Description
【０００１】[0001]
この考案は、電卓などの小型電子機器に用いられる液晶表示装置の収納構造に 関する。 The present invention relates to a storage structure for a liquid crystal display device used in a small electronic device such as a calculator.
【０００２】[0002]
電卓などの小型電子機器では、液晶表示装置の表示を見やすくするために、液 晶表示装置の裏面をバックライト装置で照明して、液晶表示装置の表示を明るく している。このような液晶表示装置の収納構造は、従来、図２に示すように、上 ケース１の所定個所に表示用の開口部２を形成し、この開口部２に透明なガラス 板３を嵌め込んで両面テープ４により接着し、上ケース１の下面に収納ケース５ を開口部２と対応させてビス６により取り付け、この収納ケース５内に上側より 液晶表示装置７およびバックライト装置８を積層配置した構造になっている。こ の場合、バックライト装置８は、取付ケース９の下部に発光ダイオードを基板上 に多数配列した平面型光源１０を設け、取付ケース９の上部に平面型光源１０の 光を拡散する拡散板１１を設けた構造になっており、平面型光源１０の下面周縁 部が両面テープ４により収納ケース５の底部に接着されている。液晶表示装置７ は、その下面周縁部が両面テープ４によりバックライト装置８の上面に接着され ている。なお、収納ケース５の下側には下ケース１２が配置されている。そして 、この下ケース１２と上ケース１とによって機器ケースが構成されている。 In small electronic devices such as calculators, the back surface of the liquid crystal display device is illuminated by a backlight device to make the display on the liquid crystal display device brighter in order to make it easier to see. Conventionally, such a liquid crystal display device storage structure has a display opening 2 formed in a predetermined portion of an upper case 1 as shown in FIG. 2, and a transparent glass plate 3 is fitted into the opening 2. With a double-sided tape 4, and a storage case 5 is attached to the lower surface of the upper case 1 with a screw 6 corresponding to the opening 2, and a liquid crystal display device 7 and a backlight device 8 are stacked in the storage case 5 from the upper side. It has a structure. In this case, the backlight device 8 is provided with a flat light source 10 in which a large number of light emitting diodes are arranged on a substrate below the mounting case 9, and a diffusion plate 11 that diffuses the light of the flat light source 10 above the mounting case 9. Is provided, and the peripheral edge of the lower surface of the flat light source 10 is adhered to the bottom of the storage case 5 by the double-sided tape 4. The liquid crystal display device 7 has its lower surface peripheral edge portion adhered to the upper surface of the backlight device 8 by the double-sided tape 4. A lower case 12 is arranged below the storage case 5. The lower case 12 and the upper case 1 form a device case.
【０００３】[0003]
しかしながら、この従来の液晶表示装置の収納構造では、液晶表示装置７とバ ックライト装置８を積層させて収納する収納ケース５を上ケース１と別に製作し 、この収納ケース５を上ケース１にビス６で取り付けなければならないため、部 品点数が多く、製作コストが高くなるという問題があった。 特に、バックライト装置８は、平面型光源１０および拡散板１１を取付ケース ９に取り付けなければ、収納ケース５内に収納することができないため、取付ケ ース９が必要となり、その分、部品点数が多くなり、製作コストが高くなるとい う問題がある。 この考案の目的は、部品点数を削減し、製作コストを低減できる液晶表示装置 の収納構造を提供することである。 However, in the conventional liquid crystal display device storage structure, a storage case 5 for stacking and storing the liquid crystal display device 7 and the back light device 8 is manufactured separately from the upper case 1, and the storage case 5 is screwed into the upper case 1. Since it had to be attached in 6, there was a problem that the number of parts was large and the manufacturing cost was high. In particular, the backlight device 8 cannot be stored in the storage case 5 unless the flat light source 10 and the diffusion plate 11 are mounted in the mounting case 9, and therefore the mounting case 9 is required. There is a problem that the number of points increases and the manufacturing cost increases. An object of this invention is to provide a housing structure for a liquid crystal display device which can reduce the number of parts and the manufacturing cost.
