This is a guide hole for 478K.

The above-mentioned pack guide 4] is box-shaped so as to hold a tape lock, and the upper frame 4]A has an elastic protrusion piece 41B in the center. A guide groove 4 is provided on the top surface of the tape pack 40 as shown in FIG.
(JA is provided and the tape notch 40 car) is inserted into the lock guide 41, the elastic protrusion piece 41 is pushed into the guide box 42 by pushing the back guide 4] into the guide box 42
The tape pack is guided forward by engaging guide B with guide *4UA. 40B is a guard installed in the previous issue of Tape Pack 400, and covers the bottom of the tape except when loading.

As shown in FIGS. 6 and 7, the stone side plate 18 is provided with a hook-shaped kite groove blade, which serves to guide the guide bin 51 attached to the side surface of the tape pack guide 4. As shown in Fig. 2, a pair of springs 52A and 52B are hung between the back guide 4] and the kite hox 42, and the pack guide 4]
is always directed downwards.

An arm 53 is interposed between the stone side plate 18 and the guide box 42 as shown in FIGS. engages with the side surface of the kite hox 42. Further, a spring 55 is stretched between the other end of the arm 53 and the fixed pin 540 of the stone side plate 18.

An arm connection is interposed between the left 5m plate 17 and the guide box 42 as shown in FIGS. 8 and 9, and this arm connection is fixed to 11411 & 17 by a fixing bin 57A, and one end thereof is connected to the bin 45A. engaged with X,
do.

Also, a spring guard is provided between the other end of the arm and the fixing pin 57B of the left side plate 17. Also left side plate 1
An arm 59 is interposed below the arm 43 between the kite holder 7 and the kite holder 42, and this arm 59 is fixed to the side plate 17 by a bottle 60A and has a pledge bottle 6 at one end.
0B so that it can come into contact with the lower end 43A of the arm 43. Furthermore, the other end of the arm 59 & Fig. 11 f
a1. A push-up bin 63A is provided which engages with the bin 62 of the push-up member 61 like fbl, and which is freely extended from the base 63B by moving the bin 62 up and down. . This push-up member 6
1 is located in front of the pack guide member, and the 12th o
(When loading the table cover 40 like al, fbl, work to push up the lid 4UB.
, 1, the trap is set in preparation for pulling out the tape.

In the above configuration, the pack guide member 16 is the second cause.
Assuming that the tape pack is in the state before loading as shown in FIGS. 4, 6, and 48, the operation of loading the tape pack will be described.

When the tape pack 40 shown in FIG. 10 is inserted into the pull guide 4 as shown in FIG. 52B into the guide box 42, the tape pack 40 is guided forward. When pushed in further, the pack kite 41 and the guide hook 42 become one body due to the pushing force of the spring i, and the guide bin 5] moves into the guide ff4.
The 50 K bath is guided and dropped as shown in Figures 3, 5, 7 and 9. At this time, the tips of the fan-shaped gears 46A and 46B interposed between the pack guide 41 and the guide box 42 mesh with each other and are reversed as a third factor due to the presence of the fixed pins 48Δ and 48B. The presence of these fan-shaped gears 46A and 46B prevents the pack guide 4 from being dug into five layers when it is pushed.
This prevents the tape pack 40 from being inserted in an oblique direction and prevents damage to +DD.

As a result, the tape pack '40 is positioned at a predetermined position within the pack guide member, and the pair of reel stands 1i4A
, 64L3, tape loading is completed.

When the tape pack 40 is lowered, the arm 5
Since one end of the tape pack 40 is engaged with the guide box 42 from the bin 548K, it is dropped at the same time, but this arm 53 works to control the movement of the tape pack 40 before and after dropping. Fixed bin 54 as shown
With point A as the center, the angles α and β before and after dropping are equal, so that the tape pack 40 is always kept in a horizontal position from front to back. This allows tape pack loading to be performed smoothly.

During the dropping operation, the arm 56 is further rotated counterclockwise (as viewed from the fifth side plate 17) by the pin 45A around the fixed pin 57A as shown in FIG. Since the direction of the projecting portion is opposite to the direction of the projecting portion of the dropping spring group of the right side plate 18, the pushing efforts of both parties cancel each other out, and the tape pack 40 is gradually dropped. Therefore, by providing both spring groups 58, a damper effect can be provided with a simple structure.

Furthermore, the presence of the spring 58 is due to the fact that when the eject operation is performed later, the force direction when pushing the bottle 57C linked to the operation lever in the direction of the arrow to force the arm secretion to rotate clockwise, and the eject direction. LJ:'f also has the effect of being able to reduce the inevitable force on Eniziev with [1 town away].

Furthermore, during the dropping operation, the arm 59 is pushed by the dropped pages of the lower end 43A of the arm 43, as shown in FIG. 9, and the other end of the arm 59 is pushed up, so that The push-up bin 63 of the push-up member 61 extends upward.As a result, the push-up bin 63 is positioned at the front end of the tape pack 400, and therefore moves in the opposite direction to the dropping direction in conjunction with the dropping operation of the tape pack 40. Pushed up, lid 40
Work to open B as shown in Figure 12 ib).

After crucible, the left and right loading blocks 14, 15 pull out the tape from the opening of the tape pack 4υ by the action of the cam gear 5 shown in FIG. 1, and tape loading is performed.

In this case, the pushing-up operation of the push-up bin 63 is performed in conjunction with the falling of the tape pack 40, so the movement stroke dimension in the vertical direction can be saved, and the length of the stroke in the height direction can be particularly reduced. You can get some effect.

When performing the eject-h operation, by pushing the bin 57C linked to the operating lever in the direction of the arrow in Fig. 8, the arm holder rotates clockwise and the bin 45Δ
At the same time as the guide bin 51 is raised, the 21st left and right pair of springs 52A, 52B, ? ) The kite bin 51 returns horizontally along the guide grooves due to the pushing force, so that the tape pack 40 is unroped.

As described above, according to the present invention, a pair of arms are provided on the left stone side plate, and each arm is provided with a spring that is biased in different directions.
When the pack guide and guide box are integrated into the KM, by canceling out the biasing force of the above-mentioned spring,
Since the pack guide is gradually lowered, it can have a tambour effect.
