The electronic circuit unit 30 can be inserted into and removed from the housing portion 11 of the housing 10 in one direction (also referred to as an AB direction or an insertion / extraction direction in the illustrated example). Although the insertion / extraction direction of the electronic circuit unit 30 should just be set to the direction which cross | intersects a perpendicular direction (up-down direction in FIG. 1), in this embodiment, it is set to the direction orthogonal to a perpendicular direction. The front surface 10a of the housing 10 may be parallel to the vertical direction as shown in FIG. 1, but is not limited thereto.

  The accommodating portion 11 of the present embodiment can accommodate a plurality of electronic circuit units 30. That is, the accommodating portion 11 has a plurality of accommodating areas 13 that accommodate the electronic circuit units 30. The accommodating part 11 of this embodiment is formed vertically long so that a plurality of electronic circuit units 30 can be accommodated side by side in the vertical direction (the height direction of the housing 10). Further, the dimension between the pair of inner side surfaces 11b extending in the insertion / extraction direction (AB direction) of the electronic circuit unit 30 in the accommodating part 11 (the width dimension of the accommodating part 11) is the width of the electronic circuit unit 30 described later. It is set to be approximately equal to the dimension or slightly larger than the width dimension.

The pair of inner side surfaces 11b of the housing portion 11 is provided with a housing-side guide rail 12 (housing-side track) that extends linearly along the insertion / extraction direction of the electronic circuit unit 30. The pair of housing side guide rails 12 are located at the same height. The pair of housing-side guide rails 12 support the electronic circuit unit 30 when the electronic circuit unit 30 is inserted into and removed from the housing portion 11 in the insertion / extraction direction and in a state where the electronic circuit unit 30 is housed in the housing portion 11. . The length dimension of each housing side guide rail 12 along the insertion / extraction direction may be set equal to or slightly shorter than the length dimension of the inner side surface 11b along the insertion / extraction direction. The specific shape and the like of the housing side guide rail 12 may be arbitrary.
In the present embodiment, a plurality of a pair of housing side guide rails 12 are arranged at a certain interval in the height direction of the housing 10 in accordance with the number of electronic circuit units 30 housed in the housing portion 11. .

The sliding surface 86 extends so as to incline in the radial direction of the shaft portion 45 as it moves away from the locking surface 85 described above in the circumferential direction of the shaft portion 45.
Accordingly, when the electronic circuit unit 30 is rotated in the first rotation direction RO1 in a state where the locking projection 81 is accommodated in the locking recess 84, the locking projection 81 is a sliding surface of the locking recess 84. By moving on the sliding surface 86 in a state of being in contact with the 86, the restricting locked portion 82 moves from the locking position HA1 to the locking release position HA2 against the biasing force of the biasing member 83. (See especially FIG. 5). That is, the sliding surface 86 of each locking recess 84 allows the electronic circuit unit 30 to rotate in the first rotation direction RO1.

  The restricting locked portion 82 of the present embodiment is formed integrally with the unit side guide rail 32 in the same manner as the holding locked portion 62. In the present embodiment, the unit-side guide rail 32 can be rotated between the reference position RA1 and the rotation position RA2 with respect to the unit main body 31 as described above, and thus the locked portion 82 for regulation. Is movable between the locking position HA1 and the locking release position HA2. The locking position HA1 of the restricting locked portion 82 corresponds to the reference position RA1 of the unit side guide rail, and the locking releasing position HA2 of the restricting locked portion 82 corresponds to the rotation position RA2 of the unit side guide rail. To do.

Further, in the present embodiment, the biasing member 83 that biases the restricting locked portion 82 toward the locking position HA1 biases the holding locked portion 62 toward the locking position HA1. The same as the force member 63.
Further, the restricting locked portion 82 of the present embodiment is formed integrally with the holding locked portion 62. Specifically, the plurality of locking recesses 84 of the restricting locked portion 82 are arranged adjacent to the locking recess 64 of the holding locked portion 62 in the circumferential direction of the shaft portion 45. (See FIG. 3 in particular).

