[0041]
Next, with reference to FIGS. 8 to 10, the auxiliary tray 130 and the auxiliary tray driving unit 200 which are the most characteristic portions of the ink jet printer 100 will be described. 8 is a perspective view showing the overall configuration of the auxiliary tray driving means 200, FIG. 9 is an exploded perspective view showing a main part of the auxiliary tray driving means 200, and FIG. 3 is a plan view showing a main part of FIG.
[0042]
The auxiliary tray 130 and the auxiliary tray driving unit 200 are built in the housing 101. Although the details will be described later, the auxiliary tray 130 can reciprocate from a standby position in the casing 101 shown in FIG. 8 to a disc loading / unloading position outside the casing 101 through the paper feed roller 146 and the discharge roller 149. It is arranged in. As described above, since the auxiliary tray 130 is always provided in the ink jet printer 100, it is troublesome to manage the separate auxiliary tray as in the related art when not in use and to insert the auxiliary tray into the printer body when in use. Can be omitted.
[0043]
The auxiliary tray drive unit 200 uses a drive motor 171 of the transport drive unit 170 as a drive source, and synchronizes the movement of the auxiliary tray 130 with the automatic adjustment of the paper gap with the recording head 153 (auto paper gap (APG)). Do it. As described above, by using the driving source of the auxiliary tray driving unit 200 also as the driving motor 171 which is the driving source of the transport driving unit 170, the feeding amount of the auxiliary tray 130 and the feeding amount of the paper feed roller 146 are matched, and the auxiliary tray Damage to the paper feed roller 146 due to interference with 130 can be avoided. Further, since the operation of the auxiliary tray 130 can be detected by the encoder 173 of the transport driving unit 170, there is no need to provide a new detecting unit, and the cost can be reduced.
[0044]
The auxiliary tray driving means 200 includes a driving force switching mechanism 210, a driving force transmission gear mechanism 220, an auxiliary tray lock mechanism 230 shown in FIG. 9, and an APG switching lever mechanism 240 shown in FIG. The driving force of the driving motor 171 of the transport driving unit 170 is transmitted to the paper feed roller 146 via a gear mechanism 172, and the driving force at that time is transmitted via a gear 174 fitted to the paper feed roller 146. The driving force is also transmitted to the driving force switching mechanism 210. When the auxiliary tray 130 moves, the driving force switching mechanism 210 is switched to the driving force transmission gear mechanism 220 side, so that the driving force of the driving motor 171 is transmitted to the auxiliary tray 130 via the driving force transmission gear mechanism 220. Is done. Thus, rotation of the paper feed roller 146 and movement of the auxiliary tray 130 can be realized by one drive motor 171. Hereinafter, among the above-described components 210, 220, 230, and 240 of the auxiliary tray driving means 200, the driving force transmission gear mechanism 220 will be described with reference to FIG. 9, and the APG switching lever mechanism 240 will be described with reference to FIG. The force switching mechanism 210 will be described in detail with reference to FIGS. 11 to 15, and the auxiliary tray lock mechanism 230 will be described in detail with reference to FIGS.
[0045]
The driving force transmission gear mechanism 220 is a mechanism for transmitting the driving force of the driving motor 171 to the auxiliary tray 130. As shown in FIG. 9, a first gear 221 that meshes with the driving force switching mechanism 210, and the first gear 221 The second and third gears 222 and 223 for converting the horizontal rotation axis of the gear 221 into the vertical rotation axis, the fourth gear 224 and the auxiliary tray 130 arranged coaxially with the third gear 223 are provided. A fifth gear 225 that meshes with the formed rack gear 133 is provided. Thus, the driving force of the driving motor 171 of the transport driving unit 170 can be efficiently transmitted to the auxiliary tray 130.
