Description

[Detailed description of the invention] <Field of industrial application> The present invention relates to a printing device for a time recorder that prints work data on a printed card (hereinafter referred to as a time card), and in particular to a printer using a type belt. The present invention relates to a printing device that performs printing.

<Prior art> When a time card is inserted into a card passage through a card insertion slot provided at the top of the recorder body, a time recorder prints out each print field (date) in a predetermined print position corresponding to the date of work Work data such as time data can be printed in the , attendance, leaving columns, etc.).

By the way, as a printing device for printing work data on a time card used in the above-mentioned time recorder, conventionally, as disclosed in Utility Model Publication No. 50-45367, a plurality of type wheels (print wheels) linked to a clock mechanism have been used. A mechanical type is known in which a time card is inserted between a time card and a printing hammer driven by a solenoid plunger, and printing is performed by striking the printing hammer with an impact.

Furthermore, a printing device using a dot printer has been proposed in Utility Model Application No. 56-164357, and in this printing device, work data can be printed by horizontally operating a printing head from which multiple printing wires selectively protrude. It is designed to be printed in a dot shape.

By the way, among the conventional printing devices used in the above-mentioned time recorders, the mechanical ones have a problem that the mechanical configuration is complicated and the device becomes large. The configuration is complex, and
The printing head itself is large, making the entire printing device large.Furthermore, since dot printers are expensive, the printing device becomes expensive.

Therefore, in view of the various problems mentioned above, it is conceivable to use a type belt printer, which is mainly configured in a desktop electronic computer, as a printing device for a time recorder, in place of the conventionally used printers.
This type belt printer is constructed such that a driving pulley and a driven pulley are rotatably supported near both left and right edges of a printer block, and a type belt is stretched between these two pulleys. The drive pulley is rotated via a gear by rotation of the drive motor, and the rotation of the drive pulley causes the type belt to run between the pulleys. Further, a type block consisting of numbers and symbols is formed on the surface of the type belt, and when a predetermined printing command is given to the drive motor, the type block is formed on the type belt through the pulley by the rotational drive of the motor. It is adapted to be stopped at a predetermined position on the type block.

If the above-mentioned type belt printer is used as a component of a time recorder, the mechanical structure becomes simple and it becomes possible to make the time recorder inexpensive and small.

<Problem that the invention aims to solve> Incidentally, the printing device of the above-mentioned time recorder needs to satisfy the printing area (number of printing digits) corresponding to each printing column of the card, such as date and time, clock-in, clock-out within hours, re-entering within hours, clock-out, number of hours, etc.

In other words, the printing area of the timecard needs to be close to the width of the timecard (e.g. 86mm), and the number of printing digits is 31 digits in the above format, but this can be further increased by increasing the number of printing fields. There is sex.

However, in the type belt printer described above, in order to increase the printing area (number of printed digits), it is necessary to increase the distance between the driving pulley and the driven pulley and to lengthen the type belt.
If configured in this way, the amount of elongation and contraction of the type belt and the vibration will increase, resulting in irregular printing positions and a deterioration in printing quality. Therefore, conventionally, the type belt printer has been used in desktop electronic computers, but not in time recorders.

As described above, there has been no type belt printer that satisfies the printing area (number of printing digits) required for time recorders. Therefore, as mentioned above, conventional printing devices have complicated mechanical configurations, the type head itself is large, and the printing device as a whole becomes large.Furthermore, dot printers are expensive, so the printing device The problem is that it becomes expensive. Furthermore, even if a type belt printer capable of printing a large number of digits was possible, in this printer, the print head would move to the right side of the print area because it would print sequentially to the right starting from the print start position at the left end of the print block. The printing speed will be delayed by the time it takes to move. For this reason, there is a problem in that it takes time to print, for example, an exit column in the right column of a time card.

Therefore, the present invention was proposed to solve the above-mentioned problems, and it uses a small and inexpensive type belt printer as a printing device for a time recorder, thereby reducing the size and cost of the time recorder. Without making complicated improvements to small-digit type printers, it is possible to print multiple digits (print area) that corresponds to all the print fields of time cards while maintaining the printing quality of type belt printers, and to improve printing speed. The purpose is to achieve this goal.

