Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a card reading device that detects the reading position of a card inserted into an insertion slot and can reliably read the card.

Conventionally, in card reading devices that read information recorded on cards through punch holes or marks, etc., it is necessary to manually insert the card into the insertion slot.
In many cases, the information is read by dropping the device under its own weight and moving it to the reading position. This type of card reading device includes a set of reading sensors as means for detecting the reading position.
Alternatively, a plurality of reading sensors are arranged in the same row and perpendicular to the card movement direction.

However, even if it detects that the card has reached the reading position and starts reading, if a slight vibration or someone pulls out the card during reading, the card may come off the reading sensor position due to this vibration. There was a fear that it would become unreadable. Therefore, there was a drawback that reading had to be stopped, the card had to be reinserted and read again, or the card had to be rendered unreadable. Furthermore, since the amount of deviation of the card from the reading position is unclear, improvements have been desired.

The present invention was developed in view of the above circumstances, and its purpose is to generate a card reading position signal when the inserted card reaches a reading position with sufficient margin, although it has a relatively simple configuration. Provided is a card reading device having a reading position detection function that detects whether or not the reading sensor is located within the permissible limit necessary for reading even if the card position is subsequently moved and whether or not the information on the card can be read. That is.

The present invention will be explained below based on an embodiment shown in FIGS. 1 to 4. Fig. 1 shows an example of a card reading device with a built-in card reader, and an insertion slot 12 for a card reader 10 into which a card a is inserted is protruded from the upper part of the housing 1, and a slot 12 is provided nearby. power lamp 3 on the displayed display board 2
When the insertable lamp 4 is lit, insertion of the card a is permitted. Note that 5 is a drawer-type storage box that is provided at the front of the housing 1 and stores punch waste (not shown) that has been punched after being read by the card reader 10.

Further, a storage section 6 is formed at the rear of the casing 1 so that the punched card a can be stored in the casing 1 in an upright position.

Next, FIGS. 2 and 3 are a perspective view and a longitudinal sectional view of the card reader 10. In the drawings, the card reader 10 has an insertion opening 12 formed in the upper part of a guide body 11 that guides the insertion of the card a, and a positioning member 13 for locking the tip of the inserted card a is attached to the lower part. ing. Further, the opposing wall 1 of the guide body 11
1a and 11b have slits 14-1, 14-2, and 14- in the direction perpendicular to the card a to be inserted, respectively.
3,14-4 and 15-1,15-2,15-
3, 15-4 are facing and drilled. However, one slit 14-1, 14-2, 14-
There are floodlight lamps 1 on the outside of 3 and 14-4, respectively.
6-1, 16-2, 16-3, 16-4 are arranged adjacent to each other, and the other slit 15-1,
Reading photoelectric conversion elements 17-1, 17-2, 17-3, 1 are provided on the outside of 15-2, 15-3, 15-4.
7-4 are arranged adjacent to each other, and the above-mentioned floodlight lamp 1
6-1, 16-2, 16-3, 16-4 and photoelectric conversion elements 17-1, 17-2, 17-3, 17
-4 are covered with covers 18 and 19, respectively, forming a so-called punch card reading sensor block 20.

Further, in the lower part of the guide body 11, slits 21-1, 21-2 and 22-1, 22-2 are formed facing each other in both side walls in order to detect the lower end of the inserted card a. one slit 2
Projecting lamps 23-1 and 23-2 are arranged adjacent to each other on the outside of the slits 1-1 and 21-2, respectively, and photoelectric conversion for reading position detection is arranged on the outside of the other slit 22-1 and 22-2. Elements 24-1, 24-2
are arranged adjacent to each other, and the projection lamp 23-
1, 23-2 and photoelectric conversion elements 24-1, 24
-2 covered with covers 25 and 26, respectively, so-called reading position detection sensor block 27
is formed. Here, one photoelectric conversion element 24-1 is for detecting the minimum amount of cards inserted, and the other photoelectric conversion element 24-2 is for detecting the maximum amount of cards inserted.

Therefore, the photoelectric conversion elements 24-1, 24-
2 is constructed so that when at least one of them detects the reading position, a detection signal is sent to the flip-flop 28, and a signal indicating that the card can be read is generated. Note that FIG. 4 is a perspective view of a punched card a showing an example of a card inserted into this device, and 29 is an information punch hole punched on the card a.

Here, the reading photoelectric conversion elements 17-1, 17-2, 17-3, and 17-4 of the punched hole 29 are each set relative to the outer diameter dimension D of the punched hole 29 punched on the card a. Extremely small slit 14-1
... and 15-1... limit the incident light, and a photoelectric conversion element 24- for detecting the reading position.
1, 24-2 also has the outer diameter dimension D of the punch hole 29.
The incident light is limited by the slits 21-1, 21-2 and 22-1, 22-2, which are smaller than the slits. Furthermore, the photoelectric conversion elements 24-1, 24
The interval d of -2 is set to a value that is equal to or smaller than the outer diameter dimension D of the punch hole 29.

Next, the operation of the present invention based on the above configuration will be explained. 1 to 3, the punch card a is now inserted from the insertion opening 12 along both side walls of the guide body 11 in the direction indicated by the arrow. and,
When the card a is inserted to a position where the lower end thereof contacts the positioning member 13, the photoelectric conversion elements 24-1 and 24-2 are blocked by the card a and a readable signal is emitted from the flip-flop 28, so that data (not shown) is inserted. The reading control circuit includes punch hole reading photoelectric conversion elements 17-1, 17-2, 17- arranged in the reading sensor block 20.
3, 17-4 can be read.

Here, after the readable signal is generated, even if the card a moves in the direction of the insertion slot 12 as shown by the dashed line, the sensor detects the minimum insertion amount, that is, the photoelectric conversion element 24.
It becomes possible to continue outputting a readable signal until it deviates from -1 and is no longer blocked.

Moreover, since the distance d between the photoelectric conversion elements 24-1 and 24-2 is set to be the same as or a smaller value than the outer diameter D of the punch hole 29, the movement of the card a is controlled by the punch hole 29 on the card. Information can be read accurately up to the determined permissible limit of the reading position, that is, the interval d.

As explained above, according to the present invention, when a card is manually inserted from the insertion slot or dropped by its own weight, the activation time of the photoelectric conversion element is much faster than when the card bounces mechanically. This has the advantage that even if the card is manually pulled out, it can be read reliably, and there is no need to wait until the card bounces or the like stops. Furthermore, since the reading position is detected using two photoelectric conversion elements, it has superior effects such as being able to prevent deviations in the detection position caused by dust etc. compared to the case where the reading position is detected using one photoelectric conversion element. It is something that plays.
