Description: The invention relates to an installing structure for a dealing board as indicated in the precharacterizing part of claim 1. A prior art (JP-A-60084623) dealing board or keyboard is provided at a computer operation desk in which a board for a display is fixed to its top end to mount and support the display thereupon. One side part of the keyboard is sandwiched between top parts of leg members of the operation desk, whereas the other end part of the keyboard is supported rotatably around a fixed knob as a fulcrum. For adjusting the tilt angle of the keyboard an operator loosens the fixed knob to adjust the keyboard to a desired angle and clamps it fixably after this adjustment. A similar device is disclosed in DE-A-37 36 891 in which a display apparatus can be adjusted to vary its tilting angle with respect to an operation desk or keyboard. The surface area between the front edge of the operation desk and the display apparatus is always independent from the location and/or the tilting angle of the display apparatus. It is the object of the invention to provide an installing structure for a dealing board which improves the workability in assembly the dealing board within an operation desk. This object is solved by the features as claimed in claim 1. As the case of the dealing board is of a box type, it is possible to improve the workability to assemble the dealing board. As the box-like case of the dealing board is slanted rearwardly to the top plate of the desk, the user of the dealing board can prevent its knee from hitting the dealing board. As the length of the front fixture, the angle in which the front fixture is secured to the top plate, and the length of the rear fixture, the angle in which the L-shape portion is bent into L-shape, are adjustable before inserting of the dealing board through the open portion, it is possible to adjust the angle of the control panel. According to a further development of the invention, by screwing a screw through the screw hole of the engagement portion to the rear fixture so as to control the slant angle of the control panel, it is possible to set the angle of the panel according to the desire of the customer without a manufacture of the dealing board according to the particular desire of the customer. It is easy to standardize the angle of the panel, and it is not necessary to previously prepare or stock many dealing boards of plural kinds making management of the case of the dealing board easy. According to a still further development of the invention the print substrate and the control panel are disposed in parallel with the bottom face of the case and the case is installed slantly. Due to this the print substrate is slanted so that heat stream generated from the various electronic parts flows along the print substrate so as to radiate effectively the heat. An embodiment of the invention is explained in detail in connection with the drawings in which Figure 1 is a perspective view showing the whole structure of the dealing board; Figure 2 is a section showing the dealing board main body; Figure 3 is a section showing a usage condition of the dealing body; Figure 4 is an enlarged view of the portion shown by IV; and Figure 5 is also an enlarged view of the portion of V. As clearly depicted in Figure 1, the dealing board consists of a main body 20, a desk 21, a display 22 displaying economy information, a hand-set 23, and a microphone 24. The dealing board main body 20 has a box-like case 25, as shown in Fig 2, and the case 25 has a control panel 25a fixed to the topface of the case. A bottom face 25h of the case 25 is in parallel with the control panel 25a and the front face 25f and the rear face 25g of the case 25 is at a right angle to the control panel 25a. Assembling process of the control panel 25a to the case 25 will be described. It is apparent from Fig 4 that, at the rear portion of the control panel, there are an engagement piece 25c to be engaged from below with the edge portion 25b of the opening formed in the case 25, and a fixing piece 25d of substantially a L-shape as shown in Fig 5 so as to attach to the front portion of the control panel. The engagement piece 25c is engaged with the edge portion 25b of the opening as shown in Fig 4 and the fixing piece 25d is secured to a stable piece 25e protruding downward from the edge portion 25b by means of a screw 26 as shown in Fig 5, thereby the control panel 25e is secured to the case 25. On the other hand, two layers of the upper and the lower print substrates 27 and 28 are placed under the control panel 25a (Fig 2). The upper print substrate 27 has a function button 29 exposed from the control panel 25a, as well as a spacer 30 is placed between respective print substrates 27 and 28. These print substrates 27 and 28 are fixed on the rear face of the control panel 25a so as to be in parallel to each other. A pair of connectors 31a and 31b joins electrically the upper print substrate 27 to the lower one 28. The function button 29 installed on the