Abstract

PURPOSE:To easily exchange a cleaning roll with a simple mechanism by moving a member, which supports the cleaning roller, in a rotary shaft direction and freely executing the attachment and detachment of the cleaning roller. CONSTITUTION:A handle 36 is moved in an X direction and a cleaning roller 25 is moved in the X direction. Then, when the cleaning roller 25 is pulled out from a transmitting shaft 31, the cleaning roller 25 is moved in this side and detached since the cleaning roller 25 is canceled from the engagement of a leading-in shaft 33 and the transmitting shaft 31. When the cleaning roller is attached, the handle 36 is moved in the X direction and the cleaning roller 25 is positioned between the transmitting shaft 31 and leading-in shaft 33. Then, the leading-in shaft 33 and transmitting shaft 31 are fitted to a round hole 39 of the cleaning roller 25 and the cleaning roller 25 is rotated. After that, a long hole 39a of the cleaning roller 25 is fitted to a pin 32. Thus, when the handle 36 is moved, only the cleaning roller 25 can be easily taken out and exchanged. Accordingly, the cleaning roller can be easily exchanged and the mechanism can be made simple.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording/reproducing device for a card-shaped information recording medium, which has a cleaning mechanism for removing dust, dirt, etc. adhering to the card.

[Conventional technology]

Some of the conventional recording and reproducing devices for card-shaped information recording media have been proposed to be equipped with a cleaning device to prevent dust, dirt, etc. adhering to the card from making it impossible to accurately record or reproduce information. has been done. moreover,
In preparation for the cleaning device being used for a long time and reaching the end of its life, a detachable cleaning device is disclosed in Japanese Patent Laid-Open No. 61-280086.

Further, a dedicated device for cleaning cards has been proposed, and is disclosed, for example, in Japanese Patent Application Laid-Open No. 62-287494.

Figures 11 and 12' are perspective views of the conventional device;
is a recording/reproducing device, and 61.62 is a cleaning device.

[Problem to be solved by the invention]

However, if the cleaning device is provided separately from the recording and reproducing device for card-shaped information recording media, the user must first clean the card with the cleaning device and then insert the card into the recording and reproducing device for processing. However, it has drawbacks such as being extremely troublesome and time-consuming to use. Therefore, if a cleaning device is built into the recording and reproducing device, the card will be automatically cleaned, making it convenient to use. On the other hand, in a cleaning method in which dust, dirt, etc. on a card is transferred to a cleaning member, the cleaning member gradually becomes less effective in cleaning dirt when used for a long time. Therefore, it becomes necessary to replace the dirty cleaning member with a new one. However, if the entire cleaning device is replaced in order to facilitate replacement, the mechanism becomes complicated, resulting in increased cost and the procedure for replacement becomes complicated.

The present invention is proposed to solve the above problems,
It is an object of the present invention to provide a recording and reproducing device for a card-shaped information recording medium in which a part of the cleaning device can be easily attached and detached.

[Means and operations for solving the problems] In order to achieve the above object, the present invention includes means for cleaning the surface of a card-shaped information recording medium while being held between a rotating cleaning roller and a card driving roller. In a recording/reproducing device for a card-shaped information recording medium, the cleaning roller is made detachable by making a member that rotatably supports the cleaning roller movable in the direction of the rotation axis.

Since the cleaning roller support section is thus made movable, only the cleaning roller of the card cleaning device can be easily attached and detached.

〔Example〕

FIG. 1 is a schematic perspective view showing a first embodiment of the present invention. This embodiment is applied to an optical card recording/reproducing device. In FIG. 1, 1 is a shuttle, which is a stand on which an optical card 2 is placed. The optical card 2 is divided into a recording section 2a where data is recorded and a non-recording section 2b where data is not recorded. On the shuttle l, the optical card 2 is biased in the Y direction by a spring pushing up the push-up plate 3, and the left collar 4
, is pressed against the right collar 5. Left brim 4, right brim 5
covers the non-recording portion 2b of the optical card 2. A bent portion 3a is formed on the Z' side of the push-up plate 3, and serves as a guide when the optical card 2 is inserted into the shuttle 1. A left abutment part 4L is formed as a guide on the Z side of the left collar 4, and a right abutment part 5a is formed as a guide on the Z side of the right collar 5.

