Description

[Detailed Description of the Invention] The present invention relates to a slide panel holding structure designed to prevent backlash.

Conventionally, slide panel holding structures have been known for various electronic devices in which a box-shaped slide panel consisting of an operation panel such as a keyboard can be pulled out from the device body when necessary and stored inside the device body when not needed. It is being

Figure 1 shows a conventional example of such a structure, where 1 is the front panel of the main body of the device, 2 is a window provided in a part of the front panel 1, and 3 is provided so that it can be freely inserted and removed from the window 2. It is a box-shaped slide panel with an operation panel 4 for appropriate switches etc. on the front, and a guide rail 5 on the bottom.
are provided, and the upper and lower surfaces of the guide rail 5 are configured to be held between a pair of rollers 6A, 6B and 7A, 7B, respectively.

In the slide panel holding structure, in order to take the slide panel 3 in and out of the device body, the guide rail 5 is moved by the rollers 6A, 6B and 7.
This is done by sliding between the rollers 6A and 7B, as shown in FIG.
By selecting the distance D between 6B or between 7A and 7B to a value that is the sum of the thickness d of the guide rail 5 and the gap α, consideration is given to providing a smooth sliding function.

However, in the slide panel holding structure configured as described above, since the gap α is provided as described above, when an attempt is made to operate the operation panel 4 by pressing a switch with the slide panel 3 pulled out, This has the disadvantage that the operability deteriorates due to looseness.

The present invention has been made to eliminate the above-mentioned drawbacks, and includes a pair of fixed rollers for holding the guide rails of a slide panel from the upper and lower surfaces at positions apart from each other, and a pair of fixed rollers for holding the guide rails of the slide panel from the upper and lower surfaces at positions apart from each other; The above-mentioned problems are solved by a configuration including a pair of pressure rollers for pressing the guide rail against the pair of fixed rollers by clamping the rail elastically from the upper and lower surfaces at positions apart from each other. be.

Hereinafter, the present invention will be described in detail with reference to drawings showing embodiments.

3 and 4 are cross-sectional views showing a slide panel holding structure according to an embodiment of the present invention, and FIG. 3 shows a state in which the slide panel is housed in the device main body,
FIG. 4 shows the state in which the slide panel is pulled out from the main body of the device.

In FIGS. 3 and 4, the same parts as in FIG. 1 are designated by the same numbers. 8A and 8B are a pair of fixed rollers provided to sandwich the guide rail 5 from above and below at positions apart from each other,
Each is supported by levers 9A and 9B and attached to a base plate 10. 11A, 11B
are a pair of pressing rollers which are provided between the fixed rollers 8A and 8B so as to clamp the guide rail 5 elastically from the upper and lower surfaces at positions apart from each other, and each roller is pressed by a common lever 12 via a fulcrum 13. and is attached to the intermediate member 14, which is fixed to the base plate 10. Also 15
is a spring and is provided between one end of the common lever 12 and one end of the lever 9B.

According to the above configuration, the guide rail 5 of the slide panel 3 is always pressed by the pair of pressure rollers 11A, 11B due to the biasing force of the spring 15, so that the guide rail 5 of the slide panel 3 always has a pair of fixed rollers 8A,
It is kept pressed against 8B. Therefore, even if the operation panel 4 is pressed while the slide panel 3 is pulled out from the main body of the device as shown in Fig. 4, no rattling will occur, improving operability and maintaining a good touch condition. can be done.

As described above, according to the present invention, since the guide rail of the slide panel is always pressed against the fixed roller by a pair of pressure rollers, a slide panel holding structure that eliminates the conventional drawbacks can be obtained. It will be done.
