A small hole is punched in the magnetic card by the punch mechanism, and a guideline for the remaining balance is displayed. As such a punch mechanism, a punch mechanism composed of a punch pin, a punch base, an electromagnetic solenoid and the like is most common (eg, JP-A-56-487).
No. 8). If the punch residue produced by the small holes is accumulated inside the device, it may interfere with the smooth transportation of the card or cause a failure, so it must be discharged to the outside.
Therefore, for example, in the punch dust processing apparatus disclosed in Japanese Patent Laid-Open No. 58-208873, the punch dust is guided to the box by a pipe.

[Problems to be Solved by the Invention] In the above-described conventional punch residue discharging device, since the pipe is fixed to the frame by a plurality of brackets, the pipe mounting work is troublesome and the number of parts is increased. There was a flaw. In addition, when the card reader is attached to both sides of the attachment wall, the left and right card readers are upside down, so the pipes must be attached in opposite directions, but it is necessary to provide screw holes or the like for that in advance. is there.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to reduce the number of assembling steps and the number of parts, and to easily install a pipe even when it is turned upside down. Another object of the present invention is to provide a punch residue discharge structure of a punch mechanism that can reliably guide the residue into the punch residue storage case.

[Means for Solving the Problems] The present invention has been made in order to achieve the above object, and the first invention thereof is that a pair of frames facing each other in parallel and forming a card transport path are made of synthetic resin. Molded and attached to one frame a punch mechanism consisting of an electromagnetic solenoid and a punch base that face each other across the card transport path,
The other frame is provided with a through hole for discharging punch residue corresponding to the punch hole of the punch table, and a holding member for holding a punch residue discharging member on both side walls of the other frame corresponding to the through hole. Each groove is formed.

In a second invention, a punch residue discharging member is attached between the through hole and the holding groove, and the punch residue discharging member is T
It is formed in a V shape and can be discharged in any of the vertical and horizontal directions of the frame.

[Operation] In the present invention, the holding grooves provided on both side walls of the other frame hold the punch residue discharging member. When the card reader is turned upside down, the T-shaped punch residue discharge member forms the discharge port by opening the opening that has been lower so far up and the opening that has been lower upside down.

[Embodiment] Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

In these figures, 1 is a mounting wall, 2 is a card reader, and this card reader 2 is a fixed frame 3 mounted on the mounting wall 1 by a bracket or the like (not shown),
The movable frame 4 is provided in parallel with the fixed frame 3 at a predetermined interval. The fixed frame 3 and the movable frame 4 are each formed of a synthetic resin having excellent wear resistance, and a gap between the two frames forms a card transport path 6 for the magnetic card 5. The fixed frame 3 is formed in an I-shaped cross section, and is composed of a vertical substrate 3A that guides one surface of the magnetic card 5 and a pair of side wall plates 3B and 3C that face each other in parallel in the vertical direction. . On the other hand, the movable frame 4 is arranged so as to be openable and closable with respect to the fixed frame 3 for the purpose of preventing card jams and the like.

A concave portion 7 is formed on an inner surface of a part of the vertical substrate 3A of the fixed frame 3 on the lower end side, and the movable frame 4 is correspondingly formed.
A punch mounting portion 8 is recessed on the inner surface of the. Also,
A through hole 11 is formed in the center of the punch mounting portion 8 and through which an electromagnetic solenoid 10 that constitutes the punch mechanism 9 penetrates. A flange portion 12 is integrally provided on the peripheral portion of the electromagnetic solenoid 10 on the fixed frame 3 side.
Is fixed to the punch mounting portion 8 by a set screw 13. Further, the electromagnetic solenoid 10 has a card carrying path 6
The punch bases 15 opposed to each other with the punches sandwiched therebetween are fixed by set screws 16. The punch bases 15 are positioned in the recesses 7 of the fixed frame 3 when the movable frame 4 is closed.

Plunger (movable iron core) 17 of the electromagnetic solenoid 10
A punch pin 18 is formed at the end of the punch table 15 side, and a punch hole 19 is formed in the center of the punch table 15 correspondingly. Further, a through hole 21 is formed in the center of the recess 7 so as to correspond to the punch hole 19.

Holding grooves 23 and 24 for holding the punch residue discharging member 22 are formed in the end faces of the pair of upper and lower side wall plates 3B and 3C of the fixed frame 3 on the side of the mounting wall 1 respectively corresponding to the through holes 21. . These holding grooves 23 and 24 are formed in a semicircular shape with a hole diameter substantially the same as the outer diameter of the punch residue discharging member 22, and the upper and lower ends of the punch residue discharging member 22 utilize the elastic deformation of the material. It is configured to be press-fitted. The punch residue discharge member 22 is a T-shaped pipe made of synthetic resin, and the tip end of the branch pipe 22A is fitted in the through hole 21. A punch dust storage case 25 is installed below the punch dust discharge member 22.

In such a configuration, when the magnetic card 5 is inserted between the fixed frame 3 and the punch base 15 and stopped after the end of the call, the electromagnetic solenoid 10 is excited by the punching signal.
Then, since the movable iron core 17 is attracted, the punch pin 18 moves leftward integrally with the movable iron core 17 to form a small hole in the side edge portion of the magnetic card 5. The punch residue generated by the formation of the small holes passes through the through hole 21 and passes through the punch residue discharging member 22 to be dropped and stored in the punch residue storage case 25.
