Description

[Brief explanation of the drawing]

Figure 1 shows an embodiment of this invention, a back view showing the state before loading, Figure 2 a back view showing the completed loading state, and Figure 3 showing the relationship between the cam gear and the swing arm. In the figures shown, a corresponds to Fig. 1, b corresponds to Fig. 2, and Fig. 4 corresponds to Fig. 1.
Figure 5 is a rear view showing the state of the conventional mechanism before loading, Figure 5 is a rear view showing the completed loading state, Figure 6 is a diagram showing the relationship between the cam gear and the swing arm, and a is the same as Figure 4. The corresponding figures and b correspond to FIG. 5. In the figure, 2 is a rotating drum, 3 and 4 are tape pull-out members, 5 and 6 are guide grooves, 15 is a cam gear, 16A is a cam groove, 19 is a disc cam, 20 is a swing arm, and 21 is a swing fulcrum shows.
