Description

  The present invention relates to an input device that can be swung in first and second directions at least facing an operation lever.

  In this type of input device, a movable contact portion that swings in the same direction according to the swing of the operation lever in the first and second directions selectively contacts and conducts a plurality of fixed contact portions. Some of them are designed to detect the swing of the operation lever. In such an input device, since the movable contact portion is only selectively brought into contact with the fixed contact portion when the operation lever is swung, it is not possible to obtain an operational feeling of the operation lever swinging operation.

  There are first, second, and third input devices that can solve such problems. In the first input device, when the operating lever is swung by a predetermined angle or more, the protrusion provided on the lower end portion of the operating lever presses one arm portion of the torsion coil spring for generating the operational feeling, thereby operating the operating lever. A feeling of operation is generated in the swinging operation. In the second input device, when the operating lever is swung by a predetermined angle or more, one of a pair of operating feeling generating elastic members provided on the operating lever is supported by both of the bodies that hold the operating lever so as to be swingable. An operation feeling is generated in the swinging operation of the operation lever by elastically contacting one of the pair of convex portions for generating the operation feeling provided on the shoulder. The third input device includes a torsion coil spring for returning to the origin fitted on the swing shaft portion of the operation lever, a fixed portion through which the swing shaft portion passes, and the swing shaft portion connected to the swing shaft portion. And a movable portion that rotates together with the shaft portion. The torsion coil spring includes a first coil portion, a second coil portion that is reversely wound from the first coil portion, a connecting end that connects the first and second coil portions, and first and second first and second coil portions. 2 free ends. When the operation lever is swung, the upper part of the stepped portion of the movable portion rotates according to the swinging of the operation lever to press the first or second free end, and the operation lever is swung by a predetermined angle or more. When the lower part of the step part of the movable part presses the second or first free end, an operation feeling is generated in the swing operation of the operation lever.

  However, since the torsion coil spring for generating operational feeling is indispensable for the first input device, the number of parts increases, and it takes time to incorporate the torsion coil spring. Moreover, since it is necessary to provide the installation space of the said torsion coil spring which is another component in a 1st input device, a 1st input device enlarges. Since the elastic member for generating the operational feeling is indispensable for the second input device, the cost is increased and the device is enlarged as in the case of the first input device.

  Although the third input device uses a torsion coil spring for returning the origin of the operation lever, the torsion coil spring has two coil portions. That is, since the torsion coil spring for returning to origin has a configuration in which two torsion coil springs are connected, the length of the torsion coil spring for returning to origin is increased, and the installation space is also increased. Therefore, the third input device is also enlarged.

  The present invention was devised in view of the above circumstances, and an object of the present invention is to generate an operational feeling in the swinging operation of the operation lever, and to reduce the cost and size of the apparatus. An object of the present invention is to provide an input device that can be used.

In order to solve the above-described problems, an input device according to the present invention includes an operation lever capable of swinging in first and second directions facing at least a predetermined origin position, and an urging force for holding the operation lever at the origin position Means and movement detection means for detecting the swing of the operation lever. The biasing means includes a coil portion and first and second support arms extending in two opposite directions from the first and second ends of the coil portion . The operation lever extends in the first and second directions and is elastically supported by the first and second support arms from opposite sides of the first and second directions. Two swing arms, and first and second pressing portions disposed on the first and second direction sides of the first and second support arms, spaced apart from the first and second support arms. ing. When the operation lever is swung in the first direction, the first swing arm is swung in the first direction, and the first support arm is displaced by pressing the first support arm. The coil portion is compressed, the second swing arm swings in the first direction and moves away from the second support arm, and the second pressing portion approaches the second support arm, and the operation When the lever is swung in the first direction by a predetermined angle or more, the second pressing portion comes closer to the second support arm, presses the second support arm, and displaces the coil portion. It is designed to be compressed. When the operation lever is swung in the second direction, the second swing arm swings in the second direction, and the second support arm is displaced by pressing the second support arm. The coil portion is compressed, the first swing arm swings in the second direction and moves away from the first support arm, and the first pressing portion approaches the first support arm, and the operation When the lever is swung in the second direction by a predetermined angle or more, the first pressing portion further approaches the first support arm, presses the first support arm, and displaces the coil portion. It is designed to be compressed.

