Description

[Detailed description of the invention] (a) Technical field of the invention This invention is a magnetic disk device in which a disk enclosure, a power supply unit, and a package gate are housed in a housing, and is configured to be mounted on a rack using rails. Regarding structure.

(b) Prior Art and Problems A rack mount type magnetic disk device is constructed as shown in FIG. FIG. 1 is a perspective view schematically showing a magnetic disk device. The disk closure 1 houses a recording medium, a spindle mechanism that rotates the recording medium, a magnetic head that performs recording and reproduction on the recording medium, and an actuator mechanism that rotates a swing arm to which the magnetic head is fixed. A plurality of printed boards 3A each having a control circuit are attached to the board. These disk enclosure 1, package gate 3, power supply unit 2 that supplies power, and printed board 3B are housed in a housing 5, and the front of the housing 5 displays ready, alarm, etc. The front panel, which includes the on/off switch, etc., is fixed. When mounting such a magnetic disk device on a rack, the rails 6 fixed to the left and right sides of the housing 5 are attached to the supports of the rack, and by sliding the rails 6, the device can be inserted and removed as shown by arrow A. . In such a device, the casing 5 of the package gate 3 is generally fixed by the second
This is done as shown in the figure. FIG. 2 is a front view showing the fixing structure of a conventional package gate. Since the package gate 3 is attached to the disk enclosure 1 on one side and the rail 6 on the other side at the width point as shown in b, a metal fitting 7 is fixed to the side of the package gate 3, and the mounting The package gate 3 is fixed to the housing 5 by screwing into the hole with a screw 8. When inspecting the back panel 3-1 of the wiring section of the package gate 3 due to a fault, etc., remove the screw 8, pull out the package gate 3 in the direction of arrow C, take it out of the case 5, and check the back panel 3-1. . In this case, back panel 3-1
There is a wiring 9 that connects to other parts, and inspection work must be carried out by holding it in the removed state to prevent short circuits due to contact or the like. After taking out the package gate 3, if you let go of it, it will be in a suspended state by the wiring 9, so you must always hold it, which has the disadvantage of poor workability, and furthermore, the back panel 3 may be attached to other parts. -1 had the problem of causing an accident due to a short circuit if they came into contact with each other.

(c) Purpose of the invention The purpose of the invention is to provide a package gate that can be easily taken out during maintenance and inspection, thereby eliminating the above-mentioned problems.

(d) Structure of the invention The purpose of the invention is to provide such a magnetic disk device with a slideable rod-shaped guide that is locked to the package gate, and one end of the guide is fixed to the side wall via a rotating metal fitting. This is achieved by a magnetic disk device structure characterized in that the other end is provided with a protrusion that serves as a stopper during sliding.

(e) Example of the invention The present invention will be explained in detail below with reference to FIG.
FIG. 3 shows an embodiment of the magnetic disk device structure according to the present invention, in which a and c are front views, and d is a side view. A metal fitting 11 is fixed to the package gate 3, a support plate 12 is fixed to the housing 5, and a guide pin 10 is rotatably locked to the tip of the support plate 12 via a rotation pin 15. has been done.

The metal fitting 11 is fitted onto the guide pin 10 so as to be able to slide along the guide pin 10. Therefore, when the package gate 3 is taken out from the housing 5, the package gate 3 is moved in the direction of arrow C, and the metal fitting 11 is lifted up to a position where it abuts against the flange-shaped stopper 10-1 of the guide pin 10. Next, by rotating the package gate 3 about the rotation pin 15 in the direction of arrow D, the state shown in C can be achieved. By operating in this way, the back panel 3-1 is opened and held while the wiring 9 remains connected, so that maintenance and inspection can be easily performed.

Stopper 16 fixed to package gate 3
If a force is applied in the direction of arrow E when it is released,
The package gate 3 is provided so as to come into contact with a corner portion of the casing 5 to prevent it from moving. Also,
The presser metal fitting 13 is fixed to the housing 5, and the guide pin 1
0, the package gate 3 is provided so that it cannot be rotated in the direction of arrow D when it is housed in the housing 5.

When storing the opened package 3 in the casing 5, remove the contact between the stopper 16 and the corner of the casing 5 and rotate it about the rotation pin 15 in the opposite direction of arrow D, so that the package gate 3 stands upright. This is done by dropping it along the guide pin 10 in this state.

After storage, screw holes 14-1 are provided and screws are secured to the metal fittings 14 fixed to the package gate 3 from the case 5 side, in order to prevent damage caused by vibration during transportation. There is.

(f) Effect of the invention As explained above, the invention provides a metal fitting 11 on the package gate 3 housed in the space of the breadboard, and a guide pin 10 locked by the rotation pin 15 on the housing 5. The package gate 3 can be taken out of the housing 5. As a result, the back panel 3-
When checking 1, it is easy to operate and has the advantage that maintenance and inspection work can be easily performed.
