[0006] Problems that the invention will solve

[0007] However, if the display unit is arranged in the width direction relative to the attenuator device, there is a problem that the width dimension of the unit including the attenuator device and the display unit becomes larger. If the width dimension of each unit is large, when a plurality of units are arranged in the width direction, the width dimension of the entire operation panel becomes very large, which is not preferable.

[0020] Below, refer to Figures 1 to 5 , an embodiment of the present invention is described.

[0021] The operation panel of this embodiment is used as a parameter adjustment device for mixing a plurality of mixers, for example. Figures 1 to 3 As shown, the operation panel 1 includes a base member 2 , a fader device 3 disposed on the base member 2 , and a display unit 4 .

[0022] The attenuator device 3 includes an attenuator body 31 and a moving body 32. The moving body 32 is provided so as to be able to move linearly relative to the attenuator body 31. The attenuator device 3 is a device for adjusting parameters such as volume and tone by moving the moving body 32. The moving body 32 protrudes from the inside of the attenuator body 31 to the outside. The protruding direction ( Figures 2 to 4 The upward direction in the figure) is orthogonal to the moving direction of the moving body 32.

[0023] Hereinafter, the attenuator device 3 according to the present embodiment will be described in detail.

[0024] The attenuator body 31 of the present embodiment is formed into a rectangular parallelepiped. On the facing surface 31a of the attenuator body 31 facing the base member 2 described later, there is an elongated opening portion 33 extending in the moving direction of the moving body 32. The moving body 32 protrudes from the inside to the outside of the attenuator body 31 through the opening portion 33. The facing surface 31a of the attenuator body 31 is formed into an elongated rectangle with the moving direction of the moving body 32 as the long side and the direction orthogonal to the moving direction of the moving body 32 and the protruding direction (hereinafter referred to as the width direction) as the short side. The attenuator body 31 is formed into a shape that is longer in the moving direction of the moving body 32 and shorter in the width direction (width dimension), that is, an elongated shape extending in the moving direction of the moving body 32.

[0025] The attenuator body 31 has two protruding portions 34 (supporting portions) protruding from both ends of the facing surface 31a in the width direction in the protruding direction of the moving body 32. The two protruding portions 34 extend in the moving direction of the moving body 32. Each protruding portion 34 is formed in an elongated shape extending in the moving direction of the moving body 32. The length of the protruding portion 34 in the moving direction of the moving body 32 can be as follows: Figure 2 As illustrated, the length is equivalent to that of the attenuator main body 31 , but may be shorter than the length of the attenuator main body 31 , for example.

[0026] The moving body 32 is formed in a plate shape with the width direction being the thickness direction. A knob 35 is detachably mounted on the front end portion of the moving body 32 in the protruding direction. The knob 35 is a portion that is pinched by the operator of the operation panel 1 with fingers in order to move the moving body 32, and is mounted so as to cover the front end portion of the moving body 32. The knob 35 is formed in a block shape whose width dimension is larger than the width dimension of the moving body 32.

[0027] The operation panel 1 of this embodiment has a plurality (three in the example shown) of the above-mentioned attenuator devices 3. The plurality of attenuator devices 3 are arranged at intervals in the width direction. Alternatively, the plurality of attenuator devices 3 may be arranged without intervals in the width direction, for example.

[0028] The display unit 4 displays a state corresponding to the position of the moving body 32 of the attenuator device 3. The display unit 4 displays the magnitude of the volume actually output from the speaker or the like, based on the volume level set according to the position of the moving body 32, for example.

[0029] like Figure 2 , 4As shown in FIGS. 5 and 6 , the display unit 4 is formed in an elongated shape extending in the moving direction of the moving body 32, similarly to the attenuator main body 31. The display unit 4 includes an elongated strip-shaped circuit substrate 41, a light emitting element 42 mounted on a mounting surface 41a of the circuit substrate 41, and a light guide member 43 disposed on the mounting surface 41a of the circuit substrate 41 and covering the light emitting element 42.

[0030] The light emitting element 42 is, for example, a chip-shaped light emitting diode (LED). A plurality of light emitting elements 42 are mounted on the mounting surface 41a of the circuit substrate 41. The plurality of light emitting elements 42 are arranged at intervals in the longitudinal direction of the circuit substrate 41. In addition, a plurality of light emitting elements 42 (two in the example shown) are also arranged at intervals in the width direction of the circuit substrate 41 corresponding to the width direction of the attenuator body 31.

