The lock plate 120 corresponds to an example of the engaged portion of the present invention, and is provided at four places in total at two places on the upper and lower sides in the width direction of the unit side connector 121. The lock lever 119 corresponds to an example of the operation member of the present invention.

  FIG. 7A is a view of the lock state of the lock mechanism as viewed from the front side of the separation unit 102, and FIG. 7B is a view of the lock release state of the lock mechanism as viewed from the front side of the separation unit 102. FIG. 8A is a cross-sectional view showing the state of the upper lock plate 120 in the unlocked state of the lock mechanism, and FIG. 8B shows the state of the lower lock plate 120 in the unlocked state of the lock mechanism. FIG.

  In the locked state of the lock mechanism shown in FIG. 7A, the lock lever 119 is housed in the base portion 117, and the lock plate 120 protrudes from the base portion 117. In this locked state, as shown in FIG. 7B, when the lock lever 119 is operated to raise in the direction of the arrow, the lock plate 120 connected via the cam member interlocks with the operation of the lock lever 119 is the upper side. To be raised. Then, the lock lever 119 abuts on the mechanical end to stop the rotation, and thereby the lock release state is established. At this time, the lock plate 120 is housed inside the base portion 117, as shown in FIG.

  FIG. 9 is a cross-sectional enlarged view taken along the line B-B in FIG. As shown in FIG. 9, the unit-side connector 121 is mounted on the substrate 121 a inside the separation unit 102, and exposed and disposed in the recess 123 provided in the base portion 117. The unit-side connector 121 is covered by the connector guard 124 on the entire circumference, and the tip of the connector guard 124 protrudes beyond the unit-side connector 121.

  The both side walls 1231 of the recessed part 123 are formed in the taper inner wall shape which becomes narrow gradually toward an inside. At this time, the tip of the connector guard 124 is disposed on the inner side (rear side) of the surface on the front side of the separation unit 102, and the unit side connector 121 and the connector guard 124 are disposed in the recess 123 of the base portion 117. .

  FIG. 10 is a front view of the separation unit 102. As shown in FIG. The unit-side connector 121 can move integrally with the connector guard 124 in the width direction and height direction orthogonal to the optical axis of the camera body 101 with respect to the base portion 117 as shown by the arrow in FIG. It is held inside.

  Further, in the separation unit 102, as shown in FIG. 10, the tip end of the lock plate 120 protruding from the base portion 117 in the locked state and the tip end of the convex portion 122 are disposed inside the outermost shape of the base portion 117 There is. The lock lever 119 is also housed inside the base portion 117 in the locked state. That is, all the components of the separation unit 102 are disposed inside the outermost portion of the base portion 117. The outer shape of the base portion 117 is also substantially the same as that of the battery attachment portion 118, so that the separation unit 102 can be configured to be very compact in the width direction and the height direction. As a result, the main body side connection portion 106 can also be configured to be small, and miniaturization of the entire camera 100 is achieved.

  Next, with reference to FIG. 11, a method of mounting the separation unit 102 on the main body side connection portion of the camera body 101 will be described.

  When attaching the separation unit 102 to the main body side connection portion 106, first, the convex portion 122 of the separation unit 102 is set in the guide groove 114 of the main body side connection portion 106 in the arrow direction (optical axis direction) of FIG. Insert to fit. At this time, the lock mechanism is in the unlocked state in which the lock lever 119 is raised by the user operation.

  Since the guide groove 114 is formed in a crank shape, when the convex portion 122 is inserted into the guide groove 114, the convex portion 122 abuts on the crank shaped portion of the guide groove 114. In the state where the convex portion 122 abuts on the crank shaped portion of the guide groove 114, as shown in FIG. 11B, the separation unit 102 is moved downward (arrow in the figure) along the crank shape of the guide groove 114. . Thereby, the main body side connector 110 and the unit side connector 121 are positioned at the connection position.

  Then, after the separation unit 102 is moved downward by a predetermined amount, the separation unit 102 is further moved in the optical axis direction (arrow direction) as shown in FIG. The connector 121 is inserted and electrically connected. At this time, the tapered outer wall shaped convex portion of the protective wall 111 around the main body side connector 110 is fitted in the tapered inner wall shaped recess 123 of the unit side connector 121 and positioned.

  Further, as described above, the unit-side connector 121 is held movably in the width direction and the height direction with respect to the base portion 117. The movable amount of the unit-side connector 121 is set to a sufficiently large amount with respect to the amount of rattling at the time of connection and the amount of variation in the size of the component parts. Therefore, even if the positions of the main body side connector 110 and the unit side connector 121 are shifted, the unit side connector 121 can be easily inserted into the main body side connector 110. As a result, it is possible to absorb variations in the position relating to the attachment of the separation unit 102 and to reliably connect the connectors 121 and 110 with each other. Further, the connectors 121 and 110 can be connected without applying a large load, and the structure is excellent in reliability.

  After the main body side connector 110 and the unit side connector 121 are connected, when the separation unit 102 is further pushed in, the separation unit 102 abuts against a predetermined abutment portion of the main body side connection portion 106. Thereafter, the lock lever 119 is pushed in by the user operation to lock the lock mechanism. As a result, the lock plate 120 protruding from the base portion 117 is detachably engaged with the upper engaging portion 115 and the lower engaging portion 116 of the main body side connection portion 106, as shown in FIG. 11D. The camera body 101 and the separation unit 102 are mechanically connected.

