201206591 作機械組彼此配置成背向貼合。此情況，使另一方的工作 機械組的給材裝置的背面側位在一方的工作機械組的工作 機械的背面側，使另一方的工作機械組的工作機械的背面 側位在一方的工作機械組的給材裝置的背面側。由此，2 組工作機械組彼此成爲點對稱的配置。 但是此配置，是在減小橫方向的佔有空間（橫寬度） 的點的話有效，但是兩工作機械組的各工作機械的背面側 的空間’會被彼此另一方的工作機械組的給材裝置塞住， 而使維修性下降。 在此’如第5圖的平面圖所示，將2組工作機械組的給 材裝置彼此配置成背向貼合。此情況，另一方的工作機械 組的給材裝置的背面側是位在一方的工作機械組的給材裝 置的背面側。由此，使各工作機械的背面側的空間不會被 塞住的方式來防止維修性的下降。 但是由此配置所產生的2組工作機械組，從正面所見 時’一方的工作機械的正面、位於前後的2組給材裝置、 另一方的工作機械的背面，是成爲呈橫方向依序並列的狀 態’而有橫方向的佔有空間變大的問題。 且’橫方向的佔有空間變大的話，在工場等的敷地形 狀等預先被限定的空間內，配置這些工作機械組時，其配 置方向等會有限制，而具有無法有效利用空間的問題。 本發明是鑑於上述狀況，其目的是提供一種工作機械 ，在將2以上的複數個集合配置的狀態下，不會使維修性 下降，並可以減小橫方向的佔有空間。 201206591 (用以解決課題的手段） 爲了達成上述目的，本發明的工作機械，具備將 的加工對象物把持的主軸，將前述加工對象物，在配 前述主軸的加工部進行加工，其特徵爲：藉由被配置 工作機械側方的其他的工作機械被加工的加工對象物 並設收容於前述主軸，並且將前述被收容的加工對象 給至前述其他的工作機械的給材部，是設在前述加工 背面側的領域。 [發明的效果] 依據如此構成的本發明的工作機械，從被一體設 工作機械的加工部的背面側的領域的給材部，朝被配 本發明的工作機械的側方的其他的工作機械，供給加 象物（以下稱爲工件）。由此，不需要在該其他的工 械另外設置給材裝置，不會使本發明的工作機械的維 下降。且，藉由將該其他的工作機械也作成本發明的 機械，就可使橫方向的佔有空間比以往更小。 即，在本發明的工作機械中，收容由其他的工作 被加工的工件並且將該工件朝該其他的工作機械供給 材部，是設於配置有主軸的加工部的背面側的領域。 ，可以將從加工部的背面側的領域被收容於給材部的 供給至其他的工作機械。 即，在本發明的工作機械中，只有將該其他的工 械，配置於本發明的工作機械的側方，本發明的工作 棒狀 置有 於此 ，是 物供 部的 在此 置於 工對 作機 修性 工作 機械 的給 因此 工件 作機 機械 8 - 201206591 的給材部，就可將被並設收容在該主軸的工件，供給至該 其他的工作機械的主軸。因此’在本發明的工作機械中， 不需要在該其他的工作機械另外設置給材裝置。 在此，該其他的工作機械，可適用本發明的工作機械 。在此情況中，2個本發明的工作機械是被並列配置在彼 此的側方。因此，在各本發明的工作機械中，彼此被收容 於其他的工作機械的給材部的工件，是藉由其給材部被供 給。由此，在各工作機械中，不需要另外分別設置對應其 的給材裝置。 因此’如習知隨附於各工作機械設置的給材裝置，不 會塞住另一方的工作機械的維修時所利用的作業領域（例 如背面側空間）和加工時的作業空間（正面側空間）。 又，將2個本發明的工作機械配置於彼此的側方的狀 態中的橫方向的佔有空間，不會超過將2個工作機械的橫 寬度合算的長度的空間。因此，在本發明的工作機械中， 可以比如習知將2個給材裝置彼此背向貼合（背面彼此相 對的狀態）的方式配置的2個工作機械組所佔有的情況， 更減小橫方向的空間。 如此’依據本發明的工作機械，在將2以上的複數個 集合配置的狀態下’不會使維修性下降，可以減小橫方向 的佔有空間。 【實施方式】 第1圖’是顯示本發明的工作機械的一實施例的自動 -9 - 201206591 車床1 00。 此自動車床100，是對於被把持在主軸10的長條的棒 材也就是工件2 0 0 (加工對象物）’進行切削、旋削 '穿 孔等的加工的工作機械。 工件200，是如第1圖（a)的前視圖及第1圖（b)的 平面圖所示，從主軸1 〇的後端側的側方即圖的右側方被供 給並被把持在主軸1 〇，藉由此主軸1 0繞軸旋轉’沿著軸線 朝圖示左方向被送出。 在主軸1 〇的前端（先端）側中，作爲加工手段的複數 種類的工具30，是被裝設在無圖示的刀具台。從工件200 的主軸10突出的部分，是藉由與工具30接觸來進行切削、 旋削、穿孔等的加工。 工具3 0，是在側面視，對於鉛直方向傾斜地被配置（ 第1圖（c )參照）。 在與主軸10的前端側相面對的位置中，具備第2主軸 20 · 主軸10、第2主軸20及工具30，是被具備開閉窗51的 蓋5 0所覆蓋。被此蓋50所覆蓋的內部，是構成加工部40。 此加工部4〇，是設在基部也就是自動車床100的床台 60上。床台60的內部，是成爲供收容電氣設備裝置等用的 收容部70。此收容部70，是如第1圖（b) 、 （c)所示在 背面側設有開口的門6 1、62、63。 這些門61、62、63，是位於背面側，且當收容部70內 的電氣設備裝置的維修等的作業時可被打開。由此，成爲 -10- 201206591 在自動車床1 00的背面側空間進行維修檢點。 在成爲加工部40的背面側的蓋50的背面側（第1圖（a )的前視圖的深度方向的背側）的領域且在收容部70的1 方，形成有空間45。在此空間45中設有給材部80，其可收 容應藉由被配置於此自動車床1〇〇側方的其他的自動車床 被加工的工件200A，並且將被收容的工件200A供給至被 配置於側方的其他的自動車床。在此，工件200A，是長條 的棒材。且，該工件200A是在與主軸10平行地延伸的狀態 (並設於主軸1 〇的狀態）被收容於給材部80。 空間45，是沿著工具30的傾斜並朝向下方擴大的方式 形成，可以確保比較大的給材部8 0的設置空間。 此給材部8 0，是與一般的給材裝置同樣的構成，詳細 的話例如日本特開平5-42 445號公報的第1圖所示，具備： 材料棚，是收容多數的工件200A ;及供給機構，是將被收 容於此材料棚的多數的工·件2 00A之中的1個，朝向鄰接配 置於自動車床100右側方的其他的自動車床的主軸送出。 給材部80，是將工件200A橫跨兩主軸10、20的背面側 地並設在兩主軸10、20。且，此給材部80，是朝向與對於 自動車床100本身的主軸10被供給的工件200的供給方向相 反的方向，送出其他的自動車床用的工件2 00 A。 由此，其他的自動車床用的工件200A，是不會比床台 60及蓋50極端突出地被收容，與不具備給材部8〇的自動車 床相比’本實施例的自動車床100的橫寬度的增加被抑制 -11 - 201206591 特別是，本實施例的自動車床100中，其他的自動車 床用的工件200A的長度，適用一般爲了將2個主軸10、20 相面對配置所需要的接近工作機械的寬度方向的尺寸（大 致2〜2.5m前後）。由此，可以由與床台60及蓋50的寬度 尺寸大致等同的寬度收容工件200 A。 且，如第2圖所示，說明將本發明的工作機械的2台的 自動車床101、102鄰接於彼此側方配置的情況。此情況， 使一方的自動車床101的主軸1〇及另一方的自動車床102的 給材部80a相面對的方式，將自動車床101、102對稱地設 置。由此，一方的自動車床1 〇 1的給材部8 0，是將被收容 的工件200A，與主軸10平行地，沿著另一方的自動車床 102的主軸l〇a供給。因此，不需要在各自動車床101、102 另外設置給材裝置。 因此，藉由在兩自動車床1 0 1、1 0 2之間另外設置的給 材裝置，不會塞住各自動車床1 〇 1、1 02的維修時時被利用 的作業領域（例如朝背面側打開的門6 1、62、63、6 1 a、 6 2 a、6 3 a的開閉所需要的領域也就是背面側空間）、和加 工時的作業空間（正面側空間），就可容易地進行各自動 車床1 0 1、1 〇 2的巡回監視和收容部7 0、7 〇 a的維修。 且，將2個自動車床1 0 1、1 02配置於彼此的側方的狀 態（第2圖參照）中的橫方向的佔有空間，不會超過將大 致2個自動車床1〇1、1〇2的橫寬度合算的長度的空間。因 此，與如習知’爲了確保維修用的空間等而在2個自動車 床之間，將另外2個給材裝置背向貼合（背面彼此相對面 -12- 201206591 的狀態）配置的2個工作機械組是佔有的橫方向的空間（ 第5圖參照）相比，可以更減小橫方向的佔有空間。 如此，依據本實施例的自動車床1 〇 1、1 02 ,即使在將 2個集合並配置於彼此的側方的對稱狀態下，也不會使維 修性下降，可以減小橫方向的佔有空間。 