[0031] The light guide member 43 guides the light of the light emitting element 42 in a direction away from the mounting surface 41a of the circuit substrate 41 (in the thickness direction of the circuit substrate 41). The light guide member 43 has a light-transmitting portion 44 through which light is transmitted and a light-shielding portion 45 through which light is not transmitted. The light-transmitting portion 44 is located at a position where the light emitting element 42 is arranged between the mounting surface 41a of the circuit substrate 41. The light guide member 43 has a number of light-transmitting portions 44 corresponding to the number of light emitting elements 42. A plurality of light-transmitting portions 44 are arranged at positions corresponding to the plurality of light emitting elements 42, respectively. That is, the plurality of light-transmitting portions 44 are arranged at intervals in the length direction and the width direction of the circuit substrate 41, similarly to the plurality of light emitting elements 42. The light-shielding portion 45 is provided so as to surround each light-transmitting portion 44 and the light emitting element 42 corresponding thereto, respectively, when viewed from the mounting surface 41a side of the circuit substrate 41. The light guide member 43 configured in this way guides the light of each light emitting element 42 in a direction away from the mounting surface 41a of the circuit substrate 41 while suppressing the mixing of the light of the adjacent light emitting elements 42.

[0032] In the display unit 4 of the present embodiment, the interposed portion between the plurality of light-transmitting portions 44 and the light-shielding portion 45 disposed adjacent to the light-transmitting portions 44 is a convex portion 47 that protrudes in a direction away from the mounting surface 41a of the circuit board 41 from the surrounding portion (the base portion 46 of the display unit 4) of the light-shielding portion 45 surrounding the plurality of light-transmitting portions 44. Figure 2 , 5 In the embodiment, the convex portion 47 is divided into two in the longitudinal direction of the display portion 4, but, for example, it may not be divided.

[0033] like Figures 1 to 3 As shown, the operation panel 1 of this embodiment has display units 4 corresponding to the number of attenuator devices 3 (three in the example shown). Each display unit 4 displays a state corresponding to the position of the movable body 32 of the corresponding attenuator device 3. Each display unit 4 is arranged adjacent to the movable body 32 of the corresponding attenuator device 3 in the width direction. Figure 3 In the figure, each display unit 4 is arranged on the right side of the moving body 32 of the corresponding attenuator device 3.

[0034] The base member 2 is formed in a plate shape with the protruding direction of the moving body 32 as the thickness direction. The base member 2 has an insertion hole 21 and an exposure hole 22 penetrating the base member 2 in the thickness direction.

[0035] The insertion hole 21 extends in the moving direction of the moving body 32. The moving body 32 of the attenuator device 3 passes through the insertion hole 21. The base member 2 has the insertion holes 21 corresponding in number (three in the example shown) to the attenuator device 3. The plurality of insertion holes 21 are arranged at intervals in the width direction orthogonal to the thickness direction of the base member 2 and the length direction of the insertion holes 21.

[0036] The exposure hole 22 extends in the moving direction of the movable body 32 similarly to the insertion hole 21. The exposure hole 22 is a hole for allowing light from the display unit 4 (light emitting element 42) to pass from one side of the base member 2 to the other side in the thickness direction. Figure 2 In the embodiment, the exposure hole 22 is divided into two in the longitudinal direction of the exposure hole 22 in a manner corresponding to the convex portion 47 of the display unit 4 divided into two, but it may not be divided, for example. The base member 2 has the exposure holes 22 corresponding to the number (three in the example shown) of the display unit 4. The plurality of exposure holes 22 are arranged alternately with the insertion holes 21 in the width direction.

[0037] The plurality of attenuator devices 3 are respectively arranged on the surface of the base member 2 facing one side in the thickness direction (hereinafter referred to as the back surface 2b). The attenuator body 31 of the attenuator device 3 is fixed to the base member 2 by screwing or the like in a state where the facing surface 31a thereof faces the back surface 2b of the base member 2. The plurality of attenuator devices 3 mounted on the base member 2 are arranged in the width direction along the back surface 2b of the base member 2.

[0038] When the attenuator device 3 is mounted on the base member 2, the moving body 32 passes through the insertion hole 21 of the base member 2, and the front end of the moving body 32 is located on the front side 2a of the base member 2, which is opposite to the back side 2b. The knob 35 is mounted on the front end of the moving body 32 so as to be located on the front side 2a of the base member 2. Thus, the operator of the operation panel 1 can contact the moving body 32 of the attenuator device 3 from the front side 2a of the base member 2 to move it. At this time, the moving body 32 moves along the front side 2a (or the back side 2b) of the base member 2.

