Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an information processing apparatus capable of inputting information using a rotating body.

[0002]

2. Description of the Related Art Conventionally, a device using an annular rotating bezel 1 as shown in FIG. 1 has been used as an input device such as a mode switching device and a time correction device for small devices such as wristwatches. These devices switch the mechanical switch by the operation of the rotating bezel 1, and for example,
There is a device in which a pin is passed through the body of a wristwatch and the mode is switched by pressing a circuit spring with the pin.
In this device, the pin is engaged with the back surface of the rotating bezel 1, and the user switches the plurality of circuits by rotating the rotating bezel 1 to move the position of the pin. .

[0003]

However, this is an input device configured to switch the mechanical switch such as a pin or the like by rotating the rotating bezel as described above, and to switch a large number of tens of circuits such as character input. In order to perform this, the structure becomes complicated, and the device becomes large-scale. Therefore, it has not been possible to mount it on a small portable information device such as a wristwatch.

Further, in a device using a mechanical switch mechanism, since a part of the mechanical switch mechanism is exposed to the outside of the wristwatch, there is a problem that waterproofness is impaired. It is necessary to arrange a packing in a gap that is often present in a mechanical mechanism. When many packings are provided in this manner, friction generated between the packing, the rotating bezel, and the body increases, so that a large force is required to rotate the rotating bezel, and operability is deteriorated. Further, if such a device is continuously used, the packing deteriorates, the operability further deteriorates, and the waterproofness may be impaired.

[0005] In order to solve these problems, an information device having a structure without using a mechanical switch having a complicated structure includes an optical pattern formed on the lower surface of a rotating bezel and an optical sensor for detecting the optical pattern. Portable devices are conceivable. In this portable device, the optical sensor detects the optical pattern formed on the lower surface of the rotating bezel, thereby detecting the rotating angle and the rotating direction of the rotating bezel,
The input information is generated from the detection result. As described above, in the device using the optical sensor, since the rotation amount of the rotating bezel is detected in a non-contact manner, the optical sensor can be disposed inside the sealed device, and the waterproofness can be maintained. As well as inputting a lot of information.

By the way, in a portable device using the above-described optical sensor, it is possible to prevent water from entering the inside of the device in which the optical sensor, the electronic circuit and the like are arranged, but it is necessary to provide a clearance between the rotating bezel and the body. If external light enters from above, it is conceivable that an erroneous detection is made by the entered light. If packing is arranged between the rotating bezel and the body in order to prevent such erroneous detection, operability will deteriorate as described above.

[0007] The present invention has been made in view of the above circumstances, and has a configuration that can be easily miniaturized, allows a large amount of information to be input more accurately, and is operable and waterproof. It is an object of the present invention to provide an information processing device having excellent performance.

As shown in the figure, similarly to the pulse number detection sensor unit 32 described above, the click pin 230 is
01 is disposed inside the portion where the guard member 201 is disposed. Here, FIG.
A side sectional view of the vicinity is shown. As shown in the figure, the click pin 230 is disposed in a recess 232 formed in the body 101. The click pin 230 is attached to the spherical upper end 23.
3 and a spring portion 234 for applying a force to push the upper end portion 233 upward. When there is a click groove 235 formed in the rotating bezel 102 above the upper end portion 233, When the protrusion protrudes from the concave portion 232 and enters the click groove 235 and there is no click groove 235,
The depression 2 is pushed down by the back surface of the rotating bezel 102.
32. Thus, even when the rotating bezel 102 is rotated, the specific (click groove 2)
The rotation bezel 102 is positioned at a position (engagement of the click pin 230 with the click pin 230).

FIG. 5 is a view taken along the line V--V in FIG. As shown in the figure, a step is formed on the surface of the rotating bezel 102 so that the outer peripheral side is lower, and information such as characters is displayed on a surface at a higher position on the inner peripheral side.
On the other hand, the rotating bezel 102
The optical pattern 41 is formed at a position corresponding to information such as characters displayed on the surface of the optical pattern 41. A hole 31a is formed below the optical pattern 41 formed on the back surface of the rotating bezel 102, and a sensor cover glass 42 is arranged so as to cover above the hole 31a. A packing (not shown) is disposed between the body 101 and the sensor cover glass 42 to prevent water, dust, and the like from entering below the sensor cover glass 42.

