 本発明は、輻射熱を放射するヒータ装置に関するものである。 The present invention relates to a heater device that radiates radiant heat.
 従来、基板部に埋設された電極と複数の発熱部を有し、電極と発熱部は基板の内部において電気的に接続され、かつ、それぞれ膜状に形成された輻射ヒータ装置が、例えば特許文献1に記載されている。この装置は、電極と発熱部とが膜状に形成されているので、物体が発熱部に接触すると発熱部の温度が迅速に低下する。このため、人体が発熱部に触れたときに人への熱的不快感を低減することができる。 Conventionally, a radiation heater device having an electrode embedded in a substrate portion and a plurality of heat generating portions, the electrodes and the heat generating portion being electrically connected inside the substrate, and each formed in a film shape is disclosed in, for example, Patent Literature 1. In this apparatus, since the electrode and the heat generating part are formed in a film shape, when the object comes into contact with the heat generating part, the temperature of the heat generating part rapidly decreases. For this reason, when a human body touches a heat-emitting part, the thermal discomfort to a person can be reduced.
 また、ユーザに暖房感を与える装置として、ボディーに設けたヒータと、ボディーの上部および下部に設けた複数のセンサを備え、複数のセンサにより物体が検知されたときに、ヒータへの通電を停止するようにした装置が、例えば、特許文献2に記載されている。 In addition, as a device that gives the user a feeling of heating, a heater provided on the body and a plurality of sensors provided on the upper and lower parts of the body are provided, and energization of the heater is stopped when an object is detected by the plurality of sensors.

 上記特許文献1に記載された装置は、物体が発熱部に触れると、触れた部分の温度が急速に低下するように作用するが、物体が発熱部に触れ続けていると、触れている部分の温度が徐々に上昇し、ユーザに熱的な不快感を与えてしまう。 The device described in Patent Document 1 acts so that when the object touches the heat generating part, the temperature of the touched part rapidly decreases, but when the object continues to touch the heat generating part, the part touched The temperature of the camera gradually increases, giving the user a thermal discomfort.
 そこで、上記特許文献1に記載されたヒータ装置において、物体を検知する検知部と発熱部を一体化し、上記特許文献2に記載された装置のように、検知部により物体が検知されたときに発熱部への通電を停止するようにして、ユーザに熱的な不快感を与えないようにすることが考えられる。 Therefore, in the heater device described in Patent Document 1, the detection unit that detects an object and the heat generation unit are integrated, and when the object is detected by the detection unit as in the device described in Patent Document 2, It is conceivable to stop the energization of the heat generating part so as not to give the user a thermal discomfort.
 しかし、上記特許文献1に記載された装置において、物体を検知する検知部を発熱部と一体化する場合、物体が接触する部位と検知部との位置関係により、検知部の検知精度が低下する場合がある。具体的には、物体が接触する部位と検知部とが離れている場合や、物体が接触する部位と検知部との間に障害となる部材がある場合、検知部の検知精度が低下する可能性がある。なお、このような問題は、上記したような物体が発熱部に触れると、触れた部分の温度が急速に低下するように構成されたヒータ装置以外の装置においても同様に発生する。 However, in the apparatus described in Patent Document 1, when the detection unit that detects an object is integrated with the heat generation unit, the detection accuracy of the detection unit is lowered due to the positional relationship between the part that the object contacts and the detection unit. There is a case. Specifically, the detection accuracy of the detection unit can be reduced if the part that the object contacts is far from the detection unit, or if there is a member that becomes an obstacle between the part that contacts the object and the detection unit There is sex. Such a problem also occurs in devices other than the heater device configured such that when the object as described above touches the heat generating portion, the temperature of the touched portion rapidly decreases.
 本開示は、物体の検知精度を低下させることなく、発熱部に接触検知層を設けることを目的とする。 This disclosure is intended to provide a contact detection layer in a heat generating portion without reducing the detection accuracy of an object.
 本開示の1つの観点によれば、輻射熱を放射するヒータ装置は、通電により発熱して輻射熱を放射するシート状の発熱部と、物体と接触する接触面(St)を有し、該接触面への物体の接触を検知するシート状の接触検知層と、を備え、発熱部は、接触検知層の接触面と反対側に配置されている。 According to one aspect of the present disclosure, a heater device that radiates radiant heat includes a sheet-like heat generating portion that generates heat when energized and radiates radiant heat, and a contact surface (St) that contacts an object. And a sheet-like contact detection layer for detecting contact of an object with the heat generating portion is disposed on the side opposite to the contact surface of the contact detection layer.
