DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a wireless input type information processing apparatus (notebook personal computer) according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a wireless input type notebook personal computer.

In FIG. 1, A is a main body with a display unit in which a liquid crystal display unit 2 is assembled to the main body 1. The display unit 2 is attached to the main body 1 so as to be tiltable and undulating.

Reference numeral 4 denotes a wireless input device formed separately from the main body A with a display unit, and 5 a transmission unit provided in the wireless input device 4. The transmission unit 5 is used for input operation in the wireless input device 4. It is designed to send an infrared wireless input signal with a code corresponding to.

Reference numeral 100 denotes a receiving section provided in the cabinet of the display section 2 in the main body A with a display section. The receiving section 100 has a direction in which its receiving field of view is variable relative to the display section 2. It is configured as a variable receiver.

2A and 2B show a detailed sectional structure of the variable direction receiver 100. FIG. 2A is a plan sectional view, FIG. 2B is a front sectional view, and FIG. 2C is a side sectional view.

In FIG. 3, 11 is a cabinet of the display unit 2, 12 is a hemispherical concave portion integrally formed in the cabinet 11, and 13 is a hemispherical vertical rotation fitted in the hemispherical concave portion 12. Reference numeral 14 denotes a spherical left-right rotating portion fitted in the hemispherical vertical rotating portion 13.

The hemispherical up-and-down rotating portion 13 is integrally formed with up-and-down rotating shafts 13a at both left and right ends thereof, and is supported on the up-and-down rotating shaft 13a in a hemispherical recess 12 so as to be rotatable around a horizontal axis. There is. In addition, the hemispherical vertical rotation unit 13
A slide protrusion 13b is integrally formed in the central portion of the back surface of the, while a vertical guide groove 12a for slidably guiding the slide protrusion 13b is provided on the inner surface on the inner side of the hemispherical recess 12. Has been formed.

The left and right rotating shafts 14a are integrally formed at the upper and lower ends of the spherical left and right rotating portion 14 so as to project integrally, and the left and right rotating shafts 14a are rotatably supported by the hemispherical up and down rotating portion 13 about the vertical axis. There is. In addition, the spherical left-right rotating unit 14
A slide protrusion 14b is integrally formed in the central portion of the back surface of the, while a lateral guide groove 13c for slidably guiding the slide protrusion 14b is fitted on the inner surface of the back side of the hemispherical vertical rotating portion 13. Are formed.

A printed circuit board 15 and a light receiving element 16 such as an infrared phototransistor mounted on the printed circuit board 15 are disposed inside the spherical right and left rotating portion 14. An optical filter 17 is attached to the center of the front surface of the spherical left-right rotating unit 14. The light receiving element 16 is arranged immediately after the optical filter 17. A harness 19 is led out from the printed board 15 via a connector 18. The harness 19 is guided from the shaft hole of the left and right rotating shaft 14a to the inside of the hemispherical up-and-down rotating portion 13, and further to the main body 1 side through the shaft hole of the up-and-down rotating shaft 13a and the hemispherical recess 12.

As in the case of the conventional example, when an input operation is performed on the wireless input device 4, an infrared wireless input signal having a code corresponding to the input operation is radiated into space from the transmitter 5. When the infrared wireless input signal reaches the variable direction receiver 100 of the display-equipped main body A, the optical filter 17 removes the noise component, and then the light-receiving element 16 receives the noise component, and the main body is passed through the connector 18 and the harness 19. It is guided to the first side, decoded in the main body 1, and then transmitted to the CPU.

Next, the operation of the direction variable receiver 100 configured as described above will be described.

First, FIGS. 3 (a) and 3 (b) show how the receiving field of view is swung in the left-right direction.

When the spherical left / right rotating portion 14 is manually pushed to the left from the home position shown in FIG. 2, the spherical left / right rotating portion 14 is pressed.
Rotates leftward (clockwise) around the left-right rotation shaft 14a with respect to the hemispherical vertical rotation unit 13. During this rotation,
The slide protrusion 14b of the spherical left-right rotating unit 14 is guided by the lateral guide groove 13c of the hemispherical vertical rotating unit 13.
Rotation of the spherical right-and-left rotating portion 14 to the left is performed by the slide protrusion 1
It is possible until 4b is received by the right end of the lateral guide groove 13c. The maximum rotation angle from the home position to the left side is about 60 °, and the state when rotated leftward to the maximum rotation angle is shown in FIG.

