Description

[Detailed description of the invention] This invention relates to the setting of a device for operating the strobe switch built into the camera.The switch button is made into a knob type, and when the strobe is used, it protrudes above the camera. In recent years, cameras have been designed to be held in the pushed-in position when the strobe is not in use, and to be held in the pushed-in position when the strobe is not in use. An object of the present invention is to provide the above-mentioned knock-type switch button device, which is suitable for assembling an exterior cover not by the conventional top cover (so-called warship) method but also by a method in which the top cover and front cover are integrally molded. It is something.

Conventionally, as shown in Fig. 1, the method of assembling the exterior cover of a camera has generally included a top cover 1 (so-called warship), a front cover 2, a body 3, a bottom cover 4, and a rear cover 5. It was something that would become possible.

In the case of such a type, the switch button 6 could conventionally be assembled by attaching it to the upper cover 1 and covering it with the upper cover 1 from above. However, in recent years, due to design requirements or cost reduction requirements, a method has emerged in which a top cover 1, a front cover 2, and a bottom cover 4 are integrally molded to form an exterior cover 7 as shown in FIG. 2. For this reason, it is no longer possible to put it on from above as in the past, and it has become necessary to fit it in from the front. This made it impossible to incorporate a switch button. Therefore, in the present invention, when assembling the exterior cover, the switch button is pushed in beyond the locus area where the exterior cover is fitted, and after the exterior cover is assembled, the switch button is made to protrude to achieve this purpose. It is related to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments shown in the drawings.

In Figures 3 and below, 3 is the body of the camera, and 7 is an exterior cover in which a front cover and an upper cover are integrally molded. 7' is a switch button seat fixedly attached to the exterior cover 7. 6 is a switch button, and the part protruding from the exterior cover 7 is color-coded for the tip 6' and shaft 6'' for easy identification. (6' and 6'' are two-color molded, etc.) (It is integrally molded.) This switch button 6
has an engaging pin 8 integrally fixed thereto and a rising limit step 9, and is biased upward by a spring 10 (see FIG. 4). A switch device 12 consisting of a plurality of movable contact pieces and a group of fixed contact pieces is attached between the switch button 6 and a switch plate 11 attached to the camera body 3. In this switch device 12, when the switch button 6 protrudes upward (position 6a in the figure), the fixed contact group and the movable contact group come into contact to bring the strobe switch device 12 into a connected state. Therefore, when the switch button 6 is pushed in, as shown by the solid line in the figure, both contact pieces are separated, resulting in a state when the strobe is not used. Reference numeral 13 denotes a locking member, which is attached to the mounting plate 3' of the camera body 3 so as to be rotatable and vertically movable about a shaft 14. That is, the engagement between the spring 15 and the rising portion 16 allows rotation around the shaft 14, and the coil portion of the spring 15
It can be elastically lifted up and down from the mounting plate 3' of the body 3.
This locking member 13 includes a first engaging portion 17 for engaging and holding the aforementioned engaging pin 8, a second engaging portion 19 below the first engaging portion 17, that is, on the shaft hole 18 side of the locking member 13; It has a communication groove 25 that communicates the first and second engaging parts 17 and 19, and is located at the upper end of this groove 25, with the lower part rising in the opposite direction to the shaft part 6'' side of the switch button 6. It has a diagonal rising portion 20 for engaging and disengaging the first engaging portion 17, a guide cam surface 21 for guiding the first engaging portion 17, and a cam surface 22 for regulating the amount by which the engaging pin 8 is pushed down (Fig. 5). 23 is a rotation stopper for this member 13.

When assembling the exterior cover 7 into the body 3 now, attach the shaft 14 to the mounting plate 3' of the body 3, and
The shaft hole 18 of the locking member 13 is loosely fitted into the locking member 13, and the spring 15 is pressed in the upward and downward direction, and the tip of the spring 15 is engaged with the rising portion 16 to urge it to rotate counterclockwise in FIG. The switch button 6 is inserted into the through hole 24 of the body 3, and the engagement pin 8 is inserted into the second engagement portion 19.
to engage. Then the head of switch button 6 is 6b
Since the exterior cover 7 is held in the position shown by , the exterior cover 7 can be easily assembled to the body 3 from the front.

After this assembly, insert something like a screwdriver into the hole in the button seat 7' and push the head of the switch button 6 slightly, and the engagement pin 8 will descend from the second engagement part 19 and be removed from the engagement part 19. At the same time, the member 13 is rotated counterclockwise by the bias of the spring 15 and stopped at the stopper 23. At this time, the engagement pin 8 is located within the communication groove 25 that communicates both the first and second engagement portions 17 and 19, and is located below the diagonally rising portion 20. Therefore, when the pressure on the head of the switch button 6 is released and the button 6 is made to protrude from the button seat 7' by the accumulated force of the spring 10, the engagement pin 8 rises within the communication groove 25 and the diagonally rising portion 20
The locking member 1 enters the lower slope (in Fig. 3) of
3 comes out of the guide cam surface 21 while being separated from the mounting plate 3' in the vertical direction. Then, the locking member 13 is brought into close contact with the mounting plate 3' again by the pressure of the coil portion of the spring 15. When the presser on the switch button 6 is released, the limiting step 9 of the switch button 6 is pressed against the lower surface of the button seat 7' by the accumulated force of the spring 10, and the head of the switch button 6 is at the position 6a. That is, the switch device 12 is kept in the ON state, and the head of the switch button 6 protrudes beyond the camera, indicating that the strobe can be used, and the assembly is completed.

Next, to release the strobe device so that it is not used, press down the switch button 6 with your finger, as shown in FIGS. 3 and 4. The amount of pushing at this time is such that the upper surface of the switch button 6 is pushed in slightly more than the upper surface of the switch button seat 7' since it is pressed by a human finger. At this time, the engagement pin 8 comes into contact with the guide cam surface 21 of the locking member 13,
When the member 10 descends while being pushed away clockwise and reaches a position where it is removed from the guide cam surface 21, the member 10 rotates counterclockwise by the rotational force of the spring 15 and engages the engaging pin 8 and the side surface of the diagonally rising portion 20. It touches and stops. Therefore, when the finger is released from the switch button 6, the engagement pin 8 is engaged and held by the first engagement portion 17.
However, in order to use the flash from the lever position, when the tip of the switch button is at the 6' position,
When this is further pressed so that the top surface of the tip portion 6' is approximately the same level as the top surface of the button seat 7', the engagement pin 8 is guided by the regulating cam surface 22 or by the diagonally rising portion 2.
0, the member 13 rotates counterclockwise and stops at the rotation stopper 23. Then, when the pressure on the switch button 6 is released, the engagement pin 8 enters the lower surface of the diagonally rising portion 16, and when it is pulled up and moves away from the guide cam surface 21, the tip of the switch button 6 moves to the point 6a. The switch device 12 is brought into the ON state by protruding into the position.

It goes without saying that the device of the present invention can also be used in conventional methods of dividing exterior covers. As described above, the device of the present invention can be easily and easily assembled regardless of how the exterior cover is divided.
