Description

  The present invention relates to a printing apparatus, a printing material cartridge, a circuit board, and an adapter.

  The printing material cartridge mounted on the printing apparatus is equipped with, for example, a storage device in which the model number and manufacturing number of the printing material cartridge are recorded, and a piezoelectric sensor for detecting the presence or absence of liquid as the printing material. (For example, refer to Patent Document 1). The presence / absence of liquid can be detected according to a residual waveform generated by residual vibration after electrostriction by applying a predetermined voltage waveform to the piezoelectric sensor.

  However, if the printing material cartridge is not properly installed in the printing device, a misalignment occurs between the terminal on the printing device side and the terminal on the printing cartridge side, and the storage device cannot be accessed correctly. There is a possibility that a voltage waveform cannot be applied to the sensor. These problems are not limited to piezoelectric elements, but are common to printing material cartridges equipped with electrical devices and storage devices to which a high voltage is applied, and printing materials other than liquid (for example, toner) are contained. This was a problem that could occur in the printing material cartridge.

A second terminal having a contact portion that is connected and in contact with the second device-side terminal; and provided near the second terminal, and when the printing material cartridge is correctly mounted on the cartridge mounting portion And a third terminal that is electrically connected to the first terminal without having a contact portion that contacts the device-side terminal, and the detection unit has the printing material cartridge mounted on the cartridge mounting unit In state, based on the electrical conduction state of the first apparatus-side terminal and the second apparatus-side terminals, it detects the mounting state of the printing material cartridge, the printing device.

  In such a configuration, for example, in a state where the second device-side terminal is in contact with the third terminal due to displacement of the mounting position of the printing material cartridge in the cartridge mounting portion, bending of the device-side terminal, or the like, When the first terminal electrically connected to the third terminal comes into contact with the first device-side terminal, the first device-side terminal and the second device-side terminal become conductive. . Therefore, it is possible to check whether or not the printing material cartridge is properly mounted based on the electrical continuity between the first apparatus side terminal and the second apparatus side terminal.

Application Example 2 In the printing apparatus according to Application Example 1, the detection unit applies a predetermined voltage to the first apparatus-side terminal, and a voltage corresponding to the predetermined voltage is the second device. A printing apparatus that detects a mounting state of the printing material cartridge according to whether or not it is detected from an apparatus-side terminal.

A. First embodiment:
Hereinafter, embodiments of the present invention will be described based on several examples.
FIG. 1 is a perspective view schematically showing an internal structure of a printing apparatus as an embodiment of the present invention. In FIG. 1, for convenience of illustration, XYZ axes orthogonal to each other are drawn. The printing apparatus 1000 is driven by a main scanning feed mechanism that reciprocates the carriage 1030 connected to the driving belt 1060 in the main scanning direction (X direction) using a power of the carriage motor 1020 and a paper feed motor (not shown). A sub-scan feed mechanism that transports the print paper P in the sub-scan direction (Y direction) using the paper feed roller 1010, and a head that drives the print head 1050 provided in the carriage 1030 to eject ink onto the print paper P. And a drive mechanism. The printing apparatus 1000 further includes a control unit 1040 for controlling each mechanism described above. The control unit 1040 is connected to the carriage 1030 via a flexible cable 1070.

  The carriage 1030 includes a cartridge mounting unit 1100 and a print head 1050. The cartridge mounting unit 1100 is configured to be capable of mounting a plurality of cartridges, and is disposed on the upper side of the print head 1050. The cartridge mounting portion 1100 is also called a “holder”. In the example shown in FIG. 1, four cartridges can be mounted independently in the cartridge mounting unit 1100, for example, four types of cartridges of black, yellow, magenta, and cyan are mounted one by one. The mounting direction of the cartridge is the −Z direction (vertical downward direction). As the cartridge mounting unit 1100, a cartridge mounting unit that can mount cartridges of four or more colors can be used. A cover 1200 is attached to the cartridge mounting portion 1100 so as to be openable and closable. The cover 1200 can be omitted. An ink supply pipe 1080 for supplying ink from the cartridge to the print head 1050 is disposed on the print head 1050. A type of printing apparatus in which a cartridge exchanged by a user like the printing apparatus 1000 is mounted on the cartridge mounting unit 1100 on the carriage 1030 of the print head is referred to as an “on-carriage type”.

  FIG. 2 is a perspective view showing the configuration of the cartridge mounted on the cartridge mounting portion. The XYZ axes in FIG. 2 correspond to the XYZ axes in FIG. The cartridge 100 includes a housing 101, a substrate 200 (also referred to as “circuit board”), and a sensor 108 electrically connected to a predetermined terminal on the substrate 200. The sensor 108 is a known ink remaining amount sensor using a piezoelectric element, and is an electric device to which a relatively high voltage is applied.

