Abstract

PURPOSE:To enable a principal part to be used commonly and besides to achieve reduction of a development cost by a method wherein by judging automatically a class of a paper feed mechanism in a card printer, printing control corresponding to each paper feed mechanism is performed. CONSTITUTION:When started, a controller 1 sees a state of an input port of a printer selective signal to discriminate whether it is a mechanical system or an electrical control system and when the mechanical system, sets '1' to a mechanical system flag. When the electrical control system, the controller, sets to '0'. Then, if this flag is '1', a using paper feed mechanism is judged to be an electrical control system paper feed mechanism 3, and a printing data is transferred to a printing drive circuit 2a of a printing part 2. Then, if a timing signal is inputted, whether one line content data has been transferred or not is judged. If not transferred, a next printing data is prepared. If transferred, a printing completion signal is outputted. Then, whether transfer of all data is completed or not is judged. If transfer of all data is not completed, the procedure is returned to the input of the printer selective signal. If completed, printing control is ended.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a printing device that prints data on a card.

[Conventional technology]

In the past, the paper feed mechanism was made integrally with mechanical structural parts, and the printing section and the paper feed mechanism were switched and controlled.In addition, a separate electric control mechanism such as a stepping motor was installed to control the timing of paper feed, etc. There was something in control.

[Problem to be solved by the invention]

By the way, mechanical paper feed mechanisms are usually designed to be used in low-cost products such as calculators, while electrically controlled paper feed mechanisms are designed to be used in slightly more sophisticated products such as cash registers, printers for personal computers, and printers for word processors. Since the two systems are intended to be applied to high-cost products, there are differences in the data they print and the patterns they display, so they are used differently, and a shared system has not been considered. In addition, the various products for which the system is developed have various requirements, such as whether printing is necessary or not, and the degree of printing content, depending on the usage situation. The problem was that both were difficult. The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a printing device that can automatically determine the paper feeding mechanism to be used and perform printing control. [Means for Solving 11j] In order to achieve the above object, the present invention provides a printing section that prints data on a card, a paper feeding mechanism that moves the card to a printing position, and a paper feeding mechanism that controls the paper feeding mechanism. In a printing device consisting of a paper feed drive circuit, it is determined whether there is a paper feed drive circuit and if there is a paper feed drive circuit, print data is sent to the printing unit when a print request is received from the paper feed drive circuit to a card. The apparatus is equipped with a determination means that outputs a print completion signal to the paper feed drive circuit when printing is completed, and immediately transfers the print data to the printing section if the above judgment result indicates that there is no paper feed drive circuit. .

[Operation] According to the present invention, it is possible to determine the presence or absence of a paper feed drive circuit and perform printing control based on this determination. When there is a print request from the paper feed drive circuit, the print data is transferred to the print unit, and if there is no paper feed drive circuit, it is determined that the paper feed mechanism is mechanical and the data is immediately transferred to the print unit. It is possible to automatically adapt to the type of paper feeding mechanism used.