【０００４】[0004]
この考案は、機器ケースの表面の所定個所に開口部を形成するとともに、この 開口部の縁部と対応する前記機器ケースの内面にほぼ枠状の収納部を一体に形成 し、この収納部の底部側にバックライト装置を収納するとともに、収納部内の開 口部側に液晶表示装置を収納したものである。 According to this invention, an opening is formed at a predetermined position on the surface of the equipment case, and a substantially frame-shaped storage portion is integrally formed on the inner surface of the equipment case corresponding to the edge of the opening. The backlight device is housed on the bottom side, and the liquid crystal display device is housed on the opening side in the housing part.
【０００５】[0005]
この考案によれば、開口部の縁部と対応する機器ケースの内面にほぼ枠状の収 納部を一体に形成したので、従来のような別部材としての収納ケースが不要とな り、その分、部品点数が少なくなり、低価格化を図ることができる。この場合、 収納部の下部にバックライト装置の平面型光源と拡散板が取り付けられる取付部 を形成すれば、従来のような取付ケースが不要となるので、バックライト装置の 部品点数を削減でき、より一層、製作コストを低減することができる。 According to this invention, since the substantially frame-shaped storage part is integrally formed on the inner surface of the device case corresponding to the edge of the opening, the conventional storage case as a separate member is unnecessary. Therefore, the number of parts is reduced, and the cost can be reduced. In this case, if the mounting part to which the flat light source of the backlight device and the diffuser plate are mounted is formed in the lower part of the storage part, the conventional mounting case is not required, so the number of parts of the backlight device can be reduced. The manufacturing cost can be further reduced.
【０００６】[0006]
以下、図１を参照して、この考案の一実施例を説明する。 図１において、２０は機器ケースである。この機器ケース２０は、上ケース２ １と下ケース２２とで構成されている。上ケース２１の所定個所には、表示用の 開口部２３が形成されている。この開口部２３は矩形状の孔であり、その縁部に は上面側が広い段差部２４が形成されている。この開口部２３の縁部、つまり段 差部２４の下面には、ほぼ枠状の収納部２５が開口部２３と対応して一体に形成 されている。収納部２５内には、上から順に、データを表示する液晶表示装置２ ６と、この液晶表示装置２６の裏面（下面）を照明するバックライト装置２７が 積層収納されている。この場合、バックライト装置２７は、発光ダイオードを基 板上に多数配列した平面型光源２８と、この平面型光源２８の光を拡散する拡散 板２９とからなっている。そして、収納部２５の下部内周面には、バックライト 装置２７の平面型光源２８と拡散板２９を取り付けるための鍔状の取付部３０が 突出して形成されている。すなわち、取付部３０の下面には収納凹部３１が設け られ、この収納凹部３１内には平面型光源２８がビス３２により取り付けられて いる。また、取付部３０の上面には拡散板２９が両面テープ３３により接着され ている。この拡散板２７上には液晶表示装置２６が両面テープ３３により接着さ れている。さらに、液晶表示装置２６の上方における開口部２３には透明なガラ ス板３４が嵌め込まれて両面テープ３３により段差部２４に接着されている。 An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, 20 is a device case. The device case 20 is composed of an upper case 21 and a lower case 22. An opening 23 for display is formed at a predetermined portion of the upper case 21. The opening 23 is a rectangular hole, and a step portion 24 having a wide upper surface is formed at the edge of the opening 23. On the edge of the opening 23, that is, on the lower surface of the stepped portion 24, a substantially frame-shaped storage portion 25 is integrally formed in correspondence with the opening 23. A liquid crystal display device 26 that displays data and a backlight device 27 that illuminates the back surface (lower surface) of the liquid crystal display device 26 are stacked and housed in the housing portion 25 in order from the top. In this case, the backlight device 27 includes a flat light source 28 in which a large number of light emitting diodes are arranged on a base plate, and a diffusion plate 29 for diffusing the light of the flat light source 28. A flange-shaped mounting portion 30 for mounting the flat light source 28 of the backlight device 27 and the diffusion plate 29 is formed on the inner peripheral surface of the lower portion of the housing portion 25 so as to project therefrom. That is, a storage recess 31 is provided on the lower surface of the mounting portion 30, and the flat light source 28 is mounted in the storage recess 31 with screws 32. Further, a diffusion plate 29 is adhered to the upper surface of the mounting portion 30 with a double-sided tape 33. The liquid crystal display device 26 is adhered onto the diffusion plate 27 by a double-sided tape 33. Further, a transparent glass plate 34 is fitted in the opening 23 above the liquid crystal display device 26 and adhered to the step portion 24 by a double-sided tape 33.