Below the sensor cover glass 42, a pulse number detecting 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. The LED 44 emits light toward the optical pattern 41, and generates a pulse signal based on the amount of reflected light from the optical pattern 41 received by the photodiode 45. . The rotation direction detection sensor unit 33 has the same configuration as the pulse number detection sensor unit 32, and reads the optical pattern 41 formed on the back surface of the rotating bezel 102 to generate a pulse signal.

The substrate 46 of the pulse number detection sensor unit
Is connected to the electronic circuit section of the wristwatch-type information processing apparatus 100 by a lead wire (not shown), and the number of pulses of the pulse signal generated by the pulse number detection sensor unit 32 is output to an information signal generation section described later. You. The number of pulses of the pulse signal is counted by the information signal generation unit, and thereby the rotation angle of the rotating bezel 102 is detected.

A guard member 201 for blocking light is arranged on the side of the outer periphery (left side in the figure) of the rotating bezel 102. The guard member 201 includes a mounting portion 240 that is mounted on the body 101 by screws, and a holding portion 241 that protrudes from the mounting portion 240 toward the rotating bezel 102. The rotating bezel includes the holding portion 241 and the body 101. 102
Part of the outer peripheral side of is sandwiched. Thereby, when the rotating bezel 102 is rotated, the holding portion 241 and the body 1
01, the rotating bezel 102 slides. By sandwiching the rotating bezel 102 in this manner, the rattling of the rotating bezel 102 in the vertical direction can be reduced, and the rotation of the rotating bezel 102 can be stabilized.

Here, a rotating bezel 102 is attached to the body 101.
A step is formed such that a sliding surface 101a between the body and the body 101 is disposed above a screwing surface 101b to which the mounting portion 240 is screwed. By providing such a step, the outer peripheral side of the sliding surface 101a is
1 to prevent external light from entering the pulse number detection sensor unit 32 through a gap between the body 101 and the rotating bezel 102.

Next, the optical pattern 41 formed on the back surface of the rotating bezel 102 will be described with reference to FIG. As shown in the figure, in the optical pattern 41, absorption regions 41a that absorb light emitted by the LEDs 44 and reflection regions 41b that reflect light emitted by the LEDs 44 are alternately formed. At this time, the absorption area 41a and the reflection area 41b are formed at every angle θ _{2 about the} rotation center O. Here, when the number of characters displayed on the rotating bezel 102 is n (n is an even number), θ ₂ = 360 /
n ゜. Under this configuration, when the rotating bezel 102 is rotated, the pulse number detection sensor unit 32 reads the absorption area 41a and the reflection area 41b alternately, thereby generating a pulse signal as shown in FIG. be able to.

Next, the angle θ ₁ between the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 shown in FIG. 3 will be described. In the present embodiment, θ ₁ = mθ
₂ + _{θ 2/2} (m is an integer) so as to pulse count detection sensor unit 32 and the rotational direction detection sensor unit 33
Is arranged. When the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 are arranged as described above, a pulse signal as shown in FIG. 8 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. Therefore,
The rotation direction of the rotating bezel 102 can be detected by detecting such a phase delay / phase advance.

[0025] In addition, θ ₁ of the angle is not limited to _{mθ 2 + θ 2/2,} k * 360 / n (k is an integer of up to 0~n-1) may be a different angle, for example, θ ₁ = Mθ ₂ + θ ₂ /
It may be four. In short, 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.

Returning to FIG. 6, on the outer peripheral side of the optical pattern 41 on the back surface of the rotating bezel 102, each absorption area 4 is provided.
A click groove 235 is formed corresponding to 1a and the reflection area 41b, that is, corresponding to a character or the like displayed on the surface of the rotating bezel 102. Thus, when the rotating bezel 102 is rotated, the above-described click pin 230
And the click groove 235 are sequentially engaged with each other to move one absorption region 41a or reflection region 41b.
That is, each time the rotating bezel 102 is moved by θ ₂ゼ ル, the rotating bezel 102 is positioned.