[0046]
The APG switching lever mechanism 240 is a mechanism for automatically adjusting the paper gap with the recording head 153 when the auxiliary tray 130 moves, and includes a first arm 241 and a second arm 242 as shown in FIG. . One end of the first arm 241 is locked to the cam groove 132 of the auxiliary tray 130, one end of the second arm 242 is locked to the other end of the first arm 241, and the middle part is a recording head. 153, and the other end is connected to the sheet discharge roller 148. Then, in synchronization with the movement of the auxiliary tray 130, the recording head 153 and the paper discharge roller 148 are moved from the first arm 241 via the second arm 242.
[0047]
That is, since the thickness of the auxiliary tray 130 is larger than the thickness of the recording paper, the distance between the printing surface of the optical disk and the nozzle surface of the recording head 153 is larger than the distance between the printing surface of the recording paper and the nozzle surface of the recording head 153. The recording head 153 is raised so as to be equal to the proper distance. In addition, the discharge jagged roller 148 is retracted upward so that the printing surface of the optical disc does not come into contact with the discharge jagged roller 148 and is damaged. The driven roller 145 is made of plastic, rubber, or the like. The driven roller 145 does not need to be retracted because it is not damaged when it comes into contact with the printing surface of the optical disc. 130 needs to be inserted and pushed up with a force of, for example, 3.92 N (400 gf) or more. Further, a claw portion is formed between the driven rollers 145 in the paper guide holding the driven roller 145, and the auxiliary tray 130 is devised to avoid contact with the claw portion. Will be described later.
[0048]
Although not shown, a detection unit is provided for detecting that the auxiliary tray 130 is pushed in the direction of the standby position by the user when the auxiliary tray 130 is located at the disk loading / unloading position. By automatically returning the auxiliary tray 130 to the standby position when a detection signal is received from the detection means, it is possible to prevent the auxiliary tray 130 from being forcibly pushed from the disk loading / unloading position toward the standby position. Therefore, the paper feed roller 146, the paper discharge roller 149, and the recording head 153 do not collide with the auxiliary tray 130 and are not damaged or deformed. The detecting means includes, for example, a plurality of radially formed slits, and a rotating disk that rotates in conjunction with the movement of the auxiliary tray 130, and is disposed on both sides of the rotating disk, and detects the amount of light that changes due to the rotation of the rotating disk. It has a photo interrupter for detection.

11 (A) and 11 (B) are a perspective view and a side view showing the driving force switching mechanism 210, FIG. 12 is an exploded perspective view thereof, and FIG. 13 is an exploded perspective view of the same viewed from the opposite side. . This driving force switching mechanism 210 is a mechanism for switching the transmission of the driving force of the driving motor 171 to the driving force transmission gear mechanism 220 side, and as shown in FIGS. The configuration is such that the 211, the second transmission gear 212, and the lever 213 are fitted to the rotating shaft 216 together with the compression spring 214 and the stopper 215. That is, the first transmission gear 211, the compression spring 214, the second transmission gear 212, the lever 213, and the stopper 215 are fitted in the rotation shaft 216 in this order.
[0050]
The first transmission gear 211, as shown in FIGS. 12 and 13, has a gear portion 211a that always meshes with a gear 174 fitted to the paper feed roller 146, and protrudes axially from one end surface of the gear portion 211a. And a cylindrical shaft portion 211b into which the rotating shaft 216 is fitted. Similarly, the shaft portion is integrally formed so as to protrude in the axial direction from the end face of the gear portion 211a and at equal intervals around the shaft portion 211b. It has three bar-shaped locking portions 211c. Between the locking portions 211c on the outer peripheral surface of the shaft portion 211b, three restricting portions 211d extending in the axial direction that allow the second transmission gear 212 to slide freely while restricting the rotation of the second transmission gear 212 are integrally formed. . The locking portion 211c has a tip formed in a wedge-shaped hook shape, and is bent in a radial direction like a cantilever.
