And with reference to the 17 (c) and 17 (d) Exemplary time profiles of signal levels of sensor signals presented by the optical sensor are shown 230 and the optical sensor 235 during insertion of the ink cartridge 10 ' be issued.

As in the 17 (a) and 17 (c) is the temporal profile of the signal level of the sensor signal, that of the optical sensor 235 is issued when the ink cartridge 10 in the tray 280 is attached, equal to the temporal profile of the signal level of the sensor signal, that of the optical sensor 235 is issued when the ink cartridge 10 ' in the tray 280 is attached. In particular, when the signal blocking section 191 in the optical path 236 of the optical sensor 235 when the light path is blocked or changed, the signal level changes from HIGH to LOW at time T1. In the main control 200 For example, this change of signal level from HIGH to LOW is used as a trigger signal in a workflow for determining the type of the ink cartridge.

With reference to the 17 (b) occurs the signal blocking section 189 in the optical path 231 and blocks or alters the light path at time T0 when the ink cartridge 10 in the tray 280 is attached. At this time, the signal level of the sensor signal, that of the optical sensor, changes 230 is output, from HIGH to LOW. Because the signal blocking section 189 a is flat plate, the time period within which the light is blocked or within which the path is changed, is relatively short. The signal blocking section 189 passes through the optical path 231 through and the room 190 enters the optical path after time T0 and before time T1. Therefore, at time T1, the signal level of the optical sensor became 230 restored from LOW to HIGH.

If below the ink cartridge 10 is further inserted, the cutout occurs 187 in the optical path 231 one, and, if the ink cartridge is completely in the tray 280 is attached, enters the translucent section 140 in the optical path 231 over the neckline 187 between a time T2 and a time T3. In this state, the signal blocking section 72 detected. In 17 (b) the signal level is represented by a solid line (LOW level) when the signal blocking section 72 in the optical path 231 lies. And the signal level is represented by a dashed line (HIGH level) when the signal blocking section 72 outside the optical path 231 located.

With reference to the 17 (d) occurs the signal blocking section 199 also in the optical path 231 to block the light or to change the light path at time T0 when the ink cartridge 10 ' in the tray 280 is attached. At this time, the signal level of the sensor signal, that of the optical sensor, changes 230 is output, from HIGH to LOW. Because the signal blocking section 199 the side walls 198 is the period of time during which the light passes through the signal blocking section 199 is blocked or changed longer than the time during which the light passes through the signal blocking section 189 blocked or changed. In particular, at the time T1, the side walls are located 198 still in the optical path 231 , Therefore, at time T1, the signal level of the sensor signal received from the optical sensor 230 is kept in the LOW state.

If below the ink cartridge 10 ' is pushed further, occur at time T2, the side walls 198 through the optical path 231 through, after which the cutout 187 in the optical path 231 entry. At this time, the signal level of the optical sensor 230 restored from LOW to HIGH. If after that, the ink cartridge 10 ' completely in the compartment 280 is attached, enters the translucent section 140 in the optical path 231 over the neckline 187 at a time between times T2 and T3. In this state, the position of the signal blocking section 72 be detected. In 17 (d) the signal level is represented by a solid line (LOW level) when the signal blocking section 72 in the optical path 231 lies. And the signal level is represented by a dashed line (HIGH level) when the signal blocking section 72 outside the optical path 231 lies.

The type of ink cartridge is controlled by the main controller 200 based on the time profiles of the optical sensor 230 and the optical sensor 235 certainly.

Regarding 18 FIG. 12 is a process of determining whether the attached ink cartridge is the ink cartridge 10 or the ink cartridge 10 ' is presented, layed out. In step S1, the main controller determines 200 whether the signal blocking section 189 or 199 in the optical path 231 of the optical sensor 230 occurred, z. For example, it is determined whether the signal level of the sensor signal received from the optical sensor 230 was issued, changed from HIGH to LOW or not. If the main controller 200 determines that the signal blocking section 189 or 199 the optical path 231 Step S2 is executed. The step S2 is not executed until the main controller 200 determines that the signal blocking section 189 or 199 in the optical path 231 occurred.

In step S2, the main controller determines 200 whether the signal blocking section 191 in the optical path 236 occurred, z. For example, it is determined whether the signal level of the optical sensor 235 is changed from HIGH to LOW or not, which corresponds to a detection of a trigger signal. If the trigger signal has been detected in step S2, the main controller determines 200 in step S3, whether the signal level of the optical sensor 230 outputted sensor signal at time T1, in which the trigger signal was detected, is HIGH or LOW. For example, the main controller determines 200 in the case where the signal level at the time T1 is HIGH that the ink cartridge 10 in the tray 280 was inserted, and the main controller determines that the ink cartridge 10 ' in the tray 280 was attached when the signal level at time T1 is LOW.

