Abstract

PURPOSE:To decide a lock state or an unlocked state from the outside by providing a lock member on a substrate containing parts to be locked, extending a projection at the tip of the lock member up to a place near a casing and putting a mark to the outside of the casing. CONSTITUTION:When a boss 11 is rotated by a driver, a lock member 10 is rotated with deflection by an amount equivalent to the degree of eccentricity produced to the boss 11. Then a clamp member 9 is shifted to the position where an optical pickup 1 is clamped. Thus the member 9 is locked. When this lock is released, the boss 11 is rotated reversely to reset the member 10 to its original position. Then the member 9 is reset to its original position owing to its elasticity. While a part of the tip of the boss 11 is extended to form a projection 12, and a mark ''Lock, Free'' is given to the outside of a casing 4 in response to the projection 12. Thus it is possible to decide a lock state or unlocked state from the outside.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is incorporated into a board made by integrally molding a resin onto a metal plate (referred to as non-outsert molding). The locking device of the transport 1" and 5 used in an audio diffuser player is shown. In FIG. A stand, 3 is a guide +11+ that supports the optical pickup 1, 4 is a housing, 5 is a locking material inserted into the long hole 4a of the housing 4 during transportation, 6 arms 4b of the housing 4, movable to 4b The lock material is held in place and has a screw 6a at the tip, and is not γ-keeled.

Regarding the conventional locking device configured as above:
The operation will be explained below.

11): When transporting the item 17 from the outside of the casing 4 in l A.
2 bodies are raised to 4/Go through the long hole 4a and enter Ronokui A'
The optical pickup 10 is fixed by inserting the locking member 5 and fixing it between the optical pickup 1Q and its protruding piece 1a, and the locking member 5 is released by pulling out the locking member 5 from the elongated hole 4a. In addition, in FIG. 1B, a screw 6a is machined at the tip, and the locking material is rotated with a screwdriver etc. from the outside of the housing 4, and the screw 6a is attached to the optical pickup 1.
The optical binoquanograph 1 is turned down by tightening it to a part of the 0. This is done by loosening the locking material 6 and removing it from the optical binoquanog 1 using the force of the via.

However, the conventional configuration as described above has a drawback in that it is difficult to tell whether the device is currently locked or not when viewed from the outside.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a locking device which can determine whether or not it is currently in a locked state using an external device, in order to solve such conventional problems. .

Structure of the Invention The present invention uses a plate made by outsert-molding resin on a metal plate as a space for incorporating parts to be locked, and rotates a cock part which is aratre-molded so that one end becomes a free end. By this, the parts to be locked are configured to be locked, and a protrusion having a needle length is provided at the tip of the lock part near the casing, and a mark is placed on the outside of the casing corresponding to the protrusion. From the outside, it is possible to determine whether or not there is an open status.

DESCRIPTION OF EMBODIMENTS An embodiment of the invention will be described below with reference to FIGS. 21z to 6.

In FIGS. 21-21 to 6, parts having the same functions as those in FIG.

8-piece metal plate board, 9-1 board 8" second out-the-1.
Molded! 2/P member 10 is a lock portion 10 which is also outsert molded on base &8, as shown in Fig. 3A.

As shown in B, the boss 11 on the back side is inserted through the round hole of the board 8.
It is integrated with. The center of the lock part A'A10 and the center of the boss 17 are offset from each other, and the lock door (IS
The boss 11 forms an eccentric shaft. d/Here, the tip of the boss 11 ψ; : F
A part of the protrusion 12 is extended to the vicinity of the casing 4 to form a protrusion 12. Also, in order to extend the protrusion 12 to the rear, a hemispherical shape is attached to the tip of the protrusion 12. 13 small protrusions・
It is a provision. As shown in FIG.
,! The letters I-FreeJ and an arrow 14 are engraved.

The operation of the D7 data device of this embodiment configured as described above will be described below.

From the moss-free state shown in Figure 3A, rotate the boss 11 with a screwdriver. Then lock member 10 & J boss 11.1! :
It rotates by the eccentricity of the
As shown in the figure, move the optical pickup 1 to the sandwiching position. There is a stopper (not shown) on the boss t 1f (+1) of the board 8, and the boss 11 is prevented from rotating further than this Gf installation.The Hikari Pinoquanog 1 is locked in this position. To release the lock, rotate the boss 11 in the opposite direction.Then, the locking member 10 returns to its original position, and the clamping member 9 returns to its original position with its own flexibility. The lock is released. At this time, in case the clamp member 9 does not return completely due to its own elasticity, a part of the clamp member 9 is extended, and the lock part A'io which has been rotated to the released position is Ta:
A return member 9a is attached to a part of the clamp member 9 so as to forcibly return the clamp member 9 at the circumference.

In order to be able to determine whether the current state is a locked state or a free state from the evening+rs++, a part of the tip of the sea urchin boss 11 was removed from the 61st part 11f (not shown). It extends to form a protrusion 12, and as shown in FIG. 6, [LockJ, [F
It is convenient for history if reeJ is engraved. In the example shown in Figure 6, the number 11 and the number 12 are "3 ticks at LockJ, so )Jl.

The material tip pickup 1 is locked (r).
Coming to reeJ is 1, - but 4' is 0. If you do something like this, you can check from the outside whether the JM is locked or not, and F4J will be rejected with 1.

Effects of the Invention Mizumoto IJJ put the protrusion at the tip of the locking part of the outsert on the board 1 which incorporates the parts to be locked, and placed it on the side of the housing J1.
Lock on the outside of the casing at the position corresponding to the protrusion.

A locking device equipped with a mark such as a free arrow, which allows you to judge from the outside whether it is currently locked or free based on the positional relationship between the protrusion and the mark. It is possible to achieve a hit.
