Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a time recorder that prints work data in a predetermined printing field of a time card using a printer driven by a motor, and particularly relates to a time recorder that prints work data in a predetermined printing field of a time card using a printer driven by a motor. The present invention relates to a print position control device for a time recorder that can easily handle changes in print field width.

[Conventional technology]

Currently used time cards include, for example, on-time attendance column, late arrival column, early leaving column, on-time leaving column, etc.
Various print columns such as an overtime column and a late night overtime column are displayed side by side. As a mechanism for printing on such time cards, a time recorder using a printer that is laterally moved by a motor has been proposed. In the case of this time recorder, the working data corresponding to the insertion time of the time card is determined based on setting data unique to each business office stored in the memory, and the working data printing control means controls the above-mentioned motor. The printer is moved to the corresponding printing column, and then the above employment data is printed in the corresponding printing column of the time card.

[Problem to be solved by the invention]

In this method of controlling the printer's print field position while moving the printer with a motor, the printer moves from the start while counting pulses of the rotation of the printer motor to control the printer's movement and determine the print field. A constant value of the driving rotational torque is very important. Therefore, an expensive so-called scanning motor such as a stepping motor, pulse motor, or synchronous motor must be used as the motor, which increases the cost of the entire device. It had the disadvantage of inviting Furthermore, with the above printing method, when changing and using timecards with different widths for each printing field, it is essential to change the program data stored in the memory, and therefore, each time the timecard is changed. There was a problem in that it was necessary to reprogram the program, and it was not possible to easily change the time card.

Another proposal is to fix the printer and automatically or manually slide the card pocket to determine the print position, but even with this method, if you change the time card, the print width or the card pocket will stop sliding. There was a problem in that the position, etc. had to be changed, and the process of making these changes was extremely complicated.

Therefore, the technical problem of the present invention is to easily follow the change in the width of the print field of a time card, and to use an inexpensive ordinary motor as a printer motor and a simple program to change the width of each print field. It is an object of the present invention to provide a printing position control device for a time recorder that can perform printing accurately.

[Means to solve the problem]

The measures taken in the present invention to solve the above technical problems are as follows.

Work data related to the insertion time of the time card is calculated based on the specified work time system data, and the calculated work data is printed in the specified printing field on the time card by a printing device using a printer that is moved by a drive motor. (1) A plurality of detection plates are moved and adjusted on a mounting rod installed parallel to the movement path of the printer in accordance with the separation positions of each printing column of the time card. Can be installed freely.

(2) The above printers must be equipped with a detector that detects and counts these detection plates.

(3) This detector has a control that detects the printer's movement position according to the count on the detection plate sent from the detector, and controls the printing operation of the printer based on the setting program stored in the memory. Connecting equipment.

[Effect]

The above means works as follows.

The factor (1) above is that if the time card specifications change and the width of each printing field changes, you can easily adjust the printer by simply moving and adjusting the mounting position of each detection plate according to this change. The printing position can be changed.

The factor (2) above is that the detector that moves with the printer detects and counts the number of detection plates and can accurately determine the moving position of the printer, so the drive rotation torque is not constant. To always accurately control the moving position of a printer even when using a motor.

The element (3) above detects the printer's movement position by the number of detection plates counted by the detector, so there is no need to program control the printer's movement by the drive motor, and the printer's printing To enable correct printing in each printing column of a time card by only controlling the operation by program.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.

A printing program as shown in FIG. 5 is set and stored in the program memory 31. That is, for the contents of each setting item, an address and a setting numerical value, which is data corresponding to this address, are stored. In the program data shown in FIG. 5, "column 1 movement time" to "column 6 movement time" are defined as follows, for example.

"Column 1 travel time" is stored in area A1, and this "Column 1 travel time" corresponds to the "on-time attendance column" of the time card, and the address "0200" is stored as setting data ""1:00" is set. Area A2 stores "column 2 travel time", and this "column 2 travel time" is stored in the "late column".

Next, the printing operation of the time recorder of the present invention will be explained with reference to flowcharts shown in FIGS. 6 and 7. These flowcharts represent part of the configuration of a system program stored in the memory 31 that defines the operation of the CPU 30.

First, when a one-minute pulse from the clock circuit 35 is given as an interrupt command to the CPU 30 via the interrupt signal line INT, the interrupt process shown in FIG. 6 is executed. In the first step S1 of this interrupt processing, clock data is updated. That is, the previously registered data of the month, day, hour, and minute stored in the clock register in the working memory 32 is updated by one minute. In the next step S2, the current time data (month, day, hour, minute) in the clock register is compared with the data for each work category stored in the processing status data register in the working memory 32. The contents of the processing status data register are updated according to the time data, and the interrupt processing is ended.

When the interrupt processing is completed, the routine returns to the normal processing routine shown in FIG. In the first step S3 of the normal processing shown in FIG. 7, the current time data of the clock register in the working memory 32 is supplied to the display device 42 and displayed on the display section 5.

In the next step S4, the output of the card detector 12 is checked to determine whether or not a time card has been inserted into the card pocket 2. This routine is repeated until the insertion of the time card is detected, and when the insertion of the card is detected, step S5
Then, the card feed motor 20 is started in normal rotation.
As a result, the time card inserted into the card pocket 2 is sucked into the guide groove (not shown) by the feed roller (not shown). Next step S
At step 6, the personal code recorded on the card passing through the installation position of a card reader (not shown) is read.

