JPS6243628A - Coupling mechanism between two devices - Google Patents

Abstract

PURPOSE:To couple two devices without any play by simple structure and easily operation by inserting a number to be locked which projects from the coupling surface of the 1st device and has a surface in a reverse cone shape into the coupling hole of the 2nd device, and locking them by a locking member. CONSTITUTION:When coupling rods 108, 110, and 112 of a battery holder B are inserted into three holes 114a-114c of a motor driving device A, the top end of the rod 110 is pressed against a lock lever 118 and a lever tip part 118c disengages from the raised part 116c of a coupling plate 116, which moves to left. Reverse conic parts of lower half parts 108Ab and 110Ab of the rods 110 and 112 are pushed up by the right narrow width part of a hole 116 a and the devices A and B are coupled with each other without any play. The reverse conic surface 112Ab of the rod 112 contacts the end surface of a hole 120a elastically to prevent the rods from coming out. Thus, the two devices are coupled with each other securely by the simple structure.

These conventional rock structures include a locking stage 1 to lock both devices in a coupled state, a lock release operation 11 member operated to release the opening, and a 7° 1 point for both devices to look into the locked stage. There is a separation lever etc. to be operated, and when the two are to be coupled, chucking is performed by aligning the coupling surfaces of the two at ti' and ii and operating the lock release member. Also, to separate both people, if you operate the separation lever while operating the lock release member, the chuck will be released.

The predetermined short time is set to be shorter than the time from the start to the end of one shooting, and only 10 shots are taken while the release prohibition signal is not output. Further, the release prohibition circuit '5 always outputs a release prohibition signal when the switch (512) is opened. In addition, the camera body (C) is a motor drive device Q\)
When the camera is mounted, the photographing operation is started when a winding completion signal is obtained from the winding device provided in the camera body and no release prohibition signal is input from the motor drive device (8). Therefore, the camera body (C) equipped with the motor drive device fAl starts the next shooting operation immediately after the winding is completed in the To mode, and waits for a predetermined period of time after the winding is completed in the L mode. Shooting 1: The same operation is started, and in S mode, the next shooting starts when the release button is released and the release button is pressed 10 times. Figure 3 shows the internal mechanism of the motor drive device (~I). The motor (~I) has a drive shaft (NI2) and (14) on both sides, and the drive shaft (~[2) has a winding The drive shaft (M4) is connected to the hoisting drive mechanism. The gear (G2) fixed to the drive shaft (M2) is connected to the gear (G

and is connected to the planet gear (G12) via a sun gear (Glo) formed integrally with the rough bevel gear (G8). The planetary gear (G12) is a gear (cl.
It is rotatably supported on the F plane of 1), and the cam wheel: 40
It is connected to the internal gear (.10G) formed at j. On the outer periphery of the cam ring (40), there is a fi
A protrusion (40C) is provided. The gear (Gl 6 ) connected to the gear (G14) has a one-way flange (4
21, the drive pin (42Th), and the flange (44a) to the transmission shaft '41). The coupler (2) is supported so as to be able to slide in the axial direction and rotate integrally with the transmission shaft [41], and is biased upward. The lever (46) is supported by the shaft (tH3n) so as to rotate around it, and is biased so as to be in arcuate contact with the outer circumferential wall of the cam ring '40).
The rotation of the protrusion (·loc>) is stopped with a predetermined force. When a predetermined force or more is applied to the cam ring (40) in the counterclockwise direction in the figure, the protrusion (40's tilted surface) pushes away the lever (46), so the cam ring moves in the counterclockwise direction of '40i'. The lever (center) is supported by a shaft (48; In this state, the light end of the lever (center) is pressed against the cam ring (4 (lD protrusion (ll OC)).
When the cam 1:40) rotates counterclockwise in the figure, the lever (40C) is activated by the protrusion (40C).

The tooth 11 (G12) is given a driving force to rotate counterclockwise in the figure. Now, the rotation of the cam ring '4θ) is prevented by the engagement 1 between the protrusion (40C) and the lever (46), so the planetary gear (C12) is rotated by the internal gear (=loG) of the cam ring (40). + gear meshes, rotates clockwise in the figure, and connects via gear (Gl 4 ) (7 gear)

The motor (M) stops between the position where it passes the position where it engages with the lever (48) and the position where it engages with the lever (41F), and then the motor (M) rotates forward and the hoisting V1 is started. Then, the protrusion (・10C) is stopped after turning 1σj until +c is held. In addition, when the motor (M) reverses, the sun gear (GIO)
Since the planetary gear (G12) rotates counterclockwise and the planetary gear (G12) rotates clockwise, the cam ring (40) rotates clockwise and engages with the step of the protrusion (=lOC) or the tip of the lever (48). . This (from this) the rotation of the cam (・裔′・IC) is ejected, so either the a!

The gear (G18) fixed to the drive 1qb (M4) is connected to the worm tooth El (G24) via the gear (C; 20) and the worm (022). The worm tooth 1 (Gz4) is integrally connected to the sun gear (G26) by a shaft supported so as not to change its position.The sun gear (G26) is connected to the planetary gear (G28). The planetary gear (G28) is rotatably supported on the shaft (541) on the lever threshold via a friction coupling mechanism, as shown in Fig. 3. The gear (G30) revolves between a detached position where it comes off from the gear (C; 30) as shown in Figure 4 (al) and a connected position where it meshes with the gear (G30) as shown in Figure 4 (b). gear (G3) connected to the transmission shaft (transmission shaft)

In other words, lever threshold: Even if this clockwise rotational behavior is given, when planet gear α rotates clockwise, planet gear ◎ engages with the tip of the lever (rib) and the lever (

The sliding plate 70) has elongated holes (70a) and (70b) supported by fixing pins (70C) and (70d) so that it can slide in the left and right directions in the figure and is biased left and right in the figure.

In the free state, the urging force causes the engaging part (lsb) to move to the protruding position ([pl [5] or support H't: 92).
If the end is in elastic contact with the end, it will stop, and if you simply push it in, it will come into contact with the step (181) or the support plate, and reach the push-in position. In order to push in the IJ, turn the setting knob (8) clockwise in Fig. 5 against the bias until it comes off the step (18) or support plate (92), and then push it into the push-in position. (Rub.

It has an arm that engages with the pin (9Gb), and is biased in the left and right direction in the figure with a biasing force that is stronger than the specific biasing force and weaker than the biasing force of the lever. There is. The rewind setting button 1 has an operating part (201), and is moved by a mechanism (not shown) to the position where it protrudes from the opening on the rear surface of the motor drive device. The normally open switch (S/l) is supported to move between the rewind setting button 120) and is biased f:1 to the protruding position. 20; Closed by being pressed by 1). The lock plate (102) has an opening (1021) into which the operating portion (20a) can be inserted, is supported to move in the left-right direction, and is urged to the right position.

Since it is located in a position that is covered by the palm of the hand, the photographer does not feel uneasy about the lack of a safety lock device. According to the invention described above, the joining surfaces of the two devices are brought together;
When the locked member is fitted into the coupling hole of the second device, chunking is automatically performed and the two devices are ignited. Also, when separating both and 1, it is only necessary to operate the holding member to move it to the holding position 1◇. As a result, it is possible to remove X1 from fF1'it, and when Shika connects two devices, the two are definitely connected.