  In the case of such an input device, when the operation lever is swung in the second and first directions by a predetermined angle or more, the first and second pressing portions move the first and second support arms of the urging means. Thus, an operation feeling is generated in the swinging operation of the operation lever in the second and first directions. That is, the urging means for returning to the origin and the first and second pressing portions of the operation lever provide an operational feeling in the swinging operation of the operation lever, thereby suppressing an increase in the number of parts. Thus, the cost of the input device can be reduced.

Therefore, a large installation space is not required for the urging means. Therefore, the size of the input device can be reduced. Further, when the operation lever swings in the second and first directions by a predetermined angle or more, the first and second pressing portions of the operation lever press the first and second support arms of the biasing means. Since the operation feeling is generated, the return movement of the operation lever to the origin position is not hindered by the configuration. Further, since the operation feeling is generated by using the urging means for returning to the origin and the first and second pressing portions of the operation lever, the operation feeling generation timing and the movement detection timing of the movement detection means are detected. Can be easily adjusted.

The input device may further include a body having a plate portion. In this case, it is possible to provide the plate portion with a convex swing shaft portion inserted into the coil portion, and to provide the operation lever with a shaft hole into which the swing shaft portion is inserted.

  When the movement detection unit is capable of detecting the swing of the first predetermined angle of the operation lever, the movement detection unit includes a plurality of first fixed contact portions provided on the plate portion of the body, And a movable contact portion that is provided on a surface of the operation lever facing the plate portion and swings in accordance with the swing of the operation lever. The movable contact portion has a pair of first contact portions that selectively come into contact with the first fixed contact portion according to the swing of the operation lever at a first predetermined angle.

It further has a contact part. The movable contact portion further includes a second contact portion. When the operation lever is swung by a second predetermined angle, the first contact portion selectively contacts the first fixed contact portion, and the second contact portion selectively contacts the second fixed contact portion. It comes to contact.

  The input device may further include an internal substrate disposed on the plate portion of the body. In this case, the first fixed contact portion, or the first and second fixed contact portions are provided not on the plate portion of the body but on the internal substrate.

The operation lever can be pressed from the origin position. In this case, the movement detecting means also detects a pressing movement of the operation lever.
Another input device of the present invention can be operated to swing in the first and second directions relative to a predetermined origin position, and can be operated to be pressed from the origin position, and the operation lever can be used as the origin position. There is provided an urging means for holding in position, a movement detecting means for detecting swinging of the operating lever and a pressing movement of the operating lever, and a body having a plate portion. The biasing means has first and second support arms extending in two opposite directions. The operation lever extends in the first and second directions and is elastically supported by the first and second support arms from opposite sides of the first and second directions. Two swing arms, and first and second pressing portions disposed on the first and second direction sides of the first and second support arms, spaced apart from the first and second support arms. ing.

The arms 112d and 112e are locked. Thereafter, the locking pieces 222 and 223 of the frame 220 are locked to the locking recesses 213 b and 213 c of the body 210, and the frame 220 is attached to the body 210. As a result, the cover portion 221 of the frame 220 closes the accommodation space of the body 210.

  Hereinafter, the usage method and the operation of the input device assembled in this way will be described. As shown in FIG. 5B, when the operating lever 100 is operated to swing by a predetermined angle in the first swinging direction α1, the operating lever 100 swings first with the swinging shaft portion 212 of the body 210 as a fulcrum. Swings in direction α1. In both cases, as shown in FIG. 6B, the movable contact portion 410 rotates in the first swinging direction α1, and the pair of contact portions 413 of the movable contact portion 410 are contact portions 421a of the fixed contact portions 421 and 422. 422a to make the fixed contact portions 421 and 422 conductive. Thereby, the swing of the operation lever 100 at a predetermined angle in the first swing direction α1 is detected.

