Abstract

PURPOSE:To eliminate the residual bubbles in the interior part and enable smooth operation of a key switch by providing slots in a double coated adhesive sheet to be bonded to an outer bonded member and providing a hole in a portion of the outer bonded member corresponding to these slots. CONSTITUTION:There are provided a panel 1 on whose surface alphanumeric characters and displayed, a shield sheet 2 for electrostatic countermeasure, a pattern sheet 3, a spacer 4 for providing a gap between the upper and lower pattern sheets, and a double coated adhesive sheet 5 for bonding a membrane key switch to an outer bonded member 6, and several slots 8 for releasing air are provided in the adhesive sheet 5 and a hole 9 is provided in the bonded member 6 at the corresponding position. When this membrane key switch is bonded to the bonded member, bubbles in the interior part escape through the slots of the sheet and the hole of the bonded member so that the dispersion of the input load of the key is reduced and no care is required as to bubbles upon bonding, thus the working property is improved.

ところにある。[Problem to be solved by the invention 1 However, the structure of the conventional membrane key switch is
As shown in the figure, when a membrane key switch is attached to an external object, if air bubbles 7 are caught between the external object and the double-sided adhesive sheet, there is no way for the air to escape, and the switch is exposed to high temperatures. When used, the air expands and pushes up the weakest key switch from below since there is no escape area around it, so the gap between the electrodes becomes smaller, and when pressing the key manually, the key can be pressed with just a light touch. There was a problem in that the data was input. Therefore, the present invention is intended to solve these conventional problems, and its purpose is to:
It creates an escape route for air when it gets caught between the membrane key switch's double-sided adhesive sheet and the external floor to which it is attached.

徴とする。[Means for Solving the Problems] The membrane key switch structure of the present invention includes a membrane key switch having a double-sided adhesive sheet for attachment to an external adherend, and a membrane key switch structure consisting of an external adherend. The double-sided adhesive sheet is provided with grooves, and the external adherend to which the membrane key switch is attached is provided with holes in the portions corresponding to the grooves in the double-sided adhesive sheet.

間に、気泡が残ることがなくなる。[Function 1] With the above-described configuration, when air is drawn in between the double-sided adhesive sheet of a membrane key switch and an external adherend, when the key switch is pressed from above, the air flows between both sides. It passes through the grooves in the adhesive sheet and escapes from the holes in the external adherend, so that no air bubbles remain between the double-sided adhesive sheet and the external adherend.

面粘着シートである。[Example 1] Hereinafter, the present invention will be explained in detail based on an example. In Figure 1, l is a panel with numbers, alphabets, etc. displayed on its surface, 2 is a shield sheet for static electricity countermeasures, and 3 is a pattern sheet. Electrodes are arranged on the upper and lower facing surfaces, and when the key switch is pressed, , the upper and lower electrodes are in contact and the key is human power. 4 is a spacer for creating a gap between the upper and lower pattern sheets, and 5 is a double-sided adhesive sheet for attaching the membrane key switch to the external adherend 6.

接着体には、第４図のように、メンブレンキースイッチ

に空気を逃がす為の穴を設ける。The double-sided adhesive sheet No. 5 has several grooves for air to escape as shown in Figure 3, and the membrane key switch is pasted on the object to be adhered to the membrane key switch as shown in Figure 4. Provide holes to allow air to escape when the double-sided adhesive sheet is opened.

泡はなくなる。When a membrane key switch with these configurations is attached to an object and air bubbles are drawn between the key switch and the object, the air bubbles pass through the grooves of the double-sided adhesive sheet and are attached to the object. As a result, there are no air bubbles between the double-sided adhesive sheet and the external adherend.

する。[Effects of the Invention] As described above, with the structure of the present invention, if air bubbles are caught between the double-sided adhesive sheet of the membrane key switch and the external adherend, the air bubbles will remain as they are. When the temperature rises, the air expands and pushes up the key switch from below, preventing the force applied to the key from becoming extremely small, which reduces variation in the force applied to the key. There is no need to carefully affix a membrane key switch while being careful not to trap air bubbles when attaching it, which improves work efficiency.