The spherical left / right rotating unit 14 is on the right side (counterclockwise direction).
The same applies to the operation when rotating the disk at a maximum rotation angle of about 60 °. The state when rotated rightward to the maximum rotation angle is shown in FIG. The slide protrusion 14b is received by the left end of the lateral guide groove 13c.

The hemispherical vertical rotating unit 13 does not rotate when the spherical horizontal rotating unit 14 is rotated only around the horizontal rotating shaft 14a as described above.

Next, FIGS. 4 (a) and 4 (b) show how the receiving field of view is swung up and down.

When the spherical left / right rotating unit 14 is pushed upward from the home position in FIG. 2, the rotational force applied to the spherical left / right rotating unit 14 is applied to the hemispherical vertical rotating unit 13 via the left / right rotating shaft 14a.
Therefore, the spherical left / right rotating unit 14 and the hemispherical vertical rotating unit 13 are integrally rotated with respect to the hemispherical recess 12 about the vertical rotating shaft 13a. During this rotation, the slide protrusion 13b of the hemispherical up-and-down rotating unit 13 is guided by the vertical guide groove 12a of the hemispherical recess 12. The upward rotation of the hemispherical vertical rotation unit 13 is possible until the slide protrusion 13b is received by the lower end of the vertical guide groove 12a. The maximum rotation angle from the home position to the upper side is also about 60 °, and the state when the upper rotation is performed up to the maximum rotation angle is shown in FIG.

The operation when rotating downward is the same, and the maximum rotation angle at this time is about 60 °. The state when rotated downward to the maximum rotation angle is shown in FIG.
Is shown in. The slide protrusion 13b is the vertical guide groove 12.
It is received by the upper end of a.

Spherical left / right rotating unit 14 and hemispherical up / down rotating unit 1
Since 3 and 3 are configured like a universal joint (cross joint), the spherical left-right rotating portion 14 can be rotated in any direction. That is, the horizontal rotation of the spherical left-right rotating portion 14 with respect to the hemispherical vertical rotating portion 13 around the horizontal rotating shaft 14a, and the hemispherical recess 1 around the vertical rotating shaft 13a.
This is a combined movement of the vertical rotation of the hemispherical vertical rotation unit 13 with respect to 2.

Since the horizontal rotation and the vertical rotation are caused at the same time, the spherical horizontal rotating portion 14 can be smoothly rotated in an arbitrary direction.

The printed circuit board 15, the light receiving element 16 and the optical filter 17 also rotate integrally with the rotation of the spherical left / right rotating unit 14. Therefore, the variable direction receiving unit 100 can be used without moving the display-equipped main body A itself.
The direction of the receiving field of view of the (light receiving element 16 and the optical filter 17) can be varied vertically and horizontally in a stereoscopically wide range. The variable range of the receiving field of view is about 12 in the left-right direction.
The angle is 0 °, and it is about 120 ° in the vertical direction, which is a greatly enlarged size as compared with the conventional example.

Further, since the rotation angle is limited within a certain range (both about 120 °) both in the horizontal direction and in the vertical direction, there is no possibility that the harness 19 is accidentally broken due to kinking.

The present invention is not limited to the structure of the variable direction receiving unit 100 in the above embodiment, but may be any one having the same function. The location of the variable direction receiver 100 need not be limited to the cabinet 11 of the display unit 2, and may be attached to the cabinet of the main body 1. The wireless input device 4 may be a pen input type or a keyboard type. The information processing device to be applied may be a laptop personal computer, a desktop or laptop personal computer, or a word processor.

[0035]

As described above, according to the present invention, the wireless input signal receiving unit is configured as a direction-variable type receiving unit in which the direction of the receiving field of view is variable relative to the main body with the display unit. Therefore, when the transmitting unit is out of the receiving field of view of the receiving unit on the main body side with the display unit when the position of the wireless input device is changed, in adjusting the transmitting unit to be in the receiving field of view, Unlike the conventional example, it is not necessary to adjust the entire orientation of the main unit with a display unit, and it is possible to easily deal with it by adjusting the orientation of only the variable direction type reception unit, and the good operability that the wireless input method aims at is achieved. It can be fully used as it should be.
