Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in the technical field of time recorders, and more specifically, a time card inserted in a time recorder is printed by a printer which is determined by reading an ID code. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time card stepping control method and apparatus for accurately stepping to a column position.

[0002]

2. Description of the Related Art A conventional method for feeding a time card to a determined printing step position is, for example, Jikken Sho 53-7.
As disclosed in Japanese Patent Publication No. 794, a mechanical type in which the position of a card receiving arm that receives the lower end of a time card is stepped upward or downward by mechanical means, for example, JP-B-63-62028. As disclosed in Japanese Unexamined Patent Publication No. JP-A No. 2003-242242, a motor type in which a time card can be stepped to a predetermined printing step position by controlling rotation of a card feeding roller using a motor, for example, Japanese Patent Publication No. As can be seen in Japanese Laid-Open Patent Publication No. 21953, by reading a step mark printed on a time card at a constant pitch with a sensor, it is possible to control a card feeding motor to advance a time card to a determined printing step position. There is a step mark reading system configured so as to be possible.

[0003]

However, in the case of the above-mentioned mechanical step feed method, the structure is complicated and the parts cost and the assembly cost are incurred. On the other hand, the printing step is determined by raising or lowering the card receiving arm step by step. However, there is a problem that complicated attendance records, such as printing various aggregated data item by item in a dedicated print field provided on the time card, cannot be performed.

Further, in the case of the above-mentioned motor type step feed method, although there is a degree of freedom to print various data on an arbitrary printing step of the time card by controlling the rotation of the motor, the step feed of the time card In order to accurately perform the operation according to the rotation of the motor, it is necessary to use a high-precision and high-priced motor such as a stepping motor as a card feeding motor, which has a problem of affecting the price of the entire time card. If the diameter of the card feed roller is incorrect due to processing error or wear, the card cannot be printed accurately on the specified printing stage even if the card is fed accurately using the stepping motor. There was also a problem.

Further, in the case of the above step mark reading system,
Since the step marks are printed on the time card at a constant pitch for the number of print steps and the print step is determined by reading the step marks, the print format is always the same, which meets the customer's request. There is a problem that it is very difficult to create a time card having a flexible print format.

Therefore, the technical problem of the present invention is that the degree of freedom in determining the printing stage is not lost and the program can be handled simply and accurately by simply changing the program, and the manufacturing cost can be reduced. The present invention is to provide a time card step feed control method and device for a time recorder capable of producing a time card of a flexible print format and speedily determining the print step position.

[0007]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows. In the time recorder configured to determine the printing stage by reading the ID code of each employee recorded on the time card, and the printer to print the work data on the determined printing stage,

(1) When the time card is retracted and conveyed by the rotation of the card feed motor, the step marks recorded at intervals above and below the time card are read to determine the distance between the upper and lower step marks and the number of steps of card feeding. The feed pitch per step of the card feed motor is calculated, the number of movement steps to the printing stage determined by the ID code is calculated based on the feed pitch, and the card feed motor is moved by the calculated number of movement steps. Rotate to feed the time card to the print column position.

(2) It is possible to read both the ID code recorded on one side of the time card on both sides of the time card transport path and the step marks recorded on the other side with a vertical gap between them. The first sensor and the second sensor that can be provided are vertically displaced from each other, and the controller connecting the first sensor, the second sensor, and the card feed motor has the above-mentioned upper and lower stages by the first sensor or the second sensor. Feed pitch calculation means for calculating the feed pitch per step of the card feed motor according to the reading of the mark, and the number of movement steps to the printing stage determined by the ID code based on the feed pitch calculated by this calculation means And the card feed motor is rotated by the number of movement steps calculated by this calculation means to move the time card to the print step position. And a motor control means for feeding.

[0010]

The above means operates as follows. Since the time feeding of the time card is performed by the card feeding motor according to the ID code recorded on the time card, the card feeding motor is controlled to feed the time card to an arbitrary printing stage position, thereby making it complicated to start counting. It is possible to print freely.

Each time the time card is inserted, the upper and lower step marks are read, the feed pitch per step by the card feed motor is calculated, and the number of movement steps is calculated based on the calculated feed pitch. Since the step feed can be performed accurately, it is not necessary to use a highly accurate and expensive stepping motor as the card feed motor, and it is possible to reduce the cost by using a relatively inexpensive AC motor or the like.

Each time the time card is inserted, the feed pitch per step is accurately calculated, and the time card is fed stepwise at the calculated feed pitch. Even if the time card is out of order or is out of order due to wear, it is possible to always feed the time card accurately to the predetermined print stage position.

Since the time card is step-fed based on the feed pitch calculated by reading the two upper and lower step marks, by using this feed pitch as a reference, work data, aggregate data, etc. can be placed at any position on the time card. Since it can be printed accurately, it is possible to create a time card with a flexible printing format that meets the needs of customers. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.

