Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a feeding mechanism used in a device for recording information on a record carrier and/or reproducing information recorded on a record carrier. In particular, improvement of record carriers used in devices that record and/or reproduce information by moving a card-shaped or sheet-shaped record carrier and a head section for processing information with respect to the record carrier relative to each other. Regarding the feeding mechanism.

The above information recording/reproducing device is suitably used as an optical information recording/reproducing device or a magnetic information recording/reproducing device.

[Background of the invention]

Conventionally, various types of record carriers, such as card-shaped, disc-shaped, and tape-shaped, have been known for recording information using a light beam and reproducing the recorded information using a light beam. It is being Among these, optical information recording carriers formed in the form of cards (hereinafter referred to as "optical cards") are expected to be in great demand as record carriers that are easy to manufacture, portable, and easily accessible. .

In an optical card, the information tracks are formed in a straight line, and a large number of such information tracks are arranged in parallel in a predetermined area on the card surface.

Therefore, in an information recording/reproducing device using an optical card as a record carrier, the light beam spot is continuously moved relative to the information track on the surface of the optical card, and at this time information is recorded or reproduced. After being moved a predetermined distance, the optical beam switch I is moved a predetermined distance relative to the direction of the information track on the surface of the optical card, and at this time, no information is recorded or reproduced. , and then again continuously moved relatively in the direction of the information track, at which time information is recorded or reproduced, and in the same manner, relative movement in the direction of the information track and relative movement in the direction across the direction The movements are alternately repeated a desired number of times.

In addition to the above, there is a read-only optical card that can copy recorded patterns in large quantities and at high speed using photolithography technology. This is A42 with a non-silver salt pattern layer between the base material and the protective layer.
It has a structure with a reflective film, and metal is deposited during electroless plating only in the areas exposed to light, which become recording bits and record information in two values: high reflectance areas and low reflectance areas. , the size of one bit is several microns to ten-odd microns. Normally, for high-speed playback, a line sensor such as a CCD is used to reproduce dozens of pits and hundreds of bits (one track) at a time.
Main scanning is performed, and sub-scanning is performed in a direction across the track.

After moving a predetermined distance, the reproducing head is moved a predetermined distance in the direction of the information track, and sub-scans again in a direction across the track. Thereafter, similarly, the direction across the information track and the relative movement in the direction of the information track are alternately repeated a desired number of times.

By the way, optical cards are generally made of flexible materials such as polycarbonate and vinyl chloride resin.

Since the optical card is manufactured using acrylic resin or the like, if various mechanical pressures and heat are applied during use, for example, during storage, the optical card will inevitably become warped or undulated after long-term use. When recording and reproducing information using an optical card modified in this manner, various inconveniences may occur.

This inconvenience means that the chief ray of the light beam emitted from the optical head does not return to the optical head normally due to the undulation of the optical card, or if the optical card is used only for playback, the information track of the optical card is displayed on the CCD line sensor. The problem is that the image is blurred on one side or the image is not formed properly.

In addition, the information recording section with the above-mentioned information track has a part that indicates the beginning and end of information, and it is possible to detect this and reverse the card feeding direction.
information must be sensed and processed to determine the beginning and ending signals. Furthermore, this type of discrimination can be performed using ECC.
(Error correction code) is included in the process, it takes approximately 500m5ec from detection to determination, which has drawbacks such as increased access time and the card becoming detached from the feeding mechanism due to overfeeding of the card. .

[Summary of the invention]

In order to achieve the above object, the information recording carrier feeding mechanism according to the present invention has a first area that includes the carrier end along the feeding direction and is adjacent to the first area where information is not recorded. a card-shaped information recording carrier having a second area;
A feeding mechanism that moves relative to the information recording and/or reproducing head, the driving roller for moving the information recording carrier and the driving roller contacting the opposite side of the information recording carrier, and the driving roller is in contact with the opposite side of the information recording carrier. a pair of pressing members that press the carrier, the information recording carrier is sandwiched and fed between the driving roller and the pressing member, and the distance between the driving roller and one of the suppressing members in the feeding direction is set to a1. It is characterized by satisfying the relationship a≦b, where b is the width of region 1 in the feeding direction.

