≪顯示裝置1≫ 圖1係本實施方式的顯示裝置1的正視圖。圖2係本實施方式的顯示裝置1的右側視圖。圖3係本實施方式的顯示裝置1的後視圖。圖4係本實施方式的顯示裝置1的立體圖。 顯示裝置1係所謂面板安裝式的可程式顯示器。顯示裝置1被安裝於控制盤的前表面門等的板狀部件。該板狀部件具有開口。並且，顯示裝置1自前側插入板狀部件的開口，並且自後側被固定。顯示裝置1具有作為用於進行測定結果、機器的狀態等的顯示的輸出裝置以及用於輸入設定、操作的輸入裝置的功能。 顯示裝置1包括框部10、主體部20、以及附屬部30。 ＜框部10＞ 框部10在內部具有顯示畫面10a。即，框部10以包覆顯示畫面10a的周圍的方式設置。並且，顯示畫面10a用於進行顯示。另外，顯示畫面10a作為觸屏進行輸入。框部10是具有前表面10F、背面10B、側面10S1、10S2、10S3以及10S4的板狀的部件。在框部10的前表面10F具有顯示畫面10a。另外，在顯示畫面10a的周圍具有邊框部10b。 自正面觀察，側面10S1、10S2、10S3以及10S4相對於框部10的中心分別位於右側、上側、左側以及下側。 顯示畫面10a用於進行圖像、文字等的顯示。另外，操作者自顯示畫面10a進行設定、輸入。邊框部10b配置於顯示畫面10a的周圍。邊框部10b為了保護顯示畫面10a而設置。 與供顯示裝置1安裝的板狀部件具有的開口(例如，後述板狀部件100的開口100H)相比，框部10在正視中變寬。 ＜主體部20＞ 主體部20內置用於使顯示裝置1動作的基板等。主體部20安裝於框部10的背面10B。主體部20為長方體狀。主體部20在正視中比框部10小。即，主體部20與顯示裝置1被安裝的板狀部件所具有的開口(例如，後述板狀部件100的開口100H)相比，在正視中變窄。主體部20具有側面20S1、20S2、20S3以及20S4。另外，主體部20具有背面20B。 自正面觀察，側面20S1、20S2、20S3以及20S4相對於主體部20的中心分別位於右側、上側、左側以及下側。 自正面觀察，側面20S1與框部10的側面10S1相比位於左側。側面20S1具有配件卡合孔21a。在將顯示裝置1安裝於板狀部件100時(參照圖17)，配件卡合孔21a與安裝配件60a卡合。 自正面觀察，側面20S2與框部10的側面10S2相比位於下側。側面20S2具有配件卡合孔21b、21c以及21d。在將顯示裝置1安裝於板狀部件100時(參照圖17)，配件卡合孔21b、21c以及21d分別與安裝配件60b、60c以及60d卡合。 自正面觀察，側面20S3與框部10的側面10S3相比位於右側。側面20S3具有配件卡合孔21e。在將顯示裝置1安裝於板狀部件100時(參照圖17)，配件卡合孔21e與安裝配件60e卡合。 自正面觀察，側面20S4與框部10的側面10S4相比位於上側。側面20S4具有配件卡合孔21f、21g以及21h。在將顯示裝置1安裝於板狀部件100時(參照圖17)，配件卡合孔21f、21g以及21h分別與安裝配件60f、60g以及60h卡合。 背面20B包括固定落下防止部41、固定落下防止部42以及可動落下防止部50。 固定落下防止部41以及固定落下防止部42在背面20B的下側的端部以自側面20S4向下側突出的方式設置(參照圖3)。即，固定落下防止部41以及固定落下防止部42設於主體部20的與顯示畫面10a相反側。 對可動落下防止部50進行說明。圖5係將本實施方式的顯示裝置1的可動落下防止部50附近放大的後視圖。圖6係本實施方式的顯示裝置1的可動落下防止部50附近的剖視圖。具體而言，圖6係圖5的I-I剖視圖。圖7係本實施方式的顯示裝置1的可動落下防止部50的分解立體圖。 可動落下防止部50是板狀的部件。可動落下防止部50例如由聚醯胺等的樹脂形成。可動落下防止部50安裝於主體部20的背面20B。可動落下防止部50以能夠以軸AX1為中心轉動的方式進行安裝，換言之，可動落下防止部50以能夠在圓周方向移動的方式進行安裝。 主體部20包括形成背面20B的背面板22、以及形成側面20S1、20S2、20S3和20S4的框部件23。 可動落下防止部50以能夠以軸AX1為中心在圓周方向移動的方式，隔著圓筒部件51且藉由螺釘52安裝於背面板22。即，可動落下防止部50設於與顯示畫面10a相反側。