  An ink chamber 120 that stores ink is formed inside the housing 101. The sensor 108 is a sensor for detecting the remaining amount of ink in the ink chamber 120. The casing 101 has a substantially rectangular parallelepiped shape as a whole. A lever 160 is provided on the first side surface 102 of the housing 101. The lever 160 is used when the cartridge 100 is attached to or detached from the cartridge mounting portion 1100. That is, when the user presses the lever 160, the cartridge 100 and the cartridge mounting portion 1100 can be mechanically engaged or disengaged. The lever 160 is provided with an engaging protrusion 162 for fixing the cartridge 100 to the cartridge mounting portion 1100. An ink supply port 110 that is connected to the ink supply pipe 1080 of the printing apparatus 1000 when mounted on the cartridge mounting unit 1100 is formed on the bottom surface 104 of the housing 101. In the state before use, the ink supply port 110 may be sealed with a film. A sloped substrate placement portion 105 is formed at a position where the first side surface 102 and the bottom surface 104 intersect (that is, the corner portion at the lower end of the housing 101). The substrate 200 is attached to the substrate installation unit 105. It is also possible to consider that the substrate installation unit 105 is provided in the vicinity of the lower end of the first side surface 102. An engagement protrusion 150 for fixing the cartridge 100 to the cartridge mounting portion 1100 is provided on the second side surface 103 that faces the first side surface 102. The first side surface 102 is a surface that faces the front side (−Y direction) when mounted on the printing apparatus 1000 (FIG. 1). Therefore, the first side surface 102 is also referred to as “front end surface” or “front surface”. The second side surface 103 is also referred to as “rear end surface” or “rear surface”. The mounting direction SD when the cartridge 100 is mounted on the cartridge mounting portion 1100 (FIG. 1) is the −Z direction (vertical downward direction).

  FIG. 3A shows the configuration of the surface of the substrate 200. The surface of the substrate 200 is a surface exposed to the outside when the substrate 200 is mounted on the cartridge 100. FIG. 3B shows the substrate 200 viewed from the side. A boss groove 201 for fixing the substrate 200 to a protrusion provided on the substrate installation portion 105 is formed at the upper end portion of the substrate 200, and a boss hole 202 is formed at the lower end portion of the substrate 200.

  An arrow SD in FIG. 3A indicates the mounting direction of the cartridge 100 to the cartridge mounting portion 1100. This mounting direction SD coincides with the mounting direction (−Z direction) of the cartridge shown in FIG. The substrate 200 has a storage device 203 on the back surface, and a terminal group including eleven terminals 210 to 294 is provided on the front surface. The storage device 203 is a non-volatile semiconductor memory that stores information (for example, ink remaining amount) of the cartridge 100, a model number, a manufacturing number, and the like of the cartridge 100. The terminals 210 to 290 are formed in a substantially rectangular shape, and are arranged so as to form two rows that are substantially perpendicular to the mounting direction SD. Of the two rows, the row on the near side in the mounting direction SD (the row located on the upper side in FIG. 3A) is called the upper row R1 (first row), and the row on the back side in the mounting direction SD (FIG. 3). The lower column in (A) is referred to as a lower column R2 (second column). Note that these rows R1 and R2 can also be considered to be rows formed by contact portions cp with device-side terminals provided on the printing device 1000 side.

Hereinafter, the terminals 210 to 240 forming the upper row R1 and the terminals 250 to 290 forming the lower row R2 are also called as follows.
<Upper row R1>
(1) Terminal 210 ... Mounting detection terminal 210
(2) Terminal 220 ... Reset terminal 220
(3) Terminal 230: Clock terminal 230
(4) Terminal 240 ... Mounting detection terminal 240
<Lower row R2>
(5) Terminal 250 ... high voltage terminal 250
(6) Terminal 260 ... Power supply terminal 260
(7) Terminal 270: Ground terminal 270
(8) Terminal 280 ... Data terminal 280
(9) Terminal 290 ... high voltage terminal 290

  The attachment detection terminals 210 and 240 are used when detecting the quality of electrical contact with the corresponding device side terminals. The mounting detection terminal 210 and the mounting detection terminal 240 are connected to each other through wiring in the substrate 200 (or the back surface of the substrate 200). A part of the wiring connecting the two mounting detection terminals 210 and 240 may be replaced with a resistor. The state in which the two terminals are connected by wiring is also referred to as “short-circuit connection” or “conductor connection”. A short-circuit connection by wiring is a connection state different from an unintended short circuit.

  The high voltage terminals 250 and 290 are terminals electrically connected to the sensor 108 in the cartridge 100 and are terminals to which a high voltage is applied from the printing apparatus 1000 side.

  Terminals 220, 230, 260, 270, and 280 are terminals electrically connected to the storage device 203 and are also referred to as “memory terminals”. The storage device 203 to which the memory terminal is connected does not have an address terminal, and includes the number of pulses of the clock signal input from the printing apparatus 1000 through the clock terminal 230 and the command data input from the printing apparatus 1000 through the data terminal 280. Based on this, the memory cell to be accessed is determined. Then, the data is received from the data terminal 280 or the data is transmitted from the data terminal 280 in synchronization with the input clock signal. A power supply voltage (for example, a rating of 3.3 V) and a ground voltage (0 V) are supplied from the printing apparatus 1000 to the power supply terminal 260 and the ground terminal 270, respectively. The reset terminal 220 is used to supply a reset signal from the printing apparatus 1000 to the storage device 203.

