Description

  The present invention relates to a technique for enabling a desired position of an operation unit on a touch panel to be quickly and accurately identified in an electronic device including a touch panel.

  In an electronic device equipped with a touch sensor, in order to inform the user of the position of each operation unit, the touch sensor is made of a transparent material formed in a thin plate shape, and an electrostatic sensor disposed behind the touch sensor. Visible light emitted from a light source built in the capacitive switch is emitted to the front touch sensor.

  For example, the touch panel type liquid crystal display described in Patent Document 1 is formed by sequentially laminating a liquid crystal display plate, a switch plate, and a touch panel on a substrate, and a convex portion corresponding to the key position of the touch panel is provided on the surface of the touch panel. A transparent sheet is provided. Thereby, the key position of the touch panel, that is, the point to be touched can be clearly indicated by the convex portion of the transparent sheet. As a result, the operator can reliably touch the target key position with his / her fingertip without hesitation, targeting the convex portion on the key position. Furthermore, it is said that even visually impaired persons can recognize the key position of the touch panel by the convex portion of the transparent sheet.

Moreover, the touch panel described in Patent Document 2 is configured as follows. That is, the touch panel scans an optical signal from one side to the other side of the coordinate input surface, and sets the intersection as input coordinates. Further, the touch panel sets sub-coordinates by scanning optical signals in the vicinity of the input coordinates on the coordinate input surface. Further, the touch panel is provided with a recess on a desired side of the touch panel, a switch knob is disposed in the recess, and the switch knob and the recess are disposed on an extension line of the optical signal path. This helps to guide the operator's finger in both cases where the recess operates the switch knob and the touch panel surface, and ensures that the switch knob and the touch panel surface are searched for. It is supposed to be possible.

  However, in the touch panel type liquid crystal display described in Patent Document 1, the point to be touched is indicated by the convex portion of the transparent sheet as described above. When the touch panel type liquid crystal display as described above is mounted on an electronic device such as a karaoke apparatus in which operations are continuously performed, there is a problem that a visually impaired person cannot perform an operation appropriately.

  Further, in the touch panel type liquid crystal display described in Patent Document 1, the point to be touched is indicated by the convex portion of the transparent sheet. Therefore, when the touch panel is an electrostatic touch panel, the convex portion of the transparent sheet is The distance from the tip to the capacitance switch is larger than the distance from the surface of the touch panel to the capacitance switch, and there is a risk that the response sensitivity due to the capacitance switch when operating the convex portion will deteriorate, Even if the user is not visually impaired, the user may not be able to perform a quick input operation.

  In addition, in the touch panel described in Patent Document 2 described above, when the touch panel is an electrostatic touch panel, there are a concave portion that serves as a guide when operating and an input coordinate that is an operation position on the touch panel. Because it exists in different places, when operating the input coordinates, the position of the input coordinates on the touch panel in the horizontal direction can be specified, but it is difficult to specify the position of the input coordinates on the touch panel in the vertical direction. It was.

  Further, in the touch panel described in Patent Document 2 described above, when there are a large number of the input coordinates described above and a large number of input coordinates are arranged on the touch panel at a high density, an attempt is made to touch the desired input coordinates. In this case, since the human finger has a joint and bends to the upper left and right, for example, the finger may be inclined and it may be determined that the adjacent input coordinates are selected at the same time. For example, when a touch panel as described above is mounted on an electronic device such as a karaoke device in which a plurality of operations such as inputting and playing a song number are continuously performed in a karaoke room of a karaoke box, the ambient lighting is dark. In karaoke performed in a room, it is necessary for multiple users to quickly enter information such as song numbers in turn, so if there is an incorrect input as described above, Convenience may be impaired.

  This invention is made in view of such a malfunction, The place made into the objective is the technique which makes it possible to identify the position of the operation part on a desired touch panel rapidly and correctly in a karaoke apparatus provided with a touch panel. It is to provide.