藉由隔著圓筒部件51安裝於背面板22，可動落下防止部50在自重作用下能夠以軸AX1為中心在圓周方向移動。 主體部20以可動落下防止部50不轉動至規定的角度範圍之外的方式，在背面板22具有移動限制部22a以及移動限制部22b。移動限制部22a防止可動落下防止部50自與X軸方向平行的方向向-Y側轉動。另外，移動限制部22b防止可動落下防止部50自與平行於Y軸相比靠+X側的位置向-X側轉動。 ＜附屬部30＞ 附屬部30內置用於使顯示裝置1動作的基板等。附屬部30特別是內置用於與外部機器連接的接口、電源裝置。附屬部30為長方體狀。附屬部30安裝於主體部20的背面20B。附屬部30在正視中比主體部20小。 ＜顯示裝置1向板狀部件100的安裝＞ 圖8至圖18係用於說明本實施方式的顯示裝置1向板狀部件100的安裝的圖。板狀部件100例如為控制盤的前表面門等。板狀部件100具有前表面100F以及背面100B。另外，板狀部件100具有開口100H。 顯示裝置1藉由自板狀部件100的前表面100F側插入主體部20，從而被安裝於板狀部件100。 開口100H以能夠將顯示裝置1的主體部20插入開口100H的方式，在正視中，形成為比主體部20大約數mm。另外，開口100H以框部10不能穿過開口100H的方式，在正視中，形成為比框部10小。 需要說明的是，板狀部件100的大小不限於圖8至圖18所示大小。板狀部件100只要具有用於安裝顯示裝置1的開口100H即可，其大小可以任意決定。 另外，圖8至圖18中，設定為重力在Y軸方向的-Y朝向起作用。即，設定為板狀部件100相對於地面垂直設置。 如圖8以及圖9所示，顯示裝置1相對於板狀部件100向前面傾斜。並且，向前面傾斜的顯示裝置1在傾斜的狀態下，自顯示裝置1的下側，沿著箭頭A1以及箭頭A2，插入板狀部件100的開口100H。 若顯示裝置1的下側被插入，則在開口100H的下部100H1，固定落下防止部41以及固定落下防止部42與板狀部件100接觸。因此，能夠防止被插入開口100H的顯示裝置1的下側自開口100H向前側脫離。 接下來，在顯示裝置1的下側被插入的狀態下，顯示裝置1的上側被插入開口100H。圖10係顯示裝置1的下側被插入的狀態的顯示裝置1的上側被插入開口100H前的狀態的圖。另外，圖11係將圖10的B的部分放大的圖。圖12示出了在將可動落下防止部50沿箭頭A3轉動的狀態下，將顯示裝置1的上側插入的狀態。 另外，圖13示出了將可動落下防止部50沿箭頭A3轉動的狀態。圖14示出了可動落下防止部50在自重作用下向與箭頭A3相反朝向轉動的狀態。 在顯示裝置1的下側被插入的狀態的顯示裝置1的上側被插入開口100H的情況下，可動落下防止部50與板狀部件100的前表面100F接觸。由於可動落下防止部50與板狀部件100的前表面100F接觸，因此在該狀態下顯示裝置1的上側不能插入開口100H。 於是，使可動落下防止部50沿箭頭A3轉動。若使可動落下防止部50沿箭頭A3轉動，則如圖12以及圖13所示，可動落下防止部50變得能夠通過開口100H，從而顯示裝置1的上側能夠插入開口100H。即，若使可動落下防止部50沿箭頭A3轉動，則可動落下防止部50位於開口100H的內側。可動落下防止部50位於開口100H的內側時的可動落下防止部50的位置為第一位置的一個例子。 而且，在顯示裝置1的上側被插入的狀態下，可動落下防止部50在自重作用下向與箭頭A3相反朝向轉動。如圖14所示，若可動落下防止部50向與箭頭A3相反朝向轉動，則可動落下防止部50與板狀部件100的背面100B接觸。若可動落下防止部50與板狀部件100的背面100B接觸，則顯示裝置1的上側不能自開口100H脫離。即，若使可動落下防止部50向與箭頭A3相反朝向轉動，則可動落下防止部50的一部份位於開口100H的外側。可動落下防止部50的一部分位於開口100H的外側時的可動落下防止部50的位置為第二位置的一個例子。 顯示裝置1的可動落下防止部50被安裝為能夠在第一位置和第二位置之間移動。另外，顯示裝置1的移動限制部22a防止位於第二位置的可動落下防止部50自第二位置向與向第一位置移動的朝向相反的朝向移動。顯示裝置1的移動限制部22b防止位於第一位置的可動落下防止部50自第一位置向與向第二位置移動的朝向相反的朝向移動。 圖15以及圖16示出了顯示裝置1被插入板狀部件100的開口100H的狀態。