【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 (a) and 1 (b) are perspective views showing a panel unit mounting structure of the present invention, and FIGS. 2 (a) and 2 (b) are a plan view and a side view of the panel unit 3, respectively. 2 is a partial cross-sectional view of the case constituting the above. The case 3a is composed of upper and lower cases 32 and 33 which are horizontally divided into upper and lower parts. The upper and lower cases 32, 33 have recesses 32a, 33a on one end side of the divided surfaces, which open to the one end surface side. Further, a recess 37 is formed on the other end side of the division surface of the lower case 33 and opens to the other end surface side. When the upper and lower cases 32 and 33 are combined, the recesses 32a and 33a form the engaging piece housing recess 39, and the recess 37 and the dividing surface of the upper case 32 form the engaging recess 38. The engagement piece 34 is accommodated in the engagement piece storage recess 39 so as to be movable in the longitudinal direction of the panel unit 3. The engagement piece 34 is prevented from coming off by engaging both ends of the engagement piece 34 with the protrusions 39a protruding inward from both sides of the opening of the storage recess 39. A compression spring 35 is arranged between the engagement piece 34 and the bottom surface of the storage recess 39 to constantly urge the engagement piece 34 toward the opening side. At this time, the front surface 31 of the engagement piece 34 and one end of the case 3a are substantially flush with each other. A pair of engaging recesses 34a, 34a are formed on the front surface 31 of the engaging piece 34. Further, one end surface of the lower case 33 is provided with a notch 33c which is a notch between the lower edge of the recess 33a and the lower surface of the lower case 33, and the lower end on one end side of the engaging piece 34 is the lower surface of the lower case 33. It is exposed to. Assembling the engagement piece 34 and the spring 35 into the case 3a, the upper and lower cases 32 and 33 are separated, and the engagement piece 34 and the spring 35 are housed in the recess 32a of one case 32, and the other This can be easily performed by combining the cases 33 of. Although not shown, the upper and lower cases 32, 33 are provided with known holding means for holding the combined state of the upper and lower cases 32, 33. In the figure, 3b indicates a switch operating portion and 3c indicates a liquid crystal display element.

On the other hand, the panel surface of the device body 4 has a mounting recess 41 of a size capable of accommodating the panel unit 3 just like the conventional example. A pair of engagement protrusions 44, 44 is provided on the inner surface of the mounting recess 41 on one end side so as to correspond to the engagement recess 34 a of the panel unit 3. The upper surface of the engagement protrusion 44 is an inclined surface. An engaging protrusion 42 is provided on the inner surface of the other side of the mounting recess 41 so as to correspond to the engaging recess 38 of the panel unit 3. Further, a groove 43 opening to the panel surface is formed between the engaging protrusions 44, 44 on the inner surface on one end side of the mounting recess 41. The width dimension of the groove 43 is set so that a fingertip can be inserted, and the bottom surface of the groove 43 is an inclined surface that is continuous from the top surface of the device body 4 to the bottom surface of the mounting recess 41. Next, in order to mount the panel unit 3 in the mounting recess 41 of the device body 4 configured as described above, the end of the panel unit 3 where the engaging recess 38 is provided is attached to the mounting recess 41 of the device body 4. Then, as shown in FIG. 3, the engaging recess 38 is engaged with the engaging protrusion 42 on the device body 4 side. Next, the panel unit 3 is rotated toward the mounting recess 41 side of the device body 4 around the engaging portion between the engaging recess 38 and the engaging protrusion 42. Therefore, as shown in FIG. 4A, the lower end on the front surface side (one end side) of the engaging piece 34 of the panel unit 3 comes into contact with the slope of the engaging protrusion 44 provided in the mounting recess 41.

When the panel unit 3 is pressed from this state, as shown in FIG. 4B, the engagement piece 34 receives the reaction force from the engagement protrusion 44, and resists the elastic force of the spring 35. Slide in one direction. Furthermore, when the panel unit 3 is pushed into the mounting recess 41 and the position of the engaging recess 34a of the engaging piece 34 and the engaging protrusion 44 on the device body 4 side are aligned, as shown in FIG. The return force of 35 returns the engagement piece 34 to the original position, and the engagement recess 34a and the engagement protrusion 44 engage with each other. Therefore, in the panel unit 3, the engagement recess 38 on one end side engages with the engagement protrusion 42 of the device body 4, and the engagement recess 34a of the engagement piece 34 on the other end side engages with the device body 4. By engaging with the protrusion 44 (see FIG. 5), it is securely mounted in the mounting recess 41 of the device body 4. Next, in order to release this engagement state and remove the panel unit 3 from the mounting recess 41 of the device body 4, insert a finger into the groove 43 of the device body 4 and move the engagement piece 34 against the elasticity of the spring 35. Then, by pushing inward, the engagement recess 34a of the engagement piece 34 and the engagement protrusion 44 of the device body 4 are disengaged. Thereafter, the panel unit 3 is rotated upward around the engaging portion between the engaging concave portion 38 and the engaging convex portion 42, and then the engaging concave portion 38 and the engaging convex portion 42 are disengaged. As a result, it is taken out from the mounting recess 41 of the device body 4. In the above embodiment, the coil spring is used as the spring 35 for urging the engaging piece 34, but the spring is not limited to this, and a leaf spring may be used, for example. Further, it may be considered that a magnet is attached to the surfaces of the engagement piece 34 and the inner wall surfaces of the cases 32 and 33 that face each other, and the repulsive force of the magnet is utilized. Further, in the embodiment, the engaging recesses 34a, 38 are provided on the panel unit 3 side, and the engaging protrusions 42, 44 engaging with the engaging recesses 34a, 38 are formed on the device body 4 side. It goes without saying that the engaging protrusion may be provided on the side and the engaging recess may be formed on the device body side.

[Effect of device]

 As described above, the panel unit of the present invention has the engagement recess formed on the end face on one end side and the engagement recess provided on the end face on the other end side in the state of being resiliently urged to the other end side. It is installed so that it can be pushed in freely. As a result, the panel unit engages the engaging recess on the one end side with the engaging protrusion formed on one inner wall surface of the device body mounting recess, and the engaging recess of the engaging piece on the other side of the device body. It is attached to the main body of the equipment by elastically engaging the engaging protrusions on the wall surface. For this reason, the panel unit can be easily attached to and detached from the main body of the device as compared to the operation of attaching and detaching the panel unit with screws as in the conventional example. Moreover, since the elastic force of the engagement piece acts on the engaging portion between the panel unit and the device body, a panel unit mounting structure can be obtained in which the panel unit can be mounted on the device body with increased reliability.
