Moreover, the same switch can be used for multiple purposes by switching the display contents of both display devices.

〔Example〕

FIG. 1 is a vertical sectional view showing a switch with a display according to an embodiment of the present invention. FIG. 2 is a front view of the switch with an indicator of FIG. FIG. 3 is a diagram showing the inside of the bottom of the case of the first switch with an indicator.

The switch with indicator 20 of this embodiment includes a box-shaped holder 22 having an opening on the front surface (left side in FIG. 1), and a rectangular tube-shaped cover 24 fitted and fitted from the opening surface side thereof. Both are made of an insulating material and form a case 26.

In this case, in this example, a flexible printed circuit board 30 having a single-sided conductor wound on both front and back surfaces of a reinforcing plate 28 is arranged along the front surface of the case 26. The flexible printed circuit board 30 is bent in the case 26, and a part of the flexible printed circuit board 30 is passed through the space between the holder 22 and the back cover 224 thereof to come out from the rear surface of the case 26 for external connection. 32 is a connector.

Then, on the front side of the reinforcing plate 28, the segment type display 34
Is attached such that its front surface is along an inclined front surface portion of an operation cover 42 described later, and its terminals 341 are soldered to the flexible printed circuit board 30.

The segment type display 34 is, for example, a light emitting diode display (LED display), and can display a maximum of 5 digits as shown in FIG.

Further, a switch 36 such as a tact switch is attached to the rear surface side of the reinforcing plate 28 with its actuator 361 rearward, and its terminals are soldered to the flexible printed circuit board 30.

And, in the front part of the case 26, having two fitting pieces 421 rotatably and removably fitted to the two protruding shafts 241 respectively projected inward from the left and right sides of the cover 24, A translucent operation cover 42, which is rotatable in the front-rear direction as shown by an arrow A, is detachably fitted around the projecting shaft 241 as a spindle.

The operation cover 42 may be transparent or translucent, and may be colored, but translucent is preferable because the display contents of the segment type display 34 are easier to see.

It should be noted that the front portion of the operation cover 42 and the segment type display 34 in FIG. 1 are tilted upward because the upper side in FIG. This is because the operation cover 42 can be easily operated from diagonally above and the display content of the segment type display 34 can be easily seen from diagonally above, but it is not essential.

In the bottom of the case 26 (more specifically, in the holder 22 thereof), a lever-like movable piece 38 having elasticity which is bent in an inverted V shape when viewed from the side is housed. And holder
The support portion 221 provided on the bottom surface of 22 is used as a fulcrum of the movable piece 38, and the end portion on the long side thereof is used as a force point, and the projection portion 422 provided on the operation cover 42 serves as a point of arrow A of the operation cover 42. Depending on the pressing operation, such as pushing and releasing,
Further, accordingly, the operating mechanism of the switch 36 is configured by using the end portion of the movable piece 38 on the short side as an action point and pushing or releasing the actuator 361 of the switch 36 as indicated by arrow B there. ing. As shown in FIG. 3, the holder 22 is provided with an engaging portion 222 for preventing the floating of the movable piece 38 and an engaging portion 223 for preventing the movable piece 38 from popping out.

Further, in this embodiment, the reinforcing leaf spring 40 is provided on the back side of the movable piece 38.
If you do so, the movable piece 38 and the operation cover
It can increase the resilience of 42, but it is not essential.

On the other hand, a part of the front side of the operation cover 42 and avoiding the front of the segment type display 34, an opening 423 is provided in this embodiment, and a dot matrix type display 44 is provided on the rear surface thereof. It is attached by the holder 46. Further, a translucent window plate 48 is fitted into the opening 423.

Then, while connecting the flexible printed circuit board 50 to the dot matrix type display 44, bend the flexible printed circuit board 50 in the case 26 and pass a part of it through the space between the back lid 224 and the cover 24 to the outside of the rear surface of the case 26, It is designed to be used for external connection. 52 is a connector.

Therefore, in this example, the dot matrix type display 44 can move together with the operation cover 42, and the dot matrix type display 44 can be moved in this manner rather than fixing the dot matrix type display 44 separately from the operation cover 42. Is always on the front side, and the display contents are easy to see, which is preferable, but of course the dot matrix type display 44 is used for the case 26.
It may be fixed inside.

The dot matrix type display 44 is an electroluminescent display (EL display) in this example, and is formed by housing a display panel of, for example, 48 × 64 dots and its drive circuit in one case. Therefore, if 16 × 16 dots are assigned to one character, 12 characters can be displayed. In recent years,
Since a direct current low voltage (for example, DC30V or less) drive type EL display has been developed, it is preferable to use such a display.

