In the tape printing apparatus 1 and tape drum 30 of above-mentioned explanation, in the situation that tape drum 30 being installed on to box installation portion 8, uprightly be arranged at three leading axles (band driving shaft 100, leading axle 120, asessory shaft 110) of box installation portion 8 and three bullports (roller supported hole 64, bullport 47, the 1st are with supported hole 65) and an insertion section 39 guiding that a retainer 74 is located at respectively tape drum 30, tape drum 30 is installed in the appropriate location of box installation portion 8.

Herein, in present embodiment, tape drum 30 is with respect to the handling mode of box installation portion 8, with reference to Figure 19～Figure 26, describe.In Figure 19, Figure 20 and Figure 23, the right flank of tape drum 30 is shown, but for ease of understanding, with imaginary line (double dot dash line), the hole portion relevant with the handling of tape drum 30 etc. is shown.In addition, the summary section while showing from right side observation box installation portion 8, but for ease of understanding, only illustrate the axial region relevant with the handling of tape drum 30.But, in Figure 23, bullport 47 and near cutaway view in right side view thereof are represented.In addition, in Figure 21, Figure 22 and Figure 24, the front of tape drum 30 is shown, but for ease of understanding, the end of the left and right of an insertion section 39 of use imaginary line (double dot dash line) expression tape drum 30.In addition, in Figure 21, Figure 22 and Figure 24, the diagram of thermal head 10 is omitted.

First, the height relationships of each member that is uprightly arranged at box installation portion 8 is described.In retainer 74, band driving shaft 100, colour band wireline reel 95, asessory shaft 110, leading axle 120, the axial length of three leading axles (band driving shaft 100, asessory shaft 110, leading axle 120) about equally.And, with each axial length of driving shaft 100, asessory shaft 110 and leading axle 120, be greater than the axial length of colour band wireline reel 95 and the longitudinal size of a retainer 74.Therefore, in retainer 74, band driving shaft 100, colour band wireline reel 95, asessory shaft 110, height and position with the upper end of driving shaft 100 and asessory shaft 110 is maximum, and then the height and position of the upper end of a retainer 74 is larger, and the height and position of the upper end of colour band wireline reel 95 is minimum.But, the height and position of the upper end of colour band wireline reel 95 be fixed on a retainer 74 thermal head 10 upper end height and position about equally.

Leading axle 120 is uprightly arranged at support portion, angle 812 as previously mentioned.And the height and position of the upper end of leading axle 120 is greater than a retainer 74, with the height and position of the upper end of any in driving shaft 100, colour band wireline reel 95, asessory shaft 110.

As shown in figure 19, user is installed on tape drum 30 in the situation of box installation portion 8, make roller supported hole 64, the 1st with supported hole 65, bullport 47 respectively with respect to roughly consistent with driving shaft 100, asessory shaft 110, the relative position of leading axle 120 on top view, as previously mentioned upper plate 305 and base plate 306 are maintained in to approximate horizontal and vertically embed.Make tape drum 30 downwards when box installation portion 8 moves, each upper end with driving shaft 100, asessory shaft 110, leading axle 120 roughly side by side enters respectively peristome 64B, 65B, the 47B arranging on the base plate 306 of tape drum 30 as shown in figure 20.On the other hand, owing to being positioned at the state of the below of base plate 306 in a retainer 74 and colour band wireline reel 95 upper end separately, so do not enter the inside of tape drum 30.

If from the state shown in Figure 20, tape drum 30 is further moved downwards, be with driving shaft 100, asessory shaft 110, leading axle 120 via peristome 64B, 65B, 47B, from below, to insert axis hole 46D, 65C, 47C respectively.Inside at axis hole 46D, 65C, 47C, insert respectively with the movement to Zhou Fangxiang by the inner wall limit of each axis hole 46D, 65C, 47C of driving shaft 100, asessory shaft 110, leading axle 120, become the state that can slide along its upright setting party to (that is, above-below direction).In other words, tape drum 30, and is also moved downwards to guiding by the upright setting party with driving shaft 100, asessory shaft 110, leading axle 120 along inserting axis hole 46D, 65C, 47C respectively under the effect of deadweight.

In addition, the upper ora terminalis with driving shaft 100, asessory shaft 110, leading axle 120 forms the conical by its shape diminishing towards its upper end diameter of axle.Therefore, though with respect to roller supported hole 64, the 1st with the skew producing in supported hole 65, the relative position of bullport 47 on top view a little, also can suitable and successfully make to be with driving shaft 100, asessory shaft 110, leading axle 120 to insert.In addition, because the diameter of axle with driving shaft 100 is slightly less than the A/F of being with driven roller 46 (axis hole 46D), even therefore in the interior plan-position with driven roller 46 of roller supported hole 64 because vibration and inclination etc. change a little, also can successfully make to be with driving shaft 100 to insert.

And, as previously mentioned, the A/F of bullport 47 is larger than the diameter of axle of the leading section of leading axle 120 (aforesaid path axial region 120B), particularly with from Xiang Dao left back, right front to A/F compare, from Xiang Dao right back, left front to A/F larger.Therefore,, when the installation of tape drum 30, even be offset a little with respect to the relative position of the bullport 47 on the top view of leading axle 120, also can make leading axle 120 insert bullport 47.Thus, for whole three leading axles of being located at box installation portion 8, do not need each corresponding hole portion of tape drum 30 correctly to locate, therefore when the installation of tape drum 30, alleviated user's burden.In addition, when the manufacture of tape drum 30, in order to make the dimension width of roller supported hole 64 and bullport 47 with in full accord with the dimension width of driving shaft 100 and leading axle 120, to the exigent dimensional accuracy of operator.About this point, loosening by forming in bullport 47, can allow the dimensional accuracy that forms bullport 47 to have error a little, the burden during manufacture that therefore also can alleviate tape drum 30.