  The operation panel of the karaoke apparatus according to claim 1, which has been made in order to solve the above problem, is provided with an opening made of a conductive material having conductivity (2a: in this section, in order to facilitate understanding of the invention, it is necessary. Accordingly, the reference numeral used in the column “Best Mode for Carrying Out the Invention” is attached, but it is not meant to limit the scope of the claims by this reference sign). The electronic component is mounted on the mounting surface of the substrate (120), and is made of a transparent material, is formed in a thin plate shape, covers at least a part of the opening of the casing, and the light source (130). The touch panel (140) having an operation unit (142) that is arranged to be positioned in front and is switched on and off by a touch operation by a user, and a material having transparency, A cover (150) that covers the front of the touch panel and covers at least a part of the opening of the housing, wherein the light source is a region centered on the operation portion of the touch panel. An identification part capable of tactilely or visually identifying the position of the operation part is formed on the outer surface of the cover, and the identification part is formed on the outer surface of the cover. The outer surface is formed as a part of a recess.

  According to the operation panel of the karaoke apparatus of the present invention configured as described above, the identification unit capable of tactilely or visually identifying the position of the operation unit is formed as a part of the recess on the outer surface of the cover. . By this, the user can identify the position of the operation unit by tactilely or visually confirming the position of the identification unit, and even visually impaired persons can confirm the position of the operation unit tactilely. Can do. In this case, even when the surrounding is dark, the user can tactilely check the position of the operation unit, and when the surrounding is bright, the user can visually check the position of the operation unit. it can.

  Moreover, since the identification part is formed as a part of the recess, the user can more easily confirm the position of the operation part. Also, when the identification part is formed as a part of the concave part, the user's finger is switched when the user's finger touches the identification part, rather than when the identification part is formed as a part of the convex part. Closer. As a result, the user can feel a sense closer to the operation of pressing the switch.

Therefore, it is possible to quickly and accurately identify the desired position of the operation unit on the touch panel.
In this case, it is conceivable that in the region including the position of the operation portion on the outer surface of the cover, a recess is continuously formed and the identification portion is formed as a part of the recess. According to this configuration, even if the position where the user's line of sight is dropped on the cover or the position where the user's finger touches the cover is away from the operation unit, the operation unit can be traced by following the recess visually or tactilely. Can arrive. Therefore, the user can more easily confirm the position of the operation unit.

  Further, it is conceivable that the above-mentioned recess is formed in an arc shape on the outer surface of the cover (claim 3). According to this configuration, even when the position where the user's line of sight is dropped on the cover or the position where the user's finger touches the cover is away from the operation unit, the concave portion formed in the arc shape is visually or tactilely. If you follow, you can reach the operation unit. Therefore, the user can more easily confirm the position of the operation unit.

  Further, it is conceivable that the above-mentioned recess is formed on the outer surface of the cover as a part of the circumference centered on the substantially central portion of the cover (claim 4). With this configuration, if the user is informed in advance of the type of the touch panel operation unit located on the left half side of the cover and the type of the touch panel operation unit located on the right half side of the cover, the shape of the recess It is possible to easily determine which type of operation unit is reached by following the concave portion by confirming whether or not the left side portion or the right side portion of the circumference.

  By the way, you may form so that a several identification part (252,253) may be included in the above-mentioned recessed part (251). Specifically, as in claim 5, it is conceivable that there are a plurality of identification portions and the recesses are formed to include a plurality of identification portions. With this configuration, if the user is informed in advance of the arrangement of the plurality of identification units on the recess, the user can easily determine which type of operation unit will be reached by following the recess. it can.

  In this case, it is considered that the plurality of identification portions are arranged on the recesses in a predetermined order (claim 6). Specific examples of the predetermined order include an operation order when reserving a karaoke performance song, an operation order for setting the volume and sound quality when entering the room, and an order often used by users. According to this configuration, the user can easily determine which type of operation unit is reached by following the recess without notifying the user of the arrangement of the identification unit in advance.

  Further, the plurality of identification portions described above are sequentially arranged clockwise or counterclockwise on a concave portion formed on the outer surface of the cover as a part of the circumference centered on the substantially central portion of the cover. (Claim 7). According to this configuration, the user can easily determine which type of operation unit is reached by following the recess without notifying the user of the arrangement of the identification unit in advance.

