However, in the above light control cover mounting structure, the latch claw 7a provided on the latch member 7 on the light control cover 2 side is placed laterally with respect to the latch claw insertion hole 4a provided on the hook member 4 on the device main body 1 side. Since the light control cover 2 is inserted and engaged from the side, when the light control cover 2 is pushed from the side when wiping and cleaning the outer surface of the light control cover, etc.
This poses a problem in that there is a danger that the light control cover 2 may fall. This is because when no external force is applied to the light control cover 2, the insect-proof gasket 3 prevents the light control cover 2 from shifting, but when a force is applied to the light control cover 2 in a horizontal direction, the light control cover 2 is prevented from shifting. This is because the cover 2 shifts while bending the insect repellent gasket 3, and when the light control cover 2 shifts in the direction in which the hooking member 4 and the hooking member 7 are opposed to each other, the hooking pawl 7a is hooked. The light control cover 2 will come off from the latch claw insertion hole 4a of the member 4 and fall.

ことができなくなるから、前記掛止爪7aを大き
くして掛止爪挿入孔4aへの掛止爪係合深さを制
光カバー2のずれ動き量よりも深くすることは実
用上問題があつた。 In addition, in order to prevent the light control cover 2 from falling due to the shifting movement of the light control cover 2, the latching claw 7a is enlarged so that the depth of engagement of the latching claw into the latching claw insertion hole 4a is set to the light control cover 2. The depth of engagement of the latch claw with the latch claw insertion hole 4a can be made deeper than the amount of displacement in step 2, but if the depth of engagement of the latch claw with the latch claw insertion hole 4a is increased in this way, when the latch claw 7a is detached from the latch claw insertion hole 4a, As the hooking member 4 rotates, the amount of pushing up of the hooking claw 7a (the amount of pushing up of the light control cover 2) also increases, so that the insect repellent hitting the edge plate 1a of the device body 1 increases. In order to push up the latch claw 7a significantly against the elastic resistance of the seal 3, it is necessary to press the latch release pin 8 with a fairly strong force, which makes it difficult to remove the light control cover 2 with good operability. Therefore, it is practically problematic to enlarge the latch claw 7a so that the depth of engagement of the latch claw with the latch claw insertion hole 4a is deeper than the amount of displacement of the light control cover 2. Ta.

That is, this device has a pair of guide plate portions extending downward on both sides on the lower surface of the instrument main body, and the inner edges of the guide plate portions are inclined downward and outward, respectively, and the guide plate portions are inclined downwardly and outwardly. A spring receiving plate with a spring hook recessed outward is provided almost vertically at the upper end of the inner edge of the plate, and a V-shaped spring is installed on the side of the light control cover to restrict its vertical movement. Then, the distal ends of the pair of spring legs of this V-shaped spring are engaged with the spring hooking portions of the spring receiving plate by the expanding force of the V-shaped spring, and the distal ends of this V-shaped spring are connected to the spring receiving portions of the spring receiving plate. A retaining portion to be hooked on the back side of the plate is formed, and the light control cover is formed into a V shape by sandwiching both spring legs of the V-shaped spring from both sides and pressing an operating member protruding from the outer surface of the light control cover. The device has a spring opening regulating member that moves toward the tip of the spring legs while compressing the spring to separate both spring legs from the spring hooking portion of the spring receiving plate. By pressing the V-shaped spring to the side, the spring leg of the V-shaped spring is guided by the inner edge of the guide plate part of the spring receiving plate and enters the inside of the guide plate part, and the expanding force of the V-shaped spring moves the spring leg into the spring receiver. The V-shaped spring was engaged with the spring hook part of the plate, and the light control cover was supported by the spring receiving plate, and the light control cover was displaced in the direction in which the V-shaped spring approached the spring receiving plate. In this case, the spring leg is expanded by the spring force of the V-shaped spring to prevent the spring leg from coming off from the spring retaining part, and if the light control cover moves in the opposite direction, the retaining part at the end of the spring leg is fixed to the spring retainer. The light control cover is prevented from falling by catching it on the back of the plate and preventing the spring leg from coming off from the spring latching part, and furthermore, by pressing the operation member, the V-shaped spring is controlled by the spring opening regulating member. The light control cover is removed by compressing the spring leg and separating it from the spring hook.
