Is displayed.
JP 7-2111182 (page 3-4, FIG. 1)

  By the way, from the viewpoint of universal design, display items such as characters and pictures displayed on the switch have a desired size depending on the operator. Since the technology of Patent Document 1 is a structure using a display, it is possible to change the display size of characters and patterns displayed on the pressing surface of the switch by changing the size of the image projected on the switch. The document does not disclose anything about that. Further, when a display is used, the display is an expensive part, and therefore, a structure that does not use a display has been desired in order to reduce the cost of parts required for this type of apparatus.

  An object of the present invention is to provide a display size variable display device that can freely change the display size of a display object displayed on the surface of a case without using expensive parts.

In order to solve the above problems, in the present invention, a space in the case is partitioned into a plurality of compartments, and a plurality of light paths each having a design property are formed by combining a light-transmitting portion with a light-shielding portion. A partition member, a plurality of light sources that are provided for each of the plurality of partition chambers and irradiate the interior of each of the partition chambers, and light from the surface side of light that transmits light from the light source side can be reflected. And a semi-transmissive member provided to form a pair with the partition member, a projection member that projects light passing through the optical path as an image when the light source is turned on, and an operating state of the operating means. And the control means for controlling the lighting of the light source, the optical path having a design property is formed in the partition member so that the size of the optical path increases in order from the lower side, and the operation state of the operation means is set. Depending on the light source By lighting the one selectively, and summarized in that for switching the size of the image projected on the projection member.

  According to this configuration, if the light source at the lowest position among the plurality of light sources arranged in the vertical direction is turned on, the light is irradiated into the compartment at the lowest position where the light source is located. Then, this light first passes through the optical path of the partition member positioned at the lowest position, and then sequentially passes through the optical path of the partition member positioned at the top, and the shape of the optical path of the partition member positioned at the lowest position is an image. It is in the state projected on the projection member. At this time, since the optical path of the partition member positioned at the lowest position is formed in a small size, when light first passes through the optical path, a small-size image is reflected on the projection member. .

  On the other hand, if the uppermost light source is turned on among a plurality of light sources arranged in the vertical direction, light is irradiated into the uppermost compartment where the light source is located. Then, this light reaches the projection member through the optical path of the partition member positioned at the uppermost position, and the shape of the optical path of the partition member positioned at the uppermost position is projected onto the projection member as an image. At this time, since the optical path of the partition member located at the uppermost position is formed in a large size, when light first passes through the optical path, a large-size image is reflected on the projection member.

  Therefore, in the present invention, it is possible to switch the size of the image projected on the projection member by selectively switching the light source to be lit, so that the projection member is mounted on the outer frame case of the display size variable display device. If it is a part, it becomes possible to freely change the display size of display objects such as characters and designs displayed on the case surface. In addition, even if the display size of the display object reflected on the case surface can be changed in this way, it can be implemented using an inexpensive member that is easily available, so there is a concern that the cost of parts will increase when this is performed. Nor.

  According to this configuration, the light emitted from the light source is reflected upward by the semi-transmissive member located one lower side of the light, so that most of the light goes to the projection member. Accordingly, since the amount of light reaching the projection member increases, an image reflected on the projection member tends to be clearly projected.

The gist of the present invention is that the partition member and the semi-transmissive member forming a set are integrally formed.
According to this configuration, it is not necessary to perform the part assembling process of the partition member and the semi-transmissive member in separate processes, and the number of assembling processes when assembling these members to the case of the display size variable display device is reduced. Is possible.

  In the present invention, the partition chamber is partitioned into a plurality of sections in the plane direction, the light sources are provided for each of the partitioned compartments, and the partition member forming a set with the partition chamber has the optical path for each of the partitioned partitions. Are provided in different sizes.

  According to this configuration, since a plurality of light transmitting portions are provided in the same compartment, it is possible to project images of different sizes on the projection unit even in the same compartment. Therefore, the number of types of images that can be projected onto the projection member increases, leading to an improvement in user satisfaction of the display size variable display device.

