As shown in FIG. 1, this digital mixer (electronic device) has a main body 1 that is in an inverted long rectangular pyramid shape and is inclined so that the panel on the upper surface 11 is lowered toward the operator. The upper surface 11 is provided with various operators 111 for processing acoustic signals. Further, an insertion port 121 (see FIG. 2) is formed in the front end surface 12 of the main body 1, and a CD-RW drive (expansion device) 2 can be inserted from this insertion port. The inserted CD-RW drive 2 is stored in the mounting portion 3 in the main body 1 and is electrically connected to the main body 1 as will be described later. Further, a notch portion 21 is provided at the rear end portion of the CD-RW drive 2, whereby the width of the rear end portion is shortened so that it can be easily inserted into the insertion slot 121. In the digital mixer shown in FIG. 1, before fitting the lower case C2 to the upper case C1 and fixing with the rear screw N, side plates (not shown) are previously attached to the left and right ends of the upper case C1 with screws (not shown). The lower case C2 is fitted and fixed in that state.
[0014]
As shown in FIG. 2, the front end face (end face) 12 of the main body 1 is inclined so as to extend outward from the bottom face side 13 toward the upper face side 11. An insertion port 121 is formed in the front. As will be described later, the CD-RW drive 2 is mounted in a state where the front end portion protrudes from the front end surface 12 of the main body, and a cover member 4 surrounding the protruding portion is detachably attached to the front end surface 12 of the main body. . However, the protruding portion of the CD-RW drive 2 is positioned inward of the main body 1 from the upper end edge 14 of the main body front end surface 12.
[0015]
The cover member 4 is formed in an L-shaped cross section including a horizontal portion 41 extending in parallel with the bottom surface 13 of the main body 1 and a vertical portion 42 extending vertically from one end of the horizontal portion 41. The other end of the horizontal portion 41 is fixed to the bottom surface 13 of the main body 1 by a screw 43. Further, an opening 44 into which the CD-RW drive 2 is inserted is formed in the vertical portion 42. The opening 44 is formed to have a size that allows the CD-RW drive 2 to be inserted with almost no gap. By inserting the CD-RW drive 2 along the opening 44, the CD-RW drive 2 can be inserted into the main body 1. It can be guided to the mounting part 3. Further, when the CD-RW drive 2 is mounted at a predetermined position, the front end surface 22 of the CD-RW drive 2 is configured to be substantially flush with the vertical portion 42 of the cover member 4.
[0016]
Further, the cover member 4 includes a cover sheet 45 for closing the opening 44, and a plurality of fixing pins 46 extending from the lower end portion of the vertical portion 42 to the main body 1 side for attaching the cover sheet 45. A plurality of engagement pins 47 extending from the upper end portion of the vertical portion 42 to the main body 1 side are provided. The cover sheet 45 is formed of a flexible rectangular resin sheet, and the lower end portion thereof is fixed to the fixing pin 46 by a heat caulking method such as ultrasonic welding, and the upper end portion is engaged with the above engagement. An engagement hole that engages with the pin 47 is formed.
[0017]
As shown in FIG. 3, a stage 31 is provided inside the main body 1 in the mounting portion 3 to which the CD-RW drive 2 is mounted. The stage 31 is formed of a metal plate in a rectangular shape, and restricts the movement of the CD-RW drive 2 in the width direction, that is, three guide members for guiding the CD-RW drive 2 to a predetermined mounting position. There are provided a horizontal guide member 32, a vertical guide member 33 that regulates the movement in the height direction, and a stopper member 34 that abuts against the CD-RW drive 2 and restricts entry into the interior from a predetermined position. As the stopper member, a later-described connector 341 having a fixed relationship with the stopper member may be substituted. In other words, the rear end of the CD-RW drive 2 may be brought into contact with the connector 341 to serve as a stopper when the CD-RW drive is attached.