The notch 5b on the Z' side of the right collar 5 is a relief range for the rear rubber roller 6. A guide holder A7, a guide holder B8, and a guide holder C9 are integrally attached to the shuttle 1. Further, a bearing AIO is press-fitted into the guide holder ^7, a bearing Bll is press-fitted into the guide holder B8, and a bearing C12 is press-fitted into the guide holder C9. The bearing AIO and the bearing 811 slide along the right guide shaft 13 in the Z direction. Bearing C12 is X
It is an elongated hole in the direction, and slides in the Z direction along the left guide shaft 14. Further, an elongated lock hole 15 is formed in the upper surface of the guide holder A7 in the X direction. Lock hole 15
is formed so that the lock pin 16 is fitted,
When fitted, the shuttle 1 cannot move in the Z direction. The lock pin 16 is attached to the lock member 17,
The locking member 17 is attached to the pressing member 18. Further, a rear rubber roller 6 is attached to the pressing member 18. The pressing member 18 rotates around a rotating shaft B19 as a fulcrum. A portion of the pressing member 18 is connected to the iron core 21 of the solenoid 20.

An opposing roller 22 is located below the rear rubber roller 6, and when the rear rubber roller 6 approaches, the rear rubber roller 6
and the opposing roller 22 until the gap between the optical card 2 and the opposing roller 22 becomes less than the thickness of the optical card 2. Even if the shuttle 1 moves in the Z' force direction, the rear rubber roller 6 and the lock pin 16 come into contact with the right collar 5 on the shuttle l and the optical card 2 placed on the shuttle 1. Move away to a position where it does not occur. Further, the opposing roller 22 is located at a position where it does not come into contact with the optical card 2 placed on the shuttle 1. The sensor A23 is positioned slightly in the Z' force direction of the solder from the Z' side end surface of the left collar 4 when the lock pin 16 is fitted into the lock hole 15 and the shuttle 1 is movable in the Z direction.

A front rubber roller 24 is located in front of the opposing roller 22, and the width of the front rubber roller 24 in the X direction is approximately the same as the width of the optical card 20. A cleaning roller 25 is located above the front rubber roller 24 to wipe off dust, dirt, etc. adhering to the optical card 2.

The gap between the front rubber roller 24 and the cleaning roller 25 is set to be less than the thickness of the optical card 2. Front rubber roller 2
4 is rotated by a drive means (not shown) to transport the optical card 2. Further, the front rubber roller 24 is biased in the Y direction by a spring (not shown). A shutter 26 is located in front of the front rubber roller 24 and the cleaning roller 25 (in the Z' direction) and is rotatable around a rotation axis A27. The inserted optical card 2 is restricted from being inserted into the interior from this position, and is opened and closed by a shutter drive means (not shown).The shutter 26 is opened and closed by a sensor 829 located between the shutter 26 and the card guide 28. This is done by turning ON and OFF.

The card guide 28, sensor B29, shutter 26, rotating shaft A27, etc. are attached to the front panel 40.

Figure 2 is a partially enlarged view of the vicinity of the cleaning roller.
2 is a view seen from the Z' force direction in FIG. 1. FIG. Figure 3 shows
FIG. 3 is a perspective view of a cleaning roller.

The transmission shaft 31 is fitted into a round hole 39 formed in the end face of the cleaning roller 25, and the bottle 32 press-fitted into the transmission shaft 31 is fitted into an elongated hole 39a. The driving force of the transmission shaft 31 is transmitted to the cleaning roller 25 via the bin 32. On the other side of the cleaning roller 25, a retraction shaft 33 is biased in the X' force direction by a push spring 34 provided within the holder 35. The retraction shaft 33 is movable within the cylinder of the holder 35 in the X direction. A knob 36 is attached to the retraction shaft 33, and the retraction shaft 33 can be moved by moving the knob 36 in the X direction. In addition, the holder 3 is arranged so that the knob 36 can be moved.
A long groove 37 is formed in 5.

