【Example】

 Hereinafter, the adjusting dial of the present invention will be described in detail with reference to the preferred embodiments shown in the accompanying drawings. In this embodiment, a case where the adjustment dial of the present invention is applied to a camera will be described as a representative.

FIG. 1 is a plan view showing a configuration example of a camera having an adjustment dial of the present invention. As shown in FIGS. 1 and 5, a camera 1 includes a camera body 2, an adjustment dial 3 of the present invention, a release switch 5, a liquid crystal display unit 6, a control unit 7, and a main switch 8. The shutter driving unit 9, the diaphragm driving unit 10, the photometric unit 11, the distance measuring unit 12, and the film feeding unit 13 are provided. A lens (not shown) is mounted on the front side (lower side in FIG. 1) of the camera body 2.

The adjustment dial 3 is a means for selecting a desired setting item from a plurality of setting items and adjusting the selected setting item, and is installed at the upper left end of the camera body 2 in FIG. Has been done.

The adjustment dial 3 of this embodiment has four types of shutter speed (Tv value), aperture value (Av value), drive (single image shooting, continuous shooting, self-timer shooting, etc.) of the camera 1 and exposure correction. It is configured so that the setting value of the setting item can be adjusted. The adjustment dial 3 will be described below.

As shown in FIG. 1, the adjustment dial 3 has a dial body 31, an F sensor 41 and an R sensor 43 that are position detecting means, a code plate (not shown), and a conductive brush. . In this case, the rotation amount detecting means 30 is constituted by the code plate and the brush.

The dial main body 31 is rotatably installed with respect to the camera main body 2. As will be described later, the dial main body 31 is rotated in a predetermined direction to adjust set values of setting items.

The code plate is concentrically installed on the back side of the dial body 31 (inside the camera 1) so that the code plate can rotate together with the dial body 31. A predetermined conductor (conductive) pattern (not shown) is formed on the back surface of the code plate so that a signal (information) corresponding to the amount of rotation of the dial body 31 can be input to the control means 7. . That is, on the back surface of the code plate, two identical conductor patterns are arranged with a predetermined gap.

In addition, the brush is arranged such that one end thereof is connected to a circuit formed on a printed circuit board (not shown) and the other end thereof can contact a back surface (a surface on which a conductor pattern is formed) of the code plate. ing. The "rotation amount" of the dial main body 31 is not an absolute value of the rotation amount but a concept including the rotation direction and the amount thereof. That is, it includes a positive value, a negative value, and the amount thereof, such as "-3, -2, -1, 0, +1, +2, +3".

The F sensor 41 and the R sensor 43 are touch sensors, respectively, and are arranged around the dial body 31 so as to face each other with the dial body 31 interposed therebetween. In this case, the F sensor 41 is arranged on the front side of the camera body 2, and the R sensor 43 is arranged on the rear side of the camera body 2 (upper side in FIG. 2). Since the F sensor 41 and the R sensor 43 have the same configuration, the F sensor 41 will be representatively described.

FIG. 2 is a plan view showing a configuration example of the F sensor 41 of the adjustment dial 3. As shown in the figure, the F sensor 41 has a pair of conductive members 411 and 412, one conductive member 411 is grounded to the camera body 2, and the other conductive member 412 is electrically connected to the control means 7. They are connected together.

The pair of conductive members 411 and 412 are joined to the insulating members 413 and 414, respectively, at both ends thereof in a non-contact state with each other. Further, each of the conductive members 411 and 412 is formed such that a central portion (a portion indicated by hatching in FIG. 2) protrudes from the end portion toward the front surface side. In this case, when the conductive members 411 and 412 are brought into contact with each other, the conductive members 411 and 412 are brought into conduction and a weak current flows, which is detected. Hereinafter, the case where the conductive members 411 and 412 are brought into contact with each other to make the conductive members 411 and 412 conductive is referred to as “F sensor 41 is on”, and the case where the conductive members 411 and 412 are not conductive is referred to as “F sensor 41 is off”.

The F sensor 41 as described above is arranged so that only the central portion thereof is exposed to the outside of the camera body 2, and is attached to the camera body 2 by the insulating members 413 and 414 by a fastener (not shown). The reason for arranging the F sensor 41 and the R sensor 43 at the above positions is as follows.