[0018]
The lateral guide member 32 is formed by a raised portion in which a part of the stage 31 is cut along the side surface of the CD-RW drive 2 and a part surrounded by the cut is raised. A pair is provided at the front and the rear. Similarly, the vertical guide portion 33 is formed in an L-shape consisting of a vertical surface and a horizontal surface by cutting a part of the stage 31 and raising the portion, bending the portion from the tip, and the horizontal surface is CD. -It is configured to be along the upper surface of the RW drive 2. The stopper member 34 is formed by a plate-like body that is screwed so as to extend vertically from the back end of the stage 31, and a connector 341 is provided on the surface facing the CD-RW drive 2. The connector 341 is connected to the connector 23 of the CD-RW drive 2 when the CD-RW drive 2 comes into contact with the stopper member 34. In the present embodiment, the horizontal guide member 32, the vertical guide member 33, and the stopper member 34 constitute a guide portion of the present invention.
[0019]
As shown in FIG. 2, two screw holes 35 through which fixing screws (fixing means) 5 for fixing the CD-RW drive 2 are inserted are formed in the front and rear portions of the stage 31. The fixing screw 5 is inserted from a concave insertion hole 131 formed in the bottom surface 13 of the main body 1 and screwed into the CD-RW drive 2 through the screw hole 35.
[0020]
Next, installation and removal of the CD-RW drive in the digital mixer configured as described above will be described. In a state where the CD-RW drive 2 shown in FIG. 2 is not mounted, the cover sheet 45 of the cover member 4 engages with the engagement pin 47 and covers the opening 44. When the CD-RW drive 2 is inserted into the opening 44 of the cover member 4 from this state, the CD-RW drive 2 is guided to the mounting portion 3 while being guided by the opening 44. At this time, the CD-RW drive 2 is inserted into the mounting portion 3 while its rear end presses the cover sheet 45. As shown in FIG. 4, the cover sheet 45 is released from the engagement with the engagement pin 47 by being pressed by the CD-RW drive 2, and is bent backward with the lower end fixed to the fixed pin 46 as the center. Opening 44 is opened. When the CD-RW drive 2 is removed, the cover sheet 45 returns to its original state, that is, a state in which the upper end is engaged with the engagement pin 47 and closes the opening 44 due to its elasticity.
[0021]
In the mounting portion 3, the CD-RW drive 2 is inserted to a position where it abuts against the stopper member 34 while being guided by the guide members 32 and 33. When abutting against the stopper member 34, the connector 23 of the CD-RW drive 2 and the connector 341 of the stopper member 34 are connected, whereby the CD-RW drive 2 is electrically connected to the digital mixer body 1. Subsequently, the fixing screw 5 is inserted from the insertion hole 131 of the main body bottom surface 13, and the fixing screw 5 is screwed into the CD-RW drive 2 through the screw hole 35 of the stage 31. Thus, the installation of the CD-RW drive 2 is completed.
[0022]
In order to remove the CD-RW drive 2, first, the fixing screw 5 is removed, and then the cover member 4 is removed. The cover member 4 is removed by removing the screw 43 that fixes the horizontal portion 41 and the main body bottom surface 13. When the cover member 4 is removed in this manner, the front end portion of the CD-RW drive 2 appears in a state of protruding from the main body front end surface 12. In this state, if the front end portion of the CD-RW drive 2 is gripped and pulled, it can be easily removed. Thereafter, only the cover member 4 is attached, and another extension device is attached as necessary.
[0023]
As described above, according to the present embodiment, the cover member 4, the guide members 32 and 33, and the stopper member 34 for guiding the CD-RW drive 2 to the mounting portion 3 are provided in the main body 1 of the digital mixer. Therefore, the CD-RW drive 2 can be smoothly inserted, and as a result, the mounting operation can be easily and reliably performed. In particular, since the opening 44 of the cover member 4 is formed to have a size that allows the CD-RW drive 2 to be inserted substantially, there is an advantage that positioning for inserting the CD-RW drive 2 can be performed.
[0024]
Further, when the CD-RW drive 2 is mounted, the front end of the CD-RW drive 2 protrudes from the front end surface 12 of the main body. Therefore, after the cover member 4 is removed, the protruding portion is gripped. The CD-RW drive 2 can be easily removed. Thus, although the front end portion of the CD-RW drive 2 protrudes from the front end surface 12 of the main body, the protruding portion is located inward of the upper end edge 14 of the front end surface 11 of the main body, Damage can be prevented.
[0025]
In addition, by providing the cover member 4 on the outer surface of the main body 1 as described above, a design-like accent can be expressed, thereby providing an advantage of showing a kind of status that the expansion device can be mounted. is there.