The restriction release mechanism 90 releases the movement restriction of the electronic circuit unit in the second rotation direction RO2 by the movement direction restriction mechanism 80 described above.
The restriction release mechanism 90 includes an operation unit 91 that operates the movement direction restriction mechanism 80 to release the movement restriction of the electronic circuit unit 30 in the second rotation direction RO2. In the present embodiment, the operation unit 91 of the restriction release mechanism 90 is configured by a predetermined portion of the unit side guide rail 32 that is the same as the operation unit 71 of the holding release mechanism 70. For this reason, the operation direction of the operation unit 91 that releases the movement restriction of the electronic circuit unit 30 in the second rotation direction RO <b> 2 is the same as the operation direction of the operation unit 71 of the holding release mechanism 70.

  Next, a method of inserting / removing the electronic circuit unit 30 with respect to the housing portion 11 of the housing 10 in the electronic device apparatus 1 having the above configuration will be described.

  When the electronic circuit unit 30 is accommodated in the accommodating portion 11, first, as shown in FIGS. 1 and 3, the pair of shaft portions 45 of the electronic circuit unit 30 is paired with the pair of housings 10 arranged at the protruding position F <b> 1. The electronic circuit unit is disposed at the hanging position U1 by being engaged with the hook portion 40. At this time, since the hook portion 40 is held at the protruding position F1 outside the housing portion 11 by the lock mechanism 50 (specifically, the locking member 51 disposed at the lock position L1), the shaft portion 45 is stably provided. Can be locked to the hook portion 40. In a state where the electronic circuit unit 30 is arranged at the hanging position U1, the electronic circuit unit 30 will not fall even if the operator releases the electronic circuit unit 30.

  Further, when the electronic circuit unit 30 is disposed at the hanging position U1, the locking protrusion 81 (61) of the housing 10 is connected to the hanging position of the restriction locked portion 82 provided on the electronic circuit unit 30. Enter the stop recess 84A. In a state where the locking projection 81 (61) of the housing 10 enters the hanging position locking recess 84A, the locking projection 81 (61) contacts the locking surface 85 of the hanging position locking recess 84A. The electronic circuit unit 30 does not further rotate from the hanging position U1 in the second rotation direction RO2 (direction away from the insertion / extraction position U4).

  Next, the electronic circuit unit 30 is rotated in the first rotation direction RO1 around the pair of shaft portions 45 locked to the pair of hook portions 40 from the hanging position U1 to the insertion / extraction position U4. At this time, since the pair of hook portions 40 is held at the protruding position F1 by the lock mechanism 50, the electronic circuit unit 30 can be rotated in a stable state.

  The rotation of the electronic circuit unit 30 in the first rotation direction RO1 is not blocked by the movement direction regulating mechanism 80. More specifically, as shown in FIGS. 1, 3, 4, and 6, the locking projections 81 (61) are provided with the respective locking recesses 84 (hanging position locking recesses 84A and When the electronic circuit unit 30 is rotated in the first rotation direction RO1 from the state where it enters the intermediate position locking recesses 84B, 84C), that is, the state where the restriction locked portion 82 is disposed at the locking position HA1. In this state, the locking projection 81 (61) moves on the sliding surface 86 in a state where the locking projection 81 (61) is in contact with the sliding surface 86 of the locking recess 84. As a result, the restricting locked portion 82 moves from the locking position HA1 to the locking release position HA2 against the biasing force of the biasing member 83 (63) as illustrated in FIG. In other words, the locking projection 81 (61) can come out of the locking recess 84.

  Further, when the electronic circuit unit 30 is rotated in the first rotation direction RO1, the locking projection 81 (61) comes out of the hanging position locking recess 84A, and as shown in FIG. ) And the second intermediate position locking recess 84B, and the second intermediate position locking recess 84B is pulled out from the first intermediate position locking recess 84B as shown in FIG. 6 by the biasing force of the biasing member 83 (63). In the state of entering the midway position locking recess 84C, the locking projection 81 (61) contacts the locking surface 85 of the first midway position locking recess 84B or the second midway position locking recess 84C. For this reason, the electronic circuit unit 30 does not rotate in the second rotation direction RO2 (direction approaching the suspension position U1) from the midway positions U2 and U3. Thereby, the operator can interrupt the operation | work which rotates the electronic circuit unit 30 from the hanging position U1 to the insertion / extraction position U4, and can release a hand from the electronic circuit unit 30. FIG.