 このような構成によれば、発熱部は、接触検知層の接触面と反対側に配置され、接触検知層は接触面への物体の接触を直接検出するので、物体の検知精度を低下させることなく、発熱部に接触検知層を設けることができる。 According to such a configuration, the heat generating portion is disposed on the side opposite to the contact surface of the contact detection layer, and the contact detection layer directly detects the contact of the object with the contact surface, thereby reducing the object detection accuracy. In addition, a contact detection layer can be provided in the heat generating portion.

 図3は、ヒータ本体40の断面図である。ヒータ本体40は、図3における紙面上側を加熱対象側、すなわち、人体側として輻射熱を放射する。ヒータ本体40は、発熱部20、および接触検知層30を有している。 FIG. 3 is a cross-sectional view of the heater body 40. The heater body 40 radiates radiant heat with the upper side in FIG. 3 as the heating target side, that is, the human body side. The heater body 40 includes the heat generating part 20 and the contact detection layer 30.
 接触検知層30は、発熱部20の加熱対象物側に配置されている。接触検知層30は、第1絶縁層31、第1導電部34a、第2絶縁層32、第2導電部34bおよび表面部材35を有している。 The contact detection layer 30 is disposed on the heating object side of the heat generating part 20. The contact detection layer 30 includes a first insulating layer 31, a first conductive portion 34a, a second insulating layer 32, a second conductive portion 34b, and a surface member 35.
 第1絶縁層31および第2絶縁層32は、それぞれ高い絶縁性を有している。また、第1絶縁層31および第2絶縁層32は、それぞれシート状を成している。 The first insulating layer 31 and the second insulating layer 32 have high insulation properties. Moreover, the 1st insulating layer 31 and the 2nd insulating layer 32 have comprised the sheet form, respectively.
 第1導電部34aは、第1絶縁層31の一面側に配置されており、第2導電部34bは、第2絶縁層32の一面側に配置されている。第1絶縁層31および第2絶縁層32は、第1導電部34aと第2導電部34bとが空気層2を挟んで対向するように配置されている。 The first conductive portion 34 a is disposed on the one surface side of the first insulating layer 31, and the second conductive portion 34 b is disposed on the one surface side of the second insulating layer 32. The first insulating layer 31 and the second insulating layer 32 are arranged so that the first conductive portion 34a and the second conductive portion 34b face each other with the air layer 2 interposed therebetween.
 表面部材35は、第1絶縁層31の他面側、すなわち、加熱対象物側に配置されている。表面部材35の第1絶縁層31と反対側の面、すなわち、加熱対象物側の面は、物体と接触する接触面Stとなっている。表面部材35の第1絶縁層31側の面は、第1絶縁層31に接着されている。表面部材35は、例えば、フィルム状のポリイミド樹脂により構成されている。表面部材35は、熱抵抗を増加させるためだけでなく、ヒータ本体40を保護するとともに見栄えを向上するために設けられている。 The surface member 35 is disposed on the other surface side of the first insulating layer 31, that is, on the heating object side. The surface of the surface member 35 opposite to the first insulating layer 31, that is, the surface on the heating object side is a contact surface St that contacts an object. The surface of the surface member 35 on the first insulating layer 31 side is bonded to the first insulating layer 31. The surface member 35 is made of, for example, a film-like polyimide resin. The surface member 35 is provided not only for increasing the thermal resistance, but also for protecting the heater body 40 and improving the appearance.
 第1絶縁層31および第2絶縁層32の外縁部には、固定部33が配置されている。この固定部33により、第1絶縁層31および第2絶縁層32の間に隙間が設けられている。すなわち、第1絶縁層31および第2絶縁層32の間に空気層2が形成されている。 A fixing portion 33 is disposed on the outer edge portions of the first insulating layer 31 and the second insulating layer 32. Due to the fixing portion 33, a gap is provided between the first insulating layer 31 and the second insulating layer 32. That is, the air layer 2 is formed between the first insulating layer 31 and the second insulating layer 32.