  In the present invention, the operating means includes first operating means that is operated when changing the display size of the image projected on the projection member, and second operating means that is operated when operating various devices. The control means switches on / off of lighting of the light source based on the operation of the second operation means, and is set by the first operation means when projecting the image on the projection member. The gist is to turn on the corresponding light source so that the image of the display size is projected onto the projection member.

  According to this configuration, for example, it is possible to perform an operation of turning off the light source and displaying an image on the projection unit when the second operation unit is operated, with the light source turned off in the normal state. Become.

  According to the present invention, the display size of the display object displayed on the case surface can be freely changed without using expensive parts.

Hereinafter, an embodiment of a variable display size display device embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, in the vicinity of the steering wheel 2 provided in the driver's seat of the vehicle 1, a momentary lever 3 that is operated when operating the direction indicator of the vehicle 1 is provided. When the momentary lever 3 is tilted upward from the center position with the base end as a fulcrum, for example, the left direction indicator blinks, and when it is tilted downward from the center position, for example, the right direction indicator The instrument blinks. The momentary lever 3 is also used when performing a dimmer / passing operation on the headlight of the vehicle 1 by performing a tilting operation in the front-rear direction from the neutral position. The momentary lever 3 constitutes an operating means (first operating means).

  As shown in FIGS. 2 and 3, a display unit 5 is incorporated in the case 4 of the momentary lever 3 to display a display object such as characters and designs on the surface of the case 4 while changing the display size. ing. When the momentary lever 3 is operated, the display unit 5 of this example displays the left and right direction indicators blinking by changing the display size between the left arrow Ya and the right arrow Yb. The display unit 5 corresponds to a display size variable display device.

  The display unit 5 is provided with a box-shaped frame 6 having an open upper wall. The inside of the frame body 6 is divided into two chambers by a dividing wall 7 (see FIG. 3) standing upright in the center. One space is a first housing portion 8 and the other space is a second housing portion 9. Yes. The first housing portion 8 houses a left-pointing arrow display unit component 10 that displays a left-pointing arrow Ya, and the second housing portion 9 houses a right-pointing arrow display unit component 11.

  Hereinafter, the details of the unit parts 10 and 11 will be described. However, since they are different only in the design of the arrows and other configurations are the same, only the left-pointing arrow display unit part 10 will be described. Inside the first accommodating portion 8, a plurality (three in this example) of mask film plates 12 to 14 that divide the space in the first accommodating portion 8 are arranged in parallel in the vertical direction. . The mask film plates 12 to 14 in this example are formed in a thin plate shape and are arranged at equal intervals in the vertical direction (parallel direction). In this example, it is set as the 1st mask film board 12, the 2nd mask film board 13, and the 3rd mask film board 14 in order from the lower side among these three mask film boards 12-14. The mask film plates 12 to 14 correspond to partition members.

  In the inside of the 1st accommodating part 8, the internal space is divided by these mask film plates 12-14, and the 1st division room 15, the 2nd division room 16, and the 3rd division room 17 are sequentially formed from the lower side. It is formed with the same volume. That is, the space surrounded by the first mask film plate 12 and the inner surface of the frame body 6 becomes the first compartment 15, and is surrounded by the first mask film plate 12, the second mask film plate 13, and the inner surface of the frame body 6. The space is the second compartment 16, and the space surrounded by the second mask film plate 13, the third mask film plate 14, and the inner surface of the frame 6 is the third compartment 17.

  Each of the mask film plates 12 to 14 has a multilayer structure in which a plurality of different types of layers are overlapped. This will be described with reference to the first mask film plate 12. A light transmitting portion 12 a made of a transparent resin material is provided in the lowermost layer of the first mask film plate 12. On the upper surface of the translucent part 12a, a black resin film is masked as a light-shielding part 12b except for the shape of the display object projected on the momentary lever 3. Therefore, the unmasked portion becomes an optical path 12x having a design property, and the light passing through the optical path 12x is projected on the momentary lever 3 as a display object. In this example, the upper surface of the translucent part 12a is masked with a black resin material except for the arrow-shaped part.