If it has been determined that the signal level of the sensor signal coming from the optical sensor 230 is high in step S3, then is in a register, for example, a register of the CPU 201 , in step S4 set a bit flag indicating that the installed ink cartridge of the ink cartridge 10 equivalent. If a bit flag was previously set, indicating that the installed ink cartridge of the ink cartridge 10 ' corresponds, then the bit flag indicating that the installed ink cartridge of the ink cartridge 10 ' is reset, after which the bit flag indicating that the installed ink cartridge is the ink cartridge 10 corresponds, is set. On the other hand, if it has been determined that the signal level of the sensor signal received from the optical sensor 230 is issued, is LOW, then the bit flag is set in the register in step S5, indicating that the installed cartridge of the ink cartridge 10 ' equivalent. If the bit flag indicating that the ink cartridge installed is the ink cartridge 10 has been previously set, then the bit flag indicating that the installed ink cartridge of the ink cartridge 10 is reset, after which the bit flag indicating that the installed ink cartridge is the ink cartridge 10 ' corresponds, is set. If the bit flag has been set, the recorder will show 250 or an information processing device such as one with the recording apparatus 250 connected personal computer (PC) based on the flag on which of the ink cartridges 10 or 10 ' was inserted.

When the signal level of the optical sensor 235 from LOW to HIGH, the determination procedure can be restarted. Further, the determination operation can be carried out as soon as the lock lever 283 is opened, after which the determination operation can be completed when the lock lever 283 is closed.

The type of ink cartridge 10 or 10 ' is based on the signal level of the sensor signal received from the optical sensor 230 is output at time T1, determines when the trigger signal is detected. Therefore, the structure of the ink cartridge allows 10 or 10 ' the recording device 250 , the type of ink cartridge 10 or 10 ' accurately and independently of the speed with which the user determines the ink cartridge 10 or 10 ' regardless of whether the user begins by inserting the ink cartridge into the printer and then partially removing it before finally inserting it completely into the printer.

The workflow described above is established between two types of ink cartridges 10 and 10 ' however, three or more types of ink cartridges can be distinguished. Further, an ink cartridge containing black ink and an ink cartridge containing color ink other than the black ink may be distinguished from each other. Also, an ink cartridge containing a pigment ink and an ink cartridge containing a dye ink may be discriminated.

Regarding 19 is a packaging arrangement 230 according to an embodiment of the present invention. The packaging arrangement 230 includes an ink cartridge, e.g. B. the ink cartridge 10 (or 10 ' ), as well as a packaging element 231 , The ink cartridge 10 is in an interior of the packaging element 231 added. The ink cartridge 10 will be in the packaging arrangement 230 shipped and sold.

The interior of the ink chamber 100 is reduced in pressure to a pressure that is less than the atmospheric pressure by z. For example, a vacuum pump is used to charge an amount of in the ink within the ink chamber 100 to reduce dissolved air. The interior of the packaging element 231 is also reduced to a pressure which is less than the atmospheric pressure by z. For example, a vacuum pump is used to prevent air from entering the ink chamber through the films containing the side surfaces 45 and 46 cover.

The packaging element 231 is waterproof, but has some gas permeability. Therefore, air can enter the interior of the packaging element 231 occur when the packaging arrangement 230 is not used for an extended period of time. Nevertheless, there is a reduced volume of pressure in the interior of the packaging member 231 , wherein the interior of the packaging element 231 is maintained in a stable, reduced in pressure state for an extended period of time.

The packaging arrangement 230 is made as follows. The ink cartridge 10 becomes in the interior of the packaging element 231 received in a state in which the movable element 21 in the first (extended) position as in 2 B) is shown represented. While this condition is being maintained, the pressure in the interior of the packaging element 231 reduced to a pressure which is less than the atmospheric pressure, after which the packaging element 231 is sealed. Because the ink cartridge 10 in the packaging element 231 is received in this way, a pressure-reduced space of predetermined capacity between the front surface 41 of the main body 20 and the front wall 161 of the movable element 21 in the interior of the packaging element 231 educated. Therefore, the inside of the packaging element becomes 231 held in the pressure-reduced state for an extended period of time.

