JP 2004-22358 A

  In the above apparatus, since a large number of operation buttons 15 and 92 are provided in two stages in the portion excluding the opening 8, since these operation buttons are concentrated in a narrow portion, there is a first drawback that is difficult to operate. . In order to eliminate this drawback, the present inventor provided an operation panel on the front surface of the tray, provided operation buttons on the operation panel, and increased the interval between the plurality of operation buttons. Each switch was attached to each operation button. The circuit board is fixed inside the casing, and a flexible wiring group is provided between the connector on the circuit board and each switch.

  However, in the above configuration, since the tray is pulled out and stored thereafter, the flexible wiring group has a second drawback that it is easy to break due to bending. Therefore, the present invention provides an electronic device that can easily operate the operation button and does not have a fear of disconnection due to the flexible wiring group in consideration of such a conventional defect.

  In order to solve the above-mentioned problem, in the present invention of claim 1, the tray, the casing provided with an opening on the front surface so that the tray is pulled out, the operation button provided on the front surface of the tray, and the tray A fixed light guide and a light emitter and a light receiver provided on the casing are provided, and light from the light emitter reaches the light receiver via the light guide according to the operation position of the operation button. It was configured not to reach or reach.

In the present invention of claim 2, the tray is constituted by a tray body and an operation panel, the tray body is fixed to the toilet body so that a disk is placed, and the operation panel is located on the front surface, and the light guide Is fixed inside the operation panel, and operation buttons are provided on the operation panel.
In the present invention of claim 3, the operation button is composed of an operation unit, a main body connected to the operation unit, a projection made of a light-shielding material adjacent to the main unit, and with respect to a hole formed in the operation panel, The operation button was configured to be movable in a linear direction by inserting the main body and the protrusion.
In the present invention of claim 4, the light guide is formed in a substantially inverted U shape, and the linear portion fixed to the operation panel is divided into two so as to form a gap, and when the operation button is not operated, Since the protrusion is not positioned in the gap, the light from the light emitter reaches the light receiver through the light guide and the gap.
In the present invention of claim 5, the light guide is formed in a substantially inverted U shape, and the linear portion fixed to the operation panel is divided into two so as to form a gap, and the operation button is operated. The main body of the operation button moves outside the light guide, and the protrusion of the operation button is positioned in the gap, so that the light from the light emitting body is blocked by the protrusion and does not reach the light receiver.

  Since the operation buttons are also provided on the front surface of the tray as in the configuration of the first aspect, it is possible to widen the interval between the operation buttons, and to prevent crowding in a narrow portion as in the conventional case. As a result, the user can easily operate the operation buttons. Further, since the light emitter and the light receiver are provided on the casing and the operation button and the light guide are provided on the tray, when the tray is pulled out, a flexible wiring group is not required as in the conventional case, and there is no fear of disconnection.

  As in the configuration of the second aspect, the operation button and the light guide are attached to the operation panel fixed to the tray body. As a result, even if the operation button and the light guide fixed to the drawable tray are moved, they are not wired, so there is no need to use a flexible wiring group.

  With the configuration of the third aspect, it is possible to reliably output an on / off signal depending on whether or not the operation button is pushed in a linear direction.

  According to the fourth aspect of the present invention, when the operation button is not operated when the tray is stored, the light receiver can completely sense the light from the light emitter.

  According to the fifth aspect of the present invention, when the operation button is operated when the tray is stored, the light receiver does not completely detect the light from the light emitter. Further, when the operation button is operated, the main body of the operation button moves outside the light guide, so that no external force is applied to the light guide at this time.

  For example, the bottom 5 has a substantially U-shaped cross section (see FIG. 4). The front parts 6 and 7 are provided so as to close the upper opening formed in the bottom part 5. An opening 13 is formed at an appropriate position on the front surface of the casing 4.

  The upper parts 8 and 9 are provided so as to cover the upper part of the bottom part 5. The side portions 10 and 11 are provided so as to cover the side surfaces of the upper portions 8 and 9. The back surface portion 12 is provided so as to cover the back surfaces of the upper portions 8 and 9.