  Moreover, when a recessed part contains a some identification part as mentioned above, it is possible to comprise so that the depth of the part in which the identification part in a recessed part is located may each differ (Claim 8). As an example, the depth of the concave portion is configured in a step shape. For example, the volume operation unit “+” (plus) is set to a small depth, while the operation unit “−” (minus) is set to a large depth. With this configuration, for example, the user increases the volume when climbing a step while tracing with a finger, while the volume decreases when the step is lowered while tracing with a finger. Can be made uncomfortable during operation.

  In addition, about this invention, you may comprise as a karaoke apparatus provided with the housing | casing which has the opening part which consists of an electroconductive material which has electroconductivity, and the operation panel of the above-mentioned karaoke apparatus.

The electrostatic capacity switch 142 of the touch panel 140 can be reached by following the 151, the concave portion 152, and the concave portion 153 visually or tactilely. Therefore, the user can more easily confirm the position of the capacitance switch 142 of the touch panel 140.

  (4) Moreover, according to the communication karaoke apparatus 1 of 1st embodiment, the recessed parts 151,152,153 of the decorative panel 150 are the decorative panel 150 as a part of the circumference centering on the approximate center part of the decorative panel 150. It is formed on the outer surface. Accordingly, the type of the capacitance switch 142 of the touch panel 140 positioned on the left half side of the decorative panel 150 and the type of the capacitance switch 142 of the touch panel 140 positioned on the right half side of the decorative panel 150 are indicated to the user. If you let us know in advance, by checking whether the shape of the concave portion 151, the concave portion 152 and the concave portion 153 is the left side portion of the circumference or the right side portion of the circumference, It is possible to easily determine whether the capacitance switch 142 of the type touch panel 140 is reached.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

(1) Although the example which applied this invention to the communication karaoke apparatus 1 was given in the said embodiment, it is not restricted to this, It is also possible to apply this invention to electronic devices, such as an audio apparatus.
(2) In the above embodiment, the concave portion 151 is formed so as to include a single identification portion 154, and the same applies to the concave portion 152 and the concave portion 153. However, the present invention is not limited to this, and as illustrated in FIG. You may form so that the recessed part 251 of the decorative panel 250 may contain a some identification part. In the present embodiment, the concave portion 251 of the decorative panel 250 is formed to include two identification portions 252 and 253. In this way, if the user is informed in advance of the arrangement of the plurality of identification portions on the concave portion 251 of the decorative panel 250, the type of the touch panel 140 operation unit 142 can be reached by following the concave portion 251. The user can easily judge.

  (3) In this case, as illustrated in FIG. 7, the plurality of identification parts included in the recess 251 of the decorative panel 250 described above may be arranged on the recess 251 in a predetermined order. Specific examples of the predetermined order include an operation order when reserving a karaoke performance song, an operation order for setting the volume and sound quality when entering the room, and an order often used by users. In this way, any type of capacitance switch of the touch panel 140 can be traced through the recess 251 without informing the user of the arrangement of the plurality of identification units included in the recess 251 of the decorative panel 250 described above. The user can easily determine whether to reach 142.

  (4) In this case, it is conceivable that the above-described plurality of identification units 252 and 253 are sequentially arranged in a clockwise direction on the concave portion 251 drawn as a part of the circumference. For example, in the concave portion 251 formed in the left half region of the decorative panel 250, the identification unit 252 that is touched when the volume of the high sound is increased is above the identification unit 253 that is touched when the volume of the high sound is decreased. And so on. Further, in the recess 254 formed in the right half region of the decorative panel 250, the identification unit 255 that is touched when the volume of the bass is reduced is disposed above the identification unit 256 that is touched when the volume of the bass is increased. And so on. The plurality of identification units 252 and 253 described above may be sequentially arranged counterclockwise instead of sequentially arranged on the concave portion 251 drawn as a part of the circumference. In this way, any type of touch panel can be used as long as the user follows the recess 251 or the recess 254 without notifying the user of the arrangement of the plurality of identification units included in the recess 251 or the recess 254 of the decorative panel 250 described above. The user can easily determine whether to reach the 140 electrostatic capacitance switches 142.

