Below, with reference to Fig. 9 (A)～(D) and above-mentioned Fig. 5,7,8 etc., the switch motion of the over cap 5 on the camera 1 of the present embodiment with said structure is described.
Fig. 9 (A)～(D) represents that respectively over cap is under the switch motion state; the bonding state of the over cap back side and protecgulum; and the section configuration of the C1 among Fig. 5, C2, C3, C4, C5 along the Y direction; state during Fig. 9 (A) expression over cap P1 in the closed position; state when Fig. 9 (B) expression over cap is in half-open position P2; state when Fig. 9 (C) expression over cap is in accurate open position P3, the state when Fig. 9 (D) expression over cap is shown in an open position P4.
At first, when over cap 5 was in off-position P1 shown in Figure 5, yes is in retracted position in the indentation camera body for lens barrel 6.Over cap 5 in this state, shown in Fig. 9 (A), ball 11,12 embeds among recess 5f1, the 5f2, remains on the above-mentioned off-position P1 by means of predetermined clamping force.In addition; be in the over cap 5 of this off-position, because the front end crimping face 5i of its fore-end rear side can be crimped on the crimping face 2d of opening portion 2a side of protecgulum 2, so; even to-Z direction pressurization, it can not be out of shape yet to the fore-end of over cap 5.Also have; under the closed condition of over cap 5; because under the state that convex bound fraction 5e is not in not with the bossing 2e of protecgulum 2 combines; so; when the guiding protuberance 5b, the 5c that make over cap 5 with brute force are shifted with respect to protecgulum 2; just can disassemble the over cap made from synthetic resin 5, perhaps, can install.
Secondly, when operation protection lid 5, it is slided, when reaching half-open position P2, to-directions X just shown in Fig. 5, Fig. 9 (B), opened the part of lens barrel 6 fronts.In addition, the convex bound fraction 5e of over cap 5 enters the back side one side of the bossing 2e of protecgulum 2, is in bonding state.Under this bonding state, the sliding contact surface 5e1 of the front of the over cap 5 on the convex bound fraction 5e (camera surface one side) and protecgulum 2 interior surface opposing one side, just can with the bossing 2e sliding contact of protecgulum 2.Therefore, the part relative with the bossing 2e of over cap just remains on not under the state with respect to the place ahead (+Z direction) displacement of protecgulum 2.That is, be bearing in and do not produce under the state that rocks.
Then, when over cap 5 continues to slide to-directions X, when reaching accurate open position P3, just shown in Fig. 5, Fig. 9 (C), the front of lens barrel 6 is unlimited fully, but window member 8 these sides are but also not unlimited fully.In addition, the bonding state with bossing 2e protecgulum 2 convex bound fraction 5e of over cap 5 still continues to keep.And ball 11 1 applies clamping force in the face of over cap 5, and one side embeds in the recess 5f2.Between this accurate open position P3 and next open position P4, on the position that the switch (not shown) of the power supply of open and close camera is transformed into out by switching manipulation parts 13, so lens barrel 6 just begins to stretch to the position that can photograph.
Then, shown in Fig. 5, Fig. 9 (D), when over cap moves a bit to-directions X slightly again, when reaching open position P4, the front of lens barrel 6 still keeps opening-wide state constant, and window member 8 has been opened fully.Lens barrel 6 is in the state that reaches the position that can photograph, and determines the state that can photograph at this.In addition, the bonding state of the bossing 2e of the convex bound fraction 5e of over cap 5 and protecgulum 2 still continues to remain unchanged.Then, ball 13 embeds in the recess 592, and over cap 5 remains on the above-mentioned open position P4 with predetermined clamping force.