[0039] The plurality of display units 4 are respectively arranged on the back side 2b of the base member 2 in the same manner as the attenuator device 3. In this state, the display unit 4 is exposed to the front side 2a of the base member 2 through the exposure hole 22 of the base member 2. Figure 4 As shown in FIG. 1 , the display unit 4 of the present embodiment is arranged such that the mounting surface 41a of the circuit substrate 41 faces the back surface 2b of the base member 2, and the light emitting element 42 and the light-transmitting portion 44 of the light-guiding member 43 are exposed to the front surface 2a side of the base member 2 through the exposure hole 22 of the base member 2. In addition, the convex portion 47 of the light-guiding member 43 including the plurality of light-transmitting portions 44 is inserted into the exposure hole 22 from the back surface 2b side of the base member 2. Thus, the operator of the operation panel 1 can visually check the display unit 4 from the front surface 2a side of the base member 2. In the state where the convex portion 47 of the light-guiding member 43 is inserted into the exposure hole 22, the base portion 46 of the light-guiding member 43 contacts the back surface 2b of the base member 2.

[0040] like Figures 2 to 4 As shown in the figure, the display unit 4 arranged on the back side 2b of the base member 2 is sandwiched between the base member 2 and the attenuator body 31, and is fixed to the base member 2. The display unit 4 sandwiched between the base member 2 and the attenuator body 31 extends in the moving direction of the moving body 32, and is supported by the attenuator body 31 extending in the moving direction of the moving body 32. Here, each display unit 4 is arranged adjacent to the moving body 32 of the corresponding attenuator device 3 in the width direction as described above. Therefore, each display unit 4 is supported by the protruding portion 34 located at the end of the corresponding attenuator body 31 in the width direction. The following specifically describes the method of sandwiching the display unit 4 between the base member 2 and the attenuator body 31.

[0041] The first display unit 4A disposed between the movable bodies 32 of the two adjacent attenuator devices 3 among the plurality of display units 4 is sandwiched between the two adjacent attenuator bodies 31 and the base member 2 in the width direction. Specifically, both end portions of the circuit substrate 41 of the first display unit 4A in the width direction are supported by the protruding portions 34 of the two adjacent attenuator bodies 31 in the width direction.

[0042] The end portion ( Figure 3 The second display portion 4B (the right end in FIG. 1 ) is sandwiched between the end portion ( Figure 3The attenuator body 31E of the attenuator device 3E at the right end in the arrangement direction and the support member 5 are fixed to the side surface 31b of the attenuator body 31E (hereinafter referred to as the attenuator body 31E at the end) arranged at the end in the arrangement direction, which is opposite to the adjacent other attenuator body 31. Thus, the attenuator body 31E at the end and the support member 5 are arranged in the arrangement direction of the plurality of attenuator devices 3. The support member 5 is fixed to the attenuator body 31E at the end so that the first end of the circuit substrate 41 of the second display unit 4B in the arrangement direction is supported by the protruding portion 34 of the attenuator body 31E at the end, and the portion of the circuit substrate 41 extending from the side surface 31b of the attenuator body 31E at the end is supported by the support member 5.

[0043] exist Figure 2 In the embodiment, the length of the support member 5 in the moving direction of the moving body 32 is shorter than the length of the protruding portion 34 of the attenuator body 31E at the end and the display unit 4, but may be equal to these lengths, for example. In addition, a plurality of support members 5 fixed to the side surface 31b of the attenuator body 31E at the end may be arranged in the moving direction of the moving body 32, for example. The support member 5 may be a relatively hard member such as metal, but in the present embodiment, it is an elastic member having elasticity such as sponge.

[0044] The operation panel 1 of the present embodiment further includes a buffer member 6 interposed between the attenuator body 31 and the display unit 4. The buffer member 6 is an elastic member having elasticity such as a sponge. In the present embodiment, the buffer member 6 is interposed between the protruding portion 34 of the attenuator body 31 and the circuit substrate 41 of the display unit 4. The buffer member 6 is formed in an elongated shape extending in the moving direction of the moving body 32, similarly to the protruding portion 34 and the circuit substrate 41. The buffer member 6 may be fixed to either the protruding portion 34 or the circuit substrate 41 (display unit 4) by bonding or the like, for example.