Next, a functional configuration for generating information such as characters from the rotation angle and rotation direction of the rotating bezel 102 detected as described above and displaying the information on the display device 104 will be described with reference to FIG. In the figure, reference numeral 81 indicates an information signal generation unit which is a signal generation unit. Information signal generator 81
Has a pulse number counter, and includes a pulse number detection sensor unit 32 and a rotation direction detection sensor unit 33.
The information signal is generated based on the rotation angle of the rotating bezel 102 detected by counting the number of pulses of the pulse signal generated by the rotating bezel 102 and the rotation direction of the rotating bezel 102 detected as described above. 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. The character generator 83 displays information such as characters on the display unit 104 based on the information signal generated in this manner.

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 information generated by the information signal generation unit 81, respectively. When the information generated by the information signal generator 81 is a kana character, the voiced dot switch 107 adds a voiced dot. When the information is in English characters, the voiced dot switch 107 switches between lowercase letters and uppercase letters.

The information generated by the information signal generator 81 is not limited to character information, but may be character editing such as line feed, 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
Command information such as character editing and mode switching is stored in correspondence with the rotation angle and rotation direction of the rotating bezel 102, and based on the detected rotation angle and rotation direction of the rotating bezel 102, an information signal generation unit is provided. 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 "K", "K" 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 device 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 In the wristwatch-type information processing apparatus 100 according to the present embodiment, as described above, the rotation angle and the rotation direction of the rotating bezel 102 can be detected in a non-contact manner, and information to be input can be generated based on the detection result. While having a simple configuration, it is possible to input a large amount of information such as information such as characters and mode selection. Further, as described above, since the pulse number detection sensor unit 32, the rotation direction detection sensor unit 33, and the like are arranged in the closed space in the holes 31a and 31b, the waterproofness is excellent.

Further, since a guard member 201 for blocking light is disposed outside a portion where the pulse number detecting sensor unit 32 and the rotation direction detecting sensor unit 33 are disposed, a gap between the rotating bezel 102 and the body 101 is provided. Thus, it is possible to prevent external light from entering the vicinity of the sensor. Therefore, erroneous detection of the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33 is reduced, and more accurate information input can be performed.

As a method of preventing external light from entering the inside of the apparatus as described above, a method of arranging a packing in a gap between the rotating bezel 102 and the body 101 can be considered. In this case,
The friction generated between the packing and the body 101 and the rotating bezel 102 prevents the rotating bezel 102 from rotating smoothly. For this reason, the user applies force to rotate the bezel 10.
2 must be rotated, and the operability deteriorates. In addition, when a device in which the packing is disposed in the gap between the body 101 and the rotating bezel 102 is used, the operability further deteriorates due to the deterioration of the packing rubber. However, in the present embodiment, as described above, the torso 101 and the torso 10
External light can be prevented from entering the vicinity of the sensor without providing a packing in a gap between the sensor and the sensor.

As a method for preventing the invasion of external light, a groove is provided on the body 101 in a circumferential shape, and the rotating bezel 102 is provided.
It is also conceivable to form a ridge that fits into the groove on the back surface of the body.
The size of the torso 101 is increased. However, in the present embodiment, since the gap near the sensor where external light is to be prevented is covered by the guard member 201, it is not necessary to enlarge the body 101 except for the portion where the guard member 201 is disposed. . The guard member 201 is attached to an upper part of the body 101 where the band portion 200 is attached, that is, a member (band holding portion) that projects outward from the rotating bezel 102 even when the guard member 201 is not attached. Since the device is mounted at the position where the device exists, the apparatus does not increase in the planar direction (the direction of the paper surface of FIG. 2).