  FIG. 12 (a) is a cross-sectional view of the main parts showing the relationship between the upper lock plate 120 and the upper locking portion 115 in a state in which the camera body 101 and the separation unit 102 are locked, FIG. 12 (b) is a lower lock FIG. 7 is a cross-sectional view of the main parts showing the relationship between the plate 120 and the lower locking portion 116.

  The upper locking portion 115 and the lower locking portion 116 are both open at the top, so that the camera body 101 and the separation unit 102 are mechanically connected by inserting the lock plate 120 from the top. Ru. Further, an inclined surface 1201 is formed at the tip of the lock plate 120. Therefore, even when the locking operation is performed in a state where the pressing of the separation unit 102 is insufficient, the separation unit 102 can be reliably locked because the separation unit 102 is pulled in by the slope 1201. In addition, in the connected state, the dimensions are set such that a predetermined gap is formed on the lower surface side of the separation unit 102 so that the connectors 121 and 110 can be reliably connected to each other.

  When removing the separation unit 102 from the main body side connection portion 106, first, the lock lever 119 is raised to bring the lock mechanism into the unlocked state. As a result, the lock plate 120 is housed inside the base portion 117, and the lock of the lock plate 120 with respect to the upper locking portion 115 and the lower locking portion 116, that is, the mechanical connection is released.

  In this state, the separation unit 102 is pulled out, the unit side connector 121 is separated from the main body side connector 110, and the electrical connection is released. Then, the protrusion 122 is moved along the guide groove 114 in the reverse procedure of mounting, and the separation unit 102 is removed.

  Next, with reference to FIGS. 13 to 15, the case where the separation unit 102 in the locked state is erroneously attached to the main body side connection portion 106 will be described.

  First, as shown in FIG. 13A, the convex portion 122 of the separation unit 102 is inserted in the direction of the arrow in the figure so as to align with the guide groove 114 of the main body side connection portion 106. At this time, since the lock mechanism is in the lock state, the lock plate 120 is in a state of being protruded from the base portion 117.

  In a state where the convex portion 122 abuts on the crank shaped portion of the guide groove 114, as shown in FIG. 13B, the separation unit 102 is moved downward (arrow in the figure) along the guide groove 114. In the locked state, as described above, since the lock plate 120 protrudes from the base portion 117, the lock plate 120 abuts on the lower wall 113 of the main body side connection portion 106 as shown in FIG.

  At this time, as shown in FIG. 15, the movement of the convex portion 122 in the crank-shaped guide groove 114 is restricted, and the separation unit 102 can not be assembled. In this state, since the main body side connector 110 and the unit side connector 121 are separated from each other, no load is applied to the connectors 110 and 121 even if they are assembled forcibly in the locked state, and the structure is high in reliability. ing.

  Next, load on the connectors 110 and 121 when a force is applied to the separation unit 102 in the locked state of the camera body 101 and the separation unit 102 will be described with reference to FIG.

  The connection portion of the main body side connector 110 and the unit side connector 121 is disposed inside the lock area 125 surrounded by the upper locking portion 115 and the lower locking portion 116, as shown in FIG. That is, since the lock is made at four places so as to surround the connectors 110 and 121, no load is applied to the connectors 110 and 121 from which direction the force is applied to the separation unit 102 side. Absent.

  In addition, even if a large force that deforms the lock plate 120 is applied to the separation unit 102, as described above, the main body side connection portion 106 can display the display portion 107, the right side terminal group 108, and the lower side terminal group. It is disposed in a recess surrounded by 109. That is, walls are present on both sides and the lower side in the width direction of the separation unit 102 in the connected state. Therefore, the base portion 117 abuts on the surrounding wall before the lock plate 120 is deformed and broken, and the wall receives a force.

  Thus, even if a large force that deforms the lock plate 120 is applied to the separation unit 102, the lock plate 120 is not broken. As a result, it is possible to prevent breakage of the connectors 110 and 121 without a large load being applied to the connectors 110 and 121, and the structure is highly reliable.

  Next, a case where the lock lever 119 is erroneously operated to the lock release position in a state where the camera body 101 and the separation unit 102 are connected will be described.

  In order to completely separate the separation unit 102 from the main body side connection portion 106, the convex portion 122 has to move the crank shaped portion of the guide groove 114 upward. Therefore, even if the lock of the lock mechanism is released, the separation unit 102 is configured such that the convex portion 122 is caught in the middle of the crank shaped portion of the guide groove 114 and stopped. That is, the separation unit 102 is not accidentally dropped and damaged, and the safety is excellent.

  Further, in the present embodiment, the connectors 110 and 121 for electrically connecting the camera body 101 and the separation unit 102 have a long shape in the height direction. Therefore, even if it is necessary to use the separation unit 102 having a large amount of communication information and a connector with more pins mounted, it is necessary to increase the size in the width direction of the camera body 101 simply by changing the body side connection portion 106. It is possible to realize an increase in the number of pins of the connection portion without doing so. In addition, since the exterior covers other than the main body side connection portion 106 can be diverted and used, the configuration is excellent in cost.

  As described above, in the present embodiment, even when the lock plate 120 is accidentally removed while the load on the connectors 110 and 121 for electrically connecting the camera body 101 and the separation unit 102 is reduced, the separation unit is separated. It is possible to prevent the 102 from falling. For this reason, it is possible to provide a highly reliable separation type camera 100.