  The display unit 14 includes, for example, a liquid crystal display device or the like, and is configured to be able to stand up as necessary. The button 15 is provided on the front part 6, and the button 16 is provided on the front part 7.

  The tray body 17 is made of, for example, plastic, and a thick portion 18 is formed around the tray body 17 and a disc fixing portion 19 is formed at the center. For example, the disk 20 made of a DVD-ROM or the like is placed on the tray body 17 and fixed by the disk fixing unit 19.

  The operation panel 21 is made of, for example, a metal plate or plastic, and has a substantially inverted L-shaped cross section (see FIG. 5). A fixing portion 22 is formed at an appropriate position of the operation panel 21, and the fixing portion 22 is fixed to the thick portion 18 formed on the tray main body 17 by screws 23.

  As described above, the tray 2 includes the tray body 17 and the operation panel 21. The tray main body 17 is fixed to the tray main body 17 so that the disk 20 is placed and the operation panel 21 is located on the front surface.

  The operation buttons 24a, 24b, 24c, 24d, 24e, 24f, and 24g are provided on the front surface of the operation panel 21 constituting the tray 2 (see FIG. 1).

  The support plate 25 supports the tray body 17, and a spur gear portion (not shown) is formed at the right end. The spur gear portion is configured to mesh with a gear (not shown), and this gear is fixed to a shaft of a motor (not shown).

  As will be described later, when the user operates (presses) the operation button 24c (for eject), an electric signal is input to a microcomputer (not shown). The microcomputer outputs a driving voltage to the motor, and the motor rotates.

  As a result, the support plate 25 moves forward (D1 direction), and the tray 2 also moves forward. In this way, the tray 2 is configured to be pulled out, that is, to advance forward (direction D1) (see FIG. 4).

As shown in FIG. 2, each of the operation buttons 24a to 24g includes, for example, an operation unit 26, a main body 27, a projection 28, and the like. The operation buttons 24a to 24g are formed of, for example, plastic, and the operation unit 26 is circular when viewed from the plane, and is formed into an oval shape when viewed from the side. The main body 27 is connected to the operation unit 26, is formed below the operation unit 26, and has a substantially cylindrical shape.

  The protrusion 28 is formed adjacent to the main body 27 and connected to the main body 27. The protrusion 28 is formed in a substantially rectangular parallelepiped shape. At least the protrusion 28 is made of a light shielding material. If necessary, the entire operation buttons 24a to 24g may be made of a light shielding material.

  In this manner, the main body 27 and the protrusion 28 are inserted into the substantially gourd-shaped hole formed in the operation panel 21. By this insertion, the operation buttons 24a to 24g are configured to be movable in the linear direction (the E1-E2 direction, see FIGS. 3 and 4).

  As shown in FIG. 3, the light guide 29 is made of, for example, acrylic resin and is formed in a substantially inverted U shape. The straight portion of the light guide 29 fixed to the operation panel 21 is divided into two so that a gap 30 is formed.

  That is, the light guide 29 includes a left light guide 31 and a right light guide 32. The straight portion of the left light guide 31 is fixed to the inner surface of the operation panel 21 through an adhesive, for example. The straight portion of the right light guide 32 is fixed to the inner surface of the operation panel 21 via an adhesive, for example.

  In this manner, the light guide 29 is fixed to the tray 2. More specifically, the light guide 29 is fixed inside the operation panel 21, and the operation buttons 24 a to 24 g are provided on the operation panel 21.

  A spring 33 is disposed between the bottom surface of the operation unit 26 constituting the operation buttons 24 a to 24 g and the upper surface of the operation panel 21. As a result, the operation buttons 24a to 24g are always given an upward force (E1 direction).

