【Example】

 In the three embodiments described below, the shooting lens is automatically brought to the in-focus state by the operation of the automatic focusing device to perform shooting, and when the automatic focusing operation is inappropriate, the manual operation is performed as necessary. This is an example of a range finder AF camera capable of focusing.

First, a first embodiment will be described with reference to FIGS. The camera body 1 is provided with a window 2 in which a range finder and a so-called distance measuring device for measuring a distance to an object are stored. The taking lens 3 is extended by pressing down the release button 4, and the amount of extension is limited by the output of the distance measuring device. In this way, the in-focus state is automatically obtained and shooting is performed. The above-described distance measuring device and the means for limiting the amount of extension of the taking lens 3 by the output of this distance measuring device are the automatic focus adjusting devices, but since this mechanism is well known, its explanation is omitted.

On the upper surface of the camera body 1, two operation members, that is, a knob 5 for turning on a power source and a focusing switching dial 6 are rotatably provided. The knob 5 is rotated by operating a knob 7 provided integrally with the knob 5 to turn on power to electric circuits such as an automatic focus adjustment device and an automatic exposure control device. The dial 6 is rotated by operating the knob on its outer circumference to enable or disable the automatic focusing device. When the automatic focus adjusting device is inoperable, the taking lens 3 can be extended to a position corresponding to the rotating position of the dial 6, and a manual focusing operation can be performed. . A mechanism for driving the taking lens 3 by an automatic focus adjusting device or for switching it to a manually set position is publicly known, and a description thereof will be omitted.

The structures of the knob 5, the dial 6 and the vicinity thereof will be described in detail below. In this embodiment, raised portions 1b and 1c are formed between the knob 5 and the dial 6 and outside the dial 6 so that the camera body upper surface 1a is partially raised. The raised portions 1b and 1c, the knob 5 and the dial 6 are respectively formed with linear patterns 1d, 1e, 1f, 5a and 6a. These patterns are all formed in the same color, and different colors are selected from the camera upper surfaces 1a, 1b, 1c, the knob 5, the dial 6, and the knob 7 that surround the pattern. Then, as shown in FIG. 2, when the pattern 5a of the knob 5 is matched with the pattern 1d on the raised portion 1b, the power supply to all the electric circuits of the camera including the automatic focusing device and the automatic exposure control device is cut off. Be struck

As shown in FIG. 3, when the knob 5 is rotated to match the index 5b with the pattern 1d, electric power is supplied to electric circuits such as an automatic focusing device and an automatic exposure control device. When the index 5c is matched with the pattern 1d, power is supplied to the self-timer circuit in addition to the automatic focus adjustment device and the automatic exposure control device. That is, when the index 5c matches the pattern 1d, the self-timer shooting is selected.

Further, when the index 6b provided on the pattern 6a of the dial 6 is aligned with the index 1g provided on the pattern 1e as shown in FIG. 2, the automatic focus adjusting device becomes operable. Of course, at this time, if the pattern 5a of the knob 5 matches the pattern 1d, even if the release button 4 is pressed, the automatic focus adjustment device, the automatic exposure control device, etc. do not operate, and the photographing is not performed. .

When the index 6c is matched with the index 1g, the automatic focusing device becomes inoperable. Therefore, at this time, even if the indexes 5b and 5c of the knob 5 match the pattern 1d, the automatic focusing device does not operate. That is, the automatic focus adjusting device operates in conjunction with the pressing of the release button 4 only when the indicators 5b and 5c of the knob 5 match the pattern 1d and the index 6b of the dial 6 matches the index 1g. It is a thing. Then, when the index 6c matches the index 1g, the taking lens 3 comes to focus on an object 1m in length like a character engraved on the dial 6.

The taking lens 3 may be extended so as to focus on a 1 m subject at the same time as the rotation of the dial 6, or may be extended so as to focus on a 1 m subject only when the release button 4 is pressed. . If the index 6d or 6e is matched with the index 1g, the photographic lens 3 remains inoperable in the same manner as described above, and the photographic lens 3 is matched to the object of 2m or 3m as the characters engraved on the dial 6. I will get impatient. FIG. 3 shows a state in which the index 6d matches the index 1g. In this way, manual distance setting is performed.

Further, in the present embodiment, the pattern 1f is provided at a position facing the pattern 1e with the dial 6 interposed therebetween, and the index 1h is provided on the pattern 1f. The indexes 6f, 6g, 6h, 6i on the dial 6 respectively match the index 1h when the indexes 6b, 6c, 6d, 6e match the index 1e. The indexes 6f, 6g, 6h, and 6i indicate AF, 3.3ft, 6.6ft, and 9.9ft, respectively, like the characters engraved on the dial 6. Therefore, in the present embodiment, it is possible to set the manual distance by the metric method by matching the indexes 6b to 6e with the index 1e, and by setting the index 6f to 6i with the index 1h, the manual distance setting by the foot method. You can also do it.

