Pulse patterns 48d and 48e are provided respectively.

As shown in FIG. 2, the operation body 31 has a square flat plate portion 51 that slides on the receiving surface 25, and a long hole 41 and a holder of the holding body 23 that protrude from the flat plate portion 51. The projecting portion 52 is inserted into the long hole 44 of the holding body 24, one end of which is a regular square columnar projection 52 exposed from the opening 29 of the upper plate 30, and is formed of an elastic synthetic resin. As shown in FIG. 1, elastic members, for example, elastic tongues 53a to 53d, which push the flat plate portion 51 toward the intermediate portion side from the moving end portion are provided at the respective side ends of the flat plate portion 51, and the elasticity is provided. The tip ends of the tongue pieces 53a to 53d can contact the inner frame 26. Further, two sets of slide contact members, for example, slide contact pins 55a to 55d, which are arranged on the upper surface of the flat plate portion 51 so as to sandwich the first holding body 23 and are in slidable contact with both side surfaces of the holding body 23, respectively. Two holding bodies 24 are arranged so as to be sandwiched, and two sets of sliding contact members, for example, sliding contact pins 54a to 54d, which are in sliding contact with both side surfaces of the holding bodies 24, respectively, are provided.

As shown in FIG. 1, the above-mentioned blind cover plate 32 is formed by a square thin plate member whose one side is slightly longer than the long side of the opening 27, and the projection 52 of the operating body 31 is inserted in the central part. It has a square hole 32a through which it passes. The above-mentioned another blind cover plate 33 is formed of a rectangular thin plate material having a short side slightly longer than one side of the blind cover plate 32 and a long side longer than the short side, and has a central portion of the operating body 31. It has a long hole 33a through which the protrusion 52 is inserted. These blind plates 32 and 33 are sequentially stacked on top of the substrate 28, are movable independently of each other, and cover the opening 29.

In this embodiment, when the cursor displayed on the display device is moved to an arbitrary position, the protrusion 52 is slid with a finger of the hand or the like, and the protrusion 52 is turned upside down to project onto a base (not shown). The first holding body 23 moves relative to the X-direction patterns 47a to 47c of the substrate 28 by contacting the portions 52 and gripping the outer frame 22, and the Y-direction pattern. The second holding body 24 moves relative to 48a to 48c.

At this time, the slider 43a is brought into sliding contact with the pseudo pulse pattern 47d to output a pseudo pulse control signal, and a pseudo endless output is performed. Therefore, the cursor displayed on the display device continues to move. .. Then, when the protrusion 52 is released, the operating body 31 returns to the position shown in FIG. 3B due to the elastic force of the elastic tongue piece 53d, and the slider 43a is separated from the pseudo pulse pattern 47d. The output of the pseudo pulse control signal stops. The same applies when the operating body 31 is moved to the other moving end in the X direction or to the moving end in the Y direction.

In the embodiment configured as described above, the cursor displayed on the display device can be moved in an arbitrary direction according to the relative movement amount of the operating body 31 without requiring a ball, a rotary encoder, or the like.

Further, since the plurality of blind cover plates 32 and 33 that can move independently of each other are provided to block the opening 29 of the upper plate 30, the respective blind cover plates 32 and 33 are set to be relatively small. It is possible to reduce the size of the casing. Further, since the elastic tongues 53a to 53d are integrally formed with the flat plate portion 51 of the operation body 31 as elastic members that push back the holding bodies 23 and 24 from the moving end portions to the central portion side, the number of parts is reduced. Therefore, the cost of parts and the number of assembling steps can be reduced.

Further, in this embodiment, the axial pressing force applied to the protrusion 52 by the pressing operation of the protrusion 52 of the operating body 31 is applied to the receiving surface 25 of the lower plate 21 via the flat plate portion 51. The holders 23 and 24 can be smoothly moved because the axial pressing force is not applied to the holders 23 and 24. Further, in this embodiment, the sliding contact pins 55a to 55d of the flat plate portion 51 sandwich the first holding body 23, and the other sliding contact pins 54a to 54d sandwich the second holding body 24, whereby the holding body is held. The intermediate portions of 23 and 24 can be respectively guided and moved more smoothly, and since the holding bodies 23 and 24 are held in a state of being orthogonal to each other, the detection error is reduced and the detection accuracy is improved. Therefore, it is possible to obtain an XY direction input device having higher resolution.

In this embodiment, both the X-direction pattern and the Y-direction pattern are provided on the substrate 28. However, there are a substrate provided with the X-direction pattern and a substrate provided with the Y-direction pattern. May be divided.

Further, in the present embodiment, of the blind cover plates 32 and 33, the blind cover plate 32 is first arranged on the substrate 28, and another blind cover plate 33 is stacked on the blind cover plate 32.