 接触検知層30は、物体と接触する接触面Stを有し、この接触面Stへの物体の接触を検知する。物体が表面部材35を介して接触面Stに接触しておらず、第1導電部34aと第2導電部34bが非接触の状態では、第1導電部34aと第2導電部34bの間は非導通状態となる。しかし、物体が接触面Stに接触し、第1絶縁層31および第1導電部34aが変形して第1導電部34aと第2導電部34bが接触状態になると、第1導電部34aと第2導電部34bの間は導通状態となる。 The contact detection layer 30 has a contact surface St that comes into contact with an object, and detects the contact of the object with the contact surface St. When the object is not in contact with the contact surface St via the surface member 35 and the first conductive portion 34a and the second conductive portion 34b are not in contact with each other, the gap between the first conductive portion 34a and the second conductive portion 34b is It becomes a non-conductive state. However, when the object comes into contact with the contact surface St and the first insulating layer 31 and the first conductive portion 34a are deformed so that the first conductive portion 34a and the second conductive portion 34b are in contact with each other, the first conductive portion 34a and the first conductive portion 34a The two conductive portions 34b are in a conductive state.
 発熱部20は、シート状をなしており、通電により発熱して輻射熱を放射する。発熱部20は、接触検知層30の接触面Stと反対側に、接触検知層30と一体化して設けられている。発熱部20は、上記特許文献1に記載されたものと同様の構成となっている。すなわち、発熱部20は、基板部と、基板部に埋設された電極と複数の発熱部(いずれも図示せず)を有している。電極と発熱部は基板の内部において電気的に接続され、かつ、それぞれ膜状に形成されている。発熱部20は、電極と発熱部とが膜状に形成されているので、物体が発熱部20に接触すると発熱部の温度が迅速に低下する。このため、例えば、人体が発熱部20に触れたときに人への熱的不快感を低減することができる。 The heat generating portion 20 has a sheet shape, and generates heat when energized to emit radiant heat. The heat generating unit 20 is provided integrally with the contact detection layer 30 on the side opposite to the contact surface St of the contact detection layer 30. The heat generating part 20 has the same configuration as that described in Patent Document 1. That is, the heat generating unit 20 includes a substrate unit, an electrode embedded in the substrate unit, and a plurality of heat generating units (none of which are shown). The electrode and the heat generating portion are electrically connected inside the substrate and are each formed in a film shape. Since the electrode and the heat generating part are formed in a film shape, the temperature of the heat generating part rapidly decreases when an object comes into contact with the heat generating part 20. For this reason, for example, when a human body touches the heat-emitting part 20, the thermal discomfort to a person can be reduced.
 また、発熱部20の板厚は、第1絶縁層31の板厚と第2絶縁層32の板厚を合わせた厚さよりも厚くなっており、発熱部20の剛性は、第1絶縁層31と第2絶縁層32を合わせたものより高くなっている。 Further, the thickness of the heat generating portion 20 is thicker than the total thickness of the first insulating layer 31 and the second insulating layer 32, and the rigidity of the heat generating portion 20 is the first insulating layer 31. And higher than the sum of the second insulating layers 32.
 図4は、本実施形態に係るヒータ装置1の電気的構成を示すブロック図である。ヒータ装置1は、接触検知部100、制御部80および発熱部20を有している。 FIG. 4 is a block diagram showing an electrical configuration of the heater device 1 according to the present embodiment. The heater device 1 includes a contact detection unit 100, a control unit 80, and a heat generation unit 20.
 接触検知部100は、対向配置された第1導電部34aと第2導電部34bの間が導通状態であるか非導通状態であるか否かに基づいて接触検知層30への物体の接触を電気的に検知し、物体が接触しているか否かを示す信号を制御部80へ出力する。 The contact detection unit 100 determines whether the object is in contact with the contact detection layer 30 based on whether the first conductive unit 34a and the second conductive unit 34b that are arranged to face each other are in a conductive state or a non-conductive state. A signal that is detected electrically and indicates whether or not an object is in contact is output to the control unit 80.
 制御部80は、CPU、RAM、ROM、I/O等を備えたコンピュータとして構成されており、CPUはROMに記憶されたプログラムに従って各種処理を実施する。 The control unit 80 is configured as a computer including a CPU, a RAM, a ROM, an I / O, and the like, and the CPU performs various processes according to a program stored in the ROM.