Furthermore, specifically, the pair of pressing members are located at positions equidistant a apart from each other about the center of rotation of the drive roller, and the pair of pressing members and the drive roller forcefully bend the card-shaped information recording carrier. let This makes it possible to reduce malfunctions in information recording and reproduction caused by deformation of the information recording carrier.

Further, by designing the information recording carrier to satisfy the above-mentioned relationship a≦b, the information recording carrier will not be separated from the feeding mechanism when the information recording carrier is sent.

〔Example〕

Here, we will take an information reproducing device using a reproducing-only optical card as an example.
The feeding mechanism of the present invention will be explained.

Reference numeral 2 indicates an illumination light source such as an LED, and reference numeral 3 indicates an illumination optical system for focusing the light emitted from the illumination light source 2 onto the information recording surface 4a of the optical card 4.

When an LED is used as the illumination light source 2, the light emitting part of the LED usually has a size of about several hundred microns, so the light emitting part can be regarded as a substantially uniform surface light source. Therefore, by establishing an appropriate optical relationship between the illumination light source 2 and the information recording surface 4a using the illumination optical system 3, a certain area of the information recording surface 4a of the optical card 4 (i.e., containing a plurality of pieces of information or information tracks) can be formed. area) can be illuminated. The information recording surface 4a thus illuminated is imaged by an imaging optical system 5 via a reflecting mirror 6 onto a line sensor 7 such as a COD. Light receiving elements are arranged on the information recording surface 4a.
Information on optically corresponding parts of the image is sequentially scanned (main scan) and converted into electrical signals.

Reference numeral 8 denotes a card insertion detection sensor for detecting that the optical card 4 is inserted into the information reproducing device 100 and driving the motor 9 based on the detection signal. The light from this sensor 8 is projected perpendicularly onto the optical card 4, and the motor 9 transmits its rotational force to a drive roller gear 11 via a reduction gear 10, and a drive roller 12 connected to this drive roller gear 11. to drive. On the other hand, the rotational force of the driving roller gear 11 is transmitted to the loading roller gear 16 through the idler gears 13, 14 and 15, and drives the loading roller 17 connected to the loading roller gear 16.

．． Reference numerals 22 and 23 indicate presser pieces, with the drive roller 12 being sandwiched between the presser pieces 20, 21 and 22, respectively. 2
．． 3 is parallel to the drive roller. Further, the distance between the driving roller 12 and the optical card 4 in the thickness direction is made narrower than the thickness of the optical card 4, and the optical card 4 is arranged at a position where the optical card 4 is forcibly curved with respect to the card feeding direction.

Moreover, the distance between the center of the drive roller 12 and the center of the presser piece 19 is set to be smaller than or equal to the distance between the end of the optical card 4 and the information record #4a. It is rotatably fixed to the card feeding body so as to be located outside the information recording surface 4a when the card is fed.

Reference numeral 24 denotes a guide rail, and an inner surface 24a of the guide rail 24 is a sliding surface of the reference end 4b of the optical card 4, and serves as a reference surface for the feeding guide of the optical card 4. Also, guide rail 2

A slope 24b is provided with a slope in a direction perpendicular to the Y direction. At both ends of the guide rail 24 in the card feeding direction, there are sensors 25 for reversing the card feeding direction. 26
is located next door. This sensor 25,26 is the optical card 4
When detected, an inversion signal is sent to a controller (not shown) of the playback device 100.

A leaf spring 27 urges the optical card 4 toward the guide rail 24 at a position where the optical card 4 is slightly separated from the loading roller 17. 28 is also a leaf spring, which urges the optical card 4 toward the guide rail 24, and when the optical card 4 is in a position where information can be reproduced with respect to the reproducing head l, it biases the optical card 4 toward the guide rail 24. It is placed in a position where it is always energized.

