Puncher and method of controlling the puncher
First Claim
1. A card puncher comprising:
- means for storing data on a target quantity of conveyance of a card corresponding to a position where the card is punched;
means for conveying the card;
means for driving the conveying means by a quantity corresponding to the data on the target quantity of conveyance;
means for measuring a quantity of coast of the card after the drive of the conveying means by the drive means is terminated; and
means for punching the card if a sum of the target quantity of conveyance and the measured quantity of coast of the card is within an allowable limit.

Abstract
A card puncher for punching as a yardstick of use a card for getting coupon tickets on and used as tickets on omibuses and electric trains, and a method of controlling the card puncher. Data on a target quantity of conveyance of the card correponding to a position where the card is punched is stored in memory. A card conveyer is driven to convey the card by a quantity corresponding to data on the target quantity of conveyance stored in the memeory. A quantity of coast of the card after the drive of the card conveyer is teminated is measured. If the sum of the target quantity of conveyance and the measured quantity of coast of the card is within a predetermined allowable limit, the card is punched. If otherwise, data on the target quantity of conveyance in the memory is corrected such that the sum falls within the predetermined allowable limit, the card is returned to a position where the punching starts and the punching operation is retried.

9. A card puncher comprising:
-
a reversible motor; a conveyer belt driven by the motor for conveying a card to its target punching position; a mechanism for punching the card; an encoder rotated synchronously with the motor for outputting pulses proportional in number to the quantity of conveyance of the card; a sensor for sensing the passage of a leading or trailing end of the card through a predetermined position on the conveyer belt; a memory for storing data on a standard value indicative of the quantity of conveyance of the card from the predetermined position to the punching position where the card is punched, and data on a target position indicative of a quantity of conveyance of the card toward the punching position; a punching position counter for receiving the data on the target position from the memory when the leading or trailing end of the card is sensed by the sensor and sequentially updating the data on the target position with output pulses from the encoder; first control means for stopping the motor when the data on the target position in the punching position counter arrives at a predetermined value; a coast counter for measuring a quantity of coast of the card, after the motor is stopped, in accordance with output pulses from the encoder; and second control means for comparing the data on the standard value with the sum of the data on the target position and the data on the quantity of coast measured by the coast counter, directing the punching mechanism to punch the card if the error between the data on the standard value and the sum is within an allowable limit, correcting the data on the target position stored in the memory by a quantity corresponding to the error if the error is out of the allowable limit, driving the motor to return the card to the starting position of the punching operation, and causing the punching mechanism to retry the punching operation using the corrected data on the target position. - View Dependent Claims (10)

11. A method of controlling a card puncher comprising the steps of:
-
driving a card conveying means until a quantity of card conveyance arrives at a predetermined target quantity of conveyance corresponding to a position where a card is punched; measuring a quantity of coast of the card after the drive of the card conveying means is terminated; and punching the card if the sum of the target quantity of conveyance and the measured quantity of coast of the card is within a predetermined allowable limit. - View Dependent Claims (12, 13, 14, 15)