[0045] As described above, in the operation panel 1 of the present embodiment, the display unit 4 is sandwiched between the base member 2 and the attenuator body 31. Therefore, compared with the case where the display unit 4 and the attenuator device 3 are arranged in the width direction, the width dimension of the unit including the attenuator device 3 and the display unit 4 corresponding thereto can be suppressed to be smaller. Therefore, even if a plurality of units are arranged in the width direction, the width dimension of the entire operation panel 1 can be suppressed to be smaller.

[0046] In the operation panel 1 of this embodiment, the display unit 4 and the protruding portion 34 of the attenuator body 31 supporting the display unit 4 extend in the moving direction of the moving body 32. Thus, the display unit 4 extending in the moving direction of the moving body 32 can be stably supported by the protruding portion 34 of the attenuator body 31.

[0047] In addition, in the operation panel 1 of the present embodiment, the first display unit 4A is sandwiched between two adjacent attenuator bodies 31 and the base member 2. Thus, even if the size of the portion (protruding portion 34) supporting the first display unit 4A in the same attenuator body 31 is smaller than the first display unit 4A, the first display unit 4A can be stably sandwiched between the base member 2 by the two adjacent attenuator bodies 31. In the present embodiment, the width dimension of the protruding portion 34 of the attenuator body 31 supporting the first display unit 4A is smaller than the width dimension of the first display unit 4A, but by supporting both ends of the first display unit 4A in the width direction by the protruding portions 34 of the two attenuator bodies 31, the first display unit 4A can be stably sandwiched between the two attenuator bodies 31 and the base member 2.

[0048] In addition, in the operation panel 1 of the present embodiment, the second display portion 4B is sandwiched between the attenuator body 31E at the end, the support member 5 fixed thereto, and the base member 2. Thus, even if the size of the portion (protruding portion 34) supporting the second display portion 4B in the attenuator body 31E at the end is smaller than the second display portion 4B, the second display portion 4B can be stably supported by the attenuator body 31E at the end and the support member 5. Therefore, the second display portion 4B can be stably sandwiched between the attenuator body 31E at the end and the base member 2.

[0049] In addition, in the operation panel 1 of the present embodiment, the buffer member 6 having elasticity is interposed between the attenuator body 31 and the display unit 4. Therefore, the buffer member 6 is interposed between the attenuator body 31 and the display unit 4 and is elastically compressed and deformed, thereby being able to reliably fill the gap between the attenuator body 31 and the display unit 4. Therefore, even if the dimensional accuracy of the display unit 4 (particularly the dimensional accuracy of the display unit 4 in the direction of holding the display unit 4) is not high, the display unit 4 can be reliably interposed between the base member 2 and the attenuator body 31.

[0050] In addition, in the operation panel 1 of the present embodiment, since the supporting member 5 is an elastic member such as sponge, even if the position accuracy of the supporting member 5 relative to the attenuator body 31E at the end is low, the second display unit 4B can be reliably supported by both the attenuator body 31E at the end and the supporting member 5.

[0051] As mentioned above, although this invention was demonstrated in detail, this invention is not limited to the said embodiment, Various changes can be added in the range which does not deviate from the summary of this invention.

[0052] In the operation panel of the present invention, the protruding portion 34 of the attenuator body 31 extending in the moving direction of the moving body 32 may be divided into a plurality of portions in the moving direction of the moving body 32. That is, the attenuator body 31 may include a plurality of protruding portions 34 arranged at intervals in the moving direction of the moving body 32.

[0053] In the operation panel of the present invention, the buffer member 6 is not limited to being formed in an elongated shape extending in the moving direction of the moving body 32, and may be divided into a plurality of parts in the moving direction of the moving body 32. That is, a plurality of buffer members 6 may be arranged at intervals in the moving direction of the moving body 32.

[0054] In the operation panel of the present invention, the supporting portion of the fader main body 31 that supports the display unit 4 is not limited to the protruding portion 34, and may be, for example, the facing surface 31a.

[0055] In the operation panel of the present invention, the support member 5 may be fixed to, for example, the mutually opposing side surfaces of two adjacent attenuator bodies 31. In this case, the support member 5 can also support the portion of the first display unit 4A supported by the two attenuator bodies 31 that is located between the two attenuator bodies 31. That is, the display unit 4A can be sandwiched between the attenuator bodies 31 and the base member 2 in a more stable state.

[0056] In the operation panel of the present invention, the base member 2 may constitute a housing for accommodating the attenuator device 3 and the display unit 4. In this case, the back surface 2b of the base member 2 constitutes the inner surface of the housing, and the front surface 2a of the base member 2 constitutes the outer surface of the housing.