【Example】

The present invention will be explained below with reference to Examples. FIGS. 1(a) and 1(b) show a system with an electrically controlled paper feed mechanism and a system with a mechanical paper feed mechanism according to the present invention, respectively, and the controller 1 is composed of a microcomputer. , a boat that transfers print data to a print drive circuit 2a that drives a print mechanism 2b of the print section 2, and a boat that takes in a print timing signal from the print drive circuit 2a to set print timing, and an electric control system. A boat that takes in a printing device selection signal to determine whether the paper feeding mechanism 3 is a mechanical paper feeding mechanism 4 or a mechanical paper feeding mechanism 4, and a printing request signal from the paper feeding drive circuit 5 of the electrically controlled paper feeding mechanism 3. It is equipped with a boat and an output port for supplying a print completion signal to the paper feed drive circuit 5, and is compatible with an electrically controlled paper feed mechanism 3 or a mechanical paper feed mechanism 4. The controller 1 performs printing control operations based on the flowchart shown in FIG. 2 in accordance with the paper feeding mechanism used. This printing control operation will be explained. First, when starting, the controller 1 looks at the state of the input port of the printing device selection signal, determines whether the mechanical method is the electrical control method based on the presence or absence of the printing device selection signal, and if it is the mechanical method, the mechanical method flag is flagged. is set to "1", and if the electrical control method is used, the mechanical method flag is set to "0", and if this flag is "1", the paper feeding mechanism being used is an electrical control method. 3, and transfers the print data to the print drive circuit 2a of the print section 2. If a timing signal is input, it is determined whether one line of data has been transferred, and if it has not been transferred, it prepares for the next print data, and if it has been transferred, it outputs a print completion signal. Next, it is determined whether all data transfer has been completed,
If all data transfer is not completed, the process returns to the input of the printing device selection signal, and if the transfer is completed, printing control is ended. On the other hand, if the mechanical system flag is 0, the controller 1 determines that the paper feeding mechanism being used is the electrically controlled paper feeding mechanism 3, and then waits until a print request signal is received from the paper feeding drive circuit 5. stand by. When a print request signal is sent from the paper feed drive circuit 5, the controller 1 transfers the print data to the print drive circuit 2a of the printing section 2. If a timing signal is input, it is determined whether one line of data has been transferred or not. If it has not been transferred, the next print data is prepared, and if it has been transferred, it is printed to the paper feed drive circuit 5. A completion signal is output, and then it is determined whether or not all data transfer has been completed.If all data transfer has not been completed, the process returns to inputting the printing device selection signal, and if complete, printing control is ended. In this manner, the printing apparatus of the present invention automatically determines the type of paper feeding mechanism and performs printing control corresponding to each paper feeding mechanism. The third section shows an electronic sphygmomanometer incorporating the printing device of the present invention, in which a compression band 6 is inserted into the upper arm of the person being measured, the power switch SW is turned on, and a start button 7 is pressed.
When is pressed, the blood pressure meter measuring means 9 inside the main body 8 shown in FIG. This is done by the blood pressure determination means 16. When the blood pressure measurement is completed, the blood pressure value is displayed on the display section 10 made up of a display element such as an LCD. When the measurer presses the memory button 11, the blood pressure value can be stored in the blood pressure value storage means 12. It is also equipped with a clock and pulse measurement means, and can simultaneously store the current time, date, and pulse value. Also, if you select and store it with the user selection switch 19,
Data for three users can also be classified and stored. Next, when printing on a card using the printing device 17 of the present invention, printing data of 1 data, 10 data, and 30 data can be designated by the printing mode setting switch 18 consisting of a slide switch. When a card is inserted into the card insertion slot 20 with the one-data printing mode specified, the printing device 17 is activated and prints only one data of the current measurement value. The measurer can manage blood pressure fluctuations without using the blood pressure value storage means 12 by printing the measurements every measurement or every day. When printing with 10 data print mode set,
Ten data of the user corresponding to the setting of the user setting switch 19 of the blood pressure value storage means 12 are printed at once on a new card in order from the newest one. When new cards are successively inserted into the card insertion slot 20 with the 30 data print mode set, the data for 30 times will be printed one after another. Here, the device shown in Fig. 3 can also store the measurement time.
The data can be printed by classifying it by user's measurement time (for example, morning, day, night, etc.). 55th! I(a) to (c) show the configuration of the paper feed mechanism 4 of the printing device 17 and the printing machine $12b. When a card 29 is inserted into the card insertion slot 20, the transmission type light receiving sensor 21 is activated. The insertion of the card 29 is detected by the transmitted light of the light emitting element 22, and the stepping motor 23 is started under the control of the controller 1. The rotation of the stepping motor 23 is controlled by the paper feed rollers 26 and 27 via gears 24 and 25.
and is transmitted to the belt 28. The card 29 is moved by the rotation of the paper feed rollers 26 and 27 from the position A at the time of insertion, and the printed mark etc. is read by the reflective optical sensor 3o, and it stops when it reaches the predetermined printing position. Blood pressure value data is printed by the printing mechanism 2b. When printing a plurality of pieces of data at once, printing and movement are repeated a predetermined number of times, and when printing is completed, the stepping motor 23 rotates in the reverse direction and the card 29 is ejected. Figures 6-9t! 1 shows the printed state of the card 29, and FIG. 6 shows the state of the new card 29 before printing, and there are marks at the blank mark position M7 and the used card position M on this card 29. Not entered. FIG. 7 shows a state in which only one measurement value is printed in the one-data printing mode. In this case, one data has already been written, so the blank mark position M. A mark has been written on the card, but there are 9 blank spaces left, so the card used mark position is M. is not marked. In the 10-data print mode or the 30-data print mode, when the card 29 in the state shown in Fig. 7 is inserted, if a mark is written at the blank mark position M, the blank space is less than 10, so , because it is not possible to print all 10 data at once.
By providing this blank mark position M, the card 29 is taken out from the card insertion slot 20 without printing.
It is possible to reduce extra time such as searching for margins in item 9. FIG. 8 shows a case where a new card 29 is inserted in the 10-data print mode, but the blood pressure value storage means 12 stores only data for four times. Bank printed mark M in 1 data printing mode. is entered, but in the case of Figure 8, 1w is printed only on the last line.
A mark is written in the blank paper mark position M+, but since there are 6 lines of blank space left, no mark is written in the card used mark position M. This card 29 is 10
In data printing mode or 30 data printing mode, it cannot be used again. However, when inputting data in 1 data printing mode, the mark at blank mark position M1 is detected, and the last printed mark that appears next is detected. The mark M is searched and the data is printed on the next line along with the card used mark. Therefore, the card 29 shown in FIG. 8 can print data for six consecutive times in the one-data printing mode. When printing of 10 lines of data is completed in the 1-data printing mode, a used card mark is finally written at the card used mark position M, and the card 29 is taken out. By doing this, it is possible to omit filling in the bank printed mark, thereby saving time. FIG. 9 shows a state in which 10 pieces of data are printed at once on a new card 29 in the 30 data print mode or the 10 data print mode, and in this case, the card used mark position M
2, this paper cannot be used in all modes. By providing this card used mark position M2, extra printing time such as searching for a blank space can be reduced. By the way, the sensor section consisting of the above-mentioned transmission type light receiving sensor 21 and light emitting element 22 is also located at the rear of the printing mechanism 2b.
The sensor section located on the front side in the card movement direction is used as the first sensor section, the rear sensor section is used as the second sensor section, and the paper feeding roller that is the card feeding means is used for printing. One set each is placed before and after the mechanism 2b, and the distance between them is set to be shorter than the length La of the regular card 29 < (Lb)L, and the paper feed rollers 26 and 27 on the card insertion slot 20 side are connected to the first card. The paper feeding rollers 26' and 27° on the rear side are used as the second card feeding means. Then, in the controller 1, the first . The second card feeding means is operated by the driving of the stepping motor 23, and when the card detection output of the first sensor section disappears before the card detection output is generated from the second sensor section, the stepping motor 23 is reversed. The card is then ejected. In other words, if a short, irregularly shaped card or a torn card is inserted, it can be automatically rejected. In addition, the width of the card insertion slot 20 is made larger than the card width to serve as the introduction part for the card 29, and a guard is installed at the position of the printing mechanism 2b to reduce the width to the limit so as to reduce wobbling relative to the card width. It may be provided. Incidentally, FIG. 10 is a perspective view showing a schematic structure of the printing mechanism 2b and the paper feeding mechanism 4.
