2. Description of the Related Art Conventionally, a device using a rotating bezel 1 as shown in FIG. 1 has been used as an input device such as a mode switching device for a small device such as a wristwatch or a time correction device.

FIG. 3 shows a wristwatch type information processing apparatus 10.
0 shows a state in which the rotating bezel 102 has been removed. As shown in the figure, holes 31a and 31b are formed in the body 101, and a pulse number detection sensor unit 32 and a rotation direction detection sensor unit 33 are disposed in the holes 31a and 31b, respectively. Here, the pulse number detection is performed so that the line connecting the pulse number detection sensor unit 32 and the rotation center O of the rotating bezel 102 and the line connecting the rotation direction detection sensor unit 33 and the rotation center O form an angle θ _1. Sensor unit 32 and rotation direction detection sensor unit 3
3 are arranged respectively. In addition, the pulse number detection sensor unit 32 is disposed below (in the back side of the paper of FIG. 2) below the character or the like (“A” in FIG. 2) indicated by the above-described instruction mark 110. It will be described later angle theta _1.

FIG. 4 is a view taken along the line IV-IV in FIG. As shown in the figure, an optical pattern 41 is formed on the lower surface of the rotating bezel 102 at a position corresponding to a character or the like formed on the upper surface of the rotating bezel 102. A sensor cover glass (light transmitting member) 42 is attached to the body 101 below the surface on which the optical pattern 41 is formed. At this time, the body 101 and the sensor cover glass 4
A packing 43 is provided between the two, so that water or the like can be prevented from entering the lower portion of the sensor cover glass 42. The sensor cover glass 42 will be described later.

Below the sensor cover glass 42, a pulse number detection sensor unit 32 is provided. The pulse number detection sensor unit 32 includes an LED (Light Emitting
Diode) 44, photodiode 45, and LED 44
Light-blocking plate 44 disposed between
a, and a substrate 46, wherein the LED 44 emits light toward the optical pattern 41 disposed thereon, the reflected light is received by the photodiode 45, and a pulse is generated based on the received optical pattern 41. A signal is generated. Thus, the pulse number detection sensor unit 3
The number of pulses of the pulse signal 2 generated is counted by an information signal generation unit 81 (see FIG. 10) described later, and the rotation angle of the rotating bezel 102 is detected. The rotation direction detection sensor unit 33 has the same configuration as the pulse number detection sensor unit 32, and the optical pattern 4
1 is read to generate a pulse signal.

The substrate 4 of the pulse number detection sensor unit 32
A contact spring 47 is provided below 6, and the contact number spring 47 electrically connects the pulse number detection sensor unit 32 and the CPU of the wristwatch-type information processing apparatus 100. Note that a lead wire may be provided instead of the contact spring 47.

As shown in FIGS. 3 and 4, a groove 34 is formed in the upper part of the body 101 on the circumference. On the other hand, as shown in FIG. 4, on the lower surface of the rotating bezel 102, a ridge 46 projecting downward is formed.
4 is slidably fitted. For this reason, it is possible to prevent external light from entering the vicinity of the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33, thereby reducing the occurrence of malfunctions in the respective detections.

An O-ring 47 is disposed between the right side of the rotating bezel 102 in the figure and the body 101.
This prevents water, light, and the like from entering the inside of the wristwatch-type information processing apparatus 100.

Next, the optical pattern 41 will be described. FIG. 5 is a diagram illustrating the lower surface of the rotating bezel 102. As shown in the figure, the optical pattern 41 has a low reflection area 41a and a high reflection area 41b of the light irradiated by the LED 44, and the low reflection area 41a and the high reflection area along the rotation circumference of the rotating bezel 102. The reflection areas 41b are alternately arranged.

FIG. 6 is a view taken along the line VI-VI of FIG. As shown in FIG.
It has a concave portion 102a and a convex portion 102b alternately formed along the rotation circumference, and the low reflective region 41a is arranged in the concave portion 102a, and the high reflective region 4 is formed in the convex portion 102b.
1b is provided. Thereby, the distance between the pulse number detection sensor unit 32 and the low reflection area 41a is large,
Also, the high reflection area 41b and the pulse number detection sensor unit 3
2 is made smaller. As described above, since the low-reflection region 41a is provided in the concave portion 102a, the low-reflection region 41a is hardly stained or scratched, and has excellent wear resistance. Furthermore, by reducing the distance between the pulse number detection sensor unit 32 and the high reflection area 41b, it is possible to reduce dust and the like from entering between them.