[0051]
As shown in FIGS. 12 and 13, the second transmission gear 212 includes a gear portion 212a that can mesh with the first gear 221 of the driving force transmission gear mechanism 220, and an axial direction from one end surface of the gear portion 212a. The first transmission gear 211 has a cylindrical shaft portion 212b that is integrally formed so as to protrude and into which the shaft portion 211b of the first transmission gear 211 is fitted. Six slit portions 212c into which the three locking portions 211c and the three regulating portions 211d of the first transmission gear 211 can be inserted are formed in the shaft portion 212b.
[0052]
As shown in FIGS. 12 and 13, the lever 213 protrudes outward from an outer edge of the rotating portion 213 b having a hole 213 a formed around the engaging portion 211 c of the first transmission gear 211 and an outer edge of the rotating portion 213 b. And a pressing portion 213d integrally formed so as to protrude outward from the outer edge of the rotating portion 213b substantially opposite to the stopping portion 213c. The stop portion 213c acts to contact the carriage 151 and stop the rotation of the lever 213. The pressing portion 213d abuts on the carriage 151 and is pressed to act to slide the second transmission gear 212 together with the lever 213.
[0053]
The procedure for assembling the driving force switching mechanism 210 in the above configuration will be described. First, one end of the compression spring 214 is pressed against the wedge-shaped hook-shaped tip of the locking portion 211c of the first transmission gear 211, and each locking portion 211c is bent inward, so that the compression spring 214 is moved. It fits around each locking part 211c. At this time, since each locking portion 211c bent inward is restored to the original state by the elastic force, the other end of the compression spring 214 is connected to the wedge-shaped hook-shaped tip of the locking portion 211c. Locked, the compression spring 214 does not come off the first transmission gear 211.
[0054]
Similarly, the other end surface of the gear portion 212a of the second transmission gear 212 is pressed against the wedge-shaped hook-shaped tip of the engagement portion 211c of the first transmission gear 211, and each engagement portion 211c is moved inward. To bend. Then, the respective restricting portions 211d and the respective locking portions 211c of the first transmission gear 211 are inserted into the respective slit portions 212c of the second transmission gear 212, and the shaft portion 212b of the second transmission gear 212 is inserted into the respective locking portions. Fit around 211c. At this time, each of the locking portions 211c bent inward is restored to the original state by the elastic force, so one end surface of the gear portion 212a is attached to the tip of the locking portion 211c formed in a wedge-shaped hook shape. Locked, the second transmission gear 212 also does not come off the first transmission gear 211. The second transmission gear 212 is rotatable together with the first transmission gear 211 by each of the restriction portions 211d inserted into each of the slit portions 212c, and is slidably held along the shaft portion 211b. .
[0055]
Further, similarly, the rotating portion 213b of the lever 213 is pressed against the wedge-shaped hook-shaped tip of the locking portion 211c of the first transmission gear 211, and each locking portion 211c is bent inward to rotate. The part 213b is fitted around each locking part 211c. At this time, the locking portions 211c bent inward are restored to the original state by the elastic force, so that the rotating portion 213b is locked to the wedge-shaped hook-shaped tip of the locking portion 211c. , The lever 213 also does not come off the first transmission gear 211. Since the lever 213 is biased by the compression spring 214 between the first transmission gear 211 and the second transmission gear 212 that are physically constrained in the radial direction and are synchronized, the lever 213 is held. Sliding can be prevented without using a conventionally required wheel stopper or the like, more reliable operation can be obtained, and the load can be reduced.
[0056]
Finally, the rotation shaft 216 is inserted into the shaft portion 211b of the first transmission gear 211, and the retaining member 215 is fitted into the shaft portion 212b of the second transmission gear 212, finally, as shown in FIG. The driving force switching mechanism 210 is completed. The operation of the driving force switching mechanism 210 having such a configuration will be described with reference to FIGS. 11, 14, and 15. FIG.