3 and 4 are a perspective view showing a state where the adjustment dial 3 is operated with the thumb and a perspective view showing a state where the adjustment dial 3 is operated with the index finger, respectively. As shown in FIG. 3, when the dial main body 31 of the adjustment dial 3 is operated with the thumb, the dial main body 31 is usually operated from the rear side (left side in FIG. 3) of the camera main body 2, and as shown in FIG. When the main body 31 is operated with the index finger, it is usually operated from the front side (right side in FIG. 4) of the camera main body 2, so that the positions of the F sensor 41 and the R sensor 43 are different from each other during operation. This is to correspond to the positions of the index finger and thumb.

In the case of adjusting the set value by using the adjustment dial 3 as described above, the photographer selects the setting items by selecting the position of the finger to be operated, and rotates the dial main body 31. Adjust the setting value.

Next, the operation of such an adjustment dial 3 will be described. As shown in FIG. 3, when the thumb is operated from the back side of the camera body 2 with the adjusting dial 3 and the finger touches only the R sensor 43, only the R sensor 43 is turned on. Further, as shown in FIG. 4, when the adjustment dial 3 is operated from the front side of the camera body 2 with the index finger and the finger touches only the F sensor 41, only the F sensor 41 is turned on.

Although not shown, when the finger contacts the F sensor 41 and the R sensor 43, the F sensor 41 and the R sensor 43 are turned on respectively, and the finger does not contact the F sensor 41 and the R sensor 43, respectively. , The F sensor 41 and the R sensor 43 are off.

FIG. 5 is a block diagram showing a configuration example of the camera 1. As shown in the figure, the signals (information) from the F sensor 41 and the R sensor 43 are input to the control means 7, respectively.

When the dial body 31 of the adjusting dial 3 is rotated, the code plate is also rotated together with it, whereby the rotation amount detecting means 30 detects the rotation direction from the conduction timing of the conductor pattern and corresponds to the rotation amount. Then, a signal for increasing or decreasing the set value of the setting item is input to the control means 7.

Specifically, as shown in FIG. 5, when the dial main body 31 is rotated in the predetermined direction by one step, the rotation amount detecting means 30 instructs the control means 7 to increase the set value by one step ( Hereinafter, when a dial-up signal is input and the dial body 31 is rotated in the opposite direction by one step, a signal for reducing the set value by one step from the rotation amount detection means 30 to the control means 7 (hereinafter, data A down signal) is input. In this way, a predetermined number of data up signals or data down signals are input from the rotation amount detection means 30 to the control means 7 according to the rotation amount of the dial body 31, that is, the number of steps and the rotation direction.

The control means 7 is usually composed of a microcomputer, and updates setting items and setting values based on each signal input from the adjusting dial 3 and each of the other signals, and a memory (not shown). Remember. The operation of the control means 7 based on each signal input from the adjustment dial 3 will be described later in detail.

Further, the control means 7 outputs an operation signal in accordance with the above setting and adjustment to the shutter drive means 9, the diaphragm drive means 10, the photometry means 11, the distance measurement means 12 and the film feeding means 13 Each of these means is driven according to a predetermined setting. In addition, the control unit 7 also controls various functions of the camera 1 such as sequence control, execution of autofocus, and exposure calculation as necessary.

The main switch 8 is a switch for selecting ON / OFF of the power of the camera 1. When a signal indicating that the main switch 8 is turned on is input to the control means 7, the control means 7 controls so that the functions of the respective parts of the camera 1 are operable. The photometric means 11 measures the brightness of the subject by the light receiving element, and the obtained information (photometric information) is input to the control means 7.

The distance measuring unit 12 measures the distance information from the camera 1 to the object or the defocus amount with respect to the reference focus position (focus position) in the camera 1 by, for example, the active method or the passive method, and is obtained. The information (distance measurement information) is input to the control means 7. The film feeding unit 13 is a unit that winds the film by one frame after photographing.

The release switch 5 is composed of a two-step switch. When the first step of the release switch 5 is turned on, the photometry means 11 and the distance measuring means 12 respectively operate, and when the second step is turned on, the diaphragm drive means. The diaphragm is operated by 10 and the shutter is operated by the shutter driving means 9 to take an image.

In this case, for example, when the shooting mode of the camera 1 is set to “manual”, shooting is performed at the shutter speed and aperture value adjusted by the adjustment dial 3.

