Definitions

  • a consumable cartridge namely an ink cartridge with such a control module, is also the subject of the invention.
  • printers for example inkjet printers
  • Replaceable disposable consumable containers so-called consumable cartridges
  • consumable cartridges are generally used to supply consumables.
  • ink cartridges are used for operation in corresponding cartridge receiving devices in the printer.
  • a consumable cartridge is empty, it is removed from the cartridge receiving device, discarded and replaced with a full cartridge or refilled with ink or toner.
  • ink cartridges with an electronic control module, for example with an electrically rewritable memory component (memory chip), which in turn comprises an array of memory cells for receiving the data content and a control logic (memory management circuit) for accessing the memory cells.
  • the control logic is connected to electrical contact elements, which are contact surfaces accessible from the outside. If the ink cartridge is inserted into a printer, the contact elements meet printer contacts, for example contact springs, which are mounted in the cartridge receiving device of the printer. These printer contact elements are internally connected to the control bus lines of the printer.
  • the supply voltage for the memory component and, on the other hand, data are transmitted from the printer via the control bus lines, usually according to a serial data transmission protocol.
  • the control logic is used to carry out input and output operations for data sent via the control bus into and from the memory cells.
  • the printer can read data from the memory component of the ink cartridge, for example on type, ink, color (ink color), etc., and data can be written to the memory, for example on the current remaining ink level.
  • a user can be informed at any time via a connected computer about the current ink level of an ink cartridge and, if necessary, be prompted to replace an ink cartridge that has been used up shortly.
  • EP 2 316 656 A1 an ink cartridge with a control module which has a memory component with control logic and memory cells.
  • the printer exchanges data with the memory component (memory array) via the control logic.
  • the control module has a plurality of contact elements which include power supply and data contact elements connected to the memory component, so-called first contact elements, as well as so-called second contact elements, which are used as detection contact elements (SN and SP) to determine whether the ink cartridge correctly in the cartridge holder of the Printer is used and all contact elements are electrically conductively connected to the corresponding printer contact elements.
  • the contact elements are arranged in rows next to one another.
  • a special feature of the control module described is that a contact element for supplying power to the control module (power supply contact element VDD) is arranged in a row between two detection contact elements. This is intended to achieve the advantage that the proper connection of the power supply contact element, which is particularly important for operating the control module, can be detected with particular reliability.
  • Another state of the art in DE 10 2011 003344 A1 discloses an ink cartridge which includes a battery that powers a storage section.
  • a mechanical switch on the ink cartridge controls power supply to the components of the ink cartridge by contacting or moving away from a wall surface of the mounting portion of the printer.
  • the invention is based on the motivation to provide a control module and a consumable cartridge (ink cartridge) with such a control module which reliably avoids short circuits between the supply voltage and the other contact elements and leads to higher functional reliability .
  • the invention proposes a control module and a consumable cartridge (ink cartridge or toner cartridge) with a control module of this type which has at least one switching element which is arranged in a power supply line between a power store and the memory component, wherein the switching element has a control input and depending on a control signal applied to this control input, the power supply line closes or interrupts, and the control input is connected to a contact element of the control module.
  • control module has an independent power supply for the memory component including control logic and memory cells. This makes it possible in principle to write data to the memory cells or to read them from them without the power supply contact element of the control module being connected to the printer. As a result, the power supply contact element on the control module can be omitted.
  • control module arises from the fact that the power supply of the memory component can be done autonomously, i.e. independently of the connection of the power supply contact element to the printer by the energy stored in the power storage unit: This means that the power supply contact element on the control module can simply be omitted without replacement. The probability of a short circuit with the other contact elements is correspondingly reduced.
  • the power supply of the memory component is only switched on by a control signal when data is actually to be exchanged between the printer and the control module. This is done via a control input, which is activated by the printer with a signal "activate control module" (chip enable) or “reset control module” (chip reset). The printer always emits such signals before data exchange begins.
  • the switching element according to the invention remains blocked, i.e. the power supply to the control module remains switched off.
  • This activation as required contributes to the fact that the current storage device according to the invention is only used for a short time, so it can be dimensioned with a relatively small capacity, for example in the form of a miniature battery (button cell) or a rechargeable battery or capacitor.
  • a semiconductor switch such as a transistor, preferably an FET (field effect transistor), preferably using MOS technology, is preferably used as the switching element.
  • a preferred embodiment of the control module provides that the shading element is connected to a timer circuit. This has the effect that the shaft element remains switched on for a specific, predetermined period of time after the occurrence of a control signal. This ensures that the control module remains switched on for a sufficiently long time for the data exchange, even if the control signal itself is only a short pulse.
  • a timer circuit can easily be implemented by a capacitor circuit with a capacitor that is used in parallel with the control input to ground.
  • control module is equipped with a power generation device.
  • a micromechanical generator can be provided that converts the movement of the print head into electrical energy during printing (“micro energy harvester"), or a photocell that converts light into electricity or the like.
  • the power storage device can be charged by the power generation device, so that it can be made smaller overall and also remains particularly functionally reliable for a long time.
  • Fig.1 shows a view of the front of a control module according to the invention.
  • FIG Fig. 2 The circuit of the control module 1 according to the invention is shown in FIG Fig. 2 shown schematically.
  • the memory component 3 is connected directly to the contact elements 11 (SCK) and 14 (SDA) via data lines, and via the ground connection to the ground contact element 13 (GND).
  • the power supply line 5 (VDD) of the memory component 3 is not connected to one of the contact elements mentioned, but via a switching element 6 to a power store 7, for example a battery or an accumulator.
  • the switching element 6 is designed as a MOS-FET, i.e. as a transistor switch whose control input 8 is connected to the contact element 10 (chip enable CE / reset RST).
  • the control input 8 is preceded by a timer circuit formed from the capacitor C, the resistors R1 and R2 and the diode D.
  • the control module 1 is activated when the printer emits a control pulse to the contact element 10, this is the case every time before a data transmission, i.e. the reading of data from or the writing of data to the memory component 3.
  • the control pulse reaches the Control input 8 of the switching element 6, so that it switches through and connects the power supply connection 5 (VDD) of the memory component 3 to the power store 7.
  • VDD power supply connection 5
  • FIG. 4 The circuit diagram of a control module 22 known in the prior art is shown, with the same reference symbols as in FIG Fig.1 used. This can only be powered by the printer. This results in the need to connect it continuously to the printer via a fixed line connection and a power supply contact element 16.
  • FIG. 3 A correspondingly designed control module 22 is shown in Fig. 3 shown. It can be clearly seen here how the power supply contact element 16 is arranged directly next to a detection contact element 12, as a result of which there is a risk of short circuits between the power supply contact element 16 and the detection contact elements 12, 15.
  • control module 1 In comparison to the known design of a control module 22 as in FIG Fig. 3 has that in Fig.1
  • the control module 1 according to the invention shown has the advantage that no power supply contact element (16 in Fig. 3 ) is available.
  • control module 1 can be connected to a consumable material cartridge, for example an ink cartridge 100 as in FIG Fig. 5 shown.