又，本實施例的自動車床1 〇 〇，是如第3圖所示，將第 2主軸2 0，設在大致沿著工具3 0的傾斜的方式被傾斜配置 的軌道21上，將第2主軸20藉由第2主軸用馬達22 (第2主 軸移動手段）沿著軌道2 1移動，將被把持在第2主軸20的 工件200藉由第2工具群31加工的方式構成也可以。 如此在將加工部4 0傾斜地配置於床台6 0上的傾斜構成 的自動車床1 〇〇中，在收容部70及軌道2 1的延長線之間， 原本存在死空間。 在此，可以將此死空間作爲前述的空間45設置給材部 8〇，對於未設有此給材部80的習知的工作機械，可以不會 極端增大其深度方向尺寸及高度方向尺寸地配設給材部80 〇 又，工件200、200A，除了如前述實施例的長條的棒 材（桿材）以外，作爲在預先成形成預定的形狀的素形材 等，供給至其他的自動車床等的工作機械的方式構成也可 以。 【圖式簡單說明】 [第1圖]顯示作爲本發明的工作機械的自動車床的圖， -13- 201206591 (a)是顯示前視圖，（b)是顯示平面圖，（c)是顯示 左側視圖，（d )是顯示右側視圖。 [第2圖]顯示將作爲本發明的工作機械的自動車床呈橫 方向2個並列配置的狀態的圖，（a )是顯示前視圖，（b )是顯示平面圖，（c )是顯示左側視圖，（d )是顯示右 側視圖。 [第3圖]顯示將第2主軸沿著軌道朝背面側斜上方可移 動的變形例的自動車床的圖，（a)是顯示前視圖，（b) 是顯示平面圖，（c )是顯示左側視圖，（d )是顯示右側 視圖。 [第4圖]顯示將習知的工作機械配置2個的情況時，將 —方的工作機械及另一方的工作機械用給材裝置配置成背 向貼合的狀態的平面圖。 [第5圖]顯示將習知的工作機械配置2個的情況時’將 一方的工作機械用給材裝置及另一方的工作機械用給材裝 置配置成背向貼合的狀態的平面圖。 【主要元件符號說明】 1 0 :主軸 1 0a :主軸 20 :第2主軸 21 :軌道 22:第2主軸用馬達 30 :工具 -14- 201206591 3 1 :第2工具群 4 0 :加工部 45 :空間 50 :蓋 5 1 :開閉窗 6 0 :床台 61，62，63，61a，62a，63a·· f1^ 7 〇 :收容部 7〇a :收容部 8 〇 :給材部 8 0 a :給材部 1 00 :自動車床 1 01 :自動車床 102 :自動車床 2 0 0 :工件 2 0 0 A :工件 -15-201206591 VI. EMBODIMENT OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION The present invention relates to a work machine, and more particularly to a work machine including a feed portion for supplying an object to be processed. [Prior Art] A working machine such as a lathe is used to hold a workpiece (workpiece) such as a long round bar on a spindle, and to cut it in a machining field in which a tool such as a turning tool, a drill, or a reamer is provided. Processing. The workpiece to be processed is supplied from a feeder device different from the body of the machine tool. In this material feeding device, a large number of workpieces are housed inside, and these accommodated workpieces are automatically supplied to the spindle of the machine tool in sequence. Here, the working machine has a certain lateral width (length in the left-right direction as seen from the front) in order to process the above-mentioned workpiece. In addition, the material feeding device is also required to be long in the right and left directions in order to accommodate long workpieces. Further, the material feeding device is used in the side of the main body of the working machine because it is necessary to supply the workpiece along the main shaft of the working machine (for example, see Patent Document 1). [PRIOR ART DOCUMENT] [Patent Document] Patent Document 1: Japanese Laid-Open Patent Publication No. Hei No. Hei 5 No. Hei. No. Hei. No. Hei. No. 5-201206591 (Problems to be Solved by the Invention) In this case, when one machine is installed, it is required. An installation space having a lateral width of a length that balances the lateral width of the working machine itself and the lateral width of the material feeding device. However, in the case where the front side of the working machine and the feeding device requires the space that the operator enters (front side space), especially in the case of an automatic working machine such as NC (digital control), it is necessary to set an operator for one person. The patrol monitors the space of the working machine path of the plurality of stations. Further, in the lower portion of the processing field of the machine tool, mechanical oil required for processing is stored, and a housing portion for accommodating various mechanical and electrical equipment and the like is disposed. Therefore, in this accommodating portion, a door or a lid that can be opened or closed or detachable is provided on the back side of the working machine (the back side of the front side). Further, when the electric equipment or the like inside the accommodating portion is repaired, the door or the cover is opened or removed, and then the inside