Further, when the shooting mode setting of the camera 1 is “aperture priority” and “shutter speed priority”, the control means 7 is based on the photometric information from the photometric means 11 in order to obtain an appropriate exposure amount. The exposure calculation is performed in the calculation unit of, and the shutter speed is determined in the case of "aperture priority", and the aperture value is determined in the case of "shutter speed priority".

That is, in the case of “aperture priority”, shooting is performed with the aperture value adjusted by the adjustment dial 3 and the shutter speed determined above, and in the case of “shutter speed priority”, adjustment is performed. Shooting is performed with the shutter speed adjusted by the dial 3 and the determined aperture value.

The display unit 6 is usually composed of a liquid crystal display panel (LCD) or the like. The display unit 6 displays the contents set and adjusted by the adjustment dial 3 and the like and other items (for example, date and time) according to the output signal from the control unit 7.

FIGS. 6 and 7 are flow charts showing the operation of the control means 7 at the time of shooting. Note that FIG. 6 is a main program, and FIG. 7 is a subroutine program corresponding to step 101 in the main program shown in FIG. The respective flowcharts will be described below.

As shown in FIG. 6, in the main program, first, the setting information set by the operation of the adjustment dial 3 or the like, that is, the shooting mode, the exposure correction, the shutter speed, the aperture value, the drive and the like are input. The set value input process is executed (step 101).

FIG. 7 is a diagram showing the details of the setting value input processing. In this subroutine program, it is judged whether or not the data up signal is inputted from the rotation amount detecting means 30 of the adjusting dial 3 (step 201), when it is determined in step 201 that the data up signal is input, it is determined whether or not the F sensor 41 is turned on (step 202).

When it is determined in step 202 that the F sensor 41 is on, it is determined whether the R sensor 43 is on (step 203), and in step 203, the R sensor 43 is turned on. If it is determined that the value is set, the setting value of "exposure correction" is increased by one step (step 204). That is, when both the F sensor 41 and the R sensor 43 are turned on, the exposure correction can be performed by the adjustment dial 3.

When it is determined in step 203 that the R sensor 43 is off, the setting value of “shutter speed (Tv value)” is increased by one step (step 205). When it is determined that the F sensor 41 is off in step 202, it is determined whether the R sensor 43 is on (step 206), and the R sensor 43 is turned on in step 206. If it is determined that the aperture value is set, the setting value of "aperture value (Av value)" is increased by one step (step 207).

If it is determined in step 206 that the R sensor 43 is off, the “drive” setting value is increased by one step (step 208). That is, when both the F sensor 41 and the R sensor 43 are off, the drive mode can be set by the adjustment dial 3. In the case of a drive, for example, the case where adjustment is made in the order of “single shot” → “continuous shooting” → “self-timer shooting” is called setting value up, and the case of adjustment in the reverse order is set value. It's down.

Next, it is determined whether or not a data down signal is input from the rotation amount detecting means 30 of the adjustment dial 3 (step 209), and when it is determined in step 209 that a data down signal is input, It is determined whether the F sensor 41 is on (step 210).

When it is determined in step 210 that the F sensor 41 is on, it is determined whether the R sensor 43 is on (step 211), and in step 211, the R sensor 43 is turned on. If it is determined that the value is set, the setting value of "exposure correction" is decreased by one step (step 212).

When it is determined in step 211 that the R sensor 43 is off, the setting value of “shutter speed (Tv value)” is decreased by one step (step 213). When it is determined in step 210 that the F sensor 41 is off, it is determined whether the R sensor 43 is on (step 214), and in step 214, the R sensor 43 is turned on. If it is determined that the aperture value is set, the setting value of the “aperture value (Av value)” is decreased by one step (step 215).

When it is determined in step 214 that the R sensor 43 is off, the setting value of “drive” is decreased by one step (step 216). This completes this subroutine program and returns to the main program. Each time the data up signal or the data down signal is input, the set value is incremented or decremented by one step.

As shown in FIG. 6, each set value adjusted by the adjustment dial 3 or the like is input (step 101), and thereafter, it is determined whether or not the first stage of the release switch 5 is turned on (step 101). Step 102). When it is determined in step 102 that the first step of the release switch 5 is turned on, the photometric means 11 and the distance measuring means 12 are activated and the photometric information and the distance measuring information are input respectively (step 103).