  As shown in FIG. 7, when the electronic circuit unit 30 has reached the insertion / extraction position U <b> 4, the electronic circuit unit 30 is held at the insertion / extraction position U <b> 4 by the position holding mechanism 60. More specifically, when the electronic circuit unit 30 reaches the insertion / extraction position U4, the locking projection 61 (81) that has come out of the second mid-position locking recess 84C is formed on the biasing member 63 (83). The retaining recessed portion 64 of the retaining portion 62 is held by the urging force. In this state, the locking protrusion 61 (81) contacts the locking surface 65 of the locking recess 64 of the holding locked portion 62, so that the electronic circuit unit 30 is moved from the insertion / extraction position U4 in the second rotation direction RO2. It does not rotate.

  Further, when the electronic circuit unit 30 reaches the insertion / extraction position U4, the lock release mechanism 55 releases the holding of the pair of hook portions 40 at the protruding position F1 by the lock mechanism 50. More specifically, when the electronic circuit unit 30 reaches the insertion / extraction position U4, the front portion 34 of the unit main body 31 enters the housing region 13 of the housing portion 11, so that the locking member 51 is The front portion 34 of the main body 31 is pushed out of the lock position L1 (see FIG. 3) in the storage area 13 to the lock release position L2 outside the storage area 13. Thereby, a pair of hook part 40 becomes movable in the insertion / extraction direction (AB direction) of the electronic circuit unit 30 between the protrusion position F1 and the accommodation position F2 inside the accommodating part 11. FIG. Since the locking projection 61 (81) is formed integrally with the hook portion 40, it can be moved in the insertion / extraction direction of the electronic circuit unit 30 as with the hook portion 40.

Finally, as shown in FIGS. 7 and 8, the electronic circuit unit 30 is moved from the insertion / removal position U4 in the insertion direction (A direction), and the electronic circuit unit 30 is inserted into the housing portion 11 to The operation of accommodating in the accommodating portion 11 is completed.
When the electronic circuit unit 30 is inserted into the housing portion 11, the hook portion 40 and the locking protrusion 61 (81) can move in the insertion / extraction direction of the electronic circuit unit 30. It is accommodated in the accommodating portion 11 in a state where it is engaged with the hook portion 40 and in a state where the engaging projection 61 (81) is engaged with the retained portion 62 for holding of the electronic circuit unit 30. Further, when the electronic circuit unit 30 is inserted into the housing portion 11, the unit-side guide rail 32 of the electronic circuit unit 30 is moved to the reference position as the holding locked portion 62 is arranged at the locking position HA1. Since it is arranged in RA1, the unit side guide rail 32 can be slid along the length direction of the housing side guide rail 12.

On the other hand, when the electronic circuit unit 30 is taken out from the accommodating portion 11, first, the electronic circuit unit 30 is moved in the extraction direction (B direction) to reach the insertion / extraction position U4 outside the accommodating portion 11. At this time, since the shaft portion 45 of the electronic circuit unit is locked to the hook portion 40, the locking protrusion 61 (81) is locked to the holding locked portion 62 of the electronic circuit unit 30. Therefore, the hook portion 40 and the locking protrusion 61 (81) move in the extraction direction together with the electronic circuit unit 30, and reach the protruding position F1 corresponding to the insertion / extraction position U4 of the electronic circuit unit 30. When moving the electronic circuit unit 30 in the extraction direction, the operator may hold the grip portion 33 provided on the front end surface 31a of the unit body 31, for example.
In a state where the electronic circuit unit 30 has reached the insertion / extraction position U4, the electronic circuit unit 30 is positioned outside the accommodating portion 11, but the locking protrusion 61 (81) is locked to the holding locked portion 62. Thus, the electronic circuit unit 30 is held at the insertion / extraction position U4.