<Means for Solving the Problems> The present invention was proposed to achieve the above object. A printing block that prints on a printing card by selectively hitting the printing portion formed on the belt with a printing head; a slide shaft that movably holds the printing block; and a slide shaft that moves the printing block along the slide shaft. The present invention is characterized in that it includes a printing block feeding motor that slides and drives the printing block, and prints by sliding the printing block corresponding to the printing area of the printing card.

<Function> In the present invention, a print block having a print area smaller than the print area corresponding to all the print fields of a print card is slid via a slide shaft by the rotational drive of a print block feed motor, and by sliding this print block, Since the printing block is configured to print at a predetermined position in the printing area of the printing card, the printing block itself can be miniaturized.
Moreover, the price can be reduced.

Further, since the small print block is used as a component, it is possible to prevent a decrease in print quality and a decrease in print speed due to slack or shrinkage of the print belt constituting the print block.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a front sectional view of a time recorder equipped with a printing device according to an embodiment of the present invention, and FIG. 2 is a right side sectional view of the time recorder.

1 and 2, a card insertion slot 2 into which a printed card (hereinafter referred to as a time card) is inserted is provided at the top of an outer casing 1 of the time recorder. A card passage 3 extends downward so as to be continuous with the insertion slot 2. This card passage 3 is constituted by a pair of guide plates 3A and 3B arranged in parallel. Also, a printing device 20 that prints on a time card using a printer 5 using a type belt 4.
is provided on one side (front side) of the card passage 3. Also, a position on the other side of the card passage 3 and facing the printing head (approximately the printing belt 4
A platen 16 is provided at a position facing the time card, and is rotated counterclockwise in FIG. 2 by a solenoid plunger 15 against the elastic force of a tension spring during printing, so that the time card This prevents the time card from being bent.

Further, a micro switch 6 for detecting card insertion is arranged below the printer 5 to detect insertion of a time card into the card passage 3. Also, below the micro switch 6 and before and after the card passage 3, a pair of feed rollers 9 and 10 rotate around rotating shafts 11 and 12 for feeding the time card inserted into the passage 3 downward. It is movably arranged and is rotationally driven by a card feed motor 14 via a gear 13. Furthermore, below the rotation shafts 11 and 12 and on both left and right edges of the card passage 3, two sensors 18 and 1 are installed in the notch block 17 of the card passage 3.
9 are provided symmetrically. These sensors 18 and 19 are constituted by photointerrupters consisting of light emitting elements 18a, 18b and light receiving elements 19a, 19b. The above sensor 18, 19
The system detects the detected block (for example, a notch) provided at the bottom of one side of the time card to determine whether the card is inserted (front, back, or upside down), and also detects the block along the side edge of the card. It is for reading blocks to be read (for example, round holes) for determining the position of the printing stage that is formed.

Next, the configuration of the printing device 20 of this embodiment will be explained.

This printing device 20 uses a type belt type printer 5, and a print head 23 selectively prints the type portion of a type belt 4, which is spanned between a driving pulley 21 and a driven pulley 22 and driven to rotate. Printing is performed by tapping the paper. The printer block 5, which is a printing block constituting the printing device 20, is driven by a printer block feed motor 24 of a sliding mechanism, and is slid in both left and right directions in FIG. 1, as will be described later. That is, the time recorder according to this embodiment is configured such that the entire printer block 5, around which the type belt 4 is stretched, can be slid in both left and right directions by the printer block feed motor 24. As a result, the time card can be divided into left and right halves and printed by the printer 5 block which is slide-guided according to the print area of the time card. Since the present invention uses the type belt 4 having a printing area smaller than that of a time card, the printing position can be set regularly without increasing the amount of extension and contraction or vibration of the type belt 4.

Next, the slide mechanism of the printer 5 block will be explained.

As shown in FIGS. 3 and 4, the rod-shaped slide shaft 2 shown in FIG.
Two guide holes 29, 29 into which 7, 28 are inserted.
and 30, 30 are bored, respectively, and these slide shafts 27, 28 are supported so as to be slidable left and right in FIG. Note that both ends of the slide shafts 27 and 28 are supported by support frames 31 and 32 that are vertically attached to support frames 31 and 32 that are fixed to both sides of the guide plates 3A and 3B that constitute the card path 3. There is.