在顯示裝置1被插入板狀部件100的開口100H的狀態下，顯示裝置1的固定落下防止部41、固定落下防止部42以及可動落下防止部50與板狀部件100的背面100B接觸。藉由顯示裝置1的固定落下防止部41、固定落下防止部42以及可動落下防止部50與板狀部件100的背面100B接觸，能夠防止顯示裝置1自開口100H落下。 由此，本實施方式的顯示裝置1包括固定落下防止部41、固定落下防止部42以及可動落下防止部50，從而能夠在插入板狀部件100的開口100H的狀態下防止顯示裝置1落下。 圖17以及圖18是對最終將顯示裝置1安裝於板狀部件100的方法進行說明的圖。 顯示裝置1使安裝配件60a、60b、60c、60d、60f、60g以及60h分別與配件卡合孔21a、21b、21c、21d、21f、21g以及21h卡合。並且，在卡合的狀態下，藉由擰緊配件卡合孔21a、21b、21c、21d、21f、21g以及21h的螺釘，框部10的背面10B和各個安裝配件60a、60b、60c、60d、60f、60g以及60h包夾板狀部件100。藉由框部10的背面10B和各個安裝配件60a、60b、60c、60d、60f、60g以及60h包夾板狀部件100，從而顯示裝置1被安裝於板狀部件100。 ＜顯示裝置1自板狀部件100的取下＞ 圖19是對於將臨時設置狀態的本實施方式的顯示裝置1自板狀部件100取下的方法進行說明的圖。 臨時設置狀態的顯示裝置1由圖19的P所示的三點進行支承。因此，在將臨時設置狀態的顯示裝置1自板狀部件100取下的情況下，藉由向自正面觀察未被支承的左斜上(沿箭頭A4)拉顯示裝置1，從而能夠將其取下。 另外，可動落下防止部50例如由聚醯胺等的比較柔軟的樹脂形成。因此，在將臨時設置狀態的顯示裝置1自板狀部件100取下的情況下，藉由沿箭頭A5用力拉顯示裝置1的上側亦能夠將其取下。 需要說明的是，在能夠自板狀部件100的背面100B側操作可動落下防止部50的情況下，藉由使可動落下防止部50轉動，從而能夠將臨時設置狀態的顯示裝置1取下。 ＜顯示裝置1的設置方向＞ 圖20是用於說明本實施方式的顯示裝置1向板狀部件110的安裝的圖。板狀部件110具有前表面110F以及背面110B。 可以將顯示裝置1設定為縱式而安裝於板狀部件110。顯示裝置1自前表面110F側插入開口，自背面110B被固定。以能夠將顯示裝置1設定為縱式的方式，以縱向(Y軸方向)成為長度方向的方式形成板狀部件110的開口。 在將顯示裝置1設定為縱式的情況下，例如，將可動落下防止部50設定在下部。並且，將固定落下防止部41以及固定落下防止部42設定為橫向。 如此，本實施方式的顯示裝置1能夠作為縱式的顯示裝置設置於板狀部件110。 ＜作用．效果＞ 本實施方式的顯示裝置包括落下防止部，從而能夠防止顯示裝置滑落。特別是，如本實施方式的顯示裝置那樣，在厚度較薄的情況下，能夠防止顯示裝置滑落。 ＜變形例＞ 雖然本實施方式的顯示裝置1包括固定落下防止部41以及固定落下防止部42，但是例如在顯示裝置1於顯示裝置1的下側不因自重而移動的情況下，可以不設置固定落下防止部41以及固定落下防止部42。藉由包括可動落下防止部50，能夠防止顯示裝置1向前轉動而落下。 板狀部件不限於相對於地面垂直設置的情況。即，板狀部件可以向前面側或相反側傾斜。例如，即使向前面側傾斜，本實施方式的顯示裝置1藉由包括固定落下防止部41、固定落下防止部42以及可動落下防止部50，亦能夠防止顯示裝置1向前面側落下。 需要說明的是，在板狀部件向前面側傾斜的情況下，若板狀部件向前面側傾斜的角度變大，則存在可動落下防止部50不因自重而轉動的情況，因此優選板狀部件相對於垂直為60度以下的傾斜。更優選板狀部件相對於垂直為30度以下的傾斜。 可動落下防止部50不限於因自重轉動。例如，可以以繞軸AX1轉動的方式，具備彈簧等的施力部件、橡膠等的彈性部件等的按壓部件。 需要說明的是，應認為本發明的實施方式的全部的點為例示，並不進行限制。上述實施方式可以不超出附加的申請專利範圍及其主旨地以各種方式進行省略、置換、變更。 Hereinafter, various embodiments of the present invention will be described with reference to the drawings.

