Field of the Invention The present invention relates to a stepping motor control device for driving a card conveying mechanism, and more particularly to a stepping motor control device for driving a timing card conveying mechanism of a timer. [Prior Art] For example, a timer generally used for managing the working hours is a configuration in which a card transport mechanism that transports a time card inserted into a card insertion slot to a predetermined position is transported by a card transport mechanism. As a driving source of the timing card conveying mechanism of such a timer, there are many examples of using a stepping motor (also called a pulse motor) because of the advantages of being suitable for properly controlling the rotation angle and the long service life (for example, Patent Document 1) The timer disclosed in Patent Document 1 is located below the insertion opening of the time card, and has a card detection switch that operates when the front end of the inserted time card is pushed up. Then, based on the detection of the timing card caused by the card detecting switch described above, the card transport mechanism transports the timing card to the determined position. [Problem to be Solved by the Invention] However, in the control of the card transport mechanism of the timer of Patent Document 1, -4-200813895, the card transport speed is accelerated. When the time card is ejected, the card is detected to be turned up and down, and the card detection switch that is temporarily turned off may be turned ON again, which may cause the start of the inhalation operation of the time card. The present invention has been made in view of the above problems, and an object of the invention is to provide a stepping motor control device capable of achieving accurate and stable card transport control in order to increase the speed of the card transport operation. Means for Solving the Problem A stepping motor control device relating to the present invention is a stepping motor control device for driving a card conveying mechanism, which is characterized in that it is provided from a card conveying operation for discharging a card to a insertion side of the card insertion side. When the portion reaches the predetermined position, the first drive pulse is supplied to the stepping motor, and after reaching the predetermined position, the second drive pulse that is slower than the pulse speed of the first drive pulse is supplied to the drive pulse supply means of the stepping motor. Further, in the following configuration, when the card transporting operation for discharging the card is started, it is necessary to calculate the insertion side tip end portion of the card to reach the predetermined position based on the pulse speed of the first drive pulse. a calculation method of the required number of pulses of the number of pulses, and a pulse counter for calculating the number of pulses of the first drive pulse supplied to the stepping motor; the presence or absence of the predetermined position is based on the calculation result of the required pulse number calculation means And the counting result of the aforementioned pulse counter is determined. Further, it may be configured as follows: when the card transporting operation for discharging the card is started, the insertion side tip end portion of the card is calculated based on the pulse speed of the first drive pulse -5 - 200813895 a desired time calculation means for the time required for the predetermined position and a timer for counting the supply time of the first drive pulse of the stepping motor; and whether the arrival of the predetermined position is based on the calculation of the required time calculation means The result is judged by the timing result of the aforementioned timer. Further, the timepiece according to the present invention is characterized in that it includes the stepping motor control device having any of the above configurations. Further, the computer program according to the present invention is characterized in that the computer functions as follows: the first drive pulse is supplied to the drive from the start of the card transporting operation for discharging the card until the insertion end of the card reaches the predetermined position. After the stepping motor of the card transport mechanism reaches the predetermined position, the second drive pulse that is slower than the pulse speed of the first drive pulse is supplied to the drive pulse supply means of the stepping motor. EFFECT OF THE INVENTION As described above, the stepping motor control device according to the present invention adjusts the card conveying speed for discharging the card. The discharge of the card can be stabilized. Further, by using the stepping motor control device, it is possible to provide a timer that can operate at high speed. [Embodiment] Hereinafter, an embodiment of a stepping motor control device according to the present invention will be described with reference to the drawings. Fig. 1 is a schematic diagram showing the configuration of the timer 1 of the present embodiment with respect to the stepping motor control of the present embodiment -6 - 200813895. In Fig. 1, the 3 series timing card 2 is used for inserting the card insertion opening; 4 is the card detecting sensor for detecting when the time card 2 is inserted from the card insertion opening 3. 