  The present invention relates to an input device for executing a predetermined process and a vehicle device including the same.

  In recent years, the number of in-vehicle devices tends to increase, and the operation equipment in the passenger compartment has become complicated accordingly. As the number of operation switches increases, operability deteriorates and installation space for operation switches and the like is required. For this reason, the vehicle which operates a vehicle-mounted apparatus using a touch panel is increasing. For example, Patent Document 1 discloses a display device in which a touch panel for operating each operating state is superimposed on a display area that displays the operating state of an air conditioner. By this patent document 1, the installation space of the operating device of an air conditioner can be reduced.

  However, with the touch panel of Patent Document 1, it is difficult to give the user a feel at the time of operation, and it is difficult for the user to determine whether or not the user has surely pressed the button when pressing the displayed button. . Further, since the touch panel has a structure in which a plurality of glass or resin substrates are stacked, there is a problem that the structure becomes complicated and the cost increases.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an input device and a vehicle device that enable a reliable operation with a simple structure and a feeling of operation. It is in.

  An input device according to the present invention is an input device that detects a press on a flexible translucent plate provided on a display screen of a display device and outputs a predetermined signal. A light emitting means that emits light in a direction parallel to the plate-like surface, and a light receiving means that receives the light emitted from the light emitting means. .

For this reason, since the light emitted from the light emitting means is scattered by the bent portion, the amount of light received by the light receiving means is small in comparison with the case where the light transmitting plate is not pressed. Therefore, it is possible to detect the pressure on the light transmitting plate by detecting the magnitude of the amount of received light. Thus, a simple input device using a flexible translucent plate and a general optical detection means can be realized. In addition, since the translucent plate has flexibility, it is possible to give the user a feeling of pressing the translucent plate, so that the user can be surely grasped that the input operation has been performed. As a result, an operation error caused by performing the same input operation a plurality of times can be prevented.

  In the input device according to the present invention, the light-emitting means and the light-receiving means are configured such that an optical path through which light emitted from the light-emitting means to the light-receiving means passes is set inside the translucent plate. .

  In the present invention, since the optical path through which light passes is set inside the light transmissive plate, the light transmissive plate, the light emitting means, and the light receiving means can be arranged in substantially the same line. Thereby, an input device can control that the thickness of a display screen direction becomes large.

  In the input device according to the present invention, a gap is provided between the light transmitting plate and the display screen, and light emitted from the light emitting unit to the light receiving unit passes through the light emitting unit and the light receiving unit. The optical path is set in the gap.

  In the present invention, the light transmitting plate can be made thin by setting the optical path through which light passes outside the light transmitting plate. Thereby, the cost of a translucent board can be suppressed and it can suppress that the input device becomes thick in the display screen direction.

  In the input device according to the present invention, the light emitting unit includes a plurality of first light emitting units that emit light in one direction and a plurality of second light emitting units that emit light in a direction orthogonal to the one direction. The light receiving means includes a plurality of first light receiving means for receiving light emitted from the plurality of first light emitting means and a plurality of second light receiving means for receiving light emitted from the plurality of second light emitting means, respectively. It is characterized by having.

  In this invention, the press position to a translucent board is detectable by emitting light in a grid | lattice form along a translucent board. Accordingly, it is possible to assign a process to be executed according to the pressed position, and it is possible to suppress an increase in the number of operation switches and the like even if the number of devices operated by the input device increases.

  The input device according to the present invention is characterized in that the light receiving means is a one-dimensional image sensor.

  In the present invention, since the intensity of light can be detected by using a general one-dimensional image sensor, it is possible to more reliably detect the pressure on the light transmitting plate.

  In the input device according to the present invention, the light emitting means includes a light emitting element and an optical fiber that guides light emitted from the light emitting element, and emits light guided by the optical fiber. It is characterized by being.

  In the present invention, by using an optical fiber, the light emitting element can be provided at a position away from the display device, so that the degree of design freedom can be improved.

  In the present invention, since an optical fiber is used, the light receiving element can be provided at a position away from the display device, so that the degree of design freedom can be improved.

  The input device according to the present invention is mounted on a vehicle, and further includes control means for controlling the operation of a device mounted on the vehicle based on light reception by the light receiving means.

  In this invention, since the apparatus mounted in the vehicle can be operated reliably, the accident accompanying apparatus operation can be prevented.

And stop means for stopping control of the operation of the device.

  In the present invention, it is possible to switch between using and not using the input device by switching the display contents of the display means as necessary.