A liquid crystal display may be used as the dot matrix type display 44, but an electroluminescent display has a wider viewing angle and is easier to see from an angle, and a self-luminous type that is easier to see even in a dark place. Is preferred.

Since the dot matrix type display 44 has a lower light emission intensity than the segment type display 34, the window plate 48 is preferably transparent or semi-transparent from the viewpoint of visibility.

Therefore, according to such a switch with display device 20, the dot matrix type display device 44 displays the destination, the product name, etc., and the corresponding charge etc. is displayed by the segment type display device 34.
By displaying the information on the destination, it is possible to display the destination, the product name and the like together with the charge and the like. Therefore, unlike the conventional switch 2 with a display that displays only numbers, the selection of the switch becomes easy.

Moreover, since the dot matrix type display 44 and the segment type display 34 both have electrically variable display contents,
By changing those control programs or the like, it is possible to change their display contents without much manual work. Therefore, unlike the conventional illuminated push-button switch 6 that changes the signage display plate 8, not only can it easily cope with price revisions, etc., but also with the indicator-equipped switch 10 previously proposed by the same applicant. Differently, it is possible to easily deal with changes in destinations and product names.

Moreover, the same switch (switch 20 with display) can be used for multiple purposes by switching the display contents of both displays 34 and 44. For example, in the automatic ticket vending machine, the same switch can be used to switch and display destinations and fares of different routes, which can reduce the number of switches.

Incidentally, the provision of the segment type display 34 is stopped,
There is also an idea to display both the destination and the charge on the dot matrix type display 44, but with the dot matrix type display, many dots are displayed when displaying complicated Kanji or displaying characters smoothly. It becomes necessary, the duty ratio of the drive signal becomes smaller, the display becomes darker, and if the peak value of the drive signal is raised too much in order to make it brighter, problems such as breakdown voltage of the element and heat generation at full lighting come out. The drive circuit of the dot matrix type display becomes complicated, wiring becomes difficult, and complicated software for displaying numbers is required, so if the number part is segmented, heat generation problems will occur. A bright display can be made without occurrence, the drive circuit is simple, and wiring is easy,
If both the segment type display 34 and the dot matrix type display 44, which can reduce the complexity of software, are provided, in the unlikely event of one failure, whether the destination (or product name) or the charge is charged. It is preferable to provide both the segment type display 34 and the dot matrix type display 44 as in this example for the reason that if either one is displayed, it can be used as it is.

In addition, instead of the reinforcing plate 28, a fixed printed circuit board (a rigid printed circuit board) is used, and a flexible printed circuit board 30 is used.
May be connected to pull out a part thereof to the outside of the case 26, or a fixed printed circuit board may be used in place of them to pull out a part thereof to the outside of the case 26. Similarly, when the dot matrix type display 44 is fixed in the case 26 unlike the above example, a fixed printed circuit board is used instead of the flexible printed circuit board 50 and a part of the fixed printed circuit board is pulled out of the case 26. May be.

Further, the operation cover 42 may be linearly movable (sliding) in the front-rear direction, instead of being rotatable as described above.

Further, the flexible printed circuit board 30 or the like is arranged in the case 26 along the front surface portion of the case 26 as in this embodiment, or is arranged along the front surface portion of the operation cover 42, and the flexible printed circuit board 30 or the like. Attaching the segment type display 34 and switch 36 on the front and back sides of
Since the space in the front-rear direction of the case 26 can be effectively used without waste such that the lengths of those terminal portions hardly affect the depth dimension, the depth dimension of the display-equipped switch 20 should be reduced. The effect that can be obtained is also obtained.

Further, when the operation mechanism of the switch 36 is configured by the movable piece 38 and the like as described above, the structure is simplified and the depth dimension is reduced.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

That is, since the dot matrix type display and the segment type display are provided, the display contents of both can be made to correspond to each other, and therefore, unlike the conventional switch with a display which only displays numerical values, the selection of the switch can be made. It will be easier.

Moreover, since the display contents of both indicators are electrically variable, the display contents can be changed electrically without much manual work. Unlike a button switch, it can easily respond to price revisions, etc., and unlike the switch with an indicator proposed by the same applicant, it can easily respond to changes in destination, product name, etc. be able to.

Moreover, the same switch can be used for multiple purposes by switching the display contents of both display devices.

Further, when the dot matrix type display is attached to the rear surface of the operation cover and moved together with it, the display is always positioned in the front, so that the display contents can be easily seen.

Further, when the dot matrix type display is an electroluminescent display, it has a wide viewing angle and is of a self-luminous type, so that the display contents are easy to see.