The moving step number calculation software for calculating the number of moving steps to the printing step determined by the above, and the card feeding motor 4M is rotated by the calculated number of moving steps to advance to the printing step position determined by the time card TC. The motor control software for doing so is built in so that the printer 5 can print the work data on the specified printing stage of the inserted time card TC. The printing procedure will be described in detail with reference to the flowcharts shown in FIGS. 6 and 7.

When the lower end of the time card TC into which the first sensor 1 is inserted is detected in step S1, the next step S1
2, the card feed motor 4M starts forward rotation, the time card TC with the conveyor belt 4V inserted therein is drawn downward and conveyed, and then the process proceeds to step S3 to proceed to the second sensor 2
When the lower edge of the time card TC that is sent is detected,
In the next step S4, the level of each sensor 1 and 2 is adjusted according to the surrounding environment or situation, and then in step S5, the step marks DMa and DMb recorded on the time card TC are recorded on the first sensor 1. A command to start reading is sent and the process proceeds to the next step S6. At this time, in the case of the first half of the month when the time card TC inserts the front surface TCA toward the front surface, the first sensor 1 indicates the lower step mark. The reading of the ID code BC is started without reading DMa.

In the next step S7, it is determined whether or not the second sensor 2 has started reading the step mark DMa or the ID code BC. If NO, the process returns to step S6 described above to read the first sensor 1. If the determination is YES, the process proceeds to the next steps S8 and S9, and the first sensor 1
And the reading of the step marks DMa and DMb and the ID code BC by the second sensor 2 is continued, and then step S10
Then, when the process proceeds to step S11 and the reading of each sensor 1 and 2 is completed, the process proceeds to the next step S12.

In step S12, it is determined whether or not the first sensor 1 detects the upper end of the time card TC. If it is detected, the process proceeds to the next step S13, the card feed motor 4M is stopped, and the time card TC is detected. While stopping the pulling-in / conveying of each sensor 1, the process proceeds to the next step S14, and each sensor 1
The number of steps of the card feed motor 4M between the lower mark DMa and the upper mark DMb and the ID code BC (bar code) are edited according to the data read by the above-mentioned Nos. 2 and 3, and the front and back side check of the time card TC and the edited ID are performed. The code is checked (specification) and the next step S
Proceed to 15.

In step S15, the distance from the lower mark DMa to the upper mark DMb of the time card TC = Am
The feed pitch Cmm / step (= A / B) per step of the card feed motor 4M is calculated from m (fixed) and the number of steps from the lower mark DMa to the upper mark DMb = B, and then the step In step S16, the length of the time card TC is checked according to the detection data of the lower end and the upper end of the time card TC by the first sensor 1, and the process proceeds to the next step S17 (see FIG. 7).

In step S17, it is determined whether or not the front and back of the time card TC have been correctly inserted based on the front and back discriminating data and the program checked in step S14. In the case of NG, the process proceeds to step S26 and the card feed motor 4M is directly operated. When the time card TC is discharged to the insertion slot by the reversal of No., and it is correct (YES), the process proceeds to the next step S18. If it is (first half), the process proceeds to step S20.

In step S19, the card feed motor 4
M is reversed to move the time card TC upward to a position where the first sensor 1 detects the upper mark DMb and stop, and in step S20, the card feed motor 4M is also reversed to move the time card TC to the second sensor. 2 moves up to a position where the upper mark DMb is detected and stops, so that these stop positions are respectively set as reference points and step S
Step shifting after 21 is performed.

That is, in step S21, the step S
The print position of this time is determined by collating the ID code determined in 14 with the work system program of the memory unit 11, then the process proceeds to the next step S22, and the feed pitch per step calculated in step S15 is used. , The number of movement steps of the card feed motor 4M from the reference point to the printing step position and its direction are calculated based on the distance from each stop point (reference point) to the determined printing step position, and the next step S23. By rotating the card feed motor 4M in the forward or reverse direction by the calculated number of movement steps to feed the time card TC in stages, the determined printing stage can be positioned on the print line PL of the printer 5. ..

After the above stepping is completed, step S24
In step S25, the printer 5 prints one line of work data in the print stage column Ta determined by the printer 5, and then in step S25, it is determined whether the printing is completed. If the printing is completed, the next step S26 is performed. Then, the processing for discharging the time card TC is performed by the reverse rotation of the card feed motor 4M.
If there is any other data to be printed, step S2
7, the number of steps up to the next printing stage is calculated, and thereafter, the processes of steps S23 and S24 described above are executed to end the printing process, and when all printing is completed, step S
The process proceeds to step 26, the time card TC is ejected, and all the processes are finished.

In the above-described embodiment, the reference point for calculating the number of movement steps is the detection point of the upper mark DMb, but this is an example of implementation and the time card T is used.
The lower end of C, the lower mark DMa, or any other position may be set as the reference point, and the selection is arbitrary.
