Note that the elevator 20 handles a plurality of magnetic cards 2 in one drive of the motor 23.
1. For example, it is raised by a height corresponding to the thickness of 10 sheets.

The magnetic card 21 is made of plastic,
For example, as shown in Figure 3, the width is 5.4 cm, the length is 6 cm,
It is formed into a rectangular thin plate shape with a thickness of about 0.5 mm, and on its surface are displayed numbers 21A for displaying the remaining call power, an arrow 21B indicating the insertion direction when using the card, a bar code 21C, etc. On the other hand, on the back side, a magnetic substance is applied across the front side, and a band-shaped diagonal area 21D indicated by a broken line constitutes a magnetic recording area, in which data for a predetermined number of calls, for example, 100 calls, is recorded. It's getting old.

The magnetic card storage section 2 is equipped with a door locking mechanism 35 other than the pair of locking devices 13 described above.
This is because the door 6
This is to prevent someone from opening the card and accidentally getting their hand caught in the elevator 20, and is rotatably disposed inside the magnetic card storage section 2 at the bottom when the elevator 20 is at the lowest position. , the elevator 20
A first rotating lever 36 that is rotated clockwise in FIG. 38, and a second rotating lever 39 having a lock portion 40 that rotates in conjunction with the raised rod 38, locks the door 6 when the rod 38 rises, and releases the lock when the rod 38 descends. It is structured as follows. The first rotating lever has a total of 3
The rollers 42a to 42c are provided on one of which the lower end of the thrust rod 38 is placed. The projecting rod 38 is guided and held so as to be vertically movable by a pair of guide members 43a and 43b disposed on the outer surface of the side plate 5A, and its upper end is connected to the second
The roller 44 provided on the rotating lever 39 is in contact with the roller 44 from below. The second rotary lever 39 is given a return behavior in the counterclockwise direction in FIG. 2 by a spring 45. On the other hand, the plate 10 of the door 6
An engaging member 47 having a pin 46 with which the lock portion 40 of the second rotating lever 39 engages is fixed to the back surface of the lever. Note that 50 is a detection device that detects whether the door 6 is closed.

The card take-in mechanism 30 is disposed above the inside of the magnetic card storage section 2, and is for sequentially feeding the magnetic cards 21 into the magnetic card writing device 1, and includes, for example, five rollers 55a to 55e and an endless belt 56. The endless belt 56 is configured to be driven by a motor to run in the card receiving direction (direction of arrow 57 in FIG. 1).
Further, one roller 55b among the five rollers 55a to 55e is arranged to be movable up and down, and is pressed into contact with the uppermost magnetic card 21 placed on the elevator 20 via an endless belt 56. A slit-shaped card intake opening 59 for receiving the magnetic card 21 is provided at the upper part of the side plate 5B.

A card height detection mechanism 60 is further disposed inside and above the magnetic card storage section 2 . This card height detection mechanism 60 is for detecting the uppermost magnetic card 21 and controlling the card loading mechanism 30 and the elevator lifting motor 23. Its configuration is shown in FIGS. 1, 4 and 4. To explain in detail based on FIG. 5, the topmost magnetic card 2
1a (FIG. 5) with a predetermined time difference.

The first card detection device 61 is rotatably disposed via a shaft 63 and has a spring 66 (see FIG. 1).
A sensor 67 consisting of a lever 64 which is given a clockwise rotation habit in FIG.
The lever 64 is provided with a roller 65 that presses against the magnetic card 21, and a light shielding portion 69 that blocks light from the light emitting element 67a.
Further, the roller 65 is connected to the recess 1 of the elevator 20.
It corresponds to 9.

The second card detecting device 62 is disposed at the back of the first card detecting device 61 with almost the same configuration as the first card detecting device 61, and is given a rotational habit by a spring (not shown), so that the roller 71 A lever 70 having a light shielding part 72, and a sensor 73 including a light emitting element 73a and a light receiving element 73b are provided. In this case, the sensor 73 is disposed at a position one step lower than the sensor 63 of the first card detection device 61, and the mounting height deviation is set to be the same as the upward movement distance of the elevator 20 by one motor drive. be done.