[0057]
FIG. 14 is a plan view showing the relationship between the driving force switching mechanism 210 and the carriage 151, and FIG. 15 is a perspective view showing the state of the driving force switching mechanism 210 at that time. As shown in FIG. 14A, when the carriage 151 is separated from the home position, the direction in which the second transmission gear 212 is separated from the first gear 221 of the driving force transmission gear mechanism 220 by the compression spring 214. Has been energized. Further, as shown in FIG. 11A, the pressing portion 213d of the lever 213 is rotationally positioned at a position not in contact with the carriage 151. Therefore, the driving force of the driving motor 171 of the transport driving unit 170 is not transmitted to the auxiliary tray 130.
[0058]
When the auxiliary tray 130 is used, first, the driving motor 171 of the transport driving unit 170 rotates once reversely, so that the pressing portion 213d of the lever 213 contacts the carriage 151 as shown in FIG. It is rotated and positioned at the contact position. Then, when the carriage 151 returns to the home position, the carriage 151 comes into contact with and presses the pressing portion 213d of the lever 213, and slides the lever 213 together with the second transmission gear 212 in the moving direction of the carriage 151.
[0059]
Finally, as shown in FIGS. 14B and 15B, the carriage 151 meshes the second transmission gear 212 with the first gear 221 of the driving force transmission gear mechanism 220. Therefore, the driving force of the driving motor 171 of the transport driving unit 170 is transmitted to the auxiliary tray 130. The phase shift between the second transmission gear 212 and the first gear 221 of the driving force transmission gear mechanism 220 is absorbed by the bending of the pressing portion 213d of the lever 213. As described above, since the lever 213 can be slid in parallel with the moving direction of the carriage 151, it is possible to prevent a problem such as a one-sided contact between the lever 213 and the locking portion 211c, and to reduce the driving force to the auxiliary tray 130. The transmission can be switched reliably.
[0060]
16 is a perspective view of the auxiliary tray lock mechanism 230 as viewed from the front side, FIG. 17 is a perspective view of the auxiliary tray lock mechanism 230 as viewed from the rear side, and FIG. 18 is an exploded perspective view thereof. The auxiliary tray lock mechanism 230 is a mechanism for mechanically locking the auxiliary tray 130 at the standby position, and includes a lock lever 231, a lever detector 232, a holder 233, and the like as shown in FIGS. . The auxiliary tray lock mechanism 230 is disposed between the driving force switching mechanism 210 and the auxiliary tray 130, as shown in FIGS. 16 and 17, and operates in conjunction with the driving force switching mechanism 210. I have. By providing such an auxiliary tray lock mechanism 230, it is possible to distinguish between automatic feeding of recording paper and movement of the auxiliary tray 130.
[0061]
As shown in FIG. 18, the lock lever 231 has a substantially F-shaped upper end that is detected by the lever detector 232, a detected part 231 a, a middle end that locks the auxiliary tray 130, and a lower end that is driven. A swing shaft 231d serving as a swing center is protrudingly formed at a substantially central portion so as to function as a pressing portion 231c pressed by the retaining 215 of the force switching mechanism 210. The lever detector 232 is a photo-interrupter having light emitting / receiving sections 232a and 232b, and detects the locked state of the auxiliary tray 130 when the detected section 231a of the lock lever 231 enters and exits between the light emitting / receiving sections 232a and 232b. It has become. The holder 233 has a lever support portion 233a that supports the lock lever 231 so as to swing freely, and a detector holding portion 233b that holds the lever detector 232.
[0062]
The procedure for assembling the auxiliary tray lock mechanism 230 in the above configuration will be described. First, the torsion coil spring 234 is fitted into the swing shaft 231d of the lock lever 231. The swing shaft 231d is fitted into the lever support portion 233a of the holder 233. Then, one end of the torsion coil spring 234 is locked to the lever support portion 233a, and the other end is locked to the lock lever 231. As a result, the lock lever 231 is swingably supported about the swing shaft 231d.