  The present invention passes the display screen side from the translucent plate and emits light parallel to the plate-like surface, so that the translucent plate is bent when the flexible translucent plate is pressed to the display screen side. The shaded part and the light come to intersect. For this reason, since the light emitted from the light emitting means is scattered by the bent portion, the amount of light received by the light receiving means is small in comparison with the case where the light transmitting plate is not pressed. Therefore, it is possible to detect the pressure on the light transmitting plate by detecting the magnitude of the amount of received light. Thus, a simple input device using a flexible translucent plate and a general optical detection means can be realized. In addition, since the translucent plate has flexibility, it is possible to give the user a feeling of pressing the translucent plate, so that the user can be surely grasped that the input operation has been performed.

(Embodiment 1)
Hereinafter, an input device according to a first embodiment of the present invention and a vehicle device including the input device will be described with reference to the drawings.

  FIG. 1 is a schematic view of a vehicle device provided with an input device according to the present invention. The vehicle device according to the present embodiment is connected to an air conditioner (not shown) that adjusts the air conditioning in the vehicle, and the air conditioner can be operated from the vehicle device.

  The vehicle device includes a liquid crystal display 1 installed near the center of the vehicle instrument panel, and a transparent resin sheet 2 polymerized on the front surface of the liquid crystal display 1. As shown in FIG. 1A, the liquid crystal display 1 displays an operation screen of the air conditioner. The operation screen includes information related to air conditioning such as temperature and wind direction, and a plurality of button images 11. Since the resin sheet 2 is transparent, the user can visually recognize the operation screen displayed on the liquid crystal display 1 through the resin sheet 2. As will be described in detail later, processing corresponding to the button image 11, for example, adjustment of temperature or air volume, is performed by pressing the portion of the resin sheet 2 that overlaps the button image 11.

  Near the liquid crystal display 1 (downward in the figure), push switches 51 and 52 for operating the air conditioner, a dial switch 53, and the like are provided. The user can also adjust the temperature or air volume of the air conditioner by using these switches 51, 52 and 53.

  An image other than the operation screen of the air conditioner is also displayed on the liquid crystal display 1. In the present embodiment, the air conditioner is connected to an in-vehicle camera (not shown). As shown in FIG. 1B, the liquid crystal display 1 has a vehicle peripheral image captured by the in-vehicle camera (for example, the rear of the vehicle). Image) is displayed. Switching between the display of the operation screen and the peripheral image may be performed manually or automatically. When switching automatically, for example, the vehicle device acquires the position of the gear range, displays the operation screen when the gear is not in the R range, and switches from the operation screen to the surrounding image when the gear is in the R range. Can do.

  Fig.2 (a) is a front view which shows typically a part of vehicle apparatus, (b) is sectional drawing in the II line. The vehicle equipment includes a liquid crystal display 1, a resin sheet 2, a light emitting unit 3, a light receiving unit 4, and the like.

  The liquid crystal display 1 displays an operation screen for operating the air conditioner as described above. The liquid crystal display 1 includes a rectangular liquid crystal panel 1a and a backlight 1b disposed on the back side of the liquid crystal panel 1a. The liquid crystal panel 1a displays an image by blocking or transmitting light emitted by a light source such as the backlight 1b.

  The resin sheet 2 has substantially the same shape as the liquid crystal panel 1a and is provided in front of the liquid crystal panel 1a. The resin sheet 2 has flexibility, and when pressed from the outside, the pressed portion is recessed (flexed) toward the liquid crystal panel 1a and returns to its original state when the pressing force disappears. Yes. Thus, since the resin sheet 2 has flexibility, when the user presses the resin sheet 2 and operates the air conditioner, a pressing feeling can be given to the user.

  The light emitting unit 3 is an infrared light emitting diode that emits light parallel to the surface of the resin sheet 2 from one side surface of the resin sheet 2 toward the opposite side surface. Four light emitting units 3 are arranged at equal intervals along one long side of the resin sheet 2, and three light emitting units 3 are arranged at equal intervals along one short side.

  The light receiving unit 4 is an infrared light receiving element that receives light emitted from the light emitting unit 3. The light receiving unit 4 is provided to face the light emitting unit 3. Specifically, four light receiving parts 4 are arranged along the other long side facing one long side of the resin sheet 2 on which the light emitting part 3 is arranged. Moreover, the three light-receiving parts 4 are arrange | positioned along the other short side facing one short side of the resin sheet 2 in which the light emission part 3 is arrange | positioned.

