INK CARTRIDGE AND RECORDING APPARATUS
First Claim
1. A member for maintaining contact between a plurality of electrodes of a circuit board and a plurality of elastic contacts of an ink jet recording apparatus, the member comprising:
- a body having a first side and a second side opposite from the first side;
a first projecting portion projecting from the first side away from the second side, the first projecting portion configured to be restricted by the ink jet recording apparatus in a vertical direction; and
a second projecting portion projecting from the first side away from the second side, the second projecting portion being disposed below the first projecting portion in the vertical direction and having a surface on which the circuit board is disposed.

Abstract
The ink cartridge includes an ink supply port formed at a position, offset to one side, of a wall configuring an ink container body; a positioning projecting portion, formed on one wall out of two opposing walls adjacent the wall, whose upper surface and side portion are regulated in position when the cartridge has been mounted on a recording apparatus; a lever, formed on the other wall out of the two walls, maintaining a normal hinged-open state and having a projection that is forcibly displaced outward when the cartridge is mounted on the recording apparatus; and electrodes that are connected to a memory unit storing information on the ink in an ink container and formed on the positioning projecting portion.

5. A member for maintaining contact between a plurality of electrodes of a circuit board and a plurality of elastic contacts of an ink jet recording apparatus, the ink jet recording apparatus including a cartridge holder having a bottom portion, a first wall surface extending from the bottom portion, a second wall surface extending from the bottom portion and opposing the first wall surface;
- and, a groove formed in the first wall surface;
a pair of ribs disposed on the second wall surface;
the plurality of elastic contacts being disposed on the second wall surface and between the ribs, the member comprising;
a first portion configured to be received by and engaged with the groove to prevent shifting in a widthwise direction when the member is mounted and disposed at a predetermined position in the cartridge holder;
a second portion disposed between and restricted by the ribs in the width direction, wherein the circuit board is disposed on the second portion so that the electrodes of the circuit board are in electrical contact with the elastic contact when the member is mounted and disposed at the predetermined position in the cartridge holder.
- and, a groove formed in the first wall surface;

6. A member for maintaining contact between a plurality of electrodes of a circuit board and a plurality of elastic contacts of an ink jet recording apparatus, the ink jet recording apparatus including a cartridge holder having a bottom portion, a first wall surface extending from the bottom portion, a second wall surface extending from the bottom portion and opposing the first wall surface;
- and, a pair of ribs disposed on the second wall surface;
the plurality of elastic contacts being disposed on the second wall surface and between the ribs, the member comprising;
a first portion configured to contact a region of the first wall to prevent shifting in a widthwise direction when the member is mounted and disposed at a predetermined position in the cartridge holder;
a second portion disposed between and restricted by the ribs in the width direction, wherein the circuit board is disposed on the second portion so that the electrodes of the circuit board are in electrical contact with the elastic contact when the member is mounted and disposed at the predetermined position in the cartridge holder.
- and, a pair of ribs disposed on the second wall surface;
