Further, the stacker tray 101 is provided with a shutter 152 on the upper left side at the rear end thereof, and this shutter 152 is erected so as to block a part of the gap 151 on the stacker tray 101. . The width of the gap 151 communicating with the label printer 11 is made smaller than the outer diameter of the medium M by the shutter 152.

  This prevents a problem that the medium M enters the processing unit storage space A2 in which the label printer 11 is stored from the media storage space A1 side through the gap 151. That is, it is possible to prevent the malfunction of the label printer 11 caused by the user accidentally dropping the medium M into the processing unit storage space A2 with the open / close door 3 opened. .

The shutter 152 is made of a resin plate, and moves substantially horizontally along the moving direction of the media tray 51 around the horizontal axis perpendicular to the moving direction of the media tray 51 above the stacker tray 101 and the movement of the media tray 51. It is supported so as to be rotatable between a substantially vertical plane intersecting the direction.
Further, the shutter 152 is urged toward the rear side in the protruding direction to the media storage space A1 of the media tray 51 by a winding spring (biasing means) 153 provided on the rotating shaft. The shutter 152 is disposed substantially vertically, and a part of the gap 151 is closed.

  Then, when the media tray 51 of the label printer 11 projects from the gap 151 toward the media storage space A1 in order to feed the media M to the ejection media stacker section 103, as shown in FIG. 19, the end surface of the projecting media tray 51 Comes into contact with the shutter 152. As a result, the shutter 152 is rotated forward in the protruding direction of the media tray 51 against the biasing force of the winding spring 153, and the media tray 51 moves above the tilted shutter 152 as shown in FIG. To do.

When the protruding media tray 51 is pulled into the gap 151, the shutter 152 that has been rotated and tilted by the media tray 51 is rotated rearward in the protruding direction of the media tray 51 by the urging force of the winding spring 153. Therefore, the medium M is prevented from entering the gap 151.
Here, the media tray 51 has a pressing portion 51b made of a protrusion formed in an arc shape in cross section at a sliding position with the shutter 152. The shutter 152 has a pressing portion 51b of the media tray 51. It smoothly slides and rotates while making line contact with the arcuate outer surface of the. As a result, the media tray 51 can be moved smoothly while minimizing resistance caused by friction.

In addition, it is preferable that the shutter 152 be separated from the contact position with the media tray 51 as much as possible. In this way, the rotational moment of the shutter 152 is reduced and the contact resistance with the media tray 51 is further reduced. can do.
Note that the shutter 152 may be rotated in non-contact with the media tray 51 in conjunction with the movement of the media tray 51, and in this way, resistance when the media tray 51 is moved due to contact with the shutter 152. And the load fluctuation of the media tray 51 can be prevented.

As described above, according to the publisher that is the media processing apparatus according to the above-described embodiment, the shutter that can be opened and closed in the gap 151 serving as the passage of the media tray 51 between the media storage space A1 and the processing unit storage space A2. Since 152 is provided, it is possible to prevent the medium M from entering the processing unit storage space A2 in which the label printer 11 is stored from the media storage space A1 through the gap 151.
As a result, problems such as malfunction in the label printer 11 due to the medium M entering the processing section storage space A2 side can be eliminated, and processing on the medium M can be performed satisfactorily.

  The shutter 152 is sized to block at least a part of the gap 151, and the gap 151 has a width smaller than the outer diameter of the medium M by the shutter 152. Therefore, a shutter that opens and closes the entire gap 151 is provided. As compared with the case where the shutter 152 is provided, the structure of the shutter 152 can be simplified, and the entry of the medium M into the gap 151 can be prevented. Further, the shutter 152 can be reduced in size, and the shutter 152 can be easily opened and closed. it can.

Further, since the shutter 152 rotates in conjunction with the movement of the media tray 51 around an axis orthogonal to the moving direction of the media tray 51, the gap 151 can be easily opened and closed by rotating the shutter 152. .
In addition, since the shutter 152 is pressed and rotated by the media tray 51 that moves to the media storage space A1, the shutter 152 is easily rotated by the moving media tray 51 without providing a separate drive mechanism, and the gap 151 Can be opened and closed.

  In addition, since the shutter 152 is urged by the winding spring 153 to the rear side in the moving direction of the media tray 51 toward the media storage space A1, the shutter 152 rotated in the direction to open the gap 151 is moved to the winding spring 153. Thus, the gap 151 can be closed by easily rotating in the reverse direction.

Furthermore, since the pressing portion 51b that is in line contact with the shutter 152 is formed on the media tray 51, the contact resistance between the media tray 51 and the shutter 152 can be greatly reduced, and the rotation operation of the shutter 152 is made smooth. In addition, the load fluctuation in the media tray 51 can be reduced.
The media tray 51 may be formed with a pressing portion 51b made of a hemispherical protrusion instead of a protrusion having an arcuate cross section and brought into point contact with the shutter 152. In this case also, the media tray 51 and the shutter 152 The contact resistance with can be reduced.

Further, for example, by forming the media tray 51 from modified polyphenylene ether and forming the shutter 152 from polyoxymethylene (POM), the contact resistance between the media tray 51 and the shutter 152 is further reduced, and the media tray 51 Can be further smoothed.
Even if the media tray 51 is molded from polyoxymethylene (POM) and the shutter 152 is molded from modified polyphenylene ether, the contact resistance between the media tray 51 and the shutter 152 is reduced, so that the media tray 51 can move more smoothly. Can be achieved.

Note that the shutter 152 is not limited to a plate shape, and may be a rod shape, and a plurality of installation quantities may be used.
In the above embodiment, the case where the shutter 152 is provided in the gap 151 between the processing unit storage space A2 in which the label printer 11 is stored and the media storage space A1 has been described as an example, but the processing in which the drive 41 is stored is described. When there is a gap between the part storage space and the media storage space A1, it is desirable to provide a shutter in the gap.
