Although details are omitted for the upper half 27, the front end of the upper half 27 (the side from which the USB cable 4 is pulled out) is supported in a swingable manner in a cantilevered state, and has a substantially identical surface. The left click operation member 14 and the right click operation member 16 are provided side by side. The left click operation member 14 and the right click operation member 16 open and close the left click switch 15 or the right click switch 17 including a tact switch or the like by being pressed as described above.

  As shown in FIG. 2, the mouse 1 is positioned between the left click operation member 14 and the right click operation member 16 in the upper half 27 and guides a part of the outer peripheral portion of the scroll dial 21 to the outside. An opening 29 is formed. The guide opening 29 is formed to have an opening width larger than the thickness of the scroll dial 21, and allows the scroll dial 21 to be slid in the left-right direction within the range of the opening width.

  As shown in FIGS. 3 and 4, the mouse 1 is provided with a first bearing portion 30 and a second bearing portion 31 that are opposed to the inner surface of the lower half 28 with the guide opening 29 interposed therebetween. The mouse 1 supports the scroll dial spindle 22 having a longer axis than the lateral width of the guide opening 29 by the first bearing portion 30 and the second bearing portion 31 so as to be rotatable and slidable. The first bearing portion 30 includes a first bearing plate 32 that rotatably supports the scroll dial support shaft 22 fixed in the axial direction, and the first bearing plate 32 that stands upright and is formed on the inner surface of the lower half 28. The base plate 33 is provided so as to be slidable in the axial direction by a guide convex portion 34 (see FIG. 4) that omits the details.

  The first bearing portion 30 is rotatably supported by passing one end side of the scroll dial support shaft 22 through a shaft hole formed in the first bearing plate 32, and the first bearing plate is supported on the scroll dial support shaft 22. It is fixed in the axial direction by a pair of stoppers 35A and 35B having a diameter larger than that of the shaft hole fixed with the pin 32 interposed therebetween. As shown in FIGS. 3 and 4, the first bearing portion 30 has tension springs 36 </ b> A and 36 </ b> B with one end fixed to the side edge in the length direction of the base plate 33 and the other end fixed to the lower half 28. The base plate 33 is held at the neutral position at a position where the elastic forces of the springs 36A and 36B are balanced. The first bearing portion 30 is arranged such that the scroll dial 21 is positioned in the center with respect to the left-right direction in the guide opening 29 as shown in FIG. 4 with the base plate 33 held in the neutral position. .

  In the mouse 1, an encoder plate 23 is fixed to an end portion of the scroll dial support shaft 22 penetrating the shaft hole of the first bearing plate 32, and rotates integrally with the rotation of the scroll dial support shaft 22. Although not described in detail, the encoder plate 23 is formed with a large number of reflecting portions and low reflecting portions arranged in the circumferential direction on the outer side surface, and these reflecting portions and the low reflecting portions are the rotation detection sensor 24. Detected by.

  In the first bearing portion 30, a first sensor mounting column portion 37 that is positioned on the side opposite to the first bearing plate 32 and faces the encoder plate 23 is integrally provided on the base plate 33. The rotation detection sensor 24 is attached to the first sensor attachment column portion 37 on the surface facing the encoder plate 23. Although not described in detail, the rotation detection sensor 24 includes a light emitting element that emits detection light toward the rotation detection sensor 24 and a light receiving element that receives the detection light reflected by the rotation detection sensor 24. The rotation detection sensor 24 outputs a pulse signal to the first scroll signal output unit 19 based on detection light in which the amount of reflected light is different between the reflection unit and the low reflection unit.