  (5) Moreover, when the recessed part 251 of the decorative panel 250 contains several identification part as mentioned above, it is possible to comprise so that the depth of the part in which the identification part in the recessed part 251 is located may each differ. In this embodiment, the concave portion 251 of the decorative panel 250 is formed to include two identification portions 251 and 252. For example, as illustrated in FIG. 8A, the identification portion in the concave portion 251 is illustrated. The depth of the concave portion is configured to be stepped, for example, the depth of the portion 251a where the 252 is located is larger than the depth of the portion 251b where the identification portion 253 of the concave portion 251 is located. For example, the recess is formed by a plurality of steps. For example, for the identification unit 252 that is touched when the volume of a high tone is increased, the depth dimension is set large, while for the identification unit 253 that is touched when the volume of a high tone is decreased, the depth dimension is set small. And so on.

  At this time, if the depth of each part in the recessed part 251 is different, the distance between the capacitance switch 142 and the recessed part 251 is also different depending on the depth in each part of the recessed part 251 according to the depth of the recessed part 251 (FIG. 8 (b) distance L and distance M). If the distance at which the capacitance switch 142 is turned on is set to the distance L in advance in the control unit 143, the user's finger is placed on the portion 251b of the recess 251 where the identification unit 253 is located. The switch is turned on when touched, but the portion 251a of the recess 251 where the identification portion 252 is located is different in depth from the portion 251b where the identification portion 253 of the recess 251 is located is the distance before the finger touches the bottom surface At the time when it becomes L, there arises a problem that the capacitance switch 242 is turned on. Therefore, the distance for turning on the switch is set in advance in the control unit 143 as the distance M for the capacitance switch 242. That is, a new value generated by configuring the recess 251 with a plurality of steps by presetting in the control unit 143 a set value of the distance to be turned on according to the capacitance switches 142 and 242 having different depths of the recess 251. Can solve the problem.

  8B, since the distance between the capacitance switch 142 and the decorative panel 250 is constant, the communication karaoke apparatus 1 in which the plurality of recesses 251 are mounted is used. There is an effect that a complicated manufacturing process at the time of manufacturing is simplified as compared with the multi-stage recesses 251 shown in FIG.

  Further, instead of setting all the set values for turning on the capacitance switch 142 to the constant distance L, the distance between the bottom of the recess and the capacitance switch 142 is set to the distance L according to the depth of each part of the recess 251. As such, the position where the capacitance switch 142 is installed may be changed (see FIG. 8D).

  In this case, since the set value at which the capacitance switch 142 of the control unit 143 is turned on can be set to one type, the plurality of recesses 251 illustrated in FIG. 8D are illustrated in FIG. Compared to the plurality of recesses 251 shown, there is an effect that the memory capacity for storing the above set values can be reduced, or that the program to be controlled can be simplified.

  In this embodiment, as illustrated in FIG. 7, the display “+” (plus) is stamped at the position of the identification unit 252 on the decorative panel 250, and the display is displayed at the position of the identification unit 253 on the decorative panel 150. "-" (Minus) is stamped. Further, the display “+” (plus) is marked at the position of the identification portion 256 on the decorative panel 250, and the display “−” (minus) is marked at the position of the identification portion 255 on the decorative panel 150.

  In this way, for example, when the user steps up with a finger, the volume increases, while when the user steps down with a finger, the volume decreases. A feeling of incongruity during operation can be avoided.

  (6) In this case, it is conceivable to use a different capacitance switch for each identification unit. As an example, as illustrated in FIGS. 8B and 8C, the distance to the front object is smaller than the distance L behind the portion 251 a where the identification unit 252 is located in the recess 251. Whether or not the distance to the front object is smaller than the distance M (<L) behind the portion 251b where the identification portion 253 is located in the recess 251. For example, an electrostatic capacity switch 242 for determining whether or not is provided. In this case, it is conceivable that the distance from the back surface of the decorative panel 250 to the capacitance switch 142 and the distance from the back surface of the decorative panel 250 to the capacitance switch 242 are set to be approximately equal. Moreover, the control part 143 of the above-mentioned board | substrate 120 performs the following touch switch process (2) and touch switch process (3) instead of the above-mentioned touch switch process (1), and the control part 14 of the communication karaoke apparatus 1 Executes the next touch switch process (4). Below, it demonstrates in order.