As the low reflection area 41a as described above,
For example, a black sheet is used. On the other hand, as the high reflection area 41b, for example, a metal material such as aluminum can be used. Also, by using aluminum or the like having a large thickness as the high reflection region 41b, the high reflection region 41b is formed.
Can be prevented from lowering the reflectance with respect to abrasion. By making the surface roughness of the concave portion 102a larger than that of the convex portion 102b, the low reflection area 41a is formed in the concave portion 102a.
02b may be provided with a high reflection area 41b.

Returning to FIG. 5, the low reflection area 41a and the high reflection area 41b are formed at every angle θ _{2 about the} rotation center O. That is, the above-mentioned concave portion 102a and convex portion 102b are also formed for each angle θ ₂ . Here, characters and the like formed on the upper surface of the rotating bezel 102 are n
In the case of the number (n is an even number), θ ₂ = 360 / n ゜. When the user rotates the rotating bezel 102, the pulse number detection sensor unit 32 alternately reads the low reflection area 41a and the high reflection area 41b, thereby obtaining the signal shown in FIG.
Can be generated. By detecting the number of pulses, the rotation angle of the rotating bezel 102 can be detected. Note that the rotation direction detection sensor unit 33 similarly generates a pulse signal.

As shown in FIG. 6, the sensor cover glass 42 is composed of a glass 50 as a light transmitting body and a light shielding sheet 51 for absorbing light.
Are alternately arranged in the left-right direction in the figure, which is a direction perpendicular to the detection direction. An anti-reflection film 53 is deposited on the upper and lower surfaces of the sensor cover glass 42, thereby reducing the reflectance of the sensor cover glass 42. As such an antireflection film 53,
For example, cryolite or magnesium fluoride is used.
In addition, as the light shielding sheet 51, a light reflector can be used. Further, both a light shielding sheet made of a light reflector and a light shielding sheet made of a light absorber may be used.

Next, the angle θ ₁ between the pulse number detecting sensor unit 32 and the rotation direction detecting sensor unit 33 will be described. In this _{embodiment, θ 1 = θ 2 + θ} 2/4 become as pulse count detection sensor unit 32 and the rotational direction detection sensor unit 33 is disposed. Accordingly, when the rotating bezel 102 is rotated by the user, the pulse signal generated by the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 is 3 /
A phase difference of 8 will occur.

As shown in FIG. 8, when the rotating bezel 102 is rotated clockwise, the pulse signal generated by the rotation direction detecting sensor unit 33 is 3/3 of the pulse signal generated by the pulse number detecting sensor unit 32. When the phase advance of 8 occurs and the rotating bezel 102 is rotated counterclockwise, the pulse signal generated by the rotation direction detection sensor unit 33 is 3/8 of the pulse signal generated by the pulse number detection sensor unit 32. A phase delay will occur.
By detecting such a phase delay / phase advance, the rotation direction of the rotating bezel 102 can be detected.

[0028] In addition, θ ₁ of the value of _{θ 2 + θ 2/4 =} 360 /
Not only n + 90 / n, but k * 360 / n (K is 0 to n−
(An integer up to 1). For example, θ
₁ = in the case of arranging the pulse speed sensor unit 32 and the rotational direction detection sensor unit 33 to θ ₂ + θ _2/2 a position, the pulse signal as shown in FIG. 9 is generated. As shown in the drawing, when the rotating bezel 102 is rotated clockwise, the rotation direction detecting sensor unit 33 is rotated.
Pulse number sensor unit 3
2 leads to a 1/4 phase advance from the pulse signal generated,
When the rotating bezel 102 is rotated counterclockwise,
The pulse signal generated by the rotation direction detection sensor unit 33 has a phase delay of 1/4 of the pulse signal generated by the pulse number detection sensor unit 32. As described above, θ ₁ may be any angle that causes a phase difference between the pulse signals generated by the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33.