The plate member 100 is, for example, a front door of a control panel or the like. The plate member 100 has a front surface 100F and a back surface 100B. In addition, the plate member 100 has an opening 100H. The display device 1 is attached to the plate member 100 by being inserted into the main body portion 20 from the front surface 100F side of the plate member 100 . The opening 100H is formed to be several mm larger than the main body 20 in a front view so that the main body 20 of the display device 1 can be inserted into the opening 100H. In addition, the opening 100H is formed smaller than the frame portion 10 in a front view so that the frame portion 10 cannot pass through the opening 100H. It should be noted that the size of the plate-like component 100 is not limited to the size shown in FIGS. 8 to 18 . The size of the plate member 100 can be determined arbitrarily as long as it has an opening 100H for mounting the display device 1 . In addition, in FIGS. 8 to 18 , it is assumed that gravity acts in the -Y direction in the Y-axis direction. That is, it is set so that the plate-like member 100 is vertically installed with respect to the ground. As shown in FIGS. 8 and 9 , the display device 1 is tilted forward with respect to the plate member 100 . Then, the display device 1 tilted forward is inserted into the opening 100H of the plate member 100 from the lower side of the display device 1 along the arrows A1 and A2 in the tilted state. When the lower side of the display device 1 is inserted, the fixed drop prevention part 41 and the fixed drop prevention part 42 come into contact with the plate member 100 at the lower part 100H1 of the opening 100H. Therefore, it is possible to prevent the lower side of the display device 1 inserted into the opening 100H from coming out of the opening 100H to the front side. Next, in a state where the lower side of the display device 1 is inserted, the upper side of the display device 1 is inserted into the opening 100H. FIG. 10 is a diagram showing a state before the upper side of the display device 1 is inserted into the opening 100H in a state where the lower side of the display device 1 is inserted. In addition, FIG. 11 is an enlarged view of part B of FIG. 10 . FIG. 12 shows a state in which the upper side of the display device 1 is inserted in a state where the movable drop preventing portion 50 is rotated along the arrow A3. In addition, FIG. 13 has shown the state which rotated the movable fall prevention part 50 along arrow A3.

