  FIG. 2 is a perspective view showing a form of a remote control device when the television receiver is remotely operated. FIG. 3 is a perspective view showing the form of the remote control device when inputting character information and position information. The remote control device 10 is used in the form of FIG. 2 when remotely operating the television receiver. When character information or position information is input, it is used in the form shown in FIG.

  As shown in FIG. 2, the housing 17 forms a space inside and accommodates the components shown in FIG. The casing 17 has a shape having a rectangular operation surface in which a pair of opposite sides is longer than the other opposite sides. The remote control device 10 of the present invention has two operation surfaces, and the surface on which the operation keys 11 are arranged as shown in FIG. 2 is a first operation surface 17a, and the keyboard 16 and A surface on which the pointing device 15 is arranged is a second operation surface 17b.

  The first operation surface 17a is disposed above the second operation surface 17b so as to be openable and closable in the bb direction in the figure using a rotation shaft. Further, when the first operation surface 17a is opened, the first operation surface 17a is held at a predetermined angle with respect to the second operation surface 17b. Specifically, when the first operation surface is opened with the rotation axis as the center as shown in FIG. 3, the first operation surface 17a is given a biasing force by, for example, a spring (fixing means) and the second operation surface 17a The operation surface 17b is held at a predetermined angle. Hereinafter, as an example, a mechanism for fixing the first operation surface 17a at a predetermined angle will be described.

  FIG. 4 is a cross-sectional view of the remote controller when inputting character information and position information. From the figure, the first operation surface 17a and the second operation surface 17b are connected to be rotatable counterclockwise in the figure using a rotation shaft 19. In addition, a spring (torsion spring) is disposed on the rotation shaft 19 with the center of the cross section directed in the axial direction of the rotation shaft 19. The spring 20 has end pieces 20a and 20b projecting from both ends, and the elastic force of the spring 20 applies a biasing force counterclockwise in the figure by the end pieces 20a and 20b. At this time, the end piece 20a of the spring 20 is connected to the first operation surface 17a. The end piece 20b of the spring 20 is connected to the second operation surface 17b.

  Thereby, when inputting the character information and the position information, when the first operation surface 17 a is opened, the first operation surface 17 a is rotated counterclockwise in the figure by the elastic force of the spring 20. At this time, the first operation surface 17a is connected to the second operation surface 17b through the rotary shaft 19 so as to open up to a predetermined angle (α in the figure), and is not further opened. . Therefore, after the first operating surface 17 a is opened to a predetermined angle with respect to the second operating surface 17 b by the elastic force of the spring 20, the first operating surface 17 a does not open more than that angle (α in the figure), and half of the elastic force of the spring 20 is applied. Only the clockwise biasing force acts on the first operation surface 17a. Therefore, the first operation surface 17a is held at a predetermined angle by the spring 20. Accordingly, the user displays the second operation surface 17b and operates the keyboard 16 and the pointing device 15.

  The first operation surface 17a is formed in a concave portion having an opening on the lower side, and has a rectangular shape in which the cross section is longer than a pair of opposite sides. Moreover, it is a shape which has the hollow convex part 17a1 with thickness near the center, and the flat surfaces 17a2 and 17a3 whose thickness is thinner than the convex part 17a1 at both ends of the convex part 17a1. A pointing device 15 disposed on the second operation surface 17b is accommodated below the convex portion 17a1.

  On the first operation surface 17a, the operation keys 11 are arranged so that the longer opposite side is arranged in the vertical direction. Specifically, the channel key 11a for switching the channel of the television receiver and the power key 11b are arranged on the first operation surface 17a on the plane 17a2. Further, on the first operation surface 17a, a menu key 11c for operating icons on the menu screen and switching the screen is arranged on the plane 17a3. As a result, when used, it is used with the plane 17a3 on which the menu key 11c is arranged facing down.

