A card slot 20 is formed, and a memory card cover 90 is movably provided on the side panel 30A to open and close the memory card slot 20.

  The memory card slot 20 formed in the side panel 30A is formed in alignment with the memory card mounting opening 301 formed in the side plate 4A in the insertion / removal direction of the memory card 200.

  In the present embodiment, the memory card 200 moves in the horizontal direction (the direction of arrow C in FIG. 12) and can be attached to the memory card attachment unit 300, that is, can be inserted and removed. On the other hand, the memory card cover 90 moves in the vertical direction (arrow D direction in FIG. 12) perpendicular to the insertion / removal direction (C direction) of the memory card 200 with respect to the memory card mounting opening 301 with respect to the memory card mounting part 300. The card mounting opening 301 is opened and closed.

  Of course, the memory card 200 may be configured to be inserted / removed at a predetermined angle with respect to the horizontal direction. Also in this case, the memory card cover 90 is configured to move in a direction orthogonal to the insertion / removal direction of the memory card 200.

  FIG. 13A shows a state in which the memory card cover 90 is moved downward in the vertical direction (that is, the opening release position) in this embodiment, and the memory card 200 is mounted in the memory card slot 20. An embodiment is shown. FIG. 13B shows a state in which the memory card cover 90 is moved upward (opening closed position), and the memory card 200 attached to the memory card attachment part 300 is applied with a predetermined force into the memory card attachment part. The state of pressing is shown.

  Next, the structure of the memory card cover 90 and the side panel 30A for attaching the memory card cover 90 will be described.

Referring to FIGS. 12 and 16 (a) and 16 (b), the memory card cover 90 includes a cover main body 91 that is a substantially rectangular plate-like member having a width W90, a height H90, and a thickness T90. in the present embodiment and an operation manual stage which is a plate-shaped operating protrusion 92 that protrudes horizontally from the cover body 91 is positioned at the lower end 91a of the cover body 91. The protrusion 92 functions as a knob (operation piece) for moving the cover 90 up and down. The width W91 of the protrusion 92 is made smaller than the width W90 of the cover main body 91, and both horizontal end portions 91c of the cover main body 91 have support portions for the guide grooves 43 formed in the side panel 30A, as will be described in detail later. Form. Further, guide ribs 93 are formed on both end portions 91c of the cover main body 91 so as to abut against the inner side of the guide groove 43 and suppress backlash during movement.

  In the present embodiment, the cover main body 91 is described as having a rectangular shape. However, the cover main body 91 does not have to be rectangular. For example, the upper end edge 91b and / or the lower end edge 91a is not a straight line, but is a mountain shape. Alternatively, it may be polygonal, or arcuate.

  Referring to FIGS. 14, 15A, and 15B, the side panel 30A extends from the upper side by a predetermined length L43 with a gap width G43 and a lateral width W43 with respect to the side plate 81 from the upper end. The formed space is formed. As a result, when the side panel 30A is mounted on the measuring instrument main body 2, the inner wall member 41 is formed on the side facing the measuring instrument main body 2, and the inner wall member 41 is spaced from the measuring instrument main body 2 on the opposite side. The outer wall member 42 is formed separated by a width G43.

  A memory card slot 20 is formed in the inner wall member 41. As described above, the memory card slot 20 is formed so as to align with the memory card mounting opening 301 formed in the side plate 4A in the insertion / removal direction of the memory card when the side panel 30A is mounted on the measuring device main body 2. .

  In addition, the outer wall member 42 is wider than the width W91 of the operation projection 92 but narrower than the width W90 of the cover body 91 so that the projection 92 of the memory card cover 90 can move in the vertical direction. An opening 44 of W44 is formed.

  Therefore, a guide groove 43 is formed between the inner wall member 41 and the outer wall member 42 to hold the memory card cover 90 that is a plate-like member by the cooperation of both members 41 and 42 and to guide it in the vertical direction. Is done.

  As shown in FIG. 15B, the side plate 81 of the side panel 30 </ b> A is above the upper end surface 41 a located above the memory card slot 20 of the inner wall member 41 by a predetermined distance and opposite to the memory card slot 20. This region is also excised to form a space V1. Further, the upper end 44a of the opening 44 of the outer wall member 42 (that is, the end edge 42a of the outer wall member 42) is located above the upper end surface 41a of the inner wall member 41 by a distance H43, and therefore the inner surface of the side panel 30A. When viewed from the side, a space V2 having a width W43 and a height H43 is formed above the inner wall member 41.

  Next, a method for assembling the memory card cover 90 on the side panel 30A configured as described above will be described with reference to FIGS.

