The insertion prevention member 29 extends along the length direction of the insertion port 23, and the end portion facing the insertion / removal portion 16 is inclined from the shaft 26 side toward the free end side opposite thereto in plan view. It is an inclined part. When the optical disk D is inserted upright along the transport path 15 from the insertion / removal unit 16, the bottom surface of the optical disk D is in contact with the guide surface 15 a on the bottom surface of the transport path 15. The outer edge on the lower half side of the insertion end side abuts against the inclined portion, and at this abutment, the insertion prevention member 29 rotates counterclockwise around the shaft 26 against the spring 29a and The lower side is opened, so that the optical disk D can be inserted into the loading unit 6.
When the insertion opening cover 24 is manually slid to the rear side of the apparatus main body 2 to open the insertion opening 23, and the optical disk D is erroneously inserted from the upper side of the apparatus main body 2 through the insertion opening 23 in this state, the optical disk D hits the insertion prevention member 29 from directly above, whereby the optical disc D is received by the insertion prevention member 29 and further insertion into the apparatus main body 2 is prevented.

  In the printing apparatus 1, the platen roller 7 and the thermal head 8 are erected in the loading unit 6 so as to face the conveyance path 15. When the ink ribbon cassette 85 is loaded in the loading section 6 and printing is performed on the optical disk D, the ink ribbon 87 of the ink ribbon cassette 85 is set to be perpendicular to the width direction from the upstream side to the downstream side of the transport path 15. It is conveyed in the horizontal direction.

  When the optical disc D is inserted from the insertion / removal unit 16 along the conveying path 15 in the standing state toward the apparatus main body 2, the ink surface of the ink ribbon 87 and the label surface (printing surface) of the optical disc D face each other, and Since the transport direction (ribbon feeding direction) of the ink ribbon 87 and the insertion direction of the optical disk D are parallel, there is no possibility that the optical ribbon D will be caught by the optical disk D when the optical disk D is inserted into the apparatus main body 2. That is, the optical disk D is inserted into the apparatus main body 2 in a direction parallel to the direction of feeding of the ink ribbon 87, and therefore the ink ribbon 87 is smoothly inserted without twisting or damaging the ink ribbon 87.

  On the other hand, if the optical disk D is erroneously inserted into the apparatus main body 2 in an upright state from the upper side of the apparatus main body 2 through the insertion port 23, the ink surface of the ink ribbon 87 and the label surface of the optical disk D face each other, and the ink ribbon The conveyance direction (ribbon feeding direction) 87 and the insertion direction of the optical disk D are orthogonal to each other. Thus, if the ribbon feeding direction and the insertion direction of the optical disk D are orthogonal, the ink ribbon 87 may be caught and damaged when the optical disk D is inserted. In this printing apparatus 1, the optical disc D is inserted from the direction orthogonal to the ink ribbon transport direction (ribbon feeding direction) by providing the insertion preventing member 29 facing the insertion port 23. It is preventing.

  Next, the tape cassette 70 and the ribbon cassette 85 loaded in the loading unit 6 will be further described with reference to FIGS.

The push plate 57 is located between the lower end portion of the protrusion 24 a provided on the lower surface of the insertion port cover 24 and the engagement pin 66 of the rotating lever 64 and the engagement pin 66. 66 is arranged vertically so as to face both of them, and is held in a state where it can be translated in the front-rear direction of the apparatus main body 2.

  Normally, as shown in FIG. 22A, the insertion port cover 24 is held at a position where the insertion port 23 is closed. Then, when the optical disc D is inserted into the apparatus main body 2 from the insertion / removal unit 16 in an upright state, the insertion port cover 24 resists the spring 43 as shown in FIG. The insertion port 23 is opened by moving toward the rear side. Further, when the insertion port cover 24 moves toward the rear side of the apparatus main body 2, the protrusion 24 a hits the pressing plate 57, and the pressing plate 57 is integrated with the insertion port cover 24 in the rear side direction of the apparatus main body 2. , The push plate 57 hits the engaging pin 66 of the rotating lever 64, and the rotating lever 64 rotates counterclockwise against the spring 68 in response to this, and the engaging pin 66 Is detached from the cutout portion 40 of the movable blade 32, and the transmission mechanism 60 that transmits the operation of the operating body 37 to the movable blade 32 is shut off.

  Therefore, when the operation body 37 is operated so that the operator pushes the operating body 37 downward with a fingertip as shown in FIG. 23B with the optical disc D of the apparatus main body 2 loaded, the operating body 37 only moves downward. Therefore, the operation is not transmitted to the movable blade 32, and thus the optical disk D is not damaged.

  When printing on the optical disk D is completed and the optical disk D is removed from the apparatus main body 2, the optical disk D is removed from the insertion opening 23, whereby the insertion opening cover 24 is moved forward of the apparatus main body 2 by the biasing force of the spring 43. The rotation lever 64 is rotated in the clockwise direction by the urging force of the spring 68 by this movement, and the push plate 57 is translated in the forward direction of the apparatus main body 2 and the engagement pin 66 is moved.

Unlike the case of printing on the optical disk D, it is not necessary to open the insertion port cover 24. For this reason, the insertion port cover 24 is arranged as it is at the position where the insertion port 23 is closed, and in this state, the printing tape 71 of the tape cassette 70 is used. Is printed. At this time, since the insertion port cover 24 is in a position to close the insertion port 23, it is possible to operate the cutting means 30 by operating the operating body 37, and thus the printed portion of the printing tape 71 is inserted. When the operation unit 37 is pushed downward as shown in FIG. 23A when it is discharged to the removal part 16 and stopped, the movable blade 32 is rotated to rotate the printed part of the printing tape 71. To produce a label.

  As described above, also in the printing apparatus 1 of the seventh embodiment, when the optical disk D is loaded into the apparatus main body 2 through the insertion opening 23, the insertion opening cover 24 is moved by the operation and the insertion opening 23 is moved. At the same time, the transmission mechanism 60 between the operating body 37 and the cutting means 30 is cut off, so that even if the operating body 37 is inadvertently operated, the cutting means 30 does not operate and the optical disk D is damaged. Such inconvenience is not caused.

  In the seventh embodiment, the insertion port cover 24 is interlocked with the loading operation of the optical disk D. However, as in the third and fourth embodiments, the insertion port cover 24 is operated by the operator. When the insertion port cover 24 is moved by the operation of the operator from the position where the insertion port 23 is closed to the position where the insertion port 23 is opened, the movement between the operating body 37 and the cutting means 30 is performed. The transmission mechanism 60 may be shut off so that the operation of the operating body 37 is not transmitted to the cutting means 30.

  The printing apparatus of the present invention has a function of not operating the cutting means for a rigid medium such as a recording medium. However, the rigid medium is not limited to a recording medium such as an optical disk, and is a plastic card. It may be the case.