of the accommodating portion is carried out. Therefore, in consideration of the above-described maintenance work, there is a need to secure a certain amount of space (back side space) on the back side of the machine tool. On the other hand, such work machines are used in workshops, and very few of them are used alone. Generally, a plurality of units are set and operated at the same time. Here, in the case of one of the above-described working machines, a single feeding device is arranged in parallel with the working machine. However, when a large number of working machines are installed, it is required to effectively use the installation space. Here, from the viewpoint of effective use of the installation space, as shown in the plan view of Fig. 4, it is considered that the two groups of workers -6 - 201206591 composed of the machine tool and the material feeding device are arranged in a back-to-back manner. In this case, the back side of the working device of the other working machine group is positioned on the back side of the working machine of one of the working machine groups, and the back side of the working machine of the other working machine group is placed at one of the working machines. The back side of the set of feedstock devices. Thereby, the two sets of working machine groups are arranged in point symmetry with each other. However, this arrangement is effective when the point of the occupied space (horizontal width) in the lateral direction is reduced, but the space on the back side of each working machine of the two working machine groups is fed by the feeding device of the other working machine group of each other. Plugged, and the maintainability is degraded. Here, as shown in the plan view of Fig. 5, the feeding devices of the two sets of working machine groups are arranged to be facing each other. In this case, the back side of the feeding device of the other working machine group is located on the back side of the feeding device of one of the working machine groups. Thereby, the maintenance of the space on the back side of each machine tool is prevented from being lowered. However, when the two sets of working machine groups generated by this arrangement are seen from the front, the front side of one of the working machines, the two sets of feeding devices located at the front and the rear, and the back of the other working machine are arranged side by side in the horizontal direction. The state of 'there is a problem that the occupied space in the horizontal direction becomes large. In addition, when the space in the horizontal direction is increased, when the working machine group is placed in a space defined in advance such as a landform such as a factory, the arrangement direction and the like are limited, and there is a problem that the space cannot be effectively utilized. The present invention has been made in view of the above circumstances, and it is an object of the invention to provide a working machine which can reduce the maintainability in a state in which a plurality of sets of two or more are arranged, and can reduce the occupied space in the lateral direction. 201206591 (Means for Solving the Problem) In order to achieve the above object, the machine tool of the present invention includes a spindle that holds the object to be processed, and processes the object to be processed in a processing portion that is equipped with the spindle. The object to be processed which is processed by another work machine on the side of the work machine is placed in the main shaft, and the object to be processed is supplied to the feed portion of the other work machine. Processing the area on the back side. [Effects of the