  In addition, an E-ring 34 is fixed at a proper position of the main body 27 constituting the operation buttons 24a to 24g. As a result, the operation buttons 24a to 24g are always applied with force in the E1 direction, but the upper surface of the E ring 34 and the bottom surface of the left light guide 31 and the bottom surface of the right light guide 32 come into contact with each other. That point becomes the top dead center (see FIG. 3). At this time, the bottom surface of the protrusion 28 is configured to be positioned above the gap 30.

  As shown in FIG. 4, mounting portions 35 and 36 are formed at appropriate positions on the bottom 5 of the casing 4. The circuit board 37 is mounted on the mounting portions 35 and 36 and is fixed by screws (not shown) or the like.

  As shown in FIG. 3, the light emitter 38 is made of, for example, a light emitting diode. The light emitter 38 is configured to be positioned below the lower end of the left light guide 31.

  The light receiver 39 is made of, for example, a photodiode. The light receiver 39 is configured to be positioned below the lower end of the right light guide 32.

  As described above, the casing 4 is provided with the light emitter 38 and the light receiver 39. And according to the operation position of operation button 24a-24g, it is comprised so that the light from the light-emitting body 38 may reach | attain the light-receiving body 39 via the light guide 29, respectively.

  In FIG. 1, for example, the operation button 24a is a button for pause of reproduction. The operation button 24b is a button for stopping reproduction. The operation button 24c is an eject button. The operation button 24d is a fast-forward button. The operation button 24e is a rewind button. The operation button 24f is a button for starting reproduction. The operation button 24g is a button for turning on / off the power.

  Next, the operation of the electronic apparatus 1 will be described with reference to FIGS. First, when the user pushes the operation button 24g (for power on / off) and pushes the operation button 24c (for eject) (see FIG. 1), the tray 2 is pulled out (see FIG. 5).

  Thereafter, when the user places the disk 20 (DVD-ROM or the like) on the tray body 17 and pushes in the tray 2, the original state is obtained (see FIG. 1).

  At this time, since the operation button 24f (for reproduction start) is not operated, the operation button 24f is located at the top dead center (see FIG. 3). As a result, the lower end of the protrusion 28 provided on the operation button 24 f is located above the gap 30.

  As a result, light from the light emitter 38 passes through the left light guide 31 and the gap 30, passes through the right light guide 32, and reaches the light receiver 39. As a result, the photoreceptor 39 outputs a Hi signal to the microcomputer via a conductive portion (not shown) on the circuit board 37. At this time, the microcomputer does not start playback by a built-in program.

  The characteristics of the above operation are summarized. When the operation button 24f is not operated (see FIG. 3), the protrusion 28 is not positioned in the gap 30. As a result, the light from the light emitter 30 reaches the light receiver 39 via the light guide 29 and the gap 30.

  Next, it is assumed that the user operates (presses) the operation button 24f (for reproduction start). At this time, the lower end of the projection 28 provided on the operation button 24f moves downward (E2 direction), and is positioned near or below the lower end of the gap 30.

  Thereby, the light from the light emitter 38 passes through the left light guide 31 and is blocked by the protrusion 28. Therefore, the light from the light emitter 38 does not reach the light receiver 39.

  As a result, the photoreceptor 39 switches the output of the Hi signal and outputs the Lo signal to the microcomputer via a conductive portion (not shown) on the circuit board 37. At this time, the microcomputer starts a reproducing operation by a built-in program.

  For example, the microcomputer causes the display unit 14 to display a predetermined video according to the video data recorded on the disk 20. Further, the microcomputer causes left and right speakers (not shown) to output a predetermined sound according to the sound data recorded on the disk 20. In this way, the reproduction operation is performed.

  When the operation button 24f is pressed, the main body 27 of the operation button 24f moves outside the light guide 29 (see FIG. 4). At this time, the protrusion 28 of the operation button 24 f moves in the gap 30.

  The characteristics of the above operation are summarized. When the operation button 24 f is operated, the main body 27 of the operation button 24 f moves outside the light guide 29. At this time, the protrusion 28 of the operation button 24 f is positioned in the gap 30, so that light from the light emitter 38 is blocked by the protrusion 28 and does not reach the light receiver 39.
