Therefore, the destination floor button device for designating the first floor as the destination floor will be described as a representative, and the description of other operation button devices will be omitted.

First, prior to the description of the operation button device 100 (FIGS. 4A, 5, 6, 7, and 8A) according to the embodiment, a standard operation button device having a basic configuration as an operation button device. The configuration of 200 will be described.

FIG. 4B is a front view of the standard operation button device 200. FIG. 10 is a sectional view taken along line BB in FIG. 4 (b). FIG. 11 is a partially exploded perspective view of the standard operation button device 200. FIG. 8B is a circuit diagram showing an outline of the circuit configuration of the standard operation button device 200.

The standard operation button device 200 has a first case member 202 and a second case member 204. The first case member 202 has a box shape, and a circuit board 206 is provided at the bottom thereof. A photoelectric sensor 208 is mounted on the circuit board 206. Details of the photoelectric sensor 208 will be described later.

The switch body 212 of the tactile switch 210 is also mounted on the circuit board 206 as a mechanical switch. The switch body 212 has a fixed contact 214 and a movable contact 216 (not shown in FIGS. 10 and 11), and as shown in FIG. 8 (b), the switch body 212 closes when an "ON" operation is performed and opens when an "OFF" operation is performed. It is an a-contact (make contact) type switch.

The tactile switch 210 also has an actuator 218 for displacing the movable contact 210. The actuator 218 is composed of a hollow member having an annular shape as a whole. The actuator 218 has a spring seat 218a, as shown in FIG.

A compression spring 220 is provided as an elastic member between the spring seat 218a and the bottom of the first case member 202. One end of the compression spring 220 is fixed to the bottom of the first case member 202, and the other end is fixed to the spring seat 218a. As a result, the actuator 218 is attached to the first case member 202 via the compression spring 220. The compression spring 220 is in a free length state as shown in FIG.

The standard operation button device 200 also has a push button 222. The push button 222 includes a main body 224, a display board 226, and a translucent cover 228.

The main body 224 has a petri dish shape as a whole having a circular bottom portion 224a and a cylindrical portion 224b rising from the outer peripheral portion of the bottom portion 224a, and a window (hollow portion) 224c is opened in the bottom portion 224a.

The translucent cover 228 is made of a material that transmits the detection light described later of the photoelectric sensor 208. The translucent cover 228 has a shape that matches the window 224a, and is fixed to the window 224a with an adhesive or the like so as to close the window 224a.

The display plate 226 is made of synthetic resin and has a display portion 226b composed of a plate-shaped substrate 226a and a convex portion protruding from the substrate 226a. The front view shape of the display unit 226b is formed as "1" as shown in FIG. 4 (b). The shape of the display unit 226b is changed according to the use of the standard operation button device 200. Since this example is a standard operation button device 200 (destination floor button device) that designates the first floor as the destination floor, the shape of the display unit 226b is "1". The display unit of the destination floor button device whose target floor is the 2nd to 5th floors has the shape of "2" to "5", respectively. Further, in the case of the door open button device 48 and the door close button device 50, the shape is as shown in FIG. 3 (a), and the external contact button device 52 is in the shape of a handset (FIG. 3 (a). In the case of the upper button device 56 and the lower button device 58, the shape is a triangle (FIG. 3 (b)).

The display plate 226 has a window (hollow portion) 226c. The display plate 226 also has a pair of facing claw portions 226d and 226e. The display plate 226 is fixed to the bottom surface of the bottom portion 224a of the main body 224 with an adhesive or the like.

As described above, the main body 224, the display plate 226, and the translucent cover 226 are fixed to each other with an adhesive or the like to be integrated, and the push button 222 is configured by these.

The actuator 218 is formed with engaging portions 218b and 218c that engage with each of the claw portions 226d and 226e. The push button 222 causes the claw portions 226d and 226e to enter the hollow portion of the annular actuator 218, and engages each of the claw portions 226d and 226e with the engaging portions 218b and 218c, thereby engaging the actuating portion 218. It will be installed. The state after mounting is shown in FIG.

Further, the pair of claw portions 226d and 226e are bent so as to approach each other to disengage the engagement with the engaging portions 218b and 218c, and the push button 22 is retracted in the direction opposite to the approach to push the push button. The 222 is detached from the actuator 218. That is, the push button 222 is detachably provided with respect to the actuator 218.

The second case member 204 is attached to the first case member 202 with the push button 222 attached to the actuator 218. The second case member 204 has a short cylindrical portion 204a, as shown in FIG. The inner diameter of the cylindrical portion 204a is set to be slightly larger than the outer diameter of the cylindrical portion 224b in the main body 224 of the push button 222. The second case member 204 is attached to the first case member 202 so that the cylinder 204a is externally inserted into the cylindrical portion 224b of the button 222.