  In the present embodiment, a position shift detection terminal 292 close to the high voltage terminal 250 is provided at the left end of the lower row R2 of the substrate 200, and a position shift detection close to the high voltage terminal 290 is provided at the right end of the lower row R2. A terminal 294 is provided. That is, the position shift detection terminals 292 and 294 are provided at both ends of the lower row R2. In addition, since the width of the lower row R2 is wider than the width of the upper row R1, the position shift detection terminals 292 and 294 are arranged on the outermost side of the terminals provided on the substrate 200, respectively. I can say that. These misalignment detection terminals 292 and 294 are used to determine whether or not the cartridge 100 is properly mounted on the cartridge mounting portion 1100 based on the contact state with the device side terminals corresponding to the high voltage terminals 250 and 290. . The positional deviation detection terminal 292 is provided at a position closest to the high voltage terminal 250, and the positional deviation detection terminal 294 is provided at a position closest to the high voltage terminal 290. The high voltage terminal 250 is disposed between the positional deviation detection terminal 292 and the memory terminal (ground terminal 270), and the high voltage terminal 290 is disposed between the positional deviation detection terminal 294 and the memory terminal (data terminal 280). Is arranged.

  In this embodiment, the positional deviation detection terminal 292 is electrically connected to the reset terminal 220 of the memory terminals, and the positional deviation detection terminal 294 is electrically connected to the data terminal 280 of the memory terminals. ing. Since the misalignment detection terminal 292 only needs to be electrically connected to the reset terminal 220, it may be connected to a wiring connecting the reset terminal 220 and the storage device 203. Alternatively, the storage device 203 may be directly connected to a reset terminal pin. In addition, it may be directly connected to the internal wiring of the storage device 203 in the package of the storage device 203. Similarly, the position shift detection terminal 294 may be connected to a wiring connecting the data terminal 280 and the storage device 203, or may be directly connected to a data terminal pin included in the storage device 203. Further, it may be directly connected to the internal wiring of the storage device 203 in the package of the storage device 203.

  Each of the plurality of terminals 210 to 290 includes a contact portion cp that comes into contact with a corresponding terminal among the plurality of device-side terminals at the center thereof. The contact portions cp of the terminals 210 to 240 forming the upper row R1 and the contact portions cp of the terminals 250 to 290 forming the lower row R2 are alternately arranged to form a so-called staggered arrangement. . The terminals 210 to 240 forming the upper row R1 and the terminals 250 to 290 forming the lower row R2 are also arranged in a staggered manner so that the terminal centers are not aligned with the mounting direction SD. Is configured. Note that when the cartridge 100 is properly mounted in the cartridge mounting portion 1100, the apparatus-side terminal does not contact the position shift detection terminals 292 and 294, so that the position shift detection terminals 292 and 294 have no contact portion cp. Is not included.

  FIG. 4 is a perspective view of the contact mechanism 1400 provided in the cartridge mounting portion 1100. The contact mechanism 1400 is a member for electrically connecting the terminals 210 to 290 on the substrate 200 and a control circuit in the printing apparatus 1000. The contact mechanism 1400 is provided with a plurality of electric contact members 510 to 590. The plurality of electrical contact members 510 to 590 correspond to device side terminals corresponding to the terminals 210 to 290 of the substrate 200. However, a terminal corresponding to the positional deviation detection terminal 300 is not provided in the contact mechanism 1400. Each of the device side terminals 510 to 590 is formed of an elastically deformable member (elastic member), and biases the substrate 200 upward with the cartridge 100 mounted. Note that the center terminal 570 in the lower end row has a higher protruding height than the other terminals. Therefore, when the cartridge 100 is mounted in the cartridge mounting portion 1100, the terminal 570 comes into contact with the terminal of the board earlier than the other apparatus side terminals. In other words, among the terminals 210 to 290 (FIG. 3) of the substrate 200, the ground terminal 270 contacts the device side terminal earlier than the other terminals.

  FIG. 5 shows a state where the cartridge 100 is mounted in the cartridge mounting portion 1100. In this state, the device-side terminals 510 to 590 of the contact mechanism 1400 are pushed down by the substrate 200 of the cartridge 100, and the entire device-side terminals 510 to 590 bias the cartridge 100 upward. Further, the engagement protrusion 150 provided on the second side surface 103 of the cartridge 100 is inserted into the engagement hole 1150 of the cartridge mounting portion 1100. Further, the engagement protrusion 162 of the lever 160 provided on the first side surface 102 of the cartridge 100 is engaged with the lower surface of the engagement member 1160 of the cartridge mounting portion 1100. The lever 160 is made of an elastic material, and a bending stress is generated so as to return the lever 160 toward the right side in FIG. The engagement between the engagement protrusion 162 and the engagement member 1160 prevents the cartridge 100 from being pushed upward. When mounting the cartridge 100 in the cartridge mounting portion 1100, first, the engaging protrusion 150 provided on the first side surface 102 of the cartridge 100 is inserted into the engaging hole 1150 of the cartridge mounting portion 1100. Thereafter, when the front end side (front end face 102 side) of the cartridge 100 is pushed downward with the engaging protrusion 150 as a fulcrum, the engaging protrusion 162 of the lever 160 provided on the front end face 102 of the cartridge 100 is attached to the cartridge. Engagement with the lower surface of the engaging member 1160 of the portion 1100 completes the mounting.