Nevertheless, a pressure difference between the atmospheric pressure and the pressure inside the packaging member can 231 become so big when the interior of the packaging element 231 Too much pressure will cause a relatively large force on the ink cartridge 10 acts. In this case, if the pressure-reduced space between the front surface 41 of the main body 20 and the front wall 161 of the movable element 21 is formed, the movable element 21 deform inward and may not be restored to its original form. Thus, according to another embodiment of the present invention, the ink cartridge 10 ' in the packaging element 231 received in a state in which the movable element 21 in the second (retracted) position as in 2 (c) is shown represented. When the movable element 21 in the second position, the pressure-reduced space is between the front surface 41 of the main body 20 and the front wall 161 of the movable element 21 relatively low, so that therefore the deformation of the movable element 21 can be prevented. The size of the packaging arrangement 230 is also reduced. Because the pressure-reduced space still exists, although it is comparatively small, the inside of the packaging element becomes 231 held in a stable, pressure-reduced state for a considerable period of time.

With reference to the 20 and 21 is a cartridge attachment section 1276 according to another embodiment of the present invention. The cartridge attachment section 1276 includes a locking lever 1283 instead of the locking lever 283 the cartridge attachment section 276 , The locking lever 1283 includes a first section 1291 , a second section 1292 , as well as a rotary section 1290 between the first section 1291 and the second section 1292 , The rotary section 1290 is at the top section of the tray 280 adjacent to the opening 284 stored so that the locking lever 1283 around the rotary section 1290 can turn. The first paragraph 1291 extends from the rotary section to the outside of the compartment 280 , and the second section 1292 extends from the rotary section 1290 to the storage chamber 282 , The first paragraph 1291 is above the second section 1292 positioned because the weight of the first section 1291 less than the weight of the second section 1292 , As in 20 is shown, contacts a part of the second section 1292 a part of the latching recess 1000 if the ink cartridge 10 in the cartridge mounting portion 1276 will be installed. The main body 20 the ink cartridge 10 takes the compressive force of the coil springs 23 and 24 on the opening 284 on. Because still the part of the second section 1292 the part of the locking recess 1000 contacted to the main body 20 in the subject 280 against the compressive force of the coil springs 23 and 24 to hold, the ink cartridge remains 10 in the subject 280 ,

If a user intends to use the ink cartridge 10 from the cartridge attachment section 1276 To remove, the user exerts a downward force on an end portion of the first section 1291 out. The locking lever 1283 then turns around the rotary section 1290 , as in 21 is shown, after which the second section 1292 moves upwards and from the latching recess 1000 separates. Consequently, the coil springs stretch 23 and 24 off, and the ink cartridge 10 becomes partially out of the cartridge attachment section 1276 ejected. The user then grips the rear portion of the ink cartridge 10 and remove the ink cartridge 10 from the cartridge attachment section 1276 , Thereby, the ink cartridge easily becomes out of the cartridge mounting portion 1276 removed. Because beyond the ink cartridge 10 not adapted to the movable element 21 by itself keeping in the second position, the movable element moves 21 free from the second position to the first position as soon as the second section 1292 from the latching recess 1000 separates, with the ink cartridge 10 partly from the cartridge attachment section 1276 is ejected.

Referring to 22 (a) and 22 (b) is a distance D1 between the center line of the signal blocking section 191 and the signal blocking section 189 the ink cartridge 10 or between the signal-blocking section 191 and the signal blocking section 199 the ink cartridge 10 ' in the height direction, as by the arrow 32 is designated, 32 mm to 35 mm. A distance D2 between a front end of the signal blocking section 191 and a front end of the signal blocking portion 189 the ink cartridge 10 or between a front end of the signal blocking section 191 and a front end of the signal blocking portion 199 the ink cartridge 10 ' in the depth direction, as by the arrow 33 is designated, is -4.7 mm to 7.6 mm. In other words, the leading end of the signal blocking section 191 is 7.6 mm or less in front of the front end of the signal blocking section 189 or 199 positioned in the depth direction, or the front end of the signal blocking section 191 is 4.7 mm or less behind the front end of the signal-blocking section 189 or 199 positioned in the depth direction.

While the invention has been described in conjunction with exemplary embodiments, it will be readily understood by those skilled in the art that other modifications and variations of the exemplary embodiments may be made as described above without departing from the scope of the invention. Other embodiments will be apparent to those skilled in the art from consideration of the specification or implementation of the invention as disclosed herein. It is intended that the description and the examples described are considered to be merely exemplary of the invention. The true scope of the invention is indicated by the following claims.

It is to be understood that the term "signal blocking", as used herein, not just the reduction in signal intensity to zero, but sufficient for a reduced level lower for the signal-blocking section that he is can be detected. In this regard, although it is preferable that 100% intensity signal is prevented by the Signal blocking section to go, even a reduced intensity is allowed to go through and the intensity drop is detected.