  Since the rotation detection sensor 24 is mounted on the base plate 33 as described above, even if the scroll dial support shaft 22 slides in the axial direction by a slide operation of the scroll dial 21 described later, the detection operation is hindered. There is nothing. In addition, the rotation detection sensor 24 is not limited to the above-described configuration. For example, an encoder plate 23 in which a large number of slits are arranged in the circumferential direction, and a light emitting element and a light receiving element arranged with the encoder plate 23 interposed therebetween. You may make it comprise by. The rotation detection sensor 24 outputs a pulse signal to the first scroll signal output unit 19 when the light receiving element detects the detection light emitted from the light emitting element and passing through the slit by the rotation of the encoder plate 23.

  As shown in FIGS. 3 and 4, the second bearing portion 31 is composed of a second bearing plate 38 that stands integrally with the lower half 28 so as to face the first bearing plate 32 of the first bearing portion 30 described above. . As shown in FIG. 3, the second bearing portion 31 has a U-shape that is open at the upper end and has a shaft hole that is aligned with the shaft hole of the first bearing plate 32. The The second bearing portion 31 supports the end portion of the scroll dial support shaft 22 by the second bearing plate 38 so as to be rotatable and slidable.

  A scroll dial 21 is fixed to the scroll dial spindle 22 at a substantially central portion in the length direction. A large number of markers 25 are formed on the scroll dial support shaft 22 in the region between the scroll dial 21 and the first bearing plate 32 in the axial direction. The marker 25 is constituted by, for example, a large number of optical slits formed on the scroll dial support shaft 22 in the axial direction with a predetermined interval. The marker 25 detects the operation direction and the operation amount of the scroll dial support shaft 22 by detecting these optical slits by the slide detection sensor 26 along with the slide operation of the scroll dial support shaft 22 in the axial direction. To.

  The slide detection sensor 26 is attached to a second sensor attachment column portion 39 that is positioned between the scroll dial 21 and the first bearing plate 32 and is erected integrally with the lower half 28. As shown in FIG. 3, the second sensor mounting column portion 39 is formed in a bifurcated shape with the upper end portion sandwiching the scroll dial support shaft 22, and a light emitting element is mounted on one side and a light receiving element is mounted on the other side. The slide detection sensor 26 allows detection light emitted from the light emitting element to be received by the light receiving element by passing through each marker 25 formed on the scroll dial support shaft 22. In the slide detection sensor 26, the detection light emitted from the light emitting element is reflected by the scroll dial support shaft 22 at a position deviated from each marker 25, so that the light receiving element does not receive light. The slide detection sensor 26 outputs a pulse signal to the second scroll signal output unit 20 based on the light receiving state of the detection light in the light receiving element.

  The slide detection sensor 26 may have a structure for detecting the detection light reflected by the scroll dial spindle 22 as well as the structure for detecting the detection light passing through the scroll dial spindle 22 described above. The slide detection sensor 26 includes a light emitting element and a light receiving element disposed along the outer periphery of the scroll dial support shaft 22, and a large number of the slide detection sensors 26 are formed side by side in the axial direction with a predetermined interval. The marker 25 constituted by the reflective portion and the low reflective portion is detected. The second sensor mounting column portion 39 does not need to have a bifurcated shape with the upper end portion sandwiching the scroll dial spindle 22.

  The scroll dial spindle 22 is supported by the first bearing portion 30 and the second bearing portion 31 described above so as to be rotatable and slidable in the axial direction. A scroll dial 21 is fixed to the scroll dial spindle 22 at the central portion in the axial direction. As described above, a part of the outer peripheral portion of the scroll dial 21 extends from the upper half 27 via the guide opening 29. To be exposed. As described above, the scroll dial 21 is positioned at the center in the width direction in the guide opening 29 because the first bearing portion 30 holds the base plate 33 in the neutral position by the pair of tension springs 36A and 36B. To do. Accordingly, the scroll dial 21 is rotatable in the guide opening 29 and is slidable in the left-right direction within the length range of the guide opening 29 in the width direction.