upper print substrate 27 has a conductive contact rubber 29a (see Fig 4) at its lower end. Pushing down the function button 29 makes the conductive contact rubber 29a contact the contact 27a formed on the print substrate 27 so as to carry out ON-OFF operation of the circuit. In addition, other print substrates 33, 34, and 44 are securely installed in the bottom space of the case 25. The lower print substrate 44 is installed in the bottom space so as to be in parallel with the bottom face 25h of the case 25 through a set of spacers 35. While, the upper print substrate 34 is placed above the lower print substrate 44 in parallel with the print substrate 44 through a set of other spaces 36. The other upper or top print substrate 33 is connected to the upper print substrate 34 securely by connectors 45a and 45b. Both the print substrates 33 and 44 are electrically connected to each other by a system of the connector 33a, a signal cable 38a, and the other connector 34a. Respective print substrates 33 and 28, which is secured to the side of the control panel 25a, are electrically connected by means of a system of connectors 28a and 33b, and a signal cable 37, as well as the bottom print substrate 44 and a main body of a telephone exchanger (not shown) are connected by a signal cable 38b. While, the top plate 21a of the desk 21 on which the dealing board main body 20 is mounted has an open portion 21b open a little larger than the area of the dealing board main body 20. On the lower face of the open portion 21b, fixtures 40 and 41 are secured. The fixture 40 installed at the front side of the open portion 21b is longer than that at the rear side of the open portion 21b. Both upper end portions of the fixtures 40 and 41 are secured to the lower face of the top plate 21a by small screws 42. The lower portion of the front fixture 40 is rearward slanted and has a lowest L-shape end portion or engagement portion 40a. While, the other rear fixture 41 has a main portion extending in a right angle to the top plate 21a and a top end portion extending from the main portion at a right angle and being secured to a bottom face of the top plate 21 by a small screw 42 as described above. In addition the fixture 41 has a bottom or lowest engagement portion 41a extending slantly and downward and an angle adjusting screw 43 is inserted from the below through the lowest engagement portion 41a. The bottom face 25h of the case 25 of the dealing board main body 20 inserted from above through the open portion 21b of the desk 21 is supported from the bottom by a front end of the angle adjusting screw 43 and the engagement portion 40a of the fixture 40 so as to slant to the front the control panel 25a relative to the upper face of the top plate 21a of the desk 21. By adjusting the angles of the fixtures 40 and 41 and the angle adjusting screw 43 before inserting of the dealing board main body 20 through the open portion 21b, it is possible to adjust at will the angle of the control panel 25a of the dealing board main body 20 according to the particular demand of the customers. According to the embodiment above, the fixing angle of the front fixture 40 is set so as to make the slanting angle  of the control panel 25a about 20° degree. As a result, presupposing that the length of the top plate of the desk 21 is about 350 mm, the length L 2 of legs of the user is about 500 mm, the working space L 3 is about 450 mm, and the length L 4 of the dealing board main body 20 is about 200 mm as shown in Fig 3, a slanting distance L 1 of the bottom face of the dealing board main body 20 becomes about 68 mm. The distance is sufficient to general users, so that even the length L of the top plate is made short, the knee B of the user A hardly hit the main body 20 resulting in a small size of the desk 21. Because the print substrates 33, 34, and 44 are fixed in the bottom space of the main body 20 in parallel with the top face of the control panel and the case 25 is installed slantly, these print substrates 33, 34, and 44 are slanted, so that heat stream 48 shown by an arrow in Fig 2 flows along these print substrates 33, 34, and 34 effectively radiating heat generated from the various electronic parts mounted thereon. According to the embodiment above, the engagement piece 25c and the fixing piece 25d are secured to the control panel 25a through for example a welding method, however they may be formed by a molding process of resin. In the latter case, the control panel 25a, the case 25, and the fixing piece 25e at the case side may be molded. Furthermore, the front and the rear walls 25f and 25g of the case 25 are formed so as to be at a right angle to the plane of the control panel 25a, however it is not necessary to form these walls and right and left walls (not shown) of the case 25 at a right angle to the control panel 25a on condition that at least the bottom face 25h is in parallel to the control panel 25a. These walls may be arranged in a shape of diamond seeing from right or left side of the case 25.