  When the cartridge 100 is properly mounted, the device-side terminals 510 to 590 (FIG. 4) of the contact mechanism 1400 and the terminals 210 to 290 (FIG. 3) of the substrate 200 of the cartridge 100 are in good contact with each other. To do. The ink supply port 110 of the cartridge 100 is connected to the ink supply pipe 1080 of the print head 1050. However, when the cartridge 100 is inserted into the cartridge mounting portion 1100 in an inclined state, or the array of the device side terminals 510 to 590 is distorted or bent, the device side terminals 510 to 590 and the terminals on the substrate 200 are used. 210-290 may not contact correctly. Therefore, in this embodiment, whether or not the cartridge 100 is properly mounted is detected by the configuration and processing described below.

  FIG. 6 is a block diagram showing an electrical configuration of the substrate 200 of the cartridge 100 and the printing apparatus 1000. The printing apparatus 1000 includes a display panel 430, an operation panel 450, a power supply circuit 440, a main control circuit 400, and a sub control circuit 500. The sub-control circuit 500 includes a memory control circuit 501 and a sensor-related processing circuit 503 inside. The main control circuit 400 and the power supply circuit 440 are included in the control unit 1040 shown in FIG. 1, and the sub control circuit 500 is provided in the carriage 1030. Therefore, the control unit 1040 (the main control circuit 400 and the power supply circuit 440) and the sub control circuit 500 are connected via the flexible cable 1070 shown in FIG. The main control circuit 400 and the sub control circuit 500 correspond to the “detection unit” of the present application, and these can be collectively referred to as “control circuit”.

  The main control circuit 400 has a CPU 410 and a memory 420. The CPU 410 executes a predetermined control program stored in the memory 420, thereby realizing a printing function using the main scanning feed mechanism, the sub-scan feed mechanism, and the head drive mechanism. Further, the CPU 410 executes a predetermined control program stored in the memory 420 to realize a function of detecting the mounting state of the cartridge 100 in the cartridge mounting unit 1100. Specific processing contents (wearing state detection processing) for detecting the wearing state will be described later.

  The display panel 430 is a display device that displays various notifications such as the operation state of the printing apparatus 1000 and the mounting state of the cartridge 100 in accordance with instructions from the main control circuit 400. The operation panel 450 is an input device for accepting an operation related to printing or an operation related to the mounting operation of the cartridge 100 from the user.

  The power supply circuit 440 includes a first power supply 441 that generates a first power supply voltage VDD, and a second power supply 442 that generates a second power supply voltage VHV. The first power supply voltage VDD is a normal power supply voltage (rated 3.3 V) used in the logic circuit. The second power supply voltage VHV is a high voltage (for example, rated 42 V) used for driving the print head 1050 to discharge ink. These voltages VDD and VHV are supplied to the sub-control circuit 500, and are also supplied to other circuits as necessary.

  The memory control circuit 501 controls the writing and reading of data to and from the storage device 203 on the substrate 200 in accordance with an instruction from the main control circuit 400, and detects the mounting state of the cartridge 100 together with the sensor related processing circuit 503. And a function for performing (a wearing state detecting function). Device side terminals 520, 530, 560, 570 and 580 (FIG. 4) corresponding to the memory terminals 220, 230, 260, 270 and 280 on the substrate 200 are connected to the memory control circuit 501. In response to a command from the main control circuit 400, the memory control circuit 501 individually sets the device side terminals 520, 530, 560, 570, and 580 to three states of connection, grounding, and opening (high impedance). It has a switching function.

  The sensor-related processing circuit 503 includes device-side terminals 510 and 540 (FIG. 4) corresponding to the mounting detection terminals 210 and 240 on the substrate 200 and device-side terminals 550 and 590 (see FIG. 4) corresponding to the high-voltage terminals 250 and 290. And 4) are connected. In response to an instruction from the main control circuit 400, the sensor-related processing circuit 503 individually switches the device side terminals 510, 540, 550, and 590 to three states of connection, grounding, and open (high impedance). It has a function.

  The sensor-related processing circuit 503 detects a mounting state of the cartridge 100 together with the memory control circuit 501 in response to an instruction from the main control circuit 400 (mounting state detection function), and mounting detection terminals 210 and 240 on the substrate 200. And a function for detecting whether or not the cartridge 100 is mounted (mounting presence / absence detecting function) and a function for detecting the remaining amount of ink using the sensor 108 of the cartridge 100 (remaining capacity detecting function). The remaining amount detection function and the mounting presence / absence detection function are functions that are executed after the mounting state detection function detects that the cartridge 100 is normally mounted in the cartridge mounting unit 1100.