Next, the electronic circuit unit 30 is rotated in the second rotation direction RO2 around the pair of shaft portions 45 locked to the pair of hook portions 40 from the insertion / extraction position U4 to the suspension position U1 (FIGS. 1 and 4). To 6).
At this time, as shown in FIG. 9, the holding release mechanism 70 releases the holding of the electronic circuit unit 30 to the insertion / extraction position U <b> 4 by the position holding mechanism 60. Further, the restriction release mechanism 90 releases the movement restriction of the electronic circuit unit 30 in the second rotation direction RO2 by the movement direction restriction mechanism 80. Specifically, by operating the operation portions 71 and 91 as the holding release mechanism 70 and the restriction releasing mechanism 90 with the fingers of the operator or the like, the holding locked portion 62 and the locking locked portion 82 are locked. The position is moved from the position HA1 to the unlocking position HA2. In the present embodiment, the operation units 71 and 91 are provided on the front end surface 31a side of the unit main body 31, and the operation direction of the operation units 71 and 91 is a direction from the upper surface side to the lower surface side of the unit main body 31 (vertical in FIG. Direction downward). Therefore, the operator can easily operate the operation units 71 and 91 while supporting the part of the unit main body 31 on the side of the front end surface 31a with his / her hand.

  Then, when the electronic circuit unit 30 is rotated from the insertion / extraction position U4 to the suspension position U1, as shown in FIGS. 4 and 6, for example, the electronic circuit unit 30 is disposed at midway positions U2 and U3. The movement direction restriction mechanism 80 may restrict the movement of the electronic circuit unit 30 in the second rotation direction RO2. Specifically, by releasing the operation of the operation portion 91 (71) of the restriction release mechanism 90 by the operator, the locked portion 82 for restriction is locked by the biasing force of the biasing member 83 (63). You may move from HA2 to the latching position HA1. In this case, the operator can interrupt the work of rotating the electronic circuit unit 30 from the insertion / extraction position U4 to the suspension position U1 and release the hand from the electronic circuit unit 30.

  As described above, when the electronic circuit unit 30 is rotated from the insertion / extraction position U4 to the hanging position U1, particularly when the electronic circuit unit 30 is separated from the insertion / extraction position U4, the lock mechanism 50 causes the pair of hook portions 40 and the engagement. The stop protrusions 61 and 81 are held at the protruding position F1. Specifically, when the electronic circuit unit 30 moves away from the insertion / extraction position U4, the front portion 34 of the unit body 31 moves from the inside of the housing area 13 of the housing portion 11 to the outside of the housing area 13, so that the unit body The pushing of the locking member 51 to the outside of the accommodation region 13 by the front side portion 34 of 31 is released. Thereby, the locking member 51 is returned to the lock position L1 in the accommodation region 13 by the urging force of the urging member 52 (see FIG. 3), and the pair of hook portions 40 and the locking protrusions 61 and 81 are moved to the protruding position F1. Hold on. Thereby, the electronic circuit unit 30 can be rotated in the second rotation direction RO2 in a stable state.

Finally, as shown in FIGS. 1 and 3, the electronic circuit unit 30 disposed at the hanging position U <b> 1 is removed from the housing 10, thereby completing the operation of taking out the electronic circuit unit 30 from the housing portion 11.
When removing the electronic circuit unit 30 from the housing 10, for example, by lifting the electronic circuit unit 30 vertically upward, the pair of shaft portions 45 of the electronic circuit unit 30 and the pair of hook portions 40 of the housing 10. It is only necessary to release the locked state and to pull out the locking projection 81 (61) from the suspended position locking recess 84A.

  As described above, according to the electronic device device 1 of the present embodiment, a pair of hook portions 40 provided in the housing 10 and a pair of hooks 40 provided in the electronic circuit unit 30 and engageable with the pair of hook portions 40. Therefore, the operator can let go of the electronic circuit unit 30 in a state where the electronic circuit unit 30 is arranged at the suspended position U1. That is, the operator can let go of the electronic circuit unit 30 during the insertion / extraction operation of the electronic circuit unit 30. Therefore, the insertion / extraction operation of the electronic circuit unit 30 with respect to the accommodating portion 11 can be easily performed. This effect is particularly effective when the housing portion 11 of the housing 10 is at a high position.