In the configuration described so far, when the operation surface 222a including the outer bottom surface of the bottom 224a of the main body 224 of the push button 222 and the surface of the translucent cover 228 is pressed with a fingertip or the like, the actuator 218 is pressed by the push button 222. It is displaced in the direction of pressing and the tactile switch 210 is turned on. At this time, the compression spring 220 is compressed. Further, when the fingertip or the like is separated from the operation surface 222a, the actuating element 218 and the push button 222 are displaced and restored to their original positions by the restoring force of the compression spring 220, and the tactile switch 210 is turned off.

At this time, the cylindrical portion 204a of the second case member 204 functions as a guide member for the cylindrical portion 224b of the push button 222, and the smooth advance / retreat operation of the push button 222 is ensured.

An LED element for lighting (not shown) is mounted on the circuit board 206, and when the tactile switch 210 is turned on, the LED element emits light. By illuminating the display unit 226b of the display board 226 with the light from the LED element, the user can recognize that a predetermined operation for the standard button device 200 has been accepted. Further, for example, in the case of the destination floor button device 46, the LED element is turned off when the car 22 lands on the destination floor.

In addition to the tactile switch 210, which is a mechanical switch, the standard operation button device 200 includes a photoelectric sensor 208 as a non-contact sensor that accepts user operations in a non-contact manner.

The photoelectric sensor 208 is a known limited reflection type photoelectric sensor, and has a light emitting unit 208a and a light receiving unit 208b as shown in FIG. The light projecting unit 208a includes a light emitting element that emits infrared light and a lens (both not shown) that collects infrared light from the light emitting element to form a light emitting beam (detection light). The light receiving unit 208b includes a light receiving element and a lens (both not shown) that collects light entering from a predetermined light receiving area on the light receiving element.

The photoelectric sensor 208 thus has an optical system that limits the projection beam (detection light) and the light receiving area, and extends over a certain distance range (the overlapping range of the projection beam and the light receiving area) from the photoelectric sensor 208. The configuration is such that a finger or other object (detection object) in the detection area is detected. That is, when the detected object is in the detection region, the detected light (reflected light) reflected by the detected object is incident on the light receiving unit 208b to detect the detected object. The detected light and the reflected light enter and exit the photoelectric sensor 208 through the window 224c, the window 226c, and the translucent cover 226.

The detection region D will be described with reference to FIG. In FIG. 10, the left-right direction will be described as the horizontal direction. As the photoelectric sensor 208, the detection region D is a region extending from a position separated by a predetermined distance La1 in the horizontal direction to a position separated by a predetermined distance La2 from the emission position 208c of the detection light. The region from the emission position 208c to the distance La1 is a non-detection region (hereinafter, referred to as “non-detection region LA1”) in which the detected object is not detected. In FIG. 10, a region surrounded by a two-dot chain line and drawn with a dashed diagonal line is a detection region D.

Considering the operation surface 222a as a reference in the specifications of the standard operation button device 200, the detection area D is a region extending from a position separated by a predetermined distance Lb1 to a position separated by a predetermined distance Lb2 from the operation surface 222a as a starting point. The region from the operation surface 222a to the predetermined distance Lb1 is a non-detection region (hereinafter, referred to as “non-detection region LB1”) in which the detected object is not detected. That is, the operation surface 222a exists in the non-detection region LA1 of the photoelectric sensor 208.

The distance Lb1 of the non-detection region LB1 is set to, for example, 30 mm. Further, the distance Lb2 is set to, for example, 100 mm. Therefore, the horizontal length of the detection region D is 70 mm in this example.

In the standard operation button device 200, the non-detection area LB1 is set when a visually impaired user searches for the position of the push button 222 by fumbling, and the standard operation other than aiming at the user's finger or the like is performed. This is to prevent the photoelectric sensor 208 of the button device 200 (for example, the destination floor button device 52) from reacting and erroneously registering the target floor.

As described in [Problems to be Solved by the Invention], there is a request to change and adjust the start position of the detection region D from the operation surface 222a of the push button 222, that is, the distance Lb1, in particular, to shorten the adjustment.

In this case, the distance La1 and thus the distance Lb1 can be adjusted (shortened) by adjusting the optical system of the photoelectric sensor 208. However, this requires skill such as delicate adjustment of the optical axis of the lens (not shown).

Therefore, the inventor of the present application has developed an operation button device 100 capable of easily adjusting the start position (distance Lb1) of the detection region D from the operation surface 222a of the push button 222 without requiring adjustment of the photoelectric sensor 208 or the like. did.