  In the mounting presence / absence detection function of the sensor related processing circuit 503, the sensor related processing circuit 503 applies a predetermined voltage to one of the mounting detection terminals 210 and 240 of the substrate 200, and determines whether the voltage is output as it is from the other. To detect. By doing so, it can be determined whether or not the cartridge 100 is mounted on the cartridge mounting portion 1100.

  FIG. 7 is a timing chart showing an example of a voltage waveform applied to the sensor 108 in the remaining amount detection function of the sensor related processing circuit 503. The sensor-related processing circuit 503 applies the liquid amount inspection signal DS to the high voltage terminal 250 (or the high voltage terminal 290) when detecting the remaining ink amount. Then, the liquid quantity inspection signal DS is supplied to one electrode of the piezoelectric element constituting the sensor 108. The maximum voltage of the liquid amount inspection signal DS is, for example, about 36V generated based on the second power supply voltage VHV, and the minimum voltage is about 4V. When the liquid quantity inspection signal DS is applied to the sensor 108, the piezoelectric element of the sensor 108 vibrates according to the remaining amount of ink in the cartridge 100, and the back electromotive voltage generated by the vibration is used as the liquid quantity response signal RS. To the sensor-related processing circuit 503 via the other high voltage terminal 290 (or the high voltage terminal 250). The liquid amount response signal RS includes a vibration component having a frequency corresponding to the vibration frequency of the piezoelectric element. The sensor-related processing circuit 503 can detect whether or not the remaining amount of ink is equal to or greater than a predetermined amount by measuring the frequency of the liquid amount response signal RS.

  FIG. 8 is a flowchart of the mounting state detection process for confirming whether or not the cartridge is properly mounted in the cartridge mounting portion. This mounting state detection process is a process executed by the CPU 410 of the main control circuit 400, and is mounted on the cartridge mounting unit 1100 when the printing apparatus 1000 is turned on or the cartridge 100 is replaced. This is executed for each cartridge 100. Note that whether or not the cartridge 100 has been replaced can be determined by accepting an operation to the effect that the replacement operation of the cartridge 100 has been completed from the user via the operation panel 450.

  When this mounting state detection process is started, first, the CPU 410 controls the sensor-related processing circuit 503 to place the device-side terminal 550 corresponding to the high voltage terminal 250 in a connected state, and a device corresponding to the high voltage terminal 290. The side terminal 590 is opened (high impedance state) (step S100).

  Subsequently, the CPU 410 controls the memory control circuit 501 to place the device-side terminal 520 corresponding to the reset terminal 220 in a connected state and open other device-side terminals except for the device-side terminal 520 and the device-side terminal 550. The state is set (step S105). The reason for opening the other device side terminals is to prevent an unintended voltage from entering the memory control circuit 501 and the sensor related processing circuit 503 through the terminals on the substrate. Note that, as shown in FIG. 3, a position shift detection terminal 292 is electrically connected to the reset terminal 220 on the substrate 200.

  Next, the CPU 410 controls the memory control circuit 501 to apply a predetermined voltage (for example, the first power supply voltage VDD) to the device-side terminal 520 connected in step S105 (step S110). Then, it is detected using the sensor related processing circuit 503 whether or not the voltage is output through the device side terminal 550 corresponding to the high voltage terminal 250 (step S115). If the cartridge 100 is not correctly mounted in the cartridge mounting portion 1100, the contact position of the device-side terminal 550 deviates from the original position of the high voltage terminal 250 and contacts the adjacent position shift detection terminal 292. Sometimes. Then, the voltage applied to the reset terminal 220 through the device side terminal 520 in step S110 may be output to the device side terminal 550 through the position shift detection terminal 292 electrically connected thereto. Therefore, when a voltage is detected through the device-side terminal 550 in step S115, the CPU 410 can determine that the mounting state of the cartridge 100 is abnormal. Therefore, in this case, the CPU 410 displays an error message for prompting remounting of the cartridge 100 on the display panel 430 (step S120), and abnormally ends the mounting state detection process.

  On the other hand, if no voltage is detected from the device-side terminal 550 corresponding to the high-voltage terminal 250 in step S115, the above-described series of device-side terminals 590 corresponding to the other high-voltage terminal 290 are subsequently described. The same processing as that described above is performed. Specifically, the CPU 410 controls the sensor-related processing circuit 503 to place the device-side terminal 590 corresponding to the high-voltage terminal 290 in the connected state and open the device-side terminal 550 corresponding to the high-voltage terminal 250 (high-level). (Impedance state) (step S125). Further, the CPU 410 controls the memory control circuit 501 to place the device side terminal 580 corresponding to the data terminal 280 in the connected state, and open the other device side terminals except for the device side terminal 580 and the device side terminal 590. (Step S130).