5 is for sucking the inserted time card 2 or a roller for pulling the inserted time card 2; 6a, 6b are a pair of left and right transport rollers. The drive (rotation) source of the 7-series roller 5 is a motor; 8 is a timing belt that conveys the driving force of the transport motor 7 to the roller 5. When 9a and 9b are inhaled, the time card 2 reaches the deepest suction position, and is used as a pair of card detection sensors for detection. The conveyance motor 7 is a stepping motor (pulse motor) that rotates in a determined step unit in accordance with the pulse signal (drive pulse) to be supplied. The card detecting sensors 4, 9a, 9b are for detecting the leading end portion of the time card 2, for example, a transmissive type photosensor composed of a light-emitting element and a light-receiving element (none of which is shown). Furthermore, the type of the sensor is not particularly limited, and it is also irrelevant for, for example, a reflective sensor light sensor. Alternatively, it is also possible to open the proximity sensor of the timing card 2 so that the control lever is turned ON and the switch sensor can be operated. Fig. 2 is a block diagram showing the internal configuration of the stepping motor control device 20 of the present embodiment. The stepping motor control device 20 is composed of a control unit 2 1, a drive pulse generating unit 22, a drive unit 23, a desired pulse calculating unit 24, and a pulse counter 25, and the card detecting sensors 4, 9a, and 9 b constitutes. The control unit 21 includes a microcomputer (not shown), a ROM in which a program for defining a processing program for the microcomputer is stored, and a RAM used in a work area such as 200813895, and all of the control of the stepping motor control unit 20 are executed. . Further, when the card detecting sensors 4, 9a, 9b detect the leading end portion of the time card 2, the signal from each detecting sensor is input to the control portion 21. Further, the timing card 2 performs positional information (printing position information) for printing, and a signal (printing end signal) indicating the end of the printing operation, and the main control device 3 (for example, by a microcomputer) that controls the entire timer 1 , ROM, RAM, etc.) to notify. Alternatively, the control unit 21 may be configured as a functional unit of one of the main control φ devices 30. The drive pulse generating unit 22 generates a drive pulse for rotating a drive shaft (not shown) of the transport motor 7 at a predetermined rotational speed. Further, the drive pulse generating unit 22 is constituted by, for example, a oscillating circuit of a creep mode, and the pulsation control signal from the control unit 21 can adjust the drive pulse to a desired pulse speed. The drive unit 23 controls the rotation of the drive shaft of the conveyance motor 7 in accordance with the drive pulse and the control signal from the control unit 21. The desired pulse calculation unit 24 is positioned from the current position to the position on the transport (card transport) path in accordance with the calculation command signal from the control unit 21 (for example, a position from the central axis of the roller 5 to the card suction direction of 8 mm) The number of pulses required for the timing of the timing card 2 is calculated in accordance with the pulse speed of the drive pulse generated by the drive pulse generating unit 22. Then, the calculation result is notified to the control unit 21. The pulse counter 25 counts the number of pulses of the drive pulse generated by the drive pulse generating unit 22 based on the drive pulse and the control signal from the control unit 21. Then, 'the number is counted' and the control unit 2 is notified. -8 - 200813895 As described above, the processing procedure for the card conveyance control by the stepping motor control device 20 constructed will be described based on the flow chart of Fig. 3. The card transport control process is started from the card insertion port 3 of the timer 1 into which the time card 2 is inserted, and the leading end portion of the time card 2 reaches the detection area of the card detecting sensor 4. More specifically, the card detecting sensor 4 starts when the detection signal of the leading end portion of the time card 2 is detected and input to the control unit 21. φ First, the control unit 21 sends the oscillation start signal of the suction drive pulse to the drive pulse generation unit 22. When the drive pulse generating unit 22 receives the oscillation start signal from the control unit 21, the drive pulse generating unit 22 generates a suction drive pulse for a predetermined pulse speed. Further, the control unit 21 sends a suction drive control signal to the drive unit 23. The drive unit 23 that receives the suction drive control signal is supplied to the transport motor 7 by the drive pulse generating unit 22 (step S301). When the suction drive pulse is supplied to the conveyance motor 7, the card feed mechanism (the roller 5 and the conveyance rollers 6a