A cleaning cloth 38 is placed around the outer periphery of the cleaning roller 25.
is wound in a spiral.

Next, the operation of this embodiment will be explained. First, to describe the process from inserting the optical card 2 into the device to taking it out, first, the shutter 26 is in a closed state, and even if the optical card 2 is inserted into the card guide 28 when the device is powered on. Even if the card is inserted, the shutter 26 is not opened, thereby preventing dirt, dust, etc. from entering the device from the card guide 28. The solenoid 20 is a self-holding solenoid that attracts the iron core 21.

The shuttle 1 is locked with a lock pin 16 fitted into a lock hole 15. The left brim 4 of shuttle 1 is sensor A
23 at the non-detection position.

Next, with the power of this device turned on, the user inserts the optical card 2 into the card guide 28 in the Z direction. When the leading end of the optical card 2 reaches the detection position of the sensor 829 and detection is performed, a shutter drive section (not shown) opens the shutter 26 in response to a command from the control section. Further, the front rubber roller 24 is rotated by driving a motor (not shown).
The rear rubber roller 6 rotates in the L direction, and the cleaning roller 25 rotates in the L direction. The peripheral speeds of the front rubber roller 24 and the rear rubber roller 22 are the same, and the peripheral speed of the cleaning roller 25 is faster than the peripheral speed of the front rubber roller 24 and the rear rubber roller 22. The optical card 2 that has passed through the sensor 829 passes through the open shutter 26 and passes through the front rubber roller 24.
and the cleaning roller 25, and is sent in the Z direction by the rotation of both rollers.

Since the friction coefficient on the front rubber roller 24 is larger than the friction coefficient on the cleaning roller 250,
The inserted optical card 2 is fed as the front rubber roller 240 rotates. Since the circumferential speed of the cleaning roller 25 is faster than the circumferential speed of the front rubber roller 24, the optical card 2 is fed while the surface of the optical card 20 is rubbed, and dust, dirt, etc. adhering to the optical card 2 are wiped off. Further, since the rotation direction of the cleaning roller 24 is the L direction, which is the direction in which the optical card 2 is drawn in, the optical card 2 is inserted smoothly.

When the optical card 2 fed by the front rubber roller 24 reaches the rear rubber roller 6, it is also conveyed by the rear rubber roller 6.

Since the iron core 21 of the solenoid 20 is in a suction state, the gap between the rear rubber roller 6 and the opposing roller 22 is less than the thickness of the optical card 2, and the optical card 2 is conveyed while being held between both rollers. The width of the cleaning roller 25 is approximately the width of the optical card 2.
Since the width is almost the same as the width of the optical card 2, not only the recording section 2a of the optical card 2 but also the non-recording section 2b is cleaned. Therefore, the entire area of the optical card is cleaned until the optical card 2 reaches the rear rubber roller 6.
will not become dirty. The optical card 2 conveyed by the front rubber roller 24 and the rear rubber roller 6 comes into contact with the bent portion 3a of the push-up plate 3, and is inserted into the shuttle 1 using this as a guide. When the rear end of the optical card 2 passes the front rubber roller 24, it is conveyed only by the rear rubber roller 6, and as it advances further, the front end of the optical card 2 hits the right abutment 4as and the right abutment 5a. Immediately before the optical card 2 hits the right abutting portion 4as and the right abutting portion 5a, the sensor A23 changes from a sensing state to a non-detecting state. When the optical card 2 is in contact with the left abutting portion 4a and the right abutting portion 5a, the Z-side end surface of the left collar 4 and the Z-side end surface of the optical card 2 are at the same position in the Z direction. When the sensor A23 enters a non-detecting state, a shutter drive unit (not shown) operates the shutter 26 according to a command from the control unit.
is closed, the drive of the motor (not shown) is stopped, the solenoid 20 is activated, the iron core 21 is opened, and the pressing member 18 is closed.
rotates in the M direction around the rotating shaft 819, and the lock pin 1
6 and rear rubber roller 6 move in the Y direction and separate.