  Subsequently, the CPU 410 controls the memory control circuit 501 to apply a predetermined voltage (for example, the first power supply voltage VDD) to the device-side terminal 580 brought into the connection state in step S125 (step S135). It is detected using the sensor related processing circuit 503 whether or not the voltage is output through the device side terminal 590 corresponding to the high voltage terminal 290 (step S140). If the cartridge 100 is not correctly mounted on the cartridge mounting portion 1100, the contact position of the device-side terminal 590 is shifted from the original position of the high voltage terminal 290 and contacts the adjacent position shift detection terminal 294. Sometimes. Then, the voltage applied to the data terminal 280 through the device-side terminal 580 in step S135 may be output to the device-side terminal 590 through the position shift detection terminal 294 electrically connected thereto. Therefore, when a voltage is detected through the device-side terminal 590 corresponding to the high voltage terminal 290, the CPU 410 can determine that the mounting state of the cartridge 100 is abnormal. In this case, the CPU 410 displays an error message urging remounting of the cartridge 100 on the display panel 430 (step S120), and abnormally ends the mounting state detection process. On the other hand, if no voltage is detected through the device-side terminal 590 corresponding to the high voltage terminal 290, it can be determined that the cartridge 100 is correctly mounted on the cartridge mounting portion 1100. Therefore, in this case, the CPU 410 normally ends the mounting state detection process.

  In the printing apparatus 1000 according to the present embodiment described above, the misalignment detection terminals 292 and 294 that are electrically connected to the memory terminals 220 and 280 are disposed in the vicinity of the high voltage terminals 250 and 290 on the substrate 200, so that the memory The mounting state of the cartridge 100 can be confirmed based on the conduction state between the main body side terminals 520 and 580 corresponding to the terminals 220 and 280 and the main body side terminals 550 and 590 corresponding to the high voltage terminals 250 and 290. Therefore, after confirming that the cartridge 100 is properly mounted, it is possible to detect the remaining amount of ink using the sensor 108, access the storage device 203, and detect whether the cartridge 100 is mounted. As a result, malfunction of the storage device 203 due to poor contact between terminals, and application of a high voltage to the sensor 108 to the sensor 108 can be suppressed.

  In this embodiment, since the high voltage terminal is disposed between the position shift detection terminal and the memory terminal, the high voltage terminal and the position shift detection terminal are disposed adjacent to each other. Therefore, it is possible to accurately detect that the device side terminal corresponding to the high voltage terminal erroneously contacts the position shift detection terminal.

  Further, in this embodiment, the position deviation detection terminals 292 and 294 are provided on the substrate 200 without preparing a special signal line for confirming the mounting state of the cartridge 100, and this is simply connected to the memory terminal. It's okay. Therefore, the mounting state of the cartridge 100 can be efficiently confirmed by using an existing signal line while suppressing an increase in manufacturing cost.

B. Second embodiment:
In the first embodiment described above, a voltage is applied to the memory terminal on the substrate 200, and this is detected through the device side terminal corresponding to the high voltage terminal, thereby detecting the mounting state of the cartridge 100. . On the other hand, in the second embodiment, the mounting state of the cartridge 100 is detected by applying a high voltage to the substrate 200 through the high voltage terminal.

  FIG. 9 is a block diagram illustrating an electrical configuration of the printing apparatus 1000 according to the second embodiment. In FIG. 9, the same components as those shown in FIG. 6 are denoted by the same reference numerals. As shown in FIG. 9, in this embodiment, an overcurrent detection circuit 505 is provided in series on the wiring between the sensor-related processing circuit 503 and the device-side terminal 550 of the sub-control circuit 500. An overcurrent detection circuit 506 is provided in series on the wiring between the processing circuit 503 and the device side terminal 590. The overcurrent detection circuits 505 and 506 are circuits for monitoring the current flowing from the sensor-related processing circuit 503 to the device side terminal 550 or the device side terminal 590, and preventing the overcurrent from flowing due to the application of the voltage. .

  FIG. 10 is a flowchart of the wearing state detection process executed in the second embodiment. When this mounting state detection process is started, first, the CPU 410 controls the sensor-related processing circuit 503 to place the device-side terminal 550 corresponding to the high voltage terminal 250 in a connected state, and a device corresponding to the high voltage terminal 290. The side terminal 590 is opened (high impedance state) (step S200). Then, the memory control circuit 501 is controlled so that the device-side terminal 520 corresponding to the reset terminal 220 is grounded, and other device-side terminals other than the device-side terminal 520 and the device-side terminal 550 are opened ( Step S205).

  Next, the CPU 410 controls the sensor related processing circuit 503 to apply a high voltage (for example, the second power supply voltage VHV) to the device side terminal 550 corresponding to the high voltage terminal 250 (step S210). Then, it is determined whether or not an overcurrent is detected by the overcurrent detection circuit 505 (step S215). When a high voltage is applied to the device-side terminal 550, if the device-side terminal 550 is in contact with the position shift detection terminal 292 instead of the high voltage terminal 250, the reset electrically connected to the position shift detection terminal 292 An overcurrent may flow through the terminal 220 and the device-side terminal 520 that is grounded. Therefore, if an overcurrent is detected in step S215, it can be determined that the mounting state of the cartridge 100 is abnormal. Therefore, the CPU 410 displays an error message for prompting the re-mounting of the cartridge 100 on the display panel 430 (step S220), and abnormally ends the mounting state detection process.

