Description of the invention (5) ○ Below, by inserting the frame mounting pin 7 of the frame 3 into the hole 2 8a of the fixture 2 8 of the inner box 4, the frame 3 is mounted on one side of the inner box 4 and the inner box The opening of 4 becomes the free state of the switch. The cut-out portion 25 of the control board 23 is placed on the mounting piece 2 2 of the inner box 4 * The control board 2 can be pressed by inserting the pin 26 into the hole 2 4 and pressing into the hole 1 9 of the inner box 4 3 Installed on the back of the inner box 4. After assembling in this way, the coin processing unit 35 is mounted on the inner box 40, that is, the coin processing unit 35 is mounted on the flat plate-shaped rotating plate 36 through a bracket (not shown). At one end of the rotating plate 36, a pair of arms 37, 37 facing the upper and lower parts and a lower arm 38 are formed by bending, and the rotating plate 36 is supported between the arms 37, 37 via The shaft 39 is framed at one end of the first link member 40 having a c-shaped cross section, and the arm portion 38 is framed at one end of the second link member 42 via the shaft 41 frame. Then, the other end of the first link member 40 is mounted on one side of the inner box 4 by a shaft 43 supported by a pair of support blocks 32, 32 of the inner box 4. Also, the other end of the second link member 4 2 is attached to one side of the inner box 4 via a shaft 4 4 frame supported by the support block 3 3 of the inner box 4. As shown in Figure 4, the shaft 4 3 and the shaft 4 4 are fixed to the inner box 4 at a deviated position in plan view, the rotating plate 36 and the first and second link members 4 0 ′ 4 2 constitute 4 sections Rotating mechanism, coin handling unit 3 5 series is applicable to the Chinese stock house standard (CNS) Λ4 present format (2 | 〇κ 297 male yak) at this paper scale (please read the precautions on the back before filling this page) Order ~ 8- A7 _B7_ printed by the Employee Consumer Cooperative of the Central Sample Falcon Bureau of the Ministry of Economic Affairs 5. Description of the invention (6) The state of turning freely in the direction of BB in the figure 4 becomes a state of easy insertion and removal from the opening of the inner box 4. After that, the coin processing unit 35 is rotated in the direction of arrow B in the > figure as shown in the fourth figure, and is accommodated in the inner box 4 from the opening of the inner box 4 and fixed in the inner box by fixing means not shown Box 4. Then, after rotating the frame 3 with the frame mounting pin 7 as the center of rotation to close the front opening of the inner box 4, the operation lock 9 is rotated by the gun key and the locking lever 8 is rotated to engage the locking block 31 to perform the process 3 Locked. The public telephone set 1 assembled in this way is exposed to the front end of the screw 2 0 only on the back side of the frame body 2 which is irrelevant to the wall and is not related to the t-view. Exterior. In addition, since the control board 23 and the coin processing unit 35 are configured to be mounted on the frame body 2 via the inner box 4, there is no need to install the control board 23 and the coin processing unit 35 separately in the frame as in the past. The bracket of the body body 2 is fixed to the frame body 2 by welding, so the assembly operation can be simplified, and the hinge of the frame mounting frame 3 is not needed, and the locking block 3 1 is formed by the locking block that locks the locking lever 8 Since the inner box 4 is made of synthetic resin, the number of parts can be reduced. In addition, by installing these 3, the control board 23, and the coin processing unit 35 to the inner box 4, the inner box 4 is used to position these three members, so that it is not necessary to perform each adjustment as in the past, and the adjustment time can be shortened. Also, since the coin processing unit 35 is framed on the other side opposite to one side of the inner box 4 in which the frame 3 is framed, the first link member 40, 4 is formed via the rotating plate 36, The 4 sections of the rotating mechanism and the paper inserted by 2 apply the Zhongguanjia standard (CNS) Λ4 specification (210X297 official celebration) ~-9 — (please read the precautions on the back before filling this page)

Therefore, the coin handling unit 3 5 or the control board 23 Inspection work becomes easy. In addition, in this embodiment, an example of a coin-type public telephone set is exemplified, but it is not limited to this, and a card-type public telephone set may also be used instead of a coin processing unit at this time to determine whether a card is good or bad. And the card processing unit that rewrites the data with the number of calls on the good card can be used. It can also be used in combination with coins and cards. At this time, the coin processing device and the card processing device become Unit I is enough. In addition, the frame 3 is attached to one side of the inner box 4 by a frame mounting pin 7, but it may be detachably attached to the inner box 4. [Effects of the Invention] As described above, according to the structure of the public telephone of the present invention, a frame body having a front opening and formed in a box shape, and an opening and closing opening of the frame body can be opened and closed in the frame body A public telephone in which a processing unit for processing coins and the like and a control board of a control device body is contained in the body, is characterized by comprising the above-mentioned stern, a processing unit and a control board, and a detachable synthetic resin place is formed inside the frame body The inner box. There is no need to fix the bracket and the like used for mounting the control board and the coin processing unit to the frame body separately by welding to the frame body as in the past, so the assembly work becomes easy. In addition, by installing these control boards and coin processing units in the inner box, the paper size is applicable to the Chinese National Standard (CNS) Λ4 present grid (210X 297gf) (please read the precautions on the back before filling this page Order-10-308678 A7 B7 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V.
