Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings.

FIG. 1 shows the electrical configuration of the time recorder 1. As shown in FIG.

The microcomputer 2 receives a clock signal S1 from the clock signal generator 3, a card insertion signal 5IO from the rotation detector 23 forming the card insertion detection device 62, a card position signal S2 which is a pulse signal from the card position detection device 4, A correction signal coming from the operation panel 5 through the decoder 17,
A date setting signal, a bell ringing time signal and other various control signals S3, and an irregular code signal S4 indicating information such as leaving early, going out, being late, etc. from the irregular human power device 6 are input, based on a preset program. Then, a display signal S5, a bell ringing signal S6, a first drive signal S7, and a second drive signal S9 for driving the display device 7 and the thermal print head 9 are output in accordance with the date, hour, minute, and other control contents.

The display signal S is sent as a segment signal S8 via the driver circuit 10 to a segment type display device 7 using, for example, a light emitting diode and to, for example, a segment type thermal print head 9 of a printing device 8.

The drivers 11 and 12 drive the display device 7 and the thermal print head 9 with the second drive signal S, respectively, when necessary.

Further, the bell ringing signal S6 is manually inputted to the driver 13 to drive the bell 15.

Further, the first drive signal S7 operates a motor 31 that drives a drive solenoid 16 of the printing device 8 and a card feeding device 18, which will be described later.

Next, the mechanical structure of the time recorder 1 is shown in FIG. 2, and is composed of a card feeding device 18, the aforementioned card position detecting device 4, a printing device 8, and a card insertion detecting device 62.

The card feeding device 18 is connected to the card insertion slot 20 of the case 19.
The card passage 30 extends from the lower card outlet 21 to the lower card outlet 21.
A card detection lever 22, a rotation detector 23, a feed roll 24, a holding roller 25, a guide 26 for forming a card path, a feeding roll 27, and a holding roller 2 are provided at that portion.
It is constructed by arranging 8.

The drive chain 61 is rotated by the motor 31 to drive the feed rolls 24°27.

The card detection lever 22 is rotatably supported with respect to the case 19 by a pin 29, and has one end corresponding to the card passage 30 and the other end corresponding to the rotation detector 23.

The rotation detector 23 detects the rotation of the card detection lever 22 using a magnetic detection means using a combination of a magnetic body and a Hall element, a photoelectric detection means using a combination of a light source and a light receiving element, or the like.

Both feed rolls 24 and 27 are driven by a motor 31.

The holding rollers 25 and 28 are respectively connected to the swing lever 3.
2.33, and moves toward and away from the feed roll 24.27.

These swing levers 32.33 each have a shaft 34.3
5, and is connected to the drive plate 40 by pins 36, 37 and elongated holes 38, 39.

The drive plate 40 is constantly pulled upward by a spring 58 that is applied to the hammer drive lever 45.

Therefore, in the initial state, the feed roll 24.27 is separated from the holding roller 25.28, and the drive solenoid 16
The relationship is such that it is driven in a downward direction by energization.

The printing device 8 is constructed by placing a hammer 41 opposite the thermal print head 9 in the middle of the card path 30.

Here, the hammer 41 is urged leftward by a spring 59 and further supported by an arm 42 and a support shaft 43, and the hammer drive lever 45 and link 44 are connected by pins 46 and 47.

The hammer drive lever 45 is rotatably supported by a support shaft 43 and connected to the drive plate 40 by a pin 48.

Therefore, in the initial state, the hammer 41 is moving to the left and is in pressure contact with the thermal print head 9.

Next, the card position detection device 4 is composed of a fan-shaped pulse plate 49 and a photoelectric detector 50.

The pulse plate 49 is rotatably supported by a shaft 51 and is always positioned above the passage by a spring 60. One end of the pulse plate 49 is located in the card passage 30 and is connected to the thermal print head 9.
A card rest 52 to be locked is formed at the lower end of the card, and holes 53 for generating small pulsed light are formed in the arcuate portion, the number of which corresponds to the number of days in January.

A photoelectric detector 50 is provided for this hole 53.

The irregular human power device 6 includes an irregular card 55 that stores specific codes such as leaving early, going out, being late, etc., a guide 56 to insert this, and the irregular card 5.
It is composed of a reading head 57 for reading 5 irregular code signals S4.

Next, the operation will be explained along the flowchart of FIG.

First, when the power is turned on, all circuits are reset.

Next, the operation panel 5 is operated to perform the start-up operation, that is, to set the month, date, and time, in the same manner as in the case of a clock, and to set the time at which the bell will ring.