  The light emitting unit 3 and the light receiving unit 4 are installed with respect to the resin sheet 2 so that an optical path through which light passes is set inside the resin sheet 2. Moreover, the resin sheet 2 is generated so that at least a pressed portion can intersect the optical path. Thus, the light emitting unit 3 and the light receiving unit 4 function as a detecting unit that detects that the resin sheet 2 is pressed. In addition, the relationship between the pressing force to the resin sheet 2 and the amount of bending with respect to the pressing force is not particularly limited and can be changed as appropriate.

  Hereinafter, a method for detecting the pressure on the resin sheet 2 will be described.

  3A and 3B are diagrams for explaining a method of detecting the pressure on the resin sheet 2, in which FIG. 3A shows the state of light when the resin sheet 2 is not pressed, and FIG. ing.

  As shown in FIG. 3A, when the resin sheet 2 is not pressed, the light receiving unit 4 can receive the light emitted from the light emitting unit 3 as it is. On the other hand, when the resin sheet 2 is pressed, as shown in FIG. 3B, the pressed portion is recessed and intersects the optical path, so that the light emitted from the light emitting unit 3 is recessed in the resin sheet 2. Scattered by part. As a result, the amount of light received by the light receiving unit 4 is reduced in comparison with the case where the resin sheet 2 is not pressed. Accordingly, when the amount of received light detected by the light receiving unit 4 is equal to or greater than the threshold value, the pressure is detected, and when the amount is less than the threshold value, the pressure is not detected. The threshold value is determined by the transmittance of the resin sheet 2 and the like.

  Next, a method for detecting the position of the pressed resin sheet 2 will be described.

  4A and 4B are diagrams for explaining a method for detecting the pressed position of the resin sheet 2, wherein FIG. 4A is a diagram showing an optical path arranged on the resin sheet 2, and FIG. FIG.

  As shown in the figure, the light receiving parts 4 arranged along the long sides of the resin sheet 2 are designated as X1, X2, X3, X4, and the light receiving parts 4 arranged along the short sides are designated as Y1, Y2, Y3. And When the amount of received light detected by the light receiving unit 4 is equal to or greater than the threshold, the amount of received light is “Hi”, and when it is less than the threshold, the amount of received light is “Lo”. At this time, for example, when a portion where light paths through which light received by the light receiving unit X2 and the light receiving unit Y3 passes is crossed (a hatched portion in the figure), the received light amount detected by the light receiving unit X2 and the light receiving unit Y3 is “Lo”. Thus, the amount of received light detected by the other light receiving units is “Hi”. Thereby, it can detect that the said part was pressed.

  Note that the above-described button image 11 of FIG. 1 is displayed so as to overlap at a portion where two optical paths intersect. Thereby, by detecting the pressing of the resin sheet 2, it can be determined that the button image 11 that overlaps the pressed position is pressed.

  FIG. 5 is a block diagram schematically showing the electrical configuration of the vehicle device. The vehicle device 20 includes a liquid crystal display 1, a light emitting unit 3, a light receiving unit 4, an operation unit 5, a display control unit 6, a light emission control unit 7, an operation input unit 8, a communication unit 9, a control unit 10, and the like.

  The operation unit 5 is the switches 51, 52, and 53 described with reference to FIG. The display control unit 6 performs display control of the liquid crystal display 1. The light emission control unit 7 performs light emission control of the light emitting unit 3. The operation input unit 8 receives the light received by the light receiving unit 4 and the signal input from the operation unit 5.

  The communication unit 9 enables data communication with the air conditioner 21, the in-vehicle camera 22, another ECU (Electronic Control Unit) 23, and the like via an in-vehicle LAN (Local Area Network). The vehicle device 20 acquires information such as the air volume, temperature, and wind direction from the air conditioner 21. The in-vehicle camera 22 is installed, for example, at the rear of the vehicle, and the vehicle device 20 acquires an image of the rear of the vehicle captured by the in-vehicle camera 22. The ECU 23 is a body system ECU disposed everywhere in the vehicle, and the vehicle device 20 acquires vehicle information such as a gear range from the ECU 23.

  The control unit 10 is, for example, a CPU (Central Processing Unit) or an ECU. The control unit 10 inputs and outputs data with the air conditioner 21 and the like, and performs overall operation control of the vehicle device 20 based on the data acquired from the air conditioner 21 and the signal received by the operation input unit 8.

