Abstract
Abstract A device having a motor and rollers for conveying a card inserted in the slot forward so as to read a magnetic stripe of the card. A system is used for feeding a carriage between the waiting position and the reading/writing position. The carriage embraces a contact pin head, which is longitudinally movable together with the carriage and vertically movable relative thereto, so that when the card is conveyed to reach the carriage in the waiting position the feeding system is automatically driven to feed the carriage and the contact pin head to the reading/writing position where the card is brought by the conveying motor components with holding engagement with the carriage to be electrically contacted at the contact points thereof with the contact pins of the head vertically moved up. Reliable reading/writing of the magnetic card as well as the IC card can be assured.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
228 words
A device for reading and writing data stored in a magnetic and/or IC card as an external memory, comprising; a substantially hexahedral casing which is formed with a slot in one wall thereof for manually inserting the card therethrough, means for conveying the partly inserted card forward to a position for reading/writing and rearward to the initial position to be manually removed, a magnetic head arranged in the vicinity of the slot to contact with magnetic stripe formed on the card, an electric contact head block adapted to contact with contact point arranged on the card conveyed to be in said reading/writing position, a carriage for embracing the contact head block and movable between a waiting position and the reading/writing position during which the contact head block is brought from a non-operation position to an operation position wherein contact pins of the contact head block are electrically contacted with the contact points of the card, and moved out of contact, said carriage being provided with a rack at a side surface thereof, and a pinion mounted in the casing to be driven for rotation and coming on meshing with the rack when the carriage is pushed forward by the card after the magnetic stripe of the card has been scanned by the magnetic head to convey the carriage to the reading/writing position together with the contact head block.
Claim 2
Independent Claim
228 words
A device for reading and writing data stored in a magnetic and/or IC card as an external memory, comprising; a substantially hexahedral casing which is formed with a slot in one wall thereof for manually inserting the card therethrough, means for conveying the partly inserted card forward to a position for reading/writing and rearward to the initial position to be manually removed, a magnetic head arranged in the vicinity of the slot to contact with magnetic stripe formed on the card, an electric contact head block adapted to contact with contact point arranged on the card conveyed to be in said reading/writing position, a carriage for embracing the contact head block and movable between a waiting position and the reading/writing position during which the contact head block is brought from a non-operation position to an operation position wherein contact pins of the contact head block are electrically contacted with the contact points of the card, and moved out of contact, said carriage being provided with a rack at a side surface thereof, and a pinion mounted in the casing to be driven for rotation and coming on meshing with the rack when the carriage is pushed forward by the card after the magnetic stripe of the card has been scanned by the magnetic head to convey the carriage to the reading/writing position together with the contact head block.
Claim 3
Dependent Claim
40 words
The device as set forth in claim 1, in which the movement rate of the carriage moved by meshing of the rack thereof with the pinion is made slower than the feeding speed for the card by the conveying means.
Claim 4
Dependent Claim
73 words
The device as set forth in claim 1, further comprising a sloped floor formed on the bottom wall of the casing, the sloped floor, during the movement of the contact head block from the non-operating position to the operation position, gradually raising the contact head block relative to the carriage to bring the contact pins of the contact head block to contact with the contact pints of the card at the uppermost position.
Claim 5
Dependent Claim
38 words
The device as set forth in claim 3, wherein said casing comprises a horizontally flat portion at the end of the upwardly sloped floor so that the contact head block may stably rest thereon in the reading/writing position.
Claim 6
Dependent Claim
34 words
The device as set forth in claim 1, in which the carriage is correctly held in the waiting position by abutting on a stopper to which the carriage is normally urged by spring means.
Claim 7
Dependent Claim
89 words
The device as set forth in claim 1, in which the conveying means comprises a pair of rollers to be rotatingly driven by a reversible motor via transmission gearings, one of the rollers being arranged in the vicinity of the slot while the other is arranged apart with a distance therebetween a little shorter than the length of the card so as to deliver the card from one roller to the other in the way of conveying so as to convey the card with frictional contact forward and rearward.
Claim 8
Dependent Claim
17 words
The device as set forth in claim 6, in which the reversible motor drives also the pinion.
Claim 9
Dependent Claim
202 words
The device as set forth in claim 6, further comprising four sensors along the passage on which the card is conveyed, a first sensor located in the vicinity of the slot and upstream a little from the first roller to detect the leading edge of the card manually inserted for energizing the motor to revolve in the regular direction and rotate the rollers to convey the card forward, a second sensor located at a portion downstream from said first roller so as to detect the card edge being conveyed rearward for deenergizing the motor as a result of which the card is gripped by the first pair of rollers to be partly protruded out of the casing slot, a third sensor located at a center of the card conveying passage so as to detect the trailing edge of the card located in the reading/writing position for energizing the motor to revolve in the reverse direction in reply to the additional signal generated when the reading/writing is over, and a fourth sensor located in the vicinity of the casing opposite end wall so as to detect the leading edge of the card brought to the reading/writing position for deenergizing the motor to stop.