Then, the microcomputer 2 updates the month, day, and time based on the clock signal from the adjusted time, outputs the display signal S5 and the second drive signal S corresponding to this updated time, and displays the display signal on the display device 7. The month, day, and time are displayed, and the thermal print head 9 also heats the segments in accordance with the month, day, and time.

In this state, when the card 54 is inserted from the card insertion slot 20, the card detection lever 22 constituting the card insertion detection device 62 is pushed by the card 54 and rotates counterclockwise.

The rotation detector 23 detects the rotation of the card detection lever 22 and outputs a card insertion signal 810.

Then, the microcomputer 2 outputs the first drive signal S7 based on the input of the signal StO, and starts the motor 31 and the drive solenoid 16.

Therefore, the feed rolls 24 and 27 are rotated in the direction of the arrow, and at the same time the drive plate 40 is lowered, so that the swing lever 32
．． 33 rolls around shafts 34 and 35, holding rollers 25,
28 is pressed against the feed roll 24, 27.

Then, the card 54 is moved between the feed roll 24 and the holding roller 2.
5, the card rest 52 is pushed downward, and the pulse plate 49 of the card position detection device 4 is rotated clockwise.

At this time, the photoelectric detector 50 detects a light pulse from the hole 53 and sends it to the microcomputer 2 as a card position signal S2.

Here, the microcomputer 2 outputs the card position signal S2.
The number of pulses is counted, and when the number of counted values corresponding to the update date is output, the output of the first drive signal S7 is interrupted.

Due to this interruption of the first drive signal S7, the drive solenoid 16
Then, the motor 31 stops operating for a certain period of time, that is, the print recording time.

Accordingly, the drive plate 40 is returned to its initial state by the spring 58, and the hammer 41 presses the card 54 against the thermal print head 9 during the recording period.

Further, the thermal print head 9 heats the segments in correspondence with the date, month, day, other symbols, etc. based on the second drive signal S output from the microcomputer 2 at this time and the display signal S5. Then, those matters are recorded on the heat-sensitive card 54 as a branding iron.

During this recording, the card feeding device 18 has returned to its initial state, so that the holding rollers 25 and 28 are pressed against the corresponding feeding roll 2.
4.27, the card 54 is temporarily stopped.

After a certain recording time, the microcomputer 2
The output of the drive signal S7 is restarted.

Therefore, the drive solenoid 16 and the motor 31 are operated again, and the card 54 is fed by the card feeding device 18 and exits from the card ejection port 21.

When the end of the card 54 comes off the card detection lever 22, the output of the card insertion signal S1o from the rotation detector 23 stops, and when the card 54 is ejected, the card abutment 52 stops outputting the card insertion signal S1o.
Since the pressure on the pulse plate 49 is released, the pressure on the spring 6 is released.
The card rest 52 is rotated clockwise by the elastic force of 0, and is stopped when the card rest 52 is locked to the lower end of the thermal print head 9, returning to the state before the card 54 was inserted.

At this time, the microcomputer 2 detects the return of the pulse plate 49 using the photoelectric detector 50, detects the ejection of the card 54, and stops outputting the first drive signal S7.

Therefore, the drive of the motor 31 and the drive solenoid 16 is stopped, the card feeding device 18 is stopped, and the hammer 41 is pressed against the thermal print head 9.

In this way, the state returns to the state before the card 54 was inserted.

Note that since the card 54 has a length that spans the entire length of the card passage 30, when the end of the card comes off the feed roll 24, the leading end has already reached the feed roll 27, and the card 54 is always attached to one of the feed rolls 24. 27.

Furthermore, when the irregular card 55 is inserted into the guide 56, the irregular code signal S4 is read by the reading head 57, so the display signal S5 also includes a mark signal corresponding to this irregular code. , and corresponding marks such as leaving early, going out, and being late can also be printed.

The microcomputer 2 also compares the set bell-ringing time with the time, and if they match, it outputs a bell-ringing signal S6 and causes the bell 15 to ring via the driver 13.

In the above embodiment, the rotation detector 23 is configured to output the card insertion signal SIO while detecting the card 54, but it may also be configured to output the card insertion signal StO in a pulsed manner only when the card 54 is inserted. good.

In the present invention, a lot of information and various control signals necessary for recording are processed in an orderly manner by microcomputer programs, so this time recorder can be used for many purposes, and data such as date and time can be displayed digitally. Therefore, the exact time is known, and the digital signal is also used as a drive signal for the printing device, so there is no need for signal conversion for display and printing as in the case of conventional mechanical systems. The time control function, which is processed using the complex mechanism of the mold, can be processed purely electronically by a program, and the number of electronic components and wires used can be reduced, resulting in miniaturization and easy assembly.
