Description

  The present invention relates to a drawer mechanism for pulling out a tray for holding a medium from a processing unit that processes a disk-shaped medium such as a CD or a DVD, and a media processing apparatus including the drawer mechanism.

  In recent years, disk dubbing devices that write data to a large number of media such as blank CDs and DVDs, and media processing devices such as CD / DVD publishers that can produce and issue media by performing data writing and label printing are used. It is being As this type of media processing apparatus, a device including a drive that writes data to the media and a transport arm that grips and transports the media to the drive is known (for example, see Patent Document 1).

US Pat. No. 5,734,629

In the media processing apparatus as described above, the drive for writing data to the media includes a media tray that moves forward and backward with respect to the drive body by the rack and pinion, and the media tray is pulled out from the drive body. Then, the transport arm that grips and transports the media moves up and down, and releases or picks up the media with respect to the concave portion of the media tray.
By the way, the media tray that advances and retreats by the rack and pinion may vary depending on the ambient temperature, voltage fluctuation to the drive motor, durability, and the like when it is pulled out.
If the stop position of the drawn media tray varies as described above, the horizontal position of the transport arm with respect to the media tray shifts, and this interferes with the delivery and reception of the media by the transport arm with respect to the media tray receiving recess. However, the data cannot be smoothly written to the medium by the drive.

  The present invention has been made in view of the above circumstances, and a drawer mechanism capable of reliably pulling out a tray holding the medium to a predetermined position from a processing unit that processes the medium, and various processes for the medium by including the pull-out mechanism. It is an object of the present invention to provide a media processing apparatus capable of smoothly performing the above with high reliability.

  In order to achieve the above object, a drawer mechanism according to the present invention includes a tray that can be advanced and retracted having an accommodating portion that holds media, a drawer member that has an engaging portion that can be engaged with the tray, and drives the drawer member. And a moving mechanism that moves the engaging portion to engage with the tray and moves the tray forward in the pull-out direction to a predetermined position.

  According to the drawer mechanism having this configuration, the drawer member having the engaging portion engageable with the tray is driven by the moving mechanism, so that the engaging portion moves while engaging the tray and the tray is moved forward in the drawing direction. Since the tray is moved to a predetermined position, the tray can be pulled out with high accuracy and reliability even if the protruding position of the tray varies due to the ambient temperature, voltage fluctuation to the drive motor, durability, and the like.

  The drawer member includes the engagement portion that can be engaged with an end portion of the tray in the pull-out direction, and swings so that the engagement portion protrudes and disappears in the movement locus of the tray. A drawer lever is preferred.

  According to the pull-out mechanism of this configuration, the engaging portion is swung so as to appear and disappear in the movement trajectory of the tray, so that the engaging portion of the pull-out lever is engaged with the end portion on the front side in the pull-out direction of the tray. Thus, the tray is moved forward in the pulling direction, whereby the tray can be pulled out to a predetermined position in the pulling direction forward with high accuracy and reliability.

  The moving mechanism includes a drive motor, a swing plate to which the drawer lever is attached, and a drive conversion mechanism that moves the swing plate in the front-rear direction while swinging the swing plate by the rotational force of the drive motor. The drive conversion mechanism includes a rotating body rotated by the drive motor, a pin provided at an eccentric position of the rotating body, and a pin formed by a long hole along the vertical direction formed in the swing plate. A sliding hole that is movably inserted, a cam groove that is formed on both or at least one of the front end side and the rear end side of the swing plate, and has an inclined portion that is gradually inclined upward toward the end portion; and It is preferable to include a protrusion formed on the base member that holds the swing plate and inserted into the cam groove.

  According to this configuration, when the rotating body is rotated by the drive motor, the pin provided at the eccentric position of the rotating body is slid within the sliding hole of the swinging plate so that the swinging plate can be easily moved back and forth. It can be moved in the direction. When the swinging plate is moved in the front-rear direction, the swinging plate is swung along the tilting direction by the protrusion passing through the inclined portion of the cam groove. The front end side having the engaging portion of the attached drawer lever can be raised to engage the engaging portion with the tray.

  Further, it is preferable that the pull-out lever is supported in a state where it can move in the front-rear direction with respect to the swing plate and is biased forward by a biasing member.

  According to this configuration, the drawer lever is supported so as to be movable in the front-rear direction with respect to the swinging plate and urged forward by the urging member. Even if the engaging portion of the drawer lever is engaged with the tray, the drawer lever moves relative to the swinging plate against the urging force of the urging member, so that it is impossible for the locked tray. It is possible to avoid the addition of a pulling force and to prevent damage to the media processing unit and the pulling mechanism.

  Further, the pull-out lever is pivoted by contacting a regulating piece formed on the swing plate with a rear end thereof being rotatable with respect to the swing plate and a front end being biased upward by a biasing member. Is preferably supported in a regulated state.

  According to this configuration, the rear end side of the pull-out lever is rotatable with respect to the swing plate, and the front end side is biased upward by the biasing member so as to come into contact with the regulating piece formed on the swing plate. Therefore, even if the engaging part of the drawer lever is engaged with the tray when the tray is locked in the middle, the front end of the drawer lever is used as the biasing force of the biasing member. By depressing and turning against, it is possible to release the engagement state of the engagement portion of the drawer lever with the tray.

