In the process of moving to the butting position, the movement of the second cabinet (4) is first guided by the first guide portion of the guide mechanism. As a result, the second cabinet (4) moves without contacting the first cabinet (3). Here, if the position and shape of the first guide portion are defined so that the second cabinet (4) does not interfere with the components on the chassis (7), the interference with the components on the chassis (7) is surely avoided. I can do it.

  Thereafter, the movement of the second cabinet (4) is guided by the second guide portion of the guide mechanism. As a result, the second cabinet (4) is brought into sliding contact with the first cabinet (3) at least at the end of the movement and moved to the abutting position with the first cabinet (3).

In the process in which the protrusion (6) slides from the first groove portion (51) of the rail groove (5) to the second groove portion (53) through the connecting groove portion (52) after avoiding interference with the upper part. The second cabinet (4) is in sliding contact with the sliding contact surface (32) of the first cabinet (3).

  In a more specific configuration, the first cabinet (3) and the second cabinet (4) are formed with an engagement receiving portion and an engagement portion that should be engaged with each other at the abutting position. In the process in which 4) is guided and moved by the first guide part, the engaging part is separated from the engagement receiving part, and the second cabinet (4) is guided and moved by the second guide part. In the process, the engagement portion engages with the engagement receiving portion.

  According to the specific configuration, the engagement portion engages with the engagement receiving portion in the process of moving the second cabinet (4) guided by the second guide portion, and finally the second cabinet (4). ) Is firmly connected to both the cabinets (3) and (4) in a state in which the first cabinet (3) is abutted with the first cabinet (3).

  According to the electronic device of the present invention, in the assembly process, the second cabinet slides while being guided by the first guide portion of the guide mechanism so that the second cabinet does not interfere with the components on the chassis. By prescribing the position and shape of one guide part, it is possible to reliably avoid interference with parts on the chassis, so there are more restrictions on the arrangement of parts to avoid interference with parts on the chassis than before. Will be alleviated.

Hereinafter, embodiments of the present invention implemented in a video camera will be described in detail with reference to the drawings.
In the video camera according to an embodiment of the present invention, as shown in FIGS. 1 and 2, the display unit (2) is supported on the side of the main body (1) via a hinge mechanism (8). (1) is provided with an objective lens (12) and a power button (11), and the display unit (2) is provided with a display (21).

  In the main body (1), the first cabinet (3) made of aluminum and the second cabinet (4) are brought into contact with each other to constitute most of the housing (13). A chassis (7) made of synthetic resin on which these parts are mounted is provided.

  In the assembly process of the video camera, the first cabinet (3) is attached to the chassis (7) in advance, and the second cabinet (4) is slid with respect to the chassis (7) so that both cabinets (3) ( 4) In order to guide the movement of the second cabinet (4) when butting each other, the chassis (7) is bent in a Z-shape or S-shape and extends parallel to each other as shown in FIG. Two rail grooves (5) and (5) are recessed, and the back surface of the second cabinet (4) is slidably engaged with the rail grooves (5) and (5) as shown in FIG. Two projections (6) and (6) to be joined are formed.

  As shown in FIG. 3, each rail groove (5) has a butt surface with the second cabinet (4) at a position away from the sliding contact surface (32) with the second cabinet (4) of the first cabinet (3). The second cabinet (4) is positioned close to the sliding surface (32) between the first groove (51) extending linearly toward (33) and the second cabinet (4) of the first cabinet (3). A second groove portion (53) extending linearly toward the abutment surface (33), and a connecting groove portion (52) extending in an oblique direction to connect the first groove portion (51) and the second groove portion (53) to each other. have.

  Further, as shown in FIG. 2, the first cabinet (3) has a pair of engagement receiving hooks (31) and (31) protruding from the opposite side of the second cabinet (4) with a space in the front and rear direction. Has been. On the other hand, as shown in FIG. 4, the second cabinet (4) is provided with a pair of engaging hooks (41) and (41) at a portion facing the first cabinet (3) with a space in the front-rear direction. ing. The engagement receiving hooks (31) (31) of the first cabinet (3) and the engagement hooks (41) (41) of the second cabinet (4) are the first cabinet (3) and the second cabinet (4). Are engaged with each other in a state where they face each other, and the cabinets (3) and (4) are firmly connected to each other.

In the above video camera, after the first cabinet (3) is attached to the chassis (7) as shown in FIG. 5 in the assembly process, the projections (6) and (6) of the second cabinet (4) are attached to the chassis (7). The second cabinet (4) is directed toward the butting surface (33) of the first cabinet (3) while being engaged with the starting ends of the first grooves (51) and (51) of the rail grooves (5) and (5). Press.
As a result, the projection (6), (6) of the second cabinet (4) is guided by the first grooves (51), (51) of the rail grooves (5), (5) of the chassis (7). Perform a linear slide move.

