Abstract:
A printing material container detachably attachable to a printing apparatus having apparatus-side terminals. The container can comprise an electrical device, a memory device and a plurality of terminals. First and second terminals can be coupled to the electrical device and a plurality of memory terminals can be coupled to the memory device. Terminal contact portions are present where the terminals contact a respective apparatus side contact forming member. A short detection contact portion can be positioned to contact a contact forming member that itself is coupled to a short detection circuit of the printing apparatus. The terminals can be arranged with the memory terminal contact portions located to the left of the second terminal contact portion and to the right of the first terminal contact portion. The contact portion that is second farthest to the right can be the third contact portion.
Abstract:
A system includes a plurality of storage devices and a controller. The plurality of storage devices are bus-connected to one clock signal line and one data signal line connected to the controller. Each of the plurality of storage devices stores identification information in advance to distinguish the storage devices from each other. The controller transmits data using an identification information transmission period in which one storage device is selected from the plurality of storage devices by transmitting the identification information of the one storage device to the plurality of storage devices via the data signal line and a data transmission period in which the data is transmitted to the one selected storage device. A frequency of a clock signal during the identification information transmission period is set to be lower than a frequency of the clock signal during the data transmission period.
Abstract:
A printing material container is detachably attachable to a printing apparatus having a plurality of apparatus-side terminals. The printing material container comprises a first device, a second device, and a terminal group that includes a plurality of first terminals, at least one second terminal and at least one third terminal. The plurality of first terminals are connected to the first device and respectively include a first contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one second terminal is connected to the second device and includes a second contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one third terminal is for the detection of shorting between the at least one second terminal and the at least one third terminal and includes a third contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one second contact portion, the plurality of the first contact portions, and the at least one third contact portion are arranged so as to form one or multiple rows. The at least one second contact portion is arranged at an end of one row among the one or multiple rows.
Abstract:
A storage device electrically connected to a host circuit includes a data receiving unit, determination unit, and a data transmitting unit. The data receiving unit receives data including first data which are to be written in a memory array and second data which are generated based on the first data from the host circuit. The determination unit determines consistency between the first data and the second data. The data transmitting unit transmits a result of the determination to the host circuit.
Abstract:
A mounting detection circuit of a printing apparatus outputs a first mounting inspection signal to one of first terminals and outputs a second mounting inspection signal to one of second terminals thereby performing a mounting inspection for determining whether or not printing materials are mounted depending on whether or not second mounting response signal is received, and examines at least one of whether or not the second mounting response signal is influenced by the first mounting inspection signal and whether or not a first mounting response signal is influenced by the second mounting inspection signal thereby performing a leakage inspection for determining whether or not there is a leakage between the first and second terminals.
Abstract:
A storage apparatus including a nonvolatile storage section and a control section controlling the nonvolatile storage section, wherein the control section has a detection circuit detecting floating state in at least one of power supply terminal connected to host side power supply terminal to which a power supply voltage is supplied from the host device, and ground terminal connected to host side ground terminal to which a ground voltage is supplied from the host device and a mask process section performing a mask process of the system clock that is used to control the nonvolatile storage section, wherein the mask process section masks the system clock if the floating state is detected by the detection circuit.
Abstract:
Control circuit 30 determines whether or not all ink cartridges CA1 through CA6 are attached in the home position based on cartridge out signals COO. Control circuit 30 carries out communication with memory devices 21 through 26 and determines the presence or absence of communication malfunctions. When a communication malfunction develops in one of memory devices 21 through 26, control circuit 30 determines if a communication malfunction is caused by ink cartridge 30 being detached and identifies detached ink cartridge CA using identifying information. When all of ink cartridges CA1 through CA6 are attached, control circuit 30 determines which of memory devices 21 through 26 has developed a communication malfunction and identifies ink cartridge CA in which a communication malfunction has developed using identifying information.
Abstract:
When the input write data is a value of a value greater than the existing data of the memory array 100, the semiconductor memory device enables writing of input write data to the memory array 100. In specific terms, the increment controller 150 reads the existing data from the memory array 100, and compares it with the write data latched to the 8-bit latch register 170. When the value of the write data is a value greater than the existing data, the increment controller 150 outputs the write enable signal WEN1 to the write/read controller 140, and executes writing of the write data latched to the 8-bit latch register 170 to the memory array 100.
