Abstract
A magnetic ink reading device includes a housing having a slot through which a medium is inserted, a roller driven by a motor by which the medium is conveyed along a conveyance path, one or more sensors arranged along the conveyance path and configured to detect the medium at one or more respective positions, a magnetic head configured to read a magnetic pattern formed on the medium with magnetic ink, and a controller. The controller is configured to control the motor to convey the medium inserted through the slot, measure a length in a conveyance direction of the medium using outputs from the sensors, and control the magnetic head to read the magnetic pattern from the medium while controlling the motor to continuously convey the medium for a period corresponding to the measured length.
Claims20
A magnetic ink reading device, comprising:
- a housing having a slot through which a medium is inserted;
- a roller driven by a motor to convey the medium along a conveyance path in a conveyance direction;
- one or more sensors along the conveyance path at one or more sensor positions and configured to detect the medium at the one or more sensor positions;
- a magnetic head configured to read a magnetic pattern formed on the medium with magnetic ink;
- and
- a controller configured to:
- control the motor to convey the medium inserted through the slot,
- measure a length, in the conveyance direction, of the medium using outputs from the one or more sensors, and
- control the magnetic head to read the magnetic pattern on the medium while controlling the motor to continuously convey the medium for a period corresponding to the measured length.
A printer, comprising:
- a print head configured to print on a medium;
- a housing having a slot through which the medium is inserted;
- a roller driven by a motor by which the medium is conveyed along a conveyance path in a conveyance direction;
- one or more sensors along the conveyance path at one or more sensor positions and configured to detect the medium at the one or more sensor positions;
- a magnetic head configured to read a magnetic pattern formed on the medium with magnetic ink;
- and
- a controller configured to:
- control the motor to convey the medium inserted through the slot,
- measure a length, in the conveyance direction, of the medium using outputs from the one or more sensors,
- control the magnetic head to read the magnetic pattern on the medium while controlling the motor to continuously convey the medium for a period corresponding to the measured length, and
- control the print head to print on the medium according to the magnetic pattern read from the medium by the magnetic head.
A method for controlling a magnetic ink reading device, the method comprising:
- conveying a medium inserted through a slot of a housing along a conveyance path;
- detecting the presence of the conveyed medium with one or more sensors along the conveyance path at one or more sensor positions;
- measuring a length, in a conveyance direction, of the medium using outputs from the one or more sensors;
- and
- reading a magnetic pattern on the medium using a magnetic head while continuously conveying the medium past the magnetic head for a period of time corresponding to the measured length.
