て利用するためである。 After conductive electrodes, contacts, terminals, etc. are formed in each region of the plastic film 5, a driving circuit such as an IC, LSI, etc. is bonded to the electronic circuit 8a, and the surface is subsequently coated with an insulating film.
The areas to be coated are on the common electrode 6, segment electrode 77, and electronic circuit section 8a. This is because the insulating film coated on the contact electrode 6 and the segment electrode 7 (not shown in the figure) is subjected to a rubbing treatment and used to control the alignment of the liquid crystal, and the insulating film coated on the electronic circuit section 8a is used to control the alignment of the electronic circuit. This is to use it as insulation.
次に、コモン電極６の周辺にシール材１２ａを

Liquid crystal is injected into the space created by the sealing material 12a. At this time, the liquid crystal is injected using a pressure difference. In other words, the space is evacuated, the injection hole of the liquid crystal injection tube is brought close to the missing part k of the sealing material 12a, and the pressure in the space is returned to normal, thereby injecting the liquid crystal into the space. Nitrogen gas is used as the gas introduced into the space when returning the space to normal pressure. This nitrogen gas injection is performed not only into the liquid crystal cell space but also into the key contact space formed by the sealing material 12b in the same manner as described above. In this case, a hole h1 is provided in advance at a position facing the part of the plastic film 5 where the electronic circuit section 8 is formed, nitrogen gas is injected through the hole h1 , and the area around h1 is
While adhering to the LSI package, resin is injected into the missing part k of the liquid crystal injection hole to seal the whole.

h2があり両接点は離れている。 Since the electronic desktop calculator according to this embodiment uses the touch key system, pressing the keyboard 2 causes the key contacts 9a and 9b to connect with each other to perform input. When not inputting, the keyhole of the key spacer 10 is placed between the key contacts 9a and 9b.
There is h 2 and both contacts are far apart.

する手間が省ける。 The completed electronic desk calculator with liquid crystal display is
Plastic film 5 and sealing material 12a, 1
2b, there is no need to reinstall an outer case to protect internal components (liquid crystal cells, electronic circuits, etc.). Therefore, the packaging is completed simply by printing the numbers for the key top, the window frame for the display surface, etc. on the outer surface of the plastic film 5. At that time, if you also print the instruction manual for the device on the side opposite to the operation side of the case made of plastic film 5,
This saves the trouble of preparing instruction manuals to be distributed to users.

る。 Furthermore, since the electronic desktop calculator according to the present invention has a completely airtight interior, if the battery terminal 11 is coated with, for example, resin, the entire electronic circuit will be electrically insulated from the outside, making it possible to operate underwater. It becomes possible.
さらに、本実施例による電子式卓上計算機は電

There is an example in which an electronic desk calculator is displayed by passing the protruding rod through a hole in a vinyl package containing an electronic desk calculator, but according to the present invention, the part corresponding to the upper part of the liquid crystal display surface 3 of the electronic desk calculator is placed in advance. If a hole is made in the plastic film 5, it can be displayed as is.