FIG. 2 is a plan view of the optical card 4. As mentioned above, 4a is the information recording surface of the optical card 4, and 4a' is the non-information recording surface. Information is recorded on the information recording surface 4a in the form of two symbols, a high reflectance area and a low reflectance area. optical card 4
4a' is the presser foot 21. The non-information recording surface 4a' in the lower part has a width (in the X direction) slightly larger than 22.
has a slightly larger width (in the X direction) than the presser pieces 20 and 23 and the drive pinch roller 19. On the other hand, the left and right sides of the optical card 4 in the Y direction in the figure are shown.

Note that 4b is a reference end of the optical card 4, on which binary information is patterned and slides on the reference surface 24a of the guide rail 24. 4c is leaf spring 2

As mentioned above, b' satisfies the relationships a≦b and a≦b', where a is the distance between the center of the drive roller 12 of the feeding mechanism shown in FIG. 1 and the center of the presser piece 19.

FIGS. 3(A) to 3(F) show the information reproducing device 10 shown in FIG.
FIG. 2 is a sectional view of the main part of 0, viewed from the direction of arrow A in the figure.

FIG. 1 is an explanation of the operation of the feeding mechanism according to the present embodiment.

This will be explained in detail using FIGS. 2 and 3. In FIG. 3, reference numeral 29 indicates an insertion slot for the optical card 4 of the information reproducing device 100, and the same member as that shown in FIG.
Components are designated by the same reference numerals as those in the figure, and description thereof will be omitted here.

Moreover, each of FIGS. 3(A) to 3(F) shows the feeding state of the optical card 4 at each time when the optical card 4 is inserted and after insertion, and parts unnecessary for the explanation are omitted for convenience. ing.

FIG. 3(A) shows the optical guard being inserted. When the light guide 4 passes through the insertion slot 29 and card insertion is detected by the card insertion detection sensor 8, a controller (not shown) is activated based on the detection signal. drives the motor 9.

The rotational force of the motor 9 is transmitted through a reduction gear 10 and a roller drive gear 1.
1 to rotate the drive roller 12 through the idler gear 13. 14. 150-Rotate the loading roller 17 in the CW force direction in the figure via the turning roller gear 16. By further inserting the optical card 4 in the direction of the arrow Y, the optical card 4 is sandwiched between the loading roller 17 and the loading pinch roller 18 and starts loading in the direction of the arrow. At this time, as shown in FIG. 1, the loading pinch roller 18 drives only the side opposite to the reference end 4b of the optical card 4, so that the tip of the optical card 4 faces left in FIG. Rotate (in Figure 3, perpendicular to the page,
and the direction facing the paper). Then, while the left end of the optical card 4 is sliding on the sliding surface 24a of the kite rail 24, and the back surface of the optical card 4 is sliding on the slope 24b of the guide rail 24 (
(The inclination of the slope will be explained later)
It is loaded onto the drive roller 12 as shown in B).

Next, the optical card 4 is connected to the driving roller 12 and the driving pinch roller 1.
9 and is loaded. At this time light card 4
Since the sliding surface 4C of is biased in the X direction in FIG. 1 by the leaf spring 27, the rear side of the reference end 4b of the optical card 4 is also pressed against the sliding surface 24a (reference surface) of the guide rail 24. Therefore, the reference end 4b of the optical card 4 is completely parallel to the sliding surface 24a of the guide rail 24, and the presser piece 22.2
Sent to 3.

Next, when the optical card 4 is engaged with the presser pieces 22, 23, the optical card 4 is forcibly bent by the presser pieces 20, 21, 22° 23 and the drive roller 12. Korak minutes (
A surface with sufficient flatness can be created with a thickness of several microns to more than ten microns. The rear end of the optical card 4 is separated from the slope 24b of the guide rail 24, and the optical card 4 and the slope 24b are almost parallel to each other. In this state, information can be reproduced from the information recording surface 4a by the reproducing head 1, and the optical card 4 is sub-scanned in the direction of the arrow Y. The information recording surface 4a is located on the upper surface of the drive roller until the optical card 4 leaves the presser frame 20, 21, and this area becomes the sub-scanning range. (See Figure 3 (C) and (D)) Next, Y
When the sub-scanning in the direction is completed and the information of the l band is reproduced, the reproduction head 4 is sent to the adjacent track. or,
The optical card 4 is further fed in the Y direction, and when detected by the card feed reversal sensor 26, the rotation direction of the motor 9 is reversed in response to a detection signal. (See Figure 3 (E)) The optical card 4 is returned to the insertion slot 29 side by the reversal of the motor 9, and when detected by the optical card 4 feed reversal sensor 25, the optical card 4 is reversed again by the detection signal, and the above-mentioned By repeating the sending and reproducing operations a predetermined number of times, it is possible to reproduce all the information on the optical card 4.

