An electronic device in which a door that can be opened and closed is provided on a part of the surface of a housing that is provided with a stopper fitting on the frame of the housing inside the door, and a hanging tool that engages with the stopper. A shelf plate is provided, and when a test or the like is required, a hanging member of the shelf plate is engaged with a stopper of the frame to form a shelf, and the shelf is removed during normal operation.

[Industrial application field]

The present invention relates to an electronic device having an electronic circuit unit and the like housed inside a housing.

A power supply device, a printed board unit, an electronic circuit unit such as a magnetic disk, and the like are mounted in the housing of the electronic computer.

The operation inspection of the electronic circuit unit is required at the time of assembling the device, and the inspection is also required at the time of repair and inspection.

[Conventional technology]

As shown in FIG. 3, for example, a conventional electronic device accommodates an electronic circuit unit such as a power supply device 2, a printed board unit 3 and a recording device 6 inside a housing 1.

Conventionally, an inspection device such as a tester or an analyzer (hereinafter collectively referred to as a tester) is directly placed on the floor with the door 7 opened during the inspection, or a dedicated stand 5 as shown in FIG. 3 is prepared. The tester 4 was placed on it for inspection work.

[Problems to be solved by the device]

However, when the tester 4 is placed on the floor during the inspection, not only the operability of the tester 4 is deteriorated, but also the tester cord does not reach the upper part of the device.

When a dedicated table 5 for mounting the tester 4 is used as shown in FIG. 3, the dedicated table 5 may be transported to a place where it is used.
There is a problem that the dedicated table 5 takes up a space, and the electronic circuit unit cannot be efficiently inspected.

Therefore, an object of the present invention is to provide an electronic device for eliminating the above-mentioned drawbacks and improving the inspection work.

[Means for Solving the Problems]

As shown in FIG. 1, the above-mentioned problem is in an electronic device in which an electronic circuit unit is housed in a housing 1 with an opening / closing door, and at least the upper and lower sides of a frame 8 on the opening surface of the housing 1 inside the door. Stoppers 9 and 10 provided at three locations and stoppers 9,
And a detachable shelf plate 13 having suspenders 11 and 12 that removably engage with 10, and if necessary, suspenders 11 and 12 are engaged with the fasteners 9 and 10 to form a shelf. It is solved by the electronic device of the present invention, which is removed during normal operation.

[Action]

That is, with the door 7 of the housing open, the frame 8 of the housing 1
The suspending tool 11 provided on the shelf board 13 is inserted into the hole of the fastener 10 provided in the middle stage to attach the shelf board 13 to the frame 8, and further, the chain provided on the opposite side of the suspending tool 11 of the shelf board 13 By hooking the suspending tool 12 via 15 into the groove of the stopper 9 of the frame 8, the shelf plate 13 becomes a shelf formed so as to be perpendicular to the surface of the frame 8.

By mounting the tester 4 on this shelf, the inspection work of the electronic circuit unit and the like can be easily performed. Since not only the tester but also tools and the like can be placed on the shelves, it is possible to contribute to improving the workability of the device assembly.

〔Example〕

FIG. 1 is a diagram for explaining an embodiment of the present invention, showing a state in which a door is opened, and FIGS. 2 (a) and 2 (b) are for explaining the engagement of the suspending device with the stopper of FIG. It is a figure. The same reference numerals denote the same objects throughout the drawings.

In FIG. 1, reference numeral 1 is a housing for housing an electronic circuit unit, and the electronic circuit unit includes a power supply device 2, a printed board unit 3, a recording device 6, and the like. The door is not shown,
It is provided in a part of the housing 1 so as to be openable and closable.

Fasteners (three in the figure) 10 having a U-shaped through hole 14 as shown in FIG. 2 (a) are fixed to the frame 8 of the housing 1 housing the electronic circuit unit. Fasteners (two in the figure) 9 having a groove 16 are fixed to the frame 8 above the fastener 10 as shown in FIG.

On the other hand, the shelf 13 is provided with an L-shaped suspending tool (three in the figure) 11 as shown in FIG.
Is inserted into the through hole 14 of the stopper 10. Also, shelves
A chain 15 as shown in FIG. 2 (b) is provided on the opposite side of the L-shaped hanging tool 11 to the chain 13, and the hanging tool 12 is provided at the tip of the chain 15.
The suspending tool 12 has a bolt shape and a threaded portion, and the chain 15 is fixed by the nut 18 with the threaded portion, and further has a locking portion 17 that is locked in the groove 16 of the stopper 9.

At the time of inspection, etc., open the door 7 to the metal fitting 10 of the frame 8,
The hanging tool 11 of the shelf board 13 is inserted and the shelf board 8 is attached to the frame 8. Further, the hanging tool 12 at the tip of the chain 15 attached to the shelf plate 13 is hooked on the stopper 9 of the upper frame 8 to form the shelf plate 13 in a state in which the shelf plate 13 is substantially perpendicular to the frame surface.

By placing the tester 4 on the shelf formed on the surface of the frame 8 as described above, the inspection work of the electronic circuit units such as the printed board unit 3, the power supply device 2 and the recording device 6 can be easily performed.

Since not only the tester 4 but also tools and the like can be placed on the shelf, it can be applied to improve workability in assembling the device.

Moreover, since it is not necessary to place the tester 4 directly on the floor as in the conventional case, it is said that the operability of the tester is deteriorated, the code does not reach the inspection place at a high place, and a place for placing a dedicated stand is taken. There is no trouble.

The shelf board 13 of the present invention may be housed inside the door of the housing, and in the case where a plurality of electronic devices are arranged, the shelf board 13 is stored in a common place, It may be used efficiently during maintenance and inspection work.

[Effect of device]

As described above, according to the present invention, a shelf plate that is easily removable is provided on the frame of the housing, and a shelf for mounting the tester is formed at the time of inspection. The operability can be improved.
In addition, there is no obstacle to occupy the space for the tester stand.