  The tray can be advanced and retracted by rotating a pinion meshed with a rack provided along the advancing and retreating direction, and the engaging portion of the drawer lever is located at a position near the rack of the tray. And is preferably engaged with the tray.

  According to this configuration, since the engaging portion of the pull-out lever is engaged with the tray at a position near the rack of the tray, the pull-out force when pulling out the tray by engaging the engaging portion of the pull-out lever is near the rack. Thus, the application of stress due to a bending moment due to the addition of the pulling force to the tray can be suppressed as much as possible, and the tray can be pulled out smoothly.

  Furthermore, the media processing apparatus of the present invention is characterized by including a transport mechanism for delivering media to the tray pulled out from the media processing unit by the pull-out mechanism.

According to the media processing device having this configuration, the tray of the media processing unit can be pulled out to a predetermined position with high accuracy, so that the media is transferred with high accuracy and certainty by the transport mechanism to the tray storage unit. be able to. Thereby, the processing by the media processing unit can be smoothly performed with high reliability.
Also, even if the tray movement accuracy is somewhat low, media can be delivered reliably, so that a media processing unit made of a low-cost general-purpose product can be used, and costs can be reduced.

A spur gear 189 is meshed with the interlocking gear 152. Thus, when the driven compound gear 183 rotates, the rotational force is transmitted to the upper and lower interlocking gears 152, and these interlocking gears 152 rotate in the same direction.

  A switch 191 is provided on the back surface of the base member 142. The switch 191 is provided with an operating rod 192. In this sensor 191, when the driven side composite gear 183 reaches a predetermined rotational position, the operating projection 183a provided at the central portion thereof comes into contact with the operating rod 192, and the operating rod 192 is tilted. The supply of drive current to the drive motor 181 is stopped.

Next, the delivery operation of the medium M to the media tray 41a of the media drive 41 of the transport arm 36 will be described.
When the transfer operation of the medium M in any one of the media drives 41 to which the medium M is to be transferred is started, the drive motor of the tray drive mechanism of the media drive 41 is driven, and the media tray 41a is projected by the rack and pinion. At the same time, the driving of the drawer mechanism 130 is started.

In the pull-out mechanism 130, the drive motor 181 is driven, and the rotational force of the rotating shaft 181a is transmitted to the driven composite gear 183 via the drive composite gear 182 and rotated in the direction indicated by the arrow A in FIGS. The Then, the rotational force of the driven side composite gear 183 is transmitted to the respective interlocking gears 152 of the respective drawing mechanism portions 132A and 132B, and these interlocking gears 152 are rotated in the direction indicated by the arrow B in FIG. When the interlocking gear 152 is rotated, the pin 155 of the interlocking gear 152 arranged at the rear position moves eccentrically while sliding in the sliding hole 162 of the swinging plate 161, so that the swinging plate 161 is moved. Pushed forward.

The swing plate 161 pushed forward is raised at the front end side when the projections 165 and 166 on the base member 142 side inserted through the cam grooves 163 and 164 pass through the inclined portions 163a and 164a of the cam grooves 163 and 164, respectively. And the rear end side is lowered.
As a result, as shown in FIG. 14, the drawer lever 172 attached to the swing plate 161 swings together with the swing plate 161, so that the engaging portion 171 on the front end side is moved in the movement path of the media tray 41a. To the front side of the end plate 41c in the vicinity of the rack 41d formed in the vicinity of one side of the media tray 41a that has already protruded with a slightly small protrusion amount. 171 engages. As a result, the media tray 41a is pulled forward by the pull-out lever 172.

  At this time, if the media tray 41a of the media drive 41 is locked due to unforeseen factors, as shown in FIG. 15, the lever 172 in which the engaging portion 171 is engaged with the end face plate 41c of the media tray 41a is It moves backward (in the direction of arrow C in FIG. 15) relative to the swinging plate 161 along the connecting hole 173 formed of a long hole against the urging force of the tension spring 176. Thereby, it is possible to avoid applying an excessive pulling force to the locked media tray 41a, and it is possible to prevent the media drive 41 and the pulling mechanism 130 from being damaged.

  In addition, when the media tray 41a of the media drive 41 is locked in this way, the user is notified by an error display. In this case, as shown in FIG. 16, the user pushes down the front end of the pull-out lever 172 engaged with the engaging portion 171 to the locked media tray 41a against the urging force of the tension spring 176, The drawer lever 172 is rotated in the direction of arrow D in FIG. In this way, the engagement state of the engaging portion 171 of the pull-out lever 172 with the media tray 41a can be released, and the media tray 41a can be pushed in manually.

  When the interlocking gear 152 rotates 180 degrees and the pin 155 reaches the front position, the forward movement of the swinging plate 161 is stopped, and the drawing of the media tray 41a by the pull-out lever 172 is completed. The tray 41a is disposed at a predetermined position that is a transfer position by the transfer arm 36, and the transfer of the medium M to the accommodation recess 41b by the transfer arm 36 is enabled.

