2. Description of the Related Art For example, switches and variable resistors for driving a heater and light emitting devices such as a lamp and an LED for displaying an operation state of a device are provided on an operation section of a device such as an oil heater. The element is mounted. These electrical components are arranged on a printed board made of bakelite or epoxy resin, or on an operation section frame made of synthetic resin, and the printed board is fixed to the device via the operation section frame.

That is, commercially available display devices and switches, such as LEDs, which are electrical components attached to a printed circuit board or the like, need to have a certain size and shape, and an operation portion and a display portion are provided near the surface of the device. To position it, the fixed position of the printed circuit board is inside the device. For this reason, an opening for mounting an operation unit frame is provided on the surface of equipment such as an oil heater, and this operation unit frame is fixed to the surface of the equipment, and the surface of the operation unit of the equipment has various operation displays. Is covered with a printed display board.

On the other hand, recent card-type calculators and the like include a switch which is an operation unit on a flexible sheet plate and an LCD display having no light emission function incorporated as a display unit. If the operation unit and display unit can be configured in a sheet shape even with a heater, the operation unit can be easily configured by sticking it to the surface of the equipment frame with double-sided adhesive tape, etc. Because of the large number, there is a possibility of significant cost reduction.

[0005]

A display used in a card type computer or the like is a fluorescent display tube or an LE.
This is an LCD display that uses reflected light instead of D. This L
Since the thickness of the CD display can be made very small and the power consumption is low, the card type computer has only become practical by using this LCD display. L other than LCD
The technology using an indicator such as an ED has not been completed.

As an especially important operation method for an oil heater, there is a method of manually fixing the combustion amount between a minimum combustion amount and a maximum combustion amount, and a slide volume is used for this purpose. In addition, the conventional volume always requires a mechanical structure, and it has never been possible to incorporate this type of volume into a card type that cannot form a movable part.

A recent oil heater uses a large operation switch with a built-in light emitting lamp, and it is preferable that the operation state can be understood at a glance even if it is placed in a corner of a slightly dim room. It is practically impossible to use an LCD display used for a card-type computer or the like as a display unit of the PC. For this reason, it is extremely difficult to immediately use a plate-shaped operation unit with a flexible sheet plate used for a card-type calculator as an operation unit for an oil heater from both sides of the operation display and volume input. Met.

It is a spacer having an adhesive property at the time of joining, and the wiring pattern i of the second sheet plate 4 is held so as not to be contacted by the gap forming member 5 while facing the conductor 2 when bent.
In other portions, the thicknesses of the two sheet plates 1 and 4 overlapped by the spacer 14 are made uniform.

For this reason, when the wiring pattern i of the second sheet plate 4 is pressed, the wiring pattern i comes into contact with the conductor 2 and outputs a specific resistance value between the terminals de and e. The variable resistance data is output from the end of the wiring pattern a drawn out to the wiring plate 6, and the device can be directly controlled. Further, if an A / D converter is interposed at the end of the wiring pattern a drawn out to the wiring plate 6, the pressed position of the resistance data between the terminals d and e of the thin film resistor 3 is determined. What percentage is from the end of No. 3 can be taken as digital data by a microcomputer and processed.

If the terminals d and e of the wiring pattern are L-shaped and the portions on both sides of a large number of independent conductors 2 are directly connected to the terminals de and e, the pushing positions at both ends may be slightly different. The minimum and maximum resistance values can now be entered reliably.

Reference numeral 10 denotes an LED chip mounted at an appropriate position of the wiring patterns f and g formed on the surface of the sheet plate 1. The chip-shaped LED is mounted on a chip-mounted printed board.

The strong light generated from the portion is absorbed by the translucent member 11, and the opaque member 12 guides the light absorbed by the translucent member 11 above the LED chip 10 so that the light does not escape. Irradiated from outside.

The thin-film translucent member 11 facing the LED chip 10 is formed to have a predetermined length. If the LED chips 10 are arranged so that the arrangement of the semi-transparent members 11 indicates seven-segment numerals, the LED chip 10 is simply obtained.