Next, based on the photometric information from the photometric means 11, an arithmetic operation of the control means 7 performs exposure calculation, and based on the distance measurement information from the distance measuring means 12, a focusing operation of a photographing lens (not shown). Is performed (step 104).

Next, it is determined whether or not the second step of the release switch 5 is turned on (step 105), and if it is determined in step 105 that the second step of the release switch 5 is turned on, a predetermined value is determined. Shooting is performed in the shooting mode (step 106).

That is, when the shooting mode of the camera 1 is set to “manual”, shooting is performed at the shutter speed and aperture value adjusted by the adjustment dial 3. Further, in the case of “aperture priority”, the aperture value adjusted by the adjustment dial 3 and the shutter speed determined by the exposure calculation, and in the case of “shutter speed priority”, it is adjusted by the adjustment dial 3. Shooting is performed with the shutter speed and the aperture value determined by the exposure calculation. When the shooting is completed, the film feeding means 13 winds the film by one frame (step 107). This is the end of this program.

As described above, according to the adjustment dial 3 of the present embodiment, there is an advantage that the setting item can be selected and the setting value of the setting item can be adjusted by one operation. This simplifies the operation for adjusting the set value and enables quicker adjustment of the set value, as compared with the related art.

Further, since a button-type or dial-type switch for selecting setting items is not required, the installation space can be reduced, the space can be effectively used, the device can be downsized, and the cost can be reduced. It has an advantage that it can be reduced.

Next, another configuration example of the adjusting dial of the present invention will be described. In the following, in each of the embodiments, the main differences from the adjustment dial 3 described above will be described. FIG. 8 is a plan view showing another configuration example of the adjusting dial of the present invention. As shown in the figure, the adjustment dial 3a is obtained by changing the F sensor 41 and the R sensor 43 of the adjustment dial 3 described above from a touch sensor to a photo reflector (optical sensor), and a photo reflector which is a position detecting means. 45 and 46.

The photo reflectors 45 and 46 are arranged around the dial body 31 so as to face each other with the dial body 31 interposed therebetween. Since the photo reflectors 45 and 46 have the same configuration, the photo reflector 45 will be representatively described.

FIG. 9 is a sectional view taken along the line AA in FIG. As shown in the figure, the photoreflector 45 includes a casing 451, and a light projecting unit 452 and a light receiving unit 453 installed in the casing 451. In this case, on the surface side of the casing 451, a member made of a material is used so that the irradiation light from the light projecting means 452 (for example, infrared light) is not reflected by the casing 451 itself to turn on the photo reflector 45. ing.

As shown in FIG. 8, the photo reflector 45 having such a configuration is fixed to the photo reflector fixing member 47, and only the photo reflector 45 is arranged so as to be exposed to the outside of the camera body 2. The photo reflector fixing member 47 is attached to the camera body 2 by a tool.

Next, the operation of the photo reflector 45 of the adjustment dial 3a will be described. As shown in FIG. 9, infrared light is emitted from the light projecting means 452 of the photo reflector 45, and when the finger 14 is brought into contact with or brought close to the photo reflector 45, the infrared light is reflected by the finger 14. Then, the light receiving means 453 is irradiated, and the photo reflector 45 is turned on.

Further, when the finger 14 is not brought into contact with or brought close to the photo reflector 45, the photo reflector 45 is off. The signals (information) from the photo reflectors 45 and 46 are respectively input to the control means 7 and used in the same manner as in the case of the adjustment dial 3.

Next, another configuration example of the adjusting dial of the present invention will be described. FIG. 10 is a plan view showing another configuration example of the adjusting dial of the present invention. As shown in the figure, the adjusting dial 3b includes a dial body 31, a first gear 151 which is a first driven rotating member, a first code plate 161, a brush 171, and a second driven member. It has a second gear 152 that is a rotating member, a second code plate 162, a brush 172, a third gear 153 that is a driving rotating member, and a support member 18.

In this case, the displacement direction detecting means for detecting the displacement direction of the dial main body 31 includes the first gear 151, the second gear 152, the third gear 153, the first code plate 161, and the second cord. It is composed of a plate 162, a brush 171, and a brush 172. The displacement direction detecting means also serves as the rotation amount detecting means.

