Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video tape recorder with a simplified tape loading mechanism.

Video tape recorder (hereinafter referred to as VTR)
In this case, a loading mechanism is required to pull out the tape stored in the cassette pack, wrap it around a rotating cylinder equipped with a head, and run the tape.

In the conventional loading mechanism, the tape is pulled out from within a cassette pack set opposite to a rotating cylinder, with both ends supported by a pair of loading posts consisting of a supply side loading post and a take-up side loading post. The tape is wound around the rotating cylinder by moving the pair of rotating posts to predetermined positions so as to symmetrically surround the rotating cylinder from the left and right sides.

In order to move the pair of loading posts symmetrically from within the cassette pack to predetermined positions around the rotating cylinder, the loading posts on the supply side and the loading post on the take-up side, each consisting of a vertical post and an inclined post, are required. By providing blocks that support the loading post and providing separate gear mechanisms to these blocks, each of the gear mechanisms is separately driven to a predetermined position via the loading plate to which driving force is transmitted from the drive source. The loading post is positioned.

However, as described above, providing a gear mechanism for each of the pair of loading posts on the supply side and the winding side causes problems in that the structure is complicated and the size is unavoidable. There is also the problem that adjustment is difficult and requires a lot of time.

The present invention has been made in response to the above-mentioned problems.One side of a pair of loading posts consisting of a vertical post and an inclined post is fixed in a cassette pack for storing tape, and the other side is fixed to a cassette pack for storing a tape. To provide a video tape recorder configured such that a loading post is movable around a rotating cylinder, and tape loading is performed by moving only the loading post on the other side to a predetermined position, thereby eliminating the conventional drawbacks. The purpose is to Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing a video tape recorder according to an embodiment of the present invention, in which 1 is a cassette pack;
2 is a tape, 3 is a supply side reel, 4 is a take-up side reel, 5 is a supply side loading post consisting of a vertical post 5a and an inclined post 5b, and 6 is a take-up side loading post consisting of a vertical post 6a and an inclined post 6b. Post, 7 is a rotating cylinder, 8 is a loading gear, 9 is a loading plate, 10
11 is a combination head, 12 is a capstan, and 13 is a pinch roller.

In the above process, before loading the tape 2, the tape 2 is stored in the cassette pack 1, and the supply side loading posts 5, 5a, 5b of the pair of loading posts are placed in the cassette pack 1, for example, with the cassette pack. A cassette pack 1, which is either integrally formed or formed from a separate member and fixedly provided, is prepared and loaded into a predetermined position of the VTR. At the same time, when the operation switch is turned on, a drive source (not shown) is operated, and its driving force operates the loading plate 9 via the loading gear 8 to position the video head at a 90° position relative to the cassette pack 1. The loading post 6 on the winding side is rotated approximately 15 degrees counterclockwise and the tape 2 is attached to the rotating cylinder 7 from inside the cassette pack 1.
With the tape 2 pulled out, rotate it counterclockwise to wrap the tape 2 around the rotating cylinder 7. When tape loading is completed by positioning the winding side loading post 6 at a predetermined position in this way, it is detected by the detection device and then the full width erasing head 10, the combination head 11,
The capstan 12 and the pinch roller 13 enter the cassette pack 1, and the tape 2 begins to run.

FIG. 2 is a schematic top view showing the above operating state.

According to the above configuration, one side of the pair of loading posts is fixedly provided within the cassette pack 1, and only the other side is provided in a movable state by a gear mechanism etc. during tape loading. This simplifies the loading mechanism since it only needs to be moved to a predetermined position.

Therefore, the loading mechanism can be made smaller, thinner, and lighter, and furthermore, it can be easily adjusted, so that time can be saved.

Claims (1)

[Claims] 1. In a videotape recorder configured to move the tape to a predetermined position and wrap it around a rotating cylinder while supporting both ends of the tape by using a pair of loading posts consisting of a vertical post and an inclined post, the above-mentioned pair of loading posts are used. One side of the loading post is fixed in a cassette pack for storing tape, and the other side is movable around the rotating cylinder, and only the loading post on the other side is placed at a predetermined position around the rotating cylinder. A video tape recorder characterized in that the tape is wound around a rotating cylinder by moving the tape around the rotating cylinder.
