[Problems to be solved by the device]

 However, in the above-mentioned conventional configuration, the columnar member for preventing dust from entering the magnetic card traveling path and the means for obtaining the information recording clock signal are separately provided, so that the number of parts is large and the mechanism is complicated. Had a problem. The present invention solves the above conventional problems, and an object of the present invention is to provide a magnetic card reader / writer having a small number of components and a simplified mechanism.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a cylindrical member that rotates in response to the movement of a magnetic card in the magnetic card running path near the magnetic card insertion slot to prevent dust from entering the magnetic card running path. A signal having the same density as the magnetic recording density to be recorded by the magnetic head is recorded on the outer surface of the cylindrical member to prevent intrusion, and a signal detection means is provided so that the detected signal is used for information recording of the magnetic head. It is a clock signal.

[0005]

[Action]

 Therefore, with the above configuration, the columnar portion for preventing dust from entering the magnetic card running path and the rotating member for obtaining the information recording clock signal are shared, so that the number of parts can be reduced and the mechanism can be simplified.

【Example】

 FIG. 1 is a perspective view of a magnetic card reader / writer according to an embodiment of the present invention, FIG. 2 shows a state before a magnetic card according to an embodiment of the present invention is inserted, and FIG. It shows the configuration of the state. 1 to 3, 1 is a card running path, 2 is a magnetic card, 3 is a cylindrical member, 4 is a magnetic head, 5 is a magnetic body, 6 is a magnetic head, 7 is a magnetic stripe, 8 is an amplifier, and 9 is a magnetic head. Is a recording circuit, and 10 is a data memory. The same components as those in the conventional example are designated by the same reference numerals. In a magnetic card insertion type manual magnetic card reader / writer, a columnar member 3 that is movable vertically to the insertion direction of a magnetic card 2 is arranged in a magnetic card traveling path 1. The columnar member 3 is pressed against the bottom surface of the magnetic card traveling path 1, and when the magnetic card 2 is inserted, the cylindrical member 3 rotates following the movement of the magnetic card 2. Further, the columnar member 3 operates as a shutter that shuts off the magnetic card running path 1 from the outside when the magnetic card 2 is not inserted. On the outer surface of the columnar member 3, a columnar magnetic body 5 on which a signal having the same density as the magnetic recording density to be recorded by the magnetic head 4 is recorded, and a magnetic head 6 for reading the signal recorded on the magnetic body 5 is provided. .. The signal detected by the magnetic head 6 is used as a clock signal for recording information on the magnetic stripe 7 formed on the magnetic card 2 by the magnetic head 4. The actual operation will be described below with reference to FIGS. 2 and 3. As shown in FIG. 2, before the magnetic card 2 is inserted, the columnar member 3 is in a state of being pressed against the bottom surface portion of the magnetic card traveling path 1. When the magnetic card 2 is inserted into the magnetic card insertion slot, the cylindrical member 3 is pushed up by the magnetic card 2 as shown in FIG. 3, and rotates in the direction of the arrow in FIG. 3 as the magnetic card 2 is inserted. The signal detected by the magnetic head 6 (the signal recorded in the magnetic body 5) by the rotation of the cylindrical member 3 is amplified by the amplifier 8 and becomes a clock signal, which is sent to the recording circuit 9 and the data memory 10, and the Data is recorded on the magnetic stripe 7 of the magnetic card 2 by the head 4. Also, instead of the magnetic head 6, a Hall element head or a magnetoresistive (MR) element head may be used as the magnetic sensing means.