Next, when the optical card 4 is to be ejected from the playback device 100, the rotation of the motor 9 is reversed and the process opposite to that of loading is performed. (See Figure 3 (F)) During the above feeding operation, the optical card feeding reversal sensor 25°26
When the end of the optical card 4 is detected in
1 or held by the presser pieces 22 and 23. Further, in this state, information is not recorded and/or reproduced.

The reversal sensors 25 and 26 are composed of a pair of light emitting elements and light receiving elements called photo ink converters, and the end of the optical card 4 blocks the light being projected from the light emitting element to the light receiving element. By this, the edge of the optical card 4 is detected. The end of this optical card 4 has the second [9i: Indicating non-information M
□ Recording reduction 48.7, information 8 □ The pattern existing at the end of the recording head 1 is not read by the reproducing head l (the feeding direction is simply reversed by the signals from the reversing sensors 25 and 26.

Next, how much forced curvature of the optical card 4 is required?
We will discuss how the optical card 4 moves as a result of this. There is no standard for the optical card 4 regarding its warpage 1, and here we will discuss JISB9560 (
This explanation uses the standard for credit cards with magnetic stripes.

According to JIS, the maximum amount of warp when a card is placed on a flat surface is 2.
It is set as mm. Here, as shown in Fig. 4, the maximum warp is $ > 2 m at a constant R in the longitudinal direction of the a' card.
In order to forcibly bend a card with a longitudinal dimension f=85.6 when warped by m, it is necessary to bend the card by an amount equal to or more than the warp amount.

FIG. 5 shows rollers 50 and 51. 5 is a diagram in which an optical card 48 is forcibly bent by three rollers 50, 51, and 52 with a distance of a between them. Such a roller 50°51,5
2, the optical card 4 is transported by three rollers 50.2 due to the elasticity of the optical card 4. Rather than contacting rollers 51 and 52 at one point, each roller 5
0.51.52, but in order to make the explanation easier to understand, the optical card 4 is bent at one point (the center of the drive roller 50), and the rest is straight and there are two The optical card 4 is in contact with the rollers 51 and 52.
shall be sent. The difference between the amount of warpage at a position a' apart from the center of the optical card 4 in FIG. 4 and the maximum warp quantum is d in FIG.
The warp angle of the card when it is forcibly bent is the value of jan
−'−21 can be found.

If the radius of curvature of the card is R and the thickness of the card is t in the case of the amount of warpage of the optical card 40 in FIG. =0.74 a=2 b=85.
When adding 6 = 10, it becomes d = 6.87 x 10-10-2 (tan-'d/z# 0.4°.

From the above, the light guard 4 with a maximum warping amount of 2 mm is placed at a roller interval a.
= 10 mm To forcefully bend the optical card 4 with the roller 50, 51, 52, bend the optical card 4 by 0.07 mm or more.
It can be seen that there is a need to tilt the blade at an angle of approximately 0.4°.

By the above method, the slope 24b of the guide rail 24 can be used to determine the area that does not come into contact with the optical card 4 during information recording or reproduction of the optical card 4, and to facilitate smooth insertion and ejection.
You can see the shape of.

Also, by increasing the roller interval a, the optical card 4
Even if the deflection fid varies, the amount of deflection of the tip of the optical card 4 can be reduced. Increasing the distance a between the scroll rollers narrows the information recording section 4a of the optical card 4, thereby reducing the amount of information recorded on the optical card 4.

A method for determining an appropriate amount of distance a will be described below.