  As shown in FIG. 3, the optical paths 12x to 14x respectively formed on the mask film plates 12 to 14 have the same design between the mask film plates 12 to 14, but the size increases from the bottom toward the upper film plate. Is formed in a shape that gradually increases. Further, these optical paths 12x to 14x are located in the optical path 14x of the third mask film plate 14 and the optical paths 12x of the first mask film plate 12 and the second mask film plate 13 when the display unit 5 is viewed from above. It is arranged at a position where all 13x enters.

  As shown in FIGS. 2 and 3, half mirrors 12 c to 14 c that transmit only light from one surface are provided on the upper surfaces of the light shielding portions 12 b to 14 b masked on the upper surfaces of the respective light transmitting portions 12 a to 14 a. Are provided. These half mirrors 12c to 14c are in an attached state in which the light transmitting side faces the light shielding part side and the light reflecting side faces the anti-light shielding part side. The half mirror 12c is integrally formed with respect to the plate material composed of the light transmitting portion 12a and the light shielding portion 12b, and the half mirrors 13c and 14c have the same structure. The half mirrors 12c to 14c correspond to semi-transmissive members.

  As shown in FIG. 2, a printed circuit board 18 on which electrical parts of the display unit 5 are mounted is attached to the inner side surface of the frame body 6 so as to stand vertically with respect to the bottom surface of the frame body 6. . A plurality (three in this example) of LEDs 19 to 21 are mounted on the printed circuit board 18 according to each of the first compartment 15 to the third compartment 17. That is, the printed circuit board 18 is provided with a first LED 19 as a light source for the first compartment 15, a second LED 20 is provided as a light source for the second compartment 16, and a third LED 21 is provided as a light source for the third compartment 17. Is provided. The first compartment 15 to the third compartment 17 are formed in a sealed space so that light does not leak outside when the corresponding LED in each chamber is lit. Although not shown, a plurality of LEDs for the right-pointing display unit component 11 are also mounted on the printed circuit board 18 for each compartment. The LEDs 19 to 21 correspond to light sources.

  A thin projection plate 22 made of, for example, a translucent material is attached to the opening 6 a of the frame 6. When any one of the first LED 19 to the third LED 21 is lit (or blinks), the projection plate 22 is used to display the display bodies of the optical paths 12x to 14x formed in the mask film plates 12 to 14 that form a pair with the lit LED. The image is displayed face up as an image with the shape size. That is, if the first LED 19 is turned on, a small right arrow Ya formed on the first mask film plate 12 by the optical path 12x is projected onto the projection plate 22, and if the third LED 21 is turned on, the third mask film is formed by the optical path 14x. A large right arrow Ya formed on the plate 14 is projected onto the projection plate 22. Since the projection plate 22 becomes the display area E (see FIG. 1) indicated by the arrows Ya and Yb, this constitutes a part of the case 4 of the momentary lever 3. The projection plate 22 corresponds to a projection member.

  A display control ECU (Electronic Control Unit) 23 that controls lighting states of the first LED 19 to the third LED 21 is connected to the printed circuit board 18. The display control ECU 23 is connected to the momentary lever 3 via a lever switch circuit 24 that detects the operation position of the momentary lever 3. The lever switch circuit 24 outputs a switch signal corresponding to the operation position of the momentary lever 3 to the display control ECU 23. Based on the switch signal input from the lever switch circuit 24, the display control ECU 23 switches the first LED 19 to the third LED 21 on and off so that the LED starts to light when the lever is operated.

  A switching knob 25 that is operated when switching the size of the image projected on the momentary lever 3 is provided near the steering wheel 2 in the driver's seat. As the switching knob 25, for example, a rotary type that switches the selection position by a twisting operation is used. In this example, the display size can be switched in three stages, so that the large size display position, the medium size display position, and the small size are displayed. The position can be switched between three display positions.