In addition, the slide shafts 27 and 28 on the right side
A mounting plate 37 is provided integrally with the support frame 31 on the outer surface of the support frame 31 supporting one end, while a support frame supporting the other ends of the slide shafts 27 and 28 is provided. Attachment plates 35 that are integrally attached to the support frame 32 are disposed on each of the support frames 32 . A disk-shaped induction pulley 38 is provided on the mounting plate 37, and the printer block feed motor 24 is provided on one of the mounting plates 35, and a drive pulley 36 is mounted on the motor shaft of this motor 24. It is provided. A driving wire 40 is stretched between the driving pulley 36 and the guiding pulley 38, and the motor 24 rotates the wire 40 so as to run between the pulleys 36 and 38. The printer 5 block is provided with a wire fixing piece 39 that protrudes from the front side, and the wire 40
As the printer 5 moves, the printer block 5 can slide in the left and right directions in FIG. Note that the drive printer 36 has a wire 40 wound twice to increase the frictional force.
Furthermore, a tension spring 41 is placed in the middle of the wire.
is provided to adjust the slippage of the drive printer 36.

In this way, the configured slide mechanism allows
The printer 5 block rotates the slide shafts 27 and 28 by normal or reverse rotation of the motor 24.
is guided to the left end position and the right end position. Here, the time during which the motor 24 is energized is set to be slightly longer than the time required for the printer 5 block to slide to the left end or right end position. As a result, the printer block 5 is reliably sent to the left end or right end position, and the wire 40 and drive pulley 36 are allowed to slide during the energization time, thereby eliminating the need for a sensor for determining the sliding position.

By sliding the printer 5 block left and right in this way, even if the maximum printable digits of the printer 5 is, for example, 20 digits, it is possible to print, for example, 31 digits on the time card.

Furthermore, in this embodiment, stoppers 33 and 34 having a predetermined length are provided at both ends of the slide shaft 27, as shown in FIG. The stoppers 33 and 34 are set so as to enable printing corresponding to the printing area of the time card to be printed, and in this example, they are designed to slide by a sliding range D.

By the way, an example of a time card is shown in FIG. 6, and in the print area 43 of the time card 42, the left side print area for date, attendance, and out of hours is shown.
Printing of work data in _S1 is performed with the printer block 5 sliding to the leftmost position as shown in Figure 1, and work data is printed in the right side printing area _S2 for re-entering after hours, leaving, and notes. is printed by printer 5.
This is done with the block sliding to the rightmost position. The printer 5 block stops at the left end or right end position defined by the stopper 33 or 34 by pressing a selection switch for selecting a desired print field before the time card is inserted into the time recorder.

In this way, by making it possible to stop the printer 5 block, the printing device described above is more effective than when using a type belt type printer which has the maximum printing digits that can cover the entire printing area of the time card 42. The printing speed to the right printing area _S2 is improved. This is because in the case of type belt type printers, the print head scans to the right starting from the print start position at the left end of the printer and prints sequentially, so the maximum printable digit covers the entire print area of the time card 42. In the printer, the printing speed is delayed by the time it takes for the print head to move to the right printing area _S1 .

Next, the configuration and operation of the printer 5 are shown in a bottom view in FIG. 5, a schematic diagram in FIG. 7, and a diagram in FIG. 8 showing the operation.
This will be explained with reference to the schematic diagrams in FIGS.

Near the left and right edges of the printer 5 block, as shown in FIGS. 5 and 7, a driving pulley 21 and a driven pulley 22 are provided. is rotated, and due to the rotational drive of the drive motor 46,
The drive pulley 21 rotates via the gear 45,
The type belt 4 is configured to run between the pulleys 21 and 22. In addition, on the outer peripheral surface of the type belt 4 (the surface facing the platen 16),
A printed portion consisting of predetermined numbers, symbols, etc. is formed.

