Claim:
An apparatus, comprising: a case defining a conveyance path therein, the path defining a recording medium entrance and a recording medium exit, the path further being configured for a recording medium to be conveyed along the path from the entrance to the exit; a recorder disposed adjacent the conveyance path and configured to record information on the recording medium; a pair of first conveyance rollers configured to convey the recording medium from the recording medium entrance to a position farther downstream the conveyance path; a pair of second conveyance rollers configured to discharge the recording medium from within the conveyance path out through the recording medium exit; a first recording medium detector adjacent the conveyance path downstream of the first conveyance rollers, configured to detect whether the recording medium is present; a second recording medium detector adjacent the conveyance path upstream of the second conveyance rollers and downstream of the first recording medium detector, configured to detect whether the recording medium is present; a third recording medium detector downstream of the recording medium exit adjacent a line extending from the conveyance path, configured to detect whether the recording medium is present; and a device for determining that the recording medium has been removed from the conveyance path past the third recording medium detector when the recording medium detectors change from a first state, in which the second recording medium detector detects that the recording medium is present, to a second state, in which none of the recording medium detectors detect that the recording medium is present, without requiring the third recording medium detector to detect that the recording medium is present during the state change.
