Abstract

PROBLEM TO BE SOLVED: To realize regular printing even if a total height size is reduced and a recording medium is collected in a medium collection case. SOLUTION: When a recording medium 1 left in an insertion port 2 is stored in a medium collection case 24, a collection roller 17 is stopped in a state where collection rollers 17 sandwiches the recording medium 1. Thus, a state where the recording medium 1 protrudes above the medium collection case 24 is avoided. Consequently, a wasteful space in the upper space of the medium collection case 24 is not formed and the total height size is reduced. Only main transportation rollers 4-8 are driven and regular printing is realized even in a collection state where the recording medium 1 is sandwiched by the collection rollers 17.

Here, the operation performed by the normal print control means will be described. When the recording medium 1 is inserted from the insertion slot 2, the recording medium 1 is pulled in by the main transport rollers 4 to 8 that are driven to rotate forward, and the recording medium 1 is moved to the magnetic read / write unit 20.
, The main transport rollers 4 to 8 are temporarily stopped, the data written on the magnetic stripe of the recording medium 1 is read by the magnetic read / write unit 20, and after this read operation, the main transport rollers 4 to 8 are rotated forward again. Then, when the recording medium 1 passes through the CCD 21, the page mark and the printed line of the recording medium 1 are read by the CCD 21. By this reading, the print position of the print medium 1 is confirmed. When the print position reaches the front of the dot printer head 12, the main transport rollers 4 to 8 are stopped, and predetermined data is printed by the dot printer head 12. . When printing is performed over a plurality of lines, the recording medium 1 is fed by the main transport rollers 4 to 8 every time one line is printed. In this case, as shown in FIG. 7, the switching member 19 is positioned so that the rear portion of the main transport path 3 is opened and the medium recovery path 14 is closed.

When the printing of the predetermined data is completed, the main transport rollers 4 to 8 are reversed to return the recording medium 1 to the insertion slot 2 side. In this process, when the recording medium 1 passes through the CCD 21, the density of the characters printed on the recording medium 1 is determined based on the reading result of the CCD 21, and when the recording medium 1 reaches the magnetic read / write unit 20, the main transport roller 4 to 8 are stopped, and the recording medium 1 is
After the rewriting operation is completed, the main transport rollers 4 to 8 are reversed to return the recording medium 1 to the insertion slot 2. At this time, the collecting rollers 16 and 17, which share a motor with the main transport rollers 4 to 8, always rotate simultaneously with the main transport rollers 4 to 8, and the rotation direction is switched at the same time as the main transport rollers 4 to 8.

Next, the operation performed by the collection control means will be described. As described above, the recording medium 1 returned to the insertion slot 2 is picked up by the customer. However, if the customer forgets to take it, the insertion port sensor 22 continues to output a detection signal for detecting the presence of the recording medium 1. When the time for outputting the detection signal exceeds a predetermined time, it is recognized that the customer has forgotten to take the recording medium 1, and based on this recognition, the main transport roller 4
8 is reversed, and the recording medium 1 is drawn toward the medium recovery storage 15. At this time, the collection rollers 16 and 17 also rotate.

Means, the switching member is actuated when the recording medium printed based on the detection signal of the insertion port sensor provided in the insertion port is present in the insertion port for a predetermined time or more, A collection control unit that opens a body collection path and collects the recording medium in the medium collection container by the main transport member and the collection roller; and when the recording medium is collected, the collection roller is an arbitrary one of the recording medium. The apparatus includes a collection sensor for detecting a state of holding the position, and collection roller stop control means for stopping the collection roller based on a detection signal of the collection sensor.

Therefore, when collecting the recording medium remaining in the insertion slot into the medium collection box, the collection sensor detects that the collection roller for conveying the recording medium toward the medium collection box still holds the recording medium. Then, the collection roller is stopped. This makes it possible to reduce the height of the medium collection box by a height corresponding to the distance from the portion of the recording medium held by the collection roller to the lower end. Further, since the main transport member and the recovery roller are driven by independent motors, it is possible to perform normal printing by driving only the main transport member in a state where the recording medium is recovered in the medium recovery storage.

According to a second aspect of the present invention, in the first aspect of the invention, the collection roller is connected to the motor via a one-way clutch.

Therefore, when the recording medium is taken out from the medium collection box, the resistance received from the collection roller is reduced.

According to a third aspect of the present invention, in the first or the second aspect of the present invention, when the booklet passes the binding portion of the booklet as the recording medium in a direction perpendicular to the sheet-passing direction, The page portion below the binding portion of the booklet is disposed so as to detect a state where the page portion is nipped by the collection roller, and the medium collection box is configured such that when the collection roller stops, the binding portion of the booklet The upper part is open in the direction in which the upper page part falls inside the spine.

Therefore, when collecting the booklet remaining in the insertion slot into the medium collection box, the collection sensor detects that the collection roller is still nipping the page portion below the binding portion of the booklet, and the collection roller detects the state. Although it is stopped, it is possible to turn the portion of the page above the binding portion of the booklet inside the spine.
Therefore, it is possible to further lower the height of the medium collection box by the amount of the booklet.
