Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a remote control device, in which an infrared shielding member slidably attached to the front of an infrared light emitting element prevents infrared rays from being irradiated accidentally. This is how it was done.

(Problems to be solved by conventional technology and ideas) Remote control devices, which are often used as remote control devices for various electrical devices such as televisions, videos, and air conditioners, emit infrared rays by operating the operation button provided on the main body case. A known remote control device of this type is provided with locking means for the operation buttons to prevent erroneous operation of the device. However, since this kind of conventional locking means is an electric means, it has a complicated structure and has problems such as high cost.

Therefore, an object of the present invention is to provide a remote control device that can prevent erroneous irradiation of infrared rays by simple means.

(Means for Solving the Problems) For this purpose, the present invention provides an infrared shielding member 6 on the front part of the infrared light emitting element 4 provided in the main body case 2.
is slidably mounted, and the infrared shielding member 6 is slid within the width of the main body case 2 to open and close the front portion of the infrared light emitting element 4.

(Function) By configuring the shielding member 6 in this way,
When not in use, this is covered over the front of the light emitting element 4, and even if the operation button 3 is operated incorrectly, the infrared rays are blocked by this to prevent the device from being operated erroneously.
Furthermore, the infrared light emitting section 4 is prevented from being damaged by external force. Furthermore, by making the shielding member 6 slidable within the width of the main body case 2, opening and closing operations are easy, and the fragile shielding member 6 can be removed from the main body case 2.
It will not protrude outside and be damaged by colliding with objects, etc., and can be configured compactly.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a remote control device according to the present invention, and this remote control device 1 consists of a thin box-shaped main body case 2 consisting of an upper case 2a and a lower case 2b, and a plurality of operation buttons 3 are provided on the top surface of the main body case 2. Individually arranged. Reference numeral 4 denotes an infrared light emitting element disposed inside the main body case 2, which is provided on one side of the front wall of the main body case 2, and emits infrared light forward when the operation button 3 is operated.

Reference numeral 5 denotes a protective cover plate for the light emitting element 4 mounted on the front wall of the main body case 2 at the front of the light emitting element 4, and is made of a transparent material through which infrared rays can pass. Reference numeral 6 denotes a plate-shaped infrared shielding member, which is attached to the front wall of the main body case 2 so as to be slidable in the horizontal direction, and by sliding in this direction, the front part of the cover plate 5 is opened and closed ( (See Figure 2 a, b). This shielding member 6 slides within the width range of the main body case 2 so as not to protrude from the main body case 2. This shielding member 6 prevents infrared rays emitted from the light emitting element 4 from being irradiated outside the main body case 2 due to erroneous operation of the operation button 3, thereby preventing erroneous operation of the device.
It is made of opaque synthetic resin and metal plates similar to electromagnetic shielding material to shield infrared rays.

The remote control device 1 has the above-mentioned configuration, and if the operation button 3 is operated with the shielding member 6 moved to the side of the cover plate 5 and opened, infrared rays can be transmitted through the cover plate 5 to devices such as televisions and videos. The device is then irradiated to remotely control the device.

When the operation button 3 is not operated or when the remote control device 1 is stored, the shielding member 6 can be slid to cover the front part of the cover plate 5.
Even if the operation button 3 is operated incorrectly, the infrared rays will be blocked by the shielding member 6.
Since the device is shielded by the device, it cannot be accidentally operated, and it can perform the so-called channel lock function. In addition, this type of infrared rays has strong directionality in order to extend its reach, but if the outer surface of the cover plate 5 is damaged, such as by being hit by an object, the infrared rays will be scattered and its directivity will decrease. ,
Although the reach distance is shortened and the performance is likely to deteriorate, by configuring the shielding member 6 as described above, it is possible to prevent the cover plate 5 from being damaged and the directivity of the infrared rays from decreasing.

The present invention can be further modified in various designs. For example, as shown in FIGS. 3a to 3c, in the case of a removable remote control device 31 such as a television 30, a shielding member 32 of the light emitting element 4 may be attached to the side surface of the detachable remote control device 31. By attaching the shielding member 32 so that it can freely slide in the vertical direction and arranging the operating section 32a on the front side, it is possible to open and close the shielding member 32 even when it is attached to the mounting section 33 of the television 30. The channel lock of the television 30 can be performed by a suitable means, and as described above, various shapes and structures of the shielding member and various attachment/detachment means can be considered.

(Effect of the invention) As explained above, the remote control device according to the invention has an infrared shielding member 6 in front of the infrared light emitting element 4.
is slidably attached, and the infrared shielding member 6 is slid within the width of the main body case 2 to open and close the front part of the infrared light emitting element 4. By covering the front part of the infrared light emitting element 4 with the shielding member 6, even if the operation button 3 is operated incorrectly, the infrared rays are irradiated outside the main body case 2 to prevent the electrical equipment from being operated by mistake. In addition, the fragile shielding member 6 will not protrude outside the main body case 2 and be damaged by colliding with equipment, etc., and the structure is simple and compact, and furthermore, the infrared light emitting element can be activated by external force. 4 from being damaged, thereby preventing deterioration of performance.・