Further, in the present embodiment, the guard member 20
1 is screwed, so that the guard member 201 is
01 can be easily removed. Further, since the rotating bezel 102 is held by being sandwiched between the guard member 201 and the body 101, the guard member 20
By removing 1, the rotating bezel 102 can be removed, and the work of removing dust between the rotating bezel 102 and the body 101 can be easily performed. In addition, if the information signal generation unit 81 can input information other than the kana characters described above and information different from the information displayed on the rotating bezel 102, for example, English characters by switching the mode, the rotating bezel 102 As shown in FIG. 11, it is necessary to display English characters or the like on the surface of the rotating bezel, that is, it is necessary to replace the rotating bezel with another rotating bezel on which the English characters are displayed. Even in such a case, in the present embodiment, if the guard member 201 is removed, the rotating bezel 102 can be easily replaced.

In this embodiment, the click pin 230 and the click groove 235 are provided on the body 101 and the rotating bezel 102 to improve the operability. Accordingly, when the rotating bezel 102 is rotated, when the portion above the click pin 230 where the click groove 235 does not exist passes, the rotating bezel 102 tends to rise due to the force of the spring portion 234. When the rotating bezel 102 rises in this way, the body 101 and the rotating bezel 10
2 becomes large, and external light easily enters. However, in the present embodiment, since the click pin 230 is disposed inside the guard member 201, the guard member 201
The rotating bezel 102 is pressed downward by the holding portion 241 of the rotary shaft. This makes it possible to prevent the rotating bezel 102 from trying to float, and to reduce the intrusion of external light near the sensor.

Further, the rotating bezel 1 is usually operated by the user.
02 is rotated, the user can rotate the bezel 102
In FIG. 2, the user tries to rotate by holding a part (left and right sides in FIG. 2) that is not pressed by the guard member 201.
Therefore, the rotating bezel 102 located above the portion where the click pin 230 is provided is less likely to be pressed by the user's hand. Click pin 23
When an excessive pressing force is applied from the upper part of the zero, the friction between the click pin 230 and the back surface of the rotating bezel 102 (the portion where the click groove 235 is not formed) increases, and the rotation of the rotating bezel 102 becomes unstable. However, in this embodiment, unnecessary pressing force is hardly applied from above the click pin 230, and the rotating bezel 102
Can be maintained in a stable rotation.

D. Modifications The present invention is not limited to the above-described embodiment, and various modifications as described below are possible.

(1) In the above embodiment, the cylinder 1
Although the guard member 201 is attached to the 01 by screws, the present invention is not limited to this, and the guard member 201 may be attached by another method. For example, the torso 101
The guard member 201 may be attached to the body 101 by forming a recess in the body 101 and fitting the protrusion formed on the guard member 201.

(2) In the above embodiment, the cylinder 1
Although the guard member 201 is attached to the body 01, the body 101 and the guard member 201 may be integrally formed. In this case, as shown in FIG.
2 is a rotating bezel 10 in a concave portion 400 formed in the body 101.
It is sufficient to fit the portion on the outer peripheral side of 2.

(3) In the above-described embodiment, the rotation amount and the rotation direction of the rotary bezel 102 are detected by using the two optical sensors of the pulse number detection sensor unit 32 and the rotation direction detection sensor unit 33. Although the input information is generated based on the detection result of the above, it is also possible to detect only the rotation amount of the rotating bezel 102 with one optical sensor and generate the information signal based on the detection result. For example, rotating bezel 1 in any direction
02, the alphabetical order such as “A, I, C,...” Or “A, B,
The input information may be generated in alphabetical order such as "C,...". In this case, since the input information is generated based only on the rotation amount of the rotating bezel 102 without depending on the rotating direction, input corresponding to the position of a character or the like displayed on the surface of the rotating bezel 102 cannot be performed. As shown in FIG. 7, a rotating bezel 102 with no characters or the like displayed on its surface may be used.

(4) 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. It is suitable for portable information processing devices.
In this case, a disk-shaped rotating body may be used in addition to the rotating bezel.

[0044]

As described above, according to the present invention,
By performing non-contact rotation amount detection using an optical sensor, it is possible to input a large amount of information with a simple configuration that is easy to reduce in size, and to improve waterproofness. In addition, by holding the rotating body by the holding member and preventing external light from entering near the optical sensor, the detection accuracy of the optical sensor can be improved, and more accurate information input can be performed. In addition, there is no need to provide packing or the like for blocking external light, and the rotating operation of the rotating body is simple.