Moreover, according to the electronic device apparatus 1 of the present embodiment, the electronic circuit unit 30 is disposed in the suspended position U1 by including the movement direction regulating mechanism 80, and the electronic circuit unit 30 is in the middle position U2, Even if the worker releases the electronic circuit unit 30 in the state of being arranged at U3, the electronic circuit unit 30 does not move in the second rotation direction RO2. For this reason, the operator can let go of the electronic circuit unit 30 even in the state where the electronic circuit unit 30 is arranged at the midway positions U2 and U3. Therefore, the insertion / extraction work of the electronic circuit unit 30 with respect to the accommodating part 11 can be performed more easily.
Further, by providing the movement direction regulating mechanism 80, the electronic circuit unit 30 can be reliably prevented from colliding with the housing 10 or another electronic circuit unit housed in another housing portion of the housing 10. .

  Furthermore, according to the electronic device device 1 of the present embodiment, by including the restriction release mechanism 90, the movement restriction of the electronic circuit unit 30 in the second rotation direction RO2 by the movement direction restriction mechanism 80 can be released. . That is, the electronic circuit unit 30 can be moved in the second rotational direction RO2, and the removal operation of the electronic circuit unit 30 can be easily performed.

Moreover, according to the electronic device apparatus 1 of the present embodiment, the electronic circuit unit 30 is moved from the suspended position U1 or the accommodating portion 11 to the insertion / extraction position U4 by providing the position holding mechanism 60, and the electronic circuit. The unit 30 can be held at the insertion / extraction position U4. For this reason, the operator can let go of the electronic circuit unit 30 also in the state which has arranged the electronic circuit unit 30 in the insertion / extraction position U4. Therefore, the insertion / extraction work of the electronic circuit unit 30 with respect to the accommodating part 11 can be performed more easily.
In addition, by providing the position holding mechanism 60, the front-rear direction of the electronic circuit unit 30 can be easily matched with the insertion / removal direction with respect to the housing portion 11 simply by moving the electronic circuit unit 30 from the hanging position U1 to the insertion / extraction position U4. Can do. In other words, it is not necessary for the operator to adjust the orientation of the electronic circuit unit 30 so that the front-rear direction of the electronic circuit unit 30 matches the insertion / extraction direction with respect to the housing portion 11. Therefore, the electronic circuit unit 30 can be easily accommodated in the accommodating portion 11.

  Furthermore, according to the electronic device apparatus 1 of the present embodiment, the holding release mechanism 70 is provided, so that the holding of the electronic circuit unit 30 to the insertion / extraction position U4 by the position holding mechanism 60 can be released. That is, the electronic circuit unit 30 can be moved from the insertion / extraction position U4 to the suspension position U1, and the removal operation of the electronic circuit unit 30 can be easily performed.

Further, according to the electronic device device 1 of the present embodiment, the pair of hook portions 40 and the locking projections 61 and 81 are electronic between the projecting position F1 outside the housing portion 11 and the housing position F2 inside the housing portion 11. The circuit unit 30 can be moved in the insertion / extraction direction. Therefore, in a state where the pair of shaft portions 45 of the electronic circuit unit 30 are locked to the pair of hook portions 40, the locking protrusions 61 (81) are engaged with the held locked portions 62 of the electronic circuit unit 30. In a stopped state, the pair of hook portions 40 and the locking projections 61 (81) can be moved together with the electronic circuit unit 30 in the insertion / removal direction with respect to the housing portion 11. That is, the insertion / extraction operation of the electronic circuit unit 30 with respect to the housing portion 11 can be performed more easily.
Further, since the pair of hook portions 40 and the locking projections 61 and 81 are accommodated in the accommodating portion 11, various operations such as operation of the electronic device 1 by the operator can be performed by the pair of hook portions 40 and the locking projections 61. , 81 can be prevented. That is, various operations such as operation of the electronic device apparatus 1 by an operator can be performed smoothly.

