DETAILED DESCRIPTION OF THE INVENTION

[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.
The present invention relates to a time stamp having a function of preventing blank printing.

[0002]

2. Description of the Related Art Conventional time stamps include, for example, a print 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 Laid-Open No. 5-18844. There is a dot printing method that uses a printing method. In either 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 drops down in the case of the print hammer system and prints the print type, 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, among the above conventional time stamps, in particular, in the case of a printer type time stamp using a dot printer as a printing means,
After the trigger lever (hereinafter simply referred to as the trigger) is pressed by the paper and turned on, it takes a little time before the printer head motor operates and the printer starts dot printing. Is fully possible,
Further, even if the paper is pulled out, the printer continues to perform the printing operation. Therefore, the pulling out of the paper before printing causes the printer to hit the blank, damaging the dots, and contaminating the platen with ink.

Further, in the case of a time stamp having a conventional numbering function, when the trigger is turned on, the number feed or the counter feed is automatically performed. A so-called number jump also occurs at the same time when the number or the counter is skipped, and there is a problem that the number of issued tickets, the slip number, and the like become out of order, which makes it impossible to accurately manage them.

Further, a conventional time stamp is provided with a card lock device for locking an inserted sheet at that position, as disclosed in Japanese Patent Application Laid-Open No. Hei 6-231326, for example, to prevent the sheet from being pulled out during printing. However, in the case of the lock by the card lock device, it is not possible to prevent the sheet from being pulled out immediately after the trigger is turned on.
It was not possible to completely solve the above-mentioned problems such as the blank hitting and the blank feeding of the number and the counter.

Accordingly, a technical problem of the present invention is to detect a time stamp or the like on a inserted paper, and to reliably detect this even if the trigger-on paper is immediately pulled out. Is to stop the printing operation and feeding of the number and the counter, and to prevent idling and the idle feeding (jumping) of the number and the counter.

[0007]

Means taken by the present invention to solve the above-mentioned technical problems are as follows.

When a sheet inserted into an insertion slot provided in the body of the time stamp turns on a trigger, a printer provided in the body also performs printing to print the time and the like on the paper surface. In

(1) If the trigger is turned off again between the time when the trigger is turned on and the printing operation of the printer is started, paper pulling detection means for detecting this as paper pulling, and paper pulling detection Printing stop means for stopping the printing operation of the printer when the means detects the removal of the paper.

(2) Trigger is turned on by insertion of paper
After the printing, card lock means for locking the inserted paper at that position at a timing before the printer starts printing operation is provided.

(3) When the trigger is turned on and the printer starts a printing operation, the number and counter adding means for performing number feeding and counter feeding, and when the ON trigger is turned off again before the printing operation of the printer,
A number for stopping the above number feeding and counter feeding, and a counter addition stopping means shall be provided.

[0012]

The means described in the above (1), (2) and (3) operate as follows.

According to the means described in the above (1), when the leading end of the paper inserted into the insertion slot turns on the trigger, the printer operates to print the time and the like on the paper surface. If the trigger is turned off by pulling out the paper before the start of the operation, the printing operation of the printer is stopped and printing is not performed, so that it is possible to prevent the printer from hitting idle.

According to the means described in the above (2), the card lock device locks the paper at a timing before the printer starts printing after the paper inserted into the insertion slot turns on the trigger. In addition to preventing the paper being pulled out during printing, if the paper is pulled out before the card lock device locks the paper after the trigger is turned on, the printing operation of the printer is stopped as described above, and the blanking is performed. In order to prevent the problem, the printer can be completely prevented from idling.

According to the means described in (3) above, when the trigger is turned on by the insertion of the sheet and the printer performs a printing operation, the number feed and the counter feed are performed together. Pull off to turn off the trigger
In this case, since the number feed and the counter feed are automatically stopped, it is possible to prevent the occurrence of number jumps due to the number or counter idle feed.

As described above, the above-mentioned technical problems can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
