Lock-in detection mechanism is below described, this lock-in detection mechanism is used for detecting that drawer unit 76 is in the lock state or in latch-release state.Figure 17 is the oblique view of lock-in detection mechanism.As shown in figure 17, lock-in detection mechanism has plug-in unit 192 and lock-in detection sensor 191 for lock-in detection, and lock-in detection is located in lock shaft 703 with plug-in unit 192, is the disc-shape of part shortcoming, and lock-in detection sensor 191 uses transmission-type optical sensor.When lock-in detection is inserted between the light accepting part 191b of lock-in detection sensors 191 and illuminating part 191a with plug-in unit 192 after, the light of illuminating part 191a transmitting is subject to lock-in detection and with plug-in unit 192, blocks and cannot be irradiated to light accepting part 191b.Thereby light accepting part 191b can not detect the light of illuminating part 191a transmitting, the signal indication of its output " OFF: shading status ".On the contrary, when not having lock-in detection with plug-in unit 192 between illuminating part 191a and light accepting part 191b, the light of illuminating part 191a transmitting can be irradiated to light accepting part 191b (being the irradiation that light accepting part 191b is subject to the light of illuminating part 191a transmitting), the signal indication " ON: transmissive state " of light accepting part 191b output.Lock-in detection sensor 191 in this example is also referred to as optical sensor, lock-in detection with plug-in unit 192 also referred to as detection parts.
Figure 18 is a routine key structure functional block diagram of the control system of present embodiment.As shown in figure 18, control part 120 is as control device, connecting drawer handle detecting sensor 200, a plurality of recording chart detecting sensor 300, CD-ROM drive motor 701, lock-in detection sensor 191, sets detecting sensor 172 etc.The CPU carrying on control part 120 carries out the program in the ROM that is kept at control part 120, carries out the driving of CD-ROM drive motor 701 and controls, and then carry out every controls such as locking of drawer unit 76.
Drawer handle detecting sensor 200 is positioned on protecgulum 6, is the optical sensor with illuminating part and light accepting part.When user's hand reaches while making not shown plate be subject to pressing in drawer, light accepting part is subject to the irradiation of illuminating part transmitting in this example.Light accepting part is being subject under light-struck state of illuminating part transmitting, and output represents the signal of " ON: transmissive state ", contrary; Light accepting part is not subject under light-struck state of illuminating part transmitting, and output represents the signal of " OFF: shading status ".Yet the present invention is not subject to this structural limitations, for example, can also be configured to, when user's hand reaches and makes not shown plate be subject to pressing in drawer, light accepting part is not subject to the irradiation of illuminating part transmitting, and plate is not while being subject to pressing, and light accepting part is subject to the irradiation of illuminating part transmitting.Whether control part 120, according to the signal of drawer handle detecting sensor 200 (light accepting part) output, detects plate and is pressed.
Control part 120, according to the signal of recording paper sensor 300 outputs in image processing system 1 each portion, judges whether image processing system 1 paperboard occurs, and finds out paperboard happening part.
In addition, control part 120 is also according to the signal of setting detecting sensor 172 outputs, detects the whether state in being set to device main frame portion 5 of drawer unit 76.Therefore, control part 120 plays the effect of the first test section in this example.Moreover control part 120, according to the signal of locking sensor 191 outputs, detects the turned position of Lock Part 160.Therefore, control part 120 also plays the effect of the second test section in this example.And then control part 120 also provides independent power supply control to various loads such as the sensor carrying on drawer unit 76 or motors.Therefore, the control part in this example 120 also plays the effect of power control part.
The below lock-out state during drawer unit 76 of explanation in can not pull unit main frame portion 5 and the latch-release state can pull out drawer unit 76 from device main frame portion 5 time.
As shown in Figure 19 (A), under latch-release state, the live-rollers 162 of Lock Part 160 is positioned at breach 181a and the position corresponding to 181b of locking reception part 180, now, the lock-in detection of lock-in detection mechanism is positioned at the light accepting part 191b of the detecting sensor 191 that just goes out of lock and the other side's of illuminating part 191a position with plug-in unit 192.In this case, the light accepting part 191b of lock-in detection sensor 191 detects the light of illuminating part 191a transmitting, and output represents " ON; Transmissive state " signal.
In the following description, the turned position of the Lock Part in latch-release state 160 is called to " primary importance ".When the turned position of Lock Part 160 is during in primary importance, Lock Part 160 is in both inserting the state of through hole 184 for the locking that also can leave in locking reception part 180.But, the present invention is not subject to the restriction of above-described embodiment, for example, under latch-release state while being positioned at primary importance (be the turned position of Lock Part 1), lock-in detection enters with plug-in unit 192 between the light accepting part 191b and illuminating part 191a of lock-in detection sensor 191, and light accepting part 191b output represents the signal of " OFF: shading status ".