  A switching knob 25 is connected to the display control ECU 23 via a knob switch circuit 26 that detects an operation position of the switching knob 25. The knob switch circuit 26 outputs a switch signal corresponding to the operation position of the switching knob 25 to the display control ECU 23. The display control ECU 23 selectively selects the first LED 19 to the third LED 21 based on the switch signal input from the knob switch circuit 26 so that the LED corresponding to the operation position of the switching knob 25 is lit among the first LED 19 to the third LED 21. Turn on. The display control ECU 23 corresponds to control means, and the switching knob 25 constitutes operation means (second operation means).

Next, the operation of the display size variable display device of this example will be described.
First, it is assumed that the momentary lever 3 is tilted upward, for example, from the neutral position in a state where the switching knob 25 is operated to the small size display position. At this time, the display control ECU 23 detects from the lever switch circuit 24 that the momentary lever 3 is tilted upward. At this time, the switch knob 25 is moved from the knob switch circuit 26 to the small size display position. A switch signal indicating that it is located at is input. Therefore, the display control ECU 23 recognizes that the small-size left-pointing arrow Ya should be displayed on the momentary lever 3, and turns on (or blinks) the first LED 19.

  When the first LED 19 is turned on, the first compartment 15 is illuminated by the first LED 19. At this time, the light from the first LED 19 passes through the optical path 12x of the first mask film plate 12, and subsequently passes through the optical path 13x of the second mask film plate 13 and the optical path 14x of the third mask film plate 14 to the projection plate 22. To the back. In addition, since the size of the optical path 13x of the second mask film plate 13 and the optical path 14x of the third mask film plate 14 is formed larger than the size of the optical path 12x of the first mask film plate 12, the first mask film It is difficult for the light passing through the optical path 12x of the plate 12 to be blocked by the second mask film plate 13 and the third mask film plate 14.

  Thus, the projection plate 22 projects the shape of the optical path 12x of the first mask film plate 12, that is, the image of the small left arrow Ya, and the left arrow Ya is displayed on the momentary lever 3. It becomes. Therefore, the driver can recognize that the left direction indicator is blinking by looking at the small left arrow Ya reflected in the momentary lever 3.

  By the way, when the left arrow Ya displayed on the momentary lever 3 has a small size, there are cases where it is desired to increase the size of this image because it is too small to be seen easily. At this time, by rotating the switching knob 25, the operation position is switched from the small size display position to the medium size display position.

  It is assumed that the momentary lever 3 is tilted upward from the neutral position in a state where the switching knob 25 is operated to the medium size display position. At this time, the display control ECU 23 detects from the lever switch circuit 24 that the momentary lever 3 has been operated upward. At this time, from the knob switch circuit 26, the switching knob 25 is positioned at the medium size display position. Input a switch signal to the effect. Therefore, the display control ECU 23 recognizes that the medium-sized left-pointing arrow Ya should be displayed on the momentary lever 3, and turns on (or blinks) the second LED 20.

  When the second LED 20 is turned on, the second compartment 16 is illuminated by the second LED 20. At this time, the light of the second LED 20 is reflected by the half mirror 12c of the first mask film plate 12, so that most of the light is directed upward. Then, the light of the second LED 20 passes through the optical path 13x of the second mask film plate 13, and this light reaches the back surface of the projection plate 22 via the optical path 14x of the third mask film plate 14. In addition, since the size of the optical path 14x of the third mask film plate 14 is formed larger than the size of the optical path 13x of the second mask film plate 13, the light passing through the optical path 13x of the second mask film plate 13 is It is difficult to fall into a situation where it is blocked by the third mask film plate 14.

  As described above, the shape of the optical path 13x of the second mask film plate 13, that is, the image of the medium-sized left arrow Ya is projected onto the projection plate 22, and this medium size reflected on the momentary lever 3 can be seen. For example, it is possible to recognize that the left direction indicator is blinking. Further, the left-pointing arrow Ya displayed on the momentary lever 3 is displayed in a medium size, so that it becomes easy to recognize the shape of the left-pointing arrow Ya even for a person or an elderly person who is difficult to see small characters or pictures.

