Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a magnetic head transport device, and particularly to a magnetic head transport device for positioning a magnetic head member on a soft storage medium such as a flexible disk.

[Prior art]

A conventional device of this kind is constructed as shown in FIGS. 1 to 5, in which numeral 1 denotes a conveyance member that is conveyed by an actuator (not shown) and positioned at a predetermined position on a flexible disk (not shown). 2 and a holding pedestal part 3. A lower magnetic head member 5 is fixed to a holding piece 4 provided in the opening 2, and the lower magnetic head member 5 has a head cover 8 having a window 7 through which the magnetic head 6 faces.
covered with. A plate-shaped elastic member 12 protruding from the rear edge of the movable member 10 is fixed to the holding base portion 3, and the movable member 10 can be rotated by a certain angle in the vertical direction. The upper magnetic head member 1 is attached to the movable member 10.
1 is positioned so as to face the lower magnetic head member 5, and this head member 11 is connected to the band-shaped elastic bodies 13, 1.
3, it is held elastically. A pin 14 protrudes from approximately the center of the movable member 10, and the lower end of a coil spring 15 is fitted onto this pin 14, so that the movable member 10 is constantly pressed downward by this spring 15. The upper end of the coil spring 15 is held by a holding member 17 that is fixed to the holding pedestal 3 side and has a coil spring fixing piece 16 that projects upward from the movable member 10 .
An arm 18 protrudes from the side of the movable member 10, and when the tip of the arm 18 is pushed up by an operating piece of a solenoid (not shown), the movable member 10
moves upward against the coil spring 15. By turning off the current to the solenoid, the movable member 10 is moved downward by the spring 15 while causing the plate-like elastic agent 12 to bend, and the magnetic head member 11 is brought into contact with a flexible disk (not shown) with a constant pressure. .
On the other hand, the magnetic head member 5 also contacts the lower surface of the flexible disk with a constant pressure due to the reaction force of the pressing force of the magnetic head member 11. In this state, magnetic signals are read and written between the magnetic head members 5, 11 and the flexible disk.

As shown in FIGS. 2 to 5, lead wires 32 and 33 are connected to the signal wires 30 and 31 led out from the lower and upper magnetic head members 5 and 11 by solder. , 33 are connected to a connector 34. The lead wire 32 soldered to the signal line 30 of the lower magnetic head member 5 is pressed against the rear surface 35 side of the conveying member 1 by a presser plate spring 34 fixed with a screw 33, and further
After being fitted into a recess 37 provided on the end surface 36 on the side of the holding pedestal and for regulating displacement,
It is drawn out to the front side of the conveyance member 1, and is pulled out to the outside together with the lead wire 33 on the front side.

However, according to such a configuration, when the lead wire 32 is pulled out toward the surface side of the conveying member 1 through the recess 37, tension in the direction of arrow F is applied, so that the lead wire 32 and the signal wire 30 are not connected. There is a drawback that the lead wire 32 may come off or be damaged from the soldered portion where the mechanical connection is weak.

The present invention was developed to eliminate the above-mentioned drawbacks, and in order to prevent the lead wire from shifting, a boss is planted in the front of the recess provided on the end face of the conveying member, and the lead wire bypasses the boss. This prevents tension from being applied to the soldered portion of the lead wire due to the frictional force between the detour portion of the lead wire and the boss.

6 to 8 are simplified configuration diagrams showing one embodiment of the magnetic head transfer device according to the present invention, and the same reference numerals are used for the same or corresponding parts as in FIGS. 1 to 5. In each figure, the recess 37 provided in the rear end surface 36 of the conveying member 1 is connected to the lead wire 32.
A boss 40 is placed immediately before the recess 37 on the magnetic head member 5 side.
will be planted. The lead wire 320 soldered to the signal wire 30 of the magnetic head member 5 is given a slack 41 in the lateral direction, then makes a detour 42 along the peripheral wall of the boss 40 and is then fitted into the recess 37. In this case, by providing a cutout 43 in the rising frame 38 on the back side and fitting the lead wire 320 into the cutout 43, the positional shift of the lead wire 320 can be restricted. Reference numeral 44 denotes a presser plate spring fixed to the back side of the conveying member 1 with a screw 45, and a presser plate spring 46 extending in a direction that longitudinally traverses the conveying member 1,
It has an L-shape and a presser piece 47 extending toward the rear end. The signal line 30 is held by the holding piece 46.
Hold down the lead wire just after it is connected to. Presser piece 4
7 abuts against the end surface of the boss 40 to prevent the detour portion 42 of the lead wire from coming off the boss 40.

According to the above configuration, when pulling out the lead wire 320 to the surface side of the conveying member 1 via the recess 37,
The detour portion 42 comes into pressure contact with the peripheral wall of the boss 40, and the friction generated here restricts its movement even if the lead wire 320 is pulled, so no tension is applied to the soldered portion and the lead wire 320 is detached. or
This can prevent the soldered parts from being damaged. Also,
The holding plate spring 44 prevents the detour portion 42 of the lead wire 320 from coming off the boss 40.

As explained above, according to the present invention, a boss is planted in the front part of the recess provided on the end face of the conveying member in order to restrict the positional shift of the lead wire, and the lead wire detours along the peripheral wall of the boss. When the lead wire is pulled out, the friction between the detour part of the lead wire and the boss prevents tension from being applied to the soldered part of the lead wire. This prevents the lead wire from coming off and being damaged.