In FIG. 5, an optical card, 4
Consider the case where one end of the two is in contact. Here, the distance a between the presser rollers 51 and 52 and the drive roller 50 is set to approximately 0 in the range.
, 2 rn m, and the amount of deflection d is d=o, L~0.
Set it to 3. At this time, variation in the amount of deflection d' of the other end of the optical card 4 that is not in contact with the presser rollers 51 and 52;
In other words, find the value of d' when d=0.1 and the value of d' when d=o,3, and calculate the difference between these two values using a general-purpose photo ink converter (sensor 25, 26). Considering the width of the optical card and the thickness of the optical card, and setting the limit to approximately 2 mm, the roller spacing a at this time is determined. This at
,! When the value of ヰ is calculated based on each of the above formulas, the value of ヰ is 9.5 mm.
Therefore, it can be seen that the appropriate roller spacing a is generally about 9.5 to 12 mm, taking into account the accuracy and amount of information of the photo ink club or deflection fid.

The driving roller 50 and presser roller 51゜5 are removed in the above manner.
2 and both rollers 50. By arranging 51 and 52, not only accurate information reproduction and information recording can be achieved by appropriately forcibly bending the optical card 4, but also the amount of information on the optical card 4 can be set to the maximum.

Also, the width of the non-information recording section 4a' in the optical card 4 is as follows.

Since the relationship between b' and the interval a is set such that a≦b' and a≦b, all the information tracks of the information recording section 4a are read under the same conditions, and the signal for reversing the card feed is transmitted to the optical card 4. This can be achieved by detecting the end portion of, for example, the non-information recording portion 4a' with the sensor 25, 26, so that a high-speed feeding operation can be achieved.

Next, consider the sub-scanning speed. If the information bits in one track of the optical card are 10 [μm] and one track is sampled twice at a sampling time of lOO [μ5ec], the sub-scanning speed in the Y direction of the optical card 4 is l0X10-3/100XIO. -'X2=50Cc m
/sec).

At this speed, the time required for the optical card 4 to become 10 mm heavier is 10 mm 150 cm/5 ec==0.2 (sec
), detecting the beginning or end of the information recording area,
and processing and discrimination, at least 0.2 seconds
It takes more time. Therefore, access time can be shortened by directly detecting the end of the optical card 4 rather than by detecting the end or beginning of the recording area of the optical card 4.

In the above embodiment, an optical card for reproduction only was used as the information recording carrier, but the card-shaped information recording carrier to be moved by the main feeding mechanism is not limited to this type of optical card. Various record carriers are applied, such as possible optical cards, magnetic cards, etc.

Of course, the information reproducing/recording device provided with the main feed mechanism is not limited to the form of the above-mentioned embodiments, and may be of various forms.

In the embodiment described above, a sensor 2 consisting of a photoelectric sensor such as a photo ink printer detects the reversal of the feeding direction of the optical card 4.
Although 5.26 is used, the same effect can be achieved by using a mechanical leaf switch. However, whether it is a photoelectric sensor or a leaf switch, there is a good chance that it will malfunction due to dust, disconnection, etc. Therefore, the relationship between a and b above is set as a#b, and the detection of the beginning and end of the information recording section 4a and the card end detection are used together, and by reversing the card feeding direction by detecting at least one of them, one of the Even if the detection means causes trouble, the trouble can be avoided by using the other detection means.

In addition, in case a problem occurs with both detection means, by providing a means to drive the gear train from the outside or by providing a member to directly pull out the card,
It is possible to prevent bigger problems from occurring.

〔Effect of the invention〕

As described above, according to the information recording carrier feeding mechanism according to the present invention,
The information recording carrier is held and fed by a drive roller and a pair of pressing members, and the distance a between the center of the driving roller and the pressing member is
By making the width of the information recording carrier less than or equal to the width of the non-information recording portion of the information recording carrier, information can be accurately reproduced and recorded from the information recording carrier, and the information recording carrier can be moved back and forth stably. We can provide a feeding mechanism.

Furthermore, when the information recording carrier is being fed, a reversing sensor is provided to detect the end of the information recording carrier, and by reversing the feeding direction of the information recording carrier based on the output from this sensor, it is possible to prevent the information recording carrier from being over fed. It is also possible to prevent this and perform a high-speed reversal operation.