  Thereafter, when the interlocking gear 152 is further rotated, when the pin 155 of the interlocking gear 152 slides in the sliding hole 162 of the swinging plate 161 and moves backward from the front position, the swinging plate 161 moves backward. Be drawn. The swinging plate 161 drawn backward is lowered on the front end side when the protrusions 165 and 166 on the base member 142 side inserted through the cam grooves 163 and 164 pass through the inclined portions 163a and 164a of the cam grooves 163 and 164, respectively. And the rear end side is raised. As a result, the pull-out lever 172 attached to the swing plate 161 swings together with the swing plate 161, so that the engaging portion 171 on the front end side is lowered while being retracted from the movement trajectory of the media tray 41a. The engagement portion 171 is disengaged from the rear surface of the end face plate 41c at the front end of the media tray 41a.

  When the interlocking gear 152 further rotates and the pin 155 reaches the rear position, the operating convex portion 183a of the driven-side compound gear 183 comes into contact with the operating rod 192, the operating rod 192 is turned down and turned off, and the drive motor 181 is turned on. In each of the drawer mechanism portions 132A and 132B of the drawer mechanism 130, the drawer lever 172 is pulled backward and the engaging portion 171 is lowered.

The drawer mechanism 130 performs the same operation in each of the drawer mechanism sections 132A and 132B. That is, in the publisher 1, the media tray 41a is pulled out by either the upper media drive 41 or the lower media drive 41. However, the drawer mechanisms 132A and 132B are connected to the media tray 41 of the upper media drive 41. The operation is performed when the 41a is pulled out and when the media tray 41a of the upper media drive 41 is pulled out.

  As described above, according to the pull-out mechanism according to the above-described embodiment, the pull-out lever 172 having the engaging portion 171 that can be engaged with the end portion of the media tray 41a on the front side in the pull-out direction is rocked. Since the joint portion 171 is raised and engaged with the media tray 41a and moved forward in the pulling direction of the media tray 41a to a predetermined position, the protruding position of the media tray 41a is the ambient temperature, voltage fluctuation to the drive motor, durability Even if it varies due to the above, the media tray 41a can be pulled out with high accuracy and reliability.

  Specifically, by rotating the interlocking gear 152 by the drive motor 181, the pin 155 provided at the eccentric position of the interlocking gear 152 is slid in the sliding hole 162 of the swinging plate 161 to swing. The plate 161 can be easily moved in the front-rear direction. When the swing plate 161 is moved in the front-rear direction, the protrusions 165 and 166 pass through the inclined portions 163a and 164a of the cam grooves 163 and 164, so that the swing plate 161 is moved along the tilt direction. Since it is swung, the front end side having the engaging portion 171 of the pull-out lever 172 attached to this swinging plate 161 can be raised to engage the engaging portion 171 with the media tray 41a. Thereby, the media tray 41a can be pulled out with high accuracy and reliability.

  Further, since the drawer lever 172 is supported so as to be movable in the front-rear direction with respect to the swing plate 161 and biased forward by the tension spring 176, the media tray 41a is locked in the unlikely event. Even if the engaging portion 171 of the pull-out lever 172 is engaged with the media tray 41a, the pull-out lever 172 moves relative to the swinging plate 161 against the urging force of the tension spring 176, thereby moving backward. It is possible to avoid applying an excessive pulling force to the locked media tray 41a, and it is possible to prevent the media drive 41 and the pulling mechanism 130 from being damaged.

  Further, the rear end side of the pull-out lever 172 is rotatable with respect to the swing plate 161 and the front end side is urged upward by the tension spring 176 so as to come into contact with the regulating piece 178 formed on the swing plate 161 to rotate. Therefore, even if the engaging portion 171 of the drawer lever 172 is engaged with the media tray 41a with the media tray 41a locked in the middle, the front end of the drawer lever 172 is By pushing down and rotating against the urging force of the tension spring 176, the engagement state of the engagement portion 171 of the pull-out lever 172 with the media tray 41a can be released.

  Further, since the engaging portion 171 of the drawer lever 172 is engaged with the media tray 41a at a position near the rack 41d of the media tray 41a, the engaging portion 171 of the drawer lever 172 is engaged to pull out the media tray 41a. Can be applied to a position in the vicinity of the rack 41d, thereby suppressing the application of stress due to a bending moment or the like due to the addition of the drawing force to the media tray 41a as much as possible and smoothly drawing out the media tray 41a. .

Then, according to the media processing device including the publisher 1 having the above-described drawer mechanism, the media tray 41a of the media drive 41 can be pulled out to a predetermined position with high accuracy, so that the housing recess 41b of the media tray 41a can be pulled out. It is possible to accurately and reliably deliver the medium M by the transport arm 36. Thereby, the process by the media drive 41a can be smoothly performed with high reliability.
Further, even if the movement accuracy of the media tray 41a is somewhat low, the media M can be reliably delivered, so that the media drive 41 made of a low-cost general-purpose product can be used, and the cost can be suppressed.