In the next step S7, print stage position data is read from the processing status data of the corresponding work category in the working memory 32 based on the work shift code input from the shift selection key. In step S8, the output of the card stage position detector (not shown) is checked to sequentially detect the print position of the time card that is being drawn into the back of the guide groove by the feed motor (not shown), and the current position of the time card is detected. When the printing stage position matches the printing stage position data read above,
Stop the card feed motor. As a result, the time card is set with respect to the printer 7 at a stage position corresponding to the printing stage position data of the corresponding work shift and becomes stationary.

In the next step S9, a personal file (not shown) corresponding to the personal code read from the time card in step S6 is transferred to the working memory 32.

In the next step S10, the working memory 3
Based on the personal file transferred to 2, the processing status data of the corresponding work category, and the current time data (card acceptance time) of the clock register, various calculations are performed to obtain the necessary employment data, and the results of the calculations are used to calculate the The file is updated and returned to file memory (not shown).

In step S11, print data to be printed on the printing section of the time card 13 is edited in the working memory 32 based on the above calculation result. For example, if the card acceptance time is recognized as the normal work start time in the calculation processing step S10, the print data may be stored in the work start time data A1 in the personal file as data corresponding to the date printing column of the printing section of the time card. The month and day data of are set, the data of the work classification register is set as the data corresponding to the work classification printing field, the hour and minute data of calculation A1 are set as the data corresponding to the attendance time printing field, and the other printing The data corresponding to the column is not set (it becomes blank).

Further, if it is recognized in step S10 that the employee is leaving work normally, the leaving time data in area A4 is set as the print data corresponding to the leaving time stamp field, and other data is not set. Furthermore, when arriving at work, if it is recognized that the employee is late or leaving early, in addition to the above, a code representing late arrival or early leaving is set as print data corresponding to the exception code printing field. In addition, if you are recognized as leaving early or working overtime when leaving work,
In addition to the above, a code indicating early leaving or overtime is set as print data corresponding to the exception code printing field, and in addition, in the case of overtime or the above-mentioned early work, the total time data of the early work time and overtime time for that day is set. is set as the print data corresponding to the overtime work time printing field.

In the next step S12, the print data edited in step S11 is printed by the printer 7 at a predetermined column position (set in step S8) of the time card. That is, by driving the printer moving motor M to move the printer head in the width direction of the card and sequentially driving the printing magnets in accordance with the print data, the corresponding data is printed in a predetermined printing field. be. When printing is completed, the process proceeds to step S13, where the card feed motor 20 is reversed to eject the time card from the card pocket 2, and the process returns to step S3.

In this way, the management data shown in FIG. 5, which represents the working time system of each of the plurality of work classifications in a predetermined format, is stored in the memory 32, and a 1-minute pulse is generated from the clock circuit 35 to display the management data. When the time is updated, processing status data for each work shift is updated based on the management data. Then, when the time card is inserted and the code corresponding to each shift is input using the shift selection key, the personal code is read from the time card and the work shift code inputted. According to the processing status data of the file and the corresponding work shift, each work data related to the card acceptance time is obtained, predetermined items are printed on the card, and the card is discharged.

Although the printing operation on the time card is controlled by the above procedure, details of the print processing procedure based on the print position control mechanism adopted in the present invention will be explained with reference to FIGS. 8A to 8D. do.

First, in step S21, the print column number of the time card is calculated based on the current time and the column movement time of the setting table shown in FIG. 5 stored in the working register 32. That is, if the current time is 9:30, the following control is performed to move the print position of the printer head to the second column of the "on-time attendance column" corresponding to area A2. In step S22, initial processing for print position control is executed. That is, the 8th
As shown in step S22,1 in Figure B, first,
It is determined whether the printer head is at the origin or not.
The printer moving motor M is driven as in steps S22 and 2 until the origin position is reached. When the origin position is reached, the content of the detection counter that counts the number of times the print field partition detector 10 passes the detection plate 11 is cleared to zero as in steps S22 and 3. After the initial process is completed in this way, the process moves to print position control. In this print position control, first, as shown in step S23,1 in FIG. 8C, it is determined whether the detector 10 has detected the detection plate 11. If it is not detected, the printer moving motor M is driven to move the detector 10, which moves integrally with the printer 7, to detect the detection plate 11, as in steps S23 and 2. When the detection plate 11 is detected in this way, the count value is set to 1 by incrementing the content of the detection counter by +1 as in steps S23 and 3. Next, in step S2, check whether the counted value of this detection counter and the print field number match.
3 and 4, and in this case, the print field No. is "2", so it is determined that there is a mismatch, and steps S23 and 2 are performed again.
The printer drive motor M is driven as shown in FIG. As a result, if the detector 10 detects the next detection plate 11 in step S23,1, the content of the detection counter is incremented by +1 in step S23,3. Since the detection counter already has a count value of 1 due to the above-described operation, the count value becomes "2" by this +1 increment operation.
Therefore, a match is determined in steps S23 and S4. When the printing position control is completed in this way, a predetermined printing process is performed on the time card in step S24,1, as shown in FIG.
In steps 4 and 2, it is determined whether or not the printing is finished. If the printing is not finished, the printing process is repeated until the printing is finished, and when the printing is finished, step S2 is performed.
4. Stop the printer moving drive motor M at 3.
Terminate all print processing control means.

〔effect〕

As explained above, the time card printing position control device according to the present invention can use a commercially available normal motor as the motor for moving the printer instead of the conventional expensive scanning motor. The entire structure can be constructed at low cost, and the printer is equipped with a moving position detector, and the printing position of the printer is controlled based on the number of times the detector passes through a plurality of detection plates provided in the detector moving path. By adjusting the movement of the detection plate, the printing width can be easily changed without storing it in memory and changing the printing program, and it has the advantage that it is easy to change the use of time cards with different printing column widths.