  On the other hand, if no overcurrent is detected by the overcurrent detection circuit 505 in step S215, then overcurrent detection using the other overcurrent detection circuit 506 is performed. Specifically, first, the CPU 410 controls the sensor-related processing circuit 503 to place the device-side terminal 590 corresponding to the high voltage terminal 290 in a connected state and open the device-side terminal 550 corresponding to the high voltage terminal 250. (High impedance state) is set (step S225). Further, the CPU 410 controls the memory control circuit 501 to place the device side terminal 580 corresponding to the data terminal 280 in the ground state, and open the other device side terminals excluding the device side terminal 580 and the device side terminal 590. (Step S230).

  Subsequently, the CPU 410 controls the sensor related processing circuit 503 to apply a high voltage (for example, the second power supply voltage VHV) to the device-side terminal 590 corresponding to the high voltage terminal 290 (step S235). Then, it is determined whether or not an overcurrent is detected by the overcurrent detection circuit 506 (step S240). When a high voltage is applied to the device side terminal 590, if the device side terminal 590 is in contact with the position shift detection terminal 294 instead of the high voltage terminal 290, the data electrically connected to the position shift detection terminal 294 An overcurrent may flow through the terminal 280 and the device-side terminal 580 that is grounded. Therefore, if an overcurrent is detected in step S240, it can be determined that the mounting state of the cartridge 100 is abnormal. Therefore, the CPU 410 displays an error message for prompting the re-mounting of the cartridge 100 on the display panel 430 (step S220), and abnormally ends the mounting state detection process. On the other hand, if no overcurrent is detected by the overcurrent detection circuit 506 in step S240, it can be determined that the cartridge 100 is correctly mounted in the cartridge mounting portion 1100. Therefore, in this case, the CPU 410 normally ends the mounting state detection process.

  According to the second embodiment described above, the cartridge 100 is mounted by checking whether or not an overcurrent flows by applying a high voltage to the device side terminal corresponding to the high voltage terminal on the substrate 200. It becomes possible to detect the state. In this embodiment, the overcurrent detection circuits 505 and 506 are provided separately from the sensor-related processing circuit 503. However, the sensor-related processing circuit 503 includes the overcurrent detection circuits 505 and 506. It is good also as composition which has. In this embodiment, a high voltage is applied to the substrate 200. However, the value of the voltage is arbitrary, and a lower voltage may be applied if an overcurrent can be detected.

C. Variations:

・ Modification 1:
In the above embodiment, the two misalignment detection terminals 292 and 294 are provided at both ends of the lower row R2 on the substrate 200, respectively. However, the disposition detection terminals 292 and 294 may be arranged in other modes. For example, as shown in FIG. 11, position shift detection terminals 292a and 294a may be provided at both ends of the upper row R1 on the substrate 200a. In addition, as shown in FIG. 12, misalignment detection terminals 292b and 294b may be provided so as to surround the high voltage terminals 250 and 292 on the substrate 200b, respectively. In addition, for example, it can be arranged between the memory terminal and the high voltage terminal.

In the above-described embodiment, the example in which the two positional deviation detection terminals 292 and 294 are provided on the substrate 200 is shown, but one of these may be omitted. Further, three or more positional deviation detection terminals may be provided in the vicinity of the high voltage terminal, and these may be electrically connected to the memory terminal. These misregistration detection terminals may be connected to different memory terminals or may be connected to a common memory terminal.

-Modification 4:
FIG. 13 is a diagram illustrating a modified example of the substrate 200. FIG. 13 shows a common substrate 200g that can be used in common for the four cartridges mounted on the cartridge mounting portion 1100. The common substrate 200g has a shape in which four small substrate portions 301 to 304 corresponding to four cartridges are connected by a connecting substrate portion 305. A gap G for straddling a rib provided in the cartridge mounting portion 1100 exists between the plurality of small substrate portions 301 to 304. In each small board portion, the respective terminals 210 to 294 are arranged in the same arrangement as the terminals on the board 200 shown in FIG. In addition, it is also possible to arrange | position each terminal in the arrangement | positioning shown in FIG.11 and FIG.12 in each small board | substrate part, and it is also possible to employ | adopt a different arrangement | positioning for every small board | substrate part.

  If this common substrate 200g is mounted on the cartridge mounting portion 1100 shown in FIG. 1, the four terminal groups of the common substrate 200g and the device side terminal group for four cartridges in the cartridge mounting portion 1100 are connected simultaneously. be able to. When the common substrate 200g is used, the ink container (ink container) can be mounted on the cartridge mounting unit 1100 separately from the common substrate 200g. It is also possible to install a plurality of ink containers at positions other than the cartridge mounting portion 1100 and supply ink from these ink containers to the print head 1050 of the carriage 1030 via a tube. In addition, the common substrate 200g can be used for a multi-color integrated cartridge in which the inside of one ink container is divided into a plurality of ink storage chambers that store a plurality of ink colors.