and 6b in the present embodiment) is driven to start the suction of the time card 2. Specifically, the drive shaft (not shown) of the transport motor 7 starts to rotate, and the driving force due to the rotation is transmitted to the roller 5 via the timing belt 8. Then, the rotation of the roller 5 is started, and the inserted timing card 2 is sucked into the inside by the conveyance rollers 6a, 6b. Then, when the leading end portion of the time card 2 reaches the deepest suction position (i.e., the deepest point) (YES in step S302), it is detected by the card detecting sensors 9a and 9b, and the detection signal is sent to the control unit 21. The control unit 2 1 receives the detection signals from the card detecting sensors 9a and 9b, and sends a shock stop signal to the drive pulse -9 - 200813895 rush generating unit 22. Thereby, the supply of the suction drive control signal is stopped (step S3 03), and the suction process of the time card 2 is also stopped. In the stop of the suction processing of the time card 2, the printing position information from the main control unit 30 is notified to the control unit 21. Next, the control unit 21 performs the timing card 2 pull-out control until the printing position (printing position) of the predetermined printing column of the time card 2 is based on the relevant printing information. φ Specifically, the control unit 2 1 sends an oscillation start signal regarding the pull-out drive pulse to the drive pulse generation unit 22. The drive pulse generating unit / 22 receives the oscillation start signal from the control unit 21 and generates a pull-out drive pulse. Further, the control unit 21 sends a pull-out drive control signal to the drive unit 23. The drive unit 23 that receives the pull-out drive control signal controls the transport motor 7 so that the drive shaft rotation direction of the transport motor 7 is reversed from the suction timing, and the pull-out drive pulse supplied from the drive pulse generating unit 22 to the feed motor 7 is supplied. (Step S3 04). • When the supply drive motor 7 pulls out the drive pulse, the drive shaft of the feed motor 7 rotates in the reverse direction during suction, and the roller 5 also rotates in the reverse direction during suction. Thereby the time card 2 is pulled out to the upper part. Then, when the time card 2 is pulled out to the printing position (YES in step S3 05), the control unit 21 sends an oscillation stop signal to the drive pulse generating unit 22. Thereby, the supply of the pull-out drive control signal is stopped (step S306), and the pull-out processing of the time card 2 is also stopped. When the pull-out processing is stopped, the predetermined information (for example, commute information) is written in the printing field of the time card 2 by the printing portion (not shown) (printing - -10-200813895 processing). When the printing process is completed (step S 3 0 7 is YE S ), the main control unit 30 sends a printing end signal to the control unit 21 . The control unit 21 receives the print end signal from the main control unit 30, and sends a first drive pulse as a discharge drive pulse and a subsequent start start signal to the drive pulse generation unit 22. The drive pulse generating unit 22 receives the oscillation start signal from the control unit 21, and generates a first drive pulse (for example, 600 pps (pulse per second)). Further, the control unit 21 sends a discharge drive control signal to the drive unit 23. The drive unit 23 that receives the discharge drive control signal supplies the first drive pulse sent from the drive motor 7 by the drive pulse generating unit 2 (step S 3 0 8 ). In this manner, the control unit 21, the drive pulse generating unit 22, and the drive unit 23 supply the first drive pulse of the transport motor 7 (step S3 0 8). After the supply of the first drive pulse is started, the roller 5 starts to rotate, and the timing roller 2 is conveyed toward the card insertion opening 3 to be discharged by the transport rollers 6a and 6b. In addition, the control unit 2 1 sends an arithmetic command signal to the desired pulse number calculation unit 24 while sending the first drive pulse as the discharge drive pulse to the drive pulse generation unit 22 and the following oscillation start signal. The desired pulse number calculation unit 24 receives the calculation command signal from the control unit 21, and calculates the number of pulses (the required number of pulses) required for the leading end portion of the time card 2 to reach a predetermined position on the transport path (step S3 09). . The predetermined position is set for the purpose of the discharge of the stable time card 2, and is the deceleration point (deceleration position) of the conveyance (card conveyance) speed of the time card 2. The deceleration position is set to a position when the timing card 2 is separated from the transport rollers 6a, 6b-11 - 200813895 (for example, a position 8 mm from the central axis of the roller 5). The required pulse number calculation unit 24 is based on The current position information (print position information notified by the main control unit 30) and the information of the deceleration position obtained