 制御部80は、接触検知部100により物体が接触したことが検知されると、発熱部への通電を停止する制御処理を実施する。 When the contact detection unit 100 detects that an object has come into contact, the control unit 80 performs a control process to stop energization of the heat generating unit.
 図5は、この制御処理のフローチャートである。制御部80は、定期的に図5に示す処理を実施する。なお、各図面のフローチャートにおける各制御ステップは、制御部80が有する各種の機能実現部を構成している。 FIG. 5 is a flowchart of this control process. The control unit 80 periodically performs the process shown in FIG. In addition, each control step in the flowchart of each drawing comprises the various function implementation | achievement part which the control part 80 has.
 まず、制御部80は、ステップS100で、接触面Stへの物体の接触を検出したか否かを判定する。具体的には、接触検知部100より入力される信号に基づいて接触面Stへの物体の接触を検出したか否かを判定する。 First, in step S100, the control unit 80 determines whether or not the contact of an object with the contact surface St is detected. Specifically, it is determined based on a signal input from the contact detection unit 100 whether or not contact of an object with the contact surface St has been detected.
 ここで、接触面Stへの物体の接触がなく、第1導電部34aと第2導電部34bの間が開放となっている場合、接触検知部100より制御部80に物体が接触していない旨の信号が入力される。この場合、制御部80は、接触面Stへの物体の接触がないと判定し、ステップS104で、ヒータ出力を停止させることなく、発熱部20への通電を継続し、本処理を終了する。 Here, when there is no contact of the object with the contact surface St and the space between the first conductive part 34a and the second conductive part 34b is open, the object is not in contact with the control unit 80 from the contact detection unit 100. A signal to that effect is input. In this case, the control unit 80 determines that there is no contact of the object with the contact surface St, and in step S104, continues the energization to the heat generating unit 20 without stopping the heater output, and ends this process.
 また、接触面Stに物体が接触すると、第1絶縁層と第1導電部34aが変形し、第1導電部34aと第2導電部34bの間が短絡する。すると、接触検知部100より制御部80に物体が接触している旨の信号が入力される。この場合、制御部80は、接触面Stへの物体の接触があると判定し、ステップS102でヒータ出力を停止させる。具体的には、発熱部20への通電を停止させ、本処理を終了する。 Also, when an object comes into contact with the contact surface St, the first insulating layer and the first conductive portion 34a are deformed, and the first conductive portion 34a and the second conductive portion 34b are short-circuited. Then, a signal indicating that an object is in contact with the control unit 80 is input from the contact detection unit 100. In this case, the control unit 80 determines that there is an object contact with the contact surface St, and stops the heater output in step S102. Specifically, energization to the heat generating unit 20 is stopped, and this process is terminated.
 上記したように、ヒータ装置1は、輻射熱を放射するヒータ装置であって、シート状の発熱部20と、シート状の接触検知層30と、を備える。発熱部20は、通電により発熱して輻射熱を放射する。接触検知層30は、物体と接触する接触面Stを有し、該接触面Stへの物体の接触を検知する。発熱部20は、接触検知層30の接触面と反対側に配置されている。 As described above, the heater device 1 is a heater device that radiates radiant heat, and includes the sheet-like heat generating portion 20 and the sheet-like contact detection layer 30. The heat generating part 20 generates heat by energization and radiates radiant heat. The contact detection layer 30 has a contact surface St that comes into contact with an object, and detects contact of the object with the contact surface St. The heat generating unit 20 is disposed on the side opposite to the contact surface of the contact detection layer 30.
 このような構成によれば、発熱部20は、接触検知層30の接触面Stと反対側に配置され、接触検知層30は接触面Stへの物体の接触を直接検知するので、物体の検知精度を低下させることなく、発熱部に接触検知層を設けることができる。 According to such a configuration, the heat generating unit 20 is disposed on the opposite side of the contact surface St of the contact detection layer 30, and the contact detection layer 30 directly detects the contact of the object with the contact surface St. A contact detection layer can be provided in the heat generating part without reducing accuracy.