Furthermore, according to the electronic device device 1 of the present embodiment, since the pair of hook portions 40 can be held at the protruding position F1 by including the lock mechanism 50, the electronic circuit unit 30 can be held in a stable state with the suspension position U1. It can be rotated between the insertion / extraction position U4. That is, the insertion / extraction operation of the electronic circuit unit 30 can be performed more easily.
Moreover, according to the electronic device apparatus 1 of this embodiment, by providing the lock release mechanism 55, the pair of hooks by the lock mechanism 50 can be obtained simply by rotating the electronic circuit unit 30 from the hanging position U1 to the insertion / extraction position U4. The holding | maintenance to the protrusion position F1 of the part 40 can be cancelled | released. For this reason, after the electronic circuit unit 30 has reached the insertion / extraction position U4, the pair of hook portions 40 can be moved together with the electronic circuit unit 30 in the insertion / extraction direction together with the electronic circuit unit 30.

Furthermore, according to the electronic device apparatus 1 of the present embodiment, since the operation units 71 and 91 as the holding release mechanism 70 and the regulation release mechanism 90 are provided in the electronic circuit unit 30, the operator has the electronic circuit unit 30.

Regulations can be lifted. That is, the electronic circuit unit 30 can be removed from the housing 10 more easily.
In addition, since the operation units 71 and 91 are not operated when the operator releases the electronic circuit unit 30, the holding of the electronic circuit unit 30 to the insertion / extraction position U4 by the position holding mechanism 60 is unexpectedly released or the movement direction is restricted. It is possible to prevent the movement restriction of the electronic circuit unit 30 in the second rotation direction RO2 by the mechanism 80 from being released unexpectedly.

[Second Embodiment]
Next, a second embodiment of the present invention will be described focusing on differences from the first embodiment with reference to FIG. In addition, about the structure which is common in 1st embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

As shown in FIG. 10, the electronic device apparatus 1 </ b> A according to the present embodiment is configured in the same manner as the electronic apparatus device 1 of the first embodiment. In addition, in the electronic apparatus device 1A of the present embodiment, the holding locked portion 62 and the locking locked portion 82 arranged at the locking release position HA2 further move away from the locking position HA1. A release operation restricting unit 100 that restricts this is provided.
For example, the release operation restricting unit 100 may be a member that is provided in the unit main body 31 and restricts the unit-side guide rail 32 disposed at the rotation position RA2 from moving further away from the reference position RA1. However, in the present embodiment, the holding member 62 for holding extending in the circumferential direction of the shaft 45 and the restricting member 101 having an arc shape extending in parallel with the locking member 82 for restriction are included.

  The restricting member 101 is formed integrally with the holding latched portion 62 and the regulating latched portion 82, and the locking recess 64 of the holding latched portion 62 and the latching recess of the regulating latched portion 82 are formed. 84 (particularly, the intermediate position locking recesses 84B and 84C) is located on the radially inner side of the shaft portion 45. The interval between the restricting member 101 and the holding locked portion 62 or the locking locked portion 82 may be set small as long as the locking protrusions 61 and 81 can enter between them.

According to the electronic apparatus device 1A of the present embodiment, when the holding locked portion 62 and the locking locked portion 82 are moved from the locking position HA1 to the locking release position HA2 by the operator's operation, It is possible to prevent the locked portion 62 for restriction and the locked portion 82 for regulation from being excessively separated from the locking protrusions 61 and 81. For this reason, when the above-described operation of the operator is released, the holding locked portion 62 and the locking locked portion 82 are quickly returned to the locking position HA1 by the biasing force of the biasing members 63 and 83. be able to.
As a result, even if the operator releases the operation and releases the electronic circuit unit 30 while the electronic circuit unit 30 is located on the insertion / extraction position U4 side from the suspension position U1, the locking protrusion 61, 81 becomes easy to latch in the latching recessed part 64 of the latching part 62 for holding, and the latching recessed part 84 of the latching part 82 for regulation. That is, when the electronic circuit unit 30 is located closer to the insertion / extraction position U4 than the suspension position U1, the electronic circuit unit 30 is suspended even if the operator releases the operation and simultaneously releases the hand from the electronic circuit unit 30. It is possible to effectively suppress a large movement toward the position U1.

