  Further, the lower end edge of the positioning holding member 20 extends so as to protrude downward by a predetermined length (in this embodiment, about 1 mm to 2.5 mm) than the lower end edge of the guide member 28. In addition, a substantially rectangular sheet discriminating portion 60 extending a predetermined length in a substantially perpendicular inner direction is formed at the lower edge. Further, as shown in FIG. 11, in the sheet discriminating portion 60, as described above, the sensor holes 60A to 60F penetrating at predetermined positions facing the sheet discriminating sensors P1 to P6 are arranged in a substantially L shape. To be formed. In FIG. 11, the sensor holes 60 </ b> A to 60 </ b> C among the sensor holes 60 </ b> A to 60 </ b> F are formed in the sheet determination unit 60.

  As a result, each of the sensor holes 60A to 60F is formed at a maximum of five out of the six, so the presence or absence of each of the sensor holes 60A to 60F is made to correspond to “1” and “0”. The type, material, roll sheet width, and the like of the roll sheet 3A mounted on the holder 3 can be displayed by a 6-bit code “000001” to “111111”. The 6-bit code “000000” indicates that the roll sheet holder 3 is not attached.

Next, a state in which the roll sheet holder 3 configured as described above is attached to the roll sheet holder storage portion 4 and the upper cover 5 is closed will be described with reference to FIGS. 12 and 13.
FIG. 12 is a diagram illustrating a state where the upper end surface of the attachment member 21 of the roll sheet holder 3 is pressed by the holder pressing portion 51 of the upper cover 5. 13 is a cross-sectional view taken along arrow X3-X3 in FIG.

  As shown in FIGS. 12 and 13, when the upper cover 5 is closed, the lower end portion of the tip of the holder pressing portion 51 is attached to the mounting member 21 from the front upper side of the mounting member 21 obliquely upward. Is in contact with the upper end surface of the. In addition, the longitudinal direction of the holder pressing portion 51 is a straight line 67 that connects the contact point between the holder pressing portion 51 and the upper end surface of the mounting member 21 and the axis of the engaging protrusion 52 </ b> A that is the rotation center of the upper cover 5. On the other hand, it is provided so as to be in a substantially orthogonal direction.

  Therefore, the direction of the reaction force received from the mounting member 21 when the holder pressing portion 51 presses the mounting member 21 is the direction of the arrow X4, that is, the rotation axis of the upper cover 5 and the mounting of the holder pressing portion 51. It works in the direction connecting the contact point that contacts the upper end of the member 21. Thereby, the reaction force acting on the tip of the holder pressing portion 51 hardly acts in the direction in which the upper cover 5 is opened.

  Further, by closing the upper cover 5, the link lever 34 moves in the front direction in conjunction with the movement of the upper cover 5, the thermal head support member 37 is moved upward, and the thermal head 32 is rolled by the pressing spring 36. The sheet 3A is pressed and urged against the platen roller 35 to be ready for printing (see FIG. 3). Therefore, at the time of printing the roll sheet 3A, the roll sheet 3A is pulled out with the holder pressing portion 51 pressing the attachment member 21 of the roll sheet holder 3.

  Here, the holder support member 23 functions as a support member. Moreover, the 1st positioning groove part 24 functions as a fitting part. Further, the positioning holding member 20 functions as a reference side holding member. Moreover, the attachment member 21 functions as a to-be-fitted part. Moreover, the sheet | seat discrimination | determination part 60 and each sensor hole 60A-60F comprise a roll sheet specific | specification part.

  Therefore, in the tape printer 1 according to the present embodiment, when the roll sheet holder 3 around which the roll sheet 3A is wound is mounted in the tape printer 1 and the upper cover 5 is closed, the upper cover 5 The provided holder pressing portion 51 comes into contact with the upper end portion of the attachment member 21 fitted in the first positioning groove portion 24 of the holder support member 23. Then, the tip end side of the holder pressing portion 51 is elastically deformed toward the ceiling portion 48 side of the upper cover 5. Thereby, since the attachment member 21 of the roll sheet holder 3 is stably pressed via the holder pressing portion 51, it is possible to reliably prevent the roll sheet holder 3 from being lifted or rattled when the roll sheet 3A is pulled out. Is possible.

  Further, when the holder pressing portion 51 comes into contact with the upper end surface of the mounting member 21 of the roll sheet holder 3, the tip portion is elastically deformed toward the inner wall side of the upper cover 5. For this reason, the roll sheet holder 3 can be stably held via the holder pressing portion 51 with a simple configuration without requiring a biasing member such as a spring for bringing the holder pressing portion 51 into contact with the mounting member 21. It becomes possible to hold down.

  Further, since the holder pressing portion 51 is formed in a flat plate shape having a predetermined width, it can be simplified in structure and has a small pressing force when the upper cover 5 is closed even if the dimensional accuracy is lowered. As a result, the front end portion is elastically deformed toward the inner wall side of the upper cover 5, and the roll sheet holder 3 can be reliably and stably pressed.

  Further, when the upper cover 5 is closed and the holder pressing portion 51 is brought into contact with the mounting member 21, the reaction force acting on the tip of the holder pressing portion 51 is caused by the rotational axis of the upper cover 5. It works in a direction (in the direction of arrow X4 in FIG. 12) connecting the contact point that contacts the upper end surface of the attachment member 21 of the holder pressing portion 51. As a result, the reaction force acting on the tip of the holder pressing portion 51 hardly acts in the direction in which the upper cover 5 is opened, so that it is possible to prevent the upper cover 5 from being accidentally opened. Further, the elastic locking pieces 15 and the locking projections 15A for locking the upper cover 5 to the main body housing 2 and the engaging recesses 16 facing the elastic locking pieces 15 can be reduced in size. As a result, the tape printer 1 can be downsized.

  Further, after the mounting member 21 of the roll sheet holder 3 is positioned and fitted in the first positioning groove portion 24, the upper cover 5 is closed, whereby the upper end portion of the mounting member 21 is held by a holder press provided on the upper cover 5. It is possible to stably press the part 51. For this reason, when the roll sheet 3A is pulled out, the sensor holes 60A to 60F formed in the sheet determination unit 60 provided at the lower end edge of the positioning holding member 20 are lifted and rattled from the sheet determination sensors P1 to P6. It is possible to reliably prevent and accurately specify the type of the roll sheet 3A.

  Furthermore, since the holder pressing part 51 formed on the upper cover 5 made of transparent resin is formed along the mold drawing direction of the upper cover 5 formed by resin molding, the upper cover 5 is made of transparent resin. Even if formed, it is possible to improve the appearance.

In addition, this invention is not limited to the said Example, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.
For example, a slit-shaped notch groove may be formed at a predetermined length along the longitudinal direction at the center in the width direction of the tip of the holder pressing portion 51. Thereby, by adjusting the width and length of the notch groove, it is possible to adjust the pressing force for pressing the upper end portion of the attachment member 21 by the holder pressing portion 51.