Invention] According to the working machine of the present invention, the working portion of the field on the back side of the processed portion of the working machine is integrated, and the other working machine on the side of the working machine to which the present invention is placed is The additive is supplied (hereinafter referred to as a workpiece). Therefore, it is not necessary to separately provide the material feeding device in the other machine, and the dimensionality of the working machine of the present invention is not lowered. Further, by using the other working machine as the machine of the invention, the occupied space in the lateral direction can be made smaller than ever. In other words, in the machine tool of the present invention, the workpiece to be processed by another work is accommodated, and the workpiece is supplied to the other work machine, and is provided in the field of the back side of the processed portion in which the spindle is disposed. It is possible to supply the material contained in the material portion from the field on the back side of the processing portion to another machine tool. That is, in the machine tool of the present invention, only the other machine tools are placed on the side of the machine tool of the present invention, and the work bar of the present invention is placed there, and the object supply portion is placed here. The workpiece of the machine tool 8 - 201206591 can be supplied to the spindle of the other machine tool. Therefore, in the working machine of the present invention, it is not necessary to additionally provide a feeding device in the other working machine. Here, the other working machine can be applied to the working machine of the present invention. In this case, the two working machines of the present invention are arranged side by side on the other side. Therefore, in each of the working machines of the present invention, the workpieces that are accommodated in the feed portion of the other working machine are supplied by the material portion. Therefore, in each working machine, it is not necessary to separately provide a feeding device corresponding thereto. Therefore, as is customary, the feeding device provided in each working machine does not block the working area (for example, the back side space) used for the maintenance of the other working machine and the working space during processing (front side space) ). Further, the space occupied by the two working machines of the present invention in the lateral direction of each other does not exceed the space in which the lateral widths of the two working machines are combined. Therefore, in the machine tool of the present invention, for example, it is possible to reduce the occupation of the two working machine groups in which the two feeding devices are attached to each other (the state in which the back faces face each other). The space of the direction. When the work machine according to the present invention is disposed in a state in which a plurality of sets of two or more are disposed, the maintainability is not lowered, and the space occupied in the lateral direction can be reduced. [Embodiment] Fig. 1 is an automatic -9 - 201206591 lathe 100 showing an embodiment of the working machine of the present invention. The automatic lathe 100 is a working machine for cutting, turning, and piercing a long rod bar that is held by the spindle 10, that is, a workpiece 2000 (object to be processed). The workpiece 200 is supplied from the side of the rear end side of the main shaft 1 即, that is, the right side of the drawing, and is held by the main shaft 1 as shown in the front view of Fig. 1(a) and the plan view of Fig. 