【０００７】 このような液晶表示装置の収納構造では、上ケース２１に液晶表示装置２６お よびバックライト装置２７を収納する収納部２５を一体に形成したので、従来の ような別部品としての収納ケース５が不要となり、その分、部品点数が少なくな り、製作コストを低減できる。また、収納部２５にはバックライト装置２７の平 面型光源２８および拡散板２９を取り付ける取付部３０が一体に形成されている ので、従来のような取付ケース９が不要となり、これによっても部品点数を少な くすることができ、より一層の低価格化を図ることができる。 また、この収納構造では、開口部２３の縁部に段差部２４が上ケース２１の厚 さ内で形成されているので、開口部２３内に嵌め込まれたガラス板３４の下面に 接近させて液晶表示装置２６を配置することができ、このため段差部２４の厚さ だけ従来のものよりも実装スペースの厚さを薄くでき、しかもバックライト装置 ２７の平面型光源２８が最下部に位置しているので、従来の収納ケース５の底部 の厚さだけ実装スペースを薄くでき、これらにより液晶表示装置２６およびバッ クライト装置２７全体の実装スペースの厚さを薄くすることができ、ひいては電 子機器全体の薄型化を図ることができる。In such a liquid crystal display device storage structure, since the storage portion 25 for storing the liquid crystal display device 26 and the backlight device 27 is integrally formed in the upper case 21, it is possible to store the liquid crystal display device 26 and the backlight device 27 as separate parts. The case 5 is no longer necessary, and the number of parts is reduced accordingly, and the manufacturing cost can be reduced. Further, since the mounting portion 30 for mounting the flat light source 28 and the diffuser plate 29 of the backlight device 27 is integrally formed in the storage portion 25, the conventional mounting case 9 becomes unnecessary, which also contributes to the parts. The number of points can be reduced and the price can be further reduced. Further, in this storage structure, since the step portion 24 is formed at the edge of the opening 23 within the thickness of the upper case 21, the liquid crystal is brought close to the lower surface of the glass plate 34 fitted in the opening 23. Since the display device 26 can be arranged, the thickness of the stepped portion 24 can reduce the thickness of the mounting space as compared with the conventional one, and the flat light source 28 of the backlight device 27 is located at the bottom. Since the mounting space can be reduced by the thickness of the bottom of the conventional storage case 5, the overall mounting space of the liquid crystal display device 26 and the backlight device 27 can be reduced, and by extension, the entire electronic device. Can be made thinner.

以上説明したように、この考案によれば、機器ケースに設けられた開口部の縁 部と対応する機器ケースの内面にほぼ枠状の収納部を一体に形成したので、従来 のような別部材としての収納ケースが不要となり、その分、部品点数が少なくな り、製作コストを低減することができる。 As described above, according to the present invention, since the substantially frame-shaped storage portion is integrally formed on the inner surface of the device case corresponding to the edge of the opening provided in the device case, a separate member as in the prior art is used. Since the storage case is unnecessary, the number of parts is reduced accordingly, and the manufacturing cost can be reduced.