In a camera capable of automatic focus adjustment, automatic focus adjustment is normally used, and the power source of the camera is normally turned off in a state where no image is taken. In the camera of this embodiment, as shown in FIGS. 1 and 2, automatic focus adjustment is selected, and when the power is turned off, the respective linear patterns 1f, 6a, 1e, 1d, 5a are aligned in a straight line. It is very easy to identify that a given state is in place. Therefore, it is possible to easily prevent forgetting to turn off the power when the camera is left for a long time, and forgetting to select the auto focus adjustment when taking out the camera to start shooting.

Further, in the embodiment, in the state of FIG. 2, the contour lines of the raised portions 1b and 1c and the contour line of the knob 7 also extend along the patterns 1f, 6a, 1e, 1d and 5a. It becomes easier to identify that the member is in the predetermined state. Next, a second embodiment will be described with reference to FIGS. In the first embodiment, linear patterns 1f, 6a, 1e, 1d, and 5a, which are unified in the same color, are provided on the two operation members 5 and 6 and the camera body 1, respectively. When it became, the linear patterns were arranged in a straight line. In the second embodiment described below, the contour line of the raised portion formed on the upper surface of the camera body 1 and the contour line of each operation member themselves form a linear pattern. This is different from the first embodiment in that the outlines of the members are arranged in a straight line.

As shown in FIG. 4, on the upper surface 1a of the camera body 1, raised portions 17, 11b and 11c are formed by partially raising the upper surface 1a. The power-on knob 15 is rotatably provided between the raised portions 17 and 11b, and the focusing switching knob 16 is rotatably provided between the raised portions 11b and 11c. Then, as shown in FIG. 5, when the index 15a on the knob 15 is raised 11, more specifically, when it is matched with the character OFF engraved on the raised portion 11b, power supply to all electric circuits is cut off.

As shown in FIG. 6, when the index 15a is matched with the index 11i on the body 1, power is supplied to the automatic focus adjustment device, the automatic exposure control device, and the like. When the index 15a is matched with the index 11j on the body 1, power is supplied to the self-timer circuit as well as the automatic focus adjustment device and the automatic exposure control device. Further, as shown in FIG. 5, when the index 16a on the knob 16 is matched with the raised portion 11c, more specifically, the character AF engraved on the raised portion 11c, the automatic focus adjusting device becomes operable. When the index 16a matches the indices 11k, 11l, 11n, respectively, the taking lens 3 comes to focus on the subjects 1m, 2m, 3m. FIG. 6 shows a state where an object of 2 m is in focus. The power supply to the automatic focus adjustment device, the automatic exposure control device, the self-timer circuit, etc., the operation of the automatic focus adjustment device, the manual distance setting, etc. are achieved in the same manner as in the first embodiment.

In this embodiment, the camera body upper surface 1a, the raised portions, and the knobs are all of the same color except for the index and the character. In the present embodiment, the raised portions 17, 11b, 11e and the knobs 15, 16 described above, more specifically, the outlines 17a, 15b, 11p, 16b, 11q thereof form linear patterns, respectively. As shown in FIG. 5, when the automatic focus adjustment is selected and the power is turned off, the raised portions 17, 11b and 11c and the knobs 15 and 16, more specifically, the outlines 17a, 15b, 11p, 16b and 11q of the raised portions 17a, 15b, 11p, 16b and 11q are set to one. Align in a straight line. Then, as clearly shown in FIG. 4, it is as if one raised portion is formed by the raised portions 17, 11b and 11c and the knobs 15 and 16. Therefore, as in the first embodiment, it is possible to very easily identify that the operating member is in the predetermined state, and it is possible to easily prevent forgetting to turn off the power or forgetting to select the automatic focus adjustment. .

FIG. 7 shows a third embodiment which is a modification of the second embodiment. In this modification, the patterns 11e ', 16', 11b ', 15' and 17 '(corresponding to 11c, 16, 11b, 15 and 17 of FIG. 5, respectively) are formed in a curved shape with some curvature as shown. Has been done. Then, when the operating member is brought into a predetermined state, each pattern is provided so as to form one large continuous curved pattern having some curvature. Others are the same as those in the first embodiment. According to the present invention, each pattern 11c ', 16', 11b ', 15', 17 'having a certain curvature may be used to form one large continuous curved pattern having a certain curvature. .

Although the above-described three embodiments have been described using the focusing switching operation member and the power-on operation member, the present invention has an operation member for turning on the power of the built-in strobe and a rewinding operation. It can also be applied to an operation member for carrying out the operation, an operation member for imprinting data, and the like. That is, when the power of the strobe is turned off, when the rewinding state is released, and when data is imprinted for each shot of one frame, the pattern formed on each operation member is linear or You may comprise so that it may be arranged in a curvilinear form.