Over cap 5 be in near the above-mentioned half-open position P2 to above-mentioned accurate open position P3, further arrive again under the state in the moving range of open position P4, convex bound fraction 5e is in the state that combines with the bossing 2e of protecgulum 2.Therefore; even because the fore-end of 11,12 pairs of over caps 5 of ball applies the power to+Z direction; perhaps; because the user has inadvertently applied power to+Z direction at the fore-end of over cap 5; the left side of over cap 5 (+X side) can (front of protecgulum 2) not break away from from the camera front yet; prevented over cap 5 rocking forwards, in addition, also prevented the front of the end, right side (X side) of over cap 5 near camera.
In addition; be in from off-position P1 and move to over cap 5 in the moving range between the open position P4; the crimping slipping plane part 5d of inside surface one side of over cap (one side relative with protecgulum 2) remains on the very little state of specified gap with respect to the protuberance 8d of window member 8.Therefore; even inadvertently on over cap 5, applied external force to+Z direction; because the part of above-mentioned crimping slipping plane part 5d is crimped on the raised part 8d, the other parts of over cap 5 also can not be crimped on the surface of protecgulum 2, thereby have protected protecgulum 2.In addition, when over cap 5 is shown in an open position P4, because above-mentioned crimping slipping plane part 5d is crimped on because of there being protuberance 8d to thicken on the protuberance 8e of so many wall thickness, so over cap 5 still can remain near and the state that do not rock of front end.
After photography is finished; camera 1 is under the situation of collecting state; make over cap 5 when open position P4 moves to accurate open position P3, the switch (not shown) of the open and close power supply of camera just is transformed into off-position, and lens barrel begins to be retracted into retracted position.On the accurate open position P3 of over cap 5,, before the indentation action of lens barrel 6, can prevent closing of over cap 5 owing to there is the predetermined clamping force of ball 11 generations to act on the over cap.After lens barrel 6 pinch ins, over cap 5 is on the position that off-position P1 slides, and camera just is in non-photography state.
In addition; the over cap 5 of the camera 1 in the foregoing description; be along being arranged on sliding on the protecgulum 2 along the straightaway gathering sill 2b of directions X, 2c; but; be not limited in this; over cap supporting structure in the foregoing description also goes for above-mentioned gathering sill is made curve shape, the camera of the structure that over cap then slides along the gathering sill of this curve shape.In this case, must use the convex bound fraction with the corresponding parallel curve form of the gathering sill of above-mentioned curve shape, with replacement be arranged on the over cap 5 along the straightaway convex bound fraction of directions X 5e.
In addition, on the protecgulum 2 and over cap 5 of the camera 1 of the foregoing description, bossing 2e that interosculates and convex bound fraction 5e in conjunction with crimping face, make vertical plane (see figure 7) along the Z direction.In addition, can form (seeing Fig. 7,8) by the plane with thick crowning 8d, the 8e of the window member 8 of protecgulum 2 one sides of the crimping slipping plane 5d crimping of inside surface one side of over cap 5.But, also proposed relatively therewith, making above-mentioned bossing 2e and above-mentioned convex bound fraction 5e with respect to the Z direction is the face (dovetail face) that tilts, and the modified example of above-mentioned thick crowning 8d, 8e being made the curved surface of regulation curvature.Figure 10 is the sectional drawing of the bonding state of the protecgulum of above-mentioned modified example and over cap.
In the above-mentioned modified example shown in Figure 10, the slipping plane 2e1 ' of the bossing 2e ' of protecgulum 2, and the crimping slipping plane 5e1 ' of the convex bound fraction 5e ' of over cap 5 makes mutually to the dip plane of same direction (the only face that tilts to the Y direction).In addition, can with crowning 8d ', the 8e ' of the heavy wall of the window member 8 of the crimping slipping plane 5d ' crimping of over cap 5, its section is also made curved surface.
According to the camera that uses this modified example, can obtain the effect same with the foregoing description, particularly, can make over cap keep stable status, and the slide of over cap can successfully carry out.
According to above-described the present invention, provide a kind of length of bound fraction of the usefulness that leads not proportional in the length of glide direction with over cap, can stably carry out slide, and over cap is at the also infrequent camera of rocking of optical axis direction.