Next, a functional configuration for generating an information signal such as a character from the rotation angle and rotation direction of the rotating bezel 102 detected as described above and displaying the information signal on the display unit 104 will be described with reference to FIG. In the figure, reference numeral 81 indicates an information signal generation unit. The information signal generation unit 81 has a pulse number counter, and the pulse number detection sensor unit 32
And an information signal based on the rotation angle of the rotation bezel 102 detected by counting the number of pulses of the pulse signal generated by the rotation direction detection sensor unit 33 and the rotation direction of the rotation bezel 102 detected as described above. To generate. At this time, the information signal generation unit 81
Generates an information signal by referring to an information table 82 in which information signals corresponding to the rotation angle and the rotation direction of the rotating bezel 102 are stored. Based on the information signal generated in this way, the character generator 83
Displays information such as characters on the display unit 104.

The origin switch 108 is used to switch the wristwatch-type information processing apparatus 100 to an information input state.
Is reset to 0, and the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 start detecting the rotation angle and rotation direction of the rotating bezel 102. Confirm switch 105,
The delete switch 106 is used to determine and delete the input information generated by the information signal generation unit 81, respectively. When the input information generated by the information signal generator 81 is a kana character, the voiced dot switch 107 adds a voiced dot. When the input information is English characters, the voiced dot switch 107 switches between lower case and upper case.

The input information generated by the information signal generating section 81 is not limited to characters, but may be character editing such as line feed, or mode switching (for example, switching between a time display mode and a character input mode) in the information processing apparatus. Can also be generated. In this case, the information table 82
Stores command information such as character editing and mode switching corresponding to the rotation angle and the rotation direction of the rotating bezel 102, and based on the detected rotation angle and the rotating direction of the rotating bezel 102, an information signal generation unit. 81 generates command information.

B. Information input method and operation of wristwatch-type information processing apparatus Next, an information input method and operation of the wristwatch-type information processing apparatus 100 will be described. First, the user adjusts the rotating bezel 102 to a predetermined origin position. In the present embodiment, the origin position is set to the state shown in FIG. 2, that is, the state where “A” is indicated by the instruction mark 110. In this state, the user presses the origin switch 108, whereby the wristwatch-type information processing apparatus 100 enters an information input state, and the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 rotate the rotation angle and rotation direction of the rotating bezel 102. Start detection.

When the user wants to input information to be input, for example, the character "f", the "f" formed on the rotating bezel 102 is indicated by the instruction mark 110 as shown in FIG. Rotate the rotating bezel counterclockwise to the right position. At this time, the pulse number detection sensor unit 32 detects the rotation angle θ of the rotating bezel 102, and the rotation direction detection sensor unit 33 detects the rotation direction of the rotating bezel 102. Based on the rotation angle and the rotation direction detected in this way, the input information “f” is output to the information signal generation unit 8.
1 and displayed on the display unit 104. When the confirm switch 105 is pressed in this state, the character "f" is decided, and a state of waiting for input of the next information is entered. When the delete switch 106 is pressed, the character "" is deleted, and the input wait state is entered. Also, when the cloud spot switch 107 is pressed,
“Ga” is displayed on the display unit 104.

C. Effect The information processing apparatus according to the present invention has a simple configuration and can be easily miniaturized even when a large number of information such as character input can be input. Therefore, it is possible to use a wristwatch type as described above.

The wristwatch type information processing apparatus 100
Has a feature in the structure of the sensor cover glass 42, thereby improving the detection accuracy of the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33, thereby enabling more accurate information input. I have.
This will be described with reference to FIGS.

FIG. 12 is a diagram showing a state at the time of detection by the pulse number detection sensor unit 32 or the rotation direction detection sensor unit 33 in the information processing apparatus provided with the sensor cover glass 55 composed of only ordinary glass. . As shown in the figure, the light emitted from the LED 44 travels in the direction indicated by the arrow in the figure. The optical pattern 41 to be detected among these lights (here, the low reflection area 41)
The light traveling toward (a) is absorbed by the low reflection area 41a, while the light traveling obliquely is reflected by other components, for example, the high reflection area adjacent to the low reflection area 41a to be detected. It will proceed toward the area 41b.
Such light is reflected by the high reflection area 41b or the like, and the reflected light may be received by the photodiode 45. That is, even when the low reflection area 41a is detected, a certain amount of light is received by the photodiode 45, and the light reception amount of the photodiode 45 when the low reflection area 41a and the high reflection area 41b are detected. Contrast is reduced. As described above, when the contrast of the amount of light received by the photodiode 45 decreases, the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 may not generate an accurate pulse signal. The rotation angle and rotation direction of 102 cannot be accurately detected.

