensor SN26 arranged downstream the rotary unit F on the medium conveyance path and, and a control section. The control section controls a first card-conveyance motor for driving the rollers to convey the card Ca into the rotary unit F, and determines whether the sensor SN26 detects the card Ca. The sensor SN26 is arranged at the same distance as a sensor SN3 or a shorter distance than the sensor SN3, from the rotary unit F.
Claims12
A medium conveying apparatus comprising:
- a conveyance section configured to convey a medium;
- a first conveyance path configured to convey the medium,
- a second conveyance path arranged to cross the first conveyance path and configured to convey the medium,
- a direction changing section provided at a point between the first conveyance path and the second conveyance path and configured to change a direction in which the medium is conveyed;
- a first sensor arranged downstream the direction changing section, on the first conveyance path;
- a second sensor arranged upstream the direction changing section, on the first conveyance path;
- and
- a control section configured to control the conveyance section and the direction changing section,
- wherein the control section controls the conveyance section, thereby to convey the medium into the direction changing section, and determines whether the first sensor has detected the medium, and
- wherein the control section judges whether the medium is detected by the first sensor at a time when the medium is transferred for a preset distance since the second sensor detects the medium, and if the medium is not detected by the first sensor, the control section actuates the direction changing section to direct the medium to the second conveying path to convey the medium to the second conveying path.
A medium conveying apparatus comprising:
- a conveyance section configured to convey a medium;
- a direction changing section provided on a medium conveyance path of the conveyance section and configured to change a direction in which the medium is conveyed by the conveyance section;
- a first sensor arranged downstream the direction changing section, on the medium conveyance path;
- a control section configured to control the conveyance section and the direction changing section;
- and
- a second sensor arranged on a circumference of the direction changing section and on another medium conveyance path for conveying the medium in another direction different from that of the medium conveyance path;
- and in which the first sensor is arranged at a same distance from the direction changing section as the second sensor, or at a shorter distance from the direction changing section than the second sensor,
- wherein the control section controls the conveyance section, thereby to convey the medium into the direction changing section, and determines whether the first sensor has detected the medium, and
- wherein unless the first sensor detects the medium conveyed into the direction changing section, conveyed for a preset distance therein and stopped therein, the control section first controls the conveyance section and the direction changing section, thereby changing the direction of conveying the medium toward the another medium conveyance path, then controls the conveyance section, thereby conveying the medium toward the second sensor arranged on the another medium conveyance path, and further detects the distance the medium has been conveyed from a time when the conveyance section starts conveying the medium to a time when the second sensor detects the medium.
