[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time stamp used for printing the entry / exit time at a parking lot, printing the reception time of a delivery slip, and the like.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time stamp printing apparatus for performing printing by operating printing means in accordance with insertion of a printing card.

[0002]

2. Description of the Related Art Conventional time stamps include, for example, a printing hammer system using a character ring as disclosed in Japanese Patent Application Laid-Open No. 58-92587, and a dot printer as disclosed in Japanese Utility Model Application No. 3-77219. There is a dot printing method that uses a printing method. In each case, a trigger lever (contact point) that determines the position of a printing card (paper) inserted into the upper surface of the slide plate and that triggers a printing operation is provided. When the trigger lever is pressed by the tip of a print card that is protruded and inserted along the slide plate, the print block descends in the case of the print hammer system and prints the print characters, and in the case of the dot print system Is a mechanism for printing on the card surface by the operation of the dot printing mechanism.

[0003]

However, the size and layout of the print card used for the time stamp vary widely, and as shown in FIG. There is also a print card provided with, but in the case of a print card having a print column up to the vicinity of the leading end in this way, even if an attempt is made to print, the trigger lever hits the type block or the printer block and disturbs the print column, so Printing was not possible.

That is, FIG. 15 is a schematic configuration diagram showing the structure of a conventional time stamp.
Is a print block such as a dot printer, and T is a trigger lever. If the position of the trigger lever T is slid to a position smaller than the A dimension, the print block hits the print block and cannot be printed. Unless the position is larger than the size, there is a problem that printing cannot be performed.

Further, as shown in FIG. 16, the trigger levers T, T are arranged outside the moving range B of the dot printing block P at intervals C so as not to hit the dot printing block P.
It has been conceived that the position of the trigger levers T, T may be moved forward to enable printing near the leading end of the print card. However, in this case, the print card having a width smaller than the interval C is considered. In this case, since the trigger levers T, T cannot be pressed, there is a problem that the width of the print card to be used is limited to one wider than the interval C.

Further, in the conventional time stamp, since the print card is printed immediately when the trigger lever is pressed, if the print card is inserted obliquely as shown in FIG.
As shown in (b), there is a problem that the printed image is bent obliquely, and even if the print card is inserted straight,
If the printing card moves even a little before printing, there is a problem in that printing is performed out of the printing field in which printing is determined, or characters that are obliquely bent are printed as shown in FIG.

[0007] Therefore, a technical problem of the present invention is that the printing by the time stamp can be performed near the leading end of the print card without being disturbed by the trigger lever, and the print is obliquely bent with respect to the print card. It is to do it straight and accurately without.

[0008]

Means taken by the present invention to solve the above-mentioned technical problems are as follows. When the print card inserted along the slide plate of the lower case presses the trigger lever, the operation switch is turned on, and the printing means provided on the upper case descends to the card surface side to perform printing on the time stamp. In

Only when inserted into the stamp, the trigger arm rotates and the operation switch is turned on, and printing by the printing means can be performed without hindrance, but the print card is bent and inserted and the left and right trigger levers are unbalanced When it is pressed in a state, the support arm rotates around the center and the trigger arm does not turn on the operation switch, so that the printing by the printing means is not performed in an obliquely bent state, and is always performed. It is possible to print straight in a predetermined print field of a print card.

According to the means described in the above (3), even if the trigger lever descends and pivots to the lower side of the sliding plate in accordance with the descending operation of the trigger plate, the card lock means is inserted in conjunction with this descending rotation. Since the inserted print card is locked between the sliding plates, the inserted print card does not move due to the lowering operation of the trigger lever or the printing operation of the printing means, and the printing by the printing means is positioned by the trigger lever. It is possible to perform accurately at the print column position.

According to the means described in the above (4), when the pair of left and right card lock means descends to lock the print card with the slide plate, the rubber pieces provided on the left and right card lock means are provided with springs. Since the print card is elastically pressed by receiving the resilience of the print card, the print card can be more strongly locked without damaging the print card, thereby completely preventing the print card from moving during printing.