Further, a type belt fixing gear 47 is integrally provided on the driving pulley 21, and when an electromagnet 48 pulls a clutch 49 based on a printing command, the clutch 4 is attached to the gear 47 as shown in FIG.
9 are engaged with each other, and the type belt 4 rotating in the direction of arrow A is stopped at a predetermined printing device. Further, a drive bevel gear 50 is provided coaxially with the drive pulley 21, and when the clutch 49 is pulled based on a printing command, the hammer shaft 51
Hammer bevel gear 52 and drive bevel gear 5 attached to
0 and the hammer shaft 51 rotates.
As a result, the printing hammer 23A of the printing head 23, which is provided inside the type belt 4 and interlocks with the hammer shaft 51, pushes out the type belt 4 with an impact in the direction of arrow B, as shown in FIG. Then, when the print command is released, the clutch 49 is returned, the hammer bevel gear 52 and the clutch 49 are engaged, and a standby state as shown in FIG. 7 is established. Furthermore, when printing the next digit, as shown in FIG.
moves, and the next drive of the printing hammer 23A is performed.

Note that the selection of each printing portion to be printed is made by reading the print position detection signal output corresponding to each print portion while referring to the reference position detection signal output as the drive pulley 21 rotates. It is done by

Next, a printing device according to another embodiment will be described with reference to FIGS. 10 and 11.

In this embodiment, side plates 25 and 26 are provided on both the left and right sides of the printer 5 block,
These side plates 25 and 26 have guide holes 2.
9 and 30 are drilled, and furthermore, this guide hole 2
9 and 30, a slide shaft 55 rotatably supported by the support frames 31 and 32, and a slide shaft 56 fixed to the support plates 31 and 32.
is inserted. Also slide shaft 55
A threaded portion 57 is formed on the support frame 31 side. The length of this threaded portion 57 is approximately equal to the sliding range of the printer 5 block. Also, a nut 58 that is screwed into the threaded portion 57
is attached to the inner surface of the side plate 25. In addition, the support frame 31 and the side plate 2
Compression springs 59 and 60 are inserted between the slide shaft 55 and disposed between the slide shafts 55 and 6. Further, a printer block feed motor 61 for driving the slide shaft 55 is attached to the outer surface of the support frame 32. This motor 61 is connected to the shaft 55 via a reduction gear.

In the printing device configured as described above, when the printer block 5 is slid from the right end position to the left end position as shown in FIG. Then, the printer 5 block is positioned by the compression spring 59 and stops at the left end position.

Further, in order to slide the printer block 5 from the left end position to the right end position, the motor 61 is reversed and the nut 58 and threaded portion 57 are screwed together by the elastic force of the spring 59. When the printer 5 block is slid to the right end position, the screw portion 57 and the nut 58 are idle, and the 11th
It is positioned by a compression spring 60 as shown in the figure. Here, the energization time to the motor 61 is set to the time required for the printer 5 block to slide to the left or right plus the margin time, and the above-mentioned mechanism eliminates the need for a sensor for setting the stop position. It's getting better.

In this manner, since the time recorder printing apparatus described in the above two embodiments uses the type belt type printer 5, the configuration is simple and the apparatus can be made smaller. Also printer 5
Since it is inexpensive, an inexpensive printing device can be provided.

Furthermore, by making the printer 5 block slidable as described above, printing speed is improved.

<Effects of the invention> According to the invention, since a type belt type printer is used, the configuration of the printing device is simpler than that of a printing device using a mechanical type or a dot printer.

In addition, since type belt type printers are compact in size, even if the printer block is configured to slide from side to side, the printing device will not become bulky, and the printer block can be moved with low driving force. be able to.

Furthermore, since the printer block is made slidable, it is possible to print twice as many digits even though a printer that prints with fewer digits is used. Furthermore, by sliding the printer block, it is possible to improve the printing speed in the right side printing area (lower digit printing area) of the printing area of the time card.

In addition, type belt type printers are less expensive than dot printers, and by using a printer that prints with a small number of digits, the above-mentioned printing device can be constructed at a low cost.

Furthermore, since the present invention does not adopt a configuration that increases the distance between the driving pulley and the driven pulley, problems such as belt extension and contraction are eliminated.
The print area can be expanded without deteriorating print quality.
