The operation panel 1 has a rear edge connected to the rear edge of the relay stand main body 5 via a hinge, and is attached to the relay stand main body 5 so as to be able to open upward.

On the other hand, for convenience of the operator's writing work, a writing board 2 is attached to the front side of the operation panel 1, which also serves as a protection board for the switch panel parts. This writing board 2 is formed so as to cover the upper part of the shelf 3, including the upper part of the switch panel box, and is attached so as to be able to slide on the upper edge of the shelf 3 by a desired amount in the front-rear direction.

It is desired that the switch panel parts of the telephone relay stand constructed in this manner be easy to maintain and inspect.

[Conventional technology]

FIG. 4 is a front view of a conventional relay stand, FIG. 5 is a plan view, and FIG. 6 is a side view.

In FIGS. 4 to 6, the writing board 2 is fixed to the upper surface of a laterally long rectangular writing board frame 6. As shown in FIGS. The writing board 2 is placed on the relay stand main body 5 so that the lower surface of the lower side edge 6A of the writing board frame 6 is in contact with the upper end surface of the side plate of the shelf 3. In addition, shelf side plate 3
An angled stopper plate 9 is fixed to A with machine screws 10 so that the lower surface of the horizontal member is in contact with the upper surface of the lower frame edge 6A.

With this configuration, the stopper plate 9
The vertical member functions as a guide plate, and the horizontal member functions to prevent the writing board frame 6 from lifting up. Therefore, the writing board 2 can be slid on the relay stand main body 5 in the front-back direction.

Further, a guide pin 7 is provided to protrude from the back side plate of the writing board frame 6 and is fitted into a hole in the operation panel front plate member 1A of the operation panel 1 when the operation panel 1 of the stopper plate 9 is closed.

On the other hand, push the writing board 2 forward, and with the front edge of the writing board 2 in close contact with the front edge of the operation panel 1, the neck fits into the hole of the shelf 3, and the screw tip is inserted into the writing board frame 6. It is provided with a fixing screw 8 that is screwed into the screw hole of.

Therefore, when the relay stand is in operation, the writing board 2
The front edge of the operation panel 1 is in close contact with the front edge of the operation panel 1, and this state is maintained by the fixing screw 8, and the guide pin 7 is engaged with the operation panel front plate member 1A, so that the operation panel 1 is in a closed state. is retained.

To perform maintenance and inspection on the operation panel 1, loosen the fixing screws 8, pull out the writing board 2 toward you, and tighten the guide pins 7.
and release the engagement with the operation panel front plate member 1A. As a result, the operation panel 1 can be opened upward using the hinge as a fulcrum.

Note that when the writing board 2 is pulled out toward the front, the stopper plate 9 comes into contact with the frame member at the tip of the writing board frame 6, so that the amount of withdrawal is regulated. Therefore, the writing board 2 will not fall off from the relay stand main body 5.

[Problem that the invention attempts to solve]

As mentioned above, since the upper part of the switch panel box is covered with a writing board, it is necessary to remove the writing board in order to perform maintenance and inspection of the switch panel parts.

However, the conventional structure described above has a problem in that the horizontal member of the stopper plate is located above the lower edge of the frame and the writing plate cannot be removed unless the stopper plate is removed.

[Means for solving problems]

In order to solve the above-mentioned problems of the conventional art, the present invention provides, as shown in FIG. The structure is such that a notch 20 larger than the shape of the stopper plate 9 in plan view is provided in a portion of the lower side edge 6A of the frame facing the stopper plate 9.

[Effect]

According to the means of the present invention, when the writing board 2 is once pulled out to the front side, the engagement between the writing board 2 and the operation panel is released, and the operation panel is opened upward, the writing board 2 can be moved further back than the predetermined position.

Therefore, the notch 20 provided in the lower frame edge 6A
The writing board 2 is advanced so that it is in a position opposite to the stopper plate 9 fixed to the shelf side plate 3A. As a result, when the writing board 2 is lifted, the cutout 20 portion passes through the stopper plate 9, so that it does not become an obstacle to lifting the writing board 2 and removing it from the relay stand main body 5.

〔Example〕

The present invention will be specifically explained below with reference to the illustrated embodiments. Note that the same reference numerals indicate the same objects throughout the figures.

FIG. 1 is a perspective view of a main part of an embodiment of the present invention, and FIG. 2 a, b, and c are respectively procedural diagrams for maintenance and inspection of the relay stand of the present invention.

As shown in FIG. 1, the writing board 2 has a writing board frame 6.
The lower edge 6 of the writing board frame 6 is fixed to the upper surface of the writing board frame 6.
The lower surface of A is in contact with the upper end surface of the shelf side plate 3A of the shelf 3. Further, an angled stopper plate 9 is fixed to the shelf side plate 3A with machine screws 10 so that the lower surface of the horizontal member is in contact with the upper surface of the lower frame edge 6A.

Therefore, the vertical member of the stopper plate 9 functions as a guide plate, the horizontal member functions to prevent the writing board frame 6 from lifting up, and the writing board 2 slides on the relay stand main body 5 in the front-back direction. It is possible.