  When the scroll dial 21 is rotated, the scroll dial support shaft 22 and the encoder plate 23 are rotated together. Therefore, when the scroll dial 21 is rotated counterclockwise in FIG. 3, the first scroll signal output unit 19 outputs an upward scroll signal. Further, when the scroll dial 21 is rotated in the clockwise direction in the figure, a downward scroll signal is output from the first scroll signal output unit 19.

  On the other hand, the scroll dial 21 is slid in the left direction integrally with the scroll dial support shaft 22 when the user slides leftward in FIG. 4 from the neutral position in the guide opening 29 by the fingertip. . The scroll dial 21 causes the scroll dial support shaft 22 to slide while compressing the outer tension spring 36A to store the repulsive force and to store the elastic force in the inner tension spring 36B. The scroll dial 21 outputs a scroll signal in the left direction from the second scroll signal output unit 20 so that the marker 25 is detected by the slide detection sensor 26 as the scroll dial spindle 22 slides.

  Further, the scroll dial 21 is slid in the right direction integrally with the scroll dial support shaft 22 when the user slides the guide dial 29 in the guide opening 29 from the neutral position to the right in FIG. . The scroll dial 21 causes the scroll dial support shaft 22 to slide while compressing the inner tension spring 36B to store the repulsive force and to store the elastic force in the outer tension spring 36A. The scroll dial 21 outputs a scroll signal in the right direction from the second scroll signal output unit 20 so that the marker 25 is detected by the slide detection sensor 26 as the scroll dial spindle 22 slides.

  The scroll dial 21 returns to the neutral position when the user releases the fingertip while being slid leftward or rightward. The scroll dial 21 is stored in a guide opening via the scroll dial support shaft 22 by the elastic force of the tension springs 36A, 36B in which the repulsive force is stored by being compressed and the tensile elastic force is stored by being stretched. Return to the neutral position in the part 29.

  By the way, in the mouse 1, the display screen of the monitor 3 is scrolled by the left / right sliding operation of the scroll dial 21, and the second scroll is performed when the scroll dial 21 returns to the neutral position while the predetermined screen is displayed. The screen displayed when the signal output unit 20 outputs the scroll signal in the return direction is restored. Therefore, the mouse 1 is adapted to cut the scroll signal output when the scroll dial 21 is restored.

In the mouse 1, for example, the marker 40 shown in FIG. 5 is formed on the scroll dial spindle 22, and the detection signal from the slide detection sensor 26 that detects the marker 40 is processed by software to perform the sliding operation of the scroll dial 21. Ensure that direction detection is performed. The marker 40 is composed of a high reflection portion obtained by joining an aluminum foil formed along the axial direction to the scroll dial support shaft 22 in a strip shape and a strip-shaped low reflection portion in the background portion. The marker 40 is formed at a neutral position marker 41 having a slightly wider width at which the slide detection sensor 26 is opposed to the neutral position of the scroll dial 21, a left slide marker 42 formed on the right side of the neutral position marker 41, and a left side. The right slide marker 43, and the left slide marker 42 and the left individual markers 44a to 44n and the right individual markers 45a to 45n formed on both sides of the right slide marker 43, respectively.

  In the mouse 1, the neutral position marker 41 is detected by the slide detection sensor 26 while the scroll dial 21 is in the neutral position. In the mouse 1, the output of the scroll signal from the second scroll signal output unit 20 is cut while the detection output of the neutral position marker 41 is supplied from the slide detection sensor 26 to the second scroll signal output unit 20. To be. Therefore, the mouse 1 is configured to display a stable state without shaking or the like on the display screen of the monitor 3.

  In the mouse 1, when the scroll dial 21 is slid leftward from the neutral position, the marker 40 sequentially detects each left individual marker 44 through the left slide marker 42 by the slide detection sensor 26. In the mouse 1, when the scroll dial 21 slides rightward from a predetermined position and returns to the neutral position, the marker 40 is moved from the left individual marker 44 to the neutral position by the slide detection sensor 26. The marker 41 is detected.

