ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a time recorder with a card feed rate adjustment function making it possible to correctly print one's arrival or departure time in a print column by adjusting a card feed rate even when a card feed rate changes due to a processing error by or a seasonal change of a card carrier roller or when the print column changes due to shrinkage or extension of the time card as well as to a time card adapted to use in this time recorder.
PRIOR ART
The time recorder with a card feed rate adjustment function as described above is disclosed, for instance, in Japanese Patent Laid-Open Publication No. HEI 8-101935.
The time recorder disclosed in this publication has the configuration in which a test mark is provided on a maintenance card exclusively used for maintenance, and a mark sensor counts a number of pulses generated from an encoder, while this card is being fed, from a point of time when a lower edge of the card is detected by the card sensor until a point of time when the test mark is detected and compares this number of counted pulses to a preset standard number of pulses to calculate a correction value, and a time card is fed according to the number of pulses corrected according to this correction value.
PROBLEMS TO BE SOLVED BY THE INVENTION
In the conventional type of time recorder as described above, as a correction value for adjusting a card feed rate is computed by using a maintenance card exclusively used for adjustment which is completely different from a time card used for printing one's arrival or departure time, when a time card is actually inserted and the card is fed according to the correction value computed as described above, an error may occur in feeding the card, which in turn may disadvantageously make it difficult to correctly print the time data in a print column.
Namely, in the conventional technology, a maintenance card and a time card which is used daily are generally produced by different manufacturers through different production processes respectively, and even if the maintenance card and time card are produced based on the same specifications, there are usually some differences between the two types of cards, and especially a copy product may be produced and used as a time card, or those produced in different factories are sometimes used in the same time recorder, and in that case paper qualities of the cards may be different, and the cards extend or shrink from season to season, and therefore it is very difficult to uniformly control a feed rate of each of the time cards having different properties and characteristics respectively according to a correction value computed using the maintenance card, and as a result even though a feed rate for the cards is adjusted, sometimes the printed letters are sometimes partially or wholly off from the print column of each time card, which makes it disadvantageously difficult to beautifully print time and date within the print column.
Therefore a technological object of the present invention is to provide a time recorder with a card feed rate adjustment function capable of printing one's arrival or departure time to and from a job site always at a correct position within a print column by adjusting a feed rate of each time card according to such parameters as a paper quality or a degree of extension or shrinkage or a printing state within the print column.
Another technological object of the present invention is to provide a time card well adapted to use in the time recorder with a card feed rate adjustment function described above.
MEANS FOR SOLVING THE PROBLEMS
The technological objects described above can be achieved by the features of the present invention described below.
(1) The present invention provides a time recorder with the operation mode capable of being switched between a print mode and a set mode and feeding a time card inserted therein up to a data time data stamping step position for stamping a current date with a card carrier motor and stamping the date when the operation mode is switched to the print mode is set and also adjusting a feed rate for the time card when operation mode is switched to the set mode, and this time recorder comprises a sensor for reading a start point and an end point for measurement of a feed rate provided on an inserted time card, an encoder for counting a feed rate of the time card fed from a point of time when the start point is read until a point of time when the end point is read, an adjustment value computing means for computing an adjustment value for adjusting the feed rate by comparing the counted feed rate to a preset basic feed rate, and an adjustment value registration means for registering the computed adjustment value as step pitch adjustment data, each of which is each enabled when the operation mode of the time recorder is switched to the set mode, and the time recorder further comprises a feed rate control means for adjusting a feed rate of the time card by the card carrier motor according to the registered step pitch adjustment data to carry the time card to the time data stamping step position for the current data when the operation mode is the time recorder is set to the print mode.