[0063]
Next, by fixing the lever detector 232 to the detector holding portion 233b of the holder 233 and disposing it between the driving force switching mechanism 210 and the auxiliary tray 130, finally, as shown in FIGS. The auxiliary tray lock mechanism 230 is completed. Accordingly, the detected portion 231a of the lock lever 231 can swing between the light emitting / receiving portions 232a and 232b of the lever detector 232 by swinging. The operation of the auxiliary tray lock mechanism 230 having such a configuration will be described with reference to FIGS. Note that FIG. 19B is a diagram illustrating a state where part of FIG. 19A is removed.
[0064]
When the auxiliary tray 130 is at the standby position, the lock lever 231 is urged by the torsion coil spring 234 as shown in FIG. For this reason, as shown in FIG. 19B, the detected part 231a is separated from between the light emitting and receiving parts 232a and 232b of the lever detector 232, and the lock part 231b is inside the lock hole 134 formed in the auxiliary tray 130. I'm stuck in. Therefore, the auxiliary tray 130 is locked at the standby position, and the locked state of the auxiliary tray 130 can be detected by detecting an ON signal from the lever detector 232.
[0065]
In order to use the auxiliary tray 130, when the carriage 151 returns to the home position, the carriage 151 comes into contact with the pressing portion 213d of the lever 213 of the driving force switching mechanism 210 and presses the lever 213 together with the second transmission gear 212. When the slide 151 is slid parallel to the moving direction of the carriage 151, the stopper 215 also slides parallel to the moving direction of the carriage 151 at the same time. At this time, since the pressing portion 231c comes into contact with the retaining member 215 and is pressed, the lock lever 231 rotates clockwise in the drawing.
[0066]
For this reason, as shown in FIG. 20A, the detected part 231a enters between the light emitting and receiving parts 232a and 232b of the lever detector 232, and the lock part 231b is separated from the lock hole 134 formed in the auxiliary tray 130. I do. Therefore, the lock of the auxiliary tray 130 is released in synchronization with the switching operation of the driving force switching mechanism 210, and the fact that the auxiliary tray 130 is in the unlocked state is detected by detecting the OFF signal from the lever detector 232. be able to.
[0067]
Thereafter, when the carriage 151 separates from the home position, the lever 213 returns to the original position together with the second transmission gear 212, and at the same time, the stopper 215 also returns to the original position, so that the lock lever 231 is urged by the torsion coil spring 234. To rotate counterclockwise and return to the original position. However, since the auxiliary tray 130 has started moving, the lock portion 231b comes into contact with the flat back surface of the auxiliary tray 130, and the rotation of the lock lever 231 stops. It stays between the light receiving and emitting units 232a and 232b. Therefore, when the auxiliary tray 130 is separated from the standby position, the OFF signal from the lever detector 232 can be always detected regardless of the state of the lever 213, so that the auxiliary tray 130 is in the unlocked state. Can be detected. Next, the auxiliary tray 130 will be described in detail with reference to FIG.
[0068]
FIG. 21 is a perspective view showing the auxiliary tray 130. The auxiliary tray 130 is formed in a rectangular plate shape of plastic, and has a circular disc recess 131 on which a single optical disc can be placed and stored, and a rear left side face in the drawing. A cam groove 132 for locking the first arm 241 of the APG switching lever mechanism 240 is formed on the side, and a rack gear 133 that meshes with the fifth gear 225 of the driving force transmission gear mechanism 220 is formed on the left side in the figure. ing.
[0069]
According to the auxiliary tray 130 having such a configuration, the optical disk can be accommodated in the disk concave portion 131, so that the displacement of the optical disk during recording can be prevented. Further, since the APG can be mechanically controlled by the cam groove 132 and the movement can be mechanically controlled by the rack gear 133, highly accurate recording can be maintained. Characteristic portions of the auxiliary tray 130 include a groove 135 and an APG regulating lever 137, which will be described below.