from the control unit 21 are compared with the pulse speed of the first drive pulse, and the number of required pulses is calculated, and the control is notified. Part 2 1 its calculation result. Further, the control unit 21 sends a count start signal to the pulse counter 25 at the same timing when the arithmetic command signal is sent to the desired pulse number calculating unit 24. When receiving the counting start signal from the control unit 21, the pulse counter 25 starts counting of the first driving pulse (i.e., counting the number of pulses) generated by the driving pulse generating unit 22 (step S3 10). As described above, when the card transport for discharging the time card 2 is started, the control unit 21 determines the timing by using the number of pulses required by the comparison desired pulse number calculating unit 24 and the number of pulses counted by the pulse counter 25. Whether or not the insertion side leading end portion of the card 2 has been conveyed to the deceleration position (step S3 1 1 ). As a result of the above determination, when the insertion side leading end portion of the time card 2 has reached the deceleration position (YES in step S3 1 1), the control unit 21 sends an oscillation start signal to the drive pulse generation unit 22 regarding the second drive pulse. When the drive pulse generating unit 22 receives the oscillation start signal from the control unit 21, a second drive pulse (for example, 300 pps) which is slower than the pulse speed of the first drive pulse is generated. The drive unit 23 supplies the second drive pulse sent from the drive motor 7 by the drive pulse generating unit 22 (step S3 12). When the second drive pulse is started, the rotation speed of the drive shaft of the transport motor 7 is reduced, and the speed of the card transport (transport) is also decelerated. Then, when the time card 2 is separated from the transport rollers 6a, 6b and is separated from the detection area of the card detecting sensor 4, the card detecting sensor 4 sends an undetected signal to the control portion 21. When receiving the undetected signal from the card detecting sensor 4, the control unit 2 1 determines that the discharge of the time card 2 is completed (YES in step S3 13), and sends a shock stop signal to the drive pulse generating unit 22. At this point, the supply of the second drive pulse is stopped (step H S 314), and the driving of the card transport mechanism (roller 5, transport rollers 6a, 6b) is stopped. As described above, the card conveyance control process ends. As described above, in the card transport control for discharging the time card 2, the stepping motor control device 20 of the present embodiment first supplies the first drive pulse to the transport motor 7, and transports the time card 2 at a high speed. When the timing card 2 is discharged (deceleration position), the second drive pulse is supplied to the conveyance motor 7, and the conveyance speed is decelerated. As a result, high-speed card transport (transport) can be performed, and excessive force at the time of discharge can be suppressed, and the time card 2 can be discharged steadily. Further, the stepping motor control device according to the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above embodiment, the determination as to whether or not the insertion side tip end portion of the time card 2 has reached the deceleration position (the processing of step 311) is based on the desired number of pulses calculated by the desired pulse number calculating portion, and the pulse The number of pulses counted by the counter is performed, but the determination method of whether or not the insertion side tip end of the timing card 2 has reached the deceleration position is not limited thereto. For example, 13-200813895 is provided with a required time calculation unit for calculating the time required for the insertion end side of the time card 2 to reach the deceleration position based on the pulse speed of the first drive pulse, and for timing the feed motor ( The timer of the supply time of the first drive pulse of the stepping motor is determined based on the calculation result of the required time calculation unit and the timing result of the timer to determine whether or not the deceleration position has been reached. Further, a card detecting sensor Φ such as a photo sensor is disposed in the vicinity of the deceleration position, and a signal (undetected signal) from the card detecting sensor is used to determine whether or not the deceleration position has been reached. At this time, when the insertion side tip end portion of the timing card is detached from the detection area of the card detecting sensor (that is, when the chronograph card is not detected), the signal indicating this (undetected signal) is sent to A control unit of the stepping motor control device. Then, the control unit that receives the aforementioned undetected signal from the card detecting sensor determines that the insertion side leading end portion of the timing card has reached the deceleration position. φ [Simplified description of the drawings] Fig. 1 is a schematic structural view showing a timer of an embodiment of the present invention.