  Similarly, when the scroll dial 21 is slid in the right direction from the neutral position, the mouse 40 sequentially detects each right individual marker 45 through the right slide marker 43 by the slide detection sensor 26. In the mouse 1, when the scroll dial 21 slides leftward from a predetermined position and returns to the neutral position, the marker 40 is moved from the right individual marker 44 to the neutral position by the slide detection sensor 26. The marker 41 is detected.

  In the mouse 1, due to the configuration of the marker 40 described above, when the scroll dial 21 is slid to scroll the display screen of the monitor 3 leftward or rightward, the slide detection sensor 26 first sets the left slide marker 42 or After the detection signal of the right slide marker 43 is output, the detection signal of each left individual marker 44 or each right individual marker 45 is output. Further, in the mouse 1, when the scroll dial 21 returns, the detection signal of the left slide marker 42 or the right slide marker 43 from the slide detection sensor 26 is output last.

  In the mouse 1, as described above, the detection signal output from the slide detection sensor 26 is subjected to predetermined signal processing in the second scroll signal output unit 20 to output a left scroll signal or a right scroll signal. The order of the detection signals of the left slide marker 42 and the right slide marker 43 is detected. In the mouse 1, the left scroll signal or the right scroll signal is output only when the detection signals of the left slide marker 42 and the right slide marker 43 are input first.

  It should be noted that the mouse 1 is not limited to the above-described configuration, and it is needless to say that the scroll signal cut processing during the return operation of the scroll dial 21 may be performed by an appropriate configuration and method. In the mouse 1, depending on the user, the scroll signal cut processing may be unnecessary, and for example, it may be possible to cancel at the time of initial setting.

  The mouse 1 is configured to hold the scroll dial 21 in the neutral position so that the base plate 33 of the first bearing portion 30 is held in the neutral position by the pair of tension springs 36A and 36B as described above. Of course, it is not limited to such a holding structure. The mouse 50 shown as the second embodiment in FIG. 6 is characterized in that the scroll dial support shaft 22 is configured to be held in a neutral position by a pair of tension springs 51A and 51B. Since the mouse 50 has the same basic configuration as the mouse 1 described above, the corresponding parts are denoted by the same reference numerals and description thereof is omitted.

  That is, in the mouse 50, as shown in FIG. 6, the tension springs 51A and 51B are provided in a slightly compressed state between the both end portions of the scroll dial spindle 22 and the opposite side portions on the upper half 27 side, respectively. It is done. In the mouse 50, the scroll dial spindle 22 is held in a neutral position by being pressed from both sides by the elastic force of the tension springs 51A and 51B. Therefore, in the mouse 50, the scroll dial 21 fixed to the scroll dial spindle 22 is positioned at the center of the guide opening 29 as shown in FIG.

  In the mouse 50, when the user slides the scroll dial 21 with the fingertip in the guide opening 29, for example, leftward in FIG. 6 from the neutral position, the scroll dial spindle 22 also integrally moves leftward. Move the slide. In the mouse 50, the scroll dial spindle 22 slides while compressing the left tension spring 51A to accumulate a repulsive force and accumulating an elastic force to the right tension spring 51B. In the mouse 50, when the scroll dial spindle 22 slides, the marker 25 is detected by the slide detection sensor 26, and the left scroll signal is output from the second scroll signal output unit 20.

  In the mouse 50, the scroll dial 21 automatically returns to the neutral position when the user releases the fingertip while the scroll dial 21 is slid leftward or rightward. In the mouse 50, the scroll dial support shaft 22 is compressed by the sliding operation of the scroll dial support shaft 22 so that the repulsive force is stored and stretched, and the elastic force of the tension springs 51 </ b> A and 51 </ b> B is stored. The shaft 22 returns from the slide position to the neutral position. In the mouse 50, the scroll dial 21 returns to the neutral position in the guide opening 29 via the scroll dial support shaft 22.