 また、接触検知層30は、シート状の第1絶縁層31と、第1絶縁層31の一面に形成された第1導電部34aと、シート状の第2絶縁層32と、第2絶縁層32の一面に形成された第2導電部34bと、を有している。そして、第1絶縁層31および第2絶縁層32は、第1導電部34aと第2導電部34bとが空気層2を挟んで対向するように配置されている。 The contact detection layer 30 includes a sheet-like first insulating layer 31, a first conductive portion 34a formed on one surface of the first insulating layer 31, a sheet-like second insulating layer 32, and a second insulating layer. 32, a second conductive portion 34b formed on one surface. The first insulating layer 31 and the second insulating layer 32 are arranged such that the first conductive portion 34a and the second conductive portion 34b face each other with the air layer 2 in between.
 これによれば、物体が接触したときの圧力により第1導電部34aと第2導電部34bとが接触し、この第1導電部34aと第2導電部34bが導通状態となっているか否かに基づいて物体の接触を検知するので、簡素な構成で物体の接触を検知することができる。 According to this, whether or not the first conductive portion 34a and the second conductive portion 34b are in contact with each other by the pressure when the object is in contact, and the first conductive portion 34a and the second conductive portion 34b are in a conductive state. Therefore, the contact of the object can be detected with a simple configuration.
 また、第1導電部34aと第2導電部34bとが導通状態となったか否かに基づいて物体の接触を検知する接触検知部100を備え、制御部80は、接触検知部100により物体の接触が検知された場合、発熱部20への通電を停止させるので、安全性を確保することができる。 In addition, the control unit 80 includes a contact detection unit 100 that detects contact of an object based on whether the first conductive unit 34 a and the second conductive unit 34 b are in a conductive state. When contact is detected, the power supply to the heat generating unit 20 is stopped, so that safety can be ensured.
 発熱部20の板厚は、第1絶縁層31の板厚と第2絶縁層32の板厚を合わせた厚さよりも厚くなっており、発熱部20の剛性は、第1絶縁層31と第2絶縁層32を合わせたものよりも高くなっているので、物体が接触したときの圧力による発熱部20の変形を抑制することができ、より物体接触の検出精度を向上することができる。 The thickness of the heat generating portion 20 is thicker than the total thickness of the first insulating layer 31 and the second insulating layer 32, and the rigidity of the heat generating portion 20 is the same as that of the first insulating layer 31 and the first insulating layer 31. Since it is higher than the sum of the two insulating layers 32, deformation of the heat generating portion 20 due to pressure when an object comes into contact can be suppressed, and detection accuracy of object contact can be further improved.
 (第2実施形態)
 第2実施形態に係るヒータ装置について図6を用いて説明する。上記第1実施形態のヒータ装置1は、シート状の1つの第1導電部34aが第1絶縁層31の一面に形成されるとともに、シート状の1つの第2導電部34bが第2絶縁層32の一面に形成されている。これに対し、本実施形態のヒータ装置1は、複数のシート状の第1導電部34aが第1絶縁層31の一面に形成されるとともに、複数のシート状の第2導電部34bが第2絶縁層32の一面に形成されている。また、本実施形態のヒータ装置1は、第1導電部34aと第2導電部34bとの間隔を維持する複数のスペーサ36を備えている。

In addition, the heater device 1 of the present embodiment includes a plurality of spacers 36 that maintain the distance between the first conductive portion 34a and the second conductive portion 34b.
 第1絶縁層31および第2絶縁層32は、第1導電部34aと第2導電部34bとが空気層2を挟んで対向するように配置されている。 The first insulating layer 31 and the second insulating layer 32 are arranged so that the first conductive portion 34a and the second conductive portion 34b face each other with the air layer 2 interposed therebetween.
 また、スペーサ36は、円筒形状を成しており、例えば、アクリル樹脂により構成されている。スペーサ36は、第1絶縁層31と第2絶縁層32との間に空気層2を形成している。スペーサ36は、接着剤を用いて第1絶縁層31と第2絶縁層32との間に接着されている。 The spacer 36 has a cylindrical shape, and is made of, for example, acrylic resin. The spacer 36 forms the air layer 2 between the first insulating layer 31 and the second insulating layer 32. The spacer 36 is bonded between the first insulating layer 31 and the second insulating layer 32 using an adhesive.
 本実施形態では、上記第1実施形態と共通の構成から奏される同様の効果を上記第1実施形態と同様に得ることができる。 In the present embodiment, the same effect that is obtained from the configuration common to the first embodiment can be obtained as in the first embodiment.