In the first linear slide movement, the second cabinet (4) moves on the straight line toward the abutting surface (33) without contacting the sliding contact surface (32) of the first cabinet (3). Thus, the protrusions 6 and 6 slide to the start ends of the connecting grooves 52 and 52 of the rail grooves 5 and 5.
In this process, among the two engagement hooks (41) and (41) shown in FIG. 4, the front engagement hook (41) is one of the two engagement receiving hooks (31) and (31) shown in FIG. It passes next to the rear engagement receiving hook (31).
Moreover, the convex part (42) of the 2nd cabinet (4) shown in FIG. 4 will pass the side of the components (71) on a chassis (7).

  When the second cabinet (4) is further pressed toward the butting surface (33) of the first cabinet (3), the projections (6) and (6) of the second cabinet (4) are rail grooves (5) and (5). Are guided by the connecting groove portions (52) and (52), and obliquely slid.

In the oblique sliding movement, the second cabinet (4) approaches the sliding contact surface (32) of the first cabinet (3), and the projections (6) and (6) are formed in the rail grooves (5) and (5) as shown in FIG. The connecting groove portions (52) and (52) slide to the end. As a result, the second cabinet (4) is in sliding contact with the sliding contact surface (32) of the first cabinet (3).
In this process, of the two engagement hooks 41 and 41 shown in FIG. 4, the front engagement hook 41 is placed between the two engagement receiving hooks 31 and 31 shown in FIG. Will intervene.

  When the second cabinet (4) is further pressed toward the butting surface (33) of the first cabinet (3), the projections (6) and (6) of the second cabinet (4) are rail grooves (5) and (5). The second groove portions (53) and (53) are guided to perform a second linear slide movement.

  In the second linear slide movement, the second cabinet (4) moves on the straight line toward the abutting surface (33) while being in sliding contact with the sliding contact surface (32) of the first cabinet (3). As shown, the protrusions (6) and (6) slide until just before the end of the second grooves (53) and (53) of the rail grooves (5) and (5).

When the protrusions (6) and (6) reach just before the end of the second grooves (53) and (53) of the rail grooves (5) and (5), the second cabinet (4) comes into contact with the sliding surface of the first cabinet (3). The first cabinet (3) and the second cabinet (4) are abutted against each other by abutting against the abutting surface (33) while being in sliding contact with (32).
Also, the two engagement hooks 41 and 41 shown in FIG. 4 are engaged with the two engagement receiving hooks 31 and 31 shown in FIG. 6, respectively, thereby the first cabinet 3 and the first hook. The two cabinets (4) are firmly connected to each other.
When the engagement hooks (41) (41) are engaged with the engagement receiving hooks (31) (31), the second groove portions (53) (53) of the rail grooves (5) (5) are provided. Since the projections 6 and 6 are engaged with each other, the coupling force between the first cabinet 3 and the second cabinet 4 is further increased.

According to the video camera, the second cabinet (4) is slid while being guided by the first grooves (51) and (51) of the rail grooves (5) and (5) during the assembly process. Since the position and shape of the first grooves (51) and (51) are defined so that (4) does not interfere with the parts on the chassis (7), interference with the parts on the chassis (7) is surely avoided. I can do it.
Therefore, the restrictions on the arrangement of parts for avoiding the interference between the parts on the chassis (7) and the second cabinet (4) are greatly relaxed compared with the prior art.

Compared with the conventional video camera shown in FIG. 9, the sliding area (the length of the sliding surface (32)) with the first cabinet (3) in the process of sliding the second cabinet (4) is small. As a result, the second cabinet (4) can be smoothly assembled to the chassis (7), and the sliding contact area is reduced, so that the first cabinet (3) and the second cabinet (4) can be assembled. Damage caused by sliding contact with each other can be suppressed.
Furthermore, the engagement hooks 41 and 41 of the second cabinet 4 can be replaced with the engagement receiving hook 31 of the first cabinet 3 only by pressing and sliding the second cabinet 4. ) (31) can be reliably engaged, and assembly work is easy.

In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim. For example, the shape of the rail groove (5) is not limited to the Z-shape or S-shape composed of the first groove portion (51), the connecting groove portion (52), and the second groove portion (53), and the second cabinet (4) is a chassis. (7) Various shapes can be adopted as long as they can be guided to the abutting surface (33) of the first cabinet (3) without interfering with the above components.
The first cabinet (3) and the second cabinet (4) are not limited to aluminum but may be made of other metals such as magnesium, titanium, stainless steel, or synthetic resin.

Also, the second grooves 53, 53 of the rail grooves 5, 5 are slid onto the first cabinet 3 in the latter half of the process of guiding the second cabinet 4. It may be in sliding contact with the contact surface (32).
Furthermore, the guide mechanism for guiding the slide of the second cabinet (4) is not limited to the engagement structure between the rail groove (5) and the protrusion (6), and various known guide mechanisms can be employed. .
