Abstract

A recording system includes a first unit configured to transport a medium that is continuous, a recording unit configured to perform recording on the medium transported by the first unit, a second unit configured to transport the medium, a post-processing unit configured to perform predetermined post-processing on the medium transported by the second unit, and a buffer provided between the first unit and the second unit, the buffer being configured to accumulate the medium transported from the first unit and feed the medium to the second unit, wherein in a recording period in which the recording unit performs the recording on the medium, the second unit transports the medium at a first velocity, and in a non-recording period that is after the recording period and in which the recording unit does not perform the recording on the medium.

Claims (31)

1 . A recording system comprising:

a first transport unit configured to transport a medium that is continuous;

a recording unit configured to perform recording on the medium transported by the first transport unit;

a second transport unit configured to transport the medium;

a post-processing unit configured to perform predetermined post-processing on the medium transported by the second transport unit;

a buffer unit provided between the first transport unit and the second transport unit, the buffer unit being configured to accumulate the medium transported from the first transport unit and feed the medium to the second transport unit, wherein

the post-processing unit comprises a velocity control unit,

in a recording period in which the recording unit performs the recording on the medium, the velocity control unit controls the second transport unit to transport the medium at a first transport velocity, and

in a non-recording period that is after the recording period and in which the recording unit does not perform the recording on the medium, the velocity control unit controls the second transport unit to transport the medium at a second transport velocity lower than the first transport velocity.

2 . The recording system according to claim 1 , wherein the second transport velocity is zero.

3 . The recording system according to claim 1 , wherein the post-processing is recording processing of performing second recording on the medium on which the recording is performed by the recording unit.

4 . The recording system according to claim 1 , wherein the post-processing is inspection processing of reading, by a reading unit, the medium on which the recording is performed by the recording unit and inspecting the medium.

5 . The recording system according to claim 1 , wherein the post-processing is cutting processing of cutting the medium on which the recording is performed by the recording unit.

6 . The recording system according to claim 1 , wherein the post-processing is heating processing of heating the medium on which the recording is performed by the recording unit.

7 . The recording system according to claim 1 , wherein

the first transport unit back-feeds the medium until a recording completion position, which is a position of the medium on which the recording by the recording unit is completed, returns to a check position on a transport path of the medium.

8 . A post-processing device that receives a medium transported by a recording device and that performs predetermined post-processing on the medium, the medium being continuous, the recording device being configured to perform recording on the medium, the post-processing device comprising:

a transport unit configured to transport the medium;

a post-processing unit configured to perform the post-processing on the medium transported by the transport unit; and

a buffer unit configured to accumulate the medium transported from the recording device and feed the medium to the transport unit, wherein

the post-processing unit comprises a velocity control unit,

in a recording period in which the recording device performs the recording on the medium, the velocity control unit controls the transport unit to transport the medium at a first transport velocity, and

in a non-recording period that is after the recording period and in which the recording device does not perform the recording on the medium, the velocity control unit controls the transport unit to transport the medium at a second transport velocity lower than the first transport velocity.

9 . A recording system comprising:

a first transport unit configured to transport a medium that is continuous;

a recording unit configured to perform recording on the medium transported by the first transport unit;

a second transport unit configured to transport the medium;

a post-processing unit configured to perform predetermined post-processing on the medium transported by the second transport unit;

a buffer unit provided between the first transport unit and the second transport unit, the buffer unit being configured to accumulate the medium transported from the first transport unit and feed the medium to the second transport unit, wherein

in a recording period in which the recording unit performs the recording on the medium, the post-processing unit controls the second transport unit to transport the medium at a first transport velocity by controlling a rotational speed of a drive motor for the second transport unit, and

in a non-recording period that is after the recording period and in which the recording unit does not perform the recording on the medium, the post-processing unit controls the second transport unit to transport the medium at a second transport velocity lower than the first transport velocity by controlling the rotational speed of the drive motor for the second transport unit.
