[Conventional technology]

Electronic devices, such as office machines and control devices, are equipped with various switches and display elements. Equipped with a sophisticated operator panel. This operator panel provides ease of operation and visibility. It is usually installed at the top of the device in consideration of this. The housing of an electronic device is usually It consists of a base (frame) and a cover, and in small electronic devices, the A printed wiring board and various electrical units are attached to the board, and all of these are covered with an upper cover. The structure is normal.

0003 In an electronic device having such a structure, as shown in the conventional structure of FIGS. 6 and 7, A window 3 is provided in the cover 2, and the window 3 is opened so that the switch and display element are exposed to the window 3. A pelleter panel 5 is attached. What is shown in Fig. 6 is the inside of the window 3 of the upper cover 2. 7, the operator panel 5 is fixed to the upper cover 3 side with screws 31. The one shown in Figure 1 has an operator panel 5 on the top surface of a bracket 4 fixed to a base 1. Fix it with screws 32, and make the top surface of the operator panel face window 3 of upper cover 2. It is something.

0004 The top cover 2 may be opened or closed for maintenance of the device or replenishment of consumables. Depending on the type of device, the top cover may be opened and closed on a daily basis. Ru. In the device shown in FIG. 6 in which the operator panel 5 is attached to the upper cover 2, the base 1 Connect the connector 33 on the side and the connector 34 on the operator panel 5 side using a flexible cable. The upper cover 2 is connected by a cable 35 so that there is no problem in opening and closing the upper cover 2.

[0005]

[Problem that the idea aims to solve] However, in the conventional structure shown in FIG. 6 in which the operator panel 5 is fixed to the upper cover 2, the upper cover Bending stress is applied to the flexible cable 35 every time the bar 2 is opened or closed. Therefore, in devices where the top cover 2 is frequently opened and closed, repeated bending stress may cause In the worst case, the cable 35 may be disconnected. On the other hand, the operator The above problem does not occur with the structure shown in Figure 7 in which the panel 5 is attached to the base 1 side. However, a misalignment occurred between the window 3 provided on the top cover and the operator panel 5. This not only makes the device look unsightly, but also damages the area around the window 3 and the operator panel 5. A gap 36 is created between the device and the device, which may cause noise to leak or dust to enter the inside of the device. There is a problem.

[0006] Therefore, this invention was designed to connect the operator panel 5 when the top cover 2 is opened and closed. There is no bending stress applied to the cable connected to the base 1, and the bracket can be mounted on the base 1. Even if there is a slight positional error in installing 4 or upper cover 2, the operator panel Provides a structure that prevents misalignment or gaps between the window 3 of the upper cover and the window 3 of the upper cover. This is what we are trying to do.

[0007]

[Means to solve the problem]

In this invention, the operator panel 5 is connected via an elastic body 7 that can be deformed three-dimensionally. It is attached to the base 1 side, and is placed between the operator panel 5 and the upper cover 2 in the in-plane direction of both. A positioning pair 20 is provided to prevent the orientation from shifting, and when the upper cover 2 is closed, When the operator panel 5 comes into contact with the area around the window 3 of the upper cover, the elastic body 7 is slightly compressed. The above problem is solved by creating a positional relationship that is compressed.

[0008] The elastic body 7 may be a flexible rubber sheet, plate spring, or embossed rubber. A sheet etc. can be used. The positioning pair 20 includes the front-rear position and the left-right position. 2 or 3 pairs of catches 15, 16 that regulate the directional positions, and the front, rear, left, and right directions. It can be constructed by a pair of a tapered pin 22 and a hole 23 that regulate the relative position of the can.

[0009]

[Effect]

According to the above structure, the operator panel 5 performs positioning operations when the upper cover 2 is opened and closed. The cable 2 connected to the operator panel 5 moves only slightly depending on the operation. No large bending stress is applied to 1. And when upper cover 2 is closed When the positioning pair 20 is used, the window 3 of the upper cover and the operator panel 5 are The positioning is done in the direction, that is, the front, back, left, and right directions, and the area around the window 3 is the operator panel. Since the elastic body 7 adheres tightly around the flannel 5 due to the urging force of the elastic body 7, there will be no misalignment between the two. There will be no gaps.