From then on state sets out, and when drawer unit 76 is set in device main frame portion 5 after (closing drawers), Lock Part 160 just inserts the through hole 184 for locking of locking reception part 180.Then, when locking roller 162 moves to the rear that is positioned at drawer unit one square end portion in guide surface 183a and 183b, set to detect with plug-in unit 171 and insert between the light accepting part 172b and illuminating part 172a that sets detecting sensor 172, block the light of illuminating part 172a transmitting.According to the signal of setting detecting sensor 172 outputs, control part 120 detects drawer unit 76 and has been set, and controls CD-ROM drive motor 701 and starts to drive lock shaft 703 to rotate.
After lock shaft 703 rotates, as shown in Figure 19 (B), the live-rollers 162 of Lock Part 160 touches guide surface 183a and 183b, and under the guiding of guide surface 183a and 183b, rearward locking receives face 182a and 182b to move.Like this, live-rollers 162 enters rear under the guiding of guide surface 183a and 183b.As shown in previous Fig. 6, fixing E type ring 722 on the groove of lock shaft 703, for contacting the leading flank of drawer unit back side panel 151.For this reason, when lock shaft 703 will rearward move, drawer unit back side panel 151 is pushed away toward rear by E type ring 722, thereby drawer unit 76 is set in device main frame portion 5.
Live-rollers 162 can rotate on roll shaft 161, while thereby this live-rollers 162 rotate on guide surface and move.Can reduce like this friction impedance between live-rollers 162 and guide surface 183a and 183b, allow Lock Part 160 successfully drawer unit 76 be drawn toward rear.
In the present embodiment, while starting to draw drawer unit 76 from Lock Part 160, pilot pin 152 embeds pilot hole 502, carries out location.If be configured in traction and start (set detecting sensor 172 input signals and be converted to " OFF: shading status " from " ON: transmissive state ") Embedded Division 152b insertion pilot hole 502 of pilot pin 152 before, when manually promoting drawer unit 76, Embedded Division 152b embeds pilot hole 502, and its result is by the promotion friction increasing during manual operation.Especially in the present embodiment as shown in figure 10, two positions, place of drawing at drawer unit back side panel 1 and two positions, place of drawer unit front side board 150, amount to the pilot pin at position everywhere and almost embed pilot hole 502 simultaneously, like this, in during manually pushing, promoting friction force significantly strengthens suddenly, its result user can misread think drawer unit 160 is pushed into traction starting position, thereby stop promoting drawer unit.
On the other hand, in the present embodiment, as shown in figure 20, when the tapered portion 152a3 of pilot pin 152 arrives pilot hole 502, set to detect the clamor signal of 172 outputs of sensing and change " OFF: shading status " into from " ON: transmissive state ", control part 120 detects drawer unit 76 and is set in device main frame portion 5, starts traction (being that CD-ROM drive motor 701 starts to drive).In Lock Part 160 traction drawer units 76, the tapered portion 152a3 of pilot pin 152 moves to pilot hole 502, and Embedded Division 152b embeds pilot hole 502.The traction starting position (when the signal of setting detecting sensor 172 outputs changes " OFF: shading status " into from " ON: transmissive state ") that so just can be subject to Lock Part 160 traction at drawer unit 76 before, suppress to promote the sharply increase of resistance, guarantee can arrive with the drawer unit 76 manually promoting the traction starting position of Lock Part 160.
Pilot pin 152 embeds after pilot hole 502, still rearward traction under the guiding of guide surface 183a and 183b of drawer unit 76, and as shown in figure 20, the 152c of seat surface portion of the pilot pin 152 on drawer unit back side panel 151 etc. encounters main frame back side panel 501.Then, as shown in Figure 19 C, after the live-rollers 162 of Lock Part 160 arrives locking receiving face 182a and 182b, lock-in detection is inserted between the light accepting part 191b and illuminating part 191c of lock-in detection sensors 191 with plug-in unit 192, makes the output signal of lock-in detection sensor 191a become the signal of expression " OFF: shading status ".Control part 120 is received the signal of expression " OFF: shading status " from lock-in detection sensor 191, the state (be in the lock state) of drawer unit 76 in not pulling out from device main frame portion 5 detected, controls CD-ROM drive motor 701 and stops driving.
In the following description, the turned position of the Lock Part being in the lock state 160 is called to the second place.When the turned position of Lock Part 160 is during in the second place, Lock Part 160 can not insert and can not leave the through hole 184 for locking forming in locking reception part 180.But the present invention is not limited.For example can also be configured to, under lock-out state (turned position of Lock Part 160 is when the second place), lock-in detection gets togather the other side position of the light accepting part 191b and the illuminating part 191a that are positioned at the detecting sensor 191 that goes out of lock with plug-in unit 192, light accepting part 191b detects the light of illuminating part 191a transmitting, and output represents the signal of " ON: transmissive state ".
As narrated below, under lock-out state, when control part 120 detects user hand is stretched into drawer unit 76 and wants to pull out drawer unit 76, control CD-ROM drive motor 701 and drive Lock Parts 160 to rotate according to the counter clockwise direction in figure.Live-rollers 162 moves to guide surface 186a and 186b from locking receiving face 182a and 182b like this.Then as shown in Figure 19 D, the live-rollers 162 contacting with locking receiving face 182a arrives breach 181a position, the live-rollers 162 contacting with locking receiving face 182b arrives behind the position of breach 181b, between the light accepting part 191b of lock-in detection sensor 191 and illuminating part, between 191b, no longer have plug-in unit 192 for lock-in detection, thereby the signal of lock-in detection sensor 191 outputs changes the signal of expression " ON: transmissive state " into from representing the signal of " OFF: shading status ".And control part 120 changes into the signal (detect and change latch-release state into) of expression " ON: transmissive state " from representing the signal of " OFF: shading status " at the signal that 191 outputs of lock-in detection sensor detected, control CD-ROM drive motor 701 and stop operating.
