Abstract

PURPOSE:To shorten the time required for attachment and detachment by opening one end of one upper rail of the optical head fitting jig. CONSTITUTION:An optical head 1 presses a lower carriage roller 11A against a rail 21A of the fitting jig and an upper carriage roller 11B against a rail 21C at a position 11 to mount the lower carriage roller 11B on a rail 21B. The lower carriage roller 11A and upper carriage roller 11B of the optical head 1 are moved to the fixation position of the optical head 1 while pressed against the rails 21A and 21B of the fitting jig. At this time, the preload carriage roller 26 of a pre-load arm 25 is pressed by the rail 28 whose one end is open to determine the position of the optical head 1 about the rails 21A, 21B, 21C, and 28. Consequently, the fitting does not require a long time.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an optical head mounting jig.

[Conventional technology]

A conventional optical head mounting jig is shown in FIGS. 2(a) and 2(b).

In the optical head 1, the lower carriage rollers 11A and 11B are placed on the rails 21A and 21B of the mounting jig, the upper carriage roller 11B is pressed against the rail 21C, and then the rail 21D is placed in the guide groove 22 of the handling jig. Both ends of the rail 2LD are fixed to the mounting jig using the plate 23 and screws 24.

As a result, the rail 2LD is connected to the pressurized arm 2 of the optical head 1.
The pressurized carriage roller 26 of No. 5 is pressed against the four rails 11A.

11B, IIC, and IID.

In this state, the optical head 1 is guided by the four rails and can move on the rails, so the stop bar lever 30
The rail is fixed to prevent it from moving.

[Problem to be solved by the invention]

As described above, the optical head is mounted and fixed on the optical head mounting jig, but since both ends of the rail are fixed by a plate that presses the rail and screws, there is a drawback that it takes time to install the optical head.

[Means to solve the problem]

The optical head mounting jig of the present invention is an optical head mounting jig for testing an optical head that integrates a case constituting the optical head and a carriage on which the optical head is moved. The optical head has two rails on which the optical head is placed, and at least one of the two rails that presses down the carriage bearing at the top of the optical head, with one side open.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIGS. 1(a) and 1(b) are a top view and an AA arrow view showing an embodiment of the present invention.

The optical head 1 is 1. Lower carriage roller 11 at position i
A onto the rail 2rA of the mounting jig, press the upper carriage roller 11B against the rail 21C, and place the lower carriage roller 11B on the rail 21B.

Install the lower carriage roller 11A and upper carriage roller 11B of the optical head 1 on the rails 21A and 21 of the mounting jig.
While pressing against C, move to the fixed position of the optical head 1.

At this time, the pressurized carriage cola 26 of the pressurized arm 25
are held down by a rail 28 with one end open, and the rails 21A, 21B, 2IC, 2 of the optical head 1
The place W for 8 is determined.

Next, the stopper lever 30 is used to fix the optical rack l so that it does not move on the rail.

〔Effect of the invention〕

As explained above, the present invention allows the optical head to be easily mounted on the rail without attaching or removing the rail by opening one end of one of the upper rails of the optical head mounting jig. It can be positioned and fixed in place, which is effective in reducing the time required for installation and removal.

The same effect can be obtained by similarly opening one end of the two upper rails of the optical head mounting jig.