[0070]
As shown in FIG. 21, the groove 135 which is a characteristic part of the auxiliary tray 130 has a depth substantially equal to that of the disc recess 131 from the inner wall 131 a of the disc recess 131 on the tip side of the tray to the front of the tray tip. Four are formed at predetermined intervals. As shown in FIG. 22, these grooves 135 are formed so as to correspond to the positions of the claw portions 145a formed between the driven rollers 145 in the paper guide holding the driven rollers 145.
[0071]
Thus, when the auxiliary tray 130 returns from the disk loading / unloading position to the standby position, the driven roller 145 first rises up the inner wall 131a and passes over the hill 136 between the grooves 135, so that the following claw 145a is slightly lifted. In this state, it passes above the groove 135. As described above, by providing the groove 135 on which the claw portion 145a escapes in the auxiliary tray 130, it is possible to prevent the inner wall 131a from coming into contact with the claw portion 145a without retreating the driven roller 145 upward.
[0072]
As shown in FIG. 21, an APG regulating lever 137, which is a characteristic part of the auxiliary tray 130, is provided so as to straddle the rear end of the cam groove 132 and to extend along the rear end of the tray. As shown in FIG. 23, the APG regulating lever 137 has a pivot shaft 137b attached to one end of the guide rod 137a so that the pair of guide rods 137a can maintain a state in which a certain gap is opened. The pivot shaft 137c formed on the left side of the cam groove 132 at the rear end of the tray is pivoted so as to be able to pivot from the position sandwiching the rear end of the tray including the cam groove 132 to a position on the extension of the cam groove 132. 137b is inserted.
[0073]
Here, in order to secure the APG position, one end of the first arm 241 needs to be locked in the cam groove 132 while the auxiliary tray 130 moves from the standby position to the disk loading / unloading position. Requires that the length of the cam groove 132, that is, the length of the auxiliary tray 130 be extremely long. However, if the length of the auxiliary tray 130 is made very long, the depth of the housing 101 of the ink jet printer 100 becomes longer and the size becomes larger.
[0074]
Therefore, as shown in FIG. 24, until one end of the first arm 241 reaches the rear end from the front end (standby position of the auxiliary tray 130) of the cam groove 132, the APG regulating lever 137 moves to the rear of the tray including the cam groove 132. Stand by at the position sandwiching the end. Then, as shown in FIG. 25, after one end of the first arm 241 reaches the rear end of the cam groove 132, the APG regulating lever 137 is kept until the APG regulating lever 137 is located on the extension of the cam groove 132. Locks one end of the first arm 241 instead of the cam groove 132 while being swung by being pushed by one end of the first arm 241. Thus, the APG position can be secured while the auxiliary tray 130 moves from the standby position to the disk loading / unloading position without making the length of the auxiliary tray 130 very long. Therefore, it is not necessary to make the length of the auxiliary tray 130 longer than necessary, and the size of the ink jet printer 100 can be reduced.
[0075]
First, the operation of the ink jet printer 100 having the above-described configuration when recording on a recording sheet will be described. It is assumed that the connection wiring and the connection of the power plug between the ink jet printer 100 and the television system or the computer have already been completed. First, the user presses the take-out button 103 with a finger in the state shown in FIG. 1, and then pulls the finger on a concave portion provided on the bottom surface of the tray 120 to pull the tray 120 forward as shown in FIG. 2. Withdraw to
[0076]
Subsequently, after a plurality of recording sheets are stored in a stacked state at a predetermined position in the main body 111 of the tray 120, the tray 120 is pushed backward and set. At this time, the front of the recording paper is lifted obliquely upward by the hopper 112, and the front end of the uppermost recording paper contacts the paper feed roller 142. Next, the user pulls the stacker 110 forward as shown in FIG. 3 by hanging a finger on the top of the stacker 110 and pulling it. Then, the inkjet printer 100 is set to a standby state, and a recording command is input from a television system, a computer, or the like.