On the other hand, as shown in FIG. 13, in the wristwatch-type information processing apparatus 100 according to the present embodiment, the sensor cover glass 42 has a structure in which the glass 50 and the light shielding sheet 51 are alternately arranged. The light emitted obliquely in the detection light emitted by the LED 44 is absorbed by the light shielding sheet 51. That is, it is possible to absorb light other than light traveling toward the low reflection area 41a to be detected. Therefore, it is possible to suppress a decrease in the contrast of the amount of light received by the photodiode 45 when the low reflection area 41a and the high reflection area 41b are detected. Detection can be reduced.

Further, the light-shielding sheet 51 regulates the path of light entering from the outside of the apparatus, thereby suppressing the entry of external light below the sensor cover glass 42. Therefore, the detection accuracy of the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 is further improved.

Further, the reflectance of the sensor cover glass 42 is reduced by depositing an anti-reflection film 53 on the upper and lower surfaces of the sensor cover glass 42. By reducing the reflectivity of the upper and lower surfaces of the sensor cover glass 42 in this manner, when detecting the low reflection area 41a, the light emitted from the LED 44 emits light from the sensor cover glass 4
2 can be reduced, and the amount of light that is reflected by the photodiode 45 and received by the photodiode 45 can be reduced. Further, when detecting the high reflection area 41b, it is possible to suppress a decrease in the amount of light received by the photodiode 45 due to, for example, reflection of light from the high reflection area 41b on the upper surface of the sensor cover glass 42. . Therefore, the low reflection area 41a
The contrast of the amount of light received by the photodiode 45 when detecting the high-reflection region 41b and the high-reflection region 41b is improved, and the detection accuracy of the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 can be improved.

Further, this wristwatch type information processing apparatus 100
Are the low reflection area 41a, the pulse number detection sensor unit 32, and the rotation direction detection sensor unit 3 as described above.
3, and the distance between the high reflection area 41b and the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 is reduced (see FIG. 6). Thus, the amount of light received by the photodiode 45 when detecting the low reflection area 41a is smaller, and the amount of light received by the photodiode 45 when detecting the high reflection area 41b is larger. Therefore, the photodiode 45 when detecting the low reflection area 41a and the high reflection area 41b is detected.
, The detection accuracy of the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 can be improved.

D. Modified Example In the above-described embodiment, the sensor cover glass 42 is provided with the glass 50 in a substantially circumferential direction of the rotating bezel 102.
And the light-shielding sheet 51 are arranged alternately. However, the present invention is not limited to this, and the glass 50 and the light-shielding sheet 51 are arranged in a direction perpendicular to the detection direction of the pulse number detection sensor unit 32 or the rotation direction detection sensor unit 33. May be provided as long as they are alternately arranged. For example, as shown in FIG. 14, the pulse number detection sensor unit 32 or the rotation direction detection sensor unit
In the direction of the line connecting the rotation center O (see FIG. 3)
0 and the light shielding sheet 51 may be arranged alternately.

As another modified example, as shown in FIG. 15, the LED 44 and the photodiode 45 in the pulse number detection sensor unit 32 or the rotation direction detection sensor unit 33 are substantially in the circumferential direction of the rotating bezel 102. They may be arranged side by side in the left-right direction.

In the modified examples shown in FIGS. 14 and 15, of the light emitted from the LED 44, the light obliquely traveling toward a portion other than the optical pattern 41 (the low-reflection region 41a in FIG. 15) to be detected. It is possible to reduce the possibility that the light reflected by the upper surface of the sensor cover glass 42 and the reflected light (shown by a broken line in FIG. 15) is received by the photodiode 45. Therefore, it is possible to suppress a decrease in the contrast of the amount of light received by the photodiode 45 when the low reflection area 41a and the high reflection area 41b are detected.

Further, the present invention is not limited to the wristwatch-type information processing apparatus as described above, but can be applied to other types of information processing apparatuses such as mobile phones. in this case,
As a rotating body, a disk-shaped thing may be used other than a rotating bezel.

[0045]

As described above, according to the present invention,
Since the detection accuracy of the optical sensor can be improved while having a configuration that is easy to make small and thin, a large amount of information can be input more accurately.
