Abstract

PURPOSE:To attain a compact type driving system unit by providing an ultrasonic vibration rail to a rail part where a tape loading post of a VTR is driven. CONSTITUTION:An ultrasonic vibration rail 8 is provided to a rail part 6 where a loading post 2 of a base plate is driven. The pedestal 1 set on the rail 8 can move in any direction by the ultrasonic vibrations produced by the rail 8. Thus a tape is wound round a rotary magnetic head drum by the post 2. As a result, a loading mechanism part is miniaturized and a compact tape driving system unit is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape loading device that is effective in reducing the size and weight of the tape loading mechanism and the compactness of the tape running system unit.

Conventional tape loading devices wind the tape around a rotating magnetic head drum using a loading post, and conventional devices use a gear mechanism, resulting in a very complex mechanism. It became.

The configuration of a conventional tape loading device will be described below with reference to the drawings.

FIG. 3 is a schematic view of the mechanical part of a conventional loading device as seen from the back side of the base plate, and FIG. 4 is a partial perspective view of the loading post part as seen from the front side of the base plate. In the figure, 1 is a pedestal for guiding a loading post 2, and is connected to a gear 3. The gear 3 operates in the direction shown by the arrow 5 as the drive gear 4 rotates, thereby causing the pedestal 1 to move in the direction of the arrow 7 along the rails on the base plate (not shown).

Problems to be Solved by the Invention However, when using the above-mentioned conventional loading device, it is necessary to install the loading mechanism shown in FIG. A motor (not shown) is also required,
There is a problem in that the mechanical parts become very complicated, and the volume and weight occupied by the above-mentioned mechanical parts in the traveling system unit become large.

The present invention is intended to solve these conventional problems.
The object of the present invention is to provide an excellent tape loading device in which the loading mechanism is made smaller and lighter, and the traveling system unit is made more compact.

Means for Solving the Problems In order to achieve the above object, the present invention provides an ultrasonic vibration rail in the rail portion that drives the loading post of the pace plate.

Therefore, according to the present invention, since the ultrasonic vibration beam is provided on the rail portion of the base plate, it is possible to eliminate the gears and motor for driving the loading post, which were located on the back side of the conventional base plate, and the loading mechanism can be easily operated. It can be made smaller and lighter, and the travel system unit can be made more compact.

EXAMPLE Hereinafter, an example of the present invention will be described using FIGS. 1 and 2.
The same parts as in the conventional example will be described with the same numbers. In the figure, reference numeral 8 indicates an ultrasonic vibration ray/L/8, which is located at the same location as the rail portion 6 of the pace plate (not shown), and a pedestal 1 is placed on the ultrasonic vibration ray/L/8. be done. The pedestal 1 can move on the ultrasonic vibration generated in the ultrasonic vibration beam /L/8 in any direction shown by the arrow 7, so that the tape can be transferred to the rotating magnetic head drum by the loading post 2. (not shown).

In this way, according to the above embodiment, since the ultrasonic vibration rail 1L/8 is provided at the same location as the rail portion 6 of the pace plate, there is no need for a complicated mechanism such as a drive gear or a motor, and it is extremely simple. This mechanism allows the tape to be loaded onto a rotating magnetic head drum.

Effects of the Invention As is clear from the above embodiments, the present invention provides an ultrasonic vibration rail in the rail section, so the loading mechanism can be downsized, and the traveling system unit can be downsized. It has the effect of becoming