[0077]
Then, as shown in FIG. 7, the uppermost sheet of recording paper P in the tray 120 is guided by the first paper guide 141 and the second paper guide 144 while being rotated in the sub-scanning direction by the rotation of the paper feed roller 142. , And is sandwiched between the sheet feeding roller 142 and the pad 143a, and further sent forward. At this time, if the recording paper P is not only the uppermost one in the tray 120 but a plurality of papers, the uppermost recording paper P and the recording paper P below it are separated by the pad 143a, and the uppermost recording paper P is separated. Only the recording paper P is sandwiched between the paper feed roller 142 and the pad 143a and sent out further forward, and the lower recording paper P is returned into the tray 120.
[0078]
Then, the uppermost recording sheet P is sandwiched between the driven roller 145 and the sheet feed roller 146 and is sent further forward. When the recording paper P reaches the third paper guide 147, the movement of the carriage 151 in the main scanning direction is started. That is, the carriage 151 located at the home position reciprocates between both ends of the recording sheet P conveyed after leaving the home position. Then, the recording head 153 changes the pressure in the pressure generating chamber by, for example, a piezoelectric element with respect to the recording paper P being conveyed in the sub-scanning direction, and discharges the ink stored in the pressure generating chamber from the nozzle, The predetermined recording information is recorded on the recording paper P.
[0079]
At this time, the scanning timing and the ink ejection timing of the recording head 153 are controlled by a dedicated controller board or the like of the control unit 160, and high-precision ink dot control, halftone processing, and the like are executed. Then, the recording paper P is sandwiched between the paper discharge roller 148 and the paper discharge roller 149 and is sent further forward, and the recording paper P on which recording is finally completed is discharged onto the stacker 110.
[0080]
Next, an operation example when printing on the surface of an optical disk using the auxiliary tray 130 and the auxiliary tray driving means 200 will be described with reference to the flowcharts of FIGS. In the standby state, the auxiliary tray 130 is located at the standby position. When the user presses the tray eject button, the driving motor 171 of the transport driving unit 170 rotates in the reverse direction, and the pressing unit 213d of the lever 213 of the driving force switching mechanism 210 is rotationally positioned at a position where the pressing unit 213d contacts the carriage 151 (step S1).
[0081]
Subsequently, when the carriage 151 returns to the home position, the carriage 151 comes into contact with and presses the pressing portion 213d of the lever 213, and slides the lever 213 together with the second transmission gear 212 in the moving direction of the carriage 151 (step S2). . Then, while the carriage 151 is pressing the pressing portion 213d of the lever 213, the driving motor 171 rotates in the reverse direction to slightly rotate the second transmission gear 212, so that the second transmission gear 212 is driven by the driving force transmission gear. The first gear 221 of the mechanism 220 meshes with the first gear 221 (step S3).
[0082]
After the second transmission gear 212 meshes with the first gear 221, the carriage 151 further presses the pressing portion 213 d of the lever 213 to completely mesh the second transmission gear 212 with the first gear 221. (Step S4). Then, a signal from the lever detector 232 of the auxiliary tray lock mechanism 230 is detected, and it is confirmed whether or not the auxiliary tray 130 is in an unlocked state (step S5). If the auxiliary tray 130 is not in the unlocked state, the process returns to step S2 to repeat the above-described operation. In this retry operation, an error display or the like may be displayed when the number of retries is limited, for example, three retries.
[0083]
On the other hand, when the auxiliary tray 130 is in the unlocked state in step S5, the auxiliary tray 130 is moved at a low speed, for example, 0.83 ips until the drive motor 171 rotates forward and the auxiliary tray 130 pushes up the driven roller 145 ( Step S6). Then, when the auxiliary tray 130 reaches the paper discharge roller 149, the auxiliary tray 130 is moved to the disk loading / unloading position at a relatively high speed, for example, 3 ips (step S7). Note that the recording head 153 and the discharge roller 148 move from the first arm 241 of the APG switching lever mechanism 240 via the second arm 242 in synchronization with the movement of the auxiliary tray 130.