  As described above, even when the common substrate 200g is used, it is possible to detect the mounting state for each small substrate portion by using the position shift detection terminals provided on the individual small substrate portions individually. . In the present application, the term “substrate” simply refers to a substrate member corresponding to one cartridge mounting position (one receiving slot) in the cartridge mounting portion. That is, in the case of FIG. 13, each of the plurality of small substrate units 301 to 304 corresponds to a “substrate”.

They may be arranged in two rows along a direction parallel to the direction. Moreover, it may be divided into three or more rows instead of two rows. Further, the types and arrangement of the plurality of terminals for the storage device can be variously modified other than the above. For example, the reset terminal can be omitted.

Modification 6:
In each of the above embodiments, the sensor 108 having a piezoelectric element is used as a high voltage device mounted on the cartridge. However, the high-voltage device is not limited to this, and any device may be used as long as a voltage higher than the power supply voltage (operating voltage) of the storage device 203 is applied from the printing apparatus 1000. For example, instead of the sensor 108, a resistor having a predetermined resistance value may be mounted. In this way, if a resistor is mounted between the high voltage terminal 250 and the high voltage terminal 290 of the cartridge, the current value of the current flowing through the resistor is measured, so that the cartridge on the printing apparatus 1000 side can be measured. It is possible to determine the presence or absence or type. In this case, it is preferable to confirm the mounting state of the cartridge by the mounting state detection process in each embodiment described above before determining the presence or type of the cartridge using the resistor. In addition to the resistor, the high voltage device may include a device group including a light emitting element such as an LED.

Modification 7:
In each of the above embodiments, the ground terminal 270 of the storage device 203 is connected to the memory control circuit 501. However, the ground terminal 270 may be directly connected to the ground potential in the printing apparatus 1000 instead of the memory control circuit 501.

This cartridge 100c is compatible with the cartridge 100 of FIG. The ink storage unit 100Bc has an ink chamber 120Bc for storing ink and an ink supply port 110c. The ink supply port 110c is formed on the bottom surface of the housing 101Bc and communicates with the ink chamber 120Bc.

In a state where the ink storage unit 100Bc is stored in the adapter 100Ac, the ink supply port 110c of the ink storage unit 100Bc is connected to the ink supply pipe 1080 of the cartridge mounting unit 1100. In the vicinity of the lower end of the first side surface 102c of the adapter 100Ac, a sloped substrate placement portion 105c is formed, and the substrate 200 is placed on the substrate placement portion 105c. An engagement protrusion 150c is provided on the second side surface (rear end surface) 103c opposite to the first side surface 102c.

  When this cartridge 100c is used, both are mounted on the cartridge mounting portion 1100 simultaneously with the ink storage portion 100Bc combined with the adapter 100Ac. Alternatively, the adapter 100Ac may be first mounted on the cartridge mounting unit 1100, and then the ink storage unit 100Bc may be mounted in the adapter 100Ac. In the latter case, only the ink container 100Bc can be detached while the adapter 100Ac is mounted on the cartridge mounting unit 2100.

  FIG. 15 is a perspective view showing a second mode of separating the ink chamber from the cartridge. This cartridge 100d is also separated into an ink containing portion 100Bd and an adapter 100Ad.

It consists of and. The main difference from the cartridge shown in FIG. 14 is that in the adapter 100Ad shown in FIG. 20, there are members constituting two side surfaces (the largest side surfaces) intersecting the first and second side surfaces 102d, 103d and the bottom surface 104d. It is a point not to do. A lever 160d is provided on the first side surface 102d, and an engagement protrusion 162d is formed on the lever 160d. An engagement protrusion 150d is also formed on the second side surface 103d. The ink storage unit 100Bd has an ink chamber 120Bd that stores ink and an ink supply port 110d. This cartridge 100d can also be used in substantially the same manner as the cartridge 100c of FIG.

  FIG. 16 is a perspective view showing a third mode for separating the ink chamber from the cartridge. The cartridge 100e is also separated into an ink storage portion 101Be and an adapter 100Ae. The adapter 100Ae includes a first side surface 102e, a second side surface 103e facing the first side surface 102e, a third side surface 107e provided between the first and second side surfaces 102e, 103e, It is composed of a sloped substrate mounting portion 105d provided in the vicinity of the lower end of the first side surface 102d. The ink storage unit 100Be includes an ink chamber 120Be that stores ink and an ink supply port 110e. The bottom surface 104e of the ink container 100Be has substantially the same shape as the bottom surface 104a of the cartridge 100a shown in FIG. This cartridge 100e can also be used in substantially the same manner as the cartridges 100c and 100d of FIGS.

  As can be understood from the above-described examples of FIGS. 14 to 16, the cartridge can be separated into an ink container (also referred to as “printing material container”) and an adapter. In this case, the circuit board and the high voltage device are preferably provided on the adapter side.