[0026]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, the shape of the guide members 32 and 33 shown in the above embodiment is not particularly limited as long as the guide members 32 and 33 can be configured to guide an extension device such as the CD-RW drive 2 to the mounting portion 3.
[0027]
Moreover, in the said embodiment, although the main body front end surface 12 in which the insertion port 121 was formed inclines so that it may extend outward (front) of the main body 1 as it goes from the bottom face 13 to the upper surface 11, this is opposite, ie, You may incline so that it may extend outside the main body 1 as it goes to the bottom face 13 from the upper surface 11. Even with this configuration, the front end portion of the CD-RW drive 2 is inward of the lower end edge of the main body front end surface 12, and therefore, it is prevented from being hit. Further, the insertion port 121 can be provided not only on the front end surface 12 of the main body but also on the side surface of the main body or the back surface.
[0028]
In the above embodiment, the connector 341 is provided on the stopper member 34 so that the electrical connection is made when the CD-RW drive 2 contacts the stopper member 34. For example, as shown in FIG. The electrical connection between the CD-RW drive 2 and the main body 1 may be performed by another cable. FIG. 5 is a cross-sectional view showing another example of the mounting portion. As shown in the figure, in this example, the rear end portion of the stage is raised to form a cut-and-raised portion 36, which is used as a stopper member. Thereby, the backward movement of the CD-RW drive 2 is restricted. The cut-and-raised part 36 is formed in a size that does not cover the connector 23 of the CD-RW drive 2. An opening 132 for connection work is formed in the main body bottom surface 13 behind the cut and raised portion 36, and the main board 15 of the main body 1 is provided further behind the opening 132. The opening 132 is normally covered with a lid 137 and is opened only during work.
[0029]
For the connection work, the flat cable 6 is used. After the CD-RW drive 2 is fixed to the mounting portion 3, the lid 137 is opened and one end of the flat cable 6 is connected to the connector 23 of the CD-RW drive 2. Incidentally, the other end is formed by being connected in advance to a connector (not shown) of the main board 15. A cutout 151 is formed at the end of the main board 15 near the opening 132, so that the flat cable 6 can be easily inserted into the main board 15 inside the main body 1. When the connection is completed, the opening 132 is closed by the lid 137. According to such a configuration, even when an extension device having a different connector shape may be mounted, it can be easily handled by additionally attaching a cable with a suitable terminal to the cable 6 each time.
[0030]
Moreover, in the said embodiment, although the CD-RW drive 2 is fixed using the fixing screw 5 as a fixing means, the fixing means of this invention is not limited to this. For example, the CD-RW drive 2 is automatically locked to the CD-RW drive when the CD-RW drive 2 is disposed in the mounting portion 3, and a locking piece that can be released when the lever outside the main body is operated is provided. This method can also be realized.
[0031]
In the above-described embodiment, an example in which the present invention is applied to a digital mixer has been described. However, the present invention is not limited to this, and can be applied to various electronic devices to which an extension device can be attached. The present invention can also be applied to a notebook type or desktop type personal computer. In addition to the above-described CD-RW drive, the expansion device can be applied to various devices such as an FDD drive, a CD-ROM drive, a DVD drive, and a hard disk.
[0032]

Therefore, the extension device can be inserted smoothly and can be attached easily and reliably.
[0033]
Further, according to the present invention (second invention), since a part of the expansion device is mounted in a state of protruding from the insertion port, the expansion device can be easily removed by gripping and pulling the protruding portion. . As described above, although a part of the extension device protrudes from the insertion port, either one of the end edge on the upper surface side and the bottom surface side of the end surface protrudes outward from the other, and the extension device is more than the end edge on the protrusion side. Since the protruding portion is located inward of the main body, it is possible to prevent the extended device from being damaged by hitting the protruding portion.
[0034]
Further, according to the present invention (third invention), the cover member having the opening is attached so as to surround the insertion port, and the expansion device is passed almost densely so that the opening guides the insertion into the mounting portion. Since it has an opening dimension, the positioning when inserting the expansion device into the insertion port is facilitated, and as a result, the mounting operation of the expansion device becomes easier.