  Further, if the left arrow Ya is set to the medium size and it is still difficult to see, the operation position of the switching knob 25 is switched from the medium size operation position to the large size operation position. It is assumed that the momentary lever 3 is tilted upward from the neutral position while the switching knob 25 is operated to the large size display position. At this time, the display control ECU 23 detects from the lever switch circuit 24 that the momentary lever 3 has been operated upward. At this time, the switch knob 25 is positioned at the large size display position from the knob switch circuit 26. Input a switch signal to the effect. Therefore, the display control ECU 23 recognizes that the large-size left arrow Ya should be displayed on the momentary lever 3, and turns on (or blinks) the third LED 21.

  When the third LED 21 is turned on, the third compartment 17 is illuminated by the third LED 21. At this time, the light of the third LED 21 is reflected by the half mirror 13c of the second mask film plate 13, so that most of the light is directed upward. Then, the light from the third LED 21 passes through the optical path 14 x of the third mask film plate 14, and this light reaches the back surface of the projection plate 22. Accordingly, the optical path 14x of the third mask film plate 14, that is, the image of the large left arrow Ya is projected onto the projection plate 22, and the left arrow Ya becomes very easy to see, which is effective in ensuring visibility. high.

  Therefore, in this example, by operating the switching knob 25, the display sizes of the arrows Ya and Yb displayed on the momentary lever 3 can be freely changed to the size desired by the operator. Further, even if a mechanism for switching the display sizes of the arrows Ya and Yb displayed on the momentary lever 3 is used as described above, this mechanism can switch the display size without using liquid crystal or expensive electronic components. Therefore, it is possible to reduce the cost of the parts for implementation.

  Therefore, if the display size of the display object such as the arrows Ya and Yb can be changed as in this example, for the elderly person or a person who is difficult to see small characters, Visibility is ensured even when the person is an operator. In addition, in the case of a person who is particular about the interior of the vehicle 1, there is a desire to reduce the size of this type of display, but in this example, this can also be dealt with and satisfy customer satisfaction. Furthermore, when this display unit 5 is applied to other in-vehicle switches, it is possible to increase the display size for those that are frequently used, and to reduce the display size for those that are not frequently used so that they are not noticeable. .

According to the configuration of the present embodiment, the following effects can be obtained.
(1) In this example, the display size of the arrows Ya and Yb displayed on the momentary lever 3 can be freely changed to the size desired by the operator without using expensive parts.

  (2) Since the half mirrors 12c to 14c are provided on the mask film plates 12 to 14, most of the light emitted by the lighting LED can be directed to the projection plate 22. Therefore, since the amount of light reaching the projection plate 22 increases, an image reflected on the projection plate 22 can be clearly displayed.

  (3) Each mask film plate 12 has a multi-layer structure, and a light transmitting portion 12a, a light shielding portion 12b and a half mirror 12c constituting the mask film plate 12 are integrally formed. Therefore, it is not necessary to assemble these parts one by one in the separate assembling process, and the number of processes required for the assembling work can be reduced. This is also true for the mask film plates 13 and 14.

  (4) If the display unit 5 of this example is adopted, the display object is not displayed when it is located at the neutral position, such as the momentary lever 3, and the display object is displayed when the lever is operated from the neutral position. It can be applied to such switches.

  (5) When the display unit 5 of this example is used for switches such as a switch for an in-vehicle air conditioner, when no light is emitted from the LEDs 19 to 21, no image is displayed on the surface of the projection plate 22, and the LED 19 When light is irradiated from ˜22, an image is displayed on the surface of the projection plate 22. Therefore, in the off state where the LEDs 19 to 22 do not irradiate light, no display body is displayed on the projection plate 22, and the satisfaction of a user who likes such a design can be satisfied.