[0084]
Thereafter, when the user sets the optical disk on the auxiliary tray 130 and presses the tray set button, the drive motor 171 of the transport driving unit 170 rotates in the reverse direction, and the pressing unit 213 d of the lever 213 of the driving force switching mechanism 210 comes into contact with the carriage 151. The rotational position is determined (step S11). Subsequently, when the carriage 151 returns to the home position, the carriage 151 comes into contact with and presses the pressing portion 213d of the lever 213, and slides the lever 213 together with the second transmission gear 212 in the moving direction of the carriage 151 (step S12). .
[0085]
Then, while the carriage 151 is pressing the pressing portion 213d of the lever 213, the driving motor 171 rotates in the reverse direction to slightly rotate the second transmission gear 212, so that the second transmission gear 212 is driven by the driving force transmission gear. The first gear 221 of the mechanism 220 is engaged with the first gear 221 (step S13). After the second transmission gear 212 meshes with the first gear 221, the carriage 151 further presses the pressing portion 213 d of the lever 213 to completely mesh the second transmission gear 212 with the first gear 221. (Step S14).
[0086]
Then, the drive motor 171 rotates in the reverse direction to move the auxiliary tray 130 at a relatively high speed, for example, 3 ips, before the auxiliary tray 130 comes off the paper feed roller 146 (step S15). Then, when the auxiliary tray 130 reaches a position short of being disengaged from the paper feed roller 146, the auxiliary tray 130 is moved to the standby position at a low speed, for example, 0.83 ips (step S16).
[0087]
Then, a signal from the lever detector 232 of the auxiliary tray lock mechanism 230 is detected, and it is confirmed whether or not the auxiliary tray 130 is locked (step S17). When the auxiliary tray 130 is in the locked state, the processing ends. On the other hand, in step S17, when the auxiliary tray 130 is not in the locked state, when the carriage 151 returns to the home position, the carriage 151 comes into contact with and presses the pressing portion 213d of the lever 213, and pushes the lever 213 to the second transmission gear 212. At the same time, the carriage 151 is slid parallel to the moving direction of the carriage 151 (step S18).
[0088]
Then, while the carriage 151 is pressing the pressing portion 213d of the lever 213, the driving motor 171 rotates in the reverse direction to slightly rotate the second transmission gear 212, so that the second transmission gear 212 is driven by the driving force transmission gear. The first gear 221 of the mechanism 220 is engaged with the first gear 221 (step S19). After the second transmission gear 212 meshes with the first gear 221, the carriage 151 further presses the pressing portion 213 d of the lever 213 to completely mesh the second transmission gear 212 with the first gear 221. (Step S20).
[0089]
Thereafter, a signal from the lever detector 232 of the auxiliary tray lock mechanism 230 is detected, and it is confirmed whether or not the auxiliary tray 130 is in a locked state (Step S21). If the auxiliary tray 130 is not in the locked state, the process returns to step S18 and the above-described operation is repeated. In this retry operation, an error display or the like may be displayed when the number of retries is limited, for example, three retries. On the other hand, when the auxiliary tray 130 is in the unlocked state in step S21, all the processing ends.

Thereafter, the auxiliary tray 130 moves from the standby position to the printing start position, and printing of the optical disk is started. When the printing of the optical disk is completed and the auxiliary tray 130 moves to the disk loading / unloading position, the user removes the optical disk from the auxiliary tray 130 and presses the tray set button. As a result, the auxiliary tray 130 moves from the disc loading / unloading position to the standby position, and the recording head 153 and the discharge jagged roller 148 move to the original positions. Thereafter, the drive motor 171 stops and enters the standby state. By using the auxiliary tray driving means 200 having such a driving force switching mechanism 210, the auxiliary tray 130 can be moved with high accuracy, and thus the printing on the surface of the optical disk can be performed with high accuracy.