That is, the third insulating layer 21 is provided so as to surround in three directions, that is, the contact detection layer 30 side of the heat generating unit 20, the opposite side of the heat generating unit 20 on the contact detection layer 30 side, and the side surface side of the heat generating unit 20.

 本実施形態では、上記第1実施形態と共通の構成から奏される同様の効果を上記第1実施形態と同様に得ることができる。 In the present embodiment, the same effect that is obtained from the configuration common to the first embodiment can be obtained as in the first embodiment.
 さらに、ヒータ装置1は、発熱部20の接触検知層30側および発熱部20の接触検知層30側の反対側に配置された第3絶縁層21を備える。第3絶縁層21の板厚が、第1絶縁層31の板厚と第2絶縁層32の板厚を合わせた厚さよりも厚くなっている。第3絶縁層21の剛性は、第1絶縁層31と第2絶縁層32を合わせたものより高くなっている。 Furthermore, the heater device 1 includes a third insulating layer 21 disposed on the contact detection layer 30 side of the heat generating unit 20 and on the opposite side of the heat detection unit 20 on the contact detection layer 30 side.

 これによれば、第3絶縁層21の剛性は、第1絶縁層31と第2絶縁層32を合わせたものより高くなっているので、物体が接触したときの圧力による発熱部20の変形を抑制することができ、より物体接触の検出精度を向上することができる。 According to this, the rigidity of the third insulating layer 21 is higher than that of the combination of the first insulating layer 31 and the second insulating layer 32.

 (第4実施形態)
 第4実施形態に係るヒータ装置について図8を用いて説明する。上記第1実施形態のヒータ装置1は、上記第1実施形態のヒータ装置1と比較して、さらに、ヒータ収納部60の底面に、断熱材50側に突出する突出部70が形成されている点が異なる。
(Fourth embodiment)
A heater device according to a fourth embodiment will be described with reference to FIG. In the heater device 1 of the first embodiment, as compared with the heater device 1 of the first embodiment, a protrusion 70 that protrudes toward the heat insulating material 50 is further formed on the bottom surface of the heater housing 60. The point is different.
 突出部70は、ヒータ収納部60内の面であって、接触面Stに物体が接触したときに物体の接触による加重がかかる面に形成されている。具体的には、突出部70は、ヒータ収納部60の底面に、接触面St側に突出するよう形成されている。 The protrusion 70 is a surface in the heater housing 60 and is formed on a surface to which a load is applied due to the contact of the object when the object contacts the contact surface St. Specifically, the protruding portion 70 is formed on the bottom surface of the heater accommodating portion 60 so as to protrude toward the contact surface St.
 ヒータ収納部60の底面に突出部70が形成されていない構成では、ユーザの指により接触面Stに荷重がかかったときに、接触検知層30に荷重が分散して伝わる。このため、第1導電部34aと第2導電部34bを接触状態にするためには大きな荷重で接触面Stを押す必要がある。すなわち、物体の検知精度がよくない。 In the configuration in which the protruding portion 70 is not formed on the bottom surface of the heater housing portion 60, the load is distributed and transmitted to the contact detection layer 30 when a load is applied to the contact surface St by the user's finger. For this reason, in order to make the 1st electroconductive part 34a and the 2nd electroconductive part 34b a contact state, it is necessary to push the contact surface St with a big load. That is, the object detection accuracy is not good.
 これに対し、本実施形態のようにヒータ収納部60の底面に突出部70が形成されている構成では、ユーザの指により接触面Stに荷重がかかったときに、突出部70に荷重が集中して伝わる。このため、比較的小さな荷重で第1導電部34aと第2導電部34bを接触状態にすることができる。すなわち、より物体の検知精度を向上することができる。 On the other hand, in the configuration in which the protrusion 70 is formed on the bottom surface of the heater housing 60 as in the present embodiment, when the load is applied to the contact surface St by the user's finger, the load is concentrated on the protrusion 70. It is transmitted. For this reason, the 1st electroconductive part 34a and the 2nd electroconductive part 34b can be made into a contact state with a comparatively small load. That is, the object detection accuracy can be further improved.