A gap forming member 5 formed by a conductive and flexible dish-shaped thin metal plate is located on the insulating layer 13 of the sheet plate 1. j is in contact with a gap forming member 5 formed of a dish-shaped thin metal plate.

For this reason, when the two sheet plates 1 and 4 are overlapped via the gap forming member 5 and the spacer 14, the wiring patterns h and j are held in a non-conductive state. When the part of the wiring pattern j is pressed, the dish-shaped gap forming member 5 is inverted and comes into contact with the wiring pattern h, and both wiring patterns h and j are conducted, so that a switch can be formed.

On the other hand, the wiring plate 6 connected to the wiring patterns h and j of the sheet plates 1 and 4 is formed on the wiring plate 6 continuous with the sheet plate 1. , A switch open / close signal can be extracted.

Reference numeral 7 denotes a printed sheet on which various opaque portions are printed by printing, while leaving a transparent portion on a portion of the transparent polyester film, and 7b denotes a transparent sheet coated on the back surface of the printed sheet 7. The adhesive 16 is an adhesive upper spacer that mainly adjusts the height between the translucent member 11 or the opaque member 12 and the second sheet plate 4. The printing sheet 7 is formed by arranging the upper spacer 16 on the second sheet plate 4 and bonding the second sheet plate 4, the translucent member 11 and the opaque member 12 while sandwiching the second sheet plate 4 and the opaque member 12 with the sheet plate 1. And the whole is finished in one plate 8.

If the stiffness of the sheet plates 1 and 4 and the printing sheet 7 is expected strength, the plate 8 may be configured without using the back sheet 17. If the back sheet 17 is made of an aluminum thin film and is grounded, it functions as a shield.

Reference numeral 9 denotes an operation section of an apparatus constituted by an oil heater. The operation section 9 forms a planar recess in a part of the outer surface of the apparatus, and the recess is formed by an adhesive or a double-sided adhesive sheet in the recess. It is constituted by fixing the plate 8. Therefore, for example, a hole is formed in a metal top plate of a device by pressing to form the recess and the wiring plate 6, and the plate 8 is attached to the recess to complete the process. Therefore, there is no need for components such as a conventional synthetic resin operation unit frame, a printed circuit board for display operation, and a panel on the operation unit surface, and a structure for mounting the operation unit frame on the device frame is unnecessary. , Which has enabled a significant cost reduction.

[0030]

As described above, according to the present invention, the variable resistance input and the light-emitting type display mechanism using the LEDs can be formed into one sheet-shaped plate 8 for the first time. Can be configured by attaching the plate 8. The flexible sheet plates 1 and 4 on which the wiring patterns are formed become very inexpensive when mass-produced, and the cost of parts is reduced, thereby enabling a significant cost reduction.

In addition, the operating section 9 such as an oil heater does not require the conventionally used printed circuit board and the operating section frame made of synthetic resin, and the large section provided on the device for mounting the operating section frame. An opening for mounting is not required, and the operation unit 9 of the device is not required.

Light is guided by the opaque member 12 while absorbing the light generated from the joining portion by the translucent member 11, and further sandwiched between the printing sheet 7 on which various operation displays of the device are printed and the sheet plate 1, Since the light of the LED chip 10 is irradiated from the transparent portion of the print sheet 7, a light-emitting type display can be realized only with the plate 8 that can be attached.

Furthermore, since the translucent member 11 for absorbing the light of the LED chip 10 is made of a member having a predetermined length, the LED chip 10 is arranged so that the arrangement of the members is a seven-segment arrangement. For example, it is possible to display meaningful numbers in addition to simply turning on and off the lights, and to display the room temperature, display the rank of the calorific value, or operate the safety device in the event of an abnormality as the operating part of the oil heater In this case, an error number can be displayed, and a sufficient function can be obtained as an operation unit.