  First, as shown in FIGS. 16A and 16B, and FIGS. 17A and 17B, for the side panel 30A in a single component state before being mounted on the measuring instrument main body 2, The memory card cover 90 is arranged so that the protrusion 92 of the memory card cover 90 is positioned on the side of the inner wall member 41 of the side panel 30A (FIG. 16A). Next, the memory card cover 90 is fitted from the side of the inner wall member 41 of the side panel 30 </ b> A to the space V <b> 1 formed on the upper end surface 41 a of the inner wall member 41. At this time, the protrusion 92 of the memory card cover 90 passes through a space V2 (FIG. 15) formed by the upper end surface 41a of the inner wall member 41 and the upper end edge 44a of the opening 44 of the outer wall member 42. Will enter.

  That is, the protrusion 92 is formed on the side plate 81 of the side panel 30A with the memory card cover 90 held vertically between the upper end edge 44a of the outer wall member 42 and the upper end surface 41a of the inner wall member. Spaces V1 and V2 that can be inserted through are formed. Accordingly, as shown in FIGS. 17A and 17B, before the side panel 30A is attached to the measuring instrument main body 2, the memory card cover 90 is attached to the outer wall member from the side facing the measuring instrument main body 2 of the side panel 30A. Next, as shown in FIG. 17B, the projection 92 of the memory card cover 90 is pressed between the opening upper edge 44a of the outer wall member 42 and the inner wall member upper end surface 41a. And is inserted into the opening 44 through the space V2 formed in FIG. As a result, the lower ends of both side portions 91 of the memory card cover 90 are arranged at the position of the upper insertion opening end 43 a of the guide groove 43. Next, the memory card cover 90 is moved downward, and the both side holding portions 91 c of the memory card cover 90 are arranged in the guide groove 43. The guide rib 93 (FIG. 16B) formed on the both side holding portions 91c of the memory card cover 90 is slidably brought into contact with the inner groove wall surface of the guide groove 43, so that the memory card cover 90 has an appropriate frictional force. Thus, it can be moved up and down without rattling.

  Next, in the side panel 30A in which the memory card cover 90 is incorporated, the side panel lower mounting portion 83 is first placed in the protector 3A, as shown in FIG. 18A, as described above with reference to FIG. The side panel upper mounting portion 82 is maintained in an inclined state spaced from the protector 3A. Next, as shown by the arrow A, the side panel 30A is pushed down obliquely, and the concave groove 88 (that is, the projecting pieces 86 and 87) of the side panel lower mounting portion 83 is measured as shown in FIG. The outer edge flange 54 of the device body 2 and the rib 72 of the protector 3A are mounted so as to be sandwiched therebetween. Next, as shown by the arrow B, the upper side of the side panel 30A is pressed toward the protector 3A with the side panel lower mounting portion 83 as a fulcrum.

  As a result, as shown in FIG. 12, the rib-shaped protrusion 84 of the side panel 30A engages with the groove 62 of the protector 3A, and the protrusion 63 of the protector 3A is fitted into the concave groove 85 of the side panel 30A. At the same time, the concave groove 88 of the side panel 30A holds the outer edge flange 54 of the measuring instrument main body 2 and the rib 72 of the side panel 30A in a firmly sandwiched state.

  Thus, the side panel 30A is firmly attached to the protector 3A by an extremely simple assembly operation.

  As shown in FIG. 12, when the side panel 30A is attached to the measuring device main body 2, the upper end surface 41a of the inner wall member 41 extends downward from the flange 52 of the measuring device main body 2 and is integrally formed. The first protrusion 52c1 formed on the regulating member 52c comes into contact with the first protrusion 52c1. The regulating member 52c further includes a second protrusion 52c2 that extends to the position of the upper end edge 44a of the opening 44 of the inner wall member 42 toward the inner wall member 42 side of the side panel 30A. It abuts on the upper end edge 91b of the memory card cover 90 that has moved upward, and functions as a member that regulates further upward movement (jumping out) of the cover 90. Therefore, the memory card cover 90 does not fall off from the side panel 30A.

  The memory card cover 90 assembled in this manner is slidably held on the side panel 30A and moves in a direction perpendicular to the insertion / removal direction of the memory card 200 with respect to the memory card mounting opening 301 with respect to the memory card mounting portion 300. Thus, the memory card mounting opening 301 can be opened and closed. Therefore, even if the protector 3 is provided, the cover 90 will not open even if a vibration or impact is applied in the direction in which the memory card 200 is removed. Thereby, an electronic device with extremely high reliability can be provided.

