Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved device for mounting a scanner equipped with a pink-up on a slide rail for accessing the pink-up in the radial direction of a recording medium.

In order to precisely access pink-ups on densely recorded media such as video discs, the scanner must be mounted as precisely as possible on the slide rail.

However, in the conventional device, the scanner to be attached to the slide rail was held by hand and placed on the rail, and the two were screwed together in that state, so there was a possibility that the relative position of the scanner with respect to the rail was not constant.

As a result, the positional relationship of the pickup's smailus with respect to the signal groove is also out of order, resulting in the disadvantage that the best reproduced image cannot be enjoyed.

In the past, one had to hold the scanner with one hand while tightening screws with the other hand, which had the disadvantage of poor work efficiency.

The present invention aims to provide a device that can eliminate the above-mentioned drawbacks.

In other words, the scanner of this device has a recess partitioned by a wall surface that engages each of the three circumferential surfaces of the slide rail, and the slide rail is attached to the recess for positioning and matching. The scanner is held on the rail, and the two can be screwed together in that state.

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is an exploded perspective view of the device, and FIG. 2 is a plan view, front view, left side view, and a sectional view taken along the line x-x' of FIG.

The slide rail 1 has V-shaped grooves 1a on both sides thereof. 1b, and a through hole 1c at its tip.

1d.

On the other hand, the scanner 2 fixed to this slide rail is
A slider base 3, a pickup holder 4 rotatably supported by the slider base, a wiring board 5 fixed to the base, and a cover 6 for covering the end of the rail and the wiring board 5. There is.

The slider base 3 forms a recess A with the cover 6 and the wall surfaces 3a, 3b, 3c to which the three circumferential surfaces of the slide rail, that is, the side surfaces 1e, if, and 1g are attached, respectively. 3c has the through hole 1c
, ld are provided with screw holes 3d and 3e into which headed screws 7a and 7b are inserted.

The slider base 3 has ribs 3f, 3 that support a support shaft 8 for supporting the pick amplifier holder 4.
g, and ribs 3h for fixing the wiring board 5 with screws 9.

Further, the slider base 3 has an engagement hole 31 for receiving the protrusions 6a and 6b provided on the inner surface of the cover 6.
93j.

The pickup holder 4 is provided with a chamber B so that the pink-up 10 can be attached to and removed from the pickup holder 4, and is provided with a heir 11 for controlling the rotation of the pickup holder.

A spring thread groove is provided at the tip of this eldest child so that it can be screwed into a screw hole 3k provided in the slider base 3.

When the two are screwed together, the position of the pickup holder relative to the base is determined.

Output terminals (not shown) of the pink-up 10 are connected to contact pieces 12a and 12b provided on the wiring board 5.

In addition, the above slider base 3, pink amplifier holder 4,
Each cover 6 is molded with resin, and its surface is treated with copper or nickel plating, for example, to provide a shielding effect for the circuit board built into the scanner and to provide an aesthetic appearance.

In the device of the present invention, a pink-up holder 4 is first supported through the slider base 3 by a spindle 8, then a wiring board 5 on which a required circuit component C is attached is fixed to the base 3 with screws 9, and then the slide The recess of the base is attached to the rail 1 for positioning and holding, and in this state, screw the screw 7a.

The assembly is completed by tightening the cover 1b from above the rail, and then fitting the cover 6 onto the base 3 using its elasticity.

As mentioned above, when the slider base is attached to the slide rail, the three wall surfaces constituting the recess of the base are brought into contact with the corresponding side surfaces of the rail, so that the slider base is attached to the rail. Since the base can be reliably positioned and held, and both can be fixed by screws that are tightened from above the rail, the workability is significantly improved and practical.