The card take-in mechanism 30 is operated by AND of the card detection signals from the first and second card detection devices 61 and 62, and when all the magnetic cards 21 on the elevator 20 are taken in, the first card detection device 61 The roller 65 falls into the recess 19 of the elevator 20 and detects the absence of the magnetic card 21, and this detection signal is sent to the taking-in mechanism 30, thereby stopping the taking-in mechanism 30. On the other hand, the elevator lifting motor 23 is stopped by the AND of the card detection signals from the first and second card detection devices 61 and 62, and the ten magnetic cards 21 mentioned above are taken in by the card taking mechanism 30. When the first card detection device 61 stops detecting the magnetic card 21 following the second card detection device 62, it is configured to be driven again by the signal sent from the time detection device 61. . In other words, the elevator lifting motor 23 has 10 magnetic cards 2.
It is driven intermittently every time 1 is taken in.

Next, the card loading operation of the magnetic card writing device 1 having the above configuration will be explained.

When a large number of magnetic cards 21 are placed on the elevator 20 and the elevator lifting motor 23 is driven to move the elevator 20 upward, the uppermost magnetic card 21A passes through the first and second card detection devices 61 and 62. The rollers 65 and 71 push them up. Therefore, the levers 64 and 70 gradually rotate counterclockwise in FIG. 1 against the springs, and first, the light shielding part 69 of the lever 64 is inserted between the light emitting element 67a and the light receiving element 67b, and the light emitting element is By blocking the light from 67a, the first card detection device 61 detects the magnetic card 21 and sends it to the card taking mechanism 30. At this time, the second card detection device 62 does not detect the magnetic card 21 yet, so the card capture mechanism 30 is not activated. The elevator 20 carries 10 magnetic cards 2.
1, the light shielding part 72 of the lever 70 of the second card detection device 62 is inserted between the light emitting element 73a and the light receiving element 73b and blocks the light from the light emitting element 73a. The card detection device 62 of No. 2 detects the magnetic card 21 and sends this detection signal to the elevator lifting motor 23.
The motor 23 is temporarily stopped. Further, this detection signal is simultaneously sent to the card taking-in mechanism 30, and the taking-in mechanism 30 is activated by AND with the detection signal from the first card detection device 61. Therefore, the magnetic cards 21 are taken in one after another and their height gradually decreases. Therefore, the second card detection device 62 no longer detects the magnetic cards 21, and when ten cards are taken in, the first card detection device 61 no longer detects the magnetic cards 21.
Then, a signal is sent from this first card detection device 61, and a signal is sent to the elevator lifting motor 23.
start it again. Therefore, the motor 23
The elevator 20 is moved upward until the second card detecting device 62 detects the magnetic card 21 as described above, and by repeating this series of operations, the magnetic card 21 can be continuously taken in.

When all the magnetic cards 21 on the elevator 20 are taken in, the roller 65 of the first card detection device 61 falls into the recess 19 of the elevator 20, and the absence of the magnetic card 21 is detected. Based on this detection signal, first, the operation of the card loading mechanism 30 is stopped. On the other hand, the elevator 20 rises once, but as a result, the roller 71 of the second card detection device 62, which had already been restored, comes into contact with the upper end surface of the elevator and is further pushed up, causing the second card detection device 62 to rise. 62 operates again and sends out a detection signal. The detection signal from the second card detection device 62 causes the elevator 20 to stop rising, and at the same time descends to the initial lowest position and stops.

In the above embodiment, the heights of the sensors 67 and 73 are different, but the sensor 67 and 73 are set at the same height, and each lever 6
Of course, the heights of the light shielding parts 69 and 72 of 4 and 70 may be changed.

[Effect of idea]

As described above, according to the magnetic card writing device according to the present invention, the two types of card height detection devices are configured to limit the card taking in and elevator ascent and descent, and at the same time control the absence of the card. Therefore, the entire process from the time the magnetic card is placed in the device to the completion of writing can be performed fully automatically, which allows for labor savings and smooth and reliable operation. In addition, instead of installing a separate device to detect the absence of a magnetic card, it is also used as a height detection device to control elevator elevation and card loading, simplifying the structure and making maintenance and inspection easier. Become. In addition, the height detection device uses a non-contact switch consisting of a light-emitting and light-receiving element, so it is highly durable and can be used intermittently.
It has various effects such as being able to be used semi-permanently even if it is repeatedly turned on and off.
