Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.
1 is a schematic side sectional view of a remote control device according to an embodiment of the present invention, FIG. 2 is a schematic side view of the remote control device, and FIG. 3 is a schematic diagram of the remote control device viewed from the operation surface side. 4 is a sectional view taken along line IV-IV in FIG.

  In the figure, reference numeral 1 denotes a housing constituting a bar-type remote control device, which is made of an elastic member such as rubber. The housing 1 has a substantially rectangular parallelepiped shape with curved ridge lines, and includes an upper half 10 on the operation surface side and a lower half 11 on the bottom side.

  The lower half body 11 has a substantially rectangular lower surface portion 11a, and support pillars 2 and 2 for supporting the frame body 3 having a substantially rectangular periphery project from the four corners of the lower surface portion 11a. At appropriate portions of the frame body 3 supported by the support pillars 2 and 2, a flange portion 30 protruding to the upper half body 10 side is formed. The peripheral portion of the circuit board 40 having a smaller size than that of the frame body 3 is locked to the flange portion 30, and the circuit board 40 is sandwiched between the frame body 3 and the flange portion 30.

  The circuit board 40 includes a transmission unit 41 that transmits an operation signal for remotely operating an external device, for example, a liquid crystal display, a liquid crystal display panel 42, and a control circuit 43 that controls transmission of the transmission unit 41. Arranged in order from the front to the back.

  The liquid crystal display panel 42 displays soft keys A and B for remotely operating the external device at predetermined positions. For example, as shown in FIG. 3, “view”, “record”, and “dubbing” soft keys A, a cross-shaped soft key B, or soft keys such as “play” and “stop” (not shown) are displayed. The display on the liquid crystal display panel 42 is controlled by the control circuit 43.

  The upper half 10 of the housing 1 is formed with a translucent display window 10c that transmits light from the liquid crystal display panel 42 at a substantially central portion on the operation surface side. The translucent display window 10c is made of a colorless and transparent resin, and has a shape and dimensions necessary for displaying the soft keys A and B displayed at predetermined positions on the liquid crystal display panel 42 to the outside.

FIG. 5 is an enlarged schematic side sectional view of the translucent display window 10 c and the liquid crystal display panel 42.
Inside the translucent display window 10c, a capacitive touch panel 44 for detecting the operation of the soft keys A and B displayed on the liquid crystal display panel 42 is disposed.
The capacitive touch panel 44 includes a plurality of ITO (Indium Tin Oxide) transparent electrodes on the inner surface of the translucent display window 10c so as to correspond to the portions of the liquid crystal panel on which the soft keys A and B are displayed. Yes. The ITO transparent electrode has a circular shape with a smaller area than a human finger and has a specific capacitance. The capacitance of the ITO transparent electrode changes when an object such as a human finger touches the translucent display window 10c.
Each ITO transparent electrode of the touch panel 44 is connected to an oscillation circuit (not shown) via a wire 46 and a connector 45 disposed on the circuit board 40. The oscillation circuit gives a signal having a specific frequency determined by the capacitance of the ITO transparent electrode to the control circuit 43.

  The control circuit 43 includes a CPU, a ROM, a RAM, an input unit, and the like. The input unit is configured to receive a signal supplied from the oscillation circuit. The ROM identifies the ITO transparent electrode whose capacitance has changed, that is, the operated part of the touch panel 44 based on the frequency of the signal supplied from the oscillation circuit, and the remote operation signal data corresponding to the identified part. A program to be given to the transmission unit 41 is stored. The CPU executes a process related to the remote operation by reading and executing the program stored in the ROM.

  The transmission unit 41 includes a light emitting diode that transmits an infrared remote operation signal corresponding to the data given from the control circuit 43. The housing 1 has a transmission window 12 that transmits an infrared remote operation signal at a portion facing the transmission unit 41.

Similarly, the lower half body 11 forms four linear thin portions 11b and 11b along the four sides of the lower surface portion 11a.
The thickness of the thin portion has a width necessary for maintaining the strength to such an extent that the thin portion is not broken by a drop impact.

  In the remote control device configured as described above, the case 1 can be prevented from being damaged by a drop impact by forming the case 1 with an elastic member.

  Further, since the casing 1 absorbs the impact of the drop, it is possible to prevent the liquid crystal display panel 42, the control circuit 43, the transmission unit 41, and the like housed in the casing 1 from being damaged by the impact of the drop.

  Further, since the support pillars 2 and 2 support the frame body 3 holding the circuit board 40 so that the circuit board 40 and the housing 1 are separated from each other, the housing 1 is bent by the impact of dropping. Even in this case, there is no possibility that the transmission unit 41, the liquid crystal display panel 42, the control circuit 43, etc. disposed on the circuit board 40 collide with the casing 1 and are damaged.

  Furthermore, since the hollow buffer convex portion 5 made of an elastic member and provided with the air holes 5a surrounds the translucent display window 10c, the remote control device is dropped from the translucent display window 10c side. However, the impact of the fall is absorbed by the buffer convex portion 5. Therefore, it is possible to prevent the translucent display window 10c from being damaged by a drop impact.

  Furthermore, since the liquid crystal display panel 42 and the touch panel 44 are housed in the housing 1, it is excellent in waterproofing and drip-proofing, and a remote control device is used in a place where water drops are likely to be applied such as a bathroom or a kitchen. can do.

Furthermore, as compared with a case that does not include the thin-walled portions 10b,..., 10b, 11b, 11b, the case 1 is easy to bend due to a drop impact and absorbs the shock more effectively. It is possible to prevent the transmitter 41 disposed on the substrate 40 from being damaged.
In particular, with respect to the impact from the front side of the casing 1, that is, the transmission unit 41 side, the thin-walled portions 10b and 11b formed mainly on the front side of the upper half body 10 and the lower half body 11 are bent, and the impact of the drop is caused. Can be absorbed.
Similarly, for the impact from the rear side of the housing 1, the thin-walled portions 10b and 11b formed mainly on the rear side of the upper half body 10 and the lower half body 11 are bent to absorb the impact of the drop. Can do.
In response to a drop impact from the bottom side of the housing 1, the thin-walled portions 11 b and 11 b formed mainly in the lower half 11 are bent, and the drop impact can be absorbed.

  Furthermore, since the housing 1 has thin portions 10b,..., 10b, 11b, and 11b that absorb shocks on the inner surface, the design can be designed more freely than a remote control device that has a thin portion on the outer surface. A design having a high degree and higher creativity can be applied to the housing 1.

  In addition, although it has comprised so that a buffer convex part may surround the translucent display window, you may provide a buffer convex part in the other site | part of a housing | casing. The shock applied to the part as well as the translucent display window can be more effectively absorbed by the buffer convex portion.

  Moreover, although the rubber | casing housing | casing was demonstrated, if it is a member which has elasticity, it will not be limited to this.

  Furthermore, although the entire casing is made of an elastic member, a part of the casing may be made of an elastic member.

  Furthermore, although the thin wall portion is formed on the inner surface, the housing may be formed on the outer surface.

  Furthermore, although the capacitive touch panel has been described, the present invention is not limited to this as long as the operation of the soft key displayed on the liquid crystal display panel can be detected.

  Furthermore, although a liquid crystal display panel for displaying soft keys is provided, other display panels such as an organic EL display panel may be provided as long as the soft keys can be displayed.
