Description

[Detailed Description of the Invention] The present invention relates to a passbook guide structure for a magnetic passbook reader that uses a guide to prevent a passbook inserted into a magnetic passbook passage from getting caught, and that prevents jitter errors from occurring due to the magnetic head and the guide colliding. .

Conventional magnetic passbook readers have passbook 4 as shown in Figure 1.
A magnetic head 7 records or reproduces information on a magnetic recording band 5 provided on the back side of the reader, and the reader is equipped with a printing section 8 that performs a printing operation on the back side of the magnetic passbook passage 3 from the recording or reproducing position. Many things are used. The area of the magnetic recording band 5 used for recording and reproducing information is not the entire width of the passbook;
One side (a) is provided close to the edge, and the other side (b) is provided approximately to the inside of the edge of the passbook.

The actual reader operation is often performed by sliding the magnetic head against the magnetic recording strip 5 while the passbook is stopped.

The magnetic head 7 is allowed to run along an elongated window hole 20 made in the bankbook passageway 3, and in order to make effective use of the area, the magnetic head 7 is run from the left side of the bankbook passageway in FIG. 1 and from the right side of the bankbook passageway in FIG. It is further opened to the right. The original position of the magnetic head 7 is shown in Figures 1 and 2 below the magnetic recording band 5 on the left side of the passbook passage, and it is hidden under the left side with the cam surface 21 to prevent it from hitting the passbook. be. When a magnetic passbook is inserted into the reader, it is inserted from below the passbook passage 3 in Fig. 1, and from the direction perpendicular to the paper surface in Fig. 2, and stops when the magnetic recording band 5 reaches the slot 20 position. However, the end of the bankbook may fall into the window hole, and if it falls, it will get caught or caught when the magnetic head 7 moves.

In order to prevent this problem, conventionally the second
As shown in the figure, a guide 22 was provided on the side opposite to the original position, biased to the left by a spring 23, and stopped at a stroke of 24. Therefore, when the passbook is inserted from the direction perpendicular to the paper surface and stopped as shown in Fig. 2, and the magnetic head is moved to the right, the magnetic head 7 comes into sliding contact with the magnetic recording band 5 of the passbook in the area A-A'. Information is recorded and reproduced using the guide 22, but if the vehicle hits the guide 22 while traveling, the impact causes jitter to worsen and errors are likely to occur.

In view of the above-mentioned drawbacks, this invention has the original position of the magnetic head outside the right side of the passbook passage, and prevents the passbook from falling by supporting only the vicinity of the corner of the passbook that passes through the original position side of the magnetic head when the magnetic head is in the original position. guide,
By supporting the magnetic head and providing it in a holder that runs in the direction of the window hole, it is possible to prevent the passbook from falling without making the device complicated or large, and to prevent any hindrance to the running of the magnetic head. The purpose of the present invention is to propose a passbook guide structure for a magnetic passbook reader in which the guide and guide run together to prevent jitters.

The present invention will be explained below with reference to illustrated embodiments.

3 and 4, in the magnetic passbook reader, a magnetic passbook passage 3 is formed by frame plates 1 and 2, and a window hole 6 is formed in the passbook passage below the magnetic recording band 5 into which the magnetic passbook 4 is inserted and stopped. has been done. The magnetic recording strip 5 is attached to the back of the bankbook, and a magnetic head 7 protruding from the window hole 6 and running in the direction of the hole slides into contact with the magnetic recording strip 5 to record or reproduce information. A printing section 8 is arranged at the back of the window hole 6 position of the passbook passage 3. A head guide plate 9 is attached around the tip of the magnetic head. The magnetic head 7 is provided on a holder 10 so as to be vertically movable and swingable, and is moved laterally by the rotation of a ball screw 11. Also, the fourth part of the holder 10
A passbook fall prevention guide 12 is fixed on the left side in the figure so as not to be able to swing.

The window hole 6 is formed in the passbook passage 3 in a direction perpendicular to the insertion direction of the magnetic passbook 4, and extends from the window hole part 6a inside the passbook passage 3 to the right side outside the passbook passage. It is composed of an extension part 6b.

The magnetic head 7 is mounted on a support plate 13 as shown in FIG.
One end of the support plate 13 is supported by the holder 10 in a vertically movable manner, and the spring 1
4, it is pressed and biased in the direction of the bankbook. The holder 10 is held by two guide rods 16, 16 attached to another frame plate 15 so as to be movable laterally. The spring 14 constitutes a pad pressure generating means.

The passbook fall prevention guide 12 is installed lower than the height of the tip of the magnetic head 7 in FIG.
The inclined surfaces 12a on both sides shown are extended downward in FIG. The head guide plate 9 has inclined surfaces 9a, 9a on both sides, but functionally, only the left side in FIG. 4 may be used.

The magnetic passbook reader is configured as described above, the magnetic passbook 4 is inserted into the passbook passage 3, and the magnetic recording strip 5 is inserted into the passbook passage 3.
When it advances to the window hole 6 position, insertion is stopped. At this time, the magnetic head 7 is in its original position below the extension 6b of the window hole 6 in FIGS. 3 and 4, and the passbook drop prevention guide 12 faces the window hole 6a in the passbook passage. Therefore, even if the end of the passbook 4 inserted into the passbook passage 3 tries to fall into the window hole 6, it is caught by the upper surface of the passbook fall prevention guide 12. Here, when the holder 10 is moved by the rotation of the ball screw 11,
The magnetic head 7 and the passbook fall prevention guide 12 are moved together, and the tip of the magnetic head 7 slips under the passbook 4 and comes into sliding contact with the magnetic recording band 5 for recording or reproduction. When the magnetic head 7 is moved to the left side in the figure, the passbook fall prevention guide 12 closes to the window hole 6a.
The magnetic head 7 returns to its original position together with the holder 10 by the reverse rotation of the ball screw 11. The magnetic bankbook 4 that has been recorded or reproduced moves forward, the printing section 8 performs necessary recording, and the magnetic bankbook 4 is returned to the insertion slot of the magnetic bankbook path.

As described above, the present invention provides a passbook fall prevention guide that supports only the vicinity of the corners of the passbook passing through the original position side of the magnetic head when the magnetic head is in the original position, and allows the magnetic head to move freely in the direction of the window hole. Since the guide is provided in a holder which is supported by the magnetic head, the guide can be small, so that even when the magnetic head is run, the guide does not protrude outward in the width direction of the device, and the device does not become large.

Also, do not connect the above guide directly to the magnetic head.
Since the magnetic head is attached to a holder that supports it so that it can swing freely, when the magnetic head is running, even if the guide and the passbook come into sliding contact, the vibration will not be transmitted to the magnetic head, and the swinging movement of the magnetic head will be prevented. It is possible to provide a passbook guide structure for a magnetic passbook reader that has effects such as being able to perform good recording and reproducing since it is not obstructed.