[Description of touch switch processing (2)]
The touch switch process (2) executed by the control unit 143 of the substrate 120 based on the output signal from the capacitance switch 142 disposed behind the portion 251a where the identification unit 252 is located in the recess 251 below. The procedure will be described based on the flowchart of FIG. This touch switch process (2) is repeatedly executed independently from other processes when the communication karaoke apparatus 1 is activated.

  First, based on the output signal from the capacitance switch 142, it is determined whether or not the distance from the user's finger to the capacitance switch 142 is smaller than a predetermined distance L (S410). When it is determined that the distance from the user's finger to the capacitance switch 142 is smaller than the predetermined distance L (S410: Y), the user's finger is inside the recess 251 of the decorative panel 250 and is identified. When it is determined that the unit 252 is touched, the switch is turned on, and a signal indicating this is output to the CPU 14 (S420). Then, the process returns to S410.

  On the other hand, when it is determined that the distance from the user's finger to the capacitance switch 142 is greater than the predetermined distance L (S410: N), the user's finger is placed inside the recess 251 of the decorative panel 250. If the identification unit 252 is not touched, the switch is turned off, and a signal indicating that is output to the CPU 14 (S430). Then, the process returns to S410.

[Description of touch switch processing (3)]
The touch switch process (3) executed by the control unit 143 of the substrate 120 based on the output signal from the capacitance switch 242 disposed behind the portion 251b where the identification unit 253 is located in the recess 251 below. The procedure will be described based on the flowchart of FIG. This touch switch process (3) is repeatedly executed independently from other processes when the communication karaoke apparatus 1 is activated.

  First, based on the output signal from the capacitance switch 242, it is determined whether or not the distance from the user's finger to the capacitance switch 242 is smaller than a predetermined distance M (S510). When it is determined that the distance from the user's finger to the capacitance switch 242 is smaller than the predetermined distance M (S510: Y), the user's finger is inside the recess 251 of the decorative panel 250 and is identified. It is determined that the unit 253 is touched and the switch is turned on, and a signal indicating this is output to the CPU 14 (S520). Then, the process returns to S510.

  On the other hand, when it is determined that the distance from the user's finger to the capacitance switch 242 is larger than the predetermined distance M (S510: N), the user's finger is placed inside the recess 251 of the decorative panel 250. If the identification unit 253 is not touched, the switch is turned off, and a signal indicating this is output to the CPU 14 (S530). Then, the process returns to S510.

[Description of touch switch processing (4)]
Below, the process sequence of the touch switch process (4) performed by the control part 14 of the communication karaoke apparatus 1 is demonstrated based on the flowchart of FIG.9 (c). This touch switch process (4) is repeatedly executed independently from other processes when the communication karaoke apparatus 1 is activated.

  First, based on the output signal from the control unit 143 on the substrate 120, it is determined whether or not the capacitance switch 142 is on (S610). When it is determined that the capacitance switch 142 is on (S610: Y), the volume is reduced by controlling the MIDI sound source unit 18 and the audio processing unit 19 (S620). Then, the process returns to S610.

  On the other hand, if it is determined that the capacitance switch 142 is off (S610: N), whether or not the capacitance switch 242 is on is determined based on the output signal from the control unit 143 on the substrate 120. Judgment is made (S630). If it is determined that the capacitance switch 242 is on (S630: Y), the volume is increased by controlling the MIDI sound source unit 18 and the audio processing unit 19 (S640). Then, the process returns to S610. On the other hand, if it is determined that the capacitance switch 242 is off (S630: N), the process returns to S610 without doing anything.

  (7) It is also conceivable to use the same capacitance switch for a plurality of identification units. As an example, as illustrated in FIG. 8D, it is determined whether or not the distance to the front object is smaller than the distance L behind the portion 251 a where the identification unit 252 is located in the recess 251. An electrostatic capacity switch 142 is disposed, and an electrostatic capacity switch 142 that determines whether or not the distance to the object ahead is smaller than the distance L is also disposed behind the portion 251b where the identification unit 253 is located in the recess 251. And so on. In this case, the distance from the back surface of the decorative panel 250 to the capacitance switch 142 is set to be different between the capacitance switch 142 corresponding to the identification unit 252 and the capacitance switch 142 corresponding to the identification unit 253. Can be considered.