Next, the shuttle 1 reciprocates in the Z direction on the right guide shaft 13 and the left guide shaft 14 by a drive means (not shown). During this time, light is emitted from an optical head section (not shown) to read and write information on the optical card 2. Further, during recording and reproduction, even if the optical card 2 is inserted from the card guide 28, the shutter 26 does not open and no further insertion is possible. After the recording/playback operation is completed, the shuttle l
moves to the Z′ side. When the optical card 2 placed on the shuttle 1 reaches the sensor A23, the sensor A23 detects it and the 20 solenoid is turned on according to a command from the control section.

Then, the iron core 21 is attracted, the pressing member 18 rotates in the anti-M direction, and the rear rubber roller 6 and lock pin 16 move in the Y direction. When the lock pin 16 moves in the Y' direction, it fits into the lock hole 15, and the shuttle l moves slightly in the Z direction, causing the optical card 2 to come out of the detection position of the sensor A23 and become locked in a non-detection state.

Next, by driving a motor (not shown), the front rubber roller 24 is rotated in the L direction, the rear rubber roller 6 is rotated in the R direction, and the cleaning roller 25 is rotated in the R direction. Further, a shutter drive section (not shown) opens the shutter 26. By driving the rear rubber roller 6, the optical card 2 is conveyed from the shuttle 1 in the Z' direction. When the optical card 2 reaches the front rubber roller 24, it is conveyed by the front rubber roller 24 and the rear rubber roller 6. While transporting optical card 2, sensor ^2
3 is in a detection state, and when the end of the optical card 2 reaches the sensor 23, the sensor 23 becomes a non-detection state. after that,
The motor (not shown) continues to drive for a certain period of time, and the optical card 2 is moved between the front rubber roller 24 and the cleaning roller 25.
The motor is released from the grip and the motor stops. Then, when the user pulls out the optical card 2 protruding from the card guide 28, the sensor B29 enters the non-detecting state. Then, a shutter drive section (not shown) closes the shutter 26 in response to a command from the control section. In this manner, a series of operations from insertion to ejection of the optical card 2 is performed.

When a large number of optical cards 2 are processed by such an optical card reading device, dust and dirt adhering to the surface of the optical card 20 gradually accumulates on the cleaning roller 25, and the cleaning roller 25 gets dirty and the cleaning effect is reduced. It's going to decline. Therefore, it is necessary to replace the cleaning roller 25 so that the cleaning effect does not drop below a certain level. Next, according to Fig. 4, the cleaning roller 2
5 will be explained below. First, the front panel 40 is removed to make the cleaning roller 25 removable. The cleaning section is in a state as shown in FIG. 4A. Move the knob 36 in the X direction (Fig. 4B)
). Next, the cleaning roller 25 is moved in the X direction and removed from the transmission shaft 31 (FIG. 4C). Then, the cleaning roller 25 is disengaged from the retraction shaft 33 and the transmission shaft 31, so the cleaning roller 25 is moved forward and removed. And knob 3
Remove the force applied in step 6 (Fig. 4 D). In this way, removal of the cleaning roller 25 is completed.

Next, a method for attaching the cleaning roller 25 will be explained according to FIG. The cleaning section is in a state as shown in FIG. 5A. First, move the knob 36 in the X direction. Then, the cleaning roller 25 is
1 and the retraction shaft 33 (FIG. 5B). Next, remove the force applied to the knob 36, and remove the pull shaft 33 and transmission shaft 3.
1 into the round hole 39 of the cleaning roller 25 (
Figure 5C). Next, rotate the cleaning roller 25 in the direction of the arrow, and attach the long hole 39 of the cleaning roller 25 to the pin 32.
a into place (Fig. 5D). Finally, the front panel 40 is attached and the replacement of the cleaning roller 25 is completed.

