The present invention relates to a pole base crimping device of a camcorder, and more particularly, a spring is mounted on a tip of a folate slider of a pole base and a tip of a support part which guides and contacts a tape to a drum of a camcorder. It keeps the pressing force on the pole base until it is kept.

Conventionally, as shown in FIG. 1, one side of the deck 1 is provided with a cam gear 2 which is rotated by receiving power from a motor (not shown), and the cam gear 2 has a cam groove 3. The lever 5 is hinged so as to guide the guide pin 6 of the lever 5, which is formed at the front end and has the sector gear 4 formed thereon.

On the other hand, guide grooves 8 for guiding the pole base are formed on both sides of the deck 1 on which the drum 7 is installed, respectively, and the inclined poles 9a for guiding the tape and guides on the guide grooves 8 on both sides. A pole base 9 provided with poles 9b is installed to be guided, and each pole base 9 has a pair of gear members installed in engagement with the deck 1 inside the guide groove 8. 10), it was connected to the lever 11 and the link 12 fixedly installed at (10a).

Further, the sector gear portion 4 of the lever 5 is engaged with the gear member 10 on one side, so that the cam gear 2 rotates by the rotational force of the motor, and the cam gear 2 is the cam arc 3. The lever 5 having the guide pin 6 guided in the center rotates about the hinge portion 5a, thereby allowing the gear members 10 and 10a on both sides to rotate. And the link 12 is to operate, the pole base 9 installed at the tip of the link 12 is configured to be guided and moved to the guide groove (8).

However, as shown in FIG. 1, various components for driving the installed pole base occupy much more installation space than necessary, which is a deterrent to deck miniaturization, which is contrary to the recent miniaturization trend. There is a problem in that the light force, especially when the pole base loading or after the completion of loading can not continue to maintain the pressing force.

This invention is proposed to solve the above problems, and the purpose of this invention is to reduce the size of the camcorder deck to reduce the size of the product, as well as to continue the loading and post-loading of the pole base. The present invention provides a pole base crimping device for a camcorder that can maintain a compressive force on a pole base to improve tape driving capability.

A feature of this invention for achieving the above object is that the pole base is driven by the cam groove of the second cam gear which rotates in response to the power of the loading motor from the main deck of the camcorder to drive the pole base. There is a pair of support members provided with a support pin to compress the spring and the pole base crimping device of the camcorder configured to each spring is elastically installed at the front end of the plate slider.

Hereinafter, a temporary example of the eye will be described in detail with reference to the accompanying drawings.

2 is a plan view showing the structure and operating state of the pole base driving apparatus according to the present invention, the main deck 27 of the deck (100) separated into the main deck 27 and the sub deck 28 of the camcorder on the center The drum 26 is installed at a predetermined position of the pair, and a pair of upper guide rails 32 having a loading groove 31 are provided on both upper sides thereof, and the sub operated on the main deck 27 before and after. A pair of lower guide rails 33 having a loading groove 34 to which the upper guide rail 32 is connected are installed at both front ends of the deck 28.

On one side of the drum 26 on the main deck 27, there is a loading motor 20 and a driving gear 21, a first gear 22, a first cam gear 23, a second gear 24, which are power transmission devices. -The second cam gear 25 is engaged in order, and the second cam gear 25 is formed with a cam groove 25a.

In addition, the cam cam 25a of the second cam gear 25 is guided between the second cam gear 25 on the main deck 27 on which the second cam gear 25 is installed and the bottom surface of the main deck 27. Guide pins (35) and guides (36a) guided to guide holes (28a) of the sub-deck (28) in the central portion, and the support pin (37b) by installing the spring 37a on both sides of the front end portion to maintain elasticity The plate member 38 hingedly coupled to the supporting member 37 provided therein is installed to be capable of lifting and lowering.

In addition, a pair of loading arms 39 corresponding to the support pins 37b on the bottom of the fold deck 28 and provided with support grooves 39a are hinged, and the upper and lower ends of the loading arms 39 are hingedly coupled to each other. The pole base 40 guided by the loading grooves 31 and 34 of the guide rails 32 and 33 is coupled to the first and second links 41 and 42 to be installed.

The effect of this design constructed as described is as follows.

As shown in FIG. 2, drive gears 21-first gear 22-first cam gear 23, in which rotational forces of the driving motor 20 driven on the main deck 27 of the camcorder are respectively engaged with each other. -Second gear 24-when power is transmitted in the order of second cam gear 25, the cam cam 25a guided to the second cam gear 25 as this second cam gear 25 rotates. The plate slider 38 having the guide pin 35 to be guided is moved.

As the platen slider 38 moves, the support arms 39a pivot on the loading arms 39 on both sides of the plate slider 38 supported by the support pins 37b at both ends of the plate slider 38, such as "A". The pole base 40, which is installed as a first link 41 and a second link 42 at the distal end of the two loading arms 39, respectively, has an upper guide rail 32 in the loading groove 34 of the lower guide rail 33. It is imagined that it is loaded into the loading groove 31 of).

In this state, since the rotational force of the second cam gear 25 which continues to rotate continues to lower the plate slider 38, the loading arm 39 tries to rotate further in the "A" direction, and the pole base 40 To continue to move to the loading groove 31 of the upper guide rail 32, the pole groove 40 is completely moved to the loading groove 31 is no longer movable.

At this time, the plate slider 38 and the loading arm 39 to be continuously moved are hinged portion 39b having the loading arm 39 hinged to the bottom of the sub deck 28 and the support groove 39a of the loading arm 39. The pair of support members 37 which are hinged elastically on both ends of the plate slider 38 by the interaction of the support pins 37b supported by the two sides are rotated by a predetermined angle by the elasticity of the spring 37a. Each pole base 40 installed at the distal end of both loading arms 39 is elastically applied to the loading groove 31 of the upper guide rail 32 so that the tape is loaded and elastically applied to the tape tension during driving. It becomes possible to cope.

As described above, by using the pole base compression device of the camcorder according to the present invention, it is possible to flexibly cope with the tape tension during driving by maintaining the pressing force on the pole base during loading of the pole base and after completion of loading. It is a very useful design with many advantages, such as smooth operation.