The support member 18 of the adjustment dial 3b is installed rotatably around the pin 181 with respect to the camera body 2 at one end side thereof, and the rotating shaft 33 of the dial body 31 at the other end side thereof. I support you. In this case, the camera body 2 is formed with an elongated hole 191 extending in the moving direction of the rotating shaft 33 so that the rotating shaft 33 can move when the supporting member 18 rotates about the pin 181. .

The third gear 153 is joined to the rotary shaft 33 of the dial body 31 on the back surface side of the dial body 31. In this case, the third gear 153 selectively meshes with the first gear 151 or the second gear 152, which is arranged to face the third gear 153, by the movement of the dial body 31. Is configured to be able to.

Further, the first gear 151 and the first cord plate 161 are coaxially formed so as to be able to rotate integrally, and similarly, the second gear 152 and the second cord 152 are formed. The plate 162 is also coaxially formed so that it can rotate integrally.

Further, one end of the brush 171 is connected to a circuit formed on a printed circuit board (not shown), and the other end is in contact with the surface of the first code plate 161 (the surface on which the conductor pattern is formed). It is arranged. Similarly, one end of the brush 172 may be connected to a circuit formed on a printed circuit board (not shown) and the other end may contact the surface of the second code plate 162 (the surface on which the conductor pattern is formed). It is located in.

The first code plate 161 and the brush 171 constitute a first rotation amount detection means, which also serves as a sensor for detecting the rotation of the first gear 151. Also, the second code plate 162 and the brush 172 constitute a second rotation amount detecting means, which also serves as a sensor for detecting the rotation of the second gear 152.

Next, the operation of the adjusting dial 3b having such a configuration will be described. As shown in FIG. 10, when the dial main body 31 of the adjustment dial 3b is pressed toward the first gear 151 side, the support member 18 rotates about the pin 181 in the clockwise direction in FIG. The third gear 153 moves, and the first gear 151 and the third gear 153 mesh with each other.

In this state, when the dial body 31 is rotated, the third gear 153 integrated with the dial body 31 is rotated. Then, the rotation of the third gear 153 causes the first gear 151 meshing with the third gear 153 to rotate, and the first code plate 161 integrated with the first gear 151 also rotates. As a result, a data up signal or a data down signal is input to the control means 7 from the first rotation amount detection means.

When the dial main body 31 is pressed in the opposite direction to the above, the support member 18 rotates in the opposite direction to the above with the pin 181 as the center, whereby the third gear 153 moves and the second gear 153 moves. The gear 152 and the third gear 153 mesh with each other.

In this state, when the dial main body 31 is rotated, the third gear 153 integrated with the dial main body 31 is rotated. Then, similarly to the above, the rotation of the third gear 153 causes the second gear 152 meshing therewith to rotate, and the second code plate 162 integrated with the second gear 152 rotates. To do. As a result, the data up signal or the data down signal is input to the control means 7 from the second rotation amount detection means.

In this case, the signal from the first rotation amount detecting means is adjusted to the set value of, for example, “shutter speed (T v value)”, and the signal from the second rotation amount detecting means is changed to, for example, “aperture value ( Av value) ”is used to adjust the set value.

As described above, in the adjustment dial 3b of the present embodiment, by pressing the dial body 31 in the predetermined direction to move the dial body 31, one of the two setting items is selected, By rotating the dial main body 31, the set value is adjusted.

Next, another configuration example of the adjusting dial of the present invention will be described. 11, 12 and 13 are respectively a front view showing another configuration example of the adjusting dial of the present invention, a sectional view taken along the line BB in FIG. 11, and a line taken along the line CC in FIG. It is a sectional view. Note that the switch mechanism, the brush, and the like are omitted in FIG. 11.

As shown in FIGS. 11 and 12, the adjustment dial 3c includes a dial main body 31, a first switch means 231, a second switch means 232, a code plate 163 as a rotation amount detecting means, and a brush. It has 173 and the support member 22.

A long hole 193 is formed in the upper plate 201 of the camera body 2. The direction of the long hole 193 coincides with the moving direction of the rotary shaft 34 of the dial body 31 described later. A vertical plate 202 is formed on the camera body 2 in a direction perpendicular to the upper plate 201.

The support member 22 is composed of a flat plate 221 and a projecting portion 222 formed at one end of the flat plate 221 so as to project vertically to the flat plate 221. The support member 22 is rotatably installed on the vertical plate 202 of the camera body 2 around the pin 183 at the projecting portion 222.