According to this embodiment, when the cleaning roller 25 is to be replaced due to dirt, only the cleaning roller 25 can be easily taken out by removing the front panel 40 and moving the knob 36.
Since it is replaceable, it can be replaced very easily and the mechanism is simple.

Note that the cleaning roller 25, which is a replacement member, is also simple and inexpensive. Further, since the cleaning cloth 38 wound around the cleaning roller 25 is wound in a spiral,
No traces such as grooves remain on the optical card 2 even after cleaning. Furthermore, since both end surfaces of the cleaning roller 25 have the same shape, there is no possibility of assembling the left and right parts incorrectly when replacing them. Further, since the width of the cleaning roller 25 is almost the same as the width of the optical card 2, the rear rubber roller 6 cleans not only the recording section 2a of the optical card 2 but also the non-recording section 2b. , it does not get dirty due to dirt, etc., and its lifespan is extended. In addition, since the card guide 28, sensor B 29, shutter 26, and rotating shaft A 27 are attached to the front panel 40, the cleaning roller 25
When replacing the cleaning roller 25, the cleaning roller 25 can be easily replaced by removing the front panel 40. Also,
The rotation direction of the cleaning roller 25 is the front rubber roller 2.
Since the optical card 2 rotates in the opposite direction to the direction of rotation of the optical card 4, the optical card 2 is smoothly drawn in when inserted.

Further, since the separation operation between the rear rubber roller 6 and the lock pin 16 is performed by driving one solenoid 20, the number of parts is small and the cost is low. Also, lock hole 1 of shuttle 1
When the lock pin 16 is fitted into the shuttle l, the sensor A23 is positioned slightly in the Z' force direction from the Z' side end surface of the left collar 4. The sensor A23 can be used to detect whether the sensor A23 is completely contained, and the number of detection members can be reduced. In addition, by opening the shutter 26 only when inserting and ejecting the optical card 2, dirt and dust are prevented from entering from the card guide 28, and when the optical card 2 is inside the device, Even if I try to insert a card, the shutter 26
Since it remains closed, it will not collide with the shuttle 1 and the optical card 2 that are being driven.

In the above embodiment, a recording/reproducing device for an optical card 2 has been described, but it goes without saying that the device is not limited to an optical card, and also includes a magnetic card and other cards. The cleaning roller 25 also has a cleaning cloth 3.
8 was explained, but cleaning paper,
It also includes all other cleaning materials such as chamois and felt.

FIG. 6 is a partially enlarged view of a cleaning section according to a second embodiment of the present invention. The same reference numerals are given to parts corresponding to those in the first embodiment. As in the first embodiment, a cleaning roller 25 is located above the front rubber roller 24. but,
The cleaning roller 25 has a left shaft 25a and a left shaft 251.
].

A locking pin 41 is press-fitted into the left shaft 25b, and a rotation shaft 42 is fitted into the left shaft 25b. A groove 43 is formed at the tip of the rotation shaft 42, and a locking pin 41 is fitted into the groove 43, thereby transmitting the rotational drive of the rotation shaft 42 to the left shaft 25b. left axis 25
The tip of a has a conical shape, and the conical portion is in contact with the pivot ball bearing 44. The pivot ball bearing 44 is the fitting material 4
5, and the fitting member 45 is movable in the cylindrical direction of the holding member 46 in the X direction.

Further, the fitting member 45 is pressed by a coil spring 47 from the side opposite to where the pivot ball bearing 44 is press-fitted.

Further, a stopper 46a is formed at the tip of the holding member 46 to prevent the fitting material 45 from flying out or falling from the holding member 46 when the cleaning roller 25 is removed. Further, a set screw 48 is attached to the holding member 46, and when the set screw 48 is tightened, the fitting member 45 cannot be moved in the X direction.