In addition, this embodiment is not limited to the structure so far, You may change into the following aspects.
-Each division room 15-17 is not limited to being one room, and may be divided into a plurality of rooms in the plane direction. For example, as shown in FIGS. 4 and 5, by providing a cross-shaped dividing wall 41 inside the compartment 15 located at the lowest position in the direction in which the mask film plates 12 to 14 are juxtaposed, the compartment 15 A structure may be employed in which the chamber is divided into four divided compartments 15a to 15d. In this case, LEDs 19a to 19d are provided in the divided compartments 15a to 15d, respectively, and the first mask film plate 12 has optical paths of arrow shapes having different sizes at positions corresponding to the divided compartments 15a to 15d. 12xa to 12xd are formed. These optical paths 12xa to 12xd are arranged closer to the center position in the plane direction, so that when the image is projected onto the projection plate 22 with the light transmitted through the optical paths 12xa to 12xd, the light passes through the second mask film plate 13. And the situation where it is blocked by the third mask film plate 14 is less likely to occur. Therefore, if this structure is used, the size types of display objects that can be projected onto the projection plate 22 can be increased, and the satisfaction of the user can be improved.

  The arrangement order of the light transmitting portions 12a to 14a and the light shielding portions 12b to 14b of the mask film plates 12 to 14 having a multilayer structure is not limited to the light shielding portions 12b to 14b and the light transmitting portions 12a to 14a in this order from the top. As shown in FIG. 6, the order may be reversed so that the light transmitting portions 12 a to 14 a and the light shielding portions 12 b to 14 b are arranged from the upper side.

  -When providing the optical paths 12x-14x in the mask film plates 12-14, it is not limited to the structure which masks a black resin material as the light-shielding parts 12b-14b on the translucent parts 12a-14a. For example, as shown in FIG. 7, a concave portion 44 corresponding to a display object is punched and formed in a thin plate-shaped light-shielding portion 12b to 14b made of black resin, and a transparent resin is poured or left as it is. Accordingly, the structure may be such that the light transmitting portions 12a to 14a are formed.

  The switching of the display size of the display object (image) is not limited to being performed using the dedicated switching knob 25. For example, as shown in FIG. 8, a temperature mark 46 that appears when the engine switch is operated to ACC is provided on the in-vehicle temperature setting knob 45 that continuously switches the selected value, and the operation amount of the in-vehicle temperature setting knob 45 is The display size of the temperature mark 46 may be switched according to the above. In this case, for example, when the set temperature is low, the temperature mark 46 is displayed in a small size, and the temperature mark 46 is changed to a large size as the set temperature increases. Therefore, the display size of the display body can be changed also in this type of switches that are normally lit.

The display object whose display size is changed is not limited to the pattern such as the arrows Ya and Yb, but may be a character, for example.
-When changing the display size of the image displayed on the projection plate 22, it is not limited to three stages, and can be freely set in two stages or four or more stages.

  The operation means operated when switching the display size of the display object is not limited to the knob type using the switching knob 25. For example, a switch size may be provided for each of a small size, a medium size, and a large size, and a display size may be selected by pressing the switch button.

  The arrows Ya and Yb reflected on the momentary lever 3 are not limited to the configuration in which only the display size can be changed, and the color of the image can be changed by changing the color of the light emitted by the LEDs 19 to 21.

  -The design of the display objects (light paths 12x to 14x) formed on the mask film plates 12 to 14 arranged in the vertical direction is not limited to the same among the mask film plates 12 to 14, and each has a different design. It is good.

The light source is not limited to the LEDs 19 to 21 and is not particularly limited as long as it emits light in a diffused state such as a bulb.
-The display size variable display device of this example is not limited to the momentary lever 3 as long as it is another switch mounted on the vehicle. The display size variable display device is not limited to the on-vehicle switches, and may be applied to a switch group of an operation panel such as a video device, an audio, a digital camera, a telephone, a personal computer, or a printer.