Action when below describing an example and being converted to latch-release state from lock-out state.Figure 21 is that an example is converted to the action flow chart of latch-release state from lock-out state.Control part 120 just sends once inquiry every 10msec in this embodiment, requires the various sensor output signals (testing result) such as drawer handle detecting sensor 200, but the cycle of inquiry be not limited to 10msec, control part 120 can be inquired by any period.Whether the signal that as shown in figure 21, first control part 120 judges 200 outputs of drawer handle detecting sensor is from representing that the signal of " OFF: shading status " changes the signal (S1) of expression " ON: transmissive state " into.
When the signal of S1 judgement drawer handle detecting sensor 200 outputs is when representing that the signal of " OFF: shading status " changes the signal (S1 is) of expression " ON: transmissive state " into, control part 120 detects plate (not shown) and is pressed (S2).Then, control part 120, according to the signal of each recording chart detecting sensor 300 outputs, judges whether to occur paperboard (S3).
When paperboard occurs for S3 judgement (S3 is), control part 120 judges whether paperboard (S4) occurs in drawer unit 76.If paperboards (S4 is) occur judgement drawer unit 76, process that move to will be at the following S6 describing in detail.And if judgement is the part generation paperboard (S4's is no) beyond drawer unit 76, control part 120 is controlled the position of not shown display part demonstration generation paperboard or is removed paperboard method of operating, is used for notifying user (S5).Then, process and move to following S6.On the contrary, if paperboard (S3's is no) does not occur in above-mentioned S3 judgement, survey processing and directly move to S6.
In S6, control part 120 judges whether in latch-release state according to the signal of lock-in detection sensor 191 outputs.When the signal indication of receiving from lock-in detection sensor 191 " ON: transmissive state ", control part 120 judgement drawer units 76 are in latch-release state (S6 is), end process.And when the signal indication being subject to from lock-in detection sensor 191 " OFF: shading status ", control part 120 is judged as still and is in the lock state (S6's is no), and then judges whether getting action actions such as (in comprising printing, adjusting) warming-ups ready (S7).
If action (S7 is) is being got in judgement ready in S7, control part 120 keeps lock-out state (S8), and end process.And if action (S7's is no) is got in judgement ready, control part 120 stops each load supplying (S9) carrying on drawer unit 76.Then, control part 120 judges whether CD-ROM drive motor 701 or drawer handle detecting sensor 200 occur abnormal (S10).
In S10, if abnormal (S10 is) appears in judgement CD-ROM drive motor 701 or drawer handle detecting sensor 200, control part 120 keeps lock-out state (S11), and end process.On the contrary, if judgement CD-ROM drive motor 701 or drawer handle detecting sensor 200 not abnormal (S10's is no), control part 120 unlocks state (being called in the following description " latch-release control ") (S12).
Figure 22 is the process flow diagram that a routine latch-release is controlled.As shown in figure 22, first, control part 120 is opened the driving (S20) of CD-ROM drive motor 701.Now as mentioned above, lock shaft 703 is along with the driving of CD-ROM drive motor 701 after rotating, live-rollers 162 moves to guide surface 186a and 186b from locking receiving face 182a and 182b, and under the guiding of guide surface 186a and 186b, moves to the position (removing traction) of breach 181a and 181b.
Then, control part 120 judges whether the signal of lock-in detection sensor 191 outputs is converted to " ON: transmissive state " (S21) from " OFF: shading status ".If the signal of lock-in detection sensor 191 outputs is converted to " ON: transmissive state " (S21 is) from " OFF: shading status ", when the turned position of judgement (detection) Lock Part 160 is converted to the second place from primary importance, control part 120 is carried out braking, stop the driving of CD-ROM drive motor 701, to keep the turned position of Lock Part 160 to remain on the second place (S22).Then, for example, after elapsed time T2 (T2=500msec), the braking that control part 120 is removed CD-ROM drive motor 701, stops to CD-ROM drive motor 701 power supplies (S23).
On the other hand, if judge in S21 that the signal of lock-in detection sensor 191 output is not converted to " ON: transmissive state " (S21's is no) from " OFF: shading status ", control part 120 further judgement CD-ROM drive motor 701 in S20 whether surpass T1 (for example T1=10000msec) (S24) working time from starting to drive.If surpass T1 (S24 is) working time of CD-ROM drive motor 701, control part 120 is controlled not shown display part demonstration maintenance service liaison method, for representing, breaks down, and the personnel that need repairing repair (S25).Then, control part 120 stops the driving of CD-ROM drive motor 701, and stops to CD-ROM drive motor 701 power supplies (S26).