Next, the operation of this embodiment will be explained. First, to explain the card conveyance operation, a card (not shown) is held between the front rubber roller 24 and the cleaning roller 25, and frictional force is generated between the front rubber roller 24 and the card, causing the front rubber roller 24 to rotate. Card transport is performed by force. Also, together with the front rubber roller 24, the rotation shaft 4
2 also rotates. When the rotation shaft 42 rotates, the left shaft 25b and the cleaning roller 25 rotate due to the engagement between the groove 43 of the rotation shaft 42 and the locking pin 41. The cleaning roller 25 rotates at a relative speed to the card conveyed by the front rubber roller 24. The rotation direction of the cleaning roller 25 may be the same as or different from the rotation direction of the front rubber roller 24. Since the conical portion at the tip of the left shaft 25a of the cleaning roller 25 is in contact with the pivot ball bearing 44, the cleaning roller 25 rotates with low friction. When the card is transported, the cleaning roller 25 receives a force in the Y direction because the card is held between the cleaning roller 25 and the front rubber roller 24. The force is transmitted to the pivot ball bearing at the conical end of the left shaft 25a, pushing the fitting material 45 in the X direction. However, since the fitting member 45 is fixed with a set screw 47, it does not move.

Next, a method for replacing the cleaning roller 24 will be explained according to FIG. 7. First, as in the case of the first embodiment, the front panel (not shown) is removed. The cleaning roller 25 is installed as shown in FIG. 7A. Next, loosen the set screw 48 by turning it counterclockwise (FIG. 7B). Next, the cleaning roller 25 is moved in the X direction as shown in FIG. 7C. Subsequently, as shown in the seventh diagram, the cleaning roller 25 can be removed by moving the left shaft 25b in the R direction and then in the S direction.

To install a new cleaning roller 25, the cleaning roller 25 can be removed in the reverse order. Finally, by attaching a front panel (not shown), replacement of the cleaning roller 25 is completed.

According to this embodiment, when replacing the cleaning roller 25, only the cleaning roller 25 can be easily removed by removing the front panel, loosening the set screw 48, and moving the cleaning roller 25 in the X direction, R direction, and S direction. It is easy to replace, and the mechanism is simple. Furthermore, since the cleaning roller 25, left shaft 25b, and left shaft 25a are integrally constructed and can be replaced, the work is very easy and can be replaced in a short time. Also, the cleaning roller 2
By using the pivot ball bearing 44 for the bearing of the left shaft 25a of No. 5, when the cleaning roller 25 is replaced, the cleaning roller 25 can be moved in the R direction and replaced. Further, since the pivot ball bearing 44 is pressed by the coil spring 47, the positioning of the cleaning roller 25 is automatically performed after the new cleaning roller 25 is installed.

FIG. 8 is a partially enlarged view of a cleaning roller 25 according to a third embodiment of the present invention. The structure of the cleaning section is the sixth
Although it is almost the same as the second embodiment shown in the figure, in contrast to the second embodiment, in which the cleaning roller 25, the left shaft 25a, and the left shaft 25b are integrally constructed, the third embodiment has the construction shown below. It has become. A cleaning shaft 49 passes through the center of the cleaning roller 25 and is separable from the cleaning roller 25. Cleaning shaft 49
A locking pin 41 is press-fitted into the left end, and the right end has a conical shape. Further, a stop pin 50 is press-fitted into the cleaning shaft 49, and a slot 51 is formed in the end surface of the cleaning roller 25 so that the stop pin 50 is engaged. Due to the engagement of the stop pin 50 and the slot 51,
The cleaning shaft 49 and the cleaning roller 25 rotate together. An E ring 52 is attached to the cleaning shaft 49.
is provided to restrict movement of the cleaning roller 25 in the X direction with respect to the cleaning shaft 49.