FIG. 4A is a front view of the operation button device 100. FIG. 5 is a cross-sectional view taken along the line AA in FIG. 4A. FIG. 6 is a partially exploded perspective view of the operation button device 10. 7 (a) is a front view of the interval adjustment adapter 150, FIG. 7 (b) is a plan view, FIG. 7 (c) is a right side view, and FIG. 7 (d) is C in FIG. 7 (a). -C-line cross-sectional views are shown respectively. FIG. 7 (e) is a perspective view of the spacing adjustment adapter 150. Since the left side view of the spacing adjustment adapter 150 appears in the same manner as the right side view and the bottom view appears in the same manner as the plan view, the illustration is omitted. FIG. 8A is a circuit diagram showing an outline of the circuit configuration of the operation button device 100.

The operation button device 100 has basically the same configuration as the operation button device 200 except that it has the interval adjustment adapter 150. Therefore, the components of the operation button device 100 are designated by the reference numerals in the hundreds, and the components similar to the operation button device 200 are designated by the same reference numerals in the last two digits, and the description thereof will be omitted. Or, I will only mention it as appropriate, and I will mainly explain the different parts below.

In the standard operation button device 200, the pressing operation of the push button 222 is directly transmitted to the actuator 218, and the actuator 218 is displaced in the pressing direction. However, in the operation button device 100, the pressing of the push button 122 is performed. The operation is transmitted to the actuator 118 via the interval adjustment adapter 150, and the actuator 118 is displaced in the push-button direction.

As shown in FIG. 7, the interval adjustment adapter 150 has a disc-shaped disc portion 154 having a square window (hollow portion) 152 and a short cylindrical shape protruding from one main surface of the disc portion 154. It has a main body portion 158 including a portion 156.

At two locations of the tubular portion 156, engaging portions 156a and 156b having the same shape as the engaging portions 218b and 218c (FIG. 10) of the actuator 218 are formed.

Further, a claw portion 154a and 154b having the same shape as the claw portion 226d and 226e (FIG. 10) of the display plate 226 are provided so as to project from the other main surface of the disk portion 154. The main body portion 158 has a predetermined height T.

The spacing adapter 150 is provided between the pushbutton 122 and the actuator 118, as shown in FIG. The claw portions 154a and 154b of the spacing adjustment adapter 150 are engaged with each of the engaging portions 118b and 118c of the actuator 118, respectively, and the spacing adjusting adapter 150 is attached to the actuator 118. The interval adjustment adapter 150 is detachably provided on the actuator 118 as in the case of the actuator 218 and the push button 222 in the standard operation button device 200.

The claws 126d and 126e of the push button 122 are engaged with each of the engaging portions 156a and 156b of the spacing adjusting adapter 150, respectively, and the push button 122 is attached to the spacing adjusting adapter 150. The interval adjustment adapter 150 is detachably provided on the push button 112 as in the case of the actuator 218 and the push button 222 in the standard operation button device 200.

By providing (inserting) the spacing adjustment adapter 150 between the push button 122 and the actuator 118 in this way, the spacing between the push button 122 and the actuator 118 is adjusted. Specifically, in the case of the standard operation button device 200, where there is no gap between the push button 222 and the actuator 228, by providing the interval adjustment adapter 150, the push button 122 and the actuator 118 are provided in the operation button device 100. The interval is adjusted to the height T of the main body portion 158.

As a result, the horizontal distance from the actuator 118 to the operation surface 122a of the push button 122, and by extension, the distance from the photoelectric sensor 108 to the operation surface 122a has been shortened by the adjusted interval (height T). Become.

In the operation button device 100, the region extending from the position separated by the predetermined distance Lc1 from the operation surface 122a to the position separated by the predetermined distance Lc2 is the detection area D. The region from the operation surface 122a to the predetermined distance Lc1 is a non-detection region (hereinafter, referred to as “non-detection region LC1”) in which the detected object is not detected.

A comparison of the distance of the detection area D of the operation button device 100 from the operation surface 122a and the distance of the detection area D of the standard operation button device 200 from the operation surface 222a is as follows.

The distance Lc1 from the operation surface 122a of the non-detection region LC1 is the standard operation button device 200.
The height T of the non-detection region LB1 in the non-detection region LB1 is shorter than the distance Lb1 from the operation surface 222a.

The horizontal length of the cylindrical portion 160a of the second case member 160 of the operation button device 100 is the amount that the operation surface 122a is separated from the actuator 118 (height T), and the standard operation button device 200 is the first. 2 It is longer than the cylindrical portion 204a of the case member 204.

As described above, the operation button device 100 according to the embodiment has a simple configuration in which an interval adjusting adapter 150 is provided between the push button 122 and the actuator 118, from the operation surface 122a of the push button 122 of the photoelectric sensor 108. The start position (distance Lc1) of can be changed.

Moreover, since the spacing adjustment adapter 150 is detachably provided for both the actuator 118 and the push button 122, it can be easily assembled. Therefore, a plurality of interval adjustment adapters 150 having different heights T are prepared, and one of which the distance Lc1 of the detection region D from the operation surface 122a is a desired length is selected and operated with the push button 122.
