Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for mounting an operation button of a camera having a plurality of contacts such as a mode change switch of the camera.
[0002]
[Prior art]
In a camera equipped with a liquid crystal display panel, the user selects a mode while viewing the liquid crystal display panel. In the case of such a camera, the user first operates the operation buttons to sequentially display various modes on the display panel, selects a necessary mode, and presses the determination button to determine the mode.
[0003]
Conventional camera mode selection / determination operation means is a dial-type operation means or a push-type operation button integrated with mode selection / determination.
[0004]
However, in the case of a camera that selects and displays various modes in a matrix on a relatively large display panel, the dial-type operating means must display the mode only by rotating operation, so that it takes time to operate. Moreover, since the mode buttons must be operated at a position away from the dial type operation means, there is a drawback that the usability is poor.
[0005]
In addition, the push-type operation button that integrates mode selection / determination takes time to operate and has the disadvantages of erroneous selection and determination.
[0006]
Japanese Patent Application Laid-Open No. 10-90769 discloses a mode selection button mounting structure. However, the mounting structure of the mode selection button disclosed in Japanese Patent Laid-Open No. 10-90769 is provided with the mode selection button mounting portion because the contact simultaneous pressing prevention portion, the coil spring, the coil spring fixing portion, and the like are arranged on the back side of the mode selection button. There was a disadvantage that became thicker.
[0007]

The contact is formed on the flexible printed circuit board 82 shown in FIG. 6, and the contact is brought into conduction when the contact members 64, 66, 68, 70 and 72 are pressed as described above. Each contact is connected to the LCD display window 38 shown in FIG. 3 via a CPU (not shown), and displays a flash, a self-timer, a focus, a date, and the like on the LCD display window 38 by being conducted.
[0017]
As shown in FIG. 8, three bosses 94, 94, 94 are formed on the outer periphery of the mode determination button 42, and a groove 98 into which the bosses 94, 94, 94 are fitted is formed on the inner peripheral edge 96 of the mode selection button 40. 98, 98 are formed. The boss 94 of the mode determination button 42 is prevented from rotating with respect to the mode selection button 40 by being fitted in the groove 98 of the mode selection button 40. Further, as shown in FIG. The boss 94 is in a positional relationship where it interferes with the inner peripheral edge 96 of the mode selection button 40, and the mode determination button 42 is prevented from coming off from the mode selection button 40.
[0018]
An example of the assembly procedure of the mode selection button 40, the mode determination button 42, the rubber pedestal 60, and the click plate 62 is as follows. (1) First, the contact pressing part 84 of the mode determination button 42 is inserted into the rectangular hole 100 formed in the central part of the rubber base 60. (2) Next, the four contact pressing portions 86 to 92 of the mode selection button 40 are inserted into the four round holes 102, 102, 102, 102 formed in the rubber pedestal 60. Out of the four contact pressing parts 86 to 92, the contact pressing parts 86 and 88 are formed with retaining protrusions 86A and 88A to prevent the rubber pedestal 60 from coming off. When the contact pressing portions 86 to 92 of the mode selection button 40 are inserted into the round holes 102 of the rubber pedestal 60, the boss 94 of the mode determination button 42 is fitted into the groove 98 of the mode selection button 40 as described above. (3) Next, an assembly in which the rubber base 60, the mode selection button 40, and the mode determination button 42 are assembled as described above is inserted into the circular opening 51A from the inner surface side of the back cover 51 shown in FIG. At this time, the pin 51B of the back cover 51 is fitted into the hole 104 of the rubber pedestal 60, and further, the rubber pedestal 60 has a recess 61 and a flat part 63 so as to correspond to the shape of the counterbore 53 of the back cover 51. The rubber base 60 is positioned with respect to the back cover 51. (4) Next, the flexible printed circuit board 82 to which the click plate 62 is bonded is attached to the back cover 51. Finally, the metal pressing plate 106 is fastened to the back cover 51 by screws or the like, and the assembly is attached to the back cover 51. And assemble as shown in FIG. At this time, a flange 51C is formed at the periphery of the circular opening 51A of the back cover 51, and the flange 40A formed on the outer periphery of the mode selection button 40 is in contact with the flange 51C. The above assembly is unlocked.
[0019]
As shown in FIG. 6, the rubber pedestal 60 is formed with a bulging portion 60A at the center, and the bulging portion 60A functions as a return spring, and when the mode determination button 42 is pushed down, Return to the position. Further, the rubber pedestal 60 is formed with a ring-shaped bulging portion 60B around the bulging portion 60A. The bulging portion 60B of the rubber pedestal 60 supports the mode selection button 40 as shown in FIG. 6 and biases upward in FIG. Accordingly, the flange 40A of the mode selection button 40 is pressed against the flange 51A of the back cover 51. In this state, when any one of the marks 74 to 80 of the mode selection button 40 is pressed down, the contact is conducted, and when the pressing force is released, the mode selection button is pressed by the elastic force of the bulging portion 60B of the rubber pedestal 60. 40 returns to the original position.
[0020]
In the above-described embodiment, the operation buttons are attached according to the procedures (1) to (4). However, the present invention is not limited to this, and the procedures may be appropriately replaced.
[0021]
In the above-described embodiment, the bosses 94, 94, 94 of the mode determination button (second switch button) 42 are inserted into and engaged with the grooves 98, 98, 98 of the mode selection button (first switch button) 40. The mode determination button 42 is prevented from rotating and coming off, and the mode determination button 42 moves in the groove (holding means) 98 only in the operation direction. In this case, the boss 94 of the mode determination button 42 is engaged and held in the groove 98 of the mode selection button 40, and there is no need to hold the arm out of the exterior part such as the back cover 51. Miniaturization and thinning can be achieved.
[0022]
In the above embodiment, as shown in FIG. 6, the entire click plate 62 is covered by the rubber pedestal 60, and static electricity does not affect the click plate 62 from the outside of the camera, so that it is possible to prevent camera malfunction and failure.
[0023]
In the above-described embodiment, the contact pressing part penetrates the rubber pedestal 60 and presses the contact member. However, a recess is formed in the part of the rubber pedestal 60 corresponding to the contact pressing part, and the contact member is pressed through the recess. Also good.
[0024]
Further, instead of the rubber pedestal 60 and the click plate 62, a plastic printed material such as PET may be used instead, and a mode selection button and a mode determination button may be attached thereto.
[0025]
【The invention's effect】
As described above, according to the operation button mounting structure of the camera according to the present invention, the elastic material mat is disposed between the operation button and the contact point, so that it is possible to reduce the thickness, and even for a thin exterior part. Can be installed.