Next, the operation of this embodiment will be explained. The card conveyance operation and the cleaning roller 2 from the cleaning section
The replacement method of No. 5 is the same as in the second embodiment. In the third embodiment, the cleaning roller 2 removed from the cleaning section
5 can also be removed from the cleaning shaft 49. The replacement method will be explained below. First, E I
Remove J Song 2 from cleaning shaft 49. next,
Remove the cleaning roller 25 from the cleaning shaft 49. Then, insert a new cleaning roller 25 into the cleaning shaft 49 and fasten it with the EU song 2. With this, the replacement of the cleaning roller 25 is completed.

According to this embodiment, similarly to the second embodiment, the cleaning roller 25 can be replaced very easily from the cleaning section. Furthermore, the cleaning roller 25 removed from the cleaning section can be easily pulled out from the cleaning shaft 49 by simply removing the E-ring 52. Further, by making the cleaning roller 25 and the cleaning shaft 49 separable and making only the cleaning roller 25 replaceable, the cost of replacement parts can be reduced.

FIG. 9 is a partially enlarged view of a cleaning section according to a fourth embodiment of the present invention. In this embodiment, a cleaning roller 25 is located above the front rubber roller 24. A left shaft 25b1 and a right shaft 25a are attached to both ends of the cleaning roller 25.
are integrally constructed. A locking pin 41 is attached to the left shaft 25b.
is press-fitted, and the rotating shaft 42 is fitted from the tip side. A groove 43 and a tapered portion 52 are formed at the tip of the rotation shaft 42 . A locking pin 41 fits into the groove 43 and transmits the rotational drive of the rotation shaft 42 to the left shaft 25b. The right shaft 25a is in contact with the bearing 53. The bearing 53 is press-fitted into the cylinder 54. The cylinder 54 is attached to a side plate 56 with fixing screws 55, and a handle 57 is formed on the cylinder 54. A magnet 58 is provided at the inner bottom of the tube 54, and a tube guide 59 is provided near the outer periphery of the cylindrical portion. Next, the operation of this embodiment will be explained. First, the card conveyance operation will be described. A card (not shown) is held between a front rubber roller 24 and a cleaning roller 25, and the card is conveyed by the rotational driving force of the front rubber roller 24. In addition, the rotation shaft 4 together with the front rubber roller 24
2 also rotates. When the rotation shaft 42 rotates, the left shaft 25b and the cleaning roller 25 rotate due to the engagement between the groove 43 of the rotation shaft 42 and the locking pin 41. The cleaning roller 25 rotates at a relative speed to the card conveyed by the front rubber roller 24. The cleaning roller 25 may rotate in the same direction as the front rubber roller 24 or in a different direction. Right shaft 25a of cleaning roller 25
contacts the bearing 53 and rotates with low friction.

Next, a method for replacing the cleaning roller 25 will be explained according to FIG. 10. Since the cleaning roller 25 is installed as shown in FIG. 10A, first,
Remove the fixing screw 55 (Fig. 10B).

Next, grip the handle 57 and move it in the X direction (FIG. 10C).

In this way, the cleaning roller 25 can be removed from the device. Next, the cleaning roller 25 is removed from the cylinder 54. Since the cleaning roller 25 is simply attracted to the magnet 58 attached inside the cylinder 54, it can be easily removed. Next, install a new cleaning roller and assemble it into the apparatus in the order of C-B-A in Figure 1O. When the cleaning roller 25 is assembled into the device, the locking pin 41 is inserted into the groove 43 by the tapered portion 52 of the rotating shaft 42.
be drawn into. In this way, the cleaning roller 2
5 is completed.

According to this embodiment, when replacing the cleaning roller 25, the cleaning roller 25 can be taken out by removing the fixing screw 55 and pulling out the handle 57, so that the cleaning roller 25 can be easily replaced.
The mechanism is also simple. In addition, the cleaning roller 25
Since the left shaft 25b and the right shaft 25a are integrally constructed and can be replaced, the work is very easy and can be replaced in a short time. Further, since it is removed from the side plate 56 side, there are no restrictions on the design of the front panel (not shown).
