And are attached to each other via bolts 9 as fixtures on the other end side (rear side) of the facing surfaces 51A and 61A. The bolt 9 is inserted into the bolt hole 92 formed in the first mounting portion 61 of the second panel component 212 and screwed into the bolt hole 91 formed in the first mounting portion 51 of the first panel component 211. Combined.
The first mounting portion 51 of the first panel component 211 has a taper that increases in thickness from one end to the other end in the vicinity of the bolt 9 on the facing surface 51A (from left to right in FIG. 3B). It is set as the surface 51B.
The opposing surface 61A of the first mounting portion 61 of the second panel component 212 is a flat surface substantially parallel to the lower end surface of the wall portion 212B. Therefore, as shown in FIG. 4, when the bolt 9 is screwed into the first mounting portions 51 and 61, the first mounting portion 61 of the first panel component 211 is formed in the first mounting portion 61 of the second panel component 212. Therefore, the second panel component 212 comes close to the first panel component 211 on the front side of the panel body 21 (see the imaginary line).

Since the tapered surface 51B is increased, the opposing surfaces 51A and 61A of the second panel component 212 and the first panel component 211 are joined from the other end side to the one end side by joining the two parts with a fixture. The second panel component 212 is close to the first panel while the wall 212B is always urged in a direction in which the gap between the wall 212B and the wall 211B of the first panel component 211 is reduced. Fixed to the component 211. Therefore, even if there is a manufacturing error in the first panel component 211 or the second panel component 212, there is no gap between the wall portions 211B and 212B of both components, so that the appearance of the electronic device is improved. can do.

(2) Since the attachment tool is the bolt 9, when the first panel component 211 and the second panel component 212 are joined, it is only necessary to screw the bolt 9, so that the joining operation can be facilitated.

(3) The folded portion 51C is formed in the first panel component 212, and the folded portion 51C is continuous with the guide surface 51D formed substantially parallel to the planar facing surface 61A and the guide surface 51D.

As a result, the two parts can be easily engaged.

(4) Since the second mounting portions 52 and 62 of the first panel component 211 and the second panel component 212 are configured to be concavo-convexly fitted to each other, By pressing the panel component 212 in a plane parallel to the guide surface 51D, the second mounting portions 52 and 62 are fitted to each other so that the engagement between the two components is facilitated. be able to.

(5) A guide projection 53 is provided between the first mounting portion 51 and the second mounting portion 52 of the first panel component 211, and the first mounting portion 61 and the second mounting portion 61 of the second panel component 212. Since the guide groove 63 for guiding the guide projection 53 is formed between the second mounting portion 62 and the second panel component 212, the guide groove 63 is guided to the first panel component 212. Positioning can be performed by the groove 63 and the guide projection 53. Therefore, the first panel component 211 and the second panel component 212 can be smoothly assembled.

(6) A panel 2 is provided on the device main body 1 provided with a plurality of terminals 3A to 3E projecting, and the panel 2 is formed with insertion holes 221A to 221E through which the terminals 3A to 3E are inserted and locked to the device main body 1.

The vicinity of the terminals 3A to 3E of the device main body 1 is directly positioned and covered with the cover 22 that can be reduced in size and thickness, and then the entire device main body 1 including the cover 22 is covered with the panel main body 21. As compared with the conventional case where the entire panel is positioned in order to insert the terminals 3A to 3E into the insertion holes 221A to 221E, the attaching operation can be easily performed. In addition, since the cover 22 and the device main body 1 can be easily positioned, the gap between the terminals 3A to 3E and the holes 221A to 221E can be reduced, so that the device main body 1 can be exposed from this gap. Since there are few, the external appearance of an electronic device can be made favorable.

(7) Since the cover 22 includes the protrusion 221F for preventing electrostatic jumping protruding toward the panel body 21, it is possible to prevent static electricity from entering the inside from the outside of the apparatus.

(8) A plurality of terminals 3A to 3E are arranged in a straight line, the window portion 7 is formed in a substantially oval shape whose longitudinal direction is along the terminal arrangement direction, and the positioning projection 221F is a peripheral edge in the longitudinal direction of the window portion 7 Since the terminals 3 </ b> A to 3 </ b> E are aligned with the longitudinal direction of the window portion 7, the appearance of the electronic device can be improved from this point.

(9) The device body 1 includes a box member 12 that covers the base end portions of the terminals 3A to 3E and has a cover 22 attached to the front surface. The cover 22 is bent from the cover body 221 facing the front surface and the cover body 221. And a locking piece 222 having a locking claw 222A formed at the tip. The box member 12 is formed with an opening 12A for guiding the locking piece 222 and a locking window 12B for locking the locking claw 222A. for that reason,