  Further, according to the present embodiment, as shown in FIG. 13A, the holding projection 45 that contacts the memory card cover 90 is formed on the side surface of the inner wall member 41 that faces the memory card cover 90. In this embodiment, there are a total of three protrusions, one above the memory card slot 20, one at the center of the lateral length of the slot 20, one below the slot 20 and one near each end of the slot 20. 45 is formed.

  Accordingly, as shown in FIG. 16A, the memory card cover 90 moves upward on the side surface corresponding to the inner wall member 41 of the memory card cover 90 in correspondence with the holding projection 45, and the closed position. Two concave portions 94 are formed on the upper side and two on the lower side so as to be fitted to the holding projection 45 when positioned in the position. Guide grooves 95 are formed so as to be aligned in the vertical direction with respect to the respective recesses 94. Accordingly, the guide groove 95 fits into the holding projection 45 when the memory card cover 90 moves upward, guides the memory card cover 90, and the holding projection 45 moves to the upper position when the memory card cover 90 moves to the upper position. 90 will be fitted into the recess 94. Therefore, the memory card cover 90 is restrained and held in the closed position when it is moved upward. On the other hand, the lower position is not restrained. The memory card cover 90 may be constrained at a lower position with a structure such as a taper so that the width of the guide groove 43 or the gap between the guide grooves 43 and 43 is gradually narrowed. Good.

  Further, when the memory card cover 90 moves upward on the surface corresponding to the inner wall member 41 of the memory card cover 90 and moves from the open position to the closed position, the memory mounted in the memory card mounting section 300 is used. In order to slidably contact the rear end surface of the card 200 in the insertion direction and urge the memory card 200 inward of the memory card mounting portion 300, two parallel projecting ribs 96 extending in the vertical direction are formed. Accordingly, when the memory card cover 90 moves upward and moves to the closed position, the projecting rib 96 slidably contacts the rear end surface of the memory card 200 mounted in the memory card mounting unit 300 in the insertion / removal direction. The card 200 is urged into the memory mounting portion.

Example 2
In the first embodiment, the memory card cover 90 is located at the lower end of the cover main body 91 as an operation means, and is provided with a plate-like operation protrusion 92 protruding from the cover main body 91 in the horizontal direction. explained.

  In the present embodiment, as shown in FIG. 19, the operating means is not a projection 92 but a recess 92 a. The operator can slide the memory card cover 90 in the vertical direction by placing a finger or a nail on the recess 92a.

  In this embodiment, as shown in FIG. 20, the memory card cover 90 is formed on one side of the guide groove 43, that is, on the upper side in this embodiment, before the side panel 30A is attached to the device body 2. The both sides of the memory card cover 43 can be fitted into the guide groove 43 from the insertion opening end 43a.

  Of course, as in the first embodiment, as shown in FIG. 17A, the memory card cover 90 is pressed against the back surface of the outer wall member 42 on the inner wall member 41 side from the side facing the measuring device body 2 of the side panel 30A. Then, as shown in FIG. 20, the both side holding portions 91 c of the memory card cover 43 can be fitted into the guide groove 43 from the memory card cover insertion opening end 43 a and attached.

  On the other hand, in the present embodiment, the memory card cover 90 is not provided with the projection 92 as in the first embodiment, and thus is formed between the opening upper edge 44a of the outer wall member 42 and the inner wall member upper end surface 41a. The space V2 is not necessarily required, that is, V2 may not be formed. In some cases, the upper end edge 44a of the opening of the outer wall member 42 may be positioned below the inner wall member upper end surface 41a in FIG.

  According to the electric device with a memory card according to the present invention configured as described in the first and second embodiments, even in the case of the structure having the protector 3, the direction in which the memory card is removed Even if vibration or impact is applied to the cover, the cover will not open. Further, the cover can always push the rear end surface of the memory card in the insertion direction, and the stability and reliability of the card holding state in the static state during normal use can be improved. Furthermore, even in a complicated structure with a protector, it is possible to easily assemble the cover in a single item state for a side panel that is a separate part, and it is easy to assemble the device body together with the protector. . Further, there is an advantage that the cover cannot be removed after the side panel is assembled into the device body.

  In the above-described embodiment, the side panel 30A is described as being attached to the measuring instrument main body via a protector attached to the side surface of the measuring instrument main body 2. However, the side panel 30A is directly attached to the measuring instrument main body 2 without passing through the side panel. The structure attached to a side part may be sufficient. In this case, the side panel may be attached to the measuring device main body 2 with an attaching screw or the like.

  In the above embodiment, the memory card is described as being inserted / removed in the horizontal direction with respect to the memory card mounting portion. However, as described above, the memory card can be inserted / removed from other directions. As described above, the above-described effects can be achieved.