  Although the details of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

The locking protrusion 61 of the position holding mechanism 60 may be provided separately from the locking protrusion 81 of the movement direction restricting mechanism 80, for example, as shown in FIG. In this case, the holding portion 62 for holding of the position holding mechanism 60 may be provided separately from the locking portion 82 for restriction of the movement direction restricting mechanism 80.
The holding locked portion 62 illustrated in FIG. 11 is a housing in which the locking protrusion 61 of the position holding mechanism 60 is inserted when the electronic circuit unit 30 is rotated from the suspension position U1 side to the insertion / extraction position U4. A recess 67 is provided. The housing recess 67 opens in the circumferential direction of the shaft portion 45 so that the locking protrusion 61 enters when the electronic circuit unit 30 is made to reach the insertion / extraction position U4 from the suspension position U1 side.

  The holding engaged portion 62 is provided with a closing portion 68 that closes and opens the opening of the accommodating recess 67. The closing portion 68 is provided so as to be rotatable between a position CL for closing the opening of the housing recess 67 with respect to the held portion 62 for holding and a position OP for opening the opening of the housing recess 67. The rotation direction of the closing part 68 from the closing position CL to the opening position OP is a direction entering the inside of the housing recess 67, and the closing part 68 cannot move outside the housing recess 67. The closing portion 68 is urged toward the closing position CL by an urging member (not shown) (for example, a torsion spring).

  In the electronic apparatus device 1B illustrated in FIG. 11, when the electronic circuit unit 30 is moved from the hanging position U1 side to the insertion / extraction position U4, the position holding mechanism 60 is locked without being obstructed by the closing portion 68. The protrusion 61 can be housed in the housing recess 67. In a state where the electronic circuit unit 30 is disposed at the insertion / extraction position U4 and the locking projection 61 of the position holding mechanism 60 is accommodated in the accommodation recess 67, the closing portion 68 is disposed at the position CL closed by the urging force of the urging member. Is done. Even if the electronic circuit unit 30 is to be rotated toward the suspended position U <b> 1 in this state, the blocking protrusion 68 prevents the locking protrusion 61 from coming out of the housing recess 67. That is, the position holding mechanism 60 illustrated in FIG. 11 holds the electronic circuit unit 30 at the insertion / extraction position U4 as in the above embodiment.

Similarly to the embodiment, the movable member can be moved between a locking position HA1 that is locked to the locking protrusions 61 and 81 and a locking release position HA2 that is not locked to the locking protrusions 61 and 81. Further, the holding locked portion 62 and the restricting locked portion 82 are biased toward the locking position HA1 by the same biasing members 63C and 83C.
On the other hand, the gripping portion 33C as the operation portions 71 and 91 of the holding release mechanism 70 and the restriction release mechanism 90 is arranged in the front-rear direction of the unit body 31 so as to be close to and away from the front end surface 31a of the unit body 31 (in FIG. Direction).

  Then, the holding locked portion 62 and the regulating locked portion 82 are held when the gripping portion 33C is moved in the front-rear direction of the unit body 31. Is connected to the gripping portion 33C so as to move between the locking position HA1 and the locking release position HA2. Specifically, when the gripping portion 33C moves away from the front end surface 31a of the unit main body 31, the holding locked portion 62 and the restricting locked portion 82 are engaged from the locking release position HA2 side. It moves toward the stop position HA1. Conversely, when the gripping portion 33C moves in a direction approaching the front end surface 31a of the unit body 31, the holding locked portion 62 and the regulated locked portion 82 are moved from the locking position HA1 side toward the locking release position HA2. Move.

In the configuration illustrated in FIG. 12, the grip portion 33C is formed integrally with the unit side guide rail 32, and the unit side guide rail 32 is movable in the front-rear direction of the unit body 31 together with the grip portion 33C. In addition, the gripping portion 33 </ b> C is connected to the holding locked portion 62 and the locking locked portion 82 via the unit side guide rail 32.