  The second operation surface 17b is a rectangle whose cross section is longer in a pair of opposite sides than the other opposite sides, and accommodates each component shown in FIG. Moreover, it is the shape which has the accommodating part 17b1 with a large thickness, and the planes 17b2 and 17b3 which are thin with respect to the accommodating part 17b1. The second operation surface 17b is arranged so that the operation part of the pointing device 15 protrudes from the housing part 17b1. Moreover, the battery 100 and the transmission unit 14 which will be described later are accommodated inside the accommodating portion 17b1. Therefore, an opening for taking in and out the battery 100 is formed on the side surface of the housing portion 17b1, and is normally shielded by the lid 17b4. The second operation surface 17b has keyboards 16 and 16 arranged on flat surfaces 17b2 and 17b3 which are both thin surfaces.

  In addition, the keys of the keyboards 16 and 16 are arranged on the second operation surface 17b so that the longer opposite side is arranged in the horizontal direction. Specifically, the keyboards 16 and 16 are arranged on the planes 17b2 and 17b3 on both sides of the pointing device 15 as the center. Thereby, the keyboards 16 and 16 are operated by holding the planes 17b2 and 17b3 on both sides of the second operation surface 17b with the left and right hands. Further, when the pointing device 15 is operated, for example, the pointing device 15 can be operated by extending the thumb with both hands holding the planes 17b2 and 17b3 with the thumb facing upward.

(1-2) Internal Arrangement Configuration of Remote Control Device FIG. 5 is a cross-sectional view of the remote control device 10. As shown in the figure, the remote control device 10 arranges the control board 12 in the same thickness direction on the bottom surface in the housing 17 and arranges the keyboard 16 above the control board 12. Further, the battery 100 is disposed in the accommodating portion 17b1 of the second operation surface 17b so that the thickness direction is the same, and the transmission unit 14 is disposed beside the battery 100, and the pointing device 15 is disposed above the battery 100. Deploy. Furthermore, above the keyboard 16, the operation keys 11 arranged on the first operation surface 17a are divided into planes 17a2 and 17a3.

  Further, the first operation surface 17 a and the second operation surface 17 b are configured to be linked to the pressing operation via the transmission piece 13. Specifically, a transmission piece 13 that protrudes by a predetermined length is formed on the surface of the operation key 11 that does not protrude from the first operation surface 17a. Therefore, when the first operation surface 17a is closed above the second operation surface 17b so as to be centered on the rotation axis, the tip of the transmission piece 13 protruding from the operation key 11 is any key of the keyboard 16. Is disposed above. Thereby, when each key of the operation key 11 is pressed, the transmission piece 13 presses each key of the lower keyboard 16 in conjunction therewith. Thereby, the pressing operation of the operation key 11 is transmitted to the control board 12. Therefore, the operation switching is executed as follows.

  That is, the switching of the operation of the operation key 11 and the keyboard 16 is switched via the switching piece 18. Specifically, a switching piece 18 that protrudes from the back side is disposed on the back side of the first operation surface 17a where the operation keys do not protrude. When the first operation surface 17a is disposed above the second operation surface 17b, a switching key 16a, which is a key of the keyboard 16, is disposed below the switching piece 18. For this reason, when the first operation surface 17a is disposed above the second operation surface 17b, the switching piece 18 presses the switching key. Thereby, on the control board 12, the command that receives the pressing operation of the switching key 16a and outputs it to the transmission unit 14 is switched from the command when the keyboard 16 is operated to the command when the operation key is operated. Thereby, the radio wave transmitted from the transmission unit 14 is obtained by operating the operation key 11.

  At this time, if there are a plurality of switching pieces 18 protruding from the first operation surface 17a, switching between the operation keys 16 and the keyboard 16 is performed only when the plurality of switching pieces 18 are pressed. That is, only when a plurality of operation keys 16 are pressed, operation switching is executed. Therefore, it is possible to reduce the probability of preventing the switch key from being erroneously operated with the first operation surface 17a opened.
