Claims

A supply unit that separates a plurality of recording media one by one and then conveys the recording medium through a supply path;
An image recording unit for recording an image on the recording medium;
A resupply unit that re-supplies and conveys the recording medium image-recorded on the first surface on the front surface of the recording medium by the image recording unit to the image recording unit in order to record an image on the second surface on the back surface. When,
A registration unit that is disposed upstream of the image recording unit in the supply path and performs at least alignment with the recording medium conveyed from the supply unit or the re-supply unit;
A transport mechanism that is provided opposite to the image recording unit and includes at least a transport information generating unit for generating transport information of the recording medium;
A storage unit that conveys and stores the recording medium on which only the first surface is imaged, or the recording medium on which the image is recorded on the first and second surfaces;
A reversing path unit having a reversing mechanism for conveying the recording medium image-recorded on the first surface by the image recording unit to the re-feeding unit;
A control unit that controls at least each conveyance operation of the recording medium;
Comprising at least
Wherein the control unit, the page gap value of the recording medium subsequent to the recording medium the preceding during each conveyance of the recording medium, the continuous two-sided recording, or continuous single-sided recording, or continuous duplex recording and single-sided recording, respectively the image recording apparatus characterized by setting for each record.

The image recording apparatus according to claim 1, wherein the storage unit includes a first path switching unit for guiding the recording medium to the storage unit or the reverse path unit.

The image recording apparatus according to claim 1, wherein the reversing path unit includes a second path switching unit for guiding the recording medium to the reversing mechanism or the refeeding unit.

Continuously feeding a plurality of recording media, the trailing edge of the preceding said recording medium with a predetermined amount or more pages gap value to pass finish timing of the first position, the tip of the recording medium subsequent to the said Set a first condition to reach the storage unit for transporting and storing the recording medium ;
In order to record an image on the back side of the recording medium supplied to the recording medium or on the front side of the recording medium upstream of the image recording unit for recording an image on the recording medium, the recording medium is again applied to the image recording unit. The preceding recording medium and the succeeding recording medium do not exist at the same time in the re-supply unit to be supplied , and a predetermined amount or more is reached when the trailing end of the preceding recording medium passes through the second position. Maintaining the page gap value, and setting a second condition for the leading edge of the subsequent recording medium to reach the supply unit or the re-supply unit ,
The preceding recording medium and the succeeding recording medium do not exist at the same time at the position of the reversing mechanism that reverses the first surface on the front surface of the recording medium to the second surface on the back surface of the recording medium, and the preceding A third condition in which a page gap value of a predetermined amount or more is maintained at a timing when the trailing end of the recording medium passes through the third position and the leading end of the succeeding recording medium reaches the position of the reversing mechanism. Set
In the case of single-sided recording in which an image is recorded only on the first surface of the surface of the recording medium,
Before SL first condition, and determines the conveyance start timing of the recording medium subsequent to based on the second condition is satisfied scheduling,
In the case of double-sided recording in which images are recorded on both sides including the first surface on the front surface of the recording medium and the second surface on the back surface of the recording medium,
Before SL first condition, the second condition, and on the basis of the third condition is satisfied scheduling, an image recording method characterized by determining the conveyance start timing of the subsequent said recording medium.

When the double-sided recording and said one side recording is a recording process in continuous, pre-Symbol first condition, the second condition, and on the basis of the third condition is satisfied scheduling of subsequent said recording medium The image recording method according to claim 4, wherein a conveyance start timing is determined.

The image recording method according to claim 4, wherein the page gap value in the case of the double-sided recording is set to a page gap value larger than the page gap value in the case of the single-sided recording.

Further, the storage unit includes a pair of discharge / conveyance rollers for conveying or discharging the recording medium,