1(b). Then, by the rotation of the main shaft 10 about the axis, it is sent out along the axis in the left direction of the figure. In the front end (front end) side of the main shaft 1 ,, a plurality of types of tools 30 as processing means are mounted on a tool holder (not shown). The portion protruding from the main shaft 10 of the workpiece 200 is processed by cutting, turning, perforating, or the like by contacting the tool 30. The tool 30 is arranged sideways and is disposed obliquely to the vertical direction (refer to Fig. 1(c)). The second main shaft 20, the main shaft 10, the second main shaft 20, and the tool 30 are provided at a position facing the front end side of the main shaft 10, and are covered by a cover 50 having an opening and closing window 51. The inside covered by the cover 50 constitutes the processed portion 40. The processing portion 4 is provided on the bed 60 of the base, that is, the automatic lathe 100. The inside of the bed 60 is a housing portion 70 for housing an electric equipment or the like. The accommodating portion 70 is a door 6 1 , 62 , 63 having an opening on the back side as shown in Figs. 1 (b) and (c). These doors 61, 62, and 63 are located on the back side and can be opened when the electric equipment of the accommodating portion 70 is repaired or the like. As a result, -10- 201206591 performs a maintenance checkpoint on the back side space of the automatic lathe 100. A space 45 is formed on one side of the accommodating portion 70 in the field of the back side of the cover 50 on the back side of the processed portion 40 (the back side in the depth direction of the front view of FIG. 1( a )). In the space 45, a material portion 80 is provided which can accommodate the workpiece 200A to be processed by another automatic lathe disposed on the side of the automatic lathe 1b, and supplies the accommodated workpiece 200A to the configured Other automatic lathes on the side. Here, the workpiece 200A is a long bar. Further, the workpiece 200A is housed in the material portion 80 in a state in which it extends in parallel with the main shaft 10 (and is provided in the state of the main shaft 1 〇). The space 45 is formed along the inclination of the tool 30 and enlarged downward, and the installation space of the relatively large material portion 80 can be secured. The material portion 80 is the same as the general material feeding device. In the first embodiment of the Japanese Patent Publication No. 5-42445, the material shed is provided with a plurality of workpieces 200A; The supply mechanism is one of the plurality of workpieces 20 00A that are housed in the material shed, and is sent toward the main shaft of another automatic lathe that is disposed adjacent to the right side of the automatic lathe 100. In the material feeding portion 80, the workpiece 200A is placed on the back sides of the two main shafts 10, 20 and provided on the two main shafts 10, 20. Further, the material portion 80 sends a workpiece 200 00 A for another automatic lathe in a direction opposite to the supply direction of the workpiece 200 supplied to the main shaft 10 of the automatic lathe 100 itself. Therefore, the workpiece 200A for another automatic lathe is not protruded more prominently than the bed 60 and the cover 50, and the automatic lathe 100 of the present embodiment is compared with the automatic lathe that does not have the material portion 8〇. The increase in the lateral width is suppressed -11 - 201206591 In particular, in the automatic lathe 100 of the present embodiment, the length of the workpiece 200A for other automatic lathes is generally required to face the two main shafts 10 and 20 facing each other. It is close to