 (4)上記各実施形態では、物体が発熱部に触れると、触れた部分の温度が急速に低下するように構成されたヒータ装置に適用した。しかし、触れた部分の温度が急速に低下するように構成されたヒータ装置以外の装置に適用してもよい。 (4) In each of the embodiments described above, the present invention is applied to a heater device configured such that when an object touches the heat generating portion, the temperature of the touched portion rapidly decreases. However, you may apply to apparatuses other than the heater apparatus comprised so that the temperature of the part which touched may fall rapidly.

As a result, the rigidity of the heat generating portion 20 is higher than that of the combination of the first insulating layer 31 and the second insulating layer.
 しかし、発熱部20の剛性が、第1絶縁層31と第2絶縁層32を合わせたものより高くなる態様は、このようなものに限られない。例えば、発熱部20がリブを有することで、発熱部20の剛性が、第1絶縁層31と第2絶縁層32を合わせたものより高くなってもよい。また例えば、発熱部20が第1絶縁層31よりも第2絶縁層32よりも弾性率の高い材料を含むことにより、発熱部20の剛性が、第1絶縁層31と第2絶縁層32を合わせたものより高くなってもよい。 However, the aspect in which the rigidity of the heat generating portion 20 is higher than that of the first insulating layer 31 and the second insulating layer 32 is not limited to this. For example, the heat generating part 20 may have a rib, so that the rigidity of the heat generating part 20 may be higher than that of the first insulating layer 31 and the second insulating layer 32 combined. Further, for example, when the heat generating part 20 includes a material having a higher elastic modulus than the first insulating layer 31, the rigidity of the heat generating part 20 is increased between the first insulating layer 31 and the second insulating layer 32. May be higher than combined.
 (6)上記実施形態では、第3絶縁層21の板厚は、第1絶縁層31の板厚と第2絶縁層32の板厚を合わせた厚さよりも厚くなっている。そしてその結果、第3絶縁層21の剛性は、第1絶縁層31と第2絶縁層を合わせたものより高くなっている。 (6) In the above embodiment, the thickness of the third insulating layer 21 is larger than the total thickness of the first insulating layer 31 and the second insulating layer 32. As a result, the rigidity of the third insulating layer 21 is higher than that of the combination of the first insulating layer 31 and the second insulating layer.
 しかし、第3絶縁層21の剛性が、第1絶縁層31と第2絶縁層32を合わせたものより高くなる態様は、このようなものに限られない。例えば、第3絶縁層21がリブを有することで、第3絶縁層21の剛性が、第1絶縁層31と第2絶縁層32を合わせたものより高くなってもよい。また例えば、第3絶縁層21が第1絶縁層31よりも第2絶縁層32よりも弾性率の高い材料を含むことにより、第3絶縁層21の剛性が、第1絶縁層31と第2絶縁層32を合わせたものより高くなってもよい。 However, the aspect in which the rigidity of the third insulating layer 21 is higher than that of the first insulating layer 31 and the second insulating layer 32 is not limited to this. For example, when the third insulating layer 21 has ribs, the rigidity of the third insulating layer 21 may be higher than that of the first insulating layer 31 and the second insulating layer 32 combined. Further, for example, when the third insulating layer 21 includes a material having a higher elastic modulus than the first insulating layer 31 than the second insulating layer 32, the rigidity of the third insulating layer 21 is increased between the first insulating layer 31 and the second insulating layer 31. It may be higher than the sum of the insulating layers 32.
 (7)上記各実施形態では、第1導電部34aと第2導電部34bの接触、非接触に応じて物体の接触が検知される。しかし、接触面への物体の接触を検知する方法は、このようなものに限られず、例えば、静電容量方式で接触面への物体の接触を検知する方法が採用されてもよい。物体の接近によって静電容量が変化する静電容量検知シートを、第1導電部34aと第2導電部34bの代わりに用いられる。この場合、静電容量検知シートが接触検知層の構成要素となる。そしてこの場合、発熱部20は、静電容量検知シートの接触面Stと反対側に配置される。 (7) In each of the above embodiments, the contact of the object is detected according to the contact or non-contact of the first conductive portion 34a and the second conductive portion 34b. However, the method of detecting the contact of the object with the contact surface is not limited to this, and for example, a method of detecting the contact of the object with the contact surface by a capacitance method may be employed.
