Description

[Detailed description of the invention] [Industrial field of application] The present invention is used in the field of time recorders, and specifically, the time card inserted into the recorder from the card pocket is transferred to the printer. This invention relates to an improvement of a card guide for a time recorder that guides the card in the direction of.

[Conventional technology]

In an electronic time recorder that uses a dot printer to print on the time card, the time card inserted into the card pocket is sent to a predetermined printing stage position by a feed roller attached to the card guide, and then printed by the printer. After treatment,
The mechanism is such that the time card is sent back to its original insertion position by a feed roller, but in conventional electronic time recorders of this type, a very narrow guide passage for the time card was installed vertically in the plastic guide plate. A structured card guide was used to guide the time cards.

[Problems to be solved by the invention] However, the card guide using plastic guide plates as described above has multiple plastic plates stacked on top of each other to create gaps between the guide passages.
There is a problem that the structure is very complicated and costs high, and the frictional resistance of contact with the time card is high.Moreover, recent time cards are made thinner, so it is difficult for the time card to be stuck in the guide path. If you insert a wet time card by mistake, the time card will stick to the guide surface and the card will not be able to be fed. There were all kinds of problems that I thought would go away.

Therefore, the technical problem of the present invention is to accurately guide the inserted time card to the position of the feed roller, while also allowing the feed roller to feed the time card with less frictional resistance. To provide a card guide for a time recorder which can smoothly carry out card feeding of time cards.

[Means for solving problems]

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

(1) Guide edges that guide both edges of the time card are bent on both sides of the guide plate that guides the inserted time card to the position of the feed roller.

(2) The guide surface of this guide plate shall have at least two protruding ribs that contact the back of the inserted time card.

However, the feed roller here is a roller that sends the time card inserted along the guide plate toward the printer, and after the printer finishes printing, reverses the direction and sends the time card back to the original insertion position. means.

[Effect]

The above means works as follows.

The above element (1) allows the guide edges to guide both sides of the inserted time card, allowing the time card to be inserted accurately up to the position of the feed roller and the card to be fed without any trouble.

The element (2) above is to keep the back side of the inserted time card away from the guide surface to reduce contact friction resistance as much as possible, and to ensure that the time card is fed smoothly by the feed roller without being stopped midway. In addition, even if a wet time card is accidentally inserted, the card can be surely fed with low contact friction resistance.

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.

〔Example〕

Hereinafter, preferred embodiments of the time recorder card guide according to the present invention will be described in detail with reference to the accompanying drawings.

In the figure, the reference numeral 1 indicates a guide plate made entirely of, for example, an electrogalvanized steel plate. The recorder is installed between the card pocket inside the recorder and the printer (both not shown). Reference numerals 4a and 4b are guide edges formed by bending the left and right edges of the guide plate 1 inward, respectively, and the time card T (see Fig. 1) inserted from the card pocket can be folded between the left and right edges of the guide plate 1. It is guided by the guide edges 4a and 4b, and the back side is guided by the guide surface 1a of the guide plate 1, and is inserted downward. 5 is a feed roller attached to the drive rotation shaft 6, 7 is a tension roller facing this feed roller 5, and 8 is attached to a wide attachment part 9 connected to one of the guide edges 4a. A card detector is shown. This card detector 8, which is attached to sandwich the guide passage 1b of the guide plate 1 from the front and back, has a light emitting element 8a and a light receiving element 8b built in on both the front and back sides, as shown in FIGS. 3 and 5. When the time card T is inserted between the two elements 8a and 8b and the card is detected, a detection signal is generated to start the drive motor (not shown) of the rotary shaft 6, rotate the feed roller 5 in the forward direction, and record the time. Card T
The printer is configured to transport the printer toward the lower printer. The drive motor that rotates the feed roller 5 is controlled by an electronic control device mainly composed of a microcomputer, and the feed roller 5 is inserted in cooperation with the tension roller 7. The time card T is fed into a predetermined printing position, and then, after printing by the printer, the feed rotation is performed again to send the time card T back to the original insertion position, but this point is outside the scope of the present invention. Since there is, a detailed explanation will be omitted.

Next, reference numerals 10 and 10 in the figure indicate ribs, which are the most important components of the present invention. They are protruded parallel to the direction. In the embodiment shown in FIG. 1 and FIG. 2, the two left and right ribs 10, 10 are formed protrudingly, but this is just an example of implementation, and two or more ribs 10 are arranged side by side. Various embodiments are conceivable, such as forming a plurality of ribs 10 having different lengths, or forming a plurality of ribs 10 having different lengths at intervals in the vertical and lateral directions. In addition, each of these ribs 10 usually has a fourth
As shown in the figure, the guide plate 1 is constructed by protruding from the back side onto the guide surface 1a, but it is also conceivable to construct the guide plate 1 by adhering a separately manufactured elongated rib member onto the guide surface 1a. Furthermore, the height of each rib 10 from the guide surface 1a is formed to be slightly lower than the height (thickness) of the guide edges 4a, 4a, as shown in FIG.

In addition, 9a and 9b in the figure are the upper and lower bent edges of the mounting part 9 to which the card detector 8 is attached, and the time card T
Upper and lower bent edges 9a, which are formed by bending the upper and lower edges of the mounting portion 9 extending above the guide passage 1b outward as shown in the figure,
9b, the problem that the time card T, which is transported up and down within the guide passage 1b by the feed roller 5 and the tension roller 7, is stopped by the upper and lower edges of the attachment part 9, can be avoided. It can be resolved.

Since the time recorder card guide according to the present invention has the above-described configuration, the time card T inserted from the card pocket into the guide passage 1b of the guide plate 1 has both side edges aligned with the left and right guide edges 4a, 4b. The time card can be guided by the ribs 10, 10, and can be moved up and down with its back side supported by the ribs 10, 10 and spaced apart from the guide surface 1a.Also, even if a wet time card is accidentally inserted, The ribs 10, 10 prevent the card from coming into close contact with the guide surface 1a, and it can be moved up and down in the same way as a normal time card.

〔effect〕

As described above, according to the time recorder card guide according to the present invention, the inserted time card can be accurately guided to the position of the feed roller,
By reducing the contact friction resistance during feeding as much as possible,
It has the advantage of being able to feed time cards without any problem even in the case of time cards with thin paper or wet time cards, and is also economical in that the entire guide can be constructed from a single metal plate, resulting in a significant cost reduction. Although the structure is simple, it is highly practical, especially as a card guide for an electronic time recorder.