the dimension of the working machine in the width direction (approximately 2 to 2.5 m front and rear). Thereby, the workpiece 200A can be housed in a width substantially equal to the width dimension of the bed 60 and the cover 50. Further, as shown in Fig. 2, the case where the two automatic lathes 101 and 102 of the machine tool according to the present invention are arranged adjacent to each other will be described. In this case, the automatic lathes 101 and 102 are symmetrically disposed such that the main shaft 1〇 of one of the automatic lathes 101 and the feeding portion 80a of the other automatic lathe 102 face each other. Thereby, the material portion 80 of one automatic lathe 1 〇 1 is supplied to the workpiece 200A to be accommodated, parallel to the main shaft 10, along the main axis l〇a of the other automatic lathe 102. Therefore, it is not necessary to separately provide a feeding device for each of the automatic lathes 101, 102. Therefore, by the feeding device separately provided between the two automatic lathes 10 1 and 1 0 2, the working areas to be utilized for the maintenance of the automatic lathes 1 〇 1, 102 are not blocked (for example, toward the back side). The area required for opening and closing of the side-opening doors 6 1 , 62 , 63 , 6 1 a, 6 2 a, and 6 3 a is the back side space, and the working space (front side space) during processing can be easily The patrol monitoring of each automatic lathe 10 1 , 1 〇 2 and the maintenance of the accommodating parts 70, 7 〇a are performed. In addition, the space occupied by the horizontal direction in the state in which the two automatic lathes 10 1 and 102 are disposed on the side of each other (see FIG. 2) does not exceed approximately 2 automatic lathes 1〇1, 1〇. The space of the length of the horizontal width of 2 is sufficient. Therefore, two of the two feeding devices are placed back to each other (the state in which the back faces are facing each other -12-201206591) between the two automatic lathes in order to secure the space for maintenance and the like. The working machine group can reduce the occupied space in the lateral direction as compared with the space in the horizontal direction (refer to FIG. 5). As described above, according to the automatic lathes 1 and 1, 02 of the present embodiment, even in the symmetrical state in which the two sets are arranged sideways, the maintainability is not lowered, and the occupied space in the lateral direction can be reduced. . Further, in the automatic lathe 1 of the present embodiment, as shown in Fig. 3, the second main shaft 20 is provided on the rail 21 which is inclined so as to be inclined substantially along the inclination of the tool 30, and the second The spindle 20 is moved along the rail 2 1 by the second spindle motor 22 (second spindle moving means), and the workpiece 200 held by the second spindle 20 may be processed by the second tool group 31. In the automatic lathe 1 构成 which is formed by tilting the processing unit 40 obliquely on the bed 60, there is originally a dead space between the extension of the accommodating portion 70 and the rail 2 1 . Here, the dead space can be provided as the aforementioned space 45 to the material portion 8A. For the conventional working machine not provided with the material portion 80, the depth direction dimension and the height direction dimension can be not extremely increased. In addition to the long bar (rod) of the above-described embodiment, the workpieces 200 and 200A are supplied to other materials as a plain material or the like which is formed into a predetermined shape in advance. It is also possible to configure the working machine such as an automatic lathe.