  Next, the operation of the vehicle device 20 configured as described above will be described.

  FIG. 6 is a flowchart showing processing performed by the vehicle device 20. The control unit 10 starts operation when, for example, an ignition switch is turned on, and first performs initialization (S1). In initialization, processing such as erasing data stored in a RAM (Random Access Memory) or the like and displaying an initial screen on the liquid crystal display 1 is performed. Next, the control unit 10 determines whether or not the position of the gear range acquired from the ECU 23 is the R range (S2). When it is R range (S2: YES), the control part 10 performs the process after S11. When not in the R range (S2: NO), the control unit 10 displays the operation screen of the air conditioner 21 as shown in FIG. 1A (S3). And the control part 10 starts the light emission from the light emission part 3 (S4).

  The control unit 10 determines whether or not the amount of received light detected by the light receiving unit 4 has changed (S5). When the amount of received light has not changed (S5: NO), the control unit 10 determines that there is no pressure on the resin sheet 2, and executes the processes after S8. When the amount of received light changes (S5: YES), the control unit 10 detects the pressed position (S6). Specifically, when the resin sheet 2 is pressed, the light emitted from the light emitting unit 3 is scattered by the pressed part, so that the amount of received light detected by the light receiving unit 4 is small. Then, as described with reference to FIG. 4, the control unit 10 detects the two light receiving units 4 in which the amount of received light is small, and determines the intersection of the optical paths corresponding to the detected light receiving unit 4 as the pressed position.

  Next, the control part 10 performs the process corresponding to the detected pressing position (S7), and determines whether a process is complete | finished (S8). The condition for ending the process is, for example, when the ignition switch is turned off. When the process ends (S8: YES), the control unit 10 ends the process. When the process is not terminated (S8: NO), the control unit 10 determines again whether or not the position of the gear range is the R range (S9). When it is not the R range (S9: NO), the control unit 10 executes the processes after S5. When it is R range (S9: YES), the control part 10 stops light emission of the light emission part 3 (S10). Thereby, the resin sheet 2 can be pressed and reception of the operation of the air conditioner 21 can be stopped. In addition, when displaying the camera image, the control unit 10 does not stop the light emission of the light emitting unit 3 and detects the pressing of the resin sheet 2 so as to invalidate the process, thereby operating the air conditioner 21. May not be accepted. Then, the control part 10 performs the process after S11.

  In S <b> 11, the control unit 10 displays the camera image acquired from the in-vehicle camera 22 on the liquid crystal display 1. Next, it is determined whether or not to end the process (S12). When the process ends (S12: YES), the control unit 10 ends the process. When the process is not terminated (S12: NO), the control unit 10 determines again whether or not the position of the gear range is the R range (S13). When it is not the R range (S13: NO), the control unit 10 executes the processes after S3. When it is R range (S13: YES), the control part 10 performs the process after S11.

  As described above, in this embodiment, an optical path through which light passes is set inside the resin sheet 2, and when the resin sheet 2 is pressed, the bent portion of the resin sheet 2 and the optical path intersect. To come. For this reason, since the light emitted from the light emitting unit 3 is scattered by the bent portion, the amount of received light detected by the light receiving unit 4 is small in comparison with the case where the resin sheet 2 is not pressed. Therefore, the pressure on the resin sheet 2 can be detected by detecting the magnitude of the amount of received light. Thus, a simple input device using the resin sheet 2 and the general optical light emitting unit 3 and light receiving unit 4 can be realized and can be mounted on the vehicle device 20. In addition, since the resin sheet 2 has flexibility, it is possible to give the user a feeling of pressing the resin sheet 2, so that the user can be surely grasped that the input operation of the vehicle device 20 has been performed. As a result, it is possible to prevent an operation error caused by performing the same input operation a plurality of times and to prevent an accident caused by an input operation during driving.

(Embodiment 2)
Next, an input device according to a second embodiment of the present invention and a vehicle device including the input device will be described with reference to the drawings. In the first embodiment, an optical path through which light for detecting pressure is passed is set inside the resin sheet 2, but in the second embodiment, it is set outside the resin sheet 2. In the second embodiment, a light emitting element that emits light and a light receiving element that receives light are provided at positions away from the resin sheet 2. Hereinafter, only different points will be described, the same reference numerals are given to the same members as those in the first embodiment, and the description will be omitted.

