Abstract

PURPOSE:To equalize right and left loading posts in pressing force by forming a moving member out of an elastic material, imbedding loading posts in their tips and deforming the moving member accordingly. CONSTITUTION:A driving gear 2 is engaged with gear parts of loading arms 3 and 4 respectively, whereas the loading posts 7 and 8 are imbedded with their supporting shafts in the loading arms 3 and 4 respectively, while the loading arms 3 and 4 are formed of an elastic material. When the driving gear 2 is rotated further from the abutting state of the loading posts 7 and 8 as shown with an alternate long and two short dashes line in the figure against stoppers 13 and 14, the loading arms 3 and 4 are elastically deformed as shown with a continuous line, and by its elastic resiliency, the loading posts 7 and 8 are brought into pressing contact with the stoppers 13 and 14 respectively. By this method, the loading posts can be pressed against the stoppers evenly on right and left by the required pressing force, and moreover the number of parts and the number of assembly manhours can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application Field 2 - The present invention provides a method for guiding a magnetic tape in order to wind the magnetic tape at a predetermined angle around a rotating head drum in a video tape recorder, a digital audio tape recorder, etc. The present invention relates to a tape loading device that moves a loading post to a predetermined position.

2. Description of the Related Art An example of a conventional tape loading device will be described below with reference to the drawings.

FIG. 3 is a plan view showing a conventional tape loading device, and FIG. 4 is a sectional view taken along line AA.

In these figures, 1 is a rotating drum around which the tape is wound. 2 is a drive gear, and 3 and 4 are loading arms that engage with this drive gear. Reference numerals 5 and 6 designate bases movable by loading arms 3 and 4, on which lock posts 9 and 10 are implanted to support loading posts 7 and 8 that engage with the magnetic tape. The bases 5, 6 and the loading arms 3, 4 are connected by pins 11, 12, respectively. 13.14 is loading 3
Me\-/ This is a stopper that restricts the movement of the post. 15 is a magnetic tape, and 16 is a cassette.

The operation of the tape loading device configured as described above will be described below.

First, the position of the loading post indicated by the two-dot chain line in FIG. Move along 1. The magnetic tape 15 is pulled out from the cassette 16 by loading posts 7 and 8 installed on the bases 5 and 6 and wound around the rotating drum 1. Lock posts 9 and 10 abut against stoppers 13 and 14, respectively, and movement of loading post 7.8 is restricted. The lock posts 9 and 10 are attached to the stopper 13.1 by a crimping means (not shown) included in the drive gear 2.
4 to complete the loading. Further, since it is considered impossible for the loading posts 7.8 to come into contact with the stoppers 13.14 at the same time and stop from the standpoint of component accuracy, loading is completed without any of the loading posts being crimped. Therefore, the mechanism to make the crimp force of the left and right loading posts the same is the drive gear 2.
(For example, Japanese Patent Application Laid-Open No. 61-51652)
.

Problems to be Solved by the Invention However, in the above-mentioned configuration, the configuration of the drive gear portion is complicated, and the number of parts is still large, resulting in an increase in the number of assembly steps.

In view of the above problems, the present invention provides a tape loading device that can reduce the number of parts and the number of assembly steps.

Means for Solving the Problems In order to solve the above problems, the tape loading device of the present invention has a moving member made of an elastic material, and a loading post is implanted at the tip of the moving member to deform the moving member. In this way, the loading post is brought into contact with the stopper with a required pressing force.

Function The present invention has the above-mentioned configuration to provide a rotating ponnu 5'\
-/ The number of members that move the loading post is reduced, and the force that presses the loading post against the stopper can also be generated by this moving member.

Embodiment Hereinafter, a tape loading device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing a tape loading device according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line BB.

In these figures, reference numeral 2 denotes a drive gear that engages with gear portions of loading arms 3 and 4, respectively. 8 is a loading post, and the supporting shaft of the loading post is installed in each loading arm 3.4. 1
3.14 is a stopper, 1 is a rotating drum, and these are equivalent to those shown in FIGS. 3 and 4 described above.

The position of the loading post indicated by the two-dot chain line in Fig. 1 is the state in which the loading post is in contact with the stopper, and this is the state from the start of loading except that the loading arms 3 and 4 are respectively rotated by the drive gear 2. The operation at the wheel is the same as that described with reference to FIG. 6 above. When the drive gear 2 is further rotated from this state, the loading arm 3.4 is elastically deformed as shown by the solid line in FIG. 1, and the elastic repulsion forces the loading post 7.8 to the stopper 13. . When the required pressing force is obtained, the rotation of the drive gear 2 is stopped and the loading is completed.

As described above, according to this embodiment, the loading arm is the only part that transmits the moving force to the loading post, and this loading arm also serves as a means for crimping the loading post to the stopper. No means needed.

Effects of the Invention As described above, in the present invention, the moving member that transmits the moving force from the drive means to the loading post is made of an elastic material, and the loading post is implanted at the tip of the moving member, and the moving member is deformed. By configuring the loading post to be crimped onto the collar with the required pressing force, the lock post and base are no longer necessary, reducing the number of parts.

Assembly man-hours can be reduced and manufacturing costs can be lowered.