  At this time, the first swing arm 112d of the operation lever 100 presses the first support arm 320 of the torsion coil spring 300 downward, thereby compressing the coil portion 310. On the other hand, the second pressing portion 112h of the operation lever 100 approaches the second support arm 330 of the torsion coil spring 300 and presses the second support arm 330 upward, thereby also compressing the coil portion 310. In both cases, the concave portion 112a of the operating lever 100 and the first and second convex portions 112b and 112c are swung in the same direction, and the second convex portion 112c rides on the projection 221a of the frame 220 detached from the concave portion 112a. The cover portion 221 of the frame 220 is elastically deformed. By the above-described pressing of the second support arm 330 of the second pressing portion 112h and sliding on the protrusion 221a of the second convex portion 112c, the operation lever 100 can be swung more than a predetermined angle in the first swinging direction α1. A feeling of operation is given.

  Thereafter, when the operation lever 100 is released, the first support arm 320 presses the first swing arm 112d of the operation lever 100 upward by the biasing force of the coil portion 310 of the torsion coil spring 300, and the second support arm. 330 presses the second pressing portion 112h of the operation lever 100 downward. As a result, the operating lever 100 swings in the second swing direction α2 with the swing shaft portion 212 of the body 210 as a fulcrum, and returns to the origin position.

  As shown in FIG. 5C, when the operating lever 100 is swung up to the maximum angle in the first swing direction α1, as shown in FIG. Reference numeral 413 contacts the contact portions 421a and 422a of the fixed contact portions 421 and 422, and the contact portion 414 contacts the contact portion 425a of the fixed contact portion 425, thereby making the fixed contact portions 421 and 425 conductive. As a result, the maximum swing of the operation lever 100 in the first swing direction α1 is detected. Other than that, the operation lever 100 is the same as that when the operation lever 100 is swung by the predetermined angle in the first swing direction α1, and the description thereof is omitted.

  When the operation lever 100 is swung by a predetermined angle in the second swing direction α2, the operation lever 100 swings in the second swing direction α2 with the swing shaft portion 212 of the body 210 as a fulcrum. In both cases, the movable contact portion 410 rotates in the second swing direction α2, the pair of contact portions 413 of the movable contact portion 410 contact the contact portions 421a and 423a of the fixed contact portions 421 and 423, and the fixed contact portion. 421 and 423 are made conductive. Thereby, the swing of the operation lever 100 at a predetermined angle in the second swing direction α2 is detected.

  At this time, the second swing arm 112e of the operation lever 100 presses the second support arm 330 of the torsion coil spring 300 downward, whereby the coil portion 310 is compressed. On the other hand, the first pressing portion 112g of the operating lever 100 approaches the first support arm 320 of the torsion coil spring 300 and presses the first support arm 320 upward, thereby also compressing the coil portion 310. In both cases, the concave portion 112a of the operating lever 100 and the first and second convex portions 112b and 112c swing in the same direction, and the first convex portion 112b rides on the projection 221a of the frame 220 that is detached from the concave portion 112a. The cover portion 221 of the frame 220 is elastically deformed. By the above-described pressing of the first support arm 320 of the first pressing portion 112g and sliding on the protrusion 221a of the first convex portion 112b, the operation lever 100 can be swung more than a predetermined angle in the second swinging direction α2. A feeling of operation is given.

  Thereafter, when the operation lever 100 is released, the second support arm 330 presses the second swing arm 112e of the operation lever 100 upward by the biasing force of the coil portion 310 of the torsion coil spring 300, and the first support arm. 320 presses the first pressing portion 112g of the operation lever 100 downward. As a result, the operating lever 100 swings in the first swinging direction α1 with the swinging shaft portion 212 of the body 210 as a fulcrum, and returns to the origin position.

  When the operation lever 100 is swung up to the maximum angle in the second swinging direction α2, the pair of contact portions 413 of the movable contact portion 410 comes into contact with the contact portions 421a and 423a of the fixed contact portions 421 and 423, and contact is made. The part 414 contacts the contact part 424a of the fixed contact part 424, and the fixed contact parts 421 and 424 are made conductive. Other than that, the operation lever 100 is the same as when the operation lever 100 is operated to swing by a predetermined angle in the second swing direction α2, and therefore the description thereof is omitted.

  In the case of the input device as described above, the first and second operation feeling generating means gives an operation feeling to the swing operation of the operation lever 100 in the first and second swing directions α1 and α2 by a predetermined angle or more. It has come to occur. The second operational feeling generating means includes a torsion coil spring 300 for returning to the origin and the first and second pressing portions 112g and 112g of the operating lever 100, and the first operational feeling generating means is the operating lever.