  FIG. 7 is a diagram schematically illustrating a part of the vehicle device according to the present embodiment.

  The vehicle device according to the present embodiment includes a liquid crystal display 1 and a resin sheet 2 as in the first embodiment. Further, the vehicle device includes a light emitting unit 12 and a light receiving unit 13 provided on the detection substrate 14 at a position away from the liquid crystal display 1 or the like. The light emitting unit 12 is an infrared light emitting diode. The light receiving unit 13 is a one-dimensional image sensor. A connector 12a is connected to the light emitting unit 12, and a plurality of optical fibers 15 are further connected to the connector 12a. The light guided by the optical fiber 15 is irradiated between the liquid crystal display 1 and the resin sheet 2 in parallel with the resin sheet 2. Similarly, a plurality of optical fibers 16 are connected to the light receiving unit 13 via a connector 13a. The optical fiber 16 receives light from the optical fiber 15 and guides the light to the light receiving unit 13.

  With this configuration, the light emitted from the light emitting unit 12 is guided by the optical fiber 15 through the optical fiber 16 and emitted to detect the pressing of the resin sheet 2. The light receiving unit 13 receives light guided by the optical fiber 16 and detects the amount of received light. By using the optical fibers 15 and 16, the light emitting unit 12 and the light receiving unit 13 can be provided at positions away from the irradiation position. For this reason, the restriction | limiting etc. at the time of installing an element on a circuit can be eased. Moreover, since the light of the light emission part 12 is branched by the some optical fiber 15, since a some light emission source is not required, cost reduction is attained.

  FIG. 8 is a diagram for explaining a method of detecting the pressure on the resin sheet. FIG. 8A shows a state of light when the resin sheet 2 is not pressed, and FIG. Yes. As shown in FIG. 8, the resin sheet 2 is disposed opposite to the liquid crystal display 1 with a space provided between the resin sheet 2 and the liquid crystal display 1. The light emitting unit 12 and the light receiving unit 13, specifically, the optical fibers 15 and 16 connected to each of the light emitting unit 12 and the light receiving unit 13 are provided so as to set an optical path in a space provided between the liquid crystal display 1 and the resin sheet 2. .

  As shown in FIG. 8A, when the resin sheet 2 is not pressed, the light receiving unit 13 can receive the light emitted from the light emitting unit 12 as it is. On the other hand, when the resin sheet 2 is pressed, as shown in FIG. 8B, the pressed portion is recessed and intersects the optical path, so that the light emitted from the light emitting unit 12 is recessed in the resin sheet 2. Scattered by part. As a result, the amount of light received by the light receiving unit 13 is small in comparison with the case where the resin sheet 2 is not pressed. Therefore, when the amount of received light detected by the light receiving unit 13 is equal to or greater than the threshold value, the pressure is detected, and when the amount is less than the threshold value, the pressure is not detected. Thus, the resin sheet 2 can be made thin by setting the optical path through which light passes outside the resin sheet 2. Thereby, the cost of the resin sheet 2 can be suppressed.

  As described above, the second embodiment has an effect that the cost can be reduced by reducing the thickness of the resin sheet 2 in addition to the same effect as the first embodiment. Moreover, by using the optical fibers 15 and 16, the number of the light emission parts 12 and the light-receiving parts 13 can be reduced, the simplification of an apparatus and the freedom degree of component arrangement | positioning can be improved.

  In the above-described embodiment, the vehicle device 20 has been described as operating an air conditioning device. However, the vehicle device 20 may operate other in-vehicle devices such as a car navigation system and an audio device, and may include a plurality of in-vehicle devices. May be operated. Moreover, the number of light-receiving parts and light-emitting parts can be suitably changed according to the range (accuracy) of the pressed position of the resin sheet 2 to detect.

  Moreover, although the light emission part 3 and the light-receiving part 4 are arrange | positioned on both sides of the resin sheet 2 in Embodiment 1, you may arrange | position each on the same side. FIG. 9 is a diagram for explaining another method for detecting the pressure on the resin sheet. As shown in FIG. 9, the light receiving portion 4 is emitted from the light emitting portion 3 and receives the light scattered by the recessed portion when the resin sheet 2 is pressed. In this case, the light receiving unit 4 detects the pressing by receiving the scattered light instead of the received light amount. In this case, the degree of freedom of element arrangement may be improved.

  The preferred embodiments of the present invention have been specifically described above, but each configuration, operation, and the like can be appropriately changed and are not limited to the above-described embodiments.