In addition, colour band wireline reel 95 inserts axis hole 44C from below via peristome 68B.Because the diameter of axle of the A/F colorimetric tape wrapping axle 95 of colour band winding reel 44 (axis hole 44C) is large, therefore at the interior colour band wireline reel 95 of colour band winding reel 44, becoming can be at the loosening insertion state of Zhou Fangxiang top offset.

On the other hand, from the position shown in Figure 20, follow tape drum 30 to be guided downwards, as shown in figure 21, a retainer 74 is from insert head insertion section, below 39.The 1st distance A 1 (with reference to Figure 12 and Figure 13) is little than the distance of the left and right directions of an insertion section 39 for the distance of the left and right directions on the top of retainer 74.Therefore,, even if produce skew a little in the relative position on the top view of tape drum 30 with respect to a retainer 74, a retainer 74 also can not tangle the end of the left and right of an insertion section 39, but successfully inserts.

When tape drum 30 further moves, as shown in figure 22, be located at the stage portion 741 insert head insertion sections 39 of a retainer 74 downwards.Thus, the end of the left and right directions of an insertion section 39 is included stage portion 741 in 74 guiding of an interior retainer, by the 39 suitable positions of guiding, an insertion section.

When tape drum 30 is moved downwards along a retainer 74, band driving shaft 100, asessory shaft 110, leading axle 120, as shown in figure 23, the alignment pin 103 being uprightly arranged on support portion, angle 812 contacts with the roof in pin-and-hole 63.Meanwhile, although not shown in Figure 23, the alignment pin 102 being uprightly arranged on support portion, angle 812 inserts pin-and-hole 62, and the upper end of alignment pin 102 contacts with the roof in pin-and-hole 62.In addition, as shown in Figure 23 and Figure 24, box support portion 742 contacts and is positioned with downside planar portions 392B.That is the height and position that, is installed on the tape drum 30 of box installation portion 8 is defined as the height and position supporting by alignment pin 102,103, box support portion 742 etc.

In addition, the base end side of leading axle 120 (aforesaid large footpath axial region 120A) is directed and embed bullport 47 (axis hole 47C) along tapered portion 120C.As previously mentioned, about equally, therefore large footpath axial region 120A by closely engaging, limits the displacement to Zhou Fangxiang of leading axle 120 from the fore-and-aft direction of bullport 47 for the large diameter of axle of footpath axial region 120A and the A/F of bullport 47.In addition, alignment pin 102,103 is engaged in the inside of pin-and-hole 62,63 respectively, the displacement to Zhou Fangxiang of restriction alignment pin 102,103.That is the plan-position that, is installed on the tape drum 30 of box installation portion 8 is defined as by the plan-position of leading axle 120 and alignment pin 102,103 engagings.

Like this, in present embodiment, tape drum 30 is guided until the appropriate location of box installation portion 8 by three leading axles (band driving shaft 100, asessory shaft 110, leading axle 120), a retainer 74.And the directed axle 120 of tape drum 30 and alignment pin 102 are positioned suitable plan-position, and are positioned suitable height and position by box support portion 742, alignment pin 102,103 etc.And tape drum 30 is located under the state of appropriate location, as shown in figure 25, at cam member 100A and the snap over rib 46F with driven roller 46 of the base end side setting with driving shaft 100, suitably mesh.In addition, as shown in figure 26, be located at the cam member 95A of colour band wireline reel 95 and the snap over rib 44D of colour band winding reel 44 suitably meshes.In addition, the thermal head 10 of being located at a retainer 74 is configured in the suitable print position of an insertion section 39.That is, becoming tape printing apparatus 1 can carry out aptly to the state of the printing of band.

In addition,, in the situation that tape drum 30 is pulled down from box installation portion 8, for example user uses the sidewall of the left and right of fingerhold tape drum 30, and tape drum 30 is extracted upward from box installation portion 8 simultaneously.Now, in tape drum 30, by a retainer 74 and three leading axles (band driving shaft 100, asessory shaft 110, leading axle 120), guide along the vertical direction tape drum 30.Therefore,, the process that tape drum 30 is pulled down from box installation portion 8, prevented run-off the straight in tape drum 30 and tangled the possibility of the inwall etc. of box installation portion 8.

Carry out as mentioned above the handling to box installation portion 8 of the tape drum 30 of present embodiment.In existing tape drum, the length of the left and right directions of an insertion section 39 i.e. the 1st distance A 1 is that the right part of from the beginning insertion section 39 is until the length of the right part of tape drum 30 is that the 2nd distance A is below 2.With respect to this, in present embodiment, as shown in FIG. 12 and 13, the 1st distance A 1 is greater than the 2nd distance A 2.In this situation, the center of gravity of tape drum 30 is easily positioned at the 1st region 331.In present embodiment, as previously mentioned, the center of gravity of the tape drum 30 of stacked, the receiver formula shown in Fig. 4～Fig. 7, heat-sensitive type is positioned at the 1st region 331.That is, the left and right directions Shang center of an insertion section 39 approaches the center of gravity on the left and right directions of tape drum 30.That is, weight balancing is good.Therefore,, in the situation that tape drum 30 being installed on to box installation portion 8, during by a retainer 74 guiding, tape drum 30 possibility that direction tilts is to the left and right lower.Therefore, tape drum 30 is disposed at box installation portion 8 aptly.Therefore, band etc. is transmitted aptly, and printing precision is improved.