When the upper side of the display device 1 with the lower side of the display device 1 inserted is inserted into the opening 100H, the movable drop preventing portion 50 comes into contact with the front surface 100F of the plate member 100 . Since the movable drop preventing portion 50 is in contact with the front surface 100F of the plate member 100 , the upper side of the display device 1 cannot be inserted into the opening 100H in this state. Then, the movable drop prevention part 50 is rotated along the arrow A3. When the movable drop prevention part 50 is rotated along the arrow A3, as shown in FIGS. 12 and 13 , the movable drop prevention part 50 can pass through the opening 100H, and the upper side of the display device 1 can be inserted into the opening 100H. That is, when the movable fall prevention part 50 is rotated along arrow A3, the movable fall prevention part 50 will be located in the inside of the opening 100H. The position of the movable fall prevention part 50 when the movable fall prevention part 50 is located inside the opening 100H is an example of a 1st position. Then, in the state where the upper side of the display device 1 is inserted, the movable drop prevention part 50 is rotated in the direction opposite to the arrow A3 by its own weight. As shown in FIG. 14 , when the movable fall prevention part 50 turns in the direction opposite to the arrow A3, the movable fall prevention part 50 comes into contact with the back surface 100B of the plate member 100 . If the movable drop preventing portion 50 is in contact with the back surface 100B of the plate member 100 , the upper side of the display device 1 cannot be detached from the opening 100H. That is, when the movable fall prevention part 50 is rotated in the direction opposite to the arrow A3, a part of the movable fall prevention part 50 is positioned outside the opening 100H. The position of the movable fall prevention part 50 when a part of the movable fall prevention part 50 is located outside the opening 100H is an example of a 2nd position. The movable drop preventing portion 50 of the display device 1 is installed so as to be movable between a first position and a second position. Moreover, the movement restricting part 22a of the display device 1 prevents the movable fall prevention part 50 located in the 2nd position from moving in the direction opposite to the direction which moved to the 1st position from a 2nd position. The movement restricting part 22b of the display device 1 prevents the movable fall preventing part 50 located at the first position from moving from the first position in a direction opposite to the direction in which it moves to the second position. 15 and 16 show a state where the display device 1 is inserted into the opening 100H of the plate member 100 . When the display device 1 is inserted into the opening 100H of the plate member 100 , the fixed drop preventing portion 41 , the fixed drop preventing portion 42 , and the movable drop preventing portion 50 of the display device 1 are in contact with the back surface 100B of the plate member 100 . The display device 1 can be prevented from falling through the opening 100H when the fixed drop preventing section 41 , the fixed drop preventing section 42 , and the movable drop preventing section 50 of the display device 1 contact the back surface 100B of the plate member 100 . Thus, the display device 1 according to the present embodiment includes the fixed drop prevention part 41 , the fixed drop prevention part 42 , and the movable drop prevention part 50 , so that the display device 1 can be prevented from falling while being inserted into the opening 100H of the plate member 100 . 17 and 18 are diagrams illustrating a method of finally attaching the display device 1 to the plate member 100 . The display device 1 engages the mounting fittings 60a, 60b, 60c, 60d, 60f, 60g, and 60h with the fitting engaging holes 21a, 21b, 21c, 21d, 21f, 21g, and 21h, respectively. And, in the engaged state, by tightening the screws of the fitting engaging holes 21a, 21b, 21c, 21d, 21f, 21g, and 21h, the rear surface 10B of the frame portion 10 and each of the mounting fittings 60a, 60b, 60c, 60d, 60f, 60g, and 60h sandwich the plate-like member 100 . The display device 1 is mounted on the plate member 100 by sandwiching the plate member 100 between the back surface 10B of the frame portion 10 and the mounting fittings 60a, 60b, 60c, 60d, 60f, 60g, and 60h. <Removal of the display device 1 from the plate member 100> FIG. 19 is a diagram illustrating a method of removing the display device 1 of the present embodiment in a temporarily installed state from the plate member 100 .

Therefore, when the display device 1 in the temporarily installed state is removed from the plate member 100, the display device 1 can be removed by pulling the display device 1 obliquely upward (along arrow A4) to the left where it is not supported when viewed from the front. Down. In addition, the movable drop preventing portion 50 is formed of relatively soft resin such as polyamide, for example. Therefore, when the display device 1 in the temporarily installed state is removed from the plate member 100, it can also be removed by strongly pulling the upper side of the display device 1 along the arrow A5. It should be noted that, when the movable fall prevention unit 50 can be operated from the back surface 100B side of the plate member 100 , the temporarily installed display device 1 can be removed by rotating the movable fall prevention unit 50 . <Installation direction of display device 1> FIG. 20 is a diagram illustrating attachment of the display device 1 to the plate member 110 according to the present embodiment. The plate member 110 has a front surface 110F and a back surface 110B. The display device 1 can be installed in the plate-like member 110 in a vertical configuration. The display device 1 is inserted into the opening from the front surface 110F side, and is fixed from the rear surface 110B. The opening of the plate member 110 is formed such that the vertical direction (Y-axis direction) becomes the longitudinal direction so that the display device 1 can be set vertically. When the display device 1 is set to be vertical, for example, the movable fall prevention part 50 is set in the lower part. Moreover, the fixed fall prevention part 41 and the fixed fall prevention part 42 are set in the horizontal direction. In this way, the display device 1 of the present embodiment can be installed on the plate-shaped member 110 as a vertical